JP-A-11-290140

  In the conventional rack shelf frame as shown in Patent Document 1, no matter how many sub-beam members are installed between a pair of front and rear beam members, both ends of each sub-beam member are simply hooked on the beam members. Therefore, the shelf frame itself assembled with the beam material and the sub-beam material cannot be expected to have such a strength that the whole rectangular planar shape can be maintained. Therefore, depending on the strength and installation strength of the pair of left and right side frame structures themselves that support both ends of the pair of front and rear beam members, or the coupling structure between the side frame structures and each beam member, There is a risk that a twisting phenomenon in which the pair of beam members move relative to each other in the opposite direction may occur, which is problematic in terms of safety and stability.

The present invention proposes a rack capable of solving the conventional problems as described above, and the rack according to the present invention as claimed in claim 1 understands the relationship with the embodiments described later. For the sake of simplicity, when the reference numerals used in the description of the embodiment are shown in parentheses, the length direction of the beam material (2a, 2b) is between the pair of front and rear beam materials (2a, 2b). The sub-beam material (3a, 3b) is placed at appropriate intervals between the notches (15a, 15b) on the beam material (2a, 2b) side and the protrusions (12a, 12b) on both ends of the sub-beam material (3a, 3b). a rack having a rack frame comprising bridged by fitting direction, said pair of front and rear beam members (2a, 2b) between the sub-beam member (3a, 3b) Alternatively, both ends wherein In the rack in which the reinforcing connecting member (7) screwed to the beam material (2a, 2b) is installed ,
The reinforcing connecting member (7) is made of a pipe material, and at both ends of the reinforcing connecting member (7), a vertical flat thick plate portion (18a, 18b) formed by crushing both end portions of the pipe material. ) Are bent at right angles to the sides, and mounting plate portions (19a, 19b) are provided.The mounting holes (20) provided in the mounting plate portions (19a, 19b) and the beam members (2a, 2b) Both ends of the reinforcing connecting member (7) are attached to the beam material (2a, 2b) by bolts (22) and nuts (23) penetrating through attachment holes (21) provided in the vertical plate portion . It is configured.

Although the mounting plate portions (19a, 19b) at both ends of the reinforcing connecting member (7) can be bent in the same direction, the mounting plate portions (19a, 19b) at both ends as described in claim 2. It is desirable to bend them in opposite directions. Furthermore, as described in claim 3 , the flat thick plate portions (18a, 18b) constituting the mounting plate portions (19a, 19b) at both ends of the reinforcing connecting member (7) are made of the pipe material. The pipe plate material is formed eccentrically on both sides in the diametrical direction so as to be flush with both sides in the diametrical direction, and the mounting plate portions (19a, 19b) are provided with the respective flat thick plate portions (18a, 18b). It can be configured to be bent at a right angle in a direction away from the center line of the pipe material.

As a general rack, the shelf frame (1) is provided with at least two loading areas (1A, 1B) in the length direction of the beam members (2a, 2b). The area (1A, 1B) is composed of at least two sub-beam materials (3a, 3b). In this case, as described in claim 4 , the reinforcing connecting member (7) At least one can be arranged between two adjacent loading areas (1A, 1B).

Further, as described in claim 5 , a horizontal brace material (24a, 24b) can be installed on the shelf frame (1) obliquely below the sub-beam material (3a, 3b). In this case, as described in claim 6, wherein the horizontal brace (24a, 24b), a pair of beam members that both front and rear ends (2a, 2b) may be screwed into, according to claim 7 As described above, at least one end of the horizontal brace material (24a, 24b) can be screwed to the reinforcing connecting member (7).

  According to the configuration of the present invention as set forth in claim 1, the sub beam material that needs to be incorporated into a single shelf frame is simply a beam material without being screwed to a pair of front and rear beam materials. The shelf frame can be constructed by laying between a pair of front and rear beam members with only a very simple operation of fitting the notch on the side and the protrusions on both ends of the sub beam material in the vertical direction. However, when there is no reinforcing connecting member between the pair of front and rear beam members, and there is a reinforcing connecting member that is installed with both ends screwed to the beam member. The strength of the entire shelf frame is increased compared to the conventional case, which eliminates the risk of the twisting phenomenon that the pair of front and rear beam members move relative to each other when external force is applied, as in the past. And Qualitative is improved.

