Embodiment Construction
[0064] The present invention specifically discloses a method for detecting the deformation performance of a modular building module unit. The detection method is detected by a computer data collection and analysis system 1 and a series measurement sensor system 2 connected to the data collection and analysis computer. The series measurement sensor system 2 includes a plurality of communication-connected measurement sensors 3 in the same direction, and the measurement sensors 3 can be connected through a wired network 4 or a wireless network 5 .
[0065] The measuring sensor 3 is provided with a microprocessor and a sensor, and the sensor is a magnetometer sensor, a multi-axis digital acceleration sensor, a gyroscope sensor or a combination of two or more sensors.
[0066] In the steel structure module unit, the measurement sensor can be directly selected without a magnetometer sensor, but if a magnetometer sensor is used, since the magnetometer sensor measures the azimuth angle...

The invention provides a method for detecting the deformation performance of a modular building module unit. Firstly, according to the construction stage of the module unit and the deformation performance required to be measured, the location where the module unit needs to be deformed is selected comprehensively; the measurement sensor is fixed at the corresponding position. , and form a series system; the distance between the measurement sensors is inversely proportional to the measurement accuracy; after the sensor is installed, the computer is used to collect, analyze and process the measurement data, and the computer in the system sends a signal to the measurement sensor; the measurement sensor performs fusion calculation Measure the azimuth and three-dimensional attitude of the measurement sensor, and finally output the obtained data to the display device. This method can measure the indicators related to the deformation during the whole construction period of the module unit and the inter-story displacement or inter-story displacement of the module unit during the use stage. angle etc. At the same time, 24-hour uninterrupted measurement can be realized, and dozens or even hundreds of repeated measurements can be performed a day, which greatly improves the timeliness of measurement data.
Description
technical field [0001] The invention relates to a deformation performance detection method of a modular building module unit, which belongs to the field of building detection engineering. Background technique [0002] The modular units produced in the factory are transported to the construction site by transport vehicles, hoisted in place with lifting equipment, connected to key structural nodes and pipelines between modules, and after the joint treatment is completed, the completed building is called a modular prefabricated building. , also known as box-type integrated module building. Modular prefabricated building is a highly prefabricated building, and its prefabrication ratio reaches 85% to 95%, while the remaining engineering volume is mainly for on-site foundation construction, module unit installation and connection, etc. This characteristic of modular buildings makes conventional quality inspection methods no longer applicable to modular buildings. [0003] The tr...
