Description

The present invention relates to a construction method for an interior wall structure of a building frame.

In recent years, in the renovation of toilet spaces in office buildings, schools, etc., dumpling-like mortar is applied to appropriate locations on existing walls, gypsum board that is the wall base material is crimped and fixed, and the mortar is cured until it dries Afterwards, there is an interior wall structure called the GL method in which interior materials are pasted and finished from above. In addition, when the existing wall is a tile, after applying the cationic base preparation before applying the mortar and curing for one day until drying, the work is performed. (See Patent Document 1)

In addition, the interior is called the light iron stud construction method that does not require curing during construction, in which the gypsum board that is the wall base material is screwed to the base consisting of the upper and lower runners and light iron studs, and the interior material is pasted from above. There is a wall structure.

Japanese Examined Patent Publication No. 62-58636

In the interior wall structure called the GL method, the thickness of the gypsum board and dumpling mortar as the base material is 20 to 25 mm, and the interior material of about 6 mm is attached to the double-sided tape and adhesive of about 1 mm from the top of the gypsum board. Therefore, the dimension from the existing wall to the interior material surface of the new interior wall is 27 to 32 mm. Also, even in the case of an interior wall structure called light iron stud construction method, the thickness of the gypsum board and light iron stud as the base material is about 77mm, and the interior material of about 6mm is double sided tape and adhesive of about 1mm from the top. Therefore, the dimension from the existing wall to the interior material surface of the new interior wall is 84 mm or more. In any construction method, the existing toilet is narrowed by the above dimensions.

In renovation of toilet spaces in office buildings, schools, etc., a new interior wall is pasted inside the existing wall, so it is always narrower than before the renovation, so even a little from the existing wall to the interior material surface of the new interior wall There is a need to reduce the dimensions of Accordingly, the present invention has been made to solve the above-described problems, and an object of the present invention is an interior wall structure in which a new interior wall is pasted inside an existing wall to repair a toilet space. An object of the present invention is to provide an interior wall structure in which the thickness of the wall is thinner than the thickness of the interior wall by the conventional method.

In order to achieve the above object, the present invention attaches upper and lower runners to either a wall, a floor, or a ceiling, fixes the upper and lower ends of a vertical frame made of a thin plate so as to be curved to these upper and lower runners, and then has rigidity. The vertical frame is pressed against the adhesive previously applied to the wall surface using the member, the vertical frame is fixed in a straight line, and the interior material is attached to the vertical frame.

In this invention, the vertical frame is fixed to the upper and lower runners and attached to the existing wall surface with an adhesive or the like, so that the thickness of the adhesive or the like is made thinner than the mortar used in the conventional GL method. Can do. In addition, even without using light iron studs like the light iron stud method, the vertical frame has sufficient strength, so by renovating the toilet space by pasting a new interior wall inside the existing wall, The thickness of the new interior wall can be made thinner than the thickness of the interior wall by the conventional method.

The invention according to claim 3 is characterized in that the vertical frame has an L-shaped cross section. If an L-shaped frame is used for the entrance corner or exit corner, the right angle of the exit corner can be accurately obtained, so that the right angle of the entrance corner or exit corner is affected by the unevenness of the existing wall. It is possible to finish with good appearance without deteriorating the fitting with equipment such as a wash-basin counter and urinal lining.

According to a fourth aspect of the present invention, the vertical frame is positioned at a joint portion of the interior material. By doing in this way, since the vertical frame is located at the joint portion of the interior material, it can be applied flush without any step between the interior material and the interior material even without special technology. .

According to a fifth aspect of the present invention, a reinforcing member having a thickness that is flush with the vertical frame is fixed to the existing wall between the vertical frames using an adhesive. For example, it becomes easy to fix accessories such as handrails by using the vertical frame horizontally.

