Limited space structure preloading construction method

Abstract

The invention provides a limited space structure preloading construction method, which comprises the following steps of: erecting a to-be-preloaded structure bracket, and mounting a template; erectinga pre-loading stacking platform above the to-be-pre-loaded structure, installing a conveying device, and enabling the two ends of the conveying device to communicate with the inner side of the formwork and the pre-loading stacking platform correspondingly; transporting the pre-loaded material to the pre-loaded material stacking platform; and conveying the pre-loaded material to the inner side ofthe template through the material conveying device to complete preloading, erecting the pre-loaded material stacking platform to stack the loading material at the position, convenient to operate, of the to-be-preloaded structure, and transferring the pre-loaded material into the template of the to-be-preloaded structure through the material conveying device, so that convenience is achieved, and the quality is controllable.

Description

technical field [0001] The invention belongs to the technical field of building construction, and in particular relates to a preloading construction method for a structure in a limited space. Background technique [0002] Reinforced concrete (English: Reinforced Concrete or Ferroconcrete), engineering is often referred to as reinforced concrete (tong). It refers to a composite material that works together to improve the mechanical properties of concrete by adding steel mesh, steel plates or fibers to the concrete. It is the most common form of reinforced concrete. [0003] At present, in China, reinforced concrete is the most widely used structural form, accounting for the vast majority of the total. At the same time, China is also the region that uses the most reinforced concrete structures in the world. [0004] Reinforced concrete structure buildings refer to buildings in which most of the main load-bearing components are made of reinforced concrete, including beams, co...

AI Technical Summary

Problems solved by technology

[0004] Reinforced concrete structure buildings refer to buildings in which most of the main load-bearing components are made of reinforced concrete, including beams, columns, floors, roof panels, stairs and foundations; in addition, some reinforced concrete structures are commonly used to connect Beams and connecting beams are a form of connection between structural members under stress. They generally do not participate in structural calculations, and are often set according to regulations or experience. Usually, this part of the structure needs to be preloaded. Test, among them, Some structural components are limited by the construction environment, or are affected by existing buildings, or are affected by the previous construction structure, so the preload test cannot be completed conveniently
