Description

An external climbing and turning combined template system and method Technical Field

[0001] This invention belongs to the field of bridge construction technology, and in particular relates to an external climbing and overturning combined formwork system and method. Background Technology

[0002] With the continuous innovation of bridge pier construction technology and the strengthening of safety requirements, bridge pier construction equipment is constantly developing towards intelligence, safety, and efficiency. Hollow thin-walled piers, as a common type of bridge pier structure in China, have advantages such as large section modulus, small cross-sectional area, light weight, and high cross-sectional stiffness and strength. Currently, the construction of hollow thin-walled piers in China mainly adopts flip-form, slip-form, and climbing formwork methods. Flip-form construction no longer meets the current domestic construction safety requirements, slip-form is complex to operate, has poor appearance quality, and requires high precision, while traditional hydraulic climbing formwork has disadvantages such as many operating procedures, complex installation and dismantling processes, and high manufacturing costs. Therefore, there is an urgent need for a climbing-flip combined formwork that is easy to operate, has low technical difficulty, and is economical to meet the application requirements of hollow thin-walled pier construction with various cross-sections. Technical issues

[0003] Currently, the most common formwork types for hollow thin-walled pier construction include: The first is a flip-form system, where the formwork and operating platform are integrated. After removing one section, it is flipped over to install the next. The system is primarily secured to the pier with tie bolts. Formwork installation and removal involve hoisting large components and require workers to pry the formwork, posing high safety risks and thus being phased out. The second is a slipform system, which requires steel reinforcement binding and stiffening frame construction to be completed within a specified time before each slipform operation, and the appearance quality is unsatisfactory. The third is a traditional hydraulic climbing formwork system. While highly intelligent and safe, this system is more expensive than other forms due to the large number and high cost of hydraulic equipment, as well as higher maintenance costs. Therefore, there is an urgent need to design an externally mounted climbing and flipping combined formwork system and method to solve the aforementioned problems. Technical solutions

[0004] The purpose of this invention is to provide an external climbing and turning combined formwork system and method, which has the advantages of low construction risk, simple operation and low cost of variable cross-section hollow thin-walled piers, and solves the problems mentioned in the background art.

[0005] To achieve the above objectives, the specific technical solution of the external climbing and turning combined template system and method of the present invention is as follows:

[0006] An external climbing and turning combined template system includes an operating platform and a climbing component. The climbing component is connected to the operating platform to drive the operating platform to climb.

[0007] The operating platform is connected to a shaped template, which can slide relative to the operating platform to adjust the distance between the shaped template and the pier column. It can also be used to cast pier columns with variable cross-sections when the cross-section of the pier column changes.

[0008] Furthermore, a template hanger is fixedly connected to the operating platform. A sliding groove is provided on the template hanger. A sliding rod is slidably connected to the sliding groove. The sliding rod is connected to the shaped template. A rotating rod is rotatably connected to the sliding rod. A moving wheel is fixedly connected to the rotating rod. The moving wheel is rotatably connected to the template hanger.

[0009] Furthermore, the operating platform includes a frame with a truss on it. A safe distance is provided between the truss and the pier. A sliding groove is provided on the frame, and the frame is slidably connected to the truss through the sliding groove to ensure that a safe distance is maintained between the truss and the pier. The truss is connected to the prefabricated template.

[0010] Furthermore, a threaded sleeve is fixedly connected to the sleeve, and a threaded rod is screwed onto the threaded sleeve. One end of the threaded rod is rotatably connected to the truss, and a hand-operated frame is fixedly connected to the end of the threaded rod away from the truss.

[0011] Furthermore, the climbing assembly includes a bracket and an attachment. The bracket is connected to the pier column via pre-embedded bolts and sleeves. A hydraulic cylinder is installed on the bracket, and the output end of the hydraulic cylinder is connected to the operating platform. The attachment is connected to the pier column via pre-embedded bolts and sleeves. A support column is installed on the attachment, and the end of the support column away from the attachment is connected to the operating platform. A wall-mounted support is installed on the attachment, and the end of the wall-mounted support away from the attachment is connected to the support column. A wall-mounted diagonal support is installed on the attachment, and the end of the wall-mounted diagonal support away from the attachment is connected to the support column or the bracket.

