Embodiment Construction

[0023] The present invention will be further described below in conjunction with the embodiments shown in the accompanying drawings.

[0024] The present invention proposes an inclusive joint, which includes a curved plate for connecting the main chord and the web of the pipe structure truss, the main chord part and the web part connected with the curved plate, and the main chord part And the web part is the part of the tube structure truss that is close to the curved plate and belongs to the contained node. image 3 Shown is the structural diagram of the contained joint, where 1 is the curved plate, 2 is the main chord part, and 3 is the web part; Figure 4 is the front view of the curved slab in the contained joint; Figure 4a , Figure 4b , Figure 4c and Figure 4d respectively Figure 4 Cross-sections of the curved plate at A-A, B-B, C-C, and D-D.

[0025] The above-mentioned curved plate 1 includes an edge portion and a protrusion protruding from the edge portion i...

Abstract

The invention provides a containing-type node, belonging to the technical field of mechanical connection parts. The containing-type node comprises a bent plate for connecting a main chord of a tube structure truss and a main chord part, wherein the bent plate comprises an edge part and a bulge part which protrudes in a bunch shape from the middle of the edge part; the outline of the edge part is matched with that of the main chord; and the edge part is wrapped on the main chord part. The containing-type node can effectively simplify the node structure, lowers the stress concentration, and enhances the strength and reliability, so that the truss structure which is usually lighter than the box-type structure by more than 30% can be widely adopted and is especially applied to the fields of hoisting and engineering machinery and heavy-duty mobile load.

Description

technical field [0001] The invention belongs to the technical field of mechanical connectors, and relates to a node, especially an inclusive node. Background technique [0002] In the field of lifting and transportation machinery and large construction machinery, under the same conditions, the truss-type metal structure is more than 30% lighter than the box-type structure (the weight of the longitudinal and transverse ribs inside the box-type structure is about 1 / 3 of its total weight). When the tubular trusses are under compression, they have equal strength and are most suitable for trusses. In addition, the truss structure also has many advantages such as no internal reinforcement, simple manufacturing process, and small wind load in outdoor environments. However, in the prior art, the truss structure has not been widely used, and the main limiting factor is that the design and manufacture of its nodes (that is, the intersection of the main chord and the web) are difficul...
