Description

Technical Field

[0001] The invention relates to the field of scaffolds, in particular to a large-span telescopic scaffold. Background Art

[0002] Scaffolding is mainly used for the erection of frames with relatively small frame loads, such as the formwork used in the construction of standard floors in house construction.

[0003] In the process of house construction, the current scaffolding needs to be erected and spliced ​​to mainly erect the formwork frame.

[0004] The existing scaffolding formwork is set up and spliced ​​closely, which makes it too troublesome and time-consuming for workers to set up and dismantle the scaffolding, and the work efficiency is low. Therefore, a large-span telescopic scaffolding is proposed to address the above problems. Summary of the invention

[0005] In order to make up for the shortcomings of the prior art, such as low efficiency and insufficient standardization, and to solve the problem that the existing scaffolding is erected and spliced ​​densely, which makes it too troublesome and time-consuming for workers to erect and dismantle the scaffolding, the present invention proposes a large-span telescopic scaffolding to fundamentally solve the current situation of the scaffolding erection and dismantling industry.

[0006] The technical solution adopted by the present invention to solve its technical problem is: the large-span telescopic scaffolding described in the present invention includes a first fixed tube, a second fixed tube, an end buckle and two vertical poles; the first fixed tube and the second fixed tube are hollow inside, the inner wall of the first fixed tube is slidably connected to the second connecting tube, the inner wall of the second fixed tube is slidably connected to the first connecting tube, one end of the first connecting tube and the second connecting tube is fixedly connected to the end buckle, one end of the first fixed tube and the second fixed tube is fixedly connected to the end buckle, the surface of the vertical pole is clamped with the end buckle, the surface of the first fixed tube and the second fixed tube is fixedly installed with a fixing buckle, by loosening the fixing buckle from the first fixed tube and the second fixed tube, and then The first connecting tube and the second connecting tube slide in the first fixed tube and the second fixed tube, thereby adjusting the distance between the first fixed tube and the first connecting tube. After the first connecting tube and the second connecting tube are moved to appropriate positions, the fixing buckles are buckled on the first fixed tube and the second fixed tube, thereby holding the first connecting tube and the second connecting tube. Then, the two vertical poles are installed on the first fixed tube, the second fixed tube, the first connecting tube and the second connecting tube with the help of the end buckles, and then assembled into a scaffolding, which facilitates the assembly of the scaffolding. At the same time, because the distance between the first connecting tube and the first fixed tube becomes larger, the density of the scaffolding is reduced, thereby facilitating the erection and disassembly of the scaffolding.

[0007] Preferably, pin holes are evenly penetrated through the surfaces of the first fixing tube and the second fixing tube. When the pin is inserted into the pin hole, the pin will press the first connecting tube and the second connecting tube, thereby further fixing the first connecting tube and the second connecting tube in the first fixing tube and the second fixing tube.

[0008] Preferably, a slide groove is provided on the surface of the first fixed tube and the second fixed tube, and a first fixing frame is uniformly welded on the surface of the first connecting tube and the second connecting tube, and the first fixing frame is slidably connected to the inner wall of the slide groove. When the first connecting tube and the second connecting tube slide in the first fixed tube and the second fixed tube, the first fixing frame will slide with the first connecting tube and the second connecting tube, and the first fixing frame will also slide out of the slide groove. The first fixing frame plays a role of supporting the first connecting tube and the second connecting tube, thereby improving the stability of the first connecting tube and the second connecting tube.

[0009] Preferably, a second fixing frame is evenly and fixedly connected between the first fixing tube and the second fixing tube, and the first fixing tube and the second fixing tube are supported by the second fixing frame, so as to enhance the stability of the first fixing tube and the second fixing tube.

[0010] Preferably, the first fixing frame and the second fixing frame are in a claw shape. By arranging the first fixing frame and the second fixing frame in a claw shape, the stability of the first fixing frame and the second fixing frame can be enhanced.

[0011] Preferably, support frames are welded to the surfaces of the two vertical poles, and the support frames are in contact with the ground. The vertical poles are supported by the support frames in contact with the ground, thereby achieving the effect of enhancing the stability of the vertical poles.

[0012] Preferably, a bottom plate is fixedly mounted on the bottom end of the vertical pole, and the bottom plate is square. By placing the vertical pole on the ground, the bottom plate will contact the ground, and the contact area between the vertical pole and the ground is increased by the bottom plate, thereby achieving the effect of enhancing the stability of the vertical pole.

[0013] Preferably, the interiors of the first connecting tube and the second connecting tube are hollow. By arranging the interiors of the first connecting tube and the second connecting tube to be hollow, the weight of the first connecting tube and the second connecting tube can be reduced, thereby facilitating people to disassemble the first connecting tube and the second connecting tube.

[0014] The present invention is beneficial in that:

[0015] 1. By loosening the fixing buckle from the first fixing tube and the second fixing tube, and then sliding the first connecting tube and the second connecting tube in the first fixing tube and the second fixing tube, the distance between the first fixing tube and the first connecting tube is adjusted, until the first connecting tube and the second connecting tube are moved to a suitable position, the fixing buckle is buckled on the first fixing tube and the second fixing tube, thereby achieving the effect of holding the first connecting tube and the second connecting tube, and then the two vertical poles are installed on the first fixing tube, the second fixing tube, the first connecting tube and the second connecting tube by means of the end buckle, and then assembled into a scaffold, which facilitates the assembly of the scaffold. At the same time, because the distance between the first connecting tube and the first fixing tube becomes larger, the density of the scaffolding is reduced, thereby achieving the effect of facilitating the erection and disassembly of the scaffold.
