Description

A cantilever system

technical field

The utility model belongs to the technical field of building construction, in particular to a cantilever frame system.

Background technique

During the construction of the construction project, in order to set up scaffolding on the outside of the building, a large number of I-beams need to be set up on the outer wall as the erection support. However, there are many problems in the cantilever frame system with I-beam as the main component. When most of the I-beam is installed on the exterior wall of the building, the I-beam penetrates the exterior wall, the interior part of the I-beam is fixed on the floor, and the protruding part is used as the support of the scaffolding, which not only causes the exterior of the building to be damaged. The destruction of the wall caused a safety hazard, and a lot of steel was wasted. The dismantling of I-beams is often destructive and cannot be fully recycled. The I-beam is generally used in conjunction with the pull-up rod. The pull-up rod is used to provide the I-beam with rear and upper tension. If the pull-up rod fails, there will be no other auxiliary support force system, and the upper end of the pull-up rod will also have a support for the wall. Larger pull-out component; due to the existence of scaffolding, the upper rod will be fixed on one side of the I-beam, not the middle of the I-beam, so that the pulling force will have a torsion on the I-beam, and the I-beam will have a torsion force. The unbalanced force on the steel makes the entire suspension frame system unstable and reliable. The anti-rust method of the cantilever system is generally spraying paint. If the paint falls off, the anti-rust effect will not be achieved, and the anti-rust treatment cannot be carried out immediately at the construction site, resulting in potential safety hazards. When installing the scaffolding, there is only one I-beam as the support point, which causes the scaffolding to shake to a certain extent and poses a safety hazard. The anti-seismic ability and anti-lightning ability of the existing suspension frame system are also very insufficient.
