Description

Technical Field

[0001] The invention relates to the field of building construction, and in particular to a tower-building machine for building a high-rise tower and a construction method thereof. Background Art

[0002] With the development of society, existing buildings have unique shapes. Innovative designs that could only remain on design drawings in the past are gradually appearing in real life. However, buildings with relatively novel shapes often have the problem of greater construction difficulty. For example, buildings with high cylindrical structures such as the Guangzhou Tower have the characteristics of high construction technology requirements, great difficulty, and high safety management risks. The invention patent with Chinese patent application number 202410914939.2 proposes a tower-building machine and a tower-building method, including a fixed frame, a support frame, a telescopic device, a suspension frame and a template, wherein the support frame includes an intermediate frame, a side frame and a telescopic frame, wherein the intermediate frame is arranged above the fixed frame, and the two are connected by the telescopic device; the side frames are arranged on both sides of the intermediate frame; the side frames are connected to the intermediate frame through the telescopic frame, and the length of the telescopic frame along the direction from the intermediate frame to the side frame is adjustable; a plurality of suspension frames are fixedly arranged on the bottom side of the side frame; and the template is fixedly arranged on the suspension frame. The invention sets a telescopic frame, and in the process of the tower-building machine building a special-shaped tower column with an outer diameter that decreases uniformly from bottom to top, by adjusting the length of the telescopic frame, only the installation angle of the template needs to be adjusted once, which simplifies the construction process of the tower-building machine, thereby improving the construction efficiency of the tower-building machine. The technical solution proposed in the above invention is mainly aimed at improving the telescopic frame of the tower-building crane, so as to achieve a single adjustment of the template installation angle and thus simplify the process and improve efficiency. However, when the tower to be built is a side curved type building similar to the shape of the Guangzhou Tower, its side is similar to a "small waist" structure. Therefore, the conventional tower-building crane needs to continuously adjust the construction "aperture" during operation to meet the construction needs. On the one hand, it is time-consuming and labor-intensive, and on the other hand, it has high requirements on the structure. At the same time, it is difficult to achieve the functions of lightweight, self-lifting, and easy disassembly. Summary of the invention

[0003] Therefore, in order to solve the above problems, the present invention proposes a tower-building machine for building a tall tower and a construction method thereof, which solves the technical problem that the existing tower-building machine is difficult to adapt to the construction of the curved outer surface of the tower body when carrying out unconventional tower construction.

[0004] To achieve the above object, the present invention adopts the following technical solutions: A tower crane for constructing a high-rise tower includes a machine position support system, a hydraulic power climbing system, a control system, and a top steel platform system. The machine position support system provides the main support function. The hydraulic power climbing system is sleeved on the machine position support system and moves up and down along the length direction of the machine position support system. The top steel platform system is arranged at the top of the machine position support system. The control system is used to control the power driving components in each system. The machine position support system includes a central support scaffold and several edge support scaffolds. The hydraulic power climbing system includes an annular support grid and a first lifting cage arranged around the annular support grid. The top steel platform system includes a circular construction grid and a second lifting cage arranged on the circular construction grid. The second lifting cage is arranged around the outer edge of the circular construction grid. Hydraulic lifters are arranged in both the first lifting cage and the second lifting cage. The lifting and lowering of the annular support grid and the rising of the circular construction grid are controlled by the hydraulic lifters. An activity working platform for external construction of the building is movably arranged on the annular support grid. During the construction process, the activity working platform is adjusted adaptively according to the outer wall diameter.

[0005] Furthermore, each of the edge support scaffolds is evenly arranged around the central support scaffold, and the circumferential distance between adjacent two edge support scaffolds is the same.

[0006] Furthermore, the first lifting cage is fixedly connected to the annular support grid. The activity working platform moves horizontally in parallel and approaches or moves away from the building through a hydraulic push rod. During the construction of the building exterior wall, the activity working platform always abuts against the building exterior wall. A mobile support device is arranged on the activity working platform.

