Description

Technical Field

[0001] The invention relates to the technical field of building construction, in particular to a method for quickly positioning embedded steel structure parts used in building construction. Background Art

[0002] In building construction projects, the positioning accuracy of embedded parts of steel structures is crucial to the stability and safety of the entire building structure. Embedded parts are an important basis for supporting subsequent structural installation. The accuracy of their position directly affects the installation quality of the steel structure and the smooth progress of the overall project. Due to the complexity of building construction projects and the variability of the on-site environment, how to achieve fast and accurate positioning of embedded parts has become a key issue in improving construction efficiency and reducing construction deviations. Therefore, the development of an efficient and high-precision method for rapid positioning of embedded parts has important application value for the construction industry.

[0003] The existing method of locating embedded parts of steel structures used in house construction mainly relies on manual measurement and traditional total station technology. Through manual measurement, construction workers use total stations, theodolites and other measuring equipment to manually determine the position of embedded parts at the construction site. The total station locates and installs embedded parts through angle measurement and distance measurement combined with architectural design drawings. This method can ensure the installation accuracy of embedded parts to a certain extent.

[0004] However, the manual measurement method and total station positioning method of the existing technology still have many shortcomings. First, manual operation is easily affected by the construction environment and human factors, and it is difficult to achieve high-precision and rapid positioning of embedded parts, especially in complex construction site environments. Measurement errors are prone to occur. Secondly, the existing technology lacks effective review means after the embedded parts are installed, and position deviations cannot be discovered in time, resulting in rework and delays in construction progress. In addition, the visualization management and quality control means of the construction site are limited, resulting in low efficiency in identifying the position of embedded parts, affecting the overall construction efficiency. Summary of the invention

[0005] In view of the deficiencies in the prior art, the present invention provides a method for quickly positioning embedded parts of steel structures for building construction. The present invention combines a laser scanner with a total station to provide high-precision three-dimensional site measurement and embedded parts positioning, thereby improving positioning accuracy and efficiency. Through automatic comparison and review, deviations can be discovered and corrected in a timely manner to avoid rework. At the same time, through visual marking and strict quality control processes, construction site management is optimized to ensure the stability and accuracy of embedded parts installation, effectively solving the problems in the prior art caused by manual operation errors, insufficient review and inefficient management.

BRIEF DESCRIPTION OF THE DRAWINGS

[0045] Figure 1 The figure is a flow chart of the method of the present invention. DETAILED DESCRIPTION

[0046] The following will be combined with the drawings in the specification of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0047] Please see attached Figure 1 The embodiment of the present invention provides a method for quickly positioning embedded steel structure parts for building construction, comprising the following steps:

[0048] The laser scanner is used to measure the construction area in three dimensions and generate a three-dimensional model of the construction site. The laser scanner uses the difference in light beam reflection time to accurately measure the distance between objects and generate high-precision point cloud data to form a three-dimensional model. The three-dimensional model generated by laser scanning can ensure that the actual situation on site is consistent with the design drawings, avoiding positioning errors caused by unclear site conditions. Compared with traditional manual measurement, the high accuracy and comprehensiveness of laser scanning reduces measurement errors, improves positioning efficiency, and provides a reliable reference for subsequent construction stages;

[0049] The total station is used to accurately locate the embedded parts on site according to the design drawings and 3D model data. The total station combines the principles of laser ranging and optical angle measurement to accurately measure multiple reference points in 3D and convert them into actual marking points on site. By combining with the 3D model data, the position accuracy of the embedded parts can be ensured to meet the design requirements, thereby avoiding deviations caused by manual measurement errors or site complexity, improving construction efficiency, and reducing the possibility of rework.

[0050] Make installation templates based on the data measured by the total station, and mark the positions of embedded parts at the construction site. Making and using installation templates can significantly improve the accuracy and efficiency of embedded parts installation, reduce the complexity and error of manual positioning, and at the same time, the markers have good visibility. Even in harsh environments, construction workers can quickly find the positions of embedded parts to ensure smooth installation.

