Description

Technical Field

[0001] The invention relates to the technical field of building construction, and in particular to a dismantling and modification structure and method of a climbing formwork platform installed on a super-high-rise cantilever truss column. Background Art

[0002] At present, all super high-rise buildings in my country are equipped with refuge floors. After the core tube of the refuge floor is cast, the outer frame needs to be supported by cantilever truss columns to ensure the integrity and stability of the outer frame of the refuge floor. However, since the size of the climbing formwork used in the casting process of the core tube of the super high-rise building is all expanded around the outer periphery of the core tube, conflicts between the column corbels and the climbing formwork will occur during the installation of the cantilever truss columns, resulting in the need to dismantle the four corners of the five-story climbing formwork platform to ensure climbing. This method will lead to the destruction of the integrity of the climbing formwork, and the restoration of the climbing formwork platform after dismantling and modification will waste a lot of manpower, material resources and construction period. It is urgent to study a method for dismantling and modifying a climbing formwork platform that cooperates with the installation of super high-rise cantilever truss columns. Summary of the invention

[0003] In view of the deficiencies in the prior art, the present invention develops a dismantling and modification structure and method for a climbing formwork platform for installing a super-high-rise cantilever truss column. The structure has convenient dismantling and installation, good stability, and only takes 1-2 hours to dismantle and modify, thus saving construction time.

[0004] The technical solution to the technical problem of the present invention is: a method for dismantling and modifying a climbing formwork platform installed on a super-high-rise outrigger truss column, comprising the following steps: Step 1: At the standard level, cut off the four corners of the climbing surface, punch holes in the sub-platform board and set two pins at the bottom to fix the roller support frame; Step 2: Punch holes in the mother platform plate and set guide rails on the top; Step 3: Place the roller on the guide rail and connect the roller support frame to the roller and the sub-platform board; Step 4: Drill holes on the mother platform plate and the sub-platform plate, matching the hole positions with the holes on the fixing block, and temporarily fix the sub-platform plate to the fixing block by bolts; Step 5: When the outrigger truss needs to be installed, open the fixing block, lift the sub-platform plate upwards and push the sub-platform plate in the direction of the guide rail until the roller enters the roller hole; Step 6: After the climbing platform is finished climbing, pull the sub-platform board in the initial direction of the sub-platform board, then install the fixing block to restore the initial state to ensure the stability of the platform.

[0005] Preferably, the direction in which the guide rail is set in step 2 is parallel to the line connecting the holes punched on the mother platform plate and the sub-platform plate.

[0006] Preferably, in step 3, the roller support frame is rotationally connected to the roller and the sub-platform plate.

[0007] Preferably, during the process of opening the sub-platform plate in step 4, facade protection must be provided around it until the cantilever truss is installed.

[0008] A climbing formwork platform for installing a super-high-rise cantilever truss column comprises a mother platform plate, a sub-platform plate and a fixed block, wherein the mother platform plate is provided with a guide rail, the guide rail is provided with a roller, the roller is rotatably connected to a rolling support frame, and the other end of the roller support frame is rotatably connected to the sub-platform plate.

[0009] Preferably, the mother platform plate and the sub-platform plate are temporarily fixed by fixing block bolts.

[0010] Preferably, a roller hole is provided on the end of the mother platform plate in the length direction of the guide rail away from the sub-platform plate.

The main platform plate and the sub-platform plate are temporarily fixed by fixing blocks and bolts. After the climbing formwork platform is completed, the sub-platform plate can be restored to its initial state and remain stable, ensuring the structural stability of the entire platform; 4. The rotating connection between the roller support frame, the roller and the sub-platform makes the sub-platform more flexible during movement and convenient for various operations; 5.

[0014] In order to clearly illustrate the technical features of the present invention, the present invention is described in detail below through specific implementation methods and in conjunction with the accompanying drawings.

[0015] Example 1 See also Figures 1 to 4 A method for dismantling and modifying a climbing formwork platform installed with an 8-column super-high-rise outrigger truss comprises the following steps: Step 1: At the standard layer, cut off the four corners of the climbing touch, punch holes in the sub-platform plate 2 and set two pins at the bottom to fix the roller 5 support frame; Step 2: Punch holes in the mother platform plate 1 and set a guide rail 4 on the upper part; Step 3: Place the roller 5 on the guide rail 4, and connect the roller 5 support frame to the roller 5 and the sub-platform plate 2; Step 4: Drill holes on the mother platform plate 1 and the sub-platform plate 2, the hole positions match the hole positions on the fixing block 6, and temporarily fix the sub-platform plate 2 to the fixing block 6 by bolts; Step 5: When the outrigger truss 8 needs to be installed, open the fixing block 6, lift the sub-platform board 2 upward and push the sub-platform board 2 in the direction of the guide rail 4 until the roller 5 enters the roller 5 hole 3; Step 6: After the climbing platform is finished climbing, pull the sub-platform board 2 in the initial direction of the sub-platform board 2, and then install the fixing block 6 to restore the initial state to ensure the stability of the platform.

