Embedded heat-insulating brick

Abstract

The invention provides an embedded heat-insulating brick which is of a three-layer embedded structure. Concrete outer layers are arranged on two side faces of the heat-insulating brick, a heat-insulating interlayer is arranged between the concrete outer layers, both length and height of each concrete outer layer are larger than those of the heat-insulating interlayer in the middle, so that both longitudinal section and cross section of the heat-insulating brick are H-shaped; a trapezoidal embedding groove with a wider opening and a narrower bottom is formed in the center line of each of the upper surface and the rear surface of each concrete outer layer, and a trapezoidal convex rib corresponding to the corresponding trapezoidal groove in position is arranged on each of the lower surface and the front surface of each concrete outer layer. The embedded heat-insulating brick has the advantages of light weight, high strength and good heat-insulating performance, and is convenient for leveling and aligning in the process of bricklaying, so that construction operation efficiency and wall bricklaying quality are improved; two outer surfaces of the heat-insulating brick are flat, smooth and clean, and decorating bricks can be pasted or whiting can be performed directly without covering a cement face on the surface of a wall after bricklaying, so that building cost is saved greatly.

Description

technical field [0001] The invention belongs to the technical field of building materials, and in particular relates to a built-in thermal insulation brick used for various building masonry. Background technique [0002] There are many types of building bricks, mainly including clay bricks, aerated blocks, shale bricks, coal gangue bricks, fly ash bricks, concrete bricks and lime sand bricks according to their materials. According to the molding method, it is divided into fired bricks (mainly clay bricks) and non-fired bricks (such as lime sand bricks, concrete bricks, fly ash bricks, etc.). According to the porosity, it is divided into solid brick, porous brick and hollow brick. [0003] Clay bricks are made from local materials, cheap, durable, and have the characteristics of fire prevention and moisture absorption. They are the most widely used masonry bricks in civil construction. Because clay bricks have the defects of small bricks, heavy weight, and high soil consump...

AI Technical Summary

Problems solved by technology

At present, most of the building bricks commonly used are right-angled hexagonal cuboids. It is difficult to align them during masonry, and it is difficult to grasp the levelness and verticality. Moreover, after the wall is built, it is still necessary to apply cement on both sides of the wall. In order to increase the overall strength of the wall and carry out subsequent construction, so the requirements for masonry are high, labor-intensive and time-consuming, and increase the consumption of cement covering

[0004] In recent years, there is a new demand for the thermal insulation performance of the wall in the cold northern regions, so more and more houses are used for external wall insulation, which not only increases the extra cost, but also the current external wall insulation boards Light, but soft texture, afraid of collision, limited service life
