Description

  The present invention relates to a positioning hardware applied to a truss and a roof surface material using the same.

  After building the building body using the framed wall method, the roof trusses are arranged at a predetermined interval to complete the hut assembly. The truss is prevented from falling down, and the roof truss is finally fixed after the truss interval of the roof truss is adjusted.

  However, according to the above conventional method, there is a problem that work efficiency is lowered because it takes time to temporarily place the roof truss on the receiving object and to install the anti-roller and to adjust the size of the truss interval of the roof truss. .

  Several prior arts have been proposed for this problem.

  For example, in Patent Document 1 below, an engagement hole or a slit is formed for each truss interval in a long ridged object formed in a mountain shape in cross section, and an engagement protrusion is provided on the upper chord material of the roof truss or a ridge bundle Disclosed is a technique for holding a plurality of trusses at each truss interval by providing an upper end protrusion of a gusset fixed to the upper end of the gusset and fitting an engagement hole or slit into the engagement protrusion or the upper end protrusion. Has been. In addition, there is also a technology for holding a plurality of trusses at each truss interval by forming a pair of engaging projections by cutting and raising each truss interval on the ridge hardware, and sandwiching the upper chord material of the truss between these engaging projections It is disclosed.

  However, since it is necessary to position individual trusses with respect to the long building hardware that has a length that allows all trusses to be connected, the "one (building hardware) vs. many (all trusses)" Positioning work must be done in relation. That is, as a work procedure, all the trusses are temporarily fixed first, and then the operation of adjusting the truss interval with the ridge hardware is performed. For this reason, all trusses must be temporarily held vertically until the building hardware is mounted, and careful work is required.

  Further, for example, Patent Document 2 below discloses a technique for adjusting a truss interval by bridging a long truss holding hardware between upper chord members of adjacent trusses. Specifically, hook-shaped claws are formed at both ends in the longitudinal direction of the truss holding hardware, and these claws are locked to the side surfaces of the upper chord members of adjacent trusses. In this state, since there is no restriction in the direction away from the truss claw, the nail nail formed integrally with the truss holding metal is driven into the truss upper chord material, thereby restraining the displacement of the truss in the falling direction.

However, according to this prior art, since it is necessary to perform a nail nail driving operation for all the truss holding brackets, it takes a long working time. Further, since it is assumed that nail nails are driven into the upper chord material of a wooden truss, it is not suitable for a truss made of steel.

FIG. 2 shows a state in which the positioning hardware is mounted between the lower chord members of the truss. Further, FIG. 3 shows a longitudinal sectional view taken along line 3-3 in FIG.

  As shown in these figures, the roof truss 10 is configured in an isosceles triangle shape, and a plurality of roof trusses 10 are spanned at predetermined intervals between the upper end portions of the left and right wall panels 14 constituting the outer wall of the building 12. By joining, the frame of the roof set 16 of the building 12 is constituted. The wall panel 14 includes a pair of upper and lower frame runners 18 (not shown) disposed horizontally and parallel to the upper and lower ends of the panel, and between the upper frame runner 18 and the lower frame runner. A plurality of studs 20 that are bridged and arranged vertically at a predetermined interval in the longitudinal direction of the upper frame runner 18, and a plywood 21 that is attached to the outer surface (surface on the outdoor side) of these structural members, And a plaster board (not shown) attached to the inner side surface (the indoor side surface) of these structural members. The upper frame runner 18 and the lower frame runner are made of channel steel, and the stud 20 is made of channel steel with a lip. However, the cross-sectional shape of the steel material is not limited to this.

  A head joint 22 is disposed on the upper frame runner 18 of the wall panel 14 described above, and the end side of the roof truss 10 is joined to the head joint 22 so as to be orthogonal to each other in plan view. In the roof truss 10, the upper chord material 24 is disposed on the oblique side, and the lower chord material 26 is disposed on the bottom side of the roof truss 10. Note that both the upper chord member 24 and the lower chord member 26 are made of channel steel with a lip. The end portion in the longitudinal direction of the lower chord member 26 is placed on the upper surface of the head tether 22, and the upper chord member 24 passes over the end portion in the longitudinal direction of the lower chord member 26 and is outside (outside) the wall panel 14. Is overhanging. The upper surface of the head joint 22 corresponds to the “truss installation surface” in the present invention.

