Description

Technical Field

[0001] This application relates to the technical field of structural column construction, and in particular to a formwork for casting at the top of a structural column. Background Technology

[0002] In the construction of infill walls in building buildings, structural columns are important secondary structural components in masonry construction.

[0003] Traditional construction methods for structural columns typically involve pouring concrete after the infill wall has reached a certain height or the top brickwork is completed. This process requires multiple steps, including formwork making, formwork erection, concrete pouring, curing, and formwork removal, resulting in high labor costs, extensive use of formwork, and a long construction period. The high consumption of formwork materials and labor leads to low economic efficiency, and the repeated use and disposal of formwork is also environmentally unfriendly. Furthermore, the practice of "pouring first, then chiseling" at the top of the structural column causes material waste and generates construction debris, with significant labor costs for chiseling. Additionally, prolonged periods of working at height with hands suspended in the air pose safety hazards for workers.

[0004] Currently, U-shaped blocks are typically used as permanent formwork for structural columns, forming a unified structural column structure with concrete. This eliminates the need for traditional formwork erection and the cumbersome process of repairing tie rod holes later. However, existing formwork for pouring concrete at the top of structural columns cannot adequately address the problems caused by the trough-shaped opening at the top, indicating significant room for improvement. Summary of the Invention

[0005] This application provides a casting formwork for the top of a structural column, which can greatly reduce the chiseling work at the top of the column, ensure the casting quality at the top of the structural column, and reduce the waste of concrete materials.

[0006] This application provides a casting formwork for the top of a structural column, employing the following technical solution:

[0007] A casting formwork for the top of a structural column includes a base, a casting hopper, a baffle, a guide plate, and a slide rail. The base has a casting opening. The casting hopper is connected to the base and located on one side of the casting opening. The casting hopper has a casting groove communicating with the casting opening. The slide rail is mounted on the base. The baffle is slidably connected to the slide rail. The casting hopper has a clearance opening for the baffle to slide through, communicating with the casting groove. The portion of the baffle located in the casting groove can cover the casting opening. The guide plate is located in the casting groove. One end of the guide plate is rotatably connected to the casting hopper. The rotation axis of the guide plate is perpendicular to the sliding direction of the baffle, and the other end of the guide plate abuts against the end of the baffle closest to the casting groove.

[0008] By adopting the above technical solution, during the process of casting the structural column using the top casting formwork, the concrete first enters the casting trough through the casting hopper, and then enters the casting space through the casting opening along the guide plate. When the concrete fills the casting space to the casting opening, as the concrete continues to be poured, the control baffle slides to gradually cover the casting opening. The guide plate will also rotate with the sliding of the baffle, changing the position of the concrete through the casting opening. This can reduce the amount of concrete in the casting space overflowing into the casting trough through the casting opening, thereby effectively avoiding the formation of a hopper at the top of the structural column, greatly reducing the need for chiseling at the hopper, ensuring the casting quality of the top of the structural column, and reducing the waste caused by the formation of a hopper or overflow into the casting trough.

[0009] Optionally, it also includes a driving component, which is rotatably connected to the slide rail. The driving component has a gear structure, and the slide rail has a rack structure. The gear structure meshes with the rack structure, and the rotation of the driving component drives the baffle to slide.

[0010] By adopting the above technical solution, the meshing of the gear structure and the rack structure controls the sliding of the baffle, which makes it easier for construction personnel to control the sliding of the baffle and improves the control accuracy of the baffle sliding. This makes it easier for construction personnel to control the sliding of the baffle according to the concrete pouring speed.

[0011] Optionally, the baffle has a plurality of first leakage ports at one end near the guide plate, and when the first leakage ports are located in the pouring trough, both ends are connected to the pouring trough and the pouring port, respectively; the pouring hopper has a plurality of second leakage ports at one end near the relief port, and the second leakage ports are connected to the relief port and the pouring trough.

[0012] By adopting the above technical solution, when the concrete level in the pouring space is higher than the baffle, a small amount of concrete will overflow into the pouring trough through the first leakage port, and then flow out of the pouring trough through several second leakage ports along the end face of the baffle. This allows construction personnel to determine in a timely manner whether the baffle needs to be controlled to slide based on whether the concrete has flowed out, thereby reducing the construction difficulty of pouring at the top of the structural column and further reducing the amount of concrete overflowing into the pouring trough.

