Description

Technical Field

[0001] This invention relates to a device and method for tower cranes used in the construction of super high-rise buildings to pass through climbing scaffolding attached to walls, belonging to the technical field of building construction. Background Technology

[0002] With societal development, the construction industry is growing rapidly, and buildings are becoming increasingly tall. Tower cranes are commonly used for the vertical transport of materials needed during construction. A tower crane, also known as a tower hoist, is a rotating crane with a jib mounted on a tall tower. Since tower cranes operate in high-rise construction environments, when the tower exceeds its independent height, it must be fitted with wall ties attached to the building walls. This is because excessively tall tower cranes are highly unstable, and reinforcement is necessary to enhance their stability. However, the installation of wall ties must adhere to the tower crane's specifications. The spacing of the wall ties and the length of the free height above the attachment point cannot be arbitrarily exceeded, and any excessively long wall ties must undergo strength and stability calculations.

[0003] Climbing scaffolding is a new type of scaffolding system in the modern construction industry. It utilizes various forms of frame structures and auxiliary support structures, and is installed on the exterior walls of buildings to lift and transport materials needed during construction. Depending on the lifting method, climbing scaffolding can be divided into self-elevating, mutual-elevating, and integral-elevating types. The lifting movement of self-elevating climbing scaffolding is mainly achieved manually or electrically by alternating chains resting on the movable and fixed frames of the machine. From the overall structure of the climbing scaffolding, the movable and fixed frames can move up and down relative to each other. When the climbing scaffolding stops lifting, the movable and fixed frames are fixed to the wall with wall bolts for stability, and there is no relative movement between the frames. When it is necessary to lift the climbing scaffolding, one of the movable and fixed frames remains fixed to the wall, and the other frame is lifted using a chain hoist. The climbing principle of self-elevating climbing scaffolding is to alternately hang the movable and fixed frames on the wall, causing them to rise and fall relative to each other, thus propelling the climbing scaffolding up and down layer by layer along the pre-drilled holes in the exterior wall.

[0004] However, during the construction of some high-rise buildings, the location of the wall-mounted components connecting the tower crane to the building wall often conflicts with the location of the climbing scaffolding. Specifically, the wall-mounted components are fixedly connected between the building wall and the tower crane. However, the climbing scaffolding needs to move up and down along the building's exterior wall during use, which prevents the climbing scaffolding from being installed and used properly, thus significantly impacting the on-site construction progress. Therefore, there is an urgent need for a solution to the construction problem of the climbing scaffolding encountering the tower crane's wall-mounted components. Summary of the Invention

[0005] The summary section of this application is intended to provide a brief overview of the concepts, which will be described in detail in the detailed description section below. This summary section is not intended to identify key or essential features of the claimed technical solutions, nor is it intended to limit the scope of the claimed technical solutions.

[0006] To address the problems and shortcomings of existing technologies, this invention aims to provide a device and method for navigating tower cranes encountering climbing scaffolding during high-rise building construction. This involves disconnecting the external climbing scaffolding at the location of the tower crane's wall attachment and installing a sliding mesh frame protective screen on the inner side of the disconnection point. When the external climbing scaffolding encounters the tower crane's wall attachment during its ascent, the mesh frame protective screen is simply opened to complete normal ascent, and then slid back to the disconnection point for protection. This ensures edge protection for floors during construction while improving construction efficiency and saving time, thus solving the problems mentioned in the background art.

[0007] To achieve the above objectives, the present invention provides the following technical solution: This invention provides a device for tower cranes to pass through climbing scaffolding attached to walls in ultra-high-rise buildings. The device includes a main building structure and multiple supporting sliding rails. The external climbing scaffolding at the location where the tower crane is attached to the wall is disconnected from the main building structure. The multiple supporting sliding rails are vertically connected to the left and right ends of the floor slab outside the disconnection point via suspension beams. Multiple movable sliding rail units are horizontally connected across the supporting sliding rails. Each movable sliding unit includes an upper fixed rail and a lower fixed rail. The upper fixed rail spans between the multiple supporting sliding rails, and the lower fixed rail spans between the multiple supporting sliding rails via a bottom scaffold board. The upper and lower fixed rails are arranged vertically in correspondence. Both the upper and lower fixed rails have groove structures for slidingly engaging the upper and lower movable sliding rails, and a connecting mesh protective screen is embedded between the upper and lower movable rails. Adjacent bottom scaffold boards are connected by an outer frame.

