The invention aims to provide a plugging device between a wall bushing and a template and a using method thereof, the plugging device can adapt to holes with various shapes generated between the wall bushing and the template, has good plugging effect, simple structure and convenient assembly and disassembly, and can be repeatedly used.
The technical scheme adopted by the invention is as follows:
the main body of the plugging device is an air bag, the air bag is in a long strip shape and can be encircled to form a ring, two ends of the air bag are respectively provided with a connecting piece, two ends of the air bag can be connected through the connecting pieces after the air bag is encircled to form the ring, a skirt edge is arranged along the long edge of one side of the air bag, through holes are distributed in the skirt edge, the air bag is provided with an inflation hole which can be closed and opened, and the inflation hole is positioned in an area except the bottom surface of the air bag.
Preferably, the air bag and the skirt are made of wear-resistant rubber.
Preferably, the attachment means is a fastener or a hook and loop.
The application method of the plugging device between the wall bushing and the formwork comprises the steps of firstly primarily inflating the air bag through the inflation hole, sealing the inflation hole after the effect is achieved, then sleeving the air bag on the wall bushing in a surrounding manner and connecting and fixing the air bag through connecting pieces at two ends, then adjusting the position of the air bag to enable the air bag to be attached to the formwork, then opening the inflation hole for secondary inflation, observing the state of the air bag until the outer ring of the air bag covers the opening of the formwork completely, then sealing the inflation hole, then fixing the skirt edge and the formwork through a through hole in the skirt edge by using a nail, then pouring concrete, taking out the nail before the initial setting of the concrete, and finally opening the inflation hole, unfastening the connecting piece and taking down the air bag after the concrete is solidified.
Preferably, the template is a wooden template.
The invention has the beneficial effects that:
the invention utilizes the expansion of the air bag to flexibly plug the hole of the template, not only can adapt to holes with various shapes generated between the wall bushing and the template, but also can be tightly attached to the wall bushing and the template, the air bag is sleeved on the wall bushing through connecting pieces at two ends, the air bag and the wall bushing are further tightly wrapped through inflation and expansion, and are fixed on the template through the skirt edge and the nail, thereby avoiding the pressure displacement, having good plugging effect, simple structure and convenient assembly and disassembly, and being capable of being repeatedly used.

Detailed Description
The invention is further described below with reference to the figures and examples.
As shown in fig. 1 to 3, the plugging device between the wall bushing and the template comprises a main body which is an air bag 4, wherein the air bag 4 is in a long strip shape and can be encircled to form a ring, two ends of the air bag 4 are respectively provided with a connecting piece 2, the two ends of the air bag 4 can be connected through the connecting piece 2 after being encircled to form the ring, a long edge of one side of the air bag 4 is provided with a skirt 3 along the line, through holes are distributed on the skirt 3, an inflating hole 1 which can be closed and opened is arranged on the air bag 4, and the inflating hole 1 is positioned in an area except the bottom surface of the air bag 4.
As shown in fig. 3, the use method of the plugging device between the wall bushing and the formwork comprises the following steps: firstly, primarily inflating the air bag 4 through the inflation hole 1, sealing the inflation hole 1 after the effect is achieved, then sleeving the air bag 4 on the wall bushing 5 and fixedly connecting the air bag 4 through the connecting pieces 2 at two ends, then adjusting the position of the air bag 4 to enable the air bag 4 to be attached to the template 6, then opening the inflation hole 1 to carry out secondary inflation, observing the state of the air bag 4 until the outer ring of the air bag 4 completely covers the hole of the template 6, sealing the inflation hole 1, then fixing the skirt 3 and the template 6 by penetrating a nail through hole in the skirt 3, then pouring concrete, taking out the nail before initial setting of the concrete, finally opening the inflation hole 1 after the concrete is solidified, unfastening the connecting pieces 2, and taking down the air bag 4.
In this embodiment, the form 6 is preferably a wooden form, the bladder 4 and the skirt 3 are preferably made of abrasion-resistant rubber, and the connecting member 2 is preferably a fastener or a hook-and-loop.
The invention utilizes the expansion of the air bag 4 to flexibly plug the hole of the template 6, not only can adapt to the holes with various shapes generated between the wall bushing 5 with various shapes and the template 6, but also can be tightly attached to the wall bushing 5 and the template 6, the air bag 4 is sleeved on the wall bushing 5 through the connecting pieces 2 at the two ends, the wall bushing 5 and the template 6 are further tightly wrapped through inflation expansion, and are fixed on the template 6 through the skirt 3 and nails, thereby avoiding the pressure displacement, having good plugging effect, simple structure and convenient assembly and disassembly, and can be repeatedly used.
