Abstract

The utility model relates to a hollow building block with a tooth surface and a cross hole, which comprises a horizontal cross hole which is arranged in an inner cavity of a cubical building block and is divided by a vertical longitudinal rib connected with the cubical building block into a whole; one side surface of the cubical building block is provided with a groove, the top surface of the cubical building block is also provided with a groove, the outer side surface of the cubical building block is provided with convex racks parallel to the top surface, and the distance between every two adjacent convex racks is b. The distance b among the convex racks parallel to one another is equal to 50-300mm, and the included angle alpha between the inclined surface of each convex rack and the top surface of the cubical building block is equal to 20-80 degrees. The convex racks on the building block can discharge rainwater attached to the outer side wall surfaces, thus being capable of preventing rainwater from leaking in a house through the building block.

Description

The building-block of the band flank of tooth and cross-drilled hole

Technical field

The utility model relates to a kind of wall body hollow block of building trade, particularly a kind of building-block with the flank of tooth and cross-drilled hole.

Background technology

Along with improving constantly of China's rapid development of economy and living standards of the people, the demand of the primary ,secondary and tertiary industries and people's residential occupancy increases severely.National Development and Reform Committee proposes time limit and substitutes conventional clay with environment-friendly energy-saving type materials for wall, the major defect of produce a large amount of land resourcess of common solid clay brick consumption to overcome, destroying ecological environment.But the endoporus of existing building-block and rib all are vertically upward, and when building a wall, the direction in its hole is vertical with the slurry surface of building block and slurry surface; In the load-bearing direction, wall that each building-block is narrow and rib contact with each other and carry, and belong to line contact load, and contact surface is little, pressure is big, discontinuity.The cross-drilled hole building-block of band groove can overcome above-mentioned deficiency, but the rainwater that outside metope adheres to can be penetrated within doors by building-block.

Summary of the invention

The purpose of this utility model provides a kind ofly can get rid of the rainwater that outside metope adheres to, can prevent rainwater by building-block be penetrated within doors the band flank of tooth and the building-block of cross-drilled hole.

The utility model is realized by following technical proposal: a kind of building-block with the flank of tooth and cross-drilled hole, the inner chamber that is included in the cube building block is provided with by the horizontal cross-drilled hole of separating with the vertical vertical rib that the cube building block fuses, a side in the cube building block is provided with lateral grooves, end face in the cube building block is provided with the end face groove, be provided with at the lateral surface of cube building block and be parallel to end face, spacing is the convex tooth strips of b.The spacing b=50-300mm of described convex tooth strips parallel to each other, angle α=20 between the end face of the inclined-plane of convex tooth strips and described cube building block °-80 °.The spacing b of described convex tooth strips parallel to each other is respectively 80mm, 120mm, 160mm, 200mm or 250mm, angle α=20 between the end face of the inclined-plane of convex tooth strips and described cube building block °-80 °.The spacing b=50-300mm of described convex tooth strips parallel to each other, the angle α between the end face of the inclined-plane of convex tooth strips and described cube building block is respectively 30 °, 40 °, 50 °, 60 ° or 70 °.

The beneficial effects of the utility model are:

1, the lateral surface in the cube building block is provided with the convex tooth strips that is parallel to end face, can get rid of the rainwater that outside metope adheres to, and can prevent that rainwater is penetrated within doors by building-block.

2, the groove that is provided with of side improves the adhesive power and the wall plaster quality of masonry dust greatly; The building block end face is provided with groove, and masonry masonry mortar construction back forms the sealing rib, improves and strengthen body of wall percolation-proof effect.

When 3, building a wall, horizontal cross-drilled hole of the present utility model is parallel with the slurry surface and the slurry surface of building block, face contact power transmission is changed in the line contact power transmission of traditional building-block, thereby improved the stressed uniformity of building block and the intensity of masonry greatly.

4, be provided with the horizontal cross hole, porosity 〉=40%, materials are few, and are in light weight, can reduce the load of basis and body of wall, and help insulation, heat insulation, sound insulation and energy-conservation.

5, in masonry can with vertical core building block usefulness mutually, can realize bearing wall collar tie beam non-mould construction simultaneously.

6, adopt mixed materials such as cement, flyash, slag, gypsum, sandstone, economize the land resource, help environmental protection.
