Description

Self-riveting type node of aluminum alloy space grid structure

Technical Field

The utility model relates to a spatial structure aluminum alloy node, concretely relates to aluminum alloy space grid structure is from riveting formula node belongs to the civil engineering field.

Background

The aluminum alloy has the characteristics of light dead weight, corrosion resistance and easiness in processing, so that the aluminum alloy is more and more widely applied to space grid structures. The uk "exploration" dome built in 1951 was the first aluminium alloy space reticulated shell structure in the world, since which aluminium alloys began to be used on a large scale in the field of construction engineering. Since the last 90 s, aluminum alloy structures began to enter our country. Up to now, more than 10 large-scale aluminum alloy spatial structures including the Tianjin Shujin battle memorial, Shanghai International gymnastics center and Shanghai Pudong natatorium have been built.

Because the aluminum alloy has the characteristics of poor weldability and obviously reduced strength after welding, mechanical connection is mainly adopted in the space grid structure. At present, the node forms which are widely applied mainly comprise plate type nodes, bolt ball nodes, cast aluminum nodes and embedded nodes. The node forms or structures are complex, construction is difficult, construction progress is slowed down, or mechanical properties of the nodes are damaged due to welding. Therefore, the design of the aluminum alloy node form which is simple in structure, convenient to construct and free of welding is of great significance.

SUMMERY OF THE UTILITY MODEL

The utility model aims at overcoming not enough among the prior art, provide a simple structure, construction convenient, highly prefabricated, avoid welded aluminum alloy space grid structure from riveting formula node.

The utility model aims at realizing through the following technical scheme:

the utility model provides an aluminum alloy space grid structure is from riveting formula node, includes the node core, the node core is cross structure, the upper and lower both ends of node core all are equipped with cross apron, the tip of apron and node core all is equipped with the tenon structure, apron and node core are connected with H type aluminium, be equipped with on the H type aluminium with tenon structure matched with tongue-and-groove structure.

Furthermore, the cover plate and the node core are connected by structural adhesive.

Compared with the prior art, the utility model discloses a beneficial effect that technical scheme brought is:

the aluminum alloy node has the characteristics of small density and light weight, and can effectively reduce the self weight of the structure relative to a steel node, so that the aluminum alloy node is more suitable for a large-span space grid structure. In a building structure, an aluminum alloy structure mainly adopts two modes of welding and mechanical connection, but the weldability of an aluminum alloy material is poor, and the welding can reduce the performance of the aluminum alloy material, so that the aluminum alloy structure is prevented from being welded as much as possible. The utility model discloses connect through traditional tenon fourth of the twelve earthly branches structure from riveting formula node, be a mechanical connection mode, the effectual adverse effect of avoiding welded connection. The four branches of the node are highly symmetrical, so that the node is ensured to have no obvious weak direction. The node appearance is the cross form, and furthest has kept the original shape of two crossing members in nodical department, and upper and lower apron is the flange board of H shaped steel simultaneously, compares in traditional board-like node, has saved the material of extra apron, and the economic nature is more excellent, and the molding is more graceful. The utility model discloses can realize high batch production prefabrication, need not to carry out processing to the node again in the site operation process, consequently can greatly improve the efficiency of construction, improve the site operation environment, fully respond to the call of national green, high-efficient construction.