According to the present invention, the vertical frame is fixed to the upper and lower runners and attached to the existing wall surface via an adhesive or the like, so that the thickness of the adhesive or the like is made thinner than the mortar used in the conventional GL method. Even if light iron studs are not used in the light iron stud method, the vertical frame has sufficient strength, so a new interior wall is affixed to the inside of the existing wall to repair the toilet space. The thickness of the conventional interior wall can be reduced. Furthermore, if a space of 7 mm or more is provided on the back side of the upper runner, it is possible to route the electric cable on the back of the wall without putting any cracks on the existing wall, so there is no noise, dust, dust, and the existing wall. The wire cable can be wired while minimizing the dimension from the surface to the interior material surface.

Hereinafter, an embodiment of the present invention will be described in detail with reference to the drawings. FIG. 1A is a longitudinal sectional view of the interior wall structure, and FIG. 1B is a view in which a part of the interior material of the interior wall structure is removed. 1 is an interior wall structure, 2 is an upper runner, 3 is a lower runner, 4 is a vertical frame, 5 is an adhesive, 6 is a double-sided tape, 7 is an interior material, 8 is a baseboard, 9 is a new ceiling finishing material, 10 Is a new floor finishing material, 11 is a new floor base material, 12 is an adhesive for interior materials, 13 is an existing floor, 14 is an existing wall, and 15 is a new ceiling base.

The upper runner 2 is fixed horizontally with an adhesive or the like 5 at an upper position of the existing wall 14. The lower runner 3 is fixed horizontally with an adhesive 5 or the like at a lower position of the existing wall 14. Further, after the adhesive 5 or the like is cured, a new floor base material 11 is poured. The vertical frame 4 is fixed to the upper runner 2 and the lower runner 3 with a double-sided tape 6 and is fixed to an existing wall 14 with an adhesive 5 or the like. The interior material 7 is fixed to the vertical frame 4 by using the interior material adhesive 12 and the double-sided tape 6 together.

Here, in the shape of the upper runner 2 and the lower runner 3, an L-shaped frame is attached in the example of FIG. 1, but the structure is not particularly limited, and when fixed to the wall, a plate-like member But it ’s okay. Further, as shown in FIG. 2, the upper runner 2 and the lower runner 3 are not necessarily one, and two or more may be combined. As shown in FIG. 2, first, the upper runner 2 is fixed to the existing wall 14 with screws, and then the upper runner 2 ′ is fixed with the double-sided tape 6, so that the upper runner 2 can be attached without using the adhesive 5 or the like. Since the curing time for the adhesive 5 or the like can be omitted, the construction period can be greatly shortened. Further, the installation of the upper runner 2 can be adjusted in the height direction, and then the installation of the upper runner 2 ′ can be adjusted in the depth direction, so that workability is improved.

Further, in the example of FIG. 1, the upper runner 2 and the lower runner 3 are fixed to the existing wall 14 with an adhesive 5 or the like. However, when there is an existing ceiling, the upper runner 2 is attached to the existing ceiling (illustrated). However, the lower runner 3 may be fixed to the existing floor 13 with screws or double-sided tape 6 and the fixing method is not particularly limited.

In addition, since the lower runner 3 is embedded in the new floor base material 11 in the example of FIG. 1, even if the lower runner 3 is fixed to the existing floor 13 with screws, the screw head is attached to the new floor base material. 11 can be concealed, and the lower runner 3 can be fixed with sufficient strength. However, the lower runner 3 may be attached to the upper part of the new floor base material 11, and the attachment position is not particularly limited.

Further, as shown in FIG. 3, the upper runner 2 and the lower runner 3 may be vertically mounted on both sides of the existing wall 14, and the right and left runners may be used as left and right runners. Also good.

FIG. 1B shows an example in which an interior material 7 having a width of 900 mm is applied to the vertical frame 4 arranged at an interval of 450 mm. Especially when the interior material is thin, the vicinity of the center may be curved, but the vertical frame 4 is located at the joint portion of the interior material 7 and the central portion of the interior material 7 to prevent the curvature of the interior material near the center. it can. The number of the vertical frames 4 is not limited, and a plurality of vertical frames 4 may be disposed between the vertical frames 4 and 4 located at the joint. On the other hand, as long as the interior material 7 has sufficient strength as a wall surface, the vertical frame 4 may be disposed only at the joint portion of the interior material 7. Further, as shown in the illustrated example, if a dumpling adhesive 5 or the like is applied between the vertical frames 4 and 4 at an appropriate interval, the strength of the wall surface is improved, and the vertical frames 4 and 4 positioned at the above-mentioned seam are improved. The labor for attaching the vertical frame 4 between them can be saved, and the construction period can be further shortened.

