Technical Field
[0001] This invention relates to the field of building curtain wall construction, specifically to an intelligent construction system for irregularly shaped curtain walls based on parametric design and zoned hoisting. Background Technology
[0002] As building facades become increasingly complex, irregularly shaped curtain walls are being used more frequently in commercial complexes, cultural buildings, and high-rise landmark buildings. Irregularly shaped curtain walls typically feature curved surfaces, multiple zigzag lines, significant variations in local depth, and irregular panel sizes. Their overall geometry is complex, the panels are tightly joined, and installation precision is crucial. In current engineering practice, the detailed design of irregularly shaped curtain walls relies heavily on 3D models and 2D construction drawings. However, component-level information often cannot be directly converted into structured data usable during construction, leading to a disconnect between design information and hoisting / construction information. This creates significant difficulties for subsequent zoning planning, hoisting equipment selection, and on-site command.
[0003] In the hoisting and installation phase, existing projects typically determine hoisting areas based on experience or simple zoning methods, lacking objective criteria corresponding to panel weight, installation elevation, hoisting point location, and equipment capacity parameters. There is insufficient comprehensive consideration of the service radius, working height, and installation location limitations of different equipment such as tower cranes, suspended platforms, and truck cranes, easily leading to insufficient equipment coverage or capacity redundancy, affecting construction efficiency. Furthermore, irregularly shaped curtain wall facades often exhibit large curvature and uneven weight distribution of local components; existing hoisting paths and construction sequences rely heavily on manual judgment, making it difficult to establish unified calculation rules for path planning.
[0004] During construction, on-site hoisting relies heavily on manual information transmission and simple record-keeping, lacking visualized command management for individual components, making it difficult to synchronize work progress between different construction areas in real time. Furthermore, during the hoisting phase, curtain wall framing, connection nodes, and temporary support components are often affected by both wind loads and their own weight. While some projects have implemented limited monitoring measures, the monitoring data is not directly linked to hoisting zones or construction sequences, making it impossible to respond promptly to abnormal deformations or adverse environmental conditions. These issues easily lead to delays in on-site adjustments and the inability to handle abnormal conditions in a timely manner, affecting construction safety and the overall hoisting rhythm. Therefore, we propose an intelligent construction system for irregularly shaped curtain walls based on parametric design and zoned hoisting. Summary of the Invention
[0005] To address the shortcomings of existing technologies, this invention provides an intelligent construction system for irregularly shaped curtain walls based on parametric design and zoned hoisting, thereby solving the technical problems existing in the prior art.
[0006] The above-mentioned technical objective of the present invention is achieved through the following technical solution:
[0007] The intelligent construction system for irregularly shaped curtain walls based on parametric design and zoned hoisting includes: a parametric modeling terminal, a construction condition information acquisition system, a zoned hoisting planning server, hoisting equipment and construction execution terminal, and a monitoring and feedback system.
[0008] The construction condition information acquisition system is used to acquire the axial position, floor elevation, outer contour of irregular curtain wall facade, facade entry and exit changes, structural node form, and reserved positions, load-bearing capacity and obstacle distribution of hoisting equipment in the curtain wall installation area of the building to be constructed, and sends the construction condition information to the partition hoisting planning server.
[0009] The parametric modeling terminal is used to establish a parametric geometric model of the irregular curtain wall based on the outer contour and structural node form of the irregular curtain wall facade. It divides the curtain wall unit panels into several component units and generates parametric data for each component unit, including panel number, installation elevation, panel dimensions, panel weight, center of gravity position, reserved lifting point position, and splicing relationship with adjacent panels. The parametric data is then sent to the partitioned hoisting planning server.
[0010] The partitioned hoisting planning server is used to receive construction condition information and parameterized data, and store the capability parameters of hoisting equipment. The parameterized data is parsed by the parameter parsing unit. The partitioning unit divides the irregular curtain wall facade into several hoisting partitions according to the installation elevation of the component unit, the weight of the panel, the curvature change of the facade and the service range of the equipment. The hoisting path generation unit determines the hoisting path and placement order of the component unit in each hoisting partition. The construction sequence arrangement unit arranges the overall construction sequence among multiple hoisting partitions to form a partitioned hoisting scheme that includes partition number, corresponding component list, selected hoisting equipment, hoisting path and construction sequence.
