Description

  The present invention relates to a tile fall prevention metal fitting for preventing a tile covering a surface of a building from falling.

  A plurality of tiles juxtaposed as exterior and interior materials are attached to the outer wall of the building and the inner wall of the tunnel. Tiles are used for the purpose of protecting the surface of a building and decorating the surface. However, the tile may be peeled off due to deterioration of the adhesive that is attached to the wall surface, or the tile may be damaged due to a collision with flying objects. When tiles fall on the ground, if broken pieces of tiles are scattered on the ground, it is extremely dangerous for nearby passersby.

  There are also cases where tiles that are difficult to deform are not able to follow the deformation of buildings due to large vibrations such as earthquakes and fall off. For this reason, a method is considered in which the tile and the building are moved separately from each other through the metal fittings, instead of bringing the tile into close contact with the building. As described in Patent Document 1, an invention of a fall prevention structure that holds a tile or its surroundings so that it does not easily fall even if damage occurs is disclosed.

Components having the same function are denoted by the same reference numerals, and repeated description thereof may be omitted. Note that the vertical direction is the vertical direction, the horizontal direction is the left-right direction, the normal direction is the front-rear direction, and the outer surface side of the wall is the front side, and the inner surface side of the wall is the back side. Further, the upper, lower, left, and right side surfaces of the tile are expressed as an upper side, a lower side (bottom side), a left side, and a right side (side side) from the shape of the tile.

  First, the tile fall prevention metal fitting which is this invention is demonstrated. 1A is a plan view, FIG. 1B is a front view, and FIG. 1C is a right side view showing a wall surface using a tile fall prevention metal fitting. Wall surfaces include ECP (extruded cement board), ALC (lightweight aerated concrete cured with high temperature and high pressure steam), RC (steel reinforced concrete), etc. good.

  As shown in FIG. 1, in the present embodiment, when the wall surface 100 is a cement hollow plate 100a, a case where a triangular tile 110 is attached to the surface will be described. For example, a tile 110 having a right isosceles triangle shape obtained by rotating a square 45 degrees and cutting it up and down is used.

  The cement hollow plate 100a is an ECP molded in a predetermined size, and a plurality of the cement hollow plates 100a are arranged in a single wall shape. ECP is a mixture of cement, siliceous raw material, fibrous raw material, etc., extruded to form a hollow portion between the front and back plates, and cured into an autoclave to form a panel. is there.

  The tile 110 is a plate material such as porcelain or ceramic that is attached to the surface thereof in order to protect or decorate the cement hollow plate 100a. A plurality of tiles 110 having a predetermined shape are juxtaposed, and joints 112 for absorbing deformation and the like are opened between the tiles 110, and the joints 112 are filled with a sealing material or the like. Note that the tiles 110 may all have the same shape, or may have different shapes. However, it is assumed that there is a shape with a pointed lower end such as a downward triangle.

  In the example of FIG. 1, tiles 110 of right isosceles triangles of the same size are used, but different upward triangles are arranged on the upper, lower, left and right sides of one downward triangle, and similarly, the upper, lower, left and right sides of one upward triangle are arranged. All the tiles 110 are aligned by disposing different downward triangles in each.

  The tile 110 is attached to the cement hollow plate 100a through a tile drop prevention fitting. Examples of the tile fall prevention metal fitting include a support metal fitting 200, a corner metal fitting 300, and a bottom metal fitting 300a. Instead of directly attaching the tile 110 to the cement hollow plate 100a, the support metal fitting 200 is disposed on the cement hollow plate 100a, and the tile 110 is supported by the square metal fitting 300 or the bottom metal fitting 300a. The corner receiving metal fitting 300 or the bottom receiving metal fitting 300a is supported so as to be received on the lower side of the tile 110, but may be received by being hung in a groove or the like formed on the back surface of the tile 110.

The lower side support includes a lower left side support 311 that is bent obliquely at the lower left side and a lower right side support 312 that is bent obliquely at the lower right side. Note that the lower left side receptacle 311 and the lower right side receptacle 312 do not reach the lower end, and the lower end is left open.

  Similarly, the upper corner pad 320 has an upper side support that protrudes toward the tile 111 (front side) so as to abut on the upper left side and the upper right side of another tile 111 with a sharp upper end. The upper side support includes an upper left side support 321 that is bent obliquely at the upper left side and an upper right side support 322 that is bent obliquely at the upper right side. Note that the upper end may be vacant.

