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 with high soundproofing performance. [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 running rails via runners, and can slide along the rails. The moving wall is provided with pressure-contacting bodies at the upper and lower ends of the panel body, which protrude outward from the panel body and press against the underside of the running rail and the floor surface, thereby fixing the moving wall and ensuring soundproofing.

[0003] For example, Patent Documents 1 and 2 disclose a structure in which a packing (soundproofing material) is placed between the panel body and the pressure-contact body for the purpose of soundproofing. Furthermore, Patent Document 3 discloses a movable wall in which the mechanism for driving the pressure-contact body is positioned along the frame of the panel body to create a large space within the frame, which is then filled with soundproofing material to improve soundproofing performance.

[0005] To further improve soundproofing performance, it is necessary to suppress the propagation of vibrations caused by sound being received by the panel itself.

[0006] In consideration of such problems, the present invention aims to provide a moving wall with high soundproofing performance. [Means for solving the problem]

[0007] The moving wall of the present invention is a moving wall that can move along a running rail, and the frame of the panel body is a left and right frame extending in the up and down direction. 2 bottles and a plurality of horizontal frames that are hung between the left and right vertical frames, and both the vertical frames and the horizontal frames are made of plate materials, The two vertical frames on the left and right are both made of square pipes, and The thickness of the plate material of the vertical frame is different. The movable wall of the present invention is a movable wall that can move along a running rail, and the frame of the panel body is composed of multiple vertical frames on the left and right that extend in the vertical direction, and multiple horizontal frames that are hung between the left and right vertical frames, and the vertical frames and the horizontal frames are both made of plate material, and the thickness of the plate material of at least two of the multiple horizontal frames is different. Also, The frame is reinforced with a brace, and includes a front gusset plate disposed on the front side of the butting point between the vertical frame and the horizontal frame, and a rear gusset plate disposed on the rear side, both gusset plates are fixed to the vertical frame and the horizontal frame by bolts, and a rod-shaped member is provided that is hung between the front gusset plate and the rear gusset plate, and an end of the brace is connected to the rod-shaped member. . [Effects of the Invention]

[0008] In this invention, both the vertical and horizontal frames are made of plate material, and the thickness of the plate material differs between the left and right vertical frames, between the vertical and horizontal frames, and between the horizontal frames. By changing the thickness of the plate material to change the natural frequency, the soundproofing performance of the moving wall can be improved. By providing a convex portion on the receiving material and having it come into contact with the surfaces of the vertical and horizontal frames through the convex portion, vibrations are less likely to be transmitted to the frame, thereby improving soundproofing performance. If the thicknesses of the plates that make up the vertical and horizontal frames are different, distortion is likely to occur due to the difference in thermal capacity between the two, making it difficult to join the two by welding. Therefore, a connecting method in which the two are bolted together with gusset plates is preferred, and it is even more preferable to reinforce the frame with braces.

DETAILED DESCRIPTION OF THE INVENTION

[0010] An embodiment of the moving wall of the present invention will be described. As shown in Figures 1 and 2, the moving wall 1 is suspended from a traveling rail 3 via a runner 2, and can slide 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] As shown in Figure 3, the skeleton of the panel body 10 is made up of a rectangular frame 40 consisting of vertical frames 41 and horizontal frames 42, and the vertical frames 41 and horizontal frames 42 are made of square pipes processed from sheet metal. In addition to square pipes, rod-shaped members processed into irregular cross sections, such as U-shaped or hat-shaped sheets, may also be used. 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 spans between the left and right vertical frames 41, and is composed of upper and lower horizontal frames 42a located at the top or bottom of the frame 40, and intermediate horizontal frames 42b other than the upper and lower horizontal frames.

[0014] The vertical frame 41 and the horizontal frame 42 are made of plate materials with different thicknesses. The thickness of the board material of the vertical frame 41 and the horizontal frame 42 (upper and lower horizontal frames 42a and middle horizontal frame 42b) may be different as shown in Table 1(a), the thickness of the board material of the left and right vertical frames may be different as shown in Table 1(b), or the thickness of the board material of the vertical frame 41 and the upper and lower horizontal frames 42a and middle horizontal frame 42b may be different as shown in Table 1(c). [Table 1] The natural frequencies can be made different by changing the thickness of the boards of the vertical frames 41 and horizontal frames 42. For example, sound vibrations received by the surface material 11 on the front side of the panel body 10 are transmitted to the frame 40 (vertical frames 41 and horizontal frames 42), and then to the surface material 11 on the back side, vibrating the air in the space behind it and generating sound. In the present invention, for example, the natural frequencies of the vertical frames 41 and horizontal frames 42 can be made different, that is, the frequencies at which they vibrate can be changed, thereby improving the soundproofing performance of the moving wall 1. In particular, the upper and lower horizontal frames 42a and the middle horizontal frame 42b, which are almost the same length, have almost the same natural frequency if their thicknesses are made the same. Therefore, by making their thicknesses different and changing the natural frequencies of the two frames, the soundproofing performance can be further improved.

[0015] 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.

[0016] As shown in FIG. 4, a receiving member 43 is disposed between the surface member 11 and the vertical frame 41 and / or horizontal frame . The support member 43 is a member that supports the surface material 11 by contacting the back surface of the surface material 11 while being screwed to the vertical frame 41 and the horizontal frame 42. The receiving material 43 has protrusions 43a. The protrusions 43a extend in the vertical direction and come into contact with the surfaces of the vertical frames 41 and horizontal frames 42. If the receiving material 43 were in surface contact with the surfaces of the vertical frames 41 and horizontal frames 42, sound vibrations received by the surface material 11 on the front side of the panel main body 10 would be easily transmitted to the frame 40 (the vertical frames 41 and horizontal frames 42). However, by making contact via the protrusions 43a, the vibrations are less likely to be transmitted to the frame 40, thereby improving soundproofing performance.

[0017] As shown in Figure 5, gusset plates 50 are bolted to the butt points of the vertical frame 41 and horizontal frame 42. The front gusset plate 51 is located on the front side of the butt point, and the back gusset plate 52 is located on the back side. When the vertical frame 41 and horizontal frame 42 have different thicknesses as in the present invention, it is difficult to join them by welding, so the method of bolting with gusset plates 50 is effective. Furthermore, by not fixing the vertical frame 41 and horizontal frame 42 by welding, assembly precision can be improved.

[0018] The frame 40 is reinforced with braces 60. By reinforcing with the braces 60, it is no longer necessary 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. In addition, the assembly accuracy can be improved by adjusting the tension of the braces 60. The front gusset plate 51 and the rear gusset plate 52 have extensions 53 that extend inward of the frame 40. A rod-shaped member 54 is hung between the extensions 53, and the end of the brace 60 is connected to the 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.

[0019] In the above embodiment, the vertical frame 41 and the horizontal frame 42 are fixed together by the gusset plate 50, but they may also be fixed together by welding. Furthermore, although the frame 40 is reinforced with the braces 60 in the above embodiment, the braces 60 may not be used. [Industrial Applicability]
