Description

  The present invention relates to a metal fitting for fixing a tile locking member without making a hole more than necessary in an extruded cement board having a hollow portion.

  For finishing the walls of buildings, etc., wet methods that directly attach tiles and stones to the base using mortar, or hook the tiles and stones on the locking members fixed to the base and stick them with elastic adhesive There are dry methods. As the base, a precast concrete (PC) board, a lightweight aerated concrete (ALC) board cured with high temperature and high pressure steam, an extruded cement board (ECP), etc. are juxtaposed in the plane direction.

  PC boards are often used as outer wall materials for high-rise buildings due to their strength. PC boards include, for example, PC-laden tile panels in which tiles and the like are cast together with concrete in a factory and are known as a construction method that causes extremely few accidents due to separation of tiles and the like.

  In addition, a dry construction method in which hardware (tile locking member) is fixed and applied on site, a hardware joint bonding method, etc. are adopted as a construction method for safely holding tiles and the like. Since the PC board has reinforcing bars inside, it is possible to fix the hardware for safely tensioning the tiles with anchors or screws. Become high.

  On the other hand, ALC plates and extrusion-molded cement plates are starting to be widely used as base plates for tiles and the like because of their light weight and surface strength. The ALC plate has a reinforcing bar or the like as a reinforcing material inside, but the extrusion-molded cement plate intermittently penetrates the hollow portion in the vertical direction to reduce the weight.

  Extruded cement board is lighter than PC board and has fire resistance, and it moves following the deformation of the building due to vibrations such as earthquakes, so it absorbs vibrations and suppresses falling off of tiles etc. It is difficult to paste tiles or the like across the space, and the tiles are often limited to those allocated in the board.

  As described in Patent Document 1, an invention of a mounting structure for an extruded cement board in which a metal part is provided in a hollow portion is also disclosed. Further, as described in Patent Document 2, an invention of a functional panel mounting structure in which a mounting member is provided on a hollow protrusion is also disclosed. In addition, in order to attach a fixing bracket or the like for locking a tile or the like to the extruded cement board, a metal receiving part (attachment bracket) in a hollow portion is used.

  However, the extrusion-molded cement board has a very high compressive strength in the vertical direction, but the bending strength in the front-rear direction is weak, so there are many holes to provide a metal fitting (attachment fitting) in the hollow part of the extrusion-molded cement board. If it is vacated, the bending strength is greatly reduced, and there is a possibility that the extruded cement board is broken by cracks or the like. In addition, if another hole or the like is made at a position other than the metal fitting (mounting bracket) to fix a fixing bracket or the like for locking the tile or the like, the bending strength further decreases.

  As in the inventions described in Cited Document 1 and Cited Document 2, there are cases in which the hollow portion is shaped to increase the strength, or a metal fitting for attaching the fixing bracket is built in the factory in advance. Depending on the case, there may be an increase in the number of defects due to the holes, leading to a decrease in strength.

  In addition, there is also a thing that suppresses to the minimum defect part against wind pressure etc. by welding the fixing bracket to the beam etc. in the frame structure so that the load of finishing material such as tiles is not applied to the extruded cement board However, the shear strength varies depending on the construction method, and the strength is insufficient because the load is applied only by welding.

  Then, an object of this invention is to provide the metal fitting for fixing a tile latching member, without making a hole more than necessary to the extrusion-molded cement board which has a hollow part.

  In order to solve the above-described problems, the present invention provides a metal fitting for fixing a tile locking member attached to the front surface of a base plate in which a plurality of hollow portions penetrating vertically are provided, along the front surface of the base plate In order to arrange the tile locking member having a bottom portion attached in a vertical direction, a vertical portion extending forward from a side end of the bottom portion, and an edge portion bent sideward from the vertical portion.

It has the edge part 430 bent so that it might face each other from the standing part 420 and the vertical part 420 to the side.

  The load receiving frame 400 is provided with an edge 430 parallel to the bottom portion 410 by bending the plate material so as to have a height corresponding to the vertical portion 420 from the bottom portion 410. The bottom 410 is in contact with the extruded cement board 110, and the edge 430 is partly in contact with the tile locking member 130.

  The bottom portion 410 is sandwiched between the front surface of the extruded cement board 110 and the hanging portion 330 of the support metal 300 at the top. That is, the hanging portion 320 of the support fitting 300 is continuously provided so as to straddle from the insertion portion 310 to the front of the bottom portion 410 of the load receiving frame 400, and the hanging portion 330 of the support fitting 300 extends along the bottom portion 410. It should be extended from.

  The vertical portion 420 is provided so that the height thereof is the distance between the extruded cement board 110 and the tile locking member 130. Therefore, the bent piece 340 of the support fitting 300 may be provided continuously from the hanging part 330 within the height of the hanging part 420 along the hanging part 420. Further, a through groove 440 is formed in the vertical portion 420 at a position where the clasp 500 is passed.

