Description

  The present invention relates to a daylighting block construction for daylighting used for building skylights, stairs, underpass ceilings, and the like, and a construction method thereof.

  In general, when daylighting such as a skylight, a staircase, and an underpass ceiling is performed, a glass panel in which a plurality of translucent glass blocks are arranged in a support frame is used.

  As this kind of technology, techniques as disclosed in Patent Documents 1 to 4 are conventionally known. For example, as shown in FIG. 12, a frame-like spacer 12 is placed on an edge 11a of a cast iron lattice frame 11, and a prism glass 13 which is one of daylighting glass blocks is placed thereon, and the joint portion 14 is placed. By forming the silicone sealing layer 15, the waterproof mortar layer 16, and the waterproof decorative mortar layer 17 in this order, the lighting block construction body 10 was produced and then carried to the site and fixed to the housing 18. In addition, after attaching the lattice frame 11 to the housing 18 in the field, the lighting block construction body 10 may be produced and applied in the same manner as described above.

In recent years, in order to support various designs, the number of glass block shapes, frame shapes that support them, and frame opening shapes that require a variety of short delivery times is increasing. On the other hand, companies that produce castings in Japan are on a downward trend, and there are situations where it is difficult to respond.

  Since the conventional lighting block construction has a complicated lattice shape of the support frame, as shown in FIGS. 13 (A) and 13 (B), a cast iron made using a mold has been used. Cast iron products are limited in size due to manufacturing problems that require a mold. When the housing opening area is large, a joint is provided, and a reinforcing beam is required. It was not preferable. Further, the yield strength in the blowing direction is almost determined by the weight of the daylighting glass block and the joint material since no bonding force can be expected between the daylighting glass block and the support frame. For this reason, it was difficult to use it in a place with a large blowing force.

  Moreover, the cast iron frame is liable to cause brittle fracture, and it is necessary to increase the safety factor with respect to the required strength. For this reason, there are problems such as an increase in cost and an increase in product weight. Furthermore, in the case of cast iron, the product accuracy is poor, and the frame-shaped spacer for protecting the glass block may not fit in the lattice frame. For this reason, the product size of the frame-shaped spacer must be set small so that there is a margin, and the problem that the position easily shifts even during installation of the daylighting glass block and the joint does not pass easily occurs. In addition, in the case of cast iron frames, the surface finish of the frame spacer installation surface is poor, and during construction the kneading water and waterproofing layer agent before the waterproofing mortar dries and solidifies, and after construction the waterproof mortar and waterproofing layer Deteriorates and cracks occur. Water that has entered from such a place may enter the indoor side through a gap where the frame spacer and the frame are not in close contact, and water leakage may occur.

  Conventionally, the opening for daylighting in the support frame has a monotonous design with only a square shape. Moreover, since the rib part is exposed to the indoor surface, the cast iron is not preferable because the design tends to be monotonous. In the case of a cast iron frame, if a rib (vertical metal plate) is provided inside the joint due to a problem that a thin one cannot be produced in the production of cast iron, the joint width becomes large, which is not preferable in terms of design. Further, when the joint width is increased, cracks are likely to occur in the joints, and rust is generated in the cast iron due to moisture entering from the joints, and the glass block may be affected by the expansion to cause breakage.

  In addition, in the case of a cast iron frame, when making the shape of the opening or rib plate of the support frame special, it is necessary to start from the production of the mold, and a production period of 2 to 3 months is required. Since the size of the opening of the frame on which the support frame is constructed varies, it is necessary to prepare (inventory) many standard products in order to achieve a short delivery time. Manufacturing a non-standard product requires a long period of one to two months, and there is a problem that it is not possible to meet the demand for a short delivery time.

  Further, when manufacturing a support frame 19 other than cast iron as shown in FIG. 14, the frame body 19a, the metal vertical plate 19c, and the four members of the two types of horizontal plates 19b1 and 19b2 are welded together. Since the light-transmitting portion 19d is formed, it takes time for welding work and correction, and the cost becomes high.

  The object of the present invention is to support a short delivery time without requiring standard products and stocks for the requirements of free size and design for the support frame that supports a plurality of translucent glass blocks. Construction of a lighting block structure and its construction, which is easy to construct a glass block for daylighting and can improve waterproof (waterproofing) performance with a support frame that is lightweight and has an appropriate safety and cost balance. It is to provide a method.

