Description

Technical Field

[0001] The invention relates to the technical field of prefabricated column connection structures, in particular to a prefabricated column with an assembled embedded base. Background Art

[0002] In the construction industry, prefabricated columns of prefabricated embedded bases are widely used due to their advantages such as fast construction speed and strong quality controllability. Existing prefabricated columns of prefabricated embedded bases usually adopt steel bar insertion connection, that is, the steel bars of the upper prefabricated column are inserted into the reserved sockets of the lower prefabricated column, and then fixed connection is achieved by grouting or other methods. This connection method improves the construction efficiency to a certain extent, but in the actual operation process, there are still some obvious defects: First, the existing prefabricated columns of the prefabricated embedded base often lack effective cleaning measures for the mud and dust on the top of the steel bars and the lower prefabricated columns before connection. Due to the complex construction site environment, a large amount of mud, dust and other impurities are easily attached to the top of the steel bars and the lower prefabricated columns. If these impurities are not cleaned in time during the connection process, it will seriously affect the fit between the upper prefabricated column and the lower prefabricated column, thereby reducing the connection quality. The presence of impurities may also cause gaps in the connection part, affecting the overall stability and durability of the structure; Secondly, the existing connection methods often lack automated cleaning and vibration processing mechanisms during the connection process. Construction workers usually need to manually clean impurities on the top of the steel bars and the lower prefabricated columns, which not only increases the difficulty and cost of construction, but may also lead to incomplete cleaning and affect the connection quality. At the same time, the existing connection methods also lack effective cleaning methods for impurities in the sockets, such as gravel, etc. These impurities can easily have an adverse effect on the connection of the prefabricated columns and reduce the stability and reliability of the structure. Summary of the invention

[0003] In view of the deficiencies in the prior art, the present invention provides a prefabricated column with an assembled embedded base, which solves the technical problems mentioned in the background technology.

[0004] To achieve the above purpose, the present invention is implemented by the following technical solutions: a prefabricated column of an assembled embedded base, comprising a lower prefabricated column and an upper prefabricated column, a socket adapted to the steel bar is provided at the bottom of the upper prefabricated column, and a connecting component is provided between the lower prefabricated column and the upper prefabricated column; The connecting component includes a fixed frame located on the outside of the lower prefabricated column and the upper prefabricated column, and the first sliding plate and the second sliding plate are respectively connected to the two sides of the fixed frame for transverse sliding.

[0007] As a further preferred embodiment of the present technical solution, the fixed frame includes a U-shaped frame and a connecting plate, and clamping rods are symmetrically arranged at both ends of the first movable plate. Second clamping grooves are opened on both sides of the U-shaped frame and at the ends opposite to the clamping rods. Push blocks are arranged at the upper and lower ends of the second clamping grooves. The outer end of the push block is fixedly connected to a control rod slidably installed on the U-shaped frame, and a tension spring mounted on the control rod is arranged between the push block and the inner wall of the second clamping groove.

[0008] As a further optimization of the present technical solution, ventilation grooves are opened on both sides of the fixed frame, and positioning shafts are rotatably connected on both sides and the middle position of the ventilation grooves, and blades are arranged on the positioning shafts. The top of the positioning shaft in the middle position is fixedly connected to the bottom of the driving shaft, and a large pulley is fixedly connected to the positioning shaft, and small pulleys are fixedly connected to the top of the positioning shafts on both sides, and the large pulley is connected to the two small pulleys through belt transmission.

[0009] As a further optimization of the present technical solution, a fixed plate and a plurality of support plates are fixedly connected on both sides of the inner wall of the fixed frame, and a second bevel gear and a disc are rotatably connected to the support plate through a rotating shaft.

[0011] Compared with the prior art, it has the following beneficial effects: The sand and dust on the top of the steel bars and the lower precast columns are cleaned by a roller brush, ensuring the fit of the upper and lower precast columns and avoiding the influence of impurities on the connection quality. This cleaning method effectively improves the connection quality between the two, thereby enhancing the overall stability and durability of the structure. The connection surface after cleaning is clean and free of impurities, making the connection between the precast columns more firm and reliable, which helps to reduce the risk of structural deformation or collapse caused by unstable connections and further improves the safety of the entire structure. The cleaning work makes the connection between the precast columns smoother and reduces the resistance and difficulty during the construction process. Construction workers can more easily align and fix the upper and lower precast columns, thereby improving construction efficiency. In addition, the automated cleaning device also reduces the time and cost of manual cleaning. The stability and accuracy of the roller brush during the cleaning process are ensured through precise limit and sliding mechanisms. This design not only improves the cleaning effect, but also ensures the controllability and consistency of construction quality.

