DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a spacer for a connecting member to a column, and more particularly, to a fastener for penetrating a connecting hole with an end inserted into the opening side of a main body of a rack column. The present invention relates to a spacer which is connected to a support via a tool and is attached to an end of a connecting member having an opening extending in a longitudinal direction.

[0002]

2. Description of the Related Art Conventionally, an assembling rack is provided with a total of four struts, at least two struts in front and back, and a brace (lattice) and a horizontal member for connecting struts arranged in a row direction (front and rear). It is assembled by attaching a shelf material to an attachment portion provided on each support. Then, by placing a load on the shelf material, the load is stored in the shelf.

[0003] As a structure for connecting a rack support to a strut or a horizontal member, there is a conventional structure using a support having an opening extending along the longitudinal direction of the support. For example, JP-A-5-116718 discloses a support 31 having a pair of connecting plate portions 31b extending parallel to each other at a predetermined interval smaller than the width of the main body 31a on the opening side of the main body 31a, as shown in FIG. A structure in which a braid (lattice) 32 having a U-shaped cross section and a horizontal member 33 are assembled is disclosed.

[0004] In this structure, a column 31 erected up and down is used.
Are arranged such that the connecting plate portions 31b face each other. At the ends of the bracing 32 and the horizontal member 33, connection holes 32a and 33a are formed, and the ends thereof are connected to the connection plate portion 31.
Each is inserted into a predetermined position between b. A connection hole 31c formed in the connection plate portion 31b and a bracing 32
The bracing 32 and the horizontal member 33 are fixed to the columns 31 by rivets 34 penetrating through the holes 32a and 33a of the horizontal member 33. Bends 32c, 33c serving as spacers are integrally formed between the side walls 32b, 33b at the ends of the bracing 32 and the horizontal member 33.

[0005] As shown in FIG. 7, the connecting plate portion 31 b of the column 31 and, for example, a brace 32 are bolted together with a cylindrical spacer 35 interposed between the inner surfaces of both side walls 32 b of the brace 32. A connection method of tightening and fixing with a nut 36 and a nut 37 is also implemented. Spacer 35 is connected plate portion 31
When b and the connecting member such as the brace 32 are firmly tightened with the bolt 36 and the nut 37, the connecting plate portion 31b and the connecting member play a role of preventing plastic deformation of the connecting member.

In the case where the rack is a pallet rack used for storing loads loaded on a pallet, FIG.
As shown in FIG. 3, a support column 3 in which mounting holes 38 are formed at a predetermined pitch in a wall 31d facing a connecting plate portion 31b of a main body 31a.
1 is used. Then, the connecting direction of the rack (FIG. 8A)
A beam 40 (only one end is shown) is provided between two adjacent columns 31 arranged side by side in the horizontal direction of FIG. A locking claw 39a is formed on the mounting piece 39 at the same pitch as the mounting hole 38, and the locking claw 39a is locked in the mounting hole 38 so that the beam 4
0 is attached to the column 31. Further, in the case of the columns 31 constituting the rack of the automatic warehouse, as shown in FIG. 8B, engagement holes 41 are formed on both side walls of the main body 31a at a predetermined pitch. A load receiving shelf 42 provided with a locking claw 42a lockable to the engaging hole 41 is disposed between the pair of front and rear columns 31 constituting the rack so as to extend in the front-rear direction. Then, the load is supported by the load receiving shelves 42 which are arranged to face each other.

[0007]

In order to prevent the rack from being damaged by the shaking of the rack during an earthquake, it is necessary to firmly fix the connecting plate 31b and the connecting member such as the bracing 32. . In order to prevent the side wall of the connecting member and the connecting plate portion 31b from being plastically deformed by a strong fastening force of the fastener, it is necessary to arrange the spacer 35 on the inner surface of the side wall of the connecting member. However, when the spacer 35 independent of the connecting member is used as in the connecting structure shown in FIG. 7, when connecting the connecting member such as the brace 32 to the column 31, the end of the connecting member is connected to the connecting plate portion. It is necessary to dispose the bolt 36 in the hole 31c of the connecting plate portion 31b or the like while arranging it at a predetermined position corresponding to the position 31b and holding the spacer 35 at the predetermined position. However, it is very difficult to perform this work alone, and there is a problem that workability is poor.