The connecting portion 330 is interposed between the lower corner pad 310 and the upper corner pad 320, and the upper corner pad 320 is coupled to the lower side of the lower corner pad 310. The hook 340 is provided on the upper side of the lower corner pad 310 so as to straddle the support fitting 200 backward. The hook 340 may be lightened by providing a notch 341.

  The upper part of the corner metal fitting 300 is hung on the support metal fitting 200 by the hook 340, but the lower part of the corner metal fitting 300 is in a state of being suspended from the cement hollow plate 100 a by the support metal fitting 200. Therefore, in order to stabilize the position in the front-rear direction, a bent piece 350 is provided by bending the lower side of the upper corner pad 320 and projecting it to the cement hollow plate 100a side (rear side).

As shown in FIG. 4, the bottom receiving metal 300 a includes a lower pad 360 for receiving the bottom side of another tile 111, a hook 370 for hanging on another support metal 201 disposed below the support metal 200 in parallel therewith, and the like. Have

  The lower pad 360 has a bottom receiver that is bent at the lower side and protrudes toward the tile 111 (front side) so as to abut the bottom of another tile 111 with a sharp upper end. The hook 370 is provided on the upper side of the lower pad 310 so as to straddle another support fitting 201 backward.

  5A is a plan view, FIG. 5B is a front view, and FIG. 5C is a right side view showing a part (upper part) of a corner bracket of the tile fall prevention metal fitting. FIGS. 6A and 6B are (a) a plan view, (b) a front view, and (c) a right side view showing a part (left part) of a corner bracket of the tile drop prevention bracket. A part of the corner receiving metal fitting 300 may be used in accordance with the shape of the tile 110 at the end of the cement hollow plate 100a connected in plural.

  As shown in FIG. 5, the corner bracket 300b is formed only in the upper half of the corner bracket 300 when another tile 111 does not exist below the tile 110 at the lower end of the cement hollow plate 100a. .

  In addition, as shown in FIG. 6, the corner bracket 300 c is only the left half of the corner bracket 300 when there is no other tile 111 on the right side of the tile 110 at the right end of the cement hollow plate 100 a. is there.

  FIG. 7A is a front view and FIG. 7B is a right side view showing a state in which a tile is held using a tile fall prevention metal fitting. In addition, the broken line in a front view shows the corner metal fitting 300 hidden behind the tile 110, and the alternate long and short dash line shows the support metal fitting 200 hidden behind the tile 110 and the corner metal fitting 300.

  As shown in FIG. 7, the support fitting 200 is fixed to the cement hollow plate 100 a by the fasteners 250, and the square receiving fitting 300 is hung on the support fitting 200. Then, the tile 110 is held by the corner bracket 300. The tile 110 and the cement hollow plate 100a are not in direct contact with each other by the corner receiving metal 300 and the support metal 200. That is, the tile 110 is held at a position away from the cement hollow plate 100a by a predetermined distance by the support metal fitting 200 and the corner metal fitting 300.

  The lower left side receptacle 311, the lower right side receptacle 312, the upper left side receptacle 321, and the upper right side receptacle 322 of the corner metal fitting 300 are arranged so as to be the joint 112 between the tiles 110. Then, the lower corner of one tile 110 is received by the lower left side receptacle 311 and the lower right side receptacle 312, and the upper corner of another tile 111 facing the lower side of the tile 110 is received by the upper left side receptacle 321 and the upper right side receptacle 322.

  Note that the lower left side receptacle 311 also receives the upper right side of other tiles adjacent to the left side of the one tile 110, and the lower right side receptacle 312 also receives the upper left side of other tiles adjacent to the right side of the one tile 110. The upper left side receptacle 321 also receives the lower right side of another tile adjacent to the left side of another tile 111, and the upper right side receptacle 322 receives the lower left side of another tile adjacent to the right side of the other tile 111.

  An adhesive is applied to the back surface of the tile 110. An elastic adhesive or the like is used as the adhesive, and is interposed between the tile 110 and the cement hollow plate 100a. The inclusion 120 may be put on the surface of the cement hollow plate 100a. Examples of the inclusion 120 include a turtle shell net and an insulating sheet. The tortoiseshell net is a metal net having a hexagonal mesh, and the adhesive 110 is entangled with the mesh to suppress the separation of the tile 110.