In the width dimension of the vertical frame 4, the vertical frame 4 uses a plate material having a width of 100 mm × thickness of 1 mm in the embodiment. However, the vertical frame 4 is located at the joint portion of the interior material 7 and does not have a special technique. There is no particular limitation as long as the joint between the interior material 7 and the interior material 7 can be flush without causing a step.

The length of the vertical frame 4 is not particularly limited as long as the upper and lower ends of the vertical frame 4 are in contact with the upper runner 2 and the lower runner 3. In addition, if the length of the vertical frame 4 is set to the same height as the ceiling height at the factory in advance, the labor for cutting the vertical frame 4 at the site can be saved, so the construction period can be shortened and the waste material can be reduced. Can be less.

As for the thicknesses of the upper runner 2, the lower runner 3 and the vertical frame 4, if a plate material having a thickness of 1 mm is used and the thickness of the adhesive 5 is 1 mm, the dimension of the wall base can be suppressed to 4 mm. The toilet space after renovation can be expanded. In addition, in order to raise the rigidity of each member, a thick member may be used, and in order to make toilet space wider, a thinner member may be used, and it is not specifically limited. As for the material, stainless steel which does not easily rust is preferable, but a galvanized steel plate, aluminum or the like may be used, and is not particularly limited.

In order to securely bond the existing wall 14 and the vertical frame 4, the adhesive 5 or the like is preferably highly viscous so that the shape can be maintained even if it is applied to the surface of the existing wall 14 as a dumpling. There is no particular limitation. Moreover, if quick-drying adhesive etc. 5 are used, since a curing time can be shortened, a construction period can be shortened.

The frame of the existing toilet entrance frame, window frame, door frame, etc. is only about 10-15mm out of the existing wall 14, so in the case of the conventional construction method, the frame circumference must be updated, so the construction period is extended, Although the cost also increases, if the interior wall structure 1 uses a commercially available interior material 7 such as a melamine plate having a thickness of 3 mm for the wall base as in this embodiment, from the existing wall 14 to the interior material 7 surface. Therefore, the work around the frame can be omitted and the construction period can be shortened.

As for the construction method of the interior wall structure 1, as shown in FIG. 4A, first, by using a downward swing or the like, find the most traveled part of each existing wall 14, and use that part as a reference 16. The runner 2 and the lower runner 3 are fixed with an adhesive 5 or the like.

Next, as shown in FIG. 4 (b), an adhesive 5 or the like is applied to the existing wall 14 so as to protrude from the reference 16 at an arbitrary interval in the vertical direction of the vertical frame 4. The vertical frame 4 is fixed to the upper runner 2 and the lower runner 3 with the double-sided tape 6 attached. In this state, since the vertical frame 4 is curved while the vertical frame 4 is only fixed to the upper runner 2 and the lower runner 3 by the double-sided tape 6, the member 17 having rigidity such as a light iron stud is attached. The vertical frame 4 is straightened by pressing. Also, if the operator presses the rigid member 17 too much and the vertical frame 4 is recessed from the reference 16, the vertical frame 4 can be pulled back and corrected easily. As described above, the vertical frame 4 is fixed to the upper runner 2 and the lower runner 3 with the double-sided tape 6, thereby preventing the vertical frame 4 from peeling off until the adhesive or the like 5 is cured. If the existing wall 14 and the surface of the interior material 7 are large and the amount of the adhesive 5 or the like is large, if a plywood or the like is inserted as a spacer (not shown) between the existing wall 14 and the vertical frame 4, the adhesive The amount of coating 5 can be suppressed.

