Description

Technical Field

[0001] The present invention belongs to the technical field of building construction engineering, and particularly relates to an anchoring device for concrete columns in building construction. Background Art

[0002] Reinforced concrete columns are structural members widely used in buildings. In frame structures and frame-shear wall structures, reinforced concrete columns serve as both the main compressive members and lateral force resisting members at the same time. The quality of their compressive bearing capacity and seismic performance has a great impact on the safety of the entire building. Therefore, the anchoring depth of the concrete column needs to meet the actual requirements. In actual applications, the anchoring length of the concrete column also needs to be adjusted according to specific design requirements and on-site conditions. When adjusting, factors such as the strength grade of the concrete, the material and diameter of the steel bars, the design requirements of the structure, and the on-site construction conditions need to be comprehensively considered. In addition, in special cases, such as when bearing large tensile or compressive forces, or being in a corrosive environment, etc., it may be necessary to further adjust the anchoring depth of the concrete column.

[0003] An anchoring device for concrete columns in building construction disclosed in Patent Application No. CN202121177617.2 includes a foundation. An installation block is fixedly installed in the installation groove of the foundation through bolts. A fixing groove is formed in the middle of the upper surface of the installation block. First adjustment grooves are vertically formed in the middle of the front side, rear side, left side, and right side of the fixing groove. Lower-middle parts of the inner walls of the front side, rear side, left side, and right side of the fixing groove are vertically provided with sliding grooves. The first adjustment grooves communicate with the fixing groove through the sliding grooves. Limiting grooves are formed at the four corners of the inner wall of the bottom end of the fixing groove. A push plate is slidably connected to the lower end inside the fixing groove. By combining the installation block, the fixing groove, the push plate, and the positioning pin, when installing a concrete column, the bottom end of the concrete column can be automatically pre-fixed, avoiding the inclination and shaking of the concrete column during the installation process, which affects the subsequent concrete filling and fixing operations. The structure is simple and convenient to operate.

[0004] In the prior art, the concrete column is pre-fixed through the fixing groove and the positioning pin, which can prevent the concrete column from inclining and shaking during the subsequent concrete filling operation, but there are still deficiencies as a whole:

[0005] First of all, according to the "Code for Design of Concrete Structures", it can be known that the anchoring length of the concrete column needs to be appropriately adjusted according to different designed concrete columns. The existing concrete column anchoring devices cannot adjust the adaptability of the anchoring depth, which increases the construction difficulty and there is a certain lack of overall applicability;

[0006] Secondly, when the steel reinforcement cage of the concrete column is anchored and butted, due to the large volume of the steel reinforcement cage, a crane is usually used for hoisting and installation. After the hoisting is completed, when a small amount of position adjustment of the steel reinforcement cage is required, it is difficult to quickly adjust the orientation due to weight, friction, etc. The subsequent angle adjustment of the whole steel reinforcement cage is difficult, which affects the construction efficiency.

[0007] Finally, after the steel reinforcement cage is fixed, grouting needs to be carried out between the steel reinforcement cage and the base. The existing device has a slow concrete pouring speed and cannot carry out rapid pouring at multiple positions. Moreover, the vibration effect of the vibrating rod on the concrete during the concrete pouring process is poor, and there will be a large number of air bubbles and holes in the mixed soil, thus affecting the anchoring strength of the concrete column. Summary of the Invention

[0008] In order to overcome the deficiencies of the prior art, the present invention provides an anchoring device for concrete columns in building construction. Through the setting of structures such as connecting support members, the anchoring depth of the fixed connecting plate and the steel reinforcement cage column inside the circular groove can be adaptively adjusted according to different bending angles of the first bending plate; through the setting of components such as the rotating support plate and the rotating roller, before the fixed connecting plate and the steel reinforcement cage column are placed into the circular groove, the orientation adjustment can be carried out on the outer circumferential surface of multiple rotating rollers, and the rotating characteristics between the rotating support plate and the first slider can also be utilized to effectively prevent the position of the fixed connecting plate and the steel reinforcement cage column from being too high and quickly sliding into the circular groove under the action of its own gravity, resulting in inclined displacement, etc.

