Assembly type buckling restrained brace capable of visually inspecting segmented restraint

Abstract

The invention discloses an assembly type buckling restrained brace capable of visually inspecting segmented restraint. The assembly type buckling restrained brace capable of visually inspecting the segmented restraint comprises a supporting inner core, cushion blocks and limiting cushion blocks, wherein first end peripheral restraint devices, middle peripheral restraint devices and second end peripheral restraint devices are detachably connected in the length direction of the supporting inner core, and the first end peripheral restraint devices, the middle peripheral restraint devices and thesecond end peripheral restraint devices are relatively distributed on two surfaces of the supporting inner core and are detachably connected with the supporting inner core; the cushion blocks are arranged between the two groups of first end peripheral restraint devices and the two groups of second end peripheral restraint devices in a filling mode and are detachably connected with the first end peripheral restraint devices and the second end peripheral restraint devices; and the limiting cushion blocks are arranged between the two groups of middle peripheral restraint devices in a filling modeand are detachably connected with the middle peripheral restraint devices. According to the assembly type buckling restrained brace capable of visually inspecting the segmented restraint, the damagedparts can be replaced in segments to avoid waste of materials; and only the positions of the cushion blocks and the limiting cushion blocks on the two side surfaces of the supporting inner core are blocked, and the rest of the positions are completely visible, and convenience is provided for monitoring the deformation and damage of the supporting inner core of the buckling restrained brace.

Description

technical field [0001] The invention relates to the technical field of shock absorption of civil engineering structures, and more specifically relates to an assembled buckling-constrained support with visually inspectable segmental constraints. Background technique [0002] Buckling-restrained bracing is composed of bracing inner core and peripheral restraining device. The bracing inner core mainly bears the axial force and uses its plastic deformation to consume seismic energy. Lateral buckling, there is a certain gap between the inner core and the peripheral restraint device to ensure that the supporting inner core will not be blocked due to lateral expansion when it is compressed. [0003] At present, the peripheral restraint devices of prefabricated buckling-restrained braces can be divided into three categories according to the materials and combinations of the restraint devices: concrete prefabricated peripheral restraint units, steel pipe concrete composite prefabrica...

AI Technical Summary

Problems solved by technology

However, in post-earthquake repairs, it is necessary to disassemble all the peripheral restraint devices of the fabricated buckling-restrained brace before visually inspecting the buckling-restrained brace, and it is impossible to quickly observe the damage of the buckling-restrained brace

[0004] In addition, even if local damage to the peripheral restraint device is found after the earthquake, the entire peripheral restraint device needs to be replaced, resulting in serious waste
