Embodiment Construction

[0021] Attached below Figure 1-Figure 8 The present invention is further described.

[0022] A schematic diagram of the structure and components of a buckling-constrained support with embedded steel bars and outer-wrapped fiber tubes is shown in Figure 1-Figure 8 shown. The length of the smooth round steel bar 1 is determined according to the support arrangement and the storey height, and the diameter and number of a single smooth round steel bar 1 are determined according to the limit value of the interstory displacement angle, and then the length and cross-sectional size of the constrained fiber tube 4 are determined. Multiple light round steel bars 1 are straightened and aligned at both ends. According to needs, the cross-section is combined into a circle or a rectangle. One end is mechanically pierced. The piers need to be polished. The section size of the piers after processing should be larger than the centroid of the end plate 6. The cross-sectional size of the turn...

Abstract

A buckling-constrained support with embedded steel bars and outer-wrapped fiber tubes belongs to a new type of energy-dissipating shock-absorbing component, which can be applied to structural shock absorption and engineering reinforcement. In the present invention, a plurality of light round steel bars are straightened, aligned at both ends, combined into a certain cross-sectional shape, fiber cloth is wound around the end of the combined steel bar, and the outer surface of the combined steel bar between the fiber cloths is coated with silica gel material, and after the silica gel material is dried, Penetrate the constraining fiber tube, put the end reinforcement tube on the constraining fiber tube, and fix the two ends of the composite steel bar on the two end plates. Among them, at one end of the support, the constrained fiber tube is bonded to the end reinforcing tube through structural glue; at both ends of the support, two end reinforcing tubes are welded to the two end plates respectively. A buckling-constrained support with embedded steel bars and outer-wrapped fiber tubes has the advantages of strong energy dissipation, small cross-sectional size, light weight, flexible cross-sectional form, simple structure, convenient processing, and less waste, and has a wide range of applications, which can effectively solve the current structural problems There are many problems in shock absorption and engineering reinforcement.

Description

technical field [0001] The invention is a buckling constrained support, in particular to a buckling constrained support embedded with steel bars and wrapped with fiber tubes and a manufacturing method thereof. Background technique [0002] Buckling-restrained braces can improve the buckling instability of ordinary braced members when they are under compression. In the frame support system composed of buckling-restrained braces and frames, buckling-restrained braces bear most of the horizontal load. Absorbing and dissipating external energy, thereby realizing structural energy dissipation and protecting the main structure, can significantly improve the ductility and energy dissipation and shock absorption behavior of the structural system. However, the core material of the traditional buckling-constrained bracing is steel or steel pipe, and the outer restraint mechanism is steel pipe or concrete filled steel pipe. Therefore, the section moment of inertia of the core material...
