Different types of engineering construction generally choose different uses of scaffolding and formwork support. At present, cupboard scaffolding is mostly used in bridge support frames, and landing scaffolding is also used in the construction of door-type scaffolding main structure. The longitudinal distance of steel pipe fastener scaffold column is usually 1.2~1.8m, and the transverse distance is usually 0.9~1.5m. Zippered steel pipe scaffold is generally composed of steel pipe rod, zipper, base, hand plate, safety net, etc. Then, let's learn about the erection method and steps of steel pipe fastener scaffold!

1, steel pipe fastener scaffolding pole distance is generally not more than 2.0m, pole lateral distance is not more than 1.5m, clapboard three steps more than three steps, scaffolding bottom is paved with a fixed scaffolding board, working layer is paved with scaffolding board, counting down from the working layer, every 12m scaffolding board

2, steel pipe fastener scaffold rod joint length in addition to the top level of the steps, the rest of the layers of the step joints with butt fasteners. Do not install the joints of the two adjacent valve stems in the same spacing. In addition, in synchronization, the offset distance of two joints separating one shaft rod in the height direction should not be less than 500mm: 1/3 of the distance from the center of each joint to the main node. When the upper pedal pull rod adopts overlapping length, the overlapping length should be more than 1000mm, and it should be fixed with more than 2 rotating fasteners. The distance from the edge of the end fastener cover to the rod end should be more than 10mm.

3. The steel pipe fastener scaffold node is provided with horizontal horizontal bar. Fasten with right-angle zipper, it is strictly forbidden to disassemble. The distance between the centers of two right angle fasteners of the main node should be less than 150mm. On the double-row scaffold, the cantilever length of the horizontal bar on the wall edge should not exceed 500mm.

4. The steel pipe fastener scaffold is provided with longitudinal and transverse cleaning rods. The longitudinal and transverse cleaning bars are fixed on the vertical bar 200mm below the basal epithelium with right angle fasteners. When the support foundation is not on the same horizontal plane, extend the longitudinal cleaning rod at the height to the lower part by two to fix the support, and the height difference should be less than 1m. The distance from the valve stem axis on the slope to the slope is more than 500mm

5. Double-row fastener type steel pipe scaffold with a degree of more than 24m shall be reliably connected with the building by rigid wall members. For single and double-row scaffolds with a height of less than 24m, rigid wall connection members can be used to reliably connect with the building, or supports and supports can be used in combination with the wall connection. It is strictly forbidden to use soft partitions that only tighten the tendons.

6, steel pipe fastener scaffolding glyph, open-shaped double-row steel pipe fastener scaffolding at both ends of the horizontal diagonal brace. For closed scaffolds with a height of 24m or more, in addition to setting horizontal diagonal braces at the corners, every 6 are also set in the middle. The diagonal brace is in the same internode and is serrated and continuous from bottom to top.
