Description

  The present invention relates to a mount for fixing a solar cell module to an installation location.

  In order to increase the amount of power generated by receiving as much sunlight as possible, the solar cell module has generally been installed on the roof or roof of a sunny building. In recent years, in addition to these, photovoltaic power generation has attracted attention as a use of a vast idle land.

  When installing the solar cell module, for example, after laying a foundation on the installation surface as necessary, a pair of front pillars and a pair of rear pillars are erected in a rectangular shape at predetermined positions, and the pair of receiving beams The gantry is constructed by attaching the front pillar and the rear pillar so as to be connected. For example, a front brace for connecting a pair of front pillars to each other and a pair of rear pillars as a reinforcing member for suppressing unnecessary tilting and swinging of the front pillars and the rear pillars as necessary. There are provided rear braces connected to each other, diagonal members connecting the intermediate portion of the receiving beam and the lower end portion of the rear column. In this way, after installing the gantry, the solar cell module is placed on the pair of receiving beams, screwed and fixed in the screw holes provided in advance, and various connection processes are performed, whereby the module Installation is completed.

  Since a solar cell module has a power generation amount of only about 150 to 250 (W), a large number of solar cell modules are installed in one place according to a desired power generation amount. For example, in the 3-4 (kW) class installed on the roof of a house, there are only about 20 installed, but in the medium scale of about 100 (kW), about 500 are called mega solar. In the case of a scale, the number of installations exceeds 5000. Therefore, there is a great demand for reducing the amount of work during installation. In terms of cost-effectiveness, it is essential that the initial cost for installation can be recovered in the shortest possible time due to the reduction in electricity charges and profits from power purchases. Therefore, there is also a demand for a reduction in the amount of work from this point.

  Conventionally, various proposals for reducing the initial cost have been made. For example, by forming a large number of perforations in the standing plate of the horizontal beam at regular intervals and forming two screw holes in the support plate of the fixture at regular intervals, the fastening position of the fixture with respect to the horizontal beam is fixed at regular intervals. There is one that can be adjusted by shifting each one (see, for example, Patent Document 1). In addition, there is one that can cope with the difference in the mounting pitch in the manufacturer of the solar cell module by increasing the versatility of the constituent members of the gantry (see, for example, Patent Document 2). In addition, since the solar cell module is provided with a first support member that swingably supports and a second support member that can be adjusted in length by a screw shaft, the gradient of the solar cell module can be easily adjusted. There has been proposed a stand for a solar cell module that can be constructed at a low cost and with a simple structure (see, for example, Patent Document 3).

  However, the conventional gantry constituent member as described above does not reduce the number of types of parts at the construction site, even though it increases versatility. As described above, the solar cell module is supported by, for example, a pair of receiving beams at the left and right ends, but from the viewpoint of increasing the amount of received sunlight as much as possible and reducing the installation area as much as possible, It is installed with an inclination angle of about 5 to 30 degrees with respect to the horizontal plane. Therefore, the shapes of the left and right receiving beams are different due to the inclination.

  Further, the front pillar and the rear pillar for supporting the above-mentioned receiving beam also have a shape in which the plate material is bent at a substantially right angle along the longitudinal direction, so that the shapes are different on the left and right.

  As described above, when installing the solar cell module, it is necessary to prepare different structural members on the left and right, so that the number of types of parts increases, and it is essential to check the materials at the preparation stage and at the construction site. Therefore, the improvement of work efficiency has been hindered.

  The present invention has been made in the background of the above circumstances, and an object thereof is to provide a solar cell module mount capable of increasing the work efficiency by reducing the number of types of parts. .

  In order to achieve such an object, the gist of the present invention is that a pair of front pillars having a predetermined height arranged and fixed in a rectangular shape on the installation surface of the solar cell module and a pair having a predetermined height higher than the front pillars. And four receiving members provided on the four column members for receiving the solar cell module, the solar cell module being mounted on the horizontal plane. The four column members are used for supporting the installation hole and the receiving member for the installation surface at both ends in the longitudinal direction, respectively. And a receiving member hole, and a line-symmetric structure with respect to an axis of symmetry perpendicular to the longitudinal direction.

