[Problems to be solved by the invention]
However, when the building glass brick described in Patent Document 1 is used as a component of the wall, it has daylighting properties, but even if reinforcing bars such as reinforcing bars are arranged at joints between the building glass bricks, Since the glass brick for construction is a substantially rectangular parallelepiped, the bond between the glass bricks for construction cannot be sufficiently increased, and there is a problem in terms of strength.
[0005]
An object of the present invention is to provide an architectural glass brick and a glass brick wall capable of constructing a glass brick wall having sufficient daylighting and sufficient strength.
[0006]
[Means for Solving the Problems]
The inventors of the present invention provided a concave portion on the side surface of a building glass brick having translucency, and inserted a reinforcing bar into an insertion portion formed by the adjacent building glass brick, whereby the building glass brick. The present invention is proposed by finding that a glass brick wall having translucency arranged in the vertical and horizontal directions and having sufficient strength can be constructed.
[0007]
That is, the architectural glass brick of the present invention is made of glass having a thickness of 7 mm and an average transmittance of 15 to 85% in the wavelength range of 400 to 700 nm, and has a groove on the side surface. The surface roughness Ra is 1.0 to 50.0 μm in Ra.
[0008]
Further, the glass brick wall of the present invention is made of glass having an average transmittance in the wavelength range of 400 to 700 nm of 15 to 85% with a thickness of 7 mm, and has a groove on the side surface, and the surface of the groove The glass for construction is composed of a plurality of architectural glass bricks having a surface roughness Ra of 1.0 to 50.0 μm, reinforcing bars, and fillers, and the adjacent concave portions of the architectural glass bricks. A reinforcing bar is inserted through the insertion part formed by the brick, and an uncured filler is filled in the gap between the surface of the concave portion of the glass brick for construction and the reinforcing bar, and is cured.
[0009]
[Action]
The architectural glass brick of the present invention is made of glass having an average transmittance in the wavelength range of 400 to 700 nm of 15 to 85% with a thickness of 7 mm, and has a concave portion on the side surface. Since the surface roughness Ra is 1.0 to 50.0 [mu] m, it is possible to construct a glass brick wall having sufficient lighting properties and sufficient strength. That is, since the average transmittance in the wavelength range of 400 to 700 nm is made of glass with a thickness of 7 mm and 15 to 85%, the glass block wall constructed using the architectural glass brick has sufficient daylighting, Moreover, a reinforcing bar is inserted in the insertion part formed by the glass brick for construction adjacent to the groove part located on the side surface of the glass brick for construction, and the surface roughness is 1.0 to 50.0 μm in terms of Ra. By filling a filler between the surface of the groove and the reinforcing bar, the surface of the groove is large even if it is not chemically bonded to the surface of the groove, and the surface of the groove is large. This is because the friction between the filler and the filler is increased, and the bond between the glass bricks for building can be increased, so that the strength of the glass brick wall can be increased.
[0010]
When the average transmittance in the wavelength range of 400 to 700 nm is made of glass with a thickness of 7 mm and lower than 15%, it is not possible to obtain daylighting properties, and when it is made of glass higher than 85%, Since the filler can be completely seen through, the design is impaired.
[0011]
If the surface roughness of the groove is less than 1.0 μm in Ra, the frictional force between the filler filled in the gap between the reinforcing bar and the surface of the groove and the surface of the groove becomes weak. If the strength of the glass brick wall is not sufficiently high, and Ra is larger than 50.0 μm, cracks are likely to occur upon impact, and the cracks may extend and break. In addition, the preferable range of the surface roughness of the surface of a concave part is 2.0-30.0 micrometers in Ra.
[0012]
The architectural glass brick of the present invention can support one architectural glass brick with a plurality of reinforcing bars when the concave portions are arranged at a plurality of locations on the side surface, preferably parallel to the facing surface. Therefore, the strength of the glass brick wall can be further increased, which is preferable.
[0013]
Further, the architectural glass brick of the present invention is not limited to a substantially rectangular parallelepiped, and the bottom surface may be a substantially quadrangular prism such as a trapezoid, a parallelogram, a rhombus, or a substantially triangular prism, and is a columnar shape in which the rectangular parallelepiped is curved in one direction. It may be the body.
