Description
Technical Field
The utility model relates to the field of fasteners, in particular to a hook bolt.
Background
The bridge deck system of the railway steel truss girder bridge usually adopts an open bridge deck system, namely, sleepers are directly placed on longitudinal beams of steel girders, upper flanges of wood guards, the sleepers and the steel girders are fixed through hook bolts, and the conventional hook bolts adopt L-shaped structures with enlarged base angles. The conventional hook bolt is suitable for most of conditions, but a vertical stiffening rib is usually arranged at intervals for a longitudinal beam of a steel beam, if the position of the stiffening rib is just at the position of the hook bolt, conflict can be generated between the stiffening rib and the hook bolt, the conventional hook bolt cannot be installed in place to play a role, the conventional hook bolt is usually used for partially cutting off the screw part of the hook bolt to adapt to the position requirement, or the hook bolt is rotated by a certain angle to enable the top surface of a bottom corner of a part of the hook bolt to be in contact with the steel beam, so that the hook bolt is influenced to play a role. If the top surface of the longitudinal beam is provided with the fish-shaped plate, the fish-shaped plate is connected and fixed with the top surface of the steel beam through the bolt, and the bolt can obstruct the fixation of the traditional hook bolt. In addition, some sidewalk brackets of steel beam bridges are connected out through steel beam rib plates, and hook bolts cannot be directly transmitted in, so that the installation or replacement construction of the hook bolts is influenced. The conventional hook bolt is complex to process, and can only be fixed after penetrating the bolt from bottom to top in use, so that the operation is difficult.
A new split sleeper bolt is needed.
