Embodiment

[0022] Such as figure 1As shown, the exterior wall hole sealing formwork provided in this embodiment includes exterior wall formwork 1 and interior wall formwork 4 arranged at intervals, the exterior wall formwork 1 is a flexible airbag with an inflatable cavity inside, and the exterior wall formwork 1 After being inflated, it is in the shape of a cube. An inflatable nozzle 2 is provided on the side of the exterior wall formwork 1 facing the interior wall formwork 4. An inflatable tube 3 for inflating the exterior wall formwork 1 is detachably connected to the inflatable nozzle 2. The inflatable tube 3 is a rigid tube, and its end is inclined upward; the interior wall formwork 4 is vertically arranged, and a grout discharge pipe 44 and a grouting pipe 45 passing through the interior wall formwork 4 are arranged at intervals up and down on the front end of the interior wall formwork 4 After the end of the inflation pipe 3 passes through the interior wall formwork, it is fixed o...

Abstract

The invention discloses an outer wall hole plugging formwork and an outer wall hole plugging method. An outer wall formwork of the hole plugging formwork is made of a flexible air bag, an air nozzle is arranged at the front end of the outer wall formwork, an inflation pipe is connected to the air nozzle, and the outer wall formwork can be in different states by inflating and deflating the inflation pipe; after inflation, the whole outer wall formwork is in a cube shape and is used as the formwork for plugging the outer side of a hole; and after exhaust or when inflation is not carried out, the whole size of the outer wall formwork is smaller, and the inflation pipe can drive the outer wall formwork to penetrate through the hole to be plugged together. An inner wall formwork is arranged at the front end of the inflation pipe in a sleeving manner, the inflation pipe is used as an opposite-pulling lead screw, and pulling, connecting and fixing of the outer wall formwork and the inner wall formwork are achieved; and a grouting pipe and a slurry discharging pipe are arranged on the inner wall formwork, so that the hole is grouted and blocked through the grouting pipe on the inner wall formwork.

Description

technical field [0001] The invention belongs to the field of building construction, and in particular relates to an exterior wall hole sealing formwork and an exterior wall hole sealing method. Background technique [0002] At present, when sealing the construction holes of the outer wall, it is usually necessary to set an outer formwork on the side of the outer wall and an inner formwork on the side of the inner wall, and fix the outer formwork and the inner formwork by a pair of drawing rods. After opening holes in the inner formwork, grout into the construction holes until the plugging is completed, and then remove the formwork. The above-mentioned construction method requires the external surface treatment and the external scaffolding to provide the working surface, but in most cases, due to many reasons such as tight construction schedules and site conditions, the wall holes cannot be blocked in time before the external scaffolding is removed. [0003] In order to solv...
