AI Technical Summary

Problems solved by technology

However, problems arose with the use of metal pipes
The high density of metal pipes makes them heavy to transport and difficult to handle during installation and dismantling
The high heat capacity of the metal tube means that it can be very uncomfortable when operating at high or low temperatures
In addition, in certain environments, sometimes even after a short period of service, metal pipes are subject to high rates of corrosion, rendering them useless for their purpose

Embodiment Construction

[0154] figure 1 A cross-sectional view of the structural tube 1 is shown. The tube is a hollow cylinder of circular cross-section with an outer diameter D of 48.30 mm and a wall thickness of 4.00 mm.

[0155] Tube 1 contains the best as figure 2 Multiple layers shown. A polymeric resin 3 is used as a matrix to bind the reinforcing fibers 2 together, thereby providing a monolithic composite for a cylindrical tube of overall wall thickness T. Polymer resin 3 is polyester. In an alternative embodiment, vinyl esters may be used.

[0156] In the illustrated embodiment, T is 4.00 mm, but in other embodiments (not shown), a different thickness T is used to provide specific load carrying requirements for the scaffolding system.

[0157] In the illustrated embodiment, the reinforcing fibers are glass fibers, such as aluminoborosilicate glass containing 1% by weight alkali metal oxide. In other embodiments (not shown), the fiber reinforcement may be formed from glass, aramid, bor...

Abstract

There is provided a structural tube (1) comprising a fibre reinforced polymer wherein the tube comprises a plurality of layers (21, 22, 23, 24, 25) of reinforcing fibres with the fibres of at least one layer having a different orientation to those of another layer. Also provided is a kit of structural tubes and a structural tube assembly.

Description

technical field [0001] The present invention relates to structural tubes, particularly but not limited to scaffold tubes, and structures and structural tube groups comprising structural tubes. Background technique [0002] Structural pipes are known for many applications, one of the more traditional applications being as scaffolding pipes. Tubes such as those used in said tube and fit scaffold systems are widely used in the construction and restoration of buildings and other infrastructure. Currently, tubes and mating scaffolding systems employ metal tubes. The design and installation of metal tube scaffolding systems benefit from decades of experience in successful use. However, problems arose with the use of metal pipes. The high density of metal pipes makes them heavy to transport and difficult to handle during installation and dismantling. The high heat capacity of metal pipes means that they can be very uncomfortable to operate at high or low temperatures. Furtherm...
