Description

  INDUSTRIAL APPLICABILITY The present invention relates to an architectural panel joining structure and method suitable for joining a panel structure to a horizontal member or a vertical member constituting a shaft of a wall, roof, or floor in a building structure, and a building including the same. Concerning structures.

  In recent years, interest in disaster prevention against disasters such as earthquakes has increased, and in particular, strengthening of earthquake resistance of building structures has been demanded. Among building structures, for building structures using building panels, it is necessary to first improve the earthquake resistance of the panels in order to enhance the earthquake resistance.

  For example, the technique disclosed in Patent Document 1 is a technique related to a load-bearing wall that has excellent seismic performance and can reduce the construction cost. In other words, a gap is provided between the upper surface of the foundation constituting the bearing wall and the lower end surface of the structural plywood so that the floor material can be arranged, and the edge portion of the floor material can be placed on the upper surface of the foundation. I have to. As a result, it is not necessary to provide a floor receiving member for supporting the floor material on the base, and the construction work of the floor can be facilitated. And the receiving material joined to both a structural plywood and a floor surface material is provided, the structural plywood and the floor surface material are connected via the receiving material, and the studs that connect the intermediate portions of the beam and the base. And the frame material is reinforced with the spacers. As a result, it is possible to give the load bearing wall a load resistance of 3 or more.

  However, since the disclosed technique disclosed in Patent Document 1 has a structure in which a plywood is directly joined to a wooden column member or beam member with a nail, the column member or beam member is applied when an earthquake force is applied. There was a problem that it was easily damaged centering on the nail driving site. In addition, the wall thickness increases by the thickness of the face material, and many materials (adjustment materials, etc.) are required to secure the accommodation of the opening, and there is a problem that the site cannot be used effectively in narrow spaces. there were.

  Moreover, in the disclosed technique of Patent Document 2, a basic skeleton structure having a rectangular frame shape is formed by joining a wooden structure with a joining member. And a base is fixed to the inward part in the said rectangular frame shape of each joining member, a shaft is each inserted between the bases of a diagonal position, and also the end of the compression coil spring is fixed to the longitudinal direction both ends of each shaft. In addition, a pressing member is provided between the anti-fixed end of each compression coil spring and the base so as to compress the compression coil spring from the anti-fixed end side to the fixed end side.

However, since the disclosed technique of Patent Document 2 has a configuration in which braces are attached to a rectangular frame-like wooden frame, it is necessary to attach hardware to the four corners of the rectangular frame. For this reason, the burden of manufacturing labor increases, resulting in an undeniable increase in manufacturing cost. Further, in the disclosed technique of Patent Document 2, since a large concentration force is generated in the brace structure, a reinforcing material for reinforcing this is particularly necessary, and the wall thickness increases accordingly. was there.

  Therefore, the present invention has been devised in view of the above-described problems, and its object is to absorb seismic energy more effectively from the viewpoint of improving the seismic performance of a building structure. It is another object of the present invention to provide an architectural panel joining structure and method that can reduce the burden of manufacturing labor without increasing the thickness of a housing such as a wall, and a building structure including the same.

  In order to solve the above-described problems, an architectural panel joining structure according to the present invention includes a frame member made of a thin lightweight steel plate formed in a U-shaped cross section composed of a flange portion and a web portion, and the frame member. A panel structure having a thin steel plate face member screwed to the flange portion or the web portion is joined to the horizontal member or the vertical member constituting the building structure via the web portion or the flange portion in the frame member. It is characterized by.

  In the present invention configured as described above, the face material is not directly joined to the column or beam, but is joined to the column or beam via the vertical frame material and the lower horizontal frame material (upper horizontal frame material). For this reason, it is possible to prevent the main structural member of the building structure such as a column or a beam from being directly damaged. Moreover, in the joint structure to which the present invention is applied, stable seismic performance can be ensured by subjecting the face material around the screw to bearing deformation when subjected to an external force such as an earthquake.

