Concrete block

Abstract

The invention discloses a concrete block. The cross section of the concrete block is square; a rib plate is vertically arranged in the center of the square; the middle part of the upper side of the square is raised; the corresponding part of the lower side of the square is recessed; the height of the raised part and the height of the recess are the same. The concrete block is made of common concrete, high in building efficiency, low in cost and long in service life and can be subjected to dry masonry, the materials are readily available, the strength can reach the current national standard requirements, and the heat loss is low; concrete blocks are meshed and locked to be built from top to bottom, and thus the integrity is high.

Description

technical field [0001] The invention relates to the technical field of building materials, in particular to a concrete block. Background technique [0002] Concrete blocks are the most commonly used and important components in the field of building materials. A significant disadvantage of building walls made of concrete blocks is that the heat loss of the walls is large, which is not conducive to energy saving; especially in cold regions, the heat loss is greater , It is often necessary to install thermal insulation materials on the outside of the wall, but this method has some disadvantages: firstly, its fire resistance is poor, easy to catch fire, secondly, its durability is low, the external paint is easy to fall off, and the construction and maintenance costs are also high. Contents of the invention [0003] Aiming at the deficiencies of the prior art, the present invention proposes a concrete block with small heat loss, and the block is consistent from top to bottom a...
