In order to reserve the hole in the poured concrete structure, it is necessary to pre-bury the sleeve pipe in the aluminum formwork before pouring.

[0003] When pre-burying the sleeve pipe, the traditional method is to weld and fix the sleeve pipe on the wall column reinforcement by the operator. This method needs welding operation, which has safety hazards. The position of each sleeve pipe in each standard layer needs to be repositioned and then welded and fixed. In addition, when the reinforcement deviates, the sleeve pipe will shift with the reinforcement, and the positioning will deviate. When the sleeve pipe deviates, only the welder can correct the problem, and ordinary operators cannot handle it. Therefore, the traditional sleeve pipe positioning method is time-consuming, labor-intensive and prone to positioning deviation.

[0004] In order to make up for the lack of sleeve pipe pre-burying accuracy and reduce the amount of manual use, a telescopic sleeve pipe positioning mold suitable for aluminum formwork is needed to improve the accuracy of sleeve pipe pre-burying. UTILITY MODEL CONTENTS
