Description
Technical Field
The invention relates to the technical field of steel plate concrete composite wall structures of nuclear power stations, in particular to a steel plate concrete composite wall counter-pulling system with compression resistance and no transmission pulling.
Background
In the structural design and construction process of the steel plate concrete composite wall of the nuclear power station, a steel plate concrete composite wall opposite-pulling system is an important component for ensuring the combination stress of a steel panel and core concrete. The opposite-pulling system generally adopts a truss structure composed of opposite-pulling reinforcing steel bars or stiffening ribs, profile steels, opposite-pulling steel slabs and the like. Because a general counter-pulling system is subjected to double restraint of steel panels on two sides and inner core concrete, tensile force and pressure can be transmitted between the steel panels, and when one side of a steel plate concrete composite wall of a nuclear power station is subjected to a missile impact load, the stress state of the counter-pulling system needs to be compression-resistant and non-transmission-pulling in order to resist damage, but the stress requirement of compression-resistant and non-transmission-pulling under the missile impact load cannot be met by the general counter-pulling system at present, so the steel panels on two sides are often damaged, and the service life of the steel panels is shortened.
Therefore, how to provide a steel plate concrete composite wall that nuclear power station steel plate concrete composite wall can normally bear under the shock load of shooting, guarantee that both sides steel decking are not impaired, prolong the life of steel decking's resistance to compression does not pass the steel plate concrete composite wall to drawing the system is the problem that technical staff in the field need solve urgently.
Disclosure of Invention
In view of the above, the invention provides a counter-pulling system of a steel plate concrete composite wall, which is used for the nuclear power station and has the advantages that the steel plate concrete composite wall can normally bear the load under the impact load of the fire, the steel plate panels on two sides are not damaged, and the service life of the steel plate panels is prolonged.
In order to achieve the purpose, the invention adopts the following technical scheme:
the utility model provides a steel sheet concrete composite wall counter-pulling system that resistance to compression does not pass and draws, includes:
the steel pull rods are arranged in the concrete in rows and columns, two ends of each steel pull rod penetrate through the two steel face plates which are arranged oppositely, fastening nuts are respectively screwed at two ends of each steel pull rod, and spring gaskets are pressed between the fastening nuts and the steel face plates;
the steel sleeve is provided with a plurality of steel sleeves which are respectively sleeved on the corresponding steel pull rods, and two ends of each steel sleeve are in contact with the inner walls of the two steel panels.
According to the technical scheme, compared with the prior art, the invention discloses the steel plate concrete combined wall opposite-pulling system which is resistant to compression and does not transmit pulling, and under the action of external impact load, the steel sleeve is relatively high in axial rigidity and only contacts with the steel panels but is not welded and fixed, so that the pressure between the steel panels on two sides can be effectively transmitted. Because the spring gasket is added between the steel pull rod and the steel panel, certain pulling force can be provided in the construction of pouring inner core concrete, but under the action of external impact load, the spring gasket can generate certain deformation, so that the steel pull rod can release the inner pulling force between the steel panels at two sides. Therefore, the invention can completely transmit the pressure between the steel panels on the two sides of the steel plate concrete composite wall and effectively release the tension between the steel panels on the two sides, thereby greatly reducing the damage of external impact load to the steel panels and being an effective supplement to the common counter-pulling system adopted by the steel plate concrete composite wall of the nuclear power station at present.
Furthermore, a polytetrafluoroethylene material is filled between the steel sleeve and the steel pull rod. The friction between the steel sleeve and the steel pull rod can be reduced, the axial movement of the steel pull rod is easy, the deformation of the spring gasket is convenient, and the steel pull rod can release the internal tension between the steel panels on two sides.

All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
The embodiment of the invention discloses a steel plate concrete composite wall counter-pulling system with compression resistance and no transmission of pulling, which comprises the following components:
the concrete structure comprises steel pull rods 1, wherein the steel pull rods 1 are arranged in the concrete 100 in rows and columns, two ends of each steel pull rod 1 penetrate through two steel face plates 200 which are arranged oppositely, two ends of each steel pull rod 1 are respectively screwed with fastening nuts 2, and spring gaskets 3 are pressed between the fastening nuts 2 and the steel face plates 200;
