Constructing method for prefabricated constructional column

Abstract

The invention discloses a constructing method for a prefabricated constructional column. The constructing method for the prefabricated constructional column adopts a partial prefabricated method, a section of constructional column mould shell is prefabricated first, and then bar planting holes are drilled on an upper beam and a bottom plate correspondingly; a fixing steel bar is planted in each bar planting hole on the bottom plate, and a steel bar at the upper end of the prefabricated constructional column mould shell is inserted into the bar planting hole of the upper beam and filled with bar planting glue for fixing; the upper end of the prefabricated constructional column mould shell is abutted against the upper beam, and a steel bar at the lower end of the prefabricated constructional column mould shell is fixed to the fixing steel bar in a binding mode; and next outward bricklaying is conducted from the two ends of the prefabricated constructional column mould shell, and then a mould plate is arranged under the prefabricated constructional column mould shell in a supporting mode; and concrete is poured from a concrete pouring port on the prefabricated constructional column mould shell, and a formwork can be disassembled after the concrete is solidified. According to the constructing method for the prefabricated constructional column, based on the traditional constructing technology, constructing technology procedure of the constructional column is optimized and improved, partial prefabricating and partial on-site pouring methods are adopted, using quantity of the mould plate during constructing process of the constructional column is greatly saved, and constructing period is saved.

Description

technical field [0001] The invention relates to a construction method of a structural column, in particular to a construction method of a prefabricated structural column. Background technique [0002] The frame structure has the advantages of flexible space separation, light weight, and material saving; it can be more flexibly matched with the layout of the building, and is widely used in residences, schools, office buildings, etc., and can also be prestressed on concrete beams or slabs as required For larger spans. After the construction of the main body of the frame structure is completed, the way of filling walls is usually used to realize the functions of space separation and enclosure. In order to improve the overall rigidity and ductility of the building, restrict the development of cracks in the wall, increase the stability of the building, and strengthen the earthquake resistance of the building, it is required to set up secondary pouring structural columns in the f...

AI Technical Summary

Problems solved by technology

The construction process is cumbersome, the amount of formwork used is large, the amount of labor is large, and the construction period is long

During the construction process, due to the small size of the structural columns, it is difficult to vibrate the concrete, which leads to the inability to guarantee the quality of the concrete pouring, and the quality of the perception is poor. When the storey height is high, the structural columns need to be poured in sections, which makes the construction more difficult
