Anchoring device for taper sleeve-locking reinforcements and anchoring method thereof

Abstract

The invention relates to an anchoring device for a taper sleeve-locking reinforcements and an anchoring method thereof, and belongs to the technical field of reinforced concrete anchoring. The anchoring device comprises a plurality of clamping sheets and taper sleeve anchoring plates at the outer sides of the clamping sheets, wherein each clamping sheet is provided with a tooth-shaped inner surface and a single-conical-surface outer surface, and reinforcements to be anchored are wrapped and clamped through the tooth-shaped inner surfaces; each taper sleeve anchoring plate is in a head-shoulder integrated shape and provided with a conical hole at the centre, and the clamping sheets and the reinforcements to be anchored sequentially sleeve the inner centres of the conical holes and locked simultaneously through the taper sleeve anchoring plates; the tooth-shaped inner surface of each clamping sheet is provided with a plurality of spaced trapezoidal teeth, and threads for anchoring are not needed at the end parts of the reinforcements to be anchored. The anchoring device disclosed by the invention omits the prefabrication link of reinforcement thread machining, saves the machining structure and the machining cost of the prefabrication link, and is fast, convenient and reliable to install, and easy for control quality.

Description

technical field

[0001] The invention relates to a steel bar anchoring device and an anchoring method, in particular to a tapered sleeve locking steel bar anchoring device and an anchoring method that do not need to be provided with threads at the end of the steel bar, and belongs to the technical field of reinforced concrete anchoring. Background technique

[0002] "Reinforcement mechanical anchoring technology" has been applied for decades in western economically developed countries, and its application in my country began in the past 10 years.

[0003] For those skilled in the art, the traditional anchoring of steel bars used in reinforced concrete basically uses "bent bar anchoring". Inconvenience etc.

[0004] With the advancement of technology, the steel mechanical anchor plates currently used in China are mostly straight threads and welded connections. The steel anchor plates are made of circular anchor plates with internal threads and steel bars with threads. Such a...

Examples

Embodiment 1

[0033] Such as Figures 3 to 4 As shown, a tapered sleeve locking steel bar anchorage device of the present invention includes a clip 5 and a tapered sleeve anchoring plate 6 on the outside of the clip 5, the clip 5 is two, three or four, and it has a toothed inner surface (not shown in the figure) and the outer surface of the single cone surface, the multi-piece clip 5 wraps the steel bar 4 to be anchored through the tooth-shaped inner surface, and the multi-piece clip 5 is symmetrically arranged around the steel bar 4 to be anchored. 5. The outer end is flush or not flush with the outer end of the steel bar 4 to be anchored when placed. The tooth-shaped inner surface of the clip 5 is arc-shaped, and is used to closely fit and occlude with the outer surface of the steel bar 4 to be anchored. The taper sleeve anchoring plate 6 is in the shape of head and shoulders, and its cross-sectional shape is circular, square, oval or polygonal, and its center is provided with an axially...

Embodiment 2

[0040] Such as Figures 3 to 4 As shown, another taper sleeve locking steel bar anchorage device of the present invention has a taper sleeve anchor plate 6 that is a cylinder, a square cylinder or a polygon cylinder of equal thickness. Other settings, connection methods and construction methods are the same as in Embodiment 1, and will not be repeated here.
