Problems solved by technology

[0007] The technical problem to be solved by the present invention is to provide an assembled inner-folding self-resetting energy-consuming support, which solves the tension-compression asymmetry, the hysteretic curve is not full, the buckling-resistant support has residual deformation under the action of earthquake, and the shape memory can be solved. The shortcomings of alloy properties affected by temperature, the assembly of internal stacking self-resetting energy-consuming supports is proposed, with fewer types of components, simple structural forms, convenient processing, easy mass production, and assembly line processing

Embodiment Construction

[0034] In order to illustrate the present invention more clearly, the present invention will be further described below in conjunction with preferred embodiments and accompanying drawings. Similar parts in the figures are denoted by the same reference numerals. Those skilled in the art should understand that the content specifically described below is illustrative rather than restrictive, and should not limit the protection scope of the present invention.

[0035] Such as Figure 1-Figure 9 As shown, an assembled inner stacked self-resetting energy-dissipating support includes an outer tube 3, a straight rod 1 and a guide rod 2. The middle part of the guide rod 2 is provided with a hollow groove, and the outer part of the guide rod 2 The surface is provided with the first stopper 28 of the guide rod, the second stopper 29 of the guide rod, the third stopper 30 of the guide rod, the fourth stopper 31 of the guide rod and the fifth stopper 32 of the guide rod from left to right...

Abstract

The invention discloses an assembly internal folding type self-reset energy dissipation bracing which comprises an outer pipe, a linear rod and a guide rod. A hollow groove is formed in the middle of the guide rod, the linear rod is inserted into the hollow groove of the guide rod, the linear rod and the guide rod are fixedly connected through a high-strength bolt, and a friction plate is arranged between the linear rod and the guide rod. A first spring, a second spring, a third spring and a fourth spring are arranged between the adjacent check blocks on the guide rod in a sleeving mode, the guide rod is sleeved with the outer pipe, an outer pipe right end plate and an outer pipe left end plate are fixedly arranged at the two ends of the outer pipe, the left end of the linear rod penetrates out of the outer pipe left end plate, and the right end of the guide rod penetrates out of the outer pipe right end plate. A main force bearing and force transferring part of the bracing is a whole, it is avoided that due to welding, the metallographic structure and performance of steel change, and welding residual stress is generated, the stress performance is more stable, a main reset device and a friction device are clear, the structure is simple in integral construction, and machining and mounting are convenient.

Description

technical field [0001] The invention relates to the technical field of self-resetting energy-dissipating supports, in particular to an assembled inner-folding self-resetting energy-dissipating support. Background technique [0002] my country is an earthquake-prone country. The occurrence of earthquakes causes damage or even collapse of buildings, resulting in a large number of casualties and economic losses. my country's current seismic design code adopts the concept of ductility design, which consumes seismic energy through the elastic-plastic deformation of structural components, and reduces construction costs while improving the seismic capacity of structures. However, after the earthquake, the residual deformation of the components will affect the normal use of the structure, and at the same time bring high repair costs, and even the structure can only be demolished and rebuilt. In order to solve this problem, the researchers proposed to add an energy-dissipating suppo...