  BEST MODE FOR CARRYING OUT THE INVENTION Hereinafter, as the best mode for carrying out the present invention, refer to the drawings for an architectural panel joint structure for joining a panel structure to a horizontal member or a vertical member constituting a wall, roof, or floor in a building structure. The details will be described.

  FIG. 1 shows a joint structure in which a panel structure 1 is joined to a building structure 2 composed of columns 4 and beams 5.

  The building structure 2 is based on the premise that it is constructed by a frame construction method that supports vertical force with a frame such as a pillar 4 or a beam 5, but is not limited to this, and is constructed in a frame shape. It may be constructed based on a framed wall construction method in which the panel structure 1 is hit against a member and supported by a wall or a floor (face material). Moreover, although this building structure 2 assumes that it is a comparatively small-scale building of about 2 stories to 4 stories, for example, it is not limited to this.

  2 and 3 show the configuration of the panel structure 1 to be joined to the building structure 2. 2 is a perspective view of the panel structure 1, FIG. 3 (a) is a plan view of the panel structure 1, and FIG. 3 (b) is a cross-sectional view taken along line BB in FIG. 3 (a). Further, FIG. 3C shows a cross-sectional view taken along line AA in FIG.

  The panel structure 1 includes a frame member 16 and a face member 9. The frame member 16 is disposed over a pair of vertical frame members 11 opposed to each other at an interval and the upper end portion of each vertical frame member 11, and is joined by a screw fixing fixture (not shown) such as a drilling tapping screw. The horizontal frame member 13 and the lower horizontal frame member 14 arranged over the lower end portions of the vertical frame members 11 and joined by a screw fixing fixture (not shown) are configured in a rectangular shape.

  In the present invention, there is no reinforcing horizontal beam between the vertical frame members 11. In the present invention, the reinforcing horizontal beam is acted on by a folded plate, which will be described later, to prevent the vertical frame member 11 from being twisted.

  The vertical frame member 11 is made of a thin lightweight steel having a U-shaped cross section including an upper flange portion 32, a lower flange portion 33, and a web portion 34. Incidentally, if the face material is screwed only on one side of the shape steel, the frame material 16 may be L-shaped, and the vertical frame material 11 may be U-shaped and the web portion 34 and the face material 9 may be screwed. Further, the vertical frame member 11 may have lips formed on the leading end sides of the upper flange 32 and the lower flange 33. As the thin lightweight steel, it is a steel obtained by roll forming a thin steel plate having a thickness of 0.8 mm to 3.2 mm, preferably 1.0 mm to 1.6 mm. You may make it apply shape steels, such as a shape steel, as it is.

  The upper horizontal frame member 13 is made of a thin lightweight steel having a U-shaped cross section including an upper flange portion 42, a lower flange portion 43, and a web portion 44. The lower horizontal frame member 14 is made of a thin lightweight steel plate having a U-shaped cross section including an upper flange portion 52, a lower flange portion 53, and a web portion 54. The upper horizontal frame member 13 and the lower horizontal frame member 14 are formed in a size that allows the vertical frame member 11 to be fitted therein.

  The face material 9 is formed by bending a thin steel plate by roll forming or the like, and is connected to both ends of the upper flange 22 and the upper flange 22 and is inclined with respect to the upper flange 22. And a folded plate having a lower flange 24 connected to the web 23 and substantially parallel to the upper flange 22. As a result, the face material 9 has a shape in which trough portions 27 and crest portions 28 having a trapezoidal cross section formed by the upper flange 22, the web 23, and the lower flange 24 are alternately bent. By inclining the web 23, the amount of the face material 9 used can be reduced, and the finally produced panel structure 1 itself can be reduced in weight and cost.

