Referring to fig. 1 to 7, a hollow block masonry structure with built-in prefabricated shear blocks is formed by masonry of concrete hollow blocks 1 in a mode of overlapping upper and lower adjacent stacking fault seams, and has the innovation points that:
The prefabricated shear block 2 is arranged in the alignment cavity of the two concrete hollow blocks which are connected up and down, and consists of a shear block body part 2-1 and a supporting cross arm part 2-2. The supporting cross arm part is in a rod shape or a strip shape, and the diameter or the thickness of the supporting cross arm is smaller than the thickness of the horizontal mortar joint 3 of the masonry structure. The middle section of the supporting cross arm part is buried in the shear block body part, and two end parts of the supporting cross arm extend out of two sides of the shear block body respectively and are supported on rib walls at two sides of a cavity of the lower concrete hollow block, so that the upper half part and the lower half part of the shear block body part extend into the cavity of the corresponding upper concrete hollow block and the cavity of the corresponding lower concrete hollow block respectively. Mortar is filled between the periphery of the shear block body part and the inner walls of the cavities of the corresponding upper and lower concrete hollow blocks to form a vertical mortar joint 4, so that the upper and lower corresponding two concrete hollow blocks form shear connection through the prefabricated shear blocks.
The prefabricated shear blocks are further preferably uniformly arranged in the whole hollow block masonry structure in a staggered mode according to the upper adjacent layers and the lower adjacent layers, so that connection among the layer-by-layer concrete hollow blocks is ensured through the prefabricated shear blocks, and the shear resistance and the integrity of the hollow block masonry are greatly improved.
The cross arms of the prefabricated shear block can be single or multiple, and under the condition of multiple cross arms, the cross arms are uniformly distributed in the same plane, so that the cross arms are simultaneously supported on the rib walls on two sides of the cavity of the concrete hollow block, and the stability and the firmness of the support of the prefabricated shear block are ensured.
The shape of the cross arm portion of the prefabricated shear block is further preferably two of the following:
1. The support cross arm part is in a straight shape, and thus, two straight extending ends of the support cross arm are supported on two side rib walls of the cavity of the concrete hollow block.
2. The support cross arm part is L-shaped and horizontally placed, so that one end extending out of one side of the prefabricated shear block is provided with a vertical edge to form a hook-shaped structure, and the vertical edge part of the support cross arm is hooked on the cavity wall of the concrete hollow block adjacent to the lower concrete hollow block in the same layer. The support cross arm adopts an L-shaped structure, and compared with the support cross arm in the shape of a straight line, the overall performance of the masonry structure can be further enhanced to a certain extent.
When the support cross arm portion is of a rod-like structure, the support cross arm portion is preferably of a steel bar or wire having a diameter of less than 6 mm.
When the support cross arm part is in a flat strip shape, the support cross arm part is preferably made of a thin steel sheet with the thickness of less than 6 mm.
The outer shape of the shear block body part can be rectangular (see fig. 2-5), dog-bone-shaped (see fig. 6) or pyramid-shaped (see fig. 7) with four rounded corners, and the shear block body part is dog-bone-shaped or pyramid-shaped, so that the material can be saved, the dead weight of the structure can be lightened, and in addition, heat insulation materials and the like can be filled between the block cavity and the gap of the prefabricated shear block.
