Description

Technical Field

[0001] The present invention relates to the technical field of vertical strut structures for partition panels provided to partition indoor spaces of buildings and the like.

Background Art

[0002] In general, partition panels are provided to partition indoor spaces of buildings and the like, and some of such partition panels are configured by assembling panel bodies between left and right vertical struts erected from the floor surface. The vertical struts employed in this case are of an integral type with a quadrangular shape, in which recessed grooves for fitting the panel bodies are formed on the peripheral surface portions facing left and right. Then, a vertical strut is erected at one end in the left-right direction of the site where the partition panel is to be installed, with the recessed groove on one end side arranged. After fitting one end of the panel body into the recessed groove on the other end side of the vertical strut, the next vertical strut is erected with the recessed groove on one end side fitted to the other end of the panel body, and then the operation of fitting one end of the next panel body into the recessed groove on the other end side of the vertical strut is repeated, so that the partition panel is formed by alternately assembling the vertical struts and the panel bodies. However, when the last vertical strut to be erected is near a wall, the groove side piece of the recessed groove portion of the last vertical strut will obstruct the operation, making it impossible to erect the strut. Therefore, in such a case, it has been attempted to use a split-type vertical strut that allows three panel bodies to be assembled in a T-shape and is split into two parts (for example, see Patent Document 1, Figure 13), and to employ this split-type vertical strut not only when assembling three panel bodies but also as the previous vertical strut. This split-type vertical strut is provided with three recessed grooves formed not only on both left and right sides but also on one side in the front-rear direction. It is divided into a strut main body portion in which the left and right recessed grooves are formed without the groove side piece on one side in the front-rear direction, and a strut split portion in which the recessed groove on one side in the front-rear direction is formed together with the groove side pieces on one side in the front-rear direction of the left and right recessed grooves, and is configured to be assembled by fastening the strut split portion to the strut main body portion via screws. In the final stage of assembling the partition panel, the last integrated vertical support column at the wall and the main support column section from which the previous support column division section has been removed are erected. After assembling the final panel, the support column division section is fastened to the main support column section with screws, thereby enabling the final panel to be assembled.

[0003] [Patent Document 1] Japanese Patent Publication No. 2018-71184 [Overview of the project] [Problems that the invention aims to solve]

[0004] While this configuration allows for efficient and smooth installation of partition panels against walls, the aforementioned segmented vertical support is fastened to the main support body via screws, which means that the segmented support may be misaligned laterally when fastened to the main support body. Furthermore, if the column division is fastened to the main column body in a position shifted to the right, for example as shown in Figure 9, the joint plate 5 attached to the groove on the left side will be attached in a loose and wobbly state. As a result, the joint plate 5 will vibrate unintentionally, producing an unpleasant rattling noise. Moreover, if the looseness becomes significant, it is predicted that the joint material may come off, among other problems. These are the issues that the present invention aims to solve. [Means for solving the problem]

[0005] The present invention was created in view of the above circumstances and with the aim of solving these problems, and the invention of claim 1 is a partition panel configured to divide the interior space front to back by fitting a panel into recessed grooves formed on the circumferential surfaces of adjacent rectangular vertical columns that are spaced apart in the left to right direction, and locking receiving parts are provided on both groove sides of the recessed grooves, and by locking a pair of locking parts provided on the joint material into the locking receiving parts, the joint material can be fitted into recessed grooves where there is no panel fitting, and the recessed grooves are sequentially located in the circumferential direction of the vertical columns, from first to fourth The vertical support structure for a partition panel is characterized in that the first to third recessed grooves are formed on at least the first to third recessed grooves of the circumferential surface, and the vertical support is divided into a main support portion having locking receiving portions on the fourth circumferential surface side of the first and third recessed grooves, and a divided support portion having both locking receiving portions of the second recessed groove and locking receiving portions on the second circumferential surface side of the first and third recessed grooves, and the vertical support is assembled by fastening the divided support portion to the main support portion, wherein the main support portion is provided with a second locking receiving portion that overlaps with the locking receiving portion on the second recessed groove side provided on the divided support portion, and the locking portion on that side of the joint board can be locked into it. The invention of claim 2 is a vertical support structure for a partition panel according to claim 1, characterized in that the pair of locking parts comprises a base end piece that extends from the back surface of the circumferential surface that forms the surface of the vertical support and is forcibly fitted between the locking receiving parts, an inclined piece that extends inclined from the tip edge of the base end piece so as to narrow the distance between them and the tip edge that is loosely fitted between the locking receiving parts, and a protruding part that protrudes from the outer edge of the inclined piece, and the second locking receiving part locks the protruding part that has been fitted beyond the second locking receiving part when the joint plate is installed. [Effects of the Invention]

