Description

  The present invention relates to a wall panel mounting apparatus, and more particularly to a wall panel mounting apparatus used when a wall panel such as an extruded cement is built in a through angle fixed to a beam of a building.

Conventionally, when an extruded cement board which is a hollow wall panel is built in a wall of a building or the like, first, an L-shaped through angle with a cross section of L is horizontally attached to the upper part of a floor slab side beam. Later, an extruded cement board is placed on the horizontal portion of the through angle. Next, the lower side of the stepped mounting bracket (for example, Z clip) is pressed against the vertical portion of the through angle, and the intermediate inclined portion or the lower portion of the stepped mounting bracket is welded to the vertical portion of the through angle, and The upper portion of the stepped mounting bracket is fastened and fixed to the extruded cement board with bolts (for example, see Patent Document 1).
JP 2003-090094 A

  In the above prior art, an intermediate inclined portion of the stepped mounting bracket is welded to an angle, and the upper portion of the stepped mounting bracket is bolted to an extruded cement board. In order to prevent the stepped mounting bracket from falling off due to the loosening, the stepped mounting bracket must be firmly bolted. Therefore, when the stepped mounting bracket is overtightened to a predetermined value or more, there is a drawback that cracks are generated in the extruded cement board.

  In addition, the end face of the extruded cement plate that abuts the through-angle needs to be chamfered according to the through-angle, and in particular, this chamfering generates dust, which has the disadvantage of harming the health of the operator. there were.

  In order to eliminate the above-mentioned drawbacks, the present applicant has proposed a novel wall panel mounting apparatus in which a through angle is clamped and fixed between a backing plate and a stepped mounting bracket lower part (Japanese Patent Application No. 2005-33939). Unpublished.). According to this wall panel mounting device, welding of the stepped mounting bracket is not required, and the workability (working efficiency) is remarkably improved by omitting repair (rust prevention treatment) of the welded portion. However, when a stepped mounting bracket or the like is tightened with a bolt, for example, the stepped mounting bracket and the contact plate may be displaced from each other, leading to a decrease in construction efficiency. In particular, since the stepped mounting bracket and the contact plate must be held and held by hand so that they are not displaced from each other, the bolting operation cannot be performed with one hand.

  Therefore, the above-described welding and chamfering processes can be made unnecessary, and a technical problem to be solved in order to improve the construction efficiency by facilitating the bolt tightening work of the stepped mounting bracket or the like arises. It aims at solving this subject.

  The present invention has been proposed in order to achieve the above-mentioned object. A hollow wall panel such as an extruded cement plate is attached to a through angle fixed to a beam of a building by a stepped mounting bracket and a contact plate. A wall panel mounting apparatus for mounting, wherein a protrusion or a fitting hole is provided on one end side portion of the stepped mounting bracket, and the fitting hole or the protrusion fitted into the protrusion or the fitting hole is the Formed on the backing plate, and the corresponding plate is disposed in contact with the wall panel with the one end side portion of the stepped mounting bracket superposed on the outer surface thereof, and the corresponding plate and the stepped mounting bracket The through angle is configured to be inserted between the end side portion, and the stepped portion is formed by fastening the overlapping portion of the contact plate and the one end side portion of the stepped mounting bracket to the wall panel with a bolt. Between the other end of the mounting bracket and the backing plate The through-angle to provide a wall panel mounting apparatus comprising configured to secure clamping.

  According to this configuration, by appropriately placing the plate in contact with the wall panel and fitting the protrusion into the fitting hole, the plate and the stepped mounting bracket are overlapped so as not to be displaced from each other, and Correspondingly, the vertical part of the through angle is inserted between the other end of the plate and the stepped mounting bracket.

  Thereafter, the overlapping portion between the abutting plate and one end side portion of the stepped mounting bracket is fastened and fixed to the wall panel with a bolt. As a result, the through angle is elastically pressed against the abutting plate at the other end of the stepped mounting bracket, so that the through angle is sandwiched between the plate and the other end of the stepped mounting bracket by a spring action. It is attached and fixed. Further, when the overlapped portion is fastened with a bolt, the displacement between the fitting with the fitting step and the contact plate is effectively suppressed by the fitting action between the projection and the fitting hole.

