Description

Technical Field

[0001] This invention relates to the field of high-rise building structure demolition, and in particular to a green demolition method and demolition machine platform for high-rise buildings. Background Technology

[0002] Demolition machines are mechanical devices used to dismantle buildings. Traditional demolition machines are excavators modified with extended arms for area demolition operations, which presents problems such as dust and falling objects, significantly impacting the surrounding environment and personnel safety. Furthermore, extended-arm excavators are limited by their size and are difficult to use for demolishing high-rise buildings.

[0003] Existing high-rise demolition machines operate from the top floor downwards, but their operation still relies on traditional crushing concepts. They are poorly adaptable to the use of complex structures and components, posing potential safety hazards. Furthermore, the properties of the solid waste from demolition vary greatly, limiting their application scope. Summary of the Invention

[0004] The purpose of this invention is to overcome the defects of the prior art by providing a green demolition method and demolition machine platform for high-rise buildings, in order to solve the safety problems of demolishing complex buildings.

[0005] The objective of this invention can be achieved through the following technical solutions:

[0006] As a first aspect of the present invention, a method for demolishing a high-rise building is provided, comprising the following steps:

[0007] Based on infrared scanning devices, basic data of the demolition layer structure are identified to obtain information on deformation and mechanical property damage.

[0008] By using infrared recognition detection results, the resource utilization potential of each part of the structure can be determined, each component can be classified and graded, and reuse strategies can be planned at the substructure, component, and material levels respectively.

[0009] Establish a real-time dismantling model of high-rise structures to provide parameter basis for mechanical analysis of the entire dismantling process;

[0010] Demolition machines were used for cutting, dismantling, and dismantling.

[0011] Disassembly, hoisting, and mechanical crushing;

[0012] Repeat the above steps until the entire structure is removed from top to bottom.

[0013] Furthermore, the criteria for determining the dismantling targets include building tilt, ground deformation, actual component dimensions, deflection and cracks, node type and connection status, material strength and durability corrosion status.

[0014] Furthermore, the real-time dismantling model designs the dismantling process based on the force transmission mechanism of structural components and their collaborative force-bearing mechanism with temporary supports; first, the floor slabs are dismantled, and then the secondary beams, main beams, exterior walls, columns, shear walls and stairs are dismantled in sequence.

[0015] Furthermore, the disassembly model optimizes the decision-making process for the component disassembly sequence, specifically as follows:

[0016] Q = [q1 q2 q3……q n ]

[0017] K(Q)u=F(Q)

[0018] The constraints are:

[0019] P[R≥S(u)]≥Φ(β T )

[0020] In the formula, Q represents the component dismantling sequence; q represents the specific component; K(Q) is the structural stiffness matrix under infrared identification during dismantling in a dangerous state; u represents the nodal displacement response under the structural state analyzed by infrared monitoring; F(Q) represents the nodal load under the designed dismantling sequence; S represents the controlling load effect; R represents the corresponding resistance; Φ(·) represents the standard normal distribution function; β T P[·] represents the reliability index of the target; P[·] represents the probability of the event within the parentheses, which is minimized.

[0021] Furthermore, after the infrared scanning device positions the cut and dismantled components, it re-verifies the remaining substructure after hoisting. The area scanning speed of the probe is less than the set speed threshold, and the defect identification range reaches the set accuracy.

[0022] Based on the strength of the scan signal reflection, detection points with internal defects exceeding a set threshold and detection points with component deformation exceeding a set threshold are identified as key areas of concern.

[0023] As a second aspect of the present invention, a demolition machine platform is provided for applying the high-rise building demolition method described above, the demolition machine platform comprising:

[0024] The work platform is located to the side of the area to be demolished;

[0025] An infrared detection device is installed on the side of the work platform facing the area to be demolished, and is used to dynamically scan the area to be demolished, identify and adjust the demolition path.

[0026] The lifting device is connected to the working platform and fixed to the connecting rods, and is used to realize the longitudinal movement of the demolition machine platform;

[0027] Demolition equipment, connected to a work platform, includes a boom and demolition tools;

[0028] A fixed module assembly, connected to a lifting device, is used to secure the lower layer during the upper layer removal process.

[0029] Furthermore, the demolition device includes: a steering base fixed to the working platform; a boom mounted on the steering base, the boom including two cooperating movable rods and positioning rods; a demolition tool connected to the other end of the boom; the demolition tool including a cutting tool and a crushing tool, the cutting tool being a replaceable 360° multi-hinged movable cutting saw; the crushing tool being a replaceable hydraulic breaker or hydraulic clamp.

