Description
Technical field
The invention belongs to field of civil engineering, relate to a kind of for reduce engineering structure earthquake disaster impact buckling-restrained
Support and preparation method thereof.
Background technology
Buckling restrained brace is a kind of device utilizing metal yield dissipation seismic energy, due to its stable performance, making side
Just, with low cost, obtained in recent years studying widely and applying.
At present, the buckling restrained brace that China is commonly used in engineering is mostly by concrete filled steel tube confinement parts and holding
Formed by the core component of axial force, the technical scheme be given in the most disclosed patent of invention (CN100560884C).About
Bundle parts the most directly bear xial feed, can suppress the low order flexing of core component under external pressure effect, and core component exists
Total cross-section surrender under pulling force and pressure effect, component hysteresis loop is full.Buckling-restrained for ensureing under axial compressive force effect
Supporting does not occurs overall collapse, constraint component cross section should have bigger the moment of inertia, so constraint component material usage is a lot,
Ultimately result in the deadweight of whole buckling restrained brace bigger.Particularly it is applied to bridge or large-span structure when buckling restrained brace
Time, the overall bending resistance demand of its constraint component can increase along with span and improve, constraint component sectional dimension and deadweight
Also can increase, increase difficulty to construction.
Summary of the invention
The present invention is to solve that buckling restrained brace accounts for the heavy problem of whole support from great, constraint component material, carry
Supplied a kind of in bury light material body set pipe concrete buckling restrained brace.
The technical solution used in the present invention is: bury light material body set pipe concrete buckling restrained brace in one, including core
Heart parts, light material body, trocar sheath and concrete or mortar block；
Described light material body is polylith, is respectively distributed to around core component, described trocar sheath be positioned over core component and
The periphery of light material body, is filled with concrete or mortar block between trocar sheath and core component, light material body.
As preferably, described light material body cross section is polygon, semicircle or fan-shaped, and described light material body is light
Material block or hollow cavity.
As preferably, the cross section of described core component is in-line, and described light material body is two pieces, is respectively symmetrically point
Cloth is on two surfaces of core component, and a surface of light material body is attached in the middle part of core component width, this surface
Width is less than core component width.
As preferably, the cross section of described core component is in-line, and described light material body is four pieces, is respectively symmetrically point
Cloth is on two surfaces of core component, and a surface of light material body is attached to core component widthwise edges, homonymy two
Spacing between light material body is more than the 1/3 of core component broadside.
As preferably, the cross section of described core component is cross, and forms four breach, and described light material body is
Four pieces, cross section is less than breach cross section, is respectively symmetrically and is placed with in the described breach of core component, every piece of light material
Two surfaces of body against core component breach surface, fill breach forming part.
As preferably, the cross section of described core component is I-shaped, and forms two breach, and described light material body is
Two pieces, cross section is less than breach cross section, is respectively symmetrically and is placed with in breach described in the I-shaped cross-section of core component, gently
Three surfaces of material body against core component breach surface, fill breach forming part.
As preferably, the cross section of described core component is in T shape, and forms two breach, and described light material body is
Two pieces, cross section is less than breach cross section, is respectively symmetrically and is placed with the described breach at core component, every piece of light material body
Two surfaces against core component breach surface, to breach forming part fill.
As preferably, the cross-sectional form of described trocar sheath is polygon or circle.
The present invention, by imbedding light material block or hollow cavity in the sleeve pipe of concrete filled in advance, fills out mixed in minimizing
The consumption of solidifying soil, the method burying light material block or hollow cavity according to the present invention in proposing, can be to flexing about
In the case of bundle branch support performance impact is less, reduce the deadweight of whole support by reducing constraint component weight.
The method have the advantages that
1, the present invention is compared with tradition buckling restrained brace, and concrete or mortar are not completely filled with core board and trocar sheath
Between space, concrete or mortar do not have the whole core board of Complete Bind, a constraint core component constraint, middle part
The most about beam width is about thickness of slab 4～8 times, on the premise of ensureing binding effect, it is achieved that the maximization of material use efficiency,
The proportion making constraint component account for whole support reduces further relative to tradition buckling restrained brace, thus significantly reduces
The deadweight of buckling restrained brace, it is possible to resolve buckling restrained brace produces that amount of deflection is big in the middle deadweight of the large-span structures such as bridge, executes
The key issues such as work difficulty, can be used to develop light-duty buckling restrained brace, are greatly enlarged the application model of buckling restrained brace
Enclose.
2, the simple in construction of buckling restrained brace that the present invention proposes, it is provided that support manufacturing method flow simple, construction
Convenient, only need to be on the basis of tradition buckling restrained brace, at core component surface mount light material block, the most permissible
Significantly alleviate buckling restrained brace deadweight；The core component of the present invention can be multiple section form: in-line, cross,
I-shaped and T-shaped, contain the major section form having applied buckling restrained brace core board at present, the therefore present invention
The buckling restrained brace proposed has the widest range of application.
