Description

Technical Field

[0001] This application relates to the field of building construction, and in particular to a formwork support for tall load-bearing structures and its construction method. Background Technology

[0002] Construction formwork is a temporary support structure, made according to design requirements, to shape concrete structures and components in the specified positions and geometric dimensions, maintain their correct positions, and bear the self-weight of the formwork and the external loads acting on it. The purpose of formwork engineering is to ensure the quality and safety of concrete engineering, accelerate the construction progress, and reduce project costs.

[0003] For related technology, please refer to Chinese Utility Model Patent No. CN220117827U, which discloses a high-safety tall formwork support, including a support, a formwork, and a control component. The formwork is supported by a frame structure composed of multiple supports. A support plate is fixedly connected to the bottom of the support. The inner wall of the support plate is slidably connected to a post for insertion into the ground. The post is controlled to slide by the control component. The control component includes a control block and a top-pressure post. The inner wall of the control block is connected to the outer wall of the support through internal and external threads. One end of the top-pressure post extends to the inner wall of the control block, and the other end of the top-pressure post is fixedly connected to one end of the post. Rotating the control block causes the post to be inserted into the ground, thereby improving the stability of the support for the formwork.

[0004] Regarding the aforementioned technologies, when the ground is uneven, the bottom of the support cannot make good contact with the ground. In this case, workers need to lengthen the vertical support of the support, which involves a relatively limited range of procedures and results in low installation efficiency of the formwork support. Summary of the Invention

[0005] To address the issue of low installation efficiency of formwork supports, this application provides a tall load-bearing structure formwork support and its construction method.

[0006] Firstly, the technical solution provided in this application for a tall load-bearing structural formwork support is as follows: A tall load-bearing structural formwork support includes a formwork and a support fixedly connected to the formwork. The support includes multiple horizontal bars and multiple vertical bars. An extension component is installed on each vertical bar. The extension component includes an extension cylinder and an operating cylinder sleeved on the vertical bar. The extension cylinder is slidably connected to the vertical bar. The operating cylinder is located above the extension cylinder and is rotatably connected to the extension cylinder. An internal thread is formed on the inner circumferential surface of the operating cylinder. An external thread is formed on the outer circumferential surface of the vertical bar to cooperate with the internal thread on the operating cylinder.

[0007] By adopting the above technical solution, when the ground is uneven, the operating cylinder is rotated, which drives the extension cylinder to move. The extension cylinder lengthens the vertical rod. When the extension cylinder contacts the ground, the operating cylinder stops rotating, thus completing the support of the template. This facilitates operation by workers and improves the problem of low installation efficiency of template supports.

[0008] Preferably, the bottom of the extension tube is fixedly connected to a load-bearing plate placed below the vertical rod.

[0009] By adopting the above technical solution, the load-bearing plate increases the contact area between the extension tube and the ground, thereby improving the stability of the support for the template.

[0010] Preferably, a reinforcing component is installed on the load-bearing plate, the reinforcing component including a reinforcing plate hinged to the side wall of the load-bearing plate, the reinforcing plate being able to contact the ground, and a transmission component is installed on the extension cylinder, the operating cylinder being able to drive the reinforcing plate to rotate through the transmission component.

[0011] By adopting the above technical solution, during the movement of the extension cylinder, the operating cylinder can drive the reinforcing plate to rotate through the transmission component, so that the reinforcing plate comes into contact with the ground.

[0013] By adopting the above technical solution, during the movement of the extension cylinder, the operating cylinder drives the second gear to rotate, the second gear drives the first gear to rotate, the first gear drives the threaded cylinder to rotate, the threaded cylinder drives the screw to move, the screw drives the transmission rod to move, and the transmission rod drives the reinforcing plate to flip through the sliding component, so that the reinforcing plate contacts the ground, making it convenient for workers to operate.

[0014] Preferably, a first groove is formed on the end face of the reinforcing plate, and the sliding component includes a first slider placed in the first groove. The first slider can slide along the first groove, and the first slider is hinged to the transmission rod.

[0015] By adopting the above technical solution, during the movement of the transmission rod, the transmission rod drives the first slider to slide in the first slide groove. At the same time, the first slider drives the reinforcing plate to flip. The first slider restricts the movement trajectory of the reinforcing plate and improves the stability of the movement of the reinforcing plate.

[0016] Preferably, the top of the screw is provided with a smooth section, a limit plate is fixedly connected to the top of the screw, a return spring is fixedly connected to the bottom of the screw, and the end of the return spring away from the screw is fixedly connected to the mounting block.

