The bearing performance of the goods shelf is also closely related to the structural size, the structural form, the material thickness and the connection mode between the upright columns, so that the integral structure of the goods shelf is very important. The utility model discloses on traditional horizontal bracing nodal connection scheme basis, change horizontal bracing into the preparation of the clod wash thin wall C shape section bar that has high ability of shearing to adopt two nodal connections with the stand, horizontal bracing is V or W shape with single and arranges between stand and stand, makes the goods shelves structure more reliable and more stable.

The utility model discloses a: the method comprises the following steps: the cross section of the cross diagonal brace formed by rolling steel is C-shaped, two ends of the cross diagonal brace are provided with rectangular notches on opposite sides of a C-shaped opening, two end openings of the cross diagonal brace and the vertical direction of the notches are provided with a pair of round holes, the cross diagonal brace and the upright post are fixed by the bolts through fixing holes in the upright post, then the cross diagonal brace penetrates through the pair of round holes in the cross diagonal brace and is screwed and fixed through a pad and a ring nut, two ends of the cross diagonal brace are connected in the same way, and the cross beam is inserted into the upright post through a hook and fixed with the upright post to enable the upright post, the cross beam and the cross diagonal brace to be connected into a whole.

The cross diagonal braces are arranged between the upright posts in a V or W shape by a single brace, and the cross beam is inserted into the hook holes of the upright posts through the hooks and fixed with the upright posts. Thereby the upright post, the cross beam and the cross diagonal bracing are connected into a whole.

The thickness of the plate of the transverse diagonal bracing is 1.5-1.8 mm, and the height-width ratio of the cross section is 1: 3. the size of the rectangular gap at the flat two ends of the transverse diagonal brace is 12.5mm X80 mm. The diameter of the round holes at the two ends of the transverse diagonal bracing is 11-15 mm.

The bolt is a hexagon socket head cap screw, and the diameter is 10-14 mm.

The utility model discloses the advantage has abandoned traditional horizontal bracing scheme, adopts the preparation of the thin wall C shape section bar of the clod wash that has high shear capacity, and horizontal bracing adopts the dual node to be connected with the stand, is V or W shape and distributes and fix with the stand between stand and stand, makes stand and crossbeam, horizontal bracing fuse to make the goods shelves structure more reliable and more stable, reduced the cost and improved storage efficiency.

Detailed Description

The embodiments of the present invention will be further explained with reference to the drawings.

With reference to figures 1 to 3 of the drawings,

the embodiment comprises a vertical column 1, a transverse diagonal brace 2, a gasket, a bolt 4 and a nut. The transverse diagonal bracing 2 is formed by cold-bending and rolling steel. The thickness of the plate of the transverse diagonal brace 2 is 1.5-1.8 mm, and the thickness of the plate is 1.5mm in the embodiment. The cross section of the cross diagonal brace 2 is C-shaped, and the height-width ratio of the cross section of the cross diagonal brace 2 is 1: 3. rectangular gaps are formed in the two ends of the transverse diagonal brace 2 and are arranged on the opposite sides of the C-shaped opening, and the size of each rectangular gap is 12.5mm X80 mm. A pair of round holes is arranged in the vertical direction of the openings at the two ends of the horizontal inclined strut 2 and the gap. The diameter of the round hole is 11-15 mm. This embodiment is 11 mm. The cross diagonal brace 2 and the upright post 1 are fixed by a bolt 4 which passes through a fixing hole on the upright post 1, then passes through a pair of round holes on the cross diagonal brace 2 and is screwed and fixed by a washer and a nut. The bolt 4 is a hexagon socket head cap screw, and the diameter is 10-14 mm. This embodiment is 10 mm. The two ends of the cross diagonal brace 2 are connected the same. The horizontal diagonal bracing 2 is arranged between the upright posts 1 in a V or W shape by a single support, the horizontal diagonal bracing 2 is in a V shape and is connected with the upright posts in a double node manner, and the cross beam 3 is inserted into a hook hole of the upright post 1 through a hook and is fixed with the upright post 1, so that the upright post 1, the cross beam 3 and the horizontal diagonal bracing 2 are connected into a whole.

The transverse diagonal bracing 2 is used as a main stress supporting component of the goods shelf, the load borne by the upright post 1 is increased along with the increase of the height of the goods shelf and the increase of the layer number, certain internal stress is generated in the production and processing process of the upright post, and the stress condition is complex in the using process. The loading performance of the shelf is also closely related to the structural size, the arrangement mode and the material thickness of the cross section of the cross brace 2 and the connection mode of the upright post 1 and the cross brace 2, so that the design and selection of the cross brace 2 become the focus of the stability of the whole shelf. The load-bearing capacity of the pallet is directly related to the safety of the structure and the economy of use.
