Description

Technical Field

[0001] This invention relates to the field of building demolition engineering technology, and in particular to a differentiated configuration method for demolition equipment for concrete structural components. Background Technology

[0002] In current building demolition operations, the selection and combination of demolition equipment usually rely on the experience and judgment of construction workers, lacking a systematic configuration method. When faced with different types of concrete structural components (floor slabs, beams, columns), a "one-size-fits-all" uniform equipment configuration scheme is generally adopted, that is, using the same set or type of equipment to handle the demolition of all components.

[0003] This equipment configuration scheme has the following technical defects:

[0004] (1) Lack of targeted equipment configuration: The structural characteristics, stress state and demolition process of the three types of components, namely floor slabs, beams and columns, are significantly different, but the existing technology has not established equipment configuration rules or methods for each type of component;

[0005] (2) Low efficiency of configuration decision-making: Equipment configuration relies entirely on repeated trial and error adjustments by construction personnel on site. The equipment selection and combination configuration cycle is long and it is difficult to adapt to the on-site construction rhythm.

[0006] (3) Serious additional damage to components: The selected equipment's fixing method and cutting tools are not compatible with the structural characteristics of the components, and additional damage is easily caused during the dismantling and cutting process, reducing the reusability value of concrete components;

[0007] (4) Significant construction safety risks: Incompatible equipment configuration leads to unstable fixing and cutting, increasing the risk of safety accidents during demolition operations;

[0008] (5) There are blind spots in the current research and development direction: The industry's research and development direction focuses on the equipment itself, such as specific models of demolition robots and hydraulic crushing equipment, but ignores the core pre-process of "scientifically selecting complete sets of equipment according to the type of components". Even if high-performance demolition equipment is used, the technical advantages of the equipment cannot be fully utilized without the supporting differentiated configuration method.

[0009] Therefore, how to provide a systematic, standardized, and automatically matched method for the differentiated configuration of concrete structural component demolition equipment is a technical problem that urgently needs to be solved by those skilled in the art. Summary of the Invention

[0010] This invention provides a differentiated configuration method for demolition equipment of concrete structural components to solve the technical problems of blind equipment configuration, low efficiency, large damage and poor safety in existing demolition operations.

[0011] To address the aforementioned technical problems, this invention provides a differentiated configuration method for concrete structure component demolition equipment, comprising the following steps:

[0012] Step 1: Identify the type of concrete structural member to be demolished and extract the corresponding structural parameters for each type of concrete structural member;

[0013] Step 2: Pre-establish an equipment configuration library that adapts to different types and structural parameters of concrete structural components. The equipment configuration library stores differentiated complete equipment configuration schemes for different components. Each equipment configuration scheme includes combination rules for temporary fixing modules, cutting modules, and transfer modules.

[0014] Step 3: Based on the component type and structural parameters obtained in Step 1, match the appropriate complete equipment configuration scheme in the equipment configuration library. The matching rules include precise matching, fuzzy matching and custom matching.

[0015] Step 4: Set parameters for the matched complete equipment configuration scheme, and perform safety verification of temporary fixing force and working surface bearing capacity based on the self-weight of the components;

[0016] Step 5: Configure the safety interlock control logic during the demolition operation, including: cutting can only be started after temporary fixing is completed; temporary fixing of components can only be released after cutting is completed; and transportation operations can only be performed after the cutting module is moved away.

[0017] Step 6: Execute the corresponding component dismantling operation according to the matched equipment configuration scheme, collect actual on-site operation data and feed it back to the equipment configuration library to optimize the combination rules and matching rules of the complete set of equipment configuration scheme.

[0018] Preferably, in step 1, the identification of component types and the extraction of structural parameters are carried out using one or more of the following methods: automatic extraction from BIM model, input of construction drawing information, on-site laser scanning identification, or manual input.

[0019] Preferably, in step 1, the concrete structural components to be demolished are divided into three categories: floor slabs, beams, and columns. The structural parameters corresponding to the floor slabs include slab thickness, plan dimensions, concrete strength grade, and reinforcement information. The structural parameters corresponding to the beams include cross-sectional width, cross-sectional height, span, and concrete strength grade. The structural parameters corresponding to the columns include cross-sectional shape, cross-sectional dimensions, column height, and concrete strength grade.

