Description
Technical Field
The invention relates to a tool for building damping engineering, in particular to a repeatedly-usable bidirectional unhooking device with tensile resistance and wind resistance.
Background
The seismic isolation structure can achieve the purpose of effectively reducing the seismic action by prolonging the structure period. The shock insulation support has better compression resistance and deformation capacity and certain horizontal lateral stiffness resistance. The smaller the lateral stiffness is, the longer the structural period is, the more obvious the damping effect is, but when the lateral stiffness is smaller, the deformation of the structure is overlarge under wind load, and the use function of the building is influenced to a certain extent, so that certain contradiction exists between earthquake resistance and wind resistance on the stiffness requirement of the support.
In order to effectively guarantee the shock absorption effect of shock insulation, some scholars propose a shock-resistant and wind-resistant separation method. The shock insulation layer is additionally provided with a wind resisting device, the wind resisting device provides lateral rigidity under the action of wind load, but under the action of earthquake load, the wind resisting device fails, and only the shock insulation support plays a role in energy consumption. The existing wind-resistant device is generally realized by weakening one part of a steel member, and a preset weakened part is broken under the action of wind load, so that the work is quitted.
The method is feasible theoretically, but has great defects in actual engineering, on one hand, because steel has certain ductility, on the other hand, the earthquake is complex, the stress of a steel member is complex, and the preset fracture is difficult to realize, the rigidity of a seismic isolation layer is great during the earthquake, and the good seismic isolation effect is difficult to realize.
In addition to the problem of wind resistance, the seismic isolation bearing has a problem that the bearing is relatively tensile. Once the tensile support is easy to break, some scholars propose anti-pulling devices which can play a certain anti-pulling effect, but the device has a single function and high cost.

Referring to fig. 1-2, the reusable anti-tensile and anti-wind bidirectional unhooking device comprises a shock insulation support 6, a connecting support 5, a movable hook 3, a rotating hook 1, a slide block 4, a pin shaft 2, a pull rod 9 and a sleeve 10, wherein the shock insulation support 6 is arranged between the upper portion and the lower portion of a shock insulation layer 12, the slide block 4 and the connecting support 5 are arranged between the upper portion and the lower portion of the shock insulation layer 12, the rotating hook 1 is arranged on the slide block 4, the rotating hook 1 is connected with the rotating hook 3 at two ends of the rotating hook 1, the connecting support 5 is connected with the upper portion of the shock insulation layer 12 and is in rigid connection, the slide block 4 is connected with the lower portion of the shock insulation layer 12, the slide block 4 can be made of steel or concrete, the rotating hook 1 is connected with the connecting support 5 through the pin shaft 2, the pin shaft is detachable, the movable hook 3 is connected with a lower pier 7 of the shock insulation support 6, the pull rod 9 is arranged at the lower portion of the connecting support 5, the pull rod 9 is arranged inside the sleeve 10, and the sleeve 10 is connected with the lower portion of the pull rod 9.
The movable hook 3 is connected with the lower buttress 7, and a certain included angle is formed between the movable hook 3 and the horizontal direction and is preferably 3 to 10 degrees.
The end parts of the movable hook 3 and the rotating hook 1 are both provided with a semi-arc structure 11, and the semi-arc structure can facilitate the mutual close occlusion of the three. The movable hook 3 and the rotating hook 1 are meshed together through a semicircular arc structure and are tightly attached to the sliding block.
The wind-resistant device has the fixed-point unhooking effect, and the fixed-point unhooking is that when the deformation reaches a certain degree, the rotating hook 1 separates the rotating hook 1 from the moving hook 3 under the self-weight effect.
The wind-resistant device has a pull-out stiffness which is formed by the pull rod 9 and the sleeve 10 being in close contact.
The sliding block 4 is symmetrically provided with the movable hook 3 and the rotating hook 1, and the symmetric arrangement can provide equivalent tensile rigidity during bidirectional deformation.
As shown in figure 3, the sleeve 10 and the pull rod 9 freely slide in the horizontal direction and freely move downwards, after the upward displacement reaches a certain value, the sleeve 10 and the pull rod are in close contact, the free sliding is realized by a groove 13 at the upper part of the sleeve 10, the length of the groove of the sleeve 10 is larger than the diameter of the pull rod 9, and the width of the groove is smaller than the diameter of the pull rod 9.
The implementation method comprises the following steps:
s1, firstly, calculating deformation under the action of air load according to a structural model, thereby determining the contact length between a sliding block 4 and a rotating hook 1 along the length direction of the rotating hook 1, and calculating the area and the length of a connecting support 5 and the hook according to the rigidity requirement;
s2, determining the positions of the connecting support 5, the sliding block 4, the movable hook 3, the pull rod 9 and the sleeve 10 according to the size of the shock insulation layer, and fixing the connecting support and the sleeve with the structure;
s3, arranging the rotating hook 1 between the sliding block 4 and the movable hook 3;

When the shock insulation layer moves left and right under the action of wind load, the movable hook 3 and the rotary hook 1 are connected together and symmetrically arranged on two sides, so that tensile rigidity is formed on one side, and rigidity is not provided on the other side.
When one side deforms too much and exceeds the contact surface of the sliding block 4 and the rotating hook 1, the rotating hook 1 rotates around the center of the pin shaft under the action of self weight, so that the moving hook 3 is separated from the rotating hook 1, the lateral stiffness of the rotating hook 1 on one side is released, and when the other side deforms too much, the rotating hook 1 on the other side can also fall off from the moving hook 3, so that the stiffness is completely released; when the structure is deformed in a large vertical direction, the pull rod 9 is lifted up and contacts the sleeve 10 after being lifted to a certain degree, so that the pulling-resistant rigidity is formed, and the tensile stress of the support is reduced.

The shock insulation structure has the advantages that the structure deformation is limited when wind is resisted, so that the shock insulation layer has a larger rigidity requirement, the support is required to have better deformation and energy consumption capacity when the shock insulation structure is resisted, so that the shock insulation layer has a smaller rigidity requirement, and the rigidity requirements of wind resistance and shock resistance on the shock insulation layer are in certain contradiction.