  The lighting block construction according to the present invention includes a plurality of light-transmitting blocks, a support frame that supports the light-transmitting blocks by arranging and arranging the light-transmitting blocks in a portion where the light-transmitting portions are formed, and a light-transmitting block. In the lighting block construction comprising the joints located between each other and between the translucent block and the support frame, the support frame is made of metal that surrounds the outer periphery of the aligned translucent block group. Frame, a metal horizontal plate having a translucent portion formed at the portion where the translucent block is disposed, and a member disposed in one direction between the translucent blocks and facing the frame body Are formed by joining metal vertical plates (rib plates).

  As a support frame used in the present invention, a light grooved steel material made of stainless steel or the like, a frame body processed from a channel steel material, and a steel plate supporting a translucent block, which is horizontal to the opening of the frame body. Made of flat horizontal steel and flat bar steel, etc., which mainly determines the strength of the support frame, and is assembled with a vertical plate (rib plate) perpendicular to the horizontal plate by a welding method Can be used. As a horizontal plate, if the transparent part is formed in the part where the transparent block is arranged by punching process such as fusing of metal plate or punching press, etc., it will be ordered This is preferable in terms of prompt response productivity and manufacturing cost. As a vertical board (rib board), it consists of steel materials etc. which can be easily joined to a frame and a horizontal board, and a commercial flat bar steel material etc. can be used. Since the vertical plate (rib plate) has one side joined to the horizontal plate and both ends joined between the opposing members of the frame, the strength of the support frame is determined by the size of the vertical plate (rib plate). Will be. Further, since the vertical plate (rib plate) has a height embedded in the joint, it is preferable because the indoor surface has a clean design as shown in FIG. Furthermore, it is preferable because the rough surface of the frame-like spacer installation surface, which is a portion that tends to be a defect on the waterproof surface, can be eliminated. In addition, even when the opening shape of the support frame and the shape of the vertical plate (rib plate) are made special, it can be manufactured in about 1 to 2 weeks like the general product (about 1/4 of the conventional short). It is not necessary to have inventory except for special cases such as emergency repairs. In addition, since it has an appropriate safety factor and can be designed according to the required strength, the balance between strength and cost is good, and the product weight is reduced by about 40% compared to the case where a conventional cast support frame is used. be able to. In addition, the accuracy of the support frame is good, the product dimensions of the frame spacer are good, and it can be made equal to the interval including the joint width, so it is difficult to shift the position even when installing the glass block for lighting, and the joint width is reduced. Construction can be done easily without worrying.

  In the unlikely event that cracks occur in the joints, the metal plate is preferably made of stainless steel that does not cause rust and does not adversely affect the glass. If it is, aluminum other than steel and other non-ferrous metals may be used. The horizontal plate and the vertical plate (rib plate) are preferably joined by welding in terms of strength and workability. The welding method is TIG welding, and fillet welding is performed on both sides of the portion where the horizontal plate and the rib plate are in contact. If the fillet size is in the range of 1 to 2 mm, the weld length is 30 to 40 mm and the pitch is 200 to 300 mm, it is preferable in terms of strength.

  The translucent block used in the present invention is made of a material having translucency and watertightness such as glass, ceramics, resin, etc. A so-called prism glass, a hollow block, or the like that has a side wall surface extending downward from the periphery and a bottom surface that is recessed at the center and is formed in a reverse concave shape as a whole can be used.

  In addition, the lighting block construction body of the present invention does not use other members when the support frame is formed by joining only three members of the frame body, the horizontal plate, and the vertical plate (rib plate). This is advantageous in terms of weight reduction and cost. That is, unlike the conventional support frame 19 shown in FIG. 14, it is not necessary to join the four members of the frame body 19a, the two types of horizontal plates 19b1, 19b2, and the vertical plate 19c by welding. Therefore, it can be manufactured at a cost equivalent to that of a cast iron frame without requiring a long time for welding work or correction of distortion.

  In the lighting block construction of the present invention, the support frame is characterized in that reinforcing bars are arranged in a direction orthogonal to the vertical plate, and the reinforcing bars are joined to the vertical plate by welding.