[0006] By adopting the invention of claim 1, the vertical support column used to form the partition panel is of a split type, comprising a support column main body having locking receivers on the fourth circumferential surface side of the first and third recessed grooves, and a support column division section having locking receivers on both sides of the second recessed groove and locking receivers on the second circumferential surface side of the first and third recessed grooves, and assembled by fastening the support column division section to the support column main body, the support column main body is provided with a second locking receiver section that overlaps with the locking receiver section provided on the support column division section, allowing the locking receiver section on the joint board side to be locked. As a result, the joint board is locked not only on the support column division section side but also on the second locking receiver section on the support column main body side, ensuring a secure locking state is maintained even if the support column division section is installed in a misaligned position relative to the support column main body, thus preventing looseness. The invention of claim 2 is configured such that the pair of locking portions on the joint board side comprises a base end piece that extends from the circumferential surface that becomes the surface of the vertical support and is forcibly fitted between the locking receiving portions, an inclined piece that slopes from the tip edge of the base end piece so that the distance between opposing portions narrows and the tip edge is loosely fitted between the locking receiving portions, and a protruding portion that protrudes from the outer edge of the inclined piece, and the second locking receiving portion locks the protruding portion that has been fitted beyond the second locking receiving portion when the joint board is installed, and as a result the locking of the protruding portion to the second locking receiving portion occurs during the process of assembling the joint board into the groove, so that workability is not impaired.

[Modes for carrying out the invention]

[0008] Next, embodiments of the present invention will be described with reference to the drawings. In the drawings, 1 is a partition panel that divides an interior space front to back, and the partition panel 1 is composed of vertical support columns 2 and 3 erected with gaps on the left and right sides, and a panel body 4 incorporated between adjacent vertical support columns 2, 2 or between 2 and 3, but the space between the upper rail 6 provided on the upper edge of the panel body 4 and the ceiling rail 7 is configured as a transom section S without a transom board. In this case, the partition panel 1 is assembled from the leftmost wall W to the rightmost wall W in Figure 1, and the vertical support column 3 is erected just before the last vertical support column 2 which is erected in contact with the last rightmost wall W as the assembly of the partition panel 1 progresses from the left end, and the present invention is implemented in the vertical support column 3.

[0009] For convenience, the vertical supports 2 and 3 are defined as having a rectangular shape with first to fourth circumferential surfaces 2a to 2d and 3a to 3d formed sequentially from the left end in the circumferential direction. In this embodiment, they have a hollow rectangular tube shape, but they may also have a solid rectangular prism shape. One vertical support 2 is a single-piece type with first and second recessed grooves 2e formed in the first and third circumferential surfaces 2a and 2c facing each other on the left and right sides, for fitting and assembling the panel body 4. The other vertical support 3 has first to third recessed grooves 3e, 3f, and 3g formed in the first to third circumferential surfaces 3a, 3b, and 3c, and is a divided type divided into two sections as will be described later.