[0009] In order to achieve the above object, the present invention provides the following technical solution: an anchoring device for concrete columns in building construction, including a concrete base and a circular groove, the upper end surface of the concrete base is provided with a circular groove, and a steel reinforcement cage column is installed in the circular groove;

[0010] A fixed connecting plate, the fixed connecting plate is slidably arranged inside the circular groove, the upper end surface of the fixed connecting plate is fixedly connected to the lower end surface of the steel reinforcement cage column, and a first through hole is arranged on the end surface of the fixed connecting plate inside the steel reinforcement cage column;

[0011] A connecting column, the connecting column is slidably arranged inside the first through hole, and an elastic support component is fixedly connected to the lower end surface of the connecting column;

[0012] First sliders, a plurality of the first sliders are uniformly slidably arranged on the outer end surface of the circular groove along the circumferential direction;

[0013] A rotating support plate, the rotating support plate is rotatably arranged on the upper end surface of the first slider, and a rotating roller is rotatably arranged inside the rotating support plate;

[0014] The rotating rod is disposed on one side of the first slider in an inclined and oscillating manner. A clamping and limiting block is arranged on the outer part of the rotating rod on the upper end surface of the rotating support plate, and the clamping and limiting block forms clamping and fixing for one end of the rotating support plate.

[0015] Through the settings of structures such as the fixed connecting plate, the first slider, and the roller, the fixed connecting plate and the steel cage column can be conveniently adjusted in orientation before anchoring. When the fixed connecting plate and the steel cage column enter the circular groove subsequently, through the cooperation of structures such as the rotating rod, the first slider, and the rotating support plate, the fixed connecting plate can slowly slide into the interior of the circular groove along the outer circular surface of the roller, effectively preventing the fixed connecting plate and the steel cage column from quickly entering the interior of the circular groove under the action of their own gravity, causing damage to the elastic support assembly arranged at the bottom of the circular groove, thereby affecting the accuracy of the anchoring depth.

[0016] Optionally, the elastic support assembly includes:

[0017] A connecting support member, which is arranged on the lower end surface of the connecting column;

[0018] A first bending plate, and a plurality of the first bending plates are uniformly arranged in a ring on the outer side wall of the connecting support member;

[0019] A first horizontal plate, which is fixedly connected to the lower end surface of the first bending plate, and a connecting hole is arranged on the first horizontal plate.

[0020] Through the settings of structures such as the connecting support member, the first bending plate, and the first horizontal plate, the elastic support assembly can adjust the distance between the connecting support member and the ground in the circular groove by bending the first bending plate according to the actual construction requirements, so that when the fixed connecting plate is fixed on the end surface of the connecting support member, the anchoring depth of the fixed connecting plate and the steel cage column in the circular groove meets the actual needs, avoiding the difficulty in adjusting the anchoring depth of the subsequent steel cage column and improving the construction efficiency.

[0021] Optionally, a plurality of divergently arranged threaded holes are uniformly arranged along the circumferential direction at the bottom of the circular groove, and the plurality of threaded holes and the connecting holes can be connected and fixed by fixing bolts.

[0022] Optionally, a plurality of first chutes are uniformly arranged in a ring on the inner side wall of the circular groove, and the first slider is slidably connected to the first chutes;

[0023] Second chutes, and two of the second chutes are respectively arranged on the two side walls of the first chutes;

[0024] A first protrusion, which is slidably arranged inside the second chute, and each first protrusion is fixedly connected to the side wall of the first slider.

[0025] Through the settings of structures such as the first sliding groove and the first sliding block, the horizontal sliding displacement of the first sliding block and the rotating support plate under the rotation of the rotating rod is stably restricted, thereby improving the stability of the fixed connecting plate and the steel reinforcement cage column sliding into the circular groove.

[0026] Optionally, a damper is rotatably connected between the first sliding block and the rotating support plate.

[0027] Through the setting of the damper, the rotating support plate will not rotate rapidly after being disengaged from the clamping limit of the clamping limit block, avoiding the collision between the lower end surface of the rotating support plate and one end of the first sliding block, thereby preventing the fixed connecting plate and the steel reinforcement cage column on the rotating roller from shaking and tilting due to the position change of the rotating roller, effectively improving the stability of the device.

