AI Technical Summary
Technical Problem
The existing embedded sleeves are difficult to remove after the concrete is poured, as they are bonded to the concrete floor slab. This results in the only option being destructive removal, making them unusable for reuse and increasing project costs and manual removal time.
Method used
The system employs a combination of rigid and flexible sleeves, connected by self-drilling screws. The rigid sleeve has a threaded opening in the middle for fixing to the roof slab template, while the flexible sleeve is fitted inside the rigid sleeve, enabling the pre-embedded sleeves to be removable and reused multiple times.
Benefits of technology
This enables easy removal and multiple uses of the pre-embedded sleeve, reducing project costs and manual removal time.

Abstract
The utility model discloses an embedded sleeve easy to dismantle and capable of being repeatedly used, which belongs to the field of building equipment and comprises a hard sleeve, a connecting piece is arranged in the middle of the hard sleeve, the connecting piece penetrates through the hard sleeve and then is connected with a roof plate template, and a soft sleeve is arranged on the outer side of the hard sleeve. According to the principle that the hard plastic sleeve is sleeved with the soft leather sleeve, the diameter and the height of the embedded sleeve are selected according to the diameter of a pipeline and the thickness of a floor slab in the later period before concrete pouring, the thread opening is reserved in the middle of the hard sleeve, and the self-drilling screw is screwed into the hard sleeve and fixed to a roof plate formwork. The hard sleeve is sleeved with the soft sleeve with the height equal to that of the hard sleeve and the diameter one larger than that of the hard sleeve, then the sleeve can be embedded, the connecting piece is loosened firstly in the dismantling process, the embedded sleeve can be dismantled easily, the embedded sleeve can be used repeatedly, and cost is saved.
