Abstract

To provide a blocking member in which in a case of changing a bilayer specification of a partition 1 in which a pair of front and rear panel bodies 2 are incorporated therein into a monolayer specification in which one panel body 2 is incorporated, an upper blocking member 21 blocking an upper fitting groove part 10 not incorporated with the panel body 2 does not unintentionally fall.SOLUTION: An upper blocking member 21 includes a blocking piece part 21a, and first and second leg piece parts 21b, 21c. The upper blocking member has a blade shape in which a distal end of the second leg piece part 21c is formed with a folding piece part 21e. Changing into an incorporation posture is achieved by performing fitting movement for correcting inclination of the upper blocking member 21 in a pre-incorporation posture in an inclined state in which the folding piece part 21e is precedingly fitted to an upper fitting groove part 10, in a manner that an inclined surface part 10ca applies resistance to movement of the folding piece part 21e.SELECTED DRAWING: Figure 11

Description

[Technical Field]

[0001] The present invention relates to a sealing material and a sealing method for a fitting groove in a partition that separates an indoor space. [Background technology]

[0002] Today, partitions incorporating panels are used to separate interior spaces into front and rear sections. Some such partitions are configured so that a frame is attached to a rail (a structural member) installed on the ceiling or floor, and the panel is fitted into a U-shaped fitting groove formed in the frame. When using a partition of this configuration to form an office (workroom) such as a meeting room, the panel may be made multi-layered (two panels) rather than single-layered (one panel) to improve soundproofing, heat insulation, and other performance. When configuring such a multi-layer partition, the frame is formed with a pair of fitting grooves, one at the front and one at the back, for attaching two panel bodies. When forming a partition using a frame material with mating grooves formed at the front and back, the frame material can be used not only as a multi-layer type in which two panel bodies are incorporated, but also as a single-layer type in which a single panel body is incorporated.To accommodate this, the mating groove on the side where the panel body is not incorporated is sealed with a sealing material (see, for example, Patent Document 1). [Prior art documents] [Patent documents]

[0003] [Patent Document 1] Patent No. 6560008 Summary of the Invention [Problem to be solved by the invention]

[0004] However, the conventional sealing materials described above are configured so that the leg pieces formed on the sealing material are simply inserted into the mating grooves from above and below to engage with the frame material. This not only requires a forceful insertion operation from the beginning, but also means that when such sealing materials are inserted into mating grooves formed in a frame material, such as an upper frame material installed on the ceiling side, it is anticipated that some of the sealing materials may inadvertently come out of the mating grooves when subjected to vibrations in a state where their engagement with the frame material has loosened due to deterioration over time, etc. These are the problems that the present invention aims to solve. [Means for solving the problem]

