Summary of the Invention

Problems to be Solved by the Invention

[0005] By the way, according to the configuration described in Patent Document 1, inside a steel partition wall applied as a partition for partitioning a living space in a house, a pair of intersecting gypsum boards are arranged, and one of the pair of gypsum boards is placed abutting against the other. However, when the pair of gypsum boards are arranged in a state where a so-called win-lose situation occurs, when attaching or removing one gypsum board to or from the other gypsum board, there has been a problem that smooth attachment or removal cannot be achieved due to interference between the gypsum boards.

[0006] Therefore, an object of the present invention is to provide an inner wall installation method that can avoid interference between gypsum boards and avoid problems in construction.

Means for Solving the Problems

[0007] In response to the above problems, the present invention is an inner wall installation method for installing an inner wall on the indoor side of a building unit, comprising: a first attachment step of attaching a first inner wall panel having a first facing material in contact with a first side surface among an attachment portion having a first side surface, a second side surface intersecting the first side surface, and a corner portion protruding indoors formed in an L shape in plan view by the first side surface and the second side surface; a second attachment step of attaching the attachment portion to which the first inner wall panel is attached to a column constituting the building unit; and a third attachment step of attaching a second inner wall panel having a second facing material to the attachment portion in contact with the second side surface, wherein the first facing material and the second facing material are attached in a state of intersecting via the corner portion.

[0008] Here, the attachment portion has a protruding portion protruding in a direction intersecting the direction in which the first inner wall panel extends, and in the third attachment step, it is desirable to attach the second inner wall panel to the attachment portion in a state of abutting against the indoor side surface among the protruding portions.

[0009] Further, it is desirable that the corner of the first facing material and the corner of the second facing material are arranged in a line contact state at the corner portion. Furthermore, it is desirable that the protruding portion is a portion formed in a plate shape having a thickness of 12 mm or more.

Effect of the Invention

[0010] The inner wall installation method for installing an inner wall on the indoor side of the building unit of the present invention includes a first attachment step of attaching a first inner wall panel having a first facing material to a first side surface so as to be in contact with the attachment portion, a second attachment step of attaching the attachment portion to which the first inner wall panel is attached to a column constituting the building unit, and a third attachment step of attaching a second inner wall panel having a second facing material to the attachment portion so as to be in contact with the second side surface. The first facing material and the second facing material are attached in a state of intersecting via a corner portion.

[0011] For this reason, the first facing material and the second facing material are not arranged in a state of intersecting in a plan view, and it is possible to prevent a so-called winning or losing from occurring between the first facing material and the second facing material. Therefore, it is possible to avoid interference between the gypsum boards and avoid occurrence of construction problems.

[0012] In particular, the attachment portion has a protruding portion that protrudes in a direction intersecting the direction in which the first inner wall panel extends. In the third attachment step, the second inner wall panel is attached to the attachment portion in a state of abutting against the indoor side surface of the protruding portion. Thereby, the second inner wall panel is attached in a state of surface contact with the protruding portion. Therefore, the attachment accuracy of the second inner wall panel to the attachment portion can be improved.

[0013] Also, the corner of the first facing material and the corner of the second facing material are arranged in a line contact state at the corner portion. Thereby, it is possible to avoid interference between the first facing material and the second facing material. Therefore, smooth attachment or removal of the gypsum boards can be realized.

[0014] Furthermore, the protruding portion is a plate-shaped portion having a thickness of 12 mm or more. That is, the second attachment member constituting the attachment portion is formed of a flat plate-shaped member having a thickness of 12 mm or more. Therefore, the fire resistance can be improved.

Mode for Carrying Out the Invention

[0016] Hereinafter, the inner wall installation method according to an embodiment of the present invention will be described with reference to the drawings.

[0017] FIG. 1 is a perspective view of a building unit 1, and FIG. 2 is an exploded perspective view of an inner wall panel. The unit building is a building that can be constructed in a short period of time by transporting the building unit 1 manufactured in advance at a factory to a construction site and assembling it by arranging it horizontally or stacking it vertically at the construction site. The building unit 1 is a box-shaped unit building structure for constructing a unit building, and has a substantially rectangular parallelepiped shape.

[0018] As shown in Fig. 1, the building unit 1 has a unit frame with a box beam structure as a skeleton part inside. The unit frame is mainly composed of four columns 2, four ceiling beams 3, and four floor beams 4.

[0019] The four columns 2 are arranged at the four corners of the unit frame. The four ceiling beams 3 connect the upper ends of the four columns 2 in a rectangular shape to form a ceiling frame. The four floor beams 4 connect the lower ends of the four columns 2 in a rectangular shape to form a floor frame. For example, square steel pipes with a rectangular cross-section are used for the columns 2. For example, steel sections with an inward C-shaped cross-section are used for the ceiling beams 3 and the floor beams 4. A metal joint piece 5 is used for the connection between the columns 2 and the ceiling beams 3 and the floor beams 4. The columns 2 extend in the vertical direction, the ceiling beams 3 and the floor beams 4 extend in the horizontal direction, and the building unit 1 is substantially in the shape of a rectangular parallelepiped.