[0028] Optionally, inclined grooves, a plurality of the inclined grooves are arranged in a circumferential direction in the area between the bottom of the circular groove and the upper end surface of the concrete base;

[0029] First grouting holes, a plurality of the first grouting holes are communicated and arranged on the walls of the circular groove and the inclined grooves.

[0030] Through the settings of the inclined grooves and the first grouting holes, when grouting the inside of the circular groove subsequently, rapid grouting treatment can be carried out inside the first grouting holes through the plurality of inclined grooves and the plurality of first grouting holes, effectively improving the grouting efficiency and saving construction time.

[0031] Optionally, a first rotating connecting piece is rotatably arranged on one side of the first sliding block, and the rotating rod is fixedly connected inside the first connecting piece.

[0032] Optionally, a second sliding block, the second sliding block is slidably arranged at the upper port of the inclined groove, and a push cylinder is rotatably arranged inside the second sliding block;

[0033] A second rotating connecting piece, the second rotating connecting piece is arranged on the outer cylindrical surface of the rotating rod between the first rotating connecting piece and the clamping limit block, and the second rotating connecting piece is rotatably and detachably connected to the output end of the push cylinder.

[0034] Through the settings of the second rotating connecting piece, the push cylinder and the second sliding block and other structures, the output ends of the plurality of push cylinders can drive the plurality of rotating rods to rotate synchronously, so that the horizontal sliding actions of the plurality of first sliding blocks are consistent, thereby increasing the stability when the fixed connecting plate and the steel reinforcement cage column enter the circular groove.

[0035] Optionally, a plurality of second grouting holes are annularly distributed on the end surface of the fixed connecting plate.

[0036] By setting the second grouting hole, the efficiency of concrete grouting inside the circular groove is improved. Moreover, the vibrator can enter the space between the circular groove and the fixed connecting plate through the second grouting hole to vibrate the concrete there, effectively reducing the air bubbles in the concrete between the circular groove and the fixed connecting plate and enhancing the strength of the concrete pouring.

[0037] Optionally, a plurality of abutting plates are arranged on the outer side wall of each of the first bending plates.

[0038] By setting the plurality of abutting plates, not only the clamping strength between the elastic support assembly and the concrete is increased, but also the fixing strength of the elastic support assembly to the fixed connecting plate and the steel reinforcement cage column is further increased, and at the same time, the anchoring strength of the concrete column is increased.

[0039] In summary, compared with the prior art, the beneficial effects of this solution are as follows:

[0040] (1) Through the settings of structures such as the connecting support member, the threaded hole, and the first bending plate in the present invention, the anchoring depth of the fixed connecting plate and the steel reinforcement cage column inside the circular groove can be adaptively adjusted according to the different bending angles of the first bending plate. While increasing the adaptability of the device, components such as the connecting support member and the connecting column can further fix the fixed connecting plate, forming a tension on the bottom of the fixed connecting plate, playing the role of a reinforcing rib, improving the overall strength of the concrete column. Moreover, by utilizing the elastic characteristics of components such as the first bending plate and the abutting plate, when vibrating the concrete inside the circular groove subsequently, this characteristic can be utilized to increase the vibration treatment of the concrete inside the circular groove by the vibrator, increasing the strength of the concrete inside the circular groove and effectively improving the strength of the entire concrete column;

[0041] (2) Through the settings of components such as the first slider, the rotating support plate, and the rotating roller in the present invention, before the fixed connecting plate and the steel reinforcement cage column are placed inside the circular groove, the azimuth adjustment can be carried out by rotating on the outer circumferential surfaces of the plurality of rotating rollers, reducing the labor intensity of workers. At the same time, by utilizing the rotating characteristics between the rotating support plate and the first slider, by pulling the first slider, the fixed connecting plate can slowly slide along the outer circumferential surfaces of the plurality of inclined rotating rollers into the circular groove, effectively preventing the fixed connecting plate and the steel reinforcement cage column from being too high in position and quickly sliding into the circular groove under the action of their own gravity and colliding with the connecting support member, reducing the deformation of the elastic support assembly, thereby ensuring the anchoring depth of the fixed connecting plate and the steel reinforcement cage column and the accuracy of the azimuth of the fixed connecting plate and the steel reinforcement cage column, and effectively improving the stability and anchoring accuracy of the device;

[0042] (3) Through the arrangement of structures such as the inclined chute, the first grouting hole, and the second grouting hole, the present invention enables multi-directional concrete grouting operations when grouting the concrete inside the circular groove. Moreover, when pouring the concrete, the first grouting hole located above inside the inclined chute can also play a role in exhausting air, increasing the concrete pouring efficiency inside the circular groove while reducing the content of concrete bubbles inside the circular groove, effectively improving the strength of concrete construction.

