Description

Multi-tube lattice type buckling restrained brace

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.

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 the core component of peripheral fill concrete steel tube confinement parts and uniaxial force mostly, as disclosed the technical scheme provided in utility model patent (as CN100560884C etc.).But concreting curing time is long in above-mentioned buckling restrained brace, buckling restrained brace make efficiency can be had a strong impact on.Therefore, in order to overcome the problems referred to above, the utility model and openly utility model patent (as CN101798851B etc.) propose to adopt single sleeve pipe to retrain core component.

But according to the technical scheme that openly utility model patent (CN101798851B) provides, when 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 significantly can increase along with span, increases difficulty to construction.Secondly, the cross section increase of confinement sleeve can make sleeve pipe cripling more easily occur, thus causes integral rigidity to reduce.

In addition, the technical scheme provided according to openly utility model patent (as CN100560884C, CN101798851B etc.), is difficult in shake the damage status observing buckling restrained brace inner core core afterwards, thus safeguards after giving shake and cause difficulty.

Utility model content

The utility model accounts for the heavy problem of whole support in order to solve buckling restrained brace from great, constraint component material, provides a kind of multi-tube lattice type buckling restrained brace.

The technical solution adopted in the utility model is: a kind of multi-tube lattice type buckling restrained brace, comprises core board, filling-in board and multi-tube lattice type constraint component;

Described multi-tube lattice type constraint component is two, is separately positioned on the upper and lower both sides of filling-in board and core board; Described multi-tube lattice type 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 multi-tube lattice type constraint component is rectangle or polygon or fan-shaped, and a face of sleeve pipe is plane, and be close to the constraint of core board, sleeve pipe is hollow section, can fill concrete or mortar in hollow section.

As preferably, the link of described multi-tube lattice type 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 multi-tube lattice type constraint component can parallel distribution or V-arrangement distribution.

As preferably, the spacing between described two parallel sleeve pipes is greater than 1/3 of core board width, and be less than core board width, two sleeve pipes only contact with the constraint of core board.

As preferably, sleeve pipe and the filling-in board of described multi-tube lattice type constraint component are longitudinally affixed.

As preferably, the sidewall of described multi-tube lattice type constraint component is provided with multipair bolt block, and the bolt block that multi-tube lattice type constraint component is arranged is fastenedly connected through filling-in board by bolt.

The utility model has following beneficial effect:

1, the utility model 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 thickness of slab 4 ~ 8 times, contrasts traditional buckling restrained brace, makes the material of constraint component be distributed in the outermost of constraint component as far as possible under the prerequisite of same material consumption, under the prerequisite ensureing binding effect, achieve the maximization of material use efficiency; On the other hand, the proportion that the raising of constraint component material use efficiency also makes constraint component account for whole support reduces relative to traditional buckling restrained brace, thus alleviates the deadweight of buckling restrained brace.Buckling restrained brace can be alleviated like this to conduct oneself with dignity in the large-span structures such as bridge technical barriers such as producing amount of deflection is large, constructional difficulties, also can be used to develop light-duty buckling restrained brace, thus expanded the range of application of buckling restrained brace.

2, compared with the utility model retrains traditional buckling restrained brace of core component with the single sleeve pipe of employing, when the cross section of single sleeve pipe constraint component increases, easy generation cripling, the integral rigidity of single sleeve pipe constraint component is finally caused to reduce, and the lattice constraint component that the utility model proposes is made up of multitube, casing profile size reduces relatively, thus reduces the risk of constraint component generation cripling.

3, the utility model is because core component mid portion is not restrained, so the degree of impairment of the rear core component of shake directly can be observed, solve the problems such as traditional buckling restrained brace shake later evaluation difficulty, for the maintenance of buckling restrained brace brings great convenience, significantly reduce the extra charge that buckling restrained brace causes due to shake later evaluation difficulty.

4, its material is mainly common iron, facility of drawing materials, and cost is lower, and the process-cycle is short; All parts all can machine at millwork, assemble and be transported to job site to install, avoid concreting curing time length in traditional buckling restrained brace, the problems such as difficulty of vibrating, significantly improve the make efficiency of buckling restrained brace, make buckling restrained brace adapt to the requirement of industrialization of construction industry.
