Description

The present invention relates to a drainage structure of a fitting having a drainage port in a frame body.

For fittings installed in windows and doorways of buildings, a configuration in which a drainage port is provided at the bottom of a lower frame or a vertical frame of a frame that supports shoji is widely adopted. The drainage port is formed, for example, on the outdoor side finding surface of the lower frame, and can discharge rainwater, condensed water, etc. that have flowed into the inside of the frame to the outside.

By the way, in the case of a fitting having a drainage port, rainwater or the like that has flowed into the inside of the frame due to rainfall or the like is intensively discharged from the drainage port. Therefore, when there is a member below the drain port, the drainage from the drain port is concentrated and flows down to this member, and there is a concern that the member may be locally soiled or deteriorated. For example, in Patent Document 1, in order to prevent the drainage from the drainage port from being transmitted to the outer wall of the building and causing dirt to adhere to the outer wall, a drainage member is provided on the outer wall below the drainage port, and the drainage is transmitted through the outer wall. A configuration that prevents the water from flowing down is disclosed.

Japanese Patent No. 4794774

By the way, in a configuration in which a balcony, a terrace, or the like is installed on the outdoor side of the building, the drainage from the drainage port of the fittings flows down to the upper surface of the deck constituting the floor surface of the balcony or the terrace. Then, water flows down to the upper surface of the deck in a concentrated manner below the drainage port, so that a deep puddle remains in this part for a long time as compared with other parts, which may cause moss and dirt. In particular, when the deck material is made of wood, recycled wood, or the like, the wood and wood powder are discolored by the water accumulated in the portion below the drainage port, and the appearance quality is deteriorated. On the other hand, since the drainage member of Patent Document 1 has a structure in which drainage flows from the outer wall of the building to the outdoor side, when applied to a configuration in which a deck is provided below, the drainage member from the drainage member flows from the upper surface of the deck. It flows down as it is. That is, the configuration of Patent Document 1 cannot prevent problems such as local moss, stains, and discoloration on the deck below the frame.

The present invention has been made in consideration of the above-mentioned problems of the prior art, and can prevent the deck installed below the fitting from being soiled or discolored due to the drainage from the drainage port of the fitting. The purpose is to provide a drainage structure.

The drainage structure of the fitting according to the present invention includes a frame body fixed to the opening of the skeleton of the building above the deck installed on the outdoor side of the outer wall of the building, and the lower frame or the vertical frame of the frame body. It is a drainage structure of a fitting provided with a drainage port at the lower part of the above, and the drainage port is provided at a portion of the lower frame or a portion of the lower part of the vertical frame protruding to the outside of the outer wall, and the deck is provided. It is characterized in that a drainage component which is arranged at a position overlapping below the drainage port in a plan view and can discharge water flowing down from the drainage port to other than the upper surface of the deck is provided on the upper surface of the deck. ..

According to such a configuration, the drainage from the drainage port provided at the lower part of the lower frame or the vertical frame is discharged to other than the upper surface of the deck through the drainage component. Therefore, it is possible to prevent the drainage from the drain port from flowing down to a part of the upper surface of the deck in a concentrated manner and causing local moss, dirt, discoloration, etc. on the upper surface of the deck.

In the drainage structure of the fitting according to the present invention, the deck is arranged so that one end surface on the outer wall side is provided with a gap between the deck and the outer wall, and the drainage component draws water that has flowed down from the drainage port. It may be configured so that it can be discharged into a gap. Then, the drainage from the drainage port can be discharged to the gap between the deck and the outer wall, which is inconspicuous in the appearance of the building or deck on which the fitting is installed.

In the drainage structure of the fitting according to the present invention, the drainage component has a drainage surface extending in a direction from the deck side to the outer wall side, and one end of the drainage surface on the outer wall side is said in a plan view. It is arranged at a position where it overlaps with the one end surface of the deck or at a position where it overlaps above the gap, and the other end of the drainage surface opposite to the one end is separated from the outer wall from a position where it overlaps below the drainage port. It may be configured so as to be arranged at the above-mentioned position. Then, the drainage from the drainage port can be discharged more smoothly into the gap between the deck and the outer wall through the drainage component.

In the drainage structure of the fitting according to the present invention, the drainage surface may have a left-right width dimension larger than the left-right width dimension of the drainage port when the frame body is viewed from the outdoor side. Then, the drainage from the drainage port can be reliably received and stopped by the drainage surface and discharged to the outside of the deck.

