Description

  The present invention relates to a shoji in which a multi-layer glass is mounted on a shoji frame, and a setting block used for placing the lower end of the multi-layer glass in the shoji.

  Conventionally, in order to enhance the heat insulation of the shoji attached to the window of the house, a sealing material such as a sealing material or a desiccant is provided between the peripheral edges of the pair of glass plates arranged with a gap in the indoor and outdoor directions. Intercalated double glazing is used. However, a shoji using such a double-glazed glass may cause dew condensation on the glass plate surface inside the double-glazed glass.

  The cause of such condensation is that water stays in the lower glass fitted with the multilayer glass lower end, the sealing material at the lower end of the multilayer glass deteriorates, and the sealing material and the glass plate It is mentioned that peeling occurs between these. As shown in FIG. 10, it is common practice to place the lower end of the multi-layer glass (11) on a setting block (70) disposed in the lower glass (3). It has been confirmed that peeling between the dressing (15) and the glass plates (12) and (13) occurs at the place where the setting block (70) is disposed. This is because the lower surface of the sealing material (15) of the multilayer glass (11) and the upper surface of the setting block (70) are in contact with each other, so that the weight of the multilayer glass (11) is received. Pressure is applied to the sealing material (15) by the reaction force of the setting block (70), which causes shear stress at the interface between the sealing material (15) and the glass plates (12) (13). It depends. Another factor is that the deterioration of the sealing material (15) is promoted by moisture remaining for a long time due to capillary action at the interface between the sealing material (15) and the setting block (70). it is conceivable that.

  On the other hand, in the configuration shown in FIG. 6 of Patent Document 1, another member is interposed between the multilayer glass and the setting block, and the sealing material is provided slightly above the lower end of the multilayer glass. Therefore, the sealing material and the setting block are not in contact with each other. However, in the configuration of Patent Document 1, a part of the sealing material that is shifted upward is visible from the outside through the glass plate on the upper side of the upper end of the lower collar, so that there is a disadvantage that the appearance is remarkably impaired. .

  Moreover, in patent document 2, the contact of a sealing material and a setting block can be avoided now by interposing the bottom part of a glazing channel between a sealing material and a setting block. However, in the configuration of Patent Document 2, water is likely to stay between the glazing channel and the setting block at the portion where the glazing channel is interposed between the sealing material and the setting block. It was necessary to match the position of the formed opening to the position where the setting block was placed, and the workability was poor by the amount of such alignment.

  On the other hand, a concave setting block with a concave portion on the top surface that prevents the sealing material and the setting block from contacting each other is known, but even such a setting block has a shallow groove depth. The water between the sealing material and the setting block remained as a water film, and the water was not drainable so that the water could be discharged. In addition, depending on the specifications of the multilayer glass, such a concave setting block may not be able to avoid contact with the sealing material depending on the thickness of the glass sheet or sealing material of the multilayer glass. It was necessary to use various setting blocks with different shapes.

  Therefore, the present invention eliminates the above problems and can prevent deterioration of the sealing material by improving drainage between the sealing material at the lower end of the multilayer glass and the setting block. It is an object of the present invention to provide a setting block that can ensure good drainage in response to a shoji screen using a glass and a multilayer glass having different specifications.

In order to solve the above-mentioned problems, the shoji using the setting block in the present invention has a double-layer glass mounted on the shoji frame so that the lower ends of the pair of glass plates in the indoor and outdoor directions are placed on the setting block. The setting block includes a main body portion having a pair of mounting surfaces in the indoor / outdoor direction in which the lower ends of the pair of glass plates are directly mounted, and a hard body provided below the main body portion. A plate-like base portion made of resin, and avoiding contact with the sealing material interposed between the pair of glass plate peripheral portions between the pair of mounting surfaces of the setting block. A concave groove for drainage is formed, and the main body portion is composed of a pair of indoor and outdoor mounting projections having the above-described mounting surface rising from the base portion so as to sandwich the concave groove, and at least one mounting On the side wall of the groove side of the projection, wherein the disconnection unit be disconnected along the notch to expand the width between the pair of mounting surface is provided.

