Description of the Related Art A glass block is formed by fusing and integrating a pair of glass moldings having a box shape with a bottom and no lid at the open edges of each other, and provides sound insulation, weather resistance, and light transmission. Since it is a building material having excellent properties, it is widely used as an exterior material or interior material of a building or a veranda.

工法が開発されている。[0003] In general, glass blocks are constructed by stacking glass blocks one by one at a building site and bonding each glass block with a mortar to form a panel. In order to simplify the process, a so-called panel construction method has been developed in which a glass block panel in which a plurality of glass blocks are fixed with a mortar in an outer frame is manufactured in a factory in advance, and this is incorporated into an opening of a building. .

断熱性能を有している。By the way, in recent years, a multi-layer glass panel in which two panes of glass are attached to a sash at a constant interval is becoming popular. Due to the air layer, it has very good thermal insulation performance.
【０００５】また上記のような方法で作製されるガラス

た場合と比べると、外気温と室内温度の差が大きい夏期
や冬期に冷房や暖房を効率的に行えず、不経済である。[0005] The glass block panel manufactured by the above method also has a certain heat insulating performance. However, when this glass block panel is used as an exterior material, compared with the case of using a multi-layer glass panel, Cooling and heating cannot be performed efficiently in summer or winter when the difference between the outside temperature and the indoor temperature is large, which is uneconomical.

冷やしたり、暖めることが困難である。That is, even if the room is cooled in summer,
The heat of the outside air is easily transmitted through the glass block panel to raise the indoor temperature.On the contrary, even if the room is heated in winter, the heat inside the room is transmitted to the outside through the glass block panel and escapes to the outside air. It is difficult to cool or warm the room efficiently.
【０００７】本発明は、上記事情に鑑みなされたもので

とを目的とするものである。The present invention has been made in view of the above circumstances, and an object of the present invention is to provide a method of manufacturing a glass block capable of further improving the heat insulating performance of a glass block panel.

提案するに到った。The inventor of the present invention has conducted various experiments to achieve the above-mentioned object. As a result, the reason why the heat insulating performance of the glass block panel is lowered is that the glass block panel has an inflow from one surface. It has been found that most of the heat generated is conducted through the side surface of the glass block and dissipated from the other panel surface, and the present invention has been proposed.

げることを特徴とする。That is, according to the method of manufacturing a glass block of the present invention, the open edges of a pair of glass moldings each having a box shape with a bottom and no lid are joined and integrated via a rubber joining member. It is characterized in that air is evacuated from a part of the member to lower the internal pressure.

優れた断熱性能を有するガラスブロックパネルを得るこ
とが可能である。In the glass block manufactured by the method of the present invention, the open edges of a pair of glass moldings are joined and integrated via a rubber joining member having low thermal conductivity. Even if heat flows in from the surface,
Heat conduction is cut off by the coupling member, so that it is hardly transmitted to the other surface. Therefore, by using this glass block, it is possible to obtain a glass block panel having extremely excellent heat insulating performance.

ａｔｍ程度とすることが望ましい。Further, since the inside pressure of the glass block is reduced by bleeding air from a part of the connecting member, dew condensation hardly occurs inside the glass block, and the appearance quality is not impaired by mold or the like. The internal pressure of the glass block is set at 0.6 in consideration of the expansion of the internal air and the sealing performance of the rubber binder.
It is desirable to be about atm.

も良い。As the material of the connecting member used in the present invention, ethylene propylene rubber, silicon rubber, chloroprene rubber, urethane rubber, etc., which are excellent in weather resistance, are suitable. Also, after the air bleeding portion of the coupling member is pierced with a needle for forming an air hole, the air hole is closed by a pressure difference between the inside and outside of the glass block, and after reaching a predetermined pressure. The air holes are sealed using a sealing material of the same material as the joining member or an adhesive compatible with the joining member. The portion of the coupling member where the air hole is formed may be inwardly bulged in order to lengthen the air vent hole and reliably prevent air leakage.

に結合することが可能となる。Therefore, the connecting member of the present invention may be formed in such a form that the internal pressure of the glass block is reduced and then the pair is adhered to the open edges of the pair of glass molded bodies so that the two can be firmly connected. For example, a member formed with a concave portion for fitting an open edge of a glass molded body, or a coupling member provided with a small protrusion on a side surface of the concave portion can be used. Further, by using an adhesive together or by thermally processing the open edge of the glass molded body to increase the thickness of the front end portion, the glass molded body can be more firmly bonded.

射層や熱伝導遮断層を形成することが好ましい。In the case where a plurality of glass blocks are formed into a panel using a mortar, when heat flows from one surface of the glass block, heat is easily transmitted to the other surface via the mortar. Instead, it is preferable to use a lightweight mortar, a rubber joint material or a resin joint material having a small thermal conductivity, or to form a heat radiation reflection layer or a heat conduction blocking layer between the glass block and the mortar.

て塞がれるため、内部気圧が変化することはない。A part of the rubber connecting member is processed into a form suitable for air bleeding. After the glass molded body is bonded and integrated as described above, air is pierced by piercing the needle of the air bleeding tool. By removing, the internal pressure was set to 0.6 atm. Incidentally, since the air hole formed by piercing the air release rubber with a needle is closed by the pressure difference between the inside and outside of the glass block, the internal pressure does not change.

A stress absorbing layer (thickness: 500 μm) was formed by placing the device in a press for 2 minutes.

The joining members 12 are disposed on the open edges 11a, 11a of the glass block 10 and the internal pressure of the glass block 10 is low. Therefore, the joining members 12 are sucked toward the glass block 10, and the respective glass molded bodies 11, 11 Are combined and integrated.
An air vent hole 12a is formed in a part of the coupling member 12, and is sealed with a sealing material 13 made of silicone rubber.