  In this way, the four pillar members (that is, the front pillar and the rear pillar) for constituting the pedestal of the solar cell module have both the installation holes and the receiving member holes, so that both end portions in the longitudinal direction are provided. Are provided with a line-symmetrical structure of the same shape, so that both ends can be fixed to the installation surface and the receiving member can be supported. Therefore, when fixing the front pillar and the rear pillar to the installation surface, even when their fixed states are different on the left and right sides of the solar cell module, the front pillar and the rear pillar are positioned in front of them at a position on one side of the left and right sides of the solar cell module. While fixing one end of the pillar and rear pillar to the installation surface, the column member is fixed in the intended state by flipping it upside down at the position on the other side and fixing the other end to the installation surface. And they can support the receiving member. That is, the front pillar and the rear pillar are common parts on the left and right. As a result, the distinction between the pillar members located on the left and right sides becomes unnecessary, so the number of parts is reduced and the number of one kind of pillar parts used is doubled. In addition, the labor for confirmation is reduced at the time of preparing materials and construction at the site, and the work efficiency is also improved.

  In the present application, the “line symmetric structure” means not only the above-described upper and lower installation holes and receiving member holes, but also a case where holes or notches for joining with other members are provided. Means that they are all provided at symmetrical positions.

  Here, preferably, the receiving member is provided along both left and right ends of the solar cell module by connecting the front pillar and the rear pillar. When attaching the solar cell module to the gantry, it is possible to adopt a structure that supports the solar cell module at an appropriate position such as the upper / lower end side, the left / right end side, or both. It is preferable because the connecting material for connecting the rear column can function as a receiving member for receiving the solar cell module as it is.

  Preferably, in the aspect in which the connecting member functions as a receiving member, the receiving member is fixed to the front column hole and the rear column for fixing to the front column on both ends in the longitudinal direction. And a rear column hole having a line symmetric structure about a symmetry axis perpendicular to the longitudinal direction. In this way, since the receiving member also has no distinction between right and left, the number of types of parts is further reduced, the working efficiency is further increased, and the manufacturing cost is further reduced.

  Preferably, in a mode in which the connecting material functions as a receiving member, the mount of the solar cell module is fixed to the four column members on one end side and fixed to the receiving member on the other end side. Thus, a diagonal member that forms a triangle between the column member and the receiving member is provided. Also in the gantry of the present invention, it is preferable to suppress the swinging of the column member by attaching a diagonal member as conventionally performed. In this case, the column member and the receiving member are provided with mounting holes for fixing the diagonal member, and the mounting holes are also formed symmetrically with respect to the symmetry axis.

  Preferably, the receiving member receives the upper and lower ends of the solar cell module by being fixed on the front pillar and the rear pillar or on a beam connecting the front pillar and the rear pillar. . The receiving member may be configured to receive the upper and lower ends in this way.

  Preferably, the four column members and the plurality of receiving members are made of steel plates plated with a zinc-aluminum-magnesium alloy. If it does in this way, since the steel plate which gave such a plating process has extremely high corrosion resistance, it is preferable as a constituent material of the mount installed outdoors. The alloy preferably contains, for example, zinc as a main component and contains about 5 to 15 (%) aluminum and about 1 to 5 (%) magnesium. Examples of materials include ZAM (Nisshin Steel). Registered trademark) and Super Daima (registered trademark of Nippon Steel Corporation).

  Preferably, the four column members and the plurality of receiving members are L-shaped in cross section. It is preferable to use a material having such a shape for ensuring the strength and reducing the weight.