  The front portion of the longitudinal end portion of the upper chord member 24 and the longitudinal end portion of the lower chord member 26 are disposed so as to face each other in the vertical direction, and both are joined by a pair of gusset plates 28. The gusset plate 28 is formed of a flat plate and has a trapezoidal shape when viewed from the front side of the roof truss 10. Further, the upper chord member 24 and the lower chord member 26 are connected vertically by a plurality of bundle members 30. In addition, the bundle member 30 is also comprised by the grooved steel with a lip.

  Further, the end portion side in the longitudinal direction of the roof truss 10 is joined to the upper end portion of the wall panel 14 by an unillustrated tilt stopper. This restricts the roof truss 10 from being tilted in the direction of falling by the wind.

  Here, as shown in FIG. 1, a plurality of the roof trusses 10 described above are erected at a predetermined truss interval t. A truss scaffolding / truss connecting member 40 is bridged between the lower chord members 26 of the pair of opposed roof trusses 10, which will be described in detail below.

  This truss scaffolding / truss connecting member 40 includes a positioning hardware arranged in parallel with the direction orthogonal to the lower chord member 26 as a longitudinal direction, a pair of truss connecting members 42 as connecting members for the lower chord member, and these trusses. And a face member 44 spanned between the upper surfaces of the connecting members 42.

  The truss connecting member 42 is formed based on a lip-shaped channel steel, and includes a web 42A, a pair of upper and lower flanges 42B and 42C bent in the same direction from the upper and lower edges of the web 42A, An upper lip (not shown) and a lower lip 42D that are bent in directions approaching each other from the front ends of the flange 42B and the lower flange 42C, and a pair of projecting portions 42E that project from both longitudinal ends of the upper flange 42B. And a pair of bent portions 42F that are bent and suspended from the front end portions of the overhang portions 42E. The web 42A and a pair of upper and lower upper flanges 42B and 42C correspond to the beam portions in the present invention, and a bent portion 42F and one end portion 42A1 in the longitudinal direction of the web 42A to be described later, and the other end portion 42A2. It corresponds to a locking part.

  The longitudinal dimension L of the web 42A is substantially coincident with the truss interval t. Further, the beam formation H of the web 42A is set higher than the beam formation h of the lower chord material 26. Further, the length M obtained by adding the upper flange 42B and the pair of projecting portions 42E is substantially equal to the distance T between the outer surfaces of the opposed lower chord members 26. Accordingly, the length of the overhanging portion 42E is substantially equal to the length of the upper flange 26A of the lower chord material 26. Further, the length of the face material 44 in the truss arrangement direction (longitudinal direction of the head joint 22) is substantially coincident with the longitudinal dimension L of the web 42A.

  As shown in FIG. 3, in a state where the bent portions 42 </ b> F at both ends of the truss connecting material 42 having the above configuration are locked to the upper flange 42 </ b> B of the lower chord material 26, the lower flange 42 </ b> C is the lower flange of the lower chord material 26. It is arranged below 26B. The ceiling member 44 is supported in a suspended state on the lower flange 26B via a plurality of field edges 48. A heat insulating material 48 is laid on the ceiling surface material 44.

  (Action / Effect)

  Next, the operation and effect of this embodiment will be described.

  After the wall panel 14 is installed, the roof truss 10 is suspended by a crane and installed so as to be bridged between the head joints 22 at the upper ends of the left and right wall panels 14. After the first roof truss 10 is installed, the second roof truss 10 is installed in the same manner with a predetermined truss interval.

  At this time, in this embodiment, the truss interval of the facing roof truss 10 is adjusted to a predetermined truss interval t as follows.

  First, after the two roof trusses 10 are arranged to face each other, as shown in FIG. 2, the truss scaffolding / truss connecting material 40 is bridged between the lower chord members 26. That is, the truss scaffolding / truss connecting member 40 is mounted with the pair of opposing lower chord members 26 as one set.

