Description

TECHNICAL FIELD The present invention relates to a large-scale building material to be installed on a wall surface of a building or the like.

(Prior art and its problems) Conventionally, when building an outer wall surface of a building or the like on a tile surface, a large-sized PC plate is often installed in a row along the wall surface of the building or the like. As shown in FIG. 5, a plurality of tiles 52, 52 are lined up on the front surface side in a state in which a joint M is formed, and the back surface side of each tile 52 is concrete 53.
Integrated into a single plate,
For example, tiles 5 are provided on the bottom side of the wooden frame 54 as shown in FIG.
2, 52 are arranged in a row, a temporary joint 55 is interposed between the tiles 52, and a pin 56 is driven in a connecting shape between the tiles 52, and a metal fitting 57 (also in the case of a wire or the like is attached to the pin 56. The concrete 53 is cast by placing concrete 53 from the upper surface side.
After the solidification, the wooden frame 54 and the temporary joint 55 are removed to complete the work.

However, in the prior art, since the pins 56 are arranged between the tiles 52, it is difficult to dispose the temporary joint 55 at the portion where the pins 56 are present, the provisional condition of the temporary joint 55 is deteriorated, and the beautiful joint M There was a problem that it was difficult to model.

(Means for Solving the Problem) The present invention has been devised in view of the above-mentioned conventional problems, and an object thereof is to provide a large-sized building material having a large strength in which aesthetic joints are favorably formed, The gist is a large building material that is molded by placing concrete on the back side of each tile with a temporary joint material interposed between the tiles. An engagement hole is provided, a pin insertion hole orthogonal to this engagement hole is formed from the side surface side of each tile, and a pin is embedded in the pin insertion hole, and the pin is formed at the tip of the metal fitting. The fitting is fixed in the engagement hole by penetrating the fitting, and the fitting is embedded in the concrete to be cast, and the pin fitting hole is filled with the concrete to be molded, Is.

(Operation) In the engagement hole provided in each tile, a metal fitting is fixed via a pin, and concrete is placed on the back side of each tile in a state where the metal fitting is fixed. The metal fittings fixed in place are embedded in the concrete to be cast, and the strength of the joint between each tile and the concrete is strengthened by the metal fittings, resulting in a large-scale building material with a strong structure. or,
Since the pins that fix the metal fittings are driven in from the side of each tile in an embedded manner, the pins do not project to the side of each tile, and the temporary joint material is satisfactorily interposed without being disturbed by the pins. A large building material can be molded in this state, and by removing the joint material during demolding, it is possible to obtain a large building material with beautiful joints formed on the surface side.

(Example) Hereinafter, the Example of this invention is described based on drawing.

FIG. 1 is a perspective view of the main part of the back side of a tile attached to the front side of a large building material. Each tile 1 has engagement holes 1a formed from the back side near the four corners on the back side. In this engagement hole 1a, an L rod-shaped metal fitting 22 is provided from the back side.
It is possible to insert the tip of
Further, a pin fitting hole 1b is formed in each of the engaging holes 1a at right angles from the side surface side of the tile 1, and the pin fitting hole 1b is formed.
When the pin 3 is driven into the inside from the side, the engaging hole 1a is formed.
The pin 3 is inserted into the pin hole 2a at the tip of the metal fitting 2 that is engaged in the inside.
Will penetrate, and the metal fitting 2 will be fixed to the back surface side of the tile 1 by the pin 3 in an upright state. The engaging hole 1a and the pin fitting hole 1b of each tile 1 can be formed in advance when the tile 1 is formed, and in the state in which the metal fitting 2 is fixed to each tile 1 via the pin 3, as shown in FIG. As described above, a plurality of tiles 1 are arranged on the bottom surface side of the wooden frame 54, and a joint forming material 55 is interposed between the tiles 1 and 1. In this state, the wooden frame 5
4, the concrete 4 is cast from the upper side, the wooden frame 54 is demolded after the concrete 4 is solidified, and the temporary joint material 55 is removed at that time, so that the cross section is enlarged as shown in FIG. With the metal fittings 2, 2 embedded in the concrete 4, the concrete 4 and the back side of each tile 1 are firmly integrated with each other via the metal fitting 2, and the tile 1 is stronger than the concrete 4 without peeling off. A large building material K having a structure can be obtained.

Further, since the pins 3 and 3 are embedded in the side surface side of each tile 1, the pins 3 and 3 do not project from the side surface side of each tile 1, and there is no space between the tiles 1 and 1. Since the temporary joint material 55 can be satisfactorily interposed, when the temporary joint material 55 is removed later, the joint M having the aesthetic appearance formed by the temporary joint material 55 is formed between the tiles 1 and 1. That is, the aesthetic appearance of the surface side is significantly improved. Further, since the pin fitting hole 1b is filled with the concrete 4 to be placed, it is not exposed, and
There is no need to worry about pin 3 coming off.

It should be noted that the metal fitting 2 may be changed to, for example, a plate-like one as shown in FIG. 4, and in FIG. 4, the metal piece 2 has an arc shape on the back side of the tile 11 corresponding to the arc shape of the lower end portion of the metal fitting 12. Engagement holes 11a, 11a having a cross section are formed, and each of the engagement holes 11a has a pin fitting hole 11b which is orthogonal from the side.
Is formed, and the pin 3 is inserted from the side surface side in the state where the lower end of the metal fitting 12 is inserted into the engagement hole 11a.
The metal fitting 12 can be firmly fixed to the back surface side of the tile 11 via the pin 3 by driving into the b. In this fixed state, as shown in FIG. 2 described above, the concrete 4 can be placed on the back surface side in the wooden frame 54 to favorably form a large building material.

Further, in the present invention, the metal fittings 2 or 12 are fixed in advance on the back surface side of each tile 1 or 11 with the pin 3 interposed therebetween, and the tiles 1 or 11 are arranged in the wooden frame 54, and concrete 4 is cast into the molding. Therefore, the work of arranging tiles in a row in a wooden frame and then inserting a pin or the like as in the related art becomes unnecessary, and the workability becomes extremely good. Further, since each pin 3 is embedded in the side surface side of each tile 1, it does not protrude laterally, and the temporary joint material 55 can be favorably arranged between the tiles. By 55, the joint M on the front surface side of the completed large-scale building material K has an extremely neat appearance and the aesthetic appearance is improved.

(Effects of the Invention) The large building material of the present invention is a large building material that is molded by placing concrete on the back side of each tile in a state in which a temporary joint material is interposed between the tiles, An engaging hole for mounting a metal fitting is provided on the rear surface side of the tile, a pin inserting hole orthogonal to the engaging hole is formed from the side surface side of each tile, and a pin is embedded in the pin inserting hole to embed the pin. The metal fitting is fixed in the engagement hole by penetrating into the pin hole formed at the tip of the metal fitting, the metal fitting is embedded in the concrete to be cast, and the pin fitting hole is driven. By burying with the concrete and molding, the joint strength between the concrete and the tile can be increased, and a large-sized building material having a strong structure can be obtained, and the molding work can be extremely facilitated and workability can be improved.

Further, since the provision of the temporary joint material is improved at the time of modeling, beautiful joints are formed on the surface side of the large-sized building material after modeling, and the appearance on the surface side after completion is significantly improved.
