In the present embodiment, the plurality of drainage structures 8 may have a shape in which the length of the drainage block 81 in the finding direction and the direction in the finding direction are different (the left and right are reversed shapes). However, the basic structure of the drainage structure 8 and the configuration of attachment to the glass groove are the same. Therefore, the description of the drainage structure 8 described in the present embodiment can be applied to the structure of the plurality of drainage structures 8 and the configuration of attachment to the glass groove.

First, the shape of the inner peripheral surface of the glass groove 312a of the first mullion member 31 on which the drainage structure 8 is arranged will be described. As shown in FIGS. 6 and 7, the shape of the inner peripheral surface of the glass groove 312a of the first mullion member 31 is a virtual plane M which is a vertical cross section extending in the finding direction at the center of the glass groove 312a in the prospective direction. On the other hand, it has a symmetrical shape.

As shown in FIG. 7, the shape of the inner peripheral surface of the glass groove 312a of the first mullion member 31 is formed into a simple shape. The reason for making the shape of the inner peripheral surface of the glass groove 312a simple is that the shape of the drainage structure 8 housed in the glass groove 312a of the first mullion member 31 is made simple, so that the shape is complicated. This is to improve the watertightness between the glass groove 312a of the first mullion member 31 and the drainage structure 8 rather than stopping the water in the glass groove.

Specifically, as shown in FIG. 7, the shape of the inner peripheral surface of the glass groove 312a of the first mullion member 31 is in the horizontal view (horizontal plane (plane in the direction orthogonal to the direction in which the mullion 25 extends)). When the cut cross section is viewed in the direction in which the glass groove 312a extends), it is formed in a curved shape having a concave shape on the opposite side of the skirting portion 22 in the finding direction. In other words, the shape of the inner peripheral surface of the glass groove 312a of the first mullion member 31 is the tip of the drainage structure 8 in the insertion direction of the drainage structure 8 into the glass groove 312a when the drainage structure 8 is housed. It is a curved shape with a rounded shape having a concave side on which the side (the side opposite to the widthhead portion 22 in the finding direction) is arranged.

The inner peripheral surface of the glass groove 312a of the first mullion member 31 includes a prospective surface 30a extending in the prospective direction, a pair of finding surfaces 30b and 30b extending in the finding direction, and both ends of the prospective surface 30a in the prospective direction. It has a pair of curved surfaces 30c that connect one end of the finding surface 30b via a protruding locking portion 30d (described later). Inner circumference of glass groove 312a passing through the finding surface 30b, the protruding locking portion 30d (described later), the curved surface 30c, the finding surface 30b, the curved surface 30c, the protruding locking portion 30d (described later), and the finding surface 30b in this order. The shape of the surface is formed as a U-shaped curved surface as a whole.

Further, a pair of projecting locking portions 30d and 30d extending in the vertical direction along the direction in which the glass groove 312a extends are formed on the inner peripheral surface of the glass groove 312a of the first mullion member 31. The pair of projecting locking portions 30d, 30d project toward the inside of the glass groove 312a between the found surface 30b of the glass groove 312a and the curved surface 30c, and move up and down along the glass groove 312a of the first mullion member 31. Extend in the direction. When the glass 62a is not attached to the glass groove 312a of the first mullion member 31, a cover member 9 that closes the glass groove 312a is attached to the pair of protruding locking portions 30d and 30d, as shown in FIG. ..

As shown in FIG. 10, the cover member 9 is formed in a shape symmetrical with respect to the virtual plane M which is a vertical cross section extending in the finding direction at the center of the cover member 9 in the prospective direction. The cover member 9 extends from both the closing surface plate 91 that closes the glass groove 312a of the first mullion member 31 and both ends of the closing surface plate 91 in the finding direction, and the finding surface of the glass groove 312a of the first mullion member 31. It has a pair of side plates 92 and 92 arranged along 30b, and a protrusion 93 formed at an end portion of each of the side plates 92 opposite to the closing surface plate 91.

As a result, when the glass 62a is not attached to the glass groove 312a of the first mullion member 31, the pair of protrusions 93 and 93 of the cover member 9 and the cover member 9 are attached to the glass groove 312a of the first mullion member 31. By locking the pair of projecting locking portions 30d and 30d, the cover member 9 can be attached to the glass groove 312a of the first mullion member 31 to close the glass groove 312a of the first mullion member 31. ..