In the drainage structure of the fitting according to the present invention, the drainage surface may be formed by an inclined surface inclined downward from the other end portion toward the one end portion. Then, the drainage from the drainage port can be smoothly discharged to the outside of the deck by flowing on the drainage surface.

In the drainage structure of the fitting according to the present invention, the drainage component may have a water blocking wall that stands up around the drainage surface at an end portion other than the one end portion of the drainage surface. Then, it is possible to prevent the water flowing on the drainage surface from flowing out from the end portion other than the one end portion which is the discharge port.

According to the present invention, it is possible to prevent the deck installed below the fitting from being soiled or discolored due to the drainage from the drainage port of the fitting.

Hereinafter, a suitable embodiment of the drainage structure of the fitting according to the present invention will be described and described in detail with reference to the accompanying drawings.

FIG. 1 is a front view of the fitting 12 and the deck 14 to which the drainage structure 10 of the fitting according to the embodiment of the present invention is applied, as viewed from the outdoor side. FIG. 2 is an enlarged vertical cross-sectional view of the main parts of the fitting 12 and the deck 14 shown in FIG. In the present embodiment, the drainage structure 10 of the fitting including the structure in which the deck 14 forming the floor of the terrace is installed below the outdoor side of the fitting 12 composed of the sliding window (hereinafter, also simply referred to as “drainage structure 10”). Is illustrated. The fitting 12 may be a window type other than the sliding window, for example, another sliding window including a single sliding window, a rotating window such as a casement window, a door, or the like. The deck 14 may constitute an outdoor structure other than a terrace, for example, a floor surface of a balcony, or a structure in which a concrete surface or the like is used as it is as a floor surface without having a deck material 42 described later. May be good.

As shown in FIGS. 1 and 2, the fitting 12 is a window installed in the opening 16b of the skeleton 16a of the building 16 and serving as an entrance / exit to the deck 14 installed on the outdoor side of the outer wall 16c of the building 16. The fitting 12 includes a frame body 18 fixed to the opening 16b, and a pair of left and right shoji screens 20 and 21 slidably supported by the frame body 18. The shoji screens 20 and 21 have a structure in which a face material such as a glass plate is held by, for example, a resin or metal frame.

The frame body 18 has a rectangular opening formed by framing the upper frame 18a, the lower frame 18b, and the left and right vertical frames 18c and 18d in four directions. The frame body 18 is an extruded shape material of a resin such as vinyl chloride resin (PVC). The frame body 18 may be an extruded profile of a metal such as aluminum, or may have a composite structure in which a resin profile is attached to the metal profile. The frame body 18 is fixed to the skeleton 16a by using a fixture 22 such as a nail or a screw.

In the present application, the prospective direction means the indoor / outdoor direction of the fitting 12, that is, the direction from the indoor side to the outdoor side or the opposite direction (the direction indicated by the arrow Y in the figure), and the prospective surface is along the prospective direction. It refers to the extending surface. The finding direction is a direction orthogonal to the expected direction, and in the case of a vertically long vertical frame 18c or the like, it means a left-right direction (direction indicated by an arrow X in the figure) orthogonal to the longitudinal direction, and is in the left-right direction. In the case of a long upper frame 18a or the like, it means a vertical direction (direction indicated by an arrow Z in the drawing) orthogonal to the longitudinal direction thereof. The finding surface is a surface along the finding direction. The inside (inner circumference) of the frame-shaped member means, for example, the inside of the frame of the frame body 18, and the outside (outer circumference) of the frame-shaped member means, for example, the outside of the frame fixed to the skeleton 16a of the frame body 18.

As shown in FIG. 2, the lower frame 18b is formed with drainage ports 26a and 26b penetrating through the outdoor side finding surface 24. In the case of the present embodiment, the lower frame 18b is divided into upper and lower two stages by a partition wall 28 extending in a substantially prospective direction. Therefore, the lower frame 18b is provided with a pair of upper and lower drainage ports 26a and 26b so as to correspond to the upper space and the lower space of the partition wall 28, respectively. A pair of drainage ports 26a and 26b are provided on the left and right in the longitudinal direction of the lower frame 18b (see FIG. 1). For example, the drainage port 26a may be omitted and only the drainage port 26b may be provided. Rails 30a and 30b on which the shoji screens 20 and 21 travel are projected on the upper surface (inner surface) of the partition wall 28. The upper drainage port 26a discharges rainwater or the like flowing on the upper surface of the partition wall 28 to the outside through holes or openings formed in the finding pieces or the like between the rails 30a and 30b and the rails 30a and 30b. The lower drainage port 26b flows down from the hole formed in the partition wall 28 to the plurality of hollow portions 31 on the lower side (outside), and passes through the hole or opening formed in the partition wall between the hollow portions 31. Drain the rainwater, etc. to the outside.

