Description

Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a sealing structure of a joint between outer wall panels of a house or the like.

[Conventional technology]

At the time of building a house, a frame unit is preliminarily formed at a factory from wood or lightweight steel frame, and an inner wall panel, an outer wall panel, a floor panel, etc. are assembled there, thereby manufacturing a house unit. The construction method of building a house by assembling is performed.

In such a construction method, if moisture such as rainwater enters from the outer wall, it may not only adversely affect the furniture and fittings in the house, but also cause corrosion of the framework itself, such as lightweight steel frame, and waterproof the wall. Attention has been paid to water resistance. In particular, since the outer wall panel is a part that is in direct contact with the outside air, many techniques have been disclosed with respect to the waterproof structure of the joint between the outer wall panels that occurs when the outer wall panel is assembled (for example, see Japanese Unexamined Patent Publication No. 63-27637, Japanese Utility Model Application Laid-Open No. 64-19703, etc.).

In the above prior art, as shown in FIG. 4, as a first step, an outer wall panel composed of a board 1 and a reinforcing frame 3 is bolted to a stud 2 attached to a structure (not shown) as shown in FIG. Then, as a second step, the sealing member 5 is inserted into the joint 4 between the outer wall panels at an assembly factory.

Further, as another known example of a waterproof structure between building members, a waterproof joint material in which a band-shaped waterproof portion and a cylindrical joint closing portion are integrally formed with a band-shaped mounting portion is fixed to the joint surface of the building member, There is also known a structure in which a joint waterproof portion is provided with a double waterproof function by a band-like waterproofing portion and a cylindrical joint closing portion by bringing the joints into pressure contact with each other (Japanese Utility Model Publication No. 58-14166).
No.).

[Problems to be solved by the invention]

The former of the above prior arts is effective as a means for sealing a joint between outer wall panels, but has some problems to be solved.

The first is that the process of assembling the outer wall panel and the process of assembling the sealing member are separate processes, so that it takes time to construct them and the workability is not always sufficient. The outer wall panel consisting of the outer wall board and the reinforcing frame is transported and assembled as it is until the stop member is assembled, so the corners and other tips come into contact with surrounding objects during that time, and cracks and breakage may occur. Third, the gasket as a sealing member is required because the seal is applied to the front and the edge of the board of the outer wall panel as shown in FIG. In the event that damage occurs due to any circumstances, moisture may immediately enter the interior of the structure from the joints and cause corrosion to the framework structure, the reinforcing frame, etc. to which the outer wall panels are attached. It, and the like.

Also, the latter one of the prior arts does not have the disadvantage that the step of assembling the sealing member as described above is a separate step, but the joint material is simply fixed near the corner of the building member. However, if the joint material is damaged for some reason, there is a risk that moisture will immediately enter the interior of the structure from the joint portion.

An object of the present invention is to solve the above-mentioned problems of the prior art, and to obtain a sealing structure of a joint portion between outer wall panels with a smaller number of steps than in the related art, and to simply provide a cut edge of an outer wall board Not only sealing, but also obtaining a sealing structure of the joints between the outer wall panels, which has a sealing effect on the part of the reinforcing frame attached to the board. Furthermore, transport and assembly of the outer wall panels It is a main object of the present invention to obtain a sealing structure of a joint portion between outer wall panels so as not to cause damage to a tip portion such as a corner portion of the outer wall panel at the time.

[Means for solving the problem]

In order to achieve the above object, the present invention provides a sealing structure for a joint portion between outer wall panels having an outer wall board and a reinforcing frame attached along the lip portion slightly inside the lip portion thereof. There, the first corresponding to the Kiguchi part
An elastic sealing member integrally molded with the sealing portion and the second sealing portion corresponding to the reinforcing frame is mounted in advance on the kiguchi portion and the reinforcing frame in close contact with each other, and the elastic sealing member is adjacent to the elastic sealing member. Developing and providing a sealing structure of a joint between outer wall panels, which is formed by the opposing first and second sealing portions of a corresponding elastic sealing member of the outer wall panel being in close contact with each other. I do.

The shape and material of the outer wall board and the reinforcing frame used in the present invention can be conventionally known ones as they are, and are not particularly limited. In addition, the shape and material of the elastic sealing member are not particularly limited. In particular, the shape is such that each sealing portion of the sealing member mounted on the two outer wall panels positioned opposite to each other is in close contact with each other. Any shape may be used as long as it can form a sealing structure.

[Action]

According to the sealing structure between the outer wall panels according to the present invention,
Since each sealing portion of the sealing member mounted on the outer wall panel positioned adjacent to each other comes into close contact with each other and forms a double sealing structure therewith, without performing a step of separately incorporating a sealing body, A sufficient sealing effect can be obtained for the joint between the outer wall panels.

In particular, the sealing structure is formed at two places corresponding to the outer edge of the wooden board and the reinforcing frame behind it, and the sealing member on the side closely contacting the reinforcing frame is such that the reinforcing frame is located slightly inward of the wooden opening. As a result, the compression ratio can be increased, whereby the contact area between the sealing portions can be widened, and the sealing action can be reliably increased. Thus, it is possible to reliably prevent water or the like from entering the inside.

〔Example〕

Hereinafter, the present invention will be described in more detail based on embodiments of the present invention with reference to the accompanying drawings.