In the case where the connecting member is provided with bent portions 32c and 33c serving as spacers, as in the case of the bracing 32 and the horizontal member 33 disclosed in Japanese Patent Application Laid-Open No. 5-116718, the spacers are connected during the connecting operation. Workability is improved because it is not necessary to hold at a predetermined position. However, the connecting member having the bent portions 32c and 33c has a problem that the processing is troublesome. In addition to the role of opposing the tightening force of the fastener, the spacer disperses the torsional force over a wide area when a force that exerts a torsional action on the column 31 via the connecting plate 31b from the connecting member acts. It is possible to play a role to reduce the influence on the column 31. However, it is difficult to increase the cross-sectional area of the bent portions 32c and 33c, and the bent portions 32c and 33c can hardly expect the effect of reducing the effect of the torsional force on the support.

SUMMARY OF THE INVENTION The present invention has been made in view of the above problems, and has as its object to provide a connecting member having an opening extending in the longitudinal direction on the opening side of a main body of a support column between the side walls of the end portion.

[0016]

DESCRIPTION OF THE PREFERRED EMBODIMENTS One embodiment of the present invention will be described below with reference to FIGS. FIG. 2 is a side view of a state in which a strut as a connecting member is connected to the support column, as viewed from a direction along the connecting direction of the rack. FIG. 3A is a cross-sectional view taken along line AA of FIG. FIG. 3B is a sectional view taken along line BB of FIG. 2.

As shown in FIG. 3 (b), a column 1 constituting a rack is composed of a flat U-shaped main body 2 and side walls 2a of the main body 2.
A pair of tapered portions 3 integrally formed so as to be continuous with
And a pair of connecting plate portions 4 integrally formed so as to be continuous with the tapered portion 3. That is, the column 1 is formed in a partially opened state.

The tapered portion 3 is formed so that its width gradually decreases from the main body 2 side to the protruding side. Therefore,
The connecting plate portion 4 and the tapered portion 3 are continuous so as to form an obtuse angle. The connecting plate portion 4 is formed so as to extend in parallel with each other at a predetermined interval smaller than the width of the main body 2, that is, the interval between the side walls 2a, and has a lip 5 bent outward at a right angle at the tip. The interval between the two connecting plate portions 4 is set to an interval in which a brace (lattice) 6 as a connecting member constituting the rack and an end of a horizontal member (not shown) can be inserted. The connecting plate portion 4 is formed with a connecting hole 4a used when connecting the ends of the braces 6 or the horizontal members. The column 1 is formed by bending (roll forming) a metal plate (for example, a steel plate).

As shown in FIGS. 1A and 3A,
The brace 6 is formed in a substantially U-shaped cross section, and the gap between the outer surfaces of the side walls 6a is formed to be substantially the same as the gap between the two connecting plate portions 4a. The front ends of the side walls 6a are bent inward at right angles toward the inside. At both ends (only one side is shown) of the brace 6, connecting holes 6b are formed at opposing positions of the side walls 6a, and a pair of insertion holes 7 are formed in a wall 6c sandwiched between the side walls 6a. I have. The two insertion holes 7 are formed in parallel with each other at a distance larger than the diameter of the hole 6b and at a position sandwiching an imaginary plane passing through the center of both holes 6b and orthogonal to the wall 6c and orthogonal to the longitudinal direction of the strut 6. In addition, a notch 8 extending from the end of the brace 6 to a position closer to the center side from a position facing the insertion holes 7 is formed at the tip of the side walls 6a. Note that the horizontal members are similarly configured. The bracing 6 and the horizontal member are also formed by bending a metal plate (for example, a steel plate).

As shown in FIGS. 1 (a) and 1 (b), the spacer 6 and the spacer 9 which is used by being assembled to the end of the horizontal member are bent into a substantially U-shaped cross section. The main body 10 includes a pair of support pieces 10a having a width W substantially equal to the distance between the side walls 6a. The interval between the two support pieces 10a is formed to be slightly wider than the interval between the insertion holes 7 formed in the wall 6c of the brace 6, and an insertion portion 11 that can be inserted into the insertion hole 7 is integrally formed at the tip of each support piece 10a. ing. That is, the main body 10 is bent and formed into a shape that can be inserted between the side walls 6a so that the fastener is disposed between the two support pieces 10a when the spacer 9 is mounted on the brace 6 of the spacer 9.

