Hainan Steel News: Steel Construction Safety Control handle Exploration

Foreword
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 questions increasingly The more prominent. Steel Construction site safety handle despite complicated, but as long as we can to strengthen against the major part of the construction process control and visibility, so fine, standardized handling, I believe we will be able to ensure the smooth construction of production, orderly and safe conduct .

First, limb, hole, high protection work analysis and discussion questions
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 central portion of each axis laying 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 prevent leakage phenomenon occurs apron.
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, the hole in the flat screen acts to prevent injuries to the upper material falling lower personnel role.
3, the height of the protective measures work: First Parachute. To prevent height fall, the operator during high places, it is necessary to use seat belts. Since the steel construction activity when a larger range, use an ordinary seat belt is difficult to meet the construction requirements, should be used with the speed difference from the controller (also known as anti-dropping speed difference or buffers or anti-dropping) seat belt. When lifting steel columns and apparatus, in order to ensure that workers removed hoisting rope used in the security situation in the hook by hanging ropes at a height determined according to the site, for hanging seat belt safety catch. When people climb the steel ladder, we use self-locking device Dropped resolve questions unprotected steel ladder. Note the use of self-locking device should not 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 avoid falling 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, erected at intervals of not less than 1.2m 3m high 70mm × 70mm × 7mm for supporting a safety rope, and the choice of basket bolt tensioning safety rope, safety rope to prevent long cause fail-safe. 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, using 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 connect with the steel columns for 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, from the first stage in the erection of the steel column capitals 1.2m operating channels. Number of channels according to the site to determine the construction schedule, to ensure the normal turnover, does not affect the lifting work. Setting means operating channels to build an outstanding welder working environment to ensure safe operation of the welder. The channel dismantling convenient, safe and reliable, to steel columns docking device, calibration, weld appearance processing, ultrasonic testing and other processes to provide a safe production guarantee.
Second, the material lifting, hoisting analysis and discussion questions
1, what means to use, such as a torque wrench, crowbar, grinder, etc. should be used in safety rope to prevent falling. Readily with bolts and gaskets should be placed in bags of stuff.
2, the construction work of all the objects may fall, should be removed or to be fixed.
3, in the high altitude cutting gas cutting or welding, approach should be adopted to prevent the cut metal, bead or sparks falling wounding.
4, in the process of lifting and devices, the first view the rigging, rope, hook is solid, you want to choose a suitable hanging points before lifting, if found unsafe condition should immediately report the officer to suspend construction.
Third, the Hot Job Analysis and Discussion
1, required equipment flare fire extinguisher in the two groups, let someone see the fire, then use the bucket underneath spark.
2, the hand must not touch the oxygen cylinder oil, to prevent the crane or other mechanical oil fell on the oxygen cylinder.
3, oxygen and acetylene bottles necessary to regulate placed above the cylinders set the isolation approach, working to prevent cross-ignition of gas cylinders. If necessary, use of acetylene bottles anti-tempering equipment, electrical welder strictly enforce safety procedures.
4, welders role Basket hang provided on the main beam wing pendant. Welding operator seat belt safety rope hung, to the centering 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 provide a safe production guarantee.

5, then the use of spark fighting. In order to prevent sparks generated by the formation of welding and cutting scalding incidents and fire incidents, it is necessary to set up high-altitude Welding sparks then fight, fight using rockwool inscribed spark of flame retardant material pick bead and prevent splashing out again energize bead plate .
Fourth, the construction of steel structures means other approach to security analysis and discussion
Strict implementation of safety devices to handle system of steel construction and safety procedures, standards, norms, and do the security approach, severely, "Sambo, four" protection. Strictly enforce the provisions of the Security 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, as a clear sign, and let someone responsible. In addition to the safety rope hanging on steel beams, steel columns, the limb should protect not kept pace with the limb in the floor, the hole set cordon of red and white, and set up warning signs in the limb at the floor (height work it is necessary to hang your seat belt or safety posters, banners, etc.). Hoisting prohibit non-construction personnel into or through the lifting area. Trial before the formal lifting crane to see the work of lifting equipment, ropes, anchor points. After confirmation, before the official lifting. Smooth lifting action, when more than one hoist work together, startup aborted 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, the need for timely adoption approach to security, and enhance on-site surveillance, troubleshooting as soon as possible, so that the workpiece can not be a long time in suspension status. Participate steel construction lifting equipment necessary staff remained at their posts, obey the command to listen to the unified command, to not immediately clear signal should be asked to prohibit guesswork operation. Field staff positions necessary to have the necessary knowledge of lifting and learn about the rules, norms. 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 a reliable approach to security and approved by the responsible person. Member hoisting should fitters, electricians responsible for the maintenance lifting machinery equipment, should suspend work to ensure 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 means the construction work and the production of steel whim, ban forced illegal operation. Hainan Steel
V. Conclusion
As the steel project has the full in the construction process, the whole process around the clock in a highly dangerous situation hole, limb, like high places; professional construction workers and engineering staff are at the height of the handle intensive interchange work environment ; the whole engineering components and construction equipment, materials and various security facilities material characteristics required special hoisting, lifting, etc., to the safety of its construction makes it difficult to handle. Therefore, strengthening the construction of steel safety handle is particularly important. Hainan Steel
