[0006] Furthermore, the sleeve is a galvanized steel pipe.

[0007] A fixing structure for reserved sleeves of mechanical and electrical engineering passing through walls and beams includes: a sleeve for mechanical and electrical engineering passing through walls or beams, a rubber and plastic insulation pipe filled inside the sleeve, a wall-piercing screw passing through the rubber and plastic insulation pipe and extending out of both ends of the sleeve, a butterfly clip arranged at both ends of the wall-piercing screw, and a fastening bolt fixed outside the butterfly clip; the central axes of the sleeve, the rubber and plastic insulation pipe and the wall-piercing screw coincide, and the length of the rubber and plastic insulation pipe is the same as the length of the sleeve; the sleeve passes through the gap of the structural steel bars of the wall or beam, and both ends correspond to the reserved holes on both sides of the formwork of the structural steel bars; both ends of the wall-piercing screw extend outside the formwork on both sides, and the butterfly clip is arranged outside the formwork for fixing the formwork.

[0008] Furthermore, the structural steel bars include vertical steel bars and horizontal steel bars, and the space between the structural steel bars is the space enclosed by the vertical steel bars and the horizontal steel bars.

[0009] Furthermore, the center line connecting the reserved holes on both sides of the formwork is horizontal, and the casing is arranged horizontally.

[0010] Furthermore, the outer walls of both ends of the casing are flush with the inner walls of the formwork on both sides.

[0011] The advantages and beneficial effects of the present utility model are:

[0012] The present utility model effectively solves the problems of displacement and falling off of the sleeves reserved for mechanical and electrical penetration through walls and beams during the construction process, and at the same time plays a role in strengthening the formwork, avoiding the occurrence of the phenomenon that the concrete blocks the sleeves due to the formwork bulging.

[0013] After the formwork of the wall and beam is removed, the tie rods, butterfly clips and the rubber and plastic thermal insulation filling in the sleeves can all be reused repeatedly, saving energy and protecting the environment. BRIEF DESCRIPTION OF THE DRAWINGS
