Description

[Detailed explanation of the device] This device is designed to prevent bending of short columns during earthquakes by installing tiles in advance within the wall formwork in the tile pouring method, and by forming appropriate cross-section defects and edge cuts in the concrete wall. The present invention relates to a joint material device for construction that is intended to prevent.

Conventionally, in the tile driving method, there were no suitable means or materials for constructing slit walls, and in each case plywood or other materials were used as edge cutting materials, or joint bars were often inserted between the tiles. .

However, the former method has poor workability and lacks reliability when it is attached between wall forms in advance.

Furthermore, in the latter case, sufficient slit walls cannot be expected for new seismic design, and there are practical problems.

This invention was made to solve the conventional drawbacks and problems, and its structure will be explained next with reference to the drawings of the embodiment.

FIG. 1 is a perspective view of a part of a partition material support 1 and a part of a partition material 6, respectively.

A long partition material support 1 made of synthetic resin or aluminum has support pieces 3, 3 for forming a partition material introduction groove 2 on the back side along its longitudinal direction.
, there are concrete anchor pieces 4, 4 on the left and right sides.
are provided protrudingly from each other, and a convex portion 5 having a width suitable for the joint between the tiles is formed at the center of the front surface to form an integral structure. (The shapes and combinations of the support pieces 3, 3 and the concrete anchor pieces 4, 4 are not limited to those shown in the drawings.) The partition material 6 to be inserted into the partition material introduction groove 2 of the partition material support 1 is, for example, A main body 6a made of elastite, sponge, styrene foam, etc. is interposed in the center, and both left and right sides are formed with a curing material 6b such as a hard vinyl chloride board to a predetermined width and thickness, and a material similar to the partition material support 1 is formed. It is a long item.

Note that 7 in FIG. 2 indicates the partition material support 1.
8 is a holding piece for this headless nail 7, which may be formed to an arbitrary length along the partition material support 1. , it may be formed into a simple cylindrical shape.

The construction joint material device of this invention with the above structure temporarily places tiles C---on the inside of the external wall formwork P1 on the tile placement side via base material A and sheet material B, as shown in FIG. 3, for example. After stopping, tiles C, C
The partition material support 1 and the convex portion 5 on the front surface thereof are fitted along the joint portion C1 between them.

Then, the nail 7 held by the holding piece 8 from the back side of the convex part 5 is driven into the outer wall formwork P1 through the sheet material B and the base material A of the joint part c1, and then the partition material 6 is fixed. It can be fitted into the introduction groove 2 of the partition material support 1 and supported.

Further, another partition support D, which is arranged coaxially and independently along the inner surface of the inner wall formwork P2, with the left and right collar pieces d1, d1 is nailed N, A partition material 6 similar to that described above can be inserted and supported along the inside of the partition material introduction groove d2.

In this case, if the wall to be constructed is connected with a concrete effective cross section of 1/6 of one side of the columns or within 10 cm, as shown in the results shown in Figure 3, the wall to be constructed will maintain the specified width almost regardless of wall thickness variations. The desired joint can be achieved simply by placing the same partition material on both sides.

In addition, as for this partition material, as shown by the chain line in FIG.
It is also possible to easily completely edge a concrete wall by inserting a piece of partition material between each partition material introducing groove 2 and d2 of the partition material support D attached to the concrete wall.

Of course, when tiles are placed on both sides, partition material supports 1 as described above may be used on both sides.

Note that the partition material support 1 on the tile driving side
As for the fixing means, it is also possible to adhere the tile installation surface on the front side with adhesive.

In addition, when nailing the partition material support 1, by using headless nails as described above, the nails can be easily removed and disposed of during or after dismantling the wall formwork, and the reinforcement can be improved. If plastic nails are used, the surface can be easily finished by breaking them off and the rust prevention effect is great.

As mentioned above, according to this invention, it is possible to easily construct a slit wall using the tile pouring method, and it is also possible to install the joints between tiles reliably and easily, and post-processing is rational, etc., and has practical advantages. It is valid.
