[0002] During the pouring and construction of bridge cylindrical piers, it is necessary to set up a working platform on the formwork to facilitate the operation of construction personnel.

[0003] Existing bridge cylindrical pier construction platforms, such as the one authorized by CN 210766416 U, have a construction platform that surrounds the template and can move up and down. However, the dimensions of the construction platform are fixed, making it unusable when the dimensions of the bridge cylindrical pier change. Summary of the Invention

[0004] The purpose of this invention is to provide a construction platform for bridge cylindrical piers, which can change the length of the movable plate and connecting rod, as well as the number of support rods, as needed to build a stable construction platform of different sizes.

[0005] To achieve these objectives and other advantages of the present invention, a bridge cylindrical pier construction platform is provided, comprising:

[0006] The template is fitted over the cylindrical pier, and the front, back, left and right sides of the template are provided with first T-shaped groove guide rails in the vertical direction;

[0007] Four supports, each set vertically, each with a second T-shaped groove guide rail set vertically; the four supports are respectively opposite to the four first T-shaped groove guide rails, and the second T-shaped groove guide rails on them are respectively opposite to the first T-shaped groove guide rails.

[0008] There are four movable plates, each corresponding to a first T-shaped groove guide rail and a second T-shaped groove guide rail. Each movable plate is a telescopic plate and is composed of multiple plate sections. Each movable plate has a T-shaped slider at both ends. The two sliders on each movable plate are located in the first T-shaped groove guide rail and the second T-shaped groove guide rail respectively, and can move up and down in the first T-shaped groove guide rail and the second T-shaped groove guide rail respectively under the drive of power.

[0009] Multiple support rods are placed on the four movable plates. Each support rod is ring-shaped with its center located on the axis of the template. The four outermost plates are fixedly connected to the support rods on them, and the innermost support rod is close to the template.

[0010] Multiple limiting blocks are provided. Except for the support rods on the outermost plates, there are four limiting blocks between each of the other support rods and their adjacent support rods. The four limiting blocks are located on the four movable plates respectively.

[0011] The four connecting rods correspond to the four movable plates respectively. Each connecting rod is a telescopic rod. Each connecting rod passes through the multiple support rods and the limiting blocks on the corresponding movable plate, and its two ends are respectively connected to the two sliders on the corresponding movable plate.

[0012] Preferably, in the bridge cylindrical pier construction platform, each connecting rod consists of two rods. The four outer rods do not pass through the multiple support rods and the corresponding limiting blocks on the moving plate, while the four inner rods pass through the multiple support rods and the corresponding limiting blocks on the moving plate.

[0013] Preferably, in the bridge cylindrical pier construction platform, each connecting rod has external threads at both ends, each slider has a corresponding threaded hole, and each connecting rod is inserted into the threaded holes of its two corresponding sliders and is threadedly connected to its two corresponding sliders.

[0014] Preferably, in the bridge cylindrical pier construction platform, for any connecting rod, the outermost rod can be inserted into the innermost rod, and the distance between each support and the outermost support rod is greater than the length of the innermost rod.

[0015] Preferably, the bridge cylindrical pier construction platform further includes:

[0016] A connecting plate is fixed to two opposite supports among the four supports, and a fixing plate is provided at each end of the connecting plate;

[0017] A rotating shaft is rotatably connected to both fixed plates, and one end of the rotating shaft rotates under the drive of a power device.

[0018] Four ropes, one end of which is fixed to the rotating shaft, and the other end of which is fixed to the four sliders below the connecting plate.

[0019] Preferably, in the bridge column pier construction platform, the bottom of the innermost support rod is provided with multiple threaded holes at intervals, and the bridge column pier construction platform further includes:

[0020] Multiple support plates, each of which is a telescopic plate, are used. Each support rod rests on its respective support plate. One end of each support plate is fixedly connected to the outermost support rod, and the other end is provided with a threaded hole. The threaded holes on each support plate correspond one-to-one with the threaded holes on the innermost support rod, and bolts are inserted between the threaded holes on each support plate and the corresponding threaded holes on the innermost support rod.

[0021] Preferably, in the bridge cylindrical pier construction platform, a fence is provided around the outermost support rod along its circumferential direction.

[0022] The present invention has at least the following beneficial effects:

[0023] This invention allows for the modification of the lengths of the movable plate and connecting rods, as well as the number of support rods, to construct stable construction platforms of varying sizes. By changing the length of the movable plate, the sliders at both ends are inserted into their corresponding first and second T-slot guide rails, preventing horizontal movement at both ends and thus stably supporting the support rods. Similarly, by changing the length of the connecting rods, both ends are connected to their corresponding sliders on the movable plate, preventing horizontal movement at both ends and thus preventing relative movement between the limiting blocks and the two support rods located on either side of each limiting block.