  Preferably, the platform of the solar cell module is one in which a plurality of (multiple stages) solar cell modules having a horizontally long orientation are attached along the inclination direction. The number of attached solar cell modules per frame is, for example, about 3 to 6.

  Preferably, the frame of the solar cell module is provided with a brace for suppressing swinging of the pair of front pillars and the pair of rear pillars. In addition, although the stand of the said solar cell module can also be utilized only with one unit, in order to usually configure a power generation facility of several tens (kW) to several hundreds (kW) by installing a plurality of units. Used. When a plurality of mounts are installed adjacent to each other, it is preferable to provide a mount connecting member for connecting the mounts in addition to the breath. Thereby, rocking | fluctuation and a fall of a mount frame can be suppressed further.

  Preferably, the platform of the solar cell module is for mounting the solar cell module at an angle inclined within a range of 5 to 30 degrees with respect to a horizontal plane.

  Preferably, the frame has a column receiving member made of a plate material having an L-shaped cross section fixed to a bolt projecting from the installation surface at one flat plate portion, and at another flat plate portion. It is provided so as to support the column members by being fixed to the four column members, and the column receiving members are thicker than the plate members constituting the column members and the receiving members. is there. In this way, when installing the gantry, the column support member may be fixed to the bolt, and then the column member may be fixed to the column support member with a bolt / nut or the like. At this time, a large load is applied to the column receiving member to which a large number of members are directly or indirectly attached as compared with other members, but the plate receiving member is thicker than the column member or the receiving member. Therefore, it is possible to sufficiently ensure the strength of the column receiving member while suppressing an increase in the mass of the entire material.

  The relationship between the plate thicknesses is not uniquely determined because the material of the mount, the mass of the module to be mounted on the mount, and other various conditions affect the plate thickness. It is preferably about 1.2 to 1.5 times the material.

  In addition, the method of manufacturing the solar cell module gantry includes, for example, a pair of front pillars having a predetermined height arranged and fixed in a rectangular shape on the installation surface of the solar cell module and a pair of rear pillars having a predetermined height higher than the front pillars. Four pillar members comprising pillars and a plurality of parallel receiving members provided on the four pillar members for receiving the solar cell module, the solar cell module being inclined with respect to a horizontal plane A method of manufacturing a solar cell module mount used for supporting in a state, wherein (a) a bolt standing step of standing a plurality of buried bolts on a foundation provided on an installation surface; A column receiving member fixing step for fixing the column receiving member for receiving the column member at a predetermined height position of each embedded bolt with a nut; and (c) installation on the installation surface at both ends in the longitudinal direction. Hole and receptacle A column fixing step of fixing a front column and a rear column each having a line-symmetric structure with respect to an axis of symmetry perpendicular to the longitudinal direction having both a receiving member hole for supporting a material to each of the column receiving members. It is a waste.

  In this way, the mounting of the solar cell module on the installation surface can be achieved by a manufacturing method including the step of fixing the column receiving member to the bolt standing on the foundation and fixing the front column and the rear column of the line symmetrical structure to the bolt. Provided. At this time, since both the front pillar and the rear pillar have both the installation hole and the receiving member hole and the both ends in the longitudinal direction have the same shape of the line symmetrical structure, It can be fixed to the installation surface and can support the receiving member. Therefore, when fixing the front pillar and the rear pillar to the installation surface, even when their fixed states are different on the left and right sides of the solar cell module, the front pillar and the rear pillar are positioned in front of them at a position on one side of the left and right sides of the solar cell module. While fixing one end side of the pillar and the rear pillar to the installation surface, the other end side is fixed to the installation surface at a position on the other side, thereby fixing the column member in an intended state and receiving it. The member can be supported. That is, the front pillar and the rear pillar are common parts on the left and right. As a result, the distinction between the pillar members located on the left and right sides becomes unnecessary, so the number of parts is reduced and the number of one kind of pillar parts used is doubled. In addition, the labor for confirmation is reduced at the time of preparing materials and construction at the site, and the work efficiency is also improved.

