Summary of the Invention

Problems to be Solved by the Invention

[0004] However, in the inner wall base structure described in Patent Document 1, it was impossible to attach a base material to the vertical member of the column at the corner of the inner wall of the building because it was at the corner.

[0005] Therefore, in view of the above circumstances, the present invention provides an inner wall base structure in which a base material is provided around a vertical member even when the base material cannot be attached to the vertical member itself used in the inner wall.

Means for Solving the Problems

[0006] The inner wall base structure according to the present invention includes a long vertical member used for the inner wall of a building, a vertical support member extending in parallel adjacent to the vertical member, a cover base material fixed to the vertical support member and disposed around the vertical member to form a U-shaped inner wall base in a cross-sectional view, and a fixing fitting for fixing the cover base material to the ceiling portion or the floor portion of the building.

[0007] It is characterized in that there is a gap between the vertical member and the cover base material.

[0008] The fixing bracket comprises a vertical fixing plate fixed to the cover base material, a horizontal fixing plate fixed to the ceiling or floor, and an inclined fixing plate positioned between the vertical fixing plate and the horizontal fixing plate in a side view, and the cover base material is characterized in that its end is sandwiched and fixed between the vertical fixing plate and the inclined fixing plate.

[0009] The vertical fixing plate is characterized in that it has holes that are the same size as or larger than those of the inclined fixing plate, and these holes are provided so as to coincide with those of the vertical fixing plate. [Effects of the Invention]

[0010] According to the present invention, since a cover base material that forms an interior wall base in a U-shape in cross-section is arranged around a long length used in the interior wall of a building, the base material can be provided around the vertical members.

[0011] Furthermore, since there is a gap between the vertical members and the cover base material, the insertion member that penetrates the cover base material can be prevented from reaching the vertical members.

[0012] Furthermore, since the cover base material is secured by being sandwiched between the vertical fixing plate and the inclined fixing plate at its ends, the cover base material can be secured from both directions across its surface.

[0013] Furthermore, since the vertical fixing plate has holes that are the same size as or larger than those of the inclined fixing plate, it is possible to prevent the vertical fixing plate from tipping backward by releasing the force from the holes when an insertion member is inserted.

[0015] The interior wall substrate structure 100 according to the present invention will be described in detail below with reference to the drawings.

[0016] (Regarding the interior wall substrate structure 100) Figure 1 shows a schematic perspective view of the interior wall base structure 100 according to the present invention. The interior wall base structure 100 is mainly used at the corners and ends of interior walls in buildings. The interior wall base structure 100 mainly comprises vertical members 10 extending vertically in the interior wall of a building, vertical support members 20 extending parallel to and adjacent to the vertical members 10, cover base material 30 fixed to the vertical support members 20 and arranged around the vertical members 10, forming a U-shaped interior wall base in cross-section, and fixing fittings 60 that fix the end 31 of the cover base material 30 to the ceiling 40 or floor 50.

[0017] The floor part 50 is a part that constitutes the indoor space of a building, and is a floor material that forms the floor surface at the lower part of the interior, such as a floor finishing material, a floor base material, and a flooring. The ceiling part 40 is a part that constitutes the indoor space of a building, and is a ceiling material that forms the ceiling surface at the upper part of the interior, such as a ceiling finishing material and a ceiling base material, which partitions the room from the floor below the upper floor and the attic.

[0018] (Regarding the fixing fitting 60) As shown in FIGS. 2 and 3, the fixing fitting 60 is a fitting having a substantially L-shaped side view, and fixes the cover base material 30 and the ceiling part 40 or the floor part 50 of the building. As shown in FIG. 1, the fixing fitting 60 fixes the middle surface of the cover base material 30 having a U-shaped cross section in cross-sectional view and the ceiling part 40 or the floor part 50. That is, it is positioned so as to face the vertical support member 20.