After the adhesive 5 is cured, the interior material adhesive 12 is applied to the vertical frame 4 as shown in FIG. 1, the double-sided tape 6 is applied, and the adhesive 5 is applied to the existing wall 14 between the vertical frames 4 and 4. Applying at a proper interval in a dumpling form, the interior material 7 is fixed. If there is no existing ceiling, after the interior material adhesive 12 is cured, a new ceiling foundation 15 is applied, a new ceiling finish material 9 is attached, and finally the new floor finish material 10 is pasted with the interior material adhesive 12. For example, the interior wall structure 1 as shown in FIG. Further, when there is an existing ceiling (not shown), after the interior material adhesive 12 is cured, the new ceiling finish material 9 is mounted on the existing ceiling surface, and finally the interior floor material adhesive 12 is used to install the new floor finish material 10. Paste.

A reinforcing member 19 is put in advance on the wall surface to which the accessory is fixed as shown in FIG. In the illustrated example, the reinforcing member 19 is fixed to the existing wall 14 with an adhesive 5 or the like by using the vertical frame 4 sideways. Since the reinforcing member 19 must be constructed so as to be flush with the longitudinal frame 4 that has been constructed in advance, a galvanized steel sheet having a thickness of 1 mm similar to that of the longitudinal frame 4 and capable of sufficiently retaining accessories is preferable. As for the construction procedure, the upper and lower runners 2 and 3 are constructed according to the procedure of FIG. 4, the vertical frame 4 is attached, and then the reinforcement member 19 is constructed with the left and right vertical frames 4 as a reference. Is good. The reinforcing member 19 may increase the vertical frame 4 by one as shown in FIG. 6B without using the vertical frame 4 sideways. Further, as shown in FIG. 6C, if the reinforcing member 19 and the vertical frame 4 are fixed by the double-sided tape 6 used for bonding the vertical frame 4 and the interior material 7 after the reinforcing member 19 is installed, the vertical frame 4 The reinforcing member 19 is easy to be flush with each other, and the reinforcing member 19 can be fixed by using the adhesive 5 and the double-sided tape 6 together, so that the reinforcing member 19 is sufficiently supported and the reinforcing member 19 falls during curing. There is no.

FIGS. 7A and 7B are cross-sectional views showing the interior wall structure when the lower runner also serves as a baseboard. If the lower runner 3 has a structure as shown in FIGS. 7A and 7B, the base runner 8 can also be used, so the number of members can be omitted, and the step of pasting the baseboard 8 can be omitted. Therefore, the construction period can be shortened. The material of the lower runner 3 is preferably stainless steel with a hairline finish, and may be aluminum, and is not particularly limited.

FIG. 8 is a cross-sectional view in plan view showing the interior wall structure at the corner of the toilet space. In the shape of the vertical frame 4, the vertical frame 4 may include an L shape in a plate shape, and may have the L shape in cross section shown in FIG. 8. If this frame is used, the right angle of the protruding corner can be accurately obtained. Therefore, under the influence of the unevenness of the existing wall 14, it finishes with good appearance without deteriorating the fitting with the equipment such as a wash-basin and urinal lining due to the right angle of the entrance corner or exit corner not coming out. be able to.

FIG. 9 is a diagram showing an interior wall structure in which a foaming agent is inserted between an adhesive and the like. 20 is a foaming agent. If fast-curing adhesive 5 or the like is used, adhesive 5 or the like is cured until the upper and lower runners 2 and 3 and the vertical frame 4 do not move by overnight curing, so the upper and lower runners 2 and 3 and the vertical frame 4 were constructed. The interior material 7 can be constructed on the next day. As shown in FIG. 9, by inserting a foaming agent 20 such as a two-component urethane foam between the adhesive etc. 5 and the adhesive etc. 5, the upper and lower runners 2, 3 and the vertical frame 4 take about 10 minutes to complete the interior material 7. Therefore, it is possible to set the wall foundation process and the wall finishing process on the same day, and further shorten the construction period.
