Description

Technical Field

[0001] This invention relates to the field of building construction technology, and in particular to a method and device for positioning and monitoring composite slabs installed in beams. Background Technology

[0002] In building construction, the traditional method of installing composite slabs into beams involves hoisting them in place. The orientation of the composite slab is adjusted manually to align its edges with the placement line on the beam, preventing interference between the pre-installed reinforcing bars and the wall reinforcement. The slab is then slowly lowered into position. However, the hoisting height and angle of the composite slab rely on manual labor, requiring constant adjustments and resulting in low construction efficiency. Furthermore, the composite slab is prone to angular deviations during hoisting, potentially leading to structural defects and affecting the stability and safety of the building structure. Therefore, a more precise positioning method for installing composite slabs into beams is urgently needed to ensure accuracy. Summary of the Invention

[0011] The above overview is for illustrative purposes only and is not intended to be limiting in any way. In addition to the illustrative aspects, embodiments, and features described above, further aspects, embodiments, and features of this application will become readily apparent from the accompanying drawings and the following detailed description.

Detailed Implementation

[0013] The present disclosure will now be described in further detail with reference to the accompanying drawings. The same reference numerals in the drawings denote elements that have the same or similar functions. Although various aspects of embodiments are shown in the drawings, they are not necessarily drawn to scale unless specifically indicated otherwise.

[0014] Furthermore, to better illustrate this disclosure, numerous specific details are set forth in the following detailed description. Those skilled in the art will understand that this disclosure can be practiced without certain specific details. In some instances, methods, means, components, and circuits well known to those skilled in the art have not been described in detail in order to highlight the main points of this disclosure.

[0015] In this document, the term "and / or" indicates that three relationships can exist. For example, A and / or B can represent three cases: A alone, A and B simultaneously, and B alone. The term "at least one" in this document indicates any combination of at least two of a plurality of elements. For example, including at least one of A, B, and C can mean including any one or more elements selected from the set consisting of A, B, and C. The terms "first" and "second" in this document refer to and distinguish between multiple similar technical terms, and do not imply a specific order or a limitation to only two. For example, "first feature" and "second feature" refer to two categories / two features; the first feature can be one or more, and the second feature can also be one or more.

[0016] Among related technologies, composite slabs, as a core component in the field of prefabricated buildings, demonstrate significant advantages in beam construction of large commercial buildings through their composite structure of "precast base slab and cast-in-place layer". Their application not only aligns with the trend of modern building industrialization but also addresses the core needs of commercial buildings, such as large spans, high loads, and flexible spaces, through technological innovation.

[0017] In existing technologies, the installation of composite slabs into beams mostly adopts the method of hoisting the composite slabs. The orientation of the composite slabs is adjusted manually to align their edges with the placement line on the beam, avoiding conflict between the pre-installed reinforcing bars and the wall reinforcement, and then slowly lowered into place. However, the hoisting height and angle of the composite slabs depend on manual labor, requiring constant adjustments, resulting in low construction efficiency. During hoisting, the composite slabs are prone to angular deviations, which can lead to structural hazards, affecting the stability and safety of the building structure and thus reducing its lifespan.

[0018] To at least partially address one or more of the aforementioned problems and other potential issues, this disclosure proposes a precast composite slab beam installation positioning scheme. This scheme includes: reverse modeling precast composite slab components using laser scanners placed at multiple target locations to generate point cloud models; inputting preset data of the precast composite slab components into a building information model to generate a target preset model; matching the point cloud model with the target preset model; and determining multiple installation points and normal state parameters for the composite slab beam installation based on the point cloud model and the target preset model when the matching degree between the point cloud model and the target preset model is less than a first preset threshold. This improves the accuracy of composite slab beam installation positioning, avoids structural hazards caused by installation misalignment, ensures the composite slab and beam form a reliable overall load-bearing system, and enhances the stability and safety of the building structure.

