Description

  The present invention relates to an architectural glass block that is excellent in heat insulation, sound insulation, and translucency, and is widely used as an outer wall or an inner wall, and particularly can be easily constructed without requiring skill. The present invention relates to an assembly and a glass block built-in wall surface structure using the assembly.

  In general, a glass block for building is formed by welding and integrating a pair of glass molded bodies having a bottomed and uncovered box-shaped bottom part with a translucent surface at the open end of each other. It is a hollow building material having a translucent surface on both sides. The glass block panel formed by aligning and arranging a plurality of such glass blocks in the vertical and horizontal directions is excellent in translucency, heat insulation, and sound insulation. Widely used for wood, inner wall material, daylighting roof, veranda wall surface, partition material, etc.

  In recent years, with the diversification of the design of buildings and houses, wall surfaces rich in decoration have been demanded. Therefore, a glass block that is partially fitted with a translucent architectural glass block and is colored on the outer wall surface, inner wall surface, partition wall surface, veranda wall surface, or the architectural glass block wall surface. Walls and the like that are fitted in are proposed.

  As a method that can be easily constructed without requiring skill, for example, Patent Document 1 discloses that a plurality of glass blocks arranged in one direction, a frame that surrounds the outer periphery thereof, and short sides that face each other. There is disclosed a glass block panel including a mounting portion embedded in the glass block and a joint member disposed between the glass blocks and between the glass block and the frame and fixing the glass block to the frame.

  Patent Document 2 discloses a glass block panel in which a plurality of glass blocks are arranged on a plane, and the periphery of the aggregate of the glass blocks and the joints between the glass blocks are formed of a transparent resin. ing.

  However, since the glass block panel described in Patent Document 1 handles the fixing force between the glass blocks with a frame, it is necessary to form the frame with a material having excellent rigidity and strength. In addition, there is a problem that it is not possible to sufficiently buffer the temperature change after the construction and the stress from the case during the earthquake.

  In the glass block panel described in Patent Document 2, a transparent resin is poured and cured between the glass block and the mold and between the glass blocks to fix the glass block in the resin. For this reason, the glass block and the formwork are fixed without play by the transparent resin cured material, and as before, the impact during transportation before construction, the temperature change after construction, and the stress from the housing during earthquake are sufficient. There is a problem that it cannot be buffered.

  The present invention has been made in view of the above problems, and is a building glass block capable of sufficiently buffering shocks during transportation before construction, temperature changes after construction, and stress from the housing during an earthquake. It is a technical problem to provide an aggregate and a glass block built-in wall surface structure using the architectural glass block aggregate.

The glass block assembly for building according to the present invention has a plurality of glass blocks formed by welding the open edges of a pair of glass moldings having a bottomed and uncovered box shape whose bottom surface is a translucent surface, and the side surfaces of a plurality of glass blocks have a connecting portion for connecting with an adhesive, the welded portion of the open edge of the pair of glass shaped material is provided so as to project from the side surface of the glass block, adhesives, glass It is applied to the region including the welded portion on the side surface of the block .

  As described above, the architectural glass block aggregate of the present invention is formed by connecting and integrating the adhesives on the side surfaces of the plurality of glass blocks so as to be connected and integrated. Thus, it is necessary to reinforce the outer periphery of the glass block connector with a frame made of a hard structural material (for example, an aluminum plate, a stainless steel plate, a plastic molding material, etc.) by handling the fixing force between the glass blocks at the connecting portion. Disappear.