[0008] Preferably, it also includes a supporting and fixed guide rail, which is vertically installed at the middle position of the outer side of the floor slab at the break point via a suspension beam, and the movable slide rail unit is also horizontally connected to the supporting and fixed guide rail. The lower fixed slide rail is connected to the outer side of the supporting and fixed guide rail via a supporting base, and the upper fixed slide rail is connected to the outer side of the supporting and fixed guide rail.

[0009] Preferably, the bottom inner side of the lower fixed slide rail groove structure is connected to an upward protrusion, which is engaged with a movable roller connected to one side of the lower movable slide rail.

[0010] Preferably, the lower end of the upper fixed slide rail is connected to an outwardly extending extension plate, and reinforcing bolts and reinforcing ribs are respectively added at the connection points between the extension plate and the supporting sliding guide rail and the supporting fixed guide rail.

[0011] Preferably, a temporary traction rope is also connected to the upper moving slide rail, and the temporary traction rope is wrapped around the top of the supporting fixed guide rail to restrain the movement of the mesh frame protective screen.

[0012] Preferably, an upper support corner plate is connected to the outer side of the supporting sliding guide rail, and the other side of the upper support foot plate is connected to the bottom scaffold plate.

[0013] The present invention also provides a method for using a device for passing through a climbing scaffold on a wall of a tower crane in a super high-rise building, the method comprising the following steps: Step 1: Disconnect the external climbing scaffolding at the location where the tower crane wall attachment is connected to the main building structure. Step 2: Connect the tower crane wall-mounted component and the external climbing frame passage device as described in any one of claims 1 to 6 to the outside of the floor slab in the main building structure at the disconnection location; Step 3: Before the external climbing scaffold is lifted, the mesh protective screens on the two side support sliding guides are slid and spliced ​​together and fixed on the support fixed guides by the upper and lower moving slide rails along the upper and lower fixed slide rails, for edge protection of the floor slab at the disconnection position of the external climbing scaffold. Step 4: When the external climbing scaffold climbs to the position of the tower crane wall attachment during the climbing construction process, push the mesh frame protective screen on the support fixed guide rail to move and retract to the positions of the support sliding guide rails on both sides, so that the external climbing scaffold can pass smoothly through the tower crane wall attachment. Step 5: After the external climbing scaffold passes the tower crane wall attachment, pull the mesh frame protective screens on the two side support sliding guide rails to slide and splice them towards the middle again and fix them on the support fixed guide rails to protect the edge of the floor slab at the point where the external climbing scaffold breaks off.

[0014] Preferably, in steps 3, 4 and 5, a temporary traction rope can be used to pull the mesh frame protective screen to the middle splice point of the disconnected position of the outer climbing frame, or to pull the mesh frame protective screen back to the position of the supporting sliding guide rails on both sides.

