Two constraint reinforcing bars, mainly by providing shear resistance through reinforcing bar.Compared to edge of a wing type connection type, embedded type connection type exists
There is deficiencies for durability and maintenance repairing aspect.
Summary of the invention
The present invention provides a kind of shear connector precisely in order to avoid above-mentioned existing deficiencies in the technology.
The present invention adopts the following technical scheme that a kind of shear connector, Wavelike steel webplate are upright in order to solve the technical problem
Plate structure, overlooking section is in ripple type, and at the top of the Wavelike steel webplate or bottom is contour sets each web through hole, each steel pipe
It is each passed through each web through hole setting, and each steel pipe is parallel to each other；The constraint reinforcing bar of two long tubular structures distinguishes position
In the Wavelike steel webplate two sides, the constraint reinforcing bar sequentially passes through each steel pipe setting.
Further, the Wavelike steel webplate overlook section in multiple congruences isosceles trapezoid pass through "-" type plate according to
The structure of secondary connection, the position that the web through hole setting correspond on each crest line of each plate face intersection correspond to top or bottom
Portion sets each strain gauge.
Further, when each web through hole is set to the Wavelike steel webplate bottom, it is additionally provided with flange plate, it is described
Flange plate is located above each web through hole, orthogonal to be welded in the Wavelike steel webplate two sides.
Further, two constraint parallel reinforced steel bar settings, and it is orthogonal with each steel pipe.
Further, the steel pipe be it is internal in can grouting pipe structure threaded steel pipe.
Further, the constraint reinforcing bar is spiral.
Further, two constraint reinforcing bars extend through each steel pipe and connect with each steel pipe spot welding.
The present invention provides a kind of shear connectors, have the advantages that
1, using the connection type of embedded type, in such a way that steel pipe passes through Wavelike steel webplate, constraint reinforcing bar passes through steel pipe
It is attached, avoids welding procedure, without the concern for solder joint fatigue problem, there is good fatigue durability；
2, the crest line position of Wavelike steel webplate sets strain gauge, convenient for the stress monitoring in Cheng Qiaohou use process；
3, steel pipe and constraint reinforcing bar are respectively threaded steel pipe and spiral, increase frictional force, improve horizontal shear
And binding effect；
4, when connecting with concrete floor, the flange plate being welded on Wavelike steel webplate can cover concrete floor, rise anti-
Water effect, improves integrally-built waterproofness；
5, steel pipe be tubular structure, inside can slip casting, the contact area of concrete and shear connector is increased, to make
Concrete connect even closer with connector, improves the shear resistance of connector.