[0030] Furthermore, the lifting device includes: a hydraulic telescopic rod, a leveling platform, and a lateral stabilization module; one end of the hydraulic telescopic rod is anchored to the demolition machine platform; the side of the hydraulic telescopic rod near the wall is anchored to a connecting rod; the other end of the hydraulic telescopic rod is connected to the leveling platform; and a lateral stabilization module is provided on the other side of the leveling platform.

[0031] Furthermore, the fixing module group is connected to the lateral stabilization module to achieve lower-level fixation during the upper-level removal process, including:

[0032] The sliding formwork machine track moving rod and the sliding formwork machine unit fixing platform are set on the side of the lateral stabilization module facing the unremoved area; one side of the sliding formwork machine unit fixing platform is provided with the sliding formwork machine track moving rod connected to the electric drive unit of the sliding formwork machine, and the other side is provided with a movable right-angle rod;

[0033] The electric drive unit of the slipform machine is used to realize the relative descent between the slipform machine track moving rod and the fixed platform of the slipform machine unit.

[0034] Furthermore, after assembly, the demolition machine platform is raised to the demolition area height via hydraulic rods, and the hydraulic telescopic rods and the work platform are connected and fixed through the connecting rods; the movable right-angle rods rely on the balcony structure of the undemolished area and are equipped with detachable reinforcement plates to execute demolition commands.

[0035] Compared with the prior art, the present invention has the following beneficial effects:

[0036] 1) This invention designs a green demolition method for high-rise buildings. Based on the lateral infrared probe, it identifies the overall deformation and mechanical performance degradation of the high-rise structure, judges the resource utilization potential of each part of the structure, classifies and grades each component for reuse strategy planning, and realizes efficient green demolition of high-rise buildings from top to bottom with the help of demolition equipment.

[0037] 2) The cutting tool 5 involved in this invention is a 360° multi-hinge movable cutting saw that can be replaced. With the help of the movable rod and positioning rod of the guide arm, the crushing head and the cutting head are precisely positioned, and various components can be spatially cut and decomposed.

[0038] 3) The present invention establishes a control center 4 on the demolition machine platform 3, combined with a real-time condition model of the high-rise structure, to provide real-time parameter basis for mechanical analysis of the entire demolition process. It can detect internal defects during the cutting process and identify the nature of substructure defects, which facilitates ensuring the safety of component-level demolition.

[0046] The present invention will now be described in detail with reference to the accompanying drawings and specific embodiments. These embodiments are based on the technical solution of the present invention and provide detailed implementation methods and specific operating procedures. However, the scope of protection of the present invention is not limited to the following embodiments.

[0047] Example 1

[0048] First, an embodiment of the method of the present invention is given.

[0049] like Figure 1 As shown, this embodiment provides a green demolition method for high-rise buildings, including the following steps:

[0050] S1. Use infrared probes to obtain basic data on the building structure and components of the demolition layer, including the overall deformation and mechanical property degradation.

[0051] S2. Based on the identification and detection results, determine the resource utilization potential of each part of the structure, classify and grade each component, and plan the reuse strategies at the substructure, component, and material levels respectively.

[0052] The criteria for determining the target to be dismantled include building tilt, ground deformation, actual dimensions of components, deflection and cracks, joint type and connection status, material strength and durability corrosion status.

[0053] Supplement the materials of various structural components, and classify and dismantle non-load-bearing components according to decorative parts, ceilings, fire protection pipe networks, recyclable steel materials, and brick walls.

[0054] S3. Establish a real-time dismantling model of high-rise structures to provide parameter basis for mechanical analysis of the entire dismantling process.

[0055] The real-time dismantling model designs the dismantling process based on the force transmission mechanism of structural components and their collaborative force-bearing mechanism with temporary supports; first, the floor slabs are dismantled, and then the secondary beams, main beams, exterior walls, columns, shear walls, and stairs are dismantled in sequence.

[0056] The disassembly model optimizes the decision-making process for the component removal sequence, specifically as follows:

[0057] Q = [q1 q2 q3……q n ]

[0058] K(Q)u=F(Q)

[0059] The constraints are:

[0060] P[R≥S(u)]≥Φ(β T )

[0061] Q represents the component dismantling sequence; q represents the specific component; K(Q) represents the structural stiffness matrix under infrared identification during dismantling in a hazardous state; u represents the nodal displacement response under the structural state analyzed by infrared monitoring; F(Q) represents the nodal load under the designed dismantling sequence; S represents the controlling load effect; R represents the corresponding resistance; Φ(·) represents the standard normal distribution function; β T P[·] represents the reliability index of the target; P[·] represents the probability of the event within the parentheses, which is minimized.

