Abstract
The utility model provides a shear resisting connecting piece, which consists of a corrugated sheet steel 1, a twisted bar 2, and a hole 3 on the corrugated sheet steel. The thread pitch of the twisted bar 2 is uniform with the row pitch of the hole 3 on the corrugated sheet steel; the twisted bar 2 passes through the hole 3 on the corrugated sheet steel. The horizontal shearing force is resisted by an oblique table-flap of the corrugated steel plate 1 and a concrete pin in the hole on the corrugated steel ventral shield 1, wherein, the concrete pin passes through the twisted bar 2. The twisted bar resists the horizontal shearing force and the drawing force. The structure that the twisted bar 2 passes through the hole of the corrugated steel ventral shield avoids welding construction, the construction is convenient, and the concrete can flow into conveniently during pouring. The twisted bar passing through the hole of the corrugated sheet steel and the concrete in the hole form a connecting pin for resisting the horizontal shearing force and the drawing force.

Summary of the invention
Technical problem to be solved in the utility model provides a kind of novel embedded type shear connector, and it is made up of the corrugated sheet steel of perforate, the spiral reinforcement that passes the corrugated sheet steel hole.
The said embedded type shear connector of the utility model is made up of the some holes 3 on corrugated sheet steel 1, spiral reinforcement 2, the corrugated sheet steel, and described spiral reinforcement 2 passes the hole 3 on the corrugated sheet steel.
The pitch-row in the hole 3 on the above-mentioned embedded shear connector, the pitch of described spiral reinforcement 2 and corrugated sheet steel is consistent.
Above-mentioned shear connector can also comprise the straight reinforcing bar 7 that passes hole 3 on the corrugated sheet steel.
The said embedded shear connector of the utility model, further scheme is, connects perforate plain plate 4 on corrugated sheet steel 1, and some holes 6 are arranged on the perforate plain plate 4, links together by bolt 5 between perforate plain plate 4 and the corrugated sheet steel 1.
Said hole in the utility model can be washed into various geometries such as circle, polygon and ellipse as required, can be that same size also can be different, shape can be identical also can be different.
The utility model compared with prior art has the following advantages:
1, spiral reinforcement passes the Wavelike steel webplate hole, has avoided welding procedure, easy construction.
2, spiral reinforcement can with concrete obvolvent well together, have the effect of good opposing horizontal shear.
Concrete inflow when 3, being convenient to build.Concrete in spiral reinforcement and ostium forms connecting pin, has the performance of very strong opposing horizontal shear.
4, spiral reinforcement has played the effect of opposing pulling capacity.
5, shear connector has good fatigue durability.