Furthermore, the depth of the concave groove for drainage is at least 3 mm or more, preferably 4 mm or more.

  In addition, a glazing gasket is interposed between each glass plate and the shoji frame outside the shoji frame in the pair of glass plates in the thickness direction.

Further, the setting block according to the present invention is one in which the lower ends of the pair of glass plates in the indoor / outdoor direction in the multi-layer glass mounted on the shoji frame are placed, and the lower ends of the pair of glass plates are directly placed respectively. And a plate-like base portion made of a hard resin provided on the lower side of the main body portion, and the pair of mounting surfaces between the pair of mounting surfaces. The drainage ditch is formed so as to avoid contact with the sealing material interposed between the peripheral edges of the glass plate, and the main body rises from the base so as to sandwich the ditch It comprises a pair of indoor and outdoor mounting projections having mounting surfaces, and at least one of the mounting projections has a notch so as to increase the width between the pair of mounting surfaces on the side wall portion on the concave groove side. There is a separation part that is cut along And wherein the are.

Further, the pair of mounting projections have substantially the same shape, and the widths of the upper surfaces of the separating portions of the mounting projections are substantially equal in the thickness direction of the shoji frame.

In addition, the pair of mounting projections includes a protruding portion that protrudes toward the concave groove so as to increase the adhesion area with the base portion.

  According to this invention, the concave groove for drainage is formed on the upper surface of the setting block on which the glass plate of the multilayer glass is placed so as to avoid contact with the sealing material interposed between the peripheral portions of the glass plate. Since it is formed, water that has entered between the setting block and the sealing material is discharged through the concave groove.

  That is, even if the multi-layer glass is placed directly on the setting block, the setting block and the sealing material do not come into contact with each other, so that the bottom of the glazing channel is interposed between the setting block and the multi-layer glass as in the past. There is no need to make it necessary, and the alignment as described above is not necessary, and deterioration of workability can be avoided.

  As described above, since the sealing material does not contact the setting block, it is possible to prevent deterioration of the sealing material due to water retention, and the sealing material is peeled off from the glass plate due to the pressure from the setting block. There is nothing. Therefore, it is possible to prevent dew condensation from occurring on the glass plate surface on the inner side of the multilayer glass.

  Moreover, since the depth of the ditch | groove for drainage shall be at least 3 mm or more, desirably 4 mm or more, since the depth of the grade which water does not retain as a water film is ensured, drainage property is made especially favorable. Can do.

Furthermore, the setting projection of the setting block is provided with a cut-off portion that is cut along the notch in the side wall portion on the groove side, so that the groove is sandwiched by cutting the cut- off portion as necessary. The width between the mounting surfaces on both sides can be increased. Therefore, it is possible to avoid contact between the sealing material and the setting block according to the specifications of the multi-layer glass placed on the setting block, and it is not necessary to use various setting blocks according to the specifications of the multi-layer glass. That's it.

  In addition, the mounting projections on both sides have substantially the same shape, and the widths of the upper surfaces of the cut-off portions on both sides are substantially equal. For example, as a fire door specification or a crime prevention specification, a thick glass plate such as netted glass or laminated glass And, in the case of using in combination with a normal thickness glass plate, either of the specification that the glass plate with a large thickness is installed on the indoor side and the case where the glass plate is installed on the outdoor side, The same applies to the case of using the double-glazed glass having the specifications.

  Furthermore, since the base part is made of hard resin, high strength can be secured even if the base part is formed thin, and it is difficult to deform even if the bottom of the setting block is uneven. The glass plate can be supported stably.

  Furthermore, since the mounting projections on both sides sandwiching the concave groove are provided with a protruding portion that protrudes toward the concave groove so as to increase the bonding area with the base portion, the bonding between the base portion and the main body portion is possible. You can strengthen your power.

  In addition, since the glazing gasket is interposed between the glass plate and the shoji frame on the outer side in the thickness direction of the shoji frame in the pair of glass plates, the attachment state of the glass plate to the shoji frame can be stabilized.

  Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. In FIG. 1 and FIG. 2, (1) is a shoji in which a double-glazed glass (11) is mounted on a metal shoji frame (2), for example. The multi-layer glass (11) is attached to the shoji frame (2) in a state where the glazing gasket (25) is wound around the peripheral edge thereof.

  In addition, as shown in FIG. 2, a plurality of setting blocks (40) are arranged in advance in the lower arm (3) of the shoji frame (2) at intervals in the length direction of the lower arm (3). The double-glazed glass (11) is mounted on the lower glass (3) so that the lower ends of a pair of glass plates (12) and (13) in the indoor and outdoor direction of the double-glazed glass (11) are placed on the setting block (40). Is done.

  The lower frame (3) of the shoji frame (2) is provided with a mounting groove (7) having an approximately U-shaped cross section that opens upward, and the lower end of the multilayer glass (11) is provided in the mounting groove (7). It is designed to be fitted. A protruding piece (8) protruding toward the center in the thickness direction of the shoji frame (2) is provided at the upper end of the side wall of the mounting groove (7). Further, at the bottom of the mounting groove (7), a drain hole (10) for discharging water that has entered the mounting groove (7) to the lower side of the shoji (1) is provided at an appropriate place.

  Multi-layer glass (11) is a pair of glass plates (12) (13) arranged with a gap in the indoor and outdoor direction, and sealing interposed between the peripheral edges of the glass plates (12) (13) It consists of wood (15). As shown in FIG. 3, the sealing material (15) is formed in a hollow shape and contains a desiccant (17) inside, for example, a metal spacer (16) and a pair of the spacer (16) and the spacer (16). Primary sealing material (18) (18) filled in the gap between the glass plates (12) and (13), and the multilayer glass (11) of these spacers (16) and primary sealing materials (18) (18) And a secondary sealing material (19) filled in a gap between the glass plates (12) and (13) on the peripheral side.

  The glazing gasket (25) is formed, for example, by extrusion molding so as to have a substantially U-shaped cross section.In the wrapping portion around the lower edge of the multilayer glass (11), a pair of side walls (26) (26 ) And a bottom portion (27) straddling between the lower ends of the side wall portions (26) and (26).

  In a state where the glazing gasket (25) is wound around the multilayer glass (11), each end face except the lower end face of the multilayer glass (11) is covered with the glazing gasket (25), and the multilayer glass (11) The lower end surface is exposed. The glazing gasket (25) is made of synthetic resin, rubber or other polymer material. In particular, it is desirable to use a soft polymer material as the material of the glazing gasket (25), so that the winding work around the multilayer glass (11) can be easily performed.

  As shown in FIG. 3, the upper end of the glazing gasket (25), the side walls (26) and (26) has engaging recesses (28) and (28) that open toward the outside in the thickness direction of the shoji frame (2). The engaging recess (28) is formed so as to engage with the protruding piece (8) provided in the mounting groove (7) of the shoji frame (2). Further, the upper end of the side wall portion (26) of the glazing gasket (25) has an upper pressing piece (29) extending obliquely upward toward the center side in the thickness direction of the shoji frame (2), and also in the center in the thickness direction. A lower pressing piece (30) extending obliquely downward toward the side is provided. The pair of upper and lower pressing pieces (29) and (30) are in contact with the surfaces of the glass plates (12) and (13) in the mounted state. Thus, in a state in which the double-glazed glass (11) is mounted on the shoji frame (2), the glazing gasket (25) is located outside the shoji frame (2) in the thickness direction of the pair of glass plates (12) and (13). The glass plates (12) (13) and the shoji frame (2) are interposed.

  The setting block (40) includes a main body (41) having a pair of placement surfaces (45) and (46) in the indoor and outdoor directions, and a plate-like base (42) provided below the main body (41). ). The lower end of the indoor glass plate (12) is directly placed on the indoor placement surface (45), and the lower end of the outdoor glass plate (13) is directly placed on the outdoor placement surface (46). It is supposed to be placed.

  And on the upper surface of the setting block (40), between the pair of mounting surfaces (45) (46), the sealing material (15) interposed between the peripheral portions of the glass plates (12) (13). A drain groove (50) for avoiding contact is formed. The drainage groove (50) is arranged along the length of the lower rod (3) in the mounted state, and between the setting block (40) and the sealing material (15). Water that has entered is drained through the ditch (50).

