Problems solved by technology

consumables, effort, discount
[0006] 2. Construction operability is difficult
During the construction process, workers have a very narrow operating space when erecting such formwork, and sometimes erect it from one side to the other. If there are omissions or defects, it is quite difficult to add or reinforce them later.
[0008] 3. Large material loss
[0010] 4. High labor consumption
The transfer beam is characterized by large spans and high floors, so a large amount of materials used in the erection of the formwork are manually transported, resulting in huge labor consumption
[0012] 5. Heavy inspection workload
[0014] 6. Poor overall stability
[0015] From the perspective of the overall formwork system, its stability is poor in the case of large-span and high-floor working conditions
[0016] 7. Long construction period
[0017] Due to the large amount of materials used and the large amount of labor required for the long-span transfer beam formwork system, the construction period is directly lengthened, which is unfavorable in today's era of rapid economic development.

Embodiment 1

[0057] like Figures 1 to 9As shown, the application method of the steel composite support system in the ultra-large-span conversion beam formwork system includes the following steps:

[0058] a. Measurement and positioning, locate the basement structural column on the first floor structural slab, and pop up the control line, lead the measurement of the reference elevation line, and prepare for the various components in the support system;

[0059] b. Set up column piers, set concrete column piers on the top of the basement structural columns at the middle of the transfer beam and at the support, increase the stress area of ​​the steel support columns on the structural column tops, and use the same concrete strength as the basement structural columns for the column piers, Double-layer two-way steel bars are arranged inside;

[0060] c. Set up a sand box, and set a sand box on the pier. The sand box is welded with steel plates according to the actual situation on site, and fil...

Abstract

The invention discloses a method for applying steel combined support systems to super-long-span conversion beam form erecting systems. The method includes steps of a, carrying out measuring and positioning; b, arranging piers; c, arranging sand boxes; d, arranging section steel support pillars; e, arranging section steel beams; f, arranging small transverse beams; g, laying formworks; h, pouring conversion beam concrete; i, detaching section steel support systems. The method has the advantage that the shortcomings of high material consumption, material loss, labor amount, operational difficulty and risks and long erecting cycles due to the traditional construction processes for erecting steel pipe scaffolds can be overcome by the aid of the method.

Description

technical field [0001] The invention relates to the technical field of construction in the construction engineering industry, in particular to an application method of a steel composite support system in a super-large-span transfer beam formwork system. Background technique [0002] In the ultra-large width conversion beam formwork support system, the steel pipe scaffolding is usually used as the support, and the spacing of the vertical poles is determined after detailed calculation. Usually, the calculated vertical pole spacing will be relatively dense, and the operability of the erection in the actual construction process is difficult; in order to ensure For the stability of the entire formwork system, it is necessary to repeatedly check the tightening degree of the fasteners after the erection is completed, which greatly increases the workload of on-site construction inspections; in addition, the bearing capacity of the foundation must be calculated. Usually, the structure...
