Description

  The present invention relates to a wall surface material replacement method and a wall body in which the wall surface material is replaced by the replacement method.

  For example, a steel house is known as a building constructed by a frame wall construction method. In the steel house, the wall body has a frame body composed of a pair of upper and lower runners and a plurality of studs provided between the runners. The wall material is screw-fixed on both sides of the frame (see, for example, Patent Document 1 for the wall). In this case, in the steel house, the wall body is used as a load-bearing wall, and the ceiling surface material is fixed so as to abut against the indoor side surface of the wall body, for example.

JP 2002-285660 A

  Here, in a wall of a building such as a steel house, it is conceivable that the wall material is damaged by shaking such as an earthquake, or the wall material is damaged by hitting something. In this case, when the wall surface material is replaced, the wall surface material is generally replaced integrally from the upper end portion to the lower end portion of the wall body. This is because there is no base material between the upper and lower runners in the wall body, and considering the strength of the wall body after the replacement, it is considered that the entire wall surface replacement is desirable. In this case, there is a concern that the replacement work of the wall surface material becomes a large scale and the work becomes complicated.

  In addition, if the ceiling surface material is abutted against and fixed to the indoor side surface of the wall body, the wall surface material will be replaced after the ceiling surface material is removed. The work becomes extremely complicated.

  In addition to the case where it is used as a load-bearing wall of a steel house, it has a frame body composed of a pair of upper and lower runners and a plurality of studs provided between the runners as described above, and wall surfaces on both sides across the frame body Regarding the frame to which the material is fixed, it is considered that the same inconvenience as described above occurs when the wall surface material is replaced.

  The present invention has been made in view of the above circumstances, and a main object of the present invention is to provide a wall surface material replacement method and a wall body capable of simplifying wall surface material replacement work. .

  Hereinafter, means and the like effective for solving the above-described problems will be described while showing functions and effects as necessary.

The method of replacing the wall material of the first invention is as follows:
As a building wall, it has a frame body composed of a pair of upper and lower frame runners and a plurality of studs provided at predetermined intervals between the two runners, and on both sides of the frame body It has a structure in which a wall surface material is fixed, and is a re-stretching method for re-slacking a part of the wall surface material for the wall body,
A first step of cutting the wall material to be repositioned in a range from one stud to another stud among the plurality of studs;
Then, in the part where the wall surface material is excised, a second step of attaching the base horizontal member with both ends fixed to the adjacent studs, and
Thereafter, in the site where the wall material is excised, a third step of fixing the wall material for restretching to the base horizontal member;
It is characterized by having.

  According to the above replacement method, for example, when a part of the wall surface material is damaged, the entire surface of the wall surface material does not need to be replaced, and can be dealt with by partial repair. In such a case, both ends of the base horizontal member are fixed to the studs, and the strength as the wall body is ensured in the portion where the wall surface material is replaced. In addition, since the replacement can be performed only at a necessary portion, the replacement work can be simplified.

In the second invention,
The second step includes
Attaching the support from between adjacent studs to the stud exposed by excision of the wall material in the first step; and
The step of attaching the base horizontal member to the attached support so that the side surface portion of the stud and the base horizontal member on the wall surface material replacement side is flush,
It is characterized by including.

  According to the above replacement method, since the base horizontal member is attached to the support in a state where the support is attached first, the attachment work can be facilitated. The support tool is attached from between adjacent studs, and in the state where the wall surface material is cut off, the support tool can be easily attached. In addition, in the state that the base horizontal member is attached to the support, the side wall of the stud and the base horizontal member on the side of the wall material replacement side is flush, so that the wall surface material that cannot be replaced (non-replaceable) (Part) and a newly re-walled wall material for re-hanging will not cause a step, and the finish will be good.

  In addition, as a structure which attaches a base horizontal material to a stud, the base horizontal material which consists of a strip board material in the side surface part (in the case of a stud which consists of a grooved rope, the flange outer surface) of the stud wall surface material A configuration in which the material is directly attached is conceivable. However, in this case, considering the thickness of the belt plate material, the presence of fixing screws, etc., there is a risk that a step will be produced between the wall material of the non-replacement portion and the wall surface material for reconstitution. On the other hand, according to the re-stretching method, a step does not occur between the wall surface material of the non-re-stretched portion and the wall surface material for re-stretching, and the finish is good.