Detailed implementation mode

[0056] In order to enable the personnel in the technical field to better understand the solution of the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0057] Embodiment 1:

[0058] As Figure 1 、 Figure 2 and Figure 3 shown, an anchoring device for a concrete column in building construction, a circular groove 11 is provided on the upper end surface of the concrete base 10, a fixed connecting plate 12 is slidably arranged inside the circular groove 11, a steel reinforcement cage column 13 is fixedly arranged on the upper end surface of the fixed connecting plate 12, a plurality of second grouting holes 39 are arranged in a ring shape on the end surface of the fixed connecting plate 12 outside the steel reinforcement cage column 13, a first through hole 16 is arranged on the end surface of the fixed connecting plate 12 inside the steel reinforcement cage column 13, and a connecting column 15 is slidably arranged inside the first through hole 16.

[0059] Specifically, the concrete base 10 is integrally cast in advance, and then placed according to the specific casting position of the concrete column to make preparations in advance for the anchoring of the subsequent concrete column. The woven steel reinforcement cage column 13 needs to be fixed on the end surface of the fixed connecting plate 12 before pouring. The fixed connecting plate 12 is inserted into the circular groove 11 and fixed to the circular groove 11 to form the anchoring of the steel reinforcement cage column 13. The plurality of second grouting holes 39 are all concrete pouring ports, and the gap between the fixed connecting plate 12 and the circular groove 11 can be filled with concrete through the second grouting holes 39. Moreover, after the concrete in the circular groove 11 is poured, the concrete in the second grouting holes 39 forms further fixation of the fixed connecting plate 12 with the concrete at the upper and lower ends of the fixed connecting plate 12, while reducing the weight of the fixed connecting plate 12 and enhancing the fixation of the concrete in the circular groove 11 to the fixed connecting plate 12.

[0060] Furthermore, as Figure 3, Figure 8 , Figure 10 and Figure 11 As shown in Figure 8 , Figure 10 and Figure 11 , an elastic support assembly is fixedly connected to the lower end surface of the circular groove 11. The elastic support assembly includes a connection support member 14 disposed on the lower end surface of the connection column 15. A plurality of first bending plates 41 are uniformly arranged in a ring shape on the outer side of the connection support member 14. A plurality of abutting plates 37 are arranged on the outer side wall of each first bending plate 41. A first cross plate 42 is connected to the lower end of each first bending plate 41. A connection hole 38 is arranged on each first cross plate 42. A plurality of threaded holes 17 diverging in a circumferential direction are uniformly arranged on the inner bottom surface of the circular groove 11. A fixing bolt 18 is threadedly connected inside the threaded hole 17.

[0061] Specifically, before installing the fixed connection plate 12 into the circular groove 11, the distance between the connection support member 14 and the inner bottom surface of the circular groove 11 can be adjusted according to the parameter data of the steel cage column 13 until the distance between the connection support member 14 and the inner bottom surface of the circular groove 11 meets the length requirement for the steel cage column 13 to be anchored in the concrete base 10. The distance between the connection support member 14 and the inner bottom surface of the circular groove 11 can be changed by bending a plurality of first bending plates 41 to change the angle between the first bending plates 41 and the connection support member 14, thereby changing the distance between the connection support member 14 and the inner bottom surface of the circular groove 11. Then, through the threaded cooperation of the fixing bolt 18 and the threaded hole 17, the first cross plate 42 is fixed at the upper port of the corresponding threaded hole 17.

[0062] When the fixed connection plate 12 is installed into the circular groove 11, the connection column 15 on the connection support member 14 will first insert into the first through hole 16 on the fixed connection plate 12. Through the cooperation of the external nut, the connection column 15 and the connection support member 14, the fixed connection plate 12 is fixed on the upper end surface of the connection support member 14. At this time, the connection column 15 can not only fix the fixed connection plate 12 and the steel cage column 13, but also has a central positioning function for the fixed connection plate 12 and the steel cage column 13.

