Hollow brick with sound insulation and heat insulation functions

Abstract

The invention discloses a hollow brick with sound insulation and heat insulation functions. The hollow brick with the sound insulation and heat insulation functions comprises an inner brick body and an outer brick body; a sound insulation layer is arranged between the inner brick body and the outer brick body; a hollow hole is formed in the inner brick body; the hollow hole is a rectangular long straight oval hole with a cross section and with the upper end and the lower end combined with semicircles; the hollow hole transversely penetrates through the inner brick body; and a heat insulation material capable of isolating heat transfer is arranged in the hollow hole. The hollow brick is divided into the inner brick body and the outer brick body, and the sound insulation layer is arranged between the inner brick body and the outer brick body, so that noises can be effectively isolated; in addition, the semi-circular arch structures at the upper end and the lower end of the long straightoval hole can bear large gravity, and materials needed for manufacturing the hollow brick can be saved to the maximum extent on the premise that the supporting strength of the hollow brick is not affected; and meanwhile, the heat insulation material capable of isolating heat transfer is arranged in the hollow brick, so that heat transfer can be effectively isolated, and the hollow brick has the beneficial effects of heat preservation and heat insulation.

Description

technical field [0001] The invention relates to a hollow brick, in particular to a hollow brick with sound and heat insulation functions. Background technique [0002] Hollow bricks are divided into cement hollow bricks, clay hollow bricks, and shale hollow bricks; hollow bricks are the main wall materials commonly used in the construction industry in recent years. Due to their advantages such as light weight and low consumption of raw materials, they have become the first product recommended by the national construction department. Like red bricks, the common raw materials for hollow bricks are clay and cinder ash, and the general specification is 390×190×190mm; the percentage of the total hole area of ​​hollow bricks in the area of ​​the bricks is called the porosity of hollow bricks, which should generally be 15%. Above; compared with solid bricks, hollow bricks can save a lot of land, soil and brick-burning fuel, reduce transportation weight, reduce labor intensity durin...

AI Technical Summary

Problems solved by technology

[0003] Hollow bricks are light in weight, high in strength, good in thermal insulation, sound insulation and noise reduction, environmentally friendly and pollution-free, and are ideal filling materials for frame structure buildings; however, existing hollow bricks have certain shortcomings, such as existing hollow bricks do not have good sound insulation Heat insulation function, so that when hollow bricks are used in some special positions, they do not have the function of sound insulation and heat insulation, so that they cannot meet the needs of different positions, further reducing the practicability and scope of use of hollow bricks; in addition, the hollow bricks of the prior art The hollow holes in the hollow bricks cannot reach the best porosity, and a certain amount of raw materials need to be wasted when manufacturing hollow bricks