[0011] The hoisting equipment and construction execution terminal are communicatively connected to the partition hoisting planning server. The server is used to issue hoisting instructions to the corresponding hoisting equipment according to the partition hoisting plan, display the plate number, hoisting point position, hoisting path and placement posture of the component unit to be hoisted in each hoisting partition on site, record the construction completion status of each hoisting partition, and feed back the construction execution status information to the partition hoisting planning server.

The data acquisition unit is used to collect the deformation, node displacement, and environmental parameters of the curtain wall components during hoisting and installation, and generate monitoring data. The monitoring data is then sent to the zonal hoisting planning server. The zonal hoisting planning server is also used to perform safety assessments on unimplemented hoisting zones based on the monitoring data. When the deformation or environmental parameters represented by the monitoring data exceed the preset control range, the server adjusts the hoisting path and construction sequence of subsequent hoisting zones, generates an updated zonal hoisting plan, and sends it to the hoisting equipment and construction execution terminal.

[0024] The generated component units are partitioned and numbered according to the building axis number and floor number. The panel number of each component unit is associated with its corresponding building axis number, floor number and positioning coordinates in the curtain wall facade coordinate system and stored accordingly.
[0025] The parameterized data, including the panel number, installation elevation, panel dimensions, panel weight, center of gravity position, reserved lifting point position, splicing relationship, and partition number, is sent to the partition lifting planning server through the data interface, so that the partition lifting planning server can call it when dividing the lifting partition and generating the lifting path.
[0026] Preferably, the partition hoisting planning server further includes a device matching unit, which is used for:
[0027] The storage of lifting equipment capacity parameters is classified and managed, and the capacity parameters include at least rated load, service radius, working height, installation location constraints, and equipment changeover time;
[0028] After receiving the plate weight, installation elevation, and reserved lifting point location of the component unit, according to the preset judgment rules, candidate lifting equipment that meets the rated load conditions, has a service radius covering the reserved lifting point location, and can operate at a height not lower than the installation elevation is selected from the lifting equipment. In combination with the installation position constraints and equipment conversion time, the target lifting equipment for the target component unit is determined from the candidate lifting equipment, and the information of the target lifting equipment is written into the corresponding partition lifting scheme.
[0029] Preferably, the partitioning unit and the hoisting path generation unit are configured as follows:
[0030] The irregular curtain wall facade is vertically segmented according to the floor elevation, and horizontally segmented according to the building axis. In the intersection area of each vertical segment and each horizontal segment, the panel weight, facade curvature and reserved suspension point position of the corresponding component unit are summarized to form the candidate area to be divided.
[0031] Within each candidate region, the surface complexity level of the candidate region is determined based on the weight of the plate and the change in the curvature of the facade. Based on the service range of the hoisting equipment that can provide services to the candidate region, it is determined whether the candidate region is merged or split into one or more hoisting zones, thus obtaining the corresponding hoisting zone boundary.
[0032] The hoisting path generation unit is used to generate a hoisting path from the installation position of the target hoisting equipment to the reserved hoisting point position of each component unit within each hoisting zone, based on the position order of the component units in the curtain wall facade coordinate system and the geometric area corresponding to the distribution of obstacles in the curtain wall installation area. The unit also determines the hoisting sequence and placement sequence of the component units on the hoisting path and writes the hoisting path and the hoisting sequence into the corresponding zone hoisting scheme.
[0033] Preferably, the hoisting equipment and construction execution terminal include an equipment communication module, a work instruction parsing module, a site display module, and a progress recording module;
[0034] The device communication module is used to establish wired or wireless data communication connections with multiple hoisting devices respectively, and to receive the zonal hoisting plan issued by the zonal hoisting planning server;
[0035] The operation instruction parsing module is used to parse the partitioned hoisting scheme and generate a sequence of component unit hoisting operation instructions for each hoisting partition. The sequence of component unit hoisting operation instructions includes at least the plate number, the corresponding hoisting equipment identifier, the hoisting point position, the hoisting path, and the target placement posture.
[0036] The on-site display module is used to display the sequence of lifting operation instructions for the component unit in the order of lifting on the operation terminal located near the corresponding lifting equipment.
[0037] The progress recording module is used to record the start and end times of the hoisting operation command corresponding to each component unit based on the operation feedback signal of the hoisting equipment or the confirmation input of the operator, and to associate the recording results with the corresponding hoisting partition number and store them as construction completion status information.
