Description

[Detailed Description of the Invention] [Industrial field of application] The present invention is a joint for a building that has earthquake resistance, and has the functions of improving the resistance to side pressure when placing concrete, as well as increasing the soundproofing and sound insulating properties. Material equipment.

[Conventional technology]

Conventionally, this kind of seismic joint material device has been used in Japanese Utility Model Sho 63-15.
As described in Japanese Patent No. 488, by inserting and supporting a flat plate-like relatively elastic partition member formed to have a constant thickness, with respect to a pair of joint members arranged inside and outside the wall portion so as to face each other. A form in which the wall portion is cut off is disclosed.

[Problems to be solved by the device]

In the above-mentioned conventional method and means, when the partition material is mounted in the wall frame and partitioned in an edge shape, the partition material does not have sufficient proof stress against the side pressure at the time of placing concrete, so that it is deformed or comes off from the joint substrate. However, there is a serious drawback in that an accurate slit wall cannot be constructed.

Further, since the partition material is a flat plate and partitions the inside of the wall linearly, there is a problem in that it lacks soundproofing and sound insulation and is unreasonable in practical use.

[Means for Solving the Problems]

The present invention has been made in view of the above conventional problems, and an object thereof is to provide earthquake resistance and to have sufficient resistance to side pressure at the time of placing concrete, and to improve soundproofing and sound insulation. An object is to provide a jointing material device for buildings that is extremely effective in practice.

As a means for this, a supporting piece is provided with a required space along the back part of the joint board arranged inside and outside the wall of the building, and curved in an arc shape with respect to the supporting piece of each joint board. It is characterized in that both ends of a molded partition member are fitted and the wall of a building is partitioned into an edge shape.

[Action]

According to the above structure, the joint substrate is attached so as to face the inner and outer molds of the wall, and after supporting both ends of the partition member formed by curving in an arc shape on the supporting pieces of the pair of joint substrates, the wall is attached. By pouring concrete from the outer surface direction of the curved partition member in the mold, sufficient yield strength against side pressure can be obtained and a reliable slit wall can be obtained.

Further, since the inside of the wall is not straight but is divided into arcs to cut the edges, the soundproofing and sound insulating properties are improved, and the problems of the conventional example are solved.

〔Example〕

Next, an embodiment of the present invention will be described in detail with reference to the drawings.

FIG. 1 is a cross-sectional view of a wall body using the first embodiment of the present invention, showing a case where a jointing material device is installed at the wall side.

In the figure, 1 is a long joint substrate made of synthetic resin,
A recessed joint groove 1a is provided in the front part, and the left and right side wall surfaces are extended to the back side to project anchor pieces 1b, 1c, and a required space a is provided along the inside of the anchors 1b, 1c. The support piece 1d is provided so as to project.

1e represents a soft synthetic resin layer formed on the outer surface of the joint substrate 1.

Reference numeral 2 is a partition member such as a foamed Ekylene body in which a hard synthetic resin plate 2a is formed on the outer surface, and is formed by being curved in an arc shape.

Next, an example of use of the jointing material device for buildings according to the first embodiment of the present invention will be described.

As shown in FIG. 1, in a suitable position of the wall forms P1 and P2 near the edge of the pillar, the joint substrate 1.1 is arranged with respect to the inner form P1 and the outer form P2 of the wall, and the anchor pieces 1b and Drive nails N and N from 1c and attach to the wall formwork.

For this nailing, joint board 1.1 Support piece 1 on the back
It is also possible to fix it from the inner center of d.

Subsequently, the partition member 2 is supported by inserting its curved outer surface in the column direction into both ends of the joint substrate 1.1 between the support pieces 1d at the back, and then placing concrete from the column side to form a wall Concrete is also placed in the frame to cure it.

After dismantling the wall formwork P1, P2, the nails N, N can be processed by cutting or breaking.

Next, another embodiment of the joint material device of the present invention will be described.

FIG. 2 is a cross-sectional view of the essential parts showing the second embodiment.

In the form of the joint material device of the second embodiment, a joint groove 21a having a recessed shape is formed in the front portion of the joint substrate 21, and support pieces 21d, 21d are provided so as to project along the back portion with a required space a. Ordinary joint material having anchor pieces 21b, 21b projecting on both left and right side walls is used, and the partition member 22 is curved and formed in an arc shape. Both ends of the joint member are horizontally bent. It is inserted into and supported by the support pieces 21d, 21d on the back of the substrate 21.

In the case of the second embodiment as well, it is used in the same manner as in the first embodiment, and the same effect as that of the first embodiment is obtained.

In each of the above-described embodiments, the form in which the recessed joint groove is provided on the front surface of the joint substrate 1.21 is shown and described.
Not limited to this embodiment, it is easily conceivable to use a joint substrate having a flat front surface.

[Effect of device]

As described in detail above, according to the jointing material for a building of the present invention, a partition formed by curving the casting direction of concrete into an arc shape is compared to a partitioning material having a flat plate-like partitioning material as in the conventional example. By performing from the outside of the material, it is possible to obtain sufficient yield strength against the lateral pressure of concrete,
A reliable and accurate slit wall is constructed, which has the effect of obtaining a highly reliable seismic structure.

In addition, compared with the conventional example in which the edge is cut with a flat partition material, the wall is partitioned in an arc shape, so sound from inside and outside the building does not pass straight through the wall, which results in sound insulation and sound insulation. It is possible to obtain a jointing material device for buildings which is improved, rational, and extremely effective in practice.
