Description

Description: TECHNICAL FIELD The present invention relates to a closing frame for closing a through hole of a building such as a house and a method for closing the through hole, and particularly good followability with the through hole. The present invention relates to a closing frame which closes a through hole of a building such as a house and a method of closing the through hole, which is capable of improving not only the workability of closing but also the connecting property with the through hole.

<Prior Art> Conventionally, through-holes for passing passage bodies such as water supply and drainage pipes and cables have been formed in walls and foundations of buildings such as houses and buildings.

By the way, the through hole of the building such as the house is a void portion of the through hole because it is necessary to prevent fire or dust when the passage body such as the water supply / drainage pipe or the cable is not passed or when the passage body is passed. Is filled with a filler such as concrete or mortar, thereby closing the void portion of the through hole.

Then, conventionally, as a method of closing the void portion of the through hole, a backing material made of plywood, a steel plate, or the like is applied to the outer edge on the opposite side of the through hole, and the filler is prevented from spilling on the opposite side. The through hole was filled with a filler to close the void portion of the through hole.

However, in such a conventional method, in order to prevent the filler from spilling on the opposite side, a backing material made of plywood, steel plate or the like must be applied to the outer edge on the opposite side of the through hole. Since the work is complicated on both sides, not only the work is complicated, but also the backing material needs to be peeled off after closing the through hole, resulting in a problem that work efficiency is insufficient.

Therefore, as a conventional method for improving work efficiency, a method has been proposed in which a tea-tube-shaped closing member is inserted into the through hole, and then the closing member is filled with a filler to close the through hole. In the method, since the through hole and the filling material do not come into direct contact with each other, the bondability between the through hole, the closing body, and the filling material is lacking, and the bottom surface of the closing body must be supported. There is a problem in that the work is complicated on both sides of the through hole, and the work is complicated, and the problem still remains.
Further, in such a method, there is a problem that the through holes of various sizes cannot be followed and the number of types of the closing body increases.

<Problems to be Solved by the Invention> In view of the problems of the prior art as described above, the main object of the present invention is to eliminate the complexity of the work due to the double-sided work of the through hole, It is possible to deal with it only by one-sided work, and further improve the bondability between the through hole, the closing body, and the filling material, and it is possible to widely follow through holes of various sizes. It is an object of the present invention to provide a closing frame that closes a through hole of a building such as an inexpensive house that can dramatically improve the cost and a method of closing the through hole.

<Means for Solving Problems> According to the present invention, such an object is formed of a perforated material such as a metal mesh material provided with a large number of holes, and is formed into a bottomed cylindrical shape with one end opened. In addition, the outer diameter of the cylinder is formed to a diameter that can be inserted into the through hole of a building such as a house, and a closing frame for closing the through hole of the building such as a house, and a large number of holes. After inserting a closed frame formed of a perforated material such as a metal mesh material and having a one-end opening into a through hole, the inside of the closed frame is filled with a filling material such as concrete or mortar. Then, the through hole is closed, and thereby the filler and the inner wall of the through hole are coupled to each other, thereby providing a method for closing the through hole of a building such as a house. .

<Operation> As described above, according to the present invention, a tubular closing frame made of a perforated material such as a metal mesh material, and the above-mentioned closing frame inserted into a through hole, and a filling material inside the closing frame. To improve the workability of closing and to improve the bondability between the through hole, the closing frame and the filling material by using a method of filling the through hole and closing the through hole of a building such as a house. You can

That is, the pre-work for filling the through hole with the filling material is
It can be performed by inserting the closing frame into the through hole without performing the backing work which has been performed conventionally.

Further, the closing frame is made of a perforating material such as punching metal or metal net material having a large number of holes, and has a large joint area between the filler and the through-hole (conversely, between the filler and the through-hole). Since there are few unbonded parts), by filling the inside of the closed frame with a filler such as concrete or mortar, excellent connectivity between the filler and the through holes can be obtained. And can be firmly bonded.

Further, in the case where the opening end of the cylindrical body is provided with an engaging piece that engages with the outer edge of the through hole on the front side, the engaging piece should be engaged with the outer edge of the through hole on the front side. Thus, the closing frame and the through hole can be engaged with each other, and the through hole and the closing frame can be surely and easily engaged with each other.

Further, in the case where the bottom of the cylindrical body is provided with a passage hole formed so as to pass through a passage body such as a water supply / drain pipe or a cable, after inserting the passage body into the passage hole, By inserting the closing frame into the hole, the closing frame can be used also in the through hole in which a passage body such as a water supply / drainage pipe or a cable is arranged.

Further, in the case of being separable or separable by the separating portion or the dividing portion formed along the axial direction, even if the size of the through hole is various. , Or even if the size of the passage body such as the water supply / drainage pipe or the cable to be inserted into the passage hole is various, when the closing frame is inserted into the through hole, or the passage body is inserted into the passage hole. At this time, by further opening or closing the separating part or the dividing part of the closing frame, the outer diameter of the tubular body can be inserted into the through hole, or the inner diameter of the passage hole can be changed to a diameter into which the passage body can be inserted. As described above, the closing frame can be inserted into the through hole or the passage body can be inserted into the passage hole by changing the respective shapes.
