Abstract
The invention discloses a buckling restrained brace embedded with light material bodies, a casing and concrete. The buckling restrained brace comprises a core part, the light material bodies, the outer casing and concrete or mortar blocks, wherein a plurality of light material bodies are distributed on the periphery of the core part respectively; the outer casing is placed on the peripheries of the core part and the light material bodies; and gaps among the outer casing, the core part and the light material bodies are filled with the concrete or mortar blocks. According to the invention, the light material blocks or hollow cavities are preliminarily embedded into the casing filled with concrete, and the use amount of filled concrete is reduced; and according to the method that the light material blocks or the hollow cavities are embedded, the dead weight of the whole support can be reduced by reducing the weight of restraining parts under the condition that the influence on the buckling restrained brace performance is smaller.
Description
Technical field
The invention belongs to field of civil engineering, relate to a kind of for reducing buckling restrained brace of engineering structures earthquake disaster impact and preparation method thereof.
Background technology
Buckling restrained brace is a kind of device that utilizes metal yield dissipation seismic energy, due to its stable performance, easy to make, with low cost, has obtained in recent years studying widely and applying.
At present, the buckling restrained brace that China generally applies in engineering is made up of concrete filled steel tube confinement parts and the core component that bears axial force mostly, for example discloses the technical scheme providing in patent of invention (CN100560884C).Constraint component is not directly born axial load, can suppress outside the low order flexing of core component under pressure-acting, and core component is total cross-section surrender under pulling force and pressure-acting, and member hysteresis loop is full.For ensureing that overall unstability does not occur buckling restrained brace under axial compression effect, constraint component cross section should have larger moment of inertia, so constraint component material usage is a lot, finally causes whole buckling restrained brace deadweight larger.Particularly, in the time that buckling restrained brace is applied to bridge or large-span structure, the overall bending resistance demand of its constraint component can increase and improve along with span, and constraint component sectional dimension and deadweight also can increase, and increase difficulty to construction.
Summary of the invention
The present invention accounts for the heavy problem of whole support in order to solve buckling restrained brace from great, constraint component material, provides and has buried light material body cover pipe concrete buckling restrained brace in a kind of.
The technical solution used in the present invention is: in one, bury light material body cover pipe concrete buckling restrained brace, comprise core component, light material body, outer tube and concrete or mortar piece;
Described light material body is polylith, is distributed in respectively around core component, and described outer tube is positioned over the periphery of core component and light material body, is filled with concrete or mortar piece between outer tube 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, is symmetrically distributed in respectively two surfaces of core component, a surface label of light material body is at core component width middle part, and this face width is less than core component width.
As preferably, the cross section of described core component is in-line, described light material body is four, be symmetrically distributed in respectively two surfaces of core component, a surface label of light material body is in core component widthwise edges, and the spacing between homonymy two light material bodies is greater than 1/3 of core component broadside.
As preferably, the cross section of described core component is cross, and form four breach, described light material body is four, cross section is less than breach cross section, symmetrical being placed with in the described breach of core component respectively, two surface labels of every light material body core component breach surface, and breach forming section is filled.
As preferably, the cross section of described core component is I-shaped, and form two breach, described light material body is two, cross section is less than breach cross section, symmetrical being placed with in breach described in the I-shaped cross-section of core component respectively, three surface labels of light material body core component breach surface, and breach forming section is filled.
As preferably, the cross section of described core component is in T shape, and form two breach, described light material body is two, cross section is less than breach cross section, symmetry is placed with the described breach at core component respectively, and two surface labels of every light material body core component breach surface, and breach forming section is filled.
As preferably, the cross-sectional form of described outer tube is polygon or circle.
The present invention by imbedding in advance light material block or hollow cavity in the sleeve pipe of concrete filled, reduce the consumption of concrete filled, the method of burying light material block or hollow cavity in proposing according to the present invention, can, less to buckling restrained brace performance impact in the situation that, reduce the deadweight of whole support by reducing constraint component weight.
The present invention has following beneficial effect:
1, the present invention is compared with traditional buckling restrained brace, concrete or mortar are not full of the space between core board and outer tube completely, concrete or mortar do not have the whole core board of Complete Bind, only retrain core component constraint, middle part not constrain width is about 4～8 times of thicknesss of slab, ensureing under the prerequisite of binding effect, realize the maximization of material use efficiency, making constraint component account for the proportion of whole support further reduces with respect to traditional buckling restrained brace, thereby significantly alleviate the deadweight of buckling restrained brace, can solve buckling restrained brace large in the middle deadweight generation amount of deflection of the large-span structures such as bridge, the key issues such as constructional difficulties, can be used to develop light-duty buckling restrained brace, greatly expand the range of application of buckling restrained brace.
2, the buckling restrained brace of the present invention's proposition is simple in structure, the support manufacturing method flow providing is simple and easy, and easy construction only need be on the basis of traditional buckling restrained brace, paste light material block on core component surface, just can significantly alleviate buckling restrained brace deadweight; Core component of the present invention can be multiple section form: in-line, cross, I-shaped and T font, comprised the main section form of having applied buckling restrained brace core board at present, the buckling restrained brace that therefore the present invention proposes has extremely wide range of application.