  A support frame member having a T-shaped cross section composed of a horizontal plate and a vertical plate is mainly used in the short side direction for reasons of strength. However, only the three members of the frame, horizontal plate and vertical plate (rib plate) are used. In some cases, until the joint mortar is hardened, a defect in appearance may occur in the block construction for lighting due to wrinkles and twists generated in the long side direction. Therefore, by arranging the reinforcing bars in the direction perpendicular to the vertical plate and joining the reinforcing bars to the vertical plate by arc welding, the cross-sectional performance in the long side direction of the lighting block construction is improved and the strength is improved. The amount of twisting and twisting can be reduced, and the appearance defects can be prevented. Further, the effect of improving the strength can be obtained with respect to the upward blowing force. Furthermore, in order to improve the strength of the lighting block construction body, it is preferable to weld the reinforcing bar to the vertical surface inside the frame body. As the installation position of the reinforcing bar, the inside upper side of the vertical face plate of the frame is preferable because it is easy to perform the welding operation and it is not necessary to process the vertical face plate of the frame. In terms of strength, it is best to insert the reinforcing bars between the lighting blocks. However, considering the fitting of the prism glass and the filling of the mortar, it is preferable to arrange the reinforcing bars at intervals of at least two rows.

  In the lighting block construction body according to the present invention, the support frame has a concave portion having a width and a depth of 1 mm or more or a convex portion having a width and a height of 1 mm or more continuously provided on the upper side of the vertical plate. If the anchor effect with the joint filler is improved, after the joint material flows and solidifies, it engages with the concave part or the convex part, and the glass block for lighting, the joint material and the support frame Can be firmly integrated. By providing such concave or convex portions, the vertical plate (rib plate), mortar, and daylighting glass block can be integrated with respect to the strength in the blowing direction. It can also be used in places with great power.

  Further, in the lighting block construction body according to the present invention, when the support frame has an opening shape other than the substantially rectangular shape, the transparent shape of the horizontal plate has a round shape other than the substantially rectangular shape. Shapes, triangles, polygons, stars, and the like are preferable because they can correspond to various designs.

  The construction method of the block construction for lighting according to the present invention is to produce a support frame for arranging and supporting a plurality of translucent blocks in a region where the translucent part is formed, and on the translucent part of the support frame In the method for constructing a lighting block construction body in which translucent blocks are arranged and supported, and joints are formed between the translucent blocks and between the translucent block and the support frame, the support For the production of the frame, a step of forming a frame body that surrounds the outer periphery of the group of translucent blocks arranged in alignment, and a metal plate that can be bonded to the entire inner surface or bottom surface of the frame body are prepared. A horizontal plate forming step of forming a light transmitting portion by penetrating through a portion where the light transmitting block of the plate is disposed, and a metal vertical plate is joined by welding in one direction between the light transmitting portions of the horizontal plate. The horizontal plate is melted over the rib bottom fixing process and the entire inner surface or bottom surface of the frame. A bottom wear step of joining by, and having a rib end fixing step of joining by welding the ends of the vertical plate member facing the frame.

  When producing a support frame according to the present invention, as a step of forming a frame body that surrounds the outer periphery of the aligned translucent block group, a light groove steel material, a channel steel material, and the like have an appropriate strength as an outer frame member. It can be used if it is a process that forms a ring-shaped frame by welding these ends together by welding, etc. is there.

  In addition, as a horizontal plate forming step of preparing a metal plate that can be bonded to the entire inner surface or bottom surface of the frame body and forming a light transmitting portion by penetrating through the arrangement portion of the light transmitting block of the metal plate A metal plate having a thickness that does not substantially deform over a long period of time even when supporting the outer peripheral portion of the translucent block, and one or a plurality of metals adapted to the opening size inside the frame Any method can be used as long as it is a step of preparing a plate and forming a translucent portion at a portion where the translucent block of the metal plate is arranged by punching such as fusing or punching press.

