Acid rain-resistant exterior wall brick for building

Abstract

The invention relates to an acid rain-resistant exterior wall brick for a building, which comprises a brick body A and a brick body B, wherein the brick body A and the brick body B are symmetrical instructure, and the brick body A and the brick body B are provided with a sound insulation layer therebetween; the brick body A and the brick body B are provided with grooves, and the sides, opposite to the grooves, on the brick body A and the brick body B are provided with convex strips adapted to the grooves, the middles of the brick body A and the brick body B are hollow, and the brick body A and the brick body B are provided with ribs; the hollow portions in the middles of the brick body A and the brick body B are filled with a heat insulating filling agent; the thickness of each of the brick body A and the brick body B is 30 mm; the thickness of the sound insulation layer is 40 mm; compared with the prior art, the acid rain-resistant exterior wall brick of the invention has the beneficial effects that the invention provides an acid rain-resistant exterior wall brick for the building, and the heat insulating filling agent is charged between brick bodies, which plays a role of heat insulation, and the brick bodies are provided with the grooves and ribs, which plays a role of good positioning; the heat insulation and noise reduction effects are good, simple construction and high construction efficiency are realized.

Description

technical field [0001] The invention relates to the field of building materials, in particular to an acid rain-resistant exterior wall brick for buildings. Background technique [0002] Brick is a cuboid stone used for building walls. It is fired with mud and is mostly red. It is commonly known as "red brick", and there are also blue "green bricks". The size of the Chinese standard clay brick is 240×115×53mm. The purpose of this size is to ensure that the ratio of the length, width and height of the brick is 4:2:1 (including the mortar joint width of 10mm). The thickness of a brick wall is often called in multiples of bricks. Since the length of a brick is 240mm, a wall with a thickness of one brick is also called a "two-four" wall, and a wall with a thickness of one and a half bricks is also called a "three-seven" wall. The half-brick wall is also called the "first and second" wall. Artificial small blocks for construction are divided into fired bricks (mainly clay bricks...

AI Technical Summary

Problems solved by technology

These wall structures all occupy a large space, and at the same time, the insulation effect is not ideal, the construction is complicated and the cycle is long, the wall is greatly affected by the climate, and the cost is high.