  Further, the insulating sheet is separated so that the cement hollow plate 100a that is easily deformed by vibration or the like and the tile 110 that is not easily deformed are not fixed. Although the cement hollow plate 100a improves the earthquake resistance by connecting a plurality of the cement hollow plates 100a, the connecting portion is likely to change, and the tile 110 may break without being able to cope with the change. Therefore, the tile 110 is not adhered to the cement hollow plate 100a by the insulating sheet, and the fluctuation of the cement hollow plate 100a is not transmitted to the tile 110.

  The tiles may be spread on the wall surface by arranging polygons with corners facing down or in combination with other shapes. As the shape of the tile, if the shape is a regular shape such as a regular triangle, a square, a rhombus, or a regular hexagon, gaps other than joints are unlikely to occur. FIG. 8 is a (a) plan view, (b) front view, and (c) right side view showing a wall surface using a tile fall prevention metal fitting.

  As shown in FIG. 8, in the present embodiment, when the wall surface 100 is reinforced concrete 100b, a case where a regular triangular tile 110a is attached to the surface will be described. Different upward regular triangles may be arranged on the upper, lower, left and right sides of one downward regular triangle, and similarly, different downward regular triangles may be arranged on the upper, lower, left and right sides of one upward regular triangle.

  Reinforced concrete 100b is a material in which the reinforcing bar is passed through the concrete so that it is strong against compression and tension, and has improved earthquake resistance. A single wall is formed by placing concrete around the assembled rebar. In the case of the reinforced concrete 100b, a turtle shell net may be used as the inclusion 120, but an insulating sheet is unnecessary because a plurality of panels are not connected.

  As a tile fall prevention metal fitting for attaching the tile 110a to the reinforced concrete 100b, the support metal fitting 200 and the square metal fitting 300d are used. The support metal fitting 200 is disposed on the reinforced concrete 100b, and the tile 110a is supported by the corner metal fitting 300d hung on the support metal fitting 200. Note that the corner bracket 300d has the functions of the corner bracket 300 and the bottom bracket 300a.

  FIG. 9A is a plan view, FIG. 9B is a front view, and FIG. 9C is a right side view showing a corner receiving bracket of the tile drop prevention bracket. As shown in FIG. 9, the corner bracket 300d has a corner pad 380 for receiving the tile 110a, a hook 388 for hanging on the support bracket 200, a bent piece 389 for placing the lower end on the reinforced concrete 100b, and the like.

  The square pad 380 has a lower left side receiver 381 and a lower right side receiver 382 for receiving one tile 110a, and an upper left side receiver 383 and an upper right side receiver 384 for receiving another tile 111a below the tile 110a. It has a left base 385 for receiving other tiles adjacent to the left side, and a right base 386 for receiving other tiles adjacent to the right side of the tile 110a.

  Note that the lower left side receptacle 381 also receives the upper right side of other tiles adjacent to the left side of the one tile 110a, and the lower right side receptacle 382 also receives the upper left side of other tiles adjacent to the right side of the one tile 110a. The upper left side receptacle 383 also receives the lower right side of another tile adjacent to the left side of another tile 111a, and the upper right side receptacle 384 also receives the lower left side of another tile adjacent to the right side of the other tile 111a. Furthermore, the left bottom side receptacle 385 also receives the upper side of another tile adjacent to the left side of another tile 111a, and the right bottom side receptacle 386 also receives the upper side of another tile adjacent to the right side of another tile 111a.

  The square pad 380 is provided by opening a rectangular cutout hole 387 in the square bracket 300d. However, one side of the four sides is not cut out, and the one side is bent and raised to project to the tile 110a side (front side).

  The hook 388 is provided on the upper side of the square pad 380 so as to straddle the support fitting 200 backward. Further, the bent piece 389 is bent at the lower side of the corner receiving metal fitting 300d and is protruded to the reinforced concrete 100b side (rear side) in order to stabilize the position in the front-rear direction.

  In this way, even a tile with a sharp upper end or lower end can be held so as not to fall off the wall surface. Since the side near the tip is supported instead of the pointed tip of the tile, it can be avoided that the tip hits and is chipped.

  As mentioned above, although the Example of this invention was described, it is not limited to these. For example, even if the tile does not have a regular shape such as an equilateral triangle, the square bracket may be formed according to the shape of the lower end of the tile.
