Combining closely between upper flange, is conducive to improving clamping and fastening effect；During specific installation, first by the long side of rectangle clamping face
Direction is perpendicular to the plate length direction of the upper flange of joist, and now the long side of the close upper flange of rectangle clamping face is by upper flange and bottom
Plate is clamped together, and upper flange and backing plate are then clamped together by the long side of the remote upper flange of rectangle clamping face, keeps rectangle
The clamp position of clamping face, then rotates two special shaped screw bolts, tightens nut, you can tightly clamp upper flange and bottom plate solid
It is scheduled on 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, so as to realize that what is fastened the most grips effect.
3rd, due to being provided with the profile matched with torque tool head in the afterbody of shank of bolt, make torsion bolt can be on bridge floor
Operation, torque nut is also to be operated on bridge floor, all can be in bridge plate so as to be unclamped, turned to and be fastened to special shaped screw bolt
The operation that is attached and removed from during top-operation, i.e. in-site installation is carried out all on bridge floor, and constructing operation is easier, and security
It is good.
Component will not be damaged when the 4th, removing, and reusability is preferable.
