Construction scheme for scaffolding and formwork of construction works
During the structural construction of the project, the inner scaffold adopts the bowl buckle type steel pipe scaffold system, and the outer scaffold adopts the hanging scaffold matched with the full steel large formwork; Hanging basket shall be used for exterior wall decoration. 1、 Bowl buckle type steel pipe scaffold system 1) Composition of scaffold system in bowl buckle steel pipe: The bowl buckle type steel pipe inner scaffold is composed of vertical pole, cross pole, top pole, diagonal pole, vertical pole pedestal, vertical pole adjustable seat, vertical pole connection lock, adjustable support, etc. Its core component is the bowl buckle joint. 2) Rack assembly method: (1) According to the actual situation of the project and the requirements of the specification, the spacing of the upright, the spacing of the cross bar and the height of the scaffold in the bowl buckle type steel pipe scaffold system of the project are all set as 0.9m, which is a heavy scaffold; (2) According to the plane characteristics and structural requirements of the building, the inner scaffold system is divided into two mutually independent parts, namely, both sides of the post cast strip and other areas. The scaffold system on both sides of the post cast strip shall be removed two months after the completion of the main structure. (3) A clear distance of 300-400mm shall be kept between the bowl buckle type steel pipe inner scaffold system and the external wall (or column) of the building to facilitate the installation and removal of formwork. (4) . In order to match the building module size, some 900 and 600 wide cross bars are prepared on site to adjust the overall size of the assembly frame.
