Background technique

In the construction process of the main structure of high-rise building projects, with the increase of the main structure, scaffolding needs to be erected. Since the floor-standing scaffold is limited by height, after the main body rises to a certain height, a cantilevered scaffold is required. At present, the commonly used scaffolding is steel cantilevered double-row steel pipe scaffolding, that is, during the construction of this layer, U-shaped steel bar pull rings for anchorage are buried, and when the beam-slab concrete reaches a certain strength, cantilevered steel, cable-stayed steel wire ropes, frame etc.

According to the current regulations, the length of the fixed section of this kind of scaffold should not be less than 1.25 times the length of the cantilever section, and the amount of materials used is large, which is uneconomical. At the same time, when encountering columns and shear walls, it is necessary to reserve wall holes. After the scaffolding is removed, the reserved holes are inconvenient to repair, resulting in unsightly structure.

Utility model content

Technical solution: An integral cantilevered attached external scaffold described in the utility model includes a cantilevered I-beam and a tie rod, one end of the cantilevered I-beam is fixed on the building facade, and the other end is connected to the tie rod , the other end of the tie rod is fixed to the building facade by cable-staying.

To further improve the above technical solution, one end of the cantilevered I-beam is provided with a sealing steel plate, and this end is fixed on the facade of the building through the sealing steel plate and wall-through bolts or beam-through bolts.

Further, a stiffening plate is welded between the sealing steel plate and the cantilevered I-beam.

To further improve the above technical solution, the pull rod is provided with a height adjusting rod to adjust the length of the pull rod so that the pull rod is stressed.

Further, the two ends of the pull rod are respectively welded with connecting steel plates, the connecting steel plates at the upper end are fixed on the facade of the building through wall bolts or beam bolts, and the connecting steel plates at the lower end are connected with the steel plates on the cantilevered I-beams. Pieces perforated and pinned.

Further, the cantilevered I-beam is provided with a sleeve for fixing the upright, wherein: the sleeve for fixing the outer upright is located outside the steel sheet.

Compared with the prior art, the utility model has the beneficial effects as follows: the integral cantilevered attached external scaffold described in the utility model, (1) compared with the cantilevered scaffold commonly used at present, can be finished and is more beautiful, It meets the standardization requirements; (2) The overall cantilever saves the fixed section of the cantilevered I-beam, and uses less materials, which is more economical; (3) Because it is an overall external cantilever, there is no need to leave holes in the columns and shear walls. After the external scaffolding is removed, the external wall is more beautiful; (4) The installation is more convenient and the work efficiency is improved.

Detailed ways

The technical solutions of the utility model are described in detail below, but the protection scope of the utility model is not limited to the embodiments.

Embodiment 1: As shown in Figure 1, a kind of overall cantilevered attached external scaffolding includes cantilevered I-beam 3 and pull rod 7, and one end of said cantilevered I-beam 3 is provided with a sealing steel plate 9, and this end passes through The sealing steel plate 9 and the wall-through bolts 4 are fixed on the facade of the building, and upper and lower stiffening plates 10 are welded between the sealing steel plate 9 and the cantilevered I-beam 3 .

The pull rod 7 is provided with a height adjusting rod 5 to adjust the length of the pull rod so that the pull rod is stressed; the two ends of the pull rod 7 are respectively welded with a connecting steel plate 8, and the connecting steel plate 8 at the upper end is fixed to the On the building facade, the connecting steel plate 8 at the lower end is perforated and pinned with the steel sheet 6 on the cantilevered I-beam 3 .

A sleeve 12 for fixing the vertical rod 11 is arranged on the cantilevered I-beam 3, wherein the sleeve for fixing the outer vertical rod is located outside the steel sheet.

During construction:

1. According to the structure of the above-mentioned overall cantilevered attached external scaffold, the finished product is processed in the factory or on the construction site.

2. When the main body is constructed to the point where cantilevered scaffolding is required, the bushings are embedded in the part of the wall-penetrating screw for the passage of the wall-penetrating screw that fixes the cantilevered I-steel edge-sealed steel plate after the formwork is removed.