  Further, in order to omit an outer reinforcing material such as a frame that winds or surrounds the outer periphery of the aligned glass blocks, the glass block connector is less than 0.8 m in length from the connecting part to the tip of the glass block farthest away. It is important to reduce the moment load applied to the connecting portion. For example, a glass block having dimensions of 190 mm × 190 mm × 95 mm can be used as long as less than 5 hollow glass blocks are arranged and bonded in one direction. Specifically, the glass block connector is a combination of two pairs of glass blocks, one row, L shape, or three glass blocks arranged in a row, and two rows x two columns or a substantially Z shape. It is preferable that the length from the connecting part to the tip of the glass block is short, such as a structure in which four glass blocks are bonded together, and a large moment load is not easily applied to the connecting part. A glass block assembly employing such a glass block connector is easy to handle and very convenient when it is locally applied to the wall surface in order to improve lighting and wall surface design. Further, the building glass block aggregate has a size that can be disposed avoiding the position of reinforcing bars such as longitudinal bones arranged in the wall surface, and does not reduce the work efficiency of construction. preferable.

Moreover, the adhesion area between glass blocks should just be a dimension which can connect a glass block safely, for example, in the normal size glass block which has a dimension of 190 mm x 190 mm x 95 mm, an outer periphery dimension is about (PHI) 50mm (about 2000mm < ² >). ) It only needs to be bonded in a considerable area. As the adhesive, any adhesive can be used as long as it has adhesiveness to glass and solidified adhesive itself has practical strength and has weather resistance for construction. For example, an epoxy-based adhesive, an acrylic adhesive, a polyurethane-based adhesive, or the like can be used, and a two-component room temperature curable epoxy resin-based adhesive that has a proven record for construction is suitable. Moreover, a glass block aggregate | assembly can be rapidly produced as an adhesive is a quick-drying type whose intensity | strength comes out in about 1 hour.

  In addition, the architectural glass block aggregate is formed by providing a buffer layer on a side peripheral surface of a glass block connector including a plurality of glass blocks integrated by a connecting portion.

  As a result, a buffer layer made of a soft material such as rubber material can be arranged on the side peripheral surface of the glass block connector, so that impacts during transportation before construction, temperature changes after construction, and housing during earthquakes Can buffer the stress and protect the glass block.

  As a buffer layer applied around the glass block connector, the welded part, which is the weakest part of the strength of the glass block, is protected over the entire circumference, and the impact during transportation before construction and the temperature after construction Anything that can buffer the change and the influence from the enclosure at the time of the earthquake can be used. For example, polyethylene foam is often used, but various rubber materials such as neoprene rubber (CR), ethylene propylene rubber (EPDM), hyperon rubber (CSM), silicone rubber (SI / Q), polyurethane foam, adhesive layer Those with a mark are suitable. The optimum thickness of the buffer layer is 1 mm to 3 mm for indoor construction with relatively little temperature change, and 3 mm to 8 mm for outdoor construction.

  If the mass of the glass block aggregate exceeds 25 kg, one worker cannot easily handle it. In order to handle such a glass block assembly efficiently and safely, an auxiliary lifting machine is required, and when the work space is small, the lifting machine does not enter and construction becomes difficult, and two or more workers are required. This increases the construction cost. Therefore, if the mass of the glass block aggregate is 25 kg or less (preferably 20 kg or less), handling when producing the glass block aggregate can be easily performed by one operator. In addition, even at the construction site, the construction worker can easily handle the construction such as transporting, mounting and fine adjustment of the glass block aggregate safely without using a lifting machine.

  If the adhesive between the glass blocks can be seen with the glass block aggregate applied, the appearance will be poor. In order to conceal this adhesive, if joint treatment such as mortar joint finish is applied to the gap between the glass blocks connected by the adhesive, the joint thickness may be uneven and the mortar joint may have uneven color. . Therefore, if a backup material is attached to at least the light-transmitting surface side of the connecting portion between the glass blocks, the cured adhesive can be hidden and the joint thickness can be made uniform. Moreover, when performing sealing joint finishing, since the sealing material is blocked by the backup material and does not enter the back of the gap between the glass blocks, the sealing material can be saved and the cost can be reduced.

  Moreover, if the glass block aggregate of the present invention includes a glass block having a curved light-transmitting surface, design variations can be increased. For example, in order to correspond to a concrete block wall having a corner portion, if the light transmitting surface of the glass block constituting the glass block aggregate has a curved surface along the curvature of the wall surface, the continuity with the wall surface is maintained. A desired translucent surface can be formed. Specifically, for example, when a glass block whose light-transmitting surface is a curved surface having an angle of 90 degrees is used, it can be used for a corner portion of a 90-degree concrete block wall.

