Meanwhile, the bonding medium 130 is formed to a thickness of 6 to 30 mm, and the steel bar 131 formed on both sides of the inside of the bonding medium 130 is formed as a hollow part 132 (hollow part) The polyurethane foam 133 is filled in the hollow portion so as to prevent the bending of the steel rod 131 due to the impact.

Hereinafter, the operation and effect of the present invention will be described.

3 to 4, the multi-layered glass 100 installed on the building includes an outer glass 110 installed on the outside of the window with a space layer 140 interposed therebetween by a bonding medium 130, And an inner glass 120 installed inside the window to fill the space layer 140 formed by the bonding medium 130 with an inert gas such as air, nitrogen or argon gas, So that the sound insulation effect can be obtained.

At this time, the bonding medium 130 is configured to have a thickness of 6 to 30 mm, and the thickness of the bonding medium 130 When the thickness of the bonding medium 130 is more than 30 mm, the bonding medium 130 may be easily deformed due to an impact generated by frequent opening and closing of the window due to the too thin thickness. The window frame is thickened due to the thickness thereof, so that deformation occurs easily. When an external impact is generated, the impact force is directly transmitted to the joining portions of the inner and outer glass and the middle shutoff plate 150 to cause breakage of the glass, Glass (1 10 and the inner glass 110. It is preferable that the bonding agent 130 is formed to a thickness of 6 to 30 mm.

The steel bar 131 formed on both sides of the inside of the bonding medium 130 is formed into a hollow portion 132 and then a polyurethane foam 133 is formed inside the hollow portion 132. [ The joint medium 130 and the steel bar 131 inside the joint medium 130 are easily bent due to the buffering action of the polyurethane foam 133 due to the impact generated during frequent opening and closing of the window of the multi- .
