Support system

Abstract

The invention discloses a support system. The support system is suitable for temporary support for a concrete building structure post-cast strip and other structural systems with certain strength and comprises the two main components of a pipeline and a sandbox. The support system formed by the pipeline and the sandbox is adopted, thus a formwork support can be dismantled in time after the strength of the post-cast strip area structure reaches the standard strength, the lease expense of the formwork support is reduced, and the influence on a post-cast strip cantilever area structure during dismantling of the formwork support is relieved. In addition, the height of the support system can be adjusted precisely by adjusting the filling height of particulate matter in the sandbox, and the effect that a main beam and a secondary beam in the post-cast strip support area are supported on the support system precisely is ensured. The support system provided by the invention is convenient to install, dismantle and recycle, the work efficiency is improved, construction space is increased for subsequent construction of the post-cast strip support area, and the construction influence is reduced.

Description

technical field [0001] The invention relates to the technical field of post-cast belt area construction of building structures, in particular to a support system. Background technique [0002] In building construction, in order to prevent the possible harmful cracks caused by the shrinkage of the reinforced concrete structure or uneven settlement, according to the design and construction requirements, it is necessary to set up temporary construction joints in areas such as concrete beams and slabs, that is, post-casting belts. There are four types: settlement post-casting tape, shrinkage post-casting tape, temperature post-casting tape and telescopic post-casting tape. Among them, the temperature post-casting belt is generally closed within 1-2 months after the construction of the structure in this area; the post-settling post-casting belt can generally be closed 45 days after the structure is capped. Since only the calculation of the overall force is considered in the prof...

Problems solved by technology

Most of the supporting tops are in the form of steel pipe bent frames. During the construction process, the removal of the formwork supports and the construction overlap of the tops need to be strictly controlled. Disturbances during the demolition process may have adverse effects on the structure. At the same time, a bent system is set up in this area. It also takes up a lot of space, which will have a certain impact on subsequent professional construction