[0019] The fixing fitting 60 mainly consists of two parts: an upper fixing fitting 70 on the ceiling part 40 side and a lower fixing fitting 80 on the floor part 50 side. The upper fixing fitting 70 fixes the upper end 31a of the middle surface of the cover base material 30 and the ceiling part 40. The lower fixing fitting 80 fixes the lower end 31b of the middle surface of the cover base material 30 and the floor part 50.

[0020] In this embodiment, the fixing fitting 60 is fixed to the middle surface of the cover base material 30. However, if necessary, it may be fixed to both side surfaces of the cover base material 30, or may be fixed to the three surfaces of both side surfaces and the middle surface.

[0021] The upper fixing fitting 70 mainly includes a vertical fixing plate 62a for fixing the cover base material 30, a horizontal fixing plate 61a fixed to the ceiling part 40, an inclined fixing plate 63a that is positioned between the vertical fixing plate 62a and the horizontal fixing plate 61a in side view and is inclined, and a hole 64.

[0022] Similarly, the lower fixing fitting 80 mainly includes a vertical fixing plate 62b for fixing the cover base material 30, a horizontal fixing plate 61b fixed to the floor part 50, an inclined fixing plate 63b that is positioned between the vertical fixing plate 62b and the horizontal fixing plate 61b in side view and is inclined, and a hole 64.

[0023] (Regarding the horizontal fixing plate 61) The horizontal fixing plates 61a and 61b are plates that are fixed to the ceiling portion 40 or the floor portion 50. They are fixed to the ceiling portion 40 or the floor portion 50 at least two locations by insertion members S. The horizontal fixing plates 61a and 61b may be provided with insertion holes for insertion.

[0024] As shown in Figure 2, the corners of the horizontal fixing plates 61a and 61b are chamfered. Chamfering helps prevent injuries to the installer.

[0025] (Regarding the vertical fixing plate 62) As shown in Figure 1, the vertical fixing plates 62a and 62b are located on the inner side of the cover base material 30. Therefore, even when the insertion member S is driven in from the inclined fixing plate 63, the vertical fixing plates 62a and 62b support the cover base material 30 with a surface, preventing the force from escaping to the back side. Because it is supported by a surface rather than a point, the cover base material 30 can be supported stably.

[0026] In this embodiment, the vertical fixing plate 62 is formed to be approximately perpendicular to the horizontal fixing plate 61. However, if the vertical member 10 is fixed to the ceiling portion 40 or floor portion 50 at an angle rather than at a right angle, the upper fixing bracket 70 and the lower fixing bracket 80 may also be formed to be at the same angle.

[0027] Furthermore, the width of the vertical fixing plate 62 is always formed to be shorter than the middle surface of the cover base material 30. Therefore, the same type of fixing bracket 60 can be used even if the wall thickness changes, without having to prepare fixing brackets 60 according to the wall thickness.

[0028] As shown in Figure 2, the corners of the vertical fixing plate 62 are chamfered. Chamfering helps prevent injuries to the installer.

[0029] (Regarding the inclined fixing plate 63) The inclined fixing plate 63 is located between the vertical fixing plate 62 and the horizontal fixing plate 61 in a side view and is an inclined plate. As shown in Figure 3(c), in normal circumstances, the inclined fixing plate 63 rises from the intersection of the vertical fixing plate 62 and the horizontal fixing plate 61 in a side view and is inclined toward the vertical fixing plate 62. The inclination angle of the inclined fixing plate 63 can be freely changed when attaching the cover base material 30 or when fixing the inclined fixing plate 63 with the insertion member S.

[0030] Furthermore, as shown in Figure 1, the inclined fixing plate 63 and the vertical fixing plate 62 sandwich the middle surface of the cover base material 30, so that the inclined fixing plate 63 is fixed to the outer surface of the cover base material 30 and the vertical fixing plate 62 is fixed to the inner surface of the cover base material 30.

[0031] Then, by inserting a screw or other insertion member S through the inclined fixing plate 63, the fixing bracket 60 can be fixed to the cover base material 30.