[0012] Furthermore, a locking strip is fixedly connected to the template hanger, and a locking tooth is rotatably connected to the rotating rod. The locking tooth can engage with the locking strip, and a push rod is fixedly connected to the locking tooth. The locking tooth has an engaged state and a disengaged state.

[0013] When the locking teeth are engaged, they engage with the locking strip, keeping the moving wheel stationary;

[0014] When the locking teeth are in the disengaged state, the locking teeth are no longer engaged with the locking strip, allowing the moving wheels to roll relative to the template hanger.

[0015] Furthermore, a limiter is rotatably connected to the rotating rod, which can limit the movement of the moving wheel. A sliding groove is provided on the template hanger, and the template hanger is slidably connected to the limiter through the sliding groove. An inclined surface is provided on the limiter, and the limiter cooperates with the locking teeth through the inclined surface. The limiter has a limited state and an unlimited state.

[0016] When the limit switch is in the limit position, the locking teeth abut against the inclined surface of the limit switch, causing the limit switch to contact the moving wheel and limit the moving wheel.

[0017] When the limit switch is in the unlimited state, the locking teeth separate from the limit switch, causing the limit switch to reset and cancel contact with the moving wheel, and the moving wheel can roll relative to the template hanger.

[0018] Furthermore, the template includes a first template and a second template, which are combined to form the casting cavity of the pier column. The first template is located at the inclined end of the casting section of the pier column, and the second template is located at the vertical end of the casting section of the pier column.

[0019] The second template includes multiple single templates. The single templates connected to the first template are divided along a diagonal line into a first inclined plate and a second inclined plate. When the pier column is poured at an inclination, the first inclined plate is removed, so that the first template is connected to the second inclined plate, making the pier column pouring section inclined. Then, when pouring upwards, the single template adjacent to the second inclined plate is removed, and the second inclined plate is moved to the position of the single template, so that the pier column pouring section has an inclination.

[0020] Furthermore, the first inclined plate and the second inclined plate are slidably connected by a groove, the second inclined plate and the single template are slidably connected by a groove, and the single templates are slidably connected by a groove. The first inclined plate, the second inclined plate and the single template are all provided with screw holes. After the first inclined plate, the second inclined plate and the single template are slidably connected, they are fixed by bolts.

[0021] An external climbing and turning combined template method, using an external climbing and turning combined template system, includes the following steps:

[0022] S1. Pre-embedded bolts and sleeves are installed during the construction of the first concrete pier column;

[0023] S2. Install the climbing assembly and operating platform on the first concrete pier column;

[0024] S3. After fixing the template, pour the concrete.

[0025] S4. After the pouring is completed, the hydraulic cylinder and support column are alternately and vertically raised and fixed to the bracket and attachment in order to raise the shaped template and the operating platform.

[0026] S5. When the pier column is inclined, remove the first inclined plate and connect the first formwork with the second inclined plate before pouring.

[0027] S6. After the pouring is completed, climb upwards, then remove the single formwork adjacent to the second inclined plate, and move the second inclined plate to the position where the single formwork was removed. Connect the first formwork to the moved second inclined plate and pour the concrete. Beneficial effects

[0028] It has the capability to perform pouring construction on piers with inclined surfaces, and the construction is simple, requiring no crane. It also ensures that the operating platform always maintains a safe distance from the pier, which complies with safe construction specifications. Attached Figure Description

[0038] An external climbing and turning combined template method, using an external climbing and turning combined template system, includes the following steps:

[0039] S1. During the construction of the first concrete pier column 1, pre-embedded bolts and pre-embedded sleeves are pre-embedded.

[0040] S2. Install the climbing assembly 3 and the operating platform 2 on the first concrete pier 1;

[0041] Specifically, the corbel 31 is connected to the first concrete pier 1 by pre-embedded bolts and pre-embedded sleeves, the attachment 32 is connected to the first concrete pier 1 by pre-embedded bolts and pre-embedded sleeves, then the hydraulic cylinder 33 is installed on the corbel 31, and the output end of the hydraulic cylinder 33 is connected to the operating platform 2. Then the support column 34 is installed on the attachment 32, and the fixed template 4 is installed on the operating platform 2.

[0042] S3. After fixing the template 4, pour the concrete.

[0043] Specifically, adjacent templates 4 are fixed with bolts, and opposite templates 4 are fixed with tie bolts, and then the concrete is poured.

