Description

  TECHNICAL FIELD The present invention relates to a method for repairing a room or the like in a building and a repair wall structure.

  When removing a partition wall provided in a room of a building and renovating the room, in general, the height of the ceiling surface of the two spaces separated by the partition wall may be different, and in this case, There is a problem that a flat ceiling surface is not formed. Therefore, as described in Patent Literature 1, for example, after removing the partition wall, a gap closing member is attached to a portion where the partition wall has been removed, and the existing vinyl cloth is peeled off from the ceiling, and a new vinyl cloth is removed. A method of gluing so as to cover a ceiling and a gap closing member is known.

  However, in the method described in Patent Document 1, it is necessary to insert a connecting member into the space above the ceiling from the gap formed by removing the partition wall and connect the two ceilings separated by the connecting member, A lot of trouble is required, for example, it is necessary to provide a gap closing member for closing the space.

  On the other hand, as described in Patent Literature 2, for example, as a method of easily performing the work at the time of repair, a crosspiece and a surrounding edge are provided in advance in a gap between the upper end portion of the partition wall and the ceiling surface at the time of new construction. In addition, there is known a method of removing the partition wall while leaving the crosspieces and the periphery at the time of repair. In this repair method, after removing the partition wall, the exposed surface of the remaining crosspiece is dressed with a decorative material.

  In the repair method described in Patent Literature 2, the exposed surface of the crosspiece left at the time of removal of a wall such as a partition wall is dressed with a decorative material, but reattachment of the ceiling cloth is not assumed in the first place. However, only new cosmetic materials stand out from the existing ceiling cloth, and it is hard to say that the ceiling surface looks good.

  Therefore, an object of the present invention is to provide a repair method and a repair wall structure that can easily realize a repair work involving removal of a wall body and improve the appearance after the repair.

  In order to solve the above-mentioned problem, the present invention relates to a repair method for removing a part of a wall provided between a first space and a second space in a building, the method comprising: Removing the lower part of the wall body while leaving the lower part, and after the step of removing the lower part, the ceiling surface of the first space, the surface of the upper part on the first space side, and the lower end surface of the upper part And covering with a new finishing material.

  In the repair method according to the present invention, the lower part of the wall provided between the two spaces is removed without any modification to the base material of the ceiling, etc. Two spaces can be integrated. Further, since the upper portion of the wall body is left, even if there is a step between the ceiling surfaces of the two spaces, it can be made inconspicuous. In addition to this, the ceiling surface of the first space, the surface on the first space side of the upper part of the wall, and the lower end surface of the upper part of the wall are all covered with a new finishing material. The upper part of the wall is assimilated with the ceiling surface of the first space to give a sense of unity. As described above, the repair work involving removal of the wall can be easily realized, and the appearance after the repair can be improved.

  In the renovation method according to the present invention, the first space is a kitchen space, the second space is a dining space, and in the step of covering with a new finishing material, the ceiling surface of the dining space is an existing space. The state covered with the finishing material may be maintained. In this case, since the ceiling surface of the kitchen space, which is generally smaller than the dining space, is repaired, the repair work is reduced. Further, only the kitchen space to which oil stains and the like are likely to adhere due to cooking or the like is renovated with a new finishing material, and the dining space is left as it is.

  In the refining method according to the present invention, in the step of covering with a new finishing material, at least a part of the surface of the upper space on the second space side is further covered with the new finishing material, and the step of covering with the new finishing material is performed. Thereafter, a step of providing a parting material covering the end of the finishing material between the upper portion and the second space may be further included. In this case, since the end of the new finishing material is covered with the parting material, the fitting is improved, and the appearance can be further improved.

  In the repair method according to the present invention, the wall may be a descending wall. In this case, since the object to be removed at the time of renovation is a falling wall, the work of removing the lower part becomes easy. Further, when the wall is a descending wall, the wall is originally firmly held by the ceiling. Therefore, even if the lower part of the falling wall is removed, the upper part of the remaining falling wall can be structurally maintained.

