The lower-chord panel point fastening device comprises a stay bar connecting piece; the side wall of the stay bar connecting piece is provided with two inhaul cable connecting lug plates and a pull rod connecting lug plate; the heads of the inhaul cable connecting lug plates are provided with inhaul cable holes; and the head of the pull rod connecting lug plate is provided with a pull rod hole. The lower-chord panel point fastening device of the cylindrical surface chord support structure has reasonable and safe structure, high construction accuracy and low construction cost.
Description
Technical field
The utility model patent relates to a kind of fastener, relates in particular to the lower-chord panel point fastener that a kind of face of cylinder string props up 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 present 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 face of cylinder string props up structure is that a kind of novel string props up the latticed shell structure form, be divided into umbrella unit and the linkage unit of umbrella between umbrella one by one under the total form, wherein the umbrella unit is the main stress unit of structure, linkage unit is a time stress unit, and each junior unit is made up of to rope and 4 pull bars 4 straight-flanked rings.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, and a kind of lower-chord panel point fastener that can make the face of cylinder string of answering strength enhancing in advance prop up structure is provided.
Above-mentioned technical problem of the present utility model is mainly solved by following technical proposals:
A kind of face of cylinder string props up the lower-chord panel point fastener of structure, comprise the strut connector, the sidewall of described strut connector is provided with two cable connecting lug and is connected otic placode with a pull bar, the head of described cable connecting lug is provided with the drag-line hole, and the head that described pull bar connects otic placode is provided with tie rod hole.Groove is beaten so that dock by force with strut etc. in the top of strut connector.
Effect:
(1), construction precision height.The utility model patent is owing to adopted face of cylinder string to prop up the lower-chord panel point fastener of structure, can be simpler, accurate and effective to carry out lower-chord panel point fastening, be not shifted, and can prevent the off-centre of drag-line, reduce the loss of stretching force, not can to drag-line exert an influence and also attractive in appearance, antiseptic effect is good.Therefore guaranteed drag-line, the prestressing force precision of vertical strut etc.
(2), construction cost is low.The face of cylinder 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 is low.
(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 angle between described two cable connecting lug is the right angle, and it is 135 to spend that described pull bar connects otic placode and angle between arbitrary cable connecting lug.
As preferably, described cable connecting lug and strut connector at right angles distribute, and described pull bar connects otic placode and is the shape distribution that is inclined upwardly with the strut connector.
As preferably, the angle of inclination that described pull bar connects otic placode is 40 degree～50 degree.
As preferably, described strut connector is a steel-casting.
Therefore, a kind of face of cylinder of the present utility model string props up the lower-chord panel point fastener of structure, and is rational in infrastructure, the construction precision height, and construction cost is low, and structure is safe in utilization.
