Abstract

The application discloses a foam concrete cored concave-convex building block, which belongs to the field of building materials. According to the utility model, a concrete hollow building block is made to be concave-convex, foam concrete is poured into a cavity of the building block, and a composite solid-structure heat-insulation building block is formed, therefore, the utility model solves the problems that the existing concrete hollow building blocks have cold bridge and poor sound insulation performance and a wall body has low stability because of too small bonding surfaces between the building blocks. The foam concrete cored concave-convex building block is used for building infilled walls of framework-structure buildings or bearing walls of residential buildings with less than six floors.

Description

Foam concrete adds the concavo-convex building block of core pattern

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, influences 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 adhesion strength and body of wall soundproof effect between the adiabatic building block simultaneously, its technical scheme is as follows:

1, concrete hollow block is made concaveconvex shape (seeing accompanying drawing 1), be referred to as the concave-convex concrete hollow block, i.e. building block one end is a spill, and a groove is arranged, and the other end is a convex, and a plush copper is arranged.So just make heat transfer distance in building block termination prolong greatly, building block termination cold bridge is eliminated.

2, with the concave-convex concrete hollow block as a housing, in its cavity, build foam concrete (seeing accompanying drawing 1) and maintenance, make its sclerosis, form compound solid type structure, be named as foam concrete and add the concavo-convex building block of core pattern.

3, this application product can be used for building by laying bricks or stones the infilled wall of frame structure building, also can be used to build 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 slurry surface of the application's product is exactly the end face of whole building block, its mortar bonding plane is far longer than concrete hollow block, the therefore body of wall of building by laying bricks or stones with it, and its stability and shear strength are far longer than concrete holllow building block wall, and be 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 the body of wall soundproof effect much larger than concrete hollow block, and also apparently higher than solid sintered clay brick body of wall.

The specific embodiment

Select for use the C20 pea gravel concreten to make building-block shell, housing wall thickness 30mm, shape and size such as Fig. 7, Fig. 8, Fig. 9 and shown in Figure 10, reach when building intensity (as 15MPa) by laying bricks or stones in the building-block shell maintenance, in its cavity, build foam coagulation scholar again, and maintenance reaches the intensity of building requirement by laying bricks or stones, promptly can be used to build a wall.It is built plan view by laying bricks or stones and sees Fig. 5, builds elevation by laying bricks or stones and sees Fig. 6.

Claims

1. foam concrete adds the concavo-convex building block of core pattern, it is characterized in that at one end building foam concrete for the spill opposite end is in the cavity of concrete hollow block of convex.
