Description

[Detailed Description of the Invention] [Industrial application] The present invention relates to a fixing device of a connecting rod used for connecting columns of an assembly shelf.

[Conventional technology]

2. Description of the Related Art Conventionally, assembly shelves have been installed in warehouses and the like to store products and store them. In the above-mentioned assembly shelf, a required number of columns made of channel steel are erected in the depth direction and the width direction of the assembly shelf. A connecting rod is attached horizontally or diagonally between a pair of columns facing each other in the depth direction. The above-mentioned connecting rod also has a function as a reinforcing rod, and usually both ends thereof are fixed to the column by welding. In addition, a support rod is detachably attached between a pair of columns facing each other in the width direction,
The mounting position can be changed in the vertical direction of the column. Usually, the mounting plate is attached across this support rod and the support rods attached to the other pair of opposing columns.

[Problems to be Solved by the Invention] However, when assembling the above-mentioned assembly shelf, a large number of connecting rods must be welded to the pair of columns facing each other in the depth direction, which is troublesome and troublesome.

Therefore, an object of the present invention is to provide a connecting rod fixing device capable of detachably and firmly attaching the connecting rod to the support column without welding.

[Means for Solving the Problems]

In order to solve the above-mentioned problems, the present invention has a pair of projecting walls on both sides of an opening of a strut made of channel steel with symmetrical locking holes formed at required intervals in the longitudinal direction of the strut. Pressing plates for abutting the locking metal fittings on the inner surfaces of the columns, a central plate extending from one end of the pressing plate on the projecting wall side to the inner surface of the projecting wall, and the middle of the opening, and the central plate It is composed of a tightening plate projecting outward of the opening from one end on the middle side of the opening, and a claw that engages with the locking hole is provided in the vicinity of the boundary between the central plate and the pressing plate. A structure is adopted in which a gap for inserting one end of the connecting rod is provided between the both tightening plates, and bolts are inserted through the holes formed in the connecting rod and each tightening plate and tightened with nuts.

[Action]

When a pair of locking metal fittings are fitted into the opening of the column and the claws are engaged with the locking holes of the projecting wall, the pressing plate abuts the inner surface of the column and a gap is formed between both tightening plates. It Insert one end of the connecting rod into this gap, insert bolts through the holes formed in the connecting rod and each tightening plate, and tighten them with nuts. While pressing each other, the above-mentioned pressing plate is pressed against the inner surface of the column by the rotational force about the claw, and the connecting rod is fixed in this state. The pillars are prevented from being deformed by pressing the boundary portions of the central plate and the tightening plate against each other, and the ratcheting of the locking metal fittings is prevented by pressing the pressing plate against the inner surface of the pillar. To be prevented.

Further, since the above-mentioned locking holes are formed in the length direction of the supporting column at a required interval, the locking metal fitting can be locked at any position of the supporting column.

〔Example〕

 An embodiment of this invention will be described with reference to the drawings.

As shown in FIG. 1, the fixing device of the connecting rod in the assembly shelf of the embodiment is provided with projecting walls 3 sandwiching the opening 2 on both sides of the opening 2 of the pillar 1 made of channel steel. This protruding wall 3
A symmetrical locking hole 4 is formed on the column 1 with a required interval.
Is formed in the length direction. An attachment hole 6 for attaching the support rod 20 is formed in the support wall 5 on the opposite side of the opening 2 in the length direction of the support column 1 (see FIG. 4).

The pair of locking fittings 7 are composed of a pressing plate 8, a central plate 9 and a tightening plate 10, respectively. One end of the pressing plate 8 is bent in a dogleg shape, and the bent protrusion 11 is
It is fitted in the opening 2 so as to abut the inner surface of the. A claw 12 that engages with the locking hole 4 is formed at the center of the other end of the pressing plate 8, and a center plate 9 is formed along the inner surface of the protruding wall 3 and in the middle of the opening 2 of the column 1. Pressing plate 8
(See FIGS. 2 and 3).

A semi-circular tightening plate 10 protruding from the end of the central plate 9 to the outside of the opening 2 is connected to the central plate 9. A pair of locking metal fittings 7
In the state in which is fitted into the opening 2 of the column 1, the boundary portion 13 between the central plate 9 and the tightening plate 10 is close to each other, and a gap 14 is formed between the both tightening plates 10. To be done. The gap 14 is formed so as to become larger as it gets away from the opening 2. In addition, on both tightening plates 10,
Holes 16 through which the bolts 15 are inserted are formed. One end of one or two connecting rods 17 is inserted into the gap 14 of the tightening plate 10, and the bolts 15 are inserted into the holes 18 formed in the connecting rod 17 and the holes 16 of the tightening plate 10. These are fastened with nuts 19 to fix the connecting rod 17.

When a pair of locking metal fittings 7 are fitted into the openings 2 of the columns 1 of the connecting rod fixing device in the assembly shelf having the above-mentioned structure and the claws 12 are engaged with the locking holes 4 of the protruding wall 3, the pressing plate is pressed. 8 is in contact with the inner surface of the column 1, and a gap 1 is formed between both tightening plates 10.
4 is formed. One end of the connecting rod 17 is inserted into the gap 14 to form the holes 1 formed in the connecting rod 17 and each tightening plate 10.
When the bolts 15 are inserted into the screws 6 and 18 and tightened with the nuts 19, the boundary portions 13 between the central plate 9 and the tightening plate 10 press each other, and the bent convex portions of the pressing plate 8 also. 11 is pressed against the inner surface of the column 1 by the rotational force about the claw 12, and the connecting rod 17 is fixed in this state.
The above-mentioned boundary portion 13 between the central plate 9 and the tightening plate 10 presses each other to prevent deformation of the column 1, and
The bending protrusion 11 of the pressing plate 8 is pressed against the inner surface of the support column 1 to prevent the locking metal fitting 7 from rattling.

Further, since the locking holes 4 are formed in the length direction of the column 1 with a required space, the locking metal fitting 7 can be locked at any position of the column 1.

[Effect of device]

As described above, according to the present invention, the connecting rod can be detachably and firmly attached to the pillar of the assembly shelf without welding, so that the assembly of the shelf is easy,
And there is an effect that it can be done in a short time.

Moreover, since the locking holes are formed in the length direction of the support column at a required interval, the locking metal fitting can be locked at any position of the support column.
