Specific embodiment
To make the objectives, technical solutions, and advantages of the present invention clearer, below in conjunction with specific embodiment, and reference
Attached drawing, the present invention is described in further detail.
The present invention is right including node Ultimate Tensile, pressure and curved bearing capacity in order to improve the local stability of hub type node
The rod piece plug of spatial mesh structure Tenon type hub type node (NDHJ) and the mechanical interlocking of node hub body groove improve and optimize.
Because this node is by the mechanical interlocking power transmission among node rod piece plug and hub body fourth of the twelve Earthly Branches slot, the present invention is to pass through
Optimize the hub type node of mortise and tenon type to the improvement of node connection.The office that can improve node is improved and optimized to node
Portion's stability can also improve the stability of the entire spatial mesh structure with hub type node.
The present invention is to solve the used technical solution of well-known technique to be: the tension of hub type node,
Pressure and it is curved be by the mechanical interlocking power transmission between the rod piece plug of node and the groove of hub body, but the ordinary plug of hub type node
Section is weaker than component itself, will lead to node unstability under load action.
By studying the local stability of common hub type node, including limit bending resistance, drawing and pressure bearing capacity, destruction mode hair
Mainly there are two modes for the destruction of this existing node, and first mode is failure mode between hub body slot, and second mode is rod piece
It is broken in the smallest width.The reason is that between the stress of load action lower node is concentrated mainly on hub body slot most with rod piece plug
At small width.Therefore, the present invention is based on the analyses to hub type destruction of a node mode, to solve the stress in load action lower node
Concentration problem establishes the new Tenon type hub type node of spatial mesh structure.In the new Tenon type hub type section of spatial mesh structure
In point, there are the rod piece plug of tooth line and hub body groove that the typical circular plug of original hub type node rod piece and circular recessed is substituted
Slot.The rod piece maximum stress of common hub type node exists only in one section of section of plug, and the novel rod piece plug for having tooth line
Three sections of sections of stress distribution to entire plug can be improved the bearing capacity of rod piece plug, and improve the stabilization of node in this way
Property.Similarly, the maximum stress on common hub type node hub body exists only on one between groove section of section, and novel hub body
The bearing capacity of rod piece plug can also be improved, and improve node stress distribution to entire groove surface in this way by having the groove of tooth line
Stability.In conclusion section can be improved with the new Tenon type hub type design of node method of the spatial mesh structure in the present invention
The bearing capacity of point, reaches the better local stability of node, and naturally improves the space lattice knot for entirely using hub type node
The stability and safety of structure.

The assembling of the new Tenon type hub type node of spatial mesh structure mainly includes the hub body 1 of six hub body grooves 4 of band, such as
Fig. 7, shown in 8；H-type or tubular type rod piece 2, as shown in Fig. 1,4 or as shown in Fig. 2,5,9；The plug for having tooth line of H-type rod piece 2
3, as shown in Figure 11,12；Hub body groove 4, as shown in Fig. 1,2,7,8；Big gasket 5, as shown in Fig. 1,2,4,6；Bolt 6 is such as schemed
1, shown in 2,4,5；Nut 7, as shown in Fig. 1,2,4,5；Small washer 8, as shown in Fig. 1,2,4,5；The centre bore 9 of bolt hub body 1,
As shown in figs 6-8；Rod piece larynx 10, as shown in Fig. 2,5,9；The tooth line 13 of hub body groove, as shown in Figure 7,8；The plug tooth of plug 3
Line 12, as shown in Figure 11,12.
In order to further appreciate that invention, features and effects of the invention, following instance is hereby enumerated, and cooperate attached drawing detailed
Carefully it is described as follows:
The Tenon type hub type node of spatial mesh structure uses the continuous concept of socket joint, as shown in Figs. 1-5.Space lattice
Structure Tenon type hub type node leans on the mechanical interlocking power transmission of the plug 3 of rod piece 2 and the hub body groove 4 of node, so design can mention
The plug 3 of the rod piece 2 of high node bearing capacity and the hub body groove 4 of node are the key that in design of node.The present invention is in order to improve
The bearing capacity of node proposes the design of the rod piece plug 3 and hub body groove 4 of tooth line according to three principles.One, it keeps inserting
First 3 minimum widith is constant, such as the L width in Figure 11, then in order to which the stress for being distributed 3 face of plug is designed in the two sides of plug 3
Symmetrical tooth line is based on the principle, the more balance of plug 3 and the more stress distributions of tooth line of hub body groove 4 as shown in figure 11.
Two, according to the spiral principle of design bolt, for the tooth line of plug 3 and hub body 1 closer to 1 outer diameter of hub body, the stress of tooth line is bigger.Institute
With, design tooth line when to outer tooth thread width it is bigger than the width to center tooth line, as shown in Figure 11 and Fig. 7.Three, closer to
1 outer diameter of hub body, the distance between hub body groove 4 is bigger, so to the depth of 1 outer diameter tooth line of hub body than to hub body when design tooth line
The depth of 1 center tooth line is big, such as L1, L2 and L3 in Figure 11.According to research and analysis as a result, space networks proposed by the present invention
The bearing capacity and stability of the new Tenon type hub type node of lattice structure are more preferable than common hub type node.
After the Tenon type hub type node of spatial mesh structure is by casting (plug) and round tube or H-type rod piece boxing, node
Hub body 1 can connect together with rod piece 2.The plug 3 of each rod piece 2 of node can one by one insertion node hub body it is recessed
Slot 4, the combining form of this plug 3 and hub body groove 4 can prevent the horizontal displacement (as depicted in figs. 1 and 2) of beam.In order to prevent
Rod piece 2 is extracted, and after plug 3 is inserted into hub body groove 4, bolt 6 passes through the combining form both ends for being placed on plug 3 and hub body groove 4
5 center of gasket big up and down and 8 center of small washer, then with bolt 6, nut by both ends connect (as shown in Fig. 1,2,4 and Fig. 5),
With the vertical displacement of constraining member 2.In order to ensure the fault-tolerance of design, hub body groove 4 is a little bigger than the plug 3 of rod piece 2,
His installation requirement and specification can refer to the specification of the embedded hub node of single-layer lattice shell.
The design control parameter to be considered of the new Tenon type hub type node of spatial mesh structure includes: the external diameter of hub, hub
The tooth line depth of the tooth line quantity of the height of body and plug, plug and hub body, the tooth line width of plug and hub body, plug and hub body
The form of the tooth line of degree, the minimum and maximum width of plug, plug and hub body.The new Tenon type hub type of other spatial mesh structures
The design and machined parameters of node can refer to the specification of the embedded hub node of single-layer lattice shell.
Particular embodiments described above has carried out further in detail the purpose of the present invention, technical scheme and beneficial effects
Describe in detail bright, it should be understood that the above is only a specific embodiment of the present invention, is not intended to restrict the invention, it is all
Within the spirit and principles in the present invention, any modification, equivalent substitution, improvement and etc. done should be included in protection of the invention
Within the scope of.
