How to calculate full house scaffolding? 20

Recently, there have been a lot of people asking about scaffolding, and I made a standard answer to see if it is useful to you (already).

Full house stand calculation method:

1. Determine the above line load (that is, how heavy is the length of each meter, take the maximum value);

2. Determine the bearing capacity of the foundation (the bearing capacity after reinforcement);

3. According to the bearing capacity of the foundation, roughly determine how many vertical pipes are supported per square meter and assign them to specific point loads;

4. Determine how many tons each vertical pipe can withstand (calculate the allowable stress according to the pipe diameter and pipe wall thickness);

5. According to the bearing capacity of the foundation and the tonnage of the vertical pipe, determine the spacing of the vertical pipe; The position of the transverse tie beam can be considered as a dense point;

6. After the vertical rods are arranged, the horizontal rod spacing should be considered. The general spacing should not be greater than meters (the spacing is calculated by the instability of the pressure rod);

7. Attention! The horizontal rod should have a rod near the ground and at the top surface (some people always think that it is not needed here, but it is often easy to lose stability up and down and it is difficult to insecure);

8. Longitudinal diagonal brace configuration, the full bracket diagonal brace should be continuously configured from top to bottom 45°, and the middle cannot be broken (that is, a diagonal brace is from the top to the ground, and the middle side is long); The diagonal brace configuration is generally empirical, but it can also be calculated (using the plane intersection force system, which has been learned in theoretical mechanics);

9. The transverse diagonal brace configuration is the same as the longitudinal one;

10. Loading calculation: it is enough to consider the concrete load for three days, if the concrete is divided into two times, it is not necessary to add all the loads, because the concrete poured in the previous time is generally solidified, it is not a load, which is beneficial to the calculation.

Note! This calculation is carried out with the foundation fully guaranteed, and it is difficult to say if the foundation softens in water during construction.

First of all, it is necessary to determine the height: the following is not calculated, when the basic layer is calculated, more than each more than one layer, insufficient is not calculated.

Secondly, the area is calculated according to the net indoor area within the actual erection range.

Full scaffolding additional layer = [Indoor clear height

1. If the indoor height exceeds the plastering greenhouse or decorative surface ceiling, the scaffolding should be calculated.

2. The full scaffold is calculated by the horizontal area, and the area is calculated according to the horizontal projection area of the ceiling constructed by the full scaffolding, without deducting the area occupied by the stacks, columns, and chimneys attached to the wall;

3. The height of the full scaffold is calculated from the indoor floor to the bottom of the greenhouse;

4. The basic layer of the full scaffold is prepared within 8m, and when the height of the increased layer exceeds 1m, it can be calculated according to the height of an additional layer.

Use full house scaffolding:Decorative scaffolding is no longer calculated separately for interior wall decoration below meters, and masonry scaffolding for interior walls is still calculated according to the provisions of internal scaffolding. The use of full scaffolding depends on its height, and if the net height of the ceiling is below the ceiling, no matter what kind of decoration technology is used in the ceiling, the decorative scaffolding is not counted.

When the net height of the shed is between to, the decorative scaffolding of the ceiling is calculated according to the quota of the full scaffolding layer, and when the net height of the shed is above, the decorative scaffolding of the ceiling should be calculated as the basic layer and the additional layer of two quota items.

Hello answer, I have a general understanding of the question you asked, and I am sorting out the answer, please wait patiently 1. When calculating the scaffolding, you need to calculate its additional layer, which is related to its floor height. First of all, you need to understand how high the floor is, then subtract the meters, take this data and divide it by the meters. If the height of the floor is less than meters, the cost of scaffolding is not calculated.

If the height is between meters and 10 meters, it needs to be calculated according to half of the basic layer sub-purpose of the scaffolding.

2. If it is a ceiling, its net height is below the meter, no matter what kind of decoration process it is, there is no need to calculate the scaffolding. However, if it is between meters and meters, it needs to be calculated according to the quota of the scaffolding layer. If the meter is exceeded, the base layer and the additional layer need to be added together during the calculation.

Calculated according to the horizontal projection area of the actual tower, without deducting the area occupied by the attached wall columns and columns, the basic floor height shall prevail to the above. For the plastering and decoration of the ceiling that exceeds the limit, the basic layer of scaffolding should be calculated.

If the height of the layer is exceeded, an additional layer is calculated for each increase, and the number of layers of the additional layer = (layer height, rounded to the nearest integer.) If the indoor scaffolding is calculated, the interior wall decoration will no longer be counted as the decorative frame, and the erection man-days will only be increased by every 100 vertical projection area of the wall.
