Description

[Technical Field]

[0001] The present invention relates to a large moving wall that can move along a traveling rail, and in particular to a moving wall that is lightweight and highly rigid with a reduced thickness. [Background technology]

[0002] In multipurpose halls and other facilities, large movable walls (sometimes called "sliding walls" or "moving partitions") are used to divide the space into appropriate sizes. The movable walls are suspended from a running rail via runners and can slide along the rail. In the case of large moving walls, twisting and bending are likely to occur when moving, so it is common to use square pipes in the frame to increase rigidity, but this results in problems such as an increased weight, and as the size of the square pipes increases, the thickness of the moving wall also increases, requiring a large storage space. Furthermore, because the square pipes are connected by welding, there is also the problem that it is difficult to improve dimensional accuracy due to distortion that occurs during welding.

[0003] For example, Patent Document 1 discloses a moving wall whose frame is made of extruded aluminum, thereby reducing its weight. [Prior art documents] [Patent documents]

[0005] However, aluminum extrusions are generally less rigid than steel and are expensive, making them difficult to use for large moving walls.

[0006] In consideration of such problems, the present invention aims to provide a moving wall that is lightweight and highly rigid with a reduced thickness. [Means for solving the problem]

[0007] The moving wall of the present invention is a moving wall that can move along a traveling rail, and the frame of the panel body is rectangular and made up of a plurality of vertical frames extending in the vertical direction on the left and right and a plurality of horizontal frames that are hung between the vertical frames on the left and right, and is reinforced with braces. The vertical frame and the horizontal frame are fixed by a connecting means, and the connecting means includes a front gusset plate arranged on the front side of the butting point between the vertical frame and the horizontal frame, a rear gusset plate arranged on the rear side, and a first rod-shaped member that is hung between the front gusset plate and the rear gusset plate, and both gusset plates are fixed to the vertical frame and the horizontal frame by bolting, and one end of the brace is connected to the first rod-shaped member. It is characterized by: In addition, in a moving wall that can move along a traveling rail, the frame of the panel body is rectangular and is composed of a plurality of vertical frames extending in the vertical direction on the left and right and a plurality of horizontal frames that are hung between the vertical frames on the left and right, and is reinforced with braces. The brace is provided with an intersection metal fitting arranged at the intersection of the braces, and the intersection metal fitting comprises two base plates arranged at a distance on the front and back sides, and four second rod-shaped members that are hung between the two base plates, thereby forming gaps that penetrate in the vertical and horizontal directions, and the other end of the brace is connected to the second rod-shaped members. It is characterized by: [Effects of the Invention]

[0008] In this invention, the frame of the panel body is composed of vertical and horizontal frames and reinforced with braces, so there is no need to use members with a large section modulus for the vertical and horizontal frames, and the thickness of the moving wall can be reduced, making it lightweight while ensuring sufficient rigidity.In addition, the tension of the braces can be adjusted to improve assembly accuracy. In addition, in the present invention, the vertical and horizontal frames are fixed with connecting means (gusset plates or ribs). When gusset plates are used, assembly precision can be improved compared to when the vertical and horizontal frames are fixed by welding. The first rod-shaped member spans between the front and rear gusset plates, and the end of the brace is connected to the first rod-shaped member. This applies tension to the brace at the center of the frame's thickness, making it less likely for the frame to warp or bend. The use of metal crossings prevents the two braces arranged in an X-shape from coming into contact with each other, and also makes it possible to pass the components that make up the moving wall through the gap that occurs between the front and back base plates.

DETAILED DESCRIPTION OF THE INVENTION

[0010] [First embodiment] A first embodiment of the moving wall of the present invention will be described. As shown in Figures 1 to 3, a moving wall 1 is suspended from a traveling rail 3 via a runner 2, and can be slid along the traveling rail 3. Reference numeral 5 in Figures 1 and 2 indicates the ceiling surface.

[0011] The moving wall 1 comprises a panel body 10, two upper and lower pressure contact bodies 20, and a drive mechanism 30. In addition, a plurality of moving walls 1 are connected in the left-right direction to be used as a single large wall, and one moving wall 1 located at the rightmost (or leftmost) end is equipped with a right (or left) pressure contact body 20 in addition to the upper and lower pressure contact bodies 20. Figure 1 shows the case where the pressure contact body 20 is provided on the right side.