  Preferably, in the method for manufacturing a mount of the solar cell module, the front column is fixed to the front column on both ends in the longitudinal direction between the front column and the rear column fixed to the column receiving member. A receiving member fixing step of fixing a receiving member having a line-symmetric structure with respect to an axis of symmetry perpendicular to the longitudinal direction having both a front pillar hole for fixing and a rear column hole for fixing to the rear pillar. In this way, since the receiving member also has no distinction between right and left, the number of types of parts is further reduced, the working efficiency is further improved, and the manufacturing cost is further reduced.

  Preferably, the method for manufacturing the solar cell module pedestal includes a foundation placing step in which the concrete is placed by assembling a mold having the foundation provided on an installation surface, and the concrete is placed. In this way, there is an advantage that the transportation cost for the foundation work is remarkably reduced as compared with the case of transporting the foundation manufactured in advance.

  In addition, when providing a foundation in the field as mentioned above, the unevenness | corrugation may arise on the upper surface. If this unevenness is large, it takes a great deal of time to obtain a horizontal level when installing the platform of the solar cell module, or it may increase the difficulty of installation. However, in the above manufacturing method, for example, the horizontal level of the nut on the receiving side is adjusted to adjust the screwing amount in order to fix the column receiving member with the nut at each predetermined height position of the embedded bolt. Since the level can be easily obtained by simply setting and setting the column support member, the unevenness of the foundation is not a big problem. If you want to increase the adjustable amount, you can increase the protruding length of the bolt, but if the mounting position becomes too high, it will be difficult to secure the strength, so the width of this uneven adjustment is approximately ± 10 (mm) Degree.

  Preferably, the foundation is a mounting foundation that is not embedded in the installation surface. In this way, the amount of work when the foundation is formed by concrete placement on site is remarkably reduced, and there is an advantage that work efficiency can be improved. In addition, in the case of using the mounting foundation, it can be said that floating due to wind pressure and twisting due to load are more likely to occur than the embedded foundation, but those problems can be sufficiently suppressed by making the mass and volume sufficiently large. . When placing concrete on site, it is easier to transport than when pre-fabricated foundations are installed, so it can be said that there is virtually no size limitation, and even the foundation is sufficiently reliable. It is easy to ensure the property.

  Preferably, the bolt embedding step includes a drilling step of making a hole in the foundation, an anchor injection step of injecting an adhesive anchor into the hole, and a bolt insertion step of inserting a cut bolt into the hole. , Including. As described above, the horizontal level can be easily obtained by appropriately adjusting the mounting height of the column support member. Therefore, the bolt embedding step is performed if the direction of the hole to be opened in the foundation is sufficiently maintained in the vertical direction. It can be easily performed even in a single operation. The adhesive anchor is a material in which the adhesive filled in the hole is cured by a chemical reaction, whereby the bolt is physically fixed to the foundation.

  Hereinafter, an embodiment of the present invention will be described in detail with reference to the drawings. In the following embodiments, the drawings are appropriately simplified or modified, and the dimensional ratios, shapes, and the like of the respective parts are not necessarily drawn accurately.

  FIG. 1 is a perspective view showing a whole of a solar cell module mount 10 according to an embodiment of the present invention, and a module 12 attached to the frame 10 (in the figure, three pieces are attached in a direction in which long sides are oriented sideways). .) Is indicated by a broken line.

  In FIG. 1, the gantry 10 is provided on a foundation 14 placed on a relatively flat site such as a fallow land. The foundation 14 is made of, for example, reinforced concrete. For example, the foundation 14 has a thickness dimension of about 250 (mm) and a width dimension of about 600 (mm), and is a long dimension in the left-right direction in FIG. Many are provided in parallel with a length of about several tens to several hundreds (m). In FIG. 1, a part of two foundations 14 corresponding to one gantry 10 is extracted and shown.

