Description

TECHNICAL FIELD The present invention relates to a wall construction method for forming inner and outer walls and a ceiling wall of a building.

(Prior art) As a wall construction method for forming the inner and outer walls and ceiling walls of a building,
A plaster coating method is generally used in which a large number of baseboards such as gypsum boards are arranged to form a base with a seam, and then a plaster layer is applied to the surface of the base to form a plasterboard. Since it cannot be completely hidden, seams appear even after finishing the surface due to the oblique rays from the sun or illuminating lights, which is annoying. For this reason, conventionally, the seams are hidden by putty or joint tape and then plastered, but these operations are troublesome and require the work of a skilled craftsman, which is costly in the present situation where manpower is insufficient.

In order to solve such a defect, a wall construction method is also known in which a net is adhered to the surface of the base, plaster or putty is applied on the entire surface, and then surface finishing is performed.
Although it has already been proposed by Japanese Patent Publication No. 290864, there is still a problem that it is troublesome to work because it is difficult to attach the net without wrinkling. Further, in JP-A-55-2501,
When sticking the net on the entire surface of the base, apply an adhesive to the entire surface of the base and press down the wrinkles with a trowel etc. from the drawn end of the net roll wound in a roll shape. Although there is a description about the technique of sticking without wrinkling by going to the wrinkle, on the wall or ceiling surface where the adhesive has been applied, when the feet are unstable such as a stepladder, a fine net is wrinkled with a trowel etc. It is almost impossible to hold down and push down.

(Problems to be Solved by the Invention) The problem to be solved by the present invention is to solve the above-mentioned problems, to completely hide the seams and scratches between base boards and to make the feet unstable. The object of the present invention is to provide a wall surface construction method which can be easily constructed without the need of a skilled craftsman even in such a state, has a good finish, and has low cost, which increases durability.

(Means for Solving the Problem) The wall surface construction method of the present invention which is intended to solve the above-mentioned problem is such that the net coated with the adhesive on one side of the fine mesh net is the outside with the adhesive coated surface. Roll the rewritable net roll along the surface of the base with seams and scratches, stick the net on the entire surface of the base, and then apply plaster or putty over it It is characterized by finishing.

The base in the present invention is usually a base with a joint formed by arranging a number of flat plate-like baseboards such as a gypsum flat board, but it is already used after a long period of time and partial peeling of the paint is seen. It may be a wall surface, and in the case of a base with a joint formed by arranging a large number of baseboards as described above, the type of baseboard to be used and the arrangement method thereof are also arbitrary, but in any case However, before applying plaster coating or putty coating to the base with seams or scratches that make up the ceiling or wall surface, rewind the fine mesh net cloth coated with adhesive on only one side with the adhesive as the outside. A feature of the present invention is that a net roll, which is wound in a roll shape, is rolled along with the base as much as possible so that the net is entirely attached to the surface of the base. Inorganic fiber yarns such as thick glass long fibers having fire resistance are generally used as the yarns for knitting the net fabric, but long glass fibers are twisted with chemical fiber yarns for reinforcement such as polyester fibers. Fibers other than inorganic fiber threads such as thread may be used. Also, if the mesh is too large, the adhesiveness of the plaster layer or putty layer is poor and the performance of hiding seams and scars is also poor. It is necessary to keep the mesh fine. In addition, as the net to be used, one side of the net cloth is coated with an adhesive and is wound in a roll shape with the adhesive coated surface as the outside without intervening release paper, and this net roll is rolled to form a base. It is especially important to stick the net all over the surface for efficient construction.In this case, an adhesive or fiber is used so that it can be rewound even if it is wound in a roll without intervening release paper. It is necessary to select the type of, and in this respect, an acrylic resin and a synthetic rubber are provided on one side of a net fabric formed by weaving inorganic fiber yarns, which are lightly twisted together with glass long fibers as described in the examples below, as wefts and warps. Those coated with a pressure-sensitive adhesive as the main material are particularly preferable. Also, the plaster coating or putty coating work after the net is completely attached to the base surface may be the conventional plaster coating method or putty coating method, but after performing the plaster coating or putty coating, Must be surface finished. As this surface finish, if the plaster layer or putty layer formed by plaster coating or putty coating is a thick layer of several millimeters or more, it is sufficient to trowel finish the surface, but a layer for spraying decorative particles or a paint layer, etc. May be layered or wallpaper may be attached.

