Abstract
The invention discloses a steel plate-concrete flitch plate which can improve the structure bearing ability, hardness and crack resistance, belonging to bridge element area. The process is that: welding pin cutting resistant connection on the pre-moulding steel plate, setting steel net on the upper of the pin, casting concrete to assemble into an integrated unit. The process fully displays the compression-resistant performance of the concrete. The steel plate resist to bottom plate stretch-draw force from different direction. The pin delivers the shear between the steel plate and concrete and prevents the vertical separation therebetween. The invention solves the uncontrollable concrete crack problem in the application process of the steel reinforced concrete inclined, bend bridge. The inveniton tends to satisfy the plane figure of the bridge and is suitable for burden special-shaped plate in the inclined and bend bridge with a medium and small spin and building structure.
Description
Technical field
The invention belongs to the bridge member scope, particularly can significantly improve a kind of steel plate-concrete combined board of its bearing capacity, rigidity and cracking resistance.
Background technology
Skew bridge, curved bridge occupy larger proportion in the high-grade highway bridge.When tiltedly, curved spanning footpath hour, often adopt the steel concrete slab bridge of integral cast-in-situ.The modal disease of this form of structure is the concrete floor cracking, and wherein vertically the crack of acute angle direction is the most representative partially with base plate.The crack can serious bearing capacity, rigidity and the durability that reduces structure.Multiple factor such as wide and gradient changes maximum principal tensile stress direction with bridge at the bottom of the plate of integral cast-in-situ slab bridge, therefore for its design of reinforcement, not only need to satisfy the requirement that requirement of strength also will satisfy normal stress, and in actual design and construction, be difficult to usually realize effectively.
Summary of the invention
The purpose of this invention is to provide a kind of steel plate-concrete combined board that can significantly improve structural bearing capacity, rigidity and cracking resistance.It is characterized in that: melting welding shear connector peg 5 on prefabricated profiled steel plate 1, on peg 5 tops steel mesh reinforcement 4 is set, concrete 6 is cast between two side shields 2 of steel plate 1, with peg 5, steel mesh reinforcement 4 encases and steel plate 1 is combined into one, and the surface is concordant with the top of the upper flange 3 of steel plate 1.
Described steel plate 1 is trapezoidal, parallelogram, rectangle or irregularly shaped.
Described peg 5 adopts rectangular mesh shape or quincuncial arrangement on steel plate 1.
The present invention has the following advantages with respect to prior art:
(1) overcomes steel concrete tiltedly, reinforcing bar configuration direction can't be accomplished and the corresponding to difficulty of concrete principal tensile stress direction at the bottom of the plate of bent plate bridge.Steel plate-concrete combined board all can be brought into play the tensile property of steel plate on all directions, thereby can prevent structure crack effectively, helps controlling concrete cracking, and durability of structures is also significantly improved.
(2) form of structure is reasonable, and structure height reduces, and alleviates dead load.Steel plate-concrete combined board can be given full play to the characteristics that the steel tensile property is good, the concrete compressive property is good, can effectively reduce dead load, and then has significantly improved antiseismic ability, and reduces the cost of foundation.
(3) with respect to traditional steel concrete slab bridge, adopt steel plate-concrete combined board to reduce a large amount of form work engineerings and a concrete wet trade workload and a die process, reduce the site work amount, can shorten construction period, accelerating construction progress.Traffic under the bridge cut-off in can be during construction; Quick construction, the overall economic efficiency height.
(4) industrialization degree height, environmental effect are good.Steel work partly is mainly prefabrication, and quality is easy to guarantee; Reduce concrete use amount, helped environmental protection.

Fig. 2 is the schematic perspective view of steel work part.
Fig. 3 is the schematic perspective view of steel concrete part steel mesh reinforcement.
The specific embodiment
The invention provides a kind of steel plate-concrete combined board that can significantly improve its bearing capacity, rigidity and cracking resistance.In Fig. 1, Fig. 2 and steel plate-concrete combined board structural representation shown in Figure 3, melting welding shear connector peg 5 on prefabricated profiled steel plate 1, on the top of peg 5 steel mesh reinforcement 4 is set, concrete 6 is cast between two side shields 2 of steel plate 1, with peg 5, steel mesh reinforcement 4 encases and steel plate 1 is combined into one, and the surface is concordant with the top of the upper flange 3 of steel plate 1.
Below in conjunction with accompanying drawing, the specific embodiment of the present invention is further described.
Work progress of the present invention is:
Steel plate of the present invention-concrete combined board structure is made up of steel work and back pouring concrete two parts, and the two is combined into whole co-operation by the peg shear connector of melting welding on steel plate.
(1) steel work part, steel plate 1 profile determine according to the structural plan shape, can be that trapezoidal, parallelogram, rectangle or other are irregularly shaped, and steel plate thickness is generally 8～20mm, calculates according to span of slab and determines; Do not have the upper flange part as the structure cross section, this moment, side shield 2 should occupy the total height.
(2) shear connector part, 5 melting welding of shear connector peg on steel plate 1, peg diameter 13～19mm, the height 80～150mm, spacing 200～400mm can adopt rectangular mesh shape or quincuncial arrangement; When upper flange 3 and side shield 2 width or height are big, also should melting welding shear connector peg 5.
(3) steel concrete part, the steel mesh reinforcement 6 of concrete top layer setting are used to resist local hogging moment and the moment of torsion that produces, and play the effect of control temperature and shrinkage crack simultaneously; As required, in the plate base concrete, also reinforced mesh can be set, be used to improve the shear-carrying capacity of peg; The thickness of back pouring concrete 6 is 300～600mm, as required can be in concrete reserving hole, to alleviate dead load, form steel plate-hollow concrete combination slab bridge.When not satisfying deformation requirements, the steel plate bottom should be provided with interim support during construction.
