Cantilever structure tension reinforcing system and construction method

Abstract

The invention provides a cantilever structure tension reinforcing system and a construction method. According to the construction method of the cantilever structure tension reinforcing system, multiple V-shaped supporting structures of the tension reinforcing system are arranged in the circumferential direction of the inner ring of an original cantilever structure at intervals; a cable net assembly comprises a radial cable and an annular cable, the annular cable is arranged in the circumferential direction and connected with the bottom ends of the V-shaped supporting structures, one end of the radial cable is connected with the annular cable, and the other end of the radial cable is connected with the original cantilever structure after being tensioned in the radial direction; the newly-added cantilever structure is arranged above the elevation of the annular cable, and one end of the rigid component is connected with the newly-added cantilever structure; the monitoring device is arranged at the tail end of the radial cable and used for monitoring the stress state of the corresponding radial cable and automatically sending an early warning signal to the background system. And through the V-shaped supporting structures and the cable net assembly, reinforced maintenance of an old building is achieved. The stress state of the radial cable is monitored by additionally arranging the monitoring device, the later operation and maintenance efficiency is improved, the internal force distribution of the structure and the cable force is controlled, deformation is controlled, and cost is saved.

Description

technical field [0001] The invention belongs to the technical field of urban building maintenance and renewal, and more specifically relates to a tension reinforcement system and a construction method for a cantilevered structure. Background technique [0002] The concept of "tensegrity" is an invention of the famous American architect Fuller. The stiffness of this structure is provided by the balanced prestress between the tension and compression units. Before the prestress is applied by the family, the structure has almost no initial stiffness, and The size of the initial prestress plays a decisive role in the shape of the structure and the rigidity of the structure. The tensegrity structure is a flexible structure that can maximize the use of material properties. At present, the common tensegrity structure consists of orthogonal two-way type, self-balancing unit type and ring cable truss structure. [0003] At present, many old buildings are about to reach the design lif...

Problems solved by technology

[0004] At present, routine maintenance and preventive maintenance are used for the maintenance of large public buildings. No matter whether the building has the possibility of failure, it is necessary to waste manpower, material resources and time costs to maintain the building.
