Technical field
The utility model belongs to the field of engineering technology of construction work prestressed cable structures, and relating in particular to a kind of is the node apparatus of main member with butterfly shape steel-casting, is specially adapted to stretching rope structures such as rope dome, rope net roof system.
Background technology
In many stretching rope structures, exist two above cable wires to intersect at the situation of a bit.Common node processing method is to adopt multiple hinged joint, promptly the adjustable rope head of all cable wires all rotates round junction point, the problem that this node apparatus exists is: in the work progress, when applying prestressing force, adjusting cable wire tightness, angle between cable wire and cable wire can change more sensitively, thereby the phenomenon that " power to shape less than " or " shape to power less than " can occur, the installation effect of difficult control " power to shape to ".
The utility model content
The stretching rope structure node device that it is main member that the purpose of this utility model provides a kind of butterfly shape steel-casting makes the angle automatic forming between cable wire and cable wire, is easy to realize the good construction effect of " power arrives to shape " in the Cable Structure installation process.
In order to achieve the above object, the utility model comprises the angle automatic forming system that butterfly shape steel-casting, annular girder steel, cable wire, adjustable rope head, steel pin axle and fixed-hinged support are formed.
Wherein, butterfly shape steel-casting has a bigger circular hole, is used to install annular girder steel, and makes that this steel-casting can be around the rotational of annular girder steel, and the flexible cable structure in the middle of making and the rigidity ring beam at edge form the stretching rope structure automatically.Also have a plurality of pin shaft holes on this steel-casting in addition, be used for the rope head of erection support and many cable wires, make the rope axis not rotate, but behind stretch-draw forming, can intersect at the center of circle of this circular hole automatically around the center of circle of circular hole.
Further, butterfly shape steel-casting connects cable wire and annular girder steel, and behind the stretch-draw forming, the radial load of generation is born by annular girder steel, then also passes to fixed-hinged support by the pin shaft hole of butterfly shape steel-casting perpendicular to the load on annular girder steel plane.
Further, the rope head that cable wire links to each other with butterfly shape steel-casting is the adjustable rope head of adjustable length, and the reading of hydraulic system when tightening adjustable rope head can be calculated the internal force of cable wire.
Preferably, the internal force that fixed-hinged support does not bear tensioning cable and produced, bearing only bear the load of the composite member that butterfly shape steel-casting and cable wire, annular girder steel be formed by connecting.
Preferably, locking nut is positioned at butterfly shape steel-casting circular hole inboard, and after the stretching rope adjusting put in place, it can be used to lock annular girder steel and butterfly shape steel-casting.
The utility model makes it compared with prior art owing to adopted above-mentioned technical scheme, has following advantage and good effect:
The utility model device passes through to adopt butterfly shape steel-casting to connect, and the angle energy automatic forming between cable wire and cable wire is easy to realize the effect of Cable Structure installation process " power arrives to shape ".The power transmission circuit is clear and definite, and installation is methodically arranged, and is easy to operate, can shorten the construction period effectively, control the installation quality.
