Ring lock type double-row outer scaffold cantilever structure and construction method thereof

Abstract

The invention discloses a ring lock type double-row outer scaffold cantilever structure. The ring lock type double-row outer scaffold cantilever structure comprises a scaffold. The scaffold is composed of multiple bodies. Each body comprises a horizontal rod, an inclined rod and four vertical rods, wherein double-groove type longitudinal beams are mounted between two vertical rods and the other two vertical rods, the two double-groove type longitudinal beams are arranged in parallel, an adjustable supporting seat is connected to the double-groove type longitudinal beams, an adjustable supporting seat sleeve is arranged on the adjustable supporting seat, the adjustable supporting seat and the adjustable supporting seat sleeve can relatively move up and down, the adjustable supporting seat comprises a lead screw with an outer thread, a jacking baffle with a groove type opening and an adjustable nut screwed to the lead screw, and the jacking baffle is connected to the bottoms of the double-groove type longitudinal beams. Each adjustable supporting seat sleeve comprises a round steel sleeve, a cushion plate with a round hole and a sleeve limiting plate, wherein the cushion plate and the sleeve limiting plate are welded to the upper end and the lower end of the round steel sleeve. The round steel sleeves sleeve the lead screws, the cushion plates are located below the adjustable nuts, and a double-groove type cantilever steel beam is arranged between the two round steel sleeves. The ring lock type double-row outer scaffold cantilever structure is ingenious in design and convenient to construct.

Description

technical field [0001] The invention relates to the technical field of scaffolding, in particular to a ring-type double-row outer scaffolding cantilever structure and a construction method thereof. Background technique [0002] The traditional method of buckle-type cantilevered scaffolding is usually to disconnect the scaffolding frame at a height of about 20m at intervals, and pre-embed U-shaped steel bars at the front and rear points of the cantilevered floor to fix 4-6m long I-shaped steel cantilevered out of the floor , Lay two longitudinal I-beams on the cantilevered I-beams (reason: the horizontal bar of the buckle scaffolding is a fixed modulus, and the pre-embedded position of the cantilever I-beams is difficult to be accurate, and it is impossible to guarantee that each The cantilevered I-beam is just located at the position of the pole of the buckle-type scaffold), and then a scaffold of the cantilevered section is re-built on the longitudinal I-beam, and the steel...

[0002] The method of traditional buckle-type cantilevered scaffolding is usually to disconnect the scaffolding frame at a height of about 20m at intervals, and pre-embed U-shaped steel bars at the front and rear points of the cantilevered floor to fix 4-6m long I-shaped steel cantilevered out of the floor , Lay two longitudinal I-beams on the cantilevered I-beam (reason: the horizontal bar of the buckle scaffolding is a fixed modulus, and it is difficult to make the pre-embedded position of the cantilever I-beam accurate, and it is impossible to guarantee that each The cantilevered I-beam is just at the position of the pole of the buckle-type scaffold), and then a scaffold of the cantilevered section is re-built on the longitudinal I-beam, and the steel bar ring is pre-embedded on the floor above the cantilevered floor, and the wire rope Tighten the cantilevered I-beam and the lifting ring as insurance to achieve the purpose of unloading the cantilevered shelf body

The original technology wastes materials, is extremely inconvenient to install, requires a lot of manpower and cranes to cooperate with the operation, and the workload of pre-embedding and repair after dismantling is relatively large. When the cantilevered I-beam needs to pass through walls or beams and concrete will cause damage and affect the quality of the main structure
