Description

  The present invention relates to an architectural decorative brick that can be used for an exterior material, an interior material, and a decorative material of a building, a manufacturing method thereof, and an architectural decorative brick wall surface structure.

  In recent years, translucent architectural glass bricks have been used on the wall surface for the purpose of producing the appearance of buildings and the like individually. This architectural glass brick is a building material used as a design wall that shines brightly in the room during the day and by lighting up at night, and is widely used for the outer and inner walls of buildings, monuments, etc. . In addition, a landscape block for building in which such a glass brick and a fired brick such as general ceramics are combined has been developed.

For example, Patent Document 1 discloses a building landscape block that is a perforated brick block for a book wall that does not bear proof stress, and is fitted with a light-transmitting material in a through hole that transmits light from the back side to the front side. ing. Patent Document 2 discloses a composite glass block body in which glass is melted and poured into a metal frame, solidified by cooling, and the metal frame and glass are integrated. Furthermore, in patent document 3, it consists of a 1st frame, the 2nd frame fitted to this as a translucent block for construction, and translucent members, such as plate glass clamped between these both frames. Are disclosed. Patent Document 4 includes clay and / or earth soil as a main component, 20 to 30 parts by weight of glass powder is blended with 100 parts by weight of the main component, and is fired at a temperature of 900 to 1000 ° C. There is disclosed a lightweight fired building material in which a foaming agent made of foamed glass obtained by foaming a foaming agent obtained by heating a foaming agent blended in an appropriate amount with glass powder in a hollow portion of a peripheral structure is heated.

JP 2001-152601 A JP 2001-182214 A JP 2001-288844 A JP 2006-321108 A JP 2005-59567 A

  However, the architectural landscape block according to Patent Document 1 adheres glass to the through-hole of a perforated brick block, so it is difficult to accurately determine the bonding position, and brick and glass masking are required. There are problems such as work that requires subsequent curing becomes difficult, and the finish is poor and the cost is high.

  Moreover, the composite glass block body of the metal frame and glass by patent document 2 does not have consideration with respect to the damage of the metal frame at the time of high temperature at the time of glass pouring, or a deformation | transformation of a metal frame, and the vibration and temperature after construction of a composite glass block body Problems such as lack of consideration for glass breakage due to dimensional changes due to changes are pointed out.

  Since the translucent block by patent document 3 consists of the 1st frame body which fits, the 2nd frame body, and the translucent member clamped by these, there are many components and it becomes expensive by assembly process expense etc. Not only that, but also when a glass plate is used for the translucent member, there is a problem of breakage.

  The fired building material according to Patent Document 4 is such that the hollow portion of the outer peripheral structure is filled with foam, and it aims to reduce weight and to obtain excellent heat insulating properties and sound insulation properties. The invention has been made mainly for the purpose of improving the heat insulating properties of building materials. According to this invention, since the construction in which the hollow portion does not become the design surface is performed, the design is from the past, and the decorative effect is not improved.

  Since the decorative structure by patent document 5 fixes several thick semi-transparent glass pieces with a filler in the cavity part penetrated to the front and back of the perforated block for construction, 1. 1. a step of covering one end of the cavity of the frame; 2. a step of filling sand into the remaining hollow portion of the hollow portion of the frame; 3. placing glass pieces on the sand; 4. covering the upper surface of the glass piece with a film so that the filler does not remain attached to the glass piece; 5. filling the gap between the glass pieces with a gel filler; 6. When the filler is solidified, the process of removing one end of the cavity and removing the sand packed in the cavity; At least seven steps in total, such as a step of removing the film, are required, resulting in a very high manufacturing cost. Moreover, since a plurality of thick translucent glass pieces are fixed with a filler, there is a problem that it is impossible to manufacture a uniform product.

  The present invention provides an architectural decorative brick having a translucent window made of a sintered glass body that solves the above-described conventional problems such as frame damage, deformation, and glass breakage, and a method for manufacturing the same and a decorative decorative wall surface structure for the building. It is a technical subject to do.

The architectural decorative brick of the present invention made to solve the above technical problem is made of a fired brick material that does not substantially deform at a high temperature of 1000 ° C., and a perforated brick block having a through hole portion, A glass sintered body that is disposed in the through-hole portion, has an average transmittance of 15 to 85% in a wavelength range of 400 to 700 nm at a thickness of 7 mm, and a thermal expansion coefficient of 60 × 10 ⁻⁷ / K or less; And the glass sintered body disposed in the through-hole portion of the perforated brick block is fused and fixed to the inner wall surface of the through-hole portion to seal the through-hole portion.

