Description

Technical Field

[0001] This application relates to the field of grouting, and in particular to a prefabricated column grouting device. Background Technology

[0002] Prefabricated columns are the core prefabricated vertical load-bearing components in the field of prefabricated buildings. They refer to column components that are prefabricated in the factory in part or all of the main structure, transported to the site, and assembled using standardized assembly processes.

[0003] During the grouting construction of prefabricated columns, grout needs to be injected into the cavity of the grouting device. When the vent on the grouting device is blocked by splashed grout, the cavity cannot be properly vented, which can easily cause structural defects in the prefabricated column and reduce the production quality of the prefabricated column. Summary of the Invention

[0004] To improve the production quality of prefabricated columns, this application provides a grouting device for prefabricated columns.

[0005] This application provides a prefabricated column grouting device, which adopts the following technical solution: A prefabricated column grouting device includes a base, a positioning cylinder, a grouting cover, and an exhaust assembly. The base has a positioning ring cavity on its surface for the end of the positioning cylinder to be embedded. The inner cavity of the positioning cylinder is for grout to be statically formed. The end face of the positioning cylinder away from the base in the axial direction has an installation cavity for the grouting cover to be embedded. The surface of the grouting cover is connected to a grouting pipe, which communicates with the inner cavity of the positioning cylinder. Grout enters the inner cavity of the positioning cylinder through the grouting pipe. The surface of the grouting cover has multiple exhaust ports spaced apart, and the inner cavity of the positioning cylinder is connected to the multiple exhaust ports. The exhaust assembly includes an exhaust plate and multiple exhaust columns. The exhaust plate is slidably connected to the surface of the grouting cover. The multiple exhaust columns are spaced apart on the surface of the exhaust plate facing the exhaust ports. Each exhaust column corresponds to an exhaust port. When the exhaust plate slides towards the grouting cover, the end of each exhaust column passes through an exhaust port, and the outer circumference of the exhaust column abuts against the inner wall of the exhaust port.

[0006] By adopting the above technical solution, one end of the positioning cylinder along the axial direction is embedded in the positioning ring cavity, and the outer circumferential surface of the positioning cylinder abuts against the inner wall of the positioning ring cavity to form a seal, realizing a detachable connection between the positioning cylinder and the base. The grouting cover is embedded in the installation cavity, and the outer circumferential surface of the grouting cover abuts against the inner wall of the installation cavity to form a seal, realizing a detachable connection between the grouting cover and the positioning cylinder. The grout is injected into the inner cavity of the positioning cylinder through the grouting pipe. The grout settles and forms in the inner cavity of the positioning cylinder. The air in the positioning cylinder is discharged through the exhaust port. When the exhaust plate is driven to slide towards the grouting cover, the exhaust column corresponds to the exhaust port and passes through it. The outer circumferential surface of the exhaust column abuts against the inner wall of the exhaust port and pushes the grout away from the exhaust port and flows back into the inner cavity of the positioning cylinder, reducing material consumption and thus embodying the concept of green technology. It also makes the exhaust port less likely to be blocked by splashed grout, ensuring the stability of the air in the positioning cylinder being discharged from the exhaust port, improving the structural integrity of the prefabricated column, and thus improving the production quality of the prefabricated column.

[0007] Optionally, the exhaust column has a vent hole coaxially formed on the end face facing the exhaust port, the vent hole passing through both sides of the exhaust column axis, and the exhaust plate has a plurality of connecting holes corresponding to the surface of the exhaust column, the connecting holes corresponding to and connecting with the vent holes.

[0008] By adopting the above technical solution, when the outer circumferential surface of the exhaust column presses against the inner wall of the exhaust port to form a seal, the air in the inner cavity of the positioning cylinder can be discharged through the vent hole from the connecting hole, thereby achieving stable discharge of air from the inner cavity of the positioning cylinder and ensuring that air holes are not easily left on the surface of the assembled column, thus improving the production quality of the assembled column.

