A high-quality prefabricated column preparation process

Abstract

The invention discloses a manufacturing process of a high-quality prefabricated column. The manufacturing process comprises a mold table used for building a mold, two side mold plates, two end mold plates, at least four main reinforcements used for prefabricating, a plurality of stirrups and a plurality of sleeves. The main reinforcements comprise upper-layer reinforcing steel bars, and holes arranged in the side mold plates and the end mold plates are detected through a measuring device. The manufacturing process comprises the following steps of 1) detecting mold plates; 2) assembling the side mold plates and binding a reinforcement cage; 3) hoisting the reinforcement cage; 4) assembling the end mold plates; 5) detecting splicing quality; 6) adjusting the upper-layer reinforcing steel bars, hoisting the main reinforcements at a standard position by adopting a hoisting steel wire, making mark points through the hoisting steel wire, and marking two mark points on the hoisting steel wireaccording to a distance between a hoisting device and the main reinforcements; 7) pouring concrete; 8) dismounting the steel wire; and 9) dismounting the mold to obtain a finished product. In the invention, quality of the prefabricated column can be effectively improved, and product quality is guaranteed.

Description

technical field [0001] The invention relates to the technical field of prefabricated component preparation, in particular to a high-quality prefabricated column preparation process. Background technique [0002] PC components have many advantages such as high efficiency and energy saving, green environmental protection, cost reduction, and providing functions. In recent years, various new construction concepts such as construction industrialization, energy saving and emission reduction, quality safety, and ecological environmental protection have brought development opportunities for PC components. In the process of urbanization, a large number of infrastructure constructions, large-scale affordable housing urgently need standardization, rapid construction and high Quality construction provides a wide space for PC components. [0003] Since PC components are all prefabricated structures, the quality of the components determines the quality of the building. As the core forc...

Problems solved by technology

However, since the main reinforcement on the top surface of the prefabricated column is only fixed at both ends and assisted by stirrups, the actual situation cannot prevent the serious downward deflection problem in the middle of the main reinforcement caused by the large length and large diameter, and the maximum deviation on site can reach 10mm~ 20mm, when the prefabricated column is being poured, the top forming surface, especially the reinforcement protection layer in the middle, is seriously too large, which may directly lead to the failure of component inspection and acceptance

What's more serious is that the prefabricated column is an axial compression member, and the arc-shaped bending of the main reinforcement may cause the load to fail to transmit force along the axial direction of the main reinforcement, resulting in a tendency for the structure to become unstable, burying serious safety hazards
