Thermal insulation structure having shear rebars and tension bars integrally formed in thermal insulation unit

A thermal insulation structure, comprising:

• a thermal insulation unit provided between a floor slab and a balcony slab;
• an upper first tension rebar and a lower first tension rebar buried in the floor slab;
• an upper second tension rebar and a lower second tension rebar buried in the balcony slab;
• an upper connection tension rebar passing through the thermal insulation unit and connecting respective opposite ends of the upper first tension rebar and the upper second tension rebar and a lower connection tension rebar passing through the thermal insulation unit and connecting respective opposite ends of the lower first tension rebar and the lower second tension rebar;
• shear rebars spaced apart from each other in parallel in the thermal insulation unit and connecting the upper connection tension rebar and the lower connection tension rebar;
• and
• at least one auxiliary shear rebars provided between the shear rebars and connecting the shear rebars;
• and
• an upper coupling cover installed on a top surface of the thermal insulation unit and a lower coupling cover installed on a bottom surface of the thermal insulation unit, wherein a bottom surface of the upper coupling cover has a larger width than the top surface of the thermal insulation unit, and a top surface of the lower coupling cover has a larger width than the bottom surface of the thermal insulation unit, and wherein the upper coupling cover and the lower coupling cover are connected to concrete of the floor slab and the balcony slab.
