Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a sealing structure between housing units, and more particularly to a structure for sealing a joint cross portion formed at an intersection of a vertical joint and a horizontal joint between units.

[0002]

2. Description of the Related Art In the unit construction method, as shown in FIG.
A joint cross portion 3 where a horizontal joint and a vertical joint intersect is formed at a portion where the upper, lower, left and right units 1a, 1b, 1c and 1d are adjacent to each other. At the joint cross section, unit tolerances, installation errors, etc. are likely to appear, and the gap size is unlikely to be constant. In other words, those errors are absorbed and removed at this joint cross section. On the other hand, since the joint cloth portion also serves as an opening for communicating the outside with the inside of the room, high water stopping performance is required. Conventionally, the above-mentioned error is likely to appear,
In the joint cloth portion 3 which requires waterproofness, a wet type seal structure in which a caulking material is filled in a house construction site is generally adopted. In the sealing structure using caulking material, as shown in FIG.
A masking tape (not shown) is attached to the edges of a, 5b, 5c and 5d, the joint cloth part 3 is leveled while being filled with the caulking material 7, and the masking tape is removed.
The caulking material 7 was hardened and the joint cloth portion 3 was closed after a predetermined curing period.

[0003]

However, in the conventional sealing structure using the caulking material 7, a skillful technique is required for smoothing the caulking material 7 so that the caulking material 7 looks good, and complicated preparation work using a masking tape or the like is required. It was necessary and the workability was poor. After the caulking material 7 is filled, a curing period is required until the caulking material 7 is cured, which is an obstacle to shortening the construction period. In addition, there is a problem that dust and the like are apt to adhere to the caulking material 7 before the curing and the construction quality is deteriorated. Furthermore,
With the sealing structure using the caulking material 7, peeling may occur when an external force is applied, and this is particularly noticeable at the joint cross portion 3 where errors are concentrated, so it is difficult to carry out in-plant construction before shipping the unit. It was. The present invention has been made in view of the above circumstances, and provides a seal structure between housing units that can easily close a joint cross portion where an error is likely to occur with high water shutoff, and can be installed in a factory. Therefore, the purpose is to improve the workability, waterproofness, and productivity.

[0004]

A seal structure between housing units according to the present invention for achieving the above object is a joint cross portion formed by intersecting a horizontal joint (31) and a vertical joint (33).
