Description

Technical Field

[0001] The present invention relates to the technical field of prefabricated buildings, and specifically to an adjustable shock-absorbing base for prefabricated buildings. Background Art

[0002] A prefabricated building refers to a building assembled on-site with prefabricated components. The advantages of this type of building are fast construction speed, little restriction by climatic conditions, labor saving, and improved building quality. Due to the fast construction speed and low production cost of prefabricated buildings, they have been rapidly promoted. Currently, most prefabricated buildings use support seats for support work.

[0003] Most of the existing support seats for prefabricated buildings use simple rigid connections and lack effective shock-absorbing functions. Under the action of earthquakes, strong winds or other external forces, the building structure is prone to stress concentration due to vibration, resulting in component damage or even overall structural instability. Therefore, an adjustable shock-absorbing base for prefabricated buildings is needed. Summary of the Invention

[0004] Aiming at the deficiencies of the prior art, the present invention provides an adjustable shock-absorbing base for prefabricated buildings, which solves the problem that most of the existing support seats for prefabricated buildings use simple rigid connections and lack effective shock-absorbing functions.

[0005] To achieve the above objectives, the present invention is realized through the following technical solutions: An adjustable shock-absorbing base for prefabricated buildings, comprising: A connecting frame, which is connected to the building pillar of the prefabricated building through an adjustable fixing frame to adapt to installation with building pillars of different specifications; A buffer frame, located at the bottom side of the connecting frame. A chassis is provided at the bottom side of the buffer frame. A plurality of first-level buffer heads are installed on the top side of the buffer frame to timely feedback through the abutting disc fixed to the bottom side of the connecting frame when the connecting frame vibrates, and reduce the force generated by the vibration. The first-level buffer heads will immediately transmit the force to the second-level buffer heads after being stressed to further reduce the force generated by the vibration. The second-level buffer heads are installed inside the chassis, and after the vibration is eliminated, the chassis slows down the reset speed of the first-level buffer heads and the second-level buffer heads through the stable reset heads to avoid secondary vibration caused by too fast reset; The middle of the top side of the chassis is connected to the center of the bottom side of the abutting disc through a spring damper shaft two. The inner walls of the four corners of the buffer frame and the chassis are connected through telescopic rods.

[0006] Preferably, the primary buffer head includes a hydraulic cylinder fixedly connected to the top side of the buffer frame. Two openings one are provided on the top side of the hydraulic cylinder, and one opening two is provided on the bottom side of the hydraulic cylinder. A correction head is slidably connected inside one of the openings one, and an abutting head is slidably connected inside the other opening one. A transmission head is slidably connected inside the opening two through a spring. The interior of the hydraulic cylinder is filled with hydraulic oil. The top end of the abutting head abuts against the bottom side of the abutting disc, and the correction head is located on the outer periphery of the bottom side of the connecting frame.

[0007] Preferably, the hydraulic cylinders are equidistantly arranged around the bottom side of the connecting frame to precisely reduce the force in a specific direction.

[0008] Preferably, a telescopic sleeve is sleeved on the side of the transmission head close to the opening two to protect the spring.

[0009] Preferably, the secondary buffer head includes a contact head fixedly connected to the bottom side of the transmission head and a sliding seat fixedly connected to the outer periphery of the bottom side of the inner wall of the chassis. A sliding frame is slidably connected inside one end of the sliding seat. The top side of the sliding frame is connected to the contact head through a connecting rod. One end of the connecting rod is rotatably connected to the top side of one end of the sliding frame, and the other end of the connecting rod is rotatably connected to the bottom side of the contact head. The other end of the sliding frame is sleeved with a housing. The bottom side of the housing is fixedly connected to the bottom side of the inner wall of the chassis. A magnetic sheet two is fixedly connected to the inner wall of the housing. A magnetic sheet one is fixedly connected to one side of the sliding frame. Both the magnetic sheet one and the magnetic sheet two are made of magnets, and the similar sides of the magnetic sheet one and the magnetic sheet two repel each other with the same polarity.

