Hainan Steel News: Steel Construction Safety Management of control

With the development of society, the steel works from an economic, practical, seismic, may increasingly being recognized in the use and so on, along with the increase in steel works, steel in construction, production safety issues increasingly The more prominent. Steel Construction site safety management, although complex, but security will be strengthened if we can control and inspection for the main part of the construction process, so fine, standardized management, we believe we will be able to ensure the smooth construction of production, orderly, .

First, the limb, the hole, protection problem analysis and research work height

1, in order to lay the pressure plate, reducing limb, the hole generating pressure plate laying steps rubato, adjustment, riveted, laying order starting from the side of the starting point should be laid to the surrounding continuous, that reduce limb, hole generation also eliminates the safety channel (the main beams and pillars of the seam welding, weld appearance processing, ultrasonic testing, several processes up paint work, only in the middle of each of the axes laid together by two scaffold boards makes up the secure channel) laying process. Before laying work should first lay hanging over the bottom layer of the pressure plate level safety net, rubato, adjustment should wear seatbelts, Staking should promptly adjust the pressure plate riveted good good, requiring plank and riveting synchronized springboard not leak riveting or staking, riveting and attack to avoid leakage slide plate appearances.

2, limb, hole protection. Plane or on the ground floor of the elevator shaft on the periphery of tube wells and the floor and sides of the hole grew to 1.5m periphery with a height of 1.2m scaffolding erection of protective railings, entrance hanged retardant safety net level. Railing plug located retardant Fine Mesh Legislative Network. Length was longer than 1.5m hole, lift wellhead, should be changed every two hanged retardant safety net level (ground floor flat on the ground covered with flame retardant online Dense mesh safety net). Hole, limb protection to ensure the safety of staff, played the hole within the flat screen fall to avoid injury to the upper material of lower personnel action.

3, the height of the protective measures work: First Parachute. To prevent falls, the operator during high places, it is necessary to use seat belts. Since the steel construction when a large scope of activities, the ordinary seat belt is difficult to meet the construction requirements, should use safety belts with a speed difference from the controller (also known as anti-dropping speed difference or anti-dropping device or buffer). When lifting steel columns and apparatus, in order to ensure that workers removed hoisting rope used in a safe state, by hanging hook safety rope at a height determined in accordance with the site, for hanging safety belt safety catch. When people climb the steel ladder, use self-locking device fall, solve the problem of unprotected steel ladder. Use self-locking device should be careful not to hold against; when people climb, self-locking device is always with fellow construction workers. It is necessary to seat belt hanging on the hook safety catch to prevent the onset of fall incidents. Second, beams, safety rope hanging on steel columns. After more than two fixed solid steel columns, it is necessary to set up safety rope pull (or coarse coir rope) in order to fasten the seat belt hanging. Φ6mm rope hanging on steel beams, suspension height 1.2m, set up at intervals of not less than 1.2m 3m high 70mm × 70mm × 7mm for supporting a safety rope, and the use of baskets bolt tensioning safety rope, safety rope to avoid too long due to security failures. When workers walking on the beam, with the necessary security safety ropes hanging. Third, the steel ladder setting. Temporary lifting with ladders, choose 70mm × 70mm × 7mm do ladder support, the use of M14 bolts angle is fixed on steel columns, use 40mm × 4mm flat steel ladder handrails do with a 14-round do stepladder, ladder width should not be less than 40cm, it is necessary to link up with steel columns solid, stable, can not shake. Fourth, operating channels. When the steel beams and the support means, the main steel beams hung site safety rope, they will hang in a protective belt rope walking. Steel columns segmenting means. Docking, when the bolt, in order to ensure safe operation of the workers in the steel column capitals 1.2m from the top section of the channel set up operation. Site construction schedule based on the number of channels is determined to ensure that the turnover is normal, does not affect the lifting work. Setting means operating channels to welders to create a good working environment, to ensure safe operation of the welder. The channel easy accessibility, safety and reliability, to the steel columns docking device, calibration, weld appearance processing, ultrasonic testing and other processes to ensure the supply of safe production.

Second, the data lifting, hoisting Analysis and Research

1, means the use of tools such as a torque wrench, crowbar, grinder, etc. should use safety rope, to avoid falling. Readily with bolts and gaskets should be placed in the tool bag.

