Embodiment 1

[0017] In this embodiment, the fixing device is composed of a cantilever rod 1, a strut 2, a corner ring 3, and a sleeve 6. The corner ring 3 is fixed on the beam 22, the cantilever rod 1 is fixed on the corner ring 3, the strut is connected with the cantilever rod 1 through the sleeve 6, and the other end is fixed to the corner ring 3 on the beam 22 of the next floor .

[0018] Workbench is made of foot bar 7, frame cross bar 9, frame side bar 10, scaffold board 11, tractor 13, suspension ring 14, traction rope 15, safety guardrail 12 constitutes, in the present embodiment, two of frame cross bar 9 There is a tenon at the end, and there is a tenon at the two ends of the frame side bar 10, and there is a tenon at the two ends of the foot bar 7, and they are connected by tenon and tenon. The middle layer has tractor 13, traction rope 15, suspension ring 14 control. Constitute a cuboid frame with three horizontal planes, the scaffold board 11 is placed on the three horizontal ...

Embodiment 2

[0022] In this embodiment, the workbench has seven working surfaces. During the construction process, the workbench is placed directly on the ground to complete the construction of five floors, as shown in Figure 9. When the workbench needs to be lifted, the middle layer is raised above the beams of the second floor through the tractor 13, and then the ground corner ring 3 is installed on the beams 22 of the first and second floors, and through the sleeve 6 Fix the cantilever rod 1 on the first and second floor beams 22, so that the middle layer can be placed on the cantilever rod 1 of the second floor beam 22. At this time, the tractor 13 is started to move the middle layer downward. When the floor cannot be used downward after being resisted by the cantilever rod 1 on the beam, the upper and lower floors of the workbench will be lifted up at the same time. When the bottom of the lower floor is higher than the beam 22 of the first floor, the connecting rod 18 connecting bolt...

Abstract

The invention belongs to a scaffold used for building construction, aims to provide a cantilever lifting scaffold which utilizes beams to support the scaffold. The scaffold consists of a fixing device and a worktable, wherein, a scaffold foot lever, a scaffold cross lever and scaffold side levers are connected to form a rectangular frame which is provided with three to seven horizontal planes; the upper layer and the lower layer of the frame are tightly fixed; and the intermediate layer can move between the upper layer and the lower layer due to the action of a retractor and so on. A cantilever is utilized for supporting the scaffold, the scaffold and a point under stress are made to always maintain the minimum distance, and the scaffold is not required to be assembled and disassembled repeatedly when used, thereby the labor intensity of workers is lightened and the economic benefit is improved; and scaffold workers always operate on the worktable need not aloft work, thereby the safety factor is improved and buildings are not damaged.

Description

[technical field] [0001] The invention belongs to a scaffold used for building construction, in particular to a scaffold fixed on a building beam. [Background technique] [0002] Traditional scaffolding is generally built from the ground until it is capped with the building. This structure requires a lot of materials and labor, and it is particularly disadvantageous in the construction of high-rise buildings. In recent years, in order to overcome the shortcomings of traditional scaffolding, some new improvements have appeared. Such as the Chinese patent "high-rise building hoop-type lifting scaffold" that the patent application number is 200420026604.5, and the Chinese patent "segmentable integral lifting scaffold" that the patent application number is 200320123230.4. These technologies have overcome the shortcomings of traditional scaffolding from the ground to the top of the building. Fixing the scaffolding to the pillars or walls of the building does save some materials ...
