Sectional steel tripod and scaffolding system in a cantilevered scaffolding

Abstract

The invention relates to a section steel tripod for a cantilevered scaffold. The section steel tripod comprises a beam, a vertical strut and an inclined strut, wherein the beam, the vertical strut and the inclined strut form a triangular structure; a small vertical strut is arranged between the beam and the inclined strut; a small cross strut is arranged between the vertical strut and the inclined strut; strong-strength bolt preformed holes are formed in the vertical strut; the vertical strut is connected with a structural column or a wall body through the preformed holes by anchor parts to realize the mounting of the section steel tripod; 14# I-steel is adopted for the beam and the vertical strut; 10# I-steel is adopted for the small vertical strut and the small cross strut; the beam is provided with stiffening rib plates; and limiting reinforcement heads are arranged below the beam. For a local core tube part (such as an elevator room position and a staggered floor of steel cantilever beams) without a floor slab, steel beams of an ordinary cantilevered scaffold cannot be normally arranged, and is fixedly arranged on a main body structure through the section steel tripod, and stress on the cantilevered scaffold is transmitted to a structural wall body through anchoring bolts by the tripod, so that the tripod is clear in stress and simple in stress transmission, and can be recycled, the construction safety and operability are ensured, a requirement on a construction period is met, and the efficiency is improved.

Description

technical field [0001] The invention relates to the field of scaffolding, in particular to a cantilevered steel pipe scaffolding system. Background technique [0002] The cantilevered scaffolding project is a highly dangerous sub-project in construction. The unreasonable design or incorrect use of the cantilevered scaffolding will bring serious threats to the lives of construction personnel and bring great harm to the construction of the project. The difficulty will have a bad impact on society. In particular, the construction of the cantilevered steel beams at the corners of the building is very critical. The steel beams at the corners of the building are laid radially in the traditional cantilevered scaffolding. This method is too concentrated, which is not conducive to structural safety and has great potential safety hazards. .
