Non-destructive reinforcement device for angle steels of communication iron tower, and construction method thereof

Abstract

The invention provides a non-destructive reinforcement device for angle steels of a communication iron tower, and a construction method thereof. The communication iron tower comprises a plurality of tower segments, each tower segment comprises a plurality of reinforcement units, and each reinforcement unit comprises an angle steel, a plate member and a plurality of hoop members; the plate membersare arranged along the inner length direction of the angle steels; the hoop members are symmetrically arranged on the outer sides of the angle steels, clamp the plate members, and are mutually connected through bolts. According to the requirements on suspension devices of communication iron towers, gusset plates and the hoop members are connected through bolts, and to-be-suspended devices are connected to the gusset plates through bolts; or one ends of double angles are screwed to the gusset plates, arc-shaped plates are fixed at the other ends of the double angles, and arc-shaped members arescrewed to the arc-shaped plates. The non-destructive reinforcement device and the construction method thereof have the advantages that the plate members and the hoop members are fixedly connected through high-strength bolts without damaging the angle steels of the communication iron tower, and accordingly, the ultimate bearing capacity of the angle steels is improved; the non-destructive reinforcement device is simple in structure, high in stability, low in cost and easy to operate.

Description

technical field [0001] The invention belongs to the technical field of reinforcement of communication iron towers, and in particular relates to a non-destructive reinforcement device for angle steel of communication iron towers and a construction method thereof. Background technique [0002] With the advent of the 5G era and the rapid economic development of our country, the requirements for communication sites have increased, making the required wireless communication sites more and more dense, and the antennas loaded on the communication tower will be more and denser than in the 4G era. , the carrying capacity of communication towers is facing huge challenges. Under the influence of strong wind and various other factors, many existing iron towers have been unable to effectively carry the load, which is dangerous to a certain extent. In addition, considering that new iron towers will cost a lot of money, in order to save investment, the original iron towers should be increa...

Problems solved by technology

Under the influence of strong wind and various other factors, many existing iron towers have been unable to effectively carry the load, which has certain dangers. In addition, considering that new iron towers will cost a lot of money, in order to save investment, the original iron towers should be increased. utilization rate, operators and communication tower operators will further highlight the demand for tower recycling and tower reinforcement

[0003] However, at present, there are few studies on non-destructive reinforcement at home and abroad. No practical and effective reinforcement methods have been proposed for China's angle steel specifications, and they have not been actually applied to communication towers. Simple and effective reinforcement methods still need to be developed.

The traditional iron tower reinforcement method requires a lot of on-site drilling and welding work, and the basic method of reinforcement is lossy reinforcement, which not only has low efficiency and high cost, but also requires high skills of on-site operators, making construction difficult