  In the repair method according to the present invention, the hanging storage is fixed to the first space side of the falling wall, and in the step of removing the lower part, the hanging storage may be removed together with the lower part. In this case, by removing the hanging storage together with the lower part, the kitchen space and the dining space can be integrated with a small amount of repair work. Furthermore, since the falling wall to which the hanging storage is fixed is more firmly held on the ceiling side so as to receive the load of the hanging storage, even if the lower part of the falling wall is removed, the remaining falling wall remains. Can be reliably maintained structurally.

  Further, in the renovation method according to the present invention, the building includes: an upper end base material serving as a base material on the upper end side of the wall body; and a ceiling base material serving as a base material of each ceiling in the first space and the second space. Provided, the upper substrate is a winning arrangement with respect to the ceiling substrate, the lower surface of the upper substrate is located below each ceiling surface of the first space and the second space, and the upper surface of the upper substrate is The first space side and the first end of the ceiling base on the second space side are located above the lower surfaces of the respective ceiling bases on the first space side and the second space side. The second end is connected to the upper end substrate, and the upper end substrate may be left in the step of removing the lower portion. In this case, even after the lower part is removed, the state in which the ends of the respective ceiling foundations on the first space side and the second space side are connected to each other by the upper end foundation is maintained. The end of the lens does not hang down, and the appearance can be improved.

  Further, the present invention is a renovation wall structure provided between a first space and a second space in a building, the renovation wall structure being lower than a ceiling surface of the first space and a ceiling surface of the second space. The upper wall portion has a first space-side surface, a second space-side surface, and a lower end surface. The space and the second space communicate with each other, and the ceiling surface of the first space, the surface of the upper wall on the first space side, and the lower end surface of the upper wall are the ceiling of the second space. It is covered by a new finish that is newer than the surface covering.

  This rehabilitation wall structure can be realized by the rehabilitation method described above, and is a result of easily realizing the rehabilitation work involving removal of the wall. In this modified wall structure, the first space and the second space communicate with each other below the lower end surface of the upper wall portion. That is, the first space and the second space are integrated with the upper wall as a boundary. Since the upper wall projects below the ceiling surface of the first space and the ceiling surface of the second space, it should not be noticeable even if there is a step between the ceiling surfaces of the two spaces. Can be. In addition to this, the ceiling surface of the first space, the surface of the upper wall on the first space side, and the lower end surface of the upper wall are all covered with a new finishing material. The part can be assimilated with the ceiling surface of the first space to give a sense of unity to the appearance. Therefore, the appearance after the repair can be improved.

FIG. 2 is a cross-sectional view of the descending wall 10 of FIG. 1 along the line II-II. FIG. 3 is a cross-sectional view showing the falling wall 10 of FIG. 2 in an enlarged manner. 2 and 3, the base material of the ceiling 2 in the building 100 is shown in addition to the falling wall 10. 2 and 3, illustration of the hanging storage 3 is omitted.

  As shown in FIGS. 1 to 3, the repair method according to the present embodiment removes a part of a descending wall 10 (wall body) provided between a kitchen space R1 and a dining space R2 in a building 100, for example. It is a renovation method. The kitchen space R1 is a first space on one side of the falling wall 10, and the dining space R2 is a second space on the other side of the falling wall 10. The repair method according to the present embodiment is used for integrating the kitchen space R1 and the dining space R2, which are spaces on both sides of the falling wall 10.

  The building 100 includes a kitchen space R1 and a dining space R2, and a falling wall 10 is formed between the kitchen space R1 and the dining space R2. The falling wall 10 projects below the ceiling 2 of each of the kitchen space R1 and the dining space R2. The falling wall 10 is separated from the floor. For example, the falling wall 10 hangs a predetermined distance (for example, about 60 to 80 cm) from the ceiling 2 having a lower height position among the ceiling 2 of the kitchen space R1 and the ceiling 2 of the dining space R2. . On the kitchen space R1 side of the falling wall 10, a hanging storage 3 and the like are fixed.

  As shown in FIG. 2, the building 100 includes a beam 5, a ridge receiver 6 held on the beam 5 via a hanging hardware 14, and a ridge 7 (ceiling base) fixed to the ridge receiver 6. And a gypsum board 9 fixed to the bezel 7 with screws or the like. The ridge 7 is a base material for the ceiling 2 of each of the kitchen space R1 and the dining space R2. The gypsum board 9 is fixed to the edge 7 on the kitchen space R1 side and the edge 7 on the dining space R2 side, respectively. Thereby, the ceiling 2 of the kitchen space R1 and the ceiling 2 of the dining space R2 are formed.