[0015] Compared with the prior art, the beneficial effects of the present invention are: This invention provides a device and method for navigating tower cranes encountering climbing scaffolding during construction of super high-rise buildings. The device involves disconnecting the external climbing scaffolding at the location where the main building structure connects to the tower crane's wall-mounted component, and connecting the device to the outside of the floor slab at the disconnection point. The device mainly includes supporting sliding guide rails and supporting fixed guide rails. Multiple supporting sliding guide rails are vertically installed at the left and right ends of the outside of the floor slab at the disconnection point via suspension beams. Supporting fixed guide rails are vertically installed at the middle position of the outside of the floor slab at the disconnection point via suspension beams. Multiple movable slide rail units are horizontally connected between the supporting sliding guide rails and the supporting fixed guide rails. The upper and lower movable slide rails are slidably engaged within the movable slide rails via groove structures on the upper and lower fixed slide rails, and a mesh frame protective screen is embedded between the upper and lower movable slide rails. During use, when the external climbing scaffold reaches a position close to the tower crane's wall attachments during the climbing process, temporary traction ropes are used to pull the protective mesh frame towards the supporting sliding rails on both sides, creating an open area. This open area allows the external climbing scaffold to smoothly pass through the tower crane's wall attachments. This method ensures edge protection for each floor during the construction of super high-rise buildings, effectively improves construction efficiency and shortens the construction period, and its ease of use allows for widespread application in building construction operations.

Implementation

[0019] Embodiments of this disclosure will now be described in more detail with reference to the accompanying drawings. While some embodiments of this disclosure are shown in the drawings, it should be understood that this disclosure can be implemented in various forms and should not be construed as limited to the embodiments set forth herein. Rather, these embodiments are provided to provide a more thorough and complete understanding of this disclosure. It should be understood that the accompanying drawings and embodiments of this disclosure are for illustrative purposes only and are not intended to limit the scope of protection of this disclosure.

[0020] It should also be noted that, for ease of description, only the parts relevant to the invention are shown in the accompanying drawings. Unless otherwise specified, the embodiments and features described in this disclosure can be combined with each other.

[0021] This invention discloses a device and method for tower cranes used in the construction of super high-rise buildings to pass through climbing scaffolding attached to walls. The following will describe this disclosure in detail with reference to the accompanying drawings and embodiments. Example

[0022] This embodiment provides a device for passing a tower crane attached to a wall-mounted climbing scaffold in a high-rise building, including but not limited to the main building structure 1, a supporting sliding guide rail 6, and a supporting fixed guide rail 7. Typically, a tower crane wall-mounted component 4 connects the tower crane 3 to the main building structure 1. This component 4 is added during high-rise building construction to prevent lateral shear damage. Here, we need to disconnect the external climbing scaffold at the location where the tower crane wall-mounted component 4 connects to the main building structure 1, and connect the supporting sliding guide rail 6 and the supporting fixed guide rail 7 to the outside of the floor slab 2 of the main building structure 1 at the disconnection point.

[0023] Multiple supporting sliding guide rails 6 are provided, which are vertically installed at the left and right ends of the outer side of the floor slab 2 at the disconnection point via suspension beams 5. Multiple movable sliding rail units 8 and bottom scaffold boards 9 are connected above the supporting sliding guide rails 6. The movable sliding unit 8 includes an upper fixed slide rail 801 and a lower fixed slide rail 802. The upper fixed slide rail 801 is horizontally connected between the multiple supporting sliding guide rails 6, while the lower fixed slide rail 802 is horizontally connected between the multiple supporting sliding guide rails 6 via the bottom scaffold boards 9. The upper fixed slide rail 801 and the lower fixed slide rail 802 are arranged vertically opposite each other. The upper fixed slide rail 801 has a U-shaped groove structure at its upper end, and the lower fixed slide rail 802 is designed as a U-shaped groove structure. The upper movable slide rail 804 and the lower movable slide rail 805 are slidably engaged through the groove structures of the upper fixed slide rail 801 and the lower fixed slide rail 802, respectively. A connecting mesh frame protective screen 806 is embedded between the upper movable slide rail 804 and the lower movable slide rail 805. In particular, the lower moving slide rail 805 is connected to the moving roller 803 and the protrusion at the bottom of the inner side of the lower fixed slide rail 802, so that the mesh frame protective screen 806 can move back and forth along the groove structure of the upper fixed slide rail 801 and the lower fixed slide rail 802 under the drive of the lower fixed slide rail 802, making its movement smoother.

