Problems solved by technology

[0002]At present, in the field of masonry structures, the existing technologies are mostly layer-by-layer block building, that is, the common blocks are rectangular parallelepiped, and each After the bricks of the first layer are built, they are not aligned with the brick joints of the upper layer of blocks in the vertical direction, so as to strengthen the integrity of the masonry. However, in the horizontal direction, because the layers of the blocks can Form a plane, the friction between the block and the mortar is very small, and the shear bearing capacity of the masonry is very low; so the masonry has poor ability to resist external forces in the horizontal direction, and it is easy to be damaged under stress conditions
[0003] In the prior art, there is also a masonry made of hexagonal concrete hollow blocks, which can increase the bearing capacity in the vertical direction, but still It is difficult to increase the shear capacity in the horizontal direction

Embodiment 1

[0027] In the method described in the present invention, the masonry includes blocks built layer by layer. The two ends of the masonry are cast-in-place reinforced concrete columns 7, and the connection between the masonry and the masonry between floors is a cast-in-place reinforced concrete beam 8. After construction, the mortar joints between the blocks, the mortar joints between the blocks and the 8 cast-in-place reinforced concrete beams, and the horse teeth between the blocks and the 7 cast-in-place reinforced concrete columns respectively constitute regular and incoherent joint surfaces. Mortar 4 is laid between the blocks.

[0028] The masonry consists of blocks, cast-in-place reinforced concrete beams 8 and cast-in-place reinforced concrete columns 7 .

[0029] The regular and non-coherent joint surface mentioned in the present invention refers to the non-linear shape of the cross section of the joint surface. concave surface.

[0030] Construction results such as ...

Embodiment 2

[0033] The structure and steps of block masonry are the same as in Example 1.

[0034] Such as Figure 8-13 , the first block 2 is formed by at least two "convex" shaped polygonal prisms with gaps at the bottom, staggered and spliced ​​on the side plane; The cavities formed by the first four blocks of the first block are consistent, and the shape of the third block 6 is matched with the first block 2 . This structure can make the surface between the layers of the block a stepped surface with undulations, thereby avoiding the linear structure of the interval between the layers, and greatly improving the horizontal shear bearing capacity of the masonry.

[0035] The "convex"-shaped polygonal prisms in the embodiment are staggered and spliced ​​on the front surface, mainly referring to the splicing of two "convex"-shaped blocks with gaps on the lower surface, and the two shoulders of the "convex" font itself do not require Equal lengths, but the blocks themselves are centrally ...

Embodiment 3

[0038] Such as Figure 17 , the structure of each building block is the structure in embodiment 1 or the structure in embodiment 2 at the same time. The way of masonry results in the absence of a third block 6. This method has a correspondingly simple structure and is more convenient for construction.

Abstract

The invention relates to a construction method implemented during execution of works, in particular to a method for constructing masonry from concrete hollow blocks. The masonry constructed by the method comprises blocks which are constructed layer by layer, cast-in-place reinforced concrete columns are arranged at two ends of each block, cast-in-place reinforced concrete beams are arranged at joints of the blocks among floors, and regular and discontinuous joint surfaces are respectively formed by mortar joints among the various blocks, mortar joints among the blocks and the cast-in-place reinforced concrete beams and toothed joints among the blocks and the cast-in-place reinforced concrete columns after the masonry is constructed. Mortar is constructed among the blocks. The method has the advantages that shortcomings of low horizontal shear capacity and poor integrity of existing masonry are overcome by the masonry constructed by the method; the horizontal shear capacity of the masonry is greatly improved, the integrity and the mechanical property of the masonry are improved, accordingly, the masonry can be applied to middle and high-rise buildings, and a part of a cast-in-place shear wall can be replaced.