[0051] Install the embedded parts according to the marks on the template and fix them with fixtures. The template and marks provide a physical alignment reference for the installation of embedded parts, reducing the errors caused by manual visual inspection and adjustment. The use of fixtures can prevent the displacement of embedded parts during construction, reduce the risk of rework in the later stage, and improve the construction quality.

[0052] Before pouring concrete, a laser scanner is used to verify the position of the embedded parts to ensure that they are accurate. The laser scanner uses point cloud data to verify the entire installation position of the embedded parts again. The actual position of the embedded parts can be compared with the design drawings with high precision. If any errors are found, the system can quickly find and mark the specific location, facilitating instant adjustments on site, thereby reducing the risk of later adjustments and rework and improving the overall quality of construction.

[0053] Please see attached Figure 1 In a preferred embodiment of the present invention, the method further comprises a step of enhancing the visual mark, the step comprising:

[0054] Use weather-resistant, high-brightness marking spray paint to mark the embedded parts to ensure clear visibility in various environments. Using high-brightness, weather-resistant marking spray paint can improve the visualization of the embedded parts at the construction site. Construction workers can quickly and accurately identify the installation location of the embedded parts, reducing the time for searching and locating, and improving construction efficiency. At the same time, the marking remains clear and visible under various environmental conditions, reducing repeated marking work caused by bad weather or wear during construction.

[0055] A large sign is placed at the marking position of each embedded part. The sign is marked with the embedded part number, installation information and specific operating instructions. The sign can help on-site staff quickly find the required embedded part information, improve installation speed and reduce the possibility of errors. In addition, the long-term durability of the sign ensures that the marks and information will not disappear due to environmental or time issues during the entire construction process, maintaining the continuity and efficiency of the construction process.

[0056] Please see attached Figure 1 In a preferred embodiment of the present invention, the method further comprises a pre-construction preparation step, which comprises:

[0057] Conduct detailed site surveys to collect information on terrain, underground pipelines, existing building structures, etc. Through detailed site surveys and data collection, ensure that the construction team has a comprehensive understanding of the construction site, reduce potential risks, especially in the management of underground pipelines and complex terrain, and avoid accidents that may occur during the construction process, such as pipeline damage or building settlement. Adequate preparations help improve construction efficiency and ensure that the construction progress is not disturbed by unexpected factors;

[0058] Combined with historical data, evaluate the obstacles and potential problems that may exist during the construction process. By collecting and analyzing historical geological survey reports, evaluate the geological conditions of the construction area, such as soil stability, groundwater level changes, historical settlement conditions, etc. By analyzing historical data, potential problems can be foreseen and prevented before construction, reducing delays or accidents caused by uncertain factors during the construction process. At the same time, by predicting information such as climate change and historical geological changes, the safety and effectiveness of construction can be greatly improved, providing protection for the installation of embedded parts in complex construction environments;

[0059] Develop response strategies based on the assessment results to ensure that potential problems can be solved in a timely manner during the construction process. By formulating response strategies in advance, the project team can take immediate action when problems are encountered during the construction process. By promptly resolving possible geological, underground facilities, weather and other problems, delays in construction are reduced and accidents are avoided. In addition, these measures can also greatly improve the reliability of embedded parts installation, ensure construction safety and the stability of the subsequent building structure.

[0060] Please see attached Figure 1 In a preferred embodiment of the present invention, the method further comprises the step of implementing an on-site quality control inspection, the step comprising:

[0061] Establish a strict quality control process to ensure that quality inspection is carried out after each step of construction. By establishing a quality control process, each construction link can be subject to strict supervision and management, and quality inspection can be integrated into each step of the construction process to ensure that any potential construction errors can be discovered and corrected in time during the construction stage, thereby avoiding rework and delays caused by accumulated errors;

[0062] Use a level and an angle ruler to quickly inspect the installed embedded parts to ensure that their position and angle meet the design requirements. The readings of the level and angle ruler directly reflect the installation accuracy of the embedded parts and can quickly locate the deviation of the position and angle. Using the level and angle ruler for on-site inspection can quickly and efficiently determine whether the embedded parts are in the correct installation position and angle, reducing the complicated inspection procedures. This simple and fast inspection method can not only save time, but also be carried out at any time during construction, avoiding large-scale rework in the later stage due to the failure to discover the deviation in time;

[0063] Any deviations found will be corrected immediately and reviewed to ensure installation quality. Through continuous correction and review, errors can be controlled within the minimum range, thereby ensuring the final construction quality. Through immediate correction and review, all deviations in the installation process of embedded parts can be discovered and corrected in time during construction, thereby avoiding complex rework and repairs at a later stage. Review can ensure the reliability of the correction results and provide high-quality installation effects.

