Engineering field.
Background technique
With the quickening of urbanization process, the development of building field and technical level are constantly promoted, in addition environmental pollution and
The defect of the influence of problem of resource waste, feature of environmental protection difference existing for traditional architecture system gradually exposes, green assembling type steel structure,
Start to become the main Types of building system.Compared with traditional system, the system construction quality, in terms of,
All have significant advantage." playing with building blocks " is a kind of representative construction method, largely accelerates speed of application,
Engineering funds are saved.It applies it in the design and development of all kinds of building systems, is the main of building field future development
Trend.
Conventional frame support system use linear type diagonal brace, structure centre position punch place there are space it is smaller, but
In practical structures engineering problem, many structures need windowing, enabling hole, need biggish hole, then conventional frame support system
It cannot meet the requirements, and easily at structure a certain position buckling failure occurs for conventional frame support system diagonal brace without energy consumption section.Tradition
Unreasonable the occurrence of will lead to " strong component weak bus " is designed at support body framework binder Column border node, makes structure in earthquake lotus
Load effect is lower to occur serious earthquake, threatens people life property safety.Add existing research shows that carrying out specific aim to bean column node
It by force or takes weakening means to can reach the purpose of plastic hinge specific region on beam, to protect bean column node, meets " strong
The design requirement of the weak component of node "；Meanwhile floor and beam section it is pre-assembled after be transported to construction site carry out assembly can greatly save it is existing
The time of field concreting；In addition, without repairing or slightly repairing the recoverable function that can restore using function after earthquake
Structure is the research hotspot of International Seismic engineering field in recent years, and the lives and properties of people can not only be protected to pacify in earthquake
Entirely, and after earthquake it can also restore it as early as possible using function, therefore need to implement the theory of recoverable function structure in new
Structure R & D design work in, with realize building from it is single pursuit collapse resistant capacity to take into account shake after can repair ability turn
Become.
In order to overcome the problems referred above, the invention patent proposes the recoverable function steel frame of a kind of big headroom and flange plate
Central supported system.It is board-like by the way that top flange connecting plate is arranged to inner cover, when inner cover plate deforms, inner cover plate can with fall
The contact of L type web shear plate is held out against, and inverted L shape web shear plate can control the bending deformation of top flange cover board, realize anti-buckling
Purpose；By the way that dissipative cell is arranged at diagonal brace, dissipative cell absorbs energy when diagonal brace stress, prevents diagonal brace from unstability occurs broken
Bad, structure entirety lateral resisting improves, can be in the position of setting support while improving structure entirety lateral resisting, overall stability
It sets and opens up door opening, keep design form more flexible, be able to satisfy different structure form.
Summary of the invention
The present invention proposes the recoverable function steel frame central supported system of a kind of big headroom and flange plate, it is intended to solve

There is a dissipative cell, dissipative cell absorbs energy by therein bending deformation when diagonal brace stress, promotes diagonal brace bearing capacity, can
Prevent diagonal brace from unstable failure occurs, diagonal brace system is more stable, while dissipative cell can realize Fast Installation by attachment device,
Realize the anti-buckling support of assembled, structure entirety lateral resisting improve, improve structure entirety lateral resisting, overall stability it is same
When, door opening can be opened up in the position of setting support, keep design form more flexible, be able to satisfy different structure form；The system
Bean column node connection has recoverable function after shake, realizes that beam-ends is reinforced by thickening cantilever beam section edge of a wing thickness, passes through cover board
Connection type and cantilever beam section and I-shaped beam section between gap setting, reach plastic hinge and improve turning power mesh
, so that plastic failure occurs in splice region, and elasticity is kept substantially in bean column node rest part, connection need to be only replaced after shake
Device can restore the use function of main structure；The design of inverted L type web shear plate, can buckling width to top flange cover board
Value is controlled；Top flange connecting plate is arranged to that inner cover is board-like, and when inner cover plate deforms, inner cover plate can be with inverted L shape web
Shear plate contact is held out against, and inverted L shape web shear plate can control the bending deformation of top flange cover board, realize anti-buckling purpose；Beam
Column connected node is connected using cover board, and top flange cover board uses inner cover plate design, convenient for the connection with floor, lower flange cover board
Using outer cover plate design.
A kind of recoverable function steel frame central supported system of big headroom and flange plate, it is characterised in that: Y type diagonal brace
It is connect with each main component by attachment device, forms a kind of support system, while which guarantees bearing capacity, and it is same
When can be in the position opening holes of setting support, design method is flexible, be able to satisfy the needs of different structure form, and the support by
Each component meets the advantages of assembling type steel structure is constructed to be bolted.
Each component of the device is all formed by factory process, and scene is connected by high-strength bolt entirely and installed, it is easy to accomplish component adds