In the decorative brick for building of the present invention, the glass sintered body arranged in the through-hole portion of the perforated brick block is fused and fixed to the inner wall surface of the through-hole portion to seal the through-hole portion, for example By filling a through-hole part of a perforated block for a book wall made of sintered bricks such as typical ceramics with a translucent glass body and heating to 800 to 1000 ° C., The average transmittance in a wavelength range of 400 to 700 nm at 7 mm is 15 to 85%, and a glass sintered body having a thermal expansion coefficient of 6.0 × 10 ⁻⁶ / K or less is formed, and at the same time, a translucent It means that the glass sintered body is fixed by being fused and integrated with the sintered brick. Such a decorative brick for building of the present invention can reduce the manufacturing cost and can be provided to the market at a low cost. It is important for maintaining the dimensions that the perforated brick block is made of a brick material which is not deformed substantially when heated to 1000 ° C., for example, at a high temperature of 1200 ° C. or higher. is there. Here, “substantially not deformed when heated to 1000 ° C.” means that when stress is applied at a high temperature of 1000 ° C., creep deformation may occur. This means that in the firing step for forming a bonded body, shrinkage deformation with a slight dimension within an allowable range may occur.

  Moreover, as for the decorative brick for building of this invention, a glass sintered compact is in a through-hole part through the fireproof buffer layer whose thickness is 10-50 micrometers on the inner wall surface of the through-hole part of a perforated brick block for building walls. It is preferable that the refractory material such as alumina or zircon functions as a buffer layer, and intervening this is a countermeasure against breakage of the glass sintered body.

  Moreover, it is preferable for the decorative brick for building of the present invention to contain a colorant in the glass sintered body because the decorative effect of the light-transmitting portion made of the glass sintered body of the decorative brick can be improved.

As the colorant used for the glass sintered body in the present invention, among the group of ZrSiO ₄ , Co ₃ O ₄ , MoO ₃ , Er ₂ O ₃ , CeO ₂ , NiO, TiO ₂ , FeO and Fe ₂ O ₃ , It is preferable that 1 or more is included. In the present invention, the glass sintered body is one or more of the group consisting of ZrSiO ₄ , Co ₃ O ₄ , MoO ₃ , Er ₂ O ₃ , CeO ₂ , NiO, TiO ₂ , FeO and Fe ₂ O ₃ dissolved in the glass. Although it is preferable that it is colored by the colorant to be contained, since it does not hinder the fluidity of the glass when forming the glass sintered body, the colorant may be a pigment such as ZrSiO ₄ up to 1% by mass. Can be used as When this colorant is ZrSiO ₄ , it is milky white, when it is Co ₃ O ₄ , it is blue, when it is MoO ₃ , it is milky white, when it is Er ₂ O ₃ , it is pink, and when it is CeO ₂ , it is pink In the case of NiO, an ocher color is exhibited, in the case of TiO ₂ , a yellow color is exhibited, in the case of FeO, a black color is exhibited, and in the case of Fe ₂ O ₃ , a reddish brown color is exhibited. Moreover, the sintered glass body which exhibits various color tones can be obtained by combining these colorants. Furthermore, when used in combination with other oxide colorants, many colors are possible.

  In addition, it is more preferable that the decorative brick for building of the present invention includes a fluorescent material, a phosphorescent material, and the like as the light emitting material when the glass sintered body includes the light emitting material, thereby enabling various light effects.

As the luminescent material in the present invention, for example, it can be used as long as the luminescence is not lost even at a firing temperature exceeding 1000 ° C., a phosphorescent material in which SrAl ₂ O ₄ is doped with Eu ²⁺ and Dy ³⁺ , ZnS with Cu ⁺ , A fluorescent material doped with Al ³⁺ is suitable. Further, in the present invention, when the glass body is sealed with the light emitting material, the light emitting material and the glass piece are sintered and then sealed and sealed in the glass body to which the light emitting material is fused. Or a glass body such as a light emitting material that is partially embedded by adhering to a fused glass body. When using a glass body sealed with such a light emitting material, the appearance is different from that produced by directly dispersing a luminescent substance in the glass body, and the glass sintered body of a decorative brick for construction is used. A pattern having a sense of depth is observed on the design surface.