[0013] Optionally, a cleaning component is also included, which is disposed on the driving component. The cleaning component abuts against the end face of the baffle away from the base. The cleaning component is located on one side of the pouring hopper and close to the clearance opening. The rotation of the driving component drives the cleaning component to rotate.

[0014] By adopting the above technical solution, after the concrete flows out, it will flow along the end face of the baffle to the cleaning component. The concrete remaining on the surface of the cleaning component can reduce the amount of concrete residue on the surface of the baffle, making it easier for the baffle to be reused after cleaning. At the same time, during the process of controlling the sliding of the baffle by rotating the drive component, the rotation of the drive component can drive the cleaning component to rotate, thereby improving the cleaning effect of the cleaning component on the concrete on the surface of the baffle and improving the cleanliness of the surface of the baffle after use.

[0015] Optionally, the end of the baffle away from the casting trough has a receiving part, and the receiving part has a receiving groove with an opening facing the relief port.

[0016] By adopting the above technical solution, when concrete flows down the end face of the baffle and fails to remain on the surface of the cleaning component, the concrete will flow into the receiving trough, making the concrete residue on the baffle surface more concentrated, which is convenient for the baffle to be reused after subsequent cleaning. At the same time, it can reduce the probability of concrete flowing directly to the ground of the construction site, keeping the environment around the construction site clean.

[0017] Optionally, the end of the pouring hopper near the relief opening is rotatably connected to the slide rail, and the rotation axis of the pouring hopper is parallel to the rotation axis of the guide plate.

[0018] By adopting the above technical solution, the baffle is controlled to slide until it completely covers the pouring opening. When the concrete pouring is completed, the pouring bucket is controlled to rotate in a direction away from the base. This makes it convenient for construction workers to clean the concrete left in the pouring trough above the guide plate, thereby improving the cleanliness of the pouring bucket and guide plate after use and facilitating continued use after cleaning.

[0019] Optionally, the guide plate extends outward along its own rotation axis and has a snap-fit ​​part, and the slide rail extends outward in the direction away from the base and has a snap-fit ​​frame. The snap-fit ​​frame has a guide groove and a snap-fit ​​groove. The guide groove is located on the side of the snap-fit ​​groove away from the slide rail. The end of the guide groove near the slide rail communicates with the snap-fit ​​groove, and the end of the guide groove away from the slide rail passes through the snap-fit ​​frame.

[0020] The rotation of the guide plate causes the locking part to rotate. During the rotation of the guide plate, the locking part is adapted to the locking groove. When the guide plate rotates to its limit position away from the clearance opening, the locking part is adapted to the guide groove, and the locking part moves along the guide groove to drive the casting bucket to rotate.

[0021] By adopting the above technical solution, the pouring hopper can only rotate relative to the base when the baffle slides to completely cover the pouring opening, i.e. when the pouring is completed. This can effectively prevent the pouring hopper from rotating due to misoperation or other reasons during the pouring process, and thus effectively prevent concrete from being wasted because it cannot be delivered into the pouring space through the pouring hopper.

[0022] Optionally, the guide plate has a contact portion at one end away from the snap-fit ​​portion. When the baffle slides and drives the guide plate to rotate to its limit position away from the clearance opening, the contact portion is located on the side of the base away from the casting hopper.

[0023] By adopting the above technical solution, when the baffle slides to completely cover the pouring opening, that is, when the pouring is completed, the contact part comes into contact with the concrete at the top of the pouring space. The concrete can push the contact part to exert an outward force on the guide plate. The force can drive the pouring bucket to rotate relative to the base, so that the pouring bucket can rotate automatically and in a timely manner without the need for construction personnel to operate. At the same time, it is convenient for construction personnel to handle the concrete that will flow out after the pouring bucket rotates.

[0024] Optionally, the contact portion has several blocking blocks. When the pouring hopper rotates to its limit position away from the pouring port, the pouring hopper abuts against the receiving portion, the contact portion abuts against the baffle, and the several blocking blocks respectively seal several of the first leakage ports.

