Height-adjustable overhanging-type double-row scaffold

Abstract

The invention discloses a height-adjustable overhanging-type double-row scaffold, and belongs to the technical field of civil engineering. The height-adjustable overhanging-type double-row scaffold comprises first I-shaped steel, six groups of second threaded rods are arranged on the front side and the rear side of the right end of the first I-shaped steel, pressing sheets are connected to the upper ends of the second threaded rods, second nuts are connected to the upper ends of the pressing sheets, the second nuts are connected with the second threaded rods, the upper end of the right side of the first I-shaped steel is connected with two second fixing frames, the upper ends of the second fixing frames are fixedly connected with second cylindrical sleeves, and the lower ends of threaded sleeves are fixedly connected into the second cylindrical sleeves. According to the height-adjustable overhanging-type double-row scaffold, on the basis of a traditional overhanging-type scaffold, a row of I-shaped steel is further arranged on a top floor slab, the installation stability of an overhanging frame can be guaranteed through the double I-shaped sheel, the I-shaped steel is all connected through a plurality of threaded rods, one ends of the threaded rods are embedded into a concrete floor slab in advance, the installation stability of the threaded rods is guaranteed, the upper I-shaped steel and the lower I-shaped steel are supported through the threaded sleeves and the threaded rods, the threaded rods are adjustable in height to adapt to different heights of different building floors, and the practicability is high.

Description

technical field [0001] The invention relates to the technical field of civil engineering, in particular to a height-adjustable cantilevered double-row scaffold. Background technique [0002] With the development of my country's economy and the needs of engineering construction, high-rise buildings and multi-storey buildings will gradually become the new wind vane of China's construction industry. Various buildings with complex structures and various forms bring more and more challenges and challenges to construction. problem. In order to meet the needs of different forms of building construction, different frame forms such as climbing frames and cantilever frames are gradually applied in various projects, and the construction technology and specifications are becoming more and more perfect. What form of frame is used for each project? Body plays a vital role in the safety, quality and economic benefits of construction enterprises. [0003] For projects with different floors...

Problems solved by technology

[0003] For projects with different floors and closely connected floors, if the climbing frame is used as construction scaffolding, it is time-consuming and laborious to use and assemble. Repeated disassembly and assembly according to different floor heights will affect the progress of the construction and safety cannot be guaranteed. Due to the flexible setting, the scaffolding can be erected at any time according to the needs. It is an ideal scaffolding for this kind of project. However, since the scaffolding body is borne by the cantilevered parts that cantilever out of the structure, it has higher requirements for installation safety. To ensure the reliable connection between the cantilever and the main structure is the premise to ensure safe construction. At the same time, the traditional cantilevered scaffold only has a row of I-beams on the ground, which has low safety structure and does not have a row of workers on the top floor. I-beams, and because different buildings lead to different floor heights, the height of the I-beams between the upper and lower sides cannot be adjusted, and the practicability is low