  The building glass block built-in wall surface structure according to the present invention comprises the building glass block aggregate of the present invention, and a fixing material and joint material filled around the building glass block aggregate. It is characterized by. For example, the architectural glass block aggregate of the present invention is locally loaded on a concrete block wall or a brick wall to provide a translucent part at a desired site to improve design, and a color different from the surroundings, It can be applied to a wall surface in which a patterned glass block assembly is partially fitted, or a wall surface using only a building glass block assembly.

  A fixing material fixes the structure (concrete block etc.) and glass block aggregate which comprise a wall surface. For example, cement mortar, resin mortar, etc. can be used, and cement mortar is preferable in terms of material cost and workability. The joint material is a material that fills the gap between the structure constituting the wall surface and the glass block aggregate, and has a fixing force that can fix the structure and the glass block aggregate independently like a fixing material. Made of no material. For example, decorative joint materials and backup materials are applicable, and it is possible to adopt amorphous products used when constructing buildings in the field, and regular processed products used when assembling glass block panels in the factory in advance. It is. For example, a mortar joint such as a silicone sealant or a waterproofing agent can be used as a decorative joint material, and a mortar joint is preferable in terms of design continuity with other parts.

  In the above-described building glass block built-in wall surface structure, the buffer layer can buffer the load stress from the housing at the time of a temperature change or an earthquake, so that it is possible to efficiently construct a wall surface on which the glass block is hardly damaged. In addition, material costs can be reduced without using expensive reinforcing materials such as a frame surrounding the glass block assembly, and it is possible for a construction worker to easily construct a wall that incorporates a glass block assembly. Become.

  According to the glass block assembly for building according to the present invention, welding is the weakest part in terms of strength of the glass block from transportation before construction without using an expensive frame surrounding the outer periphery of the glass block connector. The part can be protected.

  In addition, the glass block assembly for building of the present invention in which the buffer layer is applied to the side peripheral surface of the glass block connector is an external force that is applied to the buffer material from the housing at the time of temperature change or earthquake even after the construction. It is possible to buffer the influence of the glass block and prevent breakage of the glass block.

  Hereinafter, an example according to an embodiment of the present invention will be described in detail with reference to FIGS.

  FIG. 1 shows an architectural glass block assembly 10 according to an embodiment of the present invention, and a plurality (two in the illustrated example) of glass blocks 11 and side surfaces 11d of the glass blocks 11 are interposed with an adhesive. It has the connection part 12 to connect, and the buffer layer (buffer sheet 14) given to the side peripheral surface 13a of the two glass blocks 11 (glass block connection body 13) integrated via the connection part 12. FIG. In the following, for convenience of explanation, among the rectangular design surfaces (surfaces shown in FIG. 1) of the architectural glass block aggregate 10, the short side direction is the vertical direction and the long side direction is the width direction. The direction perpendicular to the two directions (the direction perpendicular to the plane of FIG. 1) is referred to as the thickness direction.

  As shown in FIG. 4, the glass block 11 is formed by welding and integrating a pair of glass molded bodies 11 a having a bottomed and uncovered box shape whose bottom surface is a light-transmitting surface 11 c at their open edges. . The outer periphery of the translucent surface 11c is surrounded by a frame 11b. The glass molded body 11a is formed, for example, in a size of 190 mm × 190 mm × 47.5 mm and a wall thickness of 5 mm at the open end portion. In this case, the glass block 11 has dimensions of 190 mm × 190 mm × 95 mm. Each glass molded body 11a has a trapezoidal shape in which the open side is narrowed in a side view, whereby the side surface 11d of the glass block 11 has a shape recessed toward the center in the thickness direction (welded portion 11e). ing.

