Description

Technical Field

[0001] The utility model relates to the technical field of building strength detection, in particular to a brickwork shear strength detection device. Background Art

[0002] Brick wall masonry directly bears the lateral horizontal load, and masonry in earthquake-resistant areas is subject to horizontal earthquake loads, both of which require the masonry to have corresponding shear strength. In the prior art, during the shear strength test of the wall, when the wall breaks, the constructors judge whether the shear strength test of the wall is completed by the sound made by the wall break. In a noisy construction environment or when the sound made by the wall break is low, it is not conducive for the constructors to judge whether the shear strength test of the wall is completed, resulting in the constructors being able to judge that the shear strength test of the wall is completed only after observing obvious fractures in the wall, which leads to low efficiency in the shear strength test of the wall.