[0020] Preferably, in step 2,

[0021] The equipment configuration schemes corresponding to the floor slabs include:

[0022] Option A: For single-story floor slabs or slabs with a thickness ≤200mm: the temporary fixing module is configured with a 4-point lifting mechanism, and the lifting head is a flat support plate; the cutting module is configured with a mobile cutting machine for single-sided cutting.

[0023] Option B: For double-layer floor slabs or slabs with a thickness greater than 200mm: the temporary fixing module is configured with a double-sided clamping mechanism; the cutting module is configured for double-sided cutting or layered cutting.

[0024] Preferably, in step 2,

[0025] The equipment configuration options corresponding to the crossbeam include:

[0026] Option A: Section height ≤ 200mm: Temporary fixing module is configured as a single-point push rod type support head, supporting from the middle of the bottom of the beam; cutting module is configured as a mobile cutting machine;

[0027] Option B: 200mm < cross-section height ≤ 450mm: temporary fixing module configured with dual-point support mode of main support and auxiliary support; cutting module configured as a mobile cutting machine;

[0028] Option C: Section height > 450mm: A segmented cutting strategy is adopted, and the temporary fixing module is configured as a single-point or double-point support mode.

[0029] Preferably, in step 2,

[0030] The equipment configuration options corresponding to the pillar include:

[0031] Option A: Square column with a cross-section ≤ 500mm × 500mm: Temporary fixing module configured as double-sided hydraulic clamping arms; cutting module configured as a mobile cutting machine;

[0032] Option B: Circular column, diameter ≤ 500mm: Temporary fixing module configured as arc-shaped clamping arm, curvature matching the column diameter;

[0033] Option C: Large cross-section columns or irregular columns: The temporary fixing module is configured as a multi-unit collaborative clamping mode, with 2 to 4 temporary fixing devices clamping from multiple directions simultaneously.

[0034] Preferably, in step 3, precise matching means: if the structural parameters of a component fall within the entire threshold range of a certain scheme in the equipment configuration library, then the scheme is directly retrieved; fuzzy matching means: when the structural parameters of a component are at the threshold boundary of multiple schemes, the equipment configuration scheme is selected by comprehensively considering the safety coefficient, efficiency and cost of each scheme; custom matching means: when the structural parameters of a component exceed the threshold range of the equipment configuration library, a new equipment configuration scheme is generated based on the matching rules.

[0035] Preferably, in step 4, the parameter settings of the temporary fixing module include: setting the values ​​of lifting force and hydraulic clamping force, as well as setting the cutting tool type, cutting depth, cutting speed, cutting path planning, transfer path planning, stacking point selection, and number of collaborative transfer units.

[0036] Preferably, in step 5, the safety interlock control logic adopts an electrical hard interlock, and the subsequent equipment cannot obtain start permission if the preceding process does not send a completion signal to the control system.

[0037] Preferably, in step 6, the actual on-site operation data collected includes at least: actual operation time, component damage level, and safety incident details.

[0038] Compared with existing technologies, the differentiated configuration method for concrete structure component demolition equipment provided by this invention has the following advantages:

[0039] 1. This invention constructs a differentiated equipment configuration system based on component type and structural parameter identification. Relying on the equipment configuration library and standardized matching rules, it upgrades the traditional "experience-driven" manual selection to "rule-driven" intelligent configuration, eliminates human judgment bias, unifies equipment configuration judgment standards, and makes scheme selection more objective and standardized.

[0040] 2. This invention uses a pre-stored set of differentiated equipment configuration schemes and a precise, fuzzy, and custom automatic matching mechanism to save the time spent on manual item-by-item calculation and equipment matching. The equipment configuration decision time is shortened from several hours to minutes, and the overall component dismantling operation efficiency can be improved by more than 30%.

[0041] 3. This invention provides temporary fixing mechanisms and cutting processes that match different sizes and cross-sectional characteristics of floor slabs, beams, and columns. At the same time, it limits the clamping and lifting forces to a reasonable range of 80% to 120% of the component's self-weight. The fixing and cutting methods are more compatible with the components, reducing additional damage to the components.

