Abstract
The utility model discloses a kind of steel tower column cross-arm and be connected fastener, comprise column body, and be arranged at the Connection Block of column body end, Connection Block is U-shaped bending plate, U-shaped bending plate is plugged in the fluting that column body end offers, the bottom of U-shaped bending plate is connected to the bottom of fluting, the molten iron welding that U-shaped bending plate sidewall and slotted wall are condensed after being melted by welding rod, and the sidewall of U-shaped bending plate is provided with connecting hole near opening part.The utility model adopts socket connection seat to have good torsional property, adopt the fastening rising-heat contracting-cold headspace that can well reserve because of climatic effect steel that is connected of connecting hole, junction internal stress can not be caused excessive or concentrate on a place and cause junction to be burst apart, and finally make that iron tower structure is impaired even to collapse.
Description
Technical field
The utility model relates to a kind of high-tension electricity transmission iron tower manufacturing technology field.
Background technology
It is the monolithic junction plate be plugged in column top that steel tower column top under prior art is used for being connected with cross-arm what adopt, cross-arm to be connected on monolithic junction plate any side of the dual-side being connected to monolithic junction plate (no matter be) by screw fastening can cause monolithic junction plate unbalance stress, junction plate can be caused to be out of shape for long-term unbalance stress or the junction plate stress concentration district of attachment weld place and distortion easily bursts apart, disconnects under the weather conditions of cold, cause collapse of iron tower, cause power outage or security incident.
Summary of the invention
For the deficiencies in the prior art, the utility model provides a kind of steel tower column cross-arm to be connected fastener.
To achieve these goals, the utility model solves the technical scheme that its technical problem adopts: steel tower column cross-arm is connected fastener, comprise column body, and be arranged at the Connection Block of column body end, Connection Block is U-shaped bending plate, U-shaped bending plate is plugged in the fluting that column body end offers, the bottom of U-shaped bending plate is connected to the bottom of fluting, the molten iron welding that U-shaped bending plate sidewall and slotted wall are condensed after being melted by welding rod, the sidewall of U-shaped bending plate is provided with connecting hole near opening part.
The steel tower column cross-arm that the utility model provides further is connected fastener, and the two side of its U-shaped bending plate is parallel to each other, and is provided with back-up block between in the opening part of U-shaped bending plate.
The steel tower column cross-arm that the utility model provides further is connected fastener, and its back-up block is cylinder, and cylindrical diameter is with highly equal.
The steel tower column cross-arm that the utility model provides further is connected fastener, and its U-shaped bending plate opening both sides are provided with chamfering.
The steel tower column cross-arm that the utility model provides further is connected fastener, and its column body is that steel plate bending seam forms, and the thickness of steel plate is 10mm-3mm.
The beneficial effects of the utility model: the utility model adopts socket connection seat to have good torsional property, adopt the fastening rising-heat contracting-cold headspace that can well reserve because of climatic effect steel that is connected of connecting hole, junction internal stress can not be caused excessive or concentrate on a place and cause junction to be burst apart, and finally make that iron tower structure is impaired even to collapse.
Accompanying drawing explanation