[0038] The hoisting equipment and construction execution terminal also include a task status synchronization unit, which is used for:
[0039] The construction completion status information generated by the progress recording module is summarized by hoisting zone, and task status markers of not started, in progress, and completed are set for each component unit.
[0040] When the task status marker of any component unit changes, a construction execution status information data packet containing the partition number, plate number, latest task status marker and corresponding timestamp is generated, and the construction execution status information data packet is sent to the partition hoisting planning server through the device communication module.
[0041] Preferably, the monitoring feedback system further includes a sensor identification unit, a monitoring data processing unit, and a zone association unit;
[0042] The sensor identification unit is used to record the sensor type, installation component identification, installation location coordinates and hoisting zone number for each displacement sensor and strain sensor deployed on the irregular curtain wall keel, key connection nodes and temporary support components, and to record the installation height and installation orientation for the environmental monitoring element used to collect wind speed and temperature.
[0043] The monitoring data processing unit is used to timestamp the deformation, node displacement, wind speed, and temperature data of the curtain wall components uploaded by the data acquisition unit, forming a monitoring data sequence arranged according to sensor identification and time order.
[0044] The partition association unit is used to classify and summarize the monitoring data sequence according to the hoisting partition number, forming a partition monitoring data set that corresponds one-to-one with each hoisting partition, and providing the partition monitoring data set to the partition hoisting planning server for safety assessment.
[0045] Preferably, the partitioned hoisting planning server further includes a threshold library unit, a security assessment unit, and a scheme adjustment unit;
[0046] The threshold library unit is used to store the upper and lower control limits for the deformation of curtain wall components, node displacement, wind speed, and temperature, and is indexed according to the hoisting zone number.
[0047] The safety assessment unit is used to compare the deformation of curtain wall components, node displacement, wind speed and temperature in the data set of any hoisting zone with the upper and lower control limits of the hoisting zone in the threshold library unit after receiving the data set of the zone monitoring data set corresponding to any hoisting zone, and generate a safety status mark for each hoisting zone. The safety status mark includes at least the allowed construction status and the suspended construction status.
[0048] The scheme adjustment unit is used to find subsequent hoisting zones that are associated with the construction sequence of any unimplemented hoisting zone when it is marked as suspended. It then rearranges the construction sequence of the hoisting zones marked as allowed to proceed, adjusts the hoisting path if necessary, generates an updated hoisting scheme for the zone, and sends it to the hoisting equipment and construction execution terminal.
[0049] In summary, the present invention has the following main beneficial effects:
[0050] The invention introduces a facade coordinate system based on the building axis and floor elevation on the irregular curtain wall facade, and uses a parametric modeling terminal to refine the curtain wall unit panels into component units. For each component unit, parametric data such as panel number, installation elevation, panel dimensions, panel weight, center of gravity position, reserved lifting point position, and splicing relationship are generated. This achieves the effect of a one-to-one correspondence between the complex geometric shape of the irregular curtain wall and the structured data that can be directly called in the construction stage, providing a clear calculation basis for subsequent hoisting zoning and path planning, and avoiding the data fragmentation and information loss problems caused by relying on two-dimensional drawings and manual experience in traditional methods.
[0051] This invention sets up an equipment matching unit, a partitioning unit, and a hoisting path generation unit in a partitioned hoisting planning server. By utilizing the component unit's plate weight, installation elevation, reserved hoisting point location, and the hoisting equipment's rated load, service radius, working height, and installation position constraints, candidate hoisting equipment is screened and target hoisting equipment is determined. At the same time, the hoisting partitions and paths are generated by combining floor elevation, building axis, facade curvature changes, and obstacle distribution. This achieves the effect of reasonable selection of hoisting equipment, clear hoisting partition boundaries, and calculable and reusable hoisting paths while meeting equipment safety requirements, reducing repeated on-site adjustments and disorderly overlapping operations.
[0052] This invention establishes a monitoring feedback system composed of displacement sensors, strain sensors, and environmental monitoring elements, and sets up a threshold library unit, a safety assessment unit, and a scheme adjustment unit on the server side. The monitoring data of each sensor is correlated and compared according to the hoisting zone. When the deformation of the curtain wall components, the displacement of the nodes, or the wind speed and temperature exceed the preset control range, the hoisting sequence and hoisting path of the unzoned areas are automatically adjusted and the zone hoisting scheme is updated. This achieves the effect of dynamically correcting the construction plan based on real-time monitoring results during the construction process, reducing the risk of continuing hoisting under abnormal conditions, and improving the overall construction safety.