[0005] The present invention has been made in view of the above-mentioned circumstances and with the aim of solving these problems, and the invention of claim 1 is a partition for dividing an interior space, which comprises a multi-layer frame material in which a pair of fitting grooves into which a panel body is fitted is arranged at the front and rear, and the front and rear fitting grooves are configured in a U shape by a groove bottom piece and first and second groove side pieces on the outside and inside in the front-to-rear direction, and the frame material is of a single layer specification in which a panel body is fitted into one of the pair of fitting grooves, but the other fitting groove is closed with a closing material. The sealing material is a sealing material for a fitting groove in a partition, characterized in that it is sword-shaped and comprises a sealing piece that seals the opening edge of the fitting groove, a first leg piece that extends from the outer front-to-rear edge of the sealing piece toward the groove bottom piece in a state where it is closely opposed to the first groove side piece and engages with the first groove side piece, a second leg piece that extends from the middle front-to-rear part of the sealing piece toward the groove bottom piece in a state where it is spaced apart from the second groove side piece, and a bent piece that bends from the tip edge of the second leg piece toward the second groove side piece and whose tip edge engages with the second groove side piece. The invention of claim 2 is a sealing material for a fitting groove in a partition described in claim 1, characterized in that in the pre-installation position before the sealing piece is fitted into the fitting groove and assumes an installation position in which it blocks the opening edge, the first and second leg pieces fit into the fitting groove in an inclined state with the folded piece fitted before the first leg piece, and by forcibly pushing in one end edge side in the front-to-rear direction of the fitting piece in the fitted pre-installation position, the sealing piece is further fitted in while correcting the inclined state, transforming into the installation position. The invention of claim 3 is a sealing material for a fitting groove portion in a partition described in claim 2, characterized in that the frame material is provided with a correction means for correcting the inclination of the sealing material during the process of transformation from the pre-installation position to the installed position. The invention of claim 4 is a sealing material for the fitting groove in the partition described in claim 3, characterized in that the second groove side piece has an inclined surface portion that is inclined toward the first groove side piece as it approaches the groove bottom piece, and the inclined surface portion constitutes a correction means that corrects the inclined state by the tip edge of the second leg piece passing over the mountain in the process of transforming from the pre-mounting position to the mounted position. The invention of claim 5 is a sealing material for a fitting groove in a partition described in claim 3, characterized in that a third leg piece shorter than the first and second leg pieces is formed at the other front-to-rear end edge of the sealing piece, and a contact receiving portion is formed at the tip edge of the second groove side piece against which the tip edge of the third leg piece abuts in the pre-installation position, and the contact receiving portion is configured as a correction means for correcting the inclined state by the tip edge of the third leg piece moving the contact receiving portion toward the groove opening edge during the process of transforming the sealing material from the pre-installation position to the installed position. The invention of claim 6 is a sealing material for a fitting groove in a partition as described in claim 5, characterized in that the abutment receiving portion is a connecting piece portion that connects the tip edge portions of the front and rear second groove side piece portions. The invention of claim 7 is a sealing material for a fitting groove portion in a partition according to claim 1, characterized in that the sealing material is attached to the upper frame material. The invention of claim 8 is a partition for dividing an interior space, comprising a multi-layer frame material in which a pair of fitting grooves into which a panel body is fitted is arranged at the front and rear, and the front and rear fitting grooves are configured in a U-shape by a groove bottom piece and first and second groove side pieces on the outside and inside in the front-rear direction, in which the frame material is configured to have a single-layer specification in which one of the pair of fitting grooves is fitted with a panel body and the other fitting groove is closed with a closing material, the closing material comprising a closing piece that closes the open end edge of the fitting groove, a first leg piece that extends from the outside end edge of the closing piece in the front-rear direction towards the groove bottom piece while facing closely to the first groove side piece and whose tip edge engages with the first groove side piece, and a groove that closes the open end edge of the fitting groove from the middle part of the closing piece at a distance from the second groove side piece The sealing material is sword-shaped and has a second leg piece extending toward the bottom piece, and a bent piece bent from the tip edge of the second leg piece toward the second groove side piece, with the tip edge engaging with the second groove side piece.The process of fitting the sealing material into the fitting groove involves the following steps being carried out in sequence: a pre-fitting position in which the first and second leg pieces are fitted into the fitting groove in an inclined state with the other front-to-rear end edge of the sealing piece close to the opening end edge of the fitting groove; a forced pushing step in which the one front-to-rear end edge of the inclined sealing piece is forcibly pushed in to further fit the sealing material in a state in which the inclined state of the sealing material is corrected; and a process of fitting the sealing material until it reaches an fitted position in which the sealing piece blocks the opening end edge. The invention of claim 9 is a method for sealing a fitting groove portion in a partition described in claim 8, characterized in that the frame material is provided with a correction means for correcting the inclination of the sealing material that is inclined in the pre-installation position, the process of fitting the sealing material into the pre-assembly position is a light push before the sealing material is corrected by the correction means, and the forced pushing process is a strong push to fit the sealing material with rotation by the correction means, thereby transforming the sealing material into the assembly position. [Effects of the Invention]

[0006] By adopting the invention of claim 1 or 8, when a partition with a multi-layer specification in which a panel body is inserted from the front to the back is changed to a single-layer specification, the closing material for closing the one fitting groove portion where the panel body is not inserted comprises a closing piece portion for closing the opening edge portion of the fitting groove portion, a first leg piece portion that extends from the outer edge portion of the closing piece portion in the front-rear direction toward the groove bottom piece portion while being closely opposed to the first groove side piece and engaging with the first groove side piece, a second leg piece portion that extends from the middle portion of the closing piece portion in the front-rear direction toward the groove bottom piece portion while being spaced apart from the second groove side piece, and the second leg piece portion The sealing material is shaped like a sword and is bent from the tip edge of the leg piece toward the second groove side piece, and has a bent piece whose tip edge engages with the second groove side piece.As a result, when the sealing material is initially inserted into the fitting groove, it is inserted in an inclined state, and then the inclined sealing material can be inserted and fitted in an assembled position by rotating it to correct the inclination.This not only makes it easier to insert and fit the sealing material, but also reliably prevents the inserted and fitted sealing material from loosening or falling off inadvertently. By adopting the invention of claim 2 or 9, when fitting and assembling the sealing material into the fitting groove, the sealing material can be brought into the pre-fitting position by lightly pushing it in while it is in an inclined position with the bent piece portion first fitted into the fitting groove, and then the edge portion on one end side in the front-to-rear direction, which forms the apex of the inclination of the sealing material in the pre-fitting position, can be forcibly pushed in strongly to correct the inclination, thereby improving workability. By adopting the invention of claim 3, in the process of transforming the blocking material from the pre-installation position to the installation position, the inclination of the blocking material is corrected by the correction means, and as a result, when the blocking material in the inclined pre-installation position is forcibly pushed in to change to the installation position, the inclination can be corrected unintentionally, thereby ensuring the transformation to the installation position. By adopting the invention of claim 4, the inclined surface portion formed on the second groove side piece portion is configured as a correction means, so that the posture of the inclined blocking material can be corrected with a simple configuration without the need to make the configuration of the frame material particularly complex. By adopting the invention of claim 5, the correction means is configured so that the third leg piece formed on the sealing material moves while in contact with the abutment receiving portion provided on the second groove side piece, so that the posture of the inclined sealing material can be corrected with a simple configuration without the need to make the configuration of the frame material and sealing material particularly complex. By adopting the invention of claim 6, the abutment receiving portion becomes a connecting piece portion with a reinforcing function by connecting the front and rear second leg piece portions together, so that the connecting piece portion can also be used as the abutment receiving portion, which contributes to simplifying the structure. By adopting the invention of claim 7, the sealing material that is inserted and fitted with tilt correction is for the upper fitting groove portion, so it is possible to prevent the sealing material from loosening and falling off inadvertently.