  The ceiling 2 of the kitchen space R1 has a ceiling surface 2a facing the interior of the kitchen space R1, and the ceiling 2 of the dining space R2 has a ceiling surface 2b facing the interior of the dining space R2. The height position of the ceiling surface 2a of the kitchen space R1 and the ceiling surface 2a of the dining space R2 may be the same as illustrated, or may be different from each other. That is, there may be a step between the ceiling surface 2a of the kitchen space R1 and the ceiling surface 2b of the dining space R2. For example, due to the original design, the ceiling surface 2a of the kitchen space R1 may be lower than the ceiling surface 2b of the dining space R2 by about 10 cm. Although the heights of the ceiling surface 2a and the ceiling surface 2b are set to be the same in design, the ceiling surface 2a may be higher than the ceiling surface 2b by about 3 mm due to a construction error or the like.

  Further, the building 100 includes wall bases 11, 12 provided between the kitchen space R1 and the dining space R2, and a plurality of gypsum boards 13 fixed to the wall bases 11, 12 with screws or the like. I have.

Hereinafter, after the modification by the modification method according to the embodiment is simply referred to as “after modification”, and before modification by the modification method according to the embodiment is simply referred to as “before modification”.

  As shown in FIGS. 4 to 6, the building 1 after the renovation includes a kitchen space R1 and a dining space R2 as in the building 100 before the renovation. On the other hand, in the building 1 after the renovation, the lower part 10e of the falling wall 10 located between the kitchen space R1 and the dining space R2 in the building 100 before the renovation has been removed. 10d remains. In the building 1 after the repair, the hanging storage 3 and the like fixed to the kitchen space R1 side of the falling wall 10 in the building 100 before the repair are removed. In the building 1 after the repair, a repair wall structure 1a (see FIG. 6) is provided between the kitchen space R1 and the dining space R2.

  As shown in FIG. 5, the building 1 after the renovation includes a beam 5, a ridge receiver 6, a ridge 7, and a gypsum board 9, similarly to the building 100 before the renovation. The renovation wall structure 1a includes an upper portion 10d (upper wall portion) of the descending wall 10, a new wall foundation 33, and a new gypsum board 34.

  The upper portion 10d of the falling wall 10 is a remaining portion of the falling wall 10 remaining after the repair (see FIG. 8A). The upper part 10d of the falling wall 10 is fixed to the ceiling 2 of the kitchen space R1 and the dining space R2. The upper part 10d of the falling wall 10 protrudes below the ceiling surface 2a of the kitchen space R1 and the ceiling surface 2b of the dining space R2. An upper portion 10d of the descending wall 10 includes a wall base 11, a side wall 13a, and a side wall 13b. The side wall portion 13a is an upper portion of the gypsum board 13 attached to the surfaces 11c and 12c of the wall bases 11 and 12 on the kitchen space R1 side before the repair. The side wall portion 13b is an upper portion of the gypsum board 13 attached to the surfaces 11d and 12d of the wall bases 11 and 12 on the dining space R2 side before the repair.

  The wall base 33 is a base material for providing the gypsum board 34 on the lower end side of the upper part 10 d of the falling wall 10. The wall base 33 is fixed to the wall base 11 with, for example, a screw or the like, and is located on the lower side facing the wall base 11. The wall base 33 is located between the side wall 13a and the side wall 13b. An adhesive or the like may be applied between the wall base 33 and each of the side walls 13a and 13b. A gypsum board 34 is fixed to the lower end surface 33a of the wall base 33 with screws or an adhesive so as to be located between the side wall portions 13a and 13b. Thereby, the ceiling 4 is formed between the kitchen space R1 and the dining space R2.