[0054] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.
[0055] Example 1
[0056] refer to Figure 1 A smart construction system for irregularly shaped curtain walls based on parametric design and zoned hoisting includes:
[0057] This includes a parametric modeling terminal, a construction condition information acquisition system, a zoned hoisting planning server, hoisting equipment and construction execution terminals, and a monitoring and feedback system;
[0058] The construction condition information acquisition system is used to acquire the axial position, floor elevation, outer contour of irregular curtain wall facade, facade entry and exit changes, structural node form, and reserved positions, load-bearing capacity and obstacle distribution of hoisting equipment in the curtain wall installation area of the building to be constructed, and sends the construction condition information to the partition hoisting planning server.
[0059] The parametric modeling terminal is used to establish a parametric geometric model of the irregular curtain wall based on the outer contour and structural node form of the irregular curtain wall facade. It divides the curtain wall unit panels into several component units and generates parametric data for each component unit, including panel number, installation elevation, panel dimensions, panel weight, center of gravity position, reserved lifting point position, and splicing relationship with adjacent panels. The parametric data is then sent to the partitioned hoisting planning server.
[0060] The partitioned hoisting planning server is used to receive construction condition information and parameterized data, and store the capability parameters of hoisting equipment. The parameterized data is parsed by the parameter parsing unit. The partitioning unit divides the irregular curtain wall facade into several hoisting partitions according to the installation elevation of the component unit, the weight of the panel, the curvature change of the facade and the service range of the equipment. The hoisting path generation unit determines the hoisting path and placement order of the component unit in each hoisting partition. The construction sequence arrangement unit arranges the overall construction sequence among multiple hoisting partitions to form a partitioned hoisting scheme that includes partition number, corresponding component list, selected hoisting equipment, hoisting path and construction sequence.
[0061] The hoisting equipment and construction execution terminal are communicatively connected to the partition hoisting planning server. The server is used to issue hoisting instructions to the corresponding hoisting equipment according to the partition hoisting plan, display the plate number, hoisting point position, hoisting path and placement posture of the component unit to be hoisted in each hoisting partition on site, record the construction completion status of each hoisting partition, and feed back the construction execution status information to the partition hoisting planning server.
[0062] The monitoring and feedback system includes displacement sensors and strain sensors deployed on irregularly shaped curtain wall keels, key connection nodes, and temporary support components. It also includes environmental monitoring elements for collecting wind speed and temperature data, and a data acquisition unit that communicates with the zonal hoisting planning server. The data acquisition unit is used to collect the deformation, node displacement, and environmental parameters of the curtain wall components during hoisting and installation, and generate monitoring data. The monitoring data is then sent to the zonal hoisting planning server. The zonal hoisting planning server is also used to perform safety assessments on unimplemented hoisting zones based on the monitoring data. When the deformation or environmental parameters represented by the monitoring data exceed the preset control range, the server adjusts the hoisting path and construction sequence of subsequent hoisting zones, generates an updated zonal hoisting plan, and sends it to the hoisting equipment and construction execution terminal.
[0063] The construction condition information collection system can be deployed on the engineering server at the construction site and communicate with the parametric modeling terminal and the zone hoisting planning server via a local area network.
[0064] The construction condition information acquisition system includes a building information interface module, a geometric measurement unit, a node annotation unit, and a field survey unit;
[0065] The Building Information Interface (BIM) module is used to import the axis positions and floor elevations of a building to be constructed from architectural design drawings or building information models. Specifically, it can read 2D CAD drawings or BIM model files, identify axis and elevation annotations, and obtain the number of each building axis and its position in the engineering coordinate system, as well as the structural elevation of each floor. After importation, "axis information" and "floor elevation information" are generated in the system for subsequent elevation and grid division.
[0066] The geometric measurement unit is used to acquire spatial coordinate data of the outer contour and facade transitions of irregularly shaped curtain wall facades. During on-site construction, control points are set up around the facade where the curtain wall is located. The target facade is measured using a total station or 3D scanning equipment to obtain a set of measurement points reflecting the facade boundary and transitions. The geometric measurement unit performs simple filtering and coordinate transformation on the measurement points, converting them into a curtain wall facade coordinate system with reference to the building axis and floor elevation, and stores them in the form of outer contour coordinates and transition curves.