[0012] By designing a detachable U-shaped frame and connecting plate, construction workers can complete the connection and disassembly work between prefabricated columns more conveniently. This design greatly simplifies the operation process, saves time, and significantly improves the efficiency of the entire construction process; the detachable design allows the U-shaped frame and connecting plate to be reused according to actual construction needs, reducing material costs. At the same time, when the components are damaged or worn, only the damaged components need to be replaced without disassembling the entire prefabricated column structure, reducing maintenance costs; the same U-shaped frame and connecting plate can be used to connect multiple prefabricated columns, improving the flexibility and economy of construction. This design allows the construction team to flexibly adjust the construction plan according to actual needs and adapt to different construction environments and conditions; the detachable design not only facilitates construction operations, but also helps to ensure construction quality. Through precise limit and sliding mechanisms, a stable connection between the connecting plate and the U-shaped frame is ensured, thereby improving the connection quality between prefabricated columns; when the U-shaped frame or connecting plate is damaged, construction workers can easily remove and replace it without disassembling the entire prefabricated column structure. This convenience of maintenance ensures the continued reliability of the connection and reduces the difficulty and cost of maintenance.

[0013] Through the linkage mechanism of gears, drive shafts and positioning shafts, the blades are able to rotate and generate airflow, which effectively blows away the dust on the upper surface of the lower prefabricated column and significantly reduces the accumulation of dust. This design not only keeps the construction environment clean, but also helps to improve the connection quality between prefabricated columns. The rotation of the drive shaft also drives the synchronous rotation of the bevel gear and the arc-shaped tilting block. Through a series of mechanical transmissions and the elastic force of the spring, the knocking rod performs knocking and vibration treatment on the upper prefabricated column. This process effectively cleans the impurities in the jack, such as gravel, and avoids the adverse effects of these impurities on the connection of the prefabricated columns. This design ensures the stability and reliability of the connection between the prefabricated columns. The above cleaning and vibration treatment processes are all automated and do not require manual intervention, which greatly improves the construction efficiency. Construction workers can focus more on other key steps, such as aligning and fixing prefabricated columns, thereby speeding up the entire construction process. By cleaning dust and impurities, the clean and tight connection between the prefabricated columns is ensured. This clean connection helps to enhance the overall stability of the structure and improve the seismic and wind resistance of the prefabricated assembled structure. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0016] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the drawings of the specification. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0017] Embodiment 1: Combination Figure 1-Figure 9 As shown, the present invention provides a technical solution: a prefabricated column of an assembled embedded base, comprising a lower prefabricated column 1 and an upper prefabricated column 2, the top of the lower prefabricated column 1 is fixedly connected by a steel bar 11, and the bottom of the upper prefabricated column 2 is provided with a socket 21 adapted to the steel bar 11, a rectangular groove 12 is provided on one side of the lower prefabricated column 1, a rectangular block 13 is provided in the rectangular groove 12, a first clamping groove 17 is provided on one side of the rectangular block 13, and a positioning rod 14 is fixedly connected to the inner cavity of the rectangular block 13, a tilting block 15 is slidably connected to the positioning rod 14, and the tilting block 15 can be slidably installed on the rectangular block 13, and in order to ensure the stability of the positioning rod 14, a first damping spring 16 is sleeved on its outer wall; A guide block 22 is provided on one side of the upper precast column 2, and a sliding groove 23 is provided on the surface of the guide block 22. A connecting assembly 3 is provided between the lower precast column 1 and the upper precast column 2. The connecting assembly 3 includes a fixed frame 31 located outside the lower precast column 1 and the upper precast column 2. The two sides of the fixed frame 31 are respectively connected with a first sliding plate 32 and a second sliding plate 33 for transverse sliding. The inner end of the second sliding plate 33 is fixedly connected with a row of long rods 312, and the other end of the long rod 312 is provided with a roller brush 313 for cleaning the steel bar 11 and the top of the lower precast column 1. The inner ends of the first sliding plate 32 are fixedly connected with an inner tooth plate 310, and the inner ends of the second sliding plate 33 are fixedly connected with an outer tooth plate 311. A driving shaft 321 rotatably mounted on the fixed frame 31 is provided between the outer tooth plate 311 and the inner tooth plate 310. The driving shaft 321 is fixedly connected with a gear 322 that meshes with the outer tooth plate 311 and the inner tooth plate 310 on both sides. When the upper prefabricated column 2 drives the first sliding plate 32 to move outward on the fixed frame 31 and compresses the second damping spring 39, it can also drive the fixed frame 31 to move downward, so that the roller brush 313 moves downward from the top position of the steel bar 11, and the first sliding plate 32 moves outward to drive the inner tooth plates 310 on both sides to move outward, so that the inner tooth plates 310 drive the meshing gears 322 to rotate, and the rotating gears 322 drive the meshing outer tooth plates 311 to move outward, so that the outer tooth plates 311 drive the second sliding plate 33 to move outward. The fixing frame 31 moves outward on the fixing frame 31, so that the fixing frame 31 drives the long rod 312 and the roller brush 313 to move outward, that is, the roller brush 313 can also move outward synchronously while moving downward from the top position of the steel bar 11, so that the roller brush 313 cleans the sand and dust on the top of the steel bar 11 and the lower prefabricated column 1 in this process. Such a design ensures that the surface contact between the upper prefabricated column 2 and the lower prefabricated column 1 is more consistent, thereby not affecting the connection between the upper prefabricated column 2 and the lower prefabricated column 1, and improving the stability and reliability of the overall structure; In the present invention, a second damping spring 39 is specially designed on the outer part of the first sliding plate 32, and the other end of the second damping spring 39 is firmly fixedly connected to the inner wall of the fixed frame 31. The inner end of the first sliding plate 32 is fixedly connected to a fixed shaft 34. The upper end of the second sliding plate 33 is rotatably connected to the first movable plate 35 and the second movable plate 37. The other end of the first movable plate 35 is rotatably connected to a mounting seat 36, and the mounting seat 36 can perfectly match the sliding groove 23. A limiting rod 38 is provided at the other end of the second movable plate 37, and the limiting rod 38 can match the first clamping groove 17. In practical applications, when the upper prefabricated column 2 is connected to the lower prefabricated column 1, the limiting rod 38 at one end of the second movable plate 37 needs to be installed in the first slot 17, so that the limiting rod 38 will push the tilting block 15 to be located on the positioning rod 14 and move inward, thereby compressing the first damping spring 16. When the limiting rod 38 moves to the bottom of the first slot 17, the limiting rod 38 is no longer in contact with the tilting block 15. At this time, the tilting block 15 will move outward under the elastic force of the positioning rod 14, forming a blocking effect on the limiting rod 38, thereby completing the limiting process of one end of the second movable plate 37; Next, it is necessary to slide the mounting seat 36 into the sliding groove 23, and seal the top of the sliding groove 23 to prevent the mounting seat 36 from sliding out of the sliding groove 23. When the upper prefabricated column 2 drives the guide block 22 to move downward, the fixed frame 31 will also move downward. Since one end of the second movable plate 37 has been limited, the guide block 22 pushes the first movable plate 35 to move outward through the mounting seat 36. In this way, the first movable plate 35 cooperates with the fixed shaft 34 to push the first sliding plate 32 located on the fixed frame 31 to move outward and compress the second damping spring 39. At the same time, when the first sliding plate 32 moves outward, it will drive the inner tooth plates 310 on both sides to move outward.

