Description

Technical Field

[0001] This utility model relates to the field of building engineering, and in particular to a prefabricated building connection base. Background Technology

[0002] In prefabricated building construction, the stability and buffering performance of component connections directly affect the overall structural safety of the building.

[0003] Traditional prefabricated building connection bases mostly adopt rigid connection structures, lacking effective buffering and adjustment mechanisms. When encountering earthquakes, foundation settlement, or external load impacts, the connection parts are prone to stress concentration due to rigid compression, leading to problems such as component cracking and loosening of connections. At the same time, existing connection bases are difficult to adapt to small angular deviations during component installation, requiring high installation accuracy and posing significant construction difficulties. Furthermore, they cannot offset the cumulative damage caused by vibration during long-term use, affecting the service life of the building. Therefore, a prefabricated building connection base is proposed to solve the above problems. Summary of the Invention

[0004] To overcome the above deficiencies, this utility model provides a prefabricated building connection base, which aims to improve the problems mentioned above.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a prefabricated building connection base, including a base, wherein a buffer mechanism is provided on the top of the base; The buffer mechanism includes a spherical groove, which is located at the center of the top of the base. A spherical block is movably connected inside the spherical groove, and a support base is fixedly connected to the top of the spherical block. Several sets of buffer columns are fixedly connected to the top of the base outside the spherical groove, and are arranged in a ring array. The buffer columns are used to press against the bottom of the support base.

[0006] As a further description of the above technical solution: a piston rod is slidably connected to the inner wall of the buffer column, a support plate is fixedly connected to the top of the piston rod, and a spring is fixedly connected between the inner wall of the buffer column and the piston rod.

[0007] As a further description of the above technical solution: the top of the support plate is provided with a displacement groove, and the bottom of the support base is fixedly connected with a number of sliding columns, which are slidably connected in the displacement grooves at corresponding positions.

[0008] As a further description of the above technical solution: the bottom of the sliding column is hemispherical, the inner wall of the displacement groove is arc-shaped, and the sliding column and the displacement groove cooperate with each other.

[0009] As a further description of the above technical solution: a number of limiting posts are fixedly connected to the top of the base, and the positions of the limiting posts and the buffer posts correspond one-to-one.

[0010] As a further description of the above technical solution: the inner wall of the limiting post is provided with a channel, and a connecting pipe is fixedly connected to the buffer post, the connecting pipe being used to connect the interior of the buffer post and the channel.

[0011] As a further description of the above technical solution: a piston hole is provided at one end of the inner wall of the limiting column at the top of the channel, the piston hole faces the outer wall of the support seat, a piston column is slidably connected to the inner wall of the piston hole, an arc-shaped push block is fixedly connected to one end of the piston column facing the outer wall of the support seat, and a rubber pad is fixedly connected to the side of the arc-shaped push block near the support seat.

[0012] As a further description of the above technical solution: the base is threaded with several bolts, the top of the support seat is provided with a connecting groove, and the support seat is provided with several flange holes located outside the connecting groove.

[0013] This utility model has the following beneficial effects: I. In this utility model, the spherical groove and the spherical block cooperate to enable the support seat to have a certain range of shaking adjustment capability. This can not only adapt to the small angular deviation during the installation of prefabricated components and reduce the construction accuracy requirements, but also relieve some stress by small-amplitude deflection of the support seat when encountering external impact, thus avoiding component damage caused by rigid connection.

[0014] II. In this utility model, a hydraulic linkage structure consisting of a buffer column, connecting pipe, channel and piston hole is used. When the support seat tilts, the piston rod on the sinking side will squeeze the medium inside the buffer column. Through hydraulic transmission, the piston column will be pushed out, so that the arc-shaped push block will press against the outer wall of the support seat, realizing automatic limit of the tilt range and avoiding excessive deflection that affects the structural stability. At the same time, the rubber pad on the arc-shaped push block can increase the contact friction and buffer the impact force during the limit, further protecting the components.

