摘要

The present invention relates to a street lamp pole having a three-axis (x, y, z) simultaneous pressing and fixing structure, a rotation preventing structure of a pole, a self-weight slip-type close contact fixing structure, and a high-strength support reinforcement structure. Accordingly, the technical gist of the present invention is that when assembling the connection part between the lower post and the upper post, the U-bolt having an inclined assembly angle is strongly pulled along the oblique direction based on the upper post-side locking jaw, and the divided two posts are in close contact in one direction. It is pressed together and at the same time, the vertical direction (x, y) and the lateral direction (z) are immediately fixed in close contact at once. It is formed to be press-fixed, so that strong and superior fastening force (bonding strength, structural rigidity and assembly durability) is realized, while remarkably improved work convenience and constructability (can be used interchangeably and composite use between different materials is possible), productivity and economic feasibility It is characterized in that this is guaranteed. Accordingly, in the present invention, the lower end of the connecting tube provided in the lower post (main tube) is firmly supported and fixed by a cross-shaped reinforcing support, which is supported and fixed at two points up and down together with the upper fixing plate. It is characterized by a strong bearing capacity and greatly improved bearing performance. In addition, the present invention has a gear tooth-shaped concave-convex groove formed at the lower end of the upper post (post pipe) so that when inserted into the connecting pipe of the lower post, the trough of the concave-convex groove corresponds to the circumferential rotation of the bar, which is a vehicle It is characterized in that safety problems during rotation (flow) of the holding such as distortion and inclination generated from vibration of the wind and external force of the wind can be completely solved. Accordingly, the present invention is such that a right triangular or wedge-shaped pressure pin is penetrated and coupled to one side of the connecting pipe so that when the upper post is inserted downwardly by the protruding inclined surface, a one-way sliding contact assembly is made with respect to the inner circumferential surface of the connecting pipe, but the pressure pin is The bar is easily assembled and mounted from the outside of the connector through the through slit groove, which is easy to process and easy to join, so that the operator can secure high work productivity. do.
