Pole/tower with multiple layers of pole members in nested arrangement

Abstract

The invention provides a pole / tower with multiple layers of pole members in nested arrangement. The pole / tower comprises N cylindrical main poles and M sleeve groups, wherein each of the sleeve groups comprises at least one tubular sleeve; the main poles are connected end to end to form an upright long main pole, the inner walls of the sleeves in No.1 sleeve group are attached to the outer walls of the main poles and fixedly nested outside the long main pole, and at least one butt joint part of two butt joint main poles is covered on any sleeve in the No.1 sleeve group; similarly, the inner walls of the sleeves in an outer-layer sleeve group are attached to the outer walls of the sleeves in an inner-layer sleeve group and fixedly nested outside an inner-layer long sleeve; and as a result, totally M layers of long sleeves respectively butted by multiple free sleeves are nested outside the upright long main pole. The long sleeve of each layer is nested outside the long main pole in a laminating manner to effectively disperse the stress on the butt joint parts, so that the pole / tower can meet the requirement for flexibility and reduce the stress on the butt joint parts of the pole members to the extent that the pole / tower is safe.

Description

technical field [0001] The invention relates to a vertical tower assembled by multi-segment rods, in particular to a multi-segment rod assembled into a tower suitable for carrying equipment and constructing a transmission and distribution network. Background technique [0002] In order to carry special equipment at a certain height outdoors, the existing technology uses pole towers as the carrying tools of the special equipment, such as wireless communication base station towers equipped with wireless base stations or wireless relay equipment, used to support large billboards, large publicity boards and road sign towers; in addition, the construction of transmission and distribution networks also requires towers to carry transmission lines. The pole tower is usually a single pole structure, which brings troubles to transportation due to the long pole tower, and also requires large-scale machinery to cooperate with hoisting during the installation process; especially in some ...

AI Technical Summary

Problems solved by technology

[0003] The tower not only bears the gravity of the special equipment, but also bears the lateral thrust caused by the wind and rain in the natural environment; for the tower constructed of multi-section rods, the lateral thrust will The connecting parts between the rods cause stress concentration, and the stress existing between the butt rods cannot be completely eliminated

In the prior art, a variety of connector schemes arranged at both ends of the rods have been designed, in order to enable the tower to overcome the stress between the rods under the condition of meeting the deflection index; however, either the connectors The structure is relatively complex and not suitable for application, or the connector cannot overcome the stress concentration and cannot meet the expected technical indicators

In particular, when the two butt-connected rods are not made of the same material, for example, when a fiber-reinforced plastic rod made of extrusion, drawing, or wet wrapping is connected to a metal rod, it is very difficult to It is difficult to make the pole tower meet the deflection index and overcome the stress concentration problem at the joint between the two poles