[0009] Optionally, the grouting cover includes a cover portion and a support portion. One side of the cover portion can be embedded in the mounting cavity, and the other side of the cover portion is connected to the end face of the support portion. The vent is located on the surface of the cover portion, and the vent plate is slidably connected to the surface of the support portion. The venting assembly also includes an venting cylinder and multiple through-posts. The venting cylinder is connected to the surface of the support portion, and the piston rod end of the venting cylinder passes through the surface of the support portion and is connected to the surface of the vent plate. Multiple through-posts are spaced apart on the surface of the support portion facing the vent plate. Each through-post corresponds to a connecting hole, and the end of each through-post can pass through the connecting hole and be embedded in the vent hole.

[0010] By adopting the above technical solution, when the piston rod of the exhaust cylinder extends, the exhaust plate approaches the cover, the exhaust column corresponds to and is embedded in the exhaust port, and the outer circumferential surface of the exhaust column presses against the inner wall of the exhaust port. At the same time, the air in the positioning cylinder is discharged from the connecting hole through the vent hole. When the piston rod of the exhaust cylinder retracts, the exhaust plate moves away from the cover, the through column corresponds to the connecting hole, the end of the through column passes through the connecting hole and is embedded in the vent hole, the outer circumferential surface of the through column presses against the inner wall of the vent hole, and the through column pushes the slurry remaining on the inner wall of the vent hole away from the vent hole, thereby achieving directional cleaning of the exhaust column.

[0011] Optionally, the support portion has multiple air inlets spaced apart on the surface away from the through column. Each air inlet corresponds to one through column. The bottom wall of each air inlet has a cleaning ring hole that penetrates the surface of the support portion and surrounds the outer circumference of the through column.

[0012] By adopting the above technical solution, air is forced to exit through the air inlet and the cleaning ring hole. The cleaning ring hole surrounds the outer circumference of the through column, and the air impacts the outer circumference of the through column and carries away the impurities on the outer circumference of the through column, thereby cleaning the through column.

[0013] Optionally, the support is connected to an air supply assembly, which includes an air supply bladder, an air supply plate, and an air supply rod. The air supply bladder is connected to the surface of the support facing the air inlet, and the inner cavity of the air supply bladder communicates with multiple air inlets. The air supply plate is connected to the surface of the air supply bladder away from the support. One end of the air supply rod is connected to the surface of the air supply plate, and the other end of the air supply rod is connected to the surface of the exhaust plate.

[0014] By adopting the above technical solution, when the exhaust plate slides towards the cover and the end of the exhaust column is embedded in the exhaust port, the air supply rod receives the power of the exhaust plate and drives the air supply plate to slide towards the support. The surface of the support and the surface of the air supply plate squeeze both sides of the air supply bladder, pushing the air in the air supply bladder through the air inlet and cleaning ring hole and impacting the outer circumference of the through column, thereby achieving self-cleaning of the outer circumference of the through column. There is no need to install an external air pump to impact the outer circumference of the through column, reducing the cost of using the grouting device.

[0015] Optionally, the air supply assembly further includes multiple one-way valves and multiple one-way valves. The air supply plate surface is provided with multiple air replenishment holes spaced apart. The inner cavity of the air supply bladder is connected to the multiple air replenishment holes. The one-way valves correspond to and are connected to the air replenishment holes one by one. The one-way valves allow outside air to enter the inner cavity of the air supply bladder through the air replenishment holes. The one-way valves correspond to and are connected to the air inlets one by one. The one-way valves allow air from the inner cavity of the air supply bladder to enter the cleaning ring hole through the air inlets.

[0016] By adopting the above technical solution, when the air supply plate is close to the support part, the surface of the support part and the surface of the air supply plate simultaneously squeeze both sides of the air supply bladder, pushing the air in the air supply bladder through the one-way valve 2, the air inlet and the cleaning ring hole and impacting the outer circumference of the through column; when the air supply plate is far away from the support part, the pressure of the air supply plate and the support part on the air supply bladder disappears, the air supply bladder recovers by its own elasticity, the air pressure in the air supply bladder cavity decreases, and the outside air enters the air supply bladder cavity through the one-way valve 1 and the air replenishment port, realizing the automatic replenishment of air in the air supply bladder cavity.

