Building is important, cantilevered scaffolding specification

A building was built at the beginning of the need to hit the foundation, and then slowly upward extension, as we all know, the building is higher and higher, revealing that built so high, those construction workers need a fulcrum, so that they can be constructed in the high air, ordinary one or two floors, you can use the sturdy bamboo, but in more than 10 floors of the building, and this high-rise building structure and complexity, the construction workers in order to their own safety! As well as this floor can be successfully built on the cantilevered scaffolding, the following, I come to you to say a little cantilevered scaffolding tower setup specifications.

Suspended scaffolding norms

One, the construction program

1, suspended scaffolding must be prepared for the special construction program. Program should have design calculations (including the overall stability of the frame, supporting rod force calculation), targeted, more specific erection and dismantling of the program and safety measures, and draw the plane, elevation drawings, as well as different node details.

2, special construction program including design calculations must be approved by the enterprise technical personnel sign and seal before construction.

Two, overhanging beams and frame stabilization

1, picket outside the picket beam or overhanging frame should be actively used steel or fixed truss.

2, the overhanging steel section or overhanging frame is fixed with the building structure through pre-buried, and the installation meets the design requirements.

3, pick frame uprights and overhanging steel connection must be fixed to prevent slippage.

4, the frame and the building structure for rigid tie, according to the horizontal direction is less than 7M, vertical direction is equal to the height of a tie, the edge of the frame and the corner of the 1M must be set within the tie.

Three, scaffolding board

The pick frame layer by layer full of scaffolding piece, scaffolding piece shall be not less than 18 # lead wire double strand parallel binding not less than 4 points, requires firm, smooth intersection, no probe plate, no gap, scaffolding piece should be guaranteed intact, broken in time to replace.

Four, load? Load

Construction load evenly stacked, and does not exceed 3.0KN/m2. construction waste or unused materials must be removed in a timely manner.

Fifth, delivery and acceptance

1, picket must be erected in accordance with the special construction program and design requirements. The actual erection and the program is different, must be approved by the original program approval department agreed to do a good job in a timely manner to change the program.

2, the pick frame must be set up before the demolition of a targeted safety technology briefing, each take a section of the pick frame need to be briefed once, both sides of the briefing to fulfill the signature procedure.

3, each section of the picket erected by the company organization acceptance, the content of the good, qualified after hanging the qualified card can be put into use. Acceptance of the acceptance of personnel must sign the acceptance sheet, the information on file.

Sixth, rod spacing

The step distance of the picket frame shall not be greater than 1.8M, the spacing of transverse poles shall not be greater than 1M, and the spacing of longitudinal poles shall not be greater than 1.5M.

Seventh, the frame protection

1, the picket frame outside must be certified by the competent authority in charge of the construction of a qualified mesh safety net closed enclosure, the safety net with no less than 18# lead wire hanging tightly. And the safety net should be hung on the inside of the picket frame pole, not the net around the outside of each pole.

2, picket and building spacing greater than 20cm, laying station people piece. In addition to the picket outside, construction layer set 1.2M high protective railing and 18cm high skirting bar, picket inside the encounter edge (such as large openings windows, doorways, etc.), should also be corresponding protection.

Eight, layer protection

The picket work layer and the ground floor should be qualified safety net or take other measures for segmented closed protection.

Nine, scaffolding materials

1, steel pipe scaffolding should be used 48mm outer diameter, wall thickness of 3.5mm A3 steel pipe, the surface is flat and smooth, no corrosion, cracks, delamination, indentation, scratches and hard bending, the new steel pipe has a certificate of conformity. Before erecting the shelf should be maintained, rust removal and uniform coloring, the color should strive for a beautiful environment.

2, steel pipe scaffolding erection of fasteners should meet the requirements of the Ministry of Construction "steel pipe scaffolding fasteners standard", fasteners production license, specifications and steel pipe matching, malleable cast iron, there shall be no cracks, pores, shrinkage of loose, sand and other forging defects, and the pasting surface should be flat, the movable parts of the flexibility of the clamping of the steel pipe when the opening of the minimum distance is not less than 5mm.

3, the section of the steel should be Adopt A3 channel steel or I-beam.

We all know that in the construction site, the most important thing is to protect their own life safety, especially in the construction of high altitude, in addition to wearing a helmet, but also need to fasten the seat belt. After all, life is only once. As mentioned above, the tower of suspended scaffolding set up specifications, but also need to understand, especially the high altitude to do the work of the personnel, to know, this is related to human life and whether this project can be successfully completed.