  Accordingly, since water does not stay between the setting block (40) and the sealing material (15) for a long time, the deterioration of the sealing material (15) can be prevented, and the inner side of the multilayer glass (11) can be prevented. It is possible to prevent condensation on the surface of the glass plates (12) and (13). In addition, the drainage from the ditch | groove (50) is discharged | emitted below the shoji (1) from the drain hole (10) of the lower rod (3).

  The depth of the concave groove (50), that is, the height from the upper surface of the base portion (42) to the mounting surfaces (45) and (46) is at least 3 mm or more, preferably 4 mm or more. In this way, the depth of the groove (50) is such that a water film that stays between the setting block (40) and the sealing material (15) is not formed, so that good drainage properties Can be secured.

  The main body (41) is composed of a pair of mounting projections (43) (43) rising from the base (42) so as to sandwich the concave groove (50). The mounting projections (43) and (43) are formed along the length direction of the lower collar (3) at both ends of the upper surface of the base portion (42) in the indoor / outdoor direction. The upper surfaces of the mounting projections (43) and (43) are the mounting surfaces (45) and (46).

  Further, the mounting projections (43) and (43) include projecting portions (49) and (49) projecting toward the concave groove (50) so as to increase the adhesion area with the base portion (42). . That is, the pair of mounting protrusions (43) and (43) are each formed in a substantially L-shaped cross section, and the mounting protrusions (43) and (43) on both sides have substantially the same shape. However, the overhang portions (49) and (49) are not necessarily provided.

As the material of the main body (41), for example, an olefin-based synthetic resin is used, but is not particularly limited thereto, for example, chloroprene rubber, silicon rubber or other polymer material, or a combination thereof. A composite material may be used. On the other hand, the base part (42) is made of hard resin harder than the main body part (41). Specifically, for example, polypropylene resin is preferably used as the material of the base portion (42), but is not particularly limited thereto. The setting block (40) is integrally formed by so-called two-color extrusion molding using two kinds of materials, ie, the main body portion (41) and the base portion (42) .

  As shown in FIG. 4, the width (L1) in the indoor / outdoor direction of the setting block (40) is, for example, 24 mm, and the standard specification multilayer glass (11) in which the thickness (M1) is, for example, 20 mm. Can be placed in a relaxed manner. In addition, the setting block (40) has a width (L2) between the mounting surfaces (45) and (46) on both sides of, for example, 14 mm, and even if a standard specification multilayer glass (11) is mounted, Since the width of the sealing material (15) of the multi-layer glass (11) is wider or approximately the same, the mounting surface (45) (46) and the sealing material (15) do not come into contact with each other. It has become.

  Further, as shown in FIG. 5, the placement projection (43) has a center in the thickness direction of the shoji frame (2) in the glass plates (12) and (13) placed on the placement projection (43). Depending on the position of the side edge, the position of the upper end of the side wall on the concave groove (50) side of the mounting projection (43) is changed so that the fixed portion (47) (78) on the side wall side is changed. A notch (55) is provided for separating the.

  The notch (55) is formed in a substantially L-shaped cross section, and has a vertical portion (56) that hangs down from the placement surfaces (45) and (46) of the placement projections (43) and (43), as well as its placement. It consists of a horizontal portion (57) extending substantially horizontally from the side wall on the concave groove (50) side of the placement projections (43) and (43) toward the outside in the thickness direction of the shoji frame (2). The horizontal portion (57) of the notch (55) is formed to be continuous with the upper surface of the overhang portion (49).

  The notch (55) is formed simultaneously with the extrusion of the setting block (40). Further, it is not always necessary to provide notches (55) and (55) on the mounting projections (43) and (43) on both sides, and it is possible to provide notches (55) only on one of the mounting projections (43). Be good.

  The cut-off portions (47) and (48) cut off along the notches (55) and (55) from the mounting protrusions (43) and (43) can be easily peeled off without using tools or the like. Yes. And the position of the upper end of the side wall on the side of the groove (50) in the mounting projection (43) on the peeled side is determined by peeling off the cut-off portions (47) and (48). Accordingly, the width (L2) between the mounting surfaces (45) and (46) on both sides is enlarged.