[0007] Furthermore, the mobile support device includes a fixed sleeve cage arranged at the end of the free end of the activity working platform, a transfer gear arranged in the fixed sleeve cage, a first auxiliary support plate and a second auxiliary support plate arranged in the fixed sleeve cage. A transmission cavity is arranged in the fixed sleeve cage, and the transmission cavity is parallel to the horizontal plane. The first auxiliary support plate is arranged in the transmission cavity and displaces in the transmission cavity, and the stroke is limited by the transmission cavity. First meshing teeth are arranged on the first auxiliary support plate. The first auxiliary support plate is meshed and connected to the transfer gear through the first meshing teeth. The second auxiliary support plate is fixedly connected to the transfer gear and deflects following the rotation of the transfer gear. The rotation mode of the transfer gear includes being driven to rotate by the first meshing teeth on the first auxiliary support plate and being driven to rotate by a rotary motor.

[0008] Furthermore, the second auxiliary support plate is provided with connecting rods, the connecting rods are fixedly arranged on both sides of the second auxiliary support plate, and the second auxiliary support plate is fixedly connected to the transfer gear through the connecting rods.

[0009] Furthermore, a first elastic support device is provided at the free end of the first auxiliary support plate, and when the first auxiliary support plate is against the outer surface of the building, the first elastic support device provides a reverse thrust for the first auxiliary support plate.

[0010] Furthermore, the first elastic support device includes a plurality of elastic support rods. In an initial state, the elastic support rods are in the same horizontal plane, and the elastic support rods work independently, retract inwards when subjected to force, and pop outwards when the force is lost.

[0011] Furthermore, a second elastic support device is provided at the free end of the second auxiliary support plate, and the second elastic support device includes a circular support protrusion and a pressure sensor arranged in the circular support protrusion, and the circular support protrusion elastically expands and contracts when subjected to force; in an unstressed state, the height of the pressure sensor is lower than the height of the convex edge of the circular support protrusion, and the pressure sensor is connected to the switch of the hydraulic push rod.

[0012] A construction method for a tower crane for building a high tower comprises the following steps: S1. Pre-buried machine support system; after the basement structure is completed, install the external protection rack, carry out the upper main structure construction, and install the machine support system at the same time; S2, installation of hydraulic power climbing system; connecting the first lifting cage in the hydraulic power system and the edge support scaffold in the machine support system by mutually sleeved; S3, installation of top steel platform system: the top steel platform system is installed when the main structure of the building is constructed to the third floor, the top steel platform system and the machine support system are assembled, the second lifting cage and the central support scaffolding and edge support scaffolding are installed, and the whole tower crane is tested at the same time; S4, wall-attached installation: As the top steel platform system continues to rise, it is installed on the wall between the building; S5, exterior wall construction; the hydraulic power climbing system rises along with the top steel platform system. After the main building is completed, the hydraulic power climbing system descends and the exterior wall construction of the building is carried out from top to bottom; S6. Completed disassembly: Use the tower crane to dismantle the top steel platform system, machine support system, and hydraulic power climbing system.

[0013] Furthermore, in step S5, during the exterior wall construction process, the movable working platform in the hydraulic climbing system is pushed outward by the action of the hydraulic push rod, approaches the exterior wall of the building and establishes a connection with the exterior wall of the building. As the hydraulic climbing system rises and falls, the movable working platform is reconnected with the exterior wall of the building, and each first elastic support rod independently extends and contracts to fit the curved surface of the exterior wall of the building.

[0014] By adopting the above technical solution, the beneficial effects of the present invention are: 1. The present invention solves the technical problem that the existing tower construction machine is difficult to adapt to the construction of the curved outer surface of the tower body when carrying out unconventional tower construction through the mutual cooperation of the machine support system, the hydraulic power climbing system, the control system and the top steel platform system. The hydraulic power climbing system and the top steel platform system are respectively lifted up and down by the first lifting cage and the second lifting cage to construct the tower building; the work efficiency is improved. At the same time, the machine support system adopts the cooperation mode of the central support scaffolding and the edge support scaffolding. The edge support scaffolding is arranged around the central support scaffolding, which is more suitable for the construction of the cylindrical tower.

