Problems solved by technology

For the basement and the first to fifth floors of 1200X1200 large-section frame columns, the rigidity of the outer corrugation of the steel pipe of the ordinary formwork system is not enough, and the repair of holes caused by pulling the screw through the center will affect the appearance. In order to ensure the molding size and appearance of the column concrete, the formwork reinforcement system needs to be improved

Embodiment Construction

[0028] From Figure 1 to Figure 4 Visible, main implementation steps of the present invention are:

[0029] 1. Template design:

[0030] 1) According to the form, characteristics and site conditions of the project structure, reasonably determine the flow section of the formwork construction to determine the most economical formwork input, increase the number of turnovers, and balance the workload of the process engineering (reinforcement, formwork, concrete process) ;

[0031] 2) Calculate the column model, quantity, size and height according to the drawings, and number the replacement relationship and number of the same or slightly patched components, so as to reduce the type and quantity of matching plates and clarify the replacement flow direction and position of the formwork;

[0032] 3) Determine the plane layout and support layout of the column formwork: design the mold matching diagram according to the column size and number, mark the size of each formwork and its pl...

Abstract

A reinforcing method for U-bar hoop formworks of a large-section frame column mainly comprises the implementation steps of 1, formwork design and checking calculation, 2, formworks arrangement, numbers giving and piling; 3, U-bar hoop processing, 4, pull screw manufacture, 5, column axis determination and elevation measurement, 6, column root formwork processing, 7, quality inspection, 8, erection of a support frame body, and 9, installation of the column formworks. The reinforcing method for U-bar hoop formworks of a large-section frame column fully utilizes rigidity and strength of U-bars, effectively controls section deformation of the frame column, avoids influence on building appearance quality caused by holes formed by penetrating the penetrating pull screws through components, solves the quality problems of jig displacement, formwork expansion, slurry leakage and the like to some extent, and meanwhile reduces use quantity of fasteners. All the construction materials can be reused, and cost is saved. The reinforcing method for U-bar hoop formworks of the large-section frame column is simple to operate and simple and easy in procedure, not only effectively shortens construction periods, improves quality and saves the cost, but also is simple in process, practical and reliable.

Description

technical field [0001] The invention relates to a formwork reinforcement technology for high-rise and super high-rise buildings, in particular to a formwork reinforcement method for a large-section frame column with a cross-section above 1000*1000. Background technique [0002] The conventional frame column formwork installation project adopts the outer hoop of the steel pipe and the center-piercing reinforcement of the pull screw. This reinforcement method is cumbersome, consumes a lot of turnover materials, and the appearance is ordinary after pouring. Especially for frame columns with a large cross-sectional area, due to the large lateral pressure during the concrete pouring process, the outer hoop of the steel pipe is very large, and a large number of fasteners need to be installed to match it. The process is cumbersome and affects the construction progress; The amount of screw used is large, resulting in many holes on the concrete surface that need to be repaired after ...
