Suspension type prepressing structure and using method thereof

Abstract

The invention discloses a suspension type prepressing structure and a using method thereof. The suspension type prepressing structure comprises a cantilever type support, a hanging basket arranged at the free end of the cantilever type support and a stacking water bag arranged in the hanging basket; the stacking water bag is arranged on the bottom face of the inner surface of the hanging basket; the hanging basket is provided with a guardrail surrounding the stacking water bag; and a plurality of hooks are arranged on the lower surface of the hanging basket and connected with a plurality of suspension water bags. The suspension type prepressing structure has the beneficial effects that according to the scheme, the stacking water bag and the suspension water bags are used for providing loads at the same time, the number of the suspension water bags can be controlled according to needs, and therefore the magnitude of the loads is controlled; the suspension type prepressing structure has the advantages of being high in adjusting precision, convenient and flexible to use and the like; and water resources in the water bags can be repeatedly used, the construction cost can be reduced, and building rubbish is reduced.

Description

technical field [0001] The invention relates to the technical field of construction, in particular to a suspended preloaded structure and its application method. Background technique [0002] The preloading work of the bracket formwork system is an important link in the construction. It is an early inspection of the formwork bracket, eliminates the inelastic deformation, obtains the elastic deformation, and provides a basis for subsequent construction. The choice of preloading process not only needs to simulate the real stress state, but also relates to the construction schedule and cost. [0003] At present, most of the formwork support systems such as pipe column supports, brackets, hanging baskets, and hoops used in the construction of structures in my country are preloaded by concrete preloaded block surcharge preload, ordinary water bag surcharge preload, and reaction frame preload. In actual operation, the above preloading methods have several disadvantages: 1. Preload...

Problems solved by technology

[0003] At present, most of the formwork support systems such as pipe column supports, brackets, hanging baskets, and hoops used in the construction of structures in my country are preloaded by concrete preloaded block surcharge preload, ordinary water bag surcharge preload, and reaction frame preload. In actual operation, the above preloading methods have several disadvantages: 1. Preloading preloading of prefabricated concrete blocks requires high site requirements, low work efficiency, and time-consuming and laborious; 2. The preloading preloading of ordinary water bags is a uniform load. , it is impossible to simulate the real situation of part of the concentrated load support formwork; 3. All the preloads of the reaction frame are concentrated loads, which cannot effectively preload the entire support formwork system
