Construction method of constructional column after completion of secondary masonry structure

Abstract

The invention discloses a construction method of a constructional column after the completion of secondary masonry structure. A formwork device comprises a shaped steel formwork, square pipes, split bolts, a sealing pad and fixing pins, the shaped steel formwork is integrally in a U shape and comprises two side plates and an end plate connected between the ends of one sides of the two side plates,and a plurality of split bolt holes are correspondingly formed in the two side plates of the shaped steel formwork in the height direction. The square pipes are correspondingly arranged on the outerside of each side plate, bolt holes corresponding to split bolt holes in the side plates are formed in the square pipes, the square pipes on the two sides and the side plates are connected through thesplit bolts, the two fixing pins are correspondingly arranged at the upper ends and the lower ends of the square pipes, and one ends of the fixing pins are fixed to a cast-in-place floor slab. A feeding port is fixedly connected to the upper part of the end plate of the shaped steel formwork, and when the formwork is installed, the side plates on the two sides of an opening end of the shaped steel formwork are correspondingly in lap joint with the outer side of the secondary masonry structure. According to the construction method of the constructional column after the completion of the secondary masonry structure, the appearance quality of the constructional column is improved, and disturbance to completed brickworks is reduced.

Description

technical field [0001] The invention relates to a construction method of a structural column after a secondary masonry structure is completed, and belongs to the technical field of building construction. Background technique [0002] At present, in the field of high-rise and super-high-rise building construction, wooden formwork is usually used as the formwork for pouring in the construction of structural columns after the completion of secondary structure masonry, and the main and secondary keels are made of wood. Factors lead to irregular placement of wooden squares, which in turn lead to appearance quality defects such as mold expansion, non-vertical male corners, slippage, and size deviation of the structural columns, and this formwork device cannot be reused, which increases construction costs, and this construction method In the secondary structure wall after the masonry is completed, it is necessary to set up the tension bolt holes to install the tension bolts, which ...

[0002] At present, in the field of high-rise and super-high-rise building construction, wooden formwork is usually used as the formwork for pouring in the construction of structural columns after the completion of secondary structure masonry, and the main and secondary keels are made of wood. Factors lead to irregular placement of wooden squares, which in turn lead to appearance quality defects such as mold expansion, non-vertical male corners, slippage, and size deviation of the structural columns, and this formwork device cannot be reused, which increases construction costs, and this construction method In the secondary structure wall after the masonry is completed, it is necessary to set up the tension bolt holes to install the tension bolts, which will damage the completed masonry and easily cause disturbance of the completed masonry when vibrating the concrete, which will affect the secondary structure in severe cases.
