Description

  The present invention relates to a moving wall suspended from a ceiling rail and a frame structure serving as a framework of the moving wall.

  The moving wall is constructed so as to be able to move by being suspended from the ceiling rail. For this purpose, a plurality of moving walls are arranged in a predetermined place to form a partition that partitions a large space. And when it is unnecessary, it is stored in a storage section provided at one corner of the room, and the partition can be easily stored. In this way, the moving wall is provided with a suspension wheel at the upper end so that the installation location can be changed, and the upper and lower ends are provided with pressure contact members that can be fixed in pressure contact with the ceiling rail and the floor surface.

  A frame (frame body) that constitutes a conventional moving wall has a structure in which both vertical rails, upper rails, and lower rails are framed, and intermediate rails that serve as reinforcements are provided between the rails as necessary. The crosspieces are welded to each other or screwed together to be assembled as a frame, and panels are bonded to both sides of the frame to form a moving wall. Assembling work of the frame is not easy. Therefore, the number of assembling steps is increased, and it is not easy to accurately assemble a large rectangular frame.

  The moving wall is fixed by adhering the panel to the frame, and the frame and the panel are completely integrated. Unlike a general fixed partition device, the moving wall has a different installation location, so that the panel is bonded so that it does not come off the frame, and edges are attached to the four sides of the panel. For example, when a large earthquake occurs and shakes, the panel is fixed to the frame because it is very dangerous if the panel falls off the frame.

  The “moving wall suspension structure” according to Japanese Patent Application Laid-Open No. 2000-310084 is a moving wall suspension structure in which a suspension bolt is loosened so that it does not fall off a suspension vehicle and the movement wall does not fall down. Therefore, a socket with a screw hole is attached to the upper end of the moving wall, and the washer is fitted to the suspension bolt with a flat surface on the side so as not to rotate, and the suspension bolt is screwed into the screw hole of the socket, The washer is placed on the upper end of the socket and locked to a locking piece provided on the upper end.

As described above, it is important to prevent the suspension bolt from loosening and the moving wall from coming off the suspension vehicle, but it is not always best to firmly fix the panel of the moving wall to the frame. A frame in which the vertical beam, the upper beam, the lower beam, and the intermediate beam are connected to each other by welding is configured as an integrated rigid body. Then, if the panel is fixed to the rigid frame, a larger rigid body is obtained. Therefore, when an earthquake occurs, the large moving walls swing together and are extremely dangerous.
“Hanging structure of moving wall” according to JP 2000-310084 A

  Thus, the moving wall has the above-mentioned problems. The problems to be solved by the present invention are these problems, and it is possible to easily and accurately assemble a frame at low cost, and to provide a moving wall that is safe against earthquake shaking.

  The moving wall according to the present invention is configured by attaching a panel to a frame, and the frame has a structure in which an upper beam and a lower beam are connected to both vertical beams, and a reinforcing intermediate beam is mounted if necessary. ing. By the way, although the frame structure as a frame is the same as that of the prior art, in the present invention, each frame is connected via a connecting member instead of a welding or screwing structure in configuring the frame. The connecting member has a substantially U-shape and has a back plate and both side plates.

  The back plate is screwed to the vertical beam, and the side plate is fitted and connected to the upper beam, the lower beam, and the reinforcing intermediate beam to form a frame. Here, a small convex portion protrudes from the outer surface of the side plate of the connecting member, a locking hole is provided in one of the upper rail, the lower rail, and the intermediate rail, and the side plate extends to the upper rail, the lower rail, and the intermediate rail. Simultaneously with the fitting, the convex portion engages with the locking hole. As a result, the side plate is fixed so as not to be detached from the upper rail, the lower rail, and the intermediate rail. However, it is not a rigid body that is completely integrated like a frame in which the bars are connected by welding.

  As described above, the frame according to the present invention is configured by connecting the vertical beam, the upper beam, the lower beam, and the intermediate beam via the connecting member, and the panels are attached to both surfaces of the frame. The panel can be attached in the same manner as in the past, and the panel can be attached by hooking the tabs projecting on both sides of the connecting member. The claw formed on the connecting member protrudes on both sides of the frame, and the panel can be hooked on the claw.

  When the panel is hooked and attached to the claw, an elongated slit groove is provided on the fastening piece formed by bending the panel surface material, and an engagement hole is provided above the slit groove at a predetermined interval. doing. Therefore, when the panel is hooked on the claw, the upper end of the slit groove is locked to the support portion of the L-shaped claw, and the engaging hole is locked to the step of the convex curved surface formed on the inner surface of the upright portion.