[0020] Corner columns 22 that extend vertically in parallel with the columns 2 are installed at positions adjacent to the columns 2. A plurality of mounting members 27 (wooden bricks) are provided along the vertical direction on the corner columns 22. Heat insulating materials 40 such as glass wool are installed on the columns 2 or the corner columns 22.

[0021] The ceiling surface of the building unit 1 is configured to be substantially rectangular in plan view by installing a plurality of ceiling joists 11 inside the ceiling frame in parallel so as to span between a pair of opposing ceiling beams 3 and attaching a ceiling surface material to the lower surface. The floor surface of the building unit 1 is configured to be substantially rectangular in plan view by installing a plurality of floor joists 12 inside the floor frame in parallel so as to span between a pair of opposing floor beams 4 and attaching a floor surface material to the upper surface.

[0022] An outer wall 14 is attached to the outside of the building unit 1. Specifically, as shown in Fig. 2, the outer wall 14 is attached to the columns 2 that constitute the building unit 1.

[0023] The main content of the inner wall installation method according to the embodiment is a structure for attaching a pair of inner wall panels (the first inner wall panel 60 and the second inner wall panel 70) around the columns 2 (the corner part).

[0024] The first inner wall panel 60 is a planar member (panel) that constitutes the inner wall and has substantially the same height as the inner wall. The inner wall is configured by arranging a plurality of first inner wall panels 60 side by side horizontally in sequence. The first inner wall panel 60 is a planar member having a first panel frame 61 constituted by a vertical frame 61a and a horizontal frame 61b, and a first facing material 62 attached to the indoor-side surface of the first panel frame 61. The first panel frame 61 is a member having a size and shape adapted to the first facing material 62.

[0025] The first facing material 62 has a first end face 62a that extends vertically adjacent to the vertical frame 61a, a first inner face 62b that is located on the side opposite to the first panel frame and spreads out in a planar manner, and a first corner 62c formed at the portion where the first end face 62a and the first inner face 62b intersect.

[0026] The second inner wall panel 70 is configured to have a second panel frame 71 constituted by a vertical frame 71a and a horizontal frame 71b, and a second facing material 72 attached to the indoor-side surface of the second panel frame 71. The second facing material 72 has a second end face 72a, a second inner face 72b, and a second corner 72c formed at the portion where the first end face 62a and the first inner face 62b intersect. Since the second inner wall panel 70 has the same configuration as the first inner wall panel 60, duplicate explanations are omitted.

[0027] At the inner corner where the column 2 is located, the first inner wall panel 60 and the second inner wall panel 70 are arranged in a state of intersecting via the attachment portion 100. At this time, it is necessary to arrange them so that there is no so-called winning or losing between the first inner wall panel 60 and the second inner wall panel 70.

[0028] FIG. 3 is a diagram for explaining the configuration around the inner corner of the building unit 1, FIG. 4(a) is an exploded perspective view of the attachment portion 100 according to the embodiment, and FIG. 4(b) is a plan view of the attachment portion 100.

[0029] As shown in FIG. 3, the first inner wall panel 60 and the second inner wall panel 70 are attached to the corner intermediate column 22 via the attachment portion 100. Specifically, the first inner wall panel 60 and the second inner wall panel 70 are fixed to the attachment portion 100, and the attachment portion 100 is fixed to the corner intermediate column 22 via the attachment member 27.

[0030] As shown in FIG. 4(a), the attachment portion 100 is configured to include a first attachment member 110 and a second attachment member 120. The first attachment member 110 is a columnar member that is formed in a rectangular shape in plan view and extends in the vertical direction. The first attachment member 110 has four side surfaces, namely, a first side surface 110a, a second side surface 110b, a third side surface 110c, and a fourth side surface 110d.

[0031] The first side surface 110a is the surface with which the first inner wall panel 60 abuts. Specifically, the first panel frame 61 and the first facing material 62 abut against the first side surface 110a and are positioned. The second side surface 110b is the surface with which the second inner wall panel 70 abuts. Specifically, the first panel frame 61 and the first facing material 62 abut against the first side surface 110a and are positioned.

[0032] The first side surface 110a and the second side surface 110b intersect in an orthogonal state, and the portion where the first side surface 110a and the second side surface 110b intersect is defined as a corner portion 110P.