[0018] In the embodiment of the present invention, when the upper precast column 2 is connected to the lower precast column 1, the bottom plug hole 21 of the upper precast column 2 is precisely aligned with and connected to the steel bar 11. Then, the limiting rod 38 at one end of the second movable plate 37 is installed in the first slot 17 to ensure that the limiting rod 38 can push the tilting block 15 to move inward along the positioning rod 14 and compress the first damping spring 16. When the limiting rod 38 moves to the bottom of the first slot 17, the limiting rod 38 no longer contacts the tilting block 15. At this time, the tilting block 15 moves outward under the elastic force of the positioning rod 14, thereby forming a blocking effect on the limiting rod 38. In this way, the limiting process of the end of one side of the second movable plate 37 is completed. Subsequently, the mounting seat 36 is slidably inserted into the sliding slot 23, and the top of the sliding slot 23 is sealed to prevent the mounting seat 36 from sliding out of the sliding slot 23. When the upper precast column 2 drives the guide block 22 to move downward, the fixed frame 31 will also move downward accordingly, which makes the roller brush 313 move downward from the top position of the steel bar 11. Since one end of the second movable plate 37 has been limited, the guide block 22 pushes the first movable plate 35 to move outward through the mounting seat 36. The first movable plate 35 pushes the first sliding plate 32 on the fixed frame 31 to move outward with the cooperation of the fixed shaft 34 and compresses the second damping spring 39. When the first sliding plate 32 moves outward, the inner tooth plates 310 on both sides will also move outward accordingly, thereby making the inner tooth plates 310 drive the gears 322 meshing therewith to rotate, and the rotation of the gears 322 drives the outer tooth plates 311 meshing therewith to move outward, thereby making The outer tooth plate 311 drives the second sliding plate 33 located on the fixed frame 31 to move outward, so that the fixed frame 31 drives the long rod 312 and the roller brush 313 to move outward, so that the roller brush 313 can move outward to the outer position of the lower precast column 1 while moving downward from the top position of the steel bar 11. In this process, the roller brush 313 cleans the sand and dust on the top of the steel bar 11 and the lower precast column 1, ensuring that the surface contact between the upper precast column 2 and the lower precast column 1 is more consistent, thereby not affecting the connection between the two. By removing the sand and dust, the contact surface between the upper precast column 2 and the lower precast column 1 is ensured to be clean and free of impurities, thereby improving the connection quality between the two, which helps to enhance the overall stability and durability of the structure. The cleaning work makes the connection between the prefabricated columns smoother, reduces the resistance and difficulty in the construction process, and allows construction workers to more easily align and fix the upper prefabricated column 2 with the lower prefabricated column 1, which not only improves the construction efficiency, but also ensures the construction quality, making the entire structure more stable and reliable.

