Embodiment 1）

[0084] In Example 1, the multilayer window structure 20 having the structure explained in the above-mentioned embodiment mode was manufactured. In addition, the constitutional conditions of the multilayer window unit 17 constituting the multilayer window structure 20 are as follows.

[0085] A substantially rectangular transparent glass having a length of 986 mm x a width of 2036 mm x a thickness of 4 mm was used as the one side window plate 21 . As the other side window panel 23, a substantially rectangular window panel made of transparent polycarbonate having a length of 984 mm x a width of 2033 mm x a thickness of 8 mm was used. The peripheral portion (plane difference surface 23 b ) of the other side window panel 23 is formed to have a width of up to 185 mm and a thickness of 5 mm, which is 3 mm thinner than the center portion of the other side window panel 23 . In addition, under the condition of 18° C. to 25° C., the center CP of the other window plate 23 protrudes by 0...

Abstract

This multi-layered window structure comprises: one window pane comprising glass; an other window pane comprising polycarbonate, smaller in both height and width than the one window pane, and formed to a thickness of 5 mm to 30 mm; a hollow annular spacer disposed so as to extend along edges of the one window pane and the other window pane, and having holes facing an air layer between the one window pane and the other window pane; and a primary sealer comprising an elastic body, with a thickness of 0.5 mm or more and a width of 6 mm or more, that extends along the edges of the one window pane and the other window pane, and is disposed between the one window pane and the spacer, and between the other window pane and the spacer.

Description

technical field [0001] The present invention relates to multilayer window structures. Background technique [0002] In recent years, as a window structure of a railway vehicle traveling at high speed, a multi-layer window is known in which an air layer is provided between two transparent plates from the viewpoint of sound insulation and heat insulation (refer to patent document 1). Since the pressure difference between the internal pressure of the air layer and the external pressure fluctuates greatly, such a multi-layered window is supported by a frame material. In addition, in order to make the air layer airtight, sealing materials, polymer coatings, etc. are filled between the frame material and the multi-layer window. [0003] In addition, in recent years, as the speed of railway vehicles has increased, large window panels have been required from the viewpoint of viewing scenery from inside the vehicles. However, when driving at high speed in a cold region, there are ...