  The above-described gantry 10 is installed on such a foundation 14, and a pair of front pillars 18 and 18 and a pair of rear pillars 20 and 20 fixed to embedded bolts 16 projecting from the foundation 14. And a pair of receiving beams 22, 22 attached to the upper ends of the front pillars 18, 18 and the rear pillars 20, 20. The three modules 12 are attached to the receiving beams 22, 22 from the back side. It is fixed with bolts.

  Each of the pair of front pillars 18 and 18, the pair of rear pillars 20 and 20, and the pair of receiving beams 22 and 22 has a shape in which a relatively long thin plate steel material is bent at a substantially right angle in the short side direction. It consists of a so-called angle material. These are, for example, alloy plated steel sheets with a thickness of about 2.3 (mm), for example, ZAM (Nisshin Steel Co., Ltd.), which is an alloy plated material in which 6% (%) aluminum and 3% (%) magnesium are added to zinc. Company registered trademark). Since this ZAM material is light and has high corrosion resistance, it is considered to be the most preferable as a mounting material for the solar cell module 12. However, the same kind of alloy plating material as well as other plating steel plates, various types of stainless steel, etc. Alternatively, materials can be used.

  Further, the pair of front pillars 18 and 18 are erected with a height dimension lower than that of the rear pillars 20 and 20, whereby the receiving beams 22 and 22 are inclined so that the front pillars 18 and 18 side is lowered. Attached. The height dimension of the front pillar 18 is, for example, about 468 (mm) on the foundation 14, and the height dimension of the rear pillar 20 is, for example, about 1025 (mm) on the foundation 14. As a result, the inclination angle of the receiving beam 22 is, for example, about 15 degrees.

  The front pillar 18 and the rear pillar 20 both have a longitudinal width dimension of the receiving beam 22 of about 80 (mm), for example, and a longitudinal width dimension of the foundation 14 perpendicular to the longitudinal dimension is, for example, 50 (mm). ) It is structured to the extent. Further, the mutual distance between the front pillars 18 and 18 and the mutual distance between the rear pillars 20 and 20 are both about half of the longitudinal dimension of the module 12, for example. For example, if the length of the module 12 is about 1645 (mm), the distance between the front pillars 18 and 18 is about 800 (mm). As a result, the module 12 is supported at two positions about ¼ from both ends in the longitudinal direction.

  The receiving beam 22 has a length dimension necessary and sufficient for mounting three modules 12, for example. For example, if the short side dimension of the module 12 is about 983 (mm), the distance between the modules 12 is about 10 (mm), and the length of the receiving beam 22 is 2969 (mm). The width dimensions of the two surfaces of the angle forming the receiving beam 22 are matched to the front pillar 18 and the rear pillar 20, and are about 80 (mm) and 50 (mm), respectively.

  A front brace 24 is attached between the pair of front pillars 18 by a bolt or the like. The front brace 24 is, for example, an angle member having a length dimension of about 844 (mm) that is slightly larger than the distance between the front pillars 18 and 18, and the width dimension perpendicular to the longitudinal direction is vertical in the mounted state. The surface facing toward is about 160 (mm) and the surface facing in the horizontal direction is about 50 (mm).

  A pair of rear braces 26 and 26 are attached between the pair of rear pillars 20 and 20 so as to cross each other. That is, one of the rear braces 26 is attached so as to connect one lower end of the rear column 20 and the other upper end, and the other of the rear braces 26 is one upper end of the rear column 20 and the other lower end. It is attached so that a part may be connected. These are attached to different surfaces of the rear columns 20, 20, that is, the front side and the back side in the longitudinal direction of the receiving member 22 so as not to interfere with each other at the intersection. The rear brace 26 is an angle member having a length dimension of about 1002 (mm), for example, and the width dimension perpendicular to the longitudinal direction is about 50 (mm) on both of the two surfaces perpendicular to each other.