[0008] First Embodiment First, a first embodiment of the present invention will be described with reference to the drawings. In the drawings, reference numeral 1 denotes a partition (partition panel). The partition 1 of this embodiment is installed in an indoor space to separate a work room (work space) R, such as a meeting room or an office. For this reason, in order to prevent sounds (such as voices during a meeting) generated in the work room R from leaking outside the work room S, the partition 1 incorporates two multi-layer (two-layer) panel bodies 2 (which may be opaque plates, but can also be made of transparent or translucent plates such as acrylic plates or glass plates) as shown in Figures 2 to 6, and is provided as a multi-layer partition with excellent performance in various areas, such as soundproofing (sound insulation) and thermal insulation. The present invention is implemented when the multi-layer partition 1 is used as a single-layer partition with only one panel body 2 attached, as shown in FIGS. Incidentally, the partition 1 in this embodiment is described as a flat plate that divides the indoor space into front and back into the workroom R and the outside workroom S, but it goes without saying that it can also be implemented as an L-shaped or square-shaped partition, in which case the indoor space will be divided not only front and back but also left and right.As such, the definition of ``front and back'' when dividing the indoor space front and back takes into account the case where the partition 1 divides the indoor space left and right, and is defined as the front and back when the panel body 2 that constitutes the partition 1 is viewed from the front, without being bound by the direction in which the partition 1 divides the room.

[0009] Regarding the partition 1, first, a multi-layer specification (multi-layer type) in which a pair of panel bodies 2 are attached to the front and rear will be described. In this structure, upper and lower frame members 5 and 6 are attached to upper and lower rail members 3 and 4, which are main body members provided on the ceiling surface H and floor surface F, respectively, and a vertical frame member 7 (upright) is attached to a vertical rail member 15, which is a main body member provided on the wall surface W.The panel body 2 is inserted and assembled into the rectangular space surrounded by these upper and lower frame members 5 and 6 and the vertical frame member 7, thereby forming a flat partition 1 in the left-right direction.

[0010] The upper and lower rail members 3, 4 are U-shaped with an opening on the inside in the vertical direction, with spanning pieces 3a, 4a fixed to the ceiling surface H and floor surface F with screws 3c, 4c, and both leg pieces 3b, 4b extending inward in the vertical direction from the ceiling surface H and floor surface F. The upper and lower frame members 5, 6 are assembled with the front and rear leg pieces 5b, 6b fitted onto the front and rear leg pieces 3b, 4b of the upper and lower rail members 3, 4 configured in this way, and the upper and lower frame members 5, 6 are U-shaped with an opening on the outside in the vertical direction by including spanning pieces 5a, 6a and front and rear leg pieces 5b, 6b, and are configured so that their positions can be adjusted in the vertical direction by adjusting the upper and lower adjusters 8, 9 provided between the spanning pieces 3a, 4a of the upper and lower rail members 3, 4.

[0011] The outer end portion of the spanning piece 5a of the upper frame material 5 in the fore-and-aft direction forms the groove bottom piece 10a of the fore-and-aft upper mating groove portion 10 described below, and a leg piece 5b extends upward from the middle portion of the groove bottom piece 10a in the fore-and-aft direction.The leg piece 5b is fixed to the leg piece 3b of the upper rail material 3 via a screw 5c together with the upper pushing edge 12 as described below, so that the upper frame material 5 can be attached and fixed to the upper rail material 3. Furthermore, a second groove side piece 10c, which is located on the inner side of the groove bottom piece 10a in the fore-and-aft direction, extends downward from the spanning piece 5a of the upper frame material 5 from the inner end of the groove bottom piece 10a in the fore-and-aft direction, thereby forming an L-shape between the groove bottom piece 10a and the second groove side piece 10c of the upper mating groove portion 10 on the upper frame material 5. Incidentally, in the upper frame member 5 of this embodiment, the leading edge portions of the front and rear second groove side pieces 10c are connected to each other via the connecting piece portion 5d.

[0012] By attaching the upper push edge 12 to the upper frame material 5, a first groove side piece 10b is arranged on the front-to-rear outer side of the upper fitting groove portion 10, and the upper push edge 12 has a main body portion 12a whose lower half is the first groove side piece 10b, and the upper half of the main body portion 12a is bent to form a locking piece portion 12b that engages with a locking receiving piece portion 5e that is bent and formed on the tip edge of the spanning piece portion 5a (groove bottom piece portion 10a), and a fixing piece portion 12c that is attached and fixed to the leg piece portion 3b of the upper rail material 3 together with the leg piece portion 5b of the upper frame material 5 via a screw 5c. When the upper pushing edge 12 is attached to the upper frame material 5, the tip 10bc of the first groove side piece portion 10b is set to be at the same height as the connecting piece portion 5d in the prospective direction.