[0063] Through the arrangement of the connection support member 14, the first bending plates 41 and the first cross plates 42, not only the bottom support for the fixed connection plate 12 and the steel cage column 13 is formed, which can prevent the steel cage column 13 from tilting during the subsequent concrete pouring process, but also a tensile and buffering effect on the steel cage column 13 can be formed inside the concrete after pouring, playing the role of a reinforcing bar, effectively improving the strength of the entire concrete building.

[0064] A plurality of abutting plates 37 are arranged in a stepped manner. After pouring concrete inside the circular groove 11, the abutting plates 37 can increase the connection firmness between the elastic support assembly and the concrete inside the concrete, enhancing the strength of the entire concrete column. Moreover, during the concrete pouring process, the vibrator can extend through the second grouting hole 39 into the space between the fixed connecting plate 12 and the circular groove 11 to vibrate the concrete inside the circular groove 11. At this time, the vibrator can abut against the abutting plate 37, enabling the vibrator to drive the abutting plate 37 and the entire elastic support assembly to vibrate. While increasing the vibration effect of the vibrator on the concrete, it can also perform abutting vibration on different levels of the abutting plates 37 according to the stepped abutting plates 37, thereby driving the concrete on different levels to vibrate layer by layer, effectively increasing the pouring strength of the concrete inside the circular groove 11 and improving the overall strength of the entire concrete column.

[0065] Furthermore, as Figure 3 shown, a plurality of inclined grooves 19 are evenly arranged in a ring shape on the outer side of the concrete base 10, and a plurality of first grouting holes 20 are arranged on the inner side wall of each inclined groove 19.

[0066] Specifically, the first grouting holes 20 are arranged in a vertical direction in sequence. When pouring concrete inside the circular groove 11 after the subsequent fixation of the fixed connecting plate 12 and the steel reinforcement cage column 13 is completed, the concrete can be directly poured into the plurality of inclined grooves 19, and then the concrete flows into the circular groove 11 through the first grouting holes 20 until the circular groove 11 and the inclined grooves 19 are filled with concrete, completing the pouring between the fixed connecting plate 12, the steel reinforcement cage column 13 and the concrete base 10.

[0067] When the concrete slurry is poured into the circular groove 11 through the second grouting hole 39, it can also enter the space between the circular groove 11 and the fixed connecting plate 12 through the inclined grooves 19 and the first grouting holes 20, improving the pouring efficiency and thus enhancing the overall efficiency of the construction project.

[0068] Furthermore, as Figure 4 , Figure 5 , Figure 6 , Figure 7 and Figure 9As shown in the figure, a first chute 21 is provided on the end face of the concrete base 10 at the upper port of each inclined chute 19. A first slider 23 is slidably arranged inside the first chute 21. A second chute 22 is provided on the inner side wall of the first chute 21. A first protrusion 24 is slidably arranged inside the second chute 22. The first protrusion 24 is fixedly connected to the side wall of the first slider 23. A first rotating connector 28 is rotatably arranged on one side of the first slider 23. A rotating rod 29 is arranged inside the first rotating connector 28. A rotating support plate 25 is rotatably arranged above the first slider 23. A roller 26 is rotatably arranged inside the rotating support plate 25. A clamping limit block 30 is arranged on the upper end face of the rotating support plate 25 outside the rotating rod 29. The clamping limit block 30 forms a limit clamping for the rotating support plate 25.

[0069] Specifically, the overall length of the rotating support plate 25 is longer than the length of the first slider 23. When the fixed connecting plate 12 and the steel cage column 13 are hoisted into the circular groove 11 by external equipment, first, the first through hole 16 provided on the inner bottom surface of the circular groove 11 is inserted into the first through hole 16 provided on the fixed connecting plate 12. At this time, the first through hole 16 forms a central positioning for the fixed connecting plate 12. At the same time, it is necessary to rotate the rotating rod 29 so that the rotating rod 29 drives the clamping limit block 30 to rotate along the rotating connection between the first rotating connector 28 and the first slider 23 until the clamping limit block 30 forms a limit clamping for the upper end face of the rotating support plate 25. Then, continue to lower the fixed connecting plate 12 and the steel cage column 13 until the lower bottom surface of the fixed connecting plate 12 abuts against the outer circumferential surface of the plurality of rollers 26. At this time, the fixed connecting plate 12 and the steel cage column 13 can be rotated according to the specific placement orientation of the fixed connecting plate 12 and the steel cage column 13. The plurality of rollers 26 form a rolling support for the bottom of the fixed connecting plate 12, making the rotation of the fixed connecting plate 12 and the steel cage column 13 more convenient and labor-saving.