  The front brace 24 and the rear braces 26 and 26 are connected to the front pillars 18 and 18 or to the rear pillars 20 and 20 so as to suppress the swinging of the front braces 24 and the rear pillars 20 and 20 and thereby increase the strength of the gantry 10. belongs to. For this purpose, the front brace 24 is attached to each of the front pillars 18 and 18 at, for example, two places, and the rear braces 26 and 26 are attached to the rear pillars 20 and 20 so as to cross each other. . A connecting member 27 extending in the direction opposite to the rear brace 26 is attached to the side of the rear column 20. Although the other end portion of the connecting member 27 is omitted in FIG. 1, the other end portion is attached to the adjacent rear pillar 20.

  Further, between the receiving beam 22 and the rear column 20, an oblique member 28 that connects an intermediate portion in the longitudinal direction of the receiving beam 22 and a lower end portion of the rear column 20 is attached. The diagonal member 28 is, for example, an angle member having a shape in which a steel plate having a length of about 1171 (mm) and a thickness of about 2.3 (mm) is bent at a substantially right angle in the short side direction. The width dimension of the two surfaces in the direction is, for example, about 50 (mm). This diagonal material is for suppressing the rocking | fluctuation in the longitudinal direction of these receiving beams 22 by comprising a triangle between the receiving beams 22 and the back pillar 20. FIG.

  2A and 2B are side views for explaining in detail the configuration of the front pillar 18 and its mounting state. In FIG. 2, the front pillar 18 is provided with a pair of mounting holes 32, 32 for mounting to the receiving beam 22 with bolts 30, 30 at one end in the longitudinal direction located on the upper end side in the drawing. The mounting holes 34, 34 similar to the mounting holes 32, 32 are also provided at the other end in the longitudinal direction located on the lower end side in the drawing, and the front pillar 18 includes the mounting holes 32, 32 and the mounting holes. 34 and 34 are provided in line symmetry with respect to a symmetry axis perpendicular to the longitudinal direction and passing through the center thereof.

  In FIG. 2, the mounting holes 34 and 34 are used for mounting the front pillar 18 to the base angle 36 with bolts 38 and 38. That is, the front pillar 18 is attached to the receiving beam 22 at the upper end portion and to the base angle 36 at the lower end portion, but the attachment holes 32 and 34 for the attachment are similarly configured.

  As shown in FIG. 1, the front pillar 18 and the rear pillar 20 have a symmetrical structure to ensure strength, or from the viewpoint of workability, they are opposite to each other, that is, facing each other. Installed. Therefore, conventionally, it has been necessary to prepare a right front pillar and a rear pillar and a left front pillar and a rear pillar, respectively. However, according to the present embodiment, since the front pillar 18 is configured to be line-symmetric in the vertical direction as described above, if the same member is prepared by inverting the right and left sides and using them upside down. It has become sufficient.

  2 illustrates the configuration of the front pillar 18, but the rear pillar 20 is also configured to be line-symmetric with respect to an axis of symmetry perpendicular to the longitudinal direction. In addition to the holes 32 and 34 through which the bolts 30 and 38 are inserted to attach the receiving beam 22, the front pillar 18 and the rear pillar 20 have holes 40 and 40 for attaching the front brace 24 and the rear brace 26, etc. (The rear brace 26 is not shown in the drawing) and holes for attaching the diagonal members 28 are provided, all of which are provided in line symmetry with respect to the symmetry axis.

  In FIG. 2, the base angle 36 to which the front pillar 18 is attached is an angle material having a shape in which a steel plate is bent vertically like the front pillar 18 and the like. For example, it is about 3.2 (mm) thicker than other members. Since the entire load of the gantry 10 is applied to the base angle 36, the base angle 36 is slightly thick so as to withstand the load.

