JP2007015908A - Free-cutting, double-glazed vacuum glass - Google Patents

Abstract

<P>PROBLEM TO BE SOLVED: To provide a retrofittable, free-cutting, double-glazed vacuum glass for shutting out a noise from the outside such as a road, insulating an air-conditioned room from outside heat and preventing the dew condensation on a window glass. <P>SOLUTION: The retrofittable, free-cutting, double-glazed vacuum glass has a sound/heat-insulating function and prevents dew condensation without deteriorating its appearance or architectural design flexibility. The glass sheet adopts a dual structure in which a single-layer part and a multilayer part are integrated, a gap part is depressurized and evacuated, and the periphery of the single-layer glass sheet serves as margins for measurement and cutting. The glass may be armed or frosted to fit various applications. This enables retrofitting of sound-insulating, heat-insulating, dew-condensation-preventing double-glazed glass in existing windows that could not be remade into double-glazed windows, due to restrictions of violation of joint-ownership spaces in conventional apartments. <P>COPYRIGHT: (C)2007,JPO&INPIT

Description

  The present invention has two layers at the center of the plate glass for the purpose of giving the window glass a heat insulating effect, a sound insulating effect and a non-condensing property, and having a cuttable surface so that it can be freely fitted to the window frame. The structure relates to a freely cut vacuum double glass in which the peripheral portion is a single layer and the two-layer portion is evacuated.

  Conventionally, there has been a double glass window in which a window frame is combined and a void is decompressed. Moreover, although there existed what was made into the multilayer glass and the space | gap part was made into the vacuum, there existed a fault which cannot be cut | disconnected in a free shape.

Therefore, there are the following problems.
In order to have the effect of heat insulation, sound insulation and dew condensation on the window, a double window frame with a vacuum in the gap portion takes extra space, deprives the freedom of architectural design, Maintenance was required, and it was not possible to retrofit in condominiums due to infringement problems in common areas.
Moreover, since the conventional multilayer vacuum glass cannot be cut freely, it has to be pre-processed exclusively for the size of the sash frame of the part to be used, which has been forced to be expensive.
The present invention is intended to solve the above problems.

  If it is a double-layer / single-layer monolithic plate glass with a vacuum in the gap, the existing glass window can be retrofitted to the double-glazed window easily after measuring and cutting according to the target window frame at the construction site, and sharing the apartment Partial infringement problems do not occur. It is the freely cut vacuum double glass characterized by the above.

  The present invention allows an existing ordinary window sash glass to be retrofitted to a vacuum double glass simply by replacing the glass without infringing on a common part in an apartment or the like. It is glass. Therefore, there is no need to remodel the window frame, to make a special glass at the manufacturer's factory, and to attach a special jig for remodeling to the double window glass. Further, since the vacuum layer is glass-sealed, maintenance work such as seal replacement for vacuum holding and evacuation is unnecessary, and the vacuum holding performance can be greatly improved.

Embodiments of the present invention will be described below.
(A) A rib glass (3) having a different melting point and a spacer rod glass (4) for maintaining a glass strength during vacuum are arranged at regular intervals on a base plate glass (1) to be a sash fitting portion.
(B) Cover the rib glass (3) with the top glass (2) having the same melting point as the base glass (1) having the same size as the rib glass (3).
(C) A sealing hole (6) is previously provided in one place on a flat surface in the top glass.
(D) It is exposed to an ambient temperature exceeding the melting point of the rib glass (3) and the spacer rod glass (4), and bonded to the base plate glass (1) and the top plate glass (2) to form a two-layer / single-layer integrated structure.
(E) Depressurization from the mouth of the sealing hole (6), the two-layer gap (5) is evacuated, and the sealing hole (6) is sealed with a vacuum.
(F) The single layer portion of the base plate glass (1) forms a cuttable portion (7).
The present invention has the above configuration.
By cutting, fitting, and using the present invention in the size of a standard window sash (8), it is possible to convert external noise into a window that can insulate external noise, suppress heat dissipation, and hardly condense. It becomes.
Instead of evacuating the two-layer gap (5) of the present invention, air can be substituted with a rare gas or the like. In this case, the spacer rod glass (4) can be deleted.

Claims (1)

  A rib glass frame smaller than the base plate glass is provided on the base plate glass, spacer glass rods are arranged on the base plate glass at regular intervals in the rib glass frame, and a top plate glass having the same size as the outer periphery of the rib glass is placed to form a one-piece double glass structure. A free-cutting vacuum double glass characterized in that a vacuum double glass capable of freely cutting the periphery of the base plate glass is obtained by applying a vacuum to the double glass gap through an opening provided in the top plate glass.
