Installing device of residential PC prefabricated part and installing method of PC prefabricated part

Abstract

The invention relates to an installing auxiliary tool of a residential PC prefabricated part. The installing auxiliary tool comprises a vertical rod arranged on the pre-assembled PC prefabricated part. The vertical rod and the pre-assembled PC prefabricated part are in detachable connection. At least three sets of positioning heads are arranged at the lower end of the vertical rod. The positioning heads are each of a hemispherical structure, and the lower end surfaces of the positioning heads are located in the same plane. Positioning bowls corresponding to the positioning heads are arranged besides a base PC prefabricated part located on the ground. The diameter of the bowl openings of the positioning bowls is matched with the maximum size of the positioning heads. The diameter of the bowl bottoms of the positioning bowls is matched with the diameter of the upper ends of the positioning heads. A baffle with the horizontal plate surface is arranged at the bowl bottoms of the positioning bowls. A driving mechanism drives the baffle to reciprocate horizontally and be away from or stretch into the bowl bottoms of the positioning bowls. According to the installing auxiliary tool, simplified positioning can be conducted on a plurality of pre-buried holes and pre-buried steel bars, the installing efficiency of the PC prefabricated part can be significantly improved, the construction intensity is reduced, and the safety of construction personnel can also be ensured.

Description

technical field [0001] The invention relates to the technical field of building auxiliary equipment, in particular to an installation aid for a PC prefabricated component in a house and a method for installing the PC prefabricated component. Background technique [0002] With the gradual improvement of national building standards, more and more buildings are constructed using retarded concrete prefabricated components (abbreviated as PC prefabricated components, hereinafter collectively referred to as PC prefabricated components). Houses built with PC prefabricated components have high strength and High construction efficiency; [0003] In the prior art, the PC prefabricated components are pre-prepared in the preparation factory according to the design size, and the prepared PC prefabricated components are transported to the assembly location, and installed by a crane, combined with figure 1 and figure 2 As shown, the key to realizing the splicing of two PC prefabricated ...

AI Technical Summary

Problems solved by technology

[0004] When installing PC prefabricated components, the difficulty mainly lies in the alignment of the pre-embedded steel bar a and the pre-embedded hole b. In the prior art, only manual methods can be used to adjust the pre-assembled PC prefabricated component B and swing it on the crane until it is adjusted to The alignment of the pre-embedded steel bar a and the pre-embedded hole b can ensure the smooth assembly of the pre-assembled PC prefabricated component B. During manual work, only auxiliary equipment can be used to adjust the position of the pre-assembled PC prefabricated component B. The weight of the prefabricated components is relatively large, and the inertial force when they swing will have a great impact on the personal safety of the operators, and it will take a lot of time to achieve the alignment of the pre-embedded steel bar a and the pre-embedded hole b during actual assembly; After assembly, the pre-assembled PC prefabricated component B sometimes cannot ensure the flatness with the basic PC prefabricated component A, and the pre-assembled PC prefabricated component B may still be inclined. In the prior art, the on-site measurement of the elevation control line and the The method of laying and stuffing steel plates to adjust the installation elevation of prefabricated components is extremely inefficient, and it is necessary to dismantle the bedding and filling steel plates, resulting in extremely poor flatness of assembled PC prefabricated components
