Guangzhou Steel News: Steel Construction Safety Control handle inquiry
Followed by the development of society, from the steel works is increasingly being recognized economic, practical, seismic, in use, etc., followed with an increase in steel works, steel in construction, production safety questions more outstanding. Steel Construction site safety handle though complicated, but as long as we can to strengthen the control and inspection for the main part of the construction process, so fine, standardized handling, I believe we will be able to ensure the smooth construction of production, orderly and safe conduct .
First, the question of protection analysis and research limb, hole, high job
1, in order to lay the pressure plate, reducing limb, the onset of the hole 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, The attack also eliminates the need for hole secure channel (in the main beam and pillars of the seam welding, weld appearance processing, ultrasonic testing, several processes up paint job, only in the middle of each of the axes laid together by two scaffold boards makes up the secure channel) laying process. Before laying operations should be laid beforehand hanging over the bottom layer of the pressure plate level safety net, rubato, the adjustment should wear seatbelts, Staking should promptly adjust the pressure plate riveted good good, requiring plank and riveting synchronized springboard shall not leak or riveting riveting, riveting and prevent leakage episodes apron phenomenon.
2, limb, hole protection. Of the elevator shaft on the floor or ground plane, tube wells and the surrounding floor and sides of the hole grew to 1.5m surrounding scaffolding pipe erection height of 1.2m protective railings, entrance Hangings 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 Hangings retardant safety net level (ground floor flat on the ground covered with fire-retardant medium dense mesh safety net). Hole, limb protection to ensure the safety of operating personnel, within the hole to prevent the upper level of the network played a material role of junior officers hurt falling. Guangzhou Steel
3, high job protection measures: First Parachute. To prevent falling height, the operator during the height job, 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 a speed difference from the controller (also known as anti-dropping speed difference or anti-dropping device or buffer) belts. 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 steel ladder, use self-locking device Dropped solve unprotected steel ladder doubt. Self-locking device use should be careful not to hold against; when people climbing, 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 accidents. 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 of 70mm × 70mm × 7mm used to support the safety rope, and the choice of basket bolt tensioning the safety rope, safety rope to prevent excessive 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, do with a 14-round stepladder, ladder width should not be less than 40cm, it is necessary to connect with the steel columns solid, stable, can not shake. Fourth, operating platforms. When the steel beams and support devices, the main girder parts hanging rope security personnel will guard the seat belt hanging rope walking. Steel columns segmenting means. Docking, when the bolt, in order to ensure safe operation of the workers, in the first paragraph of the steel columns from 1.2m at the top of the column erected platform. Site construction schedule based on the number of platforms to determine and ensure the normal turnover, does not affect the lifting operations. Setting means operating platform for welders to create a good working environment, to ensure the safe operation of the welder. The platform disassembly convenient, safe and reliable, to steel columns docking device, calibration, weld appearance processing, ultrasonic testing and other processes to provide a safe production security.
Second, the material lifting, hoisting questions Analysis and Research
1, means the use of things 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, applied to all jobs in industry, perhaps falling objects should be removed or to be fixed.
3, in the high altitude cutting gas cutting or welding, should take measures to prevent cut metal, bead or sparks falling wounding.
4, in the process of lifting and means, first check the rigging, wire rope, hook is solid, you want to choose a suitable hanging points before lifting, if found unsafe should immediately suspend construction danger to the relevant personnel.
Third, Hot Work Analysis and Research
1, according to the requirements of the two groups with flare when effective fire extinguisher, let someone see the fire, then use spark bucket underneath.
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 necessary to regulate placed above the cylinders set quarantine measures to prevent the ignition of the gas cylinder when the cross-operation. It is necessary to have anti-tempering equipment, electrical welder strictly enforce safety rules when using acetylene bottles.
4, welding operations with Cradle 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 provide a safe production security.
5, then the use of spark fighting. In order to prevent accidents and fires caused by scalding attack sparks of welding and cutting, it is necessary to set up high-altitude welding sparks fight then, using rockwool fire-retardant materials inscribed spark fighting then melt beads, bead prevent splashing out again energize plate .
Fourth, the construction of steel structures means that other safety measures Analysis and Research
Strict implementation of safety devices handle steel construction systems and safety procedures, standards, norms, and do all the security measures to crack "Sambo, four" protection. Strict implementation of the provisions of the safe use of electricity. Erection of scaffolding aerial work safety, safety fence and safety nets for protection, workers necessary to wear seat belts. Steel construction lifting equipment work area should be set up alert line, as a clear sign, and let someone serve. In addition to the safety rope hanging on steel beams, steel columns outside, in limb protection in the floor when not kept pace with the limb, the hole to set the alert line of red and white, and set up warning signs in the limb at the floor (height operation it is necessary to hang up the seat belt or safety slogans, etc.). Non-construction personnel hoisting operation is prohibited into or through lifting area. Trial before the formal lifting cranes, lifting equipment inspection job situation, ropes, anchor points. After confirmation, before the official lifting. Smooth lifting action, when more than one hoist operation together, start aborted concerted action to prevent the workpiece vibration and swing. After leveling the time to find a positive place, the work 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 guard, troubleshooting as soon as possible, so that the workpiece can not be a long time in a suspended state. Participate steel apparatus construction hoisting personnel necessary to stick to 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 and codes. The main component lifting should be done in the morning, the other lifting operations should be carried out during the day, at night to prevent the job. Night work is necessary to have adequate and reliable lighting. Wind prohibited in four and four more were lifting, rain and snow can not be carried out lifting operations. 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 safety measures and approved by the relevant responsible person. Member hoisting should fitters, electricians and other lifting equipment as protection equipment, cut off the power to suspend operations should ensure. All steel construction means construction workers necessary to wear safety helmets, aerial work necessary to have seat belts. Do not drink and steel industry means jobs and production facilities whim, forced prohibited illegal operation. Guangzhou Steel
V. Conclusion
As the steel project has the full in the construction process, the whole process around the clock in a highly dangerous state of the hole, limb, like height operation; 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 bring it difficult to handle the construction safety. Therefore, strengthening the construction of steel safety handle is particularly important.
