Abstract
The utility model relates to a steel - mix combination to construct with anti -corrosion performance is equipped with steel - mix combination to construct with anti -corrosion performance at concrete slab or concrete longeron with the gooseneck joint portion, steel - mix to combine the structure connecing shear force tack welding on the corrosion resistant plate of faying face steel sheet face, concreting formed again structure, the faying face steel sheet is the faying face steel sheet that comprises the corrosion resistant plate of substrate steel sheet on and. The construction method is the precast concrete longeron, make the preparation gooseneck with the clad steel plate, shear force tack welding is on the corrosion resistant plate face, and the hoist and mount of concrete longeron are taken one's place, concreting on corrosion resistant plate forms bridge steel - muddy structure that combines. Adopt the utility model discloses steel - mix the problem that the faying face corrodes because of the infiltration of concrete slab fracture can effectively be avoided to shear force nail, steel construction and concrete slab or the common atress of concrete longeron, and the durability is good, and the atress is reliable, construction convenience, easy operation, practices thrift construction cost, and steel - concrete faying face later stage need not maintained.
Description
Technical field
The utility model relates to a kind of bridge steel-mixed combined structure with Corrosion Protection.
Background technology
Steel concrete combining structure is linked together by shearing bonding surface, and have good technical and economic performance, in engineering structures, Application comparison is extensive.Build jointly in the design of double deck freely-supported steel truss girder bridge at a public iron, for reducing investment outlay, highway bridge and railway deck all adopt concrete structure.Wherein, driving longeron adopts the reinforced concrete beam of gooseneck supporting, and prefabricate, in the cast-in-place seam in gooseneck top.Railway deck adopts concrete longeron tool to have the following advantages: one is that railways train operation noise is little, reduces to disturb residents; Two is be easy to safeguard, without the need to application; Three is that steel using amount is little generally for employing combining structure, good economy performance.
But railway deck is arranged in structure bottom.Freely-supported steel truss girder lower chord tension, longitudinal beam structure is in operation stage also tension, and binding site concrete can produce microcrack.For traditional bridge steel-mixed integrated structure, the phenomenon that bonding surface occurs because of concrete slab crack and water leakage to corrode is more common, its later stage again cannot maintenance, and the generation of corrosion can reduce the cementation between steel-concrete, affects bearing capacity and the durability of steel work.
Summary of the invention
The purpose of this utility model is for above-mentioned endurance issues, provides a kind of and significantly can improve steel-mixed binding site steel work durability, simple structure, easy construction, the non-maintaining bridge steel with Corrosion Protection-mixed combined structure.
The purpose of this utility model is achieved through the following technical solutions, and has the bridge steel of Corrosion Protection-mixed combined structure, is provided with the steel with Corrosion Protection-mix combined structure in concrete slab or concrete longeron and gooseneck joint portion; Described steel-mixed combined structure is welded on the corrosion resistant plate face of bonding surface steel plate WELDING STUDS, then the structure that concreting is formed; Described bonding surface steel plate be by substrate steel sheet and on the bonding surface steel plate that forms of corrosion resistant plate.
The steel plate be combined with concrete slab is adopted composite steel plate by the utility model, by the WELDING STUDS being welded on corrosion resistant plate surface, steel work and concrete slab or concrete longeron are connect, form jointly stressed structural element, effectively can avoid the problem that steel in structure operation process-mixed bonding surface corrodes because of concrete slab crack and water leakage, successfully enhance steel-mixed integrated structure durability, stressed reliable, easy construction, simple to operate, save construction cost, the steel-concrete bonding surface later stage does not need to safeguard.
Though the utility model primary construction cost slightly increases, the remarkable in economical benefits of life cycle management.The utility model can be widely used in steel-concrete combined structure, is particularly useful for the situation of binding site concrete cracking.

Fig. 1 is the utility model structural representation,
Fig. 2 is the close-up schematic view of oval part in Fig. 1,
Fig. 3 is WELDING STUDS welding close-up schematic view.
Detailed description of the invention
Elaborate the utility model with reference to the accompanying drawings.
With reference to Fig. 1,2,3, the utility model is provided with the steel-mixed combined structure 3 with Corrosion Protection at concrete slab or concrete longeron 1 with gooseneck 2 joint portion, described steel-mixed combined structure 3 is welded on the corrosion resistant plate face of bonding surface steel plate by WELDING STUDS 4, concreting 5 again, the structure formed; Described bonding surface steel plate be by substrate steel sheet 7 and on the bonding surface steel plate that forms of corrosion resistant plate 6.
The crossbeam that gooseneck 2 makes for composite steel plate.The utility model considers the corrosion resistance of composite steel plate and the welding performance of WELDING STUDS, to determine the corrosion resistant plate thickness of bonding surface steel plate, and the thick 2mm of corrosion resistant plate 6.
Construction method of the present utility model, concrete steps are as follows:
1) precast concrete longeron 1;
2) composite steel plate is adopted to make gooseneck 2 as top board;
3) WELDING STUDS 4 is welded on the bonding surface steel plate be made up of corrosion resistant plate 6, substrate steel sheet 7, i.e. on the corrosion resistant plate 6 of gooseneck 2 top board (see Fig. 3);
4) by concrete longeron 1 hoisted in position;
5) concreting 5 on corrosion resistant plate 6, forms bridge steel-mixed combined structure 3.
Compared with the utility model and traditional steel-mixed combined structure innovation have employed stainless compound steel plate, do not increase any structure structure, structure is simple, easy construction, substantially increases the durability of steel-mixed bonding surface.
