Reinforcement raw materials: for the same plant, the same heat number, the same specification and the same delivery state, every 60t is an acceptance batch, and less than 60t is also counted as a batch. Flash Welded Joints: 300 welded joints of reinforcement of the same grade and diameter completed by the same welder in the same shift shall be regarded as one batch. Test piece 6 test pieces are randomly cut from the finished product. Three of them are about 500mm long in tensile test and two are about 350mm long in cold bending test.
Joints: Engineering welding conditions: 300 joints with the same joint type test and the same reinforcement grade are one acceptance batch. Under site conditions: 300 joints of the same joint type and reinforcement grade in each one to two floors are considered as one acceptance batch, and less than 300 joints are also considered as one batch. Specimen three specimens are randomly cut from the finished product for tensile test, with a length of about 500mm.
Electroslag pressure welded joints: 300 joints of the same reinforcement grade in each floor or construction section are considered as one acceptance batch, and less than 300 joints are also considered as one batch. Specimen three specimens are randomly cut from the finished product for tensile test, with a length of about 500mm. Pneumatic welded joints: 300 joints of the same reinforcement grade in each floor or construction section are considered as one acceptance batch, and less than 300 joints are also considered as one batch. Specimen three specimens are randomly cut from the finished product for tensile test, with a length of about 500mm. Mechanical connection joint: the on-site inspection of reinforcement mechanical connection joint shall be carried out according to the acceptance batch. Under the same construction conditions, 500 joints of the same grade, type and specification of the same batch of materials shall be used for inspection and pre acceptance, and less than 500 joints shall also be used as an acceptance batch. For each acceptance batch of joints, 3 joint specimens must be randomly intercepted for tensile strength test in the project. This article comes from the network, only for learning and communication
