Description

  The present invention relates to a kind of pure axial force bending prevention bundling device, and more particularly to a bracing device that can withstand pure axial force and has a vibration absorbing effect.

(1) Traditional braces are folded or broken locally when subjected to axial pressure, the loop curve reveals the action of gradual reduction and reduction of strength, and the material fully absorbs its energy absorption capacity. Before exerting, cuts occur due to excessive stress and strain concentration. For many years, seismic engineering researchers have been conducting research to improve traditional diagonal support performance, and each organization has been presented with a series of straps that can prevent folds from breaking as a substitute for traditional braces. .
The flexion binding brace consists of a main force receiving unit and a binding unit, and the axial force (tensile force and pressure) of the brace is received by the main force receiving unit, and the binding unit provides support to the main force receiving unit from the side. , Prevents bending due to the pressure of the main force receiving unit If the main receiving unit can be prevented from bending under axial pressure, the axial strength and stretchability of the main receiving unit can be effectively developed, and the energy absorption capacity of the steel material can be fully exhibited.
For this reason, how to control the action of the main receiving unit receiving axial force and to enhance the anti-bending effect by the bundling unit is the focus of research and improvement of the anti-bending bundling brace.
(2) There are two types of bundling units that are known to bend and prevent bundling, such as those that inject cement slurry into the inside and those that provide bundling support from the side with a pure steel pipe. However, in any binding unit, rigid or semi-rigid joints are used to join the ends of braces and structural materials. At this time, the braces are curved and a secondary bending moment effect is generated, resulting in high axial pressure. When receiving, the strength of bracing decreases rapidly and is easily destroyed. In addition, for the well-known bending prevention bundling unit, a multi-steel tube pure steel type is used. It is easy to generate a bending state, and it is not possible to provide a bending prevention effect by binding effective for the main force receiving unit.

  For this reason, there is a need for a bracing device having a seismic energy absorbing function that is efficient, reliable, and easy to construct, in response to the disadvantages of the above-described bending prevention bundling type bracing.

  The next purpose of the present invention is to provide a kind of pure axial force bending prevention bundling device, which is combined with a rotary pivot hole structure at the end of the braces, so that the pure axial force action is applied when receiving force. When subjected to endurance, compression, or tension, both shall yield stably and fill their loop curves, and have high energy absorption capacity due to bracing plastic deformation, meeting the requirements of seismic engineering and practice.
