Composite environment-friendly material sound insulation board

Abstract

The invention relates to a composite environment-friendly material sound insulation board which comprises a metal plate, a wood plate and a gypsum plate, the metal plate is arranged between the wood plate and the gypsum plate, a sound insulation damping felt is arranged at the top end of the wood plate, grooves are formed in the upper surface and the lower surface of the metal plate, fixing grooves are formed in the side walls of the grooves, and first electromagnets are arranged in the fixing grooves. Protruding blocks are fixedly arranged on the faces, making contact with the metal plate, of the wood plate and the gypsum plate, the protruding blocks are arranged in the grooves, through holes are formed in the protruding blocks in the horizontal direction in a penetrating mode, placing bins are arranged in the protruding blocks in the vertical direction, the placing bins penetrate through the through holes, second electromagnets are arranged in the placing bins, and fixing columns are arranged in the through holes and the fixing grooves. The length of the fixing column is smaller than half of that of the through hole. Through the first electromagnet, the second electromagnet and the fixing column, the protruding blocks and the grooves can be conveniently fixed and separated, time and labor are saved when the metal plate is recycled, and the problem that an adhesive is not prone to being removed is solved.

Description

technical field [0001] The invention relates to the technical field of ring sound insulation boards, in particular to a sound insulation board made of composite environmental protection materials. Background technique [0002] Sound insulation board is a general term for sound insulation materials, including flat hard and rollable flexible board sound insulation materials, etc. Sound insulation boards are used to cut off unwanted sound transmission, and are often composed of materials with good sound insulation properties. There are various sound insulation materials. The more common ones are solid bricks, reinforced concrete walls, wood panels, gypsum boards, iron plates, sound insulation felts, fiberboards and so on. With the improvement of living standards, the construction industry's standard requirements for houses have also increased accordingly. According to different uses, different requirements have been put forward for the sound insulation performance of houses. At...
