Pan-buckle scaffolding is one of the commonly used temporary facilities at construction sites. It refers to a frame that temporarily places construction tools and a small amount of building materials to solve the problem of construction workers working at heights. The equipment consists of a pile base, earthwork, temporary power, construction machinery and tools, three treasures and four ports, edge guards, hoisting machinery, fire protection, etc. It is the focus of construction and is also a common problem, and scaffolding is the cause of safety production accidents. As one of the most frequent places, safety supervision at all levels requires a lot of effort to ensure safety. Disk-type scaffolding is the safest and most beautiful scaffolding.
The width of each scissor brace shall not be less than 4 spans and shall not be less than 6 meters. The angle of inclination between the diagonal and the ground is between 45 and 60 degrees. Double-row scaffolding with a height of 24 meters and above shall be equipped with scissor braces in sequence on the outer facade; single-row and double-row scaffolding with a height of 24m and below shall be installed on the facade. The distance between the outer ends, corners, and centers shall not exceed 15m. Each scaffold shall be Set up with a scissor support from bottom to top.
The cross braces of double-row scaffolding should be placed in the same intersection in a zigzag pattern from the bottom. Double-row scaffolding with a height less than 24m does not need to be provided with cross braces, and closed scaffolds with a height exceeding 24m are provided with cross braces every 6 spans in the middle. Cross braces need to be installed at both ends of the open double-row scaffolding.
Missing does not count. Do not use internal scaffolding, if any. Difference (in horizontal projection); Scaffolding is usually erected when interior walls are laid or walls are painted after plastering; large supported formwork uses scaffolding with closed seats (one around the wall and one in the entire room), It refers to a single scaffolding, and some lower components have no construction area.
But if it exceeds, forget it. If there is scaffolding and base, it must be calculated based on the corresponding base area. If the ceiling decorative scaffolding with a floor height greater than the above is included, there is no need to calculate the ceiling scaffolding. Generally speaking, when building scaffolding, construction workers have relatively high requirements and standards for its accessories.
First, the setting requirements for scaffolding: the setting of scaffolding must comply with the construction progress and should not exceed a group of adjacent walls. After 2 steps, check the step distance, vertical distance, horizontal distance, and verticality of the vertical pole of the scaffolding at each step;
Second, the basic settings must meet the following requirements: the base and tablet are positioned accurately. The circuit board should be a plate with a length of no less than 2 spans and a thickness of no less than 500mm, and channel steel can be used.
Column: The polarization setting must meet the following requirements: it is strictly prohibited to expand the mixed polarization to steel pipes with an outer diameter of 48mm and 51mm and use butt joints between each layer.
The accessories required for scaffolding in construction mainly include the following aspects.
