How To Adjust Positive And Negative Thread On Thread Cutting Machine ?

1   Remove the  eccentric bushing  and eccentric shaft from the thread holder, loosen the screws first, and then use a special wrench for the eccentric bushing to rotate the eccentric bushing 180 degrees . Then, place the loosened screws into the screw hole after the rotation of 180 degrees and tighten them (the rolling head and rib stripping head are equipped with 3 eccentric bushing, each with a 180 degree rotation, and tighten them by changing the screw hole). 2 Install the threading roller and place it counterclockwise in 1-2-3  (POSITIVE THREAD)    Install the threading roller and place it anticlockwise in 3-2-1  (NEGATIVE THREAD) 3 Upper the rib stripping machine head, tighten the screws, adjust the test bar, and start working

Remedial Measure for Incorrect Position of Rebar Connector

图片
The issues should be considered comprehensively during the construction of   steel bar connectors : the position of the joint should be arranged at a position with less stress, and the ground joints of adjacent steel bars should be properly staggered to facilitate operation. Choosing the right type coupler and thread directing according to the actual situation of the floor and reinforcement to adjust it in time. Remedial measures for incorrect position of rebar connectors If the position of the joint is not correct, the first thing to do is contact the designer, and the following measures usually be taken to remedy it. 1. The position deviation of the joint is small, which can be solved by adjusting the bending angle of the connecting steel bar, but it must meet the requirements of 1/6 of the specification and get the designer approval in advance. 2. The joint position deviation of the steel bar connector is large. Edge beams can be constructed first at the connector locations, convert

Methods of Mechanical Connection

The   mechanical connection   methods of steel bars include: ribbed steel sleeve extrusion connection, steel bar taper thread connection and steel bar equal-strength thread sleeve connection. 1. Sleeve extrusion connection joint: the joint formed by the plastic deformation of the steel sleeve of the connecting piece and the tight bite of the ribbed steel bar through extrusion force. 2. Tapered thread connection joint: a joint formed by the special tapered thread at the end of the steel bar and the tapered thread of the connecting piece. 3. Equal-strength straight thread connection joints: The quality of the joints is stable and reliable, and the connection strength is high, which can be compared with the sleeve extrusion connection joints, and it also has the characteristics of convenient and fast construction of the tapered thread joints. Changsha DLADTO Rebar Splice Co., Ltd  as a division of  ADTO Group . We are a professional rebar coupler producer, we have been in this field for a

Reinforcement Joint Stagger Distance Specification

1. The joint should be set at less stress place of steel bar. Two joints should not be set in a steel bar. The joints of longitudinally stressed steel bars in the same reinforcement members should be staggered from each other. 2. It is strictly forbidden to use overlapping joints diameter over 16mm steel bars, which should take welded connection or  mechanical connection . Illustrate: 1. Lap joint connection: The lap joint length should meet the design and specification requirements, and the adjacent steel bar joints should be staggered by 50%; the joint stagger height should be 1.3 times over the lap joint length. 2. Mechanical connection: the finished concrete surface of the joint should over 50cm, and the joints of adjacent steel bars should be staggered by 50%; the height of joint stagger should not be less than 35d. 3. Welding connection: the finished concrete surface of the joint should not be less than 50cm, and the adjacent steel bar joints should be staggered by 50%; the heigh