[0016] In step 2, the direction in which the guide rail 4 is arranged is parallel to the connecting line of the holes punched on the mother platform plate 1 and the sub-platform plate 2 .

[0017] In step 3, the roller 5 support frame is rotatably connected to the roller 5 and the sub-platform plate 2.

[0018] During the opening process of the sub-platform plate 2 in step 4, the surrounding surface must be protected until the cantilever truss 8 is installed.

[0019] A climbing formwork platform installed with 8 columns of a super high-rise cantilever truss comprises a mother platform plate 1, a sub-platform plate 2 and a fixing block 6, the mother platform plate 1 is provided with a guide rail 4, the guide rail 4 is provided with a roller 5, the roller 5 is rotatably connected with a rolling support frame, and the other end of the roller 5 support frame is rotatably connected with the sub-platform plate 2; the mother platform plate 1 and the sub-platform plate 2 are temporarily fixed by the fixing block 6 and bolts; a roller 5 hole 3 is provided at one end of the guide rail 4 on the mother platform plate 1 which is away from the sub-platform plate 2 in the length direction.

[0020] Principle and specific operation process Aiming at the problem that the climbing formwork platform must be inevitably cut off when encountering a floor where an outrigger truss 8 columns are installed during the construction of a super high-rise building in the prior art, the present invention proposes a structure and method for dismantling and modifying a climbing formwork platform installed with an outrigger truss 8 columns: When the standard layer is used, the platforms at the four corners of the climbing formwork are cut off, holes are punched in the sub-platform board 2 to be removed, and two pins are set at the bottom to fix the roller 5 support frame. The sub-platform board 2 can rotate around the pins, which is convenient for movement in subsequent steps. At the same time, the pins can provide stable support for the roller 5 to ensure the stability of the sub-platform board 2 during movement.

[0021] The mother platform plate 1 is punched, and a guide rail 4 is arranged on the upper part. The setting direction of the guide rail 4 is parallel to the connecting line of the holes punched on the mother platform plate 1 and the sub-platform plate 2. It is ensured that the sub-platform plate 2 can slide along the direction of the guide rail 4 during the movement, providing a guide for the movement of the sub-platform plate 2. The roller 5 is placed on the guide rail 4, and the roller 5 support frame is rotatably connected between the roller 5 and the sub-platform plate 2. The sub-platform plate 2 can move along the guide rail 4 driven by the roller 5, and the angle of the sub-platform plate 2 can be flexibly adjusted during the movement. A roller 5 hole 3 is arranged at one end of the guide rail 4 on the mother platform plate 1 that is away from the sub-platform plate 2 in the length direction. The position and size design of the roller 5 hole 3 match the roller 5, ensuring that the sub-platform plate 2 can be accurately positioned to the specified position during the movement. When the sub-platform plate 2 needs to be moved to a specific position, the roller 5 support frame can adjust the angle of the sub-platform plate 2 according to the actual situation to ensure that the sub-platform plate 2 smoothly enters the roller 5 hole 3.

[0022] Holes are punched on the mother platform board 1 and the sub-platform board 2, the positions of the holes match the positions of the holes on the fixing block 6, and the sub-platform board 2 is temporarily fixed by bolts connected to the fixing block 6. This allows the sub-platform board 2 to remain stable when it does not need to be moved, and the fixing block 6 can be easily opened for operation when it needs to be moved.

[0023] When the cantilever truss 8 needs to be installed, open the fixing block 6, lift the sub-platform board 2 upwards and push the sub-platform board 2 in the direction of the guide rail 4 until the roller 5 enters the roller 5 hole 3. During the pushing process of the sub-platform board 2, the roller 5 rolls along the guide rail 4 until the roller 5 enters the roller 5 hole 3. The position and size design of the roller 5 hole 3 match the roller 5 to ensure that the sub-platform board 2 can be accurately positioned at the specified position. After the climbing formwork platform completes the climbing, pull the sub-platform board 2 in the initial direction of the sub-platform board 2, and then install the fixing block 6 to restore the initial state.

[0024] The sub-platform board 2 is connected to the roller 5 through the roller 5 support frame, and this connection mode enables the sub-platform board 2 to move on the mother platform board 1. The structural design of the sub-platform board 2 matches the mother platform board 1 to ensure that the sub-platform board 2 can remain stable during movement.

[0025] Although the above describes the specific implementation mode of the present invention in conjunction with the accompanying drawings, it is not intended to limit the scope of protection of the present invention. Based on the technical solution of the present invention, various modifications or variations that can be made by those skilled in the art without creative work are still within the scope of protection of the present invention.