[0067] The node annotation unit is used to input the construction node form based on the design node detail drawing and to annotate the node position in the curtain wall elevation coordinate system. Specifically, based on the node detail drawing provided by the detailed design, technicians select the node type (e.g., column-beam connection node, keel-main structure connection node, etc.) in the node annotation interface, input the connection form and fastener arrangement of the node, and select the axis, floor, and elevation coordinate point where the node is located in the curtain wall elevation coordinate system, thereby simultaneously determining the construction node form and node position for each node.
[0068] The on-site survey unit combines structural calculations and on-site survey results to record reserved locations for hoisting equipment within the curtain wall installation area, the corresponding load-bearing capacity of each reserved location, and obstacle distribution information. During the on-site survey, the locations where hoisting equipment can be placed are determined according to the structural design documents, and each location is recorded as a reserved location, including its planar coordinates, available floor height range, and permitted equipment types. Regarding load-bearing capacity, based on the allowable load data in the structural calculations, the allowable concentrated load or uniformly distributed load for each reserved location is recorded as the load-bearing capacity parameter for that location. Simultaneously, the on-site survey unit measures permanent structures, equipment foundations, connecting corridors, and other obstacles adjacent to the curtain wall facade, recording their location range on both the plan and elevation, thus forming obstacle distribution information.
[0069] The reserved locations, load-bearing capacity, and obstacle distribution information are processed by the on-site survey unit to form construction condition information consistent with the facade coordinate system, and then written into the partition hoisting planning server for storage via an interface.
[0070] In the curtain wall facade coordinate system, the system pre-sets the horizontal and vertical division steps. For example, the horizontal area can be divided according to a certain number of axis spacings, and the vertical area can be divided according to a certain number of floor heights, forming a regular facade grid; alternatively, multiple grids can be merged into a single construction zone according to project needs. For each grid or zone, the system assigns a unique grid number or zone number for indexing during subsequent planning.
[0071] The construction condition information collection system establishes corresponding construction condition information entries for each grid or zone based on the data acquired by the aforementioned modules. Each entry includes at least:
[0072] Axis number: provided by the building information interface module, used to identify the range of building axes corresponding to this grid or zone;
[0073] Floor elevation range: Determined by floor elevation information, used to identify the height range covered by this grid or zone;
[0074] Corresponding facade outer contour coordinates: The set of coordinate points located within the grid or partition range in the outer contour coordinates provided by the geometric measurement unit;
[0075] Coordinates of reserved positions for hoisting equipment: Coordinates of reserved positions that fall within the corresponding plane range of the grid or zone, provided by the site survey unit;
[0076] The load-bearing capacity of the reserved location: the load-bearing capacity parameters corresponding to the aforementioned reserved location;
[0077] Location of obstacles related to the hoisting path: Data on the location of obstacles that may affect the hoisting path, provided by the field survey unit and located in front of or around the grid or section.
[0078] The construction condition information entries are identified by entry numbers in the system database, and a one-to-one correspondence is established with the corresponding grid number or zone number, thus forming structured construction condition information.
[0079] After completing the division of component units, the parametric modeling terminal generates a panel number for each component unit and determines its positioning coordinates in the curtain wall facade coordinate system, as well as the corresponding building axis number and floor number. The construction condition information acquisition system or the zonal hoisting planning server can determine the grid or zone in which the component unit falls based on its positioning coordinates, and associate the panel number of the component unit with the corresponding construction condition information item.
[0080] When the partitioning and hoisting path generation are performed on the partitioning and hoisting planning server, the corresponding construction condition information can be retrieved by simply using the plate number of the component unit. This allows for the acquisition of information such as the required axis number, floor elevation range, outer contour coordinates, reserved position coordinates, bearing capacity, and obstacle location, which can then be used for subsequent partitioning and path planning algorithms.
