Problems solved by technology

However, in practical engineering applications, steel columns have poor lateral bending resistance, weak corrosion resistance, and short service life.
At the same time, the steel column is heavy, and it is quite difficult to transport, install and maintain in mountainous areas

Embodiment

[0035] a kind of like figure 1 The passive flexible protection column shown, it is flange 1, column body 2 and base 3 in order from top to bottom, and described flange, column body and base are all made of fiber-reinforced composite material; The fiber-reinforced composite The material is composed of at least one matrix material and at least one fiber reinforcement; the matrix material is selected from one or more of epoxy resin, phenolic resin, and polyurethane; the fiber reinforcement is continuous fiber yarn and / or Or fiber cloth, the fiber reinforcing material is selected from one or more of basalt fiber, glass fiber, aramid fiber, and carbon fiber.

[0036] The mass percentage of the matrix material in the fiber reinforced composite material is 25%-35%. It not only meets the requirement of material strength but also saves resin.

[0037] The fiber-reinforced composite material is also added with one or more of antioxidants and light stabilizers.

[0038] The antioxidan...

Abstract

The invention discloses a passive flexible protection stand column which is sequentially provided with a flange, a column body and a base from top to bottom. The flange, the column body and the base are all made of a fiber reinforced composite material; the fiber reinforced composite material is formed by compounding at least one basis material and at least one fiber reinforced material; the basis material is selected from one or more of epoxy resin, phenolic resin and polyurethane; and the fiber reinforced composite material is continuous filament yarn and / or fiber cloth and is selected from one or more of basalt fibers, glass fibers, aramid fibers and carbon fibers. The passive flexible protection stand column has the beneficial effects of being high in intensity, high in anti-bending capacity, resistant to corrosion, long in service life, light in component, rapid in installation and the like; and the stand column solves the problems of dry and wet subsidiary stress and temperature subsidiary stress of a traditional steel column / concrete pedestal system.

Description

technical field [0001] The invention relates to a passive flexible protection system, in particular to a passive flexible protection column. Background technique [0002] my country is a mountainous country. Due to crustal movement, rainstorm erosion, rock weathering, human production activities and other reasons, landslides, collapses and other disasters may occur on both soil and stone slopes. The characteristics of its disasters are widespread, accidental, and long-term, which seriously affect human production activities and the safety of life and property. [0003] Passive flexible protection system is an effective way to deal with the above-mentioned disasters, and it can adapt to various complex slope environments. In the high-resistance passive flexible protection system, the column is the most critical supporting component. Once bent, the entire system will lose its protection ability. [0004] At present, the most widely used passive flexible protection system is ...