  The face material 9 is joined to the frame material 16 by screwing. At this time, the valley portion 27 of the face material 9, in other words, the lower flange 24 is fixed to the frame material 16 by a screwing fixing tool 12 (not shown) such as a drilling tapping screw. As shown in FIG. 2 (c), it is desirable that the head portion of the screwing fixing tool 12 is located on the face material 9 side. When the face material 9 is actually fixed to the frame material 16, the screwing fixing tool 12 is driven from the face material 9 side so that they are joined to each other. Further, the fixing positions by the screwing fixing tool 12 are assigned along the vertical frame member 11, the upper horizontal frame member 13, and the lower horizontal frame member 14 at a predetermined interval or an arbitrary interval. The extending direction of the crest 28 and the trough 27 in the folded plate as the face material 9 is substantially perpendicular to the longitudinal direction of the vertical frame member 11.

  Incidentally, in the form of FIG. 2, the frame material 16 is described as an example in which the frame material 16 is configured in a rectangular shape by the two vertical frame materials 11, the upper horizontal frame material 13, and the lower horizontal frame material 14. It is not limited. For example, in FIGS. 4 (a) to 4 (c), in addition to the vertical frame member 11, the upper horizontal frame member 13, and the lower horizontal frame member 14, the upper horizontal frame member 13 and the lower horizontal frame member 14 are used as the frame member 16. An example of the panel structure 1a in which an intermediate horizontal frame member 17 is disposed in the middle and an intermediate vertical frame member 18 is disposed in the middle between both vertical frame members 11 is shown. 4 (a) is a plan view of the panel structure 1a, FIG. 4 (b) is a side sectional view of FIG. 4 (a), and FIG. 4 (c) is an F- F sectional drawing is shown. The face material 9 is joined to the intermediate horizontal frame material 17 and the intermediate vertical frame material 18 via the screw fixing fixture 12 in addition to the vertical frame material 11 and the upper horizontal frame material 13 and the lower horizontal frame material 14. Yes.

  In FIG. 5A to FIG. 5B, as the frame material 16, in addition to the vertical frame material 11, the upper horizontal frame material 13, and the lower horizontal frame material 14, an intermediate vertical frame material 18 in the middle of both the vertical frame materials 11. The example of the panel structure 1 which has arrange | positioned is shown. 5A shows a plan view of the panel structure 1b, and FIG. 5B shows a GG cross-sectional view. The face material 9 is joined to the intermediate vertical frame member 18 via the screw fixing fixture 12 in addition to the vertical frame member 11, the upper horizontal frame member 13, and the lower horizontal frame member 14. In this example, the extending direction of the crest 28 and the trough 27 in the folded plate as the face material 9 is substantially parallel to the longitudinal direction of the vertical frame member 11.

  Next, the details of the joint structure for joining the panel structure 1 having the above-described configuration to the columns 4 and the beams 5 in the building structure 2 will be described with reference to the drawings.

  FIG. 6A shows an enlarged view of a connecting portion between the column 4 and the beam 5. The panel structure 1 is attached to the pillar 4 and the beam 5. At this time, the vertical frame member 11 in the panel structure 1 is in contact with the column 4, and the lower horizontal frame member 14 (upper horizontal frame member 13) is in contact with the beam 5. The vertical frame member 11 is joined to the column 4 via the web portion 34. Further, the lower horizontal frame member 14 (upper horizontal frame member 13) is joined through the web portion 54 (44). Incidentally, the pillar 4 and the web part 34 may be joined by a screwing fixing tool 47 made of a drilling tapping screw or the like. Moreover, the beam 5 and the web part 54 (44) may be joined by the screwing fixture 48 consisting of a drilling tapping screw or the like. In addition, as a joining means other than the screw fixing fixtures 47 and 48, for example, a rivet or a bolt may be used. However, the screw is a more preferable joining means because it does not require a tip hole processing, is easy to join to a column with a closed cross section, and is unnecessary due to fear of deviation at a low load because there is no hole clearance. It can be said. Or you may make it join by apply | coating an adhesive agent.

