Embodiment 1

[0037] This embodiment provides a detachable steel sleeve 001 reserved for openings on concrete slabs, please refer to figure 1 and figure 2 , this kind of detachable steel sleeve 001 reserved for openings on concrete slabs includes a sleeve body 100 and a positioning assembly 200; There is a gap between 110 , and each sleeve petal 110 is correspondingly provided with a mounting part 130 , and all the mounting parts 130 are detachably arranged on the positioning assembly 200 .

[0038] By splitting the casing body into pieces, the casing flaps 110 can be easily removed in pieces after the concrete outside the casing body 100 reaches strength. However, the sleeve flap 110 is easy to remove but not easy to fix. Therefore, the position of the sleeve flap 110 in the concrete molding process needs to be fixed through the positioning assembly 200 and the mounting piece 130 .

[0039] In this embodiment, the positioning assembly 200 includes a central positioning piece 230 and a l...

Embodiment 2

[0052] An installation method for the detachable steel sleeve 001 reserved for the opening of the concrete slab, which is to install the detachable steel sleeve 001 reserved for the opening of the concrete slab provided in Embodiment 1, including the steps of making the reserved for the opening of the concrete slab Detachable steel sleeve 001 and the detachable steel sleeve 001 reserved for the opening of the concrete slab surface:

[0053] Prepare detachable steel casing 001 for the opening of the concrete slab:

[0054] Cut the DN150×4.0 steel casing into three equal parts to form three casing valves 110;

[0055] Cut 50×4.0 flat steel (L=60mm) into three sections to form the mounting part 130, and grind one end of the mounting part 130 to make the mounting part 130 consistent with the inner curvature of the sleeve valve 110, so as to ensure reliable welding of the mounting part 130 and the sleeve valve 110, And cut the long waist hole 131 on the mounting part 130, and the ...

Abstract

The invention provides a detachable steel casing reserved for a hole in a concrete slab and an installation method thereof, belonging to the field of concrete construction tools, comprising a casing body and a positioning component; There is a gap between two adjacent sleeve petals, and each of the sleeve petals is correspondingly provided with a mounting part; all the mounting parts are detachably arranged on the positioning assembly. Through the detachable steel casing reserved for the opening of the concrete slab provided in this embodiment, when the casing body is removed, the locking part can be loosened and divided into pieces to shrink to the center to dismantle the casing flap, and the casing can be removed in pieces Flaps, and the change from the previous axial extraction to radial detachment can reduce the friction during extraction, on the one hand, it is easy to remove, on the other hand, it also avoids damage to the concrete. Moreover, the detachable steel casing is reserved for the hole of the concrete slab after it is taken out, which can be reused, which is green and environmentally friendly.

Description

technical field [0001] The invention relates to the field of concrete construction tools, in particular to a detachable steel sleeve reserved for openings on concrete slabs and an installation method thereof. Background technique [0002] Conventional concrete slab openings are reserved with PVC sleeves or steel sleeves. During the demolition process, the PVC sleeves are basically not recyclable; during the demolition process of the steel sleeves, affected by the strength of the concrete, it needs to be removed before the concrete reaches a certain strength. It is easy to damage the concrete opening during demolition, resulting in poor forming quality of the opening; if the concrete reaches a certain strength, the removal of the steel casing will take a lot of work and time, and the materials used cannot be recycled again. Contents of the invention [0003] The invention provides a detachable steel sleeve reserved for openings in concrete slabs and an installation method t...
