Straight thread sleeve connection method Rebar connection sleeve features and precautions for use

In fact, many people still understand the sleeve. The sleeve refers to the short name of the socket wrench and is a special tool for tightening or loosening the screws. Rebar connection sleeves are a special product for the mechanical connection of rebar and are divided into cold extrusion sleeves, tapered thread sleeves and straight thread sleeves. Next, in order to help more clearly understand the steel connection sleeve, the following Xiaobian will introduce the connection method of the straight thread sleeve, the characteristics of the steel connection sleeve and the precautions for use.

　　 Straight thread sleeve connection method

The method of connecting the straight thread sleeve is to strip the longitudinal ribs and the transverse ribs of the steel bars to be connected by a method of cutting by a thread rolling machine, and then directly roll into a straight thread and connect them with a special straight thread sleeve. , forming a connection to the reinforcement.

The rib-peeling straight rolling screw connection technology of steel bar is the first invention of technology at home and abroad, reaching the international advanced level;

The stripping rib rolling straight thread connection technology has advantages of high efficiency, convenient and rapid construction methods, energy saving, high efficiency, and stable and reliable connection quality. It has been favored by the majority of construction units and owners, and is a new type of straight thread connection technology. .

　 Rebar connection sleeve features

1, the use of international 45 steel, special manufacturing processes, high dimensional accuracy, reliable quality.

2, can be connected to Ф16-Ф40mm HRB335 and HRB400 ribbed rebar.

3, after the National Construction Engineering Quality Supervision and Inspection Center testing, to meet the JGJ107-2003 Class I connector standards.

4. Three series of standard type, positive and negative thread type, and different diameter type, 52 types, which can meet the same diameter, different diameter and adjustable length and direction of horizontal, vertical, oblique and other parts of the building structure. The connection reinforcement needs.

　　 Rebar connection sleeve precautions

There are two ways to eliminate the backlash of the reinforcement connecting sleeve:

1. Through the top of the steel wire in the connecting sleeve, the head of the steel wire under the action of the top force, the thread of the thread head and the thread of the connecting sleeve are closely fitted to eliminate the thread gap.

2, by the end of the end of the wire and the end of the connection sleeve tight, eliminate the thread gap, this method can not match the top of the wire in the middle of the sleeve, the same can achieve the effect of eliminating the thread gap.

However, it should be noted that the difference between the end face tightness and the large-diameter self-locking at the screw thread tail. According to the above analysis, whether or not the end face of the reinforcing steel material is straight is the first important process of quality control for the production of rolled straight-threaded steel rebars, and it is also an important part that most of the use units can easily overlook. In addition to the steel cutting method should pay attention to the cutting method, it should also pay attention to the steel wire to be processed when the thread is bent should be straightened, the steel bar bending will cause the thread screw head thread incomplete thread out of tolerance, not only affects the wire The appearance quality of the head, in severe cases, will also have a certain influence on the carrying capacity of the joint.

Rebar connection sleeves are suitable for the reinforcement connection construction in reinforced concrete structures of various types of structures subjected to pulling and pressing two-way forces, which have the advantages of material saving, energy saving, and not limited by the composition and type of steel bars. Straight thread sleeve connection method, the characteristics of reinforced steel connection sleeves and the use of attention to the small series for everyone to introduce here, I hope everyone can gain from it.