[0013] On the other hand, the lower frame member 6 is U-shaped and has a spanning piece 6a and leg pieces 6b on both the front and rear sides, and the front and rear leg pieces 6b are fitted onto the leg pieces 4b of the lower rail member 4, thereby assembling the lower frame member 6 to the lower rail member 4. The upper halves 6ba of the front and rear leg pieces 6b form second groove side pieces 11c on the inside in the front-to-rear direction of the lower fitting groove portion 11, and the groove bottom pieces 11a of the lower fitting groove portion 11 are formed to protrude from the vertical middle portion that forms the lower end of the second groove side piece 11c toward the outside in the front-to-rear direction on the front and rear leg pieces 6b. In addition, the lower half 6bb of the lower frame member leg piece 6b is fixed to the leg piece 4b of the lower rail member 4 via a screw 6ca, thereby enabling the lower frame member 6 to be attached and fixed to the lower rail member 4.

[0014] The lower fitting groove portion 11, which is formed using the L-shaped groove bottom piece 11a and second groove side piece 11c of the lower frame material 6, further has a first groove side piece 11b formed on the lower pushing edge 13 that is attached to the lower frame material 6.The lower pushing edge 13 has the first groove side piece 11b formed on the upper half 13a, and upper and lower locking pieces 13c and 13d formed on the lower half 13b for attaching the lower pushing edge 13 to the lower frame material 6 by engaging with upper and lower locking receiving pieces 6c and 6d formed on the lower half 6bb of the lower frame material leg piece 6b.

[0015] In contrast, the vertical frame material 7 has left and right fitting groove portions 14 formed on both sides in the front-to-rear direction, which are open on the inside in the left-to-right direction and are composed of a groove bottom piece portion 14a, a first groove side piece portion 14b on the outside in the front-to-rear direction, and a second groove side piece portion 14c on the inside.The vertical frame material 7 also has fitting recess grooves 7a formed on the outside in the left-to-right direction so that it can be externally fitted onto a vertical rail material 15 provided on the wall surface W or an intermediate vertical support 16 provided between the ceiling surface H and the floor surface F. The vertical rail member 15 has a square shape that opens inward in the left-right direction, with the spanning piece 15a fixed to the wall W with screws 15c and both leg pieces 15b standing upright inward in the left-right direction from the wall W. The vertical frame member 7 is assembled in such a manner that the folded pieces 14e (described below) that constitute the front and rear leg pieces of the vertical frame member 7 are fitted onto the front and rear leg pieces 15b of the vertical rail member 15 configured in this way, and the vertical frame member 7 has a square shape that opens outward in the left-right direction by providing the groove bottom piece 7aa of the fitting groove 7a and the front and rear folded pieces 14e, and is configured so that its position can be adjusted in the left-right direction by adjusting the adjuster 15d provided between the spanning piece 15a of the vertical rail member 15. On the other hand, on the side of the intermediate vertical support 16, the groove bottom piece 7aa of the mating groove 7a is fixed to the intermediate vertical support 16 via a screw 7b, and the outer portion of the groove bottom piece 7aa in the front-to-rear direction forms the groove bottom piece 14a of the left and right mating groove portions 14, while the second groove side piece 14c of the left and right mating groove portions 14 extends inward in the left-to-right direction from the groove bottom piece 7aa, and further, a piece formed in a folded shape from both the front and rear end edges of the groove bottom piece 7aa facing outward in the left-to-right direction and outward in the front-to-rear direction forms the first groove side piece 14b. At this time, the tips 14bc, 14ca of the first and second groove side pieces 14b, 14c are set to have the same length of protrusion in the left-right direction (projection direction) from the groove bottom piece 14a. Furthermore, the left and right fitting groove portions 14 have groove bottom piece portions 14a that extend outward in the left-right direction beyond the second groove side piece portions 14c and the leg piece portions 15b of the vertical rail material 15, and a bent piece portion 14e is formed by bending outward in the left-right direction from the extended edge, and the left and right outer end edges of the bent piece portion 14e and the first groove side piece portion 14b are connected via the groove inner bottom piece portion 14f, positioned outward in the left-right direction and outward in the front-to-back direction than the groove bottom piece 14a.By configuring the left and right fitting groove portions 14 in this embodiment in this manner, a concave groove portion 14g that is narrower than the left and right fitting groove portions is formed at the inner left-right side of the left and right fitting groove portions 14.