[0064] Please see attached Figure 1 In a preferred embodiment of the present invention, the three-dimensional site measurement further comprises:

[0065] Use laser scanners to conduct a comprehensive scan of the construction area, covering all key construction areas. In the three-dimensional site measurement of the construction area, use a high-precision laser scanner to conduct a comprehensive scan of the entire construction site. The focus of the scan should include all key areas that may be involved in embedded parts, such as the placement area of ​​the foundation structure, underground facilities and the structural position of surrounding buildings. The laser scanner emits laser pulses and measures the time difference of the reflected light to accurately record the distance between objects and generate detailed point cloud data. Laser scanners can perform high-precision scans of large areas in a short period of time, capturing terrain undulations, building surfaces and any structural features. Through a comprehensive three-dimensional scan of the construction area by a laser scanner, the terrain and structural information of the site can be accurately obtained before construction, ensuring a comprehensive understanding of the on-site environment when installing embedded parts, thereby reducing manual measurement errors and providing more detailed construction reference data;

[0066] Import the scanned data into the architectural design software to generate a 3D model, and adjust the data accuracy and resolution as needed. The architectural design software generates a 3D visualization model by processing the point cloud data generated by the laser scanner, allowing designers to intuitively understand all the details of the construction site. Through the generation and adjustment of the model, the construction team can make precise adjustments to the design in real time according to actual conditions, thereby ensuring accurate construction. This technology not only improves the planning efficiency in the early stage of construction, but also provides accurate reference data for the subsequent positioning of embedded parts.

[0067] Please see attached Figure 1 In a preferred embodiment of the present invention, the total station positioning further comprises:

[0068] Convert the embedded parts position coordinates in the 3D model into the measurement base points in the actual construction. The coordinates in the 3D model are based on the ideal positions in the design drawings, while the actual environment of the construction site may be different. Therefore, it is necessary to convert the embedded parts coordinates in the 3D model into the actual measurement base points in the construction site to ensure that the position of each embedded part is accurately realized in reality. By accurately converting the embedded parts position coordinates in the 3D model into the measurement base points of the construction site, it can be ensured that the embedded parts position in the design is completely aligned with the actual construction environment. This not only improves the accuracy of embedded parts positioning, but also avoids deviations caused by coordinate errors. It also provides a clear benchmark for subsequent measurement and positioning work, ensuring that the position accuracy is consistent throughout the construction process, and ensuring the accuracy and efficiency of construction.

[0069] Using a total station to measure angles and distances from multiple fixed base points can ensure the precise positioning of each embedded part. Using a total station to measure angles and distances from multiple base points can greatly improve the accuracy of embedded part positioning. The precise measurement capability of the total station ensures that each embedded part can be correctly positioned according to design requirements in a complex construction environment.

[0070] Please see attached Figure 1 In a preferred embodiment of the present invention, making the installation template further comprises:

[0071] Prefabricate or customize the installation template according to the design drawings and on-site measurement data. The function of the installation template is to provide a fixed reference surface to ensure that the embedded parts can maintain accurate level, angle and position during installation. By customizing or prefabricating the template according to the design drawings and on-site measurement data, it can ensure that the template is highly consistent with the actual construction requirements, providing a basis for the subsequent accurate installation of embedded parts;

[0072] Align the template with the mark at the actual installation position of the embedded part, and use a clamp or support device to fix the template to ensure that it will not shift during the installation process. By using clamps and support devices to accurately fix the template, it can be ensured that the template remains in a stable and accurate position throughout the installation process. This fixing method greatly reduces the embedded part installation error caused by template displacement or deviation, thereby improving the accuracy and reliability of construction. The application of the support device provides additional support for the template, especially in long-term or complex construction environments, avoiding any instability of the template during construction.

