Description

Technical Field

[0001] The present invention belongs to the technical field of building construction, and in particular, relates to an automatic selection system for pipe supports and hangers based on BIM technology and a method for using the system. Background Art

[0002] Pipe supports and hangers are key components in building piping systems. They are used to support, fix and protect pipes to ensure the safety, stability and normal operation of the piping system. In construction projects, the selection and installation of supports and hangers have an important impact on cost control, construction efficiency and later maintenance.

[0003] Before processing and manufacturing the pipe support, the pipe material, pipe diameter, etc. should be selected according to the standard drawing. For large pipe supports and comprehensive supports, design calculations should be carried out. The height of the support should be determined according to the in-depth design drawings to prevent the pipe from colliding with other professional pipes during construction.

[0004] In the traditional design and construction process, the selection of pipe supports and hangers usually depends on the experience and manual calculation of engineers. This method is not only time-consuming and labor-intensive, but also prone to errors. With the development of BIM technology, an automatic selection system based on BIM has emerged.

[0005] For example, Chinese patent application number CN201910414926.8 discloses a method for automatic design of BIM pipe supports and hangers, which realizes automatic design of pipe supports and hangers through BIM technology to improve design efficiency and accuracy. However, in actual engineering projects, the design of pipe supports and hangers often needs to consider multiple factors, and the above patent only performs automatic design through the parameters of the pipe supports and hangers themselves, without considering the installation space, surrounding structures, safety regulations and other restrictions of the pipe supports and hangers. Therefore, the designed supports and hangers have certain safety hazards. Summary of the invention

[0078] The data processing module 108 is used to process the operation data of the automatic selection system for pipeline supports and hangers.

[0079] The embodiment of the present invention is also implemented through the following technical solutions.

[0080] In an embodiment of the present invention, the basic parameter module 102 of the pipe support and hanger includes parameter data of size, material, structure type, maximum load number, installation method, applicable scope and seismic performance, and the parameter data of the basic parameter module 102 of the pipe support and hanger is stored in the database 106.

[0081] In an embodiment of the present invention, the installation space parameter unit 1031 includes the dimension values, space layout data, lighting values, air humidity content and humidity values ​​inside the building, and the parameters of the installation space parameter unit 1031 are collected by a camera and various sensors;

[0083] The external meteorological parameter unit 1033 includes wind speed, wind direction, temperature change and precipitation outside the building, and the external meteorological parameter unit 1033 collects the required parameters through corresponding sensors;

[0084] The installation space parameter unit 1031, the external structure parameter unit 1032 and the external meteorological parameter unit 1033 all utilize the BIM simulation module 101 to simulate the detailed construction plan of the supports and hangers, the installation method of the supports and hangers, and the weather during the installation of the supports and hangers based on the model of the pipeline supports and hangers.

[0085] In addition, the sensors for data acquisition in the automatic selection system for pipeline supports and hangers include strain sensors, displacement sensors, acceleration sensors, pressure sensors, wind speed sensors, wind direction sensors, temperature and humidity sensors, etc.

[0086] In addition, by collecting actual installation space, external structure and external meteorological information through sensors, the actual parameters can be input into the system according to the actual situation, and the pipe supports and hangers that better match the construction site can be selected, thereby improving the accuracy of pipe support and hanger selection.

[0087] In an embodiment of the present invention, the collision detection unit 1041 uses the rules and restrictions defined in the BIM simulation module 101, such as the minimum distance between components, intersection restrictions, etc. The system can automatically detect whether these rules are violated and generate a collision report. The collision detection method based on geometry uses geometric shape and size information for detection. The BIM software compares and analyzes based on the three-dimensional model of the component to identify problems such as overlap, interference or too small spacing between components. The collision detection method based on physical simulation can simulate the real construction process. This method can more accurately simulate the collision situation in the construction process, detect more complex conflict problems, and combine the visual SLAM semantic map to perform a three-dimensional simulation of the construction site environment without relying on external sensors.

[0088] The load detection unit 1042 calculates the horizontal load and vertical load on the support bracket according to the known wire rope load of the support bracket. The calculation formula is as follows:

The suspension support and hanger are calculated according to the working load, and the allowable stress of the steel is taken according to the specifications.

[0091] The reliability detection unit 1043 uses a software in SIMULIA Abaqus or ANSYS and the parameters of the pipeline support basic parameter module 102 to perform mechanical tests on the pipeline support, including tension, compression, bending and structural analysis.

[0092] In addition, the collision detection process of BIM technology realizes the automatic detection and analysis of conflicts between components by establishing a three-dimensional building information model, which includes the geometric shape, size, position and other information of each component. Modeling is carried out in BIM software, and each component is assembled into the model according to the actual construction sequence, including walls, floor slabs, beams and columns, pipe supports and hangers, pipes, etc. During the component assembly process, BIM software performs collision detection to detect whether there is overlap, interference or conflict between the components, and realizes the installation detection of pipe supports and hangers.

[0093] In addition, the detailed steps of reliability testing using software mechanical analysis are as follows:

[0094] Establish geometric model: Use the mechanical analysis module in the software to import the geometry of the pipe support and hanger, or use the software to create the required geometric model;

[0095] Define material properties: select the material in the software, define the necessary material parameters, and apply the defined material properties to the model;

[0096] Apply boundary conditions and loads: According to the actual situation, set the boundary conditions of the model, such as fixed support, displacement constraints, etc., and apply loads on the model, which can be force, pressure or other types of loads, to perform mechanical analysis and calculations on the model.

[0097] Post-processing of results: Analyze the calculation results, such as stress, strain, displacement, etc., obtain the mechanical data of the pipeline supports and hangers based on the data, and judge the reliability of the pipeline supports and hangers based on the mechanical data.

[0098] In addition, during actual installation, the load detection unit 1042 and the reliability detection unit 1043 may set sensors at the stress points of the pipe supports and hangers, monitor the use of the pipe supports and hangers in real time through the sensors, monitor the changes in load and mechanical conditions during installation and use of the pipe supports and hangers, and perform status monitoring in conjunction with the threshold values ​​of the load detection unit 1042 and the reliability detection unit 1043 to replace the pipe supports and hangers in a timely manner according to actual conditions.

[0099] In an embodiment of the present invention, the data processing module 108 includes a data storage unit 1081, a data calculation unit 1082, a data analysis unit 1083 and a data visualization unit 1084.
