Description

Technical Field

[0001] The utility model relates to the field of building templates, in particular to a novel secondary structure quick-install and dismantle template structure. Background Art

[0002] The traditional formwork reinforcement mode has complicated processes such as early positioning, formwork matching, formwork support, and formwork removal, and the formwork is generally used only three to four times at most during construction before it can no longer be used. In the later stage, the formwork wood needs to be split and disposed of, resulting in a large amount of wood and formwork waste. The time and cost are huge. For this reason, the utility model provides a new type of secondary structure rapid installation and removal formwork structure. Utility Model Content

Then, tilt the formwork outward to disengage from the concrete surface. Then, lift it upward to remove the formwork. Then, clean the formwork. Finally, perform maintenance for recycling use.

[0021] The beneficial effects of the present utility model are as follows:

[0022] When the new secondary structure rapid formwork support and removal aluminum film structure is under construction, only construction positioning, formwork support, and formwork removal are required. Processes such as formwork matching and later splitting of formwork wooden squares can be omitted, which speeds up the construction progress and reduces the waste of lumber.
