Problems solved by technology

[0003] The present invention solves the problem that large-scale tank structures in energy engineering adopt prestressed reinforced concrete structures, which easily cause positioning deviations and affect their overall mechanical performance. The construction is difficult, the cycle is long, and the cost is high. When the steel plate-concrete composite structure is used for on-site construction , the internal space of the structural module unit is narrow, the steel pipes are dense, the steel plate side pressure requirements are strict, and the deformation control is difficult. There are difficulties in on-site concrete pouring, so its overall mechanical performance will also be adversely affected. In order to provide an assembly Type tank steel plate-concrete composite member and its construction method

Abstract

The invention relates to an assembly type tank steel plate-concrete combined member and a construction method thereof. The assembly type tank steel plate-concrete combined member and the construction method thereof aim at solving the problems of influence to whole stress property due to positioning deviation caused by large tank structure, high difficulty in construction, long cycle, and high manufacturing cost; narrow internal space of structure modularizing unit, dense reinforcement pipelines, strict requirement on side pressure of steel pipes, high difficulty in deformation control and the like in the energy source engineering; because of difficulty in casting of cast-in-situ concrete, the whole stress property also suffers from adverse effect. The assembly type tank steel plate-concrete combined member comprises an outer steel plate, an inner steel plate, concrete blocks, tie bar assemblies, fixed bolts and bolt screws. The construction method comprises the following steps of 1, preparation of material; 2, manufacturing and processing of the edges of the outer steel plate and inner steel plate; 3, welding and fixing of bolt screws and lug plates on the outer steel plate and inner steel plate; 4, fixed connection of the outer steel plate and inner steel plate; 5, injecting of concrete. The assembly type tank steel plate-concrete combined member is applied to building construction.

Description

technical field [0001] The invention relates to a concrete composite component and its construction method, in particular to an assembled tank steel plate-concrete composite component and its construction method. Background technique [0002] For the tank structure of large-scale energy structure projects such as nuclear power plant containment and oil storage tanks, it is extremely important to ensure its structural airtightness and safety. The large-scale tank structures in existing energy projects mainly adopt prestressed reinforced concrete structures and steel plate-concrete composite structures, both of which adopt on-site construction methods. For prestressed reinforced concrete structures, due to the complex positioning of prestressed steel bars during on-site construction, it is easy to cause positioning deviations and affect its overall mechanical performance, and the on-site construction is difficult, long-term, and expensive. During on-site construction of the s...