[0025] By adopting the above technical solution, both the receiving part and the contact part can restrict the rotation of the pouring hopper, thereby effectively preventing the concrete in the pouring trough from flowing to the construction site ground due to uncontrolled excessive rotation angle during the automatic rotation of the pouring hopper; at the same time, several blocking blocks seal several first leakage outlets, which can prevent the concrete in the pouring space from continuing to overflow through the first leakage outlets, thereby further reducing concrete material waste, improving the surface flatness of the final structural column top after pouring and forming, and reducing the amount of chiseling work.

[0026] Optionally, the baffle has a wedge-shaped surface at one end near the casting groove, and the wedge-shaped surface is located on the side of the baffle away from the base.

[0027] By adopting the above technical solution, the wedge-shaped surface can reduce the resistance of the baffle sliding, making the process of the baffle sliding deeper into the pouring groove more convenient and labor-saving. At the same time, it can make the concrete overflowing from the first seepage port flow down along the wedge-shaped surface through the second seepage port, reducing the probability that the concrete overflowing from the first seepage port will directly remain in the pouring groove.

[0028] In summary, this application includes at least one of the following beneficial effects:

[0029] 1. It can greatly reduce the chiseling work at the top of the trough, improve the surface flatness after the top of the structural column is cast, and thus improve the casting quality of the top of the structural column;

[0030] 2. It can reduce the construction difficulty during the pouring process at the top of the structural column, making it easier for construction personnel to know the pouring status of the concrete and operate the pouring formwork at the top of the structural column according to the pouring status;

[0031] 3. It can reduce the waste of concrete materials and lower the probability of waste concrete materials polluting the construction site;

[0032] 4. It allows construction workers to easily clean up any residual concrete left on the top of the structural column after use, facilitating the reuse of the top formwork. Attached Figure Description

[0039] The following is in conjunction with the appendix Figure 1-5 This application will be described in further detail.

[0040] Reference Figure 1This application discloses a top casting formwork for structural columns, used to assist in the casting and shaping of structural columns. A crossbeam 102 is located above two walls 101 to be filled. A toothed joint 103 is formed below the crossbeam 102 and between the two walls 101. After filling the toothed joint 103 by stacking several U-shaped blocks 104, a casting space 105 for the structural column is formed inside the U-shaped blocks 104. The top casting formwork is fixedly installed on the top of the two walls 101 to be filled, assisting in the pouring of concrete from the top of the casting space 105 into the casting space 105, facilitating the filling of the casting space 105 by the concrete to form the structural column.

[0041] Reference Figure 1 and Figure 2 The top casting formwork for the structural column includes a base 1, a slide rail 2, a casting hopper 3, a baffle 4, and a guide plate 5.

[0042] In this embodiment, the base 1 is preferably a rectangular plate structure. The base 1 is fixedly installed on the top of the wall 101 to be filled, located on one side of the U-shaped block 104 and below the crossbeam 102. The end face of the base 1 is in contact with the two walls 101 to be filled on both sides of the toothed joint 103. The top of the base 1 is provided with a pouring port 11 for concrete to enter the pouring space 105. Preferably, the pouring port 11 is rectangular in shape and communicates with the pouring space 105.

[0043] In this embodiment, the base 1 is preferably fixedly installed on the two walls 101 to be filled by four tie bolts. The four tie bolts pass through the four corners of the base 1 and the two walls 101 to be filled, respectively. Since tie bolts are common prior art in the field, they will not be described in detail here, and are only briefly shown in the accompanying drawings.

[0044] The slide rail 2 is a rectangular structure. The slide rail 2 is fixedly installed on the side of the base 1 away from the wall 101 to be filled. Preferably, two slide rails 2 are fixedly installed on the base 1. The two slide rails 2 are located on both sides of the pouring opening 11, and the slide rails 2 are vertically installed on the base 1.

[0045] The casting hopper 3 is a triangular prism-shaped bucket structure with a casting groove 31. The casting hopper 3 is located on the side of the base 1 away from the wall 101 to be filled, and between the two slide rails 2. One end of the casting groove 31 is connected to the casting port 11, and the other end of the casting groove 31 opens upward to allow concrete to enter. The concrete enters the casting space 105 through the casting groove 31 and the casting port 11.

[0046] In this embodiment, it is preferable that the bottom edge of the opening of the pouring trough 31 near the base 1 is not lower than the bottom edge of the pouring port 11, and the bottom wall of the pouring trough is inclined downward towards the pouring port 11, that is, the concrete entering the pouring trough 31 can enter the pouring space 105 through the pouring port 11 along the bottom wall of the pouring trough 31.

