Environment-friendly heat insulation and sound insulation compound brick

Abstract

The invention relates to an environment-friendly heat insulation and sound insulation compound brick which comprises a heat insulation and sound insulation layer, a first brick layer and a second brick layer. The heat insulation and sound insulation layer is respectively provided with at least one group of first longitudinal and transverse trenches and at least one group of second longitudinal and transverse trenches on the first side surface and the second side surface, and the positions of the first and the second longitudinal and transverse trenches are mutually staggered; the first brick layer is integrally formed and combined on the first side surface of the heat insulation and sound insulation layer and fully filled in the at least one group of the first longitudinal and transverse trenches; the second brick layer is integrally formed and combined on the second side surface of the heat insulation and sound insulation layer and fully filled in the at least one group of the second longitudinal and transverse trenches; and the thickness of the second brick layer is greater than that of the first brick layer.

Description

technical field [0001] The invention relates to a hollow brick structure, in particular to an environmentally friendly insulation which can be made of environment-friendly materials, and has a heat and sound insulation layer between two brick layers, and is suitable for wall construction (outer walls or indoor partition walls). Thermal and sound-insulating composite bricks can not only effectively cut off the heat bridge (heat conduction path) and sound bridge (sound conduction path) to give better sound insulation and heat insulation performance, but also have light weight, high hardness, environmental protection, economy and easy masonry, etc. advantage. Background technique [0002] In terms of existing wall construction, the use of bricks is one of the most commonly used methods. When using bricks to build walls, in order to achieve thermal insulation and cold resistance performance, foam boards (such as expanded polystyrene boards) are usually attached to the walls mad...

AI Technical Summary

Problems solved by technology

However, in order to maintain the structural strength of the overall wall, the size of the cavity inside the hollow brick must be limited

In addition to the impact of the cavity setting restrictions on the thermal insulation and cold resistance effect, when the wall is built, there are still many thermal bridges between the hollow brick body and the hollow bricks, which greatly reduces the thermal insulation and cold resistance effect.

[0007] In addition to poor thermal insulation and cold resistance, the walls built with hollow bricks still have two disadvantages.

First, the structural strength is insufficient; if a wall made of hollow bricks is used in a high-rise building, its structural strength will not be enough to resist violent shaking caused by an earthquake, so it is limited in practical use

Second, hollow bricks are prone to cracks after being used for a period of time, so hot air and water vapor will flow through the cracks inside and outside the house, which will completely lose the ability of heat preservation and cold resistance
