Abstract
The invention discloses a reticulated shell steel strand transforming node which comprises a node ball part, double rod piece ear plates and a bolt, wherein the node bar part is composed of a hollow ball, a node ball ear plate arranged on the hollow ball and node ball welding plates; the node ball welding plates are symmetrically arranged at two sides of the node ball ear plate; the double rod piece ear plates are composed of a circular steel tube, a tapered head at one end of the circular steel tube, and two rod piece welding plates which are symmetrically welded on side surfaces of the tapered head; the double rod piece ear plates are symmetrically welded at tapered end positions of the tapered head; the bolt is used for connecting the double rod piece ear plates with the node ball ear plate; and the node ball ear plate is arranged between the double ear plates. The reticulated shell steel strand transforming node ensures a low node rigid in the molding process under the condition that the deformation is ensured, and the one-way strand function is realized mainly in the bending direction; and after the tension, the node rigid can be greatly increased through simple processing, so that the improvement of the structure bearing capability is facilitated.
Description
Technical field
The invention belongs to civil engineering large-span space structure technical field, be mainly used in the latticed shell structure, particularly novel post tensioning monolithic molding net shell is specifically related to a kind of net shell and has just cut with scissors the conversion node for the demand of node stiffness variation.
Background technology
Adopt node to adopt welded hollow spherical joints and bolted spherical node in the design and construction of present domestic latticed shell structure, the former is multiplex in single-layer lattice shell more, and according to rigidly connecting processing, the latter is multiplex in Double-level Reticulated Shell during design, during design according to hinged processing.In each Practical Project, also has various structures with semi-rigid joints.But for the post tensioning monolithic molding latticed shell structure of introducing from Australia, shaping stage has different requirements from the carrying stage for node rigidity, shaping stage node rigidity should be as far as possible little, and carrying stage node rigidity should be tried one's best greatly, existing node commonly used is difficult to satisfy this requirement, certainly will need to invent a kind of special novel joint.
Summary of the invention
In order to overcome the shortcoming of above-mentioned prior art, the object of the present invention is to provide a kind of net shell just to cut with scissors the conversion node, can guarantee formative stage node rigidity in the situation that can guarantee that distortion is very little, realize unidirectional hinge function at main bending direction; Stretch-draw by simple process, can significantly increase node rigidity after finishing, and is conducive to the raising of structural-load-carrying capacity.
In order to achieve the above object, the technical solution used in the present invention is:
The net shell has just cut with scissors the conversion node, comprising:
By hollow ball 1, be arranged at the bolted node sphere otic placode 5 on the hollow ball 1, and the bolted node sphere part that is symmetricly set in bolted node sphere welded plate 2 compositions of bolted node sphere otic placode 5 both sides;
By round steel pipe 4, be positioned at the conehead 3 of round steel pipe 4 one ends, be symmetrically welded two rod member welded plates 8 in conehead 3 sides, and be symmetrically welded in the rod member ears plate 7 of conehead 3 cone end positions;
And,
The bolt 6 of connecting rod ears plate 7 and bolted node sphere otic placode 5, wherein bolted node sphere otic placode 5 is between ears plate 7.
Wherein,
Described bolted node sphere welded plate 2 is parallel with bolted node sphere otic placode 5.
Described rod member welded plate 8 is vertical with bolted node sphere welded plate 2.
Leaving between described bolted node sphere welded plate 2 and the rod member welded plate 8 does not affect the gap that rod member rotates and satisfies welding condition.
Node center of the present invention is hollow ball, rod member adopts round steel pipe, the end arranges conehead, ears plate by the conehead front end is connected with hollow ball otic placode bolt, the bending stiffness of the main bending direction of rod member is very little in the stretching process like this, realize unidirectional hinge function, both can reduce rod member posttension pulling force and shaping initial stress thereby reach, can prevent again the purpose of expecting outer distortion.Respectively there is the little steel plate of a block welding both sides on the conehead, when stretching process finishes, after the shaping of net shell, the little steel plate of welding vertical with the welded plate plane on the conehead is welded together with junction plate, bolted node sphere links together by welded plate and rod member, has reached the effect that increases node rigidity.This node can be according to the different of Nodes rod member number of locations and character and flexible arrangement both can arrange otic placode and construct unidirectional hinge, also can be directly with rod member and hollow ball welding.
Description of drawings
Fig. 1 is outward appearance axonometric drawing of the present invention.
Fig. 2 is planar configuration figure of the present invention.
Fig. 3 is the amplification planar configuration figure of the unidirectional hinge part of the present invention.
The specific embodiment:
Below by accompanying drawing technical scheme of the present invention is described in further detail.
As Figure 1-3, the present invention mainly is comprised of three parts: bolted node sphere part, bolt and rod member part.Wherein bolted node sphere part is comprised of hollow ball 1, two bolted node sphere welded plates 2 and bolted node sphere otic placode 5, and bolted node sphere otic placode 5 and bolted node sphere welded plate 2 all are welded on the hollow ball 1, and three plates are parallel and two bolted node sphere welded plates 2 are equidistant with bolted node sphere otic placode 5.Rod member is comprised of conehead 3, round steel pipe 4, rod member ears plate 7 and two rod member welded plates 8, conehead 3 is positioned at the top of round steel pipe 4, rod member ears plate 7 is symmetrically welded at conehead 3 cone end positions, and two rod member welded plates 8 are symmetrically welded at conehead 3 sides and are positioned on the same level.This two large divisions is coupled together by the otic placode of bolt 6 by separately, and the complete rear rod member welded plate 8 of assembly unit should be vertical with bolted node sphere welded plate 2 and a fixed gap is arranged, and with convenient distortion, and can weld together.
When stretch-draw began, the rod member part was rotated along the axis of bolt 6, because bolt 6 is very little for the effect of rod member partially restrained, does not substantially have rotational stiffness on rotation direction.When stretch-draw finishes, after rod member partly puts in place, end and the corresponding bolted node sphere welded plate 2 of rod member welded plate 8 is welded to connect, between rod member part and the bolted node sphere part there be reliable the connection like this, reached the effect of raising rigidity of rotation of joints.
