Description

TECHNICAL FIELD

[0001] The present application relates to the field of building construction, in particular to a high-rise building demolition equipment and a high-rise building demolition method. BACKGROUND

[0002] Currently, the traditional high-rise building demolition generally has two types of construction methods, namely blasting demolition and mechanical demolition. The blasting demolition has high construction efficiency, but requires sufficient space around the building to be demolished to meet the safety of the area where the debris is accumulated and scattered after blasting. In addition, the huge noise, dust and vibration impact of blasting also have a greater impact on the surrounding area, so the application scenarios of blasting demolition are limited. The mechanical demolition usually uses a large hydraulic excavator, cooperates with accessories such as hydraulic breaking head, breaking tongs, and breaking shears, reaches the top of the building, and works from top to bottom to break the reinforced concrete structure. Another way of mechanical demolition is to use a specially designed super-long arm excavator to stand on the ground and gradually break and demolish the building from the side. The mechanical demolition has certain requirements on the building height and bearing capacity, and has low efficiency, long construction period, and continuous noise, vibration, and dust during construction, which disturbs the public, causes chaos at the construction site, and frequent safety accidents.

[0044] Therefore, the following detailed description of the embodiments of this application provided in the accompanying drawings is not intended to limit the scope of the claimed application, but merely to illustrate selected embodiments of the application. All other embodiments obtained by those skilled in the art based on the embodiments of this application without inventive effort are within the scope of protection of this application.

[0045] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0046] In the description of this application, it should be noted that the terms "upper" and "lower" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, or the orientation or positional relationship in which the product of the invention is usually placed when in use. They are only used to facilitate the description of this application and to simplify 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.

[0050] Example:

[0051] Please refer to Figure 1 (Refer to)Figures 2 to 17 This application provides a high-rise building demolition equipment, including at least two sets of support mechanisms 1, at least one hoisting mechanism 2, a transport mechanism 3, a frame platform 4, four sets of operating hangers 5, and at least one layer of soundproof enclosure 6; wherein, the two sets of support mechanisms 1 are respectively and vertically installed on opposite sides of the building structure 7 to be demolished, for driving the hoisting mechanism 2 to rise and fall, so that the hoisting mechanism 2 can demolish the building structure 7 at different heights; at the same time, the hoisting mechanism 2 is horizontally movable between the two sets of support mechanisms 1, for demolishing the building structure 7 at different locations; and the four sets of operating hangers 5 are respectively and detachably installed on the outer walls of opposite sides of the building structure 7; in addition, the frame platform 4 is installed on the top of the support mechanisms 1 and the operating hangers 5; the transport mechanism 3 is installed on the building structure 7 for transporting the demolished building structure 7; the soundproof enclosure 6 is openably and closably installed on the outside of the operating hangers 5 and on the top of the frame platform 4.

[0052] Furthermore, the support mechanism 1 includes at least one support column 8, a screw jack 9, an upper support beam 10, a lower support beam 11, and an electric pusher cylinder 13; wherein, the support column 8 is vertically and flexibly installed on the building structure 7, and can drive the lower support beam 11 downward through the opening 25 on the building structure 7; at the same time, the lower support beam 11 is hinged to the two opposite inner walls at the lower part of the support column 8, for fixing the support column 8 to the building structure 7 or passing through the building structure via the support column 8. The support column 7 has an opening 25; and the electric push cylinder 13 is fixedly installed on the support column 8 to drive the lower support beam 11 to open or close, so that the lower support beam 11 is fixed to the building structure 7 or passes through the opening 25 in the building structure 7; in addition, the top and bottom ends of the screw jack 9 are respectively fixedly installed on the inner wall of the support column 8 to drive the upper support beam 10 to rise and fall on the screw jack 9; the upper support beam 10 is installed on the slider of the screw jack 9, and it can move up and down relative to the support column 8. The planar arrangement of the support column 8 is determined according to the beam and column arrangement of the building structure 7 and the rigidity of the frame platform 4. The support column 8 has a lifting function, and the distance between the fulcrum of the upper support beam 10 supporting the building structure 7 and the top of the support column 8 can vary within a range exceeding one building height. Adjacent support columns 8 can be connected by pipelines. The support columns 8 can pass through openings 25 at the corners of the building floor slab. A horizontal limiting structure is installed at the openings in the building floor slab to constrain the horizontal movement of the support columns 8 during descent. Specifically, the horizontal limiting structure includes two horizontally arranged limiting plates and four track wheels 12. The two limiting plates are installed at intervals on the openings 25 near the two corners. Two vertically arranged track wheels 12 are installed at intervals on each limiting plate. The opposite sides of the support columns 8 are movably connected to the four track wheels 12, thereby achieving the effect of constraining the horizontal movement of the support columns 8 during descent.

