Problems solved by technology

However, in the actual hoisting process, the hoisting point is cable-stayed, so there is a big gap between the actual hoisting and the pull-out test process, and the results obtained cannot intuitively reflect that the hoisting state is the maximum force that the hoisting point can bear

Embodiment

[0023] Example: In the construction of prefabricated buildings, structural parts are generally prefabricated in the factory, and then the prefabricated structural parts are pulled to the construction site for assembly. In the building construction specification, the bearing capacity of the lifting point needs to be tested by batch sampling. The hoisting point of the reinforced concrete prefabricated structure is generally to bend the rebar into an inverted U shape, and there are return hooks on both sides of the bottom end to increase the grip with the concrete. The test is used to determine that the position of the lifting point can effectively carry the weight of the entire prefabricated structure and prevent the lifting point from being pulled out during the actual lifting process.

[0024] The pullout bearing capacity detection device of the lifting point of the concrete prefabricated member includes a first jacking cylinder 1, a second jacking cylinder 2, a sling 3, a firs...

Abstract

The invention discloses an anti-drawing bearing capacity detection device of concrete prefabricated part lifting points and mainly relates to the field of building detection equipment. The device comprises a sling and an ejection device, wherein a force measuring device is arranged on the sling, the two ends of the sling are provided with the lifting points for hooking, the ejection device can perform upward ejection, the top of the ejection device is connected with the sling, and the ejection device drives the sling to move upwards. The device has the advantages that the state of the diagonallifting points in actual lifting is simulated, and the two lifting points are tested simultaneously.

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...