As shown in FIG. 7, the pair of projecting locking portions 30d and 30d only slightly protrude from the inner peripheral surface of the glass groove 312a of the first mullion member 31, and thus the found surface of the glass groove 312a. Even if it is arranged between the 30b and the curved surface 30c, the configuration in which the inner peripheral surface of the glass groove 312a of the first mullion member 31 is curved is ensured. Further, the pair of projecting locking portions 30d and 30d are formed so as to be curved and gently project, and have a simple curved shape of the inner peripheral surface of the glass groove 312a of the first mullion member 31. It is formed in a shape that does not interfere with.

As described above, by making the shape of the inner peripheral surface of the glass groove 312a of the first mullion member 31 a simple shape, the shape of the drainage structure 8 that stops water in the glass groove 312a of the first mullion member 31. Can be made into a simple shape. Therefore, the watertightness between the glass groove 312a of the first mullion member 31 and the drainage structure 8 can be improved as compared with the water blocking of the glass groove having a complicated shape.

The drainage structure 8 is housed in the glass groove 312a of the first mullion member 31. As shown in FIGS. 8A and 8B, the drainage structure 8 includes a drainage block 81, a foaming material 82, a first water-swelling water-stopping material 83, and a second water-swelling water-stopping material. The material 84 is provided. The drainage block is a member made of resin and is formed in a block shape. The drainage block 81 has a block body 811 and a pair of protrusions 812 and 812.

The block body 811 is formed in a flat plate-like block shape having a certain thickness. When the drainage structure 8 is housed in the glass groove 312a of the first mullion member 31, the block body 811 has an outer peripheral surface shape corresponding to the inner peripheral surface of the glass groove 312a of the first mullion member 31. It is formed in a shape corresponding to the shape of the inner peripheral surface of the glass groove 312a of the first mullion member 31 described above.

As shown in FIG. 9, the block main body 811 has a top surface (upper side) of the glass groove 222a of the xylem portion 22 in a state where the drainage structure 8 is attached to the glass groove 312a of the first mullion member 31.

Specifically, the shape of the outer peripheral surface of the block body 811 is when a cross section cut in a horizontal plane (a plane in a direction orthogonal to the direction in which the square 25 extends) is viewed in a direction in which the glass groove 312a extends. ), The tip side of the drainage structure 8 in the insertion direction into the glass groove 312a when the drainage structure 8 is housed on the outer peripheral surface (the side opposite to the skirting portion 22 in the finding direction) has a convex radius. It is a curved surface with a rounded shape.

As shown in FIG. 8, the outer peripheral surface of the block body 811 has a base end surface portion 81a extending in the prospective direction and a tip end surface portion 81c extending in the prospective direction on the side opposite to the base end surface portion 81a of the block body 811 in the finding direction. It has a pair of extending side surface portions 81b, 81b, and a pair of block curved surfaces 81d, 81d connecting the pair of side surface portions 81b, 81b and the tip surface portion 81c via a recess 81e (described later). The shape of the outer peripheral surface of the block body 811 passing through the side surface portion 81b, the concave portion 81e (described later), the block curved surface 81d, the tip surface portion 81c, the block curved surface 81d, the concave portion 81e (described later), and the side surface portion 81b in this order is U-shaped as a whole. It is formed in the shape of a curved surface.

As shown in FIGS. 6 and 7, a pair of recesses 81e and 81e are formed on the outer peripheral surface of the block body 811. The pair of recesses 81e and 81e are formed by being recessed from the outer peripheral surface between the side surface portion 81b and the block curved surface 81d on the outer peripheral surface of the block body 811 and extend in the thickness direction. The pair of recesses 81e and 81e have a shape that avoids the pair of protruding locking portions 30d and 30d of the glass groove 312a of the first mullion member 31 when the drainage structure 8 is housed in the first mullion member 31. Is formed in.

Since the pair of recesses 81e and 81e are slightly recessed from the outer peripheral surface of the block body 811, the outer peripheral surface of the block body 811 has a curved surface even if it is arranged between the side surface portion 81b and the block curved surface 81d. The configuration is secured. Further, the pair of recesses 81e and 81e are formed so as to be gently recessed with a radius, and are formed in a shape that does not interfere with the simple curved shape of the outer peripheral surface of the block body 811.

