[0013] The following further elaborates on the utility model in detail with reference to the drawings and specific embodiments.

[0014] As Figures 1-3 shown, a prefabricated heat-insulating and sound-insulating laminated board for building use in combination includes a first laminated board 1, a quick connection device 2, a second laminated board 3, a truss steel bar 4, a support steel bar 5, and a heat-insulating and sound-insulating board 6. The first laminated board 1 is connected to the second laminated board 3 at the right end through the quick connection device 2. Truss steel bars 4 are installed at the tops of the first laminated board 1 and the second laminated board 3. Support steel bars 5 are installed inside the first laminated board 1 and the second laminated board 3 in an equidistant and symmetric distribution. Heat-insulating and sound-insulating boards 6 are installed at the bottoms of the first laminated board 1 and the second laminated board 3.

[0015] The quick connection device 2 includes a connection frame 7, a steel bar insertion hole 8, a countersunk threaded hole 9, a countersunk bolt 10, a rubber sealing ring 11, and a steel bar limiting block 12. The support steel bars 5 at the connection of the first laminated plate 1 and the second laminated plate 3 are inserted into the steel bar insertion holes 8 on both sides of the connection frame 7. Countersunk screw holes 9 are symmetrically distributed at equal intervals at the top of the connection frame 7. Countersunk bolts 10 connected by threads are installed inside the countersunk screw holes 9. A rubber sealing ring 11 with an annular structure is nested on the circumferential surface of the countersunk bolt 10. A steel bar limiting block 12 connected by hinge is installed at the bottom of the countersunk bolt 10.

[0016] The heat-insulating and sound-insulating board 6 includes an installation inner board 13, a first sound-insulating board 14, an aerogel heat-insulating layer 15, a second sound-insulating board 16, and a waterproof decorative outer board 17. The installation inner board 13 is fixed to the bottom ends of the first laminated plate 1 and the second laminated plate 3 by expansion screws. A first sound-insulating board 14 fixed by adhesion is installed at the bottom of the installation inner board 13. An aerogel heat-insulating layer 15 fixed by adhesion is installed at the bottom of the first sound-insulating board 14.

A waterproof decorative outer board 17 fixed by adhesion is installed at the bottom of the second sound-insulating board 16.

[0017] The working principle of the present utility model: First, the support steel bars on both sides of the laminated plates to be connected are symmetrically inserted into the steel bar insertion holes on both sides of the connection frame at equal intervals. Then, by rotating the countersunk screw, the steel bar limiting block is driven to descend and contact the two groups of steel bars, thereby achieving locking and completing the connection. At the same time, the space between the countersunk bolt and the countersunk threaded hole is filled with a rubber sealing ring to reduce the entry of water vapor into the steel bar insertion hole to corrode the steel bar. Then, the sound insulation effect of the laminated plate is improved by the two sound-insulating boards inside the heat-insulating and sound-insulating board, and further, a good heat insulation and heat preservation effect is provided by the aerogel heat-insulating layer.

[0018] The above is a preferred embodiment of the present utility model. For those of ordinary skill in the art, according to the teachings of the present utility model, without departing from the principle and spirit of the present utility model, the changes, modifications, substitutions, and variations made to the implementation manners still fall within the protection scope of the present utility model.