  An upper pressure contact member that presses against the ceiling rail is provided at the upper end of the frame of the moving wall, and a lower pressure contact member that presses against the floor surface is provided at the lower end of the frame. The upper and lower pressure contact members are press contact device operation units (jacks) mounted inside the frame. ) And a shaft. In addition, a spring is interposed in the middle of the shaft, and the frame can move up and down by the spring extending and contracting in a state where the upper and lower pressure contact members are in pressure contact with the ceiling rail and the floor surface.

  The frame of the moving wall according to the present invention forms a frame body by connecting the vertical beam, the upper beam, the lower beam, and the middle beam via a connecting member. That is, it is not a welded or screwed structure as in the prior art, and as a result, the assembly work of the frame can be performed in a short time. That is, the connecting member is simply assembled by screwing the back plate of the connecting member to the vertical beam and fitting both side plates of the connecting member to the upper beam, the lower beam, and the intermediate beam, and is configured as an accurate rectangular frame. .

  And if a nail | claw protrudes in the both sides of a connection member, a panel can be hooked and attached using this nail | claw. Therefore, since the frame can be suspended from the suspension car in advance and the panel can be hooked and attached to the suspended frame, the installation work of the moving wall is convenient and easy. Further, since the transfer work from the factory to the site is facilitated, it is not necessary to perform a dangerous work such as heavy object transfer.

  Furthermore, when transporting an integrated moving wall with a panel attached to the frame, the panel surface may be scratched during transport, but the panel is transported separately to the frame suspended beforehand. The risk of scratching the panel surface is reduced as much as possible. On the other hand, it is possible to assemble a frame that is framed via a connecting member or directly at the site.

  On the other hand, the vertical beam, the upper beam, the lower beam, and the intermediate beam are connected via a connecting member to form a frame. For this reason, the frame is different from the frame formed by welding, and is not an integrated rigid body. Absent. Therefore, when shaking in the event of an earthquake, a large stress concentration does not occur at the connecting parts of the crosspieces of the frame. Furthermore, if the panel is hooked and attached to the claw provided on the connecting member, the shaking of the earthquake can be released between the frame and the panel, not the rigid body in which the frame and the panel are integrated. However, the panel does not come off the tab.

  FIG. 1 shows an embodiment in which a large room space is partitioned by three moving walls 1a, 1b and 1c. These three movable walls 1a, 1b, and 1c can be suspended and moved by a suspension vehicle (not shown) that travels on the ceiling rail. When the movable walls 1a, 1b, and 1c are arranged at predetermined positions, An upper press contact member and a lower press contact member attached to the upper end and the lower end protrude and are fixed. In addition to the upper and lower pressure contact members, the movable wall 1c is provided with a side pressure contact member, and the wall wall attached to the wall surface is pressed by projecting the side pressure contact member so that the movable wall 1c moves backward. Each moving wall 1a, 1b, 1c can contact | abut mutually without gap.

  FIG. 2 is a longitudinal sectional view in which the moving wall 1 is suspended from the ceiling rail 2 via a suspension wheel 3, and FIG. 3 is a transverse sectional view of the moving walls 1a, 1b, and 1c. The movable wall 1 is configured by attaching panels 4 and 4 to both sides of a framed frame, and glass wool is accommodated as a filler 5 between the panels 4 and 4. Further, the panel 4 is constituted by sticking a metal surface material 7 with a gypsum board 6 as a backing material.

  The suspension vehicle 3 rotatably supports two horizontal wheels 8 and 8 at a predetermined interval, and the outer peripheral portions of the horizontal wheels 8 and 8 are connected to traveling pieces 9 and 9 provided on the ceiling rail 2. It is listed. Accordingly, when the horizontal wheels 8 and 8 are rotated, the suspension vehicle 3 travels on the ceiling rail 2 and the moving wall 1 can move. However, the structure of the moving wall 1 and the suspension vehicle 3 shown in the figure is only one specific example, and is not limited thereto.

  In the figure, reference numeral 10 denotes an upper pressure contact member, and 11 denotes a lower pressure contact member. If the upper pressure contact member 10 protrudes and rises, it comes into pressure contact with the support piece 12 of the ceiling rail 2, and the lower pressure contact member 11 protrudes and falls. Press contact with the floor 13. The upper and lower pressure contact members 10 and 11 are pressed against the support piece 12 and the floor surface 13 so that the movable wall 1 is fixed at a predetermined position. Then, a side pressing member 14 is attached to the side end of the moving wall 1c in FIG. 3. If the side pressing member 14 protrudes and abuts against the wall rail 15, the moving wall 1c moves backward to move each side. The gap between the walls 1a, 1b, and 1c can be eliminated, and the side end of the moving wall 1a can be brought into contact with the wall rail 15 without any gap.

