Description

Technical Field

[0001] The utility model relates to a heat-insulating and sound-insulating board for a building exterior wall, belonging to the technical field of construction. Background Art

[0002] Sound insulation boards are mostly used on the exterior walls of buildings. The main function of sound insulation boards is to isolate external noise to achieve a quiet effect indoors. In theory, general objects have sound insulation effects, but we call boards with an average sound insulation value (in an infinite space, an infinite material is placed between the sound source and the measured point) exceeding 30dB as sound insulation boards. Therefore, sound insulation boards are generally high-density materials.

[0003] In the prior art, when installing the thermal insulation sound insulation board used for the building exterior wall, an adhesive is generally sprayed on the wall, and then the thermal insulation sound insulation board is pasted on the wall, and finally the thermal insulation sound insulation board is fixedly connected to the wall using expansion bolts. However, the expansion bolts will destroy the structure of the thermal insulation sound insulation board when used, affecting the thermal insulation and sound insulation effect of the thermal insulation sound insulation board. At the same time, the thermal insulation sound insulation boards on the left and right sides cannot be sealed when spliced, thereby affecting the waterproof effect of the thermal insulation sound insulation board.

By arranging a mounting bracket and a positioning strip, the mounting bracket can be fixed on the wall through the mounting plate, and the positioning strip can drive the thermal insulation sound insulation board body to be connected to the mounting bracket, so that the thermal insulation sound insulation board body does not need to be fixed by using expansion bolts to punch holes, so as to prevent the expansion bolts from damaging the thermal insulation sound insulation board body structure and affecting the thermal insulation sound insulation effect of the thermal insulation sound insulation board body. At the same time, the thermal insulation sound insulation board body is respectively provided with a connection area and a bayonet area on both sides, and the connection area can be inserted into the bayonet area, so that the thermal insulation sound insulation board bodies adjacent to the left and right can be connected to each other. At the same time, a rubber sealing strip is provided inside the bayonet area, which can increase the sealing performance of the connection area in the bayonet area, thereby improving the waterproof performance of the thermal insulation sound insulation board body when connected, so as to solve the problems raised in the above-mentioned background technology.
