性にも優れている。Glass blocks are used to enhance the decorativeness of buildings by making them continuous with putty for inset windows, partitions, or ceilings, and to bring in external light such as sunlight. What's more, this glass ivy has a reduced pressure inside and is hollow, providing excellent sound insulation and fire retardant properties.

目的としている。However, conventional glass blocks have high transmittance not only for visible light, which is necessary for indoor lighting, but also for infrared rays (heat rays), so on sunny days, even if the room is bright, the indoor temperature may rise. However, it has the disadvantage of causing discomfort to the people in the room. Therefore, in recent years, efforts have been made to prevent infrared rays from transmitting as much as possible by coating the surface of the glass block with paint containing an infrared absorbing agent or pasting a resin sheet containing an infrared absorbing agent. However, with the former method, it may not be possible to absorb the desired amount of infrared rays, and since the paint is sprayed onto the surface of the glass blocks after they are assembled, work must be done to prevent the paint from getting on parts other than the blocks. On the other hand, the latter method has problems such as being extremely expensive. In view of these circumstances, it is an object of the present invention to provide a glass block that allows a desired amount of visible light to pass through, prevents a desired amount of infrared rays from passing through, and can reduce manufacturing costs.

とが好ましい。In order to achieve such an object, the present invention has a metal thin film layer laminated on at least one side surface of the glass block body, which transmits a desired amount of visible light and prevents a desired amount of infrared rays from transmitting. The main focus is on glass blocks. Further, it is preferable to cover the surface of the metal thin film layer with a weather-resistant resin.

Furthermore, if the metal thin film layer is covered with a weather-resistant resin, the metal thin film will not be directly exposed to outside air or rain.

い。Hereinafter, the present invention will be explained in detail with reference to the drawings showing embodiments thereof. FIG. 1 shows a cross section of an embodiment of the glass block according to the present invention when viewed from the side. As shown in the figure, in this glass block 1, a metal thin film N3 is laminated on one side of the glass block main body 2, and this metal thin film layer 3 is hidden from the external atmosphere by a weather-resistant resin layer 4. The glass block main body 2 may be similar to a conventional glass block. The metal forming the metal thin film layer 3 is not particularly limited, but silver is particularly preferred since it has an excellent infrared absorption effect. When one barb is used, its thickness is 0.1 to 0.
．． The thickness is preferably about 5 μm. Note that the metal thin film can be formed relatively inexpensively by a known method such as a wet plating method or a PVD method. The weather-resistant resin layer 4 is provided to protect the metal thin film layer 3 when it is not weather-resistant so that infrared rays do not always pass therethrough. The resin forming the weather-resistant resin N4 is not particularly limited as long as it is substantially transparent and has excellent weather resistance, but examples thereof include fluororesin paints, epoxy-modified paints, and the like. Also, its thickness is 10
The thickness is preferably about 100 μm. Note that this glass block 1 may have the metal thin film layer 3 side facing either indoors or outdoors, but it is preferable to face the indoor side. Next, the thickness of 10 m used for conventional glass blocks.
We measured the transmittance of light in each wavelength range of a glass plate with a silver thin film layer of 0.1 μm thick on a glass substrate of The results are shown in the graph of Figure 2 together with the measurement results of a glass plate whose surface was coated with a paint containing an infrared absorber (thermal infrared shielding paint made by Chugoku Paint Co., Ltd.). In the figure, the solid line represents a glass substrate provided with a silver thin film layer, the dashed line represents a glass substrate only, and the broken line represents a glass substrate coated with a commercially available paint containing an infrared absorber. As shown in the figure, a glass substrate with a thin silver film layer has a transmittance of 20 to 45% in the visible light range.
In the infrared region, the transmittance is only 20% or less, and visible light in external light such as sunlight brightens the room.
It can be seen that the indoor temperature does not rise. On the other hand, in the case of a glass substrate coated with a commercially available paint containing an infrared absorber, the transmittance is lower than that of a glass substrate alone in both the visible light YA region and the infrared region, but the transmittance in the infrared region is still over 60%. It turns out that he is unable to fully achieve his goals. The invention is not limited to the above embodiments. In the above embodiment, the metal thin film layer was laminated on one side of the glass block body, but it may be laminated on both sides.

持させることができる。As described above, the glass block according to the present invention has a metal thin film layer laminated on at least one side surface of the glass block body, which transmits a desired amount of visible light and prevents a desired amount of infrared rays from transmitting. Visible light necessary for illumination is transmitted indoors, but infrared rays that increase indoor temperature can be prevented from penetrating indoors. Therefore, the room can be brightened by sunlight and made comfortable without being hot. Moreover, it can be provided at low cost. Furthermore, by covering the surface of the metal thin film layer with a weather-resistant resin, the metal thin film is not directly exposed to outside air or rain. Therefore, the infrared ray blocking effect of the metal thin film can be maintained indefinitely.