As shown in FIG. 6, the base end surface portion 81a is located on the same plane as the inner side surface 31a extending in the vertical direction of the first mullion member 31 when the drainage structure 8 is housed in the glass groove 312a. The pair of side surface portions 81b, 81b face the pair of finding surfaces 30b, 30b on the inner peripheral surface of the glass groove 312a. The tip surface portion 81c faces the prospective surface 30a of the inner peripheral surface of the glass groove 312a. The pair of block curved surfaces 81d and 81d face the pair of curved surfaces 30c and 30c on the inner peripheral surface of the glass groove 312a. The pair of recesses 81e and 81e face the pair of protruding locking portions 30d and 30d on the inner peripheral surface of the glass groove 312a.

As described above, the shape of the block main body 811 can be made a simple shape by corresponding to the shape of the inner peripheral surface of the glass groove 312a of the first mullion member 31. Therefore, the simple-shaped glass groove 312a can be stopped by the drainage structure 8 having the simple-shaped block body 811. As a result, the watertightness between the glass groove 312a of the first mullion member 31 and the drainage structure 8 can be improved rather than stopping the water in the glass groove having a complicated shape.

As shown in FIG. 8, the pair of protrusions 812 and 812 are provided on the upper surface and the lower surface at the tip end portion of the block body 811 on the tip end surface portion 81c side.

In the present embodiment, the first water-swellable water blocking material 83 is attached to the outer peripheral surface of the foaming material 82 via an adhesive.

The second water-swellable water blocking material 84 is formed in the form of a thin sheet, and is provided on the upper surface and the lower surface of the drainage block 81. In the present embodiment, the second water-swellable water blocking material 84 is formed in the same shape as the upper surface and the lower surface of the drainage block 81, and is formed over the entire upper surface and lower surface of the drainage block 81 via an adhesive. It is pasted.

In the present embodiment, the second water-swelling water blocking material 84 is provided on both the upper surface and the lower surface of the drainage block 81, so that the structure is symmetrical in the vertical direction. As a result, the drainage block 8 can be used in either the vertical direction with respect to the second water-swellable water blocking material 84. The second water-swelling water blocking material 84 may not be provided on both the upper surface and the lower surface of the drainage block 81, but may be provided only on the upper surface of the drainage block 81, for example.

The first water-swellable water-stopping material 83 and the second water-swelling water-stopping material 84 are made of, for example, polyolphin as a base material, have an absorbing layer on the surface, and have an acrylic-based surface on the surface opposite to the surface. An adhesive layer is formed. The absorption layer is formed by using, for example, a super absorber polymer (SAP). The polymer absorber is also called a super absorbent polymer, and absorbs water that has penetrated into the first water-swellable water-stopping material 83 and the first water-swelling water-stopping material 83, changes it into a gel, and expands it. As a result, the first water-swelling water-stopping material 83 and the first water-swelling water-stopping material 83 close the gap between the foaming material 82 and the glass groove 312a of the first mullion member 31 to stop water, and water is stopped. Leakage and inundation can be prevented.

As the first water-swellable water-stopping material 83 and the second water-swelling water-stopping material 84, for example, the total thickness is 280 μm, the thickness of the absorption layer is 50 μm, the thickness of the base material layer is 80 μm, and the thickness of the adhesive layer is Those having a layer structure of 150 μm can be used.

Next, an attachment method for attaching the drainage structure 8 to the glass groove 312a of the first mullion member 31 will be described.
First, as shown in FIGS. 8A and 8B, the foaming material 82 is attached to the outer peripheral surface of the drainage block 81. Then, the first water-swelling water blocking material 83 is attached to the outer peripheral surface of the foam material 82. Then, the second water swelling water blocking material 84 is attached to the upper surface of the drainage block 81.

As shown in FIG. 7, the drainage structure 8 configured in this way is located on the side of the glass groove 312a of the first mullion member 31, and the tip end side of the drainage block 81 is the glass of the first mullion member 31. Arrange so that it faces the groove 312a.

