Description

[Detailed description of the invention]

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a fire-resistant joint gasket to be inserted into a joint formed at a joint of panels such as an outer wall and a floor of a fire-resistant building.

[0002]

2. Description of the Related Art A description will be given with reference to FIGS. Conventionally, joint portions 3 formed at butting portions 2a, 2a of panels 2, 2 such as outer walls and floors stretched on the outer surface of a frame material 1 of a fire-resistant building.
As shown in FIG. 3 to FIG. 8, there are various types of fireproof joint gaskets to be inserted into the gasket, such as a combination of a rubber material and a noncombustible material. First, the one shown in FIGS. 3 and 4 is one in which the non-combustible core material 15 is inserted into the cavity V provided in the rubber main body 14 from the cutout Q on the rear side and embedded therein, as shown in FIGS. 5 and 6. The thing is the noncombustible material 2 on the back surface of the rubber body 24.
5 and shown in FIG. 7 and FIG.
A plate-like portion 34a extending on both sides on the back side of the rubber body 34
The metal plate 35 is overlapped on the back surface of the frame member 1 and sandwiched between the frame material 1 and the panels 2 and 2. Further, what is shown in FIG.
Foamable refractory paint 4 on back of irregular elastic sealing material 44
5 are stacked and filled.

[0003] However, in the above conventional device,
In the case of combining a rubber material with a non-combustible material, a step of combining the two is required, and a large amount of time is required for the combination work, curing of the sealing material, and the like, resulting in an increase in cost. In addition, there is a problem that an accident such as falling off or peeling of the incombustible material occurs.

[0004]

The problems to be solved are that it takes a lot of time for the construction, the cost is high, and accidents such as falling off and peeling of the incombustible material are caused.

[0005]

A description will be given with reference to FIGS. 1 and 2. FIG. The gasket 4 for fireproof joints according to the present invention is a gasket 4 for jointing a fireproof gasket 4 to be inserted into joints 3a formed at butting portions 2a of panels 2, 2 such as outer walls and floors stretched on the outer surface of a frame 1 of a fireproof building. A gasket main body 4a made of a flame-retardant rubber material and a seal lip 4c for sealing between the main body 4a and the panel butting portion 2a, and a core material made of a foamable refractory material by simultaneous molding by co-extrusion. 4b is buried and immersed in the main body 4a, and the refractory core material 4b foamed at the time of heating and the panel butt 2
The seal lip 4c is positioned so that the seal lip 4c is sandwiched between the seal lip 4c and the seal lip 4c.

[0006]

DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment will be described. 1 is a frame material for extending panels 2 and 2 such as an outer wall and a floor of a building, and 3 is panels 2 and 2
Joints formed at the butting portions 2a, 2a. The refractory joint gasket 4 fitted into the joint portion 3 is obtained by simultaneously molding a gasket main body 4a made of a flame-retardant rubber material and a core material 4b made of a foamable refractory material by co-extrusion.
The foamable refractory foams when exposed to a flame, forms a carbonized layer, and has a property of preventing further penetration of the flame.

In the case where the gasket main body 4a is provided with a seal lip for sealing between the gasket main body 4a and the panel butting portion 2a, the seal lip 4c is sandwiched between the refractory core material 4b foamed during heating and the panel butting portion 2a. The seal lip 4c is positioned as described above.

The operation of the gasket for refractory joint according to the present invention is stable and high in quality because it is co-extruded and co-molded, and does not require a combination of materials and parts on site. The construction is easy and extremely simple, the construction time is greatly reduced, and the cost is reduced.

[0009]

[Effect of the Invention] Since the present invention is configured as described above,
Stable quality, including fire resistance, simplifies construction on site, and reduces costs.