[0014]
When the silane coupling agent is applied to the surface of the concave stripe portion, the architectural glass brick of the present invention is less susceptible to cracks due to the repair of fine scratches, and heat that fills the concave stripe portion as a filler. This is preferable because the adhesive strength with a curable resin or the like is increased. As the silane coupling agent, aminosilane, epoxy silane, ureido silane, methacryl silane, vinyl silane, styryl silane and the like can be used.
[0015]
The architectural glass brick according to the present invention is transparent when viewed from a glass containing 100 to 10 ¹² bubbles per kg, so that a person or an object can be clearly visually recognized while having daylighting properties. So-called privacy that cannot be performed is easily obtained, which is preferable. If the number of bubbles is less than 100 per kg, the above effect is difficult to obtain, and if the number of bubbles is more than 10 ¹² per kg, the average transmittance with a thickness of 7 mm in the wavelength range of 400 to 700 nm is 15%. %, And the mechanical strength tends to be impaired. In addition, a bubble refers to what has a diameter of 0.01 mm or more.
[0016]
When the glass brick for construction of the present invention is made of glass having an average coefficient of thermal expansion at 30 to 380 ° C. of 70 × 10 ⁻⁷ / ° C. or less, it is not easily damaged by cooling after the heat treatment process or by thermal shock due to severe temperature changes. .

[0017]
The glass brick wall of the present invention is made of glass having a thickness of 7 mm and an average transmittance of 15 to 85% in the wavelength range of 400 to 700 nm, and has a concave portion on the side surface, and the surface of the surface of the concave portion. It consists of a plurality of architectural glass bricks having a roughness Ra of 1.0 to 50.0 μm, reinforcing bars, and fillers, and the concave portions of the architectural glass bricks and the adjacent architectural glass bricks Reinforcing bars are inserted into the formed insertion part, and the gap between the surface of the concave part of the glass brick for construction and the reinforcing bar is filled with an uncured filler and cured, so that it has sufficient daylighting In addition, it has sufficient strength. That is, since the architectural glass brick is made of glass having a thickness of 7 mm and a thickness of 15 to 85% in the wavelength range of 400 to 700 nm, it has sufficient translucency, and a reinforcing bar is inserted through the insertion portion. Unfilled filler is filled in the gap between the surface of the groove and the reinforcing bar, and the surface of the groove has an appropriate roughness of Ra of 1.0 to 50.0 μm by Ra. This is because a large frictional force acts between the building glass brick and the filler, and the bonding between the building glass bricks can be enhanced, so that the strength of the glass brick wall can be increased. Therefore, the glass brick wall of the present invention can be used as, for example, a decorative wall that can extract light from a partition wall or illumination as scattered light.
[0018]
As the reinforcing bars, reinforcing bars, stainless bars, FRP rods, connecting pipes, and the like can be used. In particular, the FRP rods are preferable because they are transparent and hardly noticeable.
[0019]
An optical fiber, a light-emitting diode, a fluorescent lamp, or the like is inserted into the gap between the surface of the concave portion of the glass brick for construction and the reinforcing bar, or an optical fiber in a hollow part of a transparent reinforcing bar such as a cylindrical FRP rod. It is preferable to insert a light-emitting diode, a fluorescent lamp, or the like because light can be emitted from the inside of the glass brick wall.
[0020]
As the filler, mortar or curable resin can be used, and the curable resin is preferably a highly transparent resin such as an epoxy resin, an unsaturated polyester resin, or a silicone resin. In particular, the silicone resin has elasticity. It is more preferable because it has excellent weather resistance.
[0021]
The glass brick wall of the present invention is preferably formed by forming a sealing layer on the inner surface of the housing, since the housing and the building glass brick are not in direct contact and are excellent in airtightness.
[0022]
Moreover, since the glass brick wall of this invention will not contact between building glass bricks, when the buffer material which consists of an elastic body is arrange | positioned between the glass bricks for construction.
[0023]
As the buffer material made of an elastic body, silicone rubber, EPDM rubber, and chloroprene rubber are preferable because of excellent weather resistance.
