Description

Technical Field

[0001] The utility model belongs to the technical field of building seismic isolation, and in particular relates to a wind-resistant device for buildings. Background Art

[0002] With the continued expansion of the global construction industry, the number of various construction projects continues to increase. This is particularly true in urban areas, where large-scale construction projects such as high-rise buildings and large commercial complexes are proliferating. These buildings typically have large wind-exposed areas and are taller, making them more susceptible to strong winds. To ensure the stability and safety of buildings in strong winds, the demand for wind-resistant devices has also increased accordingly. For example, in coastal cities frequently hit by typhoons, new high-rise buildings are generally required to install wind-resistant devices to withstand strong winds.

[0003] Currently, ordinary seismic isolation rubber bearings lack wind resistance and are prone to displacement under wind loads. Lead cores provide a certain degree of wind load resistance, but their placement should be limited, as they increase the horizontal stiffness of the isolation layer and affect the horizontal isolation effect. Therefore, wind-resistant devices are necessary. Currently, various wind-resistant devices are available on the market, all of which, in addition to their primary function of wind resistance, also offer the added feature of being replaceable.

[0004] The currently available wind-resistant devices generally consist of two connecting plates plus a middle wind-resistant key, and a fixed seat structure for fixing the wind-resistant key. The proposed replaceability is to replace the wind-resistant key by changing the form of the fixed seat to achieve the replaceable function of the wind-resistant device.

[0005] The existing wind-resistant device structure does not reflect the characteristics of the wind-resistant device. If the wind-resistant device is sheared during an earthquake, the friction or collision between the wind-resistant keys due to the back-and-forth displacement cannot be solved. In another case, there will be a certain amount of displacement between the piers after the earthquake. If the wind-resistant keys are simply replaced, the displacement difference may cause the upper and lower positions of the wind-resistant keys to be out of line, making it impossible to directly replace the wind-resistant keys.

[0027] It should be noted that, in the absence of conflict, the embodiments and features of the embodiments in this application can be combined with each other. The present invention will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0028] Example 1

[0029] refer to Figures 1 to 4 , a wind-resistant device for a building, comprising:

[0030] Upper connecting plate 1, which is fixedly connected to the upper building structure;

[0031] The upper fixing seat 2 is arranged on the lower side of the upper connecting plate 1, and the upper end of the upper fixing seat 2 is fixedly connected to the upper connecting plate 1;

[0032] The lower fixing seat 4 is arranged opposite to the upper fixing seat 2;

[0033] The wind-resistant key 3 is arranged between the upper fixing seat 2 and the lower fixing seat 4, and the two ends of the wind-resistant key 3 are respectively inserted into the upper fixing seat 2 and the lower fixing seat 4. The wind-resistant key 3 is detachably connected to the upper fixing seat 2; a gap is left between the lower fixing seat 4 and the wind-resistant key 3;

[0034] During specific implementation, there are gaps between the lower fixing seat 4 and the surrounding and bottom surfaces of the anti-wind key 3 .

[0035] During specific implementation, the gap around the lower fixed seat 4 and the anti-wind key 3 is small, ensuring that the anti-wind key 3 falls smoothly. The gap between the lower fixed seat 4 and the bottom surface of the anti-wind key 3 is large, ensuring that the lower half of the anti-wind key 3 falls into the lower fixed seat 4 after being cut off.

[0036] The lower connecting plate 6 has a through hole at its center, and the lower end of the lower fixing seat 4 is adjustable and arranged in the through hole. The lower connecting plate 6 is fixedly connected to the lower building structure.

[0037] After the wind-resistant key of the utility model is cut off, the lower part of the wind-resistant key can be directly dropped off, thereby avoiding friction and collision after an earthquake.

[0038] If the utility model has a displacement deviation of 7 after an earthquake, the lower fixing seat can be adjusted so that the wind-resistant keys that have been displaced are still in the same straight line, and the wind-resistant keys can be replaced.

[0039] Preferably, threaded holes are provided on all four sides of the lower connecting plate 6, and the lower connecting plate 6 and the lower fixing seat 4 are fixed by bolts.

[0040] During specific implementation, the lower connecting plate 6 and the lower end of the lower fixing seat 4 may be fixed via a detachable pad, or may be fixed via other forms.

[0041] In this embodiment, the bolt is a hexagon socket bolt 5, but may also be other types of bolts.

[0042] In this embodiment, a gap is left between the upper fixing seat 2 and the upper end of the anti-wind key 3 .

[0043] In this embodiment, a wedge-shaped opening is provided in the middle of the wind-resistant key 3 .

[0044] In this embodiment, the lower end of the lower fixing seat 4 is flush with the lower end of the lower connecting plate 6 , and all four corners are rounded structures.

[0045] In specific implementation, when the building structure is subjected to wind load, the wind-resistant key can bear part of the wind load, thereby avoiding the horizontal force of the isolation support. When subjected to a strong earthquake, the wind-resistant key is cut off first, which will not affect the horizontal displacement of the isolation support.

[0046] When a large earthquake occurs, the wind-resistant keys are sheared off and the isolation bearing begins to move horizontally. The lower half of the shear-resistant keys will fall directly into the lower fixed seat, avoiding the friction and collision between the shear-resistant keys when the bearing moves, thereby ensuring that the horizontal displacement of the isolation bearing will not be obstructed after shearing.

[0047] After an earthquake, if the wind-resistant key is damaged and no displacement occurs, the wind-resistant key can be directly replaced. If displacement occurs, the displacement can be preliminarily measured. After measuring the displacement, the position of the lower fixing seat can be adjusted by bolts (or the size of the pad can be adjusted). After adjusting to the appropriate position, the wind-resistant key can be installed to replace the wind-resistant device.

[0048] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Those skilled in the art will readily appreciate that various modifications and variations are possible. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present invention are intended to fall within the scope of protection of the present invention.
