Description

[Detailed Description of the Invention] (a) Field of the Invention The present invention comprises a multi-layer transparent plate whose space is filled with an insulating gas having a higher specific gravity than air, and a metal frame surrounding the peripheral edge of the multi-layer transparent plate. Regarding transparent structures, it is applied to doors and windows of houses, warehouses, refrigerators, and low-temperature showcases.

(B) Background Art and Problems Thereof A multilayer transparent plate includes at least two transparent plates maintained at a predetermined distance, and a frame interposed at the periphery of the transparent plates to hold the pre-distributed bacteria. It is constructed by airtightly joining other members, and its use is rapidly expanding because it has good heat insulation and is resistant to condensation.

In addition, for the purpose of increasing the heat insulation properties of the multilayer transparent plate or increasing the sound insulation properties, it is possible to fill the internal space with an insulating gas consisting of a gas with a lower thermal conductivity than air or a gas with a higher specific gravity than air. Layered transparent plates are now on sale.

These multi-layer transparent plates either evacuate the air in the space and supply insulating gas, or after the gas supply process in which air is exhausted along with the supply of insulating gas, the passages are blocked with camps.
If the sealing provided by the cap was insufficient, gas would gradually leak from the passage, resulting in a reduction in the insulation effect.

(c) Purpose of the Invention The object of the present invention is to prevent the leakage of the insulating gas from the passage after the space is filled with the insulating gas.

B) Overview of the Invention At least two transparent plates facing each other with a gap therebetween; at least one frame member interposed between peripheral edges of opposing surfaces of the transparent plates; and the transparent plate and the frame. A multilayer structure consisting of an adhesive that interconnects members, at least one layer of space defined by the connection of the transparent plate and frame member, and an insulating gas having a higher specific gravity than air that is inserted into this space. In the transparent plate, at least one passage is formed on the frame side for communicating the space with the outside and supplying insulating gas to the space, and the passage is closed with an elastic cap that can be suppressed and deformed. A transparent structure in which a metal frame surrounding the peripheral edge of a multilayer transparent plate is provided, and the cap is compressed and deformed by the metal frame.

(The force (7') is an elastic cap made of rubber or the like capable of suppressing deformation, and is fitted into the removed part on the sealing part side (7), and the adhesive applied to the surface is applied to the spacer (4A) and the sealing part side. (05) is a metal frame having a U-shaped cross section, and is attached to the metal frame (12h) (12b) to close the passage (12h) (12b) and keep the space (5) sealed. The elastic cap (7') is fitted into the end edge and deformed by pressing as shown in FIG.
), the periphery of one end expands in the direction of the periphery and becomes flat.

i? ! I rj,: The first layer transparent plate (1) is manufactured by the manufacturing method below. Each spacer (4A, ) (4BX4CX4r)) is connected to each other by each corner connector (12AX12BXi2CX12D)]~te frame After assembling the frame side (3), apply adhesive (6A) made of double-sided adhesive tape to the entire circumference of both sides of this frame side.
(6J3), and then as shown in Fig. 5, a rectangular board 0η and eight guides (], 8A) to (], 811) erected on the outer circumferential surface of this board. Assembly jig (
16), transparent plate (2A), frame member (3), transparent plate (2B
) and then press the transparent plate (2B) to attach both transparent plates (2A) (2B) and the frame member (3) to the adhesive (6A).
) (6B) to form a space (5). Next, a resin-based sealant such as thiocol is applied to the annular groove formed by the inner peripheral end surfaces of both transparent plates and the outer surface of the frame member, except for the passages (12h) (12h) of the frame member (3). The passage (1
2h) (12h) A semi-finished product is obtained in which the space (5) is kept airtight except for around 12h.

Next, a plurality of semi-finished products are erected so that both passages (12h) (12h) are located at the top of the frame member (3), and the supply nozzle (1a) of the gas supply machine is connected to the corner connector (12A). ) through the passage (12h), and the tip of this supply nozzle is placed at a height of 1N at the bottom of the space (5) as shown in FIG. With the injection of insulating gas ((l), which has a higher specific gravity than air, 1.(g) space (5
