ものが最適である。 In the present invention, as a sealing plug 6 for sealing the gas injection hole, or the gas injection hole and the gas exhaust hole, a plug enlarged head 7 that is larger than the gas injection hole or the gas exhaust hole to be inserted, and a hole insertion hole are provided. part 8 and a pawl part 9 provided on the side of the plug enlarged head 7 around the hole insertion part 8, and the plug enlarged head 7 and the pawl part 9 form a groove shape, and the plug A groove-shaped portion between the enlarged head 7 and the claw portion 9 is filled with a sealing material 10,
It can be set simply by pushing it into the hole, and it has a structure that prevents it from coming out easily after it is set. The plug enlarged head 7 of this sealing plug 6 is made larger in size than the hole into which it is inserted so that when it is pushed into the gas injection hole, or the gas injection hole and the gas discharge hole, it closes the hole. In addition, the hole insertion part 8 can be inserted into the gas injection hole or the gas discharge hole, and the hole insertion part 8 is designed so that there is no gap between the spacer and the hole insertion part and the sealing plug is easily fixed in the hole. It is preferable to have the same size as or almost the same size as the hole, but it may of course be smaller than the hole. Further, the length of the hole insertion portion 8 is determined to be an appropriate length, but in the case of a tubular spacer with a hollow interior, the length of the sealing plug 6 should be at least long enough to penetrate the spacer. It is particularly preferred for retention within the spacer. Moreover, a groove-like part is formed between the claw part 9 of the sealing plug 6 and the enlarged part of the plug, and the groove-like part forms a locking part of the sealing plug 6 of the gas injection hole or the gas discharge hole of the spacer, i.e. In the case of a tubular spacer, the sealing plug is held by holding the locking part provided around the hole drilled on the outer surface of the spacer, or in the case of a rod-shaped spacer, the locking part provided inside the hole of the spacer. 6 is provided on the enlarged head side of the plug around the hole insertion part so that it can be fixed in the gas injection hole or the gas discharge hole. In particular, this pawl portion 9 has its tip facing toward the enlarged head of the plug so that it is easy to push the sealing plug into the gas injection hole or gas discharge hole, and it is difficult to pull out after being pushed in and set. It is preferable to make it protrude.
The material for such a sealing plug may be selected from plastic, metal, ceramic, etc., but it is particularly suitable to be made of elastic rubber or plastic that deforms to some extent.

どが挙げられる。 The groove-like part between the enlarged head 7 and the claw part 9 of the sealing plug 6 can be simply pushed into the gas injection hole or the gas discharge hole to seal the gap between the hole and the sealing plug. A sealing material 10 is provided before the sealing plug is inserted into the gas injection hole or the gas discharge hole so that the gas injection hole or the gas discharge hole is inserted.
As such a sealing material, a material with low gas permeability and moisture permeability, strong bonding strength with the spacer and sealing plug, and high physical and chemical durability is selected, such as polyisobutylene sealant, Representative examples include silicone sealants, polysulfide sealants (Thiocol), polyurethane sealants, and butyl rubber sealants, as well as acrylic resin sealants, polybutadiene sealants, and polybutadiene-polystyrene sealants. .

４の周囲の外側部分に設けた例である。 4 to 9 are drawings showing a typical sealing plug according to the present invention and a state in which the sealing plug is inserted into a gas injection hole or a gas discharge hole of a spacer. The sealing plug 6 shown in FIGS. 4 and 5 is a typical example for sealing the gas injection hole 4 of the tubular spacer 2, and the plug enlarged head 7 is larger than the hole diameter of the gas injection hole 4.
The tip of the plug is enlarged so that a groove-like part is formed by a hole insertion part 8 having approximately the same length as the hole diameter of the gas injection hole 4 and the end of the plug enlarged head 7 around the hole insertion part 8. It has a claw portion 9 that protrudes in the direction of the head 7,
In addition, before insertion into the gas injection hole 4, a sealing material 10 is provided in advance in the groove-shaped portion between the enlarged head 7 and the claw portion 9, and the sealing material 10 is inserted into the spacer 2. FIG. 5 shows a cross section of the gas injection hole 4 when it is pushed into the gas injection hole 4 and set. Further, the sealing plug 6 shown in FIGS. 6 and 7 is a typical example for sealing the gas injection hole 4 formed in the corner joint portion 2 of the spacer, and the sealing plug 6 shown in FIG. Almost the same as the sealing plug 6, the plug is provided with a plug enlarged head 7, a plug insertion part 8, a pawl part 9, and a sealing material 10, and the sealing plug 6 is connected to the gas at the corner joint part 2 of the spacer. FIG. 7 shows a cross-section of the state in which it is pushed into the injection hole 4 and set. Further, the sealing plug 6 shown in FIGS. 8 and 9 is another example for sealing the gas injection hole 4 made in the rod-shaped spacer 2 or the corner joint part 2 of the spacer, and the shape is different. Basically, it is provided with a plug enlarged head 9, a plug insertion part 8, a pawl part 9, and a sealing material in the same way as the sealing plug 6 shown in FIG. The structure of the gas injection hole portion of the spacer shown in FIG. 9 is such that when the sealing plug 6 is inserted and set into the gas injection hole 4 of the spacer, the enlarged head of the sealing plug 6 is inserted from the outer surface of the spacer 2. This is an example in which the embedded part 13 of the plug enlarged head 9 is provided in the outer part of the spacer 2 around the gas injection hole 4 so that the outer surface of the spacer 2 is flat without the part 7 protruding.

録請求第１項記載の複層ガラス。[Scope of Claim for Utility Model Registration] (1) A spacer having at least one gas injection hole, or a gas injection hole and a gas discharge hole, arranged along the periphery of a plurality of glass plates. In double glazing, a hollow layer is formed between a plurality of glass plates which are spaced apart in parallel, and gas is injected into this hollow layer through the gas injection hole, through the gas injection hole to be inserted or the gas discharge hole. It has a large plug enlarged head, a hole insertion part, and a pawl provided on the side of the plug enlarged head around the hole insertion part, and a groove is formed between the plug enlarged head and the pawl. A sealing plug whose groove-shaped part between the plug enlarged head and the claw part is filled with a sealing material is inserted into the gas injection hole or the gas injection hole and the gas injection hole from the hole insertion part side of the sealing plug. A double-glazed glass panel characterized in that the gas injection hole or the gas injection hole and the gas exhaust hole of the spacer are plugged by inserting the gas into the gas exhaust hole and using the enlarged head of the plug, the pawl, and the sealing material. (2) The double-glazed glass according to claim 1, wherein the tip of the claw of the sealing stopper projects toward the enlarged head of the stopper.
