Structural member connection system

A storage rack system constructed to support pallets loaded with goods, comprising:

• a horizontal beam extending in a horizontal direction, the horizontal beam having a vertical wall extending in a vertical direction and a height in the vertical direction of about 3, about 3.5, or about 4 inches, and a bolt receiving hole through the vertical wall;
• a structural support having a central supportive portion having a first end portion and a second end portion, the first end portion extending to a connection end having a connection flange extending in a downward direction from the connection end, the connection flange having a first, a second, and a third bolt receiving hole therethrough, each a different distance from a junction of the connection end to the connection flange, and the first hole through the connection flange overlaps the hole through the vertical wall when the vertical wall is about 3 inches, the second hole overlaps the hole through the vertical wall when the vertical wall is about 3.5 inches, and the third hole overlaps the hole through the vertical wall when the vertical wall is about 4 inches in height;
• a bolt attaching the structural support to the horizontal beam, the bolt having a threaded portion, a head portion, and a key structure between the threaded portion and the head portion, the bolt extending through the holes through the horizontal beam and the connection flange;
• the hole through the horizontal beam or the connection flange having a locking shape to engage the key structure and resist twisting of the bolt with respect to the locking shaped hole;
• and
• the key structure configured to interlock with the locking shaped hole through the connection flange or the horizontal beam and resist rotation of the bolt with respect to the connection flange or horizontal beam.

A storage rack system constructed to support pallets loaded with goods, comprising:

• a horizontal beam extending in a horizontal direction, the horizontal beam having a vertical wall extending in a vertical direction, and a bolt receiving hole through the vertical wall;
• a structural support having a supportive portion having a first end portion, a second end portion, and a central portion therebetween, the first end portion extending to a connection end, and a connection flange extending in a downward direction from the connection end, the connection flange having a bolt receiving hole therethrough;
• a bolt attaching the structural support to the horizontal beam, the bolt having a threaded portion, a head portion, and a key structure between the threaded portion and the head portion, the bolt extending through the bolt receiving holes of the horizontal beam and the connection flange;
• the bolt receiving hole through the horizontal beam or the connection flange having a locking shape to engage the key structure and resist twisting of the bolt with respect to the locking shaped hole;
• the key structure configured to interlock with the locking shaped bolt receiving hole through the connection flange or the horizontal beam and resist rotation of the bolt with respect to the connection flange or horizontal beam;
• wherein a top surface of the central portion of the supportive portion defines a first plane, the first end portion slopes downward from the first plane, and a top surface of the first end portion defines a second plane and a third plane, the second plane closer to the central portion than is the third plane and the second plane forms a larger angle downward from the first plane than the angle between the third plane and the first plane.

A structural support, comprising:

• a first end portion, a second end portion, and a central portion therebetween, the central portion extending in a horizontal direction and having a top surface defining a first plane;
• the first end portion extending from the central portion to a connection flange at a first end of the first end portion, the first end portion sloping downward from the first plane, wherein the first end of the first end portion is offset downward from the first plane;
• the connection flange substantially perpendicular to the first plane and having a connection hole in the shape of a polygon therethrough;
• and
• a top surface of the first end portion defines two sloping surfaces, each at a different angle with respect to the first plane.

A method of assembling a storage rack constructed to support pallets of goods, comprising:

• attaching a structural support to a hole through a vertical wall of a horizontal beam oriented in a horizontal direction, the horizontal beam having an upper surface, a lower surface and the vertical wall from the lower surface to the upper surface, the horizontal beam having a height of about 3 to 4 inches;
• the structural support having a connection flange with a thickness of at least about 1/16 inch and having a first and a second hole therethrough, overlapping the hole through the horizontal beam with the first hole when the beam has a height of 3 inches and overlapping the hole through the horizontal beam with the second hole when the beam has a height of 4 inches;
• inserting a bolt through the hole in the vertical wall and the overlapping hole in the connection flange, the bolt having a threaded portion, a head portion, and a key structure between the threaded portion and the head portion;
• the hole through the vertical wall or the connection flange having a polygon shape;
• interlocking the key structure with the polygon shaped hole through the connection flange or vertical wall;
• and
• tightening a nut over the bolt, the key structure preventing rotation of the bolt with respect to the connection flange or horizontal wall as the nut is tightened.
