Embodiment Construction

[0038] The specific embodiment of the present invention is shown in the accompanying drawings. The interlocking sound-absorbing brick is composed of a side vertical plate 1, a back plate 2, a bottom plate 3 and a central vertical plate 4; side vertical plates 1 are processed on both sides of the bottom plate 3, A central vertical panel 4 is processed in the middle, and a back panel 2 is processed at the rear; two side vertical panels 1 , a central vertical panel 4 and a back panel 2 are processed into an "E" shape, forming two Helmholtz cavities 9 . Base plate 3 and central vertical plate 4 are longer than side vertical plate 1 and are 5mm. Boss 5 is processed on the top of side vertical plate 1, back plate 2 and central vertical plate 4, and boss 5 is “E” type. A decorative groove 6 is processed on the outer side of the upper part of the side vertical plate 1 . Central vertical plate 4 is processed into " T " font. The upper part of the central vertical plate 4 is processed...

Abstract

The invention provides an embedded and locked type noise-absorbing brick which relates to a brick used for construction, in particular to an acoustic shielding wall used for both sides of a road, which also can be used for regulating indoor acoustic environment. The embedded type noise-absorbing brick comprises side upright plates, a back plate, a bottom plate and a central upright plate, whereinboth sides of the bottom plate are processed with the side upright plates, the middle is processed with the central upright plate, and the back part is processed with the back plate; the two side upright plates, the central upright plate and the back plate are processed into an E shape and form two helmholtz hollow cavities. The invention has the advantages of novel structure, low cost, convenient construction, labor saving, good noise-absorbing effect, easy recovery and the like, so that the invention belongs to a novel embedded and locked type noise-absorbing brick integrating economy and practicability into a whole.

Description

technical field [0001] The interlocking sound-absorbing brick of the present invention is a building brick, especially used for sound screen walls on both sides of the road, and can also be used to adjust the indoor acoustic environment. Background technique [0002] The traditional sound-absorbing bricks currently used are usually hexahedral hollow bricks with five sides closed and one side open, and sound-absorbing vertical grooves left on the side. During construction, the upper and lower sides are relatively masonry to form a Helmholtz cavity. But in fact, the application of our traditional sound-absorbing bricks is very small. There are mainly the following limitations: [0003] 1. Acoustic design requires different absorption frequencies. Manufacturers of traditional sound-absorbing bricks need to process multiple sets of molds. The cost of molds is expensive, and the amount of traditional sound-absorbing bricks is not large. Manufacturers of hollow bricks are unwilli...