FIG. 4 shows one prior art of a sealing structure for an outer wall panel portion, in which a stud 2 is fixed to a unit structure (not shown). The outer wall boards 1, 1 having an arbitrary shape are mounted on the studs 2 via reinforcing frames 3, 3 by appropriate joining means.

A sealing member 5 is attached to the joint portion 4 of the two outer wall panels 1 and 1 mounted opposite to each other in order to prevent moisture, dust, and the like from entering the inside from the joint portion. It is later pressed.

The present invention relates to the improvement of the above sealing structure,
The structure of the lightweight steel frame structure and its studs, and the structure of the reinforcing frame for attaching the outer wall panel to the studs, can be the same as those conventionally known, and the outer wall board 1 can be used without any particular change. It is.

In the present invention, as shown in FIG. 1, the outer wall panel is integrally attached to the outer wall board 1 with a screw or the like (not shown) along the opening slightly inward of the opening 10 from the opening 10 thereof. , And the kiguchi part
Elastic sealing member for almost the entire length of 10 and reinforcing frame 3
20 are mounted in close contact. Attachment of the elastic sealing member 20 may be performed as one step in manufacturing the outer wall board 1, or may be performed at any time after the outer wall panel is manufactured and before the outer wall panel is attached to the stud 2. The mounting means is also optional, and is usually performed using an adhesive.

In this embodiment, the sealing member 20 is composed of a first sealing portion 21 having a U-shaped cross section and a second sealing portion 22 extending from the lip portion 10 to the back surface of the outer wall board 1. The U-shaped portion, which is the first sealing portion 21, is fitted to the opening 10 of the outer wall board 1. Then, in this state, the back surface of the second sealing portion 22 is
It is constituted so that it may adhere to.

Further, on the U-shaped portion which is the first sealing portion 21, two fin-shaped protrusions 23, 23 are formed integrally on the side opposite to the side of the outer wall board 1 in the length direction of the wood edge portion, The second sealing portion 22 has a substantially D-shaped convex portion 24 having a cavity therein, and its arc-shaped portion is also directed to the opposite side to the outer wall panel 1 side. It is integrally formed in the vertical direction.

Normally, the sealing member 20 is similarly attached to the opposite edge (not shown) of the outer wall board 1.

Next, a structure for sealing a joint between the outer wall panels by using the outer wall panel to which the above-described sealing member is attached will be described. FIG. 2 is a perspective view showing a sealing structure of a joint portion according to the present invention, in which two outer wall panels are fixed to the stat 2 at appropriate intervals by appropriate fixing means such as bolts. .

Sealing members 20, 20 attached to both outer wall panels
Has a symmetrical shape, and both fin-like projections 23, 23 contact each other in the front-rear direction as shown in the drawing, that is, in the thickness direction of the outer wall panel to form a first sealing portion. Further, the protruding portions 24 having a substantially D-shaped cross-section having a cavity therein are also in contact with each other at their leading end portions and in a flat state, so that the second
Of the sealing portion. As is clear from the figure, the first sealing portion has a sealing function at the position of the lip of the outer wall board, and the second sealing portion has a position of the reinforcing frame 3 attached to the outer wall board. Has a sealing function.

Further, the reinforcing frame 3 also functions as a back support for the second sealing portion 22.

FIG. 3 shows another embodiment of the elastic sealing member 20. In this example, the other configuration is the same except that the shape of the first sealing portion is different from that of the first embodiment. That is, in this example, the first sealing portion is also a D-shaped convex portion 26 having a cavity therein.

In the above description, the shape of the opposing elastic sealing members has been described as being left-right symmetric. However, the two pairs of elastic sealing members do not necessarily have to be left-right symmetric, As long as it is a combination of shapes that can fulfill the function of sealing, for example,
The shape shown in the figure may be used, and the other may be used in the shape shown in FIG.

Further, as a modified example of the elastic sealing member having the shape shown in FIG. 1, one and three fin-shaped protrusions are effective according to the use environment, and the tip of the D-shaped convex portion is also effective. It is also effective to further form appropriate irregularities.

〔The invention's effect〕

In the present invention, only a series of steps of first attaching one outer wall panel to the studs of the frame structure and then attaching the other opposing outer wall panel is performed. The opposing sealing members are in close contact with each other to form a sealing structure. Therefore, it is not necessary to attach a sealing member as a separate step after attaching the outer wall panel as in the conventional sealing structure of the joint portion, and the operation process can be simplified.

Further, in the present invention, the sealing structure is formed at two points corresponding to the lip of the outer wall board and the reinforcing frame behind the lip, and the sealing member on the reinforcing frame side has the reinforcing frame slightly inward from the lip. , The compression ratio can be increased, and thereby the contact area between the sealing portions can be widened, so that the sealing action is reliably increased. Even if the first sealing portion is damaged, the second sealing portion positioned corresponding to the reinforcing frame performs a reliable sealing function, thereby providing a frame structure or a reinforcing frame. Thus, it is possible to reliably prevent water from penetrating into the internal structure of the building, and to prolong the life of the building.

Further, when the sealing member is mounted simultaneously with the structure of the board as the outer wall panel base material, the sealing member also functions as a cushioning material, and is used when the outer wall panel is transported later or when the frame is mounted. Even when the tip of the outer wall board comes into contact with other things at the time of mounting work on the structure or the like, it is possible to prevent the outer wall board itself from being damaged.