[0017] By adopting the above technical solution, when the reinforcing plate contacts the ground, the smooth section on the screw moves into the threaded cylinder, the screw stops moving, the operating cylinder can continue to rotate, and the extension cylinder can continue to lengthen the vertical rod, further improving the stability of the support for the template.

[0018] Preferably, the bottom of the reinforcing plate is fixedly connected to a plurality of insert rods, and the ends of the plurality of insert rods away from the reinforcing plate are all tapered.

[0019] By adopting the above technical solution, during the process of the reinforcing plate being flipped, the reinforcing plate can drive multiple insertion rods to flip, so that multiple insertion rods are inserted into the ground, making the reinforcing plate more stable.

[0020] Preferably, the reinforcing components are provided in multiple sets, and the multiple sets of reinforcing components are evenly distributed around the center of the extension cylinder, and the transmission component is provided correspondingly to the reinforcing components.

[0021] By adopting the above technical solution, the stability of the support frame for the template has been further improved.

[0022] Preferably, a second sliding groove is vertically formed on the outer circumferential surface of the vertical rod, and a second slider placed in the second sliding groove is fixedly connected to the inner wall of the extension tube, and the second slider moves vertically along the second sliding groove.

[0023] By adopting the above technical solution, during the sliding process of the extension cylinder, the extension cylinder drives the second slider to slide in the second groove, thereby improving the stability of the extension cylinder's movement.

[0024] Secondly, the construction method for formwork support of tall load-bearing structures provided in this application adopts the following technical solution: A construction method for formwork supports for tall load-bearing structures includes the following steps: S1. First, use multiple horizontal bars and multiple vertical bars to build a support frame, and then fix the template to the support frame; S2. Then rotate the operating cylinder, which drives the extension cylinder to move, and the extension cylinder drives the load-bearing plate to move, so that the load-bearing plate contacts the ground. At the same time, the operating cylinder drives the second gear to rotate, the second gear drives the first gear to rotate, the first gear drives the threaded cylinder to rotate, the threaded cylinder drives the screw to move, the screw drives the transmission rod to move, and the transmission rod drives the reinforcing plate to flip. S3. After the reinforcing plate contacts the ground, the operating cylinder continues to rotate. At this time, the smooth section on the screw moves into the threaded cylinder, the screw stops moving, and the extension cylinder can continue to lengthen the vertical rod. S4. When the bracket needs to be removed, reverse the operating cylinder. The operating cylinder will drive the extension cylinder to retract, and the return spring will provide a continuous force to the screw, so that the screw and the threaded cylinder will continue to mesh. The threaded cylinder will drive the screw to move, so that the reinforcing plate will retract.

[0025] By adopting the above technical solution, the operating cylinder can be rotated, and the extension cylinder can be used to lengthen the vertical rod. At the same time, the reinforcing plate can also reinforce the support, making it easier for workers to operate and improving the problem of low installation efficiency of template support.

[0026] In summary, this application includes at least one of the following beneficial technical effects: 1. This application sets up an operating cylinder and an extension cylinder. When the ground is uneven, the operating cylinder is rotated, which drives the extension cylinder to move. The extension cylinder lengthens the vertical rod. When the extension cylinder contacts the ground, the operating cylinder stops rotating, thus completing the support of the template. This facilitates operation by workers and improves the problem of low installation efficiency of template support. 2. By setting up a reinforcing plate, the operating cylinder can drive the reinforcing plate to rotate through the transmission component during the movement of the extension cylinder, so that the reinforcing plate contacts the ground. The reinforcing plate can reinforce the support and further improve the stability of the support for the template. 3. This application, by setting up a threaded cylinder, a screw, and a transmission rod, allows the operating cylinder to drive the second gear to rotate during the movement of the extension cylinder. The second gear drives the first gear to rotate, the first gear drives the threaded cylinder to rotate, the threaded cylinder drives the screw to move, the screw drives the transmission rod to move, and the transmission rod drives the reinforcing plate to flip through a sliding component, so that the reinforcing plate contacts the ground, making it convenient for workers to operate.

[0032] The following is in conjunction with the appendix Figure 1-4 This application will be described in further detail.