  In the present invention, since the through angle is sandwiched and fixed between the contact plate and the stepped mounting bracket, welding of the stepped mounting bracket and chamfering of the wall panel become unnecessary.

  Also, when tightening the overlapping part of the contact plate and the stepped mounting bracket with bolts, the stepped mounting bracket and the contact plate are not displaced from each other, so it is necessary to hold the hand against the stepped mounting bracket etc. Thus, the bolt tightening operation can be easily performed with one hand, and the construction efficiency of the wall panel is remarkably improved as compared with the conventional case.

  The present invention is fixed to a beam of a building for the purpose of eliminating the above-mentioned welding and chamfering processing, eliminating the displacement of a stepped mounting bracket, etc., facilitating bolt tightening work and improving construction efficiency. A wall panel mounting apparatus for mounting a hollow wall panel such as an extruded cement board to a through angle with a stepped mounting bracket and a contact plate, and a protrusion or a fitting hole in one end side portion of the stepped mounting bracket And a fitting hole or projection that fits into the projection or fitting hole is formed in the backing plate, and the corresponding plate overlaps one end side portion of the stepped mounting bracket on its outer surface. And is configured so that the through angle is inserted between the corresponding plate and the other end portion of the stepped mounting bracket. Weight with one end of bracket By fastened to the wall panel portions with bolts, it was realized by configuring the through angle to secure clamping between the other end portion and the backing plate of the step with the mounting bracket.

  A preferred embodiment of the present invention will be described below with reference to FIGS. In FIG. 1, reference numerals 1 and 2 denote upper and lower extruded cement plates as hollow wall panels, respectively. Inside the extruded cement plates 1 and 2, a plurality of hollow portions are arranged in the vertical direction. Is formed. A plurality of these extruded cement plates 1 and 2 are arranged adjacent to each other in the vertical direction and the horizontal direction, thereby forming a vertical panel structure on the outer wall of the building.

  As shown in FIGS. 2 and 3, a sealing material 4, a refractory material 5, and the like are interposed at appropriate positions adjacent to each other in the vertical and horizontal directions between the extruded cement plates 1 and 2. The upper-stage extruded cement board 1 is placed and fixed on the lower-stage extruded cement board 2 through a horizontal through angle 6 made of a long base steel material.

  The through-angle 6 is formed in an L-shaped cross section, and has a horizontal portion 6a that is a panel weight receiving portion, and a vertical portion 6b that is suspended from one side end of the horizontal portion 6a. Further, as shown in FIG. 2, the vertical portion 6 b of the through angle 6 that supports the extruded cement board 1 is connected to the upper surface of the H-shaped steel beam 7 fixed to the floor slab via the piece angle 8. It is fixed.

  The extruded cement board 1 is connected and fixed to a through angle 6 by a wall panel mounting device 9. As shown in FIG. 4, the wall panel mounting device 9 is superposed on a stepped mounting bracket 10 that contacts the outer surface of the vertical portion 6 b of the through angle 6, and an upper portion of the back of the stepped mounting bracket 10, and , A contact plate 11 that contacts the inner surface of the vertical portion 6 b of the through angle 6, a plate-like flat nut 12 disposed on the hollow portion side of the extrusion-molded cement plate 1, and a tightening screwed into the screw hole 12 A of the flat nut 12 And the bolt 14 for use. The bolt 14 fastens and fixes the overlapped portion of the stepped mounting bracket 10 and the contact plate 11 to the extruded cement plate 1.

  As shown in FIGS. 5 and 6, the stepped mounting bracket 10 has an inclined step 15 at the middle in the vertical direction, and the upper vertical portion is located at the upper end side and the lower end side of the inclined step 15, respectively. 16 and the lower vertical part 17 are connected. As shown in FIG. 7, the upper vertical portion 16 is formed with a bolt through long hole 18 extending in the vertical direction. Further, as shown in FIGS. 8A to 8C, protrusions 19 are formed on both sides in the left-right width direction W of the stepped mounting bracket 10, respectively.

