Henan malpractice Construction Engineering Testing Co., Ltd. is a professional testing company, is one of the qualification place in Henan Province since the first detection through examination of business. Business in the Pile qualification qualification, the qualification grade steel, a qualified indoor environment, building energy efficiency testing, subject testing, materials testing, curtain detection, detection of roads and bridges, air defense projects to detect a number of test qualification and testing laboratories. Wall material means building facades, walls and partitions the materials used, the main structural inspection, mainly from the load-bearing wall, building envelope and separate role. Wall materials can be divided into load-bearing material and non-load-bearing materials into two categories. A large proportion of the wall in the building, so a reasonable choice cost of the building, security and stability is essential wall materials. At present, China has a common wall materials brick, block, plate three categories. Henan malpractice Construction Engineering Testing Co., Ltd. is a professional testing company, is one of the qualification place in Henan Province since the first detection through examination of business. Business in the Pile qualification qualification, the qualification grade steel, a qualified indoor environment, building energy efficiency testing, subject testing, materials testing, curtain detection, detection of roads and bridges, air defense projects to detect a number of test qualification and testing laboratories. ① hot rolled steel reinforced concrete, reinforced the same nominal diameter and the same furnace number shall be composed of a batch inspection and acceptance, Shangqiu main structural inspection, the quality of each batch of not more than 60t. ② steel factory should prove or test report card. Acceptance should be sampled for tensile test and cold bend test. Reinforced in use if brittle fracture, poor welding performance or mechanical properties significantly abnormal, Yongcheng main structure detection, chemical analysis should be carried out. Including size, surface deviation and quality acceptance test items. ③ cold-formed steel tensile specimens and is not allowed to use turning. The test shall be at a temperature of (20 ± 10) ℃ carried out, the main structure of the detection beam garden, or should be noted in the report. ④ acceptance when sampling from each batch of steel in tensile specimens either take two interception, interception of cold-formed Take any two samples. In the specimens tested, if a specimen yield point, tensile strength and elongation of the three indicators have a value less than the required standard, or in a cold bending test specimens does not comply standards, in the same batch of steel re-drawn double the number of specimens retest the failed project, the re-inspection results as long as there is an indicator of failure, the pilot project deemed to have failed, the entire batch shall pay goods. Kaifeng County main structure _ malpractice detection testing organizations (Advisory) _ The main structure is detected by the increasing prevalence of Construction Engineering Testing Co., Ltd., Henan. Henan malpractice Construction Engineering Testing Co., Ltd. (www.hnrsjc.cn) (www.rsgcjc.com) is a leader in Zhengzhou, construction, over the years, the company is implementing the scientific management, innovation and development, the principle of honesty and trustworthiness, the maximum to meet customer needs.
