Abstract
The utility model discloses an earth quake-resisting safety mechanism with frictional shear articulation which is suitable for the rigidity pull level and pressure lever support system of a frame structure and a bent structure of the industrial and civil buildings with single floor and multi-floor in the earthquake region. A frictional shear articulation is arranged at the intersection point of the rigidity cross support. The fastening force of a high-strength bolt is used to slide for energy consumption under the strong earthquake force. The utility model is characterized in that the earth quake-resisting safety mechanism with frictional shear articulation is suitable for the frame structure and bent structure of steel and steel reinforced concrete. Thereby, the application range is enlarged.
Description
The utility model is that hinge quake-resistant safety device is sheared in a kind of improved friction, is applicable to earthquake zone individual layer and multilayer, industry and civilian frame, bent structure rigidity are drawn, the depression bar support system.
In the prior art, resist quiet horizontal force performance good though normal crossing supports, under brisance acted on repeatedly doughtily, because the depression bar lateral deflection, pull bar produced reasons such as plastic strain and Bauschinger effect, will produce the slippage degradation phenomena.After promptly being supported on several times repeatedly horizontal force action, the power consumption function reduces greatly, and just plays the power consumption effect when the big displacement of agent structure.Therefore, normal crossing is supported under the brisance effect doughtily and itself will destroys, and agent structure also can not get fine protection.Support the anti-seismic performance deficiency in order to overcome normal crossing, having multiple pattern power consumption to support occurs, shear having aspect the hinge in rigid support friction and at K shape support node place the metal friction is installed and shears hinge, utilize high-strength bolt to fasten and resist the sliding quake-resistant safety device of seismic energy that consumes strenuously.See " Response of friction damped braced frames " Journal of the structural division, ASCE. June 1982.PP1313～1323。
When the earthquake horizontal force surpass high-strength bolt fasten power the time, the high-strength bolt power consumption of in the bar shaped slip hole, sliding.Because sliding is to carry out at steel and steel surface, so the horizontal Beam of level that K shape is supported is steel Beam.Frame, bent structure also are limited to steel frame, bent structure.
Task of the present utility model is to make a kind of quake-resistant safety device, and it can be applicable to, and earthquake zone individual layer and multilayer, industrial and civilian steel and steel reinforced concrete frame, bent structure rigidity are drawn, the depression bar support system.
Task of the present utility model is finished as follows:
One by post (1), the frame that Beam (2) forms, in the bent structure, punish at the intersection point of rigidity cross support, (about also can being divided into) two partly down, on, two partly respectively with last down, under save plate and connect, on, under save plate and be the horizontal steel plate welding of two blocks of vertical steel plates and, on the horizontal steel plate of last joint plate, have four bar shaped slip holes, on the level board that saves plate down, have four bolts hole, bolt hole is corresponding up and down with the position of slip hole, to go up with high-strength bolt, under save that plate connects and fastening, when tighting a bolt, produce a kind of skid resistance of fastening, when earthquake horizontal force during less than the skid resistance fastened, stress performance is the same with common rigid support, when the earthquake horizontal force surpassed the skid resistance of fastening, high-strength bolt slided in the bar shaped slip hole on last joint plate, reached the purpose that consumes seismic energy.
The utility model is applicable to earthquake zone individual layer and multilayer, industry and civilian frame, bent structure, on the equipment supporter structural system that also can be used for resonating, to reduce dynamic response, protection equipment.
The utility model is sheared hinge with the friction of K support metal and is compared, applied range, and the frame of steel and steel concrete, bent structure all are suitable for.
Below with reference to accompanying drawing the utility model is described in further detail.
Fig. 1 is the installation drawing of a kind of concrete form of the present utility model.
Fig. 2 is plane, facade, the side view of last joint plate.
Fig. 3 is for saving plane, facade, the side view of plate down.
With reference to Fig. 1,2,3, one by post (1), the frame that Beam (2) is formed, in the bent structure, intersection point place in rigidity cross support (3), support is divided into, (about also can being divided into) two partly down, two supports (3) of the first half are connected with last joint plate (4), last joint plate (4) is two vertical metal plate same level metal sheet welding, have four bar shaped slip holes (7) (see figure 2) on the level board, two supports (3) of lower portion are connected with following joint plate (5), under to save plate (5) also be the welding of two vertical metal plate same level metal sheets, have four bolts hole (8) (see figure 3) on the level board.Press frame, bent structure that Fig. 1 installs, high-strength bolt (6) is used nut screwing clamping.
Claims (3)
1, a kind of by post (1), Beam (2), rigidity draw, depression bar support (3), on save plate (4), save the metal friction that plate (5), high-strength bolt (6) form down and shear hinge quake-resistant safety device, it is characterized in that with the metal friction shear that hinge is installed in that rigidity is drawn, on the intersection point of depression bar cross support.
2, hinge quake-resistant safety device is sheared in described metal friction according to claim 1, it is characterized in that rigidity cross support (3) is punished into upper and lower (or about) two partly at intersection point, two supports (3) on top are connected with last joint plate (4), last joint plate (4) is two vertical metal plate same level metal sheet welding, have (7) four of bar shaped slip holes on the level board, two supports (3) of bottom are connected with following joint plate (5), under to save plate (5) also be the welding of two vertical metal plate same level metal sheets, have (8) four of circular bolt holes on the level board.