  Specifically, while the pair of truss connecting members 42 are inserted into the gaps between the opposed surfaces of the lower chord member 26 facing each other, the pair of overhanging portions 42E provided at both ends of each truss connecting member 42 are inserted into the lower chord member 26. The upper chord material 26 is placed on the upper flange 26A of the lower chord member 26 from above, and the pair of bent portions 42F are engaged with the web 26C. In a state where the pair of bent portions 42F are locked to the outer surface of the web 26C of the pair of lower chord members 26, one end portion 42A1 in the longitudinal direction of the web 42A of the truss connecting member 42 is the upper lip of the one lower chord member 26. Then, the lower chord member 26 comes into contact with the lower lip and is substantially sandwiched between the corresponding bent portions 42F. Similarly, the other end portion 42A2 of the truss connecting member 42 contacts the web 42A of the other lower chord member 26, and the other lower chord member 26 is substantially sandwiched between the corresponding bent portion 42F.

  In other words, the positions of the roof trusses 10 are adjusted so that both ends of the pair of truss connecting members 42 are locked to the opposed lower chord members 26 in this way. When the truss scaffolding / truss connecting member 40 is completely mounted between the opposed lower chord members 26, the distance between the two roof trusses 10 is equal to the predetermined truss distance t. Thereby, the space | interval of a pair of facing roof truss 10 is adjusted to the predetermined truss space | interval t by one-touch operation. The truss spacing of the remaining roof trusses 10 is adjusted in the same manner.

  In particular, according to the present embodiment, it is not necessary to perform a nail nail driving operation for each truss upper chord member as in the prior art described above, so that the operation time of the truss interval adjusting operation is shortened. Further, unlike the above-described other prior art, it is not necessary to simultaneously mount a single piece of building hardware on all trusses, so that the truss spacing can be easily adjusted.

  As described above, when the truss scaffolding / truss connecting member 40 according to the present embodiment is used, when the steel roof truss 10 is arranged at the predetermined truss interval t, the adjustment work of the truss interval t is facilitated and the operation is performed. It is possible to achieve both time reduction.

  In the truss scaffolding / truss connecting member 40 according to the present embodiment, the face member 44 is bridged between the upper surfaces of the pair of truss connecting members 42, so that the member 44 is used as a working scaffold during construction. be able to. As a result, according to the present embodiment, it is possible to improve the construction efficiency and the safety in addition to facilitating the adjustment work of the truss interval and shortening the work time.

  The above effect will be supplementarily described below in relation to the proportionality shown in FIG. FIG. 4 shows a configuration in which the base end portion 50A of the truss connecting member 50 made of channel steel is pivotally supported by a rivet 52 on the lower chord member 26 of one roof truss 10. In this case, the base end portion 50A of the truss connecting member 50 is pivotally supported by the rivet 52 at the factory, and then rotated around the rivet 52 so as to be covered with the lower chord member 26 to reach the building site. transport. And after installing this roof truss 10 and the roof truss 10 adjacent to this, the truss joint material 50 is rotated around the rivet 52, and the tip portion is attached to the lower chord material 26 of the other roof truss 10 with the rivet 54. Join.

  In this case, it is necessary to join the tip of the truss connecting member 50 to the lower chord member 26 of the other roof truss 10 with a rivet 54 during construction (when assembling the truss). Workability is poor. However, according to the present embodiment, since the face material 44 serves as a scaffold, workability is improved and safety is improved.

  In the case of this comparison, the truss connecting material 50 is placed on the lower chord material 26 and transported from the factory to the building site. Therefore, it is necessary to arrange the truss connecting material 50 while avoiding the diagonal material and the bundle material 30 of the roof truss 10. Therefore, there is a disadvantage that it takes time and effort when designing the production of the roof truss 10. However, according to this embodiment, the truss scaffolding / truss connecting member 40 can be attached to and detached from the lower chord member 26 of the roof truss 10. Therefore, there is also an advantage that the production design of the roof truss 10 is not affected.

  The face material 44 not only serves as a scaffold during construction, but the face material 44 can also be used as a ceiling base or a shed storage floor after construction.

  Furthermore, in the truss scaffolding / truss joint member 40 according to the present embodiment, the roof truss 10 is positioned only by locking the bent portion 42F of the truss joint member 42 to the lower chord member 26 of the facing roof truss 10 from above. be able to. Therefore, the truss interval of the roof truss 10 can be easily adjusted, and as a result, the work time of the adjustment operation of the truss interval can be further shortened.

