Abstract

PURPOSE: To improve construction efficiency and stability of construction work thereby to achieve reduction of costs in a sealing operation of a horizontal joint of an exterior wall by providing an exterior wall seal material having both sealing function and spacer function. CONSTITUTION: In an exterior wall panel seal material 1 having a construction such that a second seal part 12 of thin plate shape extends from the lower edge of the inner end of a first seal part 11 of approximately rectangular shape in cross section and a third seal part 13 of thin plate shape extends from the lower edge of the outer end of the seal part 11, the first, second, third seal parts 11, 12, 13 are formed from sponge rubber by coextrusion of sponge rubber and solid rubber. A receiving part having approximately rectangular cross section is formed at the lower edge of the seal part 12, and the receiving part is formed from solid rubber.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a sealing material for outer wall panels of buildings.

[0002]

2. Description of the Related Art Conventionally, as shown in FIGS. 4 and 5, outer wall panels 5 made of concrete or the like having an upper end surface having a convex cross section and a lower end surface having a concave cross section are vertically stacked to form a horizontal joint between the outer wall panels. The caulking material 3 is applied along the outer surface of the outer wall panel, and the lower edge of the inner end of the first seal portion 21 having a substantially rectangular cross section and the upper edge of the outer end of the second seal portion 22 having a substantially rectangular cross section are formed in a thin plate shape. A seal structure for an outer wall panel provided with a seal material 2 which is connected by a third seal portion 23 and extends a thin plate-shaped fourth seal portion 24 from a lower edge of an outer end of the first seal portion 21 is known. (See Japanese Utility Model Laid-Open No. 6-79908).

[0003]

However, since the above-mentioned sealing material is an extruded product of a sponge rubber simple substance and does not function as a spacer, the joint width (horizontal joint) width changes with time over a long period after construction. However, there is a problem in that a separate spacer is required.

The object of the present invention is to improve the workability and the work stability in the sealing work of the lateral joints of the outer wall panel, and to reduce the work cost because no additional spacer is required. An object is to provide an outer wall panel sealing material.

[0005]

As a result of earnest research to achieve the above-mentioned object, the present inventor has constructed the first, second and third seal portions with sponge rubber, and has the second configuration. It has been found that an outer wall panel sealing material having both a sealing function and a spacer function can be provided by providing a receiving portion on the lower edge of the sealing portion, and by configuring this with solid rubber, the present invention has been completed. Is.

That is, the outer wall panel sealing material 1 of the present invention
Extends the thin plate-shaped second seal portion 12 to the inner edge lower edge of the first seal portion 11 having a substantially rectangular cross section, and extends the thin plate-shaped third seal portion 12 from the outer edge lower edge of the first seal portion 11. Seal part 1
In the outer wall panel sealing material 1 formed by extending 3, the first, second and third sealing portions 11, 12, 13 are made of sponge rubber, and the lower edge of the second sealing portion 12 has a substantially rectangular cross section. The receiving portion 14 is formed and is made of solid rubber.

The outer wall panel sealing material 1 comprising the first to third sealing portions and the receiving portion of the present invention can be integrally molded by coextrusion of sponge rubber and solid rubber, and the material is not particularly limited. . However, the hardness of the solid rubber is preferably 85 ° (JIS-A) or more.

Further, in the present invention, it is desirable to attach the adhesive tape 6 along the inner surface of the outer wall panel sealant 1.

[0009]

According to the outer wall panel sealing material 1 of the present invention, the first, second and third sealing portions 11, 12 and 13 are made of sponge rubber so as to ensure the sealing function and to secure the receiving portion 14. Since the sealant is provided with a spacer function by being composed of solid rubber, the joint (lateral joint) width does not change over time for a long period after construction.

[0010]

EXAMPLES As shown in FIG. 1, the sealing material 1 of the present invention is
The lower edge of the inner end of the first seal portion 11 made of sponge rubber and having a rectangular cross section and the upper edge of the outer end of the receiving portion 14 made of solid rubber and having the same rectangular cross section are used as a thin plate-shaped second seal made of sponge rubber. It has a structure in which the third seal portion 13 in the form of a thin plate extends from the lower edge of the outer end of the first seal portion 11 by being joined flush with each other by the portion 12, and sponge rubber and solid rubber are coextruded by coextrusion. It is integrally molded. The adhesive tape 6 is attached along the inner surface of the sealing material 1.

FIG. 2 is a perspective view showing the outline of the seal material 1 of the present invention assembled to an outer wall panel, and FIG. 3 is a vertical sectional view of a portion A in FIG. As shown in FIG. 3, the sealing material 1 includes first, second and third sealing portions 11, 1
2 and 13 are attached along the inner surface of the sealing material 1 in advance so that the top surface and both side surfaces of the protruding upper end surface of the outer wall panel are covered and the receiving portion 14 receives the inner edge of the upper end surface. The adhesive tape 6 is adhered and fixed to the convex upper end surface of the outer wall panel 5. In the figure, 3 is a caulking material, and 4 is a backup material made of expanded polyethylene.

[0012]

As described above, according to the present invention, since it is possible to provide the outer wall panel sealant having both the sealing function and the spacer function, it is possible to perform the construction work and the construction work in the sealing work of the lateral joint of the outer wall panel. The stability is improved, and the cost of construction is reduced because a separate spacer is not required.