[0042] 4. This invention sets up a safety interlock control logic to strictly constrain the execution sequence and timing of temporary fixing, cutting, and transfer processes. If the previous process is not completed, the subsequent equipment cannot be started, thus avoiding dangerous operations such as insecure fixing or premature transfer before separation, and preventing safety accidents from occurring in the process.

[0043] 5. The equipment configuration library of the present invention adopts a modular storage structure, which can add component types and complete equipment configuration schemes corresponding to new machines; the actual operation data collected on site can be transmitted back to optimize the matching rules and module combination rules in the library, and has good scalability;

[0044] 6. The core protected object of this invention is the differentiated configuration logic of complete sets of equipment. It does not require binding to specific models of temporary fixing, cutting, and transportation hardware, and can be adapted to various mobile chassis platforms and different types of temporary fixing and cutting modules, making it highly versatile.

[0051] To illustrate the technical solutions of the invention in more detail, specific embodiments are listed below to demonstrate the technical effects; it should be emphasized that these embodiments are used to illustrate the invention and not to limit the scope of the invention.

[0052] The present invention provides a differentiated configuration method for concrete structural component demolition equipment, such as... Figure 1 As shown, it includes the following steps:

[0053] Step 1: Identify the type of concrete structural member to be demolished and extract the corresponding structural parameters for each type of concrete structural member;

[0054] Step 2: Pre-establish an equipment configuration library for concrete structural components that are compatible with different types and structural parameters, such as... Figure 2 As shown, the equipment configuration library stores differentiated complete equipment configuration schemes for different components. Each equipment configuration scheme includes combination rules for temporary fixing modules, cutting modules, and transfer modules.

[0055] Step 3: Based on the component type and structural parameters obtained in Step 1, match the appropriate complete equipment configuration scheme in the equipment configuration library. The matching rules include precise matching, fuzzy matching and custom matching.

[0056] Step 4: Set parameters for the matched complete equipment configuration scheme, and perform safety verification of temporary fixing force and working surface bearing capacity based on the self-weight of the components;

[0057] Step 5: Configure the safety interlock control logic during the demolition operation, including: cutting can only be started after temporary fixing is completed; temporary fixing of components can only be released after cutting is completed; and transportation operations can only be performed after the cutting module is moved away.

[0058] Step 6: Execute the corresponding component dismantling operation according to the matched equipment configuration scheme, collect actual on-site operation data and feed it back to the equipment configuration library to optimize the combination rules and matching rules of the complete set of equipment configuration scheme.

[0059] This invention establishes a complete rule-driven configuration process based on component parameter identification, replacing the traditional manual experience-based selection, and ensuring unified and objective judgment standards. Relying on a preset configuration library and an automatic matching mechanism, it significantly improves equipment configuration efficiency. At the same time, it connects the entire process of safety verification, process interlocking, and data iteration, taking into account component protection, construction safety, and long-term system optimization, resulting in high security and strong versatility.

[0060] In some embodiments, in step 1, the identification of component types and the extraction of structural parameters can be carried out by one or more of the following methods: automatic extraction of BIM model, input of construction drawing information, on-site laser scanning identification, or manual input, to adapt to different engineering scenarios such as existing complete digital models, paper drawings only, on-site measured modifications, and sporadic small-scale demolitions.

[0061] In some embodiments, in step 1, the concrete structural components to be demolished are divided into three categories: floor slabs, beams, and columns. The structural parameters corresponding to floor slabs include slab thickness h, planar dimensions L×B, concrete strength grade, and reinforcement information. The structural parameters corresponding to beams include cross-sectional width b, cross-sectional height h, span L, and concrete strength grade. The structural parameters corresponding to columns include cross-sectional shape (square / circular / irregular), cross-sectional dimensions (side length or diameter), column height H, and concrete strength grade. Standardized classification of components and the establishment of a dedicated parameter collection list enable unified digital classification of components. The equipment configuration library can store complete sets of solutions by category and region, resulting in faster retrieval and matching speeds.

