Anonymous users2024-02-07The limit of the height of the scaffolding erection.
1) Adopt double poles below the elevation of 20m and partial unloading measures above the elevation of 30m.
2) The height of the erection is more than 50m, and all the unloading measures are adopted in sections.
3) Adopt picking, hanging, hanging type or attached lifting scaffolding.
4) Single-row and double-row scaffolding with a height of less than 24m must be provided with a scissor brace at both ends of the outer façade, and should be continuously set from bottom to top; The net distance between the middle scissor supports should not be greater than 15m

Anonymous users2024-02-06The height of scaffolding cannot be generalized, and its height is different depending on the type of use. The details are as follows:
1. If a single row of scaffolding is erected, the height shall not exceed 24 meters;
2. The height of double-row scaffolding shall not exceed 50 meters;
3. Cantilevered scaffolding.
The height of the ride must not exceed 20 meters;
4. The height of the scaffolding of the whole hall shall not exceed 36 meters.
Compared with the general structure, the working conditions of scaffolding have the following characteristics:
1. The variability of the load is large;
2. The fastener connection node is semi-rigid, and the rigidity of the node is related to the quality of the fastener and the installation quality, and there is a large variation in the performance of the joint;
3. There are initial defects in the scaffolding structure and components, such as the initial bending and corrosion of the rods, the erection size error, and the load eccentricity are large;
4. The connection point with the wall has a large variation in the constraints of the scaffolding.

Anonymous users2024-02-051. In the specification of the requirements for the height of scaffolding erection: the height of scaffolding erection requires that the height of single-row scaffolding should not exceed 24m, and the height of double-row scaffolding should not exceed 50m, and the cantilever scaffolding.
The erection height should not exceed 20m, full of scaffolding.
The erection height should not exceed 36m, the erection height of the full support frame should not exceed 30m, 2, when the full support frame is less than 4 spans, it should not exceed the rubber, the erection height of the disc buckle formwork support should not exceed 24m, the structure requirements of the scaffold rod, 1 vertical pole erection requirements are the key components of the scaffold, the main stress rods, and the components responsible for transmitting and bearing the force. The spacing of the poles should be evenly set and should not be greater than the design spacing, otherwise the bearing capacity of the poles will be reduced.
3. The erection height of mobile scaffolding is generally not more than 15 meters to 20 meters, which can be in accordance with the "Safety Technical Specifications for Fastener Steel Pipe Scaffolding in Building Construction", "Safety Technical Specifications for Gantry Steel Pipe Scaffolding in Building Construction", and "Several Regulations on the Prevention of Falling Accidents from Heights in Construction Engineering".

Anonymous users2024-02-04Hello friend, it is a pleasure to serve you, your problem I have seen, according to my understanding, the standard size of scaffolding erection can vary according to the specific country, region or industry barrage standard. Here are some common scaffolding erection standard sizes for reference:1
Crossbar (horizontal bar) length of the bar: usually 2 meters, meters or 3 meters. The crossbar is used to connect the upright pole and support the platform of the scaffolding.
2.Pole (vertical pole) height: usually 2 meters, meters, or 3 meters.
Upright poles are used to support the entire scaffolding structure. 3.Vertical (vertical spacing):
Usually meters or 2 meters. Vertical spacing refers to the vertical spacing between upright poles, also known as vertical spacing or scaffolding spacing. 4.
Rungs (horizontal spacing): usually 2 meters or meters. A rung refers to the horizontal spacing between the crossbars, also known as the lateral spacing or scaffolding length.
It should be noted that these dimensions are for reference only, and the actual scaffolding erection may be affected by various factors, including specific engineering requirements, use environment, safety requirements, etc. Therefore, before the actual erection of scaffolding, it is advisable to carry out detailed planning and design according to relevant local regulations, standards or professional guidelines, and follow the relevant safety operating procedures. Also, if you need to erect scaffolding, it's best to consult a professional scaffolding erection company or a professional who does scaffolding work to get accurate advice and guidance.
Single-row scaffolding is not used too much at present, it has been banned in individual places, Jinan has strictly prohibited the use of single-row scaffolding The maximum height of double-row scaffolding erected in accordance with the regulations is 50m, you need to determine by calculation, the things that need to be calculated in the specification must meet the requirements, especially the bearing capacity of the foundation or the bearing capacity of the floor slab I have seen The highest scaffolding height is more than 70m, which is a secondary transformation project, because the main structure has been completed in the early stage, and the cantilevering is more difficult. Therefore, the use of floor scaffolding at the bottom of 30m using double poles, and in strict accordance with the two-step three-span plus tie point, at the same time in 20m, 40m, 60m to do a good job of unloading measures, one is to use the wire rope cable, the other is to add diagonal bracing steel pipe from the floor slab due to the large time in the past of the project, the above data can not be remembered, but generally in the above personal opinion that the measures are appropriate, the scaffold can be erected to more than 70m, but if it is a new high-rise, It is recommended to use cantilever scaffolding, after all, the maximum erection height is 50m, and the supervision department does not allow you to exceed this height.
1. The backing plate and base should be accurately placed on the positioning line, and the backing plate must be laid smoothly and not suspended. >>>More
No. Floor scaffolding can exceed 36. More than 50 is also fine, but it is often necessary to have a double pole. The management regulations of the sub-project with greater risk, the landing frame exceeds 50 meters, which requires expert demonstration. Steel pipe fastener type scaffolding. >>>More
Reinforcement Train the entire scaffold into one to prevent collapse.
Safety is the first priority. 1. If the erection height of the scaffolding of the exterior wall is between 25 meters and 50 meters, we need to continue to strengthen the overall stability of the scaffolding, such as continuously setting it on its longitudinal plane, and at the same time increasing the frame rate of the transverse scissors. When the wind blows, the construction of scaffolding with a height of more than 40 meters should be structurally strengthened. >>>More
