Abstract

The invention provides a preloading structural part for a high and large formwork support system, which is used for solving the technical problems caused by preloading detection using sandbags or concrete blocks. The preloading structural part comprises a brick pier component and preloading components, wherein the brick pier component consists of a first brick pier block and a second brick pier block; a first floating layer is arranged at the top of the first brick pier block; a second floating layer is arranged at the top of the second brick pier block; the top surface of the first floating layer is level with the top surface of the second floating layer; each preloading component consists of 2-10 preloading units in horizontal arrangement; the preloading components are piled at the top of the brick pier component layer by layer; and 2-20 layers of preloading components are paved at the top of the brick pier component. The preloading structural part provided by the invention has the beneficial effects that a relatively large unit area load can be obtained under the condition of relatively low loading height so as to reduce the height of a preloading body and the hoisting workload of the preloading body and guarantee high safety.

Description

technical field [0001] The invention belongs to the field of building construction, and in particular relates to a surcharged preloaded structural member used for a tall formwork support system. Background technique [0002] With the continuous development of social economy, architectural design is constantly developing towards large span and large space, and the design and application of cast-in-situ beams and slabs with super large cross-section and super long span are becoming more and more frequent. For the formwork support system of reinforced concrete beams and slabs with large cross-sections during construction, in order to verify the strength, stiffness and stability of the formwork support system and eliminate the adverse effects of elastic and plastic deformation of the support system and foundation, it is often necessary to pour concrete The formwork support system of the reinforced concrete beam slab is preloaded and preloaded to ensure the safety and stability o...
