Has been. Of these, in FIG. 6, the L-shaped metal fitting 102 is fixed to the body surface 104 by the anchor bolt 100, the flat metal fitting 106 is connected to the L-shaped metal fitting 102, and the upper metal fitting 106 is connected to the upper stage. While supporting the lower end surface of the building material 108, common positioning pins 110 are inserted into pin holes provided in the upper and lower building materials 108 in advance to position the upper and lower building materials 108.

However, in the case of this construction structure, when the building material 108 is thick, no particular trouble occurs, but
When the thickness of 108 is thin, when the sealing material 112 is packed between the upper and lower building materials 108, the metal fitting 106 and the positioning pin 110 interfere and the thickness of the sealing material 112 cannot be secured sufficiently,
Therefore, there is a problem that the body, the building material 108, etc. expand and contract, or the seal breaks when the material ages.

The construction structure shown in FIG. 7 was devised in order to solve this problem. The upper construction stopper pin 116 in which the bolt 114 is partially embedded in the upper and lower building materials 108 is used to prevent the construction material, and the lower building material. As for 108, the downward bent piece 118 of the T-shaped metal fitting 117 fixed to the L-shaped metal fitting 102 is fixed to the building material 108 with the bolt 114 and the nut 124 in a state of being closely attached to the back surface of the building material, and the upper building material. For 108, bolt 114, nut 124
The back hanger metal fitting 122 is fixed by this, and this is locked to the upward bending piece 120 of the T-shaped metal fitting, so that the building materials 108 in the upper and lower steps are attached and fixed to the body surface 104. .

In this construction structure, as in the construction structure shown in FIG. 6, there are no obstacles such as the flat plate-shaped metal fitting 106 and the positioning pin 110 between the upper building material 108 and the lower building material 108, so the seal breaks as described above. However, in the case of this construction structure, on the other hand, a retaining pin 116 as a mounting component of the building material 108 is required for each building material,
It is necessary to insert 6 into the pin hole formed in the building material 108 and then fit it into the fitting hole provided in the bolt 114, which makes the construction troublesome and the structure is complicated and the construction cost is high. turn into.

Further, in this construction structure, it is necessary to perform the boring process on the building material 108, and since the boring process is a troublesome work, the cost of the building material also increases.

(Means for Solving the Problem) The present invention has been made to solve such a problem, and the gist thereof is an insertion portion extending in the plate thickness direction of a building material and a tip of the insertion portion of the building material. A locking groove having a uniform cross-section having a back surface and an engaging portion extending in a parallel direction is provided so as to extend in the left-right direction along the back surface of the building material and open at left and right end surfaces of the building material. Insert a fixing tool such as a bolt having a large diameter head into the locking groove to engage the head with the engaging portion to prevent the head from coming off, while moving the support up and down with respect to the body surface. The building material is attached by adjusting its position, the connecting tool is connected to the supporting tool so that the position in the direction perpendicular to the body surface can be adjusted, and the connecting tool is fixed to the back surface of the building material by the fixing tool. Is attached to and fixed to the body surface.

(Operation and Effect of the Invention) In the construction structure of the present invention, a fixing tool such as a bolt is inserted into the locking groove on the back surface of the building material, and the head having a large diameter is engaged with the engaging portion of the groove to be removed. The building material can be attached and fixed to the body surface by stopping and fixing the back surface of the building material to the supporting tool attached to the body surface via the connecting tool by this fixing tool.

As described above, in the case of the construction structure of the present invention, it is not necessary to perform a part for preventing the fixing tool such as a bolt from coming off and an operation for preventing the fixing tool from coming off. Can be easily attached to the body surface. This simplifies the construction work, simplifies the construction structure, and reduces the construction cost.

Further, in the construction structure of the present invention, since the building material does not need to be drilled for inserting the retaining pin, the cost of the building material itself is low, and the locking grooves on the back surface are only at the four corners. Instead, it can be formed at any other position such as the central part, and if the locking groove is continuously formed over the entire width of the building material, the fixing point can be freely selected. Further, even when the building material is cut to a desired size, it can be fixed to the body surface without any trouble.

In addition, in the present invention, since the locking groove is opened at the left and right end surfaces of the building material, it is possible to insert a fixing tool such as a bolt into the locking groove through the opening of the end surface, and thus the fixing tool This has the advantage that the work of mounting in the locking groove is easy.

In the construction structure of the present invention, since the locking groove is formed in the left-right direction of the building material, by adjusting the fixing position of the fixing tool in the locking groove to the left and right, the gap between the left and right building materials and the building material It is possible to adjust the width of (longitudinal joint).

Further, by adjusting the fixed position of the connecting tool with respect to the supporting tool in the direction perpendicular to the body surface, it is possible to adjust the position of the building material in the same direction, that is, the entrance / exit adjustment. Further, the vertical position of the building material can be adjusted by adjusting the vertical position of the support tool with respect to the body surface.

That is, according to the present invention, it is possible to adjust the lateral position of the building material, the entrance / exit adjustment, and the vertical position adjustment, and it is possible to make the construction-applied surface of the building material in a good finished state.

(Example) Next, the Example of this invention is described in detail based on drawing.