[0019] Embodiment 2: Combination Figure 7 As shown, based on the first embodiment, the fixing frame 31 is composed of two main parts: a U-shaped frame 314 and a connecting plate 315. The shape of the U-shaped frame 314 is similar to the letter "U", and the connecting plate 315 serves to connect and fix the U-shaped frame 314; At both ends of the first movable plate 35, clamping rods 320 are symmetrically arranged. The function of these clamping rods 320 is to interact with the fixed frame 31 to ensure that the first movable plate 35 can be stably fixed in an appropriate position. Second clamping grooves 316 are provided on both sides of the U-shaped frame 314 and at the ends opposite to the clamping rods 320. These second clamping grooves 316 provide space for the clamping rods 320 to be inserted, thereby realizing the connection between the first movable plate 35 and the fixed frame 31; At the upper and lower ends of the second card slot 316, a push block 318 is provided. The function of the push block 318 is to push the card rod 320 by external force, so as to realize the movement and fixation of the first movable plate 35. The outer end of the push block 318 is fixedly connected with a control rod 317 slidably mounted on the U-shaped frame 314. The sliding function of the control rod 317 enables the push block 318 to move flexibly, thereby controlling the position of the card rod 320. In order to ensure the smooth movement of the pushing block 318 on the inner wall of the second slot 316, a tension spring 319 is specially arranged on the control rod 317. The function of the tension spring 319 is to provide a continuous pulling force to keep the pushing block 318 in the appropriate position. At the same time, it can also easily push the locking rod 320 when needed. Through this design, the connection between the fixed frame 31 and the first movable plate 35 is more stable and flexible.

[0020] In the embodiment of the present invention, a "T"-shaped structure is adopted in the design of the second slot 316. This design enables the clamping rod 320 to be made of elastic material. Under the elastic force of the tension spring 319, the push block 318 can move smoothly outward. When the upper prefabricated column 2 is successfully connected to the lower prefabricated column 1, the installation work of the mounting seat 36 and the limiting rod 38 is also completed. At this time, the position of the U-shaped frame 314 is determined. In this case, the construction personnel can slide the clamping rods 320 on both sides of the connecting plate 315 into the second slot 316, so that the inner wall of the second slot 316 forms an effective limiting blocking effect on the clamping rod 320, ensuring the stability of the connecting plate 315. However, when it is necessary to remove the connecting plate 315, the construction personnel can drive the push block 318 to move inward by pressing the control rod 317 and stretch the tension spring 319. This action enables the push block 318 to push the two clamping rods 320 to move inward, so that the second clamping groove 316 no longer forms a clamping effect on the clamping rod 320. At this time, the construction personnel can easily remove the connecting plate 315 from the U-shaped frame 314, and then remove the U-shaped frame 314 from the upper prefabricated column 2 and the lower prefabricated column 1. Through this repeated operation, the connection work of multiple groups of prefabricated columns can be completed; By designing such a detachable U-shaped frame 314 and connecting plate 315, construction workers can greatly simplify the connection process between prefabricated columns. This design not only saves valuable time, but also significantly improves the efficiency of the entire construction process. The detachable design allows the U-shaped frame 314 and connecting plate 315 to be reused according to actual construction needs, which not only reduces material costs but also increases construction flexibility, because the same parts can be used for the connection of multiple prefabricated columns, thereby improving construction flexibility and economy. In addition, if the U-shaped frame 314 or the connecting plate 315 is damaged or worn during use, the construction workers can easily remove and replace it without disassembling the entire prefabricated column structure. This convenience of maintenance greatly reduces maintenance costs and ensures the continued reliability of the connection. Through this design, the construction team can complete the installation and disassembly of the prefabricated columns more efficiently, thereby improving the overall construction efficiency while ensuring the construction quality.