[0062] Based on the overall building information, a demolition decomposition model is established. For structures above the sixth floor, mechanical cutting is used for dismantling, maximizing the standardized control and classification of demolition materials, improving the integrity of old building components, and facilitating the recycling of materials and even components. For structures below the sixth floor, the progressive collapse mechanism is utilized to locally damage some structural components, causing them to lose their original load-bearing function. The remaining related structures cannot establish a new equilibrium state through other alternative force transmission paths, ultimately leading to the overall collapse of the structure.

[0063] For standard floors with 6 or more stories, the demolition sequence will be adjusted according to the principle of prioritizing the demolition of one side. Figure 2 The "step-like" cutting and hoisting demolition method involves segmenting the structure sequentially, resulting in a "step-like" shape during demolition. Components are cut and hoisted in combinations such as main beams and floor slabs, secondary beams and floor slabs, main beams and frame columns, and main beams and structural columns. The component cutting is designed to proceed with slabs first, followed by beams and columns, improving overall project efficiency. The data package for the cut components includes main beams and floor slabs, secondary beams and floor slabs, main beams and frame columns, main beams and structural columns, and allowable areas for structural defects.

[0064] For the section below the 6th floor, non-load-bearing components were also removed in advance by category. By systematically weakening the load-bearing components, the direction and mode of structural collapse were controlled.

[0065] During the cutting and dismantling process, infrared probes can dynamically scan and capture defects in the remaining substructure in real time, and determine the safety of the dismantling based on preset parameters and defect categories.

[0066] S4. Execute hoisting and crushing commands.

[0067] After completing the anchoring of the fixed module group and fixed through frame of the dismantling machine platform, the dismantling equipment performs pre-positioning actions according to the defined dismantling area and its travel trajectory. The cutting equipment of the demolition machine platform cuts the components sequentially according to the designed dismantling process; during the cutting process, infrared sensors collect data to analyze the failure risk of components in the stress area and determine the rationality of the dismantling.

[0068] The relative coordinates of the equipment in the crushing area are automatically adjusted to determine the orientation of the crushing substructure.

[0069] Infrared probes dynamically scan and capture substructure defects before breakage, determining the direction and extent of structural tilt after breakage.

[0070] The demolition layer infrared recognition model can be matched with digital terminals such as APP to become a visualized 3D building information model according to actual needs.

[0071] S5. Disassembly, hoisting, and mechanical crushing.

[0072] Use hoisting machinery to transport the cutting components, and repeat steps 1-5 to execute the crushing command to complete the overall demolition from top to bottom.

[0073] Example 2

[0074] Combination Figure 3 and Figure 4 An embodiment of the demolition machine platform of the present invention is provided. The demolition machine platform includes a working platform 3, which is located to the side of the area to be demolished 1; a lifting device 9, which is located below the working platform 3 to realize the longitudinal movement of the demolition machine; a demolition device, including a boom, a cutting tool 5 and a crushing tool 6, the boom being connected to the working platform 3, the boom including a movable rod 15 and a positioning rod 17, which work together to achieve precise positioning of the cutting tool 5 and the crushing tool 6; an infrared detection device 8, used to dynamically scan the demolition area, identify and adjust the demolition path; and a fixing module group, connected to the lifting device, to realize the fixing of the lower layer during the upper layer demolition process.

[0075] The work platform 3 is also equipped with a personnel control center 4 for real-time control commands. The infrared detection device 8 is connected to the personnel control center 4 in real time. The control center 4 is connected to the multi-directional integrated cutting tool 5 and the multi-directional integrated crushing tool 6 of the dismantling device. The "well"-shaped connecting rod 10 includes two through-type long rods and two reinforcing short rods. The rods are connected to the lifting device of the dismantling platform and the nodes between the rods are all anchored.

[0076] The infrared detection device 8 includes an operating platform 3 facing the demolition area 1, equipped with an infrared probe connected to the control center 4, providing real-time feedback on the overall structural deformation and mechanical assessment during the cutting process. The infrared detection device 8 identifies the degree of damage or cracks in the materials, components, and substructures to be dismantled and sends instructions to the control center 4 to determine the safety of the dismantling. The infrared detection device 8 can detect internal defects, achieve spatial location of component defects, and identify the nature of the structural stress state, exhibiting high sensitivity, especially to the deformation of the substructures to be demolished. Different detection processes are used for different component types, depending on the deformation, defects, cracks, and stress state of the target materials, components, and substructures; generally, it is recommended that the infrared identification device be equipped with a surface-controlled infrared probe.