[0017] Optionally, the seat is connected to a lifting assembly, which includes a lifting cylinder, a connecting rod, and a connecting ring. The lifting cylinder is connected to the surface of the seat, and the piston rod axis of the lifting cylinder is parallel to the axis of the positioning cylinder. One end of the connecting rod is connected to the piston rod surface of the lifting cylinder, and the other end of the connecting rod is connected to the surface of the connecting ring. The inner wall of the connecting ring is coaxially connected to the outer circumferential surface of the positioning cylinder. When the piston rod of the lifting cylinder extends, the connecting rod drives the positioning cylinder away from the seat through the connecting ring.

[0018] By adopting the above technical solution, when the slurry in the positioning cylinder is statically molded to form an assembled column, the surface of the seat facing the inner cavity of the positioning cylinder abuts against the assembled column to form support. The piston rod of the lifting cylinder extends, and the connecting rod drives the positioning cylinder away from the seat through the connecting ring, realizing the demolding of the assembled column in the inner cavity of the positioning cylinder. The assembled column on the seat is removed, the piston rod of the lifting cylinder retracts, and the connecting rod drives the positioning cylinder closer to the seat through the connecting ring. One end of the positioning cylinder in the axial direction is embedded in the positioning ring cavity, and the inner wall of the positioning ring cavity abuts against the outer circumferential surface of the positioning cylinder to form a seal. The slurry is injected into the positioning cylinder through the grouting pipe. The above actions are repeated to improve the processing efficiency of the assembled column.

[0019] Optionally, the base is connected to a feeding assembly, which includes a feeding seat, a push block, and a feeding cylinder. The feeding seat is connected to the surface of the base, and the feeding cylinder is connected to the surface of the feeding seat. The piston rod axis of the feeding cylinder and the positioning cylinder axis are perpendicular to each other. The end of the piston rod of the feeding cylinder passes through the surface of the feeding seat and is connected to the surface of the push block. The surface of the push block facing away from the feeding cylinder faces the positioning cylinder. When the positioning cylinder moves away from the base, the column abuts against the surface of the base, the piston rod of the feeding cylinder extends, and the surface of the push block abuts against the surface of the column and pushes the column away from the positioning ring cavity.

[0020] By adopting the above technical solution, when the slurry in the positioning cylinder is allowed to settle and form a column, the positioning cylinder is driven to slide away from the base along its own axis. The column is separated from the inner cavity of the positioning cylinder. At the same time, the piston rod of the feeding cylinder extends, the surface of the push block abuts against the surface of the column and pushes the column away from the positioning ring cavity, thereby realizing the automatic feeding of the column.

[0021] Optionally, the surface of the push block facing the positioning cylinder is provided with a guide arc surface, the axis of the guide arc surface is oriented towards the axis of the positioning cylinder, and the guide arc surface can fit the outer peripheral surface of the cylinder and push the cylinder away from the positioning ring cavity.

[0022] By adopting the above technical solution, when the piston rod of the feeding cylinder extends, the guide arc surface fits against the outer circumference of the column and pushes the column away from the positioning ring cavity, making it less likely for the column to deviate during the sliding process and improving the stability of the column movement.

[0023] Optionally, the feeding assembly further includes at least two synchronous pulleys and a synchronous belt used in conjunction with the synchronous pulleys. The at least two synchronous pulleys are rotatably connected to the surface of the base at intervals. The synchronous belt is tensioned and connected to the two synchronous pulleys. The surface of the synchronous belt is flush with the surface of the base. The synchronous belt is located on the side of the positioning ring cavity away from the feeding cylinder, and the surface of the synchronous belt is used for placing the column and driving the column away from the positioning ring cavity.

[0024] By adopting the above technical solution, the synchronous belt tensions and connects the two synchronous pulleys. When the piston rod of the unloading cylinder extends, the guide arc surface abuts against the outer circumference of the column and pushes the column away from the positioning ring cavity and against the surface of the synchronous belt. The two synchronous pulleys rotate, and the synchronous belt drives the column to unload the material. No workers are required to move it, which further improves the processing efficiency of the assembled column.

