Problems solved by technology

[0003] The object of the present invention is to provide a steel-continuous fiber composite bar for construction, the fiber composite bar is composed of threaded steel core, fiber cloth and basalt fiber bundles, has a reasonable structure, and the fiber used as a reinforcing material Both cloth and basalt fiber bundles are fully impregnated with resin, which can effectively meet the design strength of reinforced concrete structures. At the same time, it can also overcome the defects of strong material brittleness and high price in existing fiber reinforced composite materials (FRP), and is suitable for widespread use.

Embodiment 1

[0026] In an embodiment, the preparation method of fiber composite bars specifically includes the following steps:

[0027] (1) Processing: The purchased HRB400 rebar is processed into a rebar inner core. The basic properties of HRB400 rebar are shown in Table 1:

[0028] Table 1

[0029] Rebar type model Yield strength (MPa) Elastic modulus (Gpa) Weight (kg / m) diameter (mm) Rebar HRB400 420 200 0.617 10

[0030] First, use a grinder to remove the symmetrical longitudinal long ribs on both sides of the threaded steel bar, and then use alcohol to scrub clean before proceeding to the following steps.

[0031] (2) Decontamination: Use sandpaper to remove the embroidered stains on the outer surface of the inner core of the threaded steel bar, and then use gauze dipped in acetone to clean the inner core of the threaded steel bar;

[0032] (3) Fiber cloth coating resin: Atlac430 epoxy bisphenol A vinyl resin is selected as the coating resin, and i...

Embodiment 2

[0043] The difference between this embodiment and embodiment 1 is that the selected fiber cloth types are different. In this implementation, the preparation method of fiber composite bars specifically includes the following steps:

[0044](1) Processing: Process the purchased HRB400 threaded steel bar into the inner core of the threaded steel bar. First, use a grinder to remove the symmetrical longitudinal ribs on both sides of the threaded steel bar. Then, use alcohol to clean it, and then proceed to the following steps .

[0045] (2) Decontamination: Use sandpaper to remove the embroidered stains on the outer surface of the inner core of the threaded steel bar, and then use gauze dipped in acetone to clean the inner core of the threaded steel bar;

[0046] (3) Fiber cloth brushing resin: choose Atlac430 epoxy bisphenol A vinyl resin as the brushing resin, cut 30 bundles of basalt fiber cloth made of CBF13-2400Tex basalt fiber, and lay it flat, one end of which is glued Temp...

Abstract

The invention discloses a steel-continuous-fiber composite bar for a building. The fiber composite bar is formed by compounding a threaded reinforcing steel bar inner core, fiber cloth and a basalt fiber bundle and has a reasonable structure. The fiber cloth and the basalt fiber bundle used as reinforcing materials are fully immersed by using resin and can effectively satisfy the design strength of a reinforced concrete structure. Meanwhile, the steel-continuous-fiber composite bar further can overcome the deficiencies of strong brittleness, high price and the like of existing fiber reinforced plastic (FRP) and is suitable for wide popularization and use.

Description

technical field [0001] The invention relates to a steel-continuous fiber composite bar for construction, in particular to a composite bar reinforcing material used in a reinforced concrete structure, and belongs to the field of composite materials. Background technique [0002] Reinforced concrete structure (RC structure) is a structure built with steel bars and concrete. The steel bars bear tension and the concrete bears pressure. It has the advantages of firmness, durability, good fire resistance, saving steel and lower cost than steel structures. One of the more common construction forms in the construction industry, it is mostly used in various super high buildings and long-span structures, such as bridges, tunnels and other load structures. In its structure, as the basic reinforcing material, steel bar has strong comprehensive performance, but it has disadvantages such as easy corrosion. Based on this situation, in recent years, fiber reinforced composites (FRP) have be...
