Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial Application Field) The present invention relates to a dry construction structure for building materials such as large tiles, and more particularly to a construction structure for fixing building materials to a building frame surface via fixing tools and supports.

(Issues to be Solved by the Prior Art and Inventions) As a construction structure for pasting and fixing relatively large building materials such as tiles on one surface, the construction structure shown in FIGS. 7 and 8 has conventionally been used. Among them, the one shown in FIG.
06 are connected, and the lower end surfaces of the building materials 108 in the L tier are supported by this flat metal fitting 108, and the positioning pins 11 are common to the pin holes previously provided in the building materials 108 in the upper and lower tiers.
0 is inserted to position the upper and lower building materials 108.

However, in the case of this construction structure, if the thickness of the building material 108 is thick, no particular problem will occur, but if the thickness of the building material 108 is thin, when the sealant 112 is packed between the upper and lower building materials 108, The metal 34106 and the positioning pin 110 get in the way, making it impossible to ensure a sufficient thickness for the sealing material 112, which causes the seal to break when the frame, building material 108, etc. expand or contract or change over time. There's a problem.

The construction structure shown in FIG. 8 was devised to solve this problem, and the upper branch, in which part of the pole 114 is embedded in the building material 108 of each upper and lower level, is prevented from falling out by a retaining pin 116.
For the lower building material 108, the downwardly bent piece 118 of the T-shaped metal fitting 117 fixed to the 1-shaped metal fitting 102 is brought into close contact with the back surface of the building material, and then fixed to the building material 108 with a 114° nut 124. , and the upper building material 1
Pol for 08) 114. The back hanger metal fitting 122 is fixed with a nut 124 and is engaged with the upwardly bent piece 120 of the T-shaped metal fitting, whereby the upper and lower building materials 10
8 is attached and fixed to the frame surface 104.

In this construction structure, unlike the construction structure shown in FIG. 7, there are no obstacles such as the flat metal fittings 1069 and positioning pins 110 between the upper building material 108 and the lower building material 108, so there is no possibility of seal breakage as described above. Although this problem does not occur, on the other hand, in the case of this construction structure, a retaining pin 116 as an attachment part for the building material 108 is required for each building material, and the retaining pin 11B is a pin formed on the building material 108 during construction. It is necessary to insert it into the hole and then fit it into the fitting hole provided in the hole 114, which makes the construction troublesome, complicates the structure, and increases the construction cost.

In addition, in this construction structure, it is necessary to drill holes in the building material 108, and since drilling the holes is a troublesome work, the cost of the building material increases.

(Means for Solving the Problem) The present invention has been made to solve the above problem, and its gist is to provide an insertion portion on the back side of the building material that extends in the thickness direction of the building material. A locking groove having an engaging portion expanding in a direction parallel to the back surface is provided at the tip of the insertion portion, and a fixing device such as a bolt having a large diameter head at the end is inserted into the locking structure. The building material is prevented from coming off by engaging the head with the engaging portion, and the building material is pasted and fixed to the surface of the structure by fixing the fixture to a support extending from the surface of the structure. There is a particular thing.

(Operation and Effects of the Invention) In the construction structure of the present invention, a fixing device such as a bolt is inserted into a locking groove on the back side of the building material, and the large diameter head is engaged with the engaging portion of the groove. By supporting such a fixture with a support, building materials can be attached and fixed to the frame surface.

As described above, in the case of the construction structure of the present invention, there is no need for parts to prevent fixing tools such as bolts from coming off, and there is no need for special work to prevent them from coming off. Can be easily attached to the body surface. This simplifies the construction work, simplifies the construction structure, and reduces construction costs.

In addition, with the construction structure of the present invention, there is no need to drill holes in the building material for inserting the retaining pin, so the cost of the building material itself is reduced, and the locking grooves on the back side of the building material can be cut in the four corners. It is possible to form the locking groove not only in the center but also in any other position, and if the locking groove is formed continuously over the entire width of the building material, the fixing location can be freely selected. Furthermore, even when a building material is cut into a desired size, it can be fixed on the frame surface without any problem.

(Example) Next, embodiments of the present invention will be described in detail based on the drawings.

In Fig. 2, 10 is a ceramic building material (thickness 16s + s) with a size of 60 (1 m + x 600 mm or more), and locking grooves #112 are formed at the four corners of the back side. As shown in , it consists of a straight insertion part 14 that extends inward in the thickness direction from the back surface of the building material, and an engagement part 16 that is formed continuously with the insertion part 14 .

The engaging portion 16 is of a shape that expands in a direction perpendicular to the thickness of the building material 1O, that is, in a direction parallel to the back surface of the building material, and the engaging portion 16 extends in a direction parallel to the back surface of the building material 10.
7.

Figure 1 shows how to use this locking groove 12 to attach the building material lO to the frame surface 1.
8 shows a specific example of pasting and fixing. In this figure, reference numeral 20 denotes a single-shaped metal fitting fixed to the body surface 18 with an anchor bolt 22, and this L-shaped metal fitting 20
The T-shaped fitting 24 is attached to the bolt 26. They are connected by a nut 28.

