Problems solved by technology

[0003] Welded hollow ball joints and intersecting joints have good integrity, but due to the large amount of welding work required, and most of them are high-altitude operations, the welding quality cannot be guaranteed, and the construction speed is slow. Recently, with the rise of labor costs, the cost of such joints is increasing The bolt ball joints are assembled joints, and the joints and rods are generally produced in batches in the factory, and the on-site assembly does not require welding, which is convenient for assembly and disassembly
However, in the application, it is generally treated as a hinge node, and cannot be applied to a single-layer spatial grid structure

Embodiment 1

[0036] Figure 1 to Figure 6 It is a schematic diagram of nodes in Embodiment 1 of the present invention, and the nodes of the present invention include:

[0037] Central node 1, connecting arm 3, sleeve 4, rod 5, high-strength bolt 6. The central node 1 is connected by the central ring 2 and several connecting arms 3 at a certain angle, and there are four bolt holes on the connecting arms 3; the number of connecting arms 3 is determined by the specific spatial structure; the sleeve 4 is processed by steel pipe cutting, The sleeve 4 also has four bolt holes for connection; the sleeve 4 is sleeved on the connecting arm 3, and the length of the sleeve 4 is greater than the length of the connecting arm 3; the rod 5 is a square steel pipe or a rectangular steel pipe, and the sleeve 4 On the sleeve 4; after the node assembly of the present invention is completed, the length of the sleeve 4 extending into the rod 5 will be greater than the length of the connecting arm of the centra...

Embodiment 2

[0046] Such as Figure 9 to Figure 11It is a schematic diagram of Embodiment 2 of the present invention. When the structural span is large and the section of the rod 5 is increased, the length of the high-strength bolt 6 will be lengthened, and the size of the central node 1 will also be increased a lot, which will inevitably cause unnecessary waste. In order to adapt to the connection of large-section rods, the second embodiment is improved as follows: in the first embodiment, the high-strength bolt 6 is long, and in the second embodiment, the high-strength bolt 6 is divided into two upper and lower bolts, such as Figure 9 As shown, the upper bolt fixes the upper flange of the rod 5 and the sleeve 4 and the upper part of the connecting arm 3, and the lower bolt fixes the lower flange of the rod 5 and the sleeve 4 and the lower part of the connecting arm 3; in the embodiment In one, the connecting arm 3 is solid, in the second embodiment, as Figure 10 As shown, the connect...

Abstract

The invention discloses a novel assembled joint applicable to a monolayer triangular space grid structure. The novel assembled joint is mainly composed of five parts, namely a center joint, connecting sleeves, high-strength bolts, upper and lower cover plates and a center bolt. The center joint is composed of a center circular ring and six connecting arms in connection. The connecting sleeves are machined from steel tubes. Bolt holes are arranged in corresponding positions of the center joint, the sleeves and road pieces. During assembly, one end of each sleeve is sleeved with one connecting arm while the other end of the same is sleeved with one rectangular steel tube, the sleeves, the connecting arms and the rectangular steel tubes are connected through the high-strength bolts, bending moment and axial force of the rod pieces are transmitted through the bolts and friction and mechanical squeezing among the steel tubes, the sleeves, the connecting arms and the center ring, and the triangular space grid structure joint is formed by all the connections. The assembled joint is wide in application range, convenient for industrialized batch production, good in assembling capacity, convenient to construct, high in construction and assembly quality, capable of meeting the requirement of the monolayer space grid structure on joint bearing capacity and rigidity and broad in application prospect.

Description

technical field [0001] The invention relates to a large-span space structure, in particular to a prefabricated node of a single-layer triangular space network structure. Background technique [0002] The single-layer spatial grid structure is favored by architects and structural engineers for its advantages of reasonable force, beautiful appearance, and transparent structure, and is widely used. Figure 8 Shown is a schematic diagram of a spherical shell, a commonly used single-layer space grid structure, in which 6 rods gather at one point to form a node, and 3 rods form a triangular grid. The two important components of a single-layer space grid structure are rods and nodes. Whether the structure can bear normal force, the form of nodes and their strength and stiffness are the key factors, and the damage of nodes often leads to the failure of several rods connected to it. failure. In "Research Progress and Practice of Spatial Structure Joint Design", Fan Zhong evaluated t...