[0033] This application discloses a formwork support for a tall load-bearing structure and its construction method. (Refer to...) Figure 1 and Figure 2 The tall load-bearing structure formwork support includes a formwork 1, a support 2, an extension component 3, and a reinforcing component 4. The support 2 includes multiple horizontal bars 21 and multiple vertical bars 22, which together form the support 2. The support 2 is fixedly connected to the bottom of the formwork 1. Multiple extension components 3 are provided and are corresponding to the vertical bars 22. The extension components 3 are installed on the vertical bars 22 and can extend the vertical bars 22. The reinforcing component 4 is installed on the extension components 3 and can reinforce the support 2.

[0034] Reference Figure 3 and Figure 4The extension component 3 includes an extension cylinder 31, an operating cylinder 32, and a load-bearing plate 33. The extension cylinder 31 is vertically sleeved on the bottom of the vertical rod 22, and the extension cylinder 31 is slidably connected to the vertical rod 22. A second sliding groove 221 is vertically formed on the outer circumferential surface of the vertical rod 22. A second slider 312 is fixedly connected to the inner wall of the extension cylinder 31. The second slider 312 is placed in the second sliding groove 221 and can move vertically along the second sliding groove 221. The extension cylinder 31 can extend from the bottom of the vertical rod 22, thereby lengthening the vertical rod 22. The operating cylinder 32 is sleeved on the vertical rod 22 and located above the extension cylinder 31. The bottom of the operating cylinder 32 is rotatably connected to the top of the extension cylinder 31. An internal thread is provided on the inner circumferential surface of the vertical rod 22, and an external thread is provided on the outer circumferential surface of the vertical rod 22. The internal thread on the operating cylinder 32 and the external thread on the vertical rod 22 are used to cooperate. When the operating cylinder 32 is rotated, the operating cylinder 32 drives the extension cylinder 31 to move. When the extension cylinder 31 contacts the ground, the operating cylinder 32 stops rotating, which facilitates operation by the staff and improves the problem of low installation efficiency of the template support. The load-bearing plate 33 is fixedly connected to the bottom of the extension cylinder 31 and is placed horizontally below the vertical rod 22. The operating cylinder 32 drives the load-bearing plate 33 to move, so that the load-bearing plate 33 contacts the ground, which increases the contact area between the extension cylinder 31 and the ground and improves the stability of the extension cylinder 31.

[0035] Reference Figure 1 and Figure 3 Multiple sets of reinforcing components 4 are provided, and these multiple sets of reinforcing components 4 are evenly distributed around the center of the extension cylinder 31. Each reinforcing component 4 includes a reinforcing plate 41 and multiple insert rods 42. The reinforcing plate 41 is hinged to the side wall of the load-bearing plate 33. A transmission component 5 is installed on the extension cylinder 31. Multiple sets of transmission components 5 are provided and are corresponding to the reinforcing components 4. The operating cylinder 32 can drive the reinforcing plate 41 to rotate through the transmission component 5, so that the reinforcing plate 41 contacts the ground. The reinforcing plate 41 can reinforce the support 2 and improve the stability of the support 2 in supporting the template 1. Multiple insert rods 42 are fixedly connected to the bottom of the reinforcing plate 41. The ends of the multiple insert rods 42 away from the reinforcing plate 41 are all tapered. The reinforcing plate 41 drives the multiple insert rods 42 to rotate, so that the multiple insert rods 42 are inserted into the ground, making the reinforcing plate 41 more stable.

[0036] Reference Figure 1 and Figure 3 A sliding component 6 is installed on the end face of the reinforcing plate 41. A first sliding groove 411 is provided on the end face of the reinforcing plate 41. The first sliding groove 411 is a dovetail groove. The sliding component 6 includes a first slider 61. The first slider 61 is a dovetail block. The first slider 61 is placed in the first sliding groove 411 and can slide along the first sliding groove 411.