In FIG. 2, 10 is a ceramic building material (thickness: 16 mm) with a size of 600 mm × 600 mm or more, and locking grooves are provided at the four corners of the back surface.
12 are formed. As shown in FIG. 3, the locking groove 12 includes a straight insertion portion 14 having a cross-sectional shape that faces inward in the plate thickness direction from the back surface of the building material, and an engagement portion 16 formed continuously with the insertion portion 14. It is made into a shape. The locking groove 12 is open at the left and right end surfaces of the building material 10. The engaging portion 16 is a building material 10
Has a locking surface 17 in a direction perpendicular to the plate thickness of, that is, in a direction parallel to the back surface of the building material.

FIG. 1 shows a specific example in which the building material 10 is attached and fixed to the body surface 18 by utilizing the locking groove 12. In this figure, 20
Is an L-shaped metal fitting as a support tool fixed to the body surface 18 by an anchor bolt 22 in an elongated hole 20a extending in the vertical direction. The L-shaped metal fitting 24 is L by the bolt 26 and the nut 28.
In the elongated hole 20b of the character-shaped metal fitting 20, the position perpendicular to the body surface 18 (incoming and outgoing direction) is adjustably connected.

On the other hand, the shaft portion of the bolt 30 is inserted into the engaging groove insertion portion 14 of the building material 10, and the large diameter head portion 32 at the tip thereof is engaged with the engagement portion 16. That is, the bolt 30 is prevented from coming off by the engaging action of the head portion 32 and the engaging portion 16.

In the lower building material 10 in the figure, the back surface of the building material 10 is fixed to the downwardly bent piece 38 of the T-shaped metal fitting 24 with the bolts 30 and the nuts 34, and the upper building material is also fixed. In 10, the back hanger metal fitting 36 is fixed by the bolt 30 and the nut 34, and the back hanger metal fitting 36 is fixed.
Is locked and fixed to the upward bending piece 40 of the T-shaped metal fitting 24.

Thus, according to the construction structure of this example, the bolt 30 is
Insert it into the locking groove 12 of T-shaped metal fitting 24, L-shaped metal fitting 20
The building material 10 can be attached by simply connecting or engaging with it. 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.

In this figure, 48 is a frame mold, 50 is an upper mold, 52 is a lower mold, 54 is a convex mold part, 56 is a stopper cylinder, and 58 is a stopper block. As shown in FIG. 5, a rubber elastic body 60 is fixedly provided on the upper end of the convex portion 54.

In the method of this example, first the upper mold 50 is opened and the lower mold is
52 and the convex mold 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 lower die 52 is moved more than the convex portion 54 is lowered. The reason will be described in detail later.

Next, as shown in (B), the raw material powder of the building material 10 is filled in the molding recess, and then the stopper cylinder 56 is operated to project the stopper block 58 as shown in (C). The mold 50 is lowered to compression-mold the raw material powder. At that time, the frame lowering block 51 pushes down the frame mold 48 to the depth of the original molding recess, that is, about 1/2 of the powder-pour depth. Lower to the position where it hits. After the pressurizing step of the raw material powder is completed in this manner, the frame die 48 is then lowered or the upper die 50 and the lower die 52 are raised, and the upper die 50
At a time point when is separated from the upper surface of the frame mold 48, as shown in (D), the stopper block 58 is retracted, the convex mold portion 54 is lowered, and the convex mold portion 54 is extracted from the molded body. Continued frame 48
When the upper mold 50 and the lower mold 52 are moved relative to each other so that the upper surface of the frame mold 48 and the upper surface of the lower mold 52 are flush with each other, the upper mold 50 is separated and the molded body is taken out by a take-out device.

In this way, a molded article of the building material is obtained, and during the molding, the locking groove 12 is simultaneously molded by the convex mold portion 54. FIG. 5 concretely shows the situation. As shown in the figure, since the rubber elastic body 60 is fixedly provided on the upper end of the convex portion 54, the rubber elastic body 60 is elastically deformed in the direction perpendicular to the pressing direction at the same time when the raw material powder is pressed ((B )), Whereby the engaging portion in the locking groove 12 is molded (see (C)).

In this example, as described above, the lower mold 52 and the convex mold portion 54 are made to have different descending amounts in the step (B) of FIG. As shown in FIG. 5 (A), this is to prevent a difference in powder compressibility between the portion (a) where the locking groove 12 is formed and the other portion (b). is there. That is, for example, considering a case where the powder insertion depth is 40 mm and this is compressed to 20 mm, and the locking groove 12 is formed 10 mm deep from the back surface, when the convex portion 54 is projected by 10 mm from the beginning. In the part (b), the raw material powder is compressed to 1/2 of the powder insertion depth, but in the part (a), the raw material powder is compressed to 2/3, and the compression rate is Will make a difference. Therefore, in this example, the convex portion 54 is initially projected by 20 mm, the raw material powder is filled in the molding recess, and then this is retracted by 10 mm so that the raw material powder is compressed under pressure. . In this way, the compressibility of the powder is halved in both (a) and (b) and the depth of the locking groove 12 is 10 mm.

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 modes.

For example, not only the four corners of the back surface of the building material but also the central portion and other appropriate places can be provided with locking grooves. Further, a plurality of locking grooves can be formed intermittently or continuously. is there. When the locking groove is continuously formed in this way, even when the building material is cut and used, there is an advantage that no trouble occurs when fixing the building material to the body surface.

In addition, the vertical and horizontal cross-sectional shapes of the locking groove can be changed to other shapes, and the material of the rubber is silicon rubber, urethane rubber or any other material having a deformability by pressure. The present invention can be configured in a form in which various modifications are made based on the knowledge of those skilled in the art without departing from the spirit of the present invention, such as the use of appropriate ones.
