Description

Technical Field

[0001] The invention relates to the technical field of node structure assembly, and in particular to a node structure for large-size lines and an assemblable installation method. Background Art

[0002] The traditional angle bracket connection method has various specifications for special-shaped structures with various angles, which requires high process precision. The small stiffness of the angle bracket causes the weakening of the node strength. The connection between the aluminum profile rod and the angle bracket opening requires precise on-site adjustment, which increases the complexity and process of construction and installation. Therefore, generally, the angle bracket or node plate connection is suitable for simple truss structures and is low in cost.

[0003] However, when using angle brackets or node plates for connection, if the joint gap is too large, it may affect the accuracy and stability of the structure. The stiffness of the angle bracket is greatly reduced compared to the rod, resulting in weakened node strength. Although the connection nodes of cast aluminum alloy profiles can achieve more complex geometric shapes and high connection strength requirements, the mold cost of aluminum castings is relatively high. Extruded aluminum profiles with rectangular tubes or other shaped sections can be manufactured into sections of different shapes as needed. The joint gap at the corner of the aluminum frame is too large, and the installation error is large.

[0004] In summary, it is necessary to propose a large-size line node structure and an assemblable installation method to solve the above problems. Summary of the invention

[0005] The object of the present invention is to provide a large-size line node structure and an assemblable installation method to solve the problems raised in the above background technology.

[0006] To achieve the above object, the present invention provides the following technical solutions:

[0007] A large-size line node structure, comprising:

[0008] Three aluminum square tubes B;

[0009] Six aluminum square tubes A, which are respectively arranged on both sides of the aluminum square tube B;

[0010] Six aluminum square tubes C, two of which are arranged on both sides of one of the aluminum square tubes B, and the other four are arranged between every two aluminum square tubes A that need to be connected, to form an aluminum alloy support frame.

[0011] Preferably, the two aluminum square tubes B and aluminum square tubes A on the same side are arranged in a square frame shape, and every two aluminum square tubes B and aluminum square tubes A are arranged opposite to each other, and the upper and lower ends of the aluminum square tube A on the same side of the square frame are connected to another inclined aluminum square tube A through an aluminum square tube C and a connecting piece A, and the ends of the two inclined aluminum square tubes A on the same side are installed on another aluminum square tube C through the aluminum square tube C and the connecting piece A and are fixed by the aluminum square tube B to form a large-size line node frame.

[0012] Preferably, the angle between the two inclined aluminum square tubes A is 60°, wherein the aluminum square tube A located above forms an angle of 30° with the horizontal plane, and wherein the aluminum square tube A located below forms an angle of 330° with the horizontal plane.

[0013] Preferably, two connecting column mounts are installed at the upper and lower ends of the other side of the square frame, each connecting column mount is provided with an adapter B inside, and the adapter B and the connecting column mount are installed and fixed by bolt group A and bolt group B.

[0014] Based on the above-mentioned large-size line node structure, the present invention also proposes an assembly installation method for a large-size line node structure, according to any one of the claims, comprising the following steps:

[0015] S1. Aluminum square tube frame construction:

[0016] First, six aluminum square tubes A are respectively arranged on both sides of three aluminum square tubes B to form a basic frame structure, so that every two aluminum square tubes B and aluminum square tubes A are arranged opposite to each other to form a square frame;

[0017] Aluminum square tubes C are used as connectors, two of which are arranged on both sides of one of the aluminum square tubes B, and the other four are arranged between every two aluminum square tubes A that need to be connected, so as to strengthen the stability of the frame and form a complete aluminum alloy support frame;

[0018] Connect the aluminum square tube A and the connector A by nailing to ensure a firm connection and accurate position;

[0019] S2. Frame connection and tilt setting:

[0020] Connect two inclined aluminum square tubes A on the same side to another aluminum square tube C through an aluminum square tube C and a connector A, and make the angle between the two aluminum square tubes A be 60°. Specifically, the aluminum square tube A located on the upper side should be at an angle of 30° to the horizontal plane, while the aluminum square tube A located on the lower side should be at an angle of 330° to the horizontal plane.

[0021] Through this tilted setting, a part of the node framework of large-size lines with a specific angle is formed;

[0022] S3.Frame fixing and bracket installation:

[0023] Install two column mounts at the upper and lower ends of the other side of the square frame. These mounts will be used to connect with adapter B.

[0024] Place adapter B into the column mount and use bolt group A to initially fix it, so that the connection between adapter B and the column mount is tight and stable;

[0025] Fine-tune the frame by adjusting bolt group A and bolt group B to make it accurate and stable. This step is crucial to the accuracy and stability of the entire large-size line node frame.

[0026] S4. Final inspection and adjustment:

[0028] Preferably, the connector A is a closed-cavity profile connector with a fisheye hole, the bolt group A is a hanging bolt and a left and right limit bolt group, and the bolt group B is an upper and lower limit bolt.

[0029] Compared with the prior art, the beneficial effects of the present invention are as follows: the present invention adopts closed-cavity profiles with fisheye holes as connecting nodes, and only needs to be fixed by nailing on the outside of the aluminum profile rod. The aluminum profile rods are connected into one by the closed-cavity profile, which ensures the integrity of the main force-bearing node position, greatly enhances the node connection strength, and is beneficial to improving the assembly accuracy and overall performance of the aluminum frame. Direct multi-angle profile mold opening can achieve multi-angle precise connection of aluminum alloy frames, simplify the connection process, and improve installation efficiency.

[0045] Example 2

[0046] Based on the above large-size line node structure, in practical applications, an assembly method for large-size line node structure can be used, specifically, including the following steps:

[0047] S1. Aluminum square tube frame construction:
