Description

A kind of truss string structure of built-in oblique guy rope
Technical field
The utility model belongs to large span opens the truss string structure of string roof structure technical field, and the truss string structure of oblique guy rope is particularly set in a kind of body.
Background technology
Truss-string-structure is proposed in 1986 by Nihon University M.Saitoh professor the earliest, this structure is a kind of novel hybridization roof system that is different from traditional structure, the self-balancing combination construction that it is mainly made up of the truss member that winds up as press-bending parts, lower edge flexible cable and intermediate pressurised strut is also more successful large-span prestressed space structure body in a kind of Mixed Architecture development.
The feature of truss-string-structure is that system is simple, stressed clearly, form of structure is various, given full play to the advantage of hard and soft material, and it is simple and convenient to manufacture, transport, construct, and has therefore obtained good application.In recent years, become China's landmark building taking Pudong International Airport in Shanghai departure lounge, Guangzhou International Exhibition, Harbin International Conference and Exhibition Center, Beijing agricultural exhibition center, National Indoor Stadium as the Large-span Truss String Structure roof structure of representative.
At present, researcher in this field generally believe the force-mechanism of truss-string-structure be by lower edge flexible cable is applied prestressing force make to wind up truss member produce allowance for camber, the final amount of deflection of structure under load action reduced, and the truss that winds up that intermediate pressurised strut forms adopts arched girder or truss arch, horizontal thrust in load action lower arch is born by lower edge flexible cable, to alleviate the horizontal movement of encircleing the horizontal thrust that bearing is produced and reducing sliding support.Truss-string-structure can be brought into play high strong tensile property of wringing, and improves integrally-built stress performance, and bending component and tension member are learnt from other's strong points to offset one's weaknesses, collaborative work, thus reach self-balancing.
Although this truss-string-structure of the prior art has many advantages, but still exist several larger problems: (1) truss-string-structure is a kind of wind load sensitive structure, for modern long span building, the general truss-string-structure that adopts light Roof system, in wind load larger area or typhoon region, the situation that may occur the lax or pressurized of lower edge drag-line and deactivate under wind suction effect, its self equilibrium systems does not also exist, degree of safety is lost, so often need to be at roofing for heavily guaranteeing not loss of stability and degree of safety of structure under wind suction effect, therefore existing truss-string-structure is not suitable for the effect of wind suction, (2) in prior art, truss string structure last quarter rope ball is formed by cast steel, needs special processing, is difficult to be made into standard component, (3) truss string structure of the prior art bottom only has rope ball, and when stretch-draw, lower-chord panel point should have device control cord ball to move left and right, and guarantees that again rope ball produces displacement upwards, and construction auxiliary equipment increases, and difficulty of construction is larger.
Truss-string-structure of the prior art need to carry out at roofing standby heavy, to guarantee that negative wind screw-down structure does not lose stable and degree of safety, but adopts the standby heavy method of roofing both to increase steel using amount, the burden of heavy structure in the time that structure is born conventional vertical live load again, and truss string structure of the present utility model is furnished with oblique guy rope, tiltedly the Main Function of guy rope is exactly under the effect of wind suction, to prevent the allowance for camber that structure generation is excessive, thereby guarantee that lower edge drag-line is not lax, when another formal structure bears conventional vertical live load, tiltedly guy rope also can provide resiliency supported for truss string structure, its working mechanism is as follows: last quarter rope is forming a pre-stress system with two-way drag with oblique guy rope after pre-stretch-draw, structure is under the vertical live load effect of routine, the internal force of last quarter rope increases, for web member provides elastomeric bearing, tiltedly the internal force of guy rope reduces, in other words the internal force increment of oblique guy rope points to the upper end of oblique guy rope, this internal force increment is for resisting live load straight down, tiltedly guy rope equals to provide resiliency supported to truss string structure, under wind suction effect, last quarter rope internal force reduces, be that original part last quarter rope reduces the upper top power of web member, tiltedly the internal force of guy rope increases, the reversal deformation of structure is had to good restraining function.
2. joint structure comparison
In prior art, truss string structure last quarter rope ball is formed by cast steel, needs special processing, is difficult to be made into standard component; And the fixed pulley of truss string structure of the present utility model can be made into standard component, can be by common mechanical factory process, and expense is lower, and simple structure is easily gone.
3 construction and installation complexity comparisons:
Truss string structure of the prior art bottom only has rope ball, and when stretch-draw, lower-chord panel point should have device control cord ball to move left and right, and guarantees that again rope ball produces displacement upwards, and construction auxiliary equipment increases, and difficulty of construction is larger; And truss string structure last quarter rope of the present utility model passes through fixed pulley power transmission to node sleeve pipe, and then upper top power is passed to web member, its frictional force reduces greatly, lower node is swung originally just little, adding lower-chord panel point degree of freedom is retrained by quadrangular pyramid shape web member, when stretch-draw last quarter rope without to lower-chord panel point increase servicing unit, thereby greatly reduce operating expenses.
Therefore, the utility model compared with prior art, has advantages of that rolled steel dosage is low, cheap, structural stability is good and is applicable to wind suction load.
Summary of the invention
