Description
Technical field
The present invention relates to the recoverable function steel frame eccentrical braces of a kind of big headroom and flange plate, belong to structure
Field of engineering technology.
Background technique
Since reform and opening-up, China makes remarkable achievements in urban construction field, at the same time, high energy consumption,
High pollution, the extensive build model of inefficient tradition are still more universal, the hair with novel urbanization, industrialization, informationization
Exhibition requires far apart.Change the production method of existing building industry, Development of Green Building is to lead the new normality of economic development and reality
The grand strategy of existing sustainable development.Assembling type steel structure building have standardized designs, the factorial production, prefabricated construction,
The features such as integration finishing, information system management, be the green building in life cycle management.Assembling type steel structure is widelyd popularize to build
Build, it is possible to reduce building waste and building dust pollution, shorten construction duration, promoted construction quality, digestion steel superfluous production capacity,
Form steel strategic reserves.
Assembling type steel structure building system has become the new direction and new trend of construction steel structure development, has design standard
Change, production plant, construction assembling, the advantages that greening building energy saving is environmentally friendly.Existing more high-rise public buildings and house are built
It builds, once seismic Damage occurs, will lead to building and terminate use, social economy's recovery and people's life will be caused serious
It influences, the repair after shake is even more time-consuming and laborious, to damage -form after a large amount of building shake studies have shown that the main of structure is broken
Bad form is the destruction at beam-column connection, how by reasonably designing, can improve the energy consumption energy of beam-column connection
Power, and it is able to achieve replaceable after the shake of structural elements, it is the Important Problems of structural seismic research.
In order to overcome the problems referred above, this patent proposes a kind of big headroom and the recoverable function steel frame of flange plate is eccentric
Support system.By the specially treated at beam-column connection, cover board energy consuming can be made and limit cover board deformation, it can
Achieve the purpose that improve ultimate bearing capacity of joints stability and energy dissipation capacity；Active beam link and accentric support design concept are introduced, can be risen
It is acted on to structure " fuse ", changes simultaneously supporting form, door opening can opened up in the position of setting support, save and use steel
Amount, improves economic benefit and applicability.
Summary of the invention
The present invention proposes the recoverable function steel frame eccentrical braces of a kind of big headroom and flange plate, it is intended to improve
The energy dissipation capacity of beam-column connection；A kind of novel support system is introduced simultaneously, it is intended to be solved at frame inward swinging door hole
Problem.
To achieve the above object, the present invention uses following technological means:
A kind of recoverable function steel frame eccentrical braces of big headroom and flange plate, it is characterised in that: the system
Including two welding combination quadrate steel pipe columns, two square steel tube center pillars with cantilever beam section, two I-shaped beam sections with inclined support bar,
Two Y type diagonal braces, an active beam link and several attachment devices；The system and steel truss support and steel truss tube structure system
It compares, while improving structure entirety lateral resistance behavior, door opening can be opened up in the position of setting support；The system beam column section
Point attachment device has recoverable function after shake, thick by the cantilever beam section edge of a wing in the square steel tube center pillar of thickener belt cantilever beam section
Degree realizes that beam-ends is reinforced, the connection type by cover board and cantilever beam section and I-beam in the square steel tube center pillar with cantilever beam section
Gap setting between section achievees the purpose that plastic hinge and improves turning power, and plastic failure is only sent out under earthquake load
Life keeps elasticity in rest part in splice region, and only need to replace beam column node connection device can restore main structure after shake
Use function；The design of inverted L shape web connecting members, can the buckling amplitude to top flange cover board control effectively；Top flange
Cover board is arranged to that inner cover is board-like, and when inner cover plate deforms, inner cover plate can be contacted with inverted L shape web connecting members and be held out against, inverted L shape
Web connecting members can limit the bending deformation of top flange cover board, realize anti-buckling purpose.
The described welding combination quadrate steel pipe column is by the upper quadrate steel pipe column of flange plate, middle quadrate steel pipe column, cantilever beam section and the
One inclined support bar is welded；The I-shaped beam section with inclined support bar is connected by I-shaped beam section and the second inclined support bar with first

The gap of 5-20mm guarantees that I-shaped beam section has turning power, and the gap between top flange cover board and inverted L shape web connecting members is
5-10mm, guarantee can make cover board energy consuming and limit cover board deformation, to promote the stability and consumption of ultimate bearing capacity of joints
It can ability；Edge of a wing cover board uses inner cover plate design, and convenient for the connection with floor, lower flange cover board uses outer cover plate design,
The bolt unsymmetrical arrangement at cantilever beam section and I-shaped beam section lower flange in square steel tube center pillar with cantilever beam section, it is therefore intended that
Cantilever beam section lower flange cover board is first installed, lower flange cover board can be used as the rest of I-shaped beam section during the installation process, accelerate construction
Speed improves construction quality.
The system introduces active beam link design concept simultaneously, sets accentric support for anti-side device, active beam link plays
The effect of structure " fuse ", under violent earthquake load action, structure carries out energy dissipation, beam, column also by active beam link
It will not be surrendered in advance with support main member.
The advantages of this patent, is mainly manifested in the following aspects:
1, the design of inverted L shape web connecting members is led to after the cover board buckling of top flange using anti-buckling theory in the system
It crosses and is held out against with the contact on the inverted L shape web connecting members edge of a wing and can mention enough support forces for edge of a wing cover board, to the buckling width of top flange cover board
Value control effectively, while can improve the energy dissipation capacity of beam-column connection, keeps ultimate bearing capacity of joints more stable.
2, the system forms a kind of new support system by Y type diagonal brace and each main component and attachment device, with steel truss
Bracing Systems, steel truss tube structure system are compared, can be in setting branch while improving structure entirety lateral resistance behavior
The position of support opens up door opening, keeps design form more flexible, has more applicability.
3, to be arranged to inner cover board-like for top flange cover board in the system, and concrete outside top flange can be made more smooth, and bottom wing
Edge cover board is arranged to that outer cover is board-like, can be used as the rest of I-beam during the installation process, while being also convenient for node in use process
In edge of a wing cover board bending deformation is observed, the with good performance visual and replacement property sentenced.
4, each component of the system and nodal connection device welding portion are completed in factory, and weld seam precision and quality is more
Easy to control, each component is assembled only with high-strength bolt in scene, and the fastening work of bolt is convenient and efficient, speed of application and applies
Working medium amount greatly improves, and adapts to the development of assembling type steel structure.