[0047] The baffle 4 is a rectangular plate structure. It is located on the side of the base 1 opposite to the wall 101 to be filled and abuts against the end face of the base 1. The baffle 4 is positioned between two slide rails 2, and both sides of the baffle 4 are slidably engaged with the slide rails 2, allowing the baffle 4 to slide vertically relative to the base 1. The bottom of the pouring hopper 3 has a clearance opening 32 for the baffle 4 to slide into the pouring trough 31. The size of the clearance opening 32 is adapted to the cross-sectional dimensions of the baffle 4.

[0048] Reference Figure 2 and Figure 3 The sliding process of the baffle 4 relative to the base 1 is restricted. When the baffle 4 slides down to the limit position, the top of the baffle 4 is exactly in the clearance opening 32. When the baffle 4 slides up to the limit position, part of the baffle 4 is in the pouring groove 31, and at this time the part of the baffle 4 in the pouring groove 31 can cover the pouring opening 11, separating the pouring groove 31 from the pouring opening 11.

[0049] The guide plate 5 is a rectangular plate structure. The guide plate 5 is located in the pouring trough 31. One end of the guide plate 5 is close to the opening of the pouring trough 31 away from the pouring port 11 and is rotatably connected to the pouring hopper 3. The rotation axis of the guide plate 5 is horizontal and parallel to the plane of the base 1.

[0050] The other end of the guide plate 5 is close to the pouring opening 11. When the baffle 4 slides downward to its limit position, the guide plate 5 abuts against the bottom wall of the pouring trough 31 under its own weight, and the end of the guide plate 5 near the pouring opening 11 is above the baffle 4 and abuts against the top of the baffle 4. During the upward sliding of the baffle 4, the end of the guide plate 5 near the pouring opening 11 remains abutting against the top of the baffle 4. The baffle 4 will drive the end of the guide plate 5 near the pouring opening 11 to move upward, thereby driving the guide plate 5 to rotate away from the bottom wall of the pouring trough 31. The end of the guide plate 5 near the pouring opening 11 will pass through the pouring opening 11 and enter the pouring space 105. When the baffle 4 slides upward to its limit position, it is preferable that the guide plate 5 rotates to a horizontal state at this time.

[0051] The end face of the guide plate 5 away from the bottom wall of the pouring trough 31 is an inclined surface. When the guide plate 5 is rotated to a horizontal state, the end of the inclined surface close to the pouring space 105 is the lower inclined end. At this time, the concrete on the guide plate 5 can still move towards the pouring space 105.

[0052] After the concrete enters the pouring trough 31, it moves along the guide plate 5 and then enters the pouring space 105 through the pouring opening 11. During the pouring process, pouring begins with the baffle 4 sliding downwards to its limit position. When the concrete in the pouring space 105 is about to be higher than the pouring opening 11, the pouring speed can be appropriately slowed down, while the baffle 4 is gradually controlled to slide upwards, so that the baffle 4 gradually covers the pouring opening 11, effectively reducing the amount of concrete in the pouring space 105 overflowing into the pouring trough 31 by crossing the baffle 4. Furthermore, as the baffle 4 slides upwards, the inclination of the guide plate 5 gradually decreases, so that the speed at which the concrete enters the pouring space 105 through the pouring opening 11 via the guide plate 5 gradually decreases. This makes it easier for construction personnel to control the pouring speed of the concrete and reduces the probability of too much concrete overflowing the baffle 4 and entering the pouring trough 31 due to excessively fast pouring speed.

[0053] Reference Figure 1 and Figure 4 Furthermore, the top casting formwork of the structural column also includes a driving component 6 for controlling the sliding of the baffle 4. The driving component 6 is installed at the bottom of a slide rail 2 and is rotatably connected to the slide rail 2. The rotation axis of the driving component 6 is parallel to the rotation axis of the guide plate 5. The end of the driving component 6 near the baffle 4 has a gear structure 61, and the side of the baffle 4 near the driving component 6 has a rack structure 41. The rack structure 41 is distributed along the sliding direction of the baffle 4 on the side of the baffle 4. The gear structure 61 is located on the side of the rack structure 41 away from the base 1, and the gear structure 61 meshes with the rack structure 41. The end of the driving component 6 away from the rack structure 41 has an operating part 62, which facilitates the construction personnel to control the rotation of the driving component 6 relative to the slide rail 2. In this embodiment, the operating part 62 is preferably a rod-shaped structure extending radially outward. Preferably, the driving component 6 passes through both slide rails 2, and each slide rail 2 has a gear structure 61. The sides of the baffle 4 each have a rack structure 41 that meshes with the gear structure 61.

