Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a window frame used for curtain walls, sashes, top lights and the like, and more particularly to a window frame gasket for an opening window in which the opening curtain wall is fixed by a zipper type gasket.

[0002]

2. Description of the Related Art As a method for fixing a surface material such as glass or panel used for a curtain wall of a building to a supporting frame thereof, there are a ridge construction method (sealing construction method) and a gasket construction method. The former is a wet method in which glass as a curtain wall is fixed by injecting and fixing a gel-like sealing material on its supporting member, so that it requires skill to install and the workability is inferior and replacement of the surface material is required. Have difficulty. Moreover, its durability is weak and it is necessary to change the sealing material in a cycle of 5 to 10 years. On the other hand, the latter gasket construction method is a dry construction method in which the support member and the edge of the face material are fixed to each other through an elastic gasket having a fixed shape, so that the mounting work is simple and the workability is excellent, Moreover, the replacement of the face material becomes easy. There are so-called Y-type and H-type gaskets depending on the application, and various types of materials are considered.

In the zipper type gasket construction method, when gripping the edge of glass into the gasket which is an elastic body and stopping it, first the zipper portion of the gasket is removed, the glass is inserted, and then the zipper is inserted with a jig. It is a common method to stop the glass by giving repulsive force. A zipper-type gasket provided with a zipper for fastening the face material to the gasket by means of
No. 62-110428, JP-A-1-16333.
No. 40 and the like. Gaskets are made of chloroprene rubber (CR), ethylene / propylene /
Due to improvements in terpolymer (EPT) and silicone-based synthetic rubber, the durability is extremely high and is said to last for 40 years or more. It is evaluated as an important construction method for curtain walls, top lights, etc. in durable buildings.

FIG. 6 is a perspective view of a conventional window frame using the above-mentioned zipper type gasket construction method among the window frames in the curtain wall, and FIG. 7 is a sectional view taken along the line EE of FIG. is there. In the figure, 101 is blind and 1
Reference numeral 02 denotes a fixed frame made of aluminum, and the fixed frame 102 is fixed to the seamless 101 by a so-called HF type gasket 103 made of an elastic material such as chloroprene rubber. 1
Reference numeral 04 is a zipper, and 110 is a tight material. The window opening is supported by an aluminum shoji frame 105, and hinges 1
It is rotatable with respect to the fixed frame 102 by 06, and the four sides of the glass 106 are fixed to the shoji frame 105 by an H-shaped gasket 107 and a zipper 108.

The load of the window frame is supported on the four sides by the gasket 103, and is directly or indirectly received by the bracket 112 and the bolts 111 by the bolts 111. .

To mount the window frame, the fixed frame 102 is inserted from the outside (outside the room) and fitted into the groove of the gasket 103, and then the bracket 112 is made invisible (or upright) 101 with the fixed frame 102 with bolts 111. Join.

[0007]

In recent years, the appearance design of durable buildings such as high-rise buildings, department stores, museums, museums, pavilions, etc. has become extremely important. There are cases in which the lighting adjustment device including the ones impedes the degree of freedom in designing the design of the entire building. Therefore, in the window portion of the building, the surface of the face material such as the glass panel that constitutes the same is the same as the other outer surface of the building, and the finding in the opening portion of the window is reduced. Is desired.

Since the conventional opening gasket such as a window frame has a large external finding S, there is a problem in designing the exterior design in the window structure portion of the curtain wall. Further, since the zipper is provided outdoors, there is a problem that an outdoor scaffold is required for attaching the plate material. Regardless of new construction, providing temporary scaffolding outdoors for work in repairing or repairing the completed building does not require external scaffolding because it will be a burden on the cost and construction period. It is required that gaskets and face materials can be replaced.

The present invention was created in view of the above-mentioned conventional technique, and an object of the present invention is to provide a gasket for an opening window frame which has a small external finding and has an extremely good workability in mounting and replacement.

[0010]

According to the present invention, an opening window in which an end portion of a plate material of a curtain wall is fitted, the size of the external finding is smaller than the internal size of the indoor side, and a zipper is provided on the indoor side. It is a frame gasket. In the gasket structure, a fitting groove for fitting each end of the plate material (curtain wall) and the shoji frame is not provided as in the prior art, but a fitting only for fitting the end portion of the plate material. Has a groove. Then, the outside of the gasket is fitted into the shoji frame, and is fixed by a zipper from the indoor side.
