Concrete energy-saving hollow brick

Abstract

The invention relates to a concrete energy-saving hollow brick. The concrete energy-saving hollow brick comprises building blocks, wherein brick holes are formed on the building blocks; the building blocks comprise a main block and more than two auxiliary blocks; three rows of rectangular holes are formed in the length direction of the building blocks uniformly; the number of the rectangular holes is 9; the rectangular holes are through holes or blind holes; more than one groove is formed on the four sides in the length direction of the building blocks uniformly; and the length of each auxiliary block is 1 / 2 to 3 / 4 of that of the main block. The widths of a bedding face and a top face of the concrete energy-saving hollow brick are the same as the thickness of a wall body, so the compressive resistance and the shear resistance are enhanced, the bonding strength of the wall body is high, and the fundamental problem of generating cracks of the wall body is solved. The cost of the concrete energy-saving hollow bricks per square meter is about 15 percent lower than that of the conventional novel wall body materials; secondary decoration can be directly performed after the wall body is built, without interface treatment and outer wall heat preservation; the construction time is shortened; and compared with the comprehensive cost of the conventional product wall body, the comprehensive cost of the wall body is reduced by over 35 percent.

Description

technical field [0001] The invention belongs to the technical field of concrete hollow blocks (bricks) for building, and in particular relates to a concrete energy-saving hollow brick. Background technique [0002] After decades of domestic and foreign a large number of experimental research and practical use, concrete hollow blocks (bricks) have relatively mature production and application technology. The currently commonly used concrete small hollow blocks and concrete porous bricks are mostly cement products with upper and lower through holes, semi-blind holes or fully sealed bottoms, which will cause the masonry mortar to have a small fullness and small bonding surface during masonry, which will affect the compression resistance. The shear strength is easy to cause cracks in the wall. Contents of the invention [0003] In order to solve the problems existing in the existing concrete small hollow blocks and concrete porous bricks that the masonry mortar fullness is sma...