[0054] When the construction worker controls the drive component 6 to rotate relative to the slide rail 2 via the operating unit 62, the gear structure 61 meshes with the rack structure 41, driving the baffle 4 to slide vertically relative to the slide rail 2. In this embodiment, preferably, the resistance that the drive component 6 needs to overcome to rotate relative to the slide rail 2 is much greater than the weight of the baffle 4. That is, during the concrete pouring process, after the force exerted by the concrete on the guide plate 5 is transmitted to the baffle 4, the baffle 4 will not slide downward on its own, causing the drive component 6 to rotate.

[0055] Back Figure 2 and Figure 3Furthermore, the top of the baffle 4 is preferably a wedge-shaped structure, that is, the top of the baffle 4 has a wedge-shaped surface 42. The wedge-shaped surface 42 is located on the side of the baffle 4 away from the base 1. When the baffle 4 slides downward to its limit position, the wedge-shaped surface 42 is located in the relief opening 32, and there is a gap between the wedge-shaped surface 42 and the opening wall of the relief opening 32. At this time, the wedge-shaped surface 42 makes it easier for the baffle 4 to slide upward through the relief opening 32.

[0056] Furthermore, the top of the preferred baffle 4 is provided with several first leakage ports 43, which penetrate the baffle 4. When the top of the baffle 4 passes through the relief opening 32 and enters the pouring trough 31, the two ends of the first leakage ports 43 are respectively connected to the pouring trough 31 and the pouring opening 11. The several first leakage ports 43 are evenly distributed at the top of the baffle 4 in the horizontal direction. A small amount of concrete at the top of the pouring space 105 can overflow into the pouring trough 31 through the several first leakage ports 43, and the overflowing concrete will flow along the wedge-shaped surface 42 to the end face of the baffle 4 away from the base 1.

[0057] The bottom of the preferred pouring hopper 3 is also provided with several second leakage ports 33. The second leakage ports 33 penetrate the pouring hopper 3, the upper end of the second leakage ports 33 communicates with the pouring trough 31, the lower end of the second leakage ports 33 communicates with the space below the pouring hopper 3, and one side of the second leakage ports 33 communicates with the relief port 32. The several second leakage ports 33 are evenly distributed at the bottom of the pouring hopper 3 in the horizontal direction. The concrete flowing down along the end face of the baffle 4 can flow through the several second leakage ports 33 and through the relief port 32 to the part of the baffle 4 located outside the pouring trough 31.

[0058] Furthermore, the bottom of the baffle 4 preferably has a receiving part 44, which extends outward from the bottom of the baffle 4 towards the side opposite to the base 1. During the sliding process of the baffle 4, the receiving part 44 is always located below the pouring hopper 3; a receiving groove 45 is formed between the receiving part 44 and the baffle 4, so that after the concrete flows down along the end face of the baffle 4, it can flow into the receiving groove 45 and stay in the receiving groove 45, reducing the probability of the concrete flowing directly down to the ground of the construction site.

[0059] Construction workers can determine the concrete pouring status in the pouring space 105 by observing the flow of concrete from several second seepage outlets 33. When concrete flows out from a second seepage outlet 33, it indicates that the concrete level in the pouring space 105 is higher than the baffle 4, requiring control of the baffle 4 to continue sliding upwards. This reduces the construction difficulty of pouring at the top of the structural column, further reduces concrete waste, and minimizes concrete remaining in the pouring trough 31.

[0060] Back Figure 1 and Figure 2Furthermore, the top casting formwork of the structural column also includes a cleaning component 7 for cleaning the concrete left on the end face of the baffle 4. The cleaning component 7 is a cylindrical structure and is located between the two slide rails 2. One end of the cleaning component 7 is fixedly connected to the driving component 6 in the axial direction. The axis of the cleaning component 7 coincides with the rotation axis of the driving component 6, and the rotation of the driving component 6 will drive the cleaning component 7 to rotate.