[0070] When the first slider 23 and the first protrusion 24 are installed inside the first chute 21 and the second chute 22, they need to be adjusted according to the diameter of the fixed connecting plate 12 so that when the lower end face of the fixed connecting plate 12 abuts against the outer circumferential surface of the roller 26, the part of the outer circumferential surface of the roller 26 that supports the lower end face of the fixed connecting plate 12 is the part between the rotating connection point of the rotating support plate 25 and the first slider 23 and the circular groove 11, which is convenient for the subsequent sliding of the fixed connecting plate 12 along the outer circumferential surface of the roller 26 into the circular groove 11.

[0071] After the orientation adjustment of the fixed connecting plate 12 and the steel cage column 13 is completed, the multiple rotating rods 29 are rotated synchronously, so that the rotating rods 29 drive the clamping limit blocks 30 to disengage the limit clamping connection with the rotating support plate 25. At this time, since the downward pressing part of the outer circumferential surface of the rotating roller 26 by the fixed connecting plate 12 is located between the rotating connection point of the rotating support plate 25 and the first sliding block 23 and the circular groove 11, the rotating support plate 25 will drive the rotating roller 26 to tilt until the lower end surface of the rotating support plate 25 abuts against the edge of the upper end surface of the first sliding block 23. Since the overall length of the rotating support plate 25 is longer than the length of the first sliding block 23, the inclination angle between the rotating support plate 25 and the rotating roller 26 and the first sliding block 23 is larger, so that The fixed connecting plate 12 slides down the roller 26 for a longer distance. At this time, a plurality of inclined rollers 26 form a support for the edge of the lower end surface of the fixed connecting plate 12. Each rotating rod 29 is rotated slowly and synchronously, so that one end of the bottom of the rotating rod 29 abuts against the inner wall of the inclined groove 19. The connection between the first rotating connecting member 28 and the rotating rod 29 is used as a stretching point, and the rotating rod 29 and the inner wall of the inclined groove 19 are used as support points. The first slider 23 is driven to slowly disengage from the first sliding groove 21 by using the lever principle. During this process, the first protrusion 24 and the roller 26 follow the first slider 23 to move outward in a synchronous diffusion shape, and the fixed connecting plate 12 slides along the outer cylindrical surface of the roller 26 and slowly moves downward until it is completely disengaged from the outer cylindrical surface of the roller 26.

[0072] The above process enables the fixed connecting plate 12 to slowly move to the inside of the circular groove 11 within a certain distance, effectively preventing the fixed connecting plate 12 from moving to the inside of the circular groove 11 too quickly after adjusting its position, thereby ensuring the accuracy of the position of the steel cage column 13 and avoiding problems in subsequent construction. At the same time, it also prevents the distance between the fixed connecting plate 12 and the steel cage column 13 and the elastic support component from being too high, so that the kinetic energy generated by the falling of the fixed connecting plate 12 and the steel cage column 13 causes deformation of the elastic support component, thereby affecting the anchoring depth of the fixed connecting plate 12 and the steel cage column 13.

[0073] The first sliding block 23, the rotating support plate 25, the rotating rod 29 and other components are all detachably arranged, so that these parts are not only easy to install and disassemble, but also can be repeatedly used multiple times, effectively reducing the construction cost.

