Hold together, the long side away from upper flange of rectangle clamping face is then clamped together upper flange and backing plate, keep rectangle clamping
The clamp position in face, then rotates two special shaped screw bolts, tightens nut, you can be tightly clamped to upper flange and base plate
Together.
2nd, the consistency of thickness of the thickness of backing plate and upper flange, being provided with for the backing plate is beneficial to keep clamping face and upper flange
Bottom surface flush such that it is able to realization fasten the most grip effect.
3rd, it is polygonal endoporus because the afterbody in shank of bolt is provided with cross section corresponding with fastening tool shape, can
To adapt to the insertion of various fastening tools, all can grasp above bridge plate so as to being unclamped to special shaped screw bolt, be turned to and being fastened
The operation that is attached and removed from when work, i.e. in-site installation is carried out all on bridge floor, and constructing operation is easier, and safety is good.
Component will not be damaged when the 4th, removing, and reusability is preferable.
