Abstract
The utility model relates to an anti-earthquake type concrete small sized hollow block, which is building materials, particularly the improvement of common concrete small sized hollow blocks. A plane contact structure positioned between original upper and lower layer blocks are changed to a structure that a circle of bosses of the lower layer blocks are protruded along inner walls, and are sheathed in the hollow parts of the upper layer blocks; when the shear force of the earthquake is exerted on block masonries, the move of the upper layer blocks is blocked by the bosses of the lower layer blocks. When the utility model is used for building, the loss of mortar can be resisted, and the compressive strength of mortar layers can be enhanced.
Description
The utility model is a kind of constructional materials, particularly about a kind of improvement of Normal concrete small hollow block.
Original Normal concrete small hollow block, contact surface is little between the levels, and only the thickness of its wall rib is about 2～3.5 centimetres, and the masonry globality is poor, and shear strength is low, poor seismic behavior, the use in area is restricted more than fortification intensity 6 degree.In addition, a kind of wave mode and sawtooth pattern concrete hollow block are arranged, horizontal mortar joint is not a straight line, can not do dry wall, and this building block boss does not influence outward appearance in hollow.Wave mode and sawtooth pattern concrete hollow block have only improved masonry shear strength.And this building block body not only shear strength improve a lot, and other advantage is arranged.
The purpose of this utility model is to improve the shearing resistance and the compressive strength of concrete small size hollow building block, strengthens the anti-seismic performance of concrete small size hollow building block; Improve masonry quality, and save masonry mortar.
Design scheme of the present utility model is: it is to the reform of former concrete small size hollow building block, the plane contact structure between the building block of former upper and lower layer, become the platform of lower floor's building block along inwall epirelief one circle, be inserted in upper strata building block hollow, make block masonry when being subjected to the horizontal earthquake shearing, lower floor's building block boss stops that the upper strata building block is moved, when building by laying bricks or stones, stop the loss of mortar, and improve the compressive strength and the bubble full scale of screed.
This small-sized hollow elements of block for against vibrations of being made by concrete is characterized in that: on the end face of building block boss is arranged, and the rectangle frustum that is shaped as the band arc chord angle of boss, the centre is hollow, the top of the facade of boss and building block can have certain angle.Boss also can be ellipse, 2 centimeters to 4 centimeters of boss height, and boss also can be made solid.
The utility model advantage compared with prior art:
1, because of stopping of boss makes screed easily be paved with difficult the loss, improves mortar bubble full scale, save mortar.
2, because of the constraint of boss, make screed when pressurized, become local compression, improved the compressive strength of screed, the masonry strength increase rate when especially mortar strength is zero is bigger, and build by laying bricks or stones highly and increase the every day when making the building block construction, accelerated speed of application.
3, because of lower floor's building block boss be inserted in the upper strata building block hollow in, the contact surface of building block of upper and lower layer and mortar is increased than standard block, improved the globality of masonry
4, the mortar between lower floor's building block boss and the upper strata building block, at first crushed when earthquake, elastic-plastic deformation repeatedly takes place, a large amount of absorptions seismic energy, in earthquake, played the effect of " dissipative cell ", improved the shock resistance of masonry.
5, when earthquake, boss can stop between the building block and vertically is being moved, and makes masonry continue performance load-bearing effect, prevents house collapse.
6, when earthquake, boss can stop between the building block and laterally is being moved, and prevents that masonry from collapsing.
Accompanying drawing 1 is the building-block vertical view of hollow boss.
Accompanying drawing 2 is the structural representation of hollow boss.
Accompanying drawing 3 is the oval hollow boss diagrammatic sketch of bowing.
Accompanying drawing 4 is solid boss structure schematic diagram.
Accompanying drawing 5 is the utility model user mode schematic diagram.
In the accompanying drawing, 1. being boss, 2. is the upper surface, 3. is hollow, 4. is the building block main body.
Most preferred embodiment is the concrete small size hollow building block of the square hollow boss of belt length, as shown in Figure 1, boss 1 highly be 2 centimeters better, during use as shown in Figure 5, the boss 1 of lower floor's building block be inserted in the upper strata building block hollow 3 in, the levels building block has increased than standard block with the contact surface of mortar like this, improved the globality of masonry, and boss 1 has stoped relatively moving between the levels building block, has improved masonry shear strength, makes the anti-seismic performance in block masonry house that bigger enhancing be arranged.
Claims (6)
1, a kind of small-sized hollow-brick block of being made by concrete of Antiseismic concrete is characterized in that: on the end face of building block boss is arranged.
2, Antiseismic concrete small-sized hollow building block according to claim 1, its feature also is: be hollow in the middle of the rectangle frustum that is shaped as the band arc chord angle of boss.
3, Antiseismic concrete small-sized hollow building block according to claim 1, its feature also is: there is certain angle the facade of boss and the upper surface of building block.
