example 1

[0085] like Figure 11 As shown, the assembly process is schematically shown. First, put the locking element assembly 104 into the single-ear hoop structure 103 according to the axial direction P1 of the hoop main sleeve, and then insert the composite material auxiliary rod 102 along the axial direction P2 of the hoop auxiliary rod sleeve, Until it reaches the position of the positioning platform, loosen the tension bolt 1043 of the locking piece assembly 104, increase the distance between the middle seams of the locking block assembly by 5 mm to 8 mm, and approach the arc surface of the composite material main rod 101, along the Insert the composite material main rod 101 to the positioning platform in the P3 direction, and pull the locking blocks 1041 and 1042 by tightening the nuts 1044 to expand and compress the composite material main rod 101 and the composite material auxiliary rod 102 to realize the integral connection.

example 2

[0087] like Figure 18 As shown, the all-composite material node connection device is a double-ear hoop structure, which includes a connected composite material main rod 101 and a composite material auxiliary rod 102. The locking block 104 realizes the fixed connection. The outer surface of the joint is regular and there are no exposed joints; especially no exposed metal joints.

[0088] Firstly, put the 2 pieces of locking piece assembly 104 into the double-eared hoop structure 106 according to the P1 and P2 directions of the main sleeve D1 of the double-eared hoop, and then put the composite material main rod 101 along the double-eared hoop Insert it into the P3 direction of the main sleeve until it reaches the position of the positioning platform, loosen the tension bolt 1043 of the locking piece assembly 104, and increase the distance between the two locking block assemblies 1041 and 1042 by 5mm to 8mm. Close to the mating surface M1-1 of the composite material main rod ...

Abstract

The invention discloses a connection device for composite nodes and an assembly method for the connection device. The connection device is connected between a composite main rod and each of one or more composite auxiliary rods crossed with the composite main rod. The connection device is characterized in that the connection device is of a hoop structure; the hoop structure is formed in a way that a main sleeve with the inner diameter matched with the outer diameter of a connection section of the composite main rod is crossed with one or more auxiliary rod sleeves with the inner diameters matched with the outer diameters of the connection sections of the composite auxiliary rods and is integrated with the one or more auxiliary rod sleeves through a vacuum auxiliary preformation process; a self-locking mechanism is also mounted in an inner cavity formed at the composite part of the main sleeve and the auxiliary rod sleeves; the connection device is convenient to assemble and novel in structure, and an exposed metal connecting piece is inexistent on the outer surface of the joint; the connection belongs to a non-damage connection; the connection device can be used for connecting one main rod with two composite auxiliary rods, is simple to maintain, safe to operate and suitable for a larger load bearing occasion, has an anti-thunder effect and can meet the connection requirements in the absence of the metal connecting piece and a large bearing load at the same time.

Description

technical field [0001] The invention relates to a component node connection device, in particular to a composite material node connection device between composite material rods (pipes), and also provides an assembly method for the composite material node connection device. Background technique [0002] Composite components, because of their high specific strength, light weight, corrosion resistance, and good electrical insulation properties, have been used in load-bearing components such as transmission line poles and towers for power facilities, composite bridge components, and civil engineering. Especially in the comprehensive performance application of bearing / electrical insulation of transmission line poles and towers, it has been paid more and more attention by the industry. [0003] Existing joints of composite material components mostly adopt traditional glue joints, open-hole bolt connections, glue joint / bolt hybrid joints or transfer connections through metal parts....