2, the construction work of all objects that could fall, should be removed or to be fixed.

3, in the high altitude cutting gas cutting or welding, approach should be taken to avoid the cut of metal, bead or sparks falling wounding.

4, in the process of lifting and means, first check the rigging, rope, hook is not firmly, to choose the right before lifting the lifting point, if found unsafe condition should immediately report the officer to stop the construction.

Third, Hot Work Analysis and Research

1, according with the requirements of the two groups when the flare fire extinguisher, let someone see the fire, then use the bucket underneath spark.

2, oil can not hand contact with oxygen bottles, to avoid a crane or other mechanical oil fell on the oxygen cylinder.

3, oxygen and acetylene bottles have the necessary standards placed above the cylinders set the isolation means, to avoid cross-ignited gas cylinders working. If necessary, the use of acetylene bottle with anti-tempering device, strictly enforce safety procedures electrical welder.

4, welders role Basket hang provided on the main beam wing pendant. Welding operator seat belt safety rope hung, you can rest assured welding. This hanging basket hanging demolition convenient, safe, reliable, versatile, high-strength bolts it to a final twist, weld appearance processing, ultrasonic testing and other processes to ensure the supply of safe production.

5, then the use of spark fighting. To avoid sparks generated by the formation of welding and cutting scalding incidents and fire incidents, it is necessary to set up high-altitude Welding sparks fight then, using rockwool fire-retardant materials inscribed spark fighting then melt beads, bead avoid splashing out again energize plate .

Fourth, the construction of steel structures means other security approaches Analysis and Research

Strict implementation of the steel unit construction safety management systems and safety procedures, standards, criteria, and do the security approach, severely, "Sambo, four" protection. Stricter enforcement of the rules of safe use of electricity. Working at Height Safety erection of scaffolding, safety barriers and safety nets for protection, the staff necessary to wear a seat belt. Lifting steel unit construction work area should be located cordon, for obvious symbol, and let someone serve. In addition to the safety rope hanging on steel beams, steel columns outside the limb protection should not kept pace with the limb in the floor, the hole set cordon of red and white, and set up warning symbol in the limb at the floor (height work it is necessary to hang your seat belt or safety slogans, etc.). Hoisting prohibit non-construction personnel into or through the lifting area. Trial before the formal lifting cranes, lifting equipment inspection work, ropes, anchor points. After confirmation, before the official lifting. Smooth lifting action, when more than one hoist work together, starting and stopping concerted action to avoid vibration and swinging the workpiece. Time to find a place after being leveled, the workpiece can not unlock fixed before hoisting rigging. Finds it necessary to suspend the lifting process, it is necessary to take timely approach to security, and enhance on-site surveillance, troubleshooting as soon as possible, so that the workpiece can not be a long time in a suspended state. Participate steel construction lifting equipment necessary staff remained at their posts, obey the command to listen to the unified command, no clear signal of inquiry should immediately prohibit the guesswork operation. Field staff positions necessary to have the necessary knowledge of lifting and learn about the procedures, standards. The main component lifting should be done in the morning, the other lifting work should be carried out during the day, avoid work at night. Night work is necessary to have sufficient reliable lighting. Wind prohibited hoisting four and four above, rain and snow nor hoisting work. When hoisting steel apparatus construction, construction workers below the workpiece can not, force a nearby rope and other dangerous places to stay. No person shall when lifting or hoisting equipment lifting of the workpiece, along with special circumstances when it is necessary to lift, it is necessary to adopt reliable approach to security and approved by the relevant responsible person. Member hoisting should fitters, electricians and other maintenance as lifting machinery equipment, should stop work to ensure that power is removed. All steel construction means construction workers it is necessary to wear helmets, high-altitude work necessary to have seat belts. Ban drink steel unit construction work and production whim, ban forced illegal operation.

V. Conclusion

As the steel project has the full in the construction process, the whole process around the clock in a highly dangerous state hole, limb, like high places; professional construction and project management staff are at a high concentration of interchange work environment ; the whole engineering components and construction equipment, materials and other security features specific facilities information required lifting, lifting, etc., to their construction safety management has brought difficult. Therefore, the strengthening of steel construction safety management is particularly important. Hainan Steel
