Abstract

The utility model discloses an integral-type concrete hollow brick which comprises a hollow brick body which is of a barrel-shaped structure with an upper opening and a lower opening which are formed through the surrounding of a first pair of lateral walls and a second pair of lateral walls. The first pair of lateral walls respectively protrude out of the outer surfaces of the second pair of lateral walls from the two sides. The integral-type concrete hollow brick also comprises a top wall which is positioned at the upper side of the second pair of lateral walls and used for closing the upper opening of the hollow brick body. The upper surface of the top wall is lower than the upper surface of the first pair of lateral walls, and the top wall is integrated with the first and the second pairs of lateral walls into a whole. The hollow brick not only is light and has good heat insulation and firm connection but also does not need the purposeful alternation and seam performance which are needed by a solid brick, greatly improves the wall building speed and facilitates the production and use.

Description

The integral concrete hollow brick

Technical field

The utility model relates to a kind of building unit that is used to build a wall, and relates in particular to a kind of concrete hollow block.

Background technology

The existing building unit that is used to build a wall generally can be divided into two kinds, and a kind of is solid brick, and a kind of is hollow brick.Solid brick is that member is used in traditional building a wall, and cost is low, but along with the scarcity of cultivated land resource, solid brick is just slowly withdrawn from the market.Hollow brick is in light weight, and heat preservation and insulation is good, also can save a large amount of clay consumption, the cultivated land resource of saves valuable, and therefore, it has been widely used on the various construction walls.But the hollow block that uses mainly contains following shortcoming at present:

1) only bonding between the hollow brick by mortar, cause the shearing resistance tensile strength of body of wall low, can not use as load bearing wall.

2) for weight reduction, hollow block mostly is provided with lower through-hole, and the real contact area between the upper and lower hollow brick only is about 47% of the area of plane, drains to easily in the through hole when plastering slurry, causes waste, and it is slow to build a wall, and efficiency of construction is low.

Summary of the invention

Technical problem to be solved in the utility model is: a kind of integral concrete hollow brick is provided, and it is not only in light weight, and heat insulation and preservation effect is good, and the speed of building a wall is fast, and institute's body of building a wall is more firm.

For solving the problems of the technologies described above, the technical solution of the utility model is: the integral concrete hollow brick, comprise the hollow brick body, described hollow brick body surrounds the tubular structure of upper and lower opening by first oppose side wall and second oppose side wall, and described first oppose side wall protrudes from the external surface of described second oppose side wall respectively from both sides; Also comprise a upside that is positioned at described second oppose side wall, be used to seal the roof of described hollow brick upper part of body opening, the upper surface of described roof is lower than the upper surface of described first oppose side wall, and described roof and described first oppose side wall and second oppose side wall are made as one.

After having adopted technique scheme, the beneficial effects of the utility model are: because the hollow brick body is surrounded the tubular structure of upper and lower opening by first oppose side wall and second oppose side wall, described first oppose side wall protrudes from the external surface of described second oppose side wall respectively from both sides, so between two blocks of adjacent hollow bricks of level, so between two blocks of adjacent hollow bricks of level, can form a cavity, and in this cavity, can pour into cement mortar.Owing to also comprise a upside that is positioned at described second oppose side wall, be used to seal the roof of described hollow brick upper part of body opening, the upper surface of described roof is lower than the upper surface of described first oppose side wall, roof not only can be strengthened the intensity of hollow brick, and can play the effect of support cement mortar.When building a wall, on the roof of lower floor's hollow brick, spread cement mortar earlier, and make cement mortar protrude from the uper side surface of first oppose side wall, and then put the upper strata hollow brick, at this moment, the cement mortar of the uper side surface that protrudes from first oppose side wall on lower floor's hollow brick can stretch into the lower openings of upper strata hollow brick, and each hollow brick is just surrounded by cement mortar on every side like this, after it solidified, all hollow bricks just were fixed together.This hollow brick is not only in light weight, and thermal and insulating performance is good, is connected firmly, and need not to have improved the speed of building a wall greatly as the painstakingly staggered adjacency seam of solid brick.Because described roof and described first oppose side wall and second oppose side wall are made as one, can make things convenient for the manufacturing and the use of hollow brick greatly.

Description of drawings

Below in conjunction with drawings and Examples the utility model is further specified.

Fig. 1 is the longitudinal sectional view of the utility model embodiment;

Fig. 2 is the sectional view at A-A place among Fig. 1;

Fig. 3 is to use the longitudinal sectional view of body that the utility model is built a wall.

The specific embodiment

Shown in Fig. 1 and Fig. 2 are common, a kind of integral concrete hollow brick, it comprises the hollow brick body, described hollow brick body surrounds the tubular structure of upper and lower opening by first oppose side wall 1 and second oppose side wall 2, and described first oppose side wall 1 protrudes from the external surface of described second oppose side wall 2 respectively from both sides.When two hollow brick levels were adjacent, the projection of first oppose side wall 1 and adjacent second oppose side wall 2 will form a cavity (as shown in Figure 3) that can pour into cement mortar.

Roof 4 is positioned at the upside of described second oppose side wall 2, is used to seal described hollow brick upper part of body opening, and roof not only can be strengthened the intensity of hollow brick, and can play the effect of support cement mortar.The upper surface of described roof 4 is lower than the upper surface of described first oppose side wall 1, and the purpose of She Zhiing is to make the space that the filling concrete mortar is also arranged between upper strata hollow brick and the lower floor's hollow brick like this.

In order to improve support strength, supporting walls 3 is set between the inner surface of first oppose side wall 1 to roof 4.Same effect, supporting walls 3 also can be arranged between described second oppose side wall, 2 inner surfaces.

Clearly, first oppose side wall 1, second oppose side wall 2, roof 4 and the supporting walls 3 of hollow brick body all are made as one, and adopt with a kind of concrete material, can make things convenient for the manufacturing and the use of hollow brick greatly.

As shown in Figure 3, when building a wall, at first, put together side by side in the end of first oppose side wall 1 of concrete hollow block, in the protuberance of first oppose side wall 1 of the adjacent concrete hollow block of two levels and space that second oppose side wall 2 surrounds, inject mortar.Then, on the roof 4 of lower floor's hollow brick, spread cement mortar, and make cement mortar protrude from the uper side surface of first oppose side wall 1, put the upper strata hollow brick again, at this moment, the cement mortar of the uper side surface that protrudes from first oppose side wall 1 on lower floor's hollow brick can stretch into the lower openings of upper strata hollow brick, and each hollow brick is just surrounded by cement mortar on every side like this, after it solidified, all hollow bricks just were fixed together.This hollow brick is not only in light weight, and thermal and insulating performance is good, is connected firmly, and need not to have improved the speed of building a wall greatly as the painstakingly staggered adjacency seam of solid brick.
