Abstract

The invention provides a step-back hole mold which comprises a hole frame sleeve, a reinforcing flange and a cover plate, wherein a plurality of inverted steps are formed on the outer wall of the holeframe sleeve and towards the outer side of the hole frame sleeve from bottom to top, the reinforcing flange is used for installing a hole formwork, the edges of a lower opening of the hole frame sleeve extend towards the inner side of the hole frame sleeve to form the reinforcing flange, and the reinforcing flange is arranged on the edges of the lower opening by a circle in the circumferential direction; and the cover plate is used for shielding an upper edge of the hole frame sleeve, and the cover plate can be foldably installed at the top of the hole frame sleeve. The step-back hole mold solves the problems of poor positioning effect, poor protection effect and easy water leakage of a traditional aluminum mold material transferring port mold.

Description

technical field [0001] The invention relates to the technical field of building construction, in particular to a step-down hole mold. Background technique [0002] With the rapid development of my country's housing construction industry in recent years and the influence of industry innovation drive, various industry tools and facilities are developing in the direction of high efficiency, convenience and reliability, and the finalized aluminum mold material transfer port mold is one of them. At present, the mold structure of the aluminum mold material transfer port is various. Generally speaking, openings are left on the aluminum mold template, and the steel box made of steel plate or angle steel is placed together. Slurry is formed during the concrete pouring process; secondly, the top of the steel box is open, which poses the risk of the upper part of the person falling and debris scattered, and the safety protection effect is poor; The cross-section is relatively simple, ...
