Anti-shear connecting structure used for hollow block masonry, masonry wall and construction method

Abstract

The invention discloses an anti-shear connecting structure used for hollow block masonry, a masonry wall and a construction method. The anti-shear connecting structure is arranged at the layered position of upper skin and lower skin of a masonry structure and is composed of two L-shaped supporting angle plates and a concrete anti-shear block, the two supporting angle plates are symmetrically arranged in a cavity of the hollow block in a paired manner, upper transverse sides of the two supporting angle plates are supported on rib walls of two sides of the cavity and are bonded with two side rib walls through mortar, and the concrete anti-shear block is arranged between the two supporting angle plates and is supported on the lower transverse sides of the two supporting angle plates in a lap-joint manner; the upper half portion and the lower half portion of the concrete anti-shear block are embedded in an upper skin building block cavity and a lower skin building block cavity, and are bonded with the two supporting angle plates and the inner cavity wall of the hollow block through mortar arranged outside the periphery in a filling manner. According to the anti-shear connecting structure, cracking on the wall mortar joint can be reduced, the anti-shear strength of the masonry wall structure is improved, the wall has the higher integrality, the masonry wall with the anti-shear connecting structure has the higher anti-shear strength and the higher integrality, and the construction method of the masonry wall is simple and reliable.

Description

technical field [0001] The invention belongs to the field of building wall structures, and in particular relates to a shear connection structure suitable for air block masonry, a masonry wall adopting the shear connection structure and a construction method of the masonry wall. Background technique [0002] Concrete small hollow block masonry structure is one of the most widely used structural forms in my country at present. It has the advantages of light weight, good thermal performance, good wall flatness, and high construction efficiency. However, the damage of masonry structures mostly occurs in the shear failure of horizontal mortar joints. Under the action of horizontal earthquakes, masonry structures often result in insufficient bonding force between blocks and mortar, low interlayer shear strength, and poor integrity. Serious damage occurred. Therefore, how to effectively improve the shear capacity of masonry structures and improve the seismic performance of masonry...

Problems solved by technology

[0004] However, due to my country's remote rural areas and vast mountainous areas, limited to the relative shortage of important building materials such as cement and steel bars, poor transportation conditions, and high costs, the above-mentioned strengthening measures have not been widely adopted, and a large number of farm buildings are still due to insufficient shear resistance. There are major security risks
