Abstract

The utility model discloses a composite concrete self-heat-insulating building block. The building block comprises a building block body, wherein three rows of strip-shaped slots penetrating through the upper and lower end surfaces of the building block body are formed in the building block body; the strip-shaped slots in the first and third rows are three-section slots; the strip-shaped slots in the middle row are integral through slots in the horizontal direction, and are filled with rigid polyurethane foam to form a heat-insulating layer. The building block is reasonable in structure, and the rows of strip-shaped slots are arranged in the building block body at equal intervals; the hollow structure is simple and reasonable, light in deadweight, and easy to form by pressing; the efficient polyurethane organic heat-insulating layer and a dual sound-insulating structures are arranged in a staggered manner, so that the gap is effectively increased, and the heat-insulating and sound-insulating effects are greatly improved.

Description

Composite self-heat-insulation concrete building block

Technical field

The utility model relates to a kind of composite self-heat-insulation concrete building block.

Background technology

Brick is the material of main part of building a wall, and its quality directly affects the important indicators such as the sound insulation of built a house room, insulation, waterproof, compressive strength.Traditional solid clay brick is all good products of the quality index such as a kind of apparent density, compressive strength, but insulation, sound insulation value are relatively poor, has larger gap ，Xian Jibei government explicit order limit production with modern housing construction standard.In addition, solid clay brick is produced to be needed to consume a large amount of clays, and brickmaking enterprise continuous production need to fetch earth in a large number, must consume farmland, location, soil belongs to non-renewable resources, is the space that people depend on for existence, so restriction solid clay brick is produced, is right, correct.

At present, on market, oneself substitutes solid clay brick by concrete brick, clinker brick, although modern brickmaking oneself accomplish not consume clay, solid construction is unreasonable, quality index does not reach expection.

Summary of the invention

It is a kind of rational in infrastructure that the purpose of this utility model is to provide, and heat preservation and soundproof is effective, from the composite self-heat-insulation concrete building block of heavy and light.

Technical solution of the present utility model is:

A kind of composite self-heat-insulation concrete building block, comprise building block body, it is characterized in that: the rectangular groove that three rows are run through upper and lower end face is set on building block body, the rectangular groove that is positioned at first and third row is three sections of groove, a middle row's rectangular groove is the integral channel that a left and right connects, and in middle platoon leader's bar groove, filled polyurethane rigid foam forms thermal insulation separation thermosphere.

The connector of joint block body upper and lower part is set in a middle row's rectangular groove.

Described first and third row's rectangular groove is up big and down small cone-shaped cavity.

The utility model is rational in infrastructure, the equidistant rectangular grooves of built-in many rows, this kind of hollow-core construction be simple, rationally, from heavy and light, compressing easily; The setting alternate with dual sound-insulating structure of the efficient organic heat-insulating layer of polyurethane, effectively increases spacing, has greatly improved insulation and soundproof effect.

Accompanying drawing explanation

Below in conjunction with drawings and Examples, the utility model is described in further detail.

Fig. 1 is the bottom surface structure schematic diagram of an embodiment of the utility model.

Fig. 2 is the A-A sectional drawing of Fig. 1.

The specific embodiment

A kind of composite self-heat-insulation concrete building block, comprise building block body 1, three rows are set on building block body and run through the rectangular groove of upper and lower end face, the

rectangular groove

2,4 that is positioned at first and third row is three sections of groove, a middle row's rectangular groove is the integral channel that a left and right connects, and in middle platoon leader's bar groove, filled polyurethane rigid foam forms thermal insulation separation thermosphere 3.

The connector 5 of joint block body upper and lower part is set in a middle row's rectangular groove.

Described first and third row's rectangular groove is up big and down small cone-shaped cavity, and the demoulding when being conducive to compression molding of this kind of structure also reduces falling into of mortar while building a wall, meanwhile, and the dual sound-insulating structure of the vacant formation of rectangular groove of this position.

Claims

1. a composite self-heat-insulation concrete building block, comprise building block body, it is characterized in that: the rectangular groove that three rows are run through upper and lower end face is set on building block body, the rectangular groove that is positioned at first and third row is three sections of groove, a middle row's rectangular groove is the integral channel that a left and right connects, and in middle platoon leader's bar groove, filled polyurethane rigid foam forms thermal insulation separation thermosphere.

2. composite self-heat-insulation concrete building block according to claim 1, is characterized in that: the connector that joint block body upper and lower part is set in a middle row's rectangular groove.
