Load-bearing concrete perforated brick

Abstract

A load-bearing concrete perforated brick comprises a brick body, and two through holes are formed in the brick body axially; the two ports of the through holes are axially located in the two end facesof the brick body separately, and the two through holes are formed in parallel; the sum of the cross sectional areas of the two through holes is larger than one half of the area of the axial end faceof the brick body, and a spacing area is formed between the two through holes; the end face area of the spacing area is smaller than the cross sectional area of the through holes; and the sizes and shapes of the two through holes are identical. The load-bearing concrete perforated brick has the characteristics of excellent thermal insulation property, good cold-proof performance, and obvious heatand sound insulation.

Description

technical field [0001] The invention belongs to the technical field of building materials, in particular to a load-bearing concrete porous brick. Background technique [0002] At present, the traditional red brick is a solid brick body, and the solid brick is generally made of clay, shale and fly ash as the main materials, which will consume a lot of soil resources, and the density of the brick body is relatively high, and the same building volume needs to be consumed More brick bodies, resulting in low construction efficiency. Simultaneously because the thermal conductivity coefficient of solid brick is bigger, therefore, the heat insulation effect of the building body that uses above-mentioned solid brick is poorer. [0003] Porous bricks refer to clay, shale, and fly ash as the main materials, and the brick body is shaped and baked. The porosity is not less than 15% to 30%. The hole type is round or non-round. The size of the hole is Small but large in quantity, this pr...

However, the current perforated bricks are provided with additional smaller holes, which are usually blind holes, but it is found in the actual use process that its performance cannot meet the needs of use
