Description

Connection structure

The present invention relates to a connecting structure, in particular to a connecting structure for fixing two steel bars to each other.

According to the general steel bar size, there are fixed length specifications, and many construction projects have a considerable height or width (such as high-rise buildings), so it is one of the most common construction methods to fix steel bars to each other; Common methods of fixing include: artificial lap joint, threaded joint method, welding method, etc., and for the relevant technical personnel, no matter which way is used for fixing, it is necessary to consider the two steel strips after fixing. Resistance to tensile and seismic resistance; in other words, in consideration of conditions such as tensile strength, various methods of fixing have certain limitations and difficulties.

In the current most common threading method, it is attached to the end of the two steel bars to be fixed, and then the sleeve with the corresponding thread is used to lock the two steel bars to each other. However, there are many problems with this method. For example, the number of steel bars to be fixed in any construction site is huge. If each steel bar is to be used one by one, it is not only time-consuming and labor-intensive, but also directly purchases a car. The steel bars of the teeth will greatly increase the cost; in addition, the steel bars behind the teeth will have a smaller sectional area, which will weaken their own strength, and whether it is the thread processing of steel bars or sleeves, If there is a slight deviation, it will probably weaken the strength of the overall fixation. Therefore, how to make the two steel bars can be fixed in a low cost and fast manner under the conditions of tensile strength, etc., is one of the important topics in the industry.