A drain valve 32 is attached to each of the drain ports 26a and 26b. The drain valve 32 is fitted and mounted on the drain ports 26a and 26b from the outdoor side. The drain valve 32 is normally closed by a valve body, and can be opened by the water pressure of water from the inside of the lower frame 18b toward the outdoor side. The drain valve 32 may have a simple cap structure or the like that does not have a valve body and is always open. The drain valve 32 may be omitted.

As shown in FIG. 2, the outdoor side portion of the frame body 18 projects to the outdoor side of the outer wall 16c. That is, the lower frame 18b has an overhanging portion 34 overhanging to the outside of the outer wall 16c. The drainage ports 26a and 26b are provided on the outdoor side finding surface 24 located at the overhanging portion 34. The overhanging portion 34 is firmly supported on the outdoor side wall surface of the skeleton 16a by using a substantially L-shaped bracket 36.

The deck 14 has a configuration in which the deck material 42 is supported by a plurality of joists 40 fixed to the upper ends of the plurality of bundle columns 38. Each bundle pillar 38 stands on the ground 44, and a joist 40 extends between the upper ends of the bundle pillars 38, 38 on both sides in the X direction. In the present embodiment, the berm 16e is installed on the outdoor side edge of the foundation 16d of the building 16 formed of concrete or the like. In the configuration example shown in FIG. 2, the berm 16e is also shown as a part of the ground 44. The deck material 42 is a rectangular tubular member provided with a hollow portion to ensure strength, and extends in the indoor / outdoor direction (Y direction). A plurality of deck members 42 are arranged side by side along the longitudinal direction (X direction) of the lower frame 18b at the upper part of the joists 40, and the floor surface (upper surface 14a) of the deck 14 is formed by each of these deck materials 42. .. The deck material 42 is formed of a recycled wood board obtained by solidifying wood powder with resin. The deck material 42 may be made of a natural wood board, a resin board, or the like.

As shown in FIG. 2, the deck 14 is located at a position where one end surface 14b on the outer wall 16c side is recessed below the overhanging portion 34 of the lower frame 18b. That is, the deck 14 is arranged at a position overlapping below the drainage ports 26a and 26b in a plan view, and a certain amount of space is formed between the deck 14 and the lower surface of the lower frame 18b. One end surface 14b of the deck 14 is arranged with a gap C of, for example, about 8 mm from the outer wall 16c of the building 16. This gap C is an escape portion for preventing the deck material 42 from interfering with the outer wall 16c when, for example, a person walks on the deck 14 and the deck material 42 or the joist 40 bends.

In such a configuration in which one end surface 14b of the deck 14 is recessed below the fitting 12, the upper surface 14a of the deck 14 is arranged at a position overlapping below the drainage ports 26a and 26b (see FIG. 2). Therefore, when the rainwater or the like that has entered the inside of the frame body 18 is drained from the drain ports 26a and 26b, it flows down intensively to a fixed position on the upper surface 14a of the deck 14. Then, as described above, local moss, stains, and discoloration may occur on the deck material 42 below the drain ports 26a and 26b. Therefore, in the drainage structure 10, the drainage component 50 is attached to the upper surface 14a of the deck 14 to prevent local stains and discoloration on the deck material 42.

FIG. 3 is an enlarged vertical sectional view of the drainage component 50 and its peripheral portion. FIG. 4 is a plan view schematically showing the arrangement relationship between the drainage ports 26a and 26b (drainage valve 32), the outer wall 16c, the deck 14, and the drainage component 50. FIG. 5 is a perspective view schematically showing the configuration of the drainage component 50.

The drainage component 50 is arranged on the upper surface 14a of the deck 14, and drains rainwater or the like that has flowed down from the drainage ports 26a and 26b to the outside of the deck 14. As shown in FIGS. 3 to 5, the drainage component 50 is a gutter-shaped component formed of a non-water-absorbent or low-absorbent resin or the like, and has a drainage surface 52 and water blocking walls 54a, 54b, 54c. It has a dustpan shape.

