Abstract
The invention discloses a casing pipe concrete buckling restrained brace with embedded light material bodies. The casing pipe concrete buckling restrained brace with the embedded light material bodies comprises a core part, the light material bodies, an outer casing pipe and concrete or mortar blocks. The plurality light material bodies are distributed around the core part, the outer casing pipe is arranged at the periphery of the core part and the light material bodies, and the concrete or mortar blocks are filled between the outer casing pipe and the core part and the light material bodies. According to the casing pipe concrete buckling restrained brace with the embedded light material bodies, by pre-embedding the light material bodies or hollow-cavity bodies inside the casing pipe with in-fill concrete, the amount of the in-fill concrete can be saved, and the self-weight of the brace can be reduced by reducing the weight of restraining parts under the condition of having little influence on the performance of the buckling restrained brace.
Description
Technical field
The invention belongs to field of civil engineering, relate to a kind of buckling restrained brace be used to reducing the impact of engineering structures earthquake disaster 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 using.
At present, the buckling restrained brace that China generally uses on engineering is comprised of concrete filled steel tube confinement parts and the core component that bears axial force mostly, for example discloses the technical scheme that provides 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 the total cross-section surrender under pulling force and pressure-acting, and the member hysteresis loop is full.For guaranteeing that whole unstability does not occur buckling restrained brace under the axial compression effect, the constraint component cross section should have larger moment of inertia, so the constraint component material usage is a lot, finally causes whole buckling restrained brace deadweight larger.Particularly when buckling restrained brace was applied to bridge or large-span structure, the whole 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 for 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: bury light material body cover pipe concrete buckling restrained brace in a kind of, 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 the 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 the 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 the breach cross section, symmetry is placed with in the described breach of core component respectively, and it is surperficial that two surface labels of every light material body the core component breach, and the 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 the breach cross section, symmetry is placed with in the described breach in the I-shaped cross-section of core component respectively, and it is surperficial that three surface labels of light material body the core component breach, and the 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 the breach cross section, symmetry is placed with the described breach at core component respectively, and it is surperficial that two surface labels of every light material body the core component breach, and the breach forming section is filled.
As preferably, the cross-sectional form of described outer tube is polygon or circle.
The present invention is 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 in the situation that less to the buckling restrained brace performance impact, reduce the deadweight of whole support by reducing constraint component weight.
The present invention has following beneficial effect:
1, the present invention compares with traditional buckling restrained brace, concrete or mortar are not full of the space between core board and outer tube fully, concrete or mortar do not have the whole core board of Complete Bind, only retrain the core component constraint, middle part not constrain width is about 4～8 times of thicknesss of slab, under the prerequisite that guarantees binding effect, realized the maximization of material use efficient, making constraint component account for the proportion of whole support further reduces with respect to traditional buckling restrained brace, thereby significantly alleviated 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 expanded 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 that provides is simple and easy, and easy construction only needs on the basis of traditional buckling restrained brace, at core component surface stickup light material block, just can significantly alleviate the buckling restrained brace deadweight; Core component of the present invention can be the multiple section form: in-line, cross, I-shaped and T font, comprised the main section form of having used the buckling restrained brace core board at present, so the buckling restrained brace that the present invention proposes has extremely wide range of application.
