Abstract

The utility model discloses a green and environment-friendly sound-absorbing and noise-reducing building block, comprising a brick body (1) with transversing holes (2); and foam concrete is filled in at least one row of transversing holes (2) of the brick body (1); and the transversing holes (2) filled with the foam concrete are positioned at the two side edges or one side edge of the brick body (1). The middle of the brick body (1) is also provided with the transversing holes (2) which are arranged symmetrically and are filled with foam concrete. In the green and environmentally-friendly sound-absorbing and noise-reducing building block, the foam concrete has a half-closed hole type, thus having sound-absorbing performance with wider frequency, increasing the sound-absorbing performance of a wall body when being filled in the hollow building block in a composite manner, and further improving the weighted sound insulation index of airborne sound of the wall body. Simultaneously, since the holes on the brick body are not more, the self strength of the brick body is higher, the volume weight is light, and the manufacture is easy.

Description

A kind of environmental protection sound absorption reduction building block

Technical field

The utility model relates to a kind of a kind of building unit that is made of different materials.

Background technology

The solid block of the common usefulness of materials for wall commonly used at present, its principle is the effect that reaches noise reduction sound insulation by the unit weight that improves body of wall, the unit weight that doubles, air weighted sound reduction index could improve 3 to 5 decibels, along with building-block is widely applied highrise building, in order to improve its sound insulation value, usually the way of taking is to improve its hole ratio, but manufacturing technique requirent also improves when improving hole ratio, the production difficulty increases, the intensity of building block also reduces, and scrappage is multiplied.

The utility model content

The purpose of this utility model provides a kind of intensity height, environmental protection sound absorption reduction building block that soundproof effect is good.

Realize above-mentioned purpose by the following technical solutions, a kind of environmental protection sound absorption reduction building block comprises the brick body with horizontal perforation, it is characterized in that: be filled with foam concrete at least one horizontal row perforation of described brick body.

As further optimization, in order to improve soundproof effect, the described horizontal perforation that is filled with foam concrete is positioned at two sides or side of brick body.

The middle part of described brick body also has horizontal perforation symmetrically arranged, that be filled with foam concrete.

The concrete packed density of described horizontal perforation inner foam is less than 230kg/m ³

The beneficial effects of the utility model: thereby because foam concrete possesses the sound absorbing capabilities that semi-closure hole pass has the broad frequency, the composite filled sound absorbing capabilities that in building-block, increases body of wall, thereby the body of wall air weighted sound reduction index that obviously improves.Simultaneously, because the hole in the building block is not a lot, the intensity of building block self is higher, unit weight light, it is easy to make.

The specific embodiment

Below in conjunction with the drawings and specific embodiments the utility model is described further:

Embodiment 1: as shown in Figure 1, a kind of environmental protection sound absorption reduction building block comprises the brick body 1 with horizontal perforation 2, is filled with foam concrete in the whole horizontal row perforation 2 of one on the side of brick body 1, and the packed density of foam concrete is less than 230kg/m ³Build by laying bricks or stones in order if fill horizontal row perforation with the wide foam concrete of 40mm, but 45 decibels of this body of wall noise reductions.

Embodiment 2: as shown in Figure 2, as different from Example 1, two sides of brick body 1 all are filled with foam concrete, if fill, and build by laying bricks or stones in order with the wide foam concrete of 40mm, but 49 decibels of noise reductions.

Embodiment 3: as shown in Figure 3, as different from Example 2, the wide foam concrete lack of alignment of remaining some horizontal perforation 2 usefulness 40mm is filled on the brick body 1, but adopts 47 decibels of such masonry panel noise reductions.

Embodiment 4: as shown in Figure 4, as different from Example 2, the wide foam concrete of remaining some horizontal perforation 2 usefulness 40mm is arranged filling in order on the brick body 1, and is filled with horizontal perforation 2 symmetrical distributions of foam concrete.

Embodiment 5: as shown in Figure 5, as different from Example 1, the wide foam concrete lack of alignment of remaining some horizontal perforation 2 usefulness 40mm is filled on the brick body 1.

Though more than with specific embodiment the utility model has been done detailed explanation in conjunction with the accompanying drawings; but the structure of specific embodiment does not constitute restriction of the present utility model; those skilled in the art should learn; any variation or change in the utility model claim protection domain all are subjected to protection of the present utility model.
