Description

A coal gangue sintered brick

【Technical field】

The utility model relates to a wall material, in particular to a coal gangue sintered brick with seven rows of holes.

【Background technique】

In order to solve the sustainable utilization of natural resources, the country prohibits the use of clay bricks. In recent years, many enterprises use coal gangue waste to produce wall materials. At the same time, the country advocates green, energy-saving and environmentally friendly buildings. The heat transfer coefficient of the wall material is lower than 1.5w/m ² k. Only the seven-row rectangular hole sintered brick applied by Longyan Kejing Hollow Brick Co., Ltd. can meet the index requirement of less than 1.5w/m ² k. The thermal coefficient is 1.48w/m2k, which is only slightly lower than the index requirement, but its strength is as high as 20MPa, while the existing national index only requires 10MPa, and at the same time, it makes its own weight too large. The number of holes in this patent is too large, resulting in too many brick ribs. This part acts as a thermal bridge and reduces the self-insulation performance of the wall material.

【Content of invention】

The technical problem to be solved by the utility model is to provide a coal gangue sintered brick, which can not only achieve a good self-insulation effect, but also reduce its own weight.

The utility model is achieved in that:

A coal gangue sintered brick, the coal gangue sintered brick includes a sintered brick body and seven rows of rectangular holes arranged on the sintered brick body, the seven rows of rectangular holes include four rows of first rectangular hole groups and three rows of The second rectangular hole group, and the first rectangular hole group and the second rectangular hole group are arranged at intervals, the first rectangular hole group includes three first rectangular holes, and the second rectangular hole group includes two second rectangular holes hole.

Further, the specification of the fired brick body is 240mm×190mm×90mm, the distance between the outermost rectangular hole and the upper and lower edges of the fired brick body is 23mm, and the distance from the left and right edges of the fired brick body is 15mm; The specification of the first rectangular hole is 60mm * 12mm * 90mm, the distance between each adjacent first rectangular hole is 15mm, the specification of the second rectangular hole is 95mm * 12mm * 90mm, each adjacent The distance between the second rectangular holes is 20 mm; the distance between each of the first rectangular hole groups and the adjacent second rectangular holes is 10 mm.

The utility model has the advantages of:

The utility model can greatly reduce the heat transfer coefficient to 1.45w/m ² k, and at the same time, the wall material strength can reach 15MPa; It has a good self-insulation effect, and at the same time reduces its own weight.

【Description of drawings】

The utility model will be further described below in conjunction with the embodiments with reference to the accompanying drawings.

Fig. 1 is the structural representation of the utility model.

【Detailed ways】

Referring to Fig. 1, the embodiment of the present utility model is described in detail.

As shown in Figure 1, a coal gangue sintered brick related to the utility model, the coal gangue sintered brick includes a sintered brick body 1 and seven rows of rectangular holes arranged on the sintered brick body 1, the seven rows of The rectangular holes include four rows of the first rectangular hole group 2 and three rows of the second rectangular hole group 3, and the first rectangular hole group 2 and the second rectangular hole group 3 are arranged at intervals, and the first rectangular hole group 2 includes three a first rectangular hole 21, and the second rectangular hole group includes two second rectangular holes 31.

The specification of the sintered brick body is a1×b1×c1=240mm×190mm×90mm, the distance between the outermost rectangular hole and the upper and lower edges of the sintered brick body is H1=23mm, and the distance between the left and right edges of the sintered brick body The spacing is H2=15mm; the specification of the first rectangular hole is a2×b2×c2=60mm×12mm×90mm, the spacing between each adjacent first rectangular hole is H3=15mm, the second The specification of rectangular hole is a3 * b3 * c3=95mm * 12mm * 90mm, and the spacing between each adjacent described second rectangular hole is H4=20mm; The distance between the rectangular holes is H5=10mm.

The utility model can greatly reduce the heat transfer coefficient to 1.45w/m ² k, and at the same time, the wall material strength can reach 15MPa; It has a good self-insulation effect, and at the same time reduces its own weight.

Although the specific embodiments of the present utility model have been described above, those skilled in the art should understand that the specific embodiments we describe are only illustrative, rather than used to limit the scope of the present utility model. Equivalent modifications and changes made by those skilled in the art in accordance with the spirit of the present utility model shall fall within the protection scope of the claims of the present utility model.