The drainage surface 52 is formed on the upper surface of the drainage component 50, receives the water that has flowed down from the drainage ports 26a and 26b, and forms the bottom surface of the flow path that flows to the outside of the deck 14. The drainage surface 52 extends in the direction (Y direction) from the deck 14 side toward the outer wall 16c side. The drainage surface 52 is arranged at a position where one end 52a on the outer wall 16c side overlaps above the gap C, and the other end 52b on the opposite side overlaps below the drainage ports 26a and 26b in the Y direction from the outer wall 16c. It is placed at a distance. The drainage surface 52 has a left-right width dimension (X-direction dimension) equal to or greater than the left-right width dimension (X-direction dimension) of the drainage ports 26a and 26b (or the drainage port of the drain valve 32) in the front view shown in FIG. See also FIG. 4). In the case of this embodiment, the left-right width dimension of the drainage surface 52 is larger than that of the drainage ports 26a and 26b. The water that has flowed through the drainage surface 52 falls from one end portion 52a that serves as a drainage port into the gap C. In the case of the present embodiment, the drainage surface 52 is composed of an inclined surface gradually inclined downward from the other end 52b on the upstream side toward the one end 52a on the downstream side, so that a smoother flow of water is ensured. Will be done. The one end portion 52a may be set at a position overlapping the one end surface 14b of the deck 14, that is, at a position flush with the one end surface 14b.

The water stop walls 54a to 54c stand up so as to surround the drainage surface 52 from three ends excluding one end 52a which is a discharge port of the drainage surface 52. The water stop walls 54a to 54c are embankments that prevent the water flowing through the drainage surface 52 from flowing out from the ends other than the one end 52a. In the case of the present embodiment, since the drainage surface 52 is an inclined surface that descends from the other end 52b toward the one end 52a, the water always goes toward the one end 52a due to gravity. Therefore, the water blocking wall 54b on the other end 52b side may be omitted. Further, for example, when the drainage surface 52 is not a flat surface but a curved surface recessed toward the center in the X direction, all the water blocking walls 54a to 54c may be omitted. On the contrary, when the water blocking walls 54a to 54c are provided, the drainage surface 52 may be formed of a horizontal surface instead of an inclined surface.

As shown in FIGS. 3 and 4, the drainage component 50 is placed on the upper surface 14a of the deck 14 at a position where one end 52a protrudes from one end surface 14b of the deck 14 toward the gap C side in the indoor / outdoor direction (Y direction). It is fixed. The lower surface of the drainage component 50 is fixed to the upper surface 14a of the deck 14 with an adhesive, double-sided tape, screws, or the like. The drainage component 50 is arranged at a position where the drainage surface 52 overlaps below the drainage ports 26a and 26b (drainage valve 32) in the longitudinal direction (X direction) of the lower frame 18b (see also FIG. 1).

Next, the drainage operation and operation in the drainage structure 10 of the fitting according to the present embodiment will be described. The arrow indicated by the alternate long and short dash line in FIG. 3 exemplifies the distribution locus of water W discharged from the drainage ports 26a and 26b.

As shown in FIG. 3, when the fitting 12 receives precipitation or the like and water W such as rainwater flows into the frame 18, the water W flows in the lower frame 18b from the indoor side to the outdoor side. The water is discharged from the drain ports 26a and 26b to the outside of the lower frame 18b via the drain valve 32. Then, the water W flows down onto the drainage surface 52 of the drainage component 50 arranged below the drainage ports 26a and 26b, and flows on the drainage surface 52 from the other end 52b side toward the one end 52a side. Then, the water W flows down from one end 52a of the drainage surface 52 into the gap C, and then flows down to the ground 44 (dog running 16e) through the drainer 16f protruding from the lower part of the outer wall 16c.

Therefore, the drainage structure 10 can discharge the drainage from the drainage ports 26a and 26b to the outside of the gap C, that is, the outer peripheral edge portion of the upper surface 14a of the deck 14 through the drainage component 50. Therefore, it is possible to prevent the drainage from the drainage ports 26a and 26b from flowing down to a part of the upper surface 14a of the deck material 42, causing the deck material 42 to locally generate moss, stains, discoloration, and the like. Further, since the drainage component 50 drains into the gap C on the indoor side of the deck 14 whose upper portion is hidden by the frame body 18, the drainage from the drainage component 50 is not conspicuous. In this way, the drainage structure 10 only needs to fix the drainage component 50 to the upper surface 14a of the deck 14, and the drainage component 50 can be easily retrofitted even after the fitting 12 and the deck 14 are constructed. Therefore, the drainage structure 10 can be applied regardless of the window type of the fitting 12, the type and material of the deck 14, and is highly versatile.