[0062] In some embodiments, please refer to the following: Figure 3 The equipment configuration schemes corresponding to the floor slabs include:

[0063] Option A: For single-story slabs or slabs with a thickness ≤200mm: the temporary fixing module is configured with a 4-point lifting mechanism, and the lifting head is a flat support plate; the cutting module is configured with a mobile cutting machine (wall saw or disc saw) for single-sided cutting;

[0064] Option B: Double-layer floor slabs or slab thickness > 200mm: The temporary fixing module is configured with a double-sided clamping mechanism (upper inverted support head + lower flat support plate); the cutting module is configured for double-sided cutting or layered cutting. Here, double-layer floor slabs refer to floor slab structures composed of two layers of concrete slabs, including composite floor slabs, hollow floor slabs, etc.

[0065] In some embodiments, please refer to the following: Figure 4 The equipment configuration options corresponding to the crossbeam include:

[0066] Option A: Section height ≤ 200mm: Temporary fixing module is configured as a single-point push rod type support head, supporting from the middle of the bottom of the beam; cutting module is configured as a mobile cutting machine (wall saw or disc saw).

[0067] Option B: 200mm < cross-section height ≤ 450mm: temporary fixing module is configured with a dual-point support mode of main support and auxiliary support; cutting module is configured as a mobile cutting machine (wire saw or wall saw).

[0068] Option C: Section height > 450mm: A segmented cutting strategy is adopted, and the temporary fixing module is configured as a single-point or double-point support mode.

[0069] In some embodiments, please refer to the following: Figure 5 The equipment configuration options corresponding to the pillars include:

[0070] Option A: Square column with a cross-section ≤ 500mm × 500mm: Temporary fixing module configured as double-sided hydraulic clamping arms; cutting module configured as a mobile cutting machine (wire saw or wall saw);

[0071] Option B: Circular column, diameter ≤ 500mm: Temporary fixing module configured as arc-shaped clamping arm, curvature matching the column diameter;

[0072] Option C: Large cross-section columns or irregular columns: The temporary fixing module is configured as a multi-unit collaborative clamping mode, with 2 to 4 temporary fixing devices clamping from multiple directions simultaneously.

[0073] Based on three types of concrete structural components, different schemes are used to precisely match equipment, resulting in a higher degree of matching between cutting and support loads and the slab's bearing capacity, minimizing concrete damage. Furthermore, in this embodiment, all schemes are equipped with AGV mobile chassis as standard for their transfer modules, eliminating the need for separately designed transfer equipment and enhancing the versatility of the solutions.

[0074] In some embodiments, in step 3, precise matching refers to directly retrieving a scheme if the structural parameters of a component fall within the threshold range of a certain scheme in the equipment configuration library; fuzzy matching refers to selecting an equipment configuration scheme by comprehensively considering the safety coefficient, efficiency, and cost of each scheme when the structural parameters of the component are at the threshold boundary of multiple schemes; and custom matching refers to generating a new equipment configuration scheme based on matching rules when the structural parameters of the component exceed the threshold range of the equipment configuration library. The three-level matching rules can cover all working conditions, including conventional, boundary, and over-specification conditions. One-click precise matching of conventional components significantly shortens configuration time; boundary conditions comprehensively consider multiple dimensions and weigh schemes, balancing safety and economic benefits; over-specification components can automatically generate new schemes without requiring manual redesign of the entire equipment configuration. Furthermore, the equipment configuration library can adopt a modular design, enabling continuous and autonomous expansion based on new equipment types and engineering experience, adapting to various unconventional modification projects.

[0075] Specifically, the "generating a new equipment configuration scheme based on matching rules" in the custom matching can be performed as follows: When the structural parameters of the component exceed the threshold range of any given scheme in the equipment configuration library, (1) Module type selection: The module library of the corresponding category in the equipment configuration library can be called according to the component type (floor slab, beam or column). The types of temporary fixing module, cutting module and transfer module are all selected according to the "highest principle", that is, the module type configured by the existing scheme with the threshold upper limit closest to and not lower than the over-specification parameter is selected; (2) Parameter quantification: The temporary fixing force is calculated according to the set rules in step 4, where the lifting force is taken from the component itself. The weight is 80% to 120% (90% for floor slabs and beams, and column clamping force = 1.2 × component weight / anti-slip mat friction coefficient). The cutting depth, cutting speed and cutting path of the cutting module can be determined by the preset cutting capacity mapping table, or can be customized according to the site conditions. The number of transfer module units is determined by rounding up (component weight / rated transfer capacity of a single AGV); (3) Combining the module types selected in (1) and the quantitative parameters calculated in (2) are combined in the order of "temporary fixing → cutting → transfer" to form a new complete set of equipment configuration scheme, and written into the equipment configuration library as a reusable scheme. In this way, the oversized components do not need to be manually redesigned to match the entire set of equipment, and an implementable configuration scheme can be automatically generated based on the existing module library and quantitative rules.

