According to different types of cantilever members, they can be divided into two types: one is 5e48mm × 3.5mm steel pipe, one end is fixed on the floor and the other end extends out.
(2) Internal scaffolding.
The scaffold or structure inside the building is called internal scaffold.
Attached lifting scaffold: the scaffold that is connected to the outside of the building and can be lifted by itself is called additional lifting scaffold.
There are three types of supports.
Shandong scaffold construction qualification agency.
According to the building purpose, it can be divided into masonry structure and decorative frame; According to the location, it can be divided into external scaffold and internal scaffold.
Generally speaking, what is the height of a building and its erection height.
Therefore, we must not be careless in the selection, construction and construction quality of scaffolds.
Shandong scaffold construction qualification agency.
Single row scaffold: it is composed of many single row suspenders and large and small buckles or binding.
If you have any questions or needs for construction scaffolding, you can also contact us directly…
(4) Repair and reinforcement.
(3) Tool support: this building does not come directly from the ground, but is built in the form of cantilever walls or columns.
Construction type of scaffold.
Including: inner scaffold, horse stool and column scaffold.
Steel scaffolds are divided into gusset plate type, turnbuckle type, door type and tool type; According to the arrangement of vertical poles, they can be divided into single row frame, double row frame and top hall frame.
Scaffold shall be set on the cantilever rod, and the height shall not exceed 6 steps; Or make cantilever reinforcement with section steel.
The height of the building shall not exceed grade 20 (total height 20 ~ 30m).
I hope it can help you.
Pintuo qualification contact number: 13688317880 scaffold is an indispensable temporary facility during construction.
(1) Set up safety ladders, ladders or slopes for operators.
(3) When multi-layer operation is carried out at the same time, reliable protective covers shall be installed between the operation layers to prevent falling objects from damaging the bottom workers.
The external scaffold is erected from the ground, so it is also called bottom support.
If the scaffold is not established in time, the project progress will be delayed; The scaffold cannot meet the construction needs, the operation of employees is inconvenient, the quality is difficult to guarantee, and the scaffold erection is not firm and stable, which is easy to cause casualties.
As far as building materials are concerned, there are both traditional bamboo and wood scaffolds and steel pipe scaffolds.
Sort out the contents above.
Due to the development of construction technology, the types of scaffolds are increasing.
The special construction scheme shall include the plan and measures for scaffold demolition, which shall be strictly followed in the demolition process.
It is mainly applicable to foreign decoration projects.
Lifting points are set on the roof and suspended by steel wire rope.
(2) After installation, it shall be accepted and can be used only after passing the acceptance.
Scaffold: it is composed of a plurality of inner and outer rows of vertical bars and large and small cross bars tied or buckled.
Steel door pipe scaffold.
In the process of scaffold installation project, the project will not be completed, but it will directly affect the construction speed, work efficiency, construction quality and workers’ personal safety.
The scaffold installed on the building or the outer surface of the building is called external scaffold.
Use and management of scaffold.
(1) Outer support.
Especially for high-rise scaffolds and full hall scaffolds, multiple inspections and acceptance shall be carried out before use.
Basket scaffold: its basic components are welded into a rectangular frame with 50mm ~ 3mm steel pipes, of which 3 ~ 4 trusses are a group.
Hanging scaffold: it refers to hanging the scaffold on the wall or embedded in the column on the hook, and laying the scaffold board on the scaffold board.
Scaffolds shall be built for masonry wall, concrete pouring, wall plastering, plastering mortar, installation of structural components, etc., so as to facilitate construction and stacking of building materials.
The above are the types and precautions for the handling of Shandong construction scaffold project.
