Abstract
The utility model relates to a carbon fiber bar connecting device, which comprises eudipleural two tubular connecting components, wherein the end parts of two sections of carbon fiber bars respectively penetrate through respective connecting components and are fixedly connected between the two connecting components, and the outer rings of the two connecting components are both provided with external screw threads and are connected by a threaded tube; a reserved adhesive filling hole which is communicated with a cavity between the two connecting components is arranged on the wall body of the middle of the threaded tube, and the end parts of the two sections of carbon fiber bars respectively penetrate through the respective connecting components, then are connected in a crossing way and bent and then penetrate back into the respective connecting components; and the roots of elbows of the carbon fiber bars at the inner sides of the connecting components are wound and fixed by carbon fiber wires. The carbon fiber bar connecting device has a simple structure and a strong applicability, saves materials, obviously reduces cost, and can be widely used in reinforced treatment works of carbon fiber bars.
Description
Technical field
The utility model relates to a kind of carbon fibre bar linkage.
Background technology
Carbon fibre bar than traditional reinforcing bar, has many superiority as a kind of advanced composite material (ACM), and carbon fibre bar intensity height, corrosion resistance and good, anti-fatigue performance are good, non magnetic, and damping performance is better.Therefore, in concrete structure, replace reinforcing bar, can effectively overcome the problems such as low-intensity, corrosion of reinforcing bar, improve the performance of structure with carbon fibre bar.But the connection between the multistage carbon fibre bar all lack always a kind of simple in structure, be convenient to operate connected mode, present connected mode is than waste material, cost is higher relatively.
The utility model content
The utility model purpose is to provide a kind of carbon fibre bar linkage, and simple in structure, applicability is strong, and economical with materials significantly reduces cost.
To achieve these goals, the utility model adopts following technical scheme: the carbon fibre bar linkage, comprise symmetrical two tubular connecting elementss, the end of two sections carbon fibre bars is passed separately connecting elements and fixedly connected between two connecting elementss respectively, and two connecting elements outer rings are equipped with external screw thread and connect by the screwed pipe that is provided with.
Described screwed pipe middle part wall body be provided with two connecting elementss between the reservation glue filling opening that is communicated with of cavity.
The end of described two sections carbon fibre bars penetrates connecting elements separately respectively, wears back after interconnection and the bending then in the connecting elements separately, and the carbon fibre bar elbow root of connecting elements inboard is fastened with carbon fiber wire.
The internal orifice of described connecting elements the inner is provided with breach along the place.
The utility model is mainly used in carbon fibre bar and connects, and improves the applicability of carbon fibre bar in engineering is used.This device mainly is made up of members such as structure glue, carbon fibre bar, carbon fiber wire, connecting elements, screwed pipes.Its principal character is that carbon fibre bar is passed connecting elements, end reflexed, and twine in the bending place, end with carbon fiber wire, and in the screwed pipe injecting structure glue, realize that carbon fibre bar connects.This technology construction is simple, and applicability is strong, and economical with materials significantly reduces cost, can be widely used in carbon fibre bar consolidation process engineering.

The specific embodiment
Embodiment: shown in Fig. 1-4, the carbon fibre bar linkage, comprise symmetrical two tubular connecting elementss 3, the end of two sections carbon fibre bars 1 is passed separately connecting elements 3 and fixedly connected between two connecting elementss 3 respectively, and two connecting elements 3 outer rings are equipped with external screw thread and connect by the screwed pipe 4 that is provided with.In the present embodiment, the end of two sections carbon fibre bars 1 penetrates connecting elements 3 separately respectively, wears back after interconnection 5 and the bending then in the connecting elements 3 separately, and carbon fibre bar elbow 6 roots of connecting elements 3 inboards are fastened with carbon fiber wire 7.Screwed pipe 4 middle part wall bodies be provided with two connecting elementss 3 between the reservation glue filling opening 2 that is communicated with of cavity.
The connecting elements internal request is coarse, is convenient to bond with structure glue; There is small gap part, connecting elements end, is convenient to the bundle place's anchoring of carbon fiber wire group; Screw thread is arranged at top, connecting elements overstriking position, and two joints are reverse thread and arrange; The carbon fibre bar end bends, and is connected with the joint bending; Become an integral body; Rotation outer counter silk screwed pipe, jointing is whole; In the middle of the screwed pipe aperture is arranged, be used for injecting structure glue; The utility model both can be directly used in and connect two carbon fibre bar joints; Also can be earlier with injecting structure glue in the end coupling, after waiting to reach intensity, the utilization screwed pipe connects, and applies prestressing force tension joint, injecting structure glue in screwed pipe more at last, thus carbon fibre bar is applied prestressing force.
General carbon fibre bar joint construction key step: 1, connecting elements is passed carbon fibre bar respectively, screwed pipe also passes a carbon fibre bar joint; 2, with carbon fibre bar bending, two joint interconnections; 3, the carbon fibre bar after will bending penetrates connecting elements, and twines with carbon fiber wire in folded end, and group's knot firmly; 4, the rotation screwed pipe connects two joints; 5, pour into structure glue from screwed pipe middle part aperture, enrich connecting elements.
Can apply pre-stressed carbon fiber muscle joint construction key step: 1, connecting elements is passed carbon fibre bar respectively, screwed pipe also passes a carbon fibre bar joint; 2, with carbon fibre bar bending, two joint interconnections; 3, the carbon fibre bar after will bending penetrates connecting elements, and twines with carbon fiber wire in folded end, and group's knot firmly; 4,, and treat that it reaches design strength with injecting structure glue in the connecting elements; 5, the rotation screwed pipe applies prestressing force, and two joints are connected tension; 6, pour into structure glue from screwed pipe middle part aperture, enrich connecting elements.