  Manufacture of the building glass block aggregate 10 is performed as follows, for example. First, molten glass is press-molded with a mold to form a pair of glass molded bodies 11a. The glass block 11 is formed by welding the open end edges of the pair of glass molded bodies 11a. Two glass blocks 11 formed in this way are prepared, and an adhesive (for example, Cemedine Co., Ltd .: two-component room temperature curing type epoxy resin adhesive model number 1500) is applied to the center of the side surface 11d of one glass block 11. It is applied so that the adhesion area is equivalent to about Φ50 mm. The side surface 11d of the other glass block 11 is brought into contact with this adhesive, and the two glass blocks 11 are arranged in the width direction and positioned and fixed in the mold until the adhesive is cured. When the above-described adhesive is used, the adhesive is completely cured by curing for half a day, and the glass block connector 13 is taken out from the mold after curing.

  Next, the backup material 15 is attached to both sides in the thickness direction of the connecting portion 12 (the portion where the adhesive is cured). The backup material 15 has, for example, a bar shape (round bar, square bar, cross-section trapezoidal shape, etc.) and is disposed along the frame 11b of the glass block 11 on both sides in the thickness direction of the connecting portion 12 as shown in FIG. The The backup material 15 is formed of a material having resilience, and is formed of, for example, a foam material (polyethylene foam or urethane foam). The backup material 15 is formed to have a width slightly larger than the joint width W (interval between the frames 11b and 11b), and is pressed into the gap between the side surfaces 11d and 11d of the glass blocks 11 and 11 while being compressed and deformed, and the back side of the frame 11b. It is attached by restoring with. Thus, by arranging the backup material 15 on both sides of the connecting portion 12 in the thickness direction, the adhesive of the connecting portion 12 can be blinded. As shown in FIGS. 2 and 3, when the mortar joint 16 is applied on the outer side in the thickness direction of the backup material 15, the mortar joint 16 is disposed along the rod-shaped backup material 15. Can be made uniform in thickness. When the mortar joint 16 is formed by sealing joint finishing, the joint material can be saved by damming the sealing material of the mortar joint 16 with the backup material 15.

  The shape of the backup material 15 is not limited to this. For example, as shown in FIG. 5, a shape in which a region to which an adhesive is applied is cut out in advance can be used. In the illustrated example, edges on both sides in the thickness direction are arranged along the frame 11b, and a circular cutout portion 15a is formed at the center thereof. In this case, with the backup material 15 disposed on the side surface 11d of one glass block 11, an adhesive is applied to the cutout portion 15a of the backup material 15, and then the side surface 11d of the other glass block 11 is brought into contact with the adhesive. Thereby, the two glass blocks 11 are connected by the circular connection part 12.

  After the two glass blocks 11 are connected to form the glass block connecting body 13, a buffer sheet 14 as a buffer layer is attached to the side peripheral surface 13 a of the glass block connecting body 13. The buffer sheet 14 is provided in a region (region on the center side in the thickness direction) of the side peripheral surface 13a of the glass block connector 13 that is retracted from the light transmitting surface 11c on the front and back surfaces of the glass block 11. In the illustrated example, a polyethylene foam buffer sheet 14 having a thickness of 5 mm and a width of 75 mm is wound as a buffer layer on a region of the side peripheral surface 13 a that is 10 mm away from the light transmitting surface 11 c. The buffer sheet 14 is attached to the side peripheral surface 13a of the glass block connector 13 with, for example, a double-sided adhesive tape. As shown in FIG. 2, when the buffer sheet 14 is provided in the region on the inner side in the thickness direction of the frame 11 b on the side peripheral surface 13 a of the glass block connector 13, the buffer sheet 14 is placed on the outer periphery of the glass block connector 13. The amount of protrusion can be reduced. In addition, the arrangement | positioning location of the buffer sheet 14 is not restricted above, For example, you may distribute | arrange so that the thickness direction both ends edge of the buffer sheet 14 may cover the frame 11b. In this case, the frame 11 b can also be protected by the buffer sheet 14.