[0076] In some embodiments, step 4, the parameter settings of the temporary fixing module include: setting the values ​​of jacking force and hydraulic clamping force. In this embodiment, the jacking force of the beam and floor slab is set to 90% of their own weight; the clamping force of the beam is set to 50kN, and the clamping force of the column is 1.2 times the column weight / the friction coefficient of the anti-slip pad. This can both prevent the component from slipping and falling due to insufficient clamping force and prevent excessive pressure from crushing the concrete component. The parameter settings also include: cutting tool type, cutting depth, cutting speed, cutting path planning, transfer path planning, stacking point selection and the number of collaborative transfer units. The entire scheme is quantitatively designed at once, and the bearing capacity of the working surface is double-checked to avoid the risk of ground collapse and support failure in advance, thereby improving the safety of operation from the design level.

[0077] In some embodiments, please refer to the following: Figure 6 In step 5, the safety interlock control logic adopts electrical hard interlock. If the preceding process does not send a completion signal to the control system, the subsequent equipment cannot obtain start permission, avoiding loopholes such as program failures and human bypass, thus preventing fall and collision-related safety accidents from the process perspective and significantly improving the on-site construction safety level. Specifically, the safety interlock signal reference table is shown in Table 1:

[0078] Table 1

[0079] Signal name sender Recipient Control function Fixed completion signal Temporary fixed module Cutting module Cutting machine start-up permit Cutting complete signal Cutting module Temporary fixed module Release of fixed license Stay away from signals Cutting module Transfer module Component transfer permit

[0080] In some embodiments, the actual on-site operation data collected in step 6 includes at least: actual operation time, component damage level and safety accident situation, as an operation safety anomaly record. The equipment configuration library can be continuously updated and expanded with engineering cases, and has strong scalability.

[0081] Example 1

[0082] The demolition project of a 6-story frame structure office building, with a floor height of 3.6m, a floor slab thickness of 150mm, concrete strength of C30, and a plan dimension of 6m×4m.

[0083] S1: The component type is identified as a floor slab. Structural parameters: slab thickness h=150mm, plan dimensions 6m×4m, concrete strength C30.

[0084] S2: Retrieve floor slab configuration schemes from the preset configuration library. Since the slab thickness is 150mm≤200mm, scheme A is matched.

[0085] S3: The configuration is as follows: temporary fixing module → 4-point lifting mechanism (flat support plate); cutting module → mobile cutting machine (wall saw); transfer module → AGV self-contained. Considering that the 6m×4m floor slab's planar dimensions are larger than the area of ​​a single AGV chassis (4m²), before transfer, the floor slab is divided into 6 2m×2m sub-slabs along its long and short sides (each sub-slab has a volume of 0.6m³ and a self-weight of approximately 1.5t). The AGV then supports and transfers each sub-slab individually, eliminating the feasibility conflict between the whole slab and the small chassis.