[0021] Example 3: Combination Figure 8 , Fig. 9 As shown, on the basis of the second embodiment, ventilation slots 323 are provided on both sides of the fixed frame 31, and positioning shafts 325 are installed on both sides and the middle of these ventilation slots 323 by means of rotational connection. A vane 324 is specially provided on the positioning shaft 325 to facilitate the realization of specific functions. The top of the positioning shaft 325 located in the middle is tightly combined with the bottom of the driving shaft 321 by means of fixed connection. In addition, a large pulley 327 is fixedly connected to the positioning shaft 325, and small pulleys 328 are fixedly connected to the top of the positioning shaft 325 at the two sides of the ventilation slot 323. The large pulley 327 is connected to the two small pulleys 328 by belt 329, forming an effective transmission system. On both sides of the inner wall of the fixed frame 31, a fixed plate 335 and a plurality of support plates 331 are fixedly connected respectively. The support plate 331 is rotatably connected with a second bevel gear 332 and a disc 333 matched therewith via a rotating shaft. The surface of the disc 333 is provided with a plurality of arc-shaped tilting blocks 334 in a circular array. These arc-shaped tilting blocks 334 play a key role in the working process. One side of the second bevel gear 332 is meshedly connected with the first bevel gear 330 fixedly mounted on the driving shaft 321, thereby ensuring the accuracy and reliability of the transmission. A knocking rod 336 is slidably connected to the fixed plate 335, and the outer end of the knocking rod 336 is fixedly connected by a linkage plate 337, which ensures the stability and reliability of the knocking rod 336. The inner end of the linkage plate 337 is fixedly connected to a guide rod 338 that is slidably adapted to the arc-shaped tilting block 334, so that the knocking rod 336 can cooperate with the arc-shaped tilting block 334 more accurately during the movement. The outer wall of the knocking rod 336 is fixedly connected to a limiting block 339, and a third damping spring 340 is arranged between the limiting block 339 and the fixed plate 335 and is sleeved on the knocking rod 336. Such a design can effectively control the movement range of the knocking rod 336, reduce unnecessary impact and vibration, and improve the stability and service life of the entire system.

[0022] In the embodiment of the present invention, driven by the gear 322, the driving shaft 321 starts to rotate synchronously. With the rotation of the driving shaft 321, the positioning shaft 325 located in the middle position also rotates synchronously. The positioning shaft 325 further drives the positioning shafts 325 on both sides to rotate synchronously through the large pulley 327 and the small pulley 328 connected thereto, as well as the transmission effect of the belt 329. This linkage mechanism enables the blade 324 to rotate, thereby generating airflow during the rotation process. These airflows effectively blow away the dust on the upper surface of the lower prefabricated column 1, thereby reducing the accumulation of dust. At the same time, during the rotation of the driving shaft 321, the first bevel gear 330 is also driven to rotate synchronously. The first bevel gear 330 cooperates with the second bevel gear 332 meshing on one side, so that the second bevel gear 332 also starts to rotate synchronously. The rotation of the second bevel gear 332 further drives the synchronous rotation of the rotating shaft, the disc 333, and the arc-shaped inclined block 334. During the rotation of the arc-shaped inclined block 334, due to the design of its inclined surface, the guide rod 338 is pushed outward. The movement of the guide rod 338 drives the linkage plate 337, the guide rod 338, and the limit block 334. 39 moves outward together and compresses the third damping spring 340. When the arc-shaped inclined block 334 rotates to no longer contact with the guide rod 338, the elastic force of the third damping spring 340 begins to appear, pushing the knocking rod 336 to move to one side of the upper precast column 2. The movement of the knocking rod 336 knocks and vibrates the upper precast column 2, effectively vibrating and cleaning the impurities in the socket 21 on the upper precast column 2. This process ensures that the socket 21 does not contain impurities such as gravel, thereby avoiding the adverse effects of these impurities on the connection between the upper precast column 2 and the lower precast column 1.