[0025] In summary, this application includes at least one of the following beneficial technical effects: The exhaust plate and exhaust column are designed so that the exhaust column corresponds to the exhaust port and passes through it. The outer circumference of the exhaust column presses against the inner wall of the exhaust port and pushes the slurry out of the exhaust port and flows back into the inner cavity of the positioning cylinder, reducing material consumption and thus embodying the concept of green technology. It also makes the exhaust port less likely to be blocked by splashed slurry, ensuring the stability of the air in the positioning cylinder as it is discharged from the exhaust port, improving the structural integrity of the prefabricated column, and thus improving the production quality of the prefabricated column. The vent holes allow for the stable discharge of air from the positioning cylinder, ensuring that air holes are not easily left on the surface of the assembled column, thereby improving the production quality of the assembled column. The exhaust cylinder and the through column are designed so that the through column pushes the slurry remaining on the inner wall of the vent hole away from the vent hole, thereby achieving directional cleaning of the exhaust column.

[0032] The following is in conjunction with the appendix Figure 1-5 This application will be described in further detail.

[0033] This application discloses a prefabricated column grouting device. (Refer to...) Figure 1 The prefabricated column grouting device includes a base 1, a positioning cylinder 2, a grouting cover 3, and an exhaust component 4. The bottom of the base 1 is fixed to the ground. The end face of the base 1 is provided with a positioning ring cavity 11 for the end of the positioning cylinder 2 to be inserted. The axis of the positioning ring cavity 11 is parallel to the height direction of the base 1. The inner wall of the positioning ring cavity 11 is pressed against the outer circumference of the positioning cylinder 2 to form a seal. The axis of the positioning cylinder 2 is parallel to the height direction of the base 1. Grout is supplied to the inner cavity of the positioning cylinder 2 and allowed to stand and form a prefabricated column.

[0034] Reference Figure 2 and Figure 3 The grouting cover 3 includes a cover part 31 and a support part 32. The support part 32 is integrally formed and fixed on the surface of the cover part 31. The end face of the positioning cylinder 2 away from the seat body 1 in the axial direction is coaxially provided with an installation cavity 21 for the cover part 31 to be inserted. The inner wall of the installation cavity 21 is pressed against the outer peripheral surface of the cover part 31 to form a seal. The support part 32 is located on the side of the cover part 31 away from the positioning cylinder 2, so as to realize the detachable installation of the grouting cover 3 and the positioning cylinder 2.

[0035] Reference Figure 2 and Figure 3The surface of the cover 31 is connected to a grouting pipe 5, which connects to the inner cavity of the positioning cylinder 2. Grout enters the inner cavity of the positioning cylinder 2 through the grouting pipe 5. Multiple vents 311 are spaced apart on the surface of the cover 31. The vents 311 penetrate both sides of the cover 31 in the thickness direction and connect to the inner cavity of the positioning cylinder 2. The venting assembly 4 is connected to the support 32 and can clean the grout in the vents 311. The venting assembly 4 includes an venting cylinder 41, an venting plate 42, multiple through columns 43 and multiple venting columns 44. The venting plate 42 is slidably connected to the surface of the support 32 facing the vents 311. The sliding direction of the venting plate 42 is parallel to the height direction of the seat 1. The surface of the venting plate 42 is provided with a groove 421 for the support 32 to pass through. The surface of the support 32 abuts against the inner wall of the groove 421 and guides the venting plate 42 to slide, making the venting plate 42 less prone to displacement, thereby improving the stability of the venting plate 42 sliding.