  Further, in the truss scaffolding / truss connecting member 40 according to the present embodiment, the beam forming H of the web 42A of the truss connecting member 42 is set higher than the beam forming h of the lower chord member 26 to be locked, that is, Since the web 42A of the truss connecting material 42 is extended downward to lower the position of the lower flange 42C, the lower flange 42C of the truss connecting material 42 is below the lower chord material 26 when the truss scaffolding / truss connecting material 40 is mounted. Since it arrange | positions in the state protruded below the flange 26B, the ceiling surface material 56 can be supported by the lower flange 42C. For this reason, the hanging hanger of the ceiling base used conventionally can be abolished.

  For reference, a conventional hanging hanger 58 is shown in FIG. Conventionally, the hanging hanger 58 is fixed to the lower chord material 60 via the bracket 62, and the ceiling surface material 56 is supported via the field edge 66 to the field edge receiver 64 supported by the suspension hanger 58. According to this embodiment, the hanging hanger 58 is not necessary.

  Furthermore, by comprising in this way, since the heat insulating material 48 can also be supported together with the ceiling surface material 44, a storage is also improved very much.

  [Second Embodiment]

  Hereinafter, the second embodiment of the positioning hardware according to the present invention will be described with reference to FIGS. In addition, about the same component as 1st Embodiment mentioned above, the same number is attached | subjected and the description is abbreviate | omitted.

  The second embodiment is characterized in that the truss scaffolding / truss connecting member 40 described in the first embodiment is provided with means for preventing the roof truss 10 from rolling.

  In the example shown in FIGS. 6 and 7, a long hole 70 is formed in the vicinity of the edge portion of the face member 44 spanning the upper surface of the pair of truss scaffolding and truss connecting members 40, and an angle is formed in the long hole 70. An anti-locking hardware 72 as an anti-locking means is attached with a thumbscrew 74. A wing screw 74 is inserted in the center of the base 72A of the anti-locking hardware 72, and the wing screw 74 is screwed in a state of passing through the long hole 70, so that the anti-locking hardware 72 is positioned at a predetermined position of the long hole 70. It is fixed. Also, the rising portion 72B of the anti-roll metal 72 rises vertically from the edge of the face material 44 and abuts against the bundle 30 in a surface contact state. The rising portion 72B is fixed to the bundle 30 with bolts 76 and nuts. The base portion 72A and the rising portion 72B are reinforced with a right-angled triangular rib 72C.

  (Action / Effect)

  According to the above-described configuration, the pair of truss scaffolding / truss joint members 40 are laid over the opposed lower chord members 26 to adjust the space between the trusses, and then the thumbscrews 74 are loosened, and the locking hardware 72 is slid along the long holes 70. It is made to attach to the bundle material 30. Then, after tightening the thumbscrew 74 to fix the base 72A, the rising portion 72B is fixed to the bundle 30 with bolts 76 and nuts. As a result, the roof truss 10 is prevented from falling and the roof truss 10 is unlikely to fall down. Therefore, the fall of the roof truss 10 can be effectively prevented.

  In particular, in the above example, the anti-roll metal fitting 72 is disposed so as to be slidable with respect to the face material 44 by the slide mechanism.

  Instead of the example shown in FIGS. 6 and 7, the anti-skid 80 shown in FIG. 8 may be used. The anti-rotation 80 is formed in a rod shape that can be expanded and contracted, and hooks 82 and 84 are provided at both ends. Both hooks 82 and 84 are locked to pins 86 and 88 erected on the side of the truss scaffolding / truss connecting member 40. One hook 82 may be detachably locked with respect to the pin 86, or may be formed in an annular shape and pivotally supported so as not to be removed. The other hook 84 can be locked to a pin 89 erected on the side surface of the bundle 30. Further, a lock mechanism and a moderation mechanism (not shown) are disposed inside the anti-skid 80, and the other cylinder 80B can be pulled out at a predetermined pitch with respect to one cylinder 80A.

  According to the above configuration, after the pair of truss scaffolding and truss connecting members 40 are laid over the opposed lower chord members 26 and the truss interval is adjusted, the other hook 84 is removed from the pin 88 and the locked state by the lock mechanism (not shown) is established. The other cylinder 80B may be released from the one cylinder 80A, and the other hook 84 may be engaged with the pin 89 erected on the side surface of the bundle 30. When the locked state of the locking mechanism is restored in this extended state, when the hand is released from the anti-roller 80, it becomes a single rigid rod-like member, and exerts a resistance against the displacement of the roof truss 10 in the falling direction. Therefore, the same operation and effect as the example shown in FIGS. 6 and 7 can be obtained.

