Problems solved by technology

[0005] However, the above-mentioned energy-consuming structural system has great deficiencies. Firstly, the energy-consuming devices are installed in the structure, and most of them are non-standardized products. External, exposed to air, susceptible to oxidative corrosion, difficult to maintain and replace

Embodiment Construction

[0036] The invention will be described in further detail below in conjunction with the accompanying drawings.

[0037] A light steel damping composite wallboard, such as figure 1 , 11 , 12, 13, the composite wall panel includes a steel frame 3, a damping device 2 and an outer cladding 1.

[0038] The shaped steel frame 3 is welded by shaped steel, and the rib beams and rib columns in the frame form several grid cavities.

[0039] The damping device 2 is filled in the grid cavity formed by the rib beam and the rib column, and it is connected with the steel rib beam or the rib column as a whole by welding or bolting.

[0040] The profiled steel frame 3 containing the damper 2 is placed in the template, and the outer cladding 1 is poured with the profiled steel grid as the keel to form a light steel damping type composite wall panel.

[0041] The damping device 2 includes a sprag bending mild steel damper, a bending mild steel damper or a steel plate damper.

[0042] The obli...

Abstract

The invention provides a light-steel damping composite wallboard, belonging to the anti-seismic and damping field of a building structure. The composite wallboard comprises a profile steel frame (3), a damping device (2) and an external cladding (1), wherein, the profile steel frame is formed by welding profile steel, and ribbed beams and ribbed columns in the frame form a plurality of grid cavities; the damping device is filled into the grid cavities so that the grid cavities are integrated with the ribbed beam or the ribbed column of the profile steel; and grids of the profile steel are taken as a keel for pouring the external cladding to form the light-steel damping composite wallboard. In the invention, by additionally arranging the damping device, the capability of the wallboard for consuming seismic energy can be improved; and the external cladding, the damping device and the profile steel frame of the wallboard can play roles by stages under action of small earthquakes, medium earthquakes and major earthquakes, so the wallboard has a plurality of anti-seismic defense lines. The grid styles of the profile steel and the layout of the damping device in the wallboard can be flexibly arranged and freely combined according to different design objectives so that the wallboard can reach different performance levels according to the intention of a designer, thus really realizing individualized structural design; and the wallboard is particularly applicable to load-bearing wall members in an anti-seismic structural system.

Description

technical field [0001] The invention relates to an energy-consuming composite wallboard, which belongs to the field of anti-seismic and shock-absorbing building structures. In particular, this composite wall panel is especially suitable for load-bearing wall elements in earthquake-resistant structural systems. Background technique [0002] Earthquake is a sudden natural disaster that endangers the safety of people's lives and property, and is extremely destructive and harmful. Especially in densely populated and industrially developed cities and regions, the losses are even more severe. With the acceleration of China's urbanization process, higher and higher requirements are placed on the seismic performance of structures. The traditional structural system mainly relies on the hysteretic energy dissipation caused by the plastic deformation of structural materials to dissipate energy, because the hysteretic energy consumption is the damage energy of the structure, and the re...