  As a rib bottom fixing process in which a metal vertical plate (rib plate) is joined by welding in one direction to the surface between the translucent portions of the horizontal plate, the metal plate is directed in one direction on the surface between the translucent portions of the horizontal plate. The vertical plate (rib plate) is placed and stood with a jig, and the lower end of the vertical plate (rib plate) is welded to the surface between the translucent parts of the horizontal plate or by welding over the entire inner surface or bottom surface of the frame. A metal vertical plate (rib plate) is placed in one direction on the surface between the translucent parts of the joined horizontal plates, and the lower end of the vertical plate (rib plate) is placed through the horizontal plate with a jig. Any process that welds to the surface between the light parts can be used.

  As a bottoming process in which the horizontal plate is joined by welding over the entire inner surface or bottom surface of the frame body, the horizontal plate is placed with the bottom surface of the frame body facing upward and joined by welding, or the inner side of the frame body. A spacer having a predetermined height is placed at three or more locations, a horizontal plate is placed thereon, and the outer periphery of the horizontal plate and the inner surface of the frame body adjacent thereto are joined by welding.

  As the rib end fixing step for welding both ends of the vertical plate (rib plate) to the member facing the frame by welding, the steps for bonding the both ends of the vertical plate (rib plate) fixed to the horizontal plate by welding, The process etc. which join the both ends of a vertical board (rib board) by welding can be used.

  Further, in the construction method of the lighting block construction body of the present invention, the step of forming the horizontal plate is a method in which a laser beam machine is used to cut through a metal plate to form a translucent part. Various shapes of punching can be easily performed, and a support frame having various opening shapes can be obtained in a short time and at a low cost. Further, according to laser cutting, since there is less influence of heat and thermal deformation is smaller than gas cutting using a preheating flame such as oxyacetylene flame or oxygen propane flame, it is possible to save labor for correcting distortion. Compared to other cutting methods, complex cutting is possible at high speed. Regardless of whether the punched shape is square or rectangular, it can be used for various designs such as round, triangular, diamond ..., star. Conventionally, the opening shape of the translucent part for the daylighting in the support frame has been a monotonous design with only a quadrangular shape with an emphasis on the daylighting area, but it is also possible to deal with complicated patterns by the laser cutting method.

  Furthermore, in the construction method of the lighting block construction body of the present invention, the desired pressure strength can be obtained by selecting the thickness dimension and / or height dimension of the vertical plate (rib plate) when producing the support frame. If equipped, the thickness and / or height of the vertical plate (rib plate) is selected according to the size of the opening of the housing, and the pressure-proof strength of the lighting block construction is set to a desired value. It becomes possible to do. Furthermore, even when the housing opening area is large, it is not necessary to provide a joint joint because the strength can be easily increased by changing the shape and size of the vertical plate (rib plate). Further, it is possible to provide a thin vertical plate (rib plate) of less than 5 mm inside the joint, which can be the same as the conventional joint width.

  Moreover, in the construction method of the block construction for lighting according to the present invention, the production of the support frame includes a reinforcing bar fixing step in which reinforcing bars are arranged in a direction orthogonal to the vertical plate and the reinforcing bars are joined to the vertical plate by welding. If it is, it will become preferable when raising the cross-sectional performance of the long side direction of the block construction for lighting, and improving intensity | strength.

  In the block construction for lighting according to the present invention, the support frame has a metal frame surrounding the outer periphery of the aligned translucent block group, and a translucent portion is formed at the arrangement site of the translucent block. A metal horizontal plate and a metal vertical plate (rib plate) disposed in one direction between the translucent blocks and extending between opposing members of the frame body are joined. It is a structure that can respond to customer's support frame free size and design requirements in a short delivery time, and it is easy to construct with a support frame that is lightweight and has an appropriate safety and cost balance. It is possible to provide a lighting block construction with improved waterproof (waterproof) performance.

  1A and 1B show a support frame 21 of a lighting block construction body 20 in the present embodiment. The support frame 21 is for 200 mm × 200 mm × 50 mm prism glass, and is all made of stainless steel. The support frame 21 has a short side of about 1.4 m and a long side of about 2.3 m. 3A and 3B, the support frame 21 includes a metal frame 21a that surrounds the outer periphery of the aligned prism glass 23 group, and a translucent portion 21d at a portion where the prism glass 23 is disposed. The formed metal horizontal plate 21b and the metal rib plate (vertical plate) 21c disposed between the opposing members of the frame body 21 in one direction among the prism glasses 23 are joined. It will be. The frame 21a of the support frame 21 uses L-shaped steel 75 mm × 60 mm × 6 mm, the rib plate 21c uses a flat bar 35 mm × 5 mm, and the horizontal plate 21b uses a 5 mm plate.