[0036] Reference Figure 3 and Figure 4 The exhaust cylinder 41 is bolted to the surface of the support 32 away from the cover 31. The piston rod axis of the exhaust cylinder 41 is parallel to the height direction of the seat 1. The end of the piston rod of the exhaust cylinder 41 passes through the surface of the support 32 and is connected to the surface of the exhaust plate 42. Multiple exhaust columns 44 are spaced apart on the surface of the exhaust plate 42 facing the exhaust port 311. The exhaust port 311 corresponds to the exhaust column 44 one by one. The end of the exhaust column 44 can be embedded in the exhaust port 311, and the outer peripheral surface of the exhaust column 44 can abut against the exhaust port 311. The inner wall of the exhaust port 311 is sealed. The exhaust column 44 is coaxially provided with a vent hole 441 facing the end face of the exhaust port 311. The vent hole 441 passes through both ends of the exhaust column 44 along its own axis. The surface of the exhaust plate 42 away from the exhaust column 44 is provided with a plurality of connecting holes 422. The axis of the connecting holes 422 is parallel to the height direction of the base 1. The connecting holes 422 pass through both sides of the exhaust plate 42 along their own axis. The connecting holes 422 correspond to and are connected to the vent holes 441.

[0037] Reference Figure 3 and Figure 4 Multiple through-posts 43 are spaced apart on the surface of the support 32 facing the exhaust plate 42. The axis of the through-post 43 is parallel to the height direction of the base 1. The through-post 43 corresponds one-to-one with the connecting hole 422. The end of the through-post 43 can pass through the connecting hole 422 and be embedded in the vent hole 441. The outer peripheral surface of the through-post 43 abuts against the inner wall of the vent hole 441 to form a seal.

[0038] Reference Figure 3 and Figure 4When the piston rod of the exhaust cylinder 41 extends, it pushes the exhaust plate 42 close to the cover 31. The exhaust column 44 corresponds to and is embedded in the exhaust port 311. The outer circumferential surface of the exhaust column 44 presses against the inner wall of the exhaust port 311 to form a seal, and pushes the slurry splashed in the exhaust port 311 to flow back to the inner cavity of the positioning cylinder 2 along the surface of the cover 31. The air in the positioning cylinder 2 is discharged from the connecting hole 422 through the vent hole 441. When the piston rod of the exhaust cylinder 41 retracts, it pushes the exhaust plate 42 away from the cover 31. The exhaust column 44 disengages from the exhaust port 311. The through column 43 corresponds to the connecting hole 422. The end of the through column 43 passes through the connecting hole 422 and is embedded in the vent hole 441. The outer circumferential surface of the through column 43 presses against the inner wall of the vent hole 441 to form a seal, and drives the impurities on the inner wall of the vent hole 441 to detach from the vent hole 441, thereby achieving directional cleaning of the inner wall of the vent hole 441.

[0039] Reference Figure 3 and Figure 4 The support part 32 has multiple air inlets 321 spaced apart on the surface away from the through column 43. Each air inlet 321 corresponds to one through column 43. The axis of the air inlet 321 is parallel to the height direction of the base 1. A cleaning ring hole 322 is formed on the bottom wall of the air inlet 321. The cleaning ring hole 322 penetrates the surface of the support part 32 in the direction close to the through column 43. The axis of the cleaning ring hole 322 coincides with the axis of the through column 43, and the cleaning ring hole 322 surrounds the outer circumferential surface of the through column 43. The airflow can pass through the air inlet 321 and the cleaning ring hole 322 and impact the outer circumferential surface of the through column 43, carrying away impurities on the outer circumferential surface of the through column 43, thereby achieving self-cleaning of the through column 43.

[0040] Reference Figure 4 and Figure 5 The support part 32 is equipped with an air supply component 6, which can push airflow into the air inlet 321. The air supply component 6 includes an air supply bladder 61, an air supply plate 62, an air supply rod 63, multiple one-way valves 64 and multiple one-way valves 65. The air supply bladder 61 can be made of rubber or silicone. In this embodiment, the air supply bladder 61 is made of rubber and has a certain deformation capability. The air supply bladder 61 is connected to the surface of the support part 32 facing the air inlet 321. The inner cavity of the air supply bladder 61 is connected to multiple air inlets 321. The one-way valves 65 correspond to and are connected to the air inlets 321 one by one. The one-way valves 65 allow air from the inner cavity of the air supply bladder 61 to enter the cleaning ring hole 322 through the air inlet 321.

