Anonymous users2024-02-06High formwork support refers to the formwork support operation when the formwork height is greater than or equal to 8m.
The Ministry of Housing and Urban-Rural Development's Jianzhi [2009] No. 87 document "Measures for the Safety Management of Dangerous Sub-project Projects" stipulates:
1. Concrete formwork support project in the sub-project with greater risk: erection height of 5m and above; erection span of 10m and above; The total construction load is 10kn m and above; Concentrated line load of 15kn m and above; The height is greater than the width of the supporting horizontal projection and is relatively independent and has no contact components.
2. Concrete formwork support project in the sub-project with greater risk of exceeding a certain scale: erection height of 8m and above; The erection span is 18m and above, and the total construction load is 15kn m and above; Concentrated line loads of 20 kN m and more.

Anonymous users2024-02-05Let me explain to you, the high formwork happens to be the one I have more contact with in my work.
1. The Ministry of Housing and Urban-Rural Development's Jianzhi [2009] No. 87 document, the notice of the "Measures for the Safety Management of Dangerous Sub-project Projects" states: erection height of 5m and above; erection span of 10m and above; The total construction load is 10kn m2 and above; Concentrated line load of 15kn m and above; The concrete formwork support project with a height greater than the support horizontal projection width and relatively independent without contact components is a sub-project with greater risk.
Erection height 8m and above; erection span of 18m and above; The total construction load is 15kn m2 and above; If the load of the concentrated line is 20kn m or more, it is "a sub-project with a greater risk of exceeding a certain scale". (Note: "This class requires expert argumentation").
2. The Ministry of Housing and Urban-Rural Development's Jianzhi [2009] No. 254 document, "Guidelines for the Supervision and Management of Construction Safety of Tall Formwork Support Systems for Construction Projects" is explained in the notice:
The tall formwork support system refers to the formwork support system of the concrete component formwork at the construction site of the construction project with a support height of more than 8m, or an erection span of more than 18m, or a total construction load of more than 15kN, or a concentrated line load of more than 20KN.
The construction unit shall, in accordance with the current relevant national standards and specifications, be organized by the technical person in charge of the project to prepare a special construction plan for the tall formwork support system in combination with the actual project. And it can be implemented only after expert demonstration.
If you need more information, you can leave an email and I will send you the document to see.