[0016] In this way, the panel body 2 is assembled into the space formed by the upper and lower fitting grooves 10, 11 formed on both the front and rear sides of the upper and lower frame members 5, 6 and the left and right fitting grooves 14 formed in the vertical frame members 7 on both the left and right sides. In this case, the panel body 2 can be attached, for example, using the following procedure. The panel body 2 is placed on the groove bottom piece portion (setting block 17 described later) 11a of the lower fitting groove portion 11. The panel body 2 is moved to either the left or right side, and one side edge of the panel body 2 is fitted into the fitting groove portion 14. The panel body 2 is moved in opposite directions to the left and right, and both left and right edge portions are fitted into the fitting groove portions 14 in a substantially equal state. ·Attach the upper push edge 12 to the upper frame material 5. ·Attach the lower push edge 13 to the lower frame material 6. Incidentally, the installation work of the panel body 2 is not limited to the above-mentioned process, but can also be carried out from a state where the upper push edge 12 is installed but the lower push edge 13 is not installed, or from a state where both push edges 12, 13 are not installed, and can be carried out as appropriate at the work site. In the figure, 17 is a setting block provided on the groove bottom piece 11a of the lower mating groove portion 11, 18 is a pressing material provided in a forced fit manner between the first groove side piece portions 10b, 11b, 14b of each mating groove portion 10, 11, 14 and the panel body 2, and 19 is a bead material provided between the second groove side piece portions 10c, 11c, 14c of each mating groove portion 10, 11, 14 and the panel body 2.

[0017] In the partition 1 in which a pair of panel bodies 2 are fitted together at the front and rear in this manner, the space between the tip edges of the front and rear second groove side pieces 10c, 11c of the upper and lower fitting grooves 10, 11 is blocked by the connecting piece 5d and the spanning piece 6a, but the left and right fitting grooves 14 have nothing between the tip edges of the front and rear second groove side pieces 14c, and the middle part of the vertical frame material 7 in the front-to-back direction forms a concave middle groove 14d.Therefore, in this embodiment, in order to block this concave middle groove 14d, a U-shaped middle blocking material 20 is fitted in so that the leg piece 20b engages with the inner side surface of the second groove side piece 14c in the front-to-back direction, and the spanning piece 20a covers the space between the tip edges of the second groove side piece 14c.

[0018] The partition 1 shown in Figs. 2 to 6 is of a multi-layer design incorporating a pair of front and rear panel bodies 2, and has excellent sound insulation and heat insulation properties. On the other hand, the partition 1 of this embodiment can also be a single-layer specification in which one of the pair of panel bodies 2 is not attached, and in this case, it is necessary to block the fitting groove portions 10, 11, 14 on the top, bottom, left and right of the side on which the panel body 2 is not inserted and installed. Therefore, in this embodiment, an upper blocking material 21 is provided to block the upper mating groove portion 10, a lower blocking material 22 is provided to block the lower mating groove portion 11, and left and right blocking materials 23 are provided to block the left and right mating groove portions 14.

[0019] The upper sealing material 21 for sealing the upper mating groove portion 10 is an embodiment of the present invention, but it goes without saying that the upper sealing material 21 may also be used as the lower sealing material 22 and left and right sealing materials 23 for sealing the lower mating groove portion 11 and the left and right mating groove portions 14, if necessary.Next, we will explain the upper sealing material 21. Incidentally, the left and right blocking materials 23 in this embodiment have the same shape as the upper blocking material 21, but the mounting configuration of the left and right blocking materials 23 is approximately the same as that of the upper blocking material 21 in the second embodiment described later, so will be explained in the section on the second embodiment.

[0020] The upper blocking material 21 has a sword-like shape and includes a blocking piece 21a that blocks the opening edge of the upper mating groove 10, a first leg piece 21b that extends from the outer front-to-rear edge of the blocking piece 21a toward the groove bottom piece 10a in a state where it is closely opposed to the first groove side piece 10b and whose tip edge engages with the first groove side piece 10b, and a second leg piece 21c that extends from the middle front-to-rear of the blocking piece 21a toward the groove bottom piece 10a in a state where it is spaced apart from the second groove side piece 10c but is inclined (biased) toward the second groove side piece 10c.Furthermore, a third leg piece 21d that is shorter than the first and second leg pieces 21b, 21c is formed at the other front-to-rear edge of the blocking piece 21a and protrudes toward the groove bottom piece. The first leg portion 21b has a first locking portion 21ba formed at the tip end and a second locking portion 21bb formed at the base end. On the other hand, the second leg piece 21c has a bent piece 21e formed at the tip edge thereof, which is bent in an L-shape (or V-shape) toward the second groove side piece 10c.

[0021] In contrast, the second groove side piece 10c of the upper mating groove portion 10 has an inclined surface portion 10ca that bulges out in an inclined manner toward the first groove side piece 10b between the middle portion in the vertical direction and the portion just before the groove bottom piece 10a, and the second groove side piece 10c is further configured to reach the groove bottom piece 10a in a state where it is bent in a step-like manner from the inclined top portion 10cb of the inclined surface portion 10ca toward the inside in the front-to-rear direction, thereby forming a recessed groove portion 10cc. Furthermore, a protrusion 10cd is formed at the tip edge of the second groove side piece 10c, which protrudes as the connecting piece 5d extends, and this protrusion 10cd is configured to slightly narrow the opening width of the opening end of the mating groove portion 10.