[0024] This invention uses a power device to drive a rotating shaft, which enables ropes to be pulled upwards or lowered to the construction platform. Therefore, there is no need to build scaffolding or climbing stairs during construction, thus saving construction materials, reducing labor, and shortening the construction period.

[0025] Other advantages, objectives and features of the present invention will become apparent in part from the following description, and in part from those skilled in the art through study and practice of the invention. Attached Figure Description

[0028] The present invention will now be described in further detail with reference to the accompanying drawings, so that those skilled in the art can implement it based on the description.

[0029] It should be noted that in the description of this invention, the terms "lateral", "longitudinal", "up", "down", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", and "outer" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this invention.

[0030] As shown in Figures 1 and 2, the present invention provides a bridge cylindrical pier construction platform, comprising:

[0031] Template 1 is fitted over the cylindrical pier. The front, back, left and right sides of template 1 are provided with first T-shaped groove guide rails in the vertical direction. The four first T-shaped groove guide rails are arranged at 90-degree intervals along the circumferential direction of template 1.

[0032] Four supports 2, each of which is vertically arranged, and each of which has a second T-shaped groove guide rail arranged vertically; the four supports 2 are respectively opposite to the four first T-shaped groove guide rails, and the second T-shaped groove guide rails on them are respectively opposite to the first T-shaped groove guide rails.

[0033] Four movable plates 3, each corresponding to a first T-shaped groove guide rail and a second T-shaped groove guide rail. Each movable plate 3 is a telescopic plate composed of multiple plate sections. Each movable plate 3 has a T-shaped slider at both ends. The two sliders on each movable plate 3 are respectively located in the corresponding first T-shaped groove guide rail and second T-shaped groove guide rail, and their dimensions are matched with the first T-shaped groove guide rail and second T-shaped groove guide rail, respectively. They can move up and down in the first T-shaped groove guide rail and second T-shaped groove guide rail under the drive of power. After changing the length of the movable plate 3, the sliders at both ends of the movable plate 3 are inserted into the corresponding first T-shaped groove guide rail and second T-shaped groove guide rail, respectively, so that the two ends of the movable plate 3 cannot move in the horizontal direction, thereby making the movable plate 3 stably support each support rod 4.

[0034] Multiple support rods 4 are placed on the four movable plates 3. Each support rod 4 is ring-shaped with its center located on the axis of the template 1. The four outermost plates are fixedly connected to each of the support rods 4 on them, and the innermost support rod 4 is close to the template 1. Each support rod 4 on the four outermost plates is fixed to the four outermost plates. This part of the support rod 4 cannot be removed and can prevent the other support rods 4 inside from moving off-center.

[0035] Multiple limiting blocks 5 are provided. Except for the support rods 4 located on the outermost plates, four limiting blocks 5 are provided between each of the other support rods 4 and their adjacent support rods 4. The four limiting blocks 5 are located on the four movable plates 3 respectively. As shown in Figure 1, there are five support rods 4. The movable plate 3 is composed of two plates. The three support rods 4 located on the outermost plates are fixed to the outermost plates. Four limiting blocks 5 are provided between the fourth support rod 4 from the outside to the inside and the third support rod 4 from the outside to the inside. The four limiting blocks 5 are distributed on the four movable plates 3. This can prevent the fourth support rod 4 from moving relative to the third support rod 4 from the outside to the inside. Similarly, four limiting blocks 5 are provided between the innermost support rod 4 and the fourth support rod 4 from the outside to the inside. The four limiting blocks 5 are distributed on the four movable plates 3. This can prevent the innermost support rod 4 from moving relative to the fourth support rod 4 from the outside to the inside. By setting the limit block 5, the movement of each support rod 4 in the horizontal direction can be prevented.

[0036] Four connecting rods 6 correspond to four movable plates 3, each connecting rod 6 being a telescopic rod. Each connecting rod 6 passes through the multiple support rods 4 and each limiting block 5 on its corresponding movable plate 3, and its two ends are respectively connected to two sliders on its corresponding movable plate 3. By setting the connecting rods 6, the limiting block 5 can be fixed between its two corresponding support rods 4.

[0037] The bridge cylindrical pier construction platform provided in this solution involves placing template 1 over the cylindrical pier, and vertically setting T-shaped first T-slot guide rails on the front, back, left, and right sides of template 1. Four supports 2 are set corresponding to the four first T-slot guide rails, and a second T-slot guide rail is set on each of the four supports 2.