[0044] S4. After the pouring is completed, the hydraulic cylinder 33 and the support column 34 are alternately vertically climbed and fixed to the bracket 31 and the attachment 32 to climb the mold 4 and the operating platform 2.

[0045] Specifically, after the concrete is poured and solidified, the hydraulic cylinder 33 is removed from and installed on the first bracket 31. Then, the hydraulic cylinder 33 is retracted upwards until it is flush with the second bracket 31. The hydraulic cylinder 33 is then connected to the second bracket 31. The support column 34 is then removed from and installed on the first attachment 32. The hydraulic cylinder 33 drives the operating platform 2 to climb upwards. After the climbing is completed, the support column 34 is fixed to the second attachment 32. At this time, the operating platform 2 is located above the completed pier 1, and then pouring can be carried out again.

[0046] S5. When the section of the pier column 1 is inclined, the first inclined plate 44 is removed, so that the first template 41 is connected to the second inclined plate 45, and then the pouring is carried out.

[0047] Specifically, when the section of the pier column 1 to be poured is inclined, the first inclined plate 44 is removed, so that the first template 41 is tilted and connected to the second inclined plate 45 by bolts. The diagonal lines dividing the first inclined plate 44 and the second inclined plate 45 correspond to the inclination of the pouring section of the pier column 1. After the fixed template 4 is fixed, the pouring is carried out.

[0048] S6. After the pouring is completed and the concrete has solidified, the operating platform 2 climbs up again, then removes the single formwork 43 adjacent to the second inclined plate 45, and moves the second inclined plate 45 to the position where the single formwork 43 was removed. The first formwork 41 is then connected to the moved second inclined plate 45 for pouring.

[0049] Specifically, after the concrete is poured and solidified, the hydraulic cylinder 33 is removed and installed from the second bracket 31. Then, the hydraulic cylinder 33 is retracted upwards until it is flush with the third bracket 31. The hydraulic cylinder 33 is then connected to the third bracket 31. The support column 34 is then removed and installed from the second attachment 32. The hydraulic cylinder 33 drives the operating platform 2 to climb upwards. After climbing, the support column 34 is fixed to the third attachment 32. At this time, the operating platform 2 is located above the poured pier 1. Then, the single template 43 adjacent to the second inclined plate 45 is removed, and the second inclined plate 45 is moved to the position of the removed single template 43. The width of the single template 43 corresponds to the inclination of the poured section of the pier 1. Then, the first template 41 and the second inclined plate 45 are connected by bolts so that the inclination of the poured section of the pier 1 can always be maintained. After the fixed template 4 is fixed, the concrete is poured again.

[0050] This process is repeated until the pouring is complete. Embodiments of the present invention

[0051] This template system includes an operating platform 2 and a climbing component 3. The climbing component 3 is connected to the operating platform 2 to drive the operating platform 2 to climb. A fixed template 4 is connected to the operating platform 2. When the climbing component 3 drives the operating platform 2 to climb, the fixed template 4 can slide relative to the operating platform 2 to adjust the distance between the fixed template 4 and the pier 1. When the cross section of the pier 1 changes, the pier 1 with an inclination can be poured.

[0052] A template hanger 5 is fixedly connected to the operating platform 2. A sliding groove is provided on the template hanger 5, and a sliding rod 54 is slidably connected to the sliding groove. The sliding rod 54 is connected to the shaped template 4. A rotating rod 53 is rotatably connected to the sliding rod 54, and a movable wheel 52 is fixedly connected to the rotating rod 53. The movable wheel 52 is rotatably connected to the template hanger 5. By setting the shaped template 4 to slide relative to the template hanger 5, the distance between the shaped template 4 and the pier 1 can be adjusted. By setting the movable wheel 52, the effect of facilitating the movement of the shaped template 4 is achieved.

[0053] Specifically, a tensioner 6 is connected to the sliding rod 54. The end of the tensioner 6 away from the sliding rod 54 is connected to the shaping template 4, so that the up and down movement of the shaping template 4 can be adjusted by the tensioner 6.

[0054] Specifically, an external protective steel mesh is installed on the outside of the operating platform 2 to form an external protective system for the template system.