[0024] Adjacent scaffold planks 9 are connected by outer frames 12, providing lateral protection for the main building structure 1 at the disconnection point. This not only prevents wind and sand but also improves the safety of workers operating at heights. Furthermore, an upper support corner plate 10 is connected to the sliding guide rail 6, located between the moving guide rail unit 8 and the scaffold plank 9. The upper support corner plate 10 has a triangular structure, which enhances the stability and safety of the outer frames 12 after installation.

[0025] Two supporting fixed guide rails 7 are provided, which are vertically installed at the middle position on the outer side of the floor slab 2 at the disconnection point via suspension beams 5. Multiple movable slide rail units 8 are also connected to these, and are on the same horizontal line as the movable slide rail units 8 on the supporting sliding guide rail 6. Among the movable slide rail units 8 on the supporting fixed guide rail 7, the lower fixed slide rail 802 is connected to the outer side of the supporting fixed guide rail 7 via a supporting base 11, while the upper fixed slide rail 801 is directly connected to the outer side of the supporting fixed guide rail 7. When the external climbing scaffold rises to the position of the tower crane wall-mounted component 4, simply pushing the mesh frame protective screen 806 will allow the upper movable slide rail 804 and the lower movable slide rail 805 to slide open to both sides along the groove structure of the upper fixed slide rail 801 and the lower fixed slide rail 802, forming a protective area. This protective area allows the tower crane wall-mounted component 4 to pass smoothly without being affected.

[0026] To enhance the stability of the connection between the upper fixed slide rail 801 and the supporting sliding guide rail 6, an outwardly extending plate is attached to the lower end of the upper fixed slide rail 801 and fitted to the supporting sliding guide rail 6, with reinforcing bolts 808 used for fixation. Simultaneously, a reinforcing rib 807 is added between the outwardly extending plate and the upper fixed slide rail 801. The reinforcing rib 807 has a triangular structure, utilizing the stability and safety inherent in triangular structures. Therefore, the reinforcing rib 807 and reinforcing bolts 808 further strengthen the connection between the upper fixed slide rail 801 and the supporting sliding guide rail 6, thereby improving the connection stability of the mesh frame protective screen 806, making it less prone to falling off during use, and effectively enhancing overall safety.

[0027] Furthermore, a temporary traction rope 13 is connected to the upper moving slide rail 804, which loops around the upper end of the supporting fixed guide rail 7. The temporary traction rope 13 bears the working load of the lifting equipment such as the boom and hook, as well as the weight of the lifting rope, pulley block, and wire rope. This ensures the stability and safety of the crane, enabling it to perform its lifting function. Here, the temporary traction rope 13 can help the mesh frame protective screen 806 smoothly reach the intermediate splicing point, facilitating its sliding into place.

[0028] This embodiment also provides a method for using a device for passing through climbing scaffolding on a wall-mounted tower crane in a super high-rise building. The method includes the following steps: Step 1: Disconnect the external climbing scaffolding at the location where the tower crane wall attachment is connected to the main building structure. Step 2: Connect the tower crane wall-mounted component and the external climbing frame passage device as described in any one of claims 1 to 6 to the outside of the floor slab in the main building structure at the disconnection location; Step 3: Before the external climbing scaffold is lifted, the mesh protective screens on the two side support sliding guides are slid and spliced ​​together and fixed on the support fixed guides by the upper and lower moving slide rails and the upper and lower fixed slide rails, respectively, for edge protection of the floor slab at the disconnection position of the external climbing scaffold. Step 4: When the external climbing scaffold climbs to the position of the tower crane wall attachment during the climbing construction process, push the mesh frame protective screen on the support fixed guide rail to move and retract to the positions of the support sliding guide rails on both sides, so that the external climbing scaffold can pass smoothly through the tower crane wall attachment. Step 5: After the external climbing scaffold passes the tower crane wall attachment, pull the mesh frame protective screens on the two side support sliding guide rails to slide and splice them towards the middle again and fix them on the support fixed guide rails to protect the edge of the floor slab at the point where the external climbing scaffold breaks off.

