The node forms are complex, the processing and manufacturing difficulty is high, and the process is complex. The plate type nodes which are commonly used in the node form can cause material waste to a certain extent due to the requirement that the section heights of the aluminum profile components are the same, and are not suitable for structures with particularly complex space angles. Therefore, in order to meet the connection of the space intersection rod pieces, an aluminum alloy node form which is clear in force transmission and convenient and fast to construct is designed, and the problem to be solved urgently in engineering is solved.

Detailed Description
Preferred embodiments of the present invention are described below with reference to the accompanying drawings. It should be understood by those skilled in the art that these embodiments are only for explaining the technical principle of the present invention, and are not intended to limit the scope of the present invention. It should be noted that in the description of the present invention, the terms of direction or positional relationship indicated by the terms "front", "rear", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", etc. are based on the directions or positional relationships shown in the drawings, which are for convenience of description only, and do not indicate or imply that the device or element must have a specific orientation, be constructed and operated in a specific orientation, and thus, should not be construed as limiting the present invention.
Example 1:
an X-shaped core-insert node is used for connecting rod pieces 2 in a space reticulated shell. As shown in fig. 1-2, the whole of the rod member 2 is a square tube, the end of the square tube is a connecting portion, and a plurality of connecting holes are uniformly distributed along the circumferential direction of the connecting portion for connecting the rod members 2.
The X-shaped core-insert type node 1 is provided with four core-insert parts 11 for inserting rod connecting parts and an X-shaped cross connecting part 12, and the four core-insert parts 11 and the cross connecting part 12 are integrally connected in an X shape. Wherein, the included angle between two adjacent inserting core parts 11 is determined according to the design requirement of the space reticulated shell. The X-shaped insert core type node 1 is an aluminum piece and is formed by integral casting. To reduce weight, there are communicating hollow cavities within the ferrule portion 11 and the cross-connect portion 12.
In this embodiment, the cross-sectional shape of the ferrule portion 11 is a square tube, the ferrule portion 11 is inserted into the square tube-shaped connection portion of the rod 2, the ferrule portion 11 is provided with a threaded hole corresponding to the connection hole of the rod connection portion, and the rod 2 and the X-shaped ferrule type node 1 are fixedly connected by screwing in the stainless steel bolt 3. In this way, the four rods 2 are connected together. It should be noted that the cross-sectional shape of the ferrule portion 11 may also be a solid rectangle (such as a plate), and the solid ferrule portion 11 can improve the connection strength but also increase the weight. When the connecting portion of the rod 2 is a circular tube, the cross-sectional shape of the insertion core portion 11 may be circular or circular tube.
In order to increase the connection strength and the appearance, the cross-sectional area of the ferrule 11 is smaller than that of the cross-connecting part 12, and after the insertion, the connection part of the rod 2 and the cross-connecting part 12 have a continuous connection shape.
Therefore, the X-shaped insert core type node 1 has the advantages of being attractive in appearance, light in weight, easy to manufacture and easy to realize connection among the rod pieces 2 relative to a plate type node, a bolt ball node, a cast aluminum node and a hub type node, and particularly enables the four rod pieces 2 to be crossed and gathered at one point, two opposite rod pieces to be collinear, and the force transmission direction among the rod pieces 2 is not inclined.
Example 2:
unlike embodiment 1, as shown in fig. 3 to 4, the rod member 2 is a circular tube, and the connecting portion of the rod member 2 is provided with a radial threaded hole. The core part 11 of the X-shaped core-insert type node 1 is hollow, and the cross section of the core part is in a circular tube shape. The inserting core part 11 is inserted outside the rod connecting part, and the inserting core part 11 is provided with a connecting hole corresponding to the threaded hole of the tubular rod 2. When in connection, the core inserting part 11 is sleeved outside the rod connecting part, and the rod 2 and the X-shaped core inserting type node 1 are connected and fixed through the stainless steel bolt 3.
Obviously, the same effects as those of embodiment 1 can be obtained in this embodiment.
The present invention is not described in detail in the prior art.