[0032] The inclined fixing plate 63 is provided with holes 64 that are the same size as or larger than the inclined fixing plate 63. In this embodiment, the inclined fixing plate 63 is formed by cutting the vertical fixing plate 62 into a rectangular shape and then tilting it, so the holes 64 and the inclined fixing plate 63 coincide.

[0033] When inserting a screw or other insertion member S from above the inclined fixing plate 63, since it has a hole 64, the insertion member S passes through the hole 64 of the vertical fixing plate 62, preventing force from being transmitted to the vertical fixing plate 62 in the direction of the vertical support member 20, and instead exiting through the hole 64. This prevents the vertical fixing plate 62 from falling inwards, and allows the cover base material 30 to be fixed stably.

[0034] As shown in Figure 1, the corners of the inclined fixing plate 63 are chamfered. Chamfering helps prevent injuries to the installer.

[0035] (Regarding vertical members 10) The vertical member 10 is a long member that extends in a straight line in the interior wall of the building and is not suitable for use as a base material. In this embodiment, the vertical member 10 is a structural column made of steel that extends in a straight line vertically in the interior wall and supports the vertical load of the building, and cannot be fastened with through members such as screws.

[0036] Furthermore, as shown in Figures 1 and 4, the upper and lower ends of the vertical members 10 are cylindrical round steel bars, while the other intermediate parts are rectangular prism-shaped square steel bars. The vertical members 10 used in the interior walls of a building may be pipes, piping, etc., and are not limited to structural columns. Also, even if they do not extend vertically, the vertical members 10 may extend diagonally using bracing, as in a load-bearing wall.

[0037] (Regarding cover base material 30) As shown in Figure 1, the cover base material 30 is a long base material formed from thin sheet metal in a U-shape in cross-section, and is arranged around the vertical members 10. By providing the cover base material 30, interior wall material I such as gypsum board can be attached around the vertical members 10, which cannot be used as a base material.

[0038] Since the cover base material 30 has a U-shaped cross-section rather than a rectangular one, it can be installed later and the vertical members 10 can be passed through it, even if the vertical members 10 have already been installed.

[0039] As shown in Figures 1 and 7, a gap B is formed between the vertical member 10 and the cover base material 30. Because a gap B is formed, even if a screw or other insertion member S is driven into the cover base material 30, the tip of the insertion member S will not reach the vertical member 10.

[0040] As shown in Figure 8, the upper end 31a of the cover base material 30 is sandwiched and fixed by the vertical fixing plate 62a and the inclined fixing plate 63a of the upper fixing bracket 70. Note that in Figure 8, only the middle surface of the cover base material 30 is shown for illustrative purposes.

[0041] Similarly, the lower end 31b of the cover base material 30 is sandwiched and fixed by the vertical fixing plate 62b and the inclined fixing plate 63b of the lower fixing bracket 80.

[0042] The height at which the cover base material 30 is fixed to the inclined fixing plate 63 and the vertical fixing plate 62 by the insertion member S is somewhere at a height that allows it to penetrate both the inclined fixing plate 63 and the vertical fixing plate 62, but it is not specifically determined and is determined by the ceiling heights H1 and H2 from the floor portion 50 to the ceiling portion 40.

[0043] In other words, as shown in Figure 8, when the ceiling height is low, such as H1, the lower end 31b of the cover base material 30 falls due to gravity and is fixed near the point where the vertical fixing plate 62b and the inclined fixing plate 63b of the lower fixing bracket 80 intersect. Similarly, the upper end 31a of the cover base material 30 is fixed near the point where the vertical fixing plate 62a and the inclined fixing plate 63a of the upper fixing bracket 70 intersect.

[0044] On the other hand, if the ceiling height H2 is high and the ceiling height H1 is longer than the length L of the cover base material 30, the lower end 31b of the cover base material 30 will be fixed by gravity near the point where the vertical fixing plate 62b and the inclined fixing plate 63b of the lower fixing bracket 80 intersect. On the other hand, the upper end 31a of the cover base material 30 will be fixed near the tip 62a1 of the inclined fixing plate 63a and the vertical fixing plate 62a.

