Background technique
Different from traditional welding or bolted bean column node, Self-resetting prestress steel frame structure system utilizes height
The pretension of intensity prestress wire come make main structure formed runback bit function, be able to bear biggish elastic-plastic deformation,
With good ductility.Lateral deformation can be generated in seismic process, after geological process power disappears, due to high-intensitive pretension
In the presence of lateral deformation being made to disappear, the form before making structure be restored to earthquake.Self-resetting steel-frame structure and rigid connection frame phase
It is more essentially identical than being deformed in earthquake, but residual deformation very little after shake.Since main structure enters plastic region in seismic process
It is smaller, it is weaker to will lead to main structure energy dissipation capacity.
Self-resetting prestress steel frame structure system, which generallys use, at present is anchored at the prestress wire at girder steel both ends and makes
Overall structure has runback bit function.But anchorage and steel strand wires price are generally more expensive, and the reliability of anchorage with
Its quality is closely related, once anchorage fails, will directly result in the failure of prestress wire, and then cause total
It collapses.In addition, relaxing and creeping for prestress wire also results in the decline of steel frame runback bit function.From construction angle and
Speech, prestress wire need to carry out tensioning in the construction process, have higher requirement to construction machinery and construction environment, unfavorable
In going on smoothly for construction.
Summary of the invention

The present invention provides a kind of Self-resetting steel-frame beam column connected nodes.
To achieve the goals above, the present invention adopts the following technical scheme:
A kind of Self-resetting steel-frame beam column connected node, including steel pipe column and with the girder steel of end plate, the steel pipe column is left
Right side wall is symmetrically opened up there are four circle screw hole, opens up that there are four justify screw hole, the steel on the end plate of the girder steel with end plate
Tubing string left and right sidewall is fixedly mounted by double threaded screw and marmem high-strength spring with the girder steel with end plate, and double
Head screw rod runs through steel pipe column and the girder steel with end plate simultaneously, and the double threaded screw stretches out the girder steel partial outer face for having end plate
It is arranged with marmem high-strength spring, and marmem high-strength spring one end is pasted with the girder steel with end plate
It closes, the other end is bonded with nut, and the steel pipe column is provided with and rubs with the girder steel top flange and lower flange angle for having end plate
Wipe energy-consuming device.
The friction energy consuming device includes two with circle screw hole steel plate, two rubber spacers and with oval screw hole steel plate, institute
It states friction energy consuming device to be welded on steel pipe column side wall by band circle screw hole steel plate, the friction energy consuming device passes through with oval spiral shell
Hole steel plate is welded in the steel beam flange with end plate, and band oval screw hole steel plate both ends are provided with rubber spacer, two rubber pads
Layer outer end is provided with band circle screw hole steel plate, and passes through high-strength bolt with oval screw hole steel plate, rubber spacer and with circle screw hole steel plate
It is fixedly mounted.
The steel pipe column is set as the combined steel pipe column of rectangle hollow steel pipe column or internal casting concrete.
The girder steel with end plate is set as H profile steel beam or i-shape steel beam.
The invention has the benefit that
1, double threaded screw utilizes increased marmem high-intensitive while offer girder steel vertical shear-carrying capacity
Spring provides steel frame and the self- recoverage power after sidesway occurs, and this avoid making for high-strength prestress steel strand wires and anchorage
With greatly reducing the difficulty of construction and project cost of engineering.
2, steel frame is made to improve node while possessing runback bit function using the friction energy consuming device in bean column node corner
Whole energy dissipation capacity；Friction energy consuming device construction is simple of the present invention can be completed by welding and tightening bolt at the scene
Installation, so it is of less demanding to the technical level of master worker.
