The technical solution of the present invention is further explained by the following specific embodiments with reference to the attached drawings. It should be noted that the following specific examples are only illustrative, and the scope of the present invention is not limited thereto.
The utility model discloses on the basis of mortise type node, improve the optimization, obtain novel socket joint connection space lattice structure tooth line recess mortise type node. The original mortise-tenon joint adopts a common mortise-tenon joint structure, and the tooth-line groove mortise-tenon joint designs the groove and the tenon into a tooth-line form which is mutually occluded. Modeling analysis is carried out on the two types of nodes, and the bearing capacity and the stability of the tooth pattern groove mortise-tenon type steel node are far higher than those of a common mortise-tenon type steel node. The constitution of tooth line recess mortise-tenon joint formula node mainly includes: a novel hub ring body 1 with six tooth-shaped mortise slots; tenon 2 of H-shaped or round pipe beam; an H-shaped or circular tubular beam 3; a hexagonal spacer 4; a bolt 5; a small washer 6; a nut 7; a concave dovetail groove (mortise slot) 8 of the hub ring body 1; a tooth pattern lug 9 of an H-shaped or round pipe beam tenon; a thread groove 10 of the hub ring concave dovetail groove; a central cavity 11 in the hub ring body 1.
The novel socket joint connection space lattice structure tooth line groove mortise-tenon joint type node adopts a socket joint connection concept, and a mortise groove of a tenon insertion hub ring forms connection. The node hub ring body 1 adopts a tooth-shaped mortise groove (as shown in figure 5), the node beam can be a circular tube beam or an H-shaped beam (as shown in figure 8), the upper gasket and the lower gasket of the node adopt hexagonal gaskets (as shown in figure 7), and other parts of the node, including a bolt, a nut of the bolt and a small gasket, are determined according to the design requirement of the node if no special requirement exists.
For further understanding of the contents, features and functions of the present invention, the following examples are illustrated in detail with reference to the accompanying drawings:
the mortise-tenon joint type node with the tooth line grooves adopts a socket connection concept, and is shown in figure 1. And after the casting (the tooth-shaped tenon 2) is annularly welded with the circular tube or the H-shaped beam 3, the casting is inserted into the groove of the hub ring body 1 to form a node. The combination form of the tooth-shaped tenon 2 and the mortise can effectively prevent the horizontal displacement of the beam (as shown in figure 4), and the bearing capacity and the stability are far higher than those of a common groove. In order to prevent the tenon 2 from being vertically pulled out, after the tenon is inserted into the mortise, an upper hexagonal gasket 4, a lower hexagonal gasket 4 and a small washer 6 are arranged at two ends of the joint of the tenon 2 and the mortise, a bolt 5 penetrates through the center of the hexagonal gasket 4, and then two ends are connected by a nut 7 (shown in figures 2 and 3) so as to restrain the vertical displacement of the beam (shown in figure 3). In order to ensure the fault tolerance of the design, the mortise of the hub ring body 1 is slightly larger than the tenon 2 of the beam, and the installation requirements can refer to the specifications of the single-layer reticulated shell embedded hub node. Because the shape of the tooth-line groove mortise-tenon joint is special (as shown in fig. 6 and 8) and the size is small, the hub ring body 1, the tenon member 2, the bolt 5 and the nut 7 should be made of high-yield-strength steel, such as steel Q345, and the beam 3 and the hexagonal gasket 4 of the joint can be made of common steel.
The control parameters to be considered in the design of the tooth pattern groove mortise-tenon joint type node comprise: the thickness of the wall of the hub ring body, the outer diameter of the hub ring body, the heights of the hub ring body and the tenon, the tenon shape, the maximum and minimum widths of the tenon, the depth of the mortise dovetail, the number of the mortise dovetails of the hub ring body, the form and the number of the tenon and the mortise dovetail thread and the adopted materials.
The above-mentioned embodiments, further detailed description of the objects, technical solutions and advantages of the present invention, it should be understood that the above-mentioned embodiments are only specific embodiments of the present invention, and are not intended to limit the present invention, and any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present invention should be included in the scope of the present invention.