[0022] The upper mating groove 10 can be blocked by fitting the upper mating material 21 into the upper mating groove 10 from below. In this case, the upper mating material 21 is fitted into a pre-fitting position before it is fitted into the upper mating groove 10 in an fitted position. The transformation operation of the upper mating material 21 from the pre-fitting position to the fitted position can be carried out as separate operations, namely, the process of putting the upper mating material 21 into the pre-fitting position and the process of putting the upper mating material into the fitted position, or it can be carried out as a single operation. This can be selected by the worker according to their needs. However, as a process, the pushing force that the upper mating material 21 receives during the fitting operation is weak in the pre-fitting process and strong in the subsequent fitting process, and is therefore distinguished by the different strengths.

[0023] First, in the process of fitting upper blocking material 21 to the pre-assembly position, bent piece 21e is fitted into upper fitting groove 10 in a state where it precedes first leg piece 21b. By fitting bent piece 21e in this manner, upper blocking material 21 is in an inclined state in which first leg piece 21b of blocking piece 21a is positioned downward, and first and second leg pieces 21b, 21c are fitted into upper fitting groove 10 (see FIG. 11(B)). Blocking material 21 is fitted until tip edge 21ea of ​​bent piece 21e reaches the lower end of inclined surface 10ca, and upper blocking material 21 reaches the pre-assembly position (see FIG. 11(C)). Incidentally, the blocking material 21 is in the inclined state before reaching this pre-assembly position, so the first leg piece 21b and the bent piece 21e are inserted without or only lightly contacting the first and second groove side pieces 10b and 10c, and the first and second leg pieces 21b and 21c are inserted and assembled without or only slightly elastically deforming, so the work (operation) to bring it into the pre-assembly position is a light pushing operation.

[0024] The upper blocking material 21, which has reached the pre-installation position in this manner, is forcibly pushed in to transform it into the installation position.When the outer edge portion (first leg portion side edge portion) 21ab of the blocking piece 21a, which is the lower end of the inclination, is forcibly pushed in with a stronger pushing force than when bringing it into the pre-installation position, the inner second leg portion 21c moves in a direction where the tip edge 21ea of ​​the bent piece 21e moves up the inclined surface portion 10ca (moves in an elastically deformed state where the distance between the first and second leg portions 21b, 21c narrows), and is subjected to resistance.In contrast, the outer first leg portion 21b moves in a plane and is therefore not subjected to such resistance.As a result, the movement of the first leg portion 21b becomes faster than the movement of the second leg portion 21c, and the inclination is corrected.This is how the correction means of the present invention is configured. As a result, the upper blocking material 21 is fitted into the upper mating groove portion 10 while rotating to correct the inclination around the tip edge portion 21ea of ​​the bent piece portion 21e which moves along the inclined surface portion 10ca while receiving resistance due to elastic deformation of the first and second leg pieces 21b and 21c (see Figures 11(D)(E)).

[0025] The tip edge 21ea of ​​the bent piece 21e then climbs over the inclined top 10cb of the inclined surface portion 10ca, transforming into an assembled position.When in this assembled position, the upper blocking material 21 has the blocking piece 21a flush with the connecting piece 5d, the first and second locking portions 21ba and 21bb formed on the first leg piece 21b lock with the first and second locking receiving portions 10ba and 10bb formed on the tip and base ends of the first groove side piece 10b, the tip edge 21ea of ​​the bent piece 21e becomes the third locking portion and locks with the recessed groove portion 10cc formed in the second groove side piece 10c as the third locking receiving portion, and the fourth locking portion 21db formed on the third leg piece 21d extends the connecting piece 5d and locks the protruding protrusion 10cd as the fourth engagement receiving portion.

[0026] By configuring the upper blocking material 21 in this manner, when it is transformed from the pre-installation position to the installation position, the inclined part is subjected to movement resistance, causing it to undergo a transformation movement that involves rotation, and it transforms into an assembled position with the inclination corrected.Therefore, in order for the upper blocking material 21, which is always subjected to a load in the downward direction, to come out of the upper mating groove portion 10, it must move against this resistance, thereby preventing it from coming out inadvertently.

[0027] Next, we will explain the lower blocking member 22. The lower blocking member 22 is a conventionally known member that is U-shaped and includes a blocking piece 22a that blocks the opening edge of the lower fitting groove 11, and a pair of first leg pieces 22b that extend from both front and rear edge sides of the blocking piece 22a and engage with first and second groove side pieces 11b, 11c of the lower fitting groove 11. The assembled position is achieved by fitting first locking portions 22ba that protrude from the pair of first leg pieces 22b into first and second locking receiving portions 11ba, 11ca that are cut out and formed in the first and second groove side pieces 11b, 11c, respectively. For reference, the process of fitting the lower blocking member 22 into the lower mating groove portion 11 is shown in Figure 16. Unlike the upper blocking member 21, which is fitted in an inclined state by being corrected by resistance, this member is fitted in a horizontal state from the beginning, so if this is used as an upper blocking member, there is a possibility that it may fall off accidentally.