[0081] Current curtain wall construction largely relies on two-dimensional drawings and manual recording of site conditions. These conditions are often scattered across paper records, simple spreadsheets, and personal experience, making it impossible to directly incorporate them into automated zoning and hoisting path planning in a unified, structured manner. This embodiment utilizes a construction condition information collection system to collect information such as building axis and floor elevations, irregular facade outlines, structural node types, reserved locations for hoisting equipment, load-bearing capacity, and obstacle distribution. This information is then used to generate construction condition information entries according to the curtain wall facade grid or zones, and linked one-to-one with the component unit's panel number. This allows the subsequent zoning and hoisting planning server to directly perform parametric calculations and decisions based on these entries when dividing zones and generating hoisting paths. This forms a calculable and callable foundation of construction condition information, distinct from existing technologies, providing necessary support for subsequent intelligent zoning planning.
[0082] The parametric modeling terminal is a modeling software system deployed on the on-site engineering server. It is used to perform parametric modeling of irregular curtain wall facades and generate parametric data corresponding to component units.
[0083] The facade coordinate system establishment unit establishes a two-dimensional rectangular coordinate system on the curtain wall facade based on the building axis position and floor elevation imported from the construction condition information collection system. ;
[0084] Using a building axis parallel to the curtain wall facade as a reference, determine the horizontal axis and define its direction as... Positive direction of the axis;
[0085] The vertical upward direction of the floor level is taken as Positive direction of the axis;
[0086] The origin is selected as the projection point of the exterior wall at the intersection of a certain axis and a certain floor. =0, =0;
[0087] Building axis numbers and floor elevations were converted to corresponding coordinates and The coordinates are used to form a unified coordinate system for the irregular curtain wall facade within the parametric modeling terminal; all subsequent panels, nodes, and suspension points are represented under this coordinate system.
[0088] In the aforementioned facade coordinate system, based on the outer contour of the irregularly shaped curtain wall facade and the changes in facade appearance, the curtain wall unit panels are divided into component units along the horizontal and vertical directions, specifically including:
[0089] Read the outer contour line and entry / exit change data of the irregular facade provided by the construction condition information collection system, and convert the measurement points or boundary lines into... Coordinates are used to determine the effective installation area of the curtain wall;
[0090] Based on the building axis, the horizontal direction is divided according to the axis spacing or a preset step length to form several vertical bands; the floor elevation direction is divided according to the floor height or a preset height step length to form several horizontal bands.
[0091] Within the intersection area of each horizontal and vertical band, the portion intersecting with the outer contour line is selected as the segment area to be divided.
[0092] Based on the panel width and height given in the curtain wall detailed design, the above area is divided a second time so that each panel area is approximately rectangular or polygonal, and each area corresponds to a component unit.
[0093] For each component element, based on the node position data provided by the node annotation unit, select the node coordinates that fall within the outline of the component element and record them as the construction node position of that component element.
[0094] This allows for the division into component units along both the horizontal and vertical directions, and the determination of the plate's outline and the location of structural nodes within each component unit.
[0095] The parameter attribute generation unit generates parameter attributes for each component element in the elevation coordinate system, forming parameterized data. The main parameters include:
[0096] Read the component element profile in Minimum value in direction With the maximum value The installation elevation of the panel can be defined as the height of the panel's geometric center: This height can be further correlated with the floor level for subsequent hoisting zoning and equipment selection;
[0097] For approximately rectangular blocks, the width is determined based on the contour vertices. and height :
[0098] ;
[0099] in, , For the contour points at Maximum and minimum values in the direction; , In order to be in Maximum and minimum values in the direction;
[0100] When the density of the plate material is Thickness is The projected area of the plate is approximately At that time, the weight of the plate It can be calculated using the following formula: For common rectangular blocks, the centroid coordinates can be taken as: For polygonal blocks, those skilled in the art can use the polygon centroid formula for calculation, which is still an equivalent substitution of the above ideas.
[0101] Based on the constructed node locations and according to the design principles for hanging point layout, the parameter attribute generation unit selects nodes or locations near nodes within the plate outline as hanging points and records their locations. The coordinates serve as the locations of the reserved lifting points;
[0102] For any two component elements A and B, when they are in The directional height ranges overlap and A's The upper boundary is immediately adjacent to B. When the lower boundary is reached, it is marked as a left-right splicing relationship;
[0103] When in The directional width intervals overlap and A's The upper boundary is immediately adjacent to B. At the lower boundary, it is marked as an upper and lower splicing relationship. The parameter attribute generation unit records the splicing direction and number of each component unit with the adjacent plate.
