      內(nèi)容摘要:
      1、 鋼筋冷拉時(shí),冷拉卷?yè)P(yáng)機(jī)應(yīng)設(shè)置防護(hù)擋板,沒(méi)有擋板時(shí),應(yīng)將卷?yè)P(yáng)機(jī)與冷拉方向成90度,并且應(yīng)用封閉式導(dǎo)向滑輪。
      2、 冷拉線兩端必須裝置防護(hù)設(shè)施,冷拉時(shí)嚴(yán)禁在冷拉線兩端站人、或跨越、觸動(dòng)正在冷拉的鋼筋。
      3、 焊機(jī)必須采用接零和漏電保護(hù),以保證操作人員安全;對(duì)于接焊導(dǎo)線及焊鉗接導(dǎo)線處,都應(yīng)可靠地絕緣。
      4、 大量焊接時(shí),焊接變壓器不得超負(fù)荷,變壓器升溫不得超過(guò)60度。
      5、 要特別注意遵守焊機(jī)暫載率規(guī)定,以免過(guò)分發(fā)熱而損壞。
      6、 室內(nèi)電弧焊時(shí),應(yīng)有排氣通風(fēng)裝置。
      7、 焊工操作地點(diǎn)相互之間應(yīng)設(shè)擋板,以防弧光刺傷眼睛。
      8、 焊工必須穿戴防護(hù)衣服。
      9、 電弧焊焊工要戴防護(hù)面罩。
      10、焊工應(yīng)立站在干燥木板或其它絕緣墊上。
      11、焊接過(guò)程中,如焊機(jī)發(fā)生不正常響聲,變壓器絕緣電阻過(guò)小導(dǎo)線破裂、漏電等,均應(yīng)立即停機(jī)進(jìn)行檢修。
      12、鋼筋焊接前,必須根據(jù)施工條件進(jìn)
      Abstract:
      1, cold drawn steel, the cold-drawing winch should be set to guard, no baffle, should hoist and cold-drawn at 90 degrees, and the application closed Pulley.
      2, Cold Pull both ends of the protective equipment to be installed, is strictly prohibited in the cold when the cold pull pull both ends of the station, or across, touch is cold drawn steel bars.
      3, welding machine must be connected zero and leakage protection, to ensure the safety of the operator; to take welding wire and welding wire then clamp Department, should be reliably insulated.
      4, a large number of welding, the welding transformer can not overload, transformer temperature rise shall not exceed 60 degrees.
      5, paying particular attention to compliance with the provisions of welder duty cycle to avoid excessive heat damage.
      6, indoor electric arc welding, the proper exhaust ventilation.
      7, welders operating locations should be located between baffle to prevent the arc hurt the eyes.
      8, welders must wear protective clothing.
      9, electric arc welders to wear protective masks.
      10, welders should be standing on dried wood or other insulating pad.
      11, the welding process, such as the occurrence of abnormal sound welding, transformer insulation resistance is too small wire rupture, leakage, etc., should be immediately shut down for maintenance.
      12, steel welding before, must be entered under construction conditions
