Communication iron tower

Abstract

The invention discloses a communication iron tower which comprises four forward spiral frameworks distributed in an axial array and four backward spiral frameworks distributed in an axial array , wherein the backward spiral frameworks are wound on the forward spiral frameworks, and fixedly connected with the forward spiral frameworks via locking pieces, so as to form a cage-shaped tower body; eight foot margin embedding parts are arranged on the lower side of the tower body; a platform mounting part is arranged on the upper side of the tower body; the foot margin embedding parts are embedded in a cement tower base; a bearing platform is mounted in the platform mounting part; a combined hand rail is mounted at the upper end of the platform mounting part. The communication iron tower has the advantages that the number of components is small; the integrity and the intensity are high; the mounting is convenient; the tower body is relatively high in tenacity and elasticity; the intensity distribution of the tower body is uniform; the capabilities of resisting side forces in all directions are the same; the stability is high; lateral stress can be dispersed; the side force impact can be buffered; the damage resisting capacity is high.

Description

technical field [0001] The invention relates to a steel structure building, in particular to a communication iron tower used in the fields of mobile communication, radio and television, and the like. Background technique [0002] Communication towers are mainly used for the transmission and launch of microwave, ultrashort wave, and wireless network signals, and are necessary infrastructure for mobile communications, radio and television, and other fields. The current communication towers are mostly angle steel towers, three-pipe towers and single-pipe towers. The three types of communication towers have different defects in the process of installation and use. [0003] Angle steel tower, the tower body is connected and assembled by different types of angle steel components. First of all, the cross-section of this type of tower is generally rectangular or triangular. Affected by its unreasonable tower structure, the distribution of tower body strength and lateral force resis...

AI Technical Summary

Problems solved by technology

First of all, the cross-section of this type of tower is generally rectangular or triangular. Affected by its unreasonable tower structure, the distribution of tower body strength and lateral force resistance is uneven, that is, this type of communication tower caters to lateral forces in different directions. (caused by typhoons, earthquakes, etc.), the resistance shown is different. In the case of a certain material cost, there is still room for improvement in its damage resistance; secondly, there are many components, and installation is more troublesome. It is difficult to guarantee, which affects its overall strength and service life, and the gap between adjacent components is prone to accumulate rainwater and rust, which also has a certain impact on the service life; Malicious destruction, but also a great security risk

[0004] The three-tube tower, compared with the angle steel tower, only has a certain improvement in strength, and has the same defects as the angle steel tower

[0005] The single-tube tower, the tower body is made of several prefabricated tower tubes connected by flanges. Compared with the angle steel tower, it has the advantages of simple structure, beautiful appearance, quick installation, and small footprint. For the type structure, its strength and safety can only be improved by increasing the pipe diameter, thickening the pipe wall, and selecting high-performance materials. Therefore, most of them are currently limited to medium and low height communication towers, otherwise the cost is too high; The wind load coefficient is slightly larger, and the wind resistance capacity needs to be improved

[0006] The overall elasticity of the current angle steel tower, three-pipe tower and single-pipe tower is poor, and the lateral load caused by typhoons and earthquakes cannot be dispersed in a timely and effective manner, and the lateral load cannot be buffered by small swings. impact, prone to breakage accidents
