Problems solved by technology

Not only the cantilever length and coverage area are limited, but also the bearing capacity and impact resistance are small, and it also brings hidden dangers to the safe use of scaffolding under the action of wind load. It is dangerous to install and disassemble, and all the materials used cannot be reused.

Embodiment 1

[0030] The prefabricated cantilever safety shed for high-rise building construction is composed of a cantilever main beam 6, a horizontal cross bar, a protective railing 5, a force-bearing joint seat 3, an anti-tension anchor seat 4, and an anti-tension steel wire rope 2. For the cantilevered girders, horizontal bars and protective railings of the double-layer protective shed 1, scaffolding steel pipes of Φ48×3.5 are used. The cantilevered girder, the horizontal cross bar and the protective railing are connected to form a double-layer protective shed 1 . Two anti-pull points are set on the cantilever main beam, and the two anti-pull points divide the cantilever main beam from one end of the welding movable plug-in to the other end into L 1 , L 2 , L 3 Three paragraphs, L 1 : L 2 : L 3 =1:0.8:0.41.

[0031] The stressed hinge seat is composed of hinge components, bolts and steel plates, and the hinge components are fixed on the main structure of the building through screw...

Embodiment 2

[0034] The construction method of building a prefabricated cantilever safety shed for high-rise building construction:

[0035] (1) Prepare the rods and stress hinge seats 3, anti-tension anchor seats 4, and anti-tension steel wire ropes 2 for the construction of high-rise building construction assembly-type cantilevered safety shelters, using Φ48×3.5 scaffolding steel pipes as the main cantilever The bar material that beam 6, horizontal bar, protective railing 5 are useful, all brush two~three antirust paints after derusting the assembled hinge assembly of stressed joint seat.

[0036] (2) In the main structure of the building, the PVC casing 8 of the stressed hinge seat and the tie round steel of the anti-tension anchor seat are pre-embedded. The PVC casing and the tie round steel are on the same vertical plane, and the tie circle The distance between the top and bottom of the steel and PVC casing is 5-6m, and the distance between the levels is less than 3m.

Abstract

The invention discloses a high-rise building construction assembled overhanging safe guarding shed and a construction method thereof. The safe guarding shed is built by an overhanging main beam, a horizontal cross rod, a protective barrier, a stressed hinged seat, a reverse-drawing anchoring seat, a pull-back cable and the like, wherein, the overhanging main beam, the horizontal cross rod and the protective barrier are connected with each other to form a double-layer guarding shed, the stressed hinged seat and the reverse-drawing anchoring seat are respectively fixed on the main structure of the building, and one end of the overhanging main beam is connected with the stressed hinged seat; one end of the pull-back cable is connected with the reverse-drawing anchoring seat, and the other end thereof is connected with a reverse-drawing point arranged on the overhanging main beam. The safe guarding shed has simple and reasonable structure as well as simple and convenient method, leads the main beam of the shed body to be directly attached on the main structure of the building and extended to be a whole by assembly, and overcomes the defects of the traditional guarding shed, so as to improve the bearing capacity and shock resistant strength of the guarding shed, ensure the construction to be safe and be convenient and fast in mounting and demounting.

Description

technical field [0001] The invention relates to a prefabricated cantilevered safety protection shed and a construction method that can be erected in sections according to the height of high-rise building construction to prevent the occurrence of impact accidents caused by falling objects during the construction of high-rise buildings, belonging to the technical field of building construction. Background technique [0002] Along with the development of urban construction, the building construction site is narrower and narrower, and the accident of hurting people and things by falling objects often occurs in the construction of high-rise buildings. During the construction of the main structure of high-rise buildings, with the height of high-rise building construction, erecting safety shelters in sections is one of the most effective measures to prevent accidents caused by falling objects, especially for street-facing buildings. Traditional protective sheds are suspended on the...