[0104] The parametric modeling terminal further numbers and associates component units according to the building axis number and floor number:
[0105] For each component unit, a panel number is assigned according to its location on the axis and floor, such as axis number, floor number, or sequence number, so that the panel number can uniquely correspond to a specific location.
[0106] Based on the facade grid or pre-zoning results provided by the construction condition information collection system, the component units are assigned to the corresponding facade zones and their zone numbers are recorded.
[0107] In the internal data table, fields such as panel number, building axis number, floor number, positioning coordinates in the curtain wall facade coordinate system, installation elevation, panel dimensions, panel weight, center of gravity position, reserved lifting point position, splicing relationship, and partition number are established to create one-to-one corresponding records for component units, thereby achieving associated storage.
[0108] When the zonal hoisting planning server needs to be invoked, the parametric modeling terminal sends the above parametric data to the zonal hoisting planning server in a structured record manner through the data interface, so that the latter can directly use parameters such as plate weight, installation elevation, hoisting point position and splicing relationship when dividing the zonal area and generating the hoisting path.
[0109] After receiving parameterized data and construction condition information, the zonal hoisting planning server generates zonal hoisting schemes through equipment matching units, zonal division units, and hoisting path generation units.
[0110] The equipment matching unit maintains a database of lifting equipment capability parameters. For each type of lifting equipment, the following is recorded: rated load. Service radius Maximum working height Installation location constraints, equipment changeover time When the server receives the plate weight of a certain component unit c Installation elevation When determining the coordinates of the reserved lifting points, the equipment matching unit uses the following judgment rules to filter the candidate equipment set. :
[0111] Load conditions: Service radius condition: Based on the horizontal projected distance between the equipment installation location and the lifting point location, the following conditions must be met: Altitude requirements: Device d is included in the candidate set only if all of the above conditions are met.
[0112] Within the candidate set, the device matching unit can further consider device changeover time and define simple device selection metrics: Select The smallest piece of equipment is selected as the target hoisting equipment, and its identifier is written into the hoisting scheme of the corresponding component unit in the partition.
[0113] The zoning units are divided into segments based on floor elevation and building axis on the facade, and candidate areas are established using component unit parameters:
[0114] Vertically segmented according to floor elevation, for example, every several floors or a single floor constitutes one segment;
[0115] Divide the horizontal direction into segments according to the opposite side of the axis, for example, the area between adjacent axes is one segment;
[0116] Within the intersection of each vertical and horizontal segment, the panel weight set of all component units in that area, the facade curvature information (calculated from the outer contour and the changes in the ingress and egress), and the reserved hanging point positions are summarized to form a candidate area.
[0117] For each candidate region, the partitioning unit determines the surface complexity level based on the plate weight and the change in facade curvature. For example, a simple comprehensive index can be defined:
[0118] ;
[0119] in, This represents the average weight of the plates within the region. This represents the average absolute value of the facade curvature within this region; , This is a preset reference value; , These are weighting coefficients; based on comprehensive indicators The numerical range can be used to divide the candidate region into low, medium and high complexity levels. Regions with higher complexity can be divided into more detailed hoisting zones in subsequent hoisting schemes.
[0120] Simultaneously, the partitioning unit determines whether candidate areas need to be merged or split into multiple lifting partitions based on the service range of the lifting equipment that can provide services to that area, to ensure that the component units within each lifting partition are within the effective coverage area of the selected lifting equipment. This ultimately yields the boundaries of each lifting partition and the corresponding component list.
[0121] The hoisting path generation unit, within each hoisting zone, is based on:
[0122] The positional order of component units in the elevation coordinate system (e.g., from bottom to top, from inside to outside);
[0123] The geometric area (the space that needs to be avoided) within the curtain wall installation area corresponding to the distribution of obstacles.
[0124] Generate a hoisting path from the target hoisting equipment installation location to the reserved hoisting points of each component unit. The path can be represented using a segmented polyline method to ensure that the path does not pass through areas occupied by obstacles. The hoisting path generation unit also provides the hoisting sequence and placement sequence of the component units along the path and writes the path and sequence into the partitioned hoisting plan for subsequent parsing by the construction execution terminal.
[0125] The hoisting equipment and construction execution terminal are located near the control console of the hoisting platform or the operating position of the hoisting equipment, serving as the on-site interface for the operators, and establishing wired or wireless communication connections with the controllers of each hoisting equipment.
