Water resistance and thermal insulation outer wall building block with water drainage structure

Abstract

The invention provides a water resistance and thermal insulation outer wall building block with a water drainage structure. The water resistance and thermal insulation outer wall building block comprises a cuboid polystyrene core mold. Six thin reinforced concrete layers are poured on the six surfaces of the polystyrene core mold correspondingly to form the outer wall building block filled with thermal insulation materials; and the upper edge of the outer wall face of the outer wall building block is concaved downwards to form a notch, the lower edge of the outer wall face of the outer wall building block is provided with a lower buckle extending downwards, and the lower buckle is in overlap joint with a notch in the upper end of an adjacent outer wall building block under the outer wall building block, so that a horizontal gap between the two vertically adjacent outer wall building blocks is sealed. Vertical grooves are formed in the left side wall and the right side wall of the outer wall building block correspondingly, and the vertical grooves and vertical grooves formed in the side walls of the left and right adjacent outer wall building blocks form vertical water drainage hole passages. The outer wall building block is provided with the water drainage structure and is capable of draining water leaked from the outer wall face through the water drainage hole passages; and the outer wall building block has the advantages of being light in weight, good in water resistance and thermal insulation effect, simple in operation, low in cost, low in brickwork labor and the like.

Description

technical field [0001] The invention relates to the technical field of new building materials, in particular to a waterproof and heat-retaining outer wall block with a drainage structure. Background technique [0002] The external wall masonry blocks of buildings usually require light weight, high strength, heat preservation, fire prevention, rainwater penetration and immersion resistance, etc. However, the existing wall materials are difficult to meet the above requirements. For example, the existing external wall blocks usually use foaming materials to be evenly mixed in the concrete, and then the forming blocks are poured. Although this type of block can improve the thermal insulation performance of ordinary blocks to a certain extent, the waterproof performance of this type of block is poor. The walls receive rainwater penetration and soaking. In addition, this kind of external wall blocks is relatively rough, and when building masonry, it requires a lot of labor and m...

AI Technical Summary

Problems solved by technology

However, the existing wall materials are difficult to meet the above requirements. For example, the existing external wall blocks are usually uniformly mixed with foamed materials in concrete, and then poured into the formed blocks.

Although this type of block can improve the thermal insulation performance of ordinary blocks to a certain extent, the waterproof performance of this type of block is poor. Walls receive rainwater penetration and soaking

In addition, this kind of external wall blocks are relatively rough. When building masonry, a lot of labor and materials are used, and wet work on site is required.
