Description
Technical Field
The invention relates to a shock insulation and absorption structure for fixing a building, in particular to an anti-locking one-way sliding shock absorption hinged support.
Background
The existing support node usually adopts a plate spring to realize buffering for dynamic load. For example, a document with a publication number of CN 204385607U discloses an anti-seismic connecting seat, as shown in fig. 1 to 2, the anti-seismic connecting seat is buffered by using a leaf spring 70 in both the forward and transverse bridge directions, and when an earthquake occurs, the end of the leaf spring 70 receives an excessive instantaneous dynamic load, and the end of the leaf spring 70 scratches the inner side wall of the box 10 at a high frequency, so that the inner side wall of the box 10 is scraped to form a stepped protrusion, and the movement of the end of the leaf spring 70 is hindered by the protrusion when the leaf spring extends and retracts, so that the lower support 20 is locked by the box 10, and the anti-seismic function is lost.
In a high-rise connected building, under a common condition, two tower buildings and a high-altitude gallery bridge between the two tower buildings are connected through a support node, because a corridor on a high rise is positioned in the high air and clamped between the two tower buildings, the wind load is very large, the wind vibration of the high-rise tower buildings can also generate horizontal power amplification on the corridor, if the corridor is a multilayer corridor, the problem is more serious because the corridor has a larger wind receiving area, so that the static load and the dynamic load of the gallery bridge have larger adverse effects on the support node and on a monomer and the gallery bridge, and particularly under the action of the dynamic load similar to the wind load, the mutual effects of the tower buildings and the gallery bridge are difficult to eliminate.
If the anti-seismic connecting base is used as a support of a gallery bridge in a high-rise connected building, the wind power in the high air is larger than the ground and the wind direction changes more frequently, the end part of the transverse plate spring 70 scratches the inner side wall of the box body 10 continuously under the action of the transverse bridge wind load of the gallery bridge for a long time, the strength and hardness of the plate spring steel are far higher than those of the box body 10, and the end part of the conventional finished plate spring of the support is a sharp right angle, so that the inner side wall of the box body 10 is scratched to form a stepped protrusion, the movement of the end part of the plate spring 70 is blocked by the protrusion when the plate spring extends and retracts, the lower support 20 is blocked by the box body 10, and the gallery bridge is blocked by the support. And once the gallery bridge is blocked by the support, the influence by the wind load for a long time again leads to easily that the shaft bolt that is used for fixing plate spring 70 receives the shear fracture, and then makes plate spring 70 loose the frame, and finally whole antidetonation connecting seat loses antidetonation function.
In addition, because the rigidity of the plate spring is low, when the gallery bridge in the high air encounters a large wind load, the vibration of the gallery bridge relative to the tower is superposed with the vibration of the tower to generate a whip effect, so that the gallery bridge shakes violently, and therefore, in practice, a support which slides in one direction is generally adopted in a high-rise building, namely, a plate spring is not arranged in the transverse bridge direction of the support, and the transverse bridge direction of a gallery bridge body is directly rigidly restrained. Under the action of wind load or earthquake load, the vibration of each tower is inevitably asynchronous, and the two ends of the gallery bridge respectively move along with the corresponding tower to generate torsion and translation, so that the displacement difference between the gallery bridge node and the one-way sliding support is caused, and the displacement difference is particularly obvious for the oblique crossing connected structure. However, the rigidity of the transverse bridge is restricted, and the unidirectional sliding support cannot melt the displacement difference between the gallery bridge node and the unidirectional sliding support, so that the gallery bridge body is locked relative to the tower when encountering strong wind and strong shock, and the support or the bridge body structure of the gallery bridge is damaged under the condition that two towers are twisted, thereby causing more serious consequences.