[0055] A locking strip 51 is fixedly connected to the template hanger 5, and a locking tooth 56 is rotatably connected to the rotating rod 53. The locking tooth 56 can engage with the locking strip 51. A push rod 55 is fixedly connected to the locking tooth 56. The locking tooth 56 has an engaged state and a disengaged state.

[0056] When the locking tooth 56 is engaged, the locking tooth 56 engages with the locking strip 51, causing the moving wheel 52 to stop. Thus, the shaping template 4 cannot move relative to the template hanger 5, and at this time the push rod 55 is in a free state and is in contact with the template hanger 5.

[0057] When the locking teeth 56 are in the disengaged state, the manual push rod 55 is lifted, causing the manual push rod 55 to rotate around the rotating rod 53. Since the manual push rod 55 is fixedly connected to the locking teeth 56, the locking teeth 56 also rotate around the rotating rod 53, causing the locking teeth 56 to disengage from the locking strip 51. As a result, the moving wheel 52 can roll relative to the formwork hanger 5. The manual push rod 55 can be pushed forward or backward to make the moving wheel 52 slide forward or backward relative to the formwork hanger 5, thereby changing the distance between the fixed formwork 4 and the pier column 1.

[0058] A limiter 57 is rotatably connected to the rotating rod 53. The limiter 57 can limit the movement wheel 52. A sliding groove is provided on the template hanger 5. The template hanger 5 is slidably connected to the limiter 57 through the sliding groove. An inclined surface is provided on the limiter 57. The limiter 57 cooperates with the locking tooth 56 through the inclined surface. The limiter 57 has a limited state and an unlimited state.

[0059] When the limiter 57 is in the limited state, the cleat 56 abuts against the inclined surface of the limiter 57, causing the limiter 57 to slide towards the moving wheel 52, so that the limiter 57 contacts the moving wheel 52 and limits the moving wheel 52. As a result, the shaping template 4 cannot move relative to the template hanger 5, and at this time the push rod 55 is in a free state and contacts the template hanger 5.

[0060] When the limiter 57 is in the unlimited state, the manual push rod 55 is lifted, causing the push rod 55 to rotate around the rotating rod 53. Since the push rod 55 is fixedly connected to the locking tooth 56, the locking tooth 56 also rotates around the rotating rod 53. The locking tooth 56 separates from the inclined surface of the limiter 57, causing the limiter 57 to reset and cancel contact with the moving wheel 52. The moving wheel 52 can then roll relative to the formwork hanger 5. Subsequently, the manual push rod 55 can be pushed forward or backward to make the moving wheel 52 slide forward or backward relative to the formwork hanger 5, thereby changing the distance between the fixed formwork 4 and the pier column 1.

[0061] The operating platform 2 includes a sleeve 23, on which a truss 22 is provided. A safe distance is provided between the truss 22 and the pier 1. A sliding groove is provided on the sleeve 23. The sleeve 23 is slidably connected to the truss 22 through the sliding groove to ensure that a safe distance is maintained between the truss 22 and the pier 1. The truss 22 is connected to the fixed template 4.

[0062] Since the two sides of the pier 1 are inclined, a sleeve 23 is provided at the end corresponding to the pier 1. The truss 22 can slide relative to the sleeve 23, so that the distance between the truss 22 and the pier 1 can be kept constant, which complies with the regulations for safe construction.

[0063] Preferably, a sleeve 23 and a truss 22 are provided at the two inclined side ends of the pier 1. The truss 22 and the sleeve 23 can slide relative to each other. A non-sliding truss 22 is provided at the two vertical side ends of the pier 1, so that only the truss 22 at the two inclined side ends of the pier 1 can slide. In other embodiments of the present invention, trusses 22 and sleeves 23 can also be provided at all four side ends of the pier 1, so that the trusses 22 at all four side ends of the pier 1 can slide.

[0064] Furthermore, when all four sides of the pier 1 are inclined, trusses 22 and sleeves 23 can be installed on all four sides of the pier 1, so that the trusses 22 on all four sides of the pier 1 can slide.

