Description
Technical field
The present invention relates to Self-resettings after a kind of shake can assemble multistage joist steel frame, belongs to protection against and mitigation of earthquake disasters technical field.
Background technique
Japanese steel house accounts for 60% or more of whole houses, and multiple earthquake proves that steel building is mixed relative to reinforcing bar
The anti-seismic performance that solidifying civil engineering is built greatly improves, and difficulty is repaired after shake and is substantially reduced.Therefore need to greatly develop steel building, especially
It is that high in technological content steel structural form should more obtain paying attention to and develop.
Steel construction prestressing technique is quickly grown, wherein most representative is Beijing University of Technology Gymnasium, the shop
Suspended-dome structure application prestressing technique reaches slim and graceful, energy-efficient effect, and domestic more well-known universities and colleges are large-span prestressed
Steel structure system novel aspects have innovative research.But in frame structure system, application is answered in advance especially at local nodes
Power technical research is seldom, and depth is far from enough.
High-strength tear-resistant silicon rubber is a kind of special synthetic rubber, has excellent thermal adaptability, chemical stabilization
Property and fire prevention, nontoxic feature, especially its tear resistance and tensile strength obtain mentioning greatly very much compared to traditional natural rubber
2000N/CM can be obtained in height, tensile strength2, in fields such as national defense industry, aviation, space travel, electric appliance, medical instruments, application is wide
It is general, but using still category blank in building structure, but high-intensitive, the high expansion and contraction itself having and its nontoxic characteristic of preventing fires
Meet requirement of the building structure to civil engineering material, should try to explore to make its excellent performance be not fully exerted using approach.
Summary of the invention
The invention proposes Self-resettings after a kind of shake for belonging to protection against and mitigation of earthquake disasters technical field can assemble multistage joist steel frame.Its
Purpose is to improve frame structure ductile performance and then improves structural seismic performance, repairs difficulty and maintenance cost after reducing shake,
Reduce the construction period, reduces cost of labor.Self-resetting can assemble multistage joist steel frame and be constituted substantially including frame column, node after shake
The components such as beam, intermediate beam, prestressed cable, bean column node connector and beam beam joint.Sequence of construction: first install bean column node,
Mounting rail girder connection again.Specific configuration is in the construction process, first to install the top-seat-angle steel at bean column node, then install beam column
I-steel web-angle at node, after bean column node installation, mounting rail girder connection: the web connecting plate of first mounting rail girder connection,
Top bottom high-strength tear-resistant silicane rubber plate and sealing plate are installed again, finally install simultaneously tensioning to high-strength prestressed rope, pre-
Beam beam contact surface generates compressive pre-stress under the action of stress cable stretching power, and this compressive pre-stress will provide biggish for beam girder connection
Resist torque greatly improves bonding strength, and the web connecting plate of Liang Liangjiedianchu effectively increases web thickness, is Liang Liang
Node provides biggish resistance shearing.
Self-resetting can assemble multistage joist steel frame basic principle after shake: when geological process reaches middle shake level, Liang Liangjie
Contacting surface takes the lead in opening, and moderate finite deformation and earthquake energy occurs in high-strength silicone rubber, so as to avoid main components such as beam columns
Damage.After geological process, structure is restored to shake under the convergent force effect of the pretension and high-strength silicone rubber of prestressed cable
Front position.Studies have shown that the combination of the high-strength silicone rubber and prestressed cable of the junction Liang Liang is under normal use working condition
It can achieve the intensity of welding, the amount of deflection generated in use process, which is less than, standardizes defined maximum defluxion；It is high under geological process
Strength silicone rubber and prestressed cable can play its excellent telescopicing performance, absorb seismic energy, and then protect bean column node
Shield, meets the design concept of " strong node, weak component " and " strong column and weak beam ".
The application of prestressed cable and high-strength silicone rubber enables steel-frame structure to obtain preferable anti-seismic performance and higher
Safety coefficient.Self-resetting can assemble the major advantage of multistage joist steel frame after shake: (1) combination of new technology and new material
Make steel frame have better anti-seismic performance, prestressing technique application make shake after repair difficulty substantially reduce, angle of displacement compared with
The present invention can realize Self-resetting using the elastic shrinkage ability of prestressed cable and high-strength silicone rubber in the case where small, without repairing
It is multiple；(2) it can achieve the intensity of welding under normal use working condition, the amount of deflection generated in use process is less than as defined in specification
Maximum defluxion；(3) mainly by high-strength bolt connection, construction site do not have welding, more not conventional concrete construction
Wet construction, process is easy, environmentally protective, is bolted and mores easily guarantee construction quality, avoid because construction personnel individual's quality is not high,
Welding material is bad, robs the generation that weldquality difference caused by the reasons such as work in turn results in architecture quality safety accident；(4) full spiral shell
Bolt type of attachment can realize the batch production manufacture of building structure, prefabricated construction, substantially reduce duration cost and cost of labor.
Self-resetting can assemble multistage joist steel frame after the shake, according to position difference, the joint form packet of steel frame
Three kinds of specifications are included, respectively L shape node connects, the connection of T-section point, crisscross joint connection；
