With the emergence of numerous modern large-scale building systems in my country, the traditional coupler-type steel pipe scaffolding can no longer meet the needs of construction development. Developing and promoting new types of scaffolding is therefore urgent. Practice has proven that using new scaffolding not only ensures safe and reliable construction and fast assembly and dismantling, but also reduces steel consumption by 33%, increases assembly and dismantling efficiency by more than double, significantly reduces construction costs, and creates a civilized and tidy construction site.
The scaffolding erection process is as follows: Site leveling and compaction → Concrete foundation pouring → Positioning and setting continuous upright base plates → Laying longitudinal ground bracing → Erecting uprights → Connecting longitudinal ground bracing to uprights → Installing transverse ground bracing → Installing longitudinal horizontal bracing → Installing transverse horizontal bracing → Installing scissor bracing → Installing wall ties → Tying → Laying scaffold boards and toe boards on the working layer. According to structural requirements, measure the distance between the inner and outer uprights and the wall at the four corners of the building, and mark them. Use a steel tape measure to mark the upright positions and mark them with small bamboo strips. The base plate should be accurately placed on the positioning line, and it must be laid flat and not suspended. During the erection of the first layer of scaffolding, a diagonal brace should be installed within each frame grid around the perimeter, with additional braces in both directions at corners. These braces can only be removed after the wall ties connecting the scaffolding to the main structure are reliably secured. When the working level of the scaffolding is two steps higher than the wall ties, temporary stabilization measures should be taken, and these measures can only be removed after the wall ties are fully erected. For double-row scaffolding, the inner row of uprights should be erected first, followed by the outer row. For each row of uprights, the two ends should be erected first, then the middle one, aligning them before erecting the remaining uprights in the middle section. The line connecting the inner and outer rows of uprights in a double-row scaffolding should be perpendicular to the wall surface. When extending uprights, the outer row should be erected first, followed by the inner row.
The dismantling procedure for scaffolding should follow the principle of top-down, erecting first and then dismantling later. The general dismantling sequence is: safety net → railings → footboards → scissor braces → horizontal bars → vertical bars → uprights. Do not dismantle scaffolding by facade or simultaneously at two different levels. Ensure each step and each pole is cleared completely. When dismantling uprights, hold the pole before releasing the last two fasteners. When dismantling longitudinal horizontal bars, diagonal braces, and scissor braces, first remove the middle fasteners, then support the middle section before releasing the end fasteners. All wall ties must be lowered simultaneously with the scaffolding dismantling; it is strictly forbidden to remove wall ties for an entire floor or several floors before dismantling the scaffolding. The height difference between dismantling sections should not exceed two steps. If the height difference exceeds two steps, additional wall ties should be added for reinforcement. Ensure the stability of the scaffolding is not compromised after dismantling. Before removing wall ties, temporary supports should be added to prevent deformation and instability. When the scaffolding is dismantled to the height of the last long steel pipe at the bottom (approximately 6m), temporary outriggers should be erected at appropriate locations for reinforcement before removing the wall ties.