  FIG. 4 is a specific example of the frame 16 constituting the moving wall 1. (A) is a front view, (b) is a side view, (c) is a plan view, (d) is a BB sectional view, and (e) is an AA sectional view. The frame 16 is framed by two vertical bars 17a and 17b, an upper bar 18 and a lower bar 19, and two intermediate bars 20 and 20 are provided between the upper and lower bars 18 and 19. The vertical bars 17a and 17b are connected to the upper and lower bars 18 and 19 and the intermediate bars 20 and 20 by connecting members 21, 21.

  A jack 22 is attached to the lower intermediate rail 20 inside the frame 16, and the upper pressure contact member 10 and the lower pressure contact member 11 can be moved up and down by operating the jack 22. Similarly, the side pressing member 14 can be protruded. A shaft 23 extends upward from the jack 22 and is connected to the upper pressure contact member 10, and a shaft 24 extends downward to be connected to the lower pressure contact member 11. Further, spring portions 25 and 25 accommodating coil springs are interposed in the middle of the shaft 23 and the shaft 24.

  Therefore, when the upper pressure contact member 10 is in pressure contact with the support piece 12 of the ceiling rail and when the lower pressure contact member 11 is in pressure contact with the floor surface 13, the coil springs accommodated in the spring portions 25, 25 are compressed. For this purpose, the frame 16 restrained by the ceiling rail 2 and the floor surface 13 via the upper and lower pressure contact members 10 and 11, and the movable wall 1 with the panels 4 and 4 attached to the frame 16 are vertically moved within a certain range. It is in a state where it can move. Therefore, since the movable wall 1 can move up and down when an earthquake occurs, a large load does not act on the ceiling rail 2 and the floor surface 13.

  FIG. 5 is an embodiment showing the connecting member 21. In the present invention, this connecting member 21 can be used to easily connect the vertical bars 17a, 17b to the upper bar 18, the lower bar 19, and the intermediate bars 20, 20. That is, the frame 16 in FIG. 4 is a frame 16 configured by connecting the crosspieces via the connecting members 21, 21... Without being welded.

  The connecting member 21 is substantially U-shaped with side plates 31, 31 provided on both sides of the back plate 30, and has holes 33, 33 for screwing at the center upper and lower ends of the back plate 30. Protrudes from the outer surface. The connecting member 21 is formed by bending a punched rectangular metal plate into a U-shape, and the protruding portion 34 protruding from the side plate 31 can be formed by pressing as shown in the AA cross-sectional enlarged view.

  On the other hand, FIG. 6 shows another embodiment showing the connecting member 21. As in the connecting member 21 shown in FIG. 5, the back plate 30 is substantially U-shaped with side plates 31 and 31 provided on both sides. The upper and lower ends of the center of the plate 30 have holes 33 and 33 for screwing, and the side plates 31 and 31 have protrusions 34 and 34 projecting from the outer surface. The connecting member 21 is provided with claws 29 on both sides. The claw 29 is L-shaped, the inner side surface 32 forms a smooth convex curved surface, and a step is provided by notching the top lower side of the convex curved surface.

  FIG. 7 shows a specific example of the panel 4, and the panel 4 shows a form in which the panel 4 is hooked and attached to a claw 29 provided on the connecting member 21. (A) of the figure is a front view, (b) is a rear view, (c) is an AA sectional view, and (d) is a BB sectional view. As shown in the figure, the panel 4 is constructed by using a gypsum board 6 as a backing material, and a surface material 7 adhered thereto, and the surface material 7 is bent to form fastening pieces 26 and 26 on both sides. Yes.

  The fastening pieces 26, 26 are provided with elongated slit grooves 27, 27... Extending in the vertical direction, and the engagement holes 28 are provided above the slit grooves 27, 27. , 28... Here, the shape of the engagement hole 28 is not limited to a circle, and any shape may be used as long as the lower part forms a smooth arc.

  FIG. 8 shows a connection structure in which the vertical beam 17a and the intermediate beam 20 are connected via the connection member 21, and shows an enlarged view of part (a) in the BB sectional view of FIG. The intermediate crosspiece 20 is a long material having a substantially U-shaped cross section, and the side plate 31 of the connecting member 21 is fitted to the intermediate crosspiece 20 and the protruding portion 34 protruding to the outer surface is engaged with a hole provided in the intermediate crosspiece 20. Then, the screw 35 inserted through the holes 33, 33 of the back plate 30 is screwed into the screw hole of the vertical beam 17a and fixed. As shown in the drawing, both side plates 31, 31 are fitted to the two intermediate bars 20, 20, and the protrusions 34 are connected to the holes formed in the intermediate bars 20, 20. Airtight rubber 36, 36 is attached to the vertical rail 17a.

