Description

[Detailed Description of the Invention] <Industrial Application Field> The present invention relates to a closing frame for closing a through-hole in a building such as a house, and a method for closing the through-hole, and particularly to a closing frame that has good followability with the through-hole. The present invention relates to a closing frame for closing a through hole in a building such as a house, and a method for closing the through hole, which can improve the closing workability and improve the connectivity with the through hole.

<Conventional Technology> Conventionally, in the walls and foundations of buildings such as houses and buildings, through holes are provided for passage of objects such as water supply and drainage pipes and cables.

By the way, when the through-holes of buildings such as the above-mentioned houses do not allow objects such as water supply and drainage pipes or cables to pass through them, or when such objects do pass through them, due to the necessity of fire prevention and dust prevention, the voids of the through-holes are A filler material such as concrete or mortar is filled in the through hole, thereby closing the void portion of the through hole.

Conventionally, the method for closing the gap in the through hole is to apply a guard made of plywood, steel plate, etc. to the outer edge on the other side of the through hole to prevent the filler from spilling on the other side, and then
The through hole was filled with a filler to close the gap in the through hole.

However, in such conventional methods, in order to prevent the filling material from spilling on the other side, it is necessary to apply a backing material made of plywood, steel plate, etc. to the outer edge of the other side of the through hole. Not only does the work have to be done on both sides of the hole, which makes the work complicated, but it also becomes necessary to peel off the guard material after closing the through hole, resulting in a problem of a lack of work efficiency.

For this reason, as a method to improve work efficiency, a method has been proposed in the past in which a tea caddy-shaped closing body is inserted into the through-hole, and then the closing body is filled with a filler to close the through-hole. In this method, since the through hole and the filling material do not come into direct contact, there is a lack of bonding between the through hole, the closing body, and the filling material, and the bottom surface of the closing body must be supported. However, this method still has the problem that the work must be done on both sides of the through-hole, making the work complicated.Furthermore, in this method, it is difficult to follow through-holes of various sizes. However, there was a problem in that the number of types of closure bodies increased.

<Problems to be Solved by the Invention> In view of these problems in the prior art, the main purpose of the present invention is to eliminate the complexity of work required to work on both sides of the through hole, and to It can be handled by only one-sided work, and it also improves the connectivity between the through hole, the closing body, and the filling material, and can be applied to a wide range of through holes of various sizes.The synergistic effect of these makes it possible to improve the workability of the closing work. It is an object of the present invention to provide a closing frame for closing a through hole in a building such as an inexpensive house and a method for closing the through hole, which can dramatically improve the performance.

<Means for Solving the Problems> According to the present invention, this object is made of a perforated material such as a metal mesh material provided with a large number of holes, and formed into a bottomed cylindrical shape with an open end. A cooling frame for closing a through-hole in a building such as a house, and a large number of After inserting a closing frame made of a perforated material such as a metal mesh material with holes and formed into a cylinder shape with an open end at one end into the through hole, a filler such as concrete or mortar is placed inside the closing frame. This is achieved by providing a method for closing a through hole in a building such as a house, which is characterized by filling the through hole with the filling material, thereby joining the filling material to the inner wall of the through hole. Ru.

<Function> As described above, according to the present invention, a cylindrical closing frame made of a perforated material such as a metal mesh material, the closing frame is inserted into a through hole, and a filling material is placed inside the closing frame. By using a method of filling through-holes in buildings such as houses and the like, the workability of the closing work is dramatically improved, and the connectivity between the through-holes, the closing frame, and the filling material is improved. I can do it.

In other words, the pre-work for filling the through hole with filler material is as follows:
This can be done by inserting a closing frame into the through hole without performing the conventional backing work.

In addition, the closing frame is made of a perforated material such as punched metal or metal mesh material with a large number of holes, and the bonding area between the filling material and the through hole is large (in other words, the area between the filling material and the through hole is large). By filling the inside of the closing frame with a filler such as concrete or mortar, excellent bonding properties between the filler and the through-hole can be obtained. and can be strongly combined.

Furthermore, if the opening end of the cylinder is provided with an engagement piece that engages with the outer edge of the front side of the through hole, the engagement piece should be engaged with the outer edge of the front side of the through hole. The closing frame and the through-hole can be engaged with each other, and the through-hole and the closing frame can be engaged with each other reliably and easily.

In addition, if the bottom of the cylindrical body is provided with a passage hole that is formed so that a passage object such as a water supply and drainage pipe or a cable can pass through, after inserting the passage object into the passage hole, By inserting the closing frame into the hole, the closing frame can also be used for a through hole in which a passing body such as a water supply/drainage pipe or a cable is disposed.

