Problems solved by technology

Among them, the above-mentioned upper and lower chords, webs, and secondary trusses are all single members. When used in large-span structures, the cross-sectional size of the members needs to be increased to maintain sufficient rigidity, thereby increasing the foundation cost.

Embodiment Construction

[0019] It should be noted that, in the case of no conflict, the embodiments in the present application and the features in the embodiments can be combined with each other. The present invention will be described in detail below with reference to the accompanying drawings and examples.

[0020] Such as figure 1 and figure 2 As shown, the embodiment of the present invention provides a kind of prestressed grid industrial material yard shed, including the upper chord, the lower chord, the web and the secondary truss, and the upper chord, the lower chord, the web and the secondary truss are all composed of at least one rod assembly 10, and each rod assembly 10 includes a plurality of rod units.

[0021] Changing the upper chord, lower chord, web and secondary truss from a single member to a grid structure composed of multiple member units can effectively increase the stiffness of the structure itself and avoid excessive cross-section of the member as the span increases In order...

Abstract

The invention provides a prestress grid industrial material field awning. The prestress grid industrial material field awning comprises upper chords, lower chords, web members and secondary trusses which are each composed of at least one rod assembly, and each rod assembly comprises a plurality of rod units. The upper chords, the lower chords, the web members and the secondary trusses are transformed from single rods to grid structures composed of the multiple rod units, the rigidity of the structures can be effectively improved, the problem of the overlarge sections, caused by span increasing, of the rods is solved, and the basic construction cost of the structures is reduced under the overlarge span, so that the structures have better economical benefits.

Description

technical field [0001] The invention relates to a prestressed grid industrial material yard shed. Background technique [0002] The existing prestressed tube truss structure reduces the foundation force and the foundation cost by applying a certain prestress, but with the increase of the span, the section of the bar is too large, the production is difficult, and the amount of steel is large; the giant grid structure can It achieves better economy under the requirements of rigidity, strength and stability, and can realize super-large spans, but the structural column foot force is relatively large, resulting in excessively high foundation costs. [0003] The canopy structure in the prior art includes upper and lower chords, webs, and secondary trusses. The above-mentioned upper and lower chords, web members, and secondary trusses are all single members. When used in large-span structures, the cross-sectional size of the members needs to be increased to maintain sufficient rig...
