Brief Introduction of Parallel Thread Rebar Couplers

图片
The  parallel thread rebar coupler  is one of the smallest and most effective coupler systems. It is widely used in projects that are large and high coupler volume. Both ends of the bars are enlarged, parallel threads are enlarged, parallel threads are cut into two sides two adapt the thread coupler. The couplers should be installed by tubes or wrenches. Calibration is not necessary. Paraller thread rebar couplers can produce full strength joints, yet they are the smallest of all couplers, which means they are the best choice for large projects that needs a large number of couplers. The end of each couplers are squares enlarged by cold forging, which increases the core diameter and makes sure that joints are stronger than pipes.

The Classification of The Rebar Couplers

图片
Rebar couplers  are combinators to connect rebars, with internal threads to match the screw threads. It has 6 different types and can be deployed in these different ways. 1. Standard connection Designed for situations that rotations are possible and limitless. By using a steel bar, meets at opposite side of the end force of the bridge piece. Standard and diameter-varied couplers are optional. 2. Lengthened connection Designed for situations that rebars are too long and dense, rotations are limited. Couplers are fully screwed in the lengthened thread of a rebar in advance, then reverse screwed in the end thread of the rebar that is being connected. To lock the coupler, just twist the rebar for half to one turn. Standard couplersare optional. 3. Locknut-added connection Designed for situations that rebars can't rotate, such as hooked rebars and dockings of bridges, place piles reinforcement cages. Lock the coupler by screwing the locks and rebars in the lengthend thread in advance, t

The Advantages of Rebar Sleeve

图片
Rebar sleeves  is a rebar connector with the insider threads that are correspond to the head threads. Its length is a key factor in determining the qualification of the rebar connection sleeves. Rebar sleeves are primarily used in construction industry, it brings convenience to the industry and generates efficient. 1. Using rebar sleeves in the construction industry can reduce the material usage greatly. It is also easy to operate, unrestricted by the type rebars. Customize in advance is available, which won’t take your duration and it has a high processing efficiency. 2. Rebar sleeves is easy to be connected, not only handy but also convenient. Electricity is not necessary during construction. All-weather construction is acceptable. 3. Rebar sleeves are able to connect horizontal, vertical and inclined HBR335,HBR400 same diameter or different diameter rebars. These are the introduction of the advantages of rebar sleeves.  Changsha DLADTO Rebar Splice Co., Ltd  is a professional produc

Disassembly steps and installation inspection of rebar couplers

  Disassembly steps for  rebar couplers : Insert the tip of the remover into the hole of the wire sleeve, press the handle firmly, and turn it counterclockwise to remove the rebar couplers.   Installation detection of rebar couplers: After the rebar couplers are installed, the threaded hole tolerance zone depends on the rebar couplers profile manufacturing tolerance and the rebar couplers mounting hole thread tolerance zone, the former is controlled by the rebar couplers manufacturer, the latter mainly depends on the rebar couplers mounting hole tapping accuracy, usually formed 6H grade, can reach 5H, 4H grade tolerance zone when the precision is high, the unified thread standard is 2B, 3B. The bottom hole thread can be inspected with the corresponding grade of plug gauge.   Changsha DLADTO Rebar Splice Co., Ltd  is a division of ADTO GROUP. We are a comprehensive company who mainly focus on design and research, production, sales service of supplying the construction and industrial sec

What tests are required for a qualified rebar coupler?

Processing and inspection of straight threaded steel bar connecting coupler . (1) The material of the straight threaded steel bar connecting coupler : It is made of hot-rolled alloy structural round steel. (2) The size of the straight-threaded steel bar connection coupler should match the tooth shape and number of the tapered threads at the end of the steel bar, and should meet the requirements that the bearing capacity is higher than that of the steel base material. (3) In order to ensure the quality of the product, the straight-threaded steel bar connecting coupler is processed by a professional processing factory. The outer surface of the couplers of various specifications are marked with steel grade and specification marks. After the coupler is processed, the taper holes at both ends must be sealed with the corresponding sealing covers. (4) For the acceptance of the straight-threaded steel bar connection coupler, the specification, model and mark of the coupler should be checked, t

The differences between rebar coupler

The advantages of the direct rolling straight threaded rebar couple r are: the thread processing is simple, the equipment investment is small, the disadvantage is that the thread accuracy is poor, and the false thread phenomenon exists. Due to the uneven thickness of the steel bars, large tolerances, and inconsistent thread diameters, the on-site construction is difficult, and the coupler and the thread head are inconsistent with the tightness, and some joints may be pulled off. Due to the change of the steel bar diameter and the influence of the transverse and longitudinal ribs, the service life of the rolling wheel is reduced, the additional cost of the joint is increased, and the vulnerable parts of the construction site are frequently replaced. Rolling ribs and rolling straight threaded reabar coupler: This kind of connection joint uses special extrusion equipment to pre-flatten the transverse and longitudinal ribs of the steel bars, and then roll the threads, the purpose is to red
