Description

Technical Field

[0001] The utility model belongs to the technical field of prefabricated concrete walls, and in particular relates to a building sound insulation concrete wall. Background Art

[0002] Concrete wall refers to a general term for engineering composite materials that are cemented into a whole by cementitious materials. The term concrete usually refers to cement as a cementitious material, sand and stone as aggregates, and water (which may contain admixtures and additives) in a certain proportion, and the cement concrete obtained by mixing is also called ordinary concrete. It is widely used in civil engineering. At present, most buildings adopt frame structure. Except for the integral shear wall, other filling walls are mostly constructed by prefabricated concrete walls.

[0003] Prefabricated walls are reinforced concrete slab-shaped components processed in prefabrication plants or construction sites for building assembly. The use of prefabricated concrete wall panels to build assembled large-panel buildings can improve the degree of factory-based and mechanized construction, reduce on-site wet operations, save on-site labor, overcome seasonal influences, and shorten the construction period. At present, most of the assembled building wall panels are produced in factories with high quality and can be transported to the site for installation and construction. However, the existing assembled building wall panels are only soundproofed by external concrete materials during use, and the sound insulation effect needs to be improved. In addition, decorative wall panels are often installed on the indoor side of the existing building wall panels. When a fire occurs, the flames will quickly burn the decorative wall panels and the sound insulation materials inside the decorative panels, causing the fire to spread rapidly in the room, resulting in greater safety hazards and property losses. Utility Model Content

[0004] In order to solve the problems existing in the background technology, the utility model provides a building sound insulation concrete wall.

[0005] The utility model provides a building soundproof concrete wall, comprising a concrete wall body, a plurality of steel bars are arranged in a staggered manner in the transverse and longitudinal directions inside the main body of the concrete wall, a plurality of sound-absorbing holes arranged in a rectangular array are arranged on the main body of the concrete wall, the sound-absorbing holes are filled with sound-absorbing cotton, fixed grids are connected to both sides of the concrete wall, sound-absorbing panels are filled between the fixed grids, a sound insulation mechanism is arranged inside the grid, the sound insulation mechanism is composed of a sound insulation board layer, a sound insulation cotton layer and a sound insulation felt sleeve from the inside to the outside, a gypsum board is arranged on the outside of the fixed grid, and a decorative panel is clamped on the outside of the gypsum board through a plurality of limit slots.

[0006] Furthermore, the plurality of steel bars are staggered between the plurality of sound-absorbing holes.

[0007] Furthermore, the fixed grid is made of metal, and the fixed grid is fixedly connected to the concrete wall by rivets.

[0008] Furthermore, the sound insulation board layer, the sound insulation cotton layer and the sound insulation felt sleeve have the same thickness, and the edge of the sound insulation felt sleeve is wrapped around the edge of the sound insulation board layer and the sound insulation cotton layer.

[0009] Furthermore, a plurality of connecting plates are provided on one side of the fixed grid located on the sound insulation felt sleeve, and the gypsum board is fixedly connected to the plurality of connecting plates by a plurality of bolts.

[0010] Furthermore, the plurality of limit slots are arranged horizontally with the ground, and the plurality of limit slots are arranged equidistantly, and both sides of the plurality of limit slots penetrate the entire gypsum board.

[0011] Beneficial effects of the utility model:

[0012] 1. The soundproof concrete wall of this building reduces the noise passing through the main body of the concrete wall by setting multiple sound-absorbing holes on the main body of the concrete wall. At the same time, the sound insulation structure fixed in the fixed frame on both sides can effectively reduce the transmission of internal and external noise and increase the sound insulation performance of the soundproof concrete wall;

[0013] 2. The soundproof concrete wall of this building is made by setting gypsum boards on the outside of the soundproof structure wrapped by the fixed grid. The gypsum boards can effectively isolate the flames of the burning external decorative panels, thereby slowing down the speed of the fire spreading indoors, protecting the walls and buying more time for rescue.