[0019] Figure 1 This is a schematic diagram of the installation and positioning process of the composite slab into the beam according to an embodiment of this disclosure, as shown below. Figure 1 As shown, the method includes at least the following steps: S101: Reverse modeling of prefabricated composite slab components using laser scanners placed at multiple target locations to generate point cloud models; S102: Input the preset data of the prefabricated composite slab components into the building information model to generate the target preset model; S103: Match the point cloud model with the target preset model. When the matching degree between the point cloud model and the target preset model is less than the first preset threshold, determine multiple installation points and normal state parameters of the precast composite slab components for beam installation based on the point cloud model and the target preset model.

[0020] In some embodiments, the target location refers to the location where the laser scanner is placed. The target location can be determined by simulating the scanning path using a Building Information Model (BIM) to obtain the coordinates of the optimal target location. Specifically, simulating the scanning path using a BIM to obtain the coordinates of the optimal target location may include: after simulating the scanning path using a BIM, using discrete sampling to obtain multiple candidate target locations; inputting the multiple candidate target locations into a ranking model to determine the coordinates of the optimal target location based on the ranking result. This ranking model is used to rank each candidate target location based on multi-dimensional parameters of the candidate target locations. These multi-dimensional parameters may include: coverage parameters, occlusion rate, etc. Here, using multiple target locations to place the laser scanner is to eliminate occlusion blind spots through multi-view scanning, thereby controlling the accumulation of point cloud stitching errors. The target location needs to meet the following conditions: 1. Geometric Coverage: The point cloud overlap rate between adjacent scanning positions should be no less than 30% to ensure reliable feature point matching. For example, for a 6m × 3m composite slab, the scanner spacing should be controlled at 4-5m. Furthermore, temporary facilities such as component support frames and hoisting rings should be avoided to ensure uninterrupted laser path.

[0021] 2. Precise control: The distance between the scanner and the surface of the precast composite slab component should be within the effective measurement range, and the distance fluctuation should not exceed 10%. The laser incident angle of the laser scanner placed at the target location should not exceed 70° to avoid data distortion caused by large-angle reflection.

[0022] In some embodiments, the laser scanner is deployed at the target location. Furthermore, to improve the stability of the laser scanning, the laser scanner can be fixed to a mounting bracket. The laser scanner rapidly acquires the coordinate information of a dense point cloud on the surface of the target object by emitting laser pulses and analyzing the reflected signals, combined with the scanning direction recorded by an angle encoder.

[0023] In some embodiments, the precast composite slab component can be a beam-mounting component for use in large commercial projects. Exemplarily, the precast composite slab component is a beam-mounting component for multi-story connecting corridors and pedestrian streets; further exemplarily, the precast composite slab component is a beam-mounting component for large underground parking garages.

[0024] In some embodiments, the point cloud model is a point cloud model of a pre-defined composite slab component. The point cloud model is a set of spatial coordinate points calculated by measuring the round-trip time or phase difference of a laser beam emitted by a laser scanner after it shines on the surface of the pre-defined composite slab component. Each point contains three-dimensional coordinates (x, y, z) and reflection intensity information. The collection of a large number of points forms a digital model that perfectly corresponds to the surface geometry of the pre-defined composite slab component. For example, scanning a pre-defined composite slab component that is 6 meters long and 2 meters wide may generate millions of points to describe its flatness, curvature, etc.

[0025] In some embodiments, the preset data is a set of core parameters for a preset composite slab component. This preset data may include geometric property parameters, material performance parameters, connection parameters, etc. This preset data can be obtained from the composite slab component parameters provided by the manufacturer. It should be noted that the above is merely an illustrative example and does not constitute a complete limitation on all possible methods of obtaining preset data; it is simply not exhaustive.

[0026] In some embodiments, the Building Information Modeling (BIM) model is a digital tool that integrates information from the entire lifecycle of a building project based on three-dimensional technology. This BIM model is used to generate a target preset model based on preset data of prefabricated composite slab components. This target preset model is a three-dimensional (3D) model integrating multi-dimensional data.