Next, the drainage block 81 is pushed into the glass groove 312a of the first mullion member 31 in order from the tip side to be press-fitted. As a result, the foam material 82 in the drainage structure 8 is inserted into the glass groove 312a of the first mullion member 31 in a compressed state. In the drainage structure 8, since the foam material 82 has flexibility, the outer peripheral surface of the foam material 82 follows the shape of the glass groove 312a of the first mullion member 31 by the elastic recovery force, and the outer peripheral surface of the foam material 82 becomes the first mullion. It is press-fitted into the glass groove 312a of the member 31 while being pressed.

Here, the shape of the inner peripheral surface of the glass groove 312a of the first mullion member 31 is symmetrical with respect to the virtual plane M which is a vertical cross section extending in the finding direction at the center of the glass groove 312a in the prospective direction. is there. Further, the shape of the outer peripheral surface of the block body 811 of the drainage block 81 is symmetrical with respect to the virtual plane M which is a vertical cross section extending in the finding direction at the center of the block body 811 in the prospective direction.

Therefore, when the drainage block 81 is press-fitted into the glass groove 312a of the first mullion member 31, the drainage block 81 can be press-fitted so that the pressure is evenly applied on both sides of the drainage block 81 in the expected direction. The gap between the first mullion member 31 and the glass groove 312a can be further closed. Therefore, the watertightness between the drainage block 81 and the glass groove 312a of the first mullion member 31 can be further improved.

Further, a pair of protrusions 812 and 812 are provided on the tip end side of the drainage block 81. Therefore, the tip surfaces 812a of the pair of protrusions 812 and 812 are arranged corresponding to the prospective surface 30a of the glass groove 312a of the first mullion member 31 and are arranged on the prospective surface 30a of the glass groove 312a of the first mullion member 31. Placed in contact or close proximity. As a result, the block body 811 is positioned with respect to the prospective surface 30a of the glass groove 312a so that the block body 811 is not arranged so as to be tilted with respect to the horizontal direction. Therefore, the drainage structure 8 is stably arranged in the glass groove 312a of the first mullion member 31 so as not to be tilted. The watertightness between the drainage block 81 and the glass groove 312a of the first mullion member 31 can be further improved.

Next, as shown in FIG. 6, with the water blocking sheet 72 arranged between the drainage structure 8 and the first mullion member 31 and the side end surface of the xylem portion 22, the side end surface of the cullion portion 22 Is attached to the first mullion member 31. Here, as shown in FIG. 9, the upper surface of the block body 811 is the bottom surface of the glass groove 222a of the xylem portion 22 in a state where the drainage structure 8 is attached to the glass groove 312a of the first mullion member 31. It is arranged so as to be located on the same plane as the surface facing upward).

In this state, as shown in FIG. 7, from the side of the first mullion member 31 opposite to the xylem portion 22, the through hole 31b of the first mullion member 31, the drainage structure 8, the water stop sheet 72, and the width. The xylem 22 is passed through the screw 73 in this order, and the first mullion member 31, the drainage structure 8, the water blocking sheet 72, and the xylem 22 are fastened together with the screw 73. As a result, as shown in FIG. 6, the drainage structure 8 is fixed in the glass groove 312a of the first mullion member 31. In the present embodiment, in the foaming material 82 and the first water-swelling water blocking material 83 in the drainage structure 8, through holes are formed in advance at the locations where the screws 73 penetrate.
It is not necessary that a through hole is formed in the foaming material 82 or the first water-swelling water blocking material 83 before the screw 73 is fastened together. That is, the through hole may be formed by penetrating the screw 73 from the state where the through hole is not formed in the foaming material 82 or the first water-swellable water blocking material 83.

In this way, the drainage structure 8 is press-fitted into the glass groove 312a of the first mullion member 31, and the first mullion member 31, the drainage structure 8, the water blocking sheet 72, and the skirt portion 22 are combined with the screw 73. By tightening, the drainage structure 8 can be firmly attached to the glass groove 312a of the first mullion member 31. Further, between the through hole formed by the screw 73 in the first water-swellable water stop material 83 and the screw 73, there is no gap between the through hole of the first water-swellable water stop material 83 and the screw 73. Since it is penetrated, watertightness can be ensured.