[0061] The cleaning component 7 is located on the side of the baffle 4 away from the base 1. The cleaning component 7 abuts against the end face of the baffle 4, and the cleaning component 7 remains abutting against the baffle 4 during the sliding process of the baffle 4. In this embodiment, the cleaning component 7 is preferably a combination of a roller covered with a highly absorbent towel, and the towel is detachable and replaceable relative to the roller; in other embodiments, the towel can also be made of sponge material.

[0062] After the concrete flows out of the second leakage port 33 and down the end face of the baffle 4, it will flow onto the surface of the cleaning component 7. The cleaning component 7 can keep the concrete on its own surface. At the same time, as the control drive component 6 drives the baffle 4 to slide upward, the contact position between the cleaning component 7 and the baffle 4 changes, so that the surface of the cleaning component 7 is in uniform contact with the end face of the baffle 4, improving the cleaning effect of the cleaning component 7. In addition, the baffle 4 also moves relative to the cleaning component 7 during the sliding process, thereby expanding the cleaning range of the cleaning component 7 on the end face of the baffle 4, further improving the cleaning effect of the cleaning component 7 and reducing the amount of concrete residue solidified on the surface of the baffle 4.

[0063] Reference Figure 3 and Figure 5 Furthermore, the bottom of the pouring hopper 3 and the slide rails 2 on both sides are rotatably connected, and the rotation axis of the pouring hopper 3 is parallel to the rotation axis of the guide plate 5. When the baffle 4 slides upward to its limit position, the baffle 4 blocks the pouring port 11, and the pouring space 105 is filled with concrete, thus completing the pouring. At this time, controlling the pouring hopper 3 to rotate away from the base 1 allows the construction personnel to easily pour out the concrete left on the guide plate 5 in the pouring trough 31, and facilitates the construction personnel to clean the pouring hopper 3 and the guide plate 5 before the concrete in the pouring trough 31 solidifies.

[0064] During the rotation of the pouring hopper 3 relative to the base 1, the receiving part 44 will limit the movement of the pouring hopper 3, and the baffle 4 has a relief groove 46 near the receiving part 44 to provide space for the pouring hopper 3 to rotate. When the pouring hopper 3 rotates to its limit position away from the base 1, the bottom of the pouring hopper 3 abuts against the receiving part 44, and the bottom of the pouring hopper 3 abuts against the wall of the relief groove 46.

[0065] When the pouring hopper 3 rotates with the guide plate 5 in a horizontal position, and after the pouring hopper 3 rotates to its limit position in the direction away from the base 1, the guide plate 5 will tilt downward in the direction away from the base 1, so that the concrete left on the guide plate 5 in the pouring trough 31 can be poured out.

[0066] Furthermore, both ends of the guide plate 5 extend outward through the pouring hopper 3 along its own rotation axis and each has a locking part 51, with the two locking parts 51 located on both sides of the pouring hopper 3 respectively; on the track, in the direction away from the base 1, there are locking frames 21 that are adapted to the locking parts 51, with the two locking frames 21 corresponding to the two locking parts 51 one by one, and the two locking frames 21 located on both sides of the pouring hopper 3 respectively.

[0067] In this embodiment, the snap-fit ​​part 51 is preferably a strip-shaped structure. The snap-fit ​​bracket 21 is provided with a snap-fit ​​groove 211 that is adapted to the snap-fit ​​part 51. Preferably, the cross-section of the snap-fit ​​groove 211 is circular. When the pouring hopper 3 is in a state of rotating to the limit position in the direction close to the base 1, during the rotation of the guide plate 5 relative to the pouring hopper 3, the snap-fit ​​part 51 can rotate freely in the snap-fit ​​groove 211 about the rotation axis of the guide plate 5.

[0068] The clamping frame 21 is also provided with a guide groove 212. The guide groove 212 is located on the side of the clamping groove 211 away from the slide rail 2. The trajectory of the guide groove 212 is an arc with the rotation axis of the casting bucket 3 as the axis. One end of the guide groove 212 near the slide rail 2 is connected to the clamping groove 211, and the other end of the guide groove 212 passes through the clamping frame 21.

