As an important infrastructure supporting communication equipment, signal towers are widely distributed in urban and rural areas. To ensure communication quality, signal towers typically need to be equipped with a large number of antennas and other communication equipment, which are fixed to the signal towers using various connectors.

[0029] Traditional signal tower connection nodes mostly use metal materials (such as steel), which have high strength but have problems such as heavy weight and easy corrosion; while non-metallic materials such as plastics or glass fiber reinforced plastics (GFRP) have the advantages of being lightweight and corrosion resistant, but they are still insufficient in terms of mechanical properties.

[0030] In recent years, composite materials have gradually attracted attention due to their lightweight, high strength, good weather resistance and easy processing properties. Therefore, developing a new type of composite material connection node is crucial for optimizing signal tower structure.

[0031] Therefore, the design concept of this application is to design a node multi-pass structure that can adapt to the mechanical properties of composite materials, so as to make node multi-passes using lightweight, high-strength, good weather resistance and easy-to-process composite materials, and improve the various problems existing in the signal tower connection nodes of the above-mentioned metal materials, plastics or glass fiber reinforced plastic (GFRP) and other non-metallic materials.

[0032] like Figure 1-5 As shown, this application provides a composite material connection node multi-pass for signal towers, used for truss-type tower node connection, including several sub-lobes, each sub-lobe including an integrally formed circular tube lobe 1 and a square tube lobe 2, the circular tube lobe 1 of all sub-lobes are bonded together in sequence to form a circular tube 3, and every two sub-lobes of square tube lobe 2 are bonded together to form a square tube 4.

[0033] The circular tube 3 is provided with at least one square tube 4; the circular tube 3 is connected to the tower uprights of the tower, and the square tube 4 is connected to the tower body.

[0034] The sub-lobes are made of epoxy resin and unidirectional glass fiber fabric; the fiber laying direction of the sub-lobes is the axial direction of the multi-channel nodes; the outer walls of the round tube 3 and the outer walls of the square tube 4 are respectively circumferentially laid-up with unidirectional glass fiber fabric.

[0035] The material used in this application is glass fiber reinforced composite material, which has the advantages of low dielectric and low insertion loss, greatly reducing the impact on signal transmission.

[0036] The applicant, considering the anisotropy of the mechanical properties of composite materials, needs to design the fiber orientation; and considering the molding difficulty, requires segmented molding, such as... Figure 2-5 The segmentation method shown uses vacuum-assisted injection molding, with epoxy resin and unidirectional glass fiber fabric as raw materials, and the fiber is laid along the multi-channel axis (longitudinal direction) of the node.

[0037] After being segmented and molded, they are bonded together using structural adhesive, such as Figure 1 As shown, a certain thickness of unidirectional glass fiber fabric is then hand-laid into the circumferential direction of the round and square tubes to increase the circumferential strength of the nodes.

[0038] Based on the mechanical properties of composite materials, this solution designs the multi-connector nodes as a modular assembly structure, making it possible to manufacture multi-connector nodes using composite materials, thus better improving various problems existing in current signal tower connection nodes.
