Metal rib material and non-metal rib material connecting device and method

Abstract

The invention belongs to the technical field of connection of different rib materials, and relates to a metal rib material and non-metal rib material connecting device and method. A first connecting pile casing and a second connecting pile casing correspondingly sleeve the end of a non-metal rib material and the end of a metal rib material, and the first pile casing and the second pile casing are connected through a two-way nut. Threads are arranged on the inner walls, close to the two-way nut, of the first connecting pile casing and the second connecting pile casing, annular grooves are formed in the other parts of the inner walls, epoxy resin is injected into the annular grooves, therefore the first connecting pile casing is tightly attached to the non-metal rib material, and the second connecting pile casing is tightly attached to the metal rib material. A rubber pad is arranged at the junction of the threads on the second connecting pile casing and the annular grooves, so that the epoxy resin is prevented from blocking a screw hole matched with the two-way nut; and the metal rib material and non-metal rib material connecting device is simple in structure, convenient to assemble and reliable in performance, the two-way nut is adopted for connecting the two kinds of rib materials, the anchoring performance is more reliable, the epoxy resin is adopted between the rib materials and the connecting pile casing, the bonding effect is achieved, the water stopping effect can be achieved, and the metal rib material and non-metal rib material connecting device is convenient, fast, time-saving and labor-saving.

Description

Technical field: [0001] The invention belongs to the technical field of connecting different bars, and relates to a device and method for connecting metal bars and non-metal bars. Background technique: [0002] At present, with the increase of the buried depth of the building structure foundation, the amount of underground structures such as underground diaphragm walls and anti-floating anchors is increasing. The problem of metal corrosion has become increasingly prominent in the field of underground anti-floating and structural reinforcement. Although a series of anti-corrosion measures have been taken, due to the nature of the metal matrix, it is difficult to guarantee its durable workability as an underground permanent structure. In order to solve the above problems, many scholars have proposed non-metallic reinforcements, such as glass fiber reinforcements, basalt fiber reinforcements, carbon fiber reinforcements, etc. Tests have proved that non-metallic reinforcements c...

CN201320334830.9 proposes a connector capable of connecting a single FRP stranded wire. The connector consists of a clip, a metal sleeve, an anchor cup, and a connecting sleeve. It has a better connection effect for the same non-metallic stranded wire. But it is not conducive to the promotion of practical engineering applications; CN201020261373.1 proposes a device for FRP bars and steel strand connectors and composite cables, which are mainly constructed by steel hinge wire end connectors, steel hinge wire anchors, hollow connectors, etc. Composition, high stability, but complex structure, and not suitable for permanent structure