The reinforcing connecting member may have any structure using a rod-like body or a plate-like body, but according to the configuration of the present invention , the reinforcing connecting member provided with a right-angled lateral mounting plate at both ends, Since it can be configured easily and inexpensively with only pipe material without combining different members, it is lightweight and has sufficient bending strength and can be easily attached to the vertical plate of the beam material with bolts and nuts. A connecting member can be obtained. Further , according to the configuration of the second aspect , compared to the case where the mounting plate portions at both ends are bent in the same direction, the screwing positions by the bolts and nuts with respect to the pair of front and rear beam members are the same. The desired twisting prevention effect can be enhanced by separating them in the length direction of the bolt. Further, according to the configuration of claim 3 , the bolts for the pair of front and rear beam members at both ends of the reinforcing connecting member Not only can the screwing position with the nut be further separated in the length direction of the beam material to further enhance the expected twisting prevention effect, but also the length of the mounting plate can be kept to a minimum while compensating. The position of the mounting hole of each mounting plate portion can be sufficiently separated laterally with respect to the reinforcing connecting member, and the screwing operation with the bolt and nut can be easily performed.

Further, as compared with the case where the reinforcing connecting member is directly below the load mounting area on the shelf frame, according to the configuration of claim 4 , the entire load mounting is performed for maintenance management of the reinforcing connecting member. It is not necessary to remove the load on the area, and maintenance of the reinforcing connecting member can be easily performed. In such a configuration, the number of reinforcing connecting members used is naturally reduced, and the expected effect of preventing twisting may not be sufficiently obtained. When the twisting phenomenon described above is likely to occur, the structure described in claim 5 or 6 can be employed to supplement the effect of preventing twisting on the shelf frame. Furthermore, according to the structure of Claim 7 , the end part of the horizontal brace material arrange | positioned under the load mounting area, ie, the edge part near the connection member for reinforcement between load mounting areas, is concerned. Regardless of the presence of the sub-beam material arranged adjacent to the reinforcing connecting member, it can be easily attached, and at the same time, the reinforcing connecting member itself can be reinforced by connecting the horizontal brace material. The strength of the entire frame can be further increased.

  In FIG. 1, 1 is a shelf frame provided with two loading areas 1A and 1B along the frontage direction, and a pair of front and rear beam members 2a and 2b parallel to the frontage direction, Two sub-beam members 3a and 3b are installed in parallel with the depth direction, two for each loading area 1A and 1B between 2b. The shelf frame 1 includes a pair of left and right lattice support shelves 6a and 6b configured by a connecting member 5 disposed between a pair of front and rear support members 4a and 4b and both support members 4a and 4b. Both ends of the pair of front and rear beam members 2a and 2b are horizontally supported in a state of being locked to the support members 4a and 4b. Reference numeral 7 denotes a reinforcing connecting member, which is installed between the pair of front and rear beam members 2a and 2b in a direction perpendicular to the respective beam members 2a and 2b at the central position between the two loading areas 1A and 1B. Yes. In addition, in the figure, one of the shelf frames 1 that is installed in a plurality of upper and lower stages between the pair of left and right shelf support frames 6a and 6b is illustrated.

  Hereinafter, as will be described in detail, as shown in FIGS. 2 to 4, the beam members 2 a and 2 b have longitudinally symmetric longitudinal sections, and a pair of upper and lower outer horizontal plate portions 8 a and 8 b, A groove-shaped plate portion 9 disposed between a pair of upper and lower outer horizontal plate portions 8a and 8b and having a recessed groove portion opened outward, an outer side of the pair of upper and lower outer horizontal plate portions 8a and 8b, and the groove-shaped plate The upper and lower horizontal plate portions of the portion 9 are made of a vertically symmetrical mold material composed of a pair of upper and lower inclined plate portions 10a and 10b that connect the outer sides of the horizontal plate portions. In addition, the vertical overhang | projection board part is bent and provided in the inner side of a pair of upper and lower outer horizontal board parts 8a and 8b at a right angle inward.

  The sub-beam members 3a and 3b are made of a mold material having a lip-shaped cross-sectional shape in which a horizontal projecting plate portion is connected in a right-angle inward direction from the lower side of both the left and right vertical plate portions 11a and 11b. At both ends in the direction, a pair of left and right protrusions formed by extending the lower half of the left and right vertical plate portions 11a and 11b and a horizontal projecting plate portion from the lower side thereof in the length direction of the sub-beam material 3. The parts 12a and 12b are provided. The pair of left and right projections 12a and 12b are formed with rectangular recesses 13a and 13b on the inner side of the horizontal projecting plate at a position near the tip.

  On the other hand, the beam materials 2a and 2b are provided with sub beam material support portions 14 at equal intervals in the beam material length direction. The sub-beam material support portion 14 is constituted by a pair of left and right cutout portions 15 a and 15 b formed at the upper protruding corner portion of the groove-shaped plate portion 9. A protruding plate portion 16 that protrudes inward from the adjacent inner sides of the vertical hole portions of the notches 15a and 15b is formed.

