Description

  The present invention relates to a formwork material for closing a gap in a horizontal pipe with respect to a wall for closing a gap generated when a pipe is inserted into a through hole for a horizontal pipe installed on a wall such as a fire wall. Cutting with a cutter, scissors, etc. can improve the simplicity and speed of operations with a single touch, and can close gaps quickly in response to differences in pipe size. The present invention relates to a formwork material that closes a gap of a horizontal pipe with respect to a wall that is intended to improve nonflammability by employing a plate-like material made of a noncombustible material.

Conventionally, as shown in FIG. 7, a building such as a building is provided with a pipe P for water and sewage, electricity, gas, etc. on a floor slab S provided via a metal structure M. Since the size of the pipe P is not constant, a pipe hole H larger than the pipe P is formed in the floor slab S. After the pipe P is disposed in the pipe hole H, the pipe hole H and the floor slab S The opening C was closed with a closing material B such as mortar.
When the opening C is closed by the closing material B, a flat closing plate N carrying the closing material B is fixed to the bottom surface of the floor slab S via a joining member such as a nail, and then the closing plate There is one in which the opening C on the upper surface of N is filled with the closing material B.
Moreover, it is a sheet to be bonded across a pipe inserted into a through-hole of a building and a peripheral portion of the through-hole, and a release paper is temporarily attached to a two-part adhesive sheet provided with an adhesive layer on the sheet or a film-like support member Conventionally, there is a sheet for holding a sealing material for a through hole (see, for example, Patent Document 1).
Japanese Patent Laid-Open No. 61-130688 (refer to the claims section, detailed description section and drawings)

  However, in the prior art shown in FIG. 7, the work of fixing the closing plate N via a joining member such as a nail at the construction site is because the work is in a poor position or an unreasonable posture. There were problems of lack of ease and speed and high construction costs.

  Further, since the problem of the prior art disclosed in Japanese Patent Application Laid-Open No. 61-130688 is divided into two sheets, the opening is closed first by half first, and the other half first. There is a problem that it is very difficult to perform the adhesive blockage work in a place where the scaffold is poor while matching with the member.

  Furthermore, since the non-combustible material is not used, it is necessary to always remove the opening blocking member after the work is completed, and since the size of the pipe P is not constant, there are many types that match the size of the pipe P. It is necessary to prepare a block plate N of a size, and to select a block plate N having a size suitable for the size of the pipe P each time. There was a problem that the cost increased.

  In view of such circumstances, the present invention cuts radially 3 to the hole diameter position with a cutter, scissors, etc. as shown in FIG. 2, cuts the lower cut 4, and pipes according to the corresponding pipe diameter. Fold the part corresponding to the part, and set it to the pipe and wall with an adhesive and fix it. In addition, by forming with a non-combustible material that has passed the standard in accordance with the Building Standard Law, the structure is simple, and the construction for closing the opening with the horizontal pipe to the wall can be performed easily and reliably. Ease of operation and quickness can be improved, and it is possible to handle a wide range of pipe sizes without worrying about the size of the blocking plate. An object of the present invention is to provide a formwork material that closes a gap between horizontal pipes with respect to a non-combustible wall that is easy to match on site and that can reduce construction costs.

A first device of the present invention for solving the above-mentioned problems is a formwork material for closing a gap of a horizontal pipe with respect to a wall as described in claim 1, and is as follows.
In consideration of the hole diameter, an adhesive is applied to one entire surface of the opening blocking member substrate made of a non-combustible material formed in a substantially square shape, and a release paper is bonded to the adhesive surface, and the adhesive surface of the release paper Hexagonal to decagonal corners from the center point so that a hexagonal to decagonal folded opening is formed in the central part of this substantially square shape by printed lines, streaks, engraved lines, and ruled lines on the substrate surface opposite to the contact side. In this configuration, lines are formed so as to be cut at the respective lines.

A second device of the present invention for solving the above-mentioned problem is a formwork material for closing a gap of a horizontal pipe with respect to a wall as described in claim 2, and is as follows.
In addition to the invention described in claim 1, a glass fiber felt or a ceramic fiber felt incombustible material is employed as the material of the opening closing member substrate.

A third device of the present invention for solving the above-mentioned problem is a formwork material for closing a gap of a horizontal pipe with respect to a wall as described in claim 3, and is as follows.
In addition to the device described in claim 1 or 2, the aluminum foil is attached to the surface opposite to the release paper bonded to one surface of the opening portion closing member substrate via an adhesive.

Since the formwork which closes the gap of the horizontal pipe with respect to the wall according to the present invention has the configuration as described above, the following effects can be obtained.
(1) It can be easily adjusted on site, and can be closed easily and quickly by fitting the gap between the wall and the horizontal pipe to improve the speed and reliability during construction. Construction costs can be reduced.
(2) Since it is made of non-combustible material, there is no need to remove the formwork material after closing the opening of the formwork material that closes the gap between the horizontal pipes against the wall, reducing the speed and construction cost during construction. be able to.
(3) The formwork material that closes the gap between the horizontal pipes with respect to the wall is formed into a square plate shape, a rectangular plate shape, a triangular plate shape, a trapezoidal plate shape, a circular plate shape, etc. Since the thing cut into the shape necessary to close the entire gap with the pipe is formed on the site, it becomes easy to fit the pipe and the wall to adhere to both, etc. There is an advantage that the construction is easy and quick. In particular, the work is generally complicated and dangerous, and the on-site work that is dangerous becomes easy and quick, so the effect is great.
(4) Since the formwork material that closes the gap between the horizontal pipe and the wall can be easily bonded to the pipe and the wall, the bonding between the pipe and the wall is ensured, and the opening between the pipe and the wall is made of rock wool, etc. It can be securely closed by supporting the plugging material, and even in the event of an unexpected situation such as a fire or an earthquake, a formwork that closes the gap between the horizontal pipes together with the plugging material such as rock wool on the wall can cause a fire or earthquake. There is an advantage that an unexpected situation can be surely prevented.

  In consideration of the hole diameter, an adhesive is applied to one entire surface of the opening blocking member substrate made of a non-combustible material formed in a substantially square shape, and a release paper is bonded to the adhesive surface, and the adhesive surface of the release paper Hexagonal to decagonal corners from the center point so that a hexagonal to decagonal folded opening is formed in the central part of this substantially square shape by printed lines, streaks, engraved lines, and ruled lines on the substrate surface opposite to the contact side.
