First, the main components of cantilever scaffolding
High-strength bolts: an important factor affecting structural safety, mainly bearing tensile stress.
Cantilever I-beam: 16# or 18# I-beam is used as the main component, and the material is Q235.
Adjustable pull rod: usually made of 20 or 18 Q235 galvanized round steel, composed of positive screw rod, reverse screw rod, closed adjustable flower basket, and thread protection sleeve.
Lower support rod: generally composed of steel pipe, adjustment sleeve, embedded ring, lower support pull ring, latch, etc.
New wall connection parts: bolt connection, no internal space is occupied, and the risk of leakage is reduced.
Second, the process flow of cantilever scaffolding
Reserve embedded: reserve embedded parts to ensure sufficient preparation before installation.
Cantilever installation: install cantilever beams to ensure safety and stability during installation.
Cantilever acceptance: accept the installation quality of cantilever beams to ensure that they meet the design requirements.
Frame erection: Frame erection is carried out according to the design drawings to ensure the safety of the structure.
Third, precautions before, during and after the installation of cantilever scaffolding
Before installation: formulate a detailed construction plan, conduct technical briefing, and ensure that the construction personnel understand the operation process.
During installation: strengthen inspection and maintenance to ensure that there are no safety problems during the installation process.
After installation: conduct acceptance to ensure that the quality of frame erection meets the requirements.
Fourth, control nodes of cantilever scaffolding
Reserve and embed: ensure that the position and size of embedded parts are accurate.
Cantilever installation: strengthen monitoring during installation to ensure the installation quality of cantilever beams.
Cantilever acceptance: strictly follow the design drawings during acceptance to ensure compliance with the specifications.
Frame erection: strengthen inspection during erection to ensure that the structure is safe and stable.
Fifth, comparative analysis of cantilever scaffolding
Compared with the traditional I-beam cantilever frame, the new cantilever scaffolding has a simpler structure, does not occupy the internal space of the building, and is promoted faster.
The new wall connection is connected by bolts, which do not occupy internal space, reduce the risk of leakage, and effectively prevent workers from illegally removing the wall connection.
Sixth, precautions for cantilever scaffolding
High-strength bolts are an important part that affects structural safety and should be inspected and maintained more frequently.
Embedded parts must include a square nut to increase the force-bearing area.
When the embedded anchor fails, a steel gasket must be added in front of the nut when using a through-screw instead.