  The shapes of the cut-off portions (47) and (48) are rectangular in cross section. Further, the widths of the upper surfaces of the cut-off portions (47) and (48) on both sides are substantially equal in the thickness direction of the shoji frame (2). In addition, as a dimension of the thickness direction of the shoji frame (2), the width of the mounting surfaces (45) and (46) including the upper surfaces of the separation portions (47) and (48) is, for example, 5 mm, and the separation portions (47) ( 48) The width of the upper surface is 2 mm, for example.

  FIG. 6 shows a multi-layer glass (11) that is mainly used as a fire door specification or a crime prevention specification in a general area. In this multi-layer glass (11), as a glass plate (12) on the indoor side, A glass plate having a larger thickness than usual, such as glass and laminated glass, is used. The thickness (M2) of the multi-layer glass (11) in this special specification is equivalent to the thickness (M1) of the standard multi-layer glass (11) shown in FIG. Is bigger than. Specifically, the thickness (M2) of the special specification multilayer glass (11) is, for example, 24 mm, and is substantially equal to the width (L1) of the setting block (40). Note that the width of the sealing material (15) is substantially equal in both specifications of FIGS.

  When the special specification multilayer glass (11) shown in FIG. 6 is placed on the setting block (40), the thickness of the indoor glass plate (12) is larger than the standard multilayer glass (11). Therefore, the sealing material (15) is arranged on the outdoor side as compared with the case of the standard multilayer glass (11). Therefore, if construction is performed without separating the separation portions (47) and (48), the placement surface (46) on the outdoor side comes into contact with the sealing material (15). Therefore, by separating the separation part (48) on the outdoor side in advance, the width (L2) between the mounting surfaces (45) and (46) on both sides can be expanded, and the setting block (40) and the sealing are sealed. Contact with the material (15) can be avoided.

  On the other hand, FIG. 7 shows a multi-layer glass (11) used mainly as a fire door specification or a crime prevention specification in a cold region. In this multi-layer glass (11), an outdoor glass plate (13) is shown. It is a glass plate with a large thickness, such as netted glass or laminated glass. In this case as well, by separating the indoor side separation portion (47) in advance, the width (L2) between the mounting surfaces (45) and (46) on both sides can be increased, and the setting block (40 ) And the sealing material (15) can be avoided. In addition, when using the multilayer glass (11) having a relatively large thickness as shown in FIGS. 6 and 7, as the glazing gasket (25), a glass having a relatively small thickness of the side wall (26) should be used. To do.

  8 and 9 show a setting block (40) according to another embodiment of the present invention. In this embodiment, a plurality of narrow grooves (60), (60) are formed in the length direction of the lower collar (3) on the upper surface of the base portion (41) between the mounting projections (43), (43) on both sides. It is provided along. As described above, by providing the narrow grooves (60), (60),... At the bottom of the drain groove (50), drainage of the groove (50) can be further promoted.

  In this embodiment, three narrow grooves (60), (60), which have an inverted triangular cross section, are formed as a whole by forming protrusions having a cross-sectional angle between the narrow grooves (60), (60),. It is formed in a wave shape. Thus, by forming the wavy narrow grooves (60), (60) ... at the bottom of the groove (50), water is less likely to stay than when the bottom of the groove (50) is a horizontal plane. ing. Moreover, since the outer side wall surfaces of the narrow grooves (60), (60) on the outer side in the thickness direction of the shoji frame (2) are connected to the upper surfaces of the overhang portions (49), (49), the overhang portions (49) ( 49) The water on the upper surface is easy to flow into the narrow grooves (60) (60). However, the shape of the narrow grooves (60) (60) is not particularly limited.

  The present invention is not limited to the above embodiment, and it is needless to say that many modifications and changes can be made to the above embodiment within the scope of the present invention. For example, in the above embodiment, the case where the lower end portion of the multi-layer glass (11) is attached to the lower arm (3) of the shoji frame (2) has been described. It can also be applied to.
