Abstract
The invention discloses a connecting piece for a steel box base plate of a steel box superposed beam (plate). Base plates of superposed steel box beams and plates, which are used in bridges currently, are poured from cement concrete, and relative slippage between concrete in a box cavity and metal plates arranged around the concrete happens when the structure is affected by a load, thus adverse effect is produced to the stability of the whole structure and a hidden trouble is caused. In the technical scheme of the invention, a connecting piece is arranged in a steel box base plate at the lower part of a steel box superposed beam (plate), concrete is filled around the connecting piece of the steel box base plate, the connecting piece can be directly placed into the steel box base plate to connect an upper metal plate and a lower metal plate, an assembled connecting piece is arranged in the cavity of the steel box base plate during construction, and then the concrete is poured, thus, after concrete pouring, the structure has good stability and high safety and basically no relative slippage happens.
Description
Technical field:
The present invention relates to a kind of box-beam structure, relate in particular to a kind of steel case superposed beam (plate) steel box plate connector.
Background technology:
Urban interchange is badly in need of short, little, the low cost of occupation of land of a kind of construction period, and can remove the bridge that reclaims, steel case superposed beam (plate) is because it makes that for metal and concrete combination whole production can standardized production and construction, and alleviated weight greatly, make construction easier with manufacturing, but because the metal and the concrete physical parameter of steel case superposed beam (plate) are different as the degrees of expansion after being expanded with heat and contract with cold, and it places outdoor at last, and it is many as the situations such as erosion of water therefore to be subjected to external environment.
Bridge is the cement concrete perfusion with superimposed steel case beam (plate) base plate of plate at present, there is relative slippage in its structure between the Intraabdominal concrete in case chamber and the metal sheet being subjected to making under the loading, thereby the stability of structure to integral body has a negative impact, and causes a hidden trouble.
The purpose of invention:
In order to provide a kind of difficult generation relative slippage, weight is lighter, and stability is high, safety, and a kind of steel case superposed beam (plate) steel box plate connector of constructing easily.
In order to reach as above purpose, the present invention takes following technical scheme: the inside, steel box plate abdominal cavity of steel case superposed beam (plate) bottom is provided with connector.
The further technical scheme of the present invention is: fill concrete is arranged around the connector of inside, described steel box plate abdominal cavity.
The further technical scheme of the present invention is: described connector connects the connector of metal sheet up and down for can directly being placed in the steel box plate.
In the time of construction, the connector that assembles is fit into steel box plate intraperitoneal, carries out concrete perfusion again, can be difficult for taking place relative slippage so that the structural stability behind the concrete perfusion is good, safe.
Adopt as above a kind of steel case superposed beam (plate) steel box plate connector of technical scheme, has following beneficial effect: because the connector construction easily, install simple and conveniently, make that whole box-beam structure is more stable, be subjected to after ectocine and the corresponding extruding force (load) more stable; Safety and construction easily.
And, if adopt as above technical scheme in the steel box plate 1, then its inner prestressing force can useful effect in body structure, make that the whole box body structure is more firm.

Wherein: 1. steel box plate; 2. connector; 21. floor hole; 22. truss-like connector; 23. net formula truss-like connector; 24 weldering nail interconnection system connectors.
The specific embodiment:
Below in conjunction with accompanying drawing embodiments of the invention are described, because the way of example of connector 2 is non exhaustive, so the following stated embodiment is not construed as limiting the invention, and only is used for supporting the present invention to implement;
The inside, steel box plate 1 abdominal cavity of steel case superposed beam (plate) bottom is provided with connector 2.
The further technical scheme of the present invention is: around the connector 2 of inside, described steel box plate 1 abdominal cavity fill concrete is arranged.
The further technical scheme of the present invention is: described connector 2 connects the connector 2 of metal sheet up and down for can directly being placed in the steel box plate 1.
In the time of construction, the connector that assembles is fit into the steel box plate, carries out concrete perfusion again, can be difficult for taking place relative slippage so that the structural stability behind the concrete perfusion is good, safe.
Fig. 1 is the structure schematic cross-sectional view of invention, and steel box plate 1 is positioned at its underpart, inner fill concrete.
Fig. 2-1 is for using the internal construction schematic diagram of floor cellular type connector, in the time of construction a plurality of floor cellular type connectors are filled in it, concrete is evenly distributed on wherein by floor hole 21, forms the concrete pin, thereby make to have good stability, be difficult for taking place relative slippage.
Fig. 2-2 adopts the case beam of this connector style for using the internal construction schematic diagram of truss-like connector, and structure also obtains firmly, and is difficult for taking place relative slippage.
Fig. 2-3 adopts this connector for using the internal construction schematic diagram of net formula truss-like connector, laterally with is connected longitudinally and makes structure also obtain firmly up and down, and the relative slippage of difficult generation.
Fig. 2-4 adopts this connector for using the internal construction schematic diagram of weldering nail interconnection system connector, and is simple in structure, also can play the effect of connector, and be not easy to take place relative slippage.
Fig. 3-1 is for adopting the case beam longitudinal profile schematic diagram of floor cellular type connector, the multiple compound mode of a plurality of case beams, innerly between the adjacent case beam can adopt identical connector also can adopt different connectors, Fig. 3-2 for adopt the truss-like connector case beam longitudinal profile schematic diagram.
Adopt as above a kind of steel case superposed beam (plate) steel box plate connector of technical scheme, has following beneficial effect: because the connector construction easily, install simple and conveniently, make that whole box-beam structure is more stable, be subjected to after ectocine and the corresponding extruding force (load) more stable; Safety and construction easily.
And, if adopt as above technical scheme in the steel box plate 1, then its inner prestressing force can useful effect in body structure, make that the whole box body structure is more firm.
