Description

The anti-buckling support of peg type combination
Technical field
The invention belongs to the aseismic control technology of building structure field, relate to anti-buckling the supports Pin-type BRB abbreviation of a kind of peg type combination PBRB.
Background technology
Anti-buckling support is a metalloid surrender type damper, is to utilize kernel steel member to bear most axial force at confining part internal freedom ground dilatation, produces surrender and dissipation energy.
Summary of the invention
Be difficult to satisfy control for the damping of reinforced concrete frame structure on engineering for existing anti-buckling support and realize, the present invention proposes the anti-buckling support of a kind of peg type combination.
For achieving the above object, design scheme of the present invention is as follows: the anti-buckling support of peg type combination, comprise kernel steel plate 1, side stay steel plate 2, lateral restraint channel-section steel 3, and kernel steel plate 1 is between two side stay steel plates 2; Lateral restraint channel-section steel 3 is buckled in respectively on the upper and lower surface of kernel steel plate 1 and side stay steel plate 2, and one deck non-cohesive material is pasted on kernel steel plate 1 surface; The inboard two ends of kernel steel plate 1 symmetry is offered circular groove, and through slot is offered at the two ends of lateral restraint channel-section steel 3; Pin 5 embeds in the circular groove of kernel steel plate 1 and through slot that lateral restraint channel-section steel 3 is offered fixing, high-strength bolt 4 alongst fixation side to constraint channel-section steel 3 and pre-pressing kernel steel plate 1 and side stay steel plate 2.When small stratified deformation occurs in structure under the frequently occurred earthquake effect, utilize pin 5 to make the effect of the common support of anti-buckling support performance, increase substantially its initial stiffness; Larger stratified deformation occuring under the rarely occurred earthquake effect when structure, after cutting off pin 5, make anti-buckling support be in state of activation, then passes through many ripples flexing earthquake energy of kernel steel plate 1.
Described pin 5 materials are the Q235 steel.
Kernel steel plate 1 two ends arrange changeover portion, and lateral restraint channel-section steel 3 is offered the large 0.1mm of radius of circular groove 5 on the radius ratio kernel steel plate 1 of through slot.
Paste one deck non-cohesive material between core steel plate 1 and side stay steel plate 2,
Described non-cohesive material is silica gel.
Such tectonic type possesses following advantage: kernel steel plate and side stay steel plate can be formed through cutting by the monoblock steel plate, and gap width between the two can accurately be controlled, but and economical with materials; The outsourcing confining part is connected to form integral body by bolt, can avoid welding the distortion that causes, and affects machining accuracy; Pin is symmetrically arranged in and supports two ends, because confining part is not established outer addition of constraints, sets up after pin and can prevent that confining part from along back shaft to any slip, having played the effect of limiting card under little displacement.
Effect of the present invention and benefit be, satisfied the needs that machining accuracy is controlled when having improved the initial stiffness of anti-buckling support, the realization for anti-buckling support applications in the reinforced concrete frame structure engineering and promote significant.

The specific embodiment
Narrate preferred forms of the present invention below in conjunction with concrete technical scheme and accompanying drawing 1:
The anti-buckling support of peg type combination as shown in Figure 1, comprise kernel steel plate 1, side stay steel plate 2, lateral restraint channel-section steel 3, be primarily characterized in that: lateral restraint channel-section steel 3 is buckled in respectively on two surfaces up and down of kernel steel plate 1 and side stay steel plate 2, and one deck non-cohesive material is pasted on kernel steel plate 1 surface.The inboard symmetry in kernel steel plate 1 two ends is offered circular groove and is packed with pin 5, and lateral restraint channel-section steel 3 is offered through slot in the relevant position.Pin embeds in the groove that kernel steel plate 1 and lateral restraint channel-section steel 3 offer fixing, high-strength bolt 4 along its length fixation side to constraint channel-section steel 3 and pre-pressing kernel steel plate 1 and side stay steel plate 2.When small stratified deformation occurs in structure under the frequently occurred earthquake effect, utilize pin 5 to make the effect of the common support of anti-buckling support performance, increase substantially its initial stiffness; After larger stratified deformation occurs under the rarely occurred earthquake effect, cutting off pin 5, make anti-buckling support be in state of activation when structure, then pass through many ripples flexing earthquake energy of kernel steel plate 1.Do not interspace between channel-section steel and kernel steel plate, to prevent that kernel steel plate is in weak axial many ripples flexing and cripling.The side stay steel plate is when making with assembling, and needing according to designing requirement is that vertically moving with the pressurized lateral deformation of steel core reserved suitable space.Can be connected by junction plate the pre-embedded steel slab of agent structure Nodes and connect in the kernel steel plate two ends with bolt, linkage section need be established the floor of putting more energy into and prevent the end capacity compression buckling failure.
