眼とする工法に関するものである。Description: TECHNICAL FIELD The present invention relates to a case where an exterior material such as a building is partially peeled from a base skeleton over a period of time, and the peeling spreads and the exterior material falls off. The present invention relates to a construction method whose main purpose is repair to prevent such problems.
従来の技術 一般に、建築物等の外装材（モルタル、タイル貼り、テ
ラゾ、木板、石板等）は下地躯体に一体的に接着固定し
て設けるべきものであるが、建築完成後、または久しい
間に部分的に剥離することが多い。このように下地躯体
とその外装材とが剥離しておるのをその侭放置すると、
剥離が波及進展して外装材が下地躯体から離脱落下する
に至り危険極まりない。Conventional technology Generally, exterior materials for buildings (mortar, tiled, terrazzo, wood board, stone board, etc.) should be integrally bonded and fixed to the base frame, but after construction is complete or long time ago. It often peels off partially. In this way, when the base frame and its exterior material are separated,
Peeling spreads and the exterior material comes off from the base structure and falls, which is extremely dangerous.
従来、この外装材の部分的剥離に対しては接着剤または
モルタルを間隙部に注入充填して剥離間隙を埋めると同
時に外装材を下地躯体に接着しておった。Conventionally, for partial peeling of the exterior material, an adhesive or mortar is injected and filled in the gap portion to fill the separation gap, and at the same time, the exterior material is adhered to the base skeleton.
ところが、上記従来工法では剥離間隙内に接着材または
モルタルを注入すると、その充填側圧のため外装材が外
方に膨れ、接着力が不充分になるのみならず作業中に全
面的剥離を誘起することとなり危険である。However, in the above conventional method, when the adhesive or mortar is injected into the peeling gap, the outer side material swells outward due to the pressure on the filling side, not only the adhesive force becomes insufficient but also the whole peeling is induced during the work. It is very dangerous.
そこで、従来の接着固定工法の欠点を除去するため、本
発明出願人は特許第742439号（特公昭48-39044号公報参

如き接着固定工法を開発している。Therefore, in order to eliminate the disadvantages of the conventional adhesive fixing method, the applicant of the present invention has made the adhesive such as Japanese Patent No. 742439 (see Japanese Patent Publication No. 48-39044) and Japanese Patent No. 890757 (see Japanese Patent Publication No. 52-15891). We are developing a fixed construction method.

入接着を行う場合に比較し、補修時剥離個所に全く無理
な外力を作用させることなく外装材を下地躯体に固定さ
せることができるようになった。In the former method, the exterior material is partially peeled from the base structure, and the adhesive of appropriate viscosity is injected by punching from the surface of the exterior structure and the exterior material is temporarily fixed to the base structure by point bonding. After that, the main injection bonding is performed. As described above, since the outer injection material is temporarily fixed to the base frame by point bonding and then the main injection bonding is performed, a completely unreasonable external force is applied to the peeling point at the time of repair as compared with the case where the direct main injection bonding is performed. It is now possible to fix the exterior material to the base structure without any need.

このパイプ連結により補修箇所に多量の接着剤を充填す

させることができるようになった。Further, in the latter method, a pipe is vertically inserted between the exterior material and the base structure, where the exterior material is partially separated from the base structure, and the pipe is bonded and fixed to the base structure and the exterior structure. The two are connected by pipes.
With this pipe connection, it is not necessary to fill a large amount of adhesive in the repaired area, and it is possible to fix the exterior material to the base frame with a small amount of adhesive.

ができない。Problems to be Solved by the Invention However, since these methods require a long time to cure the adhesive by point bonding and pipe connection, the adhesive is not attached after the work of temporarily fixing the exterior material to the base frame is completed. Since the main injection bonding cannot be performed for a long time until it hardens, the work efficiency is extremely poor. In addition, when the exterior material is largely lifted from the base skeleton and is peeled off, the support material is pressure-bonded to the base skeleton to perform the adhesion work, so it is necessary to cure for a long time until the adhesive is cured. I can't remove it.
そこで、この発明は外装材を下地躯体に短時間で接着固
定する工法を提供することを目的とするものである。Therefore, an object of the present invention is to provide a method for adhering and fixing an exterior material to a base frame in a short time.

In the second invention, the bar material is alternately inserted in the diagonally different directions over the exterior material and the base frame, and the exterior material and the base frame are partially separated from the base frame in the second invention. By alternately inserting the rods in different diagonal directions, temporarily fixing the exterior material to the base skeleton with the rods, and then performing the main injection bonding, the third invention partially peels from the base skeleton. On both sides of the crack generated in the exterior material, a bar material is inserted in an obliquely separating direction across the exterior material and the base structure. In the fourth invention, the exterior material is partially enlarged from the base structure. The outer material is pressed against the base frame by pressing the lifted and separated part with a support, and the bar material is alternately inserted into the part in the diagonally different direction across the outer material and the base structure.
