Description

  The present invention is for discharging accumulated water generated in an interior space of a metal underframe facing outdoors such as a top light for lighting provided on a sloped roof or a flat roof of a building such as a house, and a head wall provided on a waist wall. It relates to the water drainage parts.

  Conventionally, for the case where the sealing part of the glass surface of the lighting toplight provided on the roof or roof of a building such as a house deteriorates and rainwater blows in from there and penetrates into the lighting toplight. A drainage hole is formed at the bottom of the daylighting toplight, and rainwater blown into the daylighting toplight is drained from the drainage hole.

  There is no problem when the owner of the building replaces the seal part at an appropriate time before the rainwater penetrates the seal part of the glass surface of the toplight for lighting and deteriorates. When the maintenance time is delayed and the seal part deteriorates severely, a large amount of rainwater enters the toplight for lighting during heavy rains such as typhoons. The amount of water may increase, overflowing the rainwater catcher and leading to rain leaks indoors.

  However, if a large drainage hole is drilled, the conventional structure in which a draining plate is installed on the surface has the opposite effect because rainwater flows backward from the drainage hole during a typhoon and leaks indoors. At present, there is no drain hole with a large opening area.

  Therefore, the seal part of the glass surface of the daylighting top light is deteriorated for a long time, and even if a large amount of rainwater enters, the area of the drainage hole that can be discharged can be secured, and the rainwater blown in does not flow back during a typhoon A structure is required.

  In addition, rainwater from the joints of the joints of the headboards and the handrails attached to the upper part may also accumulate in the inner space of the lower frame of the headboards provided at the upper end of the waist wall of the veranda etc. A structure that can be made is required.

  For example, Japanese Patent Application Laid-Open No. 11-291755 shows an example in which a check valve is used in a water drain structure under a sliding glass window in a vehicle wind sash.

JP-A-11-291755

  However, the above-described conventional example has a problem that it cannot be applied to a lighting toplight or a drainage structure of rainwater that has entered the headboard.

  The present invention solves the above-mentioned problems, and an object of the present invention is, for example, water that can be discharged even when a large amount of rainwater enters due to a long-term deterioration of the sealing portion of the glass surface of the daylighting toplight. The area of the hole can be secured, and in the case of a typhoon, the rainwater blown in does not flow back and can be installed later as maintenance work. It is what.

Configuration of drainage part of the lower frame according to the present invention for achieving the above object, have a contour shape corresponding to the shape of the water drain hole near the lower frame drainage hole at the bottom is provided, and water receiving port provided at a portion corresponding to the drainage hole of the lower frame, and the water receiving port communicated with the water discharge port, provided from the water receiving port on passage leading to the water outlet A non-return valve , the upper end side of the non-return valve is supported so as to be freely rotatable, and is maintained in a closed state when receiving wind pressure from the outside and the normal side. It changes to an open state by the water flow which goes to the said water discharge port from .

  According to the above configuration, drainage water generated in the interior space of the metal underframe facing the outdoors, such as the daylighting toplights provided on the sloped roofs and flat roofs of buildings such as houses and the rust walls, is discharged. I can do it.

  For example, when it is installed on the lower frame of the lighting top light, it is particularly effective as a water draining part to be attached later during maintenance work. The rainwater that has entered the inside of the daylighting top light from the section is discharged to the outside, and the check valve can prevent the rainwater from flowing back through the drainage hole during strong winds.

  Moreover, it can be constructed even at the time of new construction or at the time of renovation, and the aesthetics are not uncomfortable. As can be done in maintenance work, a glass drainage hole with a large opening area at the bottom of the lighting top light, that is, an area that can be discharged even if a large amount of rainwater enters, is constructed for a long time. Even if the seal on the surface is cut and rainwater enters, it does not leak into the room, can be discharged from the drain hole, and can be prevented from flowing back in the typhoon and entering the room in a rain leak state.

  Further, it is possible to flexibly cope with the shape of the opening of the drain hole in the lower frame of the daylighting top light and the storage and shape of the building components around the lower part of the daylighting toplight.

  An embodiment of the drainage part of the lower frame according to the present invention will be specifically described with reference to the drawings.

FIG. 3 is an explanatory perspective view showing the configuration of the first embodiment, and FIG. 3 is an AA cross-sectional explanatory view of FIG. 2 showing the configuration of the first embodiment of the draining part of the lower frame according to the present invention.