[0029] Specifically, the external climbing scaffolding on the side corresponding to the location of the tower crane wall-mounted component 4 in the main building structure 1 is disconnected. At the disconnected location, a passage device for the tower crane wall-mounted component and the external climbing scaffolding in the above embodiment is connected to the outside of the floor slab 2 in the main building structure 1. This includes a vertically connected supporting sliding guide rail 6 and supporting fixed guide rail 7 between multiple floor slabs 2, and multiple horizontally connected movable slide rail units 8 across the supporting sliding guide rail 6 and supporting fixed guide rail 7. The movable slide rail units 8 are slidably connected to the upper movable slide rail 804 and the lower movable slide rail 805 via groove structures on the upper fixed slide rail 801 and the lower fixed slide rail 802, and the mesh frame protective screen 806 is embedded between the upper movable slide rail 804 and the lower movable slide rail 805. In particular, a temporary traction rope 13 can be used to pull the mesh frame protective screen 806 to the middle splicing point, or to pull the mesh frame protective screen 806 back to the supporting sliding guide rails 6 on both sides.

[0030] Before the external climbing scaffold begins its ascent, the mesh frame protective screen 806 of the movable slide rail unit 8 is initially horizontally connected to the supporting sliding guide rail 6 and the supporting fixed guide rail 7. The mesh frame protective screens 806 on both sides slide and assemble towards the center via the upper movable slide rail 804 and the lower movable slide rail 805 along the upper fixed slide rail 801 and the lower fixed slide rail 802, and are connected at the supporting fixed guide rail 7, serving as edge protection for the floor slab 2 at the location where the external climbing scaffold disconnects. During the ascent, when the external climbing scaffold reaches a position close to the tower crane wall attachment 4, the mesh frame protective screens 806 are pulled towards the supporting sliding guide rails 6 on both sides using temporary traction ropes 13, forming an open area. This open area allows the external climbing scaffold to smoothly pass through the tower crane wall attachment 4. Finally, after the external climbing scaffold passes the tower crane wall attachment 4, the mesh frame protective screens 806 on the two side support sliding guide rails 6 are pulled to slide and splice towards the middle again and are fixed on the support fixing guide rail 7, so as to protect the edge of the floor slab 2 at the location where the external climbing scaffold is disconnected.

[0031] This invention was applied to the construction of a high-rise building project comprising two 62-story super high-rise research and office buildings. The main structure is a core tube-steel frame structure with a total height of 268.35 meters. During construction, the tower crane is connected to the main structure using long main wall attachments and short secondary wall attachments. The long main wall attachments are located on the inner side of the steel structure connecting the tower crane and the main building structure, while the short secondary wall attachments are located on the outer side of the steel columns connecting the tower crane and the main building structure. However, when the external climbing scaffold on the outer side of the main structure is raised or lowered, it often encounters obstruction from the long main wall attachments and short secondary wall attachments, significantly impacting the construction progress. Therefore, this invention effectively solves the problem of the external climbing scaffold being affected by the tower crane's wall attachments during installation and climbing. In this design, the upper fixed slide rail 801 and lower fixed slide rail 802 in the movable slide rail unit 8 are made of C-shaped steel with dimensions of 180*130*3, while the upper movable slide rail 804 and lower movable slide rail 805 are made of rectangular tubes with dimensions of 100*100*3. The mesh frame protective screen 806 is set with 9 steps according to the number of walkway steps of the external climbing scaffold. Its frame is made of rectangular tubes with dimensions of 40*20*2, and the height of the mesh frame protective screen 806 is 1.3 meters. The length of the single-sided mesh frame protective screen 806 is designed to be 9 meters, with an extendable length of 5.5 meters. The length of the mesh frame protective screen 806 fixed inside the movable slide rail unit 8 is 3.5 meters. This design resolves the conflict between the long main wall attachments and short secondary wall attachments and the installation and climbing of the external climbing scaffold, while ensuring edge protection for each floor during construction, thereby improving construction efficiency and saving project time.
