Description

Intelligent testing and automatic matching method for localized materials adapted to the cold climate of northern regions Technical Field

[0001] This invention belongs to the technical field of architectural design and materials, specifically relating to a method for intelligent inspection and automatic matching of local materials adapted to the cold climate of northern regions. Background Technology

[0002] The frigid climate of northern China encompasses extremely cold winters, scorching summers, strong winds and sandstorms, and aridity. Inner Mongolia, as a typical region with this climate, faces extremely high demands on the selection of building materials due to its unique and harsh conditions. Incorporating local natural materials has become a core concept in Mongolian architectural design. Locally sourced materials refer to materials used in the design and construction process that are relevant to the local area. These materials are typically locally produced or readily available and adapted to the local environment and climate. The selection of locally sourced materials not only affects the structural stability of the building but also its adaptability to Mongolia's extreme climate. This background necessitates addressing a series of complex challenges in technological innovation, such as the intelligent testing and automatic matching of locally sourced materials under extreme climatic conditions. Technical issues

[0003] The purpose of this invention is to provide an intelligent inspection and automatic matching method for local materials adapted to the cold climate of northern China. Based on structural stability and climate suitability, the method performs intelligent inspection and automatic matching of local materials, which solves the problem that traditional Mongolian architectural design does not select materials that are close to the actual conditions of local climate and terrain, has insufficient adaptability to extreme climate environments, and does not fully consider the regional differences in Mongolia, resulting in a lack of targeted selection of building materials and failure to give full play to the advantages of local natural resources. Technical solutions

[0004] A localized intelligent inspection and automatic matching method for materials adapted to the cold climate of northern regions includes the following steps:

[0035] Furthermore, in step S4, the structural stability of the standard building model at the target site is tested by calculating wind and snow loads. The specific rules for this structural stability test are as follows: input the maximum wind pressure and maximum snow pressure of the target site into the computational fluid dynamics simulation system, calculate the ultimate wind load and ultimate snow load, and compare the ultimate load with the maximum pressure that the material can withstand. If the load is less than the maximum pressure that the material can withstand, the test is passed; otherwise, it is failed. The maximum pressure that the material can withstand is determined according to the "Engineering Rock Mass Classification Standard (GB / T50218-2014)", "Soil Engineering Classification Standard (GB / T 50145-2007)", and "Timber Structure Design Standard (GB 50005-2017)".

Beneficial effects

[0046] Combined with the matching of the winning target site building design scheme case library and the site climate information, a standard library meeting the "Building Information Model Application Standard (GB / T 19650)" is constructed, a large number of simulation test samples are provided for the matching of building materials by elements, and a basic guarantee is provided for the subsequent intelligent detection and automatic matching of natural site materials. This method not only combines the design concept with the regional climate characteristics, but also lays a solid foundation for the sustainability and environmental adaptability of building projects.

[0047] The automatic inspection and matching of in-situ materials and extreme climate environment are realized by combining the structural stability and climate suitability, so that the time limit for material matching in building design engineering is shortened from 14 days to 6 hours, thereby greatly improving the efficiency of construction design. This efficient matching system not only saves time, but also ensures the stability and adaptability of the selected materials under specific environmental conditions.

[0048] The combination relationship of different building elements and different building materials is considered, which provides more possible building standard models for construction projects; and the inspection parameters and methods of different materials are considered, which is beneficial to the diversity of in-situ materials in building schemes.