In the third invention,
The stud and the base horizontal member are made of channel steel,
The second step includes
Fixing the angle material as the support to the stud, with one side abutting against the web portion of the stud and the other side extending toward the center between adjacent studs;
Attaching the base horizontal member to the other side of the angle member;
It is characterized by including.

  According to the above replacement method, the base horizontal member can be easily attached by combining the angle member and the channel steel, and the replacement of the wall member can be easily performed. Also, by using grooved steel as the base horizontal member, even if the wall surface material for replacement is pressed to the back side when the wall material for replacement is fixed to the base horizontal member with screws or the like, The bending of the wall material for the replacement can be suppressed.

  When channel steel is used as the base horizontal member, the base horizontal member may be attached in a direction in which the web surface is a horizontal plane, and the flange outer surface may be used as the attachment surface of the wall surface material for replacement. In this case, a grooved steel having the same web width as the stud may be used as the base horizontal member. Alternatively, the base horizontal member may be attached in a direction in which the web surface becomes a vertical surface, and the outer surface of the web may be used as the attachment surface of the wall material for replacement.

In the fourth invention,
In the second step, in the side surface portion of the stud on the wall surface material replacement side, a part of one side viewed in the vertical direction is overlapped with the wall material remaining without being cut, and the remaining part is newly replaced by the replacement The base horizontal member is attached so as to be a portion where the wall surface material is overlapped.

  According to the above replacement method, the base horizontal member provided at the boundary between the non-excised portion and the excised portion of the wall material is separated from the wall material (non-exchangable portion) that remains uncut and the newly-extended tension material. It can be shared as a fixed support partner with the wall material for replacement. Accordingly, the wall surface material can be fixed with a desired strength without adding an excessive amount of the base horizontal member at the boundary portion between the non-excised portion and the cut portion of the wall surface material.

In the fifth invention,
In the first step, in the side surface portion of the stud on the wall surface material replacement side, a part of one side when viewed in the lateral direction is a region where the wall surface material is not cut, and the remaining portion is a region where the wall surface material is cut. The wall material is excised from the area to be excised.

  According to the above replacement method, the stud at the boundary between the non-excised portion and the excised portion of the wall material is left uncut and the wall material (non-exchangable portion) that is re-exposed, Can be shared as a fixed support partner. Thereby, a wall surface material can be fixed with a desired intensity | strength, without adding a stud in the boundary part of the non-excision part of a wall surface material, and an excision part.

In the sixth invention,
The wall body is used as a load-bearing wall on the outer wall portion of a building constructed by a framework wall construction method,
In the building, a ceiling surface material is fixed to the wall surface on the indoor side of the wall body in a direction intersecting with the wall surface,
In the wall surface material, the wall surface material is replaced below the fixed position of the ceiling surface material.

  In a building constructed by the frame wall construction method, if the wall material to which the end of the ceiling surface material is fixed (that is, the wall material on the inner wall side) is damaged, A great load is generated in the reworking work, but according to the reworking method, the load of the reworking work can be greatly reduced. That is, when the wall surface material is replaced, the work for removing the ceiling surface material is not required, so that workability is greatly improved.

In the seventh invention,
The wall body includes, as the plurality of studs, a first stud disposed at a peripheral portion of the wall surface material and a second stud disposed other than the peripheral portion, and the wall surface with respect to the first stud. The fixing interval for fixing the screw to the material is smaller than the fixing interval for fixing the wall member to the second stud.
In the third step, when the wall surface material for replacement is fixed to the stud and the base horizontal member, at the same fixing interval as the fixing interval for fixing the wall surface material to the first stud, It is characterized in that the wall material for re-stretching is fixed with screws.

  In order to secure the strength as the load-bearing wall in the wall body, the first stud arranged at the peripheral portion of the wall surface material is screw-fixed at a relatively narrow interval, and the second stud arranged at the portion other than the peripheral portion is fixed thereto. Screw fixing may be performed at a relatively wide interval. In view of this, when a part of the wall material is replaced, the wall material for replacement is applied to the stud and the base horizontal member at the same fixing interval as the screw fixing the wall member to the first stud. Secure the screw. Thereby, the intensity | strength as a load-bearing wall is maintainable about the wall body in which the wall material was partially replaced.