  The vertical portion 420 may be a left vertical portion 420 a at the left end of the bottom portion 410 and a right vertical portion 420 b at the right end of the bottom portion 410. The edge portion 430 may be a left edge portion 430a extending leftward from the left suspending portion 420a and a right edge portion 430b extending rightward from the right suspending portion 420b. Further, the through groove 440 may be a left through groove 440a formed in the left vertical part 420a and a right through groove 440b formed in the right vertical part 420b.

  As shown in FIG. 7, the clasp 500 is fitted to the through groove 440 and the through groove 440 through the through plate 510 for passing through the through groove 440 opened in the vertical portion 420 of the load receiving frame 400, and the through plate 510. A concave portion 520 is provided in the gutter plate 510 so as to be hooked in a notch 350 provided in the bent piece 340 of the support fitting 300.

  The saddle plate 510 is passed from the left through groove 440a of the load receiving frame 400 to the right through groove 440b. And the gutter 510 is passed from the left notch 350a of the support fitting 300 to the right notch 350b. At this time, the vacant positions of the left through groove 440a and the left notch 350a are matched, and the vacant positions of the right through groove 440b and the right notch 350b are matched.

  The recess 520 is engaged with the through groove 440 of the load receiving frame 400 and the notch 350 of the support fitting 300, thereby locking the load receiving frame 400 to the support fitting 300. Therefore, the recess 520 may have a length from the left vertical portion 420a to the right vertical portion 420b. Further, since the hook plate 510 is only required to be locked, the vertical portion 420 of the load receiving frame 400 only needs to be high enough to pass the plate 510.

  Next, the attachment of the fixture for the tile locking member according to the present invention will be described. FIG. 8 is a perspective view showing a situation in which the support fitting of the fixing metal fixture of the tile locking member is attached to the extruded cement board, and FIG. 9 is a perspective view showing a situation in which the load receiving frame is attached to the extruded cement board. FIG. 10 is a perspective view showing a state in which the clasp is attached to the extruded cement board.

  As shown in FIG. 8, when the insertion portion 310 of the support fitting 300 is fitted into the hollow portion 120 from above the extrusion molded cement plate 110, the hook portion 320 of the support fitting 300 becomes the upper surface of the front plate of the extrusion cement plate 110. As a result, the hanging part 330 of the support fitting 300 comes to the front surface of the extruded cement board 110.

  As shown in FIG. 9, when the load receiving frame 400 is arranged on the front surface of the extruded cement plate 110, the upper portion of the load receiving frame 400 is supported from below the support fitting 300, and the bottom portion 410 supports the front surface of the extruded cement plate 110. The metal fitting 300 is inserted so as to be sandwiched between the hanging portions 330.

  Since the bent piece 340 of the support metal fitting 300 is along the inside of the vertical portion 420 of the load receiving frame 400, the load is set so that the notch 350 of the bent piece 340 and the through groove 440 of the vertical portion 420 are aligned. The position of the receiving frame 400 is adjusted.

  As shown in FIG. 10, the saddle plate 510 of the clasp 500 is passed through the through groove 440 of the vertical portion 420 and the notch 350 of the bent piece 340, and the concave portion 520 of the clasp 500 is passed through the notch 350 of the bent piece 340. The load receiving frame 400 is locked to the support fitting 300 so that the load receiving frame 400 does not come off.

  Since the lower part of the load receiving frame 400 is not fastened and the arrangement is not stable, the load receiving frame 400 may be fastened using a hole formed in the extruded cement board 110 with a minimum necessary defect. The load of the tile locking member 130 and the tile 140 applied to the load receiving frame 400 is received on the upper surface of the extruded cement board 110 by the support fitting 300, and the burden on the front surface of the extruded cement board 110 is reduced.

  In this way, it is possible to provide the fixing bracket 200 for fixing the tile locking member 130 without making more holes than necessary in the extruded cement plate 110 having the hollow portion 120. The fixing bracket 200 is fitted into the hollow portion 120, and a stable strength is maintained by receiving a load of a tile panel or the like locked to the tile locking member 130 on the upper surface of the extruded cement board 110 having a high compressive strength. can do.

  Moreover, the strength reduction by a crack etc. can be prevented by suppressing the defect | deletion part by making a hole in the extrusion-molded cement board 110 to the minimum. Furthermore, since the fixing bracket 200 is attached to the extruded cement board 110, it is possible to follow the deformation of each board.

  Since the fixing metal 200 is not connected by bolts and nuts, but is locked in a hook shape, the fixed cement 200 is not affected by the heights of the bolts and nuts, and the extrusion-molded cement board 110 and the tile panel, etc. The distance from the tile locking member 130 that locks can be minimized.

  As mentioned above, although the Example of this invention was described, it is not limited to these. For example, the fixing bracket 200 may be attached with the load receiving frame 400 after the support fitting 300 is attached, or may be attached with the support fitting 300 after the load receiving frame 400 is attached.
