Change, production plant, construction assembling, the advantages that greening building energy saving is environmentally friendly.Wherein, the connection type of component occupies important
A ring.Traditional steel frame often uses the mode of welding in work progress at the scene, but due to construction site environment complexity,
So that the bad assurance of construction quality of welding, being bolted preferably to carry out control to construction quality, but exists centainly
Design difficulty.How welding is stayed in the better factory of working environment to carry out, is only bolted at the construction field (site), is
Major issue in prefabricated construction field.
Existing more high-rise public buildings and residential housing will lead to building and terminate use once seismic Damage occurs, right
Social economy restores and people's life will cause to seriously affect, and the repair after shake is even more time-consuming and laborious.How to pass through
Reasonable Frame Design not only can guarantee collapse resistant capacity of the structure in earthquake, but also can reduce the warp of repairing and reinforcement after structure shake
Help cost and time cost, realize after the shake of building structure function can fast quick-recovery, be the Important Problems of structural seismic research.
In order to overcome the problems referred above, this patent proposes a kind of Self-resetting frame center supporter with end plate connecting node
System.The bolted on part fastening work of component is convenient and efficient, accelerates speed of application, and using the high-strength spiral shell at connecting plate
Bolt friction energy-dissipating avoids the damage of the main components such as beam column.When geological process occurs, anti-buckling support can play good energy consumption
Effect, while I-shaped beam section can automatically restore to original position under the action of drag-line.
Summary of the invention
A kind of Self-resetting frame center support system with end plate connecting node proposed by the present invention, geological process occur
When, anti-buckling support can play the role of good energy consumption, while general I-shaped beam section can automatically restore to original under the action of drag-line
Position.
To achieve the above object, the present invention uses following technological means:
A kind of Self-resetting frame center support system with end plate connecting node, it is characterised in that: it is characterized in that the body

One of, the cantilever beam section in the square steel tube center pillar with cantilever beam section is closely connect by beam column node connection device with I-shaped beam section,
The combination of cover board and drag-line can improve the total bearing capacity of node and be avoided that drag-line prestressing force is to work in combination automatic runback device
The overstressing load of word beam section；Cantilever beam-ends and I-shaped beam-ends in square steel tube center pillar with cantilever beam section are all welded with end plate,
Beam column node connection device is assisted to carry out the square steel tube center pillar with cantilever beam section and the company between the I-shaped beam section with inclined support bar
It connects, the connection of end plate can reduce the rotation displacement of I-shaped beam section generation；Cantilever beam in square steel tube center pillar with cantilever beam section
Section is held out against with I-shaped beam section, is left no gaps after installation, is avoided that the loss of prestress due to caused by beam-ends rotation displacement, drag-line
Effect can control the accumulation of development and the damage of plastic deformation, thus the anti-seismic performance and reset capability of lift structure；And it is described
The combination automatic runback device and anti-buckling support work together, and drag-line and anti-buckling support collective effect realize Self-resetting effect；
The energy dissipation capacity of anti-buckling support reduces the operating pressure of drag-line, improves the stability and self-resetting capability of structure.
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 by I-shaped beam section and two the second inclined support bars with two
The first attachment device of group is formed by connecting；The combination automatic runback device includes two toolings, a drag-line and two beam column sections
Point attachment device；The system is symmetrically arranged, and two square steel tube center pillars with cantilever beam section combine square steel tube with two welding
Column passes through two group of second attachment device connection respectively；Two square steel tube center pillars with cantilever beam section are located at inclined support bar
I-shaped beam section both ends are connected by two beam column node connection devices with two End plate connections, the side with cantilever beam section respectively
Cantilever beam section in steel pipe center pillar is held out against with I-shaped beam section, does not stay seam after being installed, in the cantilever beam section welding tooling, is used for
Stay guy and preventer guy apply pretension；Described two anti-buckling supports pass through four groups of third attachment devices and welding respectively
Quadrate steel pipe column and the I-shaped beam section connection with inclined support bar are combined, anti-buckling support lower end combines the first of quadrate steel pipe column with welding
Inclined support bar is connected by third attachment device, and anti-buckling support upper end passes through third attachment device and the I-shaped with inclined support bar
The second inclined support bar connection in beam section.
The advantages of this patent, is mainly manifested in the following aspects:
1, combination automatic runback device includes two toolings, a drag-line and two beam column node connection devices, is drawn with tradition
Rope automatic runback device is compared, in the identical situation of drag-line pretension, using the entirety of the bean column node of combination automatic runback device
Bearing capacity can be higher；In the identical situation of bearing capacity of bean column node, the drag-line prestressing force demand meeting of automatic runback device is combined
It reduces, is avoided that the excessive overstressing load to I-shaped beam section of drag-line prestressing force；By rationally designing Suo Li size, make structure most
The accumulation for controlling to big degree development and the damage of plastic deformation, makes structure have good anti-seismic performance and reset capability.
2, Self-resetting after shaking.Anti-buckling support and drag-line collective effect, cooperate.It is anti-buckling when geological process occurs
Support can play the role of good energy consumption, greatly reduce earthquake load bring influence, when earthquake load cause it is bigger
When influence, I-shaped beam section can automatically restore to original position under the action of drag-line, realize runback bit function after antidetonation and shake.
