Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an opening closing member, which can be cut along a cutting line very easily on site to improve the simplicity and speed of work with one-touch operation. The present invention relates to an opening portion closing member capable of quickly closing the opening portion by appropriately responding to the difference in size. Further, the present invention relates to an opening closing member which has improved noncombustibility by adopting a plate material made of a special noncombustible material for the opening closing member substrate.

[0002]

2. Description of the Related Art Conventionally, as shown in FIG. 7, a building such as a building has a floor slab S provided through a metal structural material M, and a pipe P for water and sewerage, electricity, gas, etc. However, since the size of the pipe P is not constant, the floor slab S is formed with a pipe hole H larger than the pipe P. The opening portion C between the H and the floor slab S is closed by 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. There is one in which the opening C on the upper surface of the closing plate N is filled with the closing material B.

Further, a release paper is a sheet which is stuck across a pipe inserted into a through hole of a building and a peripheral portion of the through hole, and which is a two-divided adhesive sheet in which an adhesive layer is provided on a sheet or a film-like supporting member. Conventionally, there is a sheet for holding a sealing material having through-holes (see Japanese Patent Application Laid-Open No. 61-130688).

[0005]

However, in the prior art shown in FIG. 7, the work of fixing the closing plate N through the joining members such as nails at the construction site requires a bad footing and an unreasonable posture. Due to the work, there is a problem that the work is not easy and quick and the construction cost is high.

Further, the problem of the prior art disclosed in Japanese Patent Laid-Open No. 61-130688 is that since it is divided into two sheets, the first half is bonded and blocked first, and the other half is bonded first. There is a problem in that it is very difficult to perform the adhesive closing work in a place where the scaffolding is bad while matching the opening closing member.

Furthermore, since the non-combustible material is not used, it is necessary to remove the opening closing member after the work is completed, and the size of the pipe P is not constant.
It is necessary to prepare various kinds of size of the closing plate N corresponding to the size of the pipe and select the closing plate N of the size corresponding to the size of the pipe P each time, which is not only complicated work. However, there is a problem that the parts management becomes complicated and the product cost increases.

In view of such circumstances, the present invention uses a scale and a cutting line so that a tape-shaped opening closing member is wound around a core tube in a roll shape and is drawn out to match a working part on the site. On the other hand, cut into rectangles, triangles, or trapezoids with cutters, scissors, etc., and use a plurality of them properly combined to fold the pipe part according to the corresponding pipe diameter, set it horizontally and fix it. In addition, by using a non-combustible material that has passed the standards in accordance with the Building Standards Act, the structure is simple, and the opening between the floor slab and the pipe can be closed easily and reliably. Product cost and construction cost can be improved by improving the ease and speed of work, and by being able to handle a wide range of pipe sizes without worrying about the size of the closing plate. It is an object of the present invention to provide a simple non-combustible opening closing member for site construction, which can be lowered and construction cost can be reduced.

[0009]

A plurality of rows of substantially square cutting lines are formed in the longitudinal direction by printing lines, streak lines, engraving lines, and ruled lines on the opposite surface, and the lines connecting the diagonals of each substantially square shape are formed in an intersecting shape. A technical means was adopted in which a floor slab made of a flat plate material in which a circular line was formed concentrically with each intersection point formed by the lines and a blocking material such as mortar for blocking the openings of the pipes could be carried.

According to the second aspect of the present invention, a polyester non-woven fabric-coated rock wool felt or rock wool felt mixed with pulp containing 1 to 3% by weight of a water repellent agent and an aluminum foil are bonded with a two-component acrylic adhesive. Adhesive is applied to one surface of the tape-shaped opening closing member substrate having an appropriate width formed by the plate material, the release paper is joined to the adhesive surface, and the surface of the release paper opposite to the side in contact with the adhesive surface is attached. A plurality of rows of substantially square cutting lines are formed in the longitudinal direction by printing lines, streak lines, engraving lines, and ruled lines, and the lines connecting the diagonal lines of each substantially square shape are formed in an intersecting shape, and formed by these lines. The technical means of being able to carry a closing material such as mortar for closing the opening between the floor slab and the pipe, which is made of a flat plate material in which circular lines are formed concentrically with each intersection, is adopted.

In particular, in the case of blocking with a plurality of sheets, the pipe P and the bottom surface of the floor slab S (or the metal structural material M disposed on the bottom surface of the floor slab) which are partially overlapped and fixed and are disposed in the piping hole H of the floor slab S. By adopting a specific structure capable of conforming and adhering to, the openings of the floor slab (and the metal structural material) and the pipe can be easily and reliably closed.

That is, the opening closing member is cut and formed so that it can be fitted to the pipes P of various sizes at the site matching. First, the opening blocking member of each shape cut at the site matching is used and peeled off. After the paper is picked and peeled off to expose the adhesive application surface of the opening closing member, the adhesive application surface of each cut and formed opening closing member is respectively cut into the outer shape of the pipe P and the floor slab S (or the floor slab bottom surface). The bottom surface of the metal structural material M) disposed on the base plate, and is bonded via an adhesive.
Furthermore, it is possible to successively use other opening blocking members of each shape cut at the site matching so as to be fixed so as to overlap with each other and to be fitted to the pipe P and the floor slab S, respectively, and there is a gap or space between them. Since a plurality of sheets are used to close the opening so as not to generate a portion, it is easy to fill the occluding material B such as mortar in the next step.
