Hollow block masonry structure with high shear resistance

Abstract

The invention discloses a hollow block masonry structure with high shear resistance. The hollow block masonry structure is formed by laying hollow concrete blocks in a vertically adjacent layer staggered lap joint manner, wherein each hollow concrete block comprises a block body, a horizontal support bulge is integrally arranged on the inner cavity wall of the block body and arranged in the horizontal direction of the masonry structure, a plurality of prefabricated shear-resistant blocks are inserted into cavities of every two adjacent upper and lower layers of hollow concrete blocks, and thelower ends of the prefabricated shear-resistant blocks and the upper ends of horizontal support bulges in the cavities of the corresponding hollow concrete blocks on the lower layer form support contact; fit clearance of the prefabricated shear-resistant blocks and the corresponding hollow concrete blocks on the upper and lower layers is filled with mortar, and mortar joints are formed; two adjacent upper and lower layers of prefabricated shear-resistant blocks are arranged in a staggered manner. The hollow block masonry structure ensures that the hollow blocks and shear-resistant blocks can better cooperate to work in the wall building process, and the shear resistance capability of a wall is notably improved.

Description

technical field [0001] The invention belongs to the field of building structures, in particular to a hollow block masonry structure with high shear resistance. Background technique [0002] As a common structural system, masonry structure is widely used in most areas of our country. However, in many earthquake disasters, it is found that masonry structure houses have been damaged to varying degrees, especially in recent years. Several large earthquakes have caused serious damage to rural masonry houses, and even collapsed, resulting in significant economic and human losses. The reason is that the lack of shear strength is the main factor leading to the collapse of the house. This is because the shear resistance of the masonry structure is mainly provided by the friction and cohesion of the mortar between the blocks. Once the shear force on the masonry If it is too large, there will be slippage between the block layers and the layers, which will cause the wall to lose its be...

This is because the shear resistance of the masonry structure is mainly provided by the friction and cohesion of the mortar between the blocks. Once the shear force on the masonry If it is too large, there will be slippage between the block layers, which will cause the wall to lose its bearing capacity
