Description
Technical field
The utility model patent relates to a kind of node fastener, relates in particular to a kind of multiple string that is used for construction steel structure and props up the lower-chord panel point fastener of structure.
Background technology
It is a kind of novel hybridization prestressed large-span space structures system that the single-layer lattice shell and the flexible cable-strut system of rigidity are combined that existing string props up latticed shell structure, adapts to space structures large span, light-duty, stressed reasonable, succinct development trend.It has improved the resistance to overturning of top single-layer lattice shell structure on the one hand, makes structure can cross over bigger space; On the other hand, string props up latticed shell structure and has certain initial stiffness, and its design, construction forming and joint structure are compared with full flexible structures such as rope domes and obtained bigger simplification.In addition, two kinds of structural systems are cancelled out each other to the effect of bearing, make structure become self equilibrium systems, when giving full play to single-layer lattice shell structure stress advantage, can make full use of the high-strength pull resistance of rope material, the distribution of internal force of adjustment system reduces the internal force amplitude, thereby improves structure bearing capacity.And multiple string props up structure is that a kind of novel string props up the latticed shell structure form, its cable-strut system divides the primary and secondary rope, and arrange at interval, wherein the main rope termination is positioned at truss end, capital place, and the every end of inferior rope termination is positioned at truss span 1/5 place, and 1/5 place by the vertical strut in first place of two tacklines and adjacent truss end on the end node place be connected, such layout makes member stress more reasonable, system more succinctly, moulding is more attractive in appearance.But a series of problems have also been brought simultaneously, in truss string structure, difficult and the vertical strut of the prestressed cable of lower edge effectively is connected and is fastening, cause drag-line eccentric easily, increase frictional force, loss of prestress is bigger, the stressed flexing of securing member, and string props up rope, the strut of latticed shell structure, actual internal force size and the distribution and the different design of net mould component after finally causing pre-stress construction to be finished, and this will have a negative impact to the mechanical property that whole string props up structure.
Summary of the invention
The utility model mainly is to solve the deficiencies in the prior art, provides that a kind of that multiple string is propped up latticed shell structure lower edge prestressed cable is fastening and prop up the lower-chord panel point fastener of structure with multiple string that strut effectively is connected.
Above-mentioned technical problem of the present utility model is mainly solved by following technical proposals:

(2), construction cost is low.The multiple string that adopts props up the lower-chord panel point fastener simple structure, easy to operate of structure, and the construction precision height, can avoid adjusting repeatedly the resources such as time, manpower and materials of Suo Li, so construction cost reduces significantly.
(3), structure is safe in utilization.Because it is fastening to adopt steel-casting to carry out, its bearing capacity height, and can effectively prevent from when the stretch-draw of lower edge drag-line the local failure of securing member is prevented the stressed flexing of securing member, increased the safety of structure.
As preferably, the groove in the described strut connector is " ∩ " type, and the low groove in the described montant of reeving is " ∪ " type, and described cableway holder is " ⊥ " type, and the cableway face in the described duct of reeving is provided with a mao tooth.
As preferably, the radian of described groove upper end is 170 °～180 °, and the radian of described low groove is 150 °～170 °, and the low groove internal diameter is than the little 2～3mm of groove internal diameter, and the height of described hair tooth is 1～2mm.
As preferably, the sidewall of described strut connector is provided with more than one pull bar and connects otic placode, described pull bar connects otic placode and the strut connector is the shape distribution that is inclined upwardly, described pull bar connects otic placode and is provided with connecting hole, described cableway holder and strut connector are fastened by 4 groups of high-strength bolts, and 4 groups of high-strength bolts are evenly distributed on the bottom of cableway holder.
The bottom of strut connector is provided with the bolt blind hole.
As preferably, the sidewall of described strut connector is provided with a pair of pull bar and connects otic placode, and described pull bar connects otic placode and is and is dislocatedly distributed.
As preferably, the bottom of described strut connector and cableway holder is cylindric, and described cableway holder is integrated with the montant of reeving, and described strut connector and cableway holder are steel-casting.
Therefore, a kind of multiple string of the present utility model props up the lower-chord panel point fastener of structure, and is rational in infrastructure, the construction precision height, and construction cost is low, increases the steel work safety.
