Spanning type formwork supporting system

Abstract

The invention relates to a spanning type formwork supporting system. The system comprises a foundation pit, a raft foundation is laid on the bottom surface of the foundation pit, a revetment is laid on the slope surface of the foundation pit, the upper end of the revetment extends to the top surface of the foundation pit to form a revetment flange, and an I-shaped steel platform is erected betweenthe revetment flange and the raft foundation. The I-shaped steel platform comprises bedding I-shaped steel, a plurality of sets of supporting frames and straight steel bars. The upper ends of the supporting frames are erected on the bedding I-shaped steel. The straight steel bars are welded among the supporting frames, and a plurality of steel bar supporting legs are further arranged at the upperends of the supporting frames. A steel pipe diagonal bracing is welded between every two adjacent groups of supporting frames. Full support frames are erected on the I-shaped steel platform and the raft foundation. According to the system, the flat I-shaped steel platform is erected above a height difference area and a area crossing the foundation pit supporting slope so that the I-shaped steel platform can be used as a flat foundation of the formwork supporting system or a tall and big formwork supporting system.

Description

technical field [0001] The invention relates to the technical field of building construction, in particular to a spanning formwork support system. Background technique [0002] In the process of engineering construction, it is inevitable to encounter the situation of erecting support frames under various circumstances. The foundation of the common formwork support system is required to be flat and solid. Take about 900mm, which needs to be determined by calculation; however, because the current building types are developing in the direction of tall, large, refined, and sharp, there are always some special parts that need to be erected with special formwork support systems, and even erect tall formwork under special conditions. Support system, such as stadium buildings, the more common building structure is the type with small bottom and large top. The upward floor will have structural external cantilever members protruding from the edge of the lower floor, which requires the...

AI Technical Summary

Problems solved by technology

[0004] In order to solve the problem that there is no flat foundation at the bottom of the full house support frame and it is inconvenient to erect when crossing a large height difference area and a foundation pit support slope area, the present invention provides a spanning formwork support system. Set up the I-beam platform, which can be used as a formwork support system or a flat foundation for a tall formwork support system
