E. Steel scaffolding manufacturer: the length of the vertical and horizontal horizontal poles in the large angle and vertical facade must be strictly controlled within 10-20 cm, the length is the same, random erection is prohibited, and the length of the extension frame is uneven and uneven. phenomenon.
F. Scissor support: The outer elevation of the scissors support is set continuously. The oblique angles of the diagonal rods of the same elevation should be consistent, so that the length of the overlap is the same, and the vertical level of the edge and the top of the vertical pole is exposed. The length of the rod is uniform.
G. Wall parts: Strictly set up in two steps and three spans, painted with yellow paint and sprayed with the warning word “No removal” H. Scaffolding erection specifications: a skirting board must be installed every two steps of the frame body, and the color code lines should be in the same direction The docking method is smooth and straight as a whole. It is strictly prohibited to use inkjet cloth settings.
I. The size of the scaffold should be matched with the width of the frame to avoid the phenomenon that the bamboo scaffold is exposed (especially at the corners). The scaffold piece should be bound firmly with 18# lead wire in double-strand parallel connection at 4 corners, and the junction is flat and without probe board.
J. After the scaffolding is erected, the inspection and acceptance shall be organized and the acceptance procedures shall be handled. The acceptance part shall be stated in the acceptance form, and the content shall be quantified, and the acceptance personnel shall perform the acceptance signature procedures. If the acceptance fails, the acceptance shall be reorganized after the rectification is completed. It can be used only after passing the acceptance and listing the qualified license.
H. The outer scaffolding steel pipes must be treated with anti-rust, and one anti-rust paint and two yellow top paints should be applied after rust removal. The first step of the scaffolding, the scaffolding and the steel pipes used for safety protection are painted in yellow and black colors with a spacing of 400 mm. High-quality paint should be used. Scaffold erection specifications: the erection height of the external erection requires floor-standing steel pipe scaffolds with a height of 50m and above, cantilevered scaffolds with a height of 20m and above, and attachment-type integral and piece-by-piece hoisting scaffolding projects with a height of 150m and above. The construction unit organizes an expert demonstration meeting. Where general construction contracting is implemented, the general construction contractor shall organize an expert demonstration meeting.
Steel pipe scaffolding manufacturers: requirements for the bottom of the floor stand
1. The scaffolding foundation is flat and compacted, the concrete is hardened, and the floor pole is placed vertically on the metal base.
2. A drainage ditch with a cross-section of not less than 200mmx200mm should be set on the outside of the pole foundation, and the distance between the inside of the drainage ditch and the pole should not be less than 500mm, and concrete should be hardened within a width of 800mm outside.
3. Floor-standing scaffolding must be equipped with vertical and horizontal sweeping poles. Longitudinal sweeping rods should be fixed on a vertical pole not more than 200mm away from the top of the base with right-angle fasteners, and horizontal sweeping rods should also be fixed on the vertical pole immediately below the vertical sweeping pole with right-angle fasteners.
