AI Technical Summary

Technical Problem

During the existing construction, the support structure of the temporary opening of the floor slab is complex, with high cost and inconvenient construction.

Method used

A temporary hole insulating and sealing device for floor slabs is designed, including hole insulating device and hole insulating device. The hole opening insulating device combines the hole mold, pulling screw, upper and lower pipe clamps and bottom template to achieve the integration of the hole mold and bottom template, simplifying the positioning and disassembly of the bottom template. The opening sealing device uses a water stop screw, a rotary handle and a load-bearing steel to achieve the closing of the opening through the combination of the inner plate and the outer frame plate of the bottom formwork.

Benefits of technology

The device simplifies the construction process of opening retention and sealing, reduces construction costs, improves construction efficiency, and allows reuse of various components.

Abstract

The utility model relates to a floor temporary hole indwelling and plugging device, which comprises a hole forming die, an opposite-pull screw rod, an upper pipe clamp, a lower pipe clamp, an upper support pipe, a lower support pipe and a bottom template, a cross rod is arranged at the upper hole of the hole forming die, and the bottom template comprises an outer frame plate and an inner plate which can be detachably opened relative to the outer frame plate. A lower hole opening of the hole forming mold abuts against the upper plane of the inner plate to be sealed, and when the inner plate is opened or detached relative to the outer frame plate, the lower hole opening of the hole forming mold is exposed; the opposite-pull screw penetrates through the middle of the inner plate, the top of the opposite-pull screw extends out of an upper orifice of the pore-forming mold to be connected with an upper supporting pipe, an upper pipe clamp and a locking piece, the bottom of the opposite-pull screw extends out of the lower end face of the inner plate to be connected with a lower supporting pipe and a lower pipe clamp locking piece, and when the locking piece and the opposite-pull screw are locked, the pore-forming mold and the bottom mold plate are clamped; and the outer frame plate of the bottom template is connected with an embedded part which is embedded and fixed with the floor when the floor is poured. By means of the structure, disassembly, assembly and use are convenient, and repeated turnover use can be achieved.
