Embodiment 1

[0021] like Figure 1-9 As shown, the square steel pipe lift-type external scaffold of the present invention is composed of a lifting beam 1, a vertical main frame 2, a horizontal support frame, a frame body 3 and an anti-falling device, and the lifting beam 1 is composed of a hanging plate 4 and a channel steel 5 The hanging plate 4 is fixedly connected with the outer wall through at least two wall-through bolts, the channel steel 5 is connected with the hanging plate 4, and the root is fixedly connected with a reinforced triangular plate 6; the middle part of the lifting beam 1 is provided with an anti-falling device, and a control panel is installed below it. An electric hoist with a lifting frame; the end of the lifting beam 1 is welded with a channel steel baffle 7, and the baffle 7 is connected with a guide wheel 8, and the guide wheel 8 is located in the groove of the channel steel guide rail 9 of the vertical main frame 2. The sliding contact connection of the guide ra...

Embodiment 2

[0023] The square steel pipe lifting type external scaffolding of the present invention is used for the decoration of the face wall and external wall of the existing building. The scaffolding is a plane structure, and the height is three floors high of the building floor height, which is about 12.6 meters.

Embodiment 3

[0025] The square steel pipe lifting type external scaffolding of the present invention is used for building new buildings, and the scaffolding is a square structure, and the height is 5 floors high of the building floor height, which is about 16.2 meters.

Abstract

The invention relates to a square steel tube lifting scaffold for high altitude operation of building construction, which is composed of lifting beams, a vertical main frame, a horizontal bearer frame, a scaffold body and anti-fall devices. The outside scaffold is characterized in that at least three lifting beams are arranged to integrally lift the whole scaffold; the anti-fall devices are arranged in the middle of the lifting beams; and an electric hoist is installed below the lifting beams for controlling the lift of the scaffold body. When the scaffold body is needed to be lifted, a hinge of the electric hoist is loosened, the electric hoist is started so as to lift the whole scaffold body. When lifted to the position, the electric hoist is fixed by the hinge, if the hinge for fixing the electric hoist is broken or cracked, the spring of the anti-fall devices which bears the weight of the electric hoist bounces, a wedge-shaped card falls down to clamp the main frame guide rail, thereby effectively preventing the whole scaffold body from falling.

Description

technical field [0001] The invention relates to a square steel pipe construction high-altitude operation lifting type scaffolding. technical background [0002] The existing steel pipe scaffolding with fasteners is constructed by connecting round steel pipes with fasteners. The on-site installation process of this kind of scaffolding is cumbersome, time-consuming, low in safety factor, large in steel consumption, and pollutes the construction site environment. The workload is heavy and the fastener loss is large. Contents of the invention [0003] The purpose of the present invention is to overcome the technical defects of the existing scaffolding, and provide a lift-type external scaffolding that is easy to use, light in weight, high in safety factor, and less polluting to the construction environment. [0004] The square steel pipe lift-type external scaffolding of the present invention is composed of a lifting beam, a vertical main frame, a horizontal support frame,...