  The ceiling surface 4a of the ceiling 4 is located a predetermined distance (for example, about 4 to 6 cm) below the ceiling surface 2a of the kitchen space R1 and the ceiling surface 4a of the dining space R2. The ceiling surface 4a is located so as to connect the ceiling surface 2a of the kitchen space R1 and the ceiling surface 2b of the dining space R2. Thus, the kitchen space R1 and the dining space R2 are integrated as one space. Even if there is a step between the ceiling surface 2a and the ceiling surface 2b, the step can be made inconspicuous by the ceiling surface 4a.

  As shown in FIG. 6, the upper part 10d of the falling wall 10 has a surface 20a on the kitchen space R1 side, a surface 20b on the dining space R2 side, and a lower end surface 20c. The lower end face 20c is formed on the lower end side of the upper part 10d of the falling wall 10 by removing the lower part 10e of the falling wall 10 by the repair method according to the present embodiment (see FIG. 8A). ).

The finishing material 41 is, for example, a cloth. The new finishing material 41 is a finishing material that is newer than the finishing material 21 that covers the ceiling surface 2b of the dining space R2. For example, the new finishing material 41 refers to a material that is newly attached to the ceiling surface 2a, the descending wall 10, or the like in accordance with the repair, and that has passed less time after being attached than the finishing material 21. The ceiling surface 2a on the kitchen space R1 side and the surfaces 20a, 20b and the lower end surface 20c of the upper portion 10d of the falling wall 10 may be continuously covered with a plurality of finishing materials 41 as shown in the drawing. It may be integrally covered with one finishing material 41. The surface 20b of the upper portion 10d of the descending wall 10 only needs to be at least partially covered with the finishing material 41, and may not be entirely covered with the finishing material 41.

  The finishing material 41 covering the lower end surface 20c of the upper portion 10d of the falling wall 10 is attached to a gypsum board 34 provided on the lower end side of the upper portion 10d of the falling wall 10 with an adhesive or the like. Therefore, a new finishing material 41 is attached to both the ceiling surface 2a on the kitchen space R1 side and the ceiling surface 4a located between the kitchen space R1 and the dining space R2. , 4a are assimilated. As a result, a sense of unity is given to the appearance of the repaired ceiling surfaces 2a and 4a.

  On the other hand, the ceiling surface 2b of the dining space R2 remains covered with the existing finishing material 21. Generally, the kitchen space R1 is smaller than the dining space R2. Therefore, in the repair method according to the present embodiment, the ceiling surface 2b of the dining space R2 is maintained as it is, and the ceiling surface 2a on the kitchen space R1 side, which requires less repair work, is repaired with a new finishing material 41. I have.

For example, the peripheral edge 51 is provided at a boundary portion 52 between the surface 20a of the upper portion 10d of the descending wall 10 and the ceiling surface 2a. The peripheral edge 51 has a band shape and covers the boundary portion 52 via the finishing material 41. In a height direction substantially perpendicular to the ceiling 2, the width of the peripheral edge 51 is substantially the same as the width of the upper portion 10d. Note that an existing peripheral edge 15 on the kitchen space R1 side may be provided instead of the new peripheral edge 51.

  Between the upper part 10d of the descending wall 10 and the dining space R2, a new peripheral edge 53 is provided as a parting material. For example, the peripheral edge 53 is provided at a boundary portion 54 between the surface 20b of the upper portion 10d of the descending wall 10 and the ceiling surface 2b. The peripheral edge 53 has a band shape and covers the boundary portion 54 via the finishing materials 41 and 21. That is, the peripheral edge 53 covers the end 41a of the finishing material 41 on the dining space R2 side. In a height direction substantially perpendicular to the ceiling 2, the width of the peripheral edge 53 is substantially the same as the width of the upper portion 10d. Note that an existing peripheral edge 17 on the dining space R2 side may be provided instead of the new peripheral edge 53.

Specifically, a new peripheral edge 53 is provided via the finishing materials 41 and 42 so as to cover the boundary portion 54 between the surface 20b of the upper portion 10d of the falling wall 10 and the ceiling surface 2b. That is, after the step of covering with the new finishing material 41, the peripheral edge 53 is provided so as to cover the end 41a of the finishing material 41 on the dining space R2 side. The existing peripheral edges 15, 17 may be provided again instead of the new peripheral edges 51, 53. As described above, the structure inside the renovated building 1 in which the kitchen space R1 and the dining space R2 are integrated is configured.

