Steel pipe scaffold of 4 big security hidden danger: 1) Scaffolding is short of a sweeping bar hidden hazards: frame structure is not complete, individual poling instability affect overall stability. According to the relevant standard ( JGJ130 - 6, 2011. 3. Article 2) Requirement: the scaffold must be set longitudinal and transverse rod sweeps the floor. Longitudinal rod sweeps the floor should be right-angle fastener fixed at the bottom from the steel pipe is not more than 200 mm in the vertical pole. Transverse rod sweeps the floor should be right-angle fastener fixed in close to the vertical sweeping bar at the bottom of the pole. 2) Scaffolding poling dangling hidden hazards: easy to cause unstable frame body, the strength is not balanced, collapsed. Relevant standard ( JGJ130 - 2011. 8. 2. Article 3) Requirements: scaffold in use process. Foundation should be without water, the base should be no loose, stud should have no dangling. 3) Longitudinal rod, poling butt joint with across the hidden trouble in synchronous or harm: cause partial uneven scaffolding, affect stability. Relevant standard ( JGJ130 - 6, 2011. 3. Article 6) Requirement: two adjacent longitudinal rod joint should not be set within the synchronization or with cross; Out of sync or different across two adjacent joint in horizontal direction staggered distance not less than 500 mm; The joint center recently to the master node distance should not be greater than 1/3 of the longitudinal spacing ( JGJ130 - 6, 2011. 2. Article 1) ; Two adjacent stud connectors should not set up within the synchronization, synchronization across a vertical rod inside the two adjacent joints in the height direction, staggered distance should be not less than 500 mm; The joint center recently to the master node distance should not be greater than 1/3 of the interval. 4) Even the wall set-up non-standard pieces of hidden hazards: reduce scaffolding ability to resist overturning. Relevant standard ( JGJ130 - 6, 2011. Article 4) Requirement: should be close to the master node layout, deviating from the master node distance should not be greater than 300 mm; We should start with the first step in the bottom longitudinal bar decorate; Even the wall should be horizontally set, when cannot level set, should be inclined to connect one end to the scaffolding; The ends of the open mouth of scaffolding must set the wall, even the wall of a vertical spacing should not be greater than the height of the building, and should not be greater than 4 m; 24 meters high above the double row of scaffolding, should adopt rigid even wall pieces connected to the building; Even the wall three steps can usually be arranged three across a distance, two step three spans, etc.
