Abstract

The utility model relates to a cement building block, which comprises a plastic foam layer made of plastic foam, and cement layers which are made of cement and rabbeted on the two sides of the plastic foam layer. The utility model has the advantages that: the plastic foam layer and the cement layers are combined, so that the building block has excellent heat insulation, sound insulation, waterproof performances and the weight of the building block is greatly reduced; and the cement layers are rabbeted on the plastic foam layer, thereby ensuring good compression resistant performance of the building block.

Description

A kind of cement block

Technical field

The utility model relates to building block, a kind of specifically cement block that is widely used in one-storey house, bottom building and highrise building.

Background technology

Along with the development of China's construction market, various in recent years New Building Materials constantly emerge.Country has put into effect some relevant encouragement policies in succession with each place government, advocates the energy-conservation New Building Materials of use in the middle of new building energetically.

At present, a lot of light-weight building building blocks on market, have been developed.Mainly contain hollow concrete block, big grey brick, mix earth hollow brick etc.Hollow concrete block adopts the hollow-core construction of up/down perforation, therefore the body of wall that uses this hollow concrete block to be built into also is the hollow-core construction of up/down perforation, though but the body of wall of this structure has certain intensity its poor-performing at aspects such as insulation, sound insulations, on market, can not get excellent popularization and use.Big grey brick weight is lighter, but compressive property is poor, the manufacturing cost height.Be and mix its weak point of earth hollow brick, soundproof effect, heat-proof quality is poor.

Along with improving constantly of Chinese economic development and living standards of the people, people more and more pay close attention to the heat insulation and soundproof effect of house when selecting house.Just need to select to have constructional materials well heat insulation, sound insulation value when therefore building a house, and building block is indispensable in a constructional materials important component part, develop lightweight for this reason and have good waterproof, novel building building block heat insulation and sound insulation value is extremely urgent.

The utility model content

The purpose of this utility model is to overcome the defective of above-mentioned building block, and a kind of cement block well heat insulation, sound insulation value that has is provided.

The following technical scheme of employing of the present utility model: a kind of cement block, it comprise the plastic foam layer made by plastic foam and by cement make, joggle is at the cement layer of described plastic foam layer both sides.

Aforementioned a kind of cement block is distributed with through hole in its cement layer, described through hole towards being parallel to above-mentioned plastic foam layer.

The both sides of above-mentioned plastic foam layer respectively have a swallow-tail form tenon shape projection and cement layer respectively to have a swallow-tail form tongue-and-groove corresponding with described swallow-tail form tenon shape projection.

By above-mentioned description to the utility model structure as can be known, compare, the utlity model has following advantage with prior art:

1) by the combination of cement layer and plastic foam layer, the single structure that has changed cement block has been guaranteed heat insulation, sound insulation, the water resistance of plastic foam building block and has greatly been alleviated the own wt of building block;

2) between cement layer and the plastic foam layer by the joggle combination, guaranteed that building block has the good pressure resistance energy;

3) described block structure is simple and meet the demand in current market.

The specific embodiment

The specific embodiment of the present utility model is described with reference to the accompanying drawings.

Embodiment one

With reference to Fig. 1.A kind of cement block, it comprises the plastic foam layer 1 made by plastic foam and makes, is fixed in the cement layer 2 of described plastic foam layer 1 both sides by cement that described cement layer 2 is fixed with the both sides joggle of plastic foam layer 1 respectively.

Referring to figs. 1 through Fig. 3.Each joggle one cement layer 2 of described plastic foam layer 1 both sides, described cement layer 2 is a solid construction.The both sides of plastic foam layer respectively are provided with a tenon shape projection 3; Cement layer is provided with a swallow-tail form tongue-and-groove 4, and the tenon shape projection 3 of plastic foam layer and the swallow-tail form tongue-and-groove on the cement layer 24 are corresponding mutually.For giving full play to the cement block superior function, must place perpendicular to horizontal plane with the plastic foam layer 1 of cement layer 2 joggles in use, thereby maximization realizes heat insulation, sound insulation, the waterproof effect of cement block.

Embodiment two

With reference to Fig. 4 and Fig. 5.The structure of present embodiment and embodiment one is basic identical, and both main distinctions are to be distributed with several through holes 5 on the cement layer 2 in the present embodiment, and through hole 5 towards being parallel to plastic foam layer 1.The cross sectional shape of above-mentioned through hole 5 is not limit, and can be a kind of in circle, rectangle, rhombus, the square etc., can be any combination of above-mentioned concrete shape yet.

Compare with embodiment one, the major advantage of present embodiment is also to have reduced the consumption of cement material greatly under the situation of not losing good resistance to compression, heat insulation, sound insulation, waterproof.Not only save resource but also alleviated the own wt of cement block, played the effect of killing two birds with one stone.

Building block is structure as a whole described in above-mentioned two embodiment, is not splicing structure, and the plastic foam layer promptly is combined among two cement layers in the forming process of building block.

Above-mentioned only is the specific embodiment of the present utility model, but design concept of the present utility model is not limited thereto, and allly utilizes this design that the utility model is carried out the change of unsubstantiality, all should belong to the behavior of invading the utility model protection domain.

Claims

1. cement block is characterized in that: it comprise the plastic foam layer made by plastic foam and by cement make, joggle is at the cement layer of described plastic foam layer both sides.

2. a kind of cement block as claimed in claim 1 is characterized in that: be distributed with through hole in the above-mentioned cement layer, described through hole towards being parallel to above-mentioned plastic foam layer.

3. a kind of cement block as claimed in claim 1 or 2 is characterized in that: the both sides of above-mentioned plastic foam layer respectively have a swallow-tail form tenon shape projection and cement layer respectively to have a swallow-tail form tongue-and-groove corresponding with described swallow-tail form tenon shape projection.
