[0002] At present, the pouring of the concrete floor of the nuclear power plant adopts the traditional method of scaffolding and temporary support. This method has an obvious disadvantage for the progress of the project, that is, the introduction of equipment can only be carried out after the concrete is completely cured and the scaffolding and formwork are removed. , sometimes this waiting time takes more than ten months, which seriously prolongs the construction period
In addition, the introduction of equipment after construction requires planning the hoisting route, setting up hoisting holes and transportation channels, etc., which requires a lot of manpower and material resources

Embodiment
[0022] Taking the nuclear power plant building as an example, the rapid support method for the floor construction of reusable nuclear power plant once-introduced equipment is introduced.
[0023] Such as figure 1 , figure 2 As shown, in the workshop room of the nuclear power plant, shaped steel columns 1 are arranged close to the surrounding walls, and the steel columns 1 are set to a full height under the condition that the space of the formwork 5 at the bottom of the floor is reserved. The gusset plates 3 are preinstalled in different directions on the top of the steel column 1. The gusset plate 3 is an angle steel, one leg is connected to the steel column 1, and the other leg is connected to the steel beam 2 through the bolt 4, the details of the joint are as follows image 3 , Figure 4 shown. If the span of the room is large, steel columns 6 can be set in the middle of the room to reduce the supporting span without affecting the introduction of equipment. The steel ...

The invention belongs to the design technology of a building structure, and particularly relates to a floor construction rapid support method capable of being reused. The floor construction rapid support method comprises the steps that temporarily supported steel columns are arranged near walls of the periphery of a workshop room to be constructed, joint plates are preinstalled on the end portionsof the steel columns, steel beams are connected between the steel beams through the joint plates, and a steel frame system is integrally formed; and templates are laid on the steel beams of the steelframe, and a concrete floor is poured. The steel frame system formed by the steel beams and the steel columns can effectively support the load of upper floor construction, thus replacing the functionof a traditional scaffold. The steel columns of the steel frame are arranged by the side of the walls, and the steel beams are arranged by the floor bottom, so that the main space in the room is notaffected, and equipment can be introduced in advance. The floor construction rapid support method capable of being reused can shorten construction period, improves production efficiency and reduces construction cost.
