Description

Improved shock-resistant stirrup

This creation is about an improved shock-resistant stirrup, especially an improved shock-resistant stirrup that is to be used in the pre-group reinforcement method and the completion method, and can avoid the problem of weak angle and main reinforcement conflict.

Reinforced steel building materials are a material that is almost indispensable for structural safety for modern concrete buildings. Through different ways of using, it can effectively enhance the structural safety and seismic resistance of the building.

However, although there are already many reinforced or tied structures that are not ready for loading, to improve the structural safety of the building, there are still many shortcomings.

In the case of a single closed stirrup, the winding method is as shown in FIG. 1A, and the single closed stirrup 2 has a first hook portion 21, a second hook portion 22, and a rib 23, and the first hook portion 21 The second hook portion 22 can overlap and form a frame through the rib 23, but the single closed stirrup 2 of this type is as shown in FIG. 1B, and when it is wound around the longitudinal main rib 1, there is The following shortcomings occur: (1) having a semi-weak angle at the starting point and ending point of the stirrup; (2) having a main rib collision at the weir, thus easily affecting effective depth or lap joint; (3) when applied to no floor slab When the side or the fly beam is structural, the single side without floor slab needs to judge the direction of the stirrup and the flying beam needs to be staggered.

In the case of the conventional closed stirrup, the winding method is as shown in FIG. 2A. The conventional closed stirrup 3 has a stirrup body 31 and a cap 32, wherein the stirrup body 31 has a first hook portion 311. a second hook portion 311 and a rib 313.