  In addition, although this locking stopper 80 was comprised so that expansion-contraction was possible, you may comprise not only this but the rod-shaped member which does not expand-contract.

  Further, both the truss scaffolding / truss connecting member 40 and the face member 44 may be provided with anti-roll means.

  [Third Embodiment]

As a result, the positioning hardware 100 has a rotationally symmetric shape and can be fitted to the other overhanging portion 100C of another positioning hardware 100 adjacent to one overhanging portion 100B.

  (Action / Effect)

  According to the above configuration, after the roof truss 10 is suspended, the positioning hardware 100 is bridged between the upper chord members 24 of the facing roof truss 10 from above. At this time, the pair of projecting portions 100B and 100C formed at both ends of the main body portion 100A are placed on the upper flange 24B of the upper chord member 24, and the pair of bent portions 100D and 100E are the upper lip 24D and web 24A of the upper chord member 24. To lock. Since the bent portions 100D and 100E are formed with the return portions 100F and 100G, while the bent portions 100D and 100E are slid along the upper lip 24D and the web 24A, the return portion 100F is moved to the upper lip 24D. Lock. At this time, the other folding parts 100E of the fall prevention pieces 100H and 100I and the adjacent positioning metal piece 100 are brought into contact with the web 24A and the upper lip 24D of the upper chord material 24. Thereby, the truss space | interval between the roof trusses 10 which oppose is adjusted to t. Therefore, as in the first embodiment described above, when the steel roof truss 10 is arranged at a predetermined truss interval t, both the adjustment of the truss interval t is facilitated and the operation time is shortened. You can plan.

  In addition, since the fall prevention pieces 100H and 100I are integrally formed on the main body 100A in the positioning hardware 100 according to the present embodiment, the fall prevention pieces 100H and 100I are the roof trusses after the positioning hardware 100 is mounted. 10 is in contact with the web 24A and the upper lip 24D of the upper chord member 24 to restrict the displacement of the roof truss 10 in the falling direction. As a result, according to the present embodiment, it is possible to suppress or prevent the roof truss 10 from being displaced in the falling direction, in addition to facilitating the adjustment operation of the truss interval and shortening the operation time. The bent portions 100D and 100E also contribute to preventing the roof truss 10 from falling over.

  Furthermore, the positioning hardware 100 according to the present embodiment is formed in a rotationally symmetric shape, and by fitting the overhanging portion 100C of the other positioning hardware 100 to the notch portion adjacent to the overhanging portion 100B of one positioning metal 100. A plurality of positioning hardware 100 can be continuously arranged in the truss arrangement direction in the same plane. For this reason, unevenness due to the positioning hardware 100 being bridged between the upper chord members 24 of the roof truss 10 does not occur. Therefore, when a rectangular flat roof material is attached, stress concentration due to unevenness is unlikely to occur on the roof material. As a result, according to this embodiment, the durability of the roof surface material can be maintained well (not impaired).

  Further, when the positioning hardware 100 is discontinuously arranged (for example, when positioning hardware (tether for truss upper chord material) is alternately arranged), the truss interval is adjusted at the same position of the upper chord material 24. However, according to the present embodiment, since the plurality of positioning hardware 100 are continuously arranged in the truss arrangement direction, the truss interval can be adjusted at the same position of the upper chord member 24. Therefore, according to this embodiment, the positioning accuracy of the truss interval can be improved.

  Further, as shown in FIG. 11, the positioning hardware 100 having the above-described configuration is integrally mounted in advance in the vicinity of the upper end portion and the lower end portion of the roof surface material 102, whereby the roof surface material 102 is attached to the upper chord material 24. The mounting function can be added. For this reason, the roof surface material 102 can be made into a panel material (panel formation) with added value instead of the board material of a fence. As a result, it is possible to form a roof panel straddling between the upper chord members 24 of the pair of facing roof trusses 10 facing each other. It is possible to improve the workability by shortening the construction work and shorten the construction period. In the case of the example shown in FIG. 11, a notch 104 is formed at a position overlapping the projecting portions 100 </ b> B and 100 </ b> C of the positioning hardware 100 on the roof surface material 102.

  In the above-described embodiment, the return portions 100F and 100G are provided in the folded portions 100D and 100E, but it is not always necessary to provide them.
