Detailed Description

In order to clearly understand the above objects, features and advantages of the present invention, the present invention will be further described with reference to the accompanying drawings and embodiments. It should be noted that the embodiments and features of the embodiments of the present application may be combined with each other without conflict.

Examples

An assembled truss joint, as shown in fig. 1-6, comprises a first connecting piece 1, a second connecting piece 2 and a sleeve. The first connecting piece 1 is fixed at one end of one rod piece, the second connecting piece 2 is fixed at one end of the other rod piece, and the two rod pieces are connected through the first connecting piece, the second connecting piece and the sleeve. The rod 4 is, without limitation, a tubular shape, such as various types of steel pipes, and the rod 4 has a certain wall thickness. In some embodiments, the first connector 1 is welded to one end of the rod member, and the second connector 2 is welded to the other end of the rod member, so that the first connector 1 is connected with the second connector 2, and the rod member are matched.

As shown in fig. 1, the first connecting member 1 includes a flange plate 11, a plurality of bolt holes are formed in the periphery of the flange plate 11, one surface of the flange plate 11 is welded to one end surface of the rod, and a V-shaped plate 12 is formed in the other surface of the flange plate 11.

As shown in fig. 2, the second connector 2 includes a flange plate 21, a plurality of bolt holes are formed in the periphery of the flange plate 21, one surface of the flange plate 21 is welded to one end surface of the rod, and a connecting plate 22 is formed on the other surface of the flange plate 21. In the connection matching, the connecting plate 22 and the V-shaped plate 12 are connected to form a triangle, and the specific implementation form may be that both sides of the V-shaped plate 12 abut against one side of the connecting plate 22 (fig. 4), or both ends of the connecting plate 22 abut against the inner sides of both wings of the V-shaped plate (fig. 5). Preferably, in the connection mode shown in fig. 5, the connection plate 22 forms a leaning force on the inner sides of the two wings of the V-shaped plate, and the outer sleeve forms a leaning force on the outer sides of the two wings of the V-shaped plate, so that the connection stability is better.

The sleeve comprises two sleeve elements 3, as shown in fig. 3, the two sleeve elements 3 being axially separable or combinable into a complete sleeve. The sleeve elements 3 are assembled to form flanges at both ends, which are capable of engaging the

flange plates

11 and 21. The outer wall of the sleeve element 3 is bolted. The inner wall of the sleeve element 3 is provided with a plurality of layers of rib plates which are distributed along the axial direction of the sleeve, each layer of rib plate is composed of two

small rib plates

31 and 32, and in connection fit, the two

small rib plates

31 and 32 are respectively butted with one wing of the V-shaped plate 12 and the outer side of the connecting plate 22.
