Summary of the Invention
Problems to be Solved by the Invention
[0004] In the column described in Patent Document 1, since the inside of the column is partitioned by a partition piece parallel to the partition panel, it is possible to prevent sound and light from leaking through the locking holes formed on both front and rear side surfaces. However, generally, since the column is made of a high-strength metal material, in order to form the column into a square tube shape, large and expensive machines such as extrusion and drawing processing machines must be used, increasing the manufacturing cost. Moreover, since it is necessary to fix both ends of the partition piece to the inner surface side of the column by welding or the like, the welding work is also troublesome. Further, simply partitioning the inside of the column into two front and rear spaces by the partition piece has limitations in significantly enhancing the sound insulation performance.
[0005] The present invention has been made paying attention to such problems, and an object thereof is to provide a column of a partition device that can be easily and inexpensively manufactured and has excellent sound insulation performance.
Means for Solving the Problems
[0006] In order to solve the above problems, the column of the partition device of the present invention is a column for supporting a partition panel, made of a pair of semi-finished products of columns having the same cross-sectional shape, and these pair of semi-finished products are fitted symmetrically in a plan view so that three partition spaces partitioned in the front-rear direction are formed inside, and are joined at a plurality of locations. According to this feature, by manufacturing two semi-finished products of columns having the same cross-sectional shape and fitting and joining them symmetrically in a plan view so that three partition spaces partitioned in the front-rear direction are formed inside, the column can be easily and inexpensively manufactured. Further, since three partition spaces partitioned in the front-rear direction are formed inside the column, it has excellent sound insulation performance and its strength is also increased.
[0007] The semi-finished product is characterized by having a base portion having a U-shaped cross-section in a plan view and an inward portion extending at a right angle from one free end of the base portion toward the other free end. According to this feature, by manufacturing two semi-finished products of columns having the same cross-sectional shape having a U-shaped cross-section base portion and an inward portion, and fitting and joining them symmetrically in a plan view so that three partition spaces partitioned in the front-rear direction are formed inside, the column can be easily and inexpensively manufactured. Further, the blocking property of each of the three partition spaces is enhanced.
[0008] At the other free end of the base portion having a U-shaped cross-section in a plan view, an outward portion extending at a right angle outward so as to face the same direction as the inward portion extending at a right angle from one free end of the base portion toward the other free end is continuously provided, and the outward portions respectively abutting on the left-right direction inner surfaces of the base portions in the pair of semi-finished products are continuously provided. According to this feature, since a part of the base portion in the left-right direction in the pair of semi-finished products has a double structure, the strength of the column is increased.
[0009] The outer portion is formed to have a length such that the tip thereof abuts against the inner surface of the base portion in the longitudinal direction. According to this feature, positioning becomes easy when fitting and joining a pair of semi-finished products.
[0010] The semi-finished product is formed of an iron-based material, and two locations on the left and right where the tip of the inner portion abuts against the base portion are joined by welding from the outside. According to this feature, since only two joining locations are required, not only the manufacturing cost of the column is reduced, but also the welding work becomes easy because welding is performed from the outside. In addition, an iron-based column having high strength and having three partition spaces inside can be provided.
[0011] A plurality of upper and lower locking holes for locking an optional member are formed on the outer side surface of the base portion in the left-right direction. According to this feature, an optional member can be easily locked to the column while maintaining sound insulation performance and light shielding performance.
[0012] An attachment portion to which a support member for supporting a side end portion of the partition panel can be attached is formed on the outer side surface of the base portion in the left-right direction. According to this feature, a support member can be attached to the attachment portion of a column having high strength with three partition spaces formed inside, and the partition panel can be supported safely and firmly.

Mode for Carrying Out the Invention
[0014] A mode for carrying out the support column of the partition device according to the present invention will be described below based on an example.
Example
[0015] The support column of the partition device according to the example will be described with reference to FIGS. 1 to 5. In the following, the outdoor side of the partition device is referred to as the front, the indoor side as the rear, and the connecting direction of the partition panels as the left - right direction (see FIGS. 4 and 5).
[0016] As shown in FIG. 1, the partition device 1 to which the present invention is applied includes a frame body 2 installed to stand on the floor surface. The frame body 2 includes six corner support columns 3 arranged at predetermined intervals in the front - rear - left - right directions with an up - down dimension lower than the ceiling surface, seven upper connecting rods 4 that connect the upper end portions of the respective corner support columns 3 at right angles so as to form a "day" shape in plan view, and seven lower connecting rods 5 that also connect the lower end portions of the respective corner support columns 3 at right angles so as to form a "day" shape in plan view.
[0017] A plurality of support columns 7 for panel support for supporting the side end portions of the partition panel 6 are attached between the upper connecting rod 4 and the lower connecting rod 5.
[0018] As shown in FIGS. 2 to 4, the column 7 is formed by fitting a pair of left and right semi-finished products (hereinafter abbreviated as semi-finished products) 71, 71 of the same cross-sectional shape made of an iron-based material, for example, steel. Each semi-finished product 71 includes a base portion 71a that is long in the vertical direction and has a U-shaped cross-section in plan view, an inward portion 71d that extends perpendicularly from one free end (tip) 71b of the base portion 71a toward the other free end 71c, and an outward portion 71e that extends perpendicularly outward in the same direction as the inward portion 71d from the other free end 71c of the base portion. The whole is integrally formed by bending a steel plate by pressing or the like. Note that the base portion 71a of the semi-finished product 71 is shorter by the plate thickness of the semi-finished product 71 than the leg having one free end 71b with respect to the leg having the other free end 71c. In other words, the outward portion 71e is located inward in the left and right directions of the semi-finished product 71 by the plate thickness of the semi-finished product 71 compared to the inward portion 71d.