[0028] In this way, the upper and lower mating grooves 10, 11 and the left and right mating grooves 14 on the side where the panel body 2 is not installed (the work chamber R side in this embodiment) are fitted with the corresponding upper and lower blocking materials 21, 22 and left and right blocking materials 23, and the intermediate groove 14d is fitted with the intermediate blocking material 20. In the assembled position in which each sealing material is fitted, on the upper fitting groove 10 side, the tip edge 10bc of the first groove side piece 10b, the sealing piece 21a of the upper sealing material 21, and the connecting piece 5d of the upper frame material 5 are flush with each other in the front-to-back direction (projection direction), while on the lower fitting groove 11 side, the tip edge 11bc of the first groove side piece 11b and the sealing piece 22a of the lower sealing material 22 are flush with each other in the front-to-back direction (projection direction). As a result, when the partition 1 is viewed from the front side (the side where the blocking materials 21, 22, 23 are fitted, which in this embodiment is the work chamber R side), the blocking materials (blocking piece portions 21a, 22a, 23a) do not protrude in the viewing direction from the tip edge portions 10bc, 11bc, 14bc of the first groove side piece portions, and the partition 1 can be made flat.

[0029] In the present embodiment configured as described above, when the partition 1 of the multi-layer specification in which the panel body 2 is fitted in the front and rear is used as a single-layer specification, the upper closing material 21 that closes the upper fitting groove 10 on the side where the panel body 2 is not fitted in is made up of a closing piece 21a that closes the opening edge of the upper fitting groove 10, a first leg piece 21b that extends from the outer edge of the closing piece 21a in the front-rear direction toward the groove bottom piece 10a while closely facing the first groove side piece 10b, and has first and second locking portions 21ba, 21bb formed at the tip and base ends that lock into the first and second locking receiving portions 10ba, 10bb formed on the first groove side piece 10b, and The upper blocking material 21 has a sword-like shape and is equipped with a second leg piece 21c extending from the front-to-rear middle of the piece 21a toward the groove bottom piece 10a with a gap (separated) from the second groove side piece 10c, and a bent piece 21e bent from the tip edge (lower edge) of the second leg piece 21c toward the opposing second groove side piece 10c, with the tip edge 21ea engaging with the fourth locking receiving portion (recessed groove portion described later) 10cc formed in the second groove bottom piece 10c.As a result, at the initial stage of inserting the upper blocking material 21 into the upper mating groove portion 10, the first and second leg pieces 21b, 21c are inserted in an inclined state with the bent piece 21e inserted first.

[0030] The upper blocking material 21 that has been fitted in an inclined manner can be fitted in an assembly position with the inclination corrected by further fitting and assembling it with a rotation to correct the inclination, which not only makes it easier to fit and assemble the upper blocking material 21, but also makes it possible to reliably prevent the fitted upper blocking material 21 from accidentally becoming loose or falling off. Moreover, in this case, the plugging material that is fitted in with inclination correction is the upper plugging material 21 that plugs the upper fitting groove portion 10, so that it is possible to prevent the upper plugging material 21 from being loosened and falling off inadvertently.

[0031] Furthermore, in this case, when fitting the upper blocking material 21 into the upper mating groove portion 10, the bent piece portion 21e is first fitted into the upper mating groove portion 10 in an inclined position, so that the upper blocking material 21 can be fitted into the pre-fitting position with a light pushing operation, and the edge portion on the first leg piece portion 21b side of the blocking piece portion 21a, which forms the apex of the inclination of the upper blocking material 21 in the pre-fitting position, can be fitted into the position in which the inclination is corrected by strongly forcibly pushing in, thereby improving workability. Furthermore, in the process of transforming this upper blocking material 21 from the pre-installation position to the installation position, an inclined surface portion 10ca is provided on the second groove side piece 10c so as to function as a correction means for correcting the inclination by providing resistance to the insertion movement of the bent piece portion 21e that was inserted earlier.As a result, when the upper blocking material 21, which is in an inclined pre-installation position, is forcibly pushed in to change to the installation position, the inclination can be easily corrected without any particular intention, and the transformation to the installation position is reliable.

[0032] The process for fitting the upper sealing member 21 into the upper fitting groove 10 is as follows: a step of fitting the first and second leg pieces 21b, 21c into the upper fitting groove 10 in a pre-assembly position in which the bent piece 21e is fitted first, so that the second groove piece 10c side of the upper closing piece 21 is inclined close to the opening edge of the upper fitting groove 10; a forcible pushing-in process of forcibly pushing in the blocking piece 21 a on the first leg piece 10 b side, which is the lower end of the inclined upper blocking piece 21, thereby correcting the inclined state of the upper blocking material 21; a step of fitting the upper closing member 21 into the assembly position in which the closing piece 21a closes the opening edge portion; By carrying out the above steps in order, the upper closing member 21 can be reliably fitted in and assembled without being accidentally pulled out.

