Sleeve assembly for reserved hole of building floor and mounting and using method thereof

Abstract

The invention discloses a sleeve assembly for a reserved hole of a building floor and a mounting and using method thereof. The sleeve assembly comprises a sleeve with openings at two ends, an annular boss is integrally arranged on the inner side wall of a port at the lower end of the sleeve, strip-shaped fixing gaskets are uniformly distributed on the lower end surface of the sleeve, one ends of the fixing gaskets are fixedly connected to the lower end face of the sleeve, and the other ends of the fixing gaskets are located on the outer side of the sleeve; an eccentric gasket is movably sleeved with the sleeve and is of an annular structure formed by splicing two C-shaped gaskets; the sleeve can be rapidly fixed to a formwork through the fixing gaskets, after concrete is poured outside the sleeve, the concrete is fixedly connected with the sleeve, the reserved hole is formed inside the sleeve, the sleeve does not need to be disassembled in the later period, and manpower and material resources are saved; and the eccentric gasket is matched between the sleeve and a fixed pipeline for plugging, the operation is simple and time-saving and labor-saving, and the working efficiency is improved. The sleeve assembly is simple in overall structure, stable in structure, low in cost and convenient to install and use.

Description

technical field [0001] The invention relates to the field of construction engineering, in particular to a bushing assembly used to reserve holes in building floors and an installation and use method thereof. Background technique [0002] In construction projects at this stage, the use of formwork construction is more common. Steel bars are bound on the formwork, concrete is poured to form a floor slab, and holes need to be reserved for various pipes before pouring concrete. At present, the more common method is to make the formwork box with reserved holes first, and fix the formwork box with reserved holes at a specific position, then pour concrete, remove the formwork box with reserved holes after the concrete is set, and install the pipeline with the It is time-consuming, labor-intensive, and material-intensive to seal the gaps between the concrete by lifting the formwork, and when the formwork box with reserved holes is removed, it is easy to damage the concrete, resultin...
