Embodiment Construction

[0013] Let’s illustrate with an example in conjunction with the accompanying 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 material of the anchoring fixture 2 is aluminum alloy, and use 60-140 The target sand has been sandblasted; put the anchoring fixture 2 on the outside of the pultruded fiber reinforced resin rod 4, put it into the anchor cup 1, and hit the thicker end of the anchoring fixture 2 with a heavy object to make it clamp the pultruded Fiber-reinforced resin rod 4; put the above-mentioned connected structure into the pre-opened notch at the bottom of the glued wood beam, use instant glue to bond the position where the anchor cup is close to the notch of the wooden beam, and fix the anchor cup 1 to the on the 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...