In addition, in the case of a device that is separable or divisible by a separating portion or a dividing portion that is separated along the axial direction, the size of the through hole may be various. , or even if the size of the passing object such as a water supply/drainage pipe or cable to be inserted into the passing hole is various, when inserting the closing frame into the through hole, or when inserting the passing object into the passing hole. At this time, by opening or closing the separating section or dividing section of the closing frame further, the outer diameter of the cylindrical body can be adjusted to a diameter that allows insertion into the through hole, or the inner diameter of the passage hole is adjusted to a diameter that allows the passage object to be inserted. Thus, the closing frame can be inserted into the through hole, or the passage body can be inserted into the passage hole, respectively, with the following changes.

That is, unlike the first embodiment, the opening 4 has an outer edge C on the front side of the through hole a (the front side of the partition member p of the wall or foundation of the building in which the through hole a is formed). An engaging piece 5 that engages with is provided.

At this time, the preliminary work for filling the through hole a with the filler material is to insert the closing frame 1 into the through hole a, and to engage the engaging piece 5 with the outer edge C on the front side of the through hole a. Not only does this eliminate the need for the conventional backing work and only requires work on one side of the outer edge on the front side of the through hole, but also the closing frame 1 in the first embodiment
This eliminates the need for temporary fixing work, making the closing work simple and reliable.

Next, the inside of the closing frame 1 is filled with a filler such as concrete or mortar to close the through hole a, thereby connecting the filler and the through hole a.

Therefore, not only is it unnecessary to temporarily fix the through hole a and the closing frame 1 using a filler, adhesive, or other bonding material, which was required in the first embodiment, but also the through hole a
The engagement between the closing frame 1 and the closing frame 1 becomes simple and reliable.

That is, unlike the above-mentioned embodiment, the bottom part 3 has a flange 6 formed upright with the center of the bottom part 3 facing inward of the cylindrical body 2 so that passage objects t such as water supply and drainage pipes and cables can pass therethrough. , a passage hole 7 through which the passage body t can pass is formed.

At this time, the preliminary work for filling the through hole a with the filler material is as follows:
This can be done by passing a passage body t such as a water supply and drainage pipe or a cable through the passage hole 7.

Therefore, the closing frame 1 according to the present invention can also be used in the through hole a in which a passage body t such as a water supply and drainage pipe or a cable is arranged so that the passage body t such as a water supply and drainage pipe or a cable can pass therethrough. , which has the advantage of expanding its scope of application.

5 and 6 show a fifth embodiment and a sixth embodiment of a closing frame for closing a through hole of a building such as a house, and a method of closing the same, according to the present invention.

That is, a closing frame 1 that closes a through hole of a building such as a house.
is made of a flexible perforated material such as a metal mesh material, and unlike the above embodiment, the cylinder body 2, the bottom part 3, the opening part 4, and the engaging part 5 are formed by cutting along the axis. At this time, when inserting the closing frame 1 into the through hole a, even if the through hole a has various sizes, the closing frame 1 By opening or closing the separation part 8 of 1, the outer diameter of the cylindrical body 2 is changed, and the through hole a is closed with the closing frame 1 following the inner wall of the through hole a. Insert frame 1.

Therefore, the versatility of the closure frame 1 is increased, and the types of closure frames can be minimized.

7 and 8 show a seventh embodiment and an eighth embodiment of a closing frame for closing a through hole in a building such as a house, and a method for closing the same, according to the present invention.

That is, a closing frame 1 that closes a through hole of a building such as a house.
is made of a flexible perforated material such as a metal mesh material, and unlike the above embodiment, the cylinder body 2, the bottom part 3, the opening part 4, and the engaging part 5 are formed by cutting along the axis. Furthermore, the closing frame 1 is formed so as to be divisible by the divided portions 9. The closing frame 1 has a flange 6 upright with the center portion of the bottom portion 3 facing inward of the cylindrical body 2. A passage hole 7 is formed through which the through hole a can pass through, and is also divisible by a dividing portion 9 cut away along the axis. In the pre-work, even if the passing objects t such as water supply and drainage pipes and cables have various sizes, by opening or closing the dividing part 9 of the closing frame 1 more, the passage hole 7 can be used for water supply and drainage pipes and cables. This can be carried out by changing the diameter of the hole such that the passage body t such as the like can pass therethrough, and passing the passage body t through the passage hole 7.

