The content of the invention
The purpose of this utility model be the problem of presence for existing shear connector there is provided a kind of easy construction, structure safety, Anti-shear concrete performance can be improved is used for steel-concrete composite beam shear connector.
The technical solution adopted in the utility model is:
A kind of open pore steel plate shear connector, including girder steel, girder steel include steel beam web plate and steel beam flange plate, the girder steel Being welded with steel beam flange plate along the bearing of trend of steel beam web plate on open pore steel plate, open pore steel plate has more than 1 Circular hole, and be arranged with a reinforcing bar in each circular hole of open pore steel plate, each reinforcing bar is in the both sides of open pore steel plate point A spring for being in nature retracted position is not socketed with, and the two ends of the spring are fixed with reinforcing bar respectively.
As further improvement of the utility model, the circular hole on the open pore steel plate is opening dorsad steel beam flange plate Opening circular hole.
As further improvement of the utility model, the spring is fixed close to one end of open pore steel plate with reinforcement welding.
As further improvement of the utility model, the length that the reinforcing bar is located at open pore steel plate both sides is isometric, and reinforcing bar Two ends extend steel beam flange plate end set;The one end of spring away from open pore steel plate is flushed with the end of reinforcing bar, and It is welded and fixed with the end of reinforcing bar.
As further improvement of the utility model, the circular hole on the open pore steel plate is more than 3.
The beneficial effects of the utility model are:The utility model is simple in construction, easy construction, the perforated panel of its split shed It is close with traditional open pore steel plate stress performance, but reinforcing bar easily can be put into open pore steel plate at the opening of steel plate, grasped Make simpler, construction is more convenient;Wherein spring can not only improve the cracking resistance of concrete near reinforcing bar, moreover it is possible to enhancing shearing The shear strength of reinforcing bar in key, so as to improve the shearing concatenation ability and intensity of combining structure.
