Abstract

The utility model provides a kind of prefabricated PC aluminium alloys single-layer latticed shell, comprise H type aluminium rod member and gusset-type joint, H type aluminium rod member is interconnected to form quadrangle surface mesh by gusset-type joint, each diagonal of quadrilateral mesh arranges a drag-line, drag-line is connected by gusset-type joint with quadrangle surface mesh, thus forms prefabricated PC aluminium alloys single-layer latticed shell.The utility model significantly reduces consumption and the structure construction difficulty of steel, and reduces 33% due to the weakening effect of bolt, and the bearing capacity of node also increases.

Description

A kind of prefabricated PC aluminium alloys single-layer latticed shell
Technical field
The utility model relates to a kind of novel aluminum alloy single-layer latticed shell, more particularly, relates to a kind of novel bolts assemblies formula prestressed aluminum alloy single-layer latticed shell.
Background technology
Aluminium alloy space network is a kind of new spatial network developed rapidly in recent years, and the corrosion resistance good by means of it and higher strength-to-weight ratio, be used widely in fields such as coal, chemical industry, electric power.Grid configuration conventional at present has H type aluminum monolayer latticed shell structure and Fo Lundier little Double-level Reticulated aluminium alloys network, but because aluminum alloy materials modulus of elasticity only has 1/3rd of steel, therefore its less stable, strength of structural materials is made to be difficult to give full play to, add the construction cost of structure, welding simultaneously can make a significant impact aluminum alloy material, therefore aluminum current alloy spatial mesh structure mostly is bolt connection, as each node of H type aluminum monolayer aluminum alloy latticed shell structure needs connection 6 rod members, each rod member needs 16 bolts usually, each node needs 96 bolts, therefore require higher to construction precision.In order to improve the stability of single-layer latticed shell and reduce difficulty of construction, the utility model proposes novel bolts assemblies formula prestressed aluminum alloy single-layer latticed shell.
Utility model content
In order to overcome deficiency of the prior art, the utility model provides a kind of novel fabricated prestressed aluminum alloy single-layer latticed shell.Compared with traditional structure, this new structure can save rod member and the bolt quantity of 33%, significantly reduces consumption and the structure construction difficulty of aluminium, and reduces 33% due to the weakening effect of bolt, and the bearing capacity of node increases.The technical solution of the utility model is as follows:
A kind of prefabricated PC aluminium alloys single-layer latticed shell, comprise H type aluminium rod member and gusset-type joint, H type aluminium rod member is interconnected to form quadrangle surface mesh by gusset-type joint, it is characterized in that, each diagonal of quadrilateral mesh arranges a drag-line, drag-line is connected by gusset-type joint with quadrangle surface mesh, thus forms prefabricated PC aluminium alloys single-layer latticed shell.
Preferably, described gusset-type joint comprises disk cover plate and lower disc cover plate, H profile steel rod member top flange is bolted on disk cover plate, and H profile steel rod member bottom flange is bolted on lower disc cover plate, then forms quadrangle surface mesh; Upper disk cover plate and lower disc cover plate are provided with drag-line connecting hole, for the end of drag-line is bolted on upper disk cover plate or lower disc cover plate, the upper disk cover plate being positioned at the adjacent gusset-type joint of on quadrilateral mesh diagonal two is coupled together by a drag-line, and its lower disc cover plate is coupled together by another drag-line.
The beneficial effects of the utility model are, compared with traditional aluminium alloys single-layer lattice shell, on each node of this novel aluminium alloys single-layer latticed shell, six rods becomes four, rod member and the bolt quantity of 33% can be saved, significantly reduce consumption and the structure construction difficulty of steel, and because the weakening effect of bolt reduces 33%, the bearing capacity of node also increases.Meanwhile, replace rod member that structure can be made to seem slimmer and more graceful with drag-line.

Fig. 2 is node schematic diagram of the present utility model;
Fig. 3 is node assembling drawing of the present utility model;
In figure, 1:H type rod member, 2: upper disk cover plate, 3: lower disc cover plate, 4: drag-line, 5: drag-line connecting hole, 6: bolt hole, 7: bolt, 8: node.
Detailed description of the invention
Below in conjunction with accompanying drawing and example, the utility model is described.
As shown in Figure 1, this example prefabricated PC aluminium alloys single-layer latticed shell, comprises drag-line 4, rod member 1, node 8.Be applied in the New-type plate node 8 in this structure, comprise H type rod member 1, upper disk cover plate 2, lower disc cover plate 3, drag-line 4, bolt 7.
H profile steel rod member 1 top flange in this node 8, upper disk cover plate 2 and bolt hole 6 must be corresponding; H profile steel rod member 1 bottom flange, lower disc cover plate 3 and bolt hole 6 must be corresponding; The bolt hole 6 of drag-line 4 and upper disk cover plate 2 must be corresponding.Carry out New-type plate node 8 when installing, first H profile steel rod member 1 bolt 7 is connected with upper disk cover plate 2 and lower disc cover plate 3, the upper disk cover plate of drag-line 4 with upper disk cover plate 2 and diagonal positions node is coupled together.