[0010] First, to specifically describe the integrated vertical support column 2, the vertical support column 2 has first and second recessed grooves 2e formed in the first and third circumferential surfaces 2a and 2c, which face each other on the left and right sides, for fitting and incorporating the panel body 4, while the second and fourth circumferential surfaces 2b and 2d, which face each other on the front and rear sides, do not have recessed grooves 2e and constitute the surface of the support column. The groove portion 2e is comprised of a groove bottom piece 2ea and a groove side piece 2eb that extends in an inclined manner (diagonally) from both the front and rear edges of the groove bottom piece 2ea, expanding in the front-rear direction, with its leading edge forming the corner portion 2ec of the vertical support 2. Furthermore, from the corner portion 2ec, a column surface piece 2ed is formed that extends inward in the front-rear direction and becomes the front and rear support surface of the first and third circumferential surface portions 2a and 2c. Between the opposing front and rear column surface pieces 2ed, a pair of left and right recessed groove portions 2e are formed by the groove bottom piece 2ea and the front and rear groove side pieces 2eb. The panel body 4 is fitted into the portion of the recessed groove portion 2e below the upper rail 6, and the joint material 5 is fitted into the upper portion. From the leading edge of the front and rear column surface pieces 2ed of the first and third circumferential surface portions 2a and 2c where the recessed groove portion 2e is formed, a first locking receiving portion (corresponding to the "locking receiving portion" of the present invention) 2ee is formed in a stepped, bent state, recessed into the column surface piece 2ed, for locking portions 5b formed at both end edges of the joint material 5 as described later.

[0011] On the other hand, in the joint material 5, a pair of locking portions 5b are formed to protrude in a leg piece shape at both edge portions on the back surface of the surface portion 5a. The pair of locking portions 5b are configured to include base end side piece portions 5ba protruding in parallel from the back surface of the surface portion 5a, inclined piece portions 5bb inclined from the distal end edges of the base end side piece portions 5ba toward the inner side in the width direction of the joint material 5, and protruding portions 5bc protruding from the outer side surface portions of the inclined piece portions 5bb. The outer dimension X between the base end side piece portions 5ba is set to be larger than the inner dimension T between the distal end edge portions of the opposed first locking receiving portions 2ee (T<X). When the joint material 5 is assembled into the recessed groove portion 2e, the base end side piece portions 5ba are forcibly fitted between the distal end edge portions of the opposed first locking receiving portions 2ee, so as to be mounted in a tightened state. The outer dimension Y between the distal end edges of the inclined piece portions 5bb is set to be smaller than the inner dimension T between the distal end edge portions of the first locking receiving portions 2ee (Y<T), thereby facilitating the fitting and assembly of the inclined piece portions 5bb between the distal end edge portions of the first locking receiving portions 2ee.

[0012] Further, the outer dimension Z between the distal end edge portions of the protruding portions 5bc is set to be greater than or equal to the outer dimension X between the base end side piece portions 5ba (Z≧X). In a state where the distal end edges of the inclined piece portions 5bb are fitted between the distal end edge portions of the first locking receiving portions 2ee, by forcibly pushing the joint material 5, the locking piece portions 5b are elastically deformed into a narrowed state, so that the distal end edge portions of the first locking receiving portions 2ee ride over the protruding portions 5bc to form a loose temporary holding state. By further forcibly pushing the joint material 5 from this temporary holding state, the joint material 5 is configured to be able to be fitted and mounted into the recessed groove portion 2e in a tightened state where the base end side piece portions 5ba are forcibly fitted to the distal end edge portions of the first locking receiving portions 2ee. Incidentally, the above dimensional relationship satisfies Y<T<X≦Z.

[0013] In contrast, the vertical support column 3 is sequentially provided with first to fourth peripheral surface portions 3a to 3d in the circumferential direction, of which the first, third, and second recessed groove portions 3e, 3g, and 3f are formed in the first, third, and second peripheral surface portions 3a, 3c, and 3b on the left, right, and one side in the front-rear direction, respectively, and the fourth peripheral surface portion 3d constitutes a column surface piece portion 3dd without a recessed groove portion being formed therein. Incidentally, the vertical support column 3 may, if necessary, have a fourth recessed groove portion formed in the fourth peripheral surface portion 3d, and in this case, the site where the fourth recessed groove portion is formed may be of a split type like the support column split portion 3Y of the present embodiment described later. The vertical support column 3 is provided with a support column main body portion 3X and a support column split portion 3Y, and is of a split type in which the support column split portion 3Y is fastened to the support column main body portion 3X via a screw 3h.

