Abstract
The invention discloses a multi-pipe lattice type buckling-restrained brace, which comprises a core plate, two filling plate strips and two pieces of multi-pipe lattice type restraining components, wherein the two filling plate strips are at two side edges of the core plate; and the two pieces of the multi-pipe lattice type restraining components are arranged at the upper sides and the lower sides of the filling plate strips and the core plate. The multi-pipe lattice type buckling-restrained brace provided by the invention has the advantages that the problems that the buckling-restrained brace has great self weight, and materials of the restraining components accounts for great proportion in the whole brace are solved; the earthquake disaster influence on the engineering structure is reduced; and meanwhile, the damage condition of the core plate of the buckling-restrained brace after the earthquake can also be conveniently observed.
Description
Technical field
The invention belongs to field of civil engineering, relate to a kind of for reducing the buckling restrained brace of engineering structures earthquake disaster impact.
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, China in engineering generally the buckling restrained brace of application mostly formed by the core component of peripheral fill concrete steel tube confinement parts and uniaxial force, as the technical scheme providing in patent of invention openly (as CN100560884C etc.).But concreting curing time is long in above-mentioned buckling restrained brace, can have a strong impact on buckling restrained brace make efficiency.Therefore, in order to overcome the problems referred to above, the present invention and openly patent of invention (as CN101798851B etc.) propose to adopt single sleeve pipe to retrain core component.
But according to the technical scheme that openly patent of invention (CN101798851B) provides, in the time that buckling restrained brace is applied to bridge or large-span structure, in order to improve the resistance to overturning of support, the cross section of confinement sleeve will inevitably be larger, the scale of construction of concrete filled can increase, its deadweight meeting, along with span significantly increases, increases difficulty to construction.Secondly, the cross section increase of confinement sleeve can make sleeve pipe cripling more easily occur, thereby causes integral rigidity to reduce.
In addition, according to the technical scheme that openly patent of invention (as CN100560884C, CN101798851B etc.) provides, be difficult to afterwards observe the damage status of buckling restrained brace inner core core in shake, thereby after giving shake, maintenance causes difficulty.
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, and a kind of multitube lattice buckling restrained brace is provided.
The technical solution used in the present invention is: a kind of multitube lattice buckling restrained brace, comprises core board, filling-in board and multitube lattice constraint component;
Described multitube lattice constraint component is two, is separately positioned on the upper and lower both sides of filling-in board and core board; Described multitube lattice constraint component comprises two parallel sleeve pipes and link, and link is longitudinally distributed between two sleeve pipes, and affixed with two sleeve pipes.
As preferably, the cross sectional shape of two sleeve pipes of described multitube lattice constraint component is rectangle or polygon or fan-shaped, and a face of sleeve pipe is plane, is close to the constraint of core board, and sleeve pipe is hollow section, can fill concrete or mortar in hollow section.
As preferably, the link of described multitube lattice constraint component can be lacing or batten plate or both has, and is distributed between two sleeve pipes, affixed with two sleeve pipes respectively.
As preferably, the lacing of described multitube lattice constraint component can parallel distribution or V-arrangement distribute.
As preferably, the spacing between described two parallel sleeve pipes is greater than 1/3 of core board width, is less than core board width, and two sleeve pipes only contact with the constraint of core board.
As preferably, sleeve pipe and the filling-in board of described multitube lattice constraint component are longitudinally affixed.
As preferably, the sidewall of described multitube lattice constraint component is provided with multipair bolt block, and the bolt block arranging in multitube lattice constraint component passes filling-in board by bolt and is fastenedly connected.
The present invention has following beneficial effect:
1, the present invention is compared with traditional buckling restrained brace, constraint component does not have the whole core board of Complete Bind, sleeve pipe only retrains the constraint at core board edge along core component width, middle part not constrain width is about 4～8 times of thicknesss of slab, contrasts traditional buckling restrained brace, makes the material of constraint component be distributed in as far as possible the outermost of constraint component under the prerequisite of same material consumption, ensureing, under the prerequisite of binding effect, to have realized the maximization of material use efficiency; On the other hand, the raising of constraint component material use efficiency also makes constraint component account for the proportion of whole support to reduce with respect to traditional buckling restrained brace, thus the deadweight that has alleviated buckling restrained brace.Can alleviate like this buckling restrained brace and produce the technical barriers such as amount of deflection is large, constructional difficulties in the middle deadweight of the large-span structures such as bridge, also can be used to develop light-duty buckling restrained brace, thereby expanded the range of application of buckling restrained brace.
2, compared with traditional buckling restrained brace that the present invention retrains core component with the single sleeve pipe of employing, in the time that the cross section of single sleeve pipe constraint component increases, easily there is cripling, finally cause the integral rigidity of single sleeve pipe constraint component to reduce, and the lattice constraint component that the present invention proposes is made up of multitube, casing profile size reduces relatively, thereby has reduced the risk of constraint component generation cripling.
3, the present invention is not because core component mid portion has restrained, so can directly observe the degree of impairment of the rear core component of shake, after having solved traditional buckling restrained brace shake, assess the problems such as difficulty, for the maintenance of buckling restrained brace brings very big facility, significantly reduce the extra charge that buckling restrained brace causes due to the rear assessment difficulty of shake.
4, its material is mainly common iron, the facility of drawing materials, and cost is lower, and the process-cycle is short; All parts all can machine at millwork, having assembled and be transported to job site installs, concreting curing time length in traditional buckling restrained brace, the problems such as difficulty of vibrating are avoided, significantly improve the make efficiency of buckling restrained brace, made buckling restrained brace adapt to the requirement of industrialization of construction industry.