[0053] It should be noted that, depending on the actual dimensions of the building plan, the hoisting mechanism 2 can be arranged in various ways. The arrangement mainly depends on the width of the building: if the building width is less than 24m, a single-span arrangement is preferred, that is, two rows of supporting columns 8 are set on the plane, and a track beam 15 is set on the top of the supporting columns 8 to install a single-span overhead crane 17. The number of overhead cranes 17 depends on the requirements. If the building length is greater than 40m, it is recommended to arrange 2 or more cranes. When the building width is greater than 24m, which exceeds the economic span of conventional Bailey beams and overhead cranes 17, a double-span arrangement can be considered, that is, three rows of supporting columns 8 are arranged on the plane, one track beam 15 is set on the top of the outer supporting columns 8, and two track beams 15 are set on the top of the middle row of supporting columns 8 to install two spans of overhead cranes 17. In addition, a top support plate is installed on the top of each support column 8, and the track beam 15 of the overhead crane 17 is installed on the top support plate. A short column extends out from one corner of the top support plate, and the top of the short column supports the frame platform 4.

[0054] The height of the supporting column 8 must ensure that the clear distance between the bottom of the frame platform 4 and the top floor is not less than 9m, in order to meet the operational requirements of structural demolition. The bottom end of the supporting column 8 must penetrate the lower floor by at least 1m.

[0055] It should be noted that the upper support beam 10 and the lower support beam 11 can be alternately stressed, allowing the support column 8 to drive the entire high-rise building demolition equipment to descend. The specific working principle is as follows: After the building structure 7 on the top floor slab is demolished, the upper support beam 10 is in the air. At this time, the support column 8 relies on the lower support beam 11 located on the middle layer 23 to transmit force and bear all the load. Then, the screw jack is activated, rotating clockwise, which drives the upper support beam 10 to move downwards relative to the screw jack until it contacts the upper layer 22, allowing the upper support beam 10 to bear all the load on the support mechanism 1. This allows the upper support beam 10 to replace the lower support beam 11 and become the new path for load transfer to the building structure 7. Then… Start the electric push cylinder 13, which drives the lower support beam 11 to flip and close, shortening its projected length to be able to pass through the opening 25 on the middle layer 23. Start the screw jack and reverse it. At this time, fix the upper support beam 10 on the upper layer 22 and keep it stationary, so that the support column 8, the screw jack, and the upper structure connected to the support column 8 (frame platform 4, operating bracket 5, and soundproof cover 6, etc.) move downward together, and drive the closed lower support beam 11 to open after passing through the opening 25 on the middle layer 23, until the lower support beam 11 is engaged in the opening 25 on the lower layer 24, so that the lower support beam 11 bears all the load on the support mechanism 1, thereby replacing the upper support beam 10 to transfer the load.

[0056] Therefore, the device, through the synchronously lifting support mechanism 1, allows the entire high-rise building demolition equipment to be conveniently lowered as a whole. After being lowered into place, no much adjustment or preparation work is required before proceeding with the demolition work on the next floor. Furthermore, the support mechanism 1 only requires opening holes in the building floor slab so that the support columns 8 can pass through smoothly. It is supported by the lower support beam at the corner where the longitudinal and transverse beams intersect at the beam-column node. The main support point is located on the middle floor 23, which will not affect the demolition work of the structure above the upper floor 22. The operation of the entire support mechanism 1 is relatively simple.

[0057] Specifically, the supporting column 8 includes two profiles and multiple connecting plates. The two profiles are arranged in parallel and spaced apart, and connected by multiple connecting plates spaced apart along the height direction. The axis of symmetry between the two profiles is set at a 45° angle to the column grid axis on the building structure 7, so that the supporting beam 11 below can be supported on the longitudinal and transverse beams at the corner. In this embodiment, the profiles can be I-beams, channel steel, and H-beams, etc.

[0058] Furthermore, the lower support beam 11 includes a wedge block 14, a first support portion 26, and a second support portion 27; the first support portion 26 and the second support portion 27 are respectively hinged at intervals between the gaps of the two profiles, and can be rotated in the direction of mutual contraction and closing or mutual extension and opening; the wedge block 14 can move into or out of the gap between the first support portion 26 and the second support portion 27, and is used to engage with the gap between the first support portion 26 and the second support portion 27 so that the lower support beam 11 is engaged with the opening 25 or moved out of the first support portion 26. The lower support beam 11 passes through the opening 25 between the first support part 26 and the second support part 27; the drive end of the electric push cylinder 13 is connected to the wedge block 14 for driving the wedge block 14 to rise and fall relative to the support column 8, so that the wedge block 14 moves into or out of the gap between the first support part 26 and the second support part 27, and causes the first support part 26 and the second support part 27 to flip in the direction of mutual contraction and closing or mutual extension and opening, so that the two lower support beams 11 can pass through the opening 25 or be engaged with the opening 25.