  In the present invention, the luminescent material includes a phosphorescent material. In particular, when a phosphorescent material is used as the luminescent material, the luminous ability of the phosphorescent material is reduced when oxidized by the outside air during firing, and the luminous ability is lowered even after firing due to oxidation with the outside air or contact with moisture. Therefore, in the present invention, when the light emitting material is previously covered with a light-transmitting glass to prevent oxidation, that is, when a small glass body in which the light emitting material is sealed is used, semi-permanently stable light emission is produced in the sintered glass body after firing. It becomes possible. Therefore, even if a glass body with a light emitting material sealed on the outer surface of the glass sintered body is disposed, the light emitting ability of the surface is hardly lowered as compared with the conventional one in which the light emitting material is uniformly dispersed. Does not happen.

  In the present invention, the sintered glass body is produced from a light-transmitting glass body having an average transmittance of 15 to 85% at a thickness of 7 mm in the wavelength range of 400 to 700 nm after firing. Is scattered, and scattered light that is kind to the eyes is emitted from the design surface. That is, in the wavelength range of 400 to 700 nm, when the average transmittance at a thickness of 7 mm of the glass sintered body is lower than 15%, light from the light source is hardly transmitted, so that it is hardly noticeable as a design surface in a dark place. For example, it becomes difficult to perform functions such as a guide light, a sidewalk light, and a foot lamp. On the other hand, if the average transmittance exceeds 85%, the inner structural material can be seen through when it is constructed, or the light from the light source is directly in the eyes, which is not preferable.

  Further, in the present invention, it is preferable that the design surface of the glass sintered body is uneven, since the regular reflectance is 2% or less because soft light is emitted and is easy on the eyes. Moreover, although it becomes uses other than a wall, even if it gets wet with rain, it will become a thing which is hard to slip.

Further, in the glass sintered body according to the present invention, it is important for maintaining the strength over a long period that the thermal expansion coefficient of the glass is 60 × 10 ⁻⁷ / K or less. Further, the glass is made of one or two or more kinds of glass selected from the group consisting of soda-lime glass, borosilicate glass, aluminosilicate glass, and aluminoborosilicate glass, and is resistant to thermal shock and chemical resistance. because of its excellent, and the thermal shock during cooling in the heat treatment step, without damage in thermal shock due to the temperature difference due to severe climatic changes, in terms of excellent weather resistance, B ₂ O ₃ -SiO ₂ system It is preferably made of Al ₂ O ₃ —SiO ₂ or B ₂ O ₃ —Al ₂ O ₃ —SiO ₂ glass.

In the present invention, when the glass sintered body has 10 ² to 10 ¹² bubbles / kg in the glass, the average transmittance at a thickness of 7 mm is 15 to 85 in the wavelength range of 400 to 700 nm. % Is preferable. That is, because the bubbles of the glass sintered body reflect or scatter light incident on the glass sintered body from the light incident surface, the average transmittance can be adjusted by the amount of bubbles. Further, in the present invention, since the glass sintered body contains 10 ² to 10 ¹² bubbles per kg, it becomes translucent opaque, so that a person or an object can be clearly seen while having translucency. It is easy to obtain so-called privacy protection that cannot be done, and when a light source is installed on the back side, the light from the light source is scattered by the bubbles of the glass sintered body, as if the glass sintered body from the design surface side Since it appears to emit light, it is preferable in terms of design. When the number of bubbles made of less glass than 100 per 1kg effect is obtained hardly mentioned above, when consisting of more glass than 10 ¹² per 1kg, average transmittance of visible light in thickness 7mm than 15% It tends to be low and the mechanical strength is easily lost. In addition, a bubble refers to what has a diameter of 0.01 mm or more.

  In the present invention, the glass sintered body may be phase-separated if the average transmittance at a thickness of 7 mm is 15 to 85% in the wavelength range of 400 to 700 nm. In addition, the preferable range of average transmittance is 30 to 80%, and more preferably 40 to 65%. In the present invention, the average transmittance means the transmittance by linear light and is different from the transmittance including scattered light measured using an integrating sphere.