  FIG. 9 shows a connection structure between the vertical beam 17b on the opposite side and the intermediate beams 20 and 20, and shows an enlarged view of part (b) in the BB sectional view of FIG. The connection structure is the same as in FIG. 8, but the cross-sectional shape of the vertical beam 17b is slightly different from that of the vertical beam 17a. That is, the vertical rail 17b forms a concave portion 37 with which the airtight rubbers 36, 36 of the vertical rail 17a are engaged so that the side ends of the adjacent moving walls 1a, 1b abut against each other without any gap.

  In this way, the two intermediate bars 20 and 20 that are parallel to each other are connected to each other via the connecting members 21 and the vertical bars 17a and 17b disposed at both ends thereof. The claws 29 and 29 are located between 17a and 17b, and the claws 29 and 29 protrude from the outer surfaces of the intermediate bars 20 and 20. 8 and 9, the connection structure between the intermediate beam 20 and the vertical beam 17 has been described. However, the connection structure between the upper beam 18 and the vertical beam 17 and the connection structure between the lower beam 19 and the vertical beam 17 are the same. .

  FIG. 10 shows a case where the connecting member 21 is attached to the vertical beam 17 and the side plate 31 of the connecting member 21 is fitted to the intermediate beam 20. The side plate 31 is attached to the intermediate beam 20 made of a long material having a substantially U-shaped cross section. The projections 34 that are fitted and projecting on the outer surface of the side plate 31 are connected so as not to be detached by engaging with the holes 38 of the intermediate rail 20. The convex portion 34 has a shape that is inclined so as to be easily engaged with the hole 38 and is locked so as not to be detached once it is engaged with the hole 38.

  FIG. 11 shows the case where the claw 29 is engaged with the slit groove 27 and the engagement hole 28 of the fastening piece 26 provided at the side edge of the panel. By engaging the L-shaped claw 29 provided on the connecting member 21 with the slit groove 27, the upper end 40 of the slit groove 27 is locked to the support portion 39 of the claw 29, and the fastening piece 26 is supported on the claw 29. Is done. The inner side surface 32 of the upright portion 41 forms a smooth convex curved surface, and a step 42 is formed by notching the lower side of the top of the curved surface.

  Therefore, the tip of the convex portion is fitted in the engagement hole 28 and the step 42 is engaged with or close to the lower inner peripheral surface 43 of the engagement hole 28. Therefore, when the fastening piece 26 is going to rise, the lower inner peripheral surface 43 is locked to the step 42 to prevent the fastening piece 26 from rising. That is, the panel 4 is lifted so that it does not come off the claw 29. For example, when an earthquake occurs and the movable wall 1 swings up and down, the panel 4 in a state of being locked to the claws 29, 29. By stopping, it does not fall off from the claws 29, 29.

  The vertical movement of the moving wall 1 is caused by the fact that the shafts 23 and 24 connected to the upper and lower pressure contact members 18 and 19 provided on the frame 16 have spring portions 25 and 25 that house coil springs. As the coil spring expands and contracts, the vertical shaking of the moving wall 1 is alleviated. Therefore, the panels 4 and 4 locked to the claws 29, 29... Of the frame 16 are difficult to come off. Further, when the panel 4 is lifted with the moving wall 1 suspended, the lower inner peripheral surface 43 of the engagement hole 28 cannot be locked to the step 42 and lifted. Moreover, if the panel 4 is further lifted, the coil spring accommodated in the spring portion 25 of the pressure welding device is compressed and the frame 16 is simultaneously raised.

  Therefore, when removing the panel 4 from the frame 16, the moving wall 1 is separated from the suspension wheel 3 and is brought down on the floor surface. That is, if the movable wall 1 is tilted to the floor, the lower inner peripheral surface 43 of the engagement hole 28 forming an arc can be removed from the step 42 formed on the tab 29 when the panel 4 is pressed from the lower end. That is, when the large inner force 43 acts on the lower inner peripheral surface 43 that is in contact with both corners of the step 42, the step 42 is detached. In this case, even if the moving wall 1 that has fallen to the floor surface is pressed against the lower end of the panel, the coil spring does not deform and the frame 16 does not move.

  The moving wall of the present invention is not a completely integrated rigid body because the frame has a structure in which the frame is formed via a connecting member. Therefore, when an earthquake occurs, the vibration can be absorbed to some extent at the connecting portions of the crosspieces, and no large stress is generated at the connecting portions. In particular, since the spring force is applied to the upper and lower pressure contact members of the frame, the panel does not fall off even if the panel is hooked and attached to the claw formed on the connecting member.
