Abstract

PURPOSE:To carry out rapidly and easily the assembling work of a frame member by using one of two paths formed in corner connectors as a path for feeding a heat insulating gas and by exhausting air in a space from the other. CONSTITUTION:Double-coated adhesive tapes 6A, 6B are stuck to the whole peripheries of both sides of a frame member 3 assembled by inserting both legs 12l, 12m of corner connectors 12A-12D into the hollows 9 of spacers 4A-4D. A transparent plate 2A, the member 3 and a transparent plate 2B are successively mounted on an assembling jig 16 consisting of a substrate 17 and guides 18A-18H, and they are connected by pressing to form a space. A sealant 7 is filled into grooves formed with the internal edges of the plates 2A, 2B and the outside of the member 3 up to the height of a tube 12s on a base 12n of the member 3 to adhere the member 3 to the plates 2A, 2B. A thin part 12t covering the tube 12s is broken so as to allow the space to communicate with the outside through the tube 12s ans a path 12h, the member 3 is uprighted with the connector 12A upward, and a heat insulating gas is fed into the space from one of paths 12h. Air in the space is exhausted from the other of the paths 12h.

Description

Detailed Description of the Invention (a) Field of the Invention The present invention relates to a method for manufacturing a multi-layer transparent plate (in which a space is filled with an insulating gas having a specific gravity higher than that of air), and is mainly used for manufacturing frozen rocks such as refrigerators and low-temperature showcases. This article relates to a method for manufacturing small-layer transparent plates used for windows and doors of vessels.

(Explanation) Background: The applicant of the present invention previously filed a patent application with Sho. 5 7 - 2 0 4
8. An application was filed for a method for manufacturing a 1-inch multilayer transparent plate. Part 1 below
Referring to Figures 8 to 8, an example of the background art will be explained. (1) shown in Figures 1 and 2 is used for refrigerators, refrigeration equipment such as freezers or refrigerated showcases, and general houses. A multilayer transparent board used for windows and doors, consisting of two rectangular glass transparent boards (2A) (213).

(8l) is a granular desiccant filled in multiple layers in each of the spacers, and is made of, for example, a mixture of quick-drying silica gel that absorbs moisture and molecular sieve that dries slowly and that absorbs moisture slowly. be.

Each of the spacers is formed by extruding aluminum or the like or by bending a thin metal plate to form a hollow portion (9) as shown in FIG.
It is formed into a rectangular cylindrical shape with a hollow part (9) and a space (
Each spacer (4A) has a circular opening (il) at both ends of both the inner and outer surfaces thereof corresponding to the through-hole of the connecting tool described later. ．．

(4D), one of the adjacent and orthogonal hollow parts (0) has the negative leg (12/!), and the other leg has the other leg (.1.
The frame member (3) is assembled by connecting the respective spacers to each other by inserting the spacers (2 m). As shown in the 4th and 5th 1', the above-mentioned legs are < spacer (4△) (4I1
) is formed into a shape that can impart elasticity, such as a wave shape that is deformed under pressure within the hollow part (9) in the connected state. (
13A) (I3 port) has two connectors (12A) (t2

(12 e) When inserted into the spacing f-(4A) and stacked on both ends of this spacer, both openings (.1-1-A)
(1113) both communicate between the inside and outside of interval A (4A)).

Next, a method for manufacturing the multilayer transparent plate (1) will be explained.

First, attach the connecting tool (12
C), the spacer (4 [1
) (41)) in an L-shape, fill the hollow part (9) of each spacer with desiccant (8), and then connect the spacer (4A) with the connecting tool (1.2B). (4B), the spacer (4C) (41)) is connected using the connector (121)) to assemble the frame member (3), and the spacer (4A
) double opening (11 tA) (11 i3) and connecting tool (
12. A. ) (12f3) through hole (13A) (13
B to form two passages). At this time, each connector serves as a stopper to prevent leakage of the desiccant (8) from the hollow portion (9). Assembling the frame member, glue the adhesive (6A) (61-ri) on the opposing surfaces of each spacer (4A.) (4B) (4CX old), excluding the inner and outer surfaces, and then apply this adhesive. A frame member (3) and both transparent plates (2
A) (2B) are connected to each other, and air opening (5)
to obtain a semi-finished product. After the space 5) is formed, the semi-finished product is erected with the spacer (4A) at the top, as shown in FIG. 7, and fixed with a suitable jig.

After that, as shown in FIG. Ji conversion (+:3B
), l/, () is inserted into the space (5) through one of the passages so that its tip is located in the lower part of the space (5), and the perforated outside in the space (5) is inserted into the space (5). Exhaust nostle (L) consisting of a long and thin pipe leading to the opening (IIA) and the through hole (1:3Δ) / (A) The other passage meets the space (

As this insulating gas is supplied, the air in the space (5) is pushed upwards and flows out from the nozzle (15). ) Take out the external Jl as shown by the arrow.

1) (+2C) (+211) and Oll both transparent plates (2
A) The desired multilayer transparent plate (1) can be obtained by adhering it to (211) and maintaining airtightness between the space (!I) and the outside.

(・→Problems in the background technology ly view technology (The manufacturing method according to R is an insulating gas supply path or ventilation path 4) Two passages are installed in the through hole of the corner connector and on both the inside and outside of the spacer. Since the formed double opening [-1] requires drilling work for both openings in addition to the drilling work for the through hole, the fabrication process before assembling the frame member increases. The supply nozzle and exhaust nozzle cannot be inserted unless the openings are adjusted, resulting in the disadvantage that it takes time to correct the openings.Furthermore, when a sealing member is provided on the outer periphery of the frame, the passage is closed. Since the part of the old seal part gets into the passage, there is a disadvantage that the old part of the seal part must be removed before the K insulating gas is supplied.

(・') The object of the present invention is to simplify the work of introducing the frame part, and also to prevent the seal part from entering the passage before supplying the insulating gas, and to seal the passage after supplying the insulating gas. What I did to make it easy to do.

Outline of the present invention i' A base portion of the spacer that is not inserted into the hollow portion between the legs;
In a part of this base, there are two adjacent filter thin film parts with thin walls, and two passages σ) are formed (one side is closed by these thin film parts) (l, 1 - · corners). After constructing a frame member using a connecting tool 1 and pasting a sealing member around the outer surface of this frame member, a part of the sealing member located on the outside of both thin film parts is removed, and both thin film parts are removed. After connecting the space and the outside through the broken passage and inserting the corner connector at the top 11' of the frame member, insert an insulating hole into the space from one passage, and connect the other passage to the outside. A method for manufacturing a multi-layer transparent plate that exhausts air in a space to the outside.
