The inner wall upper side support member 3 is fixed via 4.

A construction method of the internal wall structure of the building having this configuration will be described below with reference to FIG.
First, as shown in FIG. 10 (A), ink is drawn out at a place where an internal wall is to be constructed on the floor slab 9 of the building, and a plurality of lower fixed hardware 2 is arranged on the floor slab 9 in an aligned state along the black position. Stop. Thereafter, the inner wall upper side support member 3 is arranged on the ceiling portion in the building so as to extend along the planned location of the inner wall, and the inner wall upper side support member 3 is installed in the building frame. In this example, the inner wall upper side support member 3 is installed on the building frame in the ceiling suspension member 26 extending in the horizontal direction perpendicular to the inner wall upper side support member 3 as shown in FIG. This is done by fixing the support 3 with bolts 27. The ceiling suspension member 26 is supported by the ceiling slab 30 via the hanger 28 (FIG. 9) and the suspension bolt 29.

  Next, as shown in FIG. 10B, the lower side frame member 6 that is a constituent member of the wall base frame assembly 1 is attached to the plurality of lower fixed hardware 2. The upper side frame member 7 positioned above the lower side frame member 6 and the vertical frame member 8 extending between the lower side frame member 6 and the upper side frame member 7 are assembled with each other by a conventional construction method. The wall base frame assembly 1 including these lower side horizontal frame member 6, upper side horizontal frame member 7, and vertical frame member 8 is assembled by assembling by fitting and joining with a tapping screw with a drill.

In this way, as shown in FIG. 10C, the upper side of the assembled wall base frame assembly 1 is fixed to the inner wall upper side support member 3 by the upper fixing hardware 4. Specifically, first, the upper fixed hardware 4 is fixed to the inner wall upper side support member 3 with a bolt 11 through a predetermined gap as shown in FIGS. 2 to 4, and then the upper side of the wall base frame assembly 1 is fixed. Fix to the upper fixed hardware 4 with screws 12.
After that, as shown in FIG. 10D, the wall panel 10 is completed by stretching the face material 5 on both surfaces of the wall base frame assembly 1 by a conventional method (for example, screwing). The lower part of the wall surface panel 10 is housed in a baseboard so that the lower fixed hardware 2 and the lower side frame material 6 are hidden. When a decorative board or the like is pasted on the face material 5 as a finishing process, it is desirable to use a hook-and-loop fastener so that disassembly and reuse described later can be easily performed.

FIG. 11 shows a disassembly procedure of the internal wall structure of the building constructed as shown in FIG.
In this dismantling work, first, the finished decorative board, wallpaper, cloth, etc., which are pasted on the face material 5 of the wall panel 10 are removed. After that, the bolt 11 which attached the upper fixing metal 4 to the inner wall upper side support member 3 is loosened to allow the upper fixing metal 4 to escape upward through the predetermined gap, and the wall panel 10 is lifted. Then, the lower end of the wall panel 10 is pulled out from the lower fixed hardware 2 upward. When the wall panel 10 is heavy, as shown in FIG. 11 (A), the screw 13 (FIGS. 5 to 7) is removed from the lower fixed hardware 2 and FIG. As in (A2) and (A3), the connecting pin 23 for connecting the lower fixed hardware body 21 and the disassembly piece 22 is removed, and the disassembly piece 22 is removed from the lower fixed hardware body 21.
Next, as shown in FIG. 11B, the screws 12 (FIGS. 2 to 4) are removed from the upper fixed hardware 4 to fix the upper fixed hardware 4 to the inner wall upper side support material 3 (FIGS. 2 to 2). 4) is loosened, and the upper fixed hardware 4 is removed from the inner wall upper side support 3.
Next, as shown in FIG. 11C, the wall surface panel 10 released from the restraint by the lower fixed hardware 2 and the upper fixed hardware 4 is pulled out to the front. Thereby, the internal wall structure can be easily disassembled. Then, it accumulates and carries out in the unit of the wall surface panel 10. FIG. If construction is performed in the reverse order of the dismantling described above, the same internal wall structure as in FIG. 1 can be reconstructed. The dismantled wall panel 10 is brought back to the factory, diagnosed and repaired, and then transported to the reconstructed construction site. Also in this case, as the lower fixed hardware 2, the lower fixed hardware main body 21 and the disassembling piece 22 are assembled with the connecting pin 23 as shown in FIG. To do.