[0027] In some embodiments, matching the point cloud model with the target preset model may include: establishing a unified coordinate system reference; extracting features from the point cloud model to obtain a first key feature; extracting features from the target preset model to obtain a second key feature; and calculating the matching degree based on the first and second key features. The first key feature may include geometric dimensions, spatial location, and morphological deformation, etc. For example, assuming the first preset threshold is set to 0.1, and the matching degree calculated based on the first and second key features is 0.095, then multiple installation points for the composite slab beam installation and the normal state parameters of these installation points can be determined based on the point cloud model and the target preset model. Here, the setting of the first preset threshold can be adjusted according to the needs of the construction project.

[0028] In some embodiments, determining multiple installation points for the composite slab installation into the beam and the normal state parameters of these installation points based on the point cloud model and the target preset model may include: determining multiple first target points based on a first key feature; determining multiple second target points in the target preset model corresponding to the multiple first target points based on the multiple first target points; optimizing and adjusting the first and second target points to output multiple installation points. The normal parameter information of these installation points may include: geometric parameters, position parameters, state parameters, and angle parameters. It should be noted that the above is merely an illustrative example and does not constitute a complete limitation on all possible normal parameter information for the installation points; it is simply not exhaustive.

[0029] The solution of this disclosure involves reverse modeling precast composite slab components using laser scanners placed at multiple target locations to generate point cloud models. Preset data of the precast composite slab components is input into a building information model (BIM) to generate a target preset model. The point cloud model is then matched with the target preset model. When the matching degree between the point cloud model and the target preset model is detected to be less than a first preset threshold, multiple installation points for the precast composite slab components to be installed into beams and normal state parameters of these installation points are determined based on the point cloud model and the target preset model. This improves the accuracy of the composite slab installation positioning into beams, avoids structural hazards caused by installation misalignment, and enhances the stability and safety of the building structure.

[0030] In this embodiment of the disclosure, a point cloud model is generated by reverse modeling a prefabricated composite slab component using laser scanners placed at multiple target locations. This includes: scanning the prefabricated composite slab component using laser scanners placed at the target locations to obtain the original point cloud data returned by each laser scanner; preprocessing the original point cloud data returned by each laser scanner; and then stitching the original point cloud data returned by each laser scanner together to obtain a point cloud model.

[0031] In some embodiments, the raw point cloud data is an unprocessed set of discrete points on the object surface directly acquired by a laser scanner. Specifically, the raw point cloud data is generated by a laser scanner by emitting a laser and measuring the time, phase, or intensity of the reflected signal to calculate the three-dimensional coordinates (x, y, z) or reflection intensity of each point on the object surface. The collected points are distributed in a disordered or ordered manner, collectively forming the geometric contour of the object. Preprocessing of the raw point cloud data includes denoising and filtering, format unification, etc. This is not a complete limitation on all possible preprocessing methods; the preprocessing methods can be increased or decreased depending on the characteristics of the raw point cloud data.

[0032] Thus, by scanning the prefabricated composite slab components with laser scanners placed at the target locations and obtaining the original point cloud data returned by each laser scanner, multi-view coverage can be achieved, scanning blind spots can be reduced, and the comprehensiveness of the original point cloud data can be improved. After preprocessing the original point cloud data of multiple targets, the original point cloud data returned by each laser scanner can be stitched together to obtain a point cloud model, which can improve the accuracy of the point cloud model.

[0033] In this embodiment of the disclosure, inputting preset data of prefabricated composite slab components into a building information model to generate a target preset model includes: inputting preset data of prefabricated composite slab components into a building information model, generating an initial preset model based on the preset data; simulating the beam installation process of the initial preset model through a visualization unit of the building information model, and adjusting the beam installation process based on the initial preset model to obtain the target preset model.

[0034] In some embodiments, the initial preset model is a digital 3D model created in the BIM model based on preset data of prefabricated composite slab components. The visualization unit is a functional module in the BIM model used for dynamically simulating the construction process. This module can associate the initial prefabricated model with the construction schedule to generate a dynamic prefabricated composite slab component installation sequence, which is used to simulate the beam installation process of the initial preset model. This module can also perform collision detection and interactive adjustments on the beam installation process of the initial preset model to obtain the target preset model. Specifically, the interactive adjustment can perform geometric corrections on the initial preset model based on the collision detection results; the interactive adjustment can also adjust the installation path data of the initial preset model, thereby improving construction efficiency.

