Background technique

The competition in today's construction field is becoming more and more fierce. In order to meet the needs of different architectural styles, roofs of different structures are continuously introduced, and the height of the roof frame is getting higher and higher. Most roof frames are set along the outer side of the roof structure during the design process. Multi-layer steel structure truss, and then construct glass curtain wall and other facade structures on the outside of the steel structure truss, so as to display the roof in a more atmospheric and beautiful image.

In the construction process of the roof curtain wall project, it is usually necessary to set up an external hanging basket for construction. The existing installation and dismantling process of the external hanging basket is usually to erect the front and rear brackets (vertically) of the hanging basket on the roof structural plate, and then install the hanging basket at the back. A counterweight is arranged at the bracket, and a horizontal bracket is erected on the upper end of the vertical bracket in a hinged connection mode. This process is restricted by the stable performance of the vertical support during use, so that the height of the hanging basket cannot be too large, resulting in a large safety hazard in the construction system of the external hanging basket after the curtain wall structure is higher than a certain height of the roof. At the same time, since the external hanging baskets are arranged on the roof structural panels, they occupy a large amount of roof space, which brings great inconvenience to the structural construction of the roof engineering and prolongs the construction period on site.
