Communication guyed tower and assembling method thereof

Abstract

The invention relates to a communication guyed tower and an assembling method thereof. The communication guyed tower comprises a triangular tower body, and the three corner parts of the tower body are each provided with a guy wire set, the each stay wire set comprises four upper pulleys, two lower pulleys, a stay wire base and a stay wire, the four upper pulleys are arranged at the corner parts of the tower body at equal intervals in the height direction, the two lower pulleys are arranged on the stay wire base in the front-back direction, the stay wire sequentially bypasses the lower pulley located at the rear part, the two upper pulleys located at the lower part, the lower pulley located at the front part and the two upper pulleys located at the upper part, and the two ends of the stay wire are connected in a closed loop manner. According to the communication guyed tower and assembling method thereof, the purpose of improving the wind resistance of the guyed tower can be achieved.

Description

technical field [0001] The invention relates to a communication guy tower, which belongs to the technical field of communication equipment. Background technique [0002] In the communication industry, guyed towers are widely used as carriers for communication antenna elevation. The guyed tower generally adopts a truss-type tower body with a triangular cross-section. The tower body itself only bears vertical force and bending moment, and the horizontal direction relies on prestressed guy wires to maintain stability. When the guyed tower encounters strong wind, the tower body will bear a lot of force in the horizontal direction, which is prone to accidents such as disconnection of the guyed wire and collapse of the tower body. Therefore, the design of the guyed tower needs to focus on its wind resistance. The guyed towers in the prior art all adopt three layers of guyed wires, and each layer of guyed wires is independently connected to the tower body. Under strong wind condi...

AI Technical Summary

Problems solved by technology

Under strong wind conditions, the displacement of the upper part of the tower body is the largest. Correspondingly, in order to resist this displacement, the tensile stress is concentrated on the uppermost guy wires, which easily leads to the disconnection of the upper guy wires. After the upper layer guy wires are disconnected, the lower layer guy wires are stressed. Sudden increase, it is also easy to disconnect, and eventually the tower body collapses; in addition, when the stay wire of the structure is stressed, the stress is concentrated on a certain fixed position of the stay wire, and this position is prone to fatigue failure and fracture due to long-term stress, which is specifically reflected in Both ends of the guy wire are prone to broken strands; in addition, in the document "Analysis of the Collapse Accident of a Communication Guy Tower" (Zhang Bo. Special Structure, Vol. When it comes to complex and numerous pull wire fittings, it will reduce the reliability of the structural safety, and the pull wire is prone to loose strands at the peach chuck

The above problems will lead to insufficient wind resistance of the guyed tower
