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

[0002] Shear wall is a type of concrete wall, and its structure can be built higher than frame structure. It is the main vertical component of reinforced concrete cast-in-place, which mainly bears all vertical gravity loads of the house and all horizontal loads and earthquake horizontal effects on the house. Shear wall is a non-single-shaped component composed of wall body, various edge components, connecting beams, etc. The edge components and wall concrete are integrated, and vertical steel bars and stirrups or hook bars are added. In order to increase the construction speed of the building, concrete shear walls can be produced by prefabrication, that is, precast concrete shear walls.

[0003] Precast concrete shear walls have a wide range of applications and can be used in various building types such as high-rise buildings, large commercial buildings, industrial plants, etc.

[0004] Precast concrete shear walls, as the walls of high-rise buildings, play the role of space division. In order to avoid the privacy of each space and avoid noise pollution, precast concrete shear walls need to have sound insulation effects.

[0005] In view of this, in order to make the precast concrete shear wall have good sound insulation, avoid noise impact and ensure the privacy of people in each space, we provide a concrete shear wall with good sound insulation effect. Utility Model Content

[0006] The purpose of the utility model is to provide a concrete shear wall with good sound insulation effect, aiming to solve the problem that the existing prefabricated concrete shear wall has poor sound insulation effect, thereby being affected by noise in adjacent spaces and at the same time leaking its own privacy. For this purpose, we provide a concrete shear wall with good sound insulation effect.

[0007] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a concrete shear wall with good sound insulation effect, comprising a concrete wall body, longitudinal steel bars and transverse steel bars, the interior of the concrete wall body is penetrated by longitudinal steel bars, the interior of the concrete wall body is penetrated by transverse steel bars, and the transverse steel bars are ring-shaped steel bars; the side surface of the concrete wall body is connected to a sound-absorbing concrete layer, the outer side of the sound-absorbing concrete layer is connected to a reflective wall brick, the groove of the reflective wall brick is filled with a filler, the reflective wall brick and the outer side of the filler are fixedly connected with a hanging net, the outer side of the hanging net is connected to a slurry layer, the outer side of the slurry layer is connected to a gypsum board, and the surface of the end of the transverse steel bar is connected to a docking mechanism.

[0009] In order to facilitate the reflection of noise sound waves, as a preferred concrete shear wall with good sound insulation effect of the utility model, the reflective wall bricks are made of ceramic material, and the side surface of the reflective wall bricks is set as a concave structure.

[0010] In order to absorb the reflected noise waves conveniently, as a preferred concrete shear wall with good sound insulation effect of the utility model, the filler is made of glass fiber, and the filler is glued in the groove of the reflective wall tile by glue.

[0011] In order to reinforce the walls of two shear walls, as a preferred concrete shear wall with good sound insulation effect of the utility model, the docking mechanism includes a fixing sleeve, a first fixing hole, a second fixing hole, a fixing bolt and a fixing nut. The fixing sleeve is sleeved on the surface of the end of the transverse steel bar. The surface of the fixing sleeve is provided with a first fixing hole, and the surface of the fixing sleeve is provided with a second fixing hole.

[0013] Compared with the prior art, the beneficial effects of the utility model are:

[0014] 1. The smooth inner grooves of the reflective wall tiles can reflect sound waves, and the reflected sound waves can be absorbed by the filler.

[0026] Preferably, the sound-absorbing concrete layer 4 is a mixture of perovskite material, mineral wool board, acoustic foam or aluminum silicate felt and concrete, and the amount of perovskite material, mineral wool board, acoustic foam or aluminum silicate felt added is between 5% and 10% of the total weight of the concrete.

[0027] When used specifically, the perovskite material, mineral wool board, acoustic foam or aluminum silicate felt has a sound-absorbing effect, and the sound waves can be absorbed by these sound-absorbing materials when passing through the sound-absorbing concrete layer 4 .

[0028] Preferably, the reflective wall tile 5 is made of ceramic material, and the side surface of the reflective wall tile 5 is arranged as a concave structure.

[0029] During specific use, the reflective wall tile 5 is made of ceramic material, so the surface of the concave part thereof is very smooth, and thus the sound waves can be reflected.

[0030] Preferably, the filler 6 is made of glass fiber, and is glued into the groove of the reflective wall tile 5 by glue.

[0031] During specific use, the sound waves reflected by the reflective wall tiles 5 can be absorbed by the filler 6 .

[0032] Preferably: the docking mechanism includes a fixing sleeve 10, a first fixing hole 11, a second fixing hole 12, a fixing bolt 13 and a fixing nut 14, the fixing sleeve 10 is sleeved on the surface of the end of the transverse steel bar 3, the surface of the fixing sleeve 10 is provided with a first fixing hole 11, and the surface of the fixing sleeve 10 is provided with a second fixing hole 12.

[0033] During specific use, the transverse reinforcement bars 3 of two other concrete walls 1 are connected, so that the two concrete walls 1 can be more stable.

[0034] Preferably, a fixing bolt 13 penetrates the first fixing hole 11 , a fixing nut 14 is sleeved on the surface of the fixing bolt 13 , and the fixing bolt 13 and the fixing nut 14 are threadedly connected.

[0036] Working principle: When sound waves pass through the concrete shear wall, they first pass through the gypsum board 9, the slurry layer 8 and the hanging mesh 7. When the sound waves pass through the filler 6, the filler 6 can absorb part of the sound waves. Then, when the sound waves pass through the reflective wall brick 5, the smooth inner groove of the reflective wall brick 5 can reflect the sound waves. The reflected sound waves can be absorbed again by the filler 6. At the same time, the unreflected sound waves penetrate the reflective wall brick 5. When this part of the sound waves passes through the sound-absorbing concrete layer 4, the sound-absorbing material contained in the sound-absorbing concrete layer 4 can absorb the sound. In this way, most of the sound waves can be blocked, thereby greatly improving the sound insulation effect of the concrete shear wall.

[0037] When two concrete shear walls are spliced, firstly, the fixing sleeve 10 is sleeved on the surface of the transverse reinforcement 3 inside the other concrete wall 1, then the fixing bolt 13 is passed through the first fixing hole 11 and the second fixing hole 12, and then the fixing nut 14 is sleeved on the surface of the fixing bolt 13 and rotated, so that the transverse reinforcement 3 of the two concrete walls 1 can be connected, and finally concrete mud is injected, so that the concrete mud will be more stable after solidification.
