Embodiment Construction

[0029] The present invention is further described below in conjunction with accompanying drawing.

[0030] Figure 1 and Figure 2 are the plate-planted body-node aluminum alloy space truss structures composed according to the rule of "three non-coplanar chain rods fix the space and one new node", and all the node bodies and all the rods are made of aluminum alloy made. Its span can be large or small, and it is often used in large-span factory buildings, exhibition halls, gymnasiums, bridge projects and tower projects.

[0031] It can be seen from Figure 4 that each rod end of all the rods of the space truss has an opening for the implantation of the limb plate of the node body. The node body (1) is provided with a limb board U(5) in the X(2) direction of the truss, a limb board V(6) in the Y(3) direction, and a limb board W in the Z(4) direction (7), a total of three limbs. The U(5) direction limb plate on the node body is implanted in the X(2) direction on the truss to meet...

Abstract

The invention discloses a plate implanted body node aluminum alloy space truss structure, which comprises all space truss body-like nodes (1), and aluminum alloy chord members (2) and aluminum alloy web members (3) and (4) gathered at each node and connected with the nodes in a space truss. The plate implanted body node aluminum alloy space truss structure is characterized in that: two ends of all aluminum alloy members of the space truss are provided with openings for implanting limb plates of the nodes, each body-like node is provided with U-shaped, V-shaped and W-shaped limb plates in the X, Y and Z directions of the space truss respectively, and the three limb plates are implanted into the ports of all the members gathered at the nodes in the corresponding X, Y and Z directions and fastened with the members by using bolts or rivets to form the plate implanted body node aluminum alloy space truss structure system with the advantages of geometrical invariance, reasonable stress, reliable structure and convenience for design, manufacture and construction.

Description

1. Technical field [0001] The invention relates to a space truss, which is a space structure system commonly used in the field of building construction, bridge construction and tower structure engineering. 2. Background technology [0002] Plane trusses can only bear loads acting within the plane of the trusses, but in practice, the loads on the structure often act on several planes in different directions. Therefore, in engineering, there is also a type of truss with obvious spatial characteristics, which can bear loads in several planes acting in different directions. This system is called space truss. The simplest rule to form a geometrically invariant spatial truss is to start from a planar triangle or from the foundation, and fix a new node with three non-coplanar links in sequence. By adding new nodes sequentially according to this rule, a geometrically invariant space truss can be formed, and a space truss that conforms to this composition rule and has no redundant l...
