Problems solved by technology

[0006] The purpose of the present invention is to solve the problem of excessive residual deformation of the structure installed with traditional buckling-resistant support members after a large or moderate earthquake, which greatly increases post-earthquake maintenance and reconstruction costs, and the existing friction-type self-resetting support members are connected by friction plates. To solve the problems of loose bolts and aging of the friction surface, which cannot dissipate the seismic energy normally, a self-resetting anti-buckling support member is proposed

specific Embodiment approach 1

[0011] Specific implementation mode one: combine figure 1 Describe this embodiment, the anti-buckling support member of this embodiment consists of a square outer sleeve 1, a square inner sleeve 2, a first end plate 5, a second end plate 6, a first convex connecting plate 10, and a second convex connecting plate. plate 11, two energy-dissipating inner core plates 3, multiple reset ribs 4, two connecting plates 7 and two pairs of angle steels 8, the first convex connecting plate 10 is arranged between the two energy-dissipating inner core plates 3 , and the upper side wall and the lower side wall of the first convex connecting plate 10 are fixedly connected to an energy-dissipating inner core plate 3, and each connecting plate 7 is arranged outside the corresponding energy-dissipating inner core plate 3 and The two are affixed; the outer pair of surfaces of the square outer casing 1 is respectively provided with a pair of angle steels 8, and one end of a pair of angle steels 8 ...

specific Embodiment approach 2

[0013] Specific implementation mode two: combination figure 1 Describe this embodiment, the gap between each energy-dissipating inner core plate 3 of this embodiment and the upper side wall and the lower side wall of the square inner casing 2 is respectively 1-2 mm, and at one end and the energy-dissipating inner core plate 3 Fixed connection, the advantage of this structure is that the square inner casing 2 acts as a restraint member for anti-buckling support to realize the energy dissipation effect of the inner core; at the same time, this structure acts as a self-resetting support for the first end plate 5 and the second end plate 6 and the effect of reset muscle 4 transmission force, reach self-reset purpose with this. Therefore, it is guaranteed that the invention realizes the double effects of anti-buckling support and self-resetting support. Other components and connections are the same as those in the first embodiment.

Abstract

The invention relates to a self reset curvature-prevention support component, which relates to a curvature-prevention support component. The invention aims at solving the problems that the existing structure for installing a traditional curvature-prevention support component generates excessive residual deformation after major earthquake or moderate earthquake, so the maintenance and rebuilding cost after the earthquake is greatly increased, and the existing friction type self reset support component can not consume the earthquake energy because of the looseness of connecting screw bolts of a friction plate and easy ageing of the friction surface. A square inner sleeve pipe, two energy consumption inner core plates and a first convex connecting plate are connected in a square inner sleeve pipe, each connecting plate is fixedly connected with a pair of angle irons, one end of each reset rib is connected with a first end plate, the other end of each reset rib is connected with a second end plate, the first convex connecting plate passes through a through hole of the first end plate to be arranged outside the first end plate, two side surfaces of a square outer sleeve pipe are respectively in contact with the first end plate and the second end plate, and the second convex connecting plate is fixedly connected in the two pairs of angle irons. The invention is used in lateral-force-resistance components in the field of building structure engineering.

Description

technical field [0001] The present invention relates to a buckling-resistant brace member. Background technique [0002] Earthquake disasters have had a great impact on people's lives, mainly due to excessive damage or collapse of building structures during earthquakes. Passive control system is one of the structural vibration control systems, and is currently considered to be the most effective and feasible method to reduce the damage of the main structure. According to different damping mechanisms, passive control devices can be divided into metal dampers, friction dampers, viscous dampers, and viscoelastic dampers. [0003] Among these control devices, the buckling-resistant bracing member (BRB) has been most widely used. This is an invented support form applied to the lateral force resistance system of multi-story buildings in recent years, and it is also an efficient energy-dissipating shock absorber (damper). The non-adhesive material or gap provided between the abo...