  Such a base angle 36 is pierced by the embedded bolt 16 projecting from the foundation 14 and fixed at a predetermined position in the height direction by a pair of nuts 42 and 42. As for the height positions of the nuts 42, 42, that is, the height position of the base angle 36, the horizontal level is set so that all the embedded bolts 16 projecting from the foundation 14 have substantially the same height position. ing. In FIG. 2, 43 is a nut for preventing the embedded bolt 16 from loosening, and 44 is a reinforcing bar provided in the foundation 14. A gap of, for example, about 10 (mm) is provided between the nuts 42 and 42 positioned below and the nut 43. The horizontal level is obtained by utilizing this gap, and the unevenness adjustment of about ± 10 (mm) is possible.

  Further, the front brace 24, the rear brace 26, the diagonal member 28, the base angle 36, etc. described above are all made of an alloy plated steel plate such as ZAM similarly to the front pillar 18 and the like. Can be used.

  FIG. 3 is a diagram for explaining the configuration of the receiving beam 22 by drawing the front pillar 18 with a virtual line in FIG. In FIG. 3, the right end portion of the receiving beam 22 which is omitted in FIG.

  In FIG. 3, the receiving beam 22 has a pair of column mounting holes 46, 46, 48, 48, 50, 50, 52, 52 respectively at two positions on both ends in the longitudinal direction. Is provided. These column mounting holes 46 to 52 are provided so that the distances from both ends in the longitudinal direction are the same, and the receiving beam 22 passes through the center in the longitudinal direction and is about a symmetry axis perpendicular to the longitudinal direction. It is line symmetrical.

The column mounting holes 46 and the like are formed so that the column mounting holes 46, 46 and 50, 50 are aligned in the horizontal direction in the illustrated inclined state. Pillars mounting holes 46, 46, illustrates the horizontal line _{V 1.} Other posts mounting holes 48,48,52,52, when the lower left indicating the inclination angle of the received beam 22 in FIG. 3 that the same angle of the downward-sloping just the opposite, i.e., V _2-wire horizontal Are aligned in the horizontal direction.

  Therefore, for example, the left receiving beam 22 in FIG. 1 is mounted in the inclined state illustrated in FIG. 3, so that the horizontal column mounting holes 46, 46, 50, 50 are used for column fixing, By mounting the right receiving beam 22 in the opposite inclined state, the horizontal column mounting holes 48, 48, 52, 52 are used for column fixing. That is, by providing two types of holes in consideration of the inclination angle, the receiving beam 22 of the present embodiment shares components on the left and right. Note that the hole for attaching the diagonal member 28 of the receiving member 22 is at the center in the longitudinal direction, that is, on the axis of symmetry.

  In short, according to the present embodiment, since the front pillar 18, the rear pillar 20, and the receiving beam 22 are configured as common parts on the left and right, the number of kinds of parts is reduced, so that the part manufacturing cost is reduced. At the same time, there is an advantage that the work efficiency can be improved because the labor for distinguishing the left and right members is reduced in each of the scenes of material preparation, transportation, and construction site.

  FIG. 4 is a process diagram for explaining a manufacturing process for installing the above-described gantry 10 on the site. In the foundation placing step S1, the foundation 14 is placed by assembling a formwork and a reinforcing bar at a predetermined position and pouring concrete. In this embodiment, since the foundation 14 is an embedding foundation in which nothing is embedded, when forming the foundation 14, the installation surface is flattened, and after rolling or reinforcing as necessary, the mold A frame is enough. An embedded foundation can be used instead of the placement foundation, and in that case, the formwork and the reinforcing bar are assembled after being dug appropriately according to the amount of embedding. In addition, it can replace with the foundation placement on site and can also carry and install the foundation manufactured beforehand, and this aspect is not excluded in a present Example. As will be described later, in this embodiment, since it is possible to adjust the unevenness of about ± 10 (mm), when installing the foundation 14, if the care is taken not to exceed this adjustment range, the installation method is There is no particular question.