  As described above, according to the repair method according to the present embodiment, the lower portion 10e of the falling wall 10 provided between the kitchen space R1 and the dining space R2 is removed without changing the base material of the ceiling 2 or the like. Thus, the kitchen space R1 and the dining space R2 on both sides of the falling wall 10 can be integrated. Further, since the upper portion 10d of the descending wall 10 remains, even if there is a step between the respective ceiling surfaces 2a and 2b of the kitchen space R1 and the dining space R2, it can be made inconspicuous. In addition, the ceiling surface 2a of the kitchen space R1, the surface 20a of the upper portion 10d of the falling wall 10 on the kitchen space R1 side, and the lower end surface 20c of the upper portion 10d of the falling wall 10 are all new finishes. Since it is covered with the material 41, the upper part 10d of the descending wall is assimilated with the ceiling surface 2a of the kitchen space R1, so that a sense of unity can be given to the appearance. As described above, the repair work involving the removal of the falling wall 10 can be easily realized, and the appearance after the repair can be improved.

  In addition, according to the repair method according to the present embodiment, the ceiling surface 2a of the kitchen space R1 which is generally smaller than the dining space R2 is repaired, so that less repair work is required. Further, only the kitchen space R1 on which oil stains and the like are likely to adhere due to cooking or the like is renovated with the new finishing material 41, and the dining space R2 is left as it is.

  Further, according to the repair method according to the present embodiment, the end 41a of the new finishing material 41 is covered with the peripheral edge 53, so that the fitting is improved and the appearance can be further improved.

  Further, according to the repair method according to the present embodiment, since the object to be removed at the time of repair is the falling wall 10, the removal of the lower portion 10e is facilitated. Further, for example, the partition wall having a height from the floor surface to the ceiling surface is held on both the floor side and the ceiling side. Therefore, when such a partition wall is to be removed at the time of repair, there is a possibility that a problem may arise as to whether the upper portion of the partition wall remaining after removal of the lower portion of the partition wall can be structurally maintained. On the other hand, according to the repair method according to the present embodiment, since the object to be removed at the time of repair is the descending wall 10, the ceiling is originally firmly held by the ceiling 2 side. Therefore, even if the lower part 10e of the falling wall 10 is removed, the remaining upper part 10d of the falling wall 10 can be structurally maintained.

  In addition, according to the repair method according to the present embodiment, the kitchen space R1 and the dining space R2 can be integrated with a small repair work by removing the hanging storage 3 together with the lower portion 10e of the falling wall 10. Furthermore, since the falling wall 10 to which the hanging storage 3 is fixed is more firmly held on the ceiling 2 side so as to receive the load of the hanging storage 3, the lower part 10e of the falling wall 10 is removed. Also, the upper portion 10d of the remaining falling wall 10 can be reliably maintained structurally.

  Further, according to the repair method according to the present embodiment, even after the lower portion 10e of the descending wall 10 is removed, the wall base 11 that is able to win against the ridge 7 remains. Therefore, even after the lower part 10e of the falling wall 10 is removed, the state where the ends 7c and 7d of the respective ridges 7 on the kitchen space R1 side and the dining space R2 side are connected to each other by the wall base 11 is maintained. Therefore, even after the repair, the end of the ceiling 2 does not hang down, and the appearance can be improved.

  According to the modified wall structure 1a according to the present embodiment, the kitchen space R1 and the dining space R2 communicate with each other below the lower end surface 20c of the upper portion 10d. That is, the kitchen space R1 and the dining space R2 are integrated at the upper part 10d. Since the upper portion 10d projects below the ceiling surface 2a of the kitchen space R1 and the ceiling surface 2b of the dining space R2, a step is formed between the ceiling surfaces 2a and 4a of the kitchen space R1 and the dining space R2. Even if there is, it can be made inconspicuous. In addition, since the ceiling surface 2a of the kitchen space R1, the surface 20a of the upper portion 10d on the kitchen space R1 side, and the lower end surface 20c of the upper portion 10d are covered by the same finishing material 41, 10d is assimilated with the ceiling surface 2a of the kitchen space R1, so that a sense of unity can be given to the appearance. Therefore, the appearance after the repair can be improved.