  The sub beam members 3a and 3b have a total length such that the pair of left and right protrusions 12a and 12b at both ends thereof can be placed on the pair of front and rear beam members 2a and 2b. Accordingly, when the sub beam members 3a and 3b are installed between the pair of front and rear beam members 2a and 2b, the sub beam members 3a and 3b are lowered between the beam members 2a and 2b in an oblique posture with respect to the beam members 2a and 2b. The sub-beam members 3a and 3b are horizontally rotated to a posture perpendicular to the beam members 2a and 2b, and the projecting portions 12a and 12b at both ends thereof are positioned above the channel plate 9 in the beam members 2a and 2b. Insert it. Thereafter, the sub-beam members 3a and 3b are lowered, and the tip portions of the protruding portions 12a and 12b at both ends of the sub-beam members 3a and 3b are left and right in the selected one sub-beam member support 14 on the beam members 2a and 2b side. The pair of notches 15a and 15b are fitted. At this time, the protruding plate portion 16 provided in the notches 15a and 15b is fitted into the recessed portions 13a and 13b of the protruding portions 12a and 12b to limit the play allowance in the length direction of the sub-beam members 3a and 3b. It will be.

  As described above, each of the loading areas 1A and 1B on the shelf frame 1 is formed by the pair of left and right sub beam members 3a and 3b installed horizontally between the pair of front and rear beam members 2a and 2b. The sub-beam members 3a and 3b have protrusions 12a and 12b on the side of the sub-beam members 3a and 3b at the notches 15a and 15b of the sub-beam member support 14 provided on the pair of front and rear beam members 2a and 2b. The pair of beam members 2a and 2b are not rigidly coupled so as to prevent relative movement in the length direction. Therefore, when an external force is applied to move the pair of front and rear beam members 2a and 2b in the length direction, the shelf frame 1 may be twisted. In order to solve this problem, the reinforcing connecting member 7 is incorporated.

  As shown in FIGS. 2 to 5, the reinforcing connecting member 7 includes vertical flat thick plate portions 18 a and 18 b formed by crushing regions of a predetermined length at both ends of a main body 17 made of a round pipe material. Are formed on the mounting plate portions 19a and 19b. The mounting plate portions 19a and 19b at both ends are configured such that the distance between the outer surfaces is substantially equal to the interval between the vertical plate portions of the channel plate 9 of the pair of front and rear beam members 2a and 2b. In this embodiment, the flat thick plate portions 18a, 18b at both ends are formed eccentrically on both diametrical sides of the main body 17 so as to be flush with the diametrical both side surfaces of the main body 17, respectively. 19a and 19b are bent at right angles to the flat plate portions 18a and 18b in directions opposite to each other in a direction away from the center line of the main body 17, and mounting holes 20 are formed in the mounting plate portions 19a and 19b. Has been. On the other hand, the vertical plate portion of the grooved plate portion 9 of the beam members 2a and 2b has a center position between a pair of left and right cutout portions 15a and 15b and a cutout portion 15a and 15b for each sub-beam material support portion 14. A mounting hole 21 is provided at a lower position. And the horizontal distance (horizontal distance L shown in FIG. 5B) in the direction perpendicular to the main body 17 between the two mounting holes 20 on both ends of the reinforcing connecting member 7 and the mounting holes 21 on the beam members 2a and 2b side. The distance (the distance D shown in FIG. 4 = the distance between the sub-beam material support portions 14) is configured to be equal.

  Therefore, between the two load placement areas 1A and 1B on the shelf frame 7, the reinforcing connecting member 7 is disposed in the horizontal direction between the pair of front and rear beam members 2a and 2b, and both ends of the reinforcing connecting member 7 are arranged. The mounting plate portions 19a and 19b are adjacent to the vertical plate portion of the groove-shaped plate portion 9 in each of the beam members 2a and 2b, and the mounting holes 20 of the mounting plate portions 19a and 19b are attached to the beam members 2a and 2b side. The bolts 22 and the nuts 23 inserted inward from the outside of the beam members 2a and 2b across the two mounting holes 20 and 21 in a state where the holes 21 are matched with each other, the mounting plate portions 19a and 19b and the beam member. The vertical plate portion of the channel plate portion 9 in 2a and 2b can be fastened and integrated with each other.

  As shown in FIG. 5C, the flat thick plate portions 18a and 18b formed by crushing the fixed regions at both ends of the main body 17 of the reinforcing connecting member 7 are formed at the axial center positions of the main body 17, and are connected to each other. The mounting plate portions 19a and 19b may be formed by bending in a reverse direction at a right angle. In this case, if the distance from the free ends of the mounting plate portions 19a and 19b to the mounting hole 20 is constant, the horizontal distance perpendicular to the main body 17 between the mounting holes 20 (horizontal distance L shown in FIG. 5B). In order to ensure this, the length of the mounting plate portions 19a and 19b must be increased.

