Description

Technical Field

[0001] The utility model relates to the technical field of scaffolds, in particular to a novel combined square steel tube scaffold. Background Art

[0002] In existing construction sites, two different sets of combined equipment are often used for formwork engineering and scaffolding engineering respectively to meet the different needs of work scenarios. They cannot be used interchangeably and can only be managed separately and used on demand. The excessive number of equipment puts great pressure on the management of the construction site. According to incomplete statistics, the service life of 80% of square steel pipes is less than 7 years, and the service life of the remaining 20% ​​will not exceed 15 years. In addition to the damage to components caused by incorrect installation and informal use, a considerable number of square steel pipes are directly lost or damaged due to improper storage management and transportation; on the other hand, the use scenarios are not interoperable, which makes it common for components to be vacant for a long time. For example, during the lap joint of the upper scaffolding, the lower formwork has been disassembled, and the formwork components are in a vacant state. At this time, the components cannot play their product functions, and the probability of loss will continue to increase with the extension of vacancy time.

The surface of the circular cross bars is uneven, and the cross bars cannot be limited when combined, and the stability of the cross bars cannot be guaranteed, which affects safety. Therefore, it is necessary to improve the scaffolding. Utility Model Content
