Background
At present, in the design and construction of a domestic reticulated shell structure, a node is mainly welded with a hollow ball node and a bolt ball node, the hollow ball node is mainly used for a single-layer reticulated shell, the node is processed according to rigid connection during design, the node is mainly used for a double-layer reticulated shell, and the node is processed according to hinge connection during design. In each actual project, there are various semi-rigid nodes. However, for the post-tensioning integrally-formed latticed shell structure introduced from australia, different requirements are provided for node rigidity in a forming stage and a bearing stage, the node rigidity in the forming stage is required to be as small as possible, the node rigidity in the bearing stage is required to be as large as possible, the existing common nodes are difficult to meet the requirements, and a special novel node is necessarily required to be invented.
Disclosure of Invention
In order to overcome the defects of the prior art, the utility model aims to provide a latticed shell rigid hinge conversion node which can meet the rigidity requirements of different stages, can ensure that the rigidity of the node is very small under the condition of ensuring the deformation in the forming stage, and realizes the one-way hinge function in the main bending direction; after the stretching is finished, the rigidity of the node can be greatly increased through simple processing, and the improvement of the bearing capacity of the structure is facilitated.
In order to achieve the above object, the utility model discloses a technical scheme be:
the latticed shell rigid hinge conversion node capable of adapting to rigidity requirements of different stages comprises:
the node ball part consists of a hollow ball 1, a node ball ear plate 5 arranged on the hollow ball 1 and node ball welding plates 2 symmetrically arranged at two sides of the node ball ear plate 5;
the device comprises a round steel tube 4, a conical head 3 positioned at one end of the round steel tube 4, two rod piece welding plates 8 symmetrically welded on the side surfaces of the conical head 3, and rod piece double-lug plates 7 symmetrically welded at the conical end position of the conical head 3;
and the number of the first and second groups,
and a bolt 6 connecting the rod lug plates 7 and the node lug plate 5, wherein the node lug plate 5 is located between the lug plates 7.
Wherein,
the node ball bonding plate 2 is parallel to the node ball lug plate 5.
The rod welding plate 8 is perpendicular to the node ball welding plate 2.
And a gap which does not influence the rotation of the rod piece and meets the welding condition is reserved between the node ball welding plate 2 and the rod piece welding plate 8.
The utility model discloses the node center is the clean shot, and the member adopts the circular steel tube, and the tip sets up the conical head, and double ear board and clean shot otic placode bolted connection through the conical head front end, the bending rigidity of the main crooked direction of member is very little among the stretch-draw process like this, has realized the one-way hinge function to reach and both can reduce member post-tension pulling force and take shape just stress, can prevent the purpose of anticipated external deformation again. Two welding small steel plates are respectively arranged on two sides of the conical head, after the tensioning process is finished and the reticulated shell is formed, the welding small steel plates perpendicular to the plane of the welding plate on the conical head are welded with the connecting plate, the node ball is connected with the rod piece through the welding plate, and the effect of increasing the node rigidity is achieved. The node can be flexibly arranged according to the difference of the number, the position and the properties of the rod pieces at the node, and the ear plates can be arranged to construct a one-way hinge and also can be directly welded with the rod pieces and the hollow spheres.

Fig. 1 is an external perspective view of the present invention.
Fig. 2 is a plan configuration view of the present invention.
Fig. 3 is an enlarged plan view of the one-way hinge portion of the present invention.
The specific implementation mode is as follows:
the technical solution of the present invention will be further explained in detail with the accompanying drawings.
As shown in fig. 1-3, the utility model mainly comprises three parts: a node ball portion, a bolt, and a rod portion. The node ball part comprises a hollow ball 1, two node ball welding plates 2 and a node ball lug plate 5, the node ball lug plate 5 and the node ball welding plates 2 are both welded on the hollow ball 1, the three plates are parallel, and the two node ball welding plates 2 are equidistant to the node ball lug plate 5. The member comprises conical head 3, circular steel tube 4, member double ear plate 7 and two member welding plates 8, and conical head 3 is located the top of circular steel tube 4, and 7 symmetric welds of member double ear plate are in 3 awl end positions of conical head, and 8 symmetric welds of two member welding plates are in 3 sides of conical head and are located same horizontal plane. The two parts are connected by bolts 6 through respective lug plates, and after the assembly, a rod welding plate 8 is perpendicular to the node ball welding plate 2 with a certain gap so as to be convenient to deform and can be welded together.
When tensioning is started, the rod part rotates along the axis of the bolt 6, and since the bolt 6 has little constraint effect on the rod part, there is substantially no rotational stiffness in the rotational direction. After the tensioning is finished and the rod part is in place, the end part of the rod welding plate 8 is welded and connected with the corresponding node ball welding plate 2, so that the rod part and the node ball part are reliably connected, and the effect of improving the rotational rigidity of the node is achieved.
