Description

[Detailed description of the invention] This invention incorporates resin glass with particularly high heat resistance into two double-glazed glasses, creating a three-layer structure with two inorganic glasses and one resin glass, which improves heat insulation performance. It provides double-glazed glass that is easy to work with, has improved moisture-proofing and sound-proofing effects, and is easy to work with due to the elasticity and flexibility of the long channels.

Normally, double-glazed glass is made by placing two or more pieces of glass side by side at appropriate intervals, filling the gap with dry gas and sealing the surrounding area. It is designed to increase the thermal resistance of the

In this case, the thermal resistance increases as the number of gas layers increases from one layer to two layers, and from two layers to three layers.

However, increasing the air layer also increases the number of glass sheets, which increases the weight and thickness, which poses a practical problem.

In addition, resin glass has a high vapor permeability, and if it is attached to the outside of double-glazed glass or is in direct contact with the outside air, it is difficult to maintain the temperature and dryness of the air layer for a long period of time.

Therefore, in this proposal, we take advantage of the property that thermal resistance increases when one air layer is divided into two, and we install resin glass, especially thermosetting material, between the two double-glazed windows, which has heat ray reflective properties. A channel (spacer) is processed to sandwich a phenol-based, urea-based, or epoxy-based resin board, or a hard polyvinyl chloride (PVC) resin board in the case of thermoplastic resin, and an attachment is installed to form a three-layer glass panel. Formed.

As a result, in addition to the increased resistance of the air layer divided into two layers, the heat ray reflection properties of the resin glass are added, resulting in significantly improved heat insulation performance compared to ordinary multilayer glass, and increased moisture and soundproofing effects. Can be done.

Furthermore, this proposal takes into account expansion and contraction due to temperature by assembling resin glass using a grooved channel as a frame and gluing the glass to the periphery of both sides.

Next, the structure of this invention will be explained using a rectangular glass structure.

Polygonal products are also processed in the same way as this rectangular product.

First, a rectangular frame 24 is made using four channels 1.

The channel 1 is mainly made of a band-shaped metal plate, and has a hollow trapezoidal cross section, and as shown in FIG. The rising portions 25° and 25' of the sides are bent inward at right angles to form thousand sides 4 and 4', and the edges 5 and 5' of the thousand sides are formed with concave faces facing each other and concave from both sides. A long groove 6 is formed in the center of the concave portion 7, and the interior 10 is hollow.

As shown in FIG. 3, the end 1 of the channel 1 having such a structure is finished at right angles to the longitudinal direction with the long groove 6 facing inward.
6. Align the edges of the 16s at right angles, insert the right-angled key-shaped attachment 17 into it, and insert the inner 10° 10.
The book channels are connected to form a rectangular frame 24.

If implemented, a moisture absorbent or desiccant agent 23, such as silica gel or calcium chloride, is contained within the channel.

Then, the resin glass 18 is incorporated into the recessed part 7 formed by the recess inside the frame, and the outer surfaces of both sides of the frame 24,
That is, the inorganic glass 19.20 is placed on the outer side of the rising portions 25.25' on both sides of the channel 1, and the sloped sides 3, 3' of the channel 1 and the end edges 19', 20' of the inorganic glass 19.20 are combined. The gap part 21 and flat part 2 formed by
The adhesive 22 is poured onto the surface and hardened to form the double-glazed glass of the present invention.

As mentioned above, this project consists of a trapezoidal cross-section with sloped sides on both sides, and is assembled into a rectangular or polygonal shape with the long side facing inward and the short side facing outward. Since the inclined side edge and the glass surface are firmly bonded with the adhesive 22, the inside is airtight, and the heat rays are reflected by the heat-resistant resin glass 18, so the heat insulation performance is high. Since it is divided into two wheels by glass, the resistance of the air layer increases, and the insulation effect is even greater, making it suitable for soundproofing, moistureproofing, and cold protection.

Further, since the long groove 6 is provided in the center in the longitudinal direction, flexibility in opening and closing is possible, and the elasticity is also increased, so it is easy to assemble according to the thickness of the resin glass 18, and it is convenient to take the moisture proofing agent 23 in and out.

Furthermore, in addition to the above-mentioned effect, the long grooves 6 act as a buffer zone for expansion and contraction due to temperature, and at the time of construction, they ease the pressure exertion and provide safety.

In particular, since the moisture absorbent 23 in the channel sucks the moisture inside the double-glazed glass through the long groove, the entire interior is always in a dry state, so there is no risk of cloud formation even if there is a change in the outside air.