  In FIG. 1, reference numeral 1 denotes a lower portion of a lighting toplight provided on a sloped roof of a building such as a house formed of a glass surface, and 2 denotes a sash frame of the lighting toplight 1. A water receiving portion 2a is provided at the lower peripheral portion of the sash frame 2, and a drain hole 2b is formed at the lowermost portion of the peripheral portion of the water receiving portion 2a.

  Denoted at 3 is a drainage part comprising a hollow housing having an outer shape corresponding to the outermost shape at or near the lowermost part of the daylighting toplight 1 provided with a drainage hole 2b at the lowermost part. The drainage part 3 of the present embodiment is made of hard vinyl chloride having a thickness of about 2 mm, for example. Alternatively, it may be made of steel metal.

  As shown in FIGS. 2 and 3, the hollow housing of the water drainage component 3 is provided with a water receiving port 3a at a portion corresponding to the water draining hole 2b of the lighting toplight 1, and a water receiving port 3a is provided at the lower portion of the hollow housing. A water discharge port 3b communicated with the receiving port 3a is provided, and a vane plate 5 serving as a check valve is provided in the passage 4 from the water receiving port 3a to the water discharge port 3b.

  The hollow housing constituting the water drainage component 3 has an L-shaped cross section, and a water receiving port 3a is provided on the water drainage hole 2b side of the lighting top light 1 in the vertical portion 3c of the hollow housing. Yes. In the drain hole 2b of the present embodiment, for example, about 15 holes with a diameter of 8 mm are provided in a sash frame 2 with a plate thickness of 2 mm.

  Further, a water discharge port 3b is provided at the tip of the horizontal portion 3d of the hollow casing of the water draining part 3. The water discharge port 3b according to the present embodiment is, for example, a mesh formed with holes of 3 mm × 3 mm in length and width. Further, the bottom surface 3d1 of the horizontal portion 3d of the hollow casing of the water drainage part 3 is formed in a downward slope toward the water discharge port 3b at the tip. When the cut-off portion of the daylighting toplight 1 becomes larger, fine particles such as sand and exhaust gas enter from there, but the slope is downward to make the drainage smooth. However, this gradient is not necessary.

  The vane plate 5 serving as a check valve is pivotally supported around the support shaft 5a with respect to the hollow casing of the water drainage component 3, and the water discharge port 3b of the horizontal portion 3d of the water drainage component 3 is supported. A passage 4a having a predetermined length is provided from the blade plate 5 provided on the opposite end to the water discharge port 3b.

  As shown in FIG. 3, the slat 5 provided in the passage 4 has a clearance of about 2 mm between the tip of the slat 5 and the bottom 3d1 of the horizontal part 3d. When the wind pressure blown from the water discharge port 3b is formed, the vane plate 5 comes into contact with the contact member 9 provided on the bottom surface 3d1 of the horizontal portion 3d to contact the water receiving port 3a from the water discharge port 3b. By blocking the passage 4 leading to the water, it is possible to prevent a backflow of rainwater caused by blowing in by a typhoon or the like and to prevent water leakage into the room.

  When the slats 5 are pressed by the water flow flowing from the water receiving port 3a to the water outlet 3b, the slats 5 are rotated in the counterclockwise direction of FIG. 3 around the support shaft 5a. The passage 4 from the inlet 3a to the water outlet 3b is opened, and rainwater can be drained from the water inlet 3a to the water outlet 3b.

With the above configuration, it is effective as a water draining part 3 to be attached later at the time of maintenance work. Contact can Te, then the drain part 3 installed in the lower part of the lighting for the top light 1, to discharge the rain water entering from the seal cutting unit to the glass surface or the frame joint on the inside of the lighting for the top light 1 to the outside At the same time, the slat 5 serving as a check valve can prevent rainwater from flowing back from the drain hole 2b during strong winds.

  Moreover, it can be constructed at the time of new construction or at the time of refurbishment, and there is no sense of incongruity, and a drain hole 2b having a large opening area is constructed at the bottom of the lighting toplight 1 so that it can be carried out by maintenance work. Even if the glass surface seal is cut for a long time and rainwater enters, it will not leak into the room, it can be discharged from the drain hole 2b, and it can prevent backflow during a typhoon and a rain leak into the room. I can do it.

  Next, the structure of 2nd Embodiment at the time of applying the draining part of the lower frame which concerns on this invention to the lower frame of the lighting top light using FIGS. 4-7 is demonstrated. FIG. 4A is a cross-sectional explanatory view showing a state in which the second embodiment of the draining part of the lower frame according to the present invention is provided at the lowermost part of the daylighting top light, and FIG.