In addition, when inserting the closing frame 1 into the through hole a, the through hole a
Even if the size of the cylindrical body 2 is various, by opening or closing the divided portion 9 of the closing frame 1 more, the outer diameter of the cylindrical body 2 can be adjusted to a diameter that can be inserted into the through hole a. With the outer diameter following the inner wall of the through hole a,
Insert the closing frame 1 into the through hole a.

Therefore, even if the passage body t and the through hole a have various sizes, the passage body t and the closed frame 1 can be inserted by opening or closing the passage hole 7 and the dividing portion 9 more. The outer diameter is made to follow the inner wall of the through hole a, and the hole diameter is made to follow the hole diameter through which the passage object t can pass, and the closing frame 1 is placed in the through hole a. The passage body t can be inserted into the passage hole 7 or can be passed through the passage hole 7.

Therefore, the through-hole a and the passage hole 7 are not limited to a specific diameter, but can be adapted to a predetermined range of diameters above and below the specific diameter, and have great versatility. It can be adapted not only to straight pipes but also to irregularly shaped holes such as tapered ones, and the types of the closing frames can be reduced as much as possible.

The material of the closing frame 1 is not limited to the punched metal or metal mesh material mentioned in the above embodiments, but may be a perforated material with a large number of holes, as well as a material that is suitable for filling the filling material. Any material that has the strength to withstand pressure may be used, and is not limited to metal materials; synthetic resin materials, fibers,
It may be made of paper or other materials, and in addition to having the same effects as the above embodiments, it also has advantages such as lower cost and lighter weight.

Furthermore, the external shape of the closing frame 1 is not limited to the cylindrical shape in the above embodiments, but may be square, elliptical, or elongated depending on the shape of the hole to be closed.
Furthermore, a corresponding external shape such as a tapered cylinder can be used.

As described above, the closing frame according to the present invention makes use of the holes in the perforated material to increase the bonding area between the filler and the through hole (or, conversely, to increase the bonding area between the filler and the through hole). By filling the inside of the closing frame with a filler such as concrete or mortar, the through hole, the closing frame, and the filler can be connected to each other, which dramatically improves the workability of closing. Since the bondability between the through hole, the closing frame, and the filling material can be significantly improved, it can be widely used as a closing frame for closing the through holes of buildings such as houses.

<Effects of the Invention> As described above, according to the present invention, there is provided a closing frame formed in a bottomed cylindrical shape with an opening at one end made of a perforated material such as a metal mesh material provided with a large number of holes, and the closing frame. After inserting into the through hole, the inside of the closing frame is filled with a filler such as concrete or mortar to close the through hole, thereby connecting the filler and the inner wall of the through hole. By using the method of closing through holes in buildings, it is possible to dramatically improve the workability of closing through holes in partition members such as walls and foundations of buildings such as houses, and also to The bondability between the closing frame and the filling material can be significantly improved.

In other words, the pre-work for filling the through hole with filler material is as follows:
This can be done by inserting a closing frame into the through hole, which eliminates the need for the conventional lining work and facilitates the closing work.

In addition, since the closing frame is made of perforated material such as punched metal or metal mesh material, the bonding area between the filling material and the through hole is large (
Conversely, there are fewer unbonded parts between the filler and the through hole.)
By filling the inside of the closing frame with a filler such as concrete or mortar, the bond between the filler and the through hole is excellent, and the bond between the closing frame, these fillers, and the through hole is also excellent. It becomes something.

Furthermore, if the opening end of the cylinder is provided with an engagement piece that engages with the outer edge on the front side of the through hole, the engagement piece can be engaged with the outer edge of the through hole to connect the closing frame. It is possible to engage the hole, and the engagement between the through hole and the closing frame becomes simple and reliable.

In addition, in the case where a passage hole is provided at the bottom of the cylindrical body so that a passage body such as a water supply and drainage pipe or a cable can pass therethrough, the through hole in which the passage body is disposed may also be A closed frame can be used and its range of application can be expanded.

Furthermore, in the case where the through-hole is formed to be separable or divisible by a separation part or a division part formed by cutting along the axial direction, the size of the through-hole may be various sizes. , or even if the size of the passing object such as a water supply/drainage pipe or cable to be inserted into the passing hole is various, when inserting the closing frame into the through hole, or when inserting the passing object into the passing hole. At this time, by opening or closing the separating part or dividing part of the closing frame, the outer diameter of the cylinder can be adjusted to a diameter that allows insertion into the food-friendly hole, or the inner diameter of the passage hole is adjusted to a diameter that allows the passage object to be inserted. It is possible to insert the closing frame into the through hole or insert the passage body into the passage hole by changing the tracking so that the closing frame is changed, so that it is highly versatile and the types of the closing frame can be minimized. If you can do it, the effect is extremely large.
