Cross perforate, be fixed on by nut on the flange plate of section steel beam.That is, nut is set in the end of the second threaded shank.
In this embodiment, the length of second threaded shank not less than the flange plate of section steel beam thickness and nut thickness it
With the end thread of the nut and screw rod is fixed.In this embodiment, the inner surface of the perforate can be provided with spiral shell
Line, screw thread can also be not provided with.
The utility model also provides a kind of building element of anti-load, and it includes above-mentioned shear connector and armored concrete
Plate, the first threaded shank are arranged on the inside of the armoured concrete slab.The building element can be manufactured by the following method：In type
The side of the bolt protrusion of the flange plate of girder steel sets steel bar stress, then casting concrete, so as to form armored concrete
Plate.Now in the inside of armoured concrete slab, section steel beam and armoured concrete slab are combined together the first screw parts by it.This
In utility model, the thickness of described armoured concrete slab is more than the length of the first threaded shank.
Shear connector of the present utility model employs bolt and flange plate with specific structure, effectively overcomes tradition
Weld stud connect band the defects of coming and deficiency, installation is simple, quickness and high efficiency, and cost is low.Meanwhile shearing resistance of the present utility model
Connector realizes effective rigidity by simple method and connected, and shear-carrying capacity and deformability and anti-" starting power " show
Enhancing is write, ensure that section steel beam and armoured concrete slab preferably cooperation.In addition, welding procedure is eliminated, so as to reduce
Whole construction costs.