[0065] A threaded sleeve is fixedly connected to the sleeve 23, and a threaded rod 21 is screwed onto the threaded sleeve. One end of the threaded rod 21 is rotatably connected to the truss 22, and a hand-operated frame is fixedly connected to the end of the threaded rod 21 away from the truss 22. By rotating the hand-operated frame, the threaded rod 21 rotates synchronously. Since the threaded rod 21 is screwed onto the threaded sleeve, the threaded rod 21 can slide relative to the truss 22 while rotating. Furthermore, since the threaded rod 21 is rotatably connected to the truss 22, and the truss 22 is limited by the sleeve 23, the truss 22 slides with the threaded rod 21 without rotating, so that the distance between the truss 22 and the pier 1 can be adjusted.

[0066] The climbing assembly 3 includes a bracket 31 and an attachment 32. The bracket 31 is connected to the pier 1 via pre-embedded bolts and sleeves. A hydraulic cylinder 33 is installed on the bracket 31, and the output end of the hydraulic cylinder 33 is connected to the operating platform 2. The attachment 32 is connected to the pier 1 via pre-embedded bolts and sleeves. A support column 34 is installed on the attachment 32, and the end of the support column 34 away from the attachment 32 is connected to the operating platform 2. A wall-mounted support 36 is installed on the attachment 32, and the end of the wall-mounted support 36 away from the attachment 32 is connected to the support column 34. A wall-mounted diagonal support 35 is installed on the attachment 32, and the end of the wall-mounted diagonal support 35 away from the attachment 32 is connected to the support column 34 or the bracket 31.

[0067] By setting up hydraulic cylinder 33, the operating platform 2 is driven to climb upward; by setting up support column 34, the operating platform 2 is supported; by setting up bracket 31 and attachment 32, the hydraulic cylinder 33 and support column 34 are supported.

[0068] The template 4 includes a first template 41 and a second template 42, which are combined to form the casting cavity of the pier column 1. The first template 41 is located at the inclined end of the casting section of the pier column 1, and the second template 42 is located at the vertical end of the casting section of the pier column 1.

[0069] The second template 42 includes multiple single templates 43. The single templates 43 connected to the first template 41 are divided along a diagonal line into a first inclined plate 44 and a second inclined plate 45. When the pier column 1 is poured with an inclined section, the first inclined plate 44 is removed, so that the first template 41 is connected to the second inclined plate 45, making the pier column 1 pouring section inclined. Then, when pouring upwards, the single template 43 adjacent to the second inclined plate 45 is removed, and the second inclined plate 45 is moved to the position of the single template 43, so that the pier column 1 pouring section has an inclination.

[0070] The diagonal lines dividing the single template 43 correspond to the inclined surface of the pier column 1.

[0071] The first inclined plate 44 and the second inclined plate 45 are slidably connected by a groove. The second inclined plate 45 and the single template 43 are slidably connected by a groove. The single templates 43 are also slidably connected by a groove. Each of the first inclined plate 44, the second inclined plate 45, and the single template 43 is provided with screw holes. After the first inclined plate 44, the second inclined plate 45, and the single template 43 are slidably connected, they are fixed by bolts. By setting the first inclined plate 44 and the second inclined plate 45 to be slidably connected by a groove, the second inclined plate 45 and the single template 43 to be slidably connected by a groove, and the single templates 43 to be slidably connected by a groove, the advantages of easy assembly and disassembly, saving time and effort are achieved. The amount of bolts used is reduced, and it is only necessary to fix them with bolts at both ends.

[0072] After the concrete is poured and solidified, the hydraulic cylinder 33 is removed and installed from the second bracket 31. Then, the hydraulic cylinder 33 is retracted upwards until it is flush with the third bracket 31. The hydraulic cylinder 33 is then connected to the third bracket 31. The support column 34 is then removed and installed from the second attachment 32. The hydraulic cylinder 33 drives the operating platform 2 to climb upwards. After climbing, the support column 34 is fixed to the third attachment 32. At this time, the operating platform 2 is located above the poured pier 1. Then, the single template 43 adjacent to the second inclined plate 45 is removed, and the second inclined plate 45 is moved to the position of the removed single template 43. The width of the single template 43 corresponds to the inclination of the poured section of the pier 1. Then, the first template 41 and the second inclined plate 45 are connected by bolts so that the inclination of the poured section of the pier 1 can always be maintained. After the fixed template 4 is fixed, the concrete is poured again. Industrial applicability

[0073] It has the capability to perform pouring construction on piers with inclined surfaces, and the construction is simple, requiring no crane. It also ensures that the operating platform always maintains a safe distance from the pier, which complies with safe construction specifications.
