  The problem to be solved by the present invention is that, in the case of the conventional double-layered sheet glass structure, a new sheet glass is laminated as a retrofit on the indoor side of the existing sheet glass in the case of a reform etc. Construction for the corner part of the object is not possible, the sheet glass for retrofit becomes impossible to be transported by the elevator due to its size and weight, and in the case of a high-rise building, there is a limit to the floor that can be constructed That is the point.

  In order to solve the above-mentioned problems, the structure of the multi-layer plate glass according to the present invention is the indoor side on the indoor direction side of the first plate glass on the outdoor side, and the size is smaller than the first glass plate. The second sheet glass is airtightly polymerized and fixed by the sealing material via a spacer along the periphery of the second sheet glass, and the above-mentioned edge of the first glass sheet is from the edge of the second glass sheet It is characterized as having a protruding configuration.

  In the multi-layer sheet glass structure according to the present invention, the spacer is a pipe body having a width for maintaining the distance between the first and second sheet glass, and the pipe is filled with a hygroscopic agent. It is characterized by

  Furthermore, the structure of the multi-layer plate glass according to the present invention is characterized in that argon gas or krypton gas is enclosed in a hollow portion formed by the first plate glass and the second plate glass.

  The structure of the multi-layer plate glass according to the present invention is characterized in that an angle member is attached to the lower end portion of the second plate glass described above.

  The structure of the multi-layer plate glass according to the present invention is characterized in that the distance between the periphery of the first plate glass and the periphery of the second plate glass is at least 5 mm or more.

  The structure of the multi-layer plate glass according to the present invention is configured as described above. As described above, the structure of the multi-layer sheet glass according to the present invention is manufactured before the construction, and the work on site is to attach this pre-formed multi-layer sheet glass to the frame or to the frame in advance. In the mounted state, the frame is set at a predetermined position.

  Therefore, it is possible to prepare in advance the manufacturing preparation for the building and the corner part of the building, and to cope with various mounting requirements, as well as the opening of the building and the building. Also, it can be adopted as a guard of a veranda and can correspond to a back mullion structure, and the thickness of the plate glass can also cope with a high wind resistant pressure finish of 12 mm or more, if necessary.

  This multi-layered sheet glass structure is particularly effective for new construction and rebuilding, but it can naturally be applied not only to high-rise buildings and buildings but also to detached houses and the like.

It is a front view which shows the structure of the multilayer plate glass which implemented this invention. It is the perspective view which partially broken similarly. It is a perspective view shown as a partial cross section. It is a fragmentary sectional view which shows the state which attached the angle material.

  It realized as having shown as a drawing and having constituted as explained in the example.

  Next, one preferred embodiment of the present invention will be described with reference to the drawings. In the figure, 1 shows a multi-layered sheet glass to which the present invention is implemented. The multi-layer plate glass 1 is an outdoor side, and has a rectangular first plate glass 2 which is fitted and attached to a frame. The thickness of the first sheet glass 2 is assumed to be about 10 mm or less, but it may be about 12 mm with a windproof finish for high-rise as required.

  A rectangular second glass sheet 3 smaller in size than the first glass sheet 2 is provided on the surface on one side of the first glass sheet 2, that is, the surface that becomes the indoor side. The sheet glass 3 is provided by causing the peripheries of the four sides of the first sheet glass 2 to project more than the periphery of the second sheet glass 3. In the embodiment, the second glass sheet 3 is similar to the first glass sheet 2, and the distance from the periphery of the second glass sheet 3 to the periphery of the first glass sheet 2 is the same. . The second glass sheet 3 is not provided so as to be offset to the corner portion of the first glass sheet 2. The second sheet glass 3 may be a glass with a mesh for fire protection.

  The second glass sheet 3 is provided at a predetermined distance from the first glass sheet 2. In order to maintain this distance, a frame-like spacer is provided along the periphery of the second glass sheet 3 in the peripheral area. 4 is intervened. The spacer 4 is made of hollow aluminum and has a width for maintaining a predetermined distance between at least the second glass sheet 3 and the first glass sheet 2. Furthermore, preferably, the aluminum forming the spacer 4 is preferably subjected to an antirust treatment.

  Moreover, the hygroscopic agent 5 is filled and stored in the hollow of the spacer 4 described above, and by actively removing moisture, generation of condensation that occurs on the opposing surface of the first glass sheet 2 and the second glass sheet 3 To prevent in advance.

  Further, the spacer 4 and the first glass sheet 2 and the second glass sheet 3 are airtightly fixed by polymerization with a sealing agent 6. Silicone rubber is assumed as the sealing agent 6 and this silicone rubber is excellent in heat resistance, cold resistance, oil resistance, ozone resistance, and electrical insulation, so that it is good for the environment. Can be held. Moreover, it is also possible to add a gasket if necessary.