Detailed Implementation

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] Reference Figure 2 , Figure 3 , Figure 4 This utility model provides an embodiment of a prefabricated building connection base, including a base 1. A buffer mechanism is provided on the top of the base 1. The buffer mechanism includes a spherical groove 12, which is located at the center of the top of the base 1. A spherical block 23 is movably connected within the spherical groove 12. A support seat 2 is fixedly connected to the top of the spherical block 23. By movably connecting the spherical block 23 within the spherical groove 12 of the base 1, the support seat 2 on the spherical block 23 has a certain range of swaying space. Several sets of buffer columns 13 are fixedly connected to the top of the base 1 outside the spherical groove 12, arranged in a circular array. The buffer columns 13 are used to press against the bottom of the support seat 2. A piston rod 131 is slidably connected to the inner wall of the buffer column 13. A support plate 132 is fixedly connected to the top of the piston rod 131. The inner wall of the buffer column 13 is flush with the bottom of the support seat 2. A spring 134 is fixedly connected between the piston rods 131. A displacement groove 133 is provided on the top of the support plate 132. Several sliding columns 24 are fixedly connected to the bottom of the support seat 2, and the sliding columns 24 are slidably connected in the displacement grooves 133 at the corresponding positions. The bottom of the sliding column 24 is set as a hemispherical surface, and the inner wall of the displacement groove 133 is set as an arc surface. The sliding column 24 cooperates with the displacement groove 133. When the support seat 2 is subjected to external force and it tilts, the piston rod 131 in the tilting direction will push against the sliding column 24 at the bottom of the support seat 2. The tension of the spring 134 pushes the piston rod 131 to support the sliding column 24 so that the support seat 2 can maintain stability as much as possible. When the tilting force is too large, it can overcome the tension of the spring 134, so that the support seat 2 can tilt slightly to relieve the force and avoid damage to the connected parts caused by rigid compression.

[0019] Reference Figure 2 , Figure 3 , Figure 4Several limiting posts 14 are fixedly connected to the top of the base 1, and the positions of the limiting posts 14 and the buffer posts 13 correspond one-to-one. The inner wall of the limiting post 14 has a channel 141. A connecting pipe 142 is fixedly connected to the buffer post 13. The connecting pipe 142 is used to connect the inside of the buffer post 13 and the channel 141. A piston hole 15 is opened at the top end of the inner wall of the limiting post 14 at the top of the channel 141. The piston hole 15 faces the outer wall of the support base 2. A piston post 151 is slidably connected to the inner wall of the piston hole 15. An arc-shaped push block 152 is fixedly connected to one end of the support base 2 facing the outer wall. A rubber pad is fixedly connected to the side of the arc-shaped push block 152 near the support base 2. When the support base 2 overcomes the tension of the spring 134 and tilts slightly, the sinking piston rod 131 will squeeze the medium in the buffer column 13 into the piston hole 15 through the connecting pipe 142 and the channel 141, pushing the piston column 151 out, so that the arc-shaped push block 152 abuts against the support base 2, so as to prevent the support base 2 from tilting too much and affecting the stability of the overall structure.

[0020] Reference Figure 1 The base 1 is threaded with several bolts 11 to fix the base 1 in a designated position. The top of the support 2 is provided with a connecting groove 21 for inserting the steel structure column. The support 2 is provided with several flange holes 22 outside the connecting groove 21 for fixing the connecting column.

[0021] Working principle: In use, the base is first fixed in the designated installation position by bolts 11 on the base 1. Then, the steel structure column of the prefabricated building is inserted into the connecting groove 21 on the top of the support base 2. The column and the support base 2 are fixedly connected by fasteners using flange holes 22. When the building is subjected to external impact or vibration, the spherical block 23 at the bottom of the support base 2 can rotate flexibly in the spherical groove 12 of the base 1, realizing a small-amplitude angle adjustment of the support base 2. At the same time, the sliding column 24 at the bottom of the support base 2 will slide in the displacement groove 133 of the corresponding support plate 132. The sliding column 24 in the tilting direction will squeeze the piston rod 131, causing the piston rod 131 to slide down the inner wall of the buffer column 13 and compress the spring 134. The elastic tension of the spring 134 will form a reverse support force, buffering the vibration energy and preventing the support base 2 from tilting excessively. If the support base 2 tilts significantly, the descending piston rod 131 will force the liquid in the buffer column 13 through the connecting pipe 142 into the channel 141 of the limiting column 14, and then through the channel 141 into the piston hole 15, pushing the piston column 151 to extend towards the support base 2. This ensures that the rubber pad on the arc-shaped push block 152 tightly presses against the outer wall of the support base 2, limiting the maximum tilt of the support base 2 and ensuring the stability of the connection structure. When the external load disappears, the elastic restoring force of the spring 134 will push the piston rod 131 back to its original position, the medium in the buffer column 13 will flow back, the piston column 151 will drive the arc-shaped push block 152 to retract, and the support base 2 will return to its initial horizontal state, achieving the automatic reset function. The entire process, through the synergistic effect of mechanical buffering and hydraulic limiting, ensures both the robustness of the connection and good buffering adjustment capability, effectively improving the impact resistance of the connection parts of prefabricated buildings.

[0022] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
