Abstract

The invention relates to a movable lifting device and a construction and installation method thereof. The device includes a lifting lug, which is connected to a screw rod through a nut. The side of the lifting lug is provided with a support block, and the bottom of the lifting lug is provided with a concrete prefabricated part; The method includes: S1, prefabrication of concrete prefabricated parts and retaining parts, embedding reserved hole sleeves in the concrete prefabricated parts; S2, assembling lifting lugs, preparing screw rods, nuts, and steel backing plates; S3, screw rods passing through the reserved holes The casing, the top and bottom of the concrete prefabricated part are fixedly connected by nuts, steel backing plates and lifting lugs; S4, wedge-shaped steel plates are filled between the lifting lugs and the support and retaining parts; S5, the concrete prefabricated part is hoisted and placed on the concrete prefabricated part installation support On the seat; S6, remove the top and bottom nuts of the screw rod, steel backing plate, screw rod, lifting lug, positioning parts and wedge-shaped steel plates in sequence; S7, pour the supporting parts and the cast-in-place surface layer together. The invention is easy to manufacture and install, realizes repeated use, does not need to modify the prefabricated site and the prefabricated method, and is easy to popularize and apply.

Description

technical field [0001] The invention relates to a novel movable lifting device. Background technique [0002] Large concrete prefabricated parts are common structures in the engineering field, and are widely used in engineering fields such as ports and bridges. At present, pre-embedded steel components, rings, etc. are commonly used in engineering as the lifting device for large concrete prefabricated parts. After the lifting is completed, it will fail. Since it is a non-removable and replaceable device, each prefabricated Certain hoisting materials, the hoisting cost is relatively high. [0003] In the current environment of increasingly fierce market competition and rising costs, reducing engineering costs and improving corporate competitiveness is the goal that engineering companies are constantly pursuing, and it is also in line with the development trend of energy conservation and emission reduction. Contents of the invention [0004] The technical problem to be sol...
