Description

Technical Field

[0001] The present disclosure relates to the field of nodes of space structures, and in particular to a reinforced space structure node. Background Art

[0002] Aluminum is the metal element with the largest reserves on earth, accounting for 8% of the reserves of the earth's crust. It is a metal material with great development prospects. Aluminum alloy is made by adding copper, magnesium, manganese, silicon and other alloy elements to pure aluminum. Aluminum alloy can be classified according to processing process, heat treatment method or chemical composition. This classification method makes aluminum alloys in different groups have similar mechanical and process properties. At present, the internationally accepted aluminum alloy grade expression method is based on the alloy system of the material, which is mainly divided into 7 major alloy series. The 6XXX series of aluminum alloys are widely used in building structures. Since the 1940s, aluminum alloys have been widely used in building structures at home and abroad. At present, more than 6,000 aluminum alloy space structures have been built in the world. As early as 1954, the United Kingdom built an aluminum alloy spherical lattice shell structure with a span of 111.3m. At present, the diameter of the largest span aluminum lattice shell in the world has reached 144m. There are also many famous aluminum alloy space structures in China. The more representative ones are the Memorial Hall of the Battle of Pingjin built in 1996 and the greenhouse of Shanghai Chenshan Botanical Garden built in 2011.

[0003] There are many node systems in the space grid structure, among which the most widely used ones include Germany's Mero system, the United States' Unistrut system, Canada's Triodetic system, Japan's NS system, the United States' Temcor system, the welding ball system, and so on. For the space aluminum alloy lattice shell structure, due to the poor weldability of the aluminum alloy itself, its main node types include hub nodes, Tymco nodes, and bolt ball nodes. In addition, some domestic experts and scholars have conducted a series of studies on cast aluminum nodes, but due to the poor ductility of cast aluminum nodes, it is still difficult to promote their application. At present, Tymco nodes are the most widely used in engineering. The upper and lower flanges of the connected rods are connected to the disc cover plate through 8 stainless steel high-strength bolts. Most nodes are connected to 6 H-shaped aluminum alloy rods to form a space structure.

[0004] However, the Tymco node still has some shortcomings. Since the Tymco node has 6 rods at the same node, when the disc size is small, the bolt holes connecting the 6 rods will weaken the tensile strength of the disc cover. In addition, since there is no direct connection between the webs of the aluminum alloy rods, the shear force is only transmitted through the disc cover, the shear strength is weak, and there is stress concentration near the bolt holes. Therefore, during use, the damage often starts from the place with the greatest stress, resulting in the phenomenon of "strong components, weak nodes". This phenomenon violates the requirement of "strong nodes, weak components" in engineering structure design, so the existing disc cover nodes need to be improved and optimized.

[0043] Before describing the solution to the problem, it is helpful to define some specific terms.

[0044] The “node” described in this article is an aluminum alloy space node that is reinforced by T-plate connection.

[0045] In order to make the objectives, technical solutions and advantages of the present disclosure more clearly understood, the present disclosure is further described in detail below in combination with specific embodiments and with reference to the accompanying drawings.

[0046] Certain embodiments of the present disclosure will be described more fully below with reference to the accompanying drawings, some but not all of which are shown. In fact, the various embodiments of the present disclosure may be implemented in many different forms and should not be construed as limited to the embodiments set forth herein; rather, these embodiments are provided so that the present disclosure satisfies applicable legal requirements.

[0047] In a first exemplary embodiment of the present disclosure, a reinforced space structure node is provided. Figures 1 to 5 As shown, the reinforced spatial structure node disclosed in the present invention includes: four H-shaped rods 3, a disc cover plate 1 and two T-shaped connectors 4; each H-shaped rod 3 includes two flange plates 31 and a web plate 32, and the web plate 32 connects the two flange plates 31; the disc cover plate 1 is connected to the flange plates 31 of each H-shaped rod 3; each T-shaped connector 4 includes a first connecting plane 41 and a second connecting plane 42, and the two ends of the first connecting plane 41 are respectively a first connecting end 411 and a second connecting end 412; one end of the second connecting plane 42 is connected to the first connecting plane 41, and the other end of the second connecting plane 42 is a third connecting end 421; the first connecting end 411, the second connecting end 412 and the third connecting end 421 are respectively connected to the web plate 32 of the H-shaped rod 3 by bolts 2, and the bolts 2 are high-strength bolts. It should also be noted here that the specifications and quantity of the bolts 2 should be determined according to the magnitude of the node force. Similarly, the radius and thickness of the disc cover 1 also need to be determined according to the magnitude of the node force. This is design common sense that technical personnel in this field should be able to understand and will not be repeated here.

[0048] Furthermore, the first connection planes 41 of the two T-shaped connectors 4 are opposite to each other, respectively clamping the webs 32 of the two H-shaped rods 3. The webs 32 of the other two H-shaped rods 3 are respectively fixed to the third connection ends 421 of the two T-shaped connectors 4. The webs 32 of the two H-shaped rods 3 can be placed on both sides of the third connection end 421, such as Figure 2 , 3 As shown, it can also be placed on the same side of the third connection end 421, such as Figure 4 shown.

[0049] The present invention adopts the method of on-site assembly. After each unit is adjusted in place, a pneumatic rivet gun is used to tighten the high-strength bolts 2 to fix the H-shaped rod 3 to the disc cover 1, and the H-shaped rod 3 to the T-shaped connector 4. At the construction site, materials should be stored separately, and there should be certain isolation measures for materials of different materials. The surfaces of the disc cover 1, H-shaped rod 3 and T-shaped connector 4 should be kept clean, and cracks, peeling and bubbles are not allowed.

[0050] The following is a detailed description of each component of the enhanced spatial structure node of this embodiment.

[0051] The H-shaped rod 3 is made of aluminum and may have a specification of 250*125*9*5. The bolts are distributed along a straight line on the H-shaped rod 3 and may be distributed in a single row and / or multiple rows without specific limitation.

[0052] Disc cover 1, Figure 6 Schematic diagram of the structure of the disk cover plate of the reinforced spatial structure node of the embodiment of the present disclosure. Figure 6 As shown, the bolts 2 are radially distributed along the disc cover 1; the radius of the disc cover 1 needs to meet the requirement that the H-shaped rods 3 do not interfere with each other; the arching amount of the disc cover 1 depends on the angle between the corresponding H-shaped rod 3 and the node tangent plane.

[0053] T-type connector 4, Figure 7 Schematic diagram of the structure of the T-shaped connector of the reinforced spatial structure node of the embodiment of the present disclosure. Figure 7 As shown, the thickness of the T-shaped connector 4 should meet the requirement that the T-shaped connector is not damaged before the H-shaped rod 3. The bolts are distributed along a straight line on the T-shaped connector 4, specifically in a single row and / or multiple rows without specific limitation.