[0014] To be specific, the support column main body portion 3X has a square tubular shape, and among the first and third recessed groove portions 3e and 3g formed in the left and right first and third peripheral surface portions 3a and 3c, the groove bottom piece portions 3ea and 3ga, as well as the groove side piece portions 3eb and 3gb on the fourth peripheral surface portion 3d side, the corner portions 3ec and 3gc, the column surface piece portions 3ed and 3gd, and the first locking receiving portions 3ee and 3ge are all formed, and an auxiliary bottom surface portion 3i that connects the end edges of the two groove bottom piece portions 3ea and 3ga on the second peripheral surface portion 3b side to each other is also formed.

[0015] In contrast, the support column split portion 3Y is formed with a groove bottom piece portion 3fa of the second recessed groove portion 3f, groove side piece portions 3fb on both left and right sides, a corner portion 3fc serving as the tip of the groove side piece portion 3fb, a column surface piece portion 3fd extending from the corner portion 3fc, and a first locking receiving portion 3fe at the tip of the column surface piece portion 3fd. Of these, the groove side piece portion 3fb and the corner portion 3fc also serve as the groove side piece portions 3eb, 3gb and the corner portions 3ec, 3gc on the first and third recessed groove portions 3e, 3g side by attaching the support column split portion 3Y to the support column main body portion 3X. Furthermore, the corner portions 3ec and 3g of the two groove-side pieces 3fb, which serve as both the first and third groove portions 3e and 3g, are formed from the column surface pieces 3ed and 3gd on the second groove portion 3f side of the first and third groove portions 3e and 3g, and the first locking receiving portions 3ee and 3ge. The dimensional relationship between the first to third groove portions 3e and 3g when the vertical support column 3 is assembled is set to be the same as the dimensional relationship between the groove portion 2e of the vertical support column 2.

[0016] The vertical support column 3 is assembled by fastening the groove bottom piece 3fa formed in the support column division portion 3Y to the support column body portion 3X via screws 3h, with the groove bottom piece 3fa formed in the support column division portion 3Y in contact with the auxiliary bottom surface portion 3i. The support column body portion 3X is further formed with second locking receiving portions 3ej and 3gj. The second locking receiving portions 3ej and 3gj extend from the corner portions 3ef and 3gf between the groove bottom pieces 3ea and 3ga of the first and third recessed groove portions 3e and 3g and the auxiliary bottom surface portion 3i, and are provided in a state where they overlap (stack) with a gap in the left-right direction on the inner portion of the first locking receiving portions 3ee and 3ge on the second circumferential surface portion 3b side of the first and third recessed groove portions 3e and 3g. Furthermore, the tip portions of the second locking receiving portions 3ej and 3gj are set to protrude toward the fourth circumferential surface portion 3d side from the tip portions of the first locking receiving portions 3ee and 3ge, corresponding to the inclination of the inclined piece portion 5bb, and can be locked into the inward corner portion 5bd between the inclined piece portion 5bb and the protruding portion 5bc.

[0017] In the assembled vertical support 3, the lower part of the upper rail 6 is fitted with the panel body 4, so the joint material 5 is incorporated only into the second recessed groove 3f. However, as mentioned above, the transom section S is set up as an empty space without a transom board, so the joint board 5 is incorporated not only into the second recessed groove 3f provided in the support division section 3Y, but also into the first and third recessed grooves 3e and 3g.

[0018] When the jointing material 5 is incorporated into the first and third grooves 3e and 3g in this manner, the locking portion 5b of the jointing material 5 is installed in a non-loosening state by forcibly fitting (press-fitting) the base end portion 5ba between the first locking receiving portions 3ee and 3ge of the first and third grooves 3e and 3g, similar to when the jointing material 5 is incorporated into the groove 2e of the vertical support 2. Furthermore, the protruding portion 5bc provided on the locking portion 5b will be fitted beyond the second locking receiving portion 3ej. With this configuration, in the transom section S, as shown in Figure 7, which is an enlarged view of the right side of the column division section 3Y in Figure 5(B), the second locking receiver 3gj is attached in a state of being secured by locking it into the inward-cornered portion 5bd on the base end side (surface side 5a) of the protruding portion 5bc. The joint plate 5 is then attached in a double state of being secured by the forced fit of the first locking receiver 3ge into the base end side piece 5ba and by the locking of the second locking receiver 3gj into the inward-cornered portion 5bd. This attachment configuration is the same not only for the right-side recessed groove section 3g of the column division section 3Y but also for the left-side recessed groove section 3e.

