technical field

The utility model belongs to the technical field of building formwork construction, in particular to an aluminum alloy formwork pre-assembled anti-dismantling embedded part structure.

Background technique

With the popularization of aluminum alloy formwork construction technology, the characteristics of high profile accuracy and firm positioning can be used for installation and construction. However, in the existing construction, for the aluminum alloy formwork that needs to be anchored in concrete, one method is to drill holes on site after pouring and curing the concrete structure, and the other is to construct after the embedded parts are installed. Most of the existing embedded parts are embedded by connecting the embedded slab to the outside of the concrete structure, which needs to be removed later. After the aluminum formwork is demolished, the embedded parts are manually fixed to the concrete surface by means of drilling or expansion bolts. The existing embedded parts still come out first, and they fall off or deviate with the removal of the formwork. The later installation of the protective railings requires secondary drilling or bolting. Therefore, it is necessary to provide a pre-embedded part that does not need to be removed.
