Description

[Detailed Description of the Invention] <Industrial Field of Application> The present invention relates to a horizontal joint waterproofing structure of an outer wall of a building in which an outer wall panel is installed laterally.

<Prior art> Conventionally, the so-called horizontal cladding method has been popular, in which outer panels such as corrugated slate boards are overlapped at their ends and laid horizontally to form the outer wall of a building. A synthetic resin sponge or rubber gasket is sandwiched between the overlapped portions, that is, the horizontal joints, and this provides waterproofing to the horizontal joints. However, even with this structure, the waterproof effect is not sufficient, and improvements are desired.

<Problems to be Solved by the Invention> The present invention aims to further enhance the waterproofing effect of the above-mentioned horizontal joint portion, and to obtain a horizontal joint structure having permanent waterproofness.

<Means for Solving the Problems> The present invention provides a structure in which an elastic water stop plate is attached to the gap between the overlaps of outer walls of a building in which outer walls, preferably corrugated outer walls, are horizontally installed. , and a horizontal joint structure characterized in that a nonwoven fibrous body is press-fitted inside the water stop plate.

Fig. 4 is a cross-sectional view showing the horizontal joint part of the outer wall plate formed by the conventional horizontal construction method.
A resilient water stop plate 3 made of sponge or the like is sandwiched between the two.

In this conventional horizontal joint structure, the present invention provides, as shown in FIG.
A water stop plate 3 having elasticity made of synthetic resin, rubber, etc. or a closed foam thereof is loaded, and a nonwoven fibrous body 5 is press-fitted inside the water stop plate 3. For more completeness, it is preferable to provide the nonwoven fiber body 4 also outside the water stop plate 3, as shown in FIG.

This non-woven fibrous body is made of natural fibers, synthetic resins, and inorganic fibers, and these webs are made singly or layered, and the fibers are entangled by needle punching or fluid entangling means, or the fibers are bonded together using an adhesive or the like. Non-woven fabric sheets or mats cut into strips are used.

This fibrous body is press-fitted into the joint, and is 1 mm
~10mm thick is effective.

Further, the water stop plate 3 of the present invention may be a band-shaped body having a rectangular cross section, but as shown in FIGS.
It is preferable to have the following. This is because when the protrusion is press-fitted into the joint, the protrusion deforms and
This is effective in increasing the adhesion of the water stop plate on the outer wall plate surface.

Furthermore, in the present invention, the waterstop plate and the nonwoven fibrous body may be joined to each other and integrated, and in this case, it is convenient during construction.

The structure of the present invention is achieved by temporarily or permanently adhering a water stop plate and a nonwoven fibrous material to the edge surface of the outer envelope plate 1 or 2, and then stacking the outer envelope plates and laying them horizontally. You can get it easily. In addition, Figures 1 and 4
In the figure, 7 indicates a channel and 8 indicates a bolt.

<Functions and Effects> According to the present invention, rainwater that enters through the joints is
Water stop plates can stop most of them from entering. Even if rainwater were to enter the building through the gap between the water stop plate and the outer wall, it would be absorbed by the inner fibers and would not leak into the building. Moreover, the rainwater absorbed by the non-woven fibrous body can be removed by, for example, using a similar non-woven fibrous body as a joint material in the vertical joint portion, and bringing this vertical joint material into contact with the fibrous body having the horizontal joint structure of the present invention. If arranged in this way, the rainwater absorbed by the non-woven fibrous body of the structure of the present invention can be discharged to the outside through the fibrous body of the vertical joints, so the waterproofing effect of the horizontal joints is high and semi-permanent. becomes.