  Further, as shown in FIG. 2A, the rib plate 21c has a width and height of 1 mm at the upper part of both side surfaces of the rib plate 21c in order to improve the anchor effect with the joint filler such as a spacer combined gasket. As described above, for example, the convex portion 21c1 having a width of 1.5 mm and a height of 1 mm is provided. On the other hand, as shown in FIG. 2 (B), two grooves 20c2 having a width and a depth of 1 mm or more and connected to a depth method having a width of 1.5 mm and a depth of 1 mm, for example, may be provided on both side surfaces. .

  As shown in FIGS. 3 (A) and 3 (B), the lighting block construction body 20 of the present embodiment using the support frame 21 includes a plurality of prism glasses 23 and the prism glasses 23 as a light transmitting portion 21d. Are provided with a support frame 21 that is arranged and supported at a portion where the prism 28 is formed, and joint portions 24 that are located between the prism glasses 23 and between the prism glass 23 and the support frame 21. It is installed at the opening with a bolt or the like and functions as a skylight for daylighting.

  As shown in FIG. 4, the prism glass 23 has a square or circular top surface 23a having a planar shape, a side wall surface 23b extending downward from the periphery of the top surface 23a, and a bottom surface 23c having a recessed center. This is a glass block formed in a reverse concave shape as a whole. The prism glass 23 has a dimension of 200 mm on one side × 200 mm on the other side × 50 mm in height, and a pattern 23d that refracts light is formed on the back surface (inner surface) of the top surface 23a.

  As shown in FIGS. 4 and 5, the spacer gasket 22 has a substantially L-shaped cross section that fits around the side wall surface 23b and the bottom surface 23c of the prism glass 23, and one side of the inner surface has a predetermined dimension (for example, It has a substantially square shape (approximately 200 mm), has a predetermined thickness (for example, approximately 20 mm), and is provided with strip protrusions 22c to 22f on the outer peripheral surface of the standing portion 22a, and a strip having a small protruding dimension on the inner peripheral portion. Projection pieces 22g to 22i are formed. In the spacer gasket 22, the strip projection pieces 22 c to 22 f abut against the support frame 21, and the strip projection pieces 22 g to 22 i contact the periphery of the side wall surface 23 b of the prism glass 23 and the horizontal portion 22 b contact the periphery of the bottom surface 23 c. Therefore, liquid such as water does not leak between the prism glass 23 and the spacer gasket 22 or between the spacer gasket 22 and the support frame 21, and the support surface of the support frame 21, the floor of the building, etc. are stained. There is no end. Further, by pressing the prism glass during construction and fitting the spacer combined gasket 22c portion into the two concave groove portions 21c2, the adhesion to the horizontal plate 21b is further improved by the repulsive force.

In addition, even after the construction, even if the joint portion 24 deteriorates and cracks are generated, rainwater from between the prism glass 23 and the spacer combined gasket 22 or between the spacer combined gasket 22 and the horizontal plate 21b and the rib plate 21c. Etc. does not enter and does not leak. The spacer combined gasket 22 requires 30% or more of the side surface dimension from the bottom surface of the prism glass, and 70% of the spacer gasket was used in the examples. The lighting block construction 10 having such a configuration has a weight per unit area of 78 kg / m ² , which is about 40 kg (35% reduction compared to the conventional construction) and lighter than the conventional lighting construction. Is.

  Moreover, since the material of the spacer combined gasket 22 is EPDM (ethylene-propylene-diene monomer rubber) which is an elastic material, it is excellent in weather resistance, water resistance and sealability. The hardness of the rubber constituting the spacer combined gasket 22 is 60 to 80 degrees according to the stipulation of the durometer hardness test of JIS 5756 “Building gasket”. In this embodiment, the hardness is 70 degrees. used.