By the way, in the case of the present embodiment, the fitting 12 is a resin sash in which the frame body 18 is made of resin. Therefore, as shown in FIG. 1, each of the frames 18a to 18d of the frame body 18 is joined with the cut surfaces having 45 degree ends thereof, and the lower frame 18b forms a drainage port on the lower surface thereof. It's difficult. Therefore, in the fitting 12, the drainage ports 26a and 26b are formed on the outdoor side finding surface 24 of the lower frame 18b. That is, when the fitting 12 is a resin sash, the drainage from the drain ports 26a and 26b flows down to a position exposed to the outdoor side rather than a position where the drainage from the drain ports 26a and 26b overlaps below the lower frame 18b on the upper surface 14a of the deck 14, and stains and discoloration occur. There is a concern that it may occur in a conspicuous place on the deck 14. In this respect, the drainage structure 10 can solve the problem of such a resin sash only by providing the drainage component 50.

FIG. 6 is a side view of the drainage component 60 according to the modified example. As shown in FIG. 6, the drainage component 60 is provided with a positioning piece 62 on the lower surface side of one end portion 52a as compared with the drainage component 50 shown in FIG. The positioning piece 62 extends in the width direction (X direction) of the drainage surface 52, and projects downward from one end portion 52a of the lower surface of the drainage component 60. The drainage component 60 can be accurately positioned with respect to the deck 14 at a desired indoor / outdoor direction position by arranging the outdoor side surface 62a of the positioning piece 62 in contact with one end surface 14b of the deck 14.

By the way, depending on the specifications of the outer wall 16c of the building 16 and the structure of the deck 14, for example, the gap C is very narrow, and when the positioning piece 62 is to be positioned on one end surface 14b of the deck 14 via the gap C, the drainage component 60 It is also assumed that one end portion 52a of the water is in contact with the outer wall 16c. Therefore, in order to deal with such a problem, the drainage component 60 may be formed of, for example, a material that can easily cut the one end 52a side at a predetermined distance in a direction parallel to the one end 52a. Alternatively, the drainage component 60 is formed by forming cutting lines (breaking grooves) 64 extending in the X direction shown by the two-dot chain line in FIG. 6 at predetermined intervals in the Y direction, and cutting or cutting with reference to the cutting line 64. It may be cut off and its length adjusted. The drainage component 50 shown in FIG. 5 may also have a problem that one end portion 52a of the drainage component 50 abuts on one end surface 14b of the deck 14. Therefore, the material that is easy to cut and the cutting line 64 may of course be applied to the drainage component 50.

It should be noted that the present invention is not limited to the above-described embodiment, and of course, it can be freely changed without departing from the gist of the present invention.

In the above, the drainage ports 26a and 26b are provided on the outdoor side finding surface 24 of the lower frame 18b, but the drainage ports 26a and 26b are provided on the lower surface (outside prospective surface) of the lower frame 18b, for example. May be good. Further, the drainage ports 26a and 26b may be formed of, for example, an opening having a shape in which the outdoor side finding surface 24 is cut out downward from the upper end surface, instead of the hole portion. When the frame body 18 has a vertical winning structure in which a part of the left and right vertical frames 18c and 18d is cut out and the left and right ends of the lower frame 18b are connected by an inlay type, respectively, the outer walls of the vertical frames 18c and 18d are connected. A cap component that hides the cap component may be attached to the lower end edge of the portion protruding to the outdoor side of 16c, and a drain port may be formed on the lower surface of the cap component. In this case, the drainage parts 50 and 60 may be provided so that the drainage flowing down from the drainage port provided at the lower part of the vertical frames 18c and 18d can be discharged to the outside of the upper surface 14a of the deck 14.

In the above, the drainage parts 50 and 60 exemplify the configuration in which the drainage from the drainage ports 26a and 26b is discharged from the upper surface 14a of the deck 14 to the gap C. As long as it can be discharged to the outside, for example, it may be configured to discharge to the outside of the left and right edges of the upper surface 14a of the deck 14 in the front view shown in FIG.
