Description

[Detailed description of the invention] [Industrial field of application] This invention relates to a waterproof structure for the joints of exterior materials, and more specifically, for example, for waterproofing between exterior materials attached to the outside of a building frame such as siding or curtain wall. This relates to improvements in waterproof structures that seal and waterproof joints.

[Prior Art] Generally, in this type of waterproof structure, a structure is known in which a receiving frame material is fixed to the joint between exterior materials on the outer surface of a building frame, and a batten is attached to this receiving frame material with sealing properties. ing. As shown in FIG. 9, the conventional batten used in this waterproof structure has waterproof fins c, c...
A type with multiple protruding strips is used. In this case, the fins c, c, . . . are attached to the hard batten base a by adhesive, or are simultaneously formed on the batten base a by extrusion molding.

[Problems to be solved by the invention] However, the former, that is, the hard joint base a
In the case where the fins c, c, etc. are glued to the joint insertion part b, the installation work of the fins c, c, etc. is not only complicated but also requires a lot of manufacturing man-hours. There is a risk that the bonded portions with c, c, etc. may peel off, and there is a problem that there is concern about waterproofness. In addition, in the latter case, that is, in the case where the batten board base a, the joint insertion part b, and the fins c, c, etc. are integrally formed, there is no problem of peeling,
During molding, a pre-formed aluminum profile is passed through a die and plastic is welded to its surface, so extrusion can damage the aluminum profile, and this damage can impair its appearance. Moreover, there are problems such as increased costs. As a means to solve these problems, it may be possible to interpose a sealing material between the receiving frame material fixed to the joint part of the exterior material on the outer surface of the building frame and the batten that engages with this receiving frame material. With this structure, there is a problem that alignment of the sealing material during construction is troublesome and construction efficiency is poor.

[Means for solving the problem] This invention was made in view of the above circumstances, and as a means to solve the above technical problem, a waterproof structure is provided in which the receiving frame material and the batten are engaged with each other by interposing a sealing material. In the above, a waterproof structure for the exterior joint portion is provided, which is characterized by facilitating the alignment of the sealing material, ensuring the engagement between the receiving frame material and the batten, and improving the sealing performance. This is what we are trying to provide.

In other words, this invention includes a pair of locking portions that are fixed to exterior material joints on the outer surface of the building frame and protrude outward, and a support portion that extends outward from the tip of each locking portion. a receiving frame material having: a batten having a pair of locking legs projecting from the inner surface of the base that can be engaged with a locking portion of the receiving frame material; and a batten interposed between the receiving frame material and the batten and the exterior covering. an elastic sealing material that can come into contact with the edge of the material, and the elastic sealing material is sandwiched between the supporting part of the receiving frame material and the base of the batten and also comes into contact with the edge of the exterior material. An exterior material joint comprising a pair of seal parts and a temporary connection part that connects these seal parts to each other and is separated from the seal parts when the receiving frame material and battens are engaged. The aim is to provide a waterproof structure.

In this invention, the batten may be of any type as long as it has locking legs and engages with the receiving frame material, but preferably the width of the base is made larger than the width of the receiving frame material. It is better to do so.

Further, the sealing material is separated when the receiving frame material and the batten are engaged, and the sealing portion is sandwiched between the supporting part of the receiving frame material and the batten base of the batten, and the edge of the exterior material. It is preferable that the temporary connection part of the sealing material is made of a plate-shaped base piece and a pair of upright pieces that stand on both sides of this plate-shaped base piece. It is preferable that the sealing part has an inclined part connected to the tip of each upright piece at the inner end of the sealing part, and a thick-walled exterior material abutting part is formed at the outer end of the sealing part. It is preferable that a separation notch be formed at the connecting portion between the sealing portion of the sealing material and the temporary connecting portion.

[Effect] The above technical means works as follows.

After installing the elastic sealing material so as to make contact with the supporting part of the receiving frame material fixed to the joint part of the exterior material, when the batten is pressed from the outside toward the receiving frame material, the locking part of the receiving frame material and the batten The sealing part of the sealing material and the temporary connecting part are separated between the locking legs of the frame member and the batten, and the receiving frame material and the batten are engaged, and the elastic material sandwiched between the support part of the receiving frame material and the batten base is Due to the repulsive force of the sealing material, the receiving frame material and the batten are firmly engaged, and the joint portion of the exterior material is waterproofed.
