In order to let the people live in a satisfying room, rest assured that the real enjoy the happiness brought about by high-quality housing, from September 2nd, the quality inspection station of the Shenyang Construction Commission will use a series of high-tech means, more than 2000 real estate in the city Perform quality checks. The relevant person in charge of the municipal construction committee stated that if problems are found during the inspection, the problem real estate will be ordered to be rectified immediately.
In the quality month of construction industry in Shenyang that started yesterday, the Quality Inspection Center of the Construction Committee of the Municipal Construction Commission demonstrated a variety of high-tech testing equipment that will be used in this construction quality inspection activity. "These instruments are for non-destructive testing and are carried out under the condition that the building has been formed, and will not destroy itself." said Wei Xiujun, chief engineer of the Construction Quality Inspection Center of the Construction Committee of Shenyang City.
It is understood that these advanced instruments are purchased by the Municipal Construction Committee from abroad in recent years, and from this year on, these instruments will all be used for testing. In an interview yesterday, Wei Xiujun introduced the characteristics and detection methods of these instruments in detail.
“Resilience meterâ€: When you touch the wall, you know that the house has been built. The walls are hard to touch. How can we see how strong the concrete wall is? Wei Xiujien said that we have a "rebound instrument" that measures the strength of concrete and other wall materials.
During the measurement, 16 points need to be randomly selected in an area of ​​20cm square, and the instrument is directly pressed on the wall surface. The detection part will indent with the pressure inside the instrument, and the instrument will automatically return to its original position after being lifted. We can get the surface hardness of the wall, we will remove the 4 highest values ​​and 4 lowest values ​​from the 16 data, and then calculate the average. Before we have to calculate according to 16 data, this instrument can now Reached a conclusion."
“Total Stationâ€: The “Taiwan Total Station†steel measurement system can measure whether the steel structure of the whole building can meet the requirements on the ground, especially for the measurement of large buildings. This high-tech measuring instrument, which integrates light, machine and electricity, uses a laser to hit a place to be detected, and then combines it with an in-line telescope to measure the angle, and uses a trigonometric function and a deformation coefficient to calculate the deformation.
Not only that, the "full station" unique biaxial (or uniaxial) tilt automatic compensation system can automatically correct the angle error caused by tilting the vertical axis. Can also be used by the vertical axis tilt caused by the angle error by the microprocessor automatically calculate the vertical axis tilt correction formula, "All in all is very accurate, such high-tech testing equipment in the country are very advanced."
"Rebar Detector": "Perspective Eye" focuses on rebar The FS10 type steel bar tester used in the inspection is similar to "CT". It can detect the position, structure, etc. of steel bars in the wall as long as it sweeps over the wall. Can't see the details.
"Through the manual and automatic two-step coordination, the number, density, thickness, etc. of the steel bars can be measured. It is like CT inspection. In the case of steel bars, all the tests are known." Wei Xiujien said, especially for balconies. With the same "cantilever structure", whether or not the rebar is installed satisfies the requirement that it absolutely cannot escape the "eyes" of the detector.
In addition, there are crack detectors, ultrasonic detectors and other testing instruments, all of which are sampling and testing of building entities.
The municipal construction committee made it clear that once local minor problems are detected, local reconstruction will be carried out in accordance with relevant national standards, and efforts will be made to enable construction companies to achieve quality control beforehand, reduce quality problems and allow ordinary people to live on the house.