  Further, as shown in FIG. 9A, substantially U-shaped notches 20 and 20 are respectively formed on the left and right sides of the intermediate portion in the vertical direction of the contact plate 11, and the upper portion 21 of the plate 11 correspondingly. In the central part of this, a bolt penetration long hole 26 extending in the vertical direction is formed. Further, projections (rising portions) 23 and 23 are provided on both sides in the left-right width direction W of the upper portion 21 of the backing plate 11, respectively, and the stepped portions 23 and 23 are provided with the steps as shown in FIG. The protrusions 19 on both sides of the mounting bracket 10 are attached.

  Further, a bulging portion 24 is provided at the central portion of the lower portion 22 of the lower portion 22 in the left-right width direction, and the bulging portion 24 extends in the vertical direction orthogonal to the through angle 6. The cross-sectional shape of the bulging portion 24 is formed to be curved in an arc shape, and the vertical portion 6b of the through angle 6 is in line contact with the arc-shaped curved portion of the bulging portion 24. They are in contact (see FIG. 7).

  Furthermore, projecting pieces 25, 25 are provided on the lower edge portions of the notches 20, 20 of the backing plate 11, and the projecting pieces 25, 25, as shown in FIGS. 9 (a) to 9 (d), It is formed by bending at a right angle on the stepped mounting bracket 10 side. The slanted stepped portion 15 on the side of the stepped mounting bracket 10 is brought into contact with the projecting pieces 25 and 25, so that the rotation of the contact plate 11 is restricted, and the protrusions 23 and 23 are fitted to the stepped mounting bracket 10. Thus, the movement of the entire stepped mounting bracket 10 is restricted.

  In particular, in this embodiment, a circular protrusion 13 is provided in the vicinity of the upper side of the bolt through-hole 18 on the back of the stepped mounting bracket 10 as shown in FIGS. Yes. Further, as shown in FIG. 9 (a), a fitting hole 26A is opened at the center in the left-right width direction W of the contact plate 11 corresponding to the protrusion 13, and the fitting hole 26A is formed in this embodiment. Then, it is continuously formed at the upper end of the bolt penetration long hole 26 of the backing plate 11. Further, the fitting hole 26A has an arc portion corresponding to the protrusion 13, and the protrusion 13 on the stepped mounting bracket 10 side is detachably fitted into the fitting hole 26A. In the illustrated example, the fitting hole 26 </ b> A is formed continuously with the bolt penetration long hole 26, but should not be limited to this.

  Thus, when the projection 13 on the stepped mounting bracket 10 side is fitted into the fitting hole 26A on the backing plate 11 side, the stepped mounting bracket 10 and the backing plate 11 are automatically positioned and fixed to each other. And the relative positional shift of both is prevented. The length of the protrusion 13 of the stepped mounting bracket 10 is formed slightly smaller than the depth of the fitting hole 26A, that is, the plate thickness of the contact plate 11.

  Next, a construction example when the extruded cement board 1 is built in the through angle 6 will be described with reference to FIGS. It is assumed that the extruded cement plate 1 is disposed above the through angle 6 and a bolt penetration hole 27 is previously opened at a predetermined position of the extruded cement plate 1.

  First, as shown in FIG. 10, a backing plate 11 is arranged in the vertical direction (longitudinal direction) on the outside of the extruded cement plate 1, and the plate 11 is pressed against the outer surface of the extruded cement plate 1. Further, a flat nut 12 is pressed against the extruded cement plate 1 and set on the inner surface of the hollow portion of the extruded cement plate 1. Then, the stepped mounting bracket 10 is disposed and mounted on the upper portion of the backing plate 11. In this case, in this embodiment, the clip 10 is mounted in the horizontal direction (lateral direction), but of course it is not limited to this.