[0041] Reference Figure 4 and Figure 5The air supply plate 62 is connected to the surface of the air supply bag 61 facing away from the support part 32. The number of air supply rods 63 can be one, two, or more. In this embodiment, there are multiple air supply rods 63. The ends of the multiple air supply rods 63 are connected at intervals to the surface of the air supply plate 62 facing the air supply bag 61. Multiple clearance cavities are spaced apart on the surface of the air supply bag 61, through which the air supply rods 63 pass. Clearance grooves are provided on the surface of the support part 32 facing the clearance cavities, penetrating both sides of the support part 32. The ends of the air supply rod 63 that are away from the air supply plate 62 are respectively provided with relief cavities and relief grooves and connected to the surface of the exhaust plate 42. The surface of the air supply plate 62 is provided with multiple air replenishment holes 621 at intervals. The axis of the air replenishment hole 621 is parallel to the height direction of the base. The air replenishment hole 621 passes through both sides of the air supply plate 62 along its own axis. The inner cavity of the air supply bag 61 is connected to the multiple air replenishment holes 621. The one-way valve 64 corresponds to and is connected to the air replenishment holes 621. The one-way valve 64 allows outside air to enter the inner cavity of the air supply bag 61 through the air replenishment holes 621.

[0042] Reference Figure 4 and Figure 5 When the exhaust plate 42 approaches the cover 31, the air supply rod 63 receives the power from the exhaust plate 42 and pushes the air supply plate 62 closer to the support 32. The surface of the support 32 and the surface of the air supply plate 62 press against both sides of the air supply bladder 61. The air in the air supply bladder 61 passes through the one-way valve 65, the air inlet 321 and the cleaning ring hole 322 and impacts the outer circumferential surface of the penetrating column 43, carrying away impurities from the outer circumferential surface of the penetrating column 43. When the exhaust plate 42 moves away from the cover 31, the air supply rod 63 receives the power from the exhaust plate 42 and pushes the air supply plate 62 away from the support 32. The pressure of the support 32 and the air supply plate 62 on the air supply bladder 61 disappears, and the air supply bladder 61 rebounds by its own elasticity. The air pressure in the inner cavity of the air supply bladder 61 decreases, and outside air enters the inner cavity of the air supply bladder 61 through the one-way valve 64 and the air replenishment hole 621, realizing automatic replenishment of air in the air supply bladder 61.

[0043] Reference Figure 1 and Figure 2 The base 1 is equipped with a lifting assembly 7, which can drive the positioning cylinder 2 to rise and fall. The lifting assembly 7 includes a lifting cylinder 71, a connecting rod 72, and a connecting ring 73. The lifting cylinder 71 is fixed to the surface of the base 1 by bolts. The piston rod axis of the lifting cylinder 71 is parallel to the height direction of the base 1. One end of the connecting rod 72 is connected to the piston rod surface of the lifting cylinder 71, and the other end of the connecting rod 72 is connected to the surface of the connecting ring 73. The inner ring wall of the connecting ring 73 is coaxially connected to the outer circumference of the positioning cylinder 2. When the piston rod of the lifting cylinder 71 extends, the connecting rod 72 drives the positioning cylinder 2 to slide away from the base 1 along its own axis through the connecting ring 73. The end of the positioning cylinder 2 disengages from the positioning ring cavity 11, and the base 1 abuts against the surface of the assembled column to form support, thereby realizing the demolding of the assembled column in the inner cavity of the positioning cylinder 2.

[0044] Reference Figure 1 and Figure 2 The base 1 is equipped with a feeding assembly 8, which can push the assembled column away from the positioning ring cavity 11 for feeding. The feeding assembly 8 includes a feeding seat 81, a push block 82, a feeding cylinder 83, two synchronous pulleys 84, and a synchronous belt 85 used in conjunction with the synchronous pulleys 84. The feeding seat 81 is welded and fixed to the surface of the base 1. In this embodiment, there are multiple feeding cylinders 83, which are divided into multiple groups. Multiple groups of feeding cylinders 83 are spaced apart and connected to the surface of the feeding seat 81. The arrangement direction of the multiple groups of feeding cylinders 83 is parallel to the height direction of the base 1. Multiple feeding cylinders 83 in the same group are spaced apart and connected to the surface of the feeding seat 81. The arrangement direction of the multiple feeding cylinders 83 in the same group is parallel to the width direction of the base 1, and the piston rod axis of the feeding cylinder 83 is parallel to the length direction of the base 1.

