Abstract

The invention relates to a movable hoisting apparatus and a construction installation method used by the same. The apparatus comprises a hanger, the hanger is connected with a screw via a nut, a supporting retaining component is arranged at the side of the hanger, and a concrete prefabricated component is arranged at the bottom of the hanger. The method comprises: S1, prefabrication of the concrete prefabricated component and the supporting retaining component, arranging a preformed-hole casing pipe in the concrete prefabricated component; S2, assembling the hanger, preparing the screw, the nut and a steel base plate; S3, making the screw penetrate the preformed-hole casing pipe, fixedly connecting the top and the bottom of the concrete prefabricated component to the hanger respectively via the screw and the steel base plate; S4, packing wedge-shaped steel plate pair between the hanger and the supporting retaining component; S5, hoisting the concrete prefabricated component and placing at a concrete prefabricated component installing pedestal; s6, successively dismounting the top connection and the bottom connection of the screw, the nut, the steel base plate, the screw, the hanger, positioning components and the wedge-shaped steel plate pair; and S7, pouring the supporting retaining component with a cast-in-situ surface layer. The movable hoisting apparatus is convenient to make and install and is reusable; and the prefabrication field and the prefabrication manner need no reconstruction, and thus the movable hoisting apparatus and the construction installation method used by the same are 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...
