Description

A single-belt corridor of a square steel pipe truss structure

technical field

The utility model relates to a belt corridor structure, in particular to a single belt corridor with a square steel pipe truss structure.

Background technique

The belt corridor is a common protection system for belt conveyors used in industrial transportation. There are roughly two structural types in the industrial belt corridor: one is the corridor of the reinforced concrete support supporting the brick-concrete structure, and the span of the corridor of this structure is It is small, occupies a large area, is heavy and has relatively poor seismic performance. In addition, it has the disadvantages of rough shape and long construction period. The other is a corridor in the form of steel structure. At present, angle steel or open section steel (H-shaped steel and I-shaped steel) are generally used to form a truss skeleton in steel structure corridors, and supports are set on four sides to form corridors with a stable support system; Compared with the brick-concrete structure corridor, the corridor has the advantages of large span, small footprint, good seismic performance, beautiful appearance, and short construction period, so it has been widely used. However, in the design process, because the support system mainly determines the section size according to the slenderness ratio, the steel consumption is large and the material utilization rate is low. In addition, various types of steel need to be connected by gusset plates, which not only increases the amount of steel used, but also has a cumbersome structure, heavy structure, and complicated fabrication and installation.

The upper chord and the lower chord in the side truss are arranged in parallel; the side webs include webs and diagonal webs, wherein the webs are vertically arranged between the upper chord and the lower chord, and diagonal webs are arranged between the webs; the wall skin The purlins are set parallel to the top and bottom chords.

The roof purlins in the roof system are arranged parallel to the upper chord, and the roof support is composed of roof diagonal braces and roof short braces; roof beams are arranged between the upper chords on both sides and the corresponding positions of the webs, and the upper chords, corresponding side roof purlins and corresponding Roof oblique braces are set between adjacent roof beams, and short roof braces are set between adjacent roof purlins.

The floor beams are composed of floor main beams and floor secondary beams, the floor main beams are arranged between the lower chords on both sides corresponding to the web members, and a plurality of floor secondary beams are arranged between adjacent floor main beams , the floor secondary beam is set parallel to the bottom chord.

Compared with the prior art, the beneficial effects of the utility model are:

1) The rods of the main structure are all made of square steel pipes. Compared with the traditional steel structure corridor, the materials on the same rod section are evenly distributed around the neutral axis, so that the rod section has good compressive, bending and torsional bearing capacity at the same time And greater rigidity, so the overall strength is high and the number of rods is small;

2) Each bar can be connected without gusset plate at the node, which is simple in structure and convenient in construction;

3) The structure is simple and light, saving the amount of steel used, and the facade is simple and beautiful, which is convenient for construction.
