Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a building having an outer wall such as tile, mortar, concrete, or ceramic siding, which has cracks or molds due to aging including freeze-thawing, alkali reaction of aggregate, and salt damage. When repairing an outer wall that is severely contaminated with a material such as the above, the old outer wall material is used as a base without breaking it, and on top of that, metal siding material, metal plate, heat insulation panel, ALC plate, PC board, ceramic siding material, tile The present invention relates to a structure for draining outer wall materials for implementing new outer wall materials such as.

[0002]

2. Description of the Related Art The outer wall of this type of building is weathered, corroded, and cracked in a few years due to wind, rain, vibration, pollution, etc., which damages the appearance of the building and causes a dangerous situation such as peeling off of the outer wall material. It is necessary to take measures such as newly replacing the outer wall material. In this refurbishment, without destroying and removing the old outer wall material, or after peeling off a part or all of the damaged surface, it is covered with the old outer wall material through the support metal fittings fixed to the outer wall material. A new method for replacing a new outer wall material such as a curtain wall or a spandrel to be worn is becoming popular.

[0003]

As an example of the conventional construction method,
Japanese Examined Patent Publication No. 60-1466 discloses that a new outer wall material is attached to an old uppermost wood portion of a building where a new outer wall material is attached so as to cover the entire surface of the upper wood portion and the uppermost end of the new outer wall material. A building that has been renovated by water-tightly connecting and is introduced. Further, Japanese Patent Laid-Open No. 6-136929 proposes a draining structure with a cover sheet and a cover plate that engage with each other in a U-shape between outer wall members as lateral joints when forming the outer wall. Further, a caulking agent has been planted on both ends of a dry type outer wall material.

However, when attaching a new headstock to the old headstock, in order to water-tightly bond the new outer wall material, the top end of the outer wall material must be covered so as to protrude into the recess of the new headstock. Therefore, the upper structural part is forced to protrude from the lower structural part, and the outer wall material cannot be attached to the flat surface, which impairs the appearance.
Although it can be expected to have a draining effect, it has a problem in productivity due to the complicated structure of the cover material and the siding plate. Rainwater may be stored inside due to the caulking agent.

[0005]

In order to eliminate such a problem, the present invention fixes a supporting metal member on the surface of an outer wall material of an existing building without basically destroying and removing the outer wall material of the existing building, In the outer wall material repair work for covering and spreading the new outer wall material over the existing outer wall material through the support metal fittings, when the new outer wall material is mounted as a horizontal joint member using the caulking agent, the shape of the new outer wall covers the caulking agent. As described above, the present invention proposes a draining structure of an outer wall material which has an upper end portion and a lower end portion which are inclined downward toward the outside and which is excellent in drainage property.

[0006]

According to the present invention, the shape of metal siding, tile, etc. as a new outer wall material is formed and processed so as to cover the caulking agent of the horizontal joint member, so that the caulking agent is not directly exposed to the weather. , Even if rainwater enters, the upper and lower ends of the new outer wall material that joins before being stored in the caulking agent have a downward slope toward the outside, so rainwater is discharged along this slope. . Outer wall material can be attached to the flat without projecting from the upper part to the lower part of the building, so it is also aesthetically pleasing. Also, the molding and processing of the new outer wall material itself is not complicated,
It is possible to provide a draining structure for an outer wall material which is excellent in productivity and workability. As the caulking agent, a commercially available caulking agent suitable for each type may be applied as it is.
