Example 4
A method for installing and removing a freely combined triangular lattice type supporting structure, wherein the installing step comprises the following steps: according to the conventional method, a formwork system is erected → a lattice type combined support model selection → a table lookup determination combined model → a lower vertical rod 2 is installed → a horizontal rod 4 connected with the lower vertical rod 2 → an adjusting screw rod 5 is installed → (a vertical rod 3 in installation → a horizontal rod 4 of a vertical rod 3 in installation) → an upper vertical rod 1 is installed → a horizontal rod 4 connected with the upper vertical rod 1 → an adjusting screw rod 6 is inserted → the top of the adjusting screw rod 6 is used for placing a batten and a bottom die, and the bottom of a structural beam 7 is supported.
After the installation is finished, the whole group of lattice type independent supporting structures are tightly supported at the bottom of the structural beam 7 through adjusting the adjusting screw rods 5 and the adjusting screw rods 6.