In this way, before applying plaster coating or putty coating on the surface of the base with seams or scratches, if you stick an adhesive net coated with adhesive on a fine mesh net to the entire surface of the base By plaster coating or putty coating, plaster or putty first fills each mesh and is divided by threads to form a root integrated with the base surface and the thread, and then a plaster layer or putty layer is formed on the basis of the roots described above. Even if the base is flat, the adhesive force between the plaster layer or putty layer and the base is large, and the seams and scratches between the bases must be covered with putty or joint tape beforehand. Also, no seams or scratches appear on the surface of the plaster layer, and after finishing the surface, the seams and scratches will not be visible even if the sun or the oblique rays from the lighting lamp are received Ritonaru It will be completely eliminated. In addition, since the net material having a fine mesh attached to the entire surface of the base reinforces the whole, fire resistance and durability are remarkably improved.

(Example) Example 1 As shown in FIG. 1, 180 cm × 9 as a base board (1)
A base (3) having a seam (2) formed by arranging a large number of 0 cm × 9 mm plaster flat boards vertically and horizontally was constructed on the ceiling surface by a conventional method. Next, an acrylic resin and a synthetic rubber were attached to one side of a net fabric of 90 cm width and 60 m, which was knitted so that a mesh of 2 mm square was formed by using inorganic fiber yarns in which two long glass fibers were lightly twisted together as wefts and warps. Adhesive net coated with pressure-sensitive type pressure sensitive adhesive (4)
Apply the net roll wound in a roll shape so that the coated surface of the adhesive is on the outside of the base (3), lightly press the pull-out end against the surface of the base (3) and roll it while holding the adhesive. Base board (1),
The net (4) is completely attached to the surface of the base (3) so that the seam (2) between (1) and the net seam do not match, and then plaster plaster material is troweled to a thickness of 6 mm. Was formed into a uniform plaster layer (5), and finally, a surface coating layer (6) was formed by spray coating of a covering material in which decorative fine particles such as vermiculite were mixed.

The ceiling thus obtained does not appear in the plaster layer (5) even if the joint (2) is not covered with putty or joint tape in advance, and after finishing the surface. In the above, the seam (2) did not hinder the eyes even if it receives an oblique ray from the sun or an illumination lamp. Moreover, the net (4) with fine meshes, which is entirely attached to the surface of the base (3), also hides the scratches and dents on the surface of the base (3), and a uniform surface finish was obtained. Furthermore, a net roll having a net (4) coated with an adhesive on one side of the net fabric and which can be unwound so that the surface coated with the adhesive is the outside can be rolled by gently pressing the pull-out end against the surface of the base (3). The net can be attached to all surfaces of the base (3) with seams and scars easily and accurately without wrinkling, so even if you are standing on a stepladder such as the ceiling surface or wall surface, you will not be able to work on it. No problem,
The time required for a series of operations is less than one-third that of the conventional method, and work efficiency is significantly improved, enabling cost reduction.

Example 2 The net roll used in Example 1 was directly applied to the existing concrete inner wall surface that was used as a base for a long time and in which partial peeling of the paint was observed, and the drawer end was lightly pressed against the surface of the base while rolling. A net was attached to the entire surface of the base with the adhesive, and then a putty material was troweled to form a uniform putty layer having a thickness of 1 mm, and finally a wallpaper was attached to finish the surface.

The inner wall obtained in this way had no unevenness or wrinkles on the exterior wallpaper even though the partially peeled paint layer was not peeled off, and it had a beautiful finish that could not be considered a reformed wall. Was obtained. In addition, there is no problem in work even if the feet are unstable when standing on a stepladder such as the ceiling surface or wall surface, the time required for this work is 1/3 or less of the conventional method, and work efficiency is significantly improved. Cost reduction has become possible.

(Effects of the Invention) As is apparent from the above description, the present invention, before applying plaster coating or putty coating to the base of the ceiling wall or the inner and outer walls,
A net with adhesive coated on only one side can be unwound so that the coated side of the adhesive is the outside.Roll it while applying it to the surface of the base with seams or scratches, and roll the net onto the entire surface of the base. Since it was put on, the seams between the base boards forming the base and the scratches on the surface of the base can be completely hidden by the plaster layer or putty layer, giving an excellent surface finish and peeling. It also has excellent strength, and there is no problem in work even if the feet are unstable when standing on a stepladder such as the ceiling surface or wall surface. Even in such a case, since there is no need for a skilled craftsman to perform the construction easily, there are various advantages such as low cost and efficient work, and increased durability.

Therefore, the present invention has a very large contribution to the development of the industry as a wall construction method that solves the problems of the conventional wall construction method.
