Problems solved by technology

Since the panel and the keel are connected by self-tapping screws, the performance under earthquake action (reciprocating load) is poor, the hysteresis curve is severely pinched, and the energy dissipation capacity is seriously insufficient

Embodiment approach

[0035] The production process of the prefabricated cold-formed thin-walled steel composite shock-absorbing wall:

[0036] During specific implementation, firstly, the cold-formed thin-walled C-shaped steel (8) and the cold-formed thin-walled U-shaped steel (9) are cut according to the modulus size (0.6m) of the assembled cold-formed thin-walled steel composite shock-absorbing wall. attached figure 2 Shown form, spliced ​​into I type combined vertical side column (1a) by pitch 00mm-300mm. The blanked cold-formed thin-walled U-shaped steel (9) is drilled into the turnbuckle bolt holes and processed into a U-shaped horizontal guide rail (1b). Opening a waist round hole of a suitable size in the middle part of the blanked cold-formed thin-walled C-shaped steel (8) web is processed into a C-shaped vertical center column (1c). then follow the attached figure 1 And attached Figure 4 The positions shown are pre-positioned on the factory assembly line, and then Image 6 The scre...

Abstract

The invention discloses a fabricated thin-walled cold-formed steel combined damping wall. A thin-walled cold-formed steel wall framework is a rectangular framework system formed by upper and lower U-shaped horizontal guide rails, H-shaped vertical side columns and a C-shaped vertical center column. Each energy-dissipation damping unit is a diagonal supporting system formed by a self-reset damper,a steel pull rod, a cylindrical rotating clamp and a retaining bolt. The two systems are connected into a whole through anti-pulling connection parts and operate jointly. A wall panel and the thin-walled cold-formed steel wall framework are connected through tapping screws, and the thin-walled cold-formed steel wall framework, the energy-dissipation damping units, a rock wool thermal insulating layer and the wall panel form the fabricated thin-walled cold-formed steel combined damping wall jointly. The fabricated thin-walled cold-formed steel combined damping wall integrates stress, damping, thermal insulation and fire prevention and is simple in structure, convenient to construct, high in performance, practicality and economy and suitable for industrial production and has a promising market prospect.

Description

technical field [0001] The invention relates to an assembled cold-formed thin-walled steel composite shock-absorbing wall, which belongs to the technical field of structural engineering, in particular to a composite wall with multiple functions of structure, heat preservation, fire prevention and vibration control and its production Manufacturing method. Background technique [0002] Due to the strengthening of human environmental protection awareness and the shortage of forest resources, more and more countries around the world are using cold-formed thin-walled steel structures as load-bearing systems for residential buildings. 1. The affinity of indoor living space to people is basically the same as that of traditional houses, and the comprehensive economic indicators are obviously better than concrete structures, ordinary steel structures and wood structures. At present, many steel structure companies and scientific research institutions at home and abroad are conducting...