[0045] Thus, even when ceiling heights H1 and H2 are different, the cover base material 30 can be adapted by the length of the vertical fixing plate 62a and the inclined fixing plate 63a in addition to the length L of the cover base material 30. Therefore, it is not necessary to prepare a cover base material 30 of a different length L each time the ceiling height is different, and the same cover base material 30 can be reused.

[0046] Furthermore, in the case of a ceiling height H2, the lower end 31b of the cover base material 30 was fixed near the point where the vertical fixing plate 62b and the inclined fixing plate 63b of the lower fixing bracket 80 intersect. However, if necessary, the lower end 31b of the cover base material 30 may be fixed near the tips of the vertical fixing plate 62b and the inclined fixing plate 63b, similar to the case of the upper fixing bracket 70.

[0047] (Regarding vertical support member 20) The vertical support members 20 are attached parallel to and adjacent to the vertical members 10. The vertical support members 20 are made of, for example, wood, and are fixed to the vertical members 10 using adhesive or the like. Also, as shown in Figure 1, the cover base material 30 is fixed from both sides at a constant pitch using insertion members S such as screws.

[0048] The length of the vertical support member 20 is formed to be the same as that of the cover base material 30, and the width of the vertical support member 20 is formed to be the same as that of the cover base material 30.

[0049] Since the vertical support members 20 are fixed by being sandwiched between the two sides of the cover base material 30, using the vertical support members 20 prevents the two sides of the cover base material 30 from spreading or narrowing.

[0050] (Regarding the construction procedure) The construction procedure for the interior wall substrate structure 100 will be explained using Figures 4 to 6. First, as shown in Figure 4, the vertical support members 20 are attached to the back side of the vertical members 10 of the inner wall. In this embodiment, adhesive is used for attachment, but the method is not particularly limited as long as it can be attached.

[0051] Next, the positions for fixing the upper fixing bracket 70 and the lower fixing bracket 80 to the ceiling section 40 and the floor section 50 are determined. When determining the positions, the width of the gap B and the length of the width of both sides of the cover base material 30 are taken into consideration. After determining the positions, the upper fixing bracket 70 and the lower fixing bracket 80 are fixed to the ceiling section 40 and the floor section 50 using the insertion member S.

[0052] Next, the cover base material 30 is attached as shown in Figure 5. When attaching it, the inclined fixing plate 63a of the upper fixing bracket 70 is first tilted toward the horizontal fixing plate 61a. Then, the lower end 31b of the cover base material 30 is sandwiched between the inclined fixing plate 63a and the vertical fixing plate 62a of the lower fixing bracket 80, and the upper end 31a of the cover base material 30 is placed against the vertical fixing plate 62a, and the tilted inclined fixing plate 63a is raised toward the cover base material 30. This allows the end portion 30 of the cover base material 30 to be sandwiched between the inclined fixing plates 63a, 63b and the vertical fixing plates 62a, 62b.

[0053] Subsequently, as shown in Figure 6, the cover base material 30 is fixed to the vertical support material 20 by driving the insertion members S into it from both sides at regular intervals. Then, the series of constructions for the interior wall base structure 100 is completed by driving the insertion members S into the cover base material 30 from the inclined fixing plate 63 and fixing it in place.

[0054] Alternatively, although the upper fixing bracket 70 was fixed to the ceiling portion 40 before the cover base material 30 was attached, the upper end 31a of the cover base material 30 may be sandwiched between the inclined fixing plate 63a and the vertical fixing plate 62a of the upper fixing bracket 70 before fixing the upper fixing bracket 70 to the ceiling portion 40.

[0055] Subsequently, as shown in Figure 7, interior wall material I such as gypsum board can be attached to the cover base material 30 from four directions using insertion members S. Figure 7(a) is a cross-sectional view when the interior wall base structure 100 is used at the corner of the interior wall. Figure 7(b) is a cross-sectional view when the interior wall base structure 100 is used at the end of the interior wall. As shown in Figure 7, studs T are used in areas other than the ends and corners. [Explanation of Symbols]