[0069] When the pouring hopper 3 is rotated to its limit position in the direction close to the base 1 and the guide plate 5 is not rotated to a horizontal position, the locking part 51 will be locked in the locking groove 211. That is, the position of the locking part 51 at this time cannot enter the guide groove 212 from the locking groove 211. Therefore, the pouring hopper 3 cannot rotate relative to the slide rail 2 at this time.

[0070] When the pouring hopper 3 is rotated to its limit position towards the base 1 and the guide plate 5 is in a horizontal state, the position of the locking part 51 is exactly aligned with and adapted to the guide groove 212. That is, when the pouring hopper 3 is rotated relative to the slide rail 2 away from the base 1, the locking part 51 can enter the guide groove 212 from the locking groove 211 and move along the guide groove 212.

[0071] In this embodiment, the end of the guide groove 212 away from the slide rail 2 passes through the snap-fit ​​bracket 21, solely to facilitate the connection between the pouring hopper 3 and the snap-fit ​​bracket 21. During use, when the pouring hopper 3 rotates to its limit position away from the base 1, the snap-fit ​​part 51 will be located in the guide groove 212, and at the same time, the bottom of the pouring hopper 3 will remain abutted against the receiving part 44.

[0072] Furthermore, the guide plate 5 has a contact portion 52 at the end away from the snap-fit ​​portion 51, and the cross-section of the contact portion 52 is larger than the cross-section of other parts of the guide plate 5. When the guide plate 5 rotates to the point where there is a gap between itself and the wall of the pouring trough 31, the contact portion 52 will pass through the pouring port 11 and be located in the pouring space 105 to contact the concrete located at the top of the pouring space 105.

[0073] When the guide plate 5 slides and rotates to a horizontal state with the baffle 4, the contact part 52 is located at the top of the pouring space 105 at the maximum extent. The concrete at the top of the pouring space 105 will exert a force on the contact part 52, driving it away from the pouring space 105. At this time, the force of the concrete on the contact part 52 will drive the pouring bucket 3 to rotate to the limit position in the direction away from the base 1, so that the pouring bucket 3 can rotate on its own according to the pouring situation, which is convenient for construction personnel to use.

[0074] Furthermore, the contact portion 52 has several protruding blocks 521, each corresponding to a first leakage port 43 on the baffle 4. When the pouring hopper 3 rotates to its limit position away from the base 1, the contact portion 52 will come into contact with the top of the baffle 4. At this time, the end face of the contact portion 52 near the pouring space 105 will be flush with the end face of the baffle 4 near the pouring opening 11, and the blocks 521 will block the first leakage ports 43 respectively, preventing the concrete at the top of the pouring space 105 from overflowing through the first leakage ports 43. As a result, after the concrete in the pouring space 105 solidifies, the end face of the top of the structural column near the pouring opening 11 has a high degree of flatness, greatly reducing the amount of chiseling work required.

[0075] The implementation principle of the casting formwork for the top of a structural column in this application embodiment is as follows:

[0076] After the formwork for pouring concrete at the top of the structural column is installed, concrete is poured into the pouring space 105 through the pouring hopper 3 and the guide plate 5. After entering the pouring trough 31, the concrete flows along the guide plate 5 through the pouring port 11 and finally into the pouring space 105. When the concrete is poured to the point where concrete flows out from the second leakage port 33, the pouring speed is reduced. At the same time, the drive component 6 is controlled to rotate, driving the baffle 4 to slide upward until the baffle 4 slides upward to its limit position. During the process of controlling the drive component 6, the cleaning component 7 can also clean the concrete left on the surface of the baffle 4. At this time, the guide plate 5 rotates to a horizontal state, and the concrete at the top of the pouring space 105 will drive the pouring hopper 3 to rotate through the guide plate 5. After the pouring hopper 3 rotates to its limit position, it is convenient for construction personnel to clean the pouring hopper 3 and the guide plate 5. At the same time, the baffle 4 covers the pouring port 11, which is convenient for the concrete filling the pouring space 105 to solidify and form. Ultimately, this can improve the quality of the top of the structural column after it is poured and formed, greatly reduce the amount of subsequent chiseling work, and also make it convenient for the formwork for pouring concrete at the top of the structural column to be reused after cleaning.

[0077] 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.