[0059] When the electric actuator 13 pulls the wedge block 14 to a height range away from the lower support beam 11, the first support portion 26 and the second support portion 27 of the lower support beam 11 can freely flip upwards. When the support column 8 moves downwards, the first support portion 26 and the second support portion 27 of the lower support beam 11 are pushed upwards by the opening 25 and automatically flip upwards after passing through the opening 25. Under their own weight, the first support portion 26 and the second support portion 27 of the lower support beam 11 automatically flip to a horizontal state. When the electric actuator 13 pushes the wedge block 14 to its uppermost position, the wedge block 14 constrains the first support portion 26 and the second support portion 27 of the lower support beam 11 to flip upwards, thereby enabling the lower support beam 11 to support the building floor slab and bear the load.

[0060] In addition, the hoisting mechanism 2 includes a track beam 15, steel rails 16, and a gantry crane 17. Each set of support mechanisms 1 has a top support plate on its top. The track beam 15 is installed between two top support plates, and the steel rails 16 are installed on the track beam 15. The gantry crane 17 is laterally movable and installed on the steel rails 16. The gantry crane 17 can move along the steel rails 16, essentially covering the entire building plan. Blind spots at both ends and sides that are difficult for the gantry crane 17 to cover can be avoided by adjusting the floor slab segmentation scheme.

[0061] Furthermore, the transportation mechanism 3 includes a first construction elevator 18 and a second construction elevator 19. The first construction elevator 18 is attached to the lower part of the outer wall of the building structure 7. The second construction elevator 19 is vertically installed in the elevator shaft inside the building structure 7. The second construction elevator 19 includes a cage 20 with an open top. One side of the cage 20 is equipped with an openable frame door, and the bottom inner wall is equipped with a detachable tray 21. The second construction elevator 19 adopts a cage 20 design with an open top. The object to be hoisted can be directly hoisted into the cage 20 after being moved horizontally by the overhead crane 17, and then transported downwards to the ground. The second construction elevator 19 adopts a beamless design. Its hanging steel wire ropes are wrapped around both sides of the cage 20 from below. One end is anchored to the side wall of the shaft, and the other end turns downwards after turning at the top of the side wall on the other side of the shaft and enters its drive structure. In addition, the second construction elevator 19 can also use electromagnetic resistance to control the descent speed of the cage 20, converting the gravitational potential energy of the building components during the descent into electrical energy.

[0062] After being cut, the building components are first transported horizontally by the overhead crane 17. Horizontal components such as walls and columns can be directly hoisted into the hoisting cage 20. Horizontal components such as floor slabs and beams are turned over before being hoisted into the hoisting cage 20 of the second construction elevator 19. The components are placed diagonally inside the hoisting cage 20 to make full use of its size. After the components are placed into the hoisting cage 20, they are temporarily reinforced with diagonal braces at the bottom of the cage 20. After the components are transported to the ground using the second construction elevator 19, they can be dragged out of the building by horizontal towing and then loaded onto trucks for transport.

[0063] Therefore, this device integrates a horizontal transport system (gantry crane 17), a vertical transport system (second construction elevator 19), and an external first construction elevator 18, eliminating the need for external tower cranes and enabling 24 / 7 operation, thus avoiding the limitations of tower crane hoisting. Separating horizontal and vertical transport avoids prolonged equipment occupation and time consumption, improving overall construction efficiency. The second construction elevator 19 features a top-opening design, facilitating the direct hoisting of components into its cage 20 by the gantry crane 17. Using the second construction elevator 19 also significantly increases vertical transport speed, thereby improving overall transport efficiency.