As shown in FIGS. 3A, 3B, and 4, the support frame 21 has a lattice shape that is substantially the outer dimension of the prism glass 23 in order to support the plurality of prism glasses 23, and is also a spacer. It is L-shaped or inverted T-shaped (may be a cross) so that the strip protrusions 22c, 22d, 22e and 22f of the dual-purpose gasket 22 come into contact with each other. The support frame 21 is made of a metal such as stainless steel having excellent mechanical strength and durability, and has a welded structure. In order to further reduce the weight, a long support portion 21L for supporting a plurality of prism glasses 23 is provided, so that three prism glasses 23 bonded with spacer gaskets 22 can be fitted and aligned. It has become. Such a support frame 21 has a mass per unit area of a conventional cast iron frame of about 67 kg / m ² , whereas the support frame 21 has a mass of about 40 kg / m ² , and the lighting block construction body This greatly contributes to the weight reduction of 20.

  The joint portion 24 has a structure having a backup material 25 and a sealing material 26 made of silicone having a color tone suitable for the surface at the interface with the prism glass 23, the spacer gasket 22 and the support frame 21. The volume occupied by the spacer gasket 22 in the joint portion 24 is about 40%, which is 30% or more. If the volume occupied by the spacer gasket 22 is 100% of the side dimension from the bottom surface of the prism glass, the process of providing the backup material 25 and the sealing material 26 can be simplified, further shortening the construction time and reducing the manufacturing cost. The effect of is remarkable.

The backup material 25 is made of polyethylene closed cell foam. The mass per unit area of the joint portion 24 and the prism glass 23 is 53 kg / m ² in the conventional mortar specification, while it is 38 kg / m ^{2 in} the specification of the present embodiment. This contributes to weight reduction of the structure 20. In addition, by using silicone for the sealing material 26 on the outer surface of the joint portion 24, the weather resistance is good and the color tone can be selected quite freely. It is possible to change the color tone.

  A transparent resin plate 27 made of polycarbonate having a thickness of 2 mm is disposed under the prism glass 23 of the support frame 21. Even if the prism glass 23 is broken, the transparent resin plate 27 prevents the fragments from falling. It has become a structure. By selecting the transparency and color tone of the transparent resin plate 27, it is possible to make the color tone in accordance with the light control or the surrounding color tone, or the color tone conspicuous with respect to the surroundings.

  Next, a method for constructing the daylighting block construction 20 will be described.

  In the production of the support frame 21, first, a flat plate made of stainless steel and having a thickness of 5 mm is cut into a size that fits into the frame body 21 a, and a □ 175 mm × 175 mm size translucent size is formed by laser cutting at a predetermined position of the flat plate. Pierce the part 21d. The punching pitch is 225 mm, and six openings are provided in the short side direction, and ten openings are provided in the long side direction, for a total of 60 openings. The angle members of the frame body 21a, which have been cut to a predetermined length in advance, are joined by butt welding to form a rectangular frame-shaped frame body 21a. The rib plate 21c provided with the concave groove 21c2 on the upper side surface is temporarily attached to the horizontal plate 21b and temporarily fixed by welding, and then fitted into the frame body 21a. When the horizontal plate 21b is fitted, height adjusting liners are put in several places. The end of the rib plate 21c and the angle of the frame 21a are joined. Joining is fillet welding by the TIG welding method, and the fillet size is 5 mm. The main joining of the horizontal plate 21b and the rib plate 21c is performed. Joining is fillet welding by the TIG welding method, and the fillet size is 2 mm.

  As shown in FIG. 4, the prism glass 23 is fitted into the surface having the strip protrusions 22g to 22i of the spacer combined gasket 22 shown in FIG. 5 and bonded with an adhesive (not shown). Next, the prism glass 23 with the spacer gasket 22 fixed thereto is fitted into the long support portion 21 </ b> L of the support frame 21, and the strip protrusion pieces 22 c to 22 f are fixed to the structural material of the support frame 21 and the other prism glass 23. The strip protrusion pieces 22c to 22f of the dual-purpose gasket 22 are pressed and contacted to be aligned. Next, the joint material 24 is filled with a backup material 25, and a sealing material 26 made of silicone having a suitable color tone is filled and solidified from above. When solidified, a lighting block construction 20 as shown in FIG. 4 is completed. The lighting block construction body 20 is formed between the prism glass 23 and the spacer gasket 22, between the spacer gasket 22 and the support frame 21, and in the long support portion 21 </ b> L by the strip protrusions 22 c to 22 i of the spacer gasket 22. Since there is no gap that leaks downward between the spacer-use gaskets 22 fixed to the prism glass 23, the waterproof effect is exhibited immediately after fabrication.

