Abstract
The utility model relates to a cable arch structure, in particular relates to a stay-cable arch structure, and belongs to the field of steel structures. The stay-cable arch structure comprises a spatial arched truss, wherein both ends of the spatial arched truss are supported through inclined standing columns and inclined supporting rods; the inclined standing columns extend outside the spatial arched truss, and are connected and tensioned through string cables; and the bottom ends of the inclined supporting rods and the tops of the inclined standing columns are tensioned through the stay cables. The stay-cable arch structure has a simple structure, the construction precision is improved, and the construction period is shortened.
Description
Technical field
The utility model relates to a kind of rope arch structure, relates in particular to a kind of suspension cable arch structure, belongs to field of steel structure.
Background technology
The suspension cable arch structure of striding greatly of prior art is a kind of novel large span spatial structure at present, says from form of structure, strides the combination that the suspension cable arch structure is slant-pull structure and rope arch structure greatly, has both had both some characteristics, with both very big difference is arranged again.It is good to stride suspension cable arch structure overall performance greatly, reasonable stress, and structure is economical, can adapt to different plane figure and profile, has vast potential for future development.In striding the suspension cable arch structure greatly, mast and suspension cable are main bearing member, and clear and definite Path of Force Transfer makes that rope arch unit member is stressed even, can make full use of material property, makes the good mechanical performance be able to represent; And rope arch unit rolls into one the advantage of suspended-cable structure and arch structure; Drag-line need not apply very big prestressing force just can have structural stability and property handsome in appearance preferably, and gentle rope and rigid arch mutually combine, and replenish each other; Maximize favourable factors and minimize unfavourable ones; Thereby increased structural span, alleviated member dead weight, practiced thrift material usage.
But, stride suspension cable arch structure moulding novelty greatly, the design feature of stressed complicacy; Also increased the difficulty of its construction and installation greatly; Tiltedly draw system and rope arch system on the one hand and deposit to make the selection of its constructure scheme that self unique requirement arranged, the characteristic of combining structure is installed its stretching construction that should carry out rope on the other hand, also will implement to promote or lifting construction; To same large-span steel building; When the technology path of its installation was different, the construction stress approach of its structure was also different, thereby produces different construction infections.
The utility model content
The utility model mainly is to solve the deficiency that exists in the prior art, provides a kind of simple in structure, and the suspension cable arch structure of ability reduction of erection time.
The above-mentioned technical problem of the utility model mainly is able to solve through following technical proposals:
A kind of suspension cable arch structure; Comprise the space arch truss; Two ends of described space arch truss are supported with hound with oblique column mutually; Described oblique column extends to outside the arch truss of space, is connected through the string rope between two oblique columns and strains, and strains mutually through suspension cable between the top of the bottom of described hound and oblique column.
As preferably, the roof intersection of described oblique column and hound.
Easy construction.It is few to set up moulding bed quantity, and part in bulk is installed in completion on the civil engineering structure but not accomplishes on the ground, and setting height(from bottom) reduces, and installation at high altitude work significantly reduces, and installation cost is low, and installation accuracy is easy to control.Can effectively shorten the time, guarantee the duration.The employing lifting is constructed and primary structural component is in bulk combines, and does not need large-scale lifting appliance, and to not influence of civil engineering, the duration is guaranteed easily.
The utility model provides a kind of suspension cable arch structure, and is simple in structure, improves construction precision, the reduction of erection time.
Description of drawings
Fig. 1 is the structural representation of the utility model.
The specific embodiment
Pass through embodiment below, and combine accompanying drawing, do further bright specifically the technical scheme of the utility model.
Embodiment 1: as shown in Figure 1; A kind of suspension cable arch structure comprises space arch truss 1, and two ends of described space arch truss 1 are supported with hound 3 with oblique column 2 mutually; Described oblique column 2 extends to outside the space arch truss 1; 2 on two oblique columns are connected through string rope 4 and strain, and strains the roof intersection of described oblique column 2 and hound 3 mutually through suspension cable 5 between the top of the bottom of described hound 3 and oblique column 2.
Claims (2)
1. suspension cable arch structure; It is characterized in that: comprise space arch truss (1); Two ends of described space arch truss (1) are supported with hound (3) with oblique column (2) mutually; Described oblique column (2) extends to outside the space arch truss (1), is connected through string rope (4) between two oblique columns (2) and strains, and strains mutually through suspension cable (5) between the top of the bottom of described hound (3) and oblique column (2).