[0064] It should be noted that the frame platform 4 is a frame structure composed of multiple longitudinally and transversely arranged 321 Bailey beams connected by multiple connecting nodes. The lower part of the connecting nodes is connected to the top of the supporting column 8; the bottom of the outer Bailey beams is connected to the longitudinally and transverse steel sections through the first connecting seat, and the longitudinally and transverse steel sections are connected to the top of the suspension rod of the operating bracket 5 through the second connecting seat. The frame platform 4 is composed of 321 Bailey beams and connecting nodes, which improves the adaptability of the frame platform 4, reduces the manufacturing cost of the platform, and provides sufficient rigidity and strength to provide enough hanging points, facilitating equipment integration and construction auxiliary hanging. At the same time, the operating bracket 5 includes multiple operating platforms connected sequentially from bottom to top. The operating platforms are arranged within the range between the outer walls of the middle layer 23 and the lower layer 24, and each operating platform has a hinged flip platform on the side closest to the building structure 7. The width of the flip platform is slightly larger than the gap between the building structure 7 and the operating bracket 5. Furthermore, the soundproof enclosure 6 can be made of multi-layer sound insulation and sound absorption materials. Furthermore, various integrated devices are attached to the frame platform 4 or the supporting columns 8. These can include existing technologies such as dust suppression spraying equipment, laser projection layout equipment, and retractable roofs. The specific arrangement is the same as in existing structures and will not be elaborated here. A dust suppression spraying system is integrated under the frame platform 4, improving the internal working environment. In addition, the device also integrates laser projection layout equipment, simplifying the layout work of cutting seams and improving efficiency. Moreover, the cutting of the building structure 7 can be achieved using wire saw cutting machines, coil saw cutting machines, etc. There is no need to erect scaffolds below before cutting horizontal components such as floor slabs and beams. For floor slabs, steel spreader beams can be used for temporary support. For beams, oblique cuts can be made on both sides to ensure that the final beam side elevation is an inverted trapezoidal shape that is wider at the top and narrower at the bottom, thereby ensuring that the beam will not fall.

[0065] Specifically, the soundproof enclosure 6 covers the three working floors at the top in terms of height, and it covers the perimeter of the operating rack 5 and the frame platform 4, providing safety conditions for external operations.

[0066] Furthermore, this embodiment also provides a method for demolishing high-rise buildings, which mainly uses the above-mentioned high-rise building demolition equipment for demolition; the method includes the following steps:

[0067] Step 1: Install the first construction elevator 18 on the outside of the building structure 7. Use the first construction elevator 18 to transport the small roof hoist to the roof of the building for installation. At the same time, dismantle part of the structure on the top of the building to create conditions for the installation of the high-rise building demolition equipment.

[0068] Step 2: Use the roof crane to install high-rise building demolition equipment on the top of the building, and transport all kinds of equipment and tools required for the operation to the top of the building, and then dismantle the roof crane;

[0069] Step 3: Simultaneously carry out structural demolition, secondary structure demolition, decoration and mechanical / electrical system demolition on the three interconnected upper, middle and lower floors at the top of the building using a parallel, sequential operation method.

[0070] The superstructure on building structure 7 is demolished as follows: First, the cutting seam is marked on the upper floor 22 using laser projection equipment. Then, the upper floor 22 is cut into sections using cutting machinery. During this process, the upper floor 22 is supported and suspended. The cut floor slabs are then hoisted to the second construction elevator 19 using a crane 17 and transported to the ground floor using the second construction elevator 19. After that, they are horizontally moved outside the building and transported away. After the floor slabs are cut and demolished, the beams, walls, and columns are cut and hoisted.

[0071] Secondary structure demolition of the mid-rise building on building structure 7: First, use a crusher to break the secondary structure, namely the masonry infill wall, then use a loader to collect the debris and load it into a transport truck, and then use the transport truck to transport it to the construction elevator and down to the ground.

[0072] The mechanical and electrical equipment and interior decoration materials of the lower building on the building structure 7 are removed: First, the exterior decoration materials such as windows and curtain walls are removed using the operating platform. Inside the building, the decoration materials are removed manually. Then, the removed decoration materials are transported horizontally to the second construction elevator 19 using a forklift and transported downwards to the ground.

[0073] Step four: After the demolition work on the upper, middle and lower floors is completed simultaneously, an opening 25 is made in the floor slab of the next floor, and a horizontal limiting structure is installed around the opening 25 to create conditions for the downward movement of the supporting column 8. The second construction elevator 19 is used to move the various working equipment on each working floor to the corresponding next working floor in sequence, and the flip platform on the operating bracket 5 is retracted. The supporting mechanism 1 is lowered synchronously so that the entire high-rise building demolition equipment is lowered one floor to the next working floor. The construction operation in step three is repeated to achieve the demolition of the structure, secondary mechanism, electromechanical equipment and interior decoration materials of the next floor.

[0074] Step 5: When the building structure 7 is demolished down to the remaining four floors, the entire high-rise building demolition equipment is dismantled using a truck crane, and the remaining part of the building is demolished using conventional demolition methods.

[0075] In summary, the high-rise building demolition equipment and method described in this application achieve factory-like demolition operations, improving efficiency, ensuring construction safety, and reducing noise. Furthermore, the operation is unaffected by external weather, increasing available working time. Simultaneously, it improves the working environment, increases worker efficiency, and avoids dust and noise pollution by creating a closed environment. Moreover, throughout the entire demolition process, only a soundproof enclosure 6 covers the top of the building, with no construction machinery such as tower cranes exposed, resulting in minimal noise pollution and environmental safety during the demolition process.

[0076] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