[0012] The pressure contact body 20 is stored inside the panel main body 10, more specifically inside the edge member 13, so that it can be freely moved in and out. The worker moves the moving wall 1 to a predetermined position and operates the drive mechanism 30 to press and fix the upper pressure contact body 20 onto the running rail 3 and the lower pressure contact body 20 onto the floor surface 4. The structure of the drive mechanism 30 is not particularly limited and any known one may be used, but for example, when an operator inserts a handle into an operating hole on the surface or side of the panel body 10 and rotates it, the power is transmitted via gears, nuts, etc. to a shaft 31 extending in the vertical and rightward directions, causing the shaft 31 to rotate about its axis, and the pressure contact body 20 connected to the shaft 31 via gears, nuts, etc. moves up and down and left and right. A drive mechanism with a pantograph structure is also known.

[0013] The framework of the panel body 10 is made up of a rectangular frame 40 consisting of vertical frames 41 and horizontal frames 42. The vertical frames 41 are two members, one on the left and one on the right, that extend vertically. Two or more vertical frames 41 may be used. For example, a structure with increased strength may be constructed by arranging square pipes in the left-right direction as the vertical frames 41, or by arranging square pipes and bent plate material in the left-right direction. The horizontal frame 42 is a member that is hung between the left and right vertical frames 41. It is preferable to use square pipes for the vertical frames 41 and horizontal frames 42, but H-shaped steel, C-shaped steel, or rod-shaped members with irregular cross sections may also be used. Plasterboard is placed on the front and back of frame 40 as surface material 11, and glass wool 12 is filled inside. The top, bottom, left, and right edges of frame 40 are surrounded by frame members 13 made of a metal such as aluminum and having a U-shaped cross section. Other materials that can be used as surface material 11 include calcium silicate board and plywood, and a covering material may be attached on top of surface material 11.

[0014] 4(a) and (b), gusset plates 50 are bolted to the butting points of the vertical frames 41 and horizontal frames 42 as connecting means. The front gusset plate 51 is located on the front side of the butting point, and the back gusset plate 52 is located on the back side. In the present invention, the vertical frames 41 and horizontal frames 42 are not fixed by welding, which increases assembly precision. The frame 40 is also reinforced with braces 60. Reinforcement with the braces 60 eliminates the need to use square pipes with a large section modulus for the vertical frames 41 and horizontal frames 42, making it possible to reduce the weight of the moving wall 1. Also, assembly precision can be improved by adjusting the tension of the braces 60. Of the multiple gusset plates 50, the front gusset plate 51 and the back gusset plate 52 of the gusset plates 50 that connect to the brace 60 have extensions 53 that extend inward of the frame 40. A first rod-shaped member 54 is hung between the extensions 53, and the end of the brace 60 is connected to the first rod-shaped member 54. In this way, tension is applied by the brace 60 to the center of the frame 40 in the thickness direction, making it less likely for distortion or bending to occur in the frame 40. Furthermore, as shown in FIG. 3, the tension can be adjusted with turnbuckles 61 attached to the braces 60, thereby improving the assembly accuracy of the frame 40. As another connecting means, for example, as shown in Figure 4(c), a rib 80 may be fixed by welding or bolts to the butt point of the vertical frame 41 and the horizontal frame 42. In this case, it is preferable to fix the rib 80 to the center of the frame 40 in the thickness direction and connect the end of the brace 60 to the rib 80.

[0015] [Second embodiment] Next, a second embodiment of the moving wall will be described, but the same reference numerals will be used to designate parts having the same configuration as the first embodiment, and the description thereof will be omitted. As shown in FIGS. 5 and 6, this embodiment is characterized by the inclusion of an intersection metal fitting 70. The intersection hardware 70 is a member placed at the intersection between the braces 60, and is composed of a base plate 71 and a second rod-shaped member 72.

[0016] The base plates 71 are two plate-like members arranged at a distance from each other on the front and back sides. Four second rod-like members 72 are suspended between the two base plates 71. It is preferable that the base plate 71 be rectangular and the second rod-like members 72 be arranged at the four corners. As described above, one end of the brace 60 is connected to the first rod member 54 and the other end is connected to the second rod member 72 . The use of the intersection hardware 70 prevents the two braces 60 arranged in an X shape from coming into contact with each other. It also makes it possible to pass the members that make up the moving wall 1 through the gap 73 that is created between the front and back base plates 71, 71. For example, if the shaft 31 that moves the pressure contact body 20 up and down is passed through the gap 73, it is possible to prevent interference between the shaft 31 and the brace 60. [Industrial Applicability]

[0017] The present invention provides a moving wall that is thin, lightweight, and highly rigid, and has industrial applicability. [Explanation of symbols]
