Problems solved by technology

However, if the existing construction method is improperly constructed between the roof opening and the roof slab, the bottom of the opening is prone to expansion and grout leakage, the upper part of the opening is prone to cracks, and the surface is uneven, and the steel pipe frame is supported by the formwork. This construction process is complicated. , poor waterproof ability, high cost of use, and the support parts cannot be adjusted

Abstract

The invention discloses a roof reserved opening concrete sealing and blocking device and a fabrication method thereof. The roof reserved opening concrete sealing and blocking device comprises a roof floor and a reserved opening, the reserved opening is formed in the surface of the roof floor, and pre-pouring concrete is arranged at the periphery of the reserved opening. A plurality of snap-in rodsare arranged in the pre-pouring concrete in an embedded mode, the snap-in rods are all arranged at the front corner of the reserved opening in an embedded mode, and screw rods are welded to one endsof the snap-in rods. The roof reserved opening concrete sealing and blocking device has simple fabrication, the installation of the three-section water stop screw rods of a template supporting component is safe and reliable, and reusing is achieved; then under a bad environment, the leakage risk of the reserved construction opening can be reduced through the arrangement of waterproof sleeving pipes and plate penetrating pipes, so that the effects that the surface of the concrete is smooth, the compactness is good, and secondary repair is not required are achieved, and the construction progressis improved are achieved; and in addition, the operation table is simple and practical, so that popularization in a wide range is facilitated.

Description

technical field [0001] The invention relates to the technical field of building construction, in particular to a concrete sealing device for a reserved hole in a roof and a manufacturing method thereof. Background technique [0002] In construction engineering, in order to meet the construction needs of the main structure of the building, electrical, kitchen and bathroom, and construction openings are usually reserved in the floors. After the main structure is completed, the openings are blocked, but it will be found that Due to improper handling of the projects put into use, it is easy to cause cracks to form around the holes, which will affect the appearance of the building surface, and there will be quality problems of leakage in some parts with water. Especially the manholes, chimneys, and exhaust holes reserved on the roof. If these holes are improperly sealed, it will not only affect the strength and integrity of the concrete around the roof openings, but also affect t...