  In addition, the part which becomes a cutting end part in the original wall surface material which remains unreplaced may be re-visited with the same fixed interval as the fixed interval for fixing the wall surface material to the first stud.

  The wall body (eighth invention) in which the wall surface material is replaced by each of the above replacement methods is favorable in terms of strength and finish after the replacement.

  DESCRIPTION OF EXEMPLARY EMBODIMENTS Hereinafter, an embodiment of the invention will be described with reference to the drawings. In the present embodiment, the present invention is embodied in a wall body (outer wall panel) used as a load bearing wall in a steel house constructed as a building by a frame wall construction method. 1A and 1B are diagrams showing the configuration of the wall body 10, where FIG. 1A is a front view of the wall body 10, and FIG. 1B is a cross-sectional view of the wall body 10. In addition, in Fig.1 (a), the state which cut off the upper part of wall surface material is shown. Further, in (b), for the sake of convenience, the thickness of the steel material is omitted, and the portions that are actually brought into contact with each other are also shown slightly separated (the same applies to FIG. 3 described later).

  As shown in FIG. 1, the wall body 10 is a frame (wall skeleton) 11, which is a pair of upper and lower frame runners 12 and 13, and a predetermined distance between the runners 12 and 13. A plurality of studs 14 are provided, and wall surface materials 15 and 16 are respectively fixed to both sides of the frame body 11. Each of the upper and lower runners 12 and 13 is made of a lipless channel steel, and both are arranged so that the groove portions face inward in the vertical direction. The plurality of studs 14 are made of lip-shaped channel steel, and are bridged between the upper and lower runners 12 and 13 with their upper and lower ends inserted into the grooves of the runners 12 and 13. Thus, they are arranged in parallel to each other. Each stud 14 is provided in a direction in which the groove portions are all in the same direction. The installation interval (L1 in the figure) of the studs 14 is preferably determined based on the building module of the building. In this embodiment, the studs 14 are provided with L1 = 450 mm, for example, based on the scale module.

  The lip-shaped channel steel constituting the stud 14 will be described. As shown in FIG. 2, the lip-shaped channel steel has a web 18a, a flange 18b, and a lip 18c. The size is not limited, but specific numerical values are exemplified such that the length L2 of the web 18a is 89 mm, the length L3 of the flange 18b is 45 mm, and the length L4 of the lip 18c is 12 mm.

  Returning to the description of FIG. 1, the wall surface materials 15 and 16 are configured such that the wall surface material 15 on the indoor side is constituted by an inner wall material such as gypsum board, and the wall surface material 16 on the outdoor side is formed by an outer wall material such as a ceramic siding board. It is configured. The wall surface materials 15 and 16 are plate materials 15a having a size in which the vertical dimension is the same as that of the upper frame runner 12 to the lower frame runner 13, and the lateral dimension L5 is n times the stud installation interval (n is an integer of 2 or more). 16a, and a plurality of these plate members 15a and 16a are bonded to the frame 11. As for the size of each of the plate members 15a and 16a, for example, the vertical dimension is 2630 mm, and the horizontal dimension L5 is 900 mm (= L1 × 2). In addition, it is also possible to make the size (for example, horizontal dimension) of board | plate material 15a, 16a different on the outer wall side and the inner wall side.

  The plate member 15a is fixed to the frame body 11 with screws at predetermined positions at predetermined intervals, and the intervals between the screw members are different depending on the position of the peripheral portion of the plate member 15a and the others. Yes. In the drawing, the symbol Vs (black circle portion) indicates the screwing position. In the present embodiment, the screwing interval (fixed interval) L6 at the position of the peripheral portion of the plate member 15a is 150 mm, and the screwing interval (fixed interval) L7 at other positions is 300 mm. That is, the plate material 15a is screwed to the upper and lower runners 12 and 13 at intervals of 150 mm. Further, among the studs 14 to the stud (14A in the figure) to which the lateral edge of the plate material 15a is fixed, the plate material 15a is screwed at intervals of 150 mm, and the intermediate portion of the plate material 15a is fixed when viewed in the left-right direction. For the stud (14B in the figure), the plate material 15a is screwed at intervals of 300 mm. The stud 14A corresponds to the first stud, and the stud 14B corresponds to the second stud.

