Abstract

The invention provides a composite pultrusion sectional material with an A-shaped section, and belongs to the field of profile structures. The problem that an existing connecting sectional material islow in bearing capacity is solved. The sectional material is of an integrated structure and comprises a left arm, a right arm and a cross arm, the upper end of the left arm and the upper end of the right arm are connected to form an included angle, the left arm and the right arm are connected through the cross arm, and the left arm, the right arm and the cross arm are connected to form an A-shaped section. The sectional material is made of a composite material which is composed of reinforcing fibers and a base material, and the sectional material is formed by pultrusion along the vertical direction of the A-shaped section. The composite pultrusion sectional material is mainly used for main girder structures of a communication pole tower, an electric pole tower or other composite materialsin polygonal pole tower forms.

Description

technical field [0001] The invention belongs to the field of profile structures, in particular to an A-shaped cross-section composite material pultruded profile. Background technique [0002] Composite material connection technology is one of the difficulties that plague the application of composite materials. Applying composite materials to pole-tower structures can solve problems such as poor weather resistance, poor designability, and reduced self-weight. The main girders of the existing composite pole-tower structures mostly adopt rectangular, circular, I-shaped cross-sections, etc., and the connections between the main girders and between the main girders and the struts are all made of metal connectors and adapters. Increased the self-weight and maintenance costs of the tower. Contents of the invention [0003] In order to solve the problems in the prior art, the present invention proposes an A-shaped cross-section composite material pultrusion profile. [0004] In...
