Detailed Description
The following describes embodiments of the present invention with reference to the drawings and examples, and the parts of the present invention not described in the present invention can be realized by using or using the existing technologies.
It should be noted that the structure, ratio, size and the like shown in the drawings of the present specification are only used for matching with the content disclosed in the specification, so as to be known and read by those skilled in the art, and are not used for limiting the limit conditions that the present invention can be implemented, and any modification of the structure, change of the ratio relationship or adjustment of the size should still fall within the scope that the technical content disclosed in the present invention can cover without affecting the efficacy that the present invention can produce and the purpose that the present invention can achieve.
Meanwhile, the terms such as "upper", "lower", "left", "right", "middle" and "one" used in the present specification are for convenience of description, and are not intended to limit the scope of the present invention, and changes or adjustments of the relative relationship thereof may be made without substantial technical changes, and the present invention is also regarded as the scope of the present invention.
As shown in fig. 1, a multi-chamber fireproof profile comprises a plurality of chambers, wherein each chamber is composed of a plurality of frames 4; the expansion joint further comprises a connecting piece 1, an intermediate piece 2 and an expansion strip 5, wherein the connecting piece 1 is arranged on one side of the frame 4, the intermediate piece 2 is arranged in the middle of the frame 4, and the expansion strip 5 is arranged on one side of the frame 4.
The connecting piece 1 is a plate made of metal material and used for connecting and fixing. The intermediate member 2 is a plastic member made of polyvinyl chloride, and the intermediate member 2 is a poor conductor of heat. The expansion strips 5 are strip-shaped structures made of graphene materials, and the expansion strips 5 expand when heated.
The connecting piece 1 is connected with the frame 4 by screws. The frame 4 is a frame structure made of aluminum alloy or steel. The frame 4 is provided with a projection for connection. One end of the intermediate piece 2 is clamped with a projection on the frame 4. The expansion strip 5 is clamped with the bulge on the frame 4 or connected with the frame 4 through a screw.
The utility model discloses select the quantity of frame 4 according to actual need, the structure of frame 4 is not unique. The utility model discloses a multi-chamber structure is made up into to the connection of frame 4, middleware 2. The utility model discloses in practice, can regard as door and window's main combination part. The frame 4 can be connected to the connecting device 3 and can be rotatably connected to other components via the connecting device 3.