  In this way, the screws are fixed at a relatively narrow interval at the position that becomes the peripheral portion of the plate material 15a. On the other hand, the screws are fixed at a relatively wide interval except for the peripheral portion. In the wall body 10, the strength as the bearing wall can be secured.

  Here, in particular, at the lateral edge portion of the plate material 15a, the plate material 15a is overlapped with the stud 14A to which the lateral edge portion is fixed in the region about half of the flange of the stud 14A, and screwing is performed at the overlapped portion. ing. That is, the stud 14A to which the lateral edge portion of the plate material 15a is fixed is configured such that the left and right two plate materials 15a are fixed to the same flange, and the left and right two plate materials 15a are provided in each region divided into two laterally. Each is screwed.

  The outdoor side plate material 16a is similarly fixed to the frame 11 with screws. However, according to the difference in the material of plate material 15a, 16a, etc., the space | interval of the screw stop of each plate material 15a, 16a may be set separately, respectively.

  By fixing the plate members 15a and 16a to the frame body 11 as described above, the required strength of the wall body 10 as a bearing wall is satisfied.

  Moreover, FIG. 3 is sectional drawing which shows the structure of the ceiling vicinity of a building. In a building, a field edge runner 21 made of grooved steel (long material) is fixed to the indoor side surface of the wall body 10 as an outer wall panel, that is, the indoor side surface of the wall material 15 in a direction extending in the horizontal direction. A field edge 22 made of a long material is fixed in a direction intersecting (orthogonal) with the field edge receiving runner 21. A ceiling member 23 is fixed to the lower surface side of the field edge 22. In this case, when the building is constructed, the wall body 10 is installed in advance, and then the ceiling surface material 23 is fixed so as to abut against the indoor side surface of the wall body 10 (that is, the indoor side surface of the wall surface material 15). . In other words, it has a so-called wall winning structure.

  By the way, in a building having the wall body 10 having the above configuration, when a deformation load due to an earthquake or the like acts on the wall body 10 or an object collides with the inner wall surface of the wall body 10, a wall surface material 15 (for example, a gypsum board on the inner wall side). ) May be damaged. In this embodiment, when a part of wall surface material 15 is damaged, the replacement method which can implement suitably the replacement of a wall surface material about the damaged part is proposed.

As an overview,
(1) a wall surface material cutting step (first step) for cutting the plate material 15a to be replaced in the wall surface material 15 in a range from one of the two adjacent studs 14 to the other;
(2) After that, in the part where the wall surface material 15 is excised, a base material adding step (second step) for attaching the base horizontal member with both ends fixed to the adjacent studs,
(3) After that, in the site where the wall surface material 15 has been excised, a tensioning step (third step) for fixing the wall surface material for tensioning to the base material;
Each of these steps will be described in detail below. FIG. 4 is a front view of the wall body 10 for explaining the above steps. 5A is a cross-sectional view taken along line AA in FIG. 4B, FIG. 5B is a cross-sectional view taken along line BB in FIG. 4C, and FIG. 5C is FIG. It is a CC sectional view taken on the line of FIG.

(1) Wall surface material cutting process As shown to Fig.4 (a), when a part (x part of a figure) of board | plate material 15a (wall surface material 15) is damaged, the area | region (hatching area | region of a figure) including the damaged part Is defined as a cutting position, and the plate material 15a is cut out using a cutting tool such as a cutter for the region. In FIG. 4B, S is a region where the plate material 15a is cut out, and in this example, a portion that is an intermediate position when viewed in the vertical direction is a cut portion. The cutting of the plate material 15a is performed with the wall body 10 still attached to the building. That is, as described above, the ceiling member 23 is attached to the wall 10 on the indoor surface side, but the plate member 15a is partially removed at the lower part of the ceiling with the ceiling member 23 attached. . In this case, the plate material 15a is cut out in the range from one of the two adjacent studs 14 to the other, and the flanges of the adjacent studs 14 (the side surface portion on the wall surface material replacement side). The plate material 15a is cut out in the region to be cut out, with a part on one side as viewed in the lateral direction being a region where the plate material 15a is not cut and the remaining portion being a region where the plate material 15a is cut.

