example 1

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

example 2

[0087] Such as Figure 18 As shown, the full-composite node connecting device is a double-ear hoop structure, which includes a composite material main rod 101 and a composite material auxiliary rod 102 that are connected, and a connecting structure is formed by the double-ear hoop structure 106 connecting the nodes. The locking block 104 realizes a fixed connection. The outer surface of the joint is regular and there is no exposed connecting piece; especially, no metal material connecting piece is exposed.

[0088] First put the two locking element assembly 104 into the binaural hoop structure 106 according to the directions P1 and P2 of the main sleeve D1 of the binaural hoop, and then place the composite material main rod 101 along the binaural hoop Insert with the main sleeve in the P3 direction until it reaches the position of the positioning table. Loosen the tension bolt 1043 of the locking piece assembly 104 to increase the distance between the two locking block assemblie...

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 node connecting device for components, in particular to a composite material node connecting device between composite material rods (tubes), and also provides an assembling method of the composite material node connecting device. Background technique [0002] Composite material components, due to their advantages such as high specific strength, light weight, corrosion resistance, and good electrical insulation performance, have been used in the fields of power transmission line towers and other load-bearing components, composite bridge components, and civil engineering. Especially in the comprehensive performance application of load-bearing / electrical insulation of transmission line poles, towers, etc., more and more attention has been paid by the industry. [0003] The existing connection modes of composite material component nodes mostly adopt traditional glue connection, open-hole bolt connection, glue connection / bolt hybrid conn...
