Basic requirements for the installation of pipe scaffolding

Basic requirements for the installation of pipe scaffolding
The installation sequence of the fastener type steel pipe scaffold is as follows: placing the cantilever components → placing the sweeping rods → erecting the vertical rods one by one and then fastening them with the sweeping rods → installing the sweeping small horizontal rods and fastening them with the vertical rods or sweeping rods → installing the large horizontal rods and fastening them with each vertical rod → installing the small horizontal rods → installing the second large horizontal rods → installing the second small horizontal rods → installing the third and fourth large horizontal rods and small horizontal rods → connecting the wall rods → connecting the vertical rods → adding scissor braces → laying the scaffold board. A dense mesh safety net is hung on the side of the outer upright pole of the scaffold for sealing, and a template or net is planned to be used for sealing between the inner upright pole of the scaffold and the building hand in the construction layer.
4、 The construction requirements for technical points must use qualified materials, and fasteners with deformation and non conformance shall not be used. During the installation of the external tripod, it is necessary to strictly follow the specified construction plan and dimensions, and timely tie it with the structure or use temporary support to ensure the safety of the installation process.
Wall connecting wire must be installed according to the regulations. The installation progress of the scaffold should be followed up in a timely manner to ensure the installation of safety measures such as safety nets. The outer side of the scaffold is fully enclosed with a flame-retardant safety net; The fence is set on the inner side of the outer upright pole, firmly tied to the upright pole and horizontal pole, with a spacing of 30cm between binding points. The safety net is set up in two layers, firmly tied and not missed. Protective railings must be installed on the operation layer of laying scaffold boards, with each guardrail height of 0.9m. Cross bracing must be continuously installed throughout the entire length and height of the outer facade. The angle between the diagonal brace and the ground is between 45 and 60 degrees, and the number of vertical poles crossed by each set of diagonal braces shall not be less than 5. The width of each diagonal brace should not be less than 4 spans and should not be less than 6m. The diagonal bridging rod should be connected to the upright rod, and the lower end of the bottom diagonal rod should be fixed and strictly prohibited from being suspended. The connection of the diagonal braces of the diagonal braces adopts overlapping, and the overlapping length should not be less than 1.0m. Three rotating fasteners are set. During the installation of the external scaffold, both the inner and outer rows of upright poles should be vertical, especially without tilting outward. During the installation process, the verticality and horizontal deviation of the poles should be corrected at any time; Avoid excessive cumulative deviation. When erecting, the joints must be staggered by 50% in the vertical and horizontal directions. All upright poles must be on the ground and suspended upright poles cannot be added to the horizontal pole. When setting up the section upright pole, steel pipes with varying lengths should be selected to ensure that the joint positions of the pole are staggered; The installation of the small crossbar should be perpendicular to the large crossbar, and both ends of the small crossbar should extend more than 10cm outside the large crossbar. The docking fastener connecting the large crossbar should have the opening facing towards the inner side of the frame, with the bolt facing upwards. The cross shaped fastener should not have the opening facing downwards, and the bolt should be moderately tightened. Before the scaffolding is erected, the technical leader of the construction site shall provide written technical disclosure to the professional team leader section by section according to the scaffolding erection and dismantling plan, and complete the disclosure and signature procedures. Each team leader shall hold one copy and supervise each other. The professional team leader shall conduct pre shift technical disclosure to the operators, and keep records of the disclosure. According to the requirements for various materials used in scaffolding, all materials used must be inspected and accepted before they can be used on site. After entering the site, they must be sorted and stacked neatly, and labeled as ready for use. The operators who erect and dismantle scaffolding must have received training and certification from the labor department, and hold a certificate to work. Foundation of Scaffolding Scaffolding