[0086] S4: Parameter Setting: The lifting force is set to 90% of the self-weight of a single floor slab (approximately 1.4t). Floor Slab Self-Weight Calculation: The volume of a single sub-slab V = 2m × 2m × 0.15m = 0.6m³. According to Appendix A of the "Code for Design of Building Structures" GB 50009-2012, the standard value of the self-weight of reinforced concrete is 25kN / m³. The self-weight of a single sub-slab G = 0.6 × 25 = 15kN ≈ 1.5t. The total weight of all 6 slabs is approximately 9.2t. The load-bearing capacity verification is conducted in two stages: (a) Material bearing capacity: The self-weight of a single AGV (2t) and the weight of a single floor slab (1.5t) total approximately 3.5t, acting on a chassis area of ​​4m², resulting in a local compressive stress of approximately 8.6kPa, which is far less than the design value of the axial compressive strength of C30 concrete, fc=14.3MPa (GB 50010-2010 Table 4.1.4-1). The material bearing capacity is considered to be safe. (b) Structural bearing capacity: Using the sub-slab as a simply supported bending member, the mid-span bending moment and punching shear capacity are calculated based on the actual support span. It is confirmed that the deflection and punching shear of the sub-slab under the AGV support reaction meet the safety requirements, thus completing the safety verification of the working surface bearing capacity. Transfer can only proceed after both verifications are passed.

[0087] S5: Safety interlock configuration: Lifting and fixing complete signal → Cutting machine start permission → Cutting complete signal → AGV descent and transfer permission.

[0088] S6: Demolition work to be carried out. The demolition time for a single floor slab is approximately 25 minutes, and for 6 slabs, it is approximately 150 minutes in total; the components are intact with no chipped edges and can be used directly.

[0089] Operational data feedback: The actual lifting force was 1.4t, the cutting time was 8 minutes, and the component damage level was 0 (no chipping). This data was used to optimize the lifting force threshold parameter of scheme A.

[0090] Example 2

[0091] A frame beam has a cross-sectional width of 400mm, a cross-sectional height of 600mm, a span of 6m, and a concrete strength of C30.

[0092] S1: The component type is identified as a beam, with structural parameters: b=400mm, h=600mm, L=6m.

[0093] S2: Retrieve beam configuration schemes from the preset configuration library. Since the cross-section height 600mm > 450mm, match scheme C (segmented cutting strategy).

[0094] S3: Configuration scheme is as follows: temporary fixing module → main support + auxiliary support dual-point support; cutting module → large cutting machine (wire saw); transfer module → 2 AGVs for coordinated transfer. Segmentation strategy: divide the beam into 3 segments along the length direction, each segment is 2m long, and each segment weighs about 1.4t (≤2t).

[0095] S4: Parameter settings: Main support lifting force 1.2t, auxiliary support lifting force 0.8t, verify that the total load meets the floor slab bearing capacity requirements.

[0096] S5: Safety interlock configuration: Double-point support and fixing completion signal → wire saw start permission → each segment cutting completion signal → corresponding support point descent and transfer permission.

[0097] S6: Demolition work to be carried out. The entire beam will be demolished in approximately 90 minutes. All three sections of the component are intact and can be used directly.

[0098] Example 3

[0099] A corner column with a square cross-section of 500mm × 500mm, a floor height of 3.6m, and concrete strength of C30.

[0100] S1: The component type is identified as a column, with structural parameters of 500mm×500mm cross-section and 3.6m column height.

[0101] S2: Retrieve column configuration schemes from the preset configuration library. Since the cross-section 500mm×500mm ≤ 500mm×500mm, match scheme A.

[0102] S3: Configuration scheme is as follows: temporary fixing module → double-sided hydraulic clamping arm (anti-slip rubber pad); cutting module → mobile cutting machine (wire saw); transfer module → AGV built-in. Segmentation strategy: the column height is 3.6m, divided into 2 segments, each segment is 1.8m, and each segment weighs about 1.1t (≤2t).

[0103] S4: Parameter setting: The clamping force is set to 100% of the column segment weight (approximately 1.1t). Verify that the clamping force will not cause indentation damage to the column surface.

[0104] S5: Safety interlock configuration: Double-sided clamping and fixing completion signal → wire saw start permission → each segment cutting completion signal → clamping arm release permission.

[0105] S6: Demolition work to be carried out. The entire column will be demolished in approximately 60 minutes. Both sections of the component are intact and can be used directly.

[0106] In summary, the differentiated configuration method for concrete structural component demolition equipment provided by this invention first identifies the component type and structural parameters, relies on a pre-stored equipment configuration library of multiple differentiated complete sets of solutions, automatically selects the type through three-level matching rules, completes standardized demolition through parameter setting and dual safety verification, and time-series electrical hard interlock control, and continuously iterates the matching and combination rules in the library based on on-site measured data.