  Next, in the bolt projecting step S <b> 2, the embedded bolt 16 is projected at a predetermined position of the foundation 14. The embedding bolt 16 is provided by making a hole in the foundation 14 and then injecting an adhesive anchor agent therein and fixing the cutting bolt. FIG. 5 shows an implementation state of this step S2. (a) has shown the step which has inject | poured the adhesive anchor agent 56 to the embedding hole 54 provided in the foundation 14. FIG. After the injection, insert a cutting bolt as shown in (b). The cutting bolt used here is appropriately selected according to the size of the gantry 10 and the installation environment, and is, for example, M12 × L130.

  The bolt inserted as described above is physically held when the adhesive anchor agent is cured. Next, a round washer, a spring washer (not shown, see FIG. 2) and the like are fitted into the embedded bolt 16, and the nut 43 is tightened. (c) shows a state after the nut 43 is tightened.

  Next, in the base angle mounting step S <b> 3, the base angle 36 is fixed to the embedded bolt 16. FIG. 6 is a view for explaining the attachment of the base angle 36 and the attachment of the front pillar 18 or the rear pillar 20.

  In FIG. 6, in (a), a clearance of, for example, about 10 (mm) is provided on the nut 43 and the nut 42 is fitted. At this stage, the horizontal level of the upper surface of the nut 42 is obtained. As described above, there is a clearance of about 10 (mm) on the nut 43, and the length of the embedded bolt 16 is sufficient, so that as described above, the unevenness can be adjusted by about ± 10 (mm). Next, in (b), the base angle 36 is fitted from above. The base angle 36 is a relatively short angle material having a length dimension of about 80 (mm), for example, the width dimension of the portion placed on the nut 42 is about 53 (mm), and the rising dimension is about 65 (mm). It is. Since the horizontal level of the nut 42 has already been taken out, it is only necessary to tighten the nut 42 via a washer or a spring washer as appropriate after the base angle 36 is fitted. (c) shows the state after tightening.

  After mounting the base angle 36 in this way, in the front column / rear column mounting step S4, the front column 18 and the rear column 20 are used by using the column mounting holes 58, 58 provided on the vertical surface of the base angle 36. Install each. FIG. 6 (d) shows the state after attachment. Since the base angle 36 has already been mounted in a state where the horizontal level has come out, the mounting of the front column 18 and the rear column 20 does not require any effort and can be carried out by one person alone.

  Moreover, in the present embodiment, as described above, the left and right column members are made common, and therefore it is sufficient to identify the front column 18 and the rear column 20 by the length dimension in the above column mounting operation. Therefore, there is no need to identify similar members when assembling the gantry except that the left and right are different, and depending on the arrangement position, it is possible to use the same material on the left and right by flipping up and down or front and back, so work efficiency is improved. Enhanced.

  After attaching the column members 18 and 20 in this manner, in the breath attachment step S5, the front brace 24 and the rear breath 26 are each attached at predetermined positions. In the receiving beam mounting step S <b> 6, the receiving beam 22 is mounted on the front column 18 and the rear column 20. These orders can be reversed, but it is preferable to attach the brace before the receiving beam 22 is loaded. Even when the receiving beam 22 is attached, the working efficiency is improved because the left and right parts are common parts.

  Next, the diagonal member 28 is attached in the diagonal member attaching step S7, and the rear pillars 20 and 20 of the adjacent gantry 10 are connected to each other by the connecting member 27 in the rear column connecting step S8. Thereby, the gantry 10 is obtained.

  In short, according to the manufacturing method of the present embodiment, the members of the front pillar 18, the rear pillar 20, and the receiving beam 22 are configured in a line-symmetric structure so that they are shared on the left and right sides. Even at the construction stage, there is an advantage that labor for material identification is reduced and work efficiency is increased.

  As mentioned above, although this invention was demonstrated in detail with reference to drawings, this invention can be implemented in another aspect, and various changes can be added in the range which does not deviate from the main point.