The width of the insertion portion 11 is shorter than the length of the insertion hole 7. Accordingly, the width of the insertion portion 11 is smaller than the width W of the main body portion 10, and the insertion portion 11 can be inserted into the insertion hole 7 until the tip of the support piece 10 a contacts the inner surface of the wall 6 c of the strut 6. In each insertion portion 11, in a state where the insertion portion 11 is inserted into the insertion hole 7 so as to penetrate the brace 6 from inside to outside, the brace 6 of each insertion portion 11 is provided.
A protrusion 12 that engages with the brace 6 and restricts separation of the spacer 9 from the brace 6 is formed on the side that protrudes from the brace 6.
The projection 12 is formed at a position where the tip of the support piece 10a is in contact with the inner surface of the wall 6c and is in a regulated state to engage with the outer surface of the wall 6c.

In this embodiment, the distal end surface 10b of the support piece 10a is positioned on the strut 6 of the spacer 9 while the insertion portion 11 is inserted through the insertion hole 7 until the projection 12 is positioned outside the strut 6. A positioning unit for positioning is configured.
The convex portions 12 are formed by pressing the insertion portion 11 so as to be convex outward.

When the column 1 is used in a rack used in an automatic warehouse, engaging holes (both not shown) for engaging the engaging claws of the load receiving shelf are provided on both side walls 2a of the main body 2. It is formed at a pitch. When the column 1 is used for a pallet rack, gussets fixed to both ends of a beam installed between the columns 1 arranged in the direction of the rack are provided on a wall sandwiched between both side walls 2a of the main body 2. Mounting holes (both not shown) for locking the pawls are formed at a predetermined pitch.

Next, an operation procedure for connecting a connecting member such as a brace 6 to a column using the spacer 9 configured as described above and the operation of the spacer 9 will be described. The column 1 is erected at a predetermined position along the row direction of the rack (the left-right direction in FIG. 2) with the connecting plate portions 4 facing each other. When connecting the brace 6 to the column 1, first, a spacer 9 is attached to the end of the brace 6.
Attach. The mounting work of the spacer 9 is carried out by holding the main body 10 of the spacer 9 so that the insertion portion 11 is opposed to the insertion hole 7, and the both end surfaces of the support piece 10 a are the side walls 6 a of the brace 6.
Push in with sliding contact with. When the main body 10 is further pushed in from the state where the insertion portion 11 is inserted through the insertion hole 7 to a position where the projection 12 is engaged with the insertion hole 7, both support pieces 10 a slightly bend inward each other, and the projection 12 is inserted. It passes through the hole 7.
When the convex portion 12 passes through the insertion hole 7, the bending of the two support pieces 10a is restored, and the convex portion 12 engages with the outer surface (upper surface) of the wall 6c,
The distal end surface 10b of the support piece 10a is engaged with the inner surface (lower surface) of the wall 6c, and the detachment from the brace 6 is restricted with the spacer 9 positioned.

Next, in a state where the end of the brace 6 is inserted between the two connection plate portions 4 at a position where the hole 6b of the brace 6 corresponds to the predetermined hole 4a of the connection plate portion 4, The bolt 13 is inserted into the connecting plate 4 so as to penetrate the holes 4a and 6b. Then, a nut 14 is screwed to the tip end of the bolt 13, and the bracing 6 and the connecting plate 4 are tightened and fixed to each other by the bolt 13 and the nut 14. Bracing 6
Are obliquely connected to the column 1 so as to form a predetermined angle. In this state, the bolt 13 is disposed between the two support pieces 10a. In the same manner, each of the horizontal members is connected to each of the connecting holes 4 with its ends inserted between the connecting plate portions 4.
The bolts 13 and the nuts 14 penetrate through the shaft 1a and the like, and are fixed so as to be orthogonal to the column 1, that is, horizontally.

The bolt 13 of this embodiment has a sleeve portion 13a which is continuous with the head, unlike ordinary bolts. Also, unlike the ordinary nut, the nut 14 has a sleeve portion 14a on the side facing the head of the bolt 13 in a state of being screwed to the bolt 13, and the sleeve portions 13a, 14a
Are attached so as to penetrate the holes 4a and 6b.

The spacer 9 disperses the torsional force over a wide area when the connecting member exerts a torsional action on the column 1 via the connecting plate portion 4 in addition to the role of opposing the tightening force of the fastener. It serves to reduce the influence on the support 1. At this time, the influence of the torsional force on the column 1 is reduced as the area of the support piece 10a at the portion in contact with the side walls 6a is increased.

This embodiment has the following effects. (1) The spacer 9 attached to the end of the connecting member (for example, the bracing 6) is formed on a wall where the insertion portion 11 provided at the tip of the support piece 10a is sandwiched between both side walls at the end of the connecting member. The projections 12 formed in the insertion portions 11 are engaged with the connection member on the side protruding from the wall to regulate the spacer 9 from being detached from the connection member.
Therefore, a connecting member having an opening extending in the longitudinal direction is provided on the opening side of the main body of the column 1 with the fasteners (the bolt 13 and the nut 14) with the spacer 9 interposed between the side walls 6a at the ends. Workability at the time of the connecting operation of connecting through the intermediary can be improved.