[0033] The second attachment member 120 is a flat plate-shaped member that extends in the vertical direction. The second attachment member 120 is a member that functions as a firestop material, and it is desirable that it has a thickness of 12 mm or more. In addition, if the second attachment member 120 is a member formed in a rectangular shape in plan view, it is desirable that the short side has a length of at least 12 mm or more.

[0034] As shown in FIG. 4(b), the second attachment member 120 is fixed to and integrated with the first attachment member 110 with the second attachment member 120 in contact with the third side surface 110c. In a state where the first attachment member 110 and the second attachment member 120 are integrated, the attachment portion 100 is formed in an L shape in plan view. A part of the second attachment member 120 has a portion protruding from the first attachment member 110, and this portion forms a protruding portion 122. Of the protruding portion 122, the surface on the side where the first attachment member 110 is located is defined as an attachment surface 122a.

[0035] In the method of installing the inner wall, first, the first inner wall panel 60 having the first facing material 62 is attached so as to be in contact with the first side surface 110a. Specifically, as shown in FIG. 5, the vertical frame 61a is fixed to the first attachment member 110 by screws or the like so that the first panel frame 61 and the first facing material 62 abut against the first side surface 110a. When the first inner wall panel 60 is fixed to the first attachment member 110, the first corner portion 62c and the corner portion 110P coincide.

[0036] Next, the attachment portion 100 to which the first inner wall panel 60 is attached is attached to the column 2 constituting the building unit 1. Specifically, as shown in FIG. 5, the first attachment member 110 to which the first inner wall panel 60 is fixed is fixed to the attachment member 27 from the indoor side by screws or the like. When the first inner wall panel 60 is fixed, the first inner side surface 62b of the first facing material 62 is located on the indoor side.

[0037] Finally, the second inner wall panel 70 having the second facing material 72 is attached to the attachment portion 100 so as to be in contact with the second side surface 110b. Specifically, as shown in FIG. 5, with the second inner wall panel 70 in contact with the second side surface 110b and the indoor-side attachment surface 122a of the protruding portion 122, the second inner wall panel 70 is fixed to the second attachment member 120 from the indoor side by screws or the like. When the second inner wall panel 70 is fixed, the second inner side surface 72b of the second facing material 72 is located on the indoor side.

[0038] As shown in Fig. 5, when the first inner wall panel 60 and the second inner wall panel 70, which are a pair of inner wall panels, are fixed to the column 2 via the first mounting member 110, the first facing material 62 (the dotted part in Fig. 5) and the second facing material 72 (the dotted part in Fig. 5) are arranged in a state of intersecting via the corner portion 110P. The first corner 62c and the second corner 72c are arranged in a state of line contact at the corner portion 110P.

[0039] Thus, the inner wall installation method according to the embodiment includes a first mounting step of mounting the first inner wall panel 60 having the first facing material 62 so as to contact the first side surface 110a among the mounting portion 100 having the first side surface 110a, the second side surface 110b intersecting the first side surface 110a, and the corner portion 110P protruding to the indoor side formed in an L shape in plan view by the first side surface 110a and the second side surface 110b; a second mounting step of mounting the mounting portion 100 to which the first inner wall panel 60 is mounted to the column 2 constituting the building unit 1; and a third mounting step of mounting the second inner wall panel 70 having the second facing material 72 to the mounting portion 100 so as to contact the second side surface 110b. The first facing material 62 and the second facing material 72 are mounted in a state of intersecting via the corner portion 110P.

[0040] Thereby, the first facing material 62 and the second facing material 72 are not arranged in a state of intersecting in plan view, and it is possible to prevent a so-called unevenness from occurring between the first facing material 62 and the second facing material 72. Therefore, it is possible to avoid interference between the first facing material 62 and the second facing material 72 and avoid problems in construction.

[0041] Further, the mounting portion 100 has a protruding portion 122 protruding in a direction intersecting the direction in which the first inner wall panel 60 extends, and the second inner wall panel 70 is mounted to the mounting portion 100 in a state of abutting against the indoor side surface of the protruding portion 122. Thereby, the second inner wall panel 70 is mounted in a state of surface contact with the protruding portion 122. Therefore, the mounting accuracy of the second inner wall panel 70 with respect to the mounting portion 100 can be improved.

[0042] In addition, it is desirable that the first corner portion 62c of the first face member 62 and the second corner portion 72c of the second face member 72 be arranged in a line contact state at the corner portion. Thereby, it is possible to avoid the first face member 62 and the second face member 72 from interfering with each other. Therefore, smooth attachment or removal of the first face member 62 and the second face member 72 can be realized.

[0043] Furthermore, the protruding portion 122 is a portion formed in a plate shape having a thickness of 12 mm or more. That is, the second attachment member 120 constituting the attachment portion 100 is formed of a flat plate-like member having a thickness of 12 mm or more. Therefore, the fire resistance can be improved.