[0010] Preferably, sliding rails are fixedly connected to both sides of the other end of the sliding seat, and sliding heads are fixedly connected to both sides of one end of the contact head. The sliding heads are slidably connected inside the sliding rails.

[0011] Preferably, the stable reset head includes a reset head. The side of the reset head away from the contact head is connected to the middle end inside the chassis through a spring damper shaft one. Slopes are provided on the similar sides of the reset head and the contact head, and the two slopes abut against each other.

[0012] Preferably, the adjustment fixing frame includes a threaded disc rotatably connected inside the connecting frame and four fixing frames slidably connected to the top side of the connecting frame. Threads are provided on the top side of the threaded disc. The bottom sides of the fixing frames are slidably connected inside the threads. The fixing frames and the building support column are fixed through stud nuts.

[0013] Preferably, a force application groove is provided at the center of the threaded disc to facilitate applying force to rotate the threaded disc.

[0014] Preferably, fixing holes for assisting in installing and fixing the shock absorption base on the ground are provided at the four corners of the bottom end of the chassis.

[0015] Working principle: When the building pillar is stressed, the abutting disc at the bottom side of the connecting frame connected to the building pillar undergoes a certain offset and vibration, applying a force to the abutting head in the direction of the stress, causing the abutting head to displace inside the hydraulic cylinder and compress the spring damper shaft II, dispersing and consuming the initial force, reducing the impact brought by the vibration. The stressed abutting head pushes the hydraulic oil inside the hydraulic cylinder to push the transmission head and the correction head. The pushed transmission head pushes the abutting head at the bottom end to displace. The reset head abutted by the upper inclined surface of the abutting head loses the abutment of the abutting head and is gradually reset under the reset push of the compressed spring damper shaft I. When the abutting head displaces obliquely downward, it will push the carriage to slide on the slide seat through the connecting rod, and then push the magnetic sheet I connected to it to slide inside the housing and gradually enter the repulsion range of the magnetic sheet II. Under the action of the magnetic repulsion of the magnetic sheet II, the force is dispersed and eliminated. The displaced correction head will rise, enabling the correction head to apply a force to the outer peripheral edge of the bottom side of the connecting frame, thereby preventing the further angular offset of the connecting frame and the structure connected to the top side of the connecting frame due to the further shaking caused by the vibration. After the vibration disappears, the abutting disc no longer applies a force to the previously displaced abutting head. The abutting head is lifted and reset, and applies a force to the reset head through the inclined surface, compressing the spring damper shaft I, enabling the abutting head to be slowly reset, avoiding the occurrence of secondary vibration caused by too fast reset. Subsequently, the magnetic sheet I and the spring damper shaft II are reset and restored to calm.

[0016] The present invention provides an adjustable shock-absorbing base for prefabricated buildings. It has the following beneficial effects: 1. Through the synergistic effect of the primary buffer head and the secondary buffer head, the present invention realizes multi-stage reduction of vibration. The surrounding design can target the force from a specific direction, more effectively protecting the building structure from the influence of vibration.

[0017] 2. Under the slow reset mechanism of the stable reset head, the present invention avoids secondary vibration caused by too fast reset, significantly improving the stability and safety of the building. Moreover, the correction head timely lifts in the direction of vibration to support the bottom edge of the connecting frame, preventing excessive offset of the structure due to further shaking caused by the vibration.

[0018] 3. The present invention can adjust the distance between the fixing frames through simple rotation operations, thus adapting to building pillars of different specifications. Construction workers only need to use bolts and nuts to complete the fixation of the building pillar and the fixing frame, with simple operation and no need for additional adaptation measures.

The bottom side of the fixed frame 23 is gradually subjected to the threaded force along with the rotation of the thread, and thus displacement occurs. According to the counterclockwise and clockwise directions of the thread rotation, multiple fixed frames 23 perform a closing movement or a dispersing movement until the distance between multiple fixed frames 23 is suitable for the insertion of the building pillar 4. After the insertion is completed, the building pillar 4 and the fixed frame 23 are fixed through stud nuts.

Force is applied to the abutting head 7 in this direction according to the stress direction, so that the abutting head 7 displaces inside the hydraulic cylinder 6.