[0045] Reference Figure 1 and Figure 2 In this embodiment, there are multiple push blocks 82. Each push block 82 corresponds to one of the groups of feeding cylinders 83. The piston rod surfaces of the multiple feeding cylinders 83 in the same group are connected at intervals to the surface of the push block 82. The surface of the push block 82 facing the positioning cylinder 2 is provided with a guide arc surface 821. The axis of the guide arc surface 821 is oriented toward the axis of the positioning cylinder 2. The guide arc surface 821 can fit against the outer peripheral surface of the assembled column to form a limit.

[0046] Reference Figure 1 and Figure 2 The surface of the seat 1 is provided with a rotating cavity 12 for the synchronous wheel 84 to rotate. The rotating cavity 12 is located on the side of the positioning ring cavity 11 away from the material feeding seat 81. Two synchronous wheels 84 are rotatably connected to the inner wall of the rotating cavity 12 at intervals. The axis of the synchronous wheel 84 is parallel to the width direction of the seat 1. The synchronous belt 85 is tensioned to connect the two synchronous wheels 84. The surface of the synchronous belt 85 is flush with the surface of the seat 1, and the surface of the synchronous belt 85 is used for the assembly column to be placed and to drive the column away from the positioning ring cavity 11.

[0047] Reference Figure 1 and Figure 2 When the slurry in the positioning cylinder 2 settles and forms a column, the positioning cylinder 2 is driven to slide away from the base 1 along its own axis. The column is separated from the inner cavity of the positioning cylinder 2, the piston rod of the unloading cylinder 83 extends, the guide arc surface 821 abuts against the outer circumference of the column and pushes the column away from the positioning ring cavity 11 and abuts against the surface of the synchronous belt 85. The two synchronous wheels 84 rotate, and the synchronous belt 85 drives the column to unload. No workers need to move it, which further improves the processing efficiency of the assembled column.

[0048] The implementation principle of the prefabricated column grouting device in this application embodiment is as follows: One end of the positioning cylinder 2 along the axial direction is embedded in the positioning ring cavity 11, and the outer peripheral surface of the positioning cylinder 2 abuts against the inner wall of the positioning ring cavity 11 to form a seal, thereby realizing the detachable connection between the positioning cylinder 2 and the base 1. The grouting cover 3 is embedded in the installation cavity 21, and the outer peripheral surface of the grouting cover 3 abuts against the inner wall of the installation cavity 21 to form a seal, thereby realizing the detachable connection between the grouting cover 3 and the positioning cylinder 2. Grout is injected into the inner cavity of the positioning cylinder 2 through the grouting pipe 5. The grout settles and forms in the inner cavity of the positioning cylinder 2. The air in the positioning cylinder 2 is discharged through the exhaust port 311, and the piston of the exhaust cylinder 41 is activated. The rod extends, pushing the exhaust plate 42 close to the cover 31. The exhaust column 44 corresponds to and is embedded in the exhaust port 311. The outer circumference of the exhaust column 44 presses against the inner wall of the exhaust port 311 and pushes the slurry out of the exhaust port 311 and flows back into the inner cavity of the positioning cylinder 2. The air in the positioning cylinder 2 is discharged from the connecting hole 422 through the vent hole 441, reducing material consumption and thus embodying the concept of green. It also makes the exhaust port 311 less likely to be blocked by splashed slurry, ensuring the stability of the air in the positioning cylinder 2 being discharged from the exhaust port 311, improving the structural integrity of the prefabricated column, and thus improving the production quality of the prefabricated column.

[0049] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