[0077] After the infrared detection device has positioned the 8 pairs of components to be cut and dismantled, the remaining substructure after hoisting should be rechecked. The scanning speed of the probe should not exceed 100mm. 2 The defect identification range accuracy should ultimately reach 0.5mm per minute. Based on the strength of the scan signal reflection, detection points with internal defects exceeding 20% ​​and component deformation exceeding 5% should be identified as key areas of concern, providing a reference range for the safe implementation of cutting and dismantling.

[0078] like Figure 5As shown, the multi-directional integrated cutting tool 5 includes: a 360° movable cutting device 13, an integrated hydraulic clamp 14, a movable rod 15, a connecting bolt 16, a positioning rod 17, and a steering base 18. The movable cutting device 13 can achieve flexible angle cutting, and the hydraulic clamp 14 can achieve large-angle clamping and release. The cutting tool 5 is fixed to the working platform 3 via the steering base 18. A boom is installed on the steering base 18, and the boom has two sections, including two movable rods 15 and two positioning rods 17. One end of one movable rod 15 is fixed to the first positioning rod 17 via the connecting bolt 16, and the other end is connected to the end of the second positioning rod 17; one end of the other movable rod 15 is fixed to the second positioning rod 17 via the connecting bolt 16, and the other end is connected to the end of the cutting tool 5. The precise positioning of the cutting tool 5 is achieved through the coordinated operation of the movable rods 15 and the positioning rods 17.

[0079] The cutting tool 5 can be replaced with a 360° multi-hinged moving cutting saw; the crushing tool 6 can be replaced with a hydraulic breaker or a hydraulic clamp.

[0080] The lifting device includes anchor bolts 7, hydraulic telescopic rods 9, leveling platform 11, and lateral stabilization module 12. The lifting device is connected to the demolition machine platform 3 via anchor bolts 7; the hydraulic telescopic rod 9 is anchored to the through connecting rod 10 near the wall, and the leveling platform 11 is fixed to the bottom of the hydraulic telescopic rod 9. The lateral stabilization module 12 is installed below the leveling platform 11.

[0081] like Figure 6 As shown, the fixed module group is connected to the lateral stabilization module 12 to achieve lower-level fixation during the upper-level demolition process. It includes a slipform machine track moving rod 21 and a slipform machine unit fixing platform 22, both located on the side of the lateral stabilization module 12 facing the area to be demolished. One side of the slipform machine unit fixing platform 22 is equipped with a slipform machine track moving rod 21 connected to the slipform machine electric drive unit 23, while the other side has a movable right-angle rod 19. The movable right-angle rod 19 relies on the balcony structure of the un-demolished area 2 and is reinforced with a detachable reinforcing plate 20 to improve safety. After the demolition of area 1 is completed, the slipform machine electric drive unit 23 lowers the slipform machine track moving rod 21 relative to the slipform machine unit fixing platform 22. The dimensions of the movable right-angle rod 19 can be adjusted according to the dimensions of the demolished building structure; the slipform machine electric drive unit 23 uses a 50kW diesel engine as its power source.

[0082] When the demolition platform of this embodiment is applied to implement the demolition method of the above embodiment, the specific process of step 4 of the demolition method is as follows:

[0083] The demolition machine components are hoisted onto the segmented platform of the high-rise building and assembled. After assembly, the demolition machine platform is raised to the demolition area height by hydraulic rods 9. The lateral stabilization module 12 and the demolition machine platform 3 are connected and fixed by "well"-shaped anchor rods 10. The movable right-angle rods 19 rely on the balcony structure of the undemolished area 2 and are equipped with detachable reinforcement plates 20. The demolition machine platform is cut and disassembled according to the predefined dismantling area.

[0084] When the demolition platform of this embodiment is applied to the demolition method of the above embodiment, the specific process of step 5 of the demolition method is as follows:

[0085] After disassembling and hoisting and mechanical crushing, and completing the crushing of the area to be demolished 1, the detachable reinforcement plate 20 is removed and the engagement state of the movable right-angle rod 19 is released. The relative descent between the fixed platform 21 of the slipform machine and the crawler moving rod 22 of the slipform machine is achieved by the electric drive unit 23 of the slipform machine. After descending to the designated position of the next floor, the movable right-angle rod 19 is used again to rely on the balcony structure of the un-demolished area and the detachable reinforcement plate 20 is added. After disassembling the through frame 10 and installing anchors in the area to be demolished on the lower floor, the process of steps 1-4 is repeated.

[0086] The preferred embodiments of the present invention have been described in detail above. It should be understood that those skilled in the art can make numerous modifications and variations based on the concept of the present invention without creative effort. Therefore, all technical solutions that can be obtained by those skilled in the art based on the concept of the present invention through logical analysis, reasoning, or limited experimentation on the basis of existing technology should be within the scope of protection defined by the claims.
