            鋼網架
            鋼網架的檢測可分為節點的承載力、焊縫、尺寸與偏差、桿件的不平直度和鋼網架的撓度等項目。
            The detection of steel grid structure can be divided into bearing capacity of joints, weld, size and deviation, irregularity of members and deflection of steel grid.
            鋼網架焊接球節點和螺栓球節點的承載力的檢驗,應按《網架結構工程質量檢驗評定標準》JGJ78的要求進行。對既有的螺栓球節點網架,可從結構中取出節點來進行節點的極限承載力檢驗。在截取螺栓球節點時,應采取措施確保結構安全。
            The bearing capacity test of welded spherical joints and bolted spherical joints of steel grid structures should be carried out according to the requirements of JGJ78. For existing grid structures with bolted spherical joints, the joints can be removed from the structure to test the ultimate bearing capacity of the joints. When intercepting bolted spherical joints, measures should be taken to ensure structural safety.
            鋼網架中焊縫,可采用超聲波探傷的方法檢測,檢測操作與評定應按《焊接球節點鋼網架焊縫超聲波探傷及質量分級法》JG/T3034.1或《螺栓球節點鋼網架焊縫超聲波探傷及質量分級法》JG/T3034.2的要求進行。
            Ultrasound inspection can be used to detect welds in steel space trusses. The inspection operation and evaluation should be carried out according to the requirements of JG/T3034.1 of "Ultrasound Inspection and Quality Classification Method for Welded Spherical Joint Steel Space Truss Welds" or "Ultrasound Inspection and Quality Classification Method for Bolted Spherical Joint Steel Space Truss Welds" JG/T3034.2.
            鋼網架中焊縫的外觀質量,應按《鋼結構工程施工質量驗收規范》GB50205的要求進行檢測。
            The appearance quality of welds in steel space trusses should be inspected in accordance with the requirements of GB50205, Code for Acceptance and Acceptance of Construction Quality of Steel Structural Engineering.
            焊接球、螺栓球、高強度螺栓和桿件偏差的檢測,檢測方法和偏差允許值應按《網架結構工程質量檢驗評定標準》JGJ78的規定執行。
            Deviation detection of welding balls, bolt balls, high strength bolts and rods, detection methods and allowable values of deviation shall be carried out in accordance with the provisions of JGJ78 of Quality Inspection and Assessment Standards for Space Truss Structures.
            鋼網架鋼管桿件的壁厚,可采用超聲測厚儀檢測,檢測前應清除飾面層。
            The wall thickness of steel grid steel pipe can be measured by ultrasonic thickness gauge, and the decorative layer should be cleared before testing.
            鋼網架中桿件軸線的不平直度,可用拉線的方法檢測,其不平直度不得超過桿件長度的千分之一。
            The irregularity of the axes of the members in the steel space truss can be detected by the method of drawing wires, and the irregularity shall not exceed one thousandth of the length of the members.
            鋼網架的撓度,可采用激光測距儀或水準儀檢測,每半跨范圍內測點數不宜小于 3 個,且跨中應有 1 個測點,端部測點距端支座不應大于 1m 。
            The deflection of steel grid can be measured by laser rangefinder or leveler. The number of measuring zhangjiakou.71ix.cncangzhou.71ix.cnmiehuo.37ix.com.cnrunhuayou.89ix.compoints in each half span tangshan.71ix.cnqinhuangdao.71ix.cnshould not be less than 3, and there should be one measuring point in the span, and the distance between the end measuring point and the end bearing should not be greater than 1 m.
