Abstract

PURPOSE:To improve workability of application of water proof by a method wherein a gasket comprises a resilient contact part having an upper outer surface forming a protruding curve, a bridge part in an X-shape in cross section supporting the resilient contact part from the back, a horizontal piece extended outwardly from the lower end of the resilient contact part, and a tip piece formed such that the tip of the horizontal piece is bent downward. CONSTITUTION:A gasket 3 for a panel lateral joint is formed of a resilient substance. A resilient contact part 4 is formed in an oval shape in cross section. The resilient contact part 4 is supported from the rear of the resilient contact part 4 by a bridge part 5 in an X-shape in cross section. Further, a horizontal piece 6 is extended outwardly from the lower end part of the resilient contact part 4, and a tip piece 7 is bent approximately at 45 deg. downwardly of the tip of the horizontal piece. When a lateral joint gasket 3 is pressed between upper and lower panels, the gasket is difficult to fall in a longitudinal direction and vertically compressed and set in a state to keep a desired position and shape.

Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Field of Application] This invention relates to a gasket for horizontal joints of panels such as vertically erected exterior wall panels.

[Prior art]

Examples of panels constituting the outer wall include ALC panels,
Sidings, precast concrete panels, etc. are used, but architectural amorphous sealants are generally used to waterproof the joints. On the other hand, in recent years, joint waterproofing has been carried out using gaskets, which are standard sealing materials, in order to equalize construction quality and save labor during on-site construction.

The conventional method using this gasket is shown in Figures 4 and 5.
As shown in FIG. 6, a common method has been to attach a gasket 2 to a panel 1 in advance and position the gasket 2 in the gap between the panels 1. In this case, both vertical joints and horizontal joints have the same details.

With this conventional method, the gasket attached to the panel is easily damaged during panel transportation or erection, and it is difficult to set the gasket in the specified position and shape, making it impossible to ensure sufficient waterproof performance. Ta. That is, the fifth
In the example shown in the figure, the upper and lower gaskets 2.2 compete with each other during construction, and the tips of the gasket 2 bodies do not come into contact with each other as shown in the figure (b), and sufficient reaction force cannot be obtained, resulting in low waterproofness. In the example shown in Figure 6, the piece of gasket 2 exposed to the outside side competes with panel 1 during construction and turns over, making it difficult to set it in the specified position and shape as shown in Figure (b), resulting in a poor appearance. There was a point.

Further, in the conventional example shown in FIG. 4, there was a problem that the gasket 2 would fall forward or backward when it was set between the upper and lower panels 1.1 as shown in FIG. 4(b).

[Problem to be solved by the invention]

As described above, the conventional waterproofing of panel joints using gaskets has many problems in terms of workability, appearance, and waterproofing performance. This invention is an attempt to solve these problems, and proposes a gasket for panel side joints that has good workability, excellent appearance design, and waterproof properties.

[Means to solve the problem]

The gasket for horizontal joints of a panel according to the present invention is a gasket for horizontal joints of a panel built vertically, and the gasket has an elastic contact portion whose outer upper surface has a convex curved surface, and a cross section X that supports the elastic contact portion from the back surface. It is characterized by comprising a horizontal piece projecting outward from the shaped bridge portion and the elastic lower end portion, and a tip piece bent downward at the tip end of the horizontal piece.

〔Example〕

The panel side joint gasket 3 of the embodiment shown in FIG.
Elastic contact portion 4 made of an elastic body and having an elliptical cross section; elastic contact portion 4;
A bridge part 5 with an X-shaped cross section that supports the elastic contact part on the back side, a horizontal piece 6 projecting outward from the lower end of the elastic contact part, and a tip piece 7 formed by bending the tip downward at 45 degrees. It consists of The elastic contact portion 4 has a horizontally elongated elliptical cross section, and is provided with a layer of elastic sponge on its upper surface.

Further, the joint portion of the end of the bridge portion with the elastic contact portion 4 has a thin bending point.

The horizontal joint gasket 3 of the embodiment shown in FIG. 2(a) is different from the gasket shown in FIG. has a convex curved surface. Further, like the gasket shown in FIG. 1, a bridge portion 5 having an X-shaped cross section is provided on the back surface of the elastic contact portion 4, and a horizontal piece 6 and a tip piece 7 protrude from the lower end. In addition, Fig. 2(b)
The horizontal joint gasket 3 shown in FIG. 1 is another embodiment in which a protrusion 8 is provided on the upper surface of the elastic contact portion 4.

In order to waterproof the horizontal joint between panels l and 1 using the gasket 3 shown in Fig. 2 (a), the chamfered protruding corner on the outside of the upper surface of the lower panel 1 built as shown in Fig. 3 (a) Attach the tip piece 7 and the horizontal piece 6 to the top, set the gasket, and fix with adhesive tape, etc. as necessary.On top of that, support the upper panel 1 with the support metal fittings 9 as shown in the figure (b), and set the specified joint spacing. The elastic contact portion 4 is compressed between the panels 1°1, and the joints are closed with gaskets 3.

In the above example, the joint spacing between panels 1.1 is 10 to 20.
+++m, the thickness of the elastic contact part 4 of the gasket 3 is 12 to 40
M and smaller than the gasket width. Also panel 1
The exterior sides and projecting corners of the building are treated with exterior materials such as sprayed wood, plastering material, metal material, tile material, ceramic material, and ceramic material. Note that the gasket shown in Figure 1 also
This gasket can be used in the same manner as the gasket shown in FIG. 2 to achieve the effects of the present invention.

[For production]

This horizontal joint gasket has a convex curved surface on at least the outer upper surface of the elastic contact part, and is supported by a bridge part with an X-shaped cross section from the back side, so it does not fall back and forth when pressed between the upper and lower panels, and is It can be compressed to maintain the desired position and shape. Therefore, the elastic contact portion has sufficient reaction force and is compressed with the convex curved surface facing outward, exhibiting high waterproof performance.

The horizontal piece and tip piece that protrude outward from the lower end of the elastic contact part can be attached to the upper corner of the panel and set in the correct position.The gasket will not fall back and forth, so you can work efficiently in the upper part. Panels can be installed. In addition, the tip piece functions as a drainer and can prevent water from seeping in from the bottom end of the gasket.

The width of the gasket 3 shown in FIG. 2 in which the inner portion of the elastic contact portion 4 is omitted can be made smaller than that of the gasket shown in FIG. 1. In FIG. 3, the weight of the panel is supported by the support hardware 9 provided between the panels 1.1, but by reducing the width of the gasket, it is possible to increase the size of the hardware 9.

〔Effect of the invention〕

This gasket for panel horizontal joints has good workability in waterproofing horizontal panel joints built vertically, and exhibits an excellent appearance and highly reliable waterproofing performance.