[0074] Embodiment 2:

[0075] Based on the first embodiment, a further embodiment is made, such as Figure 4 , Figure 5 and Figure 6As shown in the figure, an anchoring device for a concrete column in building construction. A third chute 34 is provided on the end face of the concrete base 10 at the upper port of each inclined chute 19. A second slider 33 is slidably arranged inside the third chute 34. A fourth chute 35 is provided on the inner side wall of the third chute 34. A second protrusion 36 is slidably arranged inside the fourth chute 35. The second protrusion 36 is fixedly connected to the side wall of the second slider 33. A push cylinder 32 is rotatably arranged inside the second slider 33. A second rotating connector 31 is arranged on the outer cylindrical surface of the rotating rod 29 between the first rotating connector 28 and the clamping limit block 30. The second rotating connector 31 is rotatably and detachably connected to the output end of the push cylinder 32.

[0076] Specifically, the push cylinder 32 is a common electric push cylinder, a hydraulic push cylinder, etc., which is prior art and will not be elaborated in this solution. The output end of the push cylinder 32 drives the second rotating connector 31 to pull the rotating rod 29 to rotate along the rotating connection between the first rotating connector 28 and the first slider 23, so that multiple rotating rods 29 can be synchronously rotated and stretched under the control of the same power switch or hydraulic switch, enabling multiple first sliders 23 to move synchronously. Furthermore, the sliding of the lower end face of the fixed connecting plate 12 on the outer cylindrical surface of multiple rollers 26 is more synchronous, effectively increasing the movement stability when the fixed connecting plate 12 enters the circular groove 11, thereby improving the accuracy of the orientation of the steel cage column 13.

[0077] Moreover, the second rotating connector 31 and the push cylinder 32 are rotatably connected by bolts, and the second slider 33 and the second protrusion 36 are respectively slidably arranged inside the third chute 34 and the fourth chute 35, making the entire assembly easy to install and disassemble, and capable of being reused multiple times, effectively saving the construction cost.

[0078] Embodiment Three:

[0079] On the basis of Embodiment One or Two, a further embodiment is made, such as Figure 12 As shown in the figure, an anchoring device for a concrete column in building construction. The elastic support assembly further includes a second bending plate 43 and a second cross plate 44 arranged between the connecting support 14 and multiple first bending plates 41. A second bending plate 43 is provided on one side of each first bending plate 41, and a second cross plate 44 is provided between each second bending plate 43 and the first bending plate 41.

[0080] Specifically, the addition of the second bending plate 43 and the second horizontal plate 44 enables the entire elastic support assembly to adjust the distance between the connecting support member 14 and the inner bottom surface of the circular groove 11. Not only can the distance between the connecting support member 14 and the circular groove 11 be adjusted by bending the first bending plate 41, but also the distance between the connecting support member 14 and the circular groove 11 can be adjusted by bending the second bending plate 43. Moreover, the first bending plate 41 and the second bending plate 43 can be bent simultaneously to adjust the distance between the connecting support member 14 and the circular groove 11, improving the adjustment accuracy of the distance between the circular groove 11 and the connecting support member 14 by the elastic support assembly and increasing the adjustment range of the distance between the circular groove 11 and the connecting support member 14 by the entire elastic support assembly.

[0081] Embodiment 4:

[0082] Based on Embodiments 1 to 3, a further embodiment is provided. As Figure 5 shown, in an anchoring device for a concrete column in building construction, a damper 27 is provided between the first slider 23 and the rotating support plate 25. Connecting grooves 40 are provided on the upper end surface of the first slider 23 and the lower end surface of the rotating support plate 25, and both ends of the damper 27 are rotatably connected to the inside of the connecting grooves 40 on the first slider 23 and the rotating support plate 25 respectively.

[0083] Specifically, the damper 27 is a common damper, which is prior art and will not be elaborated in detail in this solution. After the clamping limit block 30 disengages from the limit clamping of the rotating support plate 25, one end of the rotating support plate 25 will be pressed down by the self-weight of the fixed connecting plate 12 and the steel reinforcement cage column 13, causing the rotating support plate 25 to rotate rapidly, so that one end of the rotating support plate 25 collides with one end of the first slider 23, resulting in the displacement of the positions of the fixed connecting plate 12 and the steel reinforcement cage column 13. The setting of the damper 27 can form a stretch on one end of the rotating support plate 25, slowing down the rotation speed of the rotating support plate 25 and the roller 26, thereby improving the stability when the fixed connecting plate 12 and the steel reinforcement cage column 13 slide into the circular groove 11.
