Embodiment Construction

[0011] The present invention will be described below in conjunction with the accompanying drawings and examples.

[0012] like figure 1 As shown, the assembled prestressed aluminum alloy single-layer reticulated shell structure in this example includes cables 4 , rods 1 , and nodes 8 . The new plate joint 8 used in this structure includes H-shaped bar 1 , upper disc cover 2 , lower disc cover 3 , stay cables 4 , and bolts 7 .

[0013] In this node 8, the upper flange of the H-shaped steel member 1, the upper disc cover 2 and the bolt holes 6 must correspond; the lower flange of the H-shaped steel member 1, the lower disc cover 3 and the bolt holes 6 must correspond ; The bolt holes 6 of the cable 4 and the upper disk cover plate 2 must correspond. When installing the new plate type node 8, first connect the H-shaped steel rod 1 with the upper disc cover 2 and the lower disc cover 3 with bolts 7, and then connect the cable 4 with the upper disc cover 2 and the diagonal The u...

Abstract

The invention provides an assembled type prestressed aluminum alloy single-layer latticed shell structure. The structure comprises H-shaped aluminum rod parts and plate type pitch points; the H-shaped aluminum rod parts are interconnected through the plate pitch points to form a quadrilateral surface mesh; a pulling cable is arranged on each diagonal line of the quadrilateral mesh; the pulling cables are connected with the quadrilateral surface mesh through the plate type pitch points, so as to form the assembled type prestressed aluminum alloy single-layer latticed shell structure. With the adoption of the assembled type prestressed aluminum alloy single-layer latticed shell structure, the quantity of steel used and the difficulty at the structure construction are obviously reduced; the weakening effect of a bolt is reduced by 33%, so that the bearing capacity of the pitch points is improved.

Description

technical field [0001] The invention relates to a novel aluminum alloy single-layer reticulated shell structure, more specifically, relates to a novel bolt-assembled prestressed aluminum alloy single-layer reticulated shell structure. Background technique [0002] Aluminum alloy spatial grid structure is a new type of spatial grid structure developed rapidly in recent years. With its good corrosion resistance and high strength-to-weight ratio, it has been widely used in coal, chemical, electric power and other fields. At present, the commonly used grid forms include H-type aluminum single-layer reticulated shell structure and Frentier small double-layer aluminum alloy grid structure, but because the elastic modulus of aluminum alloy material is only one-third of that of steel, it is stable. Poor performance makes it difficult to give full play to the strength of structural materials and increases the construction cost of the structure. At the same time, welding will have a s...