  Specifically, as shown in FIG. 5A, in a state where a part of the plate material 15a is cut off, the edge of the plate material 15a is the flange of the stud 14 at the boundary end adjacent to the cut portion (S region). The other half of the flange is an exposed portion where the plate material 15a does not overlap (Z in the figure).

(2) Substrate material addition step As shown in FIG. 4 (c), with respect to both studs 14 adjacent to the boundary end portion of the plate material 15a vertically adjacent to the cut portion in the cut portion (S region) of the plate material 15a. The base horizontal member 25 is attached with both ends fixed. FIG. 6 is a perspective view showing the mounting structure of the base horizontal member 25, which corresponds to the structure of the Y portion in FIG. 4 (c).

  Specifically, as shown in FIGS. 5B and 6, the left and right studs 14 exposed by cutting the plate material 15 a are attached to the left and right studs 14 with screws or the like from between adjacent studs, The base horizontal member 25 is attached to each of the attached supports 26 so that the side surface portion (flange outer surface) of the stud 14 and the base horizontal member 25 on the wall surface material replacement side is flush. In this case, as shown in FIG. 6, the support 26 is an angle member formed by bending a steel plate into an L shape, and one plate portion 26a (one side portion) of the angle member is screwed to the web of the stud 14 or the like. It is fixed by. The other plate portion 26b (the other side portion) extends to the opposite side of both adjacent studs 14 with the plate surface in the horizontal direction, and the base horizontal member 25 is screwed to the plate portion 26b. It is fixed by. 6 is a boundary line indicating the position of the end of the plate member 15a on the outer surface of each flange of the stud 14 and the base horizontal member 25. In addition, as a method of bonding the support tool 26 to the stud 14 or the base horizontal member 25, other bonding methods such as an adhesive can be used.

  Two adjacent studs 14 are provided with the groove portions oriented in the same direction, and therefore one of the pair of left and right support members 26 is attached to the groove side surface (inner side surface) of the web of the stud 14. And the other is attached to the anti-groove side surface (outer surface) of the web of the stud 14.

  The base horizontal member 25 is a lip-shaped grooved steel having the same size as the stud 14 (at least a grooved steel having the same web width), and is attached so that the web is a horizontal surface and the flange is a vertical surface. At this time, since the web width of the stud 14 is the same, the flange outer surface of the stud 14 and the flange outer surface of the base horizontal member 25 are flush with each other.

(3) Re-stretching step As shown in FIG. 4 (d), a new re-stretching plate member 28, which is a re-walling wall material, is screwed to the stud 14 and the base horizontal member 25 at the site where the plate member 15a is cut. Fix with etc. The tension plate 28 is made of the same plaster boat or the like as the plate 15a, and is arranged without a gap with respect to the plate 15a in the non-replacement portion.

  Specifically, as shown in FIG. 5C, the tension plate member 28 is disposed so as to overlap each of the adjacent studs 14 and the base horizontal member 25, and the stud 14 and the base horizontal member 25. The tension plate member 28 is fixed with screws or the like. At this time, the screw fixing interval L8 is the same as the fixing interval L6 (see FIG. 1) at the peripheral edge of the plate member 15a, and is fixed with screws at intervals of 150 mm, for example. This is the same for not only the fixed portion of the tension plate member 28 to the base horizontal member 25 but also the fixed portion of the stud 14 to the stud 14 and is screw-fixed at the same interval L8 as the fixing interval L6 (see FIG. 1). In other words, all the peripheral edges of the four sides of the stretchable plate material 28 are opposed to the stud 14 or the base horizontal member 25, and screw fixing is performed at the same interval L8 as the fixing interval L6 at the facing portion. Yes. However, the fixed interval L8 may be smaller than the fixed interval L6.