  Next, the bolts 14 are sequentially inserted into the long holes 18 of the stepped mounting bracket 10 and the long holes 26 (see FIG. 5) of the abutting plate 11, and the bolts 14 are screwed into the screw holes 12A of the flat nut 12. Then, as shown in FIG. 11, the attachment device 9 is temporarily fixed to the extruded cement board 1. Thereafter, the upper extruded cement plate 1 is gradually lowered to the lower extruded cement plate 2 side so that the upper extruded cement plate 1 is placed on the horizontal portion 6a of the angle 6 through the upper extruded cement plate 1; The abutting plate 11 is passed through and set in a state of being in contact with the vertical portion 6 b of the angle 6.

  Then, the stepped mounting bracket 10 is rotated 90 degrees downward and disposed in the vertical direction (downward), and a space between the lower vertical portion 17 of the stepped mounting bracket 10 and the bulging portion 24 of the backing plate 11 is provided. After inserting the vertical portion 6b of the through angle 6 into S, the bolt 14 is rotated and tightened to a predetermined position. In this case, since the protrusion 13 on the stepped mounting bracket 10 side is fitted into the fitting hole 26A on the backing plate 11 side, the upper portion of the backing plate 11 and the upper portion of the stepped mounting bracket 10 are mutually overlapped. Thus, the stepped mounting bracket 10 is automatically positioned and fixed with respect to the contact plate 11.

  Thereby, as shown in FIG.12 and FIG.13, the superposition | polymerization part of the upper part of the stepped attachment metal fitting 10 and the upper part of the contact plate 11 is fastened and fixed to the extrusion-molded cement board 1. FIG. In this case, when the overlapped portion of the stepped mounting bracket 10 and the contact plate 11 is tightened with the bolt 14, as shown in FIG. 14 (a), the vertical portion of the through angle 6 from the lower vertical portion 17 of the stepped mounting bracket 10 is provided. An elastic pressure contact force (spring force) F corresponding to the magnitude of the bolt fastening force acts toward 6a.

  For this reason, the vertical portion 6 b of the through angle 6 is firmly pressed against the bulging portion 24 side of the contact plate 11 by the pressure contact force of the lower vertical portion 17 of the stepped mounting bracket 10. FIG. 14B shows a state after the extrusion cement board 1 is attached by the attachment device 9. As shown in the figure, the extrusion cement board 1 is firmly attached while being in surface contact with the contact plate 11.

  That is, the through-angle 6 is strongly clamped and connected by the bulging portion 24 of the contact plate 11 and the lower vertical portion 17 of the stepped mounting bracket 10. In addition, when attaching the lower extrusion cement board 2 with the said attachment apparatus 9, it can construct similarly to the above by arrange | positioning the attachment apparatus 9 below the through angle 6 (refer FIG. 2).

  In this way, the through angle 6 is connected and fixed between the stepped mounting bracket 10 and the contact plate 11 with a required clamping force, and therefore it is not necessary to weld the through angle 6. In addition, the extruded cement plate 1 can be securely fixed by the spring force of the lower vertical portion 17 of the stepped mounting bracket 10 without strongly tightening the stepped mounting bracket 10 with the bolt 14. There is no risk of cracks occurring in the extruded cement board 1 due to the tightening force. Further, the end surface of the extruded cement board 1 that contacts the through angle 6 does not need to be chamfered to match the through angle 6.

  In this embodiment, just by fitting the protrusion 13 of the stepped mounting bracket 10 into the fitting hole 26A of the backing plate 11, the positioning fixing of the stepped mounting bracket 10 with respect to the plate 11 is automatically performed. The extrusion-molded cement board 1 can be easily built, and the construction efficiency is remarkably improved. In particular, when the overlapping portion of the contact plate 11 and the stepped mounting bracket 10 is tightened with the bolt 14, the stepped mounting bracket 10 and the contact plate 11 are displaced from each other due to the fitting effect of the protrusion 13 and the fitting hole 26A. There is no fear. Thus, since it is not necessary to press the stepped mounting bracket 10 and the contact plate 11 with a hand so as not to be displaced, the bolt 14 can be tightened easily and quickly with one hand.

