A formwork structure and sealing method for sealing the reserved opening of the outer wall

Abstract

The invention discloses a formwork structure and a sealing method for sealing a reserved hole in an outer wall. The formwork structure includes an outer formwork and an inner formwork arranged on both sides of the reserved opening on the outer wall. The outer formwork is composed of The foldable formwork composed of two symmetrical formworks is hinged. The upper end of the inner formwork is provided with a pouring port. The four corners of the outer formwork and the inner formwork are respectively provided with a first through hole and a second through hole. After the first through hole and the second through hole, the outer template and the inner template are tied and fixed. The outer formwork and the inner formwork of the present invention are mutually tied and fixed by iron wires. Therefore, no additional brackets for supporting the formwork are required, which not only saves time and labor, but also saves construction costs and greatly improves construction efficiency.

Description

technical field [0001] The invention relates to a formwork structure and a sealing method for sealing a reserved opening of an outer wall, belonging to the technical field of building construction. Background technique [0002] In the later stage of building construction, the reserved holes on the outer wall need to be sealed. Generally, formwork is supported on both sides of the reserved holes, and then concrete is poured for sealing. However, this sealing method needs to set up brackets for supporting the formwork on both sides of the outer wall, especially the outer side brackets of the outer wall. As the height of the floor increases, the more pipe fittings and fasteners used to erect the brackets, the higher the brackets will be. It will inevitably lead to poor structural stability and potential safety hazards, and it takes time and effort to erect the bracket, which increases the difficulty of construction. In addition, the existing templates used for sealing the rese...

However, this sealing method needs to set up brackets for supporting the formwork on both sides of the outer wall, especially the outer side brackets of the outer wall. As the height of the floor increases, the more pipe fittings and fasteners used to erect the brackets, the higher the brackets will be. It will inevitably lead to poor structural stability and potential safety hazards, and it takes time and effort to erect the bracket, which increases the difficulty of construction

In addition, the existing templates used to block the reserved openings are all used as one-time templates and cannot be reused, resulting in increased construction costs
