Description
Technical field
The utility model belongs to field of civil engineering, relates to a kind of buckling restrained brace for reducing the impact of engineering structures earthquake disaster 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, easy to make, with low cost, obtains investigation and application widely in recent years.
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 bearing axial force mostly, such as discloses the technical scheme provided in utility model patent (CN100560884C).Constraint component does not directly bear axial load, can suppress the low order flexing of core component under external pressure effect, and core component is total cross-section surrender under pulling force and pressure effect, and component hysteresis loop is full.For ensureing that buckling restrained brace overall collapse does not occur 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 to be conducted oneself with dignity larger.Particularly when buckling restrained brace is applied to bridge or large-span structure, the overall bending resistance demand of its constraint component can increase along with span and improve, and constraint component sectional dimension and deadweight also can increase, and increases difficulty to construction.

The utility model accounts for the heavy problem of whole support in order to solve buckling restrained brace from great, constraint component material, provides in one and buries light material body cover pipe concrete buckling restrained brace.
The technical solution adopted in the utility model is: bury light material body cover pipe concrete buckling restrained brace in one, comprise core component, light material body, outer tube and concrete or mortar block;
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 block 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 pieces, is symmetrically distributed in two surfaces of core component respectively, a surface of light material body is attached in the middle part of core component width, 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 pieces, be symmetrically distributed in two surfaces of core component respectively, a surface of light material body is attached to core component widthwise edges, and the spacing between homonymy two light material body 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 pieces, cross section is less than breach cross section, symmetry is placed with in the described breach of core component respectively, and two surfaces of every block light material body against core component breach surface, fill breach forming section.
As preferably, the cross section of described core component is I-shaped, and form two breach, described light material body is two pieces, cross section is less than breach cross section, symmetry is placed with in breach described in the I-shaped cross-section of core component respectively, and three surfaces of light material body against core component breach surface, fill breach forming section.
As preferably, the cross section of described core component is in T shape, and form two breach, described light material body is two pieces, cross section is less than breach cross section, the symmetrical described breach be placed with at core component respectively, two surfaces of every block light material body against core component breach surface, fill breach forming section.
As preferably, the cross-sectional form of described outer tube is polygon or circle.
The utility model by imbedding light material block or hollow cavity in advance in the sleeve pipe of concrete filled, reduce the consumption of concrete filled, according to the method for burying light material block or hollow cavity in the utility model proposes, when less to buckling restrained brace performance impact, the deadweight of whole support can be reduced by reducing constraint component weight.
The utility model has following beneficial effect:
1, the utility model 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, constraint core component constraint, middle part not constrain width is about thickness of slab 4 ~ 8 times, under the prerequisite ensureing binding effect, achieve the maximization of material use efficiency, the proportion making constraint component account for whole support reduces further relative to traditional buckling restrained brace, thus significantly reduce the deadweight of buckling restrained brace, can solve buckling restrained brace conduct oneself with dignity in the large-span structures such as bridge produce amount of deflection large, the key issues such as constructional difficulties, can be used to develop light-duty buckling restrained brace, the very big range of application expanding buckling restrained brace.
The structure of the buckling restrained brace that 2, the utility model proposes is simple, the support manufacturing method flow provided is simple and easy, easy construction, only need on the basis of traditional buckling restrained brace, at core component surface mount light material block, buckling restrained brace deadweight just significantly can be alleviated; Core component of the present utility model 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 buckling restrained brace that therefore the utility model proposes has extremely wide range of application.