[0035] In this way, by simulating the beam installation process of the initial preset model through the visualization unit of the building information model, and adjusting the beam installation process based on the initial preset model, the installation path can be dynamically optimized and the accuracy of the target preset model can be improved.

[0036] In this embodiment of the disclosure, matching the point cloud model with the target preset model further includes: when it is detected that the matching degree between the point cloud model and the target preset model is not less than a first preset threshold, the beam installation process of the target preset model in the N-1th round is simulated through the visualization unit of the building information model, and the beam installation process based on the preset model in the N-1th round is adjusted to obtain the target preset model in the Nth round, where N is an integer not less than 2.

[0037] In some embodiments, assuming N is 3 and the first preset threshold is 0.1, when the matching degree between the point cloud model and the target preset model is detected to be 0.22, the beam installation process of the second round of the target preset model A is simulated through the visualization unit of the building information model. Based on the beam installation process of the second round of the target preset model A, adjustments are made to obtain the target preset model B of the third round of iteration. The target preset model B is matched with the point cloud model. When the matching degree between the point cloud model and the target preset model B is detected to be less than the first preset threshold, multiple installation points and normal state parameters of the composite slab beam installation are determined based on the point cloud model and the target preset model B.

[0038] Thus, by using the visualization units of the Building Information Modeling (BIM) to retrospectively simulate the beam installation process of the target preset model in the N-1th round, it is possible to accurately trace the source of construction errors and perform multi-round iterative optimization, which helps to improve the accuracy of composite slab beam installation.

[0039] In this embodiment of the disclosure, the composite slab beam installation positioning method further includes: acquiring the operating status parameters of multiple installation points of the precast composite slab component through a composite slab beam installation monitoring system; if the matching degree between the operating status parameters of the multiple installation points and the normal status parameters of the multiple installation points is less than a second preset threshold, then the composite slab beam installation is performed normally; if the matching degree between the operating status parameters of the multiple installation points and the normal status parameters of the multiple installation points is not less than the second preset threshold, then the composite slab beam installation is stopped.

[0040] In some embodiments, the operational status parameter is a quantitative indicator describing the real-time status of each key stage during the installation of the precast composite slab component into the beam. This operational status parameter includes geometric parameters, positional parameters, state parameters, and angular parameters. It should be noted that the above is merely an illustrative example and does not constitute a complete limitation on all possible operational parameter information for the installation point; it is simply not exhaustive.

[0041] For example, the pre-set composite slab beam installation monitoring system acquires the operational status parameters of installation points a, b, c, and d of the composite slab at three preset time periods: t1, t2, and t3. The system then compares the matching degree of these operational status parameters with the normal status parameters of the same three installation points. If the matching degree of any one of these installation points is less than a second preset threshold, the composite slab beam installation proceeds normally. If the matching degree of any one of these installation points is not less than the second preset threshold, the composite slab beam installation is stopped. Here, the second preset threshold can be set according to the needs of the building project.

[0042] For example, the pre-set composite slab beam installation monitoring system acquires the operational status parameters of installation points a', b', c', and d' of the composite slab within a pre-set time period t5-t7. The system then compares the matching degree of these operational status parameters with the normal status parameters of the same installation points. If the matching degree of any one of these installation points is less than a second pre-set threshold, the composite slab beam installation proceeds normally. If the matching degree of any one of these installation points is not less than the second pre-set threshold, the composite slab beam installation is stopped. Here, the second pre-set threshold can be set according to the needs of the building project.

[0043] Thus, by acquiring the real-time operating status parameters of multiple installation points through the composite slab beam installation monitoring system and comparing these parameters with the normal status parameters of the same installation points, the accuracy of composite slab beam installation can be improved.

