The recent damages caused by earthquakes in neighboring countries are beyond imagination, and Korea, which is classified as a middle and weak area, is not safe from such natural disasters.
     Moreover, domestic earthquake preparedness environment is more than 80% of existing building facilities are almost defenseless against earthquakes. In particular, multi-family houses, which are the majority of middle and low-rise structures, and school facilities that should be used as evacuation sites for residents in case of emergency Now, only the seismic reinforcement is starting.
     In general, seismic reinforcement works of existing building facilities are carried out outdoors except for special cases. This can be said to not limit the usability of the existing building as possible.

Such work is most often the case of measuring the opening size (horizontal and vertical length) of the existing reinforced concrete structure 10, and pre-fabricated reinforcing steel structure 11 to be used in accordance with the installation in the field, easy installation To do so, a certain distance must exist between the reinforcing steel structure 11 and the existing reinforced concrete structure 10. If there is almost no gap between the reinforcing steel structure 11 and the existing reinforced concrete structure 10, the work itself of inserting the heavy reinforcing steel structure 11 into the opening space of the existing reinforced concrete structure 10 is very Because it is difficult. In addition, the opening of the existing reinforced concrete structure 10 may be curved in some areas instead of maintaining an exact square shape, in which case it may interfere with the reinforcing steel structure 11 may not be installed itself. ,
In addition, if the gap between the existing reinforced concrete structure 10 and the reinforcing steel structure 11 becomes too wide, the installation work is easy, but the seismic reinforcement of the seismic reinforcement can not be guaranteed after the seismic reinforcement. There is a problem that the effect is reduced.
Therefore, according to the size of the opening to which the seismic reinforcement is made, there is no choice but to manufacture the reinforcing steel structure 11 to be applied only to the corresponding work site, and even if the size of the opening is slightly changed, the existing reinforcing steel structure 11 cannot be utilized. Reinforcing steel structure 11 must be manufactured separately.
In addition, when the reinforcing steel structure (11) is installed, the work to pour the mortar is cured, this mortar placing work is to reinforce the steel to surround the reinforcing steel structure (11) and surround the formwork to surround the reinforced steel When the mortar curing is completed after installation, there is a problem that the cumbersome work of dismantling the installed formwork is accompanied.
Therefore, it is possible to absorb the change in the size of the opening within a certain range so that the seismic reinforcement can be made more conveniently, thereby increasing the versatility and ensuring sufficient seismic strength and integral behavior with the existing reinforced concrete structure 10, and convenience of mortar pouring work.