  In the case where the number of load placement areas formed on the shelf frame 1 is increased, or in the case of a shelf frame on which heavy objects are placed, one reinforcing connecting member 7 is installed between the beam members 2a and 2b. If a sufficient reinforcing effect cannot be obtained simply by doing, the number of reinforcing connecting members 7 can be increased. Also, without increasing the number of reinforcing connecting members 7, or at the same time as increasing the number of reinforcing connecting members 7, as shown in FIG. 6, the sub beam members 3a and 3b are placed between the pair of front and rear beam members 2a and 2b. Two horizontal brace members 24a and 24b intersecting each other can be arranged on the lower side, and both ends of each horizontal brace member 24a and 24b can be screwed to the pair of front and rear beam members 2a and 2b.

The mounting plate portions 26a and 26b are formed by vertically bending along a fold line parallel to the length direction of both beam members 2a and 2b, and both mounting plate portions 26a and 26b have mounting holes. 27 is drilled. The distance between the mounting plates 26a and 26b in the direction parallel to the length direction of the beam members 2a and 2b between the mounting holes 27 is the distance between the mounting holes 21 on the beam materials 2a and 2b side (between the sub beam material support portions 14). It is configured to be an integral multiple of the interval.

  The two horizontal brace members 24a and 24b having the above-described configuration are formed by connecting the mounting plate portions 26a and 26b at both ends to the beam material in a state where the center portions in the length direction of the main bodies 25 are vertically crossed. 2a and 2b are adjacent to the vertical plate portion of the groove-shaped plate portion 9, and the attachment holes 27 of the attachment plate portions 26a and 26b are matched with the attachment holes 21 on the beam members 2a and 2b side. 27, bolts 28 and nuts 29 inserted inward from the outside of the beam members 2a and 2b between the attachment members 26a and 26b and the vertical plate portion of the groove plate 9 in the beam members 2a and 2b. By being fastened and integrated with each other, it is installed between the pair of front and rear beam members 2a and 2b.

  As shown in FIG. 9, of the ends of the two intersecting horizontal braces 24a and 24b, the end on the side where the reinforcing connecting member 7 is provided is not a beam member 2a or 2b but a reinforcing member. It is also possible to screw on the connecting member 7. In this case, the mounting plate portion 26a which is continuously bent upward is formed on both sides of the main body 25 constituting the horizontal brace members 24a and 24b, on the side screwed to the beam members 2a and 2b. As shown in FIGS. 10 and 11, a horizontal mounting plate portion 30 that enters the lower side of the reinforcing connecting member 7 is formed at the end of the side by extending the main body 25. Directional mounting holes 31 are provided. In use, the ends opposite to the reinforcing connecting members 7 of the two ends of each of the two intersecting horizontal braces 24a and 24b arranged in the both loading areas 1A and 1B are mounted upward. As described above, the plate member 26a is used to fasten the vertical plate portion of the channel plate portion 9 in the beam members 2a and 2b with bolts 22 and nuts 23, and the end portion on the reinforcing connecting member 7 side is used for the reinforcement. What is necessary is just to fasten to the lower side of the connection member 7 for reinforcement with the volt | bolt 32 and the nut 33 which penetrate the attachment hole 31 of the horizontal attachment board part 30 contacted with the connection member 7 and this lower side perpendicularly | vertically.

  When one reinforcing connecting member 7 is installed between the loading areas 1A and 1B, the horizontal mounting plate portions 30 of the horizontal brace members 24a and 24b installed on both sides of the reinforcing connecting member 7 are reinforced. It is possible to shift the position of the connecting member 7 in the length direction and attach the bolts 32 and nuts 33 separately, but two horizontal mounting plate portions 30 located on the same side as shown in FIG. In this state, it is desirable to attach to one place of the reinforcing connecting member 7 with one bolt 32 and nut 33.

  In the above-described embodiment, two horizontal brace members 24a and 24b that cross each other are installed in each loading area 1A and 1B, but one horizontal brace material 24a or 24b is installed in each loading area 1A and 1B. You may do it. In this case, it is preferable to arrange the horizontal brace members of the adjacent loading areas 1A and 1B so that the inclination directions thereof are alternately different. Also, the ends of the horizontal brace members 24a and 24b may be screwed to the beam members 2a and 2b at both ends, or the reinforcing connecting member 7 is installed adjacent to both ends or one end of the horizontal brace members 24a and 24b. When it is done, both ends or one end of the horizontal brace members 24 a and 24 b adjacent to the reinforcing connecting member 7 may be screwed to the reinforcing connecting member 7.
