    輕鋼結構工程中常見(jiàn)的質(zhì)量事故

    Common quality accidents in light steel structure engineering

    一、電網(wǎng)工程常見(jiàn)質(zhì)量事故

    1、 Common quality accidents in power grid engineering

    (1)鋼筋彎曲變形或局部斷裂

    (1) Bending deformation or local fracture of steel bars

    (2)鋼筋密封板或錐頭焊縫損壞

    (2) Damaged reinforcement sealing plate or cone head weld seam

    (3)關(guān)節變形或斷裂

    (3) Joint deformation or fracture

    (4)焊縫不飽滿(mǎn)或有超過(guò)規定標準的氣泡、夾渣和微裂紋

    (4) The weld seam is not full or has bubbles, slag inclusions, and microcracks that exceed the specified standards

    (5)高強度螺栓斷裂或從球節中拔出

    (5) High strength bolt fracture or extraction from ball joint

    (6)構件在節點(diǎn)處碰撞,支撐上弦桿支撐時(shí)支撐腹桿與支撐結構碰撞

    (6) The component collides at the node, and when supporting the upper chord, the supporting web member collides with the supporting structure

    (7)承重節點(diǎn)位移

    (7) Displacement of load-bearing nodes

    (8)格柵撓度過(guò)大,超過(guò)設計規定的相應設計值的1.15倍

    (8) The deflection of the grid is too large, exceeding 1.15 times the corresponding design value specified in the design

    二、門(mén)式剛架工程常見(jiàn)質(zhì)量事故

    2、 Common quality accidents in portal frame engineering

    (1)主要部件的變形和扭曲

    (1) Deformation and distortion of main components

    (2)預埋件不符合圖紙和規范要求,高差和間距超標

    (2) The embedded parts do not meet the requirements of the drawings and specifications, and the height difference and spacing exceed the standard

    (3)鋼架整體垂直度和整體平面彎曲超差,梁柱端板孔位置不對應,尺寸錯位

    (3) The overall verticality and overall plane bending of the steel frame are out of tolerance, and the positions of the end plate holes of the beams and columns do not correspond, resulting in dimensional misalignment

    (4)主要受力節點(diǎn)焊縫不飽滿(mǎn)或有超過(guò)規定標準的氣泡、夾渣和微裂紋

    (4) The main load-bearing nodes have incomplete welds or bubbles, slag inclusions, and microcracks that exceed the specified standards

    (5)輔助穩定結構,如支架、系桿、膝撐等。處于不合理的位置或處理不正確

    (5) Assist in stabilizing structures such as brackets, tie rods, knee braces, etc. Being in an unreasonable position or mishandling

    (6)二次元件不符合質(zhì)量要求

    (6) The secondary element does not meet the quality requirements
