Problems solved by technology

However, this connection method needs to be processed and prefabricated in advance when it is applied in engineering, which is time-consuming and labor-intensive. It has the following disadvantages: 1) The steel bar must be processed and prefabricated in advance, which increases the prefabricated process and prefabricated costs; 2) After processing The thread head should also be properly protected, once it is damaged, it cannot be connected and installed: 3) The threaded anchor plate needs to ensure its quality requirements in both processing and installation, and the anchor plate involved in this patent has only one installation link. Control link; 4) The specification and size of steel bar thread processing required by the manufacturer of the general anchor plate are inconsistent with the thread parameters of the steel joint used on the construction site (when the supplier of the anchor plate and the joint is not the same), the thread head is separated separately The processing is more troublesome and difficult to manage. Once the wire ends are mixed, it will easily cause quality accidents. Therefore, when the number of anchor plates in the project is small, the supplier of the anchor plates is unwilling to supply them, but the design has clearly required the use of mechanical anchors. Board up
[0005] Therefore, in the current situation where the domestic labor cost is greatly increased, the method of threaded connection is becoming more and more inconvenient, and the overall cost is high, which is not convenient for engineering application.

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.

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...