[0019] In other words, the joint plate 5 is installed in a double-locking state, with the main support portion 3X side and the split support portion 3Y side preventing it from coming loose. As a result, if the split support portion 3Y is installed misaligned in the left-right direction relative to the main support portion 3X, as shown in Figure 8, the press-fitting of the base end piece 5ba by the first locking receiver 3ee is eliminated, and the locking function of the first locking receiver 3ee becomes loose (or disappears). However, the corner-shaped part 5bd of the protruding portion 5bc is locked into the second locking receivers 3ej and 3gj provided on the main support portion 3X side, resulting in a firm locking mechanism. This prevents the joint material 5 from becoming loosely fitted, rattling, or coming loose, as is the case with conventional joints that do not have the second locking receivers 3ej and 3gj (see Figure 9).

[0020] In this embodiment, configured as described above, the second-to-last vertical support column 3 erected when the partition panel 1 is set up against the wall W is a split type, consisting of a support column body 3X with first locking receiving parts 3ee and 3ge formed on the fourth circumferential surface 3d side of the first and third recessed grooves 3e and 3g, and a support column split section 3Y with both locking receiving parts 3fe of the second recessed groove 3f and first locking receiving parts 3ee and 3ge formed on the second circumferential surface 3b side of the first and third recessed grooves 3e and 3g. The split section 3Y is assembled by fastening the support column split section 3Y to the support column body 3X via screws 3h, and is also used as a vertical support column 3 for attaching the panel body 4 on three sides.

[0021] Then, in the main body portion 3X of the vertical support column 3 configured in this way, second locking receiving portions 3ej and 3gj are formed that overlap with the first locking receiving portions 3ee and 3ge on the second groove portion 3f side of the first and third groove portions 3e and 3g provided in the support column division portion 3Y. The protruding portions 5bc of the locking portion 5b formed in the joint material 5 incorporated into the first and third groove portions 3e and 3g are locked to the second locking receiving portions 3ej and 3gj. As a result, the joint plate 5 has a double locking structure that prevents it from coming loose, being locked not only by the first locking receiving portions 3ee and 3ge on the support column division portion 3Y side, but also by the second locking receiving portions 3ej and 3gj on the support column main body portion 3X side.

[0022] Therefore, even if the first locking receivers 3ee and 3ge loosen the locking mechanism on the column division 3Y side due to the column division 3Y being mounted with a lateral displacement on the column body 3X side, the joint plate 5 will remain securely attached on the column body 3X side, where the inward-angled corner portion 5bd of the protruding portion 5bc is locked to the second locking receiver 3ej. As a result, the joint plate 5 will be firmly attached to the column body 3X side, preventing it from rattling or coming loose.

[0023] Moreover, in this case, the pair of locking portions 5b on the joint board 5 side are configured to include a base end piece 5ba that is forcibly fitted between the first locking receiving portions 3ee, 3ee or 3ge, 3ge which are formed extending from the circumferential surface portion that becomes the surface of the vertical support column 3, an inclined piece 5bb that is inclined from the tip edge of the base end piece 5ba so that the distance between them narrows, and whose tip edge is loosely fitted between the first locking receiving portions 3ee, 3ee or 3ge, 3ge, and a protruding portion 5bc that protrudes from the outer edge of the inclined piece 5bb, and the second locking receiving portions 3ej, 3gj formed on the main support column portion 3X will lock into the inward corner portion 5bd of the protruding portion 5bc that has been fitted beyond the second locking receiving portions 3ej, 3gj when the joint board 5 is installed, with respect to the inclined piece 5bb. As a result, the locking of the protruding portion 5bc to the second locking receiving portion 3ej, 3gj, which is a side member of the main support column portion 3X, occurs during the process of assembling the joint plate 5 into the first and third recessed groove portions 3e, 3g, without impairing work efficiency.