[0038] Based on the size of template 1, determine the number of support rods 4 and the length of the moving plate 3. Fix the four outermost plates to each of the support rods 4. Place the remaining support rods 4 on the moving plate 3 and set four limiting blocks 5 between the remaining support rods 4 and their adjacent support rods 4. Position the four limiting blocks 5 on the four moving plates 3. Then, make each connecting rod 6 pass through multiple support rods 4 and the corresponding limiting blocks 5 on the moving plate 3, and connect its two ends to the two sliders on the corresponding moving plate 3. Finally, hoist the construction platform so that the sliders at both ends of the four moving plates 3 are inserted into the corresponding first T-shaped groove guide rail and second T-shaped groove guide rail. The construction platform can then move up and down under the drive of power.

[0039] When the construction platform needs to be applied to the construction of the next bridge column pier, the construction platform is moved upward until the sliders at both ends of each movable plate 3 disengage from the corresponding first T-slot guide rail and second T-slot guide rail. Then the construction platform is placed on the ground, and then each connecting rod 6 is removed. This process is repeated continuously.

[0040] In another embodiment, in the bridge cylindrical pier construction platform, each connecting rod 6 consists of two rods. The four outer rods do not pass through the multiple support rods 4 and the corresponding limiting blocks 5 on the moving plate 3, while the four inner rods pass through the multiple support rods 4 and the corresponding limiting blocks 5 on the moving plate 3.

[0041] In another embodiment, in the bridge cylindrical pier construction platform, each connecting rod 6 has external threads at both ends, and each slider has corresponding threaded holes. Each end of the connecting rod 6 is inserted into the threaded holes of its two corresponding sliders and is threadedly connected to them. This facilitates fixing the ends of the connecting rod 6 to the two sliders and also makes it easy to remove the connecting rod 6.

[0042] In another embodiment, in the bridge cylindrical pier construction platform, for any connecting rod 6, the outer rod can be inserted into the inner rod, and the distance between each bracket 2 and the outermost support rod 4 is greater than the length of the inner rod.

[0043] When the connecting rod 6 passes through the multiple support rods 4 and the corresponding limiting blocks 5 on the moving plate 3, the outer rod is inserted into the inner rod, and the connecting rod 6 is positioned between the bracket 2 and the outermost support rod 4. Then, one end of the outer rod is connected to the corresponding slider, and one end of the inner rod passes through the multiple support rods 4 and the corresponding limiting blocks 5 on the moving plate 3 and is connected to the corresponding slider.

[0044] In another embodiment, the bridge cylindrical pier construction platform further includes:

[0045] The connecting plate 7 is fixed on two opposite supports 2 of the four supports 2, and a fixing plate 701 is provided at each end of the connecting plate 7;

[0046] The rotating shaft 8 is rotatably connected to both fixed plates 701, and one end of the rotating shaft 8 rotates under the drive of the power device.

[0047] Four ropes 9, one end of which is fixed to the rotating shaft 8, and the other end of which is fixed to the four sliders below the connecting plate 7.

[0048] The rotating shaft 8 is driven by a power device, which can pull the rope 9 up or lower the construction platform. Therefore, there is no need to build scaffolding or climbing stairs during construction, which saves construction materials, labor, and shortens the construction period.

[0049] In another embodiment, the bridge column pier construction platform has multiple threaded holes spaced apart at the bottom of the innermost support rod 4. The bridge column pier construction platform also includes:

[0050] Multiple support plates 10, each of which is a telescopic plate, are provided. Each support rod 4 rests on each support plate 10. One end of each support plate 10 is fixedly connected to the outermost support rod 4, and the other end is close to the template 1. Each support plate 10 has a threaded hole. The threaded holes on each support plate 10 correspond one-to-one with the threaded holes on the innermost support rod 4. Bolts are inserted between the threaded holes on each support plate 10 and the threaded holes on the corresponding innermost support rod 4.

[0051] After placing all the support rods 4 and limit blocks 5 on the four movable plates 3, adjust the length of the support plate 10 so that the threaded holes on each support plate 10 correspond one-to-one with the threaded holes on the innermost support rod 4. Then, insert bolts into each support plate 10 so that it supports each support rod 4 while preventing the length of the support plate 10 from changing.

[0052] In another embodiment, the bridge cylindrical pier construction platform has a surrounding fence installed on the outermost support rod 4 along its circumferential direction.

[0053] Although embodiments of the present invention have been disclosed above, they are not limited to the applications listed in the specification and embodiments. They can be applied to various fields suitable for the present invention. For those skilled in the art, other modifications can be easily made. Therefore, without departing from the general concept defined by the claims and their equivalents, the present invention is not limited to the specific details and illustrations shown and described herein.