Next, the action of the drainage structure 8 housed in the glass groove 312a to improve the watertightness with respect to the water that has entered the glass groove 312a of the first mullion member 31 will be described.
In the present embodiment, as shown in FIG. 2, the glass grooves 232a, 312a, and 322a (see FIG. 3) of the vertical frames 23, 24 and the mullion 25 are provided along the vertical direction of the glass grooves 232a, 312a, and 322a. Therefore, a plurality of drainage structures 8 are arranged. Therefore, even if water infiltrates in the glass grooves 232a, 312a, and 322a of the vertical frames 23, 24 and the mullion 25, the water reaches the drainage structure 8 from above to below the glass grooves 232a, 312a, and 322a. The amount of is reduced.

In the present embodiment, regarding the action of the drainage structure 8, the drainage structure 8 is arranged at a position lateral to the position where the xylem portion 22 is attached in the glass groove 312a of the first mullion member 31 of the mullion 25. The case where water such as rainwater reaches will be described.

Water such as rainwater that has entered the glass groove 312a of the first mullion member 31 is, for example, drainage that is arranged at a position lateral to the position where the xylem portion 22 is attached in the glass groove 312a of the first mullion member 31. It is received by the structure 8.

In the drainage structure 8, as shown in FIG. 9, a second water-swelling water blocking material 84 is provided on the upper surface of the drainage block 81. As a result, the water that has reached the second water-swelling water-stopping material 84 provided on the upper surface of the drainage block 81 is absorbed by the absorption layer of the second water-swelling water-stopping material 84 on the upper surface of the drainage block 81 and gels. It changes into a shape and expands. The second water-swellable water blocking material 84 holds the water that has changed into a gel on the upper surface of the drainage block 81 and expanded, on the upper surface of the drainage block 81. As a result, the water that has changed into a gel and expanded covers the upper surface of the drainage block 81.

In a state where water is expanded and held by the second water-swelling water-stopping material 84 on the upper surface of the drainage block 81, water reaches the drainage structure 8 and is held by the second water-swelling water-stopping material 84. When the permissible amount of water that can be produced is exceeded, the water that cannot be retained by the second water-swelling water blocking material 84 is in close contact with the glass groove 312a of the first cubic member 31 and the drainage structure 8. 1 It is difficult for water to flow between the glass groove 312a of the cubic member 31 and the drainage structure 8, and it flows to the glass groove 222a side of the widthwood portion 22 where the water flow path is secured. The water flowing through the glass groove 222a of the xylem portion 22 is discharged to the outside through a drain valve (not shown) provided in the middle of the glass groove 222a of the xylem portion 22.

Further, as shown in FIG. 6, a foaming material 82 is provided on the outer peripheral surface of the drainage block 81, and a first water-swellable water blocking material 83 is provided on the outer peripheral surface of the foaming material 82. ..

The foaming material 82 has both flexibility and a closed cell structure, is not permeable to water, has flexibility, and is pressed following the shape of the glass groove 312a of the first mullion member 31. .. Therefore, it is difficult to generate a gap such as a pinhole extending in the vertical direction between the glass groove 312a of the first mullion member 31 and the foaming material 82. As a result, it is possible to reduce the infiltration of water between the glass groove 312a of the first mullion member 31 and the foaming material 82.

Further, a first water-swelling water blocking material 83 is provided on the outer peripheral surface of the foam material 82. Therefore, the water that has reached the first water-swellable water blocking material 83 changes into a gel and expands. As a result, it is more difficult to form a gap such as a pinhole extending in the vertical direction between the glass groove 312a of the first mullion member 31 and the foaming material 82. As a result, it is possible to reduce the infiltration of water between the glass groove 312a of the first mullion member 31 and the foaming material 82.

The first water-swelling water-stopping material 83 and the second water-swelling water-stopping material 84 dry with the passage of time and return to their original states when the infiltration of water disappears after the infiltration of water. Specifically, the water absorbed by the absorption layer of the first water-swelling water-stopping material 83 and the second water-swelling water-stopping material 84 is absorbed by the absorption layer to form a gel, and then water infiltrates. When there is no more, it gradually evaporates. Then, in the first water-swelling water-stopping material 83 and the second water-swelling water-stopping material 84, the water absorbed in the absorption layer dries after evaporation, and after drying, solidifies into a paste-like state and is in the original state. Return to. The absorption layers of the first water-swellable water-stopping material 83 and the second water-swelling water-stopping material 84, which have returned to their original states, absorb the water that has subsequently infiltrated again and change into a gel again as described above. Can be inflated. As a result, the absorption layers of the first water-swelling water-stopping material 83 and the second water-swelling water-stopping material 84 can maintain the water-stopping function by repeating absorption and drying of water.

