Description

The present invention inserts a spring inside of the pipe, by compacting the cured material, a method for manufacturing a resistant Shenyang structural material excellent in vibration resistance.

  In recent years, large-scale earthquakes have occurred, and earthquakes in multiple areas are expected in the future. Therefore, in order to prepare for the occurrence of a large earthquake that is expected in the future, various measures are being taken nationwide with reference to past earthquake disaster examples.

  Among various countermeasures, people are more interested in housing. Specifically, there are countermeasures based on seismic diagnosis and seismic reinforcement. As one of countermeasures, various indoor earthquake-resistant shelters have been proposed for general houses that form evacuation spaces where people can evacuate when an earthquake occurs.

  As a countermeasure against this, the technique disclosed in Patent Document 1 is known. In the technology disclosed in Patent Document 1, in an indoor earthquake-proof shelter 100 that forms an evacuation space having a frame structure, all or part of the frame member 101 constituting the frame structure is formed of a square pipe material. A reinforcing material 102 that reinforces the bending deformation is provided inside the pipe material, and the reinforcing material 102 is a fiber reinforced sheet bonded to the inner surface of at least one side of the square pipe material so as to extend in the longitudinal direction.

  According to this indoor earthquake-resistant shelter, all or part of the frame member 101 constituting the frame structure is formed of a square pipe material, and the reinforcing material 102 that reinforces the bending deformation is provided inside the square pipe material. It is possible to ensure a wide entrance / exit after ensuring sufficient rigidity. Moreover, since the reinforcing material provided inside the square pipe material does not come into contact with a person or an object, there is no risk of damage over a long period of time.

With the above configuration, the pipe material is arranged on the inner side along the longitudinal direction of the pipe material so that the spring is arranged apart from the shaft arranged at the center of the pipe material, so that the spring is omnidirectional due to the earthquake. In contrast to the vibration and vibration from the material, it absorbs the energy of vibration and vibration by bending, avoids bending, and the inside of the structural material is filled with a hardened material having high strength and impact resistance. Sufficient strength can be secured to withstand the vibrations and vibrations from multiple directions when an earthquake occurs.

  In addition, with the above configuration, a long shaft made of steel material is arranged inside the pipe material, so that higher strength can be obtained, and the hardened material is agitated by rotating the spring around the shaft. Therefore, the inside of the pipe material can be filled with the hardening material without introducing a void.
