Description
Technical Field
The utility model relates to an electric power infrastructure field specifically is an extended rag bolt fixing device for iron tower basis.
Background
In the engineering construction process of the 110kV overhead transmission line, due to interference of a plurality of external factors, the situation that half of the engineering construction is suspended frequently occurs, the operation is blocked after the foundation construction is finished, and the iron tower foundation concrete is found to be seriously corroded by exposed foundation bolts when the iron tower is prepared to be assembled after 2 years.
Disclosure of Invention
The utility model aims at providing an extend rag bolt fixing device for iron tower basis in order to solve because the influence of shutting down leads to the problem of pre-buried rag bolt corrosion.
The utility model discloses a concrete scheme is: the utility model provides an extend formula rag bolt fixing device for iron tower basis, including the foundatin plate, the four corners department of foundatin plate respectively is equipped with a rag bolt, the rag bolt lower extreme stretches into in the precast concrete, the outside limit welding of foundatin plate has two L shape expansion boards, the interior limit of L shape expansion board is laminated with two limits that the foundatin plate is adjacent, be equipped with two seams between two L shape expansion boards on the diagonal that lies in the foundatin plate, the seam crossing welding of two L shape expansion boards, be equipped with a plurality of through-hole on every L shape expansion board, an stock is equipped with in every through-hole, the stock bottom inserts in the precast concrete, the stock top is equipped with external screw thread and protrusion L shape expansion board, lock nut is equipped with at the stock top.
Be equipped with two vertical backup pads of arranging on the foundatin plate, two backup pads are mutually perpendicular, L shape extend be equipped with on the board with backup pad outside limit welded connecting plate.
Four outside limits of two backup pads have welded a connecting plate respectively, board welding is extended with the L shape that corresponds in each connecting plate bottom.
Stock bottom is equipped with outside open claw rib.
The working principle of the utility model is as follows: after the embedded foundation bolt is corroded due to long-time shutdown, the two L-shaped expansion plates are welded to the periphery of the foundation plate on site during rework, then the joint of the two L-shaped expansion plates are welded together, then the connecting plate is welded with the supporting plate on the foundation plate, deep holes are drilled in the corresponding through holes of the L-shaped expansion plates, and finally the anchor rod and the locking nut are installed for fixing.
The utility model has the advantages of it is following: the expansion plate is additionally arranged to be connected with the foundation plate, the anchor rod is additionally arranged to replace an original foundation bolt, the problem that the original foundation bolt is corroded is solved, the iron tower is convenient to assemble during reworking, and the treatment efficiency is improved.
