Abstract
A reticulated casing rigid-hinge transformation node capable of adapting to rigidity requirements at different stages comprises a hollow sphere, a node sphere lug plate arranged on the hollow sphere, a node sphere portion consisting of node sphere welding plates symmetrically arranged on two sides of the node sphere lug plate, a round steel tube, a conical head located at one end of the round steel tube, two rod piece welding plates symmetrically welded on the side of the conical head, rod piece double-lug plates symmetrically welded at the conical end position of the conical head, and bolts for connecting the rod piece double-lug plates and the node sphere lug plate. The node sphere lug plate is located between the rod piece double-lug plates. The reticulated casing rigid-hinge transformation node can ensure the rigidity of the node at a forming stage to be very small under the condition that deformation can be guaranteed, and achieves a one-way hinging function in the main bending direction. After stretching and drawing are finished, the node rigidity can be improved remarkably through simple treatment, and improvement of structural bearing capacity is facilitated.
Description
Technical field
The utility model belongs to civil engineering large-span space structure technical field, be mainly used in latticed shell structure, particularly novel post tensioning monolithic molding net shell for the demand of node stiffness variation, is specifically related to a kind of net shell that adapts to the different phase rigidity requirement and has just cut with scissors the conversion node.
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 during design, according to rigidly connecting processing, the latter is multiplex in Double-level Reticulated Shell, 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 purpose of this utility model is to provide a kind of net shell that adapts to the different phase rigidity requirement 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 adopted in the utility model is:
The net shell that can adapt to the different phase rigidity requirement has just cut with scissors the conversion node, comprising:
By hollow ball 1, be arranged at the bolted node sphere otic placode 5 on hollow ball 1, and be symmetricly set in the bolted node sphere part that the bolted node sphere welded plate 2 of bolted node sphere otic placode 5 both sides forms;
By round steel pipe 4, be positioned at the conehead 3 of round steel pipe 4 one ends, be symmetrically welded in two rod member welded plates 8 of 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 rod member welded plate 8 does not affect the gap that rod member rotates and satisfies welding condition.
The utility model node center 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, in stretching process, the bending stiffness of the main bending direction of rod member is very little 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.On conehead, respectively there is a little steel plate of block welding both sides, when stretching process finishes, after the net shell is shaped, the little steel plate of welding vertical with the welded plate plane on 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 difference 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 utility model.
Fig. 2 is planar configuration figure of the present utility model.
Fig. 3 is the amplification planar configuration figure of the unidirectional hinge part of the utility model.
The specific embodiment:
Below by accompanying drawing, the technical solution of the utility model is described in further detail.
As Figure 1-3, the utility model 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 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 same level.Otic placode by separately couples together this two large divisions by bolt 6, 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, substantially there is no 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 bolted node sphere part, there be reliable the connection like this, reached the effect of raising rigidity of rotation of joints.
