Example Embodiment

[0013] The following is a description with examples in conjunction with the drawings:

[0014] First, use 80-160 mesh sandpaper to properly sand the surface of the clamping part of the pultruded fiber-reinforced resin rod 4; the anchor clamp 2 is made of aluminum alloy, and at 0.5-0.8MPa air pressure, 60-140 The target sand particles have been sandblasted; put the anchor clamp 2 outside the pultruded fiber reinforced resin rod 4, put it into the anchor cup 1, and hit the thicker end of the anchor clamp 2 with a heavy object to clamp the pultruded Fiber-reinforced resin rod 4; put the above-mentioned connected structure into the pre-opened groove at the bottom of the glulam beam, use instant glue to glue the anchor cup and the position where the wooden beam notches tightly, and use the bolt 3 to fix the anchor cup 1 to On wooden beams.

Abstract

The invention discloses a practical and simple anchor device for an end part of a pultruded fiber reinforced resin rod. The anchor device can ensure that the pultruded fiber reinforced resin rod fully plays a role in reinforcing, can prevent shear failure of an adhesive layer, and simultaneously can provide the acting force in a vertical direction to prevent the pultruded fiber reinforced resin rod from getting in or out of a notch due to overlarge rigidity when a beam is bent, thereby greatly improving the reinforcing effect and the stability of the structure. The anchor device mainly comprises an anchor cup, an anchor clamp, a bolt, and the like. The fixed position of the pultruded fiber reinforced resin rod is unnecessarily adhered by an adhesive, so the work efficiency is greatly improved, and the cost is reduced.

Description

technical field [0001] The invention relates to an anchoring device at the end of a pultruded fiber reinforced resin rod, which belongs to the anchoring device for building structure reinforcement. Background technique [0002] At present, due to the protection of the environment and forest resources in various countries, high-quality wood for the production of engineering wood composite materials is relatively scarce. Countries will focus on how to use artificial fast-growing wood and low-quality wood. Local reinforcement of pultruded fiber-reinforced resin rods is a key technology to solve this problem, and this technology is easy to operate, low in cost and good in reinforcement effect. The key problem of the local reinforcement technology is that the end of the pultruded fiber reinforced resin rod has weak adhesion, which may easily cause shear failure of the adhesive layer. Contents of the invention [0003] The purpose of the present invention is to provide a pract...
