Connection construction member capable of regulating tightness and manufacturing and assembling method thereof

Abstract

The invention discloses a connection construction member capable of regulating tightness for a transmission tower and a manufacturing and assembling method thereof. The connection construction member is assembled by a connecting rod, two connecting plates and two U-shaped connecting plates, wherein the connecting rod is made of glass fiber reinforced plastic composite material, and two ends of the connecting rod are provided with male threads. The manufacturing and assembling method for the connection construction member capable of regulating the tightness comprises the following steps of: 1) carrying out pultrusion on the connecting rod, and lathing a positive-buckling male thread and a reverse-buckling male thread on two ends of the connecting rod; 2) carrying out pultrusion on a pin, and lathing the male thread on two ends of the pin; 3) carrying out pultrusion on two pairs of nuts; 4) forming the connecting plates and the U-shaped connecting plates in a vacuum flow guide technology; 5) processing pin holes in the center positions where the connecting plates are opposite to the U-shaped connecting plates; and 6) fixedly connecting the connecting rod, the two connecting plates and the two U-shaped connecting plates into a connection construction member by the pin holes, the pin and the nuts. The manufacturing and assembling method is simple and easy to operate, has the characteristics of light weight, corrosion resistance and electric insulation, is adjustable, is safe to assemble, does not need to maintain and repair because the weather resistance lasts for 20 years, and is favorable for popularizing and applying.

Description

technical field [0001] The invention relates to an elastically adjustable connecting member made of composite material and a method for making and assembling the same. Background technique [0002] In recent years, composite material transmission towers have gradually been recognized by the market and widely used due to their excellent characteristics such as light weight, high tensile strength and corrosion resistance; The connecting members such as the traditional metal or stainless steel still use the connecting members, and their structures are mostly U-shaped or runway-shaped; because the materials used for the composite transmission tower and the metal or stainless steel connecting members belong to two different materials, the steel The difference in degree and corrosion resistance is very large. At the same time, the U-shaped or runway-shaped connecting member has a single structure and only two connection points at both ends; when in use, the connecting member made ...

[0002] In recent years, composite material transmission towers have gradually been recognized by the market and widely used due to their excellent characteristics such as light weight, high tensile strength and corrosion resistance; The connecting members such as the traditional metal or stainless steel still use the connecting members, and their structures are mostly U-shaped or runway-shaped; because the materials used for the composite transmission tower and the metal or stainless steel connecting members belong to two different materials, the steel The difference in degree and corrosion resistance is very large. At the same time, the U-shaped or runway-shaped connecting member has a single structure and only two connection points at both ends; when in use, the connecting member made of metal or stainless steel will be corroded due to climate change and environmental factors. The U-shaped or runway-shaped connecting member is easily deformed after being corroded, which will cause loosening between the connecting member and the fixed composite material cross arm or transmission pole, resulting in leakage or power failure, causing serious safety hazards to the transmission line, and also Limit the popularization and application of composite transmission towers
