Connecting device for double-T plate and supporting beam

Abstract

The utility model provides a double T plate and support beam connecting device, which comprises a lower support beam and an upper double T plate, N vertical anchoring steel bars are reserved in the support beam, and the vertical anchoring steel bars protrude out of the surface of the support beam and extend to the upper part of the support beam. N blind holes matched with the vertical anchoring steel bars in a one-to-one mode are formed in the bottom of a vertical rib plate of the double-T plate, the cross section of each blind hole is in a long groove shape, an exhaust port and a grouting port are formed in the depth direction of each blind hole, and the exhaust ports and the grouting ports are communicated with the outside. By means of the technology, joint pull cracks and supporting beam damage caused by deformation caused by temperature stress can be effectively avoided, the shear resistance of the joints can be effectively enhanced, the supporting effect of the double-T plate on the whole structure is achieved, deformation such as torsion and displacement of the whole structure is effectively coordinated, and the shock resistance of the whole structure is improved.