  FIG. 6B shows a cross-sectional configuration when the panel structure 1 is connected to the column 4. A screw fixing fixture 12 for joining the face material 9 is fixed to the vertical frame member 11 at the upper flange portion 21, and a screw fixing fixture 47 for joining the column 4 to the web portion 34. It is fixed. Incidentally, as for this screwing fixing tool 47, it is desirable that the screw head is located inside the vertical frame material 11.

  Moreover, it is desirable that the face material 9 made of the folded plate is located in the inner c direction with respect to the outer peripheral end 4 a of the column 4. Specifically, the face material 9 includes at least the valley portion 27 of the valley portion 27 and the mountain portion 28 formed by the upper flange 22, the web 23, and the lower flange 24 being continuous. It is desirable to be located in the inner c direction from the end 4a. Incidentally, it goes without saying that the peak portion 28 may also be positioned in the c direction on the inner side than the outer peripheral end 4a.

  As described above in detail, in the present invention having the above-described configuration, when the panel structure 1 is joined to the building structure 2, the face material 9 is joined directly to the column 4 or the beam 5. Instead, it is joined to the column 4 and the beam 5 through the vertical frame member 11 and the lower horizontal frame member 14 (upper horizontal frame member 13). For this reason, it is possible to prevent direct damage to the main structural members of the building structure 2 such as the columns 4 and the beams 5.

  Moreover, in the joint structure to which the present invention is applied, when the seismic force is applied, the seismic energy can be absorbed based on the mechanism described below. As shown in FIG. 7A, when the lower flange 24 in the face member 9 and the upper flange portion 32 in the vertical frame member 11 are joined by the screwing fixture 12, an external force is applied in the arrow direction in the figure. It shall act. At this time, as shown in FIG. 7 (b), the periphery of the screw hole drilled in the face material lower flange 24 is subjected to bearing deformation. As a result, the seismic energy is absorbed by the bearing deformation. In particular, in the present invention, the point that the frame members 11, 13, and 14 are made of thin lightweight steel is an indispensable component, so that the face material around the screw hole can be easily supported and deformed according to external force. It becomes possible, and it becomes possible to improve the absorption performance of seismic energy.

  In addition, for the reasons described above, in the joint structure to which the present invention is applied, stable earthquake resistance is not affected by variations in the degree of joint on-site to the columns 4 and beams 5 as the main structural members of the building structure 2. It becomes possible to demonstrate performance.

  Further, in the present invention, since only the stress in the material axis direction acts from the face material lower flange 24 via the screw to the face material 9 to the vertical frame material 11, In addition, it is possible to create a state in which only the stress in the axial direction of the column 4, in other words, only the shearing stress in the direction perpendicular to the plane of FIG. Thereby, since it is suppressed that the force of the D direction in FIG.6 (b) generate | occur | produces, it also becomes possible to prevent that the load of a tension | pulling direction acts with respect to the screwing fixture 47. FIG. For this reason, there is no need to specially provide a column reinforcing structure for resisting the tensile load acting on the screwing fixing tool 47, and it is not necessary to provide a stiffener, thereby reducing the processing cost. It becomes possible.

  Further, in the present invention in which the frame members 11, 13, and 14 are made of thin lightweight steel, there is a gap between the column 4 and the web portion 34 in the frame member 11 as shown in FIG. Even in such a case, the web portion 34 can be deformed out of plane, and the gap can be easily filled. In the case shown in FIG. 8 as well, the column 4 and the frame member 11 are shear bonded, so that the stress transmission performance can be ensured.

  Alternatively, the panel structure 1 may be prepared slightly smaller than the interval between the pillars 4 and the beams 5 and the gap may be filled by the out-of-plane deformation of the web portion 34 described above. As a result, it is possible to avoid a situation in which the manufactured panel structure 1 cannot be inserted between the columns 4. These construction methods can be used not only for new construction but also for the case where the panel structure 1 is used for seismic reinforcement, thereby ensuring the ease of construction.