(2) The spacer 9 is formed separately from the connecting member (for example, the brace 6), and is mounted on the connecting member in a state where the spacer 9 is prevented from being separated from the connecting member via the insertion portion 11 and the convex portion 12. You. Therefore, compared to a configuration in which the bent portion serving as a spacer is integrally formed at the end of the connecting member,
It is easy to use the spacer 9 having a large cross-sectional area, and when a force for applying a twisting action to the support 1 from the connecting member via the connecting plate portion 4 is applied, the torsional force is dispersed over a wide area to thereby provide the support 1 with a large area. Can play a role in reducing the impact on the environment.

(3) In the state where the insertion portion 11 is inserted through the insertion hole 7 until the projection 12 is positioned outside the wall 6c, a positioning portion (for positioning the spacer 9 with respect to the connecting member (for example, the strut 6)). The tip surface 10b) is the main body 1
0 is formed. Therefore, since the spacer 9 is mounted in a state where it is positioned with respect to the connecting member, the connecting workability of the connecting member is further improved.

(4) Since the convex portions 12 are formed on the insertion portions 11 so as to be outwardly convex by press working, the formation of the convex portions 12 is simplified. (5) The insertion portion 11 is formed to have a width smaller than that of the support piece 10a, and the distal end face 10b of the support piece 10a forms a positioning portion. Therefore, formation of the positioning portion is simplified.

(6) The bolt 13 having the sleeve portion 13a and the nut 14 having the sleeve portion 14a are used, and the connecting plate portion 4 and the connecting member (with the sleeve portions 13a, 14a passing through the holes 4a, 6b). Since the bracing 6 is fastened and fixed, the cross-sectional area of the portion that bears the shearing force acting on the bolt 13 from the connecting member increases, and it becomes easy to secure sufficient shear strength.

(7) Since the nut 14 having the sleeve portion 14a is used, even if the length of the portion protruding outside the connecting plate portion 4 is the same as when a normal nut is used,
Since the length of the portion where the nut 14 is screwed with the bolt 13 is increased, the tightening force is increased, and the holding force of the spacer 9 and the connecting plate portion 4 on the connecting member (brace 6, etc.) is increased. Therefore, the connecting member is connected to the connecting plate portion 4 in FIG.
When a force in the direction perpendicular to the connecting plate portion 4 indicated by an arrow in FIG. 2B, that is, a force that imparts a twisting action to the column 1 is applied, the two connecting plate portions 4 share the force in an even state. Therefore, the column 1 is less likely to be plastically deformed. That is, when a force that exerts a twisting action on the column 1 from the coupling member via the coupling plate portion 4 acts, the influence of the torsion force on the column 1 is reduced.

(8) When ordinary bolts and nuts are used, a part of the portion protruding outside the connecting plate portion 4 protrudes from within the width of the column 1 (the distance between the outer surfaces of both side walls 2a). As a result, the effective frontage becomes narrower by that much, and the storage efficiency of the rack deteriorates. However, the sleeve part 14
By using the nut 14 having a, the portion of the bolt 13 and the nut 14 protruding outside the connecting plate portion 4 fits within the width of the column 1, and the rack storage efficiency is improved.

The embodiment is not limited to the above, and may be embodied as follows, for example. The shape of the spacer 9 is not limited to the shape of the above-described embodiment. The support piece 10a and the insertion portion 11 are formed to have the same width, and the wall 6c of the bracing 6 has the same length as the interval between the side walls 6a. The insertion hole 7 may be formed. In this configuration, there is no function of positioning the spacer 9 at a predetermined position with respect to the brace 6, but the spacer 9 has the projection 12 formed on the wall 6 of the brace 6.
The engagement with the outer surface of c is maintained in a state in which detachment from the brace 6 is restricted. Therefore, when the bolt 13 is inserted into the holes 4a and 6b with the connecting plate portion 4 and the holes 4a and 6b of the brace 6 facing each other at the time of connecting the brace 6 to the column, the nut 14 is tightened. By arranging the position of the spacer 9 at a predetermined position and tightening the nut 14,
The spacer 9 is fastened and fixed between the side walls 6a of the brace 6 in a state where it is arranged at a predetermined position.

