Abstract

The utility model provides a storage rack's integral type seals embracing beam, embraces the beam and is rolled the closed cavity structure who forms nineteen face of book by coil of strip cold bending, embraces the similar rectangle of cross section of beam, along the left and right bilateral symmetry of central line, embraces the roof of beam top and for crossing the overlapping of steel sheet, is equipped with a triangle-shaped recess on the lateral wall of top both sides respectively, the top lateral wall and the roof of this triangle-shaped recess are double-deck overlapping structure, the lateral wall middle part of embracing the beam both sides is equipped with a trapezoidal recess. The utility model has the advantages that adopt cold rolling technique to coil of strip processing, the loading end of cohesion roof beam distributes on the double-deck overlapping structure of cohesion roof beam, and both sides are the holding surface, and the triangle-shaped recess and the trapezoidal recess of cohesion roof beam both sides play the effect of strengthening rib. The cohesive beam made of the steel coil with the thinner wall thickness can bear larger load.

Description

Integrated closed cohesion beam of storage shelf

Technical Field

The utility model relates to a, especially a embrace roof beam is sealed to integral type of storage rack.

The utility model relates to a storage equipment, in particular to cohesion new cross-section of roof beam after theoretical analysis and performance test research

Background

The assembled steel goods shelf is one of the most widely applied structural forms in the field of modern logistics, one of the main bearing components is a beam structural component, wherein the holding beam is also the most widely applied, the application safety of enterprise products and the reliability of customer use are directly determined by a design theory and a performance verification system, the unique section structure and the connection mode determine that the stress performance is inevitably different from that of a common light rigid frame structure, and the section design is not suitable for being blindly applied to the current steel structure design specification. Therefore, a series of experimental research and theoretical analysis are carried out on the cohesive beam, the stress behavior and the failure mechanism of the structure are mastered, and a novel cohesive beam section is provided.

Disclosure of Invention

The utility model aims at the defect that exists among the prior art, the utility model provides a this storage goods shelves's integral type seals embracing beam, its characterized in that embraces the beam and is rolled the closed cavity structure who forms nineteen faces by the coil of strip clod wash, the similar rectangle of cross section of embracing the beam, along the central line left and right bilateral symmetry, it is crossing the overlapping for the steel sheet to embrace the roof portion of beam, be equipped with a triangle-shaped recess on the lateral wall of top both sides respectively, the top lateral wall and the roof of this triangle-shaped recess are double-deck overlapping structure, the loading end of embracing the beam distributes on embracing the double-deck overlapping structure of beam. The middle parts of the side walls at the two sides of the embracing beam are respectively provided with a trapezoidal groove. The two sides of the embracing beam are supporting surfaces, and the triangular grooves and the trapezoidal grooves on the two sides of the embracing beam play a role of reinforcing ribs.

The thickness of the material of the embracing beam is 1.2-2.0 mm.

The height-width ratio of the cross section of the embracing beam is 4: 1.

The utility model has the advantages that adopt cold rolling technique to coil of strip processing, the cohesion roof beam that can make the coil of strip that the wall thickness is thinner made can bear bigger load. Saving material and reducing dead weight.

fig. 4 is an assembly view of the present invention.

In the figure: 1 top, 2 side walls, 3 triangular grooves and 4 trapezoidal grooves.

Detailed Description

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

Referring to fig. 1 to 4, the embracing beam is formed by cold-bending and rolling a steel coil, and the wall thickness of the material of the embracing beam is 1.2 to 2.0mm, in this embodiment, 2.0 mm. After the steel coil is continuously rolled by a plurality of rollers, nineteen folding surfaces are formed, the cross section of the cohesive beam is similar to a rectangle, and the height-to-width ratio of the cross section of the cohesive beam is 4: 1. The embracing beam is of a closed cavity structure, and the top 1 of the embracing beam is an overlapped part where steel sheets are intersected. The left side and the right side of the cross section of the center line of the embracing beam are symmetrical, a triangular groove 3 is respectively arranged on the left side wall 2 and the right side wall 2 of the two sides of the top 1, and the upper side wall and the top wall of the triangular groove 3 on the two sides are of a double-layer overlapping structure. The bearing surfaces are distributed on the double-layer overlapping structure of the embracing beam. The middle parts of the side walls 2 at the left side and the right side of the embracing beam are respectively provided with a trapezoidal groove 4, and the two sides are supporting surfaces of the embracing beam. The triangular grooves 3 and the trapezoidal grooves 4 on the two sides of the embracing beam play a role of reinforcing ribs.

When the goods shelf is used, the end face of the embracing beam and the side face of the hanging piece are welded firmly according to the relative height required by design, the hanging teeth on the hanging piece are directly hung on the hole wall of the upright post, and the embracing beam is also horizontally arranged in the goods shelf along with the hanging tooth, so that the goods shelf can be supported.
