A kind of combination slot line frame is cut assembling energy-dissipation structure system
Technical field
The utility model relates to a kind of combination slot line frame and cuts assembling energy-dissipation structure system.
Background technology
Earthquake is the mankind to be endangered to one of maximum natural calamity, and earthquake isolation is the emphasis of highly seismic region design of building structures, especially high level and Super High structure.Earthquake isolation is the energy dissipation capacity of building by raising, makes degree of injury and the deformation failure of earthquake to structure reach minimum.
The main frame beam column node of high-rise steel structure full welding or the bolt weldering connected nodes of adopting at present, these two kinds of nodes all need scene to weld more.Under geological process, tend to because commissure stress is concentrated, or even weldquality do not pass a test and cause weld seam to be torn, thereby cause overall structure to lose efficacy.Site Welding needs large number quipments and personnel in addition, and scene fire prevention is had to certain hidden danger.
For shear wall part, the now reinforced concrete shear walls that adopt more, between reinforced concrete shear wall and steel frame due to material property difference thermal response difference, making between the two can not fine collaborative work and stressed work.In addition, the disadvantages affect of structure of reinforced concrete complexity, long construction period the development of high-rise steel structure, steel plate shear force wall can overcome the problems referred to above, minority is applied in high-rise steel structure.But current steel plate shear force wall is all plain plate, in earthquake, flexing is very fast, and lateral resistant ability is limited, and connected mode is welding, again steel plate self is produced to stress and concentrate when strengthening site work amount.
At present tall building structures system is taking cylinder in frame cylinder, bundled tube and cylinder as main, but frame part joint form is single, the concrete shear force wall ductility that shell portion adopts is inadequate again, and energy dissipation capacity deficiency under geological process easily occurs that large fracture, later stage repair and replacing cost is high.In the situation that building height rises, can only deal with by improving section area, and the construction period is often very long.Lack the new structure system that a kind of construction speed is fast, force path is simple, energy dissipation capacity is strong.

Detailed description of the invention
Referring to Fig. 1, in the present embodiment, combination slot line frame is cut the form of structure of assembling energy-dissipation structure system and is: in system, adopt steel core concrete column 1, groove line web beam 2 and groove line steel plate shear force wall 3; Between steel core concrete column 1, groove line web beam 2 and groove line steel plate shear force wall 3, implementing bolt connects; The cross section of groove line web beam 2 is H shape, the frange plate with H tee section groove line web beam 2 is plain plate, web is groove line shape steel plate, groove line web beam changes its web form on the basis of plain edition girder steel, improve its shear-carrying capacity, delay the appearance of node plastic hinge, effectively reduced depth of section; Groove line steel plate shear force wall 3 is groove line shape steel plate, and groove line shape steel plate flexing first under geological process, benefits from groove line cross section, and when its flexing, energy dissipation capacity is strong, still has larger lateral strength after flexing, has significantly improved structure redundancy.
As shown in Fig. 5 a and Fig. 5 b, on the post jamb of steel core concrete column 1, be reserved with bolt hole, in the two ends of groove line web beam 2 welding friction steel plate 5, in friction steel plate 5, leave friction steel plate bolt hole, friction steel plate 5 and groove line web beam 2 co-operation of beam-ends, under geological process, after shear wall flexing, friction steel plate 5 drum before girder steel flexing is bent, in repairing, only needs friction steel plate 5 to change in the later stage.Friction steel plate 5 fits with the sidewall of steel core concrete column 1, and connect by bolt 6, form bean column node, this node connects due to friction steel plate 5 and the friction energy-dissipating of steel core concrete column 1, improve the ductility of structure, it is bent that even if reach ultimate limit states, this node only can be out of shape by end plate, beam-ends flexing develops into post jamb drum, collapse and can there is not agent structure Sudden failure, provide larger escape space and time.This beam column connected mode adopts full bolt to connect without Site Welding work, improves node security reliability.
Shown in Fig. 2, for the steel core concrete column 1 that adopts square-section, friction steel plate 5 is the flat boards that fit with the sidewall of steel core concrete column 1; Shown in Fig. 3, for the steel core concrete column 1 that adopts circular cross-section, friction steel plate 5 is the arcs that fit with the sidewall of steel core concrete column 1.Under geological process, between friction steel plate 5 and steel core concrete column 1 by mutual rubbing action consumed energy.
Shown in Fig. 4, in the present embodiment, on the frange plate of groove line web beam 2, interval is fixedly welded with junction plate 4, is reserved with junction plate bolt hole on junction plate 4; Be in each groove peak at the two ends of the groove line shape steel plate of groove line steel plate shear force wall 3 and trough valley place is reserved with wallboard bolt hole.Junction plate 4 has avoided groove line steel plate shear force wall 3 directly to contact with groove line web beam 2, has eliminated shear wall the stress of girder steel is concentrated.Groove line steel plate shear force wall 3 is to be vertically and to be arranged in framework with groove line, and is connected with junction plate 4 bolts on correspondence position with trough valley position with each groove peak, and junction plate 4 is the same side in steel plate shear force wall 3 all.After groove line steel plate shear force wall 3 is connected with groove line web beam 2 by junction plate 4, general frame is under horizontal force action, girder steel by junction plate 4 by Shear transfer to groove line steel plate shear force wall 3, have benefited from bolt connecting mode between the two, there will not be the unfavorable Joint failure as torn in weld seam, until there are groove line steel plate shear force wall 3 buckling failures.Steel core concrete column 1 is as vertical applied force member, the pulling force field that groove line steel plate shear force wall 3 forms after flexing can exert an influence to steel core concrete column 1 rigidity, therefore between the utility model steel plate shear force wall 3 and steel core concrete column 1, be not directly connected, overcome an above-mentioned difficult problem.
In concrete enforcement, form prefabricated welding unit with groove line web beam 2 and friction steel plate 5, form assembled unit with groove line web beam 2 and junction plate 4, be prefabricated in the factory, this structural system only occurs with steel core concrete column 1, groove line web beam 2 with junction plate 4 and friction steel plate 5 and groove line steel plate shear force wall 3 three parts at the construction field (site); Three parts are all implemented to connect with bolt at the scene, can adopt frictional high-strength bolts, ensure connecting portion reliability on the one hand, utilize on the other hand junction bolt power consumption.Three forms after entirety, and " fuse " that groove line steel plate shear force wall 3 becomes total arranges and dissipative cell, and simultaneously also due to this good ductility in system bean column node place, groove line steel plate shear force wall 3 each member in the time of surrender still can remain on elastic stage.To bear power consumption and lateral resisting at " fuse " the pit line web beam 2 of deactivating, even if groove line web beam 2 and friction steel plate 5 surrenders in succession, structural entity also there will not be interlayer surrender mechanism, has ensured the safety of building.