  Thus, the architectural glass block aggregate 10 is completed. This building glass block aggregate 10 is supported by a connecting portion 12 made of an adhesive to fix the glass blocks 11 and 11. Therefore, the buffer layer 14 is not required to have a function of bonding the glass blocks 11 and 11, and a material having a high buffer property such as a rubber material can be used. By arranging the buffer layer 14 around the glass block connecting body 13 in this way, the shock at the time of transportation before construction, the temperature change after construction, and the stress from the housing at the time of earthquake are buffered. Can be protected. In particular, in the glass block 11, the welded part 11 e between the glass molded bodies 11 a is more fragile than other parts, and thus it is effective to protect the welded part 11 e with the buffer layer 14.

  The architectural glass block aggregate 10 having the above-described configuration has dimensions of 385 mm × 190 mm × 95 mm and a mass of 5.5 kg. In this embodiment, the joint width W (refer FIG. 1) in the design surface of the connection part 12 of the glass block coupling body 13 is set to 5 mm. Since each glass block 11 has a dimension of 190 mm × 190 mm × 95 mm, the dimension of the design surface of the building glass block aggregate 10 is 385 mm × 190 mm.

  FIG. 6 shows a building glass block built-in wall surface 20 according to the present embodiment, which is formed by stacking concrete blocks (JIS A 5406) 31 having a module nominal size of 400 mm in length and 200 mm in height. The glass block aggregate 10 is arranged in a predetermined portion having a good balance as the design of the wall surface 20. Since the design surface of the glass block aggregate 10 is slightly smaller than the concrete block 31 (385 mm × 190 mm), it can be incorporated into the wall surface 20 without a sense of incongruity. As shown in FIG. 7, the glass block aggregate 10 is loaded via a cement mortar 32, and the joint portion is covered with a decorative joint material 17.

  When constructing the building glass block built-in wall 20, the building glass block assembly 10 of the quantity used and the concrete block 31 having a module nominal size of 400 mm in length and 200 mm in height are used only for the concrete block 31. Prepare the quantity by subtracting the quantity of the building glass block aggregate 10 from the required quantity when forming the wall surface, and start the construction of the block wall. When stacking the concrete blocks 31, the building glass block aggregate 10 is passed through the cement mortar 32 in the same manner as the concrete blocks 31 in a predetermined portion where the vertical stripes of the wall surface under construction are not arranged. After stacking and arranging a backup material as necessary, a makeup joint material 17 made of cement mortar is filled and applied. Finally, the building glass block built-in wall surface 20 shown in FIG. 6 in which the building glass block aggregate 10 is incorporated is obtained.

  The present invention is not limited to the above embodiment. For example, in the said embodiment, although the case where the translucent surface 11c of each glass block 11 was a plane was shown, it is good not only as this but the structure containing the glass block whose translucent surface is a curved surface. FIG. 8 shows an architectural glass block assembly composed of the glass block 11 shown in the above embodiment having a planar light-transmitting surface 11c and the corner glass block 19 having curved light-transmitting surfaces 19c1 and 19c2. 18 is shown. Since the light-transmitting surfaces 19c1 and 10c2 of the corner glass block 19 are curved surfaces having an angle of 90 degrees, they can be used for a concrete block wall having a 90-degree corner.

  Between the glass blocks 11 and between the glass block 11 and the corner glass block 10 are fixed by a connecting portion 12 using an adhesive (see FIG. 8B). The size of the larger light-transmitting surface 19c1 of the corner glass block 19 is 90 × 120 mm by a curved surface of about 20 mm, and the smaller light-transmitting surface 19c2 is a curved surface having a radius of curvature of 25 mm. . In the glass block aggregate 18 as a whole, the dimension in the long side direction (left and right direction in FIG. 8A) is 520 mm, and the dimension in the short side direction (vertical direction in FIG. 8A) is 120 mm. The mass of the glass block aggregate 18 is 7.8 kg.

  The present invention is also applicable to a ceramic block other than a glass block, a block made of a brittle material such as ceramics, and a wall surface using such a hollow block.
