Detailed Description

The technical solution in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of , but not all embodiments.

The outer board 1 is a fireproof gypsum board, the fireproof board taking gypsum as a base material develops quickly, the board has the main components of incombustibility and contains crystal water, the fireproof performance is better, the board can be used as a partition wall, a ceiling, a roof board and the like, the raw materials of the board are abundant, the factory setting production is facilitated, the dead weight is lighter, the building bearing can be reduced, the processing is easy, the board can be sawn and constructed conveniently, the decoration is good, but the bending resistance of the board is poorer, factors affecting the fire resistance performance of a gypsum board are more, such as composition components, board types, keel types, thicknesses, no filler in an air layer, an assembling mode and the like, in recent years, a silicon calcium gypsum fireproof board dimensional board, a double-sided paster gypsum board and other new varieties of a sponge board are provided, an outer board 2 is provided at the upper end of the inner board 1, a clamping groove 2 is provided at the edge of the inner board 1, an annular inner board dimensional board, a rectangular inner board fixing board, a sponge board fixing inner board fixing board is provided with a sponge board, a sponge board fixing baffle, a sponge board fixing a sponge 5, a sponge 5 is provided with a sponge board fixing board, a sponge fixing board is provided with four groups of sponge 6, a sponge fixing board, a sponge fixing board is provided with a sponge fixing board, a sponge fixing board fixing a sponge fixing board, a sponge fixing board fixing a sponge, a sponge fixing board, a sponge fixing.

The working principle is as follows:

, inserting four groups of fixing posts 9 from the outer side of the inner plate 1 respectively when mounting, ensuring that the baffle 12 faces downwards, then sleeving the springs on the fixing posts 9, and fixing the outer plate 2 on the inner plate 1 through the fixing holes, so that the clamping grooves 3 are clamped with the flanges 8.

The second step is that: the outer plate square groove 7 is in butt joint with the inner plate square groove 4 to wrap the sponge body 5 in the plate, and finally, the nuts 10 of the four fixed columns 9 are all installed in a rotating mode firmly, so that the whole external wall plate is assembled.

The third step: when using, cavernosum 5 can be effectual with the noise processing of external environment production and reduce, when meeting with the condition of a fire, baffle 12 can be heated, expandable graphite can be in the twinkling of an eye rapidly decomposed, produces a large amount of gases, makes graphite expand into the new material of worm form along the axial direction.

The fourth step: the expansion of baffle 12 can extrude inner panel 1, and the spring 11 of inner panel 1 contracts under pressure, and

inner panel

1 and 2 are closely laminated and are protected cavernosum 5, prevent that the heat from getting into and destroying cavernosum 5 between the two boards.

Finally, it should be noted that: although the present invention has been described in detail with reference to the foregoing embodiments, it will be apparent to those skilled in the art that modifications and variations can be made in the embodiments or in part of the technical features of the embodiments without departing from the spirit and the scope of the invention.