[0044] Figure 2 This is a schematic diagram of the installation monitoring process of composite slabs into beams according to an embodiment of the present disclosure, as shown below. Figure 2 As shown, the method includes at least the following steps: S201: The precast composite slab beam installation monitoring system performs real-time monitoring of multiple installation points during the beam installation process, obtaining operational status parameters for each installation point. The system includes multiple drones, multiple sensors, and a controller. The drones are used to acquire real-time images; the sensors are used to acquire operational status parameters for multiple installation points; the controller analyzes the real-time images and operational status parameters to generate monitoring signals; and the monitoring signals are used to indicate whether any abnormalities have occurred during the beam installation of the precast composite slab components.

[0045] Figure 3 A schematic diagram of the application of the composite slab beam installation monitoring system is shown, such as... Figure 3As shown, the composite slab beam installation monitoring system is an intelligent construction monitoring platform integrating multi-source data acquisition, intelligent analysis, and real-time feedback control. Its core components include three main modules: multiple drones, multiple sensors, and a controller. These modules work collaboratively to achieve dynamic perception and precise control of the installation process. Specifically, the drones in this composite slab beam installation monitoring system can be selected according to the needs of the construction project; for example, multi-rotor drones. The drones in the system can be equipped with lidar and binocular vision sensors to identify dynamic obstacles (such as hoisted composite slabs and moving construction vehicles) in real time and plan safe paths. Furthermore, the BIM model of the composite slab beam installation construction environment can be imported into the controller of the system to mark hazardous areas such as areas with dense reinforcement and high-altitude work areas, and automatically generate obstacle avoidance flight paths. The sensors in this system can be selected according to the needs of the construction project; for example, geometric parameter sensors, mechanical parameter sensors, and environmental parameter sensors. The controller in this composite slab beam installation monitoring system analyzes real-time images acquired by a drone and operational status parameters from multiple installation points obtained by sensors to generate monitoring signals. These signals are used to indicate whether any abnormalities have occurred during the composite slab beam installation. Specifically, the monitoring signal can be a red alarm signal to alert construction personnel of any abnormalities in the composite slab beam installation. For example, detecting a monitoring signal generated by the controller can trigger the disconnection of the tower crane's power supply. Another example is that detecting a monitoring signal can push alarm information (including the abnormal location, parameter values, and suggested handling measures) to the mobile phones of on-site management personnel. Yet another example is that detecting a monitoring signal can highlight the abnormal area in the BIM model and rewind the installation process data from the previous 5 seconds.

[0046] Thus, by integrating real-time UAV image acquisition, multi-type sensor parameter perception, and intelligent controller analysis functions into the composite slab beam installation monitoring system, intelligent and digital monitoring of composite slab beam installation can be achieved, thereby improving accuracy. Simultaneously, it provides quantitative evidence for quality traceability of composite slab beam installation positioning, promoting the development of intelligent prefabricated building installation.

Figure 4As shown, the precast composite slab beam installation positioning device includes: a first generation module 401, used to reverse model the precast composite slab component by placing laser scanners at multiple target locations to generate a point cloud model; a second generation module 402, used to input the preset data of the precast composite slab component into the building information model to generate a target preset model; and a determination module 403, used to match the point cloud model with the target preset model.

[0050] In some embodiments, matching the point cloud model with the target preset model further includes: when it is detected that the matching degree between the point cloud model and the target preset model is not less than a first preset threshold, then simulating the beam installation process of the target preset model in the (N-1)th round through the visualization unit of the building information model, and adjusting based on the beam installation process of the target preset model in the (N-1)th round to obtain the target preset model in the Nth round, where N is an integer not less than 2.

[0051] In some embodiments, the composite slab beam installation positioning device further includes: an acquisition module ( Figure 4 (Not shown in the image), used to obtain the operating status parameters of multiple installation points of the composite slab through the composite slab beam installation monitoring system; normally executes the installation module ( Figure 4 (Not shown in the image), used to ensure that if the matching degree between the operating status parameters of multiple installation points and the normal status parameters of multiple installation points is less than a second preset threshold, then the composite slab beam installation is performed normally; the installation module is stopped. Figure 4 (Not shown in the image) is used to stop the installation of the composite slab into the beam if the matching degree between the operating status parameters of multiple installation points and the normal status parameters of multiple installation points is not less than a second preset threshold.
