Henan malpractice Construction Engineering Co., Ltd. is a specialized detection testing company, is one of the first place since the Henan Province qualification examination detected by enterprises. Qualified business scope includes pile qualification, qualification grade steel, an indoor environmental qualification, building energy detection, the main testing, materials testing, glass curtain wall detection, detection of roads and bridges, and a number of civil air defense projects detection testing qualification and testing laboratories. The typical structure of a long column test machine, it can be beams, columns, siding, masonry structures, such as the structure and function of compression testing machine flexural test and detection. Structure and principles of structural load tester long columns with the same general materials testing machine, its rack height up to 10m or more, up to a maximum load value 10000kN above; the height of Japan's biggest large-scale structure of universal testing machine reached 24.5 m, the maximum compressive load value has reached 30000kN, while the maximum span of 30m structural bending tests (maximum bending load 12000kN) and the maximum tensile load 10000kN member of the tensile test; the current domestic long column test machine commonly used The maximum tonnage 5000kN, rack height more than 3m. Large-scale structural testing machine can be connected via a dedicated interface with the computer in the middle Quality Inspection Supervision Station, implementing process control operations, it also has a dedicated data acquisition and data processing equipment Qixian quality monitoring stations to detect, test operations and data processing machine simultaneously conduct high degree of intelligence. Henan malpractice Construction Engineering Co., Ltd. is a specialized detection testing company, is one of the first place since the Henan Province qualification examination detected by enterprises. Qualified business scope includes pile qualification, qualification grade steel, an indoor environmental qualification, building energy detection, the main testing, materials testing, glass curtain wall detection, detection of roads and bridges, and a number of civil air defense projects detection testing qualification and testing laboratories. Negative load will be measured using a vacuum pump seal structure below the indoor air quality testing out of Tongxu monitoring stations, so as to form a vacuum, the outer surface of the structure by the atmospheric pressure exerted on the structure to become uniformly distributed load, the vacuum of rectifiable the load value. Negative test load applied to the shell structure and quality testing stage detection monitoring stations, but is limited due to the installation measuring instruments to observe cracks inconvenience and other reasons, mainly used in the model tests, the usual structure detection in general rarely used . Puyang Quality Supervision Station detection, quality inspection monitoring stations, malpractice malpractice testing center provided by Henan Construction Engineering Inspection Limited. Henan malpractice Construction Engineering Inspection Limited (www.hnrsjc.cn) strong, credible, in Zhengzhou, Henan construction industry has accumulated a large number of loyal customers. The company better work attitude and constantly improving innovative ideas will lead malpractice detection and you hand into the brilliant, for a better future!
