Description

technical field

[0001] The invention relates to the field of building detection equipment, in particular to a pull-out bearing capacity detection device of a hoisting point of a concrete prefabricated member. Background technique

[0002] The construction of prefabricated buildings is a large number of on-site assembly operations, which is greatly reduced compared to the original cast-in-place operations. However, because it is a prefabricated part, the prefabricated structural part should be hoisted from the ground to the construction area by lifting equipment during use. In the actual construction process, the prefabricated lifting points will be embedded in the prefabricated parts, and the general structure is U-shaped screw steel lifting points. Before hoisting, it is necessary to sample the prefabricated parts to test the strength of the hoisting point to prevent safety accidents due to loose hoisting points during the actual hoisting process. The current device is ge...
