Reinforcement bar straight thread connection technology and characteristics

Introduction: Now in the 21st century, we are in the era of high technology, and people’s current lives have also been greatly changed because of high technology. For example, with computers, we can know everything about the world without leaving home; With cars, we no longer have to walk to far places. In today's life, we can see some steel products everywhere, and these steel products all need some connectors to connect them. The steel bar straight thread is such an item that can link the steel bars together. The editor will introduce it to you below. Reinforcement bar straight thread connection technology.

Processing of straight thread threads for steel bars:

1. Preparation before processing:

a. All operators, technical management and quality management personnel involved in joint construction , all should participate in technical training; operators should be certified to work after passing the assessment.

b. The steel bars should be straightened first and then cut. The end face of the cut should be perpendicular to the axis of the steel bar. There should be no horseshoe shape or deflection. Gas cutting should not be used to cut the steel bars.

c. The sleeve provided by the manufacturer should have a product certificate; the threaded holes at both ends should have protective covers; the surface of the sleeve should have specification marks.

2. Straight thread thread head processing:

a. Adjust the minimum size of the inner hole of the thread rolling head and the knife ring according to the steel bar specifications, adjust the rib stripping stop and the rolling stroke The switch position ensures the length of rib stripping and rolling threads.

b. When processing steel bar threads, use water-soluble cutting lubricant; when the temperature is below 0°C, 15%-20% sodium nitrite should be added. Machine oil must not be used as lubricant or no lubricant should be added. Lubricant thread.

c. Operators should check the appearance quality of steel wire heads one by one, check whether the tooth shape is full, and have no broken teeth or bald teeth. The qualified wire heads should be covered with protective caps to protect them.

Straight thread connection technology of steel bars:

1. Main technical content: main process of cutting the ends of steel bars flat;

2. Professional rib stripping and rolling machine Peel off the ribs and roll the thread at the end;

3. Use connecting sleeves to butt the steel bars.

Technical features:

1. Suitable for steel bar connection construction in reinforced concrete structures of various structures that can withstand two-way forces of tension and compression.

2. Energy saving and material saving.

3. Can be connected in all directions.

4. It can be prepared in advance, does not occupy the construction period, and can be constructed around the clock.

5. Easy and fast operation, fast construction speed.

The above is the relevant technology sharing about the straight thread of steel bars introduced by the editor. The editor feels that the current social development is getting better and better, and the lives of the general public have become more convenient. In our daily life, steel bar straight threads are widely used. We often see a lot of steel products. In many factories, steel bar straight threads are part of machinery and a necessity. This is the editor's introduction, I hope it can help friends in need.