  Moreover, the case where an external force acts with respect to the panel structure 1 which comprised the face material 9 with flat plates, such as a structural plywood, is shown in FIG. In FIG. 9, the position of the screw fixing fixture 12 before deformation is indicated by a white circle, and the position of the screw fixing fixture 12 after deformation is indicated by a black circle. As shown in FIG. 9, when an external force is applied, the face material 9 is displaced with respect to the frame materials 11, 13, and 14. As a result, the face material 9 protrudes from the frame material 11 and the like at the corners. If the corner portion of the face material 9 protrudes from the frame material 11, the protruding portion hits the pillar 4 and the like, and the deformation of the panel is hindered, so it is difficult to ensure stable seismic performance.

  On the other hand, in the present invention, the face plate 9 is a folded plate made of a thin steel plate in which valley portions 27 and mountain portions 28 are alternately and continuously bent. As a result, when an external force is applied, the valley portion 27 and the mountain portion 28 of the folded plate located at the end portion are deformed out of the plane, thereby preventing the surface material from protruding from the frame material, and stable seismic performance. Securement is possible.

  In addition, by utilizing the fact that the corner portion of the face material 9 is shifted with respect to the frame members 11, 13, and 14 and the corner portion does not protrude, only the valley portion 27 of the face material 9, or the valley portion 27 and the mountain portion 28 can be positioned on the inner side of the outer peripheral end 4a of the column 4 or the beam 5. For this reason, it can prevent that the panel structure 1 protrudes outside from the outer periphery end 4a of the pillar 4 or the beam 5, and can also comprise a thin wall thickness.

  The present invention is not limited to the embodiment described above. FIG. 11 shows an example in which the column 4 is not formed of a steel pipe having a rectangular cross section, but is an H-shaped steel. In this case, when inserting the panel between the columns, the frame material hits the flange of the H-shaped steel, so it is necessary to divide the panel, and if the panel is attached to both sides of the H-shaped steel web, Although the timing of screwing the frame material must be considered, it can be realized. Incidentally, this pillar 4 may be formed by overlapping the webs of channel steel.

  FIG. 12A shows an example in which the panel structure 1 is joined between the beams 5. In such a case, as shown in FIG. 12B, the lower horizontal frame member 14 (upper horizontal frame member 13) is joined to the beam 5 only via the web portion 54 (44) as described above. Become. Moreover, the vertical frame material 11 will exhibit the function as a pillar material by sticking the back surface of the web part 34 together.

  FIG. 13A shows an example in which the panel structure 1 is joined to the wooden column 4 and the beam 5, and FIG. 13B shows the panel structure 1 to the steel column 4 and the beam 5. The example which joins is shown. Similarly, in this case, the lower horizontal frame member 14 (upper horizontal frame member 13) is joined to the beam 5 via the web portion 54 (44) as described above, and the vertical frame member 11 is connected to the column 4. It joins via the web part 34. FIG.

  In the present invention, the case where the panel structure 1 is joined to the column 4 and the beam 5 has been described as an example. However, the present invention is not limited to this. When joining the panel structure 1 to any location in the building structure 2, the joining method described above may be applied. For example, as an alternative to constructing a wall body by joining the panel structure 1 to the column 4 and the beam 5, when the panel structure 1 is joined to the beam 5 or a joist (not shown) to form a floor or a ceiling. Of course, the above-described effects can be obtained by applying the above-described joining method. That is, in the above-described embodiment, the column 4 is described as a vertical member and the beam 5 is described as a horizontal member. However, the present invention is not limited to the horizontal member and the vertical member that constitute any part of the building structure 2. Of course, the above-described technical idea may be applied when the panel structure 1 is joined.

  Moreover, in the example mentioned above, although mentioned about the case where it joins via the frame materials 11, 13, and 14 which consist of a shape steel formed in the cross-sectional U-shape, it is not limited to this. For example, as the frame members 11, 13, and 14, L-shaped steel or a section steel having a rectangular cross section may be used, or any shape steel having a flange portion and a web portion may be used.