As described above, according to the present embodiment, the following effects are achieved.
The mullion 25 of the present embodiment includes a first mullion member 31 having a glass groove 312a, a second mullion member 32 having a glass groove 322a, and a back surface and a second surface of the glass groove 312a in the first mullion member 31. A fitting portion 300 that fits and connects the first mullion member 31 and the second mullion member 32 with the back surfaces of the glass grooves 322a of the mullion member 32 facing each other, and the back surface of the glass groove 312a and the glass groove. A mullion 25 including a first mullion member 31 and a water blocking member 10 formed by continuously extending in the longitudinal direction of the second mullion member 32, which is arranged between the back surface of the 322a. The fitting portion 300 is arranged on the outdoor side of the glass groove 312a and the glass groove 322a. Therefore, the water blocking member 10 makes the back surface of the glass groove 312a in the first mullion member 31 and the back surface of the glass groove 322a in the second mullion member 32 facing each other as a boundary in the prospective direction. The air pressure in the internal space can be divided into the air pressure on the indoor side and the air pressure on the outdoor side. As a result, it is possible to prevent water from being drawn into the mullion 25 from the fitting portion 300 arranged on the outdoor side of the glass groove 312a and the glass groove 322a. Therefore, the watertightness of the mullion 25 can be improved. For example, when the seal member 301 is arranged in the fitting portion 300, even if the seal member 301 arranged in the fitting portion 300 is damaged, the water blocking member 10 causes the sealing member 301 to move from the fitting portion 300. It is possible to prevent water from being drawn into the standing 25.

Further, in the present embodiment, the first mullion member 31 has a first mullion side screw hole 312h formed in a portion of the first mullion member 31 where the glass groove 312a is formed, and is the second mullion. The vertical member 32 has a second mullion-side screw hole 322g formed in the portion of the second mullion member 32 where the glass groove 322a is formed so as to face the first mullion-side screw hole 312h. A screw 71 for fastening the first mullion member 31 and the second mullion member 32 via the water blocking member 10 in a state of being inserted into the mullion side screw hole 312h and the second mullion side screw hole 322g. Further prepare.
Therefore, the water blocking member 10 can be reliably sandwiched between the first mullion member 31 and the second mullion member 32 by the screw 71. As a result, the water blocking member 10 can be reliably arranged between the back surface of the glass groove 312a and the back surface of the glass groove 322a, so that the watertightness of the mullion 25 can be improved.
Further, in a configuration in which the first mullion member 31 and the second mullion member 32 are fastened with the screw 71 inserted into the first mullion side screw hole 312h and the second mullion side screw hole 322g, a glass groove is formed. Even if water enters the 312a or the glass groove 322a, since the water blocking member 10 is sandwiched and screwed, the mullion 25 can be seen from the first mullion side screw hole 312h or the second mullion side screw hole 322g. It is possible to prevent water from being drawn into the inside.

Further, in the present embodiment, the space between the back surface of the glass groove 312a in the first mullion member 31 and the back surface of the glass groove 322a in the second mullion member 32 is a storage space in which the water blocking member 10 is housed. A compartment 100 is provided. As a result, by arranging the water blocking member 10 in the section 100, the water blocking member is located between the back surface of the glass groove 312a in the first mullion member 31 and the back surface of the glass groove 322a in the second mullion member 32. 10 can be easily and stably arranged. Therefore, the workability when attaching the water blocking member 10 can be improved. In addition, the water blocking member 10 can be stably held in the compartment 100. In particular, when the water blocking member 10 is composed of an elastic member, the water blocking member 10 is arranged inside the compartment 100 in a crushed state so as to be held by the compartment 100 by an elastic returning force. As a result, the water stop member 10 can be held more stably in the state where the water stop member 10 is compressed in the compartment 100.