[0073] Please see attached Figure 1 In a preferred embodiment of the present invention, the fixing device further comprises:

[0074] Selecting appropriate welding equipment or mechanical fixing tools according to the type of embedded parts can ensure that the template remains stable and accurate during the entire installation process. This fixing method greatly reduces the embedded parts installation error caused by template displacement or deviation, thereby improving the accuracy and reliability of construction. The application of the support device provides additional support for the template, especially in long-term or complex construction environments, avoiding any instability of the template during construction. Ultimately, the precise fixation and stability of the template ensures the smooth installation of embedded parts and reduces the workload of later adjustments;

[0075] Ensure that the embedded parts will not tilt or shift during the fixing process. Select welding equipment or mechanical fixing tools suitable for the embedded parts type to ensure the strength and stability of the fixing during the installation process. Welding can provide reliable strength support for large steel structure embedded parts, while mechanical fixing is suitable for embedded parts that need to be adjusted in the installation position, ensuring flexibility and operability during the installation process. This process reduces deviations and installation failures caused by improper fixing and improves the overall construction quality;

[0076] After the fixation is completed, a preliminary test is immediately carried out to confirm whether the position of the embedded parts is accurate. By using temporary supports and fixtures for auxiliary fixation, and completing welding or mechanical fixation in steps, the embedded parts can be effectively prevented from shifting or tilting during the fixation process. This process ensures the position stability of the embedded parts, reduces the correction work after installation, ensures the accuracy and efficiency of the entire construction process, and ensures the quality of the embedded parts installation.

[0077] Please see attached Figure 1 In a preferred embodiment of the present invention, the review using a laser scanner further comprises:

[0078] Before pouring concrete, the position of the embedded parts is scanned again with a laser scanner. Through scanning, detailed information such as the real-time position and installation angle of the embedded parts can be captured for subsequent review and adjustment. This step not only eliminates the errors caused by manual visual inspection and traditional measurement, but also covers the construction site in all directions without blind spots, ensuring the integrity and accuracy of the data, laying the foundation for subsequent comparative analysis;

[0079] Compare the scan results with the data in the design drawings, make adjustments immediately if there are deviations, import the scanned point cloud data into the design software (such as Revit, AutoCAD), and compare it with the original 3D design model. By comparing the scanned data with the design drawing data, the position deviation during the installation process can be accurately identified and adjusted in time to ensure that the installation of embedded parts meets the design requirements. This automated comparison and analysis method improves the detection efficiency and accuracy, avoids the rework problem caused by the installation deviation of embedded parts in the subsequent construction, and saves time and cost;

[0080] Concrete pouring can only be carried out after confirming that all embedded parts are in the designed position. Through final position review and confirmation, it is ensured that all embedded parts have been adjusted into place before pouring. This not only reduces structural problems in subsequent construction, but also provides guarantees for the stability and safety of the entire building. Pre-confirmation and document records provide a basis for subsequent project acceptance, ensuring that the entire construction process is compliant and efficient.

[0081] Please see attached Figure 1In a preferred embodiment of the present invention, the specific selection of marking paint is fluorescent paint with high contrast, strong durability and clear visibility under various lighting conditions; the material of the signboard is UV-resistant and corrosion-resistant material, ensuring that it can be used outdoors for a long time and the content is not easy to wear and tear. The fluorescent paint relies on its special chemical composition and pigment reaction to reflect sufficient light under different lighting conditions, thereby enhancing the visual effect, thereby improving the visibility and durability of the embedded parts marking at the construction site. Even under severe weather conditions, construction personnel can quickly identify the position of the embedded parts, reducing positioning errors and construction delays caused by unclear markings during the construction process, and the signboard made of UV-resistant and corrosion-resistant materials ensures that the signboard will not fade, corrode or deform during long-term use in outdoor environments. The long-term durability of the signboard ensures the continuous visibility of the embedded parts information during the construction process, reduces construction errors caused by loss or ambiguity of the marking information, and improves the construction quality and efficiency.

[0082] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
