Technical Field
[0001] The utility model relates to the technical field of GFRP bar reinforcements, in particular to a GFRP bar reinforcement installation joint. Background Art
[0002] GFRP bar is a composite material made of polymer epoxy resin as matrix and glass fiber or carbon fiber as reinforcement through a composite process. It has the characteristics of lightness, corrosion resistance, aging resistance, good insulation, etc. It is widely used in different types of sports equipment, pipelines, shipbuilding, automobile and electronic product housings and printed circuit boards. In the use of GFRP bars, it is necessary to install them between the ends of two GFRP bars. Therefore, a GFRP bar installation joint is required.
[0003] A Chinese patent with publication number CN212802284U discloses a GFRP bar joint, comprising a non-metallic spindle-shaped joint body, an internal threaded hole screwed to the external thread of the GFRP bar is arranged along the axial direction of the joint body; the cross-section of the joint body is circular or regular polygonal; the joint body comprises a left joint body, a right joint body and a reinforcement body arranged between the left joint body and the right joint body; the outer diameters of the left joint body and the right joint body are equal, and the outer diameter of the reinforcement body is larger than the outer diameters of the left joint body and the right joint body; an annular steel wire mesh is arranged in the reinforcement body; the left joint body, the reinforcement body and the right joint body are integrally formed; the joint body is spindle-shaped as a whole, and the cross-section is hexagonal, which is convenient for fastening with tools, simple to make, easy to use, and easy to process, store and transport.
[0004] However, in this patent, the two GFRP bar ends are installed inside the joint body through an internal threaded hole axially arranged in the joint body and screwed with the external thread of the GFRP bar. Since the GFRP bar is generally long and there is no clamping device inside, the two GFRP bars that are only installed inside by threads may still shake, which makes the GFRP bar not installed very firmly inside, reducing its installation effect. In addition, in this patent, since it is an integral device, it cannot be separated into two parts as a whole. Since the two GFRP bar ends are installed inside it by threaded connection and the GFRP bar is generally long, it is difficult to disassemble it and the two GFRP bar ends, which increases the difficulty of disassembly.

A connecting long groove 17 is provided on one side of the supporting square rod 4, and a front inner wall and a rear inner wall of the connecting long groove 17 are provided with a limited long groove 18. Through the arrangement of the clamping component and the supporting component, the supporting component can support the clamping component, and when two GFRP bars are installed inside the device, the side surfaces of the ends of the two GFRP bars can be clamped by the device, so that the two GFRP bars installed inside the device can be firmly fixed, so that the device can avoid reducing the installation effect due to the shaking of the two GFRP bars installed inside the device, so that the device can improve the installation effect.
[0027] When in use, the arc-shaped pressing plate 12 is located inside the connecting long hole 13, the screw rod 21 is threadedly connected to the thread groove 24, the first mounting tube 7 and the second mounting tube 8 are in a mutually connected state and the first mounting tube 7 and the second mounting tube 8 form a complete mounting tube, and the GFRP bar is threadedly connected to the first mounting tube 7 and the second mounting tube 8 respectively. When two GFRP bars need to be installed inside the device, the device is moved, and when one end of the mounting tube formed by the first mounting tube 7 and the second mounting tube 8 corresponds to the end of a GFRP bar, the device is rotated so that the end of the GFRP bar enters the first mounting tube under the action of the threaded transmission. When the end of one GFRP bar enters the middle position of the installation tube formed by the first installation tube 7 and the second installation tube 8, the rotation of the device is stopped. At this time, one GFRP bar can be installed in the device, and the other GFRP bar is moved so that the end of the other GFRP bar corresponds to the other end of the installation tube formed by the first installation tube 7 and the second installation tube 8. The other GFRP bar is rotated so that the end of the other GFRP bar enters the installation tube formed by the first installation tube 7 and the second installation tube 8 under the action of thread transmission.
