Abstract
The invention relates to a method for constructing a steel-skeleton prestressed reinforced concrete building, which is characterized in that three-dimensional connecting parts are welded at both ends of a steel pipe, reinforced bars which are threaded at both ends penetrate through corresponding reinforced bar punch holes of the three-dimensional connecting parts welded at both ends of the steel pipe and are screwed up by nuts to enable the reinforced bars to be prestressed; and the three-dimensional connecting parts can be interconnected with steel pipes and reinforced bars in each direction of three dimensions with the same method to form an integral steel structure inside the concrete building which comprises the steel pipes, the three-dimensional connecting parts and the prestressed reinforced bars, and then, a formwork is erected on site for integral concrete pouring. The method is especially applicable to the buildings in the earthquake-prone areas.
Description
One, technical field
The present invention relates to a kind of building structure method of steel-skeleton prestressed reinforced concrete.
Two, background technology
Because prestressed reinforced concrete can improve the intensity of steel concrete, can well strengthen the shock resistance of building, as members such as the post of building, Beam are interconnected to whole back cast-in-place concrete with prestressed reinforcement, the rigidity of the intensity of building member and whole building structure has just had better guarantee so.
Purpose of the present invention is exactly for members such as the post of realizing building, Beam connect into whole back cast-in-place concrete with prestressed reinforcement, strengthens the intensity and the integrally-built rigidity of building member, reaches the purpose that improves the Antiseismic building performance.
Three, summary of the invention
The building structure method of steel-skeleton prestressed reinforced concrete of the present invention is to realize by such technical scheme:
Three-dimensional prestressed reinforcement connecting elements (being called for short three-dimensional connector) is welded at the steel pipe two ends, to twist threaded reinforcing bar by the two ends of design quantity and from the corresponding reinforced steel bar perforation of the three-dimensional connector of steel pipe two ends welding, pass outer rear flank respectively and screw, make reinforcing bar acquisition prestressing force with nut; Three-dimensional connector can be used with quadrat method with the steel pipe of three dimension all directions and reinforcing bar and interconnect, and makes the steel work of the concrete construction inner body of being made up of steel pipe, three-dimensional connector, prestressed reinforcement, and then the integrated poured concrete of on-the-spot formwork.
Four, description of drawings
Fig. 1 is the overall structure schematic diagram of the building structure method of steel-skeleton prestressed reinforced concrete;
Fig. 2 is the local connection diagram of three-dimensional connector and steel pipe, prestressed reinforcement;
Fig. 3 is three-dimensional connector elevation;
Fig. 4 is each model shape figure of steel tube end part;
Wherein: 1, steel pipe, 2, three-dimensional connector, 3, two ends twist threaded reinforcing bar, 4, nut, 5, reinforced steel bar perforation, 6, the concrete flow through hole.
Five, specific implementation method
The advantage of the building structure method of steel-skeleton prestressed reinforced concrete of the present invention is: be interconnected to whole prestressed reinforcement because each component inside of concrete structure all has by three-dimensional connector, and in the middle of prestressed reinforcement, also have and be interconnected to whole steel pipe simultaneously by three-dimensional connector, form the steel work of the inner complete integral body of forming by steel pipe " skeleton " and prestressed reinforcement of concrete structure, increased the intensity and the integrally-built rigidity of concrete construction component of thing greatly.
The embodiment of the invention is described further in conjunction with the accompanying drawings.
As shown in the figure: steel pipe
1Three-dimensional connector is welded at two ends
2, will twist threaded reinforcing bar by the two ends of design quantity
3Respectively from steel pipe
1The three-dimensional connector of two ends welding
2Corresponding reinforced steel bar perforation
5In pass outer rear flank nut
4Screw, make steel pipe
1Reinforcing bar on every side
3Obtain uniform prestressing force; According to the needs of design, three-dimensional connector
2Can with the steel pipe of all directions of three dimensions
1And reinforcing bar
3With interconnecting, make by steel pipe with quadrat method
1, three-dimensional connector
2, prestressed reinforcement
3The steel work of the concrete structure inner body of being formed, and then the integrated poured concrete of on-the-spot formwork.
The building structure method of steel-skeleton prestressed reinforced concrete of the present invention is applicable to all buildings such as house, bridge, is applicable to the building of earthquake prone areas especially.
