First, the limb, the hole, protection problems working height analysis and discussion
1, the pressure plate in order to lay, cut limb, the hole generating pressure plate laying steps rubato, adjustment, riveted, laying sequence should start from the side of successive start laying the perimeter, that is to cut the 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 be laid at the bottom of the pressure plate beforehand hanging over one 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 avoid leakage occurs apron appearance.
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 play to avoid falling material injury to the upper junior staff role.
3, protective measures height works: First Parachute. To avoid falling height, the operator during high places, it is necessary to use seat belts. Since the steel construction when a large scope of activities, the selection of the general 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 in a safe state by removing the hoisting rope, 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, use self-locking device Dropped solve the problem of unprotected steel ladder. Use self-locking device should pay attention not hold against; when people climb, self-locking device with construction workers always counterparts. It is necessary to seat belt hanging on the hook safety catch to avoid falling accidents. Second, beams, safety rope hanging on steel columns. After more than two fixed steel columns stability, 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 the safety rope, safety rope to avoid too long cause fail-safe. When workers walking on the beam, with the necessary security safety ropes hanging. Third, the steel ladder setting. Temporarily lifting with the ladder, the choice of 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 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. Site construction schedule based on the number of channels 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 dismantling convenient, safe and reliable, to steel columns docking device, proofreading, weld appearance processing, ultrasonic testing and other processes guarantee the supply of safe production.
Second, the material lifting, hoisting problem analysis and discussion
1, means the use of tools such as a torque wrench, crowbar, grinder, etc. safety rope should be used, to avoid falling. Readily with bolts and gaskets should be placed in the tool bag.
2, the construction work in all possible falling objects should be removed or to be fixed.
3, in the high altitude cutting gas cutting or welding, should take measures to avoid cut metal, bead or sparks falling wounding.
4, in the process of lifting and means, first check 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 stop the construction.
Third, Hot Work Analysis and discussion
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, the hand must not touch the oxygen cylinder oil, to avoid the 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 measures to avoid cross-ignited gas cylinders working. If necessary, the use of acetylene bottle with anti-tempering device, strict implementation of electrical welder safety procedures.
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 production processes provides a safety guarantee.
5, then the use of spark fighting. To avoid scalding accidents and fire sparks produced by welding and cutting, welding and cutting height it is necessary to set up contact spark bucket, use rockwool fire-retardant material inscribed spark fighting then melt beads, bead avoid splashing out again energize plate .
Fourth, the steel unit construction analysis and discussion of other security measures
Strict implementation of the steel unit construction safety management systems and safety procedures, standards, criteria, and do all the security measures, strict, "Sambo, four" protection. Strict implementation 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, 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 slogans, etc.). Hoisting prohibited into or through non-construction personnel 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 the workpiece vibration and swing. 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 safety measures, 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, to not immediately clear signal should ask, non guesswork operation. Field staff positions necessary to have the necessary knowledge of lifting, and familiar with the relevant regulations, 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 in four and more than four hoisting, nor sleet weather hoisting work. When hoisting steel apparatus construction, construction personnel shall not below the workpiece, the force with neighboring ropes 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 safety measures and approved by the relevant person in charge. Member hoisting should fitters, electricians responsible for the maintenance lifting machinery equipment, cut off the power to stop working should be ensured. All steel construction means construction workers necessary to wear helmets, high-altitude work necessary to have seat belts. Do not drink and steel unit construction work and production whim, forced prohibited 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 various security facilities material characteristics required special hoisting, lifting, etc., to their construction safety management difficult. Therefore, the strengthening of steel construction safety management is particularly important. Guangzhou Steel
