Abstract
The utility model provides a novel hollow concrete building block. The vertical holes along the height direction of the building block is changed into transverse holes, namely, the end surface of the building block is provided with two sliver-shaped through holes along length direction. A horizontal mortar joint contacting surface of the concrete hollow building block with the structure is the same with a solid building block which achieves 100 percents. The shearing resistanace and the tensile strength of a wall built by the hollow concrete building block are raised. Therefore, cracks caused by the heat of the wall is effectively overcome, and the leakage problem caused by the cracks is also overcome.
Description
Technical field
The utility model relates to a kind of constructional materials, particularly a kind of novel concrete hollow building block.
Background technology
Available coagulation soil building-block as shown in Figures 1 and 2, it is long to be L, height is H, wide is D.Pressure-bearing surface in building block is provided with two through holes 1 along short transverse.When building a wall, the through hole 1 in the building block is erect.There is wall crazing in this structure of hollow building block, causes building to produce " heat, split, ooze ".Cause the main cause of concrete holllow building block wall cracking to have following:
The one, the shearing resistance of building-block masonry draws intensity to have only 50% of solid block, and this is that the real contact area of building block and building block only is about 47% of the area of plane, causes at the bottom of the shearing resistance tensile strength because the opening of existing building-block is erect up.
The 2nd, the building block wall is thin, and horizontal mortar joint mortar bonded area is few.Perps is big, and it is poor that mortar is built plumpness by laying bricks or stones, so stress is more concentrated, easily causes along mortar joint to produce the crack.
The 3rd, the building-block that has now is single bigeminy pore structure, and thermal and insulating performance is poor, and the 190mm blockwork only is equivalent to the clay tile wall of 140mm equivalent, can not satisfy modern architecture and reach energy-conservation 50% requirement.
Summary of the invention
The purpose of this utility model is to provide a kind of shearing resistance to draw intensity big for the above-mentioned deficiency that overcomes prior art, the building block wall thickness, and horizontal mortar joint mortar bonded area is big, the novel concrete hollow building block that thermal and insulating performance is good.
Technical solution of the present utility model is such: will change cross-drilled hole into along the vertical core of building block short transverse, and alongst establish two strip through holes at the end face of building block.Adopt that the horizontal mortar joint contact area of concrete hollow block of this structure is the same with solid block to have reached 100%, improved the shearing resistance tensile strength of hollow concrete block wall greatly, thus overcome effectively body of wall because of heat split, because of splitting the problem of oozing.
In order further to improve the shearing resistance tensile strength and the heat insulation and preservation effect of the concrete hollow block after improving, also can adopt following improvement project: the one, with end sealing along building block length direction strip through hole, establish two apertures on the end face of sealing, aperture communicates with the strip hole respectively.When the end face of two block concrete building-blocks contacted, one can increase the mortar contact surface, and two can cut off the rectangular through hole in the building block, play the effect of sound insulation, insulation, antiseepage; The 2nd, on two pressure-bearing surfaces of building block, establish two row's apertures, the corresponding strip hole of row's aperture, aperture and strip hole connect.When the pressure-bearing surface of two block concrete building-blocks contacts, below mortar on building block pressure-bearing surface will enter in the aperture on the top building block pressure-bearing surface, play reinforcement effect; The 3rd, on the end face of building block sealing, establish two strip projections, establish two grooves that match with the strip projection at the other end of building block, the aperture on the projection communicates with the strip hole.When two block concrete building-block end faces contacted, the projection on block end faces was embedded in the groove of another building block, further strengthens the stability of two building blocks.
