Abstract

The utility model discloses a sandwich type groove heat-insulating building block which belongs to the field of building materials, wherein a concrete hollow building block is manufactured into groove-shaped, and foam concrete is poured in a cavity thereof to form a compound and solid structural heat-insulating building block, thereby solving the problems that because a cold bridge exists in the concrete hollow building block at present, the heat preserving and heat insulating effects are poorer, the sound insulating performance is poor, and the wall body stability is poorer due to the too small bonding surface between the building blocks and the like; the sandwich type groove heat-insulating building block is used for building the filling walls of frame-structured buildings or the bearing walls of lower than six stories of residential buildings.

Description

Add the adiabatic building block of core pattern groove

Technical field

The application belongs to constructional materials.

Background technology

Domestic widely used concrete hollow block all is a rectangular shape at present, the cavity is big, the porosity height, compare with solid sintered clay brick, its deadweight obviously reduces, and the heat insulating effect of the body of building a wall also obviously improves, but, there are three big shortcomings in this concrete hollow block, and the one, there is cold bridge in the building block termination, makes that the energy-saving effect of body of wall is not ideal enough; The 2nd, because the cavity is big, cause the slurry surface significantly to reduce, make that the adhesion strength between the neighbouring building block obviously descends, thereby cause the shear strength of body of wall significantly to reduce that the stability of body of wall is not high; The 3rd, soundproof effect is poor, reduces quality of life.Therefore, the needs design is a kind of can eliminate building block termination cold bridge, can improve the adiabatic building block of soundproof effect during Datong District, slurry surface again.

Summary of the invention

The objective of the invention is to eliminate adiabatic building block termination cold bridge, improve soundproof effect, strengthen the slurry surface of adiabatic building block simultaneously, technical scheme is as follows:

1, concrete hollow block is made groove shaped,, in its cavity, build foam concrete and maintenance sclerosis again, form the building block of compound solid construction type according to this as a shell.Because foam concrete has good heat insulating function, add core pattern groove thermal insulation building block so its building block is named as.

2, add the adiabatic building block of core pattern groove as shown in Figure 1, its auxiliary specification building block as shown in Figure 2, for L shaped.

What 3, add the adiabatic building block of core pattern groove builds plan view by laying bricks or stones as shown in Figure 3.As can be seen from Figure 3, with the body of wall that adds the adiabatic concrete block masonry of core pattern groove, heat transfer distance in building block termination prolongs greatly, and building block termination cold bridge is eliminated.

What 4, add the adiabatic building block of core pattern groove builds elevation by laying bricks or stones as shown in Figure 4.As can be seen from Figure 4, with the body of wall that adds the adiabatic concrete block masonry of core pattern groove, its horizontal mortar joint is the full type in plane, and the slurry surface is the same with other solid blocks, thereby has improved the stability and the shear strength of body of wall.

5, this application product can be used for building by laying bricks or stones the infilled wall of frame structure building, also can be used for building by laying bricks or stones the load bearing wall of residential building below six layers.

The application has following good effect:

(1) improves the body of wall energy-saving effect

With the body of wall that the application's product is built by laying bricks or stones, owing to eliminated the cold bridge of concrete hollow block and the heat convection in the concrete hollow block cavity, the energy-saving effect of body of wall significantly improves.

(2) improve wall stability

Because the area of the slurry surface of the application's product is exactly the area of whole building block end face, its mortar bonding plane is far longer than concrete hollow block, therefore the body of wall of building by laying bricks or stones with it, its stability and shear strength are far longer than concrete hollow block, identical with solid block, simultaneously because foam concrete volume density is very little, so, with the body of wall that it is built by laying bricks or stones, it from the increase of anharmonic ratio concrete holllow building block wall seldom.

(3) improve the body of wall soundproof effect

The solid construction that the application's product is special makes that its soundproof effect is much bigger more than concrete hollow block, and also apparently higher than solid clay brick.
