Guangzhou Steel teach you: Steel Construction Safety Control handle Exploration
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 though complex, but as long as we can for the main part of the construction process to strengthen the control and view, so fine, standardization handle, I believe we will be able to ensure the smooth construction of production, orderly and safe conduct . Guangzhou Steel
First, limb, hole, high work protection questions Analysis and Research
1, the pressure plate sequentially laying, reduce 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 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 fall lower personnel role. Guangzhou Steel
3, the height of the protective measures work: First Parachute. To prevent falls, the operator during the height of work, it is necessary to use seat belts. Since the steel construction at a large range of activities, seat belt use is generally very 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 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, we use self-locking device fall solve steel ladder without maintenance questions. 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 prevent 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, erected at intervals of not less than 1.2m 3m high 70mm × 70mm × 7mm used to support the safety rope, and the use of baskets 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, 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 platforms. When the steel beams and support equipment, 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, at a distance of 1.2m at the top section of the steel column capitals erected platform. Site construction schedule based on the number of platforms to determine and ensure the normal turnover, does not affect the lifting work. Setting means operating platform for welders build a good working environment, to ensure the safe operation of the welder. The platform disassembly convenient, safe and reliable, to steel columns docking device, proofreading, weld appearance processing, ultrasonic testing and other production processes provides a safety guarantee.
Second, the material lifting, hoisting questions Analysis and Research
1, means the use of tools such as a torque wrench, crowbar, grinder, etc. should be used to maintain security rope to prevent 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 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 stop the construction and to the relevant personnel.
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 prevent 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 means, to prevent 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 prevent the welding sparks produced by cutting and fire incidents caused by scalding incidents, it is necessary to set up high-altitude Welding sparks fight then, using rockwool fire-retardant material inscribed spark fighting then melt beads, bead prevent splashing out again energize plate .
Fourth, the steel unit construction approach to security analysis and other research
Strict implementation of safety devices to handle system of steel construction and safety procedures, standards, criteria, and do the security approach, strict "Sambo, four" protection. Strict implementation of 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 slogans, 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. Recognition is correct, before the official lifting. Smooth lifting action, when more than one hoist work together, start and stop the action to be coordinated together, preventing 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 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, to not immediately clear signal should be asked to prohibit 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 to prevent 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 personnel shall not below the workpiece, the force rope with neighboring and other dangerous place 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 the consent of the 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 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.
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 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 safety features of the equipment and materials 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. Guangzhou Steel
