Non-welding buckling restraining support with inspection windows

Abstract

The invention provides a non-welding buckling restraining support with inspection windows. The non-welding buckling restraining support with the inspection windows comprises an inner core steel core and a peripheric restraining unit. The inner core steel core is a Chinese character Yi shaped steel plate, the peripheric restraining unit comprises an energy dissipation section, the energy dissipation section is in axial direction to transition sections on two ends and mounting sections on the outer sides of the transition sections, the energy dissipation section is an GFRP (glass fiber reinforced polymer) rectangular tube with ribs, the GFRP rectangular tube is filled with contoured foam when contoured, and a GFRP rib in the tube is arranged vertical to the inner core steel core. A plurality of inspection windows are arranged, vertical to the inner core steel core, on an axis of the energy dissipation section , the transition sections are GFRP expansion joints, the mounting sections are GFRP ribbed stiffeners vertical to the inner core steel core and forming a cross shape with the inner core steel core, and polyurethane foam is wrapped by glass fiber cloth to be injected resin in vacuum to solidify to form the whole supporting member in integrity. The non-welding buckling restraining support with the inspection windows is reasonable in structure, light in self weight, anti-corrosion, and free of maintenance and welding, can monitor deformation of inner core in real time via the inspection windows to judge whether having buckling or not so as to have anticipation judgment on supporting conditions.

Description

technical field [0001] The invention relates to a constrained support of a building structure, in particular to a buckling constrained support without welding and with an observation window. Background technique [0002] The existing buckling-constrained bracing can better improve the dynamic characteristics of the structure and improve its anti-vibration or anti-seismic performance. However, the existing buckling-constrained braces mainly have the following shortcomings: [0003] (1) Self-mass of hybrid buckling-constrained bracing members. When used in a high-rise steel tower structure, when the longitudinal dimension of the support is large, there may be initial deflection and deformation of the self-significant support member during installation and use, which will have an adverse effect on the support performance. At the same time, the self-significant The buckling-restricted bracing members are not convenient for installation and construction. In addition, poor corr...
