Abstract

The utility model provides a perforated brick formed by sintering shale tailings. The specification of the perforated brick is 190*190*90; a plurality of square holes are formed on the brick body; the specification of the central square hole in the center of the brick body is 40*36; and a plurality of square holes which are smaller than the central square hole are symmetrically distributed at the periphery of the central square hole in such a manner that the center of the central square hole serves as a benchmark. As the square holes which are smaller than the central square hole are symmetrically distributed at the periphery of the central square hole in such a manner that the center of the central square hole serves as the benchmark, the utility model has the advantages that the structure of the brick body is compact; the phenomenon that strength differences among different parts of the brick body are over large because holes on the brick body are not distributed uniformly is eliminated; and the void ratio can be 33.5%. Therefore, the utility model further has the advantages that the weight of the brick body is relatively light; the production and the transportation costs are saved; and the firmness of a wall body built by the perforated bricks is enhanced.

Description

Sintering shale mine tailing porous brick

Technical field:

The utility model wall body building material technical field is more specifically to a kind of non-clay porous brick.

Background technology:

Appearance along with many new-type building structure (as frame construction, shear wall structure), except insulation, heat insulation key property, also the fragment of brick to masonry panel has proposed intensity height, light weight and has built the firm requirement of back wall by laying bricks or stones to the requirement of wall body building material.So many non-clay porous bricks occurred.

Existing non-clay porous brick forms through hole or blind hole on its right angle hexahedron, intensity, insulation, the heat-proof quality of the quantity in hole and size decision brick body, and how the quantity of aligned apertures and size while have also determined the quality of brick body.Reasonable plan is brick body light weight, good heat insulating the most, and intensity also can meet GB simultaneously.And existing non-clay porous brick hole ratio generally can't surpass 30%, and making has increased production and cost of transportation by the product quality height undoubtedly.Hexahedral its external surface of non-clay porous brick in right angle all is shaped to the plane simultaneously, and this is unfavorable for building by laying bricks or stones the whole fastness of back wall.

The utility model content:

The purpose of this utility model is to provide a kind of sintering shale mine tailing porous brick, and its hole ratio reaches 33.5%, and light weight is built the back wall fastness simultaneously by laying bricks or stones and greatly improved.

Technology solution of the present utility model is as follows:

Sintering shale mine tailing porous brick, specification is 190 * 190 * 90, form a plurality of square openings on the brick body, the central square hole gauge lattice that are in brick body center are 40 * 36, are that benchmark is symmetrically distributed with some square openings less than the central square hole around it with center, central square hole.

The square opening that described square opening less than the central square hole is a specification 33 * 12, the square opening of specification 16 * 12 or the square opening of specification 25 * 12.

Form 3-12 groove on the face of described brick body.

The cross section of described groove is square.

The beneficial effects of the utility model are:

1, be that benchmark is symmetrically distributed with some square openings less than the central square hole around it with center, central square hole.Make brick laying structure tight, the inhomogeneous brick body different piece intensity difference that causes of pore size distribution that is unlikely on the brick body is excessive.

2, the square opening less than the central square hole is the square opening of specification 33 * 12, the square opening of specification 16 * 12 or the square opening of specification 25 * 12,35 holes like this can distribute on the brick body, hole ratio reaches 33.5%, makes that the brick body weight is lighter, has saved production, cost of transportation.

3, form 3-12 groove on the face of described brick body.After being built into body of wall with mortar owing to form groove on the face, make connect between each brick body unit more firm, thereby strengthen the firmness of body of wall.

Fig. 2 is a schematic perspective view of the present utility model.

The specific embodiment:

Embodiment, see Fig. 1,2, sintering shale mine tailing porous brick, specification is 190 * 190 * 90, form a plurality of square openings on the brick body 1, central square hole 11 specifications that are in brick body center are 40 * 36, are that benchmark is symmetrically distributed with some

square openings

12,13,14 less than central square hole 11 around it with center, central square hole.

The square opening 12 that described square opening less than central square hole 11 is a specification 33 * 12, the square opening 13 of specification 16 * 12 or the square opening 14 of specification 25 * 12.

Form 3-12 groove 15 on the face of described brick body 1.

The cross section of described groove 15 is square.