On the other hand, the shaft portion of the bolt 30 is inserted into the locking groove insertion portion 14 of the building material IO, and the large diameter head portion 32 at the tip thereof is engaged with the engaging portion 16. That is, the bolt 30 is prevented from coming off by the engagement between the head 32 and the engaging portion 16.

The building material 10 shown in the lower part of the figure is fixed with a bolt 30 and a nut 34 with its back surface in close contact with the downwardly bent piece 38 of the T-shaped metal fitting 24.
Also, in the upper building material lO, back banger metal fittings 3
6 is fixed by bolts 30 and nuts 34, and its back hanger fitting 36 is engaged and fixed to the upwardly bent piece 40 of the T-shaped fitting 24.

As described above, according to the construction structure of this example, the bolt 30 is inserted into the locking groove 12 of the building material lO, and the bolt 30 is inserted into the T-shaped metal fittings 24, 1.
The building material 10 can be pasted simply by connecting or engaging with the shaped metal fittings. This simplifies the construction work and simplifies the construction structure.

The locking groove 12 on the back surface of the building material can be formed, for example, by the method shown in FIG. 4.

In this figure, 48 is a frame mold, and 50 is an upper mold.

52 is a lower mold, 54 is a convex part, 56 is a stopper cylinder,
58 is a stopper block. As shown in FIG. 5, a rubber elastic body 60 is fixed to the upper end of the convex portion 54. As shown in FIG.

In the method of this example, first, with the upper mold 50 open, the lower mold 52 and the convex portion 54 are lowered by a predetermined amount to form a molding recess between the frame mold 48 and the lower mold 52. In this example, the amount of descent of the lower die 52 is greater than the amount of descent of the convex portion 54. The reason will be explained in detail later.

Next, as shown in (B), the raw material powder of the building material lO is filled into the molding recess, and then, as shown in (C), the stopper cylinder 56 is actuated to stop the pub lock 58.
is ejected, and then the upper mold 50 is lowered to compression mold the raw material powder. At this time, the frame 48 is pushed down by the frame drop block 51 to about 172 degrees of the original molding recess depth, that is, the flour insertion depth, and at the same time, the convex part 54 is brought into contact with the stopper block 5B by a lifting cylinder (not shown). lower to position. After the pressurizing process of the raw material powder is completed in this way, the frame mold 48 is first lowered or the upper mold 50 and the lower mold 52 are lowered.
, and when the upper mold 50 separates from the upper surface of the frame mold 4B, the stopper block 5 is lifted as shown in CD).
8 is retracted and the convex part 54 is lowered, and the convex part 54 is extracted from the molded body.Subsequently, the frame mold 48, the upper mold 50, and the lower mold 52 are moved relative to each other to separate the upper surface of the frame fi48 and the lower mold 52.
When the upper part of the mold 50 is flush with the upper side, the upper die 50 is released and the molded body is taken out by taking out the molded body.

A molded building material is obtained in this way, and during molding, the locking groove 12 is simultaneously molded by the convex mold @54. FIG. 5 specifically shows this situation. As shown in the figure, a rubber elastic body 60 is fixed at the upper end of the convex shape 1s54, so that the rubber elastic body 60 simultaneously pressurizes the raw material powder. Renal deformation in the direction perpendicular to the direction of pressure (see (B))
, whereby the engaging portion in the locking groove 12 is formed (
(See (C)).

In this example, as described above, the amount of descent of the lower die 52 and the convex part 54 is made different in step (B) of FIG.

This is to prevent a difference in compressibility of the powder between the part (A) where the locking groove 12 is formed and the other part (I+), as shown in FIG. 5(A). be. That is, for example, if we consider the case where the powder filling depth is 40ml1 and it is compressed to 20mm, and the locking groove 12 is formed at a depth of 10m5+ from the back surface, the convex part 54 is made to protrude by 10mm from the beginning. In this case, in the part (i), the raw material powder will be compressed to the powder insertion depth of 172, but in the part (a), the raw material powder will be compressed to 2/3, and the compressibility will change. Therefore, in this example, the convex portion 54 is initially made to protrude by 20 mm, the raw material powder is filled into the molding recess, and then the foam is pulled in to compress the raw material powder. That's how I do it. In this way, the compressibility of the powder becomes 1/2 in both the part (a) and the part (n), and the depth of the lock 1112 becomes toam.

Although the embodiments of the present invention have been described in detail above, the present invention can be configured and implemented in other forms and aspects.

For example, the locking groove 12 can be provided in the vertical direction as shown in FIG. A plurality of these can be formed intermittently, or they can be formed continuously in the vertical and horizontal directions. Alternatively, it is also possible to form them in a cross shape in the diagonal direction. When the locking grooves are formed continuously in this manner, there is an advantage that even when the building material is cut and used, there is no problem in fixing it to the frame surface.

In addition, it is possible to make the vertical and cross-sectional shapes of the locking groove other shapes, and the rubber material may be silicone rubber, urethane rubber, or other material as long as it has the ability to deform under pressure. The present invention can be configured with various modifications based on the knowledge of those skilled in the art without departing from the spirit thereof.
