Multilayer heat-insulating and sound-insulating self-insulation hollow brick

Abstract

A multilayer heat-insulating and sound-insulating self-insulation hollow brick comprises an upper-layer overlapped surface, a lower-layer overlapped surface, an exposed surface and an abutting surface, wherein insulating sound-insulating cavities and vertical pressure bearing rib plates are mutually arranged on the abutting surface alternatively; and the insulating sound-insulating cavities are vertically distributed in the thickness direction of the brick body at equal space. The multilayer heat-insulating and sound-insulating self-insulation hollow brick has enough pressure bearing strength and favorable heat-insulating and sound-insulating performances as well as low integrated cost and remarkable material and energy saving effects; no heat insulating bar is needed to be inserted into a material saving hole; and the mortar amount of the multilayer heat-insulating and sound-insulating self-insulation hollow brick for building a wall with mud is the same as that of a solid brick.

Description

Technical field: [0001] The invention relates to a building component, in particular to a porous heat insulating brick. Background technique: [0002] In the existing technology, in order to meet the new requirements of energy saving and material saving, wall reform offices have been established in various places, focusing on promoting energy-saving and material-saving porous insulation bricks. The country has also issued corresponding incentive policies, so people invest a lot in porous insulation bricks According to the research and test, many schemes have been introduced. The porous insulation bricks that have been widely used have a rectangular parallelepiped structure. The standard size is 240mm in length, 115mm in width, and 90mm in thickness. Composed of butt joint surfaces, there are neatly arranged material-saving holes on the upper and lower laminated surfaces of the brick body. The size and shape of all material-saving holes are exactly the same, and they are arra...

AI Technical Summary

Problems solved by technology

Although this kind of porous insulation brick has simple structure, strong pressure bearing capacity, high porosity ratio, light weight and obvious material saving effect, it also has certain thermal insulation performance and is convenient to process, but it is very inconvenient to use. Insulation strips are inserted in the holes, and the amount of mortar is increased, and the overall cost is too high

In many engineering constructions, people usually use pure hollow bricks without insulation strips instead. In this way, the thermal conductivity is too high, and the thermal insulation and sound insulation effects are not ideal.

Since the material-saving holes are set on the upper and lower laminated surfaces, when building walls with such hollow bricks, cement mortar must be added between the upper and lower bricks, and the mortar will fall into the material-saving holes, which not only consumes a lot of mortar, increases costs, but also affects Insulation and sound insulation effect of the whole wall

In order to overcome this defect, a porous insulation brick is disclosed in Chinese utility model patent ZL2009200383446, which changes the material-saving holes on the upper and lower laminated surfaces into blind holes, and inserts insulation strips on the side close to the exposed surface. The sound insulation effect has improved, but the production of blind hole bricks has become more difficult, and insulation strips must be inserted in some blind holes, and the overall cost is still too high