In the case where the support piece 10a and the insertion portion 11 are formed to have the same width, as shown in FIG.
A convex portion 15 as a positioning portion may be formed at a position spaced from the convex portion 12 by a predetermined distance corresponding to the thickness of the wall 6c. In this case, the protrusion 15 engages with the inner surface of the wall 6c and the movement of the spacer 9 is restricted in a state where the insertion portion 11 is inserted into the insertion hole 7 to a position where the protrusion 12 projects outside the wall 6c. Then, the positioning of the spacer 9 with respect to the brace 6 is performed.

The shape of the projections 12 and 15 is not limited to a circle, but may be another shape or an elongated projection. The protrusions 12 and 15 are not limited to press working, and may be formed of, for example, welded metal by welding. In addition, the convex portion 15 as the positioning portion may be formed by bending a part of the tip of the support piece 10a.

The shape of the main body 10 is not limited to a U-shaped cross section. For example, the portion sandwiched between the support pieces 10a is substantially U-shaped with an arc shape, or an inverted M-shape as shown in FIG. And so on. Further, the shape of both support pieces 10a is not limited to a flat plate, and may have a bent portion in the middle. In the case of an inverted M-shape or a bent portion, the area of the portion where the main body 10 abuts on the side wall of the connecting member is larger than that of the flat supporting piece 10a having the same distance from the base end to the front end. In the event of an earthquake, the effect of the torsional force transmitted to the rack column 1 via the braces 6 can be further reduced.

The shape of the connecting member may be a shape having an opening extending along the longitudinal direction, and may be a shape in which the ends of both side walls 6a of the brace 6 are straight. In this case, it is not necessary to form the notch 8 at the end of the side wall 6a, and the processing of the connecting member is simplified accordingly.

The bolt 13 and the nut 14 used for connecting the connecting plate portion 4 to the connecting member such as the bracing 6 are both provided with a sleeve portion. As shown in FIG. A combination of the bolt 13 having no sleeve and the nut 14 having the sleeve portion 14a may be used. Also in this case, even when the distance between the two connecting plate portions 4 is large, the bolt 13 and the nut 14 can be increased in the tightening force by the bolt 13 and the nut 14 without protruding outside the both side walls 2a of the column 1.

As the bolts and nuts used for connecting the connecting plate portion 4 to the connecting members such as the braces 6, bolts and nuts having no sleeve portion may be used. Also,
A rivet may be used as a fastener used for connecting the connecting plate portion 4 and the connecting member.

The shape of the column 1 is not limited to that of the embodiment, and the connecting plate 4 is not provided with the tapered portion 3 and the side wall 2 is not provided.
The shape in which the connecting plate portion 4 is formed so as to be continuous with the wall bent at a right angle from the tip of “a”, or the shape without the lip 5 may be used.

The connecting member on which the spacer 9 is mounted is
Post 1 for racks of automatic warehouses or pallet racks
The present invention can be applied not only to those used for connection with the support members, but also to those used for connection to the support members of all structures using the support members having openings. Also, the connecting member on which the spacer 9 is mounted and the connecting plate portion 4 of the column are connected at least to the sleeve portion 1.
Similarly, the connection structure in which the nut 14a is tightened and fixed using the nut 14a can be applied to the connection structure between the support and the connection member of all structures using the support having the opening.

The inventions (technical ideas) other than those described in the claims which can be grasped from the embodiment will be described below together with their effects. (1) In the invention according to claim 2, the insertion portion is formed to have a width smaller than that of the support piece, and the positioning portion is formed by a distal end surface of the support piece.

And a connecting structure for connecting a supporting member and a connecting member using a nut having a sleeve portion extending to the inside of a side wall of the nut. In this case, even if the length of the portion protruding outside the connecting plate portion is the same as when a normal nut is used, the length of the portion where the nut is screwed to the bolt becomes longer, so the tightening force increases and the spacer In addition, the holding force of the connecting member by the connecting plate portion is increased. And when the force which gives a torsion effect to a support | pillar from a connection member via a connection plate part acts, the influence of a torsion force on a support | pillar decreases.

(3) In the invention described in (2), the bolt also has a sleeve portion, and each of the sleeve portions of the bolt and the nut has a connection hole formed in the side wall of the connection plate portion and the connection member. The connecting plate portion and the connecting member are fastened and fixed in a state of passing through. In this case, the cross-sectional area of the portion that bears the shearing force acting on the bolt from the connecting member increases, and it becomes easy to secure sufficient shear strength.
