Split mounting type angle steel three-way wire drawing tower

Abstract

The invention provides a split mounting type angle steel three-way wire drawing tower. The wire drawing tower comprises a grounding base arranged on the ground, wherein a tower base and a tower bottomsection are arranged on the grounding base in sequence, the tower bottom section is provided with a layer of ordinary section, a layer of wire drawing section, two layers of ordinary section, a layerof wire drawing section, two layers of ordinary section and a layer of wire drawing section in sequence. The split mounting type angle steel three-way wire drawing tower has the advantages that a main material of single components is 90-degree standard angle steel, processing of blanking and punching is fast, and the construction period is short; the deformation of hot dipping zinc of the singlecomponents is small, and no correction is needed; a dip galvanized layer is intact, and no partial repairing of a zinc layer is needed; the size of the single components is small, the occupied space is small, the package and installation are convenient, the transport cost is low, the split mounting type angle steel three-way wire drawing tower is suitable for long-distance transportation and secondary handling; the strength of the split mounting type angle steel three-way wire drawing tower is equivalent to that of a welding tower.

Description

Technical field [0001] The invention belongs to the field of communication antenna support structures, and particularly relates to an assembled angle steel tripartite cable tower in the field. Background technique [0002] As an important equipment for ensuring basic communications and broadcasting stations, medium and short wave antennas mostly use guyed towers as supporting structures, so guyed towers are an important part of the antenna system. In recent years, the terrain where antennas are erected has become more and more complex, and more and more antennas have been installed in remote areas such as islands, inland mountainous areas, and western regions. It has become increasingly difficult for large construction machinery and transport vehicles to enter the site. The smallest assembly unit of the existing welded round steel cable towers with side widths of 0.3m, 0.5m, 0.8m, and 1m is a tower section structure, which has many shortcomings in storage, packaging, handling, tr...

AI Technical Summary

Problems solved by technology

The minimum assembly unit of the existing welded round steel guyed towers with side widths of 0.3m, 0.5m, 0.8m, and 1m is a tower section structure, which has many shortcomings in storage, packaging, handling, transportation, installation and erection, such as heat saving of welded towers. After galvanizing, the deformation of the tower section is large, the correction is time-consuming, and the zinc layer is easily damaged; the tower section is large in size, difficult to pack, takes up a lot of space for transportation (low utilization rate of the carriage), and high transportation cost, etc.

At present, a 0.5m-side-width assembled three-party cable tower used in a certain domestic unit uses 60° angle steel as the main material, which needs to be customized or bent with standard angle steel. If the purchase quantity is small, the material cost will be high and the processing time will be long.
