In prefabricated superimposed primary-secondary beam connector described in the utility model, described flat board is parallel to secondary beam place perpendicular, described prefabricated end is provided with the first deep floor perpendicular to described flat board, and described the first deep floor is to be arranged on the first junction plate that is positioned at described prefabricated end place between described two flat boards.The first deep floor that is arranged on prefabricated end can increase contact area and the binding ability of the prefabricated end of connector and secondary beam on the one hand, can effectively resist on the other hand the topple stress of the inner concrete of secondary beam pre-erection to the prefabricated end of connector.
In prefabricated superimposed primary-secondary beam connector described in the utility model, described connecting portion place is provided with the second deep floor that is parallel to secondary beam place horizontal plane, and described the second deep floor is to be arranged on the second junction plate that is positioned at described connecting portion place between described two flat boards.The second deep floor that is arranged on connecting portion can increase the bonding strength of the superimposed part of secondary beam and connector, and in the time building primary-secondary beam overlapping layers concrete, can play the topple effect of stress of fixed connecting piece, opposing.
In prefabricated superimposed primary-secondary beam connector described in the utility model, described flat board is parallel to secondary beam place perpendicular, and described prefabricated end is provided with many perpendicular to described flat board rivet, described rivet is to be arranged on the connecting reinforcement that is positioned at described prefabricated end place between described two flat boards.The rivet that is arranged on the prefabricated end of connector can be resisted secondary beam inside to the part of the prefabricated end stress that topples, and can play connection function to two parallel flats again.
In prefabricated superimposed primary-secondary beam connector described in the utility model, described support end is provided with the support backing plate that is parallel to girder upper surface, and described support backing plate is that the backing plate that is positioned at described support end place between described two flat boards is set.The support backing plate of the prefabricated bottom of connector portion can effectively increase the contact area of connector and girder, prevent that connector support end is excessive and damage concrete to the local compressive stress of girder pre-erection steel concrete, protected the complete and structural strength of prefabricated superimposed girder; On the other hand, support backing plate and also play the effect that connects two flat boards and fixed connecting piece support end.
Prefabricated superimposed primary-secondary beam connector described in the utility model adopts steel plate to make.Because the structural strength of steel plate is high, therefore the Punching Shear of connector, anti-shear ability are strong; And the stress that steel plate itself also can successfully manage prefabricated superimposed secondary beam concentrates, avoid occurring the shear crack of prefabricated superimposed secondary beam, construction quality and security performance are protected.
