Problems solved by technology

The disadvantage of this method is that there are too many turnover materials on both sides of the post-casting belt, resulting in increased costs; secondly, it is difficult to control the demolition of the formwork, and the control is not strict. The structure is cracked and there are hidden dangers to safety and quality; third, the formwork is supported first, the loo

Embodiment 1

[0023] Preferred embodiment one, such as figure 1 , figure 2 As shown, the present invention is used for the construction of a reinforced concrete slab support system without beams and with post-cast belts. Its construction steps are as follows:

[0024] First set up the main formwork support system: it includes the support frame body A standing on the ground or the floor and the support corrugated system B arranged horizontally on the support frame body A. The support frame body A is a support pole 10 and a horizontal connecting rod 12 through steel A support formwork frame system formed by a connection method of fastener type, disc buckle type or bowl buckle type. The top of the support pole 10 has an adjustable jacking 1, and the support flute system B includes the main flute 5 and the secondary flute 6. The secondary flute 6 is evenly arranged on it perpendicular to the main flute 5. Both the main flute 5 and the secondary flute can be made of wooden squares, square ste...

Embodiment 2

[0032] Preferred embodiment two, such as image 3 , Figure 4 As shown, the present invention is used for the beam-slab support system construction of the post-cast belt with beams passing through. The basic construction steps are the same as the previous embodiment, except that the supporting position of the supporting lattice column is at the end of each beam near the rear pouring belt.

Abstract

The invention discloses a beam plate post-cast strip template support system and a construction method, wherein a main template support body supports all beam plates arranged at two sides of a post-cast strip, and support latticed columns are independently supported at two sides of the post-cast strip. After the main template support body is built, and when bottom templates of the beam plates are paved, the post-cast strip is unavailable without installation. When the main template support body is built, the bottom templates can be wholly paved, or the support latticed columns can be independently paved, so that the construction speed can be accelerated; the independent latticed column is convenient to uniformly set and wholly distribute; the whole template of a main template support system can be disassembled, and only the latticed columns can be remained to support, so that the mass of revolving materials can be saved, and the inconvenient material transportation traffic caused by the isolation and division of a post-cast strip-supported mould base in a basement can not be avoided; and before the concrete arranged at two sides of the post-cast strip is cast, the region is convenient and thorough to clean, and the construction quality of the post-cast strip can be preferably guaranteed.

Description

technical field [0001] The invention relates to a construction method of a formwork support system in construction engineering, in particular to a formwork support system and a construction method of a beam-slab post-cast belt formwork support system. Background technique [0002] At present, with the continuous development of society, super-long concrete structures continue to appear in construction projects. In order to solve the settlement differences between the high-rise main body and the skirt room, the shrinkage and deformation of reinforced concrete, and the temperature stress of concrete, according to the requirements of the code, every 30~ A post-casting belt is set at 40m. Since the formwork system at the post-casting zone is strictly prohibited from going back to the top, the traditional construction method supports the entire beam-slab formwork (including the position of the post-casting zone) as a whole or separately within 2 to 3 meters on both sides of the po...