[0015] 2. Conventional tower construction machines are usually only suitable for cylindrical towers with low heights during construction. Facing the curved "waist" design with high height, its movable working platform is difficult to adapt to the curved side of the tower building in real time and thus achieve a stable fit with the tower building. If the movable working platform and the building are not stably matched, it is difficult to carry out efficient construction. At the same time, there are risks for construction workers during the exterior wall construction process. Therefore, when encountering buildings with curved exterior walls, the industry generally adopts the overall replacement of the annular support grid or the addition of an extension plate between the movable working platform and the tower building. Both of the above methods have disadvantages, specifically: the exterior wall construction emphasizes continuity, and the annular support grid is frequently replaced during the construction process. On the one hand, the grid is time-consuming and labor-intensive, and on the other hand, it is difficult to ensure construction continuity. If an extension plate is set on the movable working platform, it is difficult to ensure the connection stability between the extension plate and the outer wall of the building, and the extension plate is an additional component, and its connection integrity with the movable working platform is slightly poor, which is prone to risks during the construction process. The present invention, on the other hand, is provided with a mobile support device on the movable working platform, and the connection relationship between the movable working platform and the outer wall of the building is adjusted by the mobile support device to achieve real-time close fitting connection. At the same time, the mobile support device can provide the movable working platform with stronger support stability, thereby ensuring that the movable working platform can have a greater load-bearing performance, thereby being able to prevent more materials at a single time, thereby improving work efficiency.

[0016] 3. The advantages of the mobile support device in the present invention are reflected in that it achieves the expected purpose through the mutual cooperation of the first auxiliary support plate and the second auxiliary support plate. Specifically, the first auxiliary support plate, as the main support plate, connects the movable working platform and the building exterior wall, and abuts against the building exterior wall through telescopic extension. For tower buildings with different outer diameters and continuously changing heights, the first auxiliary support plate can always abut against the building exterior wall and cooperate stably with it. When the first auxiliary support plate abuts against the building exterior wall, the second auxiliary support plate is simultaneously flipped to abut against the building exterior wall in an inclined state, ensuring that the first auxiliary support plate, the second auxiliary support plate, and the building exterior wall together form a triangular stable structure. At the same time, this triangular stable structure is different from the traditional support frame structure in the following aspects: A first elastic device is provided at the end of the free end of the first auxiliary support plate, which can closely fit the arc-shaped wall surface of the building exterior wall. When the hydraulic push rod pushes the movable working platform outwards until the first auxiliary support plate abuts against the building exterior wall, it continues to push outwards until the second auxiliary support plate also abuts against the building exterior wall. When the pressure sensor on the second auxiliary support plate reaches the preset value, the switch of the hydraulic push rod is controlled to stop the hydraulic push rod from working. Although the hydraulic push rod stops working at this time, the end of the free end of the first auxiliary support plate is still under the elastic force of the first elastic support device and will not become loose from the building exterior wall, and there is an interaction force between the two. The end of the free end of the second auxiliary support plate will also not become loose from the building exterior wall under the elastic force of the second elastic support device, and there is also an interaction force between the two.

[0017] 4. At the same time, in the process of the movable working platform of the present invention being pushed outwards until the first auxiliary support plate abuts against the wall surface of the building exterior wall, the transfer gear does not rotate actively. Only when it is necessary to disconnect the connection with the building exterior wall, the first auxiliary support plate is driven to retract inwards by rotating the motor.

[0018] 5. In the construction method adopted by the present invention, through the adaptive matching connection to the building exterior wall in step S5, the arc-shaped fitting of the building exterior wall is achieved by the independent telescoping of each first elastic support rod, ensuring the tightness of the cooperation and stronger integrity.
