At present, disc-type scaffolding is very popular in the scaffolding industry. Due to the promotion of macroeconomic policies, the disc-type scaffolding market is in short supply. However, many colleagues who are new to disc-type scaffolding, are not very familiar with the engineering usage of the disc-type scaffolding. Therefore, the editor summarizes some methods to quickly calculate the usage of the disc-type scaffolding, hoping to help you.
1. Building exterior wall frame
According to the conventional construction plan, the height of the double-row frame of the exterior wall is generally not more than 20 meters, and the longitudinal spacing is about 0.9 meters. Each layer of the double-row frame of the exterior wall needs to be laid with steel foot pedals and equipped with safety facilities such as double-layer guardrails, footboards, and diagonal bars to prevent scaffolding overturning accidents. How to calculate the usage area of the disc-type scaffolding? When we understand the area of the building’s exterior wall, we can roughly calculate the required scaffolding usage. For example, assuming that the height of the outer wall is 10 meters and the length is 8 meters, the area of the scaffolding is usually 10 meters by 8 meters, which is about 100 square meters. Based on this area calculation, the required scaffolding consumption is about 27 to 28 tons. It should be noted that in the actual construction process, the length and height of the building’s outer wall may vary, so there will be a certain standard error.
2. Built-in full-height frame
In actual construction, one or more layers of built-in full-height frames are usually set up at specific locations to serve as construction operation platforms. According to conventional standards, the structure of the built-in full-height frame is mainly 1.8 meters by 1.8 meters, and 1 to 2 channels are set at the bottom. Unlike the external wall frame, the measurement unit of the built-in full-height frame is usually calculated in meters. Therefore, when calculating the construction consumption of the scaffolding, you only need to know the cubic number of the erection area to roughly estimate the required scaffolding consumption. Taking a conventional standard as an example, the consumption of a full-height frame is about 23 to 25 kilograms per cubic meter, so the consumption of a full-height frame of 100 square meters is about 23 to 25 tons. Through such an estimate, the amount of the required disc-type scaffolding can be roughly calculated.
3. Formwork frame
The formwork frame is different from the full-height frame and the external wall frame. It does not need to set up upper and lower passages and operating platforms during the construction process. Therefore, when calculating the number of discs of the formwork frame, the feet for building upper and lower passages and operating platforms are usually excluded according to the actual situation on site. According to the conventional standard, it is assumed that the structure of the formwork frame is 900×900 or 1200X1200, and the parameters of 900*1200 are used for calculation. The consumption of the formwork frame is about 17~19 kilograms/cubic meter. By understanding the cubic number of the formwork frame, the consumption of the disc-type scaffolding can be roughly estimated. The above is the calculation method of the disc-type scaffolding in construction. However, in the actual construction process, if you want to accurately calculate the specifications and quantities of various rod accessories, you need to combine the actual construction plan drawings for calculation. Especially when encountering projects with special requirements, the above method may not be very practical and the error is relatively large. However, when understanding the initial needs of Party B in the early stage of the project, the above method of calculating the amount of disc-type scaffolding is still relatively practical.
