Scaffolding is divided into three types:

    1. There is no actual pattern for the integrated scaffolding. If there is a variety of projects that require scaffolding at the same site during the Jian'an construction, this scaffolding project can be used, and no other scaffold installation projects can occur. During construction, the construction unit can build it as needed. The cost of this project is high.

    2. The external scaffolding is a scaffold for external wall construction. The internal scaffolding is used for the construction of internal walls. However, general civil construction and civil construction cannot apply internal scaffolding. In the construction of the pipeline, it is also in the height of more than 3, 6 meters above the scaffolding project.

    3, in the height is not too high, and less weight bearing place, you can use a single row of scaffolding. General multi-storey building exterior wall construction uses double-row scaffolding. Construction of high-rise buildings, if using scaffolding, must do safety accounting, because high-level scaffolding accidents occur repeatedly.

    Second, gate scaffold construction note:

    1. The deformed rods and unqualified fasteners (cracks, improper sizes, unstable buckles, etc.) of the moving scaffold cannot be used, and are erected in accordance with the specified construction scheme and dimensions.

    2. If there is no finished frame, it is necessary to ensure that the shelf is stable in order to avoid accidents and tighten the fasteners. The erection workers must wear safety belts. Correct the vertical and horizontal deviation of the bar at any time to avoid excessive deviation.

    3. The lightning protection measures of the outer frame adopt the commonly used galvanized pipe grounding scheme. In the construction of thunderstorms, workers are generally not allowed to perform construction work on shelves. Timely and structural pull knots or temporary support to ensure the safety of the erection process.

    Third, the installation requirements for mobile scaffolds and portal scaffolds:

    1, cast-in-situ reinforced concrete wall, according to the length of the wall structure multiplied by the height in square meters, the use of the corresponding height of the double-row scaffold project.

    2. Cast-in-situ reinforced concrete single beam or continuous beam, calculated according to the length of the beam structure multiplied by the height of the outdoor design floor to the top surface of the beam, in square meters, and apply the double-row scaffolding project of the corresponding height, and the associated frame column No more scaffolding calculations.

    3, Independent brick, stone, reinforced concrete column, according to the circumference of column structure plus 3.6m multiplied by the area of the column height; height below 3.6m, apply a single row scaffold scaffolding; 3.6m or more apply the corresponding height Double-row scaffolding quota.