  In the above embodiment, one circular protrusion 13 and one fitting hole 26A are formed at the center in the left-right width direction on the upper part of the rear surface of the stepped mounting bracket 10. However, the number and position of the protrusions 13 and the like are not particularly limited. Should not be limited to. For example, the shape of the protrusion 13 or the like may be a square or the like. The number of the protrusions 13 may be plural, and when the number of the protrusions 13 is an even number, it can be provided on both sides of the stepped mounting bracket 10 in the left-right width direction.

  15 to 17 show another embodiment of the present invention, which is different from the above embodiment in that the stepped mounting bracket 10 and the contact plate 11 are disposed upside down. To do. That is, as shown in FIG. 15, the lower vertical portion 6 b of the through-angle (underlying steel material) 6 is inserted between the pad plate 11 and the upper portion of the stepped mounting bracket 10, so The lower superposed portion is fastened and fixed to the extrusion-molded cement board 1 with bolts 14, and at the same time, the through angle 6 is pressed by the spring force generated at the upper part of the stepped mounting bracket 10 with this fastening force, The through-angle 6 is sandwiched and fixed between the abutting plate 11 and the upper portion of the stepped mounting bracket 10. In addition, the same code | symbol is attached | subjected to the member same as the said Example.

  As shown in FIG. 16, a fitting hole 26 </ b> A is provided at the center of the lower end of the bolt penetration long hole 26 in the contact plate 11, and the protrusion 13 that fits into the fitting hole 26 </ b> A has a stepped mounting bracket. 10 is provided directly under the bolt through long hole 18.

  According to this configuration, when the extrusion-molded cement plate 1 is attached to the angle 6 through fitting the protrusion 13 on the stepped mounting bracket 10 side into the fitting hole 26A on the contact plate 11 side, The stepped mounting brackets 10 are superposed so that they are not displaced from each other, are temporarily fixed by bolts 14 and fixed, and the contact plate 11 is placed in contact with the outer surface of the extruded cement plate 1 in this state. The vertical portion 6 b of the through-angle 6 is inserted between the upper part of the contact plate 11 and the stepped mounting bracket 10.

  Thereafter, the overlapping portion of the backing plate 11 and the stepped mounting bracket 10 is finally tightened with the bolts 14, whereby the backing plate 11 and the stepped mounting bracket 10 are fastened and fixed to the extruded cement plate 1. At this time, as shown in FIG. 17, due to the tightening force of the bolt 14, an elastic spring force F is generated in the upper portion 17 of the stepped mounting bracket 10, and a pressing force (clamping force) is applied to the through angle 6. ) Acts, the through angle 6 is firmly clamped and fixed between the bulging portion 24 of the backing plate 11 and the upper portion 17 of the stepped mounting bracket 10.

  Thereby, the welding of the stepped mounting bracket 10 and the chamfering process of the extrusion-molded cement plate 1 become unnecessary. In addition, since the stepped mounting bracket 10 and the contact plate 11 can be prevented from being displaced from each other simply by fitting the protrusion 13 into the fitting hole 26A, the work of installing the extruded cement board 1 is very difficult. It becomes easy and construction efficiency improves remarkably compared with the past.

  In particular, when tightening the overlapped portion of the backing plate 11 and the stepped mounting bracket 10 with the bolt 14, the stepped mounting bracket 10 and the backing plate 11 are not displaced from each other, so that the bolt 14 can be tightened easily and quickly with one hand. Can be done.

  It should be noted that the present invention can be variously modified without departing from the spirit of the present invention, and the present invention naturally extends to the modified ones. For example, unlike the above embodiment, it is possible to provide a fitting hole on the side of the stepped mounting bracket and to form a protrusion that fits into the fitting hole on the contact plate.

  In the present invention, the form or structure of the fitting hole and the fitting hole is not particularly limited, and in short, the base plate and the stepped mounting bracket are walled by tightening the overlapping portion of the base plate and the stepped mounting bracket with a bolt. The panel is fastened to the panel. At this time, the bolt is tightened to apply an elastic pressure contact force (spring force) to the angle through the stepped mounting bracket. Anything sandwiched and fixed between them is included in the technical scope of the present invention. Moreover, in the said Example, although applied to what forms a vertical panel structure using a wall panel, this invention is applicable also to what forms a horizontal panel structure using a wall panel.