  Next, the daylighting block construction body 20 is carried into the site, and the support frame 21 is attached and fixed to the housing 28 with fixing bolts. After that, when the back-up material 25 is filled between the floor material and the adjacent prism glass 23 of the daylighting block construction body 20, and the sealing material 26 is filled and solidified from above, the solidification is performed as shown in FIGS. Construction of the lighting block construction 20 as shown in B) is completed in a short period of time.

  As shown in FIGS. 6 (A) and 6 (B), a support frame 31 in which the translucent part 31d is a round hole can be used as a support frame constituting the lighting block construction.

  As shown in FIGS. 7A and 7B, a support frame 41 in which the translucent portion 41d is a triangular hole can be used as a support frame constituting the lighting block construction body.

  As shown in FIGS. 8A and 8B, a support frame 51 in which the translucent part 51d is a star-shaped hole can be used as a support frame constituting the daylighting block structure.

  In FIG. 9, the support frame 61 of the block construction 60 for lighting in a present Example is shown. The support frame 61 is for 200 mm × 200 mm × 50 mm prism glass, and is all made of stainless steel. The support frame 61 has a short side of about 1.4 m and a long side of about 2.3 m. The support frame 61 includes a metal frame 61a that surrounds the outer periphery of the group of arranged prism glasses 63, a metal horizontal plate 61b in which a translucent portion 61d is formed at a portion where the prism glass 63 is disposed, A metal rib plate (vertical plate) 61c that is disposed in one direction between the prism glasses 63 and extends between opposing members of the frame body 61 is joined. The frame 61a of the support frame 61 uses L-shaped steel 75 mm × 60 mm × 6 mm, the rib plate 61c uses a flat bar 35 mm × 5 mm, and the horizontal plate 21b uses a 5 mm plate. Further, in the support frame 61, SUS304 stainless steel φ5.5 mm reinforcing bars 61f are arranged in two rows in a direction orthogonal to the vertical plate 61c. It is joined to the surface 61a1 by arc welding.

  Moreover, as shown in FIGS. 10A and 10B, the lighting block construction 60 using the support frame 61 has a plurality of prism glasses 63 and a prism glass 63 formed with a light transmitting portion 61d. It is provided with a support frame 61 that is arranged and supported at a part, and a joint portion 64 that is positioned between the prism glasses 63 and between the prism glass 63 and the support frame 61. It functions as a skylight for daylighting. Here, if the support frame 61 is only a support frame member having a T-shaped cross section composed of the horizontal plate 61b and the rib plate 61c, the wrinkles and twists generated in the long side direction until the joint mortar is cured. However, as shown in FIGS. 10A and 10B, the reinforcing bar 61f is arranged in a direction orthogonal to the rib plate 61c, and the rib plate 61c By joining the upper end and the vertical surface 61a1 inside the frame 61a by arc welding, the cross-sectional performance in the long side direction is improved and the strength is improved. As a result, the amount of wrinkles and torsion is reduced and no problems occur, and the effect of improving the strength can be obtained with respect to the upward blowing force.

  Further, as shown in FIG. 11A, the support frame 21 of the lighting block construction body 20 is grounded and fixed to the housing 28 via the anchor member 28a on the outer horizontal plate 21a1 of the frame body 21a. As shown in FIG. 11B, when the support frame 71 having no outer bottom horizontal plate is produced and the anchor piece member 78a is used, the material cost and weight of the support frame 71 can be reduced. Further, when connecting and arranging the lighting block construction bodies, as shown in FIG. 11C, when the support frame 81 and the support frame 81 are continuous, they project from the outer bottom portions of the frame bodies 81a. By devising the dimensions and position of the horizontal plate 81a1 and arranging it in a staggered manner, the connection interval between the lighting block structures can be reduced in the direction indicated by the arrow in FIG. The design of the wall surface is improved.

  In the above embodiment, the prism glass 23 has a side of 200 mm × the other side of 200 mm × a height of 50 mm. However, a lighting block construction is produced using a side of 120 mm and a height of 40 mm. May be.
