H-shaped cross bore chain-type concrete block

Abstract

The invention provides an H-shaped cross bore chain-type concrete block, comprising a hollow cuboid I, a hollow cuboid II and a connecting block, wherein the hollow cuboid I is connected with the hollow cuboid II through the connecting block. Bosses are arranged on the middle parts of the upper ends of the hollow cuboid I and the hollow cuboid II while grooves are arranged on the middle parts of the lower ends of the hollow cuboid I and the hollow cuboid II; the bosses are correspondingly engaged with the grooves when the upper and lower concrete blocks are laid; and a heat insulating material is filled in a hollow cavity formed by laying the hollow cuboid I, the hollow cuboid II and the upper and lower concrete blocks. Masonry mortar or fine aggregate concrete is filled in a masonry gap between the upper and lower concrete blocks, so that direct force transmission of the concrete blocks can be achieved through four vertical ribs of the blocks to meet the demand on bearing blocks. The H-shaped cross bore chain-type concrete block disclosed by the invention solves the problem of a thermal bridge, and is small in thermal loss of wall body and good in heat insulating effect and fire preventing effect; when the blocks are laid, the upper and lower blocks are engaged with each other to accomplish chain-type masonry, and therefore, the block disclosed by the invention has good integrity and anti-seepage property, is high in bearing capacity and reduces the cost while the quality of a brickwork is improved.

Description

technical field [0001] The invention relates to an H-shaped cross-hole interlocking concrete block, which belongs to the field of building materials. Background technique [0002] In the field of building materials, concrete blocks are the most commonly used and extremely important constituent units. However, the obvious disadvantage of building walls made of ordinary interlocking concrete blocks with horizontal holes is that the heat loss of the walls is large, which is not conducive to energy saving. . Especially in severe cold regions, the heat loss is greater. In order to keep warm, it is often necessary to attach insulation materials to the outside of the wall. However, this method also brings two prominent disadvantages: one is that the commonly used external insulation materials have poor fire resistance and are prone to fire; the other is that the durability is poor, the external paint is easy to fall off, and the construction and maintenance costs are relatively hi...

AI Technical Summary

Problems solved by technology

[0003] In addition, ordinary interlocking concrete blocks with horizontal holes only have two vertical ribs for force transmission, and the bearing capacity is low. They are only suitable for filling walls and cannot be used for load-bearing walls of masonry structures.