FIG. 12 shows another embodiment of the present invention. In the internal wall structure of this embodiment, as shown in the front view of FIG. 12C, any one of the plurality of wall foundation frame assemblies 1 arranged side by side on the same plane is more than the adjacent wall foundation frame assembly 1. Is also formed narrowly and is arranged away from the adjacent wall base frame assembly 1. Here, the wall panel 10 is formed by stretching the face material 5 on one side of the wall base frame assembly 1. However, as shown in the plan view and the front view in FIGS. The face material 5 stretched on the wall base frame assembly 1 is extended to the front surface of the adjacent wall base frame assembly 1.
Moreover, in this embodiment, the face material 5 is used as the decorative board by directly attaching the plate material having a relatively strong strength such as an aluminum panel as the decorative board for the wall finish to the wall base frame assembly 1 as the face material 5. I also use it. That is, the wall base frame assembly 1 is regarded as a wall panel, and a face material 5 serving as a decorative plate is directly stretched on one side thereof. In this case, the face material 5 also serving as a decorative plate is attached to the surface of the vertical frame material 8 of the wall base frame assembly 1 via the surface fasteners 14 and 15 so that the disassembly and reuse can be performed. A configuration in which the lower side of the wall base frame assembly 1 is fixed on the floor slab 9 via the lower fixed hardware 2, and a configuration in which the upper side of the wall base frame assembly 1 is fixed to the inner wall upper side support member 3 through the upper fixed hardware 4. Is the same as in the embodiment of FIG.
In the case of this embodiment, the dismantling is not the state of the wall surface panel 10, but the face material 5 is removed from the wall base frame assembly 1, and the wall base frame assembly 1 is detached alone, and the wall from which the face material 5 has been removed is removed. In the state of the base frame assembly 1, it is used to reconstruct the inner wall.

  As shown in FIG. 13, two types of surface fasteners 14 and 15 are used in combination, and one surface fastener 14 has a large number of engaging bodies 14b implanted on one surface of a base material 14a. The back surface of 14a is attached to the surface of the vertical frame member 8 of the wall base frame assembly 1, for example. The other surface fastener 15 is obtained by implanting a large number of engaged bodies 15b that can be engaged with the engaging bodies 14b on one surface of the base material 15a, and the back surface of the base material 15a is the back surface of the face material 5. It is affixed at a position opposite to the affixing position of the surface fastener 14 on the surface of the vertical frame member 8. By pressing the face material 5 against the surface of the wall base frame assembly 1, the engaging bodies 14 b of the double-sided fasteners 14 and 15 and the engaged body 15 b are engaged with each other, and the face material 5 is placed on the surface of the wall base frame assembly 1. It is pasted. When the surface fasteners 14 and 15 are used in this manner, the face material 5 can be easily attached to the wall base frame assembly 1 and can be easily detached from the wall base frame assembly 1 at the time of disassembly.

According to this internal wall structure, at the time of construction or reconstruction, the separation distance X between the wall base frame assembly 1 formed narrow and the adjacent wall base frame assembly 1 can be finely adjusted, so that columns, walls, etc. can be installed. The error can be absorbed. Moreover, since the board | plate material used as a finishing decorative board lightweight like an aluminum panel is used as the face material 5, the workability improvement of disassembly and reconstruction is attained.
In the case of this embodiment, since the wall surface panel 10 composed of the wall base frame assembly 1 and the face material 5 is light, the lower fixed hardware 2 is used as a mechanism for pulling the wall panel 10 forward as shown in FIG. The structure which can be disassembled can be omitted, and the components can be simplified.

  14 and 15 show still another embodiment of the present invention. In this embodiment, in the internal wall structure of the embodiment of FIG. 12, the wall base frame assembly 1 and the adjacent wall base frame assembly 1 formed narrow as shown in FIG. As shown in FIG. 6, the two wall base frame assemblies 1 and 1 are connected by an anti-sway member 16 made of, for example, a grooved steel so that the distance between them can be adjusted. Specifically, as shown in FIG. 15 (A), through-holes 17 penetrating in the horizontal direction along the surfaces of the wall base frame assemblies 1 are provided in the vertical frame members 8 of the adjacent wall base frame assemblies 1 and 1. As shown in FIG. 15B, the steadying member 16 is inserted into the insertion holes 17 across the adjacent wall base frame assemblies 1 and 1.

  As described above, when the adjacent wall base frame assemblies 1 and 1 are connected by the steadying member 16, the separation distance X between the adjacent wall base frame assemblies 1 and 1 can be adjusted, and the two wall base frame assemblies 1 can be adjusted. The accuracy can be ensured so that the surfaces of the two are aligned on the same plane.