[0033] Furthermore, in this assembly process, an inclined surface portion 10ca is provided on the second groove side piece portion 10c of the upper fitting groove portion 10 to form a correction means for correcting the inclination by applying resistance to correct the inclination of the upper blocking material 21, which is inclined in the pre-assembly position, and in the process of fitting the upper blocking material 21 into the pre-assembly position, the upper blocking material 21 is lightly pushed in before it interferes with the resistance-applying means, and the subsequent forced pushing process involves fitting in with rotation due to a corrective movement in which the upper blocking material 21 receives resistance from the resistance-applying means, and this is a strong pushing to transform the upper blocking material 21 into the normal assembly position, making the assembly work of the upper blocking material 21 easier.

[0034] <Second embodiment> The present invention is not limited to the first embodiment, but can also be implemented in the same manner as the second embodiment shown in FIG. 17 and subsequent figures. In this second embodiment, unlike the first embodiment, there is no vertical frame material (upright) 7 for connecting adjacent panel bodies 2, and the adjacent edge portions of the panel bodies 2 are connected by connecting means 2a such as adhesive or pressure-sensitive adhesive. Regarding the reference numerals used in this second embodiment, the same reference numerals are used for the same components as those in the first embodiment, and detailed explanations will be omitted unless particularly necessary.

[0035] In this second embodiment, the upper mating groove portions 10 formed at the front and rear of the upper frame material 5 are formed directly on the upper frame material 5 itself, and are not formed by attaching the upper push edge 12 to the upper frame material 5 as in the first embodiment. For this reason, the upper frame member 5 of this embodiment is formed with a groove bottom piece 10a and first and second groove side pieces 10b, 10c to form the front and rear upper fitting grooves 10. Then, by fitting a pair of front and rear panel bodies 2 into the upper frame member 10 thus formed, a multi-layer partition 1 is formed, but in a single-layer configuration in which one of the panel bodies 2 is not attached, in this embodiment, as in the first embodiment, a sword-shaped upper fitting groove 21 and a square-shaped lower fitting groove 22 are used for the upper and lower fitting grooves 10, 11 as fitting grooves 10, 11, and left and right fitting grooves 14 where the panel body 2 cannot be attached.

[0036] However, the specific mounting manner of the sword-shaped blocking materials 21, 23 is different from that of the first embodiment, and in this regard, the configuration for fitting and assembling the upper blocking material 21 into the upper mating groove portion 10 will be explained below. The upper blocking material 21 is then inserted into the upper mating groove portion 10 configured in this manner. In this case, the upper blocking material 21 is inserted into the upper mating groove portion 10 in an inclined position in which the folded piece portion 21e is inserted first (see Figure 25(B)). Then, as the upper blocking material 21 is inserted into the upper mating groove portion 10 while maintaining this inclined state, the tip edge portion 21da of the third leg piece portion 21d will come into contact with the connecting piece portion 5d which functions as the abutment receiving portion, and this state becomes the pre-assembly position of the upper blocking material 21 (see Figure 25 (D)), and up to this point the operation can be performed with a light push with almost no resistance.

[0037] In order to return the upper blocking material 21, which is in this pre-assembly position, to the assembly position, the outer edge portion 21ab in the front-to-back direction, which is the lower end of the inclined portion of the blocking piece 21a, is forcibly pushed in with great force.When this forcible pushing is performed, the tip edge portion 21da of the third leg piece 21d of the upper blocking material 21 moves (slides) the connecting piece portion 5d toward the outside in the front-to-back direction (see Figure 25(E)).As a result, the first leg piece 21b of the upper blocking material 21 moves faster than the second leg piece 21c, resulting in a movement accompanied by a rotation that corrects the inclination. The tip edge 21da of the third leg piece 21d passes over the protrusion 5da at the tip of the second groove side piece 10c and fits into the opening edge of the upper fitting groove 10, and the tip edge 21ea of ​​the folded piece 21e passes over the protrusion 10cd formed on the upper half of the second groove side piece 10c and engages with the upper edge of said protrusion 10cd, so that the upper sealing material 21 is transformed into an installation position in which it is fitted and installed into the upper fitting groove 10. By configuring in this manner, as with the first embodiment, there is no need to make the configuration of the upper frame material 5 and the upper blocking material 21 particularly complicated, and the posture of the upper blocking material 21 in an inclined state can be corrected with a simple configuration.

[0038] Furthermore, in this case, the abutment receiving portion is a connecting piece portion 5d which functions to reinforce the upper fitting groove portion 10 by connecting the front and rear second leg pieces 10c together, and as a result, the connecting piece portion 5d can also be used as the abutment receiving portion, which contributes to simplifying the structure. Incidentally, the left and right blocking members 23 provided to block the left and right fitting groove portions 14 are the same as the upper blocking piece 21, and are formed with a blocking piece 23a, first, second, and third leg pieces 23b, 23c, and 23d, and a bent piece 23e, just like the upper blocking piece 21. When the left and right blocking members 23 are in the pre-assembly position, the contact receiving portion with which the tip edge 23da of the third leg piece 23d abuts is formed by the spanning piece portion 20a of the intermediate blocking member 20 and the tip edge of the second groove side piece 14c that is adjacent to it, and the present invention can also be implemented in this manner.