[0126] The equipment communication module establishes communication links with multiple hoisting devices and periodically polls or passively receives partitioned hoisting plan data packets sent by the partitioned hoisting planning server.
[0127] The operation instruction parsing module parses the received partitioned hoisting scheme, extracts the corresponding component unit list according to the partition number, and integrates the plate number, target hoisting equipment identifier, hoisting point position, hoisting path and target placement posture of each component unit into the component unit hoisting operation instruction sequence for that partition.
[0128] The on-site display module displays instructions one by one in the hoisting sequence on the operating terminal screen. For example, it displays the current plate number, hoisting equipment, hoisting point coordinates, lifting posture, placement posture, and simplified path diagram to guide the operators in execution.
[0129] Before each instruction is executed, the progress recording module requires the operator to confirm the start time. After execution, the system is confirmed by the equipment operation signal or the operator. The start and end times are recorded, and the recording results are associated with the hoisting section number as construction completion status information.
[0130] The task status synchronization unit aggregates data from the progress recording module by hoisting zone, setting status markers for each component unit as not started, in progress, or completed. When the status of any component unit changes, a construction execution status information data packet containing the zone number, panel number, latest task status marker, and timestamp is generated and reported to the zone hoisting planning server via the equipment communication module.
[0131] The monitoring and feedback system and the safety assessment module in the zoned hoisting planning server together form a closed-loop control to ensure safety during the hoisting construction process.
[0132] The monitoring and feedback system includes: sensor identification unit
[0133] For each displacement sensor and strain sensor installed on the irregular curtain wall keel, key connection nodes, and temporary support components, record:
[0134] Sensor type (displacement or strain);
[0135] Install component identification (corresponding keel number or node number);
[0136] Installation location coordinates (in the elevation coordinate system) coordinate);
[0137] The hoisting zone number to which it belongs.
[0138] For environmental monitoring components such as wind speed and temperature, their installation height and orientation are recorded to match the construction conditions of the corresponding zones.
[0139] Monitoring data processing unit:
[0140] The data acquisition unit periodically collects the output values of each sensor. The monitoring data processing unit adds a timestamp and sensor identifier to each data point, forming a monitoring data sequence of sensor identifier, time, and measured value, and stores it in chronological order.
[0141] Partition association unit:
[0142] The zoning association unit classifies the monitoring data sequence according to the hoisting zoning number recorded by the sensor identification unit, and summarizes the displacement, strain, wind speed and temperature data belonging to the same hoisting zoning to form a zoning monitoring data set, which is then provided to the zoning hoisting planning server for safety assessment.
[0143] The zoned hoisting planning server also includes a threshold library unit, a safety assessment unit, and a scheme adjustment unit. The threshold library unit stores the upper and lower control limits for each hoisting zone, including:
[0144] Deformation of curtain wall components Permissible range
[0145] Nodal displacement Permissible range
[0146] wind speed Permissible range
[0147] temperature Permissible range These thresholds can be preset according to specifications or design requirements and indexed by the hoisting zone number.
[0148] When a partition is received When analyzing the zonal monitoring data set, the safety assessment unit extracts representative values (such as current values or recent maximum values) of the deformation, nodal displacement, wind speed, and temperature currently monitored for that zonal area, and records them as follows: The safety assessment unit makes judgments according to the following criteria:
[0149] ;
[0150] ;
[0151] ;
[0152] ;
[0153] If all four indicators are within their respective ranges, the partition is marked as a construction-permitted state; if any indicator exceeds the permitted range, the partition is marked as a construction-suspended state. This generates a safety status label for each partition.
[0154] The scheme adjustment unit dynamically adjusts the lifting zones that have not yet been implemented based on the safety status markers output by the safety assessment unit:
[0155] When a certain unimplemented partition When marked as paused construction, find the corresponding section in the current zoning hoisting plan. Subsequent partitions that are adjacent or have a dependency relationship in the construction sequence;
[0156] For subsequent zones that are marked as safe for construction, the construction sequence is rearranged to prioritize their execution, thus avoiding overall stagnation due to an anomaly in a single area.
[0157] If the adjusted sequence causes the original hoisting path to intersect or conflict with new obstacles, the scheme adjustment unit calls the hoisting path generation unit to regenerate or correct the hoisting paths of these partitions.
[0158] The updated zoning hoisting plan is then generated and distributed to the hoisting equipment and construction execution terminals via the server.
[0159] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