  In the plate material 15a that remains without being cut (the non-cut plate material 15a), the screw fixing interval is also the same as the fixing interval L6 (see FIG. 1) at the peripheral edge of the plate material 15a. Good. In other words, in FIG. 4D, at the cut end position of the plate material 15a adjacent to the tension plate material 28 in the vertical and horizontal directions, the plate material 15a is located at the same interval as the fixed interval L6 with respect to the stud 14 and the base horizontal member 25. The screw is fixed. Note that the stud 14 (14B in the figure) fixing the intermediate portion of the plate material 15a is originally screw-fixed at a fixing interval L7 (see FIG. 1), but this screw is removed and newly added to it. Screws are fixed at narrow intervals.

  Incidentally, although details are not described, the decorative cloth on the inner wall surface is appropriately peeled off and reattached after the wall surface material 15 is replaced during the above-described reworking operation. The above-described stretching method can also be applied to the replacement of the wall material 16.

  As for the case where the plate material 15a (wall surface material 15) is replaced, in addition to the case where the plate material 15a is damaged during an earthquake or the like as described above, or when the plate material 15a is damaged due to an impact, indoor moisture ( For example, the plate 15a may be corroded due to water wet behind the washing machine, or may be damaged due to submersion due to water damage. Even in such a case, the above-described rehanging method can be applied. In addition to the purpose of repairing at the time of breakage or the like, the above replacement method can also be applied when a resident or the like intentionally replaces the wall material.

  Another method is also conceivable as a method for attaching the base horizontal member (base material adding step). This will be described with reference to FIGS. FIG. 7 is a cross-sectional view of the wall in the base material adding step, which corresponds to a cross-sectional view taken along the line BB in FIG. 4C (however, in FIG. I want to replace it with the base material 31). 8 is a perspective view showing the mounting structure of the base horizontal member 31, which corresponds to the structure of the Y portion in FIG. 4C (however, the direction of the groove opening is reversed).

  In the base material addition step, as shown in FIGS. 7 and 8, for each of the left and right studs 14 exposed by excision of the plate material 15a, the support tool 32 is attached by screws or the like from between adjacent studs, The base horizontal member 31 is attached to each of the attached support tools 32 so that the side surface portions of the stud 14 and the base horizontal member 31 on the wall surface material replacement side are flush with each other. In this case, as shown in FIG. 8, the support 32 is an angle member formed by bending a steel plate into an L shape, and one plate portion 32 a (one side portion) of the angle member is screwed to the web of the stud 14. It is fixed by. The other plate portion 32b (the other side portion) extends to the other side of the adjacent studs 14 with the plate surface in the vertical direction, and the base horizontal member 31 is screwed to the plate portion 32b. It is fixed by.

  The two adjacent studs 14 are provided with the groove portions oriented in the same direction, and therefore one of the pair of left and right support members 32 is on the side opposite to the groove (outer side surface) of the web of the stud 14. The other is attached to the outer surface of the lip of the stud 14. The base horizontal member 31 is a lip-shaped channel steel having the same size as the stud 14 and is attached so that the web is a vertical surface. However, in the configuration of FIG. 8, the size of the channel steel as the base horizontal member 31 is arbitrary. 8 is a boundary line indicating the position of the end portion of the plate material 15a on the flange outer surface of the stud 14 and the web outer surface of the base horizontal member 31.

  In the mounting structure of the base horizontal member 31 shown in FIGS. 7 and 8, the base horizontal member 31 and the support member 32 overlap each other when viewed in the wall thickness direction. It is fixed to the web of the stud 14 in a state of retreating inward in the wall thickness direction by the plate thickness. In addition, since the support tool 32 partially overlaps in the wall thickness direction with respect to a part of the plate material 15a (the upper end portion and the lower end portion) that remains without being cut off, the base material is provided between the plate material 15a and the support tool 32. In order to insert the horizontal member 31, the flange of the base horizontal member 31 becomes an obstacle. Therefore, a notch 31a for avoiding interference is provided in the flange of the base horizontal member 31 (for example, the upper flange in the place of FIG. 8). According to the notch 31a, when the base horizontal member 31 is inserted between the plate member 15a and the support 32, the base horizontal member 31 can be disposed so as to straddle the plate member boundary as shown in FIG. .

  According to the embodiment described in detail above, the following excellent effects can be obtained.