[0019] At the center of the side surface portion in the front-rear direction (the side surface portion parallel to the partition panel) of the base portion 71a, a plurality of locking holes 8 in the vertical direction are provided for locking brackets or the like (all not shown in the figure) for supporting optional members such as a shelf board. Further, at both the upper and lower ends of the side surface portion in the front-rear direction, fixing pieces 71f, 71f fixed to the upper connecting rod 4 and the lower connecting rod 5 are integrally connected upward and downward, respectively. Furthermore, a plurality of female screw holes 10, which are attachment portions for attaching a support member 9 (see FIG. 5) for supporting the side end portion of the partition panel 6, are formed in the side surface portion in the left-right direction (the side surface portion perpendicular to the partition panel) of the base portion 71a.
[0020] To form the column 7, a pair of left and right semi-finished products 71, 71 are fitted symmetrically in plan view so that three partition spaces S1, S2, S3 partitioned in the front-rear direction are formed inside. The tips of the inward portions 71d, 71d are brought into contact with the outer surfaces in the front-rear direction of the base ends of the base portions 71a, 71a, respectively, and the outward portions 71e, 71e are brought into contact with the inner surfaces in the left-right direction of the base portions 71a, 71a, respectively. Note that, in order to facilitate positioning when fitting and joining the semi-finished products 71, 71, the extending dimensions of the outward portions 71e, 71e are formed to have a length such that their tips come into contact with the inner surfaces in the front-rear direction of the base portions 71a, 71a.
[0021] In this way, after fitting the semi-finished products 71, 71 so as to be symmetrical with respect to the plan view, the two positions before and after the tips of the inward portions 71d, 71d and the bases 71a, 17a come into contact are joined by welding 11, 11 from the outside, thereby forming the support column 7.
[0022] As shown in FIG. 5, on both the left and right sides of the support column 7 formed as described above, the side end portions of the two partition panels 6, 6 before and after are supported by the support members 9, 9. That is, by using the upper and lower female screw holes 10 formed on the left and right side surfaces in the lateral direction of the bases 71a, 71a, after fixing the plate-shaped support members 9, 9 having locking hooks 9a, 9a protruding in the front-rear direction at both the front and rear ends with screws 12, 12, a plurality of upper and lower locking holes (not shown) formed on the opposing surfaces of the side end portions of the two partition panels 6, 6 before and after are locked and supported by the locking hooks 9a, 9a at both ends of the support members 9, 9. At this time, the opposing surfaces of the left and right partition panels 6, 6 are separated and supported by the left and right dimensions of the locking holes 8 so that brackets or the like can be locked from the front-rear direction to the front and rear locking holes 8 formed in the base 71a.
[0023] As described above, in the support column 7 according to the embodiment, two semi-finished products 71, 71 of the support column having the same cross-sectional shape having a U-shaped cross-sectional base 71a, an inward portion 71d, and an outward portion 71e are manufactured, and these are simply fitted and joined symmetrically with respect to the plan view so that three partition spaces S1 to S3 partitioned in the front-rear direction are formed inside, whereby the support column 7 can be easily and inexpensively manufactured. Further, since three partition spaces S1 to S3 partitioned in the front-rear direction are formed inside the support column 7, the strength is also high. Furthermore, since the semi-finished products 71, 71 have the same structure, the number of parts is small and assembly errors are less likely to occur.
[0024] In addition, since three partition spaces S1 to S3 partitioned in the front-rear direction are formed inside the support column 7, even if the opposing surfaces of the left and right partition panels 6, 6 are separated and supported from the locking holes 8, sound and light do not leak to the outside from the locking holes 8, and it has excellent sound insulation performance and light shielding performance.
[0025] Furthermore, since the outward portion 71e abuts against the inner surface of the base portion 71a in the left - right direction, and a part of the base portion 71a in the left - right direction has a double - structure, the strength of the support column is further increased. Moreover, since the outward portion 71e is formed to have a length such that its tip abuts against the inner surface in the front - rear direction of the base portion, it becomes easy to position when fitting and joining the semi - products 71, 71 together.
[0026] Furthermore, since it is only necessary to join the two places on the left and right where the tip of the inward portion 71d abuts against the base portion 71a by welding 11, 11 from the outside, the manufacturing cost of the support column 7 is reduced and the welding work is also facilitated.
[0027] Furthermore, since female screw holes 10 to which a support member 9 for supporting the side end portion of the partition panel 6 can be attached are formed on the outer side surface portion of the base portion 71a in the left - right direction, the partition panel 6 can be safely and firmly supported via the support member 9 by the high - strength support column 7 in which three partition spaces S1 to S3 are formed inside.
[0028] As described above, the embodiments of the present invention have been described based on the drawings. However, the specific configuration is not limited to these embodiments, and even if there are additions or changes within the scope not departing from the gist of the present invention, they are included in the present invention.
[0029] For example, in the above - mentioned embodiment, the pair of semi - products 71 are assumed to have the outward portion 71e. However, as shown in FIG. 6, the outward portion 71e may be omitted, and only the other free end 71c of the base portion 71a may be brought into contact with the inner surface of the base portion 71a in the left - right direction. At this time, a plurality of upper and lower portions of the contact portion between the free end 71c and the base portion 71a may be spot - welded and joined.
[0030] Also, in the above - mentioned embodiment, the present invention is applied to the partition device 1 installed to stand on the floor surface. However, it goes without saying that the present invention can also be applied to a partition device installed between the ceiling and the floor surface.
