Abstract

The utility model discloses a steel-concrete combined beam PBL and welded steel bar shear connector structure. A perforated ribbed plate 3 and a semielliptical welded steel bar 4 are welded at the upper end of a steel beam flange plate 2; and a penetrating steel bar 5 is directly put into two symmetrical open holes 6 of the ribbed plate and penetrates through a semicircle of the welded steel bar 4.

Description

Steel-concrete composite beam PBL+ welded reinforcement shear connector structure
Technical field
The utility model relates to a kind of novel steel-concrete combination beam PBL+ welded reinforcement shear connector structure, is used for connecting the girder steel and the concrete bridge deck of combining structure bridge, belongs to the bridge construction field.
Background technology
Steel-concrete composite beam combines steel, two kinds of different materials of concrete rightly, has improved the service efficiency of stability of structure, intensity and material.Steel-concrete composite beam is a kind of important horizontal load-bearing combined member; It is combined into whole bearing load to girder steel and concrete flange plate through shear connector, thereby makes compound beam can give full play to steel tensile property and the good advantage of concrete compressive property.The PBL shear connector is a heavy connection that the armored concrete slab on top and bottom girder steel is combined into whole cooperative combination flexural member.
Steel-concrete composite beam can make full use of advantages such as properties of materials, shock resistance is good, cost is low with it, obtains application more and more widely in Structural Engineering fields such as industrial, civilian and bridge constructions.The design of connector is a key link, and it is directly connected to the supporting capacity of whole compound beam.Difficult point wherein is the vertical equity shearing that utilizes rational connector to control effectively to take place between steel and the concrete material.The utility model proposes a kind of steel-concrete composite beam PBL+ welded reinforcement shear connector structure, has characteristics safe and reliable, easy construction.
The utility model content
The technical problem that the utility model will solve is the PBL+ welded reinforcement connector structure that newly makes new advances, and makes more safe and reliable, the easy construction that is connected between two kinds of materials of steel and concrete.
The utility model is realized through following technical scheme: steel-concrete composite beam PBL+ welded reinforcement shear connector structure, comprise steel floor, floor perforate in the composition, and run through reinforcing bar, welded reinforcement.Welded reinforcement is the half elliptic reinforcing bar, is arranged in to run through reinforcing bar two ends and floor centre position, welds with the girder steel frange plate.Run through reinforcing bar and cross welding machine reinforcing bar and floor perforate.
The technological progress that the utility model is obtained is: in the structure, wrap up the inner concrete piece and laterally run through steel with welded reinforcement in the floor perforate after the moulding
Muscle forms the steel concrete shear-pin together.Reinforced concrete shear-pin opposing horizontal shear.Steel concrete in the while semiellipse welded reinforcement
Pin can also be resisted pulling capacity upwards.This combining structure shear connector co-operation is safe and reliable, easy construction.