  According to the wall surface material replacement method described in detail with reference to FIGS. 4 to 8, for example, when a part of the plate material 15 a (wall surface material 15) is damaged, the entire surface of the plate material 15 a need not be replaced. Can be dealt with by partial repair. In such a case, both ends of the base horizontal member 25 are fixed to the studs 14, and the strength as the wall body 10 is ensured at the portion where the plate member 15a is replaced. In addition, since the replacement can be performed only at a necessary portion, the replacement work can be simplified.

  When the wall material is replaced, a support 26 is attached from between adjacent studs to the stud 14 exposed by cutting the plate material 15a, and the stud 14 and the base horizontal member 25 are connected to the support 26. The base horizontal member 25 was attached so that the side surface portion on the wall surface material replacement side (flange outer surface of the groove-shaped rope) was flush. In this case, since the base horizontal member 25 is attached to the support 26 in a state where the support 26 is attached first, the attachment work can be facilitated. Further, since the side surface portion of the stud 14 and the base horizontal member 25 on the wall surface material replacement side is flush with each other, a step is generated between the plate material 15a (non-replacement portion) that cannot be repositioned and the tension plate material 28. The finish is good.

  An angle member as the support tool 26 is used, and the base horizontal member 25 is attached to the support tool 26. According to this rehanging method, the base horizontal member 25 can be easily attached by combining the angle member and the grooved steel, so that the wall member can be easily replaced. Further, by using channel steel as the base horizontal member 25, even when the tension plate 28 is pressed to the back side when the tension plate 28 is fixed to the base horizontal member 25 with screws or the like, The bending of the replacement plate material 28 can be suppressed.

  Further, when the base horizontal member 25 is attached to the stud 14, a part of one side of the base horizontal member 25 as viewed in the vertical direction is overlapped with the remaining plate member 15a without being cut, and the remaining part is newly stretched. The replacement plate material 28 was overlapped. As a result, the base horizontal member 25 provided at the boundary between the non-cut portion and the cut portion of the plate member 15a can be shared as a fixed support partner for the non-cut plate member 15a and the replacement plate member 28. Thereby, each board | plate material can be fixed by desired intensity | strength, without adding the base horizontal member 25 excessively in the boundary part of a non-excision part and an excision part.

  Further, when part of the plate material 15a is cut, a part of one side of the flange 14 on the outer surface of the stud 14 as viewed in the horizontal direction is a region where the plate material 15a is not cut, and the remaining part is a region where the plate material 15a is cut. The plate material 15a was excised from the area to be excised. Thereby, the stud 14 (for example, the stud 14B in FIG. 4D) at the boundary between the non-cut portion and the cut portion of the plate material 15a can be shared as a fixed support partner for the non-cut plate material 15a and the replacement plate material 28. . Thereby, each board | plate material can be fixed with desired intensity | strength, without adding the stud 14 in the boundary part of the non-cut | disconnected part and cut | disconnected part of the board | plate material 15a.

  In the above replacement method, the plate material 15a (wall surface material 15) can be replaced in the wall 10 below the fixed position of the ceiling surface material 23. When the inner wall side plate member 15a to which the end of the ceiling surface member 23 is fixed is damaged, if the plate member 15a is entirely replaced, a great load is generated in the replacement work. According to this, the load of the replacement work can be greatly reduced. That is, when the plate material 15a (wall surface material 15) is replaced, the work of removing the ceiling surface material 23 is not necessary, so that workability is greatly improved.

  About the site | part fixed to the stud 14 and the base horizontal material 25 in the tension | change_over board material 28 with the screw | thread, it is the same fixation as the fixed space | interval which fixes the board | plate material 15a to the stud 14 (1st stud) of the peripheral part of the board | plate material 15a. Screws are fixed at intervals, and the plate material 15a is screw-fixed to the stud 14 (first stud) at the peripheral edge of the plate material 15a at a portion that becomes a boundary portion between the non-cut portion and the cut portion in the plate material 15a. Screw fixing was performed at the same fixed interval as the fixed interval. Thereby, the intensity | strength as a load-bearing wall can be maintained about the wall body 10 in which the plate material 15a (wall surface material 15) was partially replaced.
