Abstract

(57) [Summary] [Purpose] To provide a dry joint material whose waterproof performance is maintained for a long period of time and which has the same workability as a normal gasket joiner during construction. [Structure] The water-expandable rubber elastic sealing material 4 was attached to a waterproof portion that is easily exposed to water.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a dry joint material used for waterproofing joints such as outer walls.

[0002]

[Prior Art]

 As a conventional dry joint material, there is a deformed molded elastic plastic gasket joiner with a tree-shaped cross section, but this gasket joiner is inserted between the wood mouth faces of the plate material, and it has a waterproof function by its elasticity and shape effect. ..

[0003]

[Problems to be solved by the device]

 In the above-mentioned conventional gasket joiner, the adhesion restoring force is reduced due to the shrinkage of the plate material and the weather resistance of the elastic plastic, and as a result, the waterproof function is lost.

An object of the present invention is to provide a dry joint material which maintains a sufficient waterproof function for a long period of time and has the same workability as that of an ordinary gasket joiner at the time of construction.

[0005]

[Means for Solving the Problems]

 A feature of the dry joint material according to the present invention is that a water-expandable rubber elastic seal material is attached to a waterproof portion that is easily exposed to water.

[0006]

[Action]

 Since the water-expandable rubber elastic sealant is attached to the waterproof part that is easily exposed to water, when it is exposed to water, it expands to more than double the volume and exhibits waterproof performance. Workability similar to that of a joiner can be obtained.

[0007]

【Example】

 An embodiment of the present invention will be described below with reference to FIGS. 1 and 2.

Reference numeral 1 is a gasket joiner. The gasket joiner 1 has an iron plate 2 whose center portion is bent upward in an inverted U shape, an elastic plastic 3 having a tree-shaped cross section to be applied on the iron plate 2, and water expansion applied to an outer side branch portion 3a of the elastic plastic 3. It consists of rubber elastic sealing material 4. Since the water-expandable rubber elastic seal material 4 is made of commercially available water-expandable rubber ADEKA ULTRA SEAL (trademark), it expands to a volume more than double when exposed to water.

FIG. 1 shows a gasket joiner 1 inserted between the outer wall materials 5 and 5 and the wall base material 6. When exposed to water, the sealing material 4 expands more than twice, so that the waterproof function can be sufficiently fulfilled. Further, at the time of construction, since the thickness of the sealing material is small, it has the same workability as a normal gasket joiner.

Reference numeral 11 shows another gasket joiner. The gasket joiner 11 has an iron plate 2 whose center portion is bent upward in an inverted U shape, a tree-shaped elastic plastic 13 to be attached to the iron plate 2, and a cross-sectional angle to be attached to both sides of a neck portion 13a of the elastic plastic 13. The mold comprises a water-expandable rubber elastic sealing material 14.

FIG. 2 shows a gasket joiner 11 inserted between the outer wall members 5 and 5 and the wall base member 6. When exposed to water, since the gasket Joyner 11 the sealing member 14 similarly to the gas gasket Joyner 1 shown in FIG. 1 is expanded, it is possible to perform a waterproof function to the charge amount. Further, at the time of construction, since the thickness of the sealing material 14 is small, it has exactly the same workability as a normal gasket joiner.

[0012]

[Effect of the device]

 As can be understood from the above description, the dry joint material according to the present invention has a sufficient waterproof function and has the same workability as a normal gasket joiner during construction.