[0037] An installation block 311 is fixedly connected to the side wall of the extension cylinder 31. The transmission component 5 includes a threaded cylinder 51, a screw 52, ​​a transmission rod 53, a limiting plate 54, and a return spring 55. The threaded cylinder 51 is rotatably mounted on the end face of the installation block 311 and is vertically arranged. A first gear 511 fixedly connected to the threaded cylinder 51 is sleeved on the threaded cylinder 51. A second gear 321 fixedly connected to the operating cylinder 32 is sleeved on the operating cylinder 32. The second gear 321 meshes with the first gear 511, and the operating cylinder 32 drives the second gear 521. Gear 321 rotates, and the second gear 321 drives the first gear 511 to rotate, which in turn drives the threaded cylinder 51 to rotate. The screw 52 is vertically inserted into the threaded cylinder 51 and threadedly connected to it. The threaded cylinder 51 drives the screw 52 to move. A transmission rod 53 is hinged to the circumferential surface at the bottom of the screw 52. The end of the transmission rod 53 away from the screw 52 is hinged to the first slider 61. The screw 52 drives the transmission rod 53 to move, and the transmission rod 53 drives the first slider 61 to move... The screw slides in the first groove 411, while the first slider 61 drives the reinforcing plate 41 to rotate, facilitating operation by the staff. The limiting plate 54 is fixedly connected to the top of the screw 52, ​​limiting the screw 52 and reducing the occurrence of the screw 52 disengaging from the threaded cylinder 51. The top of the screw 52 is provided with a smooth section. One end of the return spring 55 is fixedly connected to the bottom of the screw 52, ​​and the other end of the return spring 55 is fixedly connected to the mounting block 311. During the movement of the screw 52, ​​the return spring... Spring 55 is in a stretched state. When the smooth section on screw 52 moves into threaded cylinder 51, reinforcing plate 41 contacts the ground, screw 52 stops moving, and operating cylinder 32 can continue to rotate, so that extension cylinder 31 can continue to lengthen vertical rod 22. At the same time, return spring 55 provides continuous force to screw 52, ​​so that screw 52 and threaded cylinder 51 are continuously engaged. When it is necessary to remove bracket 2, operating cylinder 32 is reversed, threaded cylinder 51 drives screw 52 to move, so that reinforcing plate 41 is retracted.

[0038] The implementation principle of a tall load-bearing formwork support according to an embodiment of this application is as follows: When it is necessary to support the formwork 1, firstly, a support 2 is erected using multiple horizontal bars 21 and multiple vertical bars 22, and the formwork 1 is fixed to the support 2. Then, the operating cylinder 32 is rotated, which drives the extension cylinder 31 to move. The extension cylinder 31 drives the load-bearing plate 33 to move, so that the load-bearing plate 33 contacts the ground, thus completing the support of the formwork 1. This facilitates operation by workers and improves the problem of low installation efficiency of the formwork support. At the same time, the operating cylinder 32 drives the second gear 321 to rotate, which drives the first gear 511 to rotate. The first gear 511 drives the threaded cylinder 51 to rotate, which drives the screw 52 to move. The screw 52 drives the transmission rod 53 to move, which drives the reinforcing plate 41 to rotate, so that the reinforcing plate 41 contacts the ground. The reinforcing plate 41 can reinforce the support 2, further improving the stability of the support 2 in supporting the formwork 1.

[0039] When the bracket 2 needs to be removed, the operating cylinder 32 is reversed, which drives the extension cylinder 31 to retract. The return spring 55 provides a continuous force to the screw 52, ​​so that the screw 52 and the threaded cylinder 51 are continuously engaged. The threaded cylinder 51 drives the screw 52 to move, so that the reinforcing plate 41 is retracted, making it easier for the staff to operate.

[0040] A construction method for formwork supports for tall load-bearing structures includes the following steps: S1. First, use multiple horizontal bars 21 and multiple vertical bars 22 to build a support frame 2, and then fix the template 1 to the support frame 2.

[0041] S2. Then, the operating cylinder 32 is rotated, which drives the extension cylinder 31 to move. The extension cylinder 31 drives the load-bearing plate 33 to move, so that the load-bearing plate 33 contacts the ground. At the same time, the operating cylinder 32 drives the second gear 321 to rotate, which drives the first gear 511 to rotate. The first gear 511 drives the threaded cylinder 51 to rotate, which drives the screw 52 to move. The screw 52 drives the transmission rod 53 to move, and the transmission rod 53 drives the reinforcing plate 41 to flip.

[0042] S3. After the reinforcing plate 41 contacts the ground, the operating cylinder 32 continues to rotate. At this time, the smooth section on the screw 52 moves into the threaded cylinder 51, the screw 52 stops moving, and the extension cylinder 31 can continue to lengthen the vertical rod 22.

[0043] S4. When it is necessary to remove the bracket 2, reverse the operating cylinder 32. The operating cylinder 32 drives the extension cylinder 31 to retract, and the return spring 55 provides a continuous force to the screw 52, ​​so that the screw 52 and the threaded cylinder 51 are continuously engaged. The threaded cylinder 51 drives the screw 52 to move, so that the reinforcing plate 41 is retracted.

[0044] 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.