Moreover, the manufacturing method of the decorative brick for building of this invention is 0.01- with respect to the several glass body using the glass whose thermal expansion coefficient is 60x10 < ^-7 > / K or less, and this glass body. A mixing step of preparing a plurality of glass bodies with a binder by mixing and stirring a mixture to which 3% by mass of a binder is added, and a perforated brick made of a fired brick material that does not substantially deform at a high temperature of 1000 ° C. A buffer layer forming step of disposing a fireproof cushioning material on the wall surface in the through hole portion of the block, and an integration for forming the transparent glass integrated layer by stacking the glass bodies with binder in the through hole portion of the perforated brick block By baking the perforated brick block on which the process and the light-transmissive glass integrated layer are formed, the average transmittance in the wavelength range of 400 to 700 nm with a thickness of 7 mm in the through hole is 15 to 85%. And a firing step of fusing and fixing the porous sintered block to the perforated brick block.

  In the method for producing a decorative brick for building of the present invention, as a mixing step, a mixture of a plurality of glass bodies and a binder of 0.01 to 3% by mass with respect to the glass bodies is used by using a mixer or the like. This means that a plurality of glass bodies are produced by mixing and stirring. As a binder used in the mixing step, polyvinyl alcohol (Poly-Vinyl Alcohol: PVA) or the like can be used, and the addition amount is 0.01 to 3% by mass with respect to the glass body. It is. On the other hand, if the addition amount of the binder to the glass body is less than 0.01% by mass, the adhesion to the glass body becomes insufficient and uneven, and if it exceeds 3% by mass, the glass body becomes sticky. Manufacturing workability deteriorates. In the present invention, the addition amount of the binder is important to be 0.01 to 3% by mass with respect to the glass body.

  In the production method of the present invention, as the buffer layer forming step, on the wall surface in the through hole portion of the perforated brick block made of a fired brick material that does not substantially deform at a high temperature of 1000 ° C., alumina material, zircon material, etc. Any fire-resistant buffer material may be used, and it is preferable that the thickness of the glass sintered body be prevented from being easily pulled out by preventing the glass sintered body from being broken due to a buffering effect.

  In the production method of the present invention, the integration step may be any method as long as the glass body with a binder is integrated into the through-hole portion in which the buffer layer of the perforated brick block is formed to form the translucent glass integrated layer. The glass accumulation layer has a thickness that allows the glass sintered body to have a desired translucency, and may include a decorative material.

  In the production method of the present invention, as the firing step, a perforated brick block formed with a light-transmitting glass integrated layer is fired to form a glass sintered body in the through-hole portion and to be fused with the perforated brick block and fixed. The temperature for firing is 700 to 1100 ° C, preferably 800 to 1000 ° C. When the heat treatment temperature is lower than 700 ° C., the glass does not sufficiently soften and flow, and the mechanical strength is lowered. When the heat treatment temperature exceeds 1100 ° C., bubbles in the glass sintered body are reduced and the visible light transmittance is increased. In addition, the structural material can be seen through at the time of construction, and the reactivity between the glass body and the release material is increased, and the glass body and the refractory container are easily fused, which is not preferable.

In addition, in the manufacturing method of the present invention, when heat treatment is performed within the temperature range in which the glass is reboiled, in addition to the bubbles generated by the gaps in the glass body remaining, new bubbles are generated inside the glass sintered body by the reboil. Therefore, it is preferable. The temperature at which the gas dissolved in the glass becomes bubbles and the reboil begins to appear is about 50 ° C. higher than the softening point of the glass. When the heat treatment temperature is further increased, bubbles are generated more actively inside the glass, but the viscosity of the glass also decreases, so the generated bubbles gradually increase, float and release to the outside of the glass. Will be. Here, the temperature range in which the glass reboils refers to the temperature range from when gas dissolved in the glass starts to appear as bubbles until it is released to the outside of the glass. For example, B ₂ O ₃ − the SiO ₂ -based glass is about 800 to 1000 ° C..

  Moreover, as for the manufacturing method of the decorative brick for construction of this invention, it is preferable that a mixing process mixes and stirs the mixture which added 0.01-0.2 mass% coloring agent with respect to the glass body. . When the added amount of the colorant is less than 0.01% by mass with respect to the glass body, the adhesion of the colorant to the glass body becomes insufficient, resulting in uneven coloring, and sufficient color development cannot be achieved. . On the other hand, if it exceeds 0.2% by mass, the coloring effect and cost are not economical.
