Description

  The present invention relates to an eaves structure of a building.

  Conventionally, eaves have been provided at the eaves, and measures have been taken to prevent the rain on the eaves from bouncing back and entering the eaves. For example, in the eaves tip structure disclosed in Patent Document 1, a draining plate is provided on the extension of the roof plate, and a swash plate is provided as an eaves tip draining on the front end portion thereof. The draining plate is fixed to the front end portion of the eaves with a screw or the like and is bent downward, and the front end portion thereof is provided close to the eaves bowl. As a result, rainwater is guided to the draining board and flows through the eaves so that the rainwater does not jump up, and the nose can be prevented from getting dirty and corroded without getting wet.

JP 2009-30300 A

  However, in the case of the above prior art, since the draining plate is provided with a plurality of through holes for screwing screws or the like, rain water bounced off by the eaves can enter the through holes and wrap around the outside of the eaves There was sex. Moreover, since the draining board is not provided in the location where the fence hanging bracket is arranged, there is a possibility that the rain water falling on the eave fence jumps up and goes outside the eave fence.

  In recent years, local rainfall called guerrilla heavy rain has frequently occurred, and a large amount of rainwater can flow through the eaves in a short time. In such a case, it is conceivable that rainwater bounces off the eaves and the rainwater overflows, and the possibility of rainwater entering the back of the eaves from the gap between eaves is increased. When rainwater infiltrates, rainwater drops inside the fence and accumulates at the top of the eaves ceiling, which may cause stains and discoloration on the eaves ceiling.

  The present invention has been made in view of the above problems, and its purpose is to provide a structure that reliably collects and drains rainwater to the eaves and prevents rainwater from flowing to the eaves ceiling. Thus, even if rainwater enters the back side of the eaves wall, it is intended to provide an eaves tip structure that can guide the rainwater to the outdoor side and prevent the eaves ceiling from getting wet.

  The solution of the present invention for achieving the above object is based on an eaves structure provided with eaves along the nose cover part of the eaves and having a decorative member disposed on the outdoor side of the eaves. The eaves holder and the decorative member support are attached to the portion with a space therebetween, and the eaves bowl is supported by the receiver with a water gradient. A draining material is hung from the upper end of the eaves toward the eaves, and a recess from the back side of the draining material to the nasal concealment is covered by the inner draining, and an auxiliary draining is added to the inner draining. The auxiliary drainer is covered on the indoor side edge of the eaves and is hung down toward the eaves and covers the joint on the indoor side of the eaves and the receiving device. The decorative member is provided with a water receiving groove in the lower part on the indoor side, and the lower end edge of the internal drainer is configured to extend toward the water receiving groove of the decorative member.

  By such specific matters, rainwater can be collected in the eaves and drained from the eaves can be collected and drained to the eaves without entering the backside of the eaves by internal drainage and auxiliary drainage. . Even if rainwater goes around to the back of the eaves, the rainwater can be guided to the drainage groove on the exterior of the eaves through the drainage of the eaves. Wetting is prevented.

  In the eaves-end structure, the joint portion on the outdoor side of the eaves basket and the receiving member is covered with a cover member, and the cover member is preferably joined to the decorative member at the edge portion on the outdoor side and covered with a sealing material. .

  As a result, water is doubled by the internal drainage and auxiliary drainage on the indoor side of the eaves, and water is doubled by the cover member and the sealing material on the outdoor side of the eaves. , Rainwater can be made difficult to go around the back of the eaves.

  The inner drainer includes an attachment plate part joined to the nose cover part, an upper cover part extending from the upper part of the attachment plate part toward the distal end of the drainer material and covering between the drainage material and the nose cover part, and an attachment plate A lower cover portion extending from the lower portion of the decorative member along the support of the decorative member and covering the outer surface of the eaves ridge, and a lower draining plate portion extending from the tip of the lower cover portion to the inside of the water receiving groove of the decorative member are integrally provided. A configuration is preferred.

  As a result, the rainwater bounced off from the eaves usually hits the upper cover part of the drainage and flows to the eaves. When there is a lot of rainfall, even if rainwater enters the back of the eaves, the rainwater can flow down through the internal drainer and be guided to the lower drainer. Since rainwater led to the lower draining plate portion flows into the water receiving groove of the decorative member and is drained, it is possible to prevent the eaves ceiling from getting wet.

  In the present invention, in addition to the draining material at the eaves end, an internal draining and an auxiliary draining are provided, and the wraparound of rainwater to the indoor side of the eaves is reduced. Even if rainwater enters the back side of the eaves, the rainwater can be guided and drained to the outdoor side of the eaves by draining the inside of the eaves, so that a situation where the eaves ceiling gets wet can be avoided.

The water receiving groove 33 is provided on the back side of the lower flange portion 31 along the longitudinal direction. As shown in FIG. 2 and FIG. 3, the water receiving groove 33 is formed in a concave groove shape with a rising edge provided at the indoor side edge of the lower flange portion 31. The lower draining plate portion 64 of the inner drainer 6 extends toward the water receiving groove 33 of the decorative member 3.

  An auxiliary drainer 7 is attached to the inner drainer 6. The auxiliary drainer 7 includes a support plate portion 71 disposed so as to overlap the mounting plate portion 62 of the inner drainer 6, and a drainer plate portion 72 extending from above the support plate portion 71 toward the eaves bowl 4. It is prepared as one. The draining plate portion 72 has a portion formed with a water drooping gradient obliquely downward and a portion extending vertically downward from the tip thereof. The auxiliary drainer 7 is provided so as to cover the indoor side edge of the eaves basket 4 by the support plate part 71 and the drainer board part 72 and cover the joint portion on the indoor side of the eaves basket 4 and the receiving device 40 from above. It has been.

  The joint portion on the outdoor side of the eaves 4 and the receiving tool 40 is covered with a cover member 8. The edge part on the outdoor side of the eaves basket 4 is overlapped on the edge part on the outdoor side of the receiving device 40, and is pressed by a band 401 provided in the receiving device 40. The cover member 8 is disposed so as to cover the joint portion on the outdoor side of the eaves rod 4 and the receiving tool 40. Furthermore, the edge portion on the outdoor side of the cover member 8 is joined to the back surface of the decorative member 3 and covered with a sealing material 81.

  As shown in FIG. 5, the eaves-end structure is constructed by sequentially arranging a roof base 21 and a roof material 22 on the roof frame 23 of the eaves 2. The inner drainer 6, the auxiliary drainer 7, and the support tool 30 are attached to the nose cover portion 202 of the roof frame 23 in order. As shown in FIG. 4, the attachment 40 of the eaves basket 4 is attached according to the water gradient of the eaves basket 4 by adjusting the attachment level by the long hole 231. The internal drainer 6 and the auxiliary drainer 7 are integrated with the roof frame 23 in advance and are carried into the construction site, so that the construction can be performed in a short period of time with high accuracy.

  Next, the decorative member 3 is attached to the support 30 using the bolts and nuts 53 via the joining members 32. The eaves ridge 4 is fitted into the receptacle 40 from above, and the eave ridge 4 is fixed. The water gradient of the eaves 4 can be adjusted by the fixing position of the receptacle 40 as described above.

  Next, the cover member 8 is fitted into the joint portion on the outdoor side of the eaves basket 4 and the receiving tool 40. The edge portion on the outdoor side of the cover member 8 is fixed to the joining member 32 and is covered with the sealing material 81 from above. Thereby, the eaves structure which concerns on embodiment is constructed.

  In the eaves tip structure having the above-described configuration, rainwater that has flowed through the roofing material 22 is collected in the eaves wall 4 through the draining material 27 during the rain. The rainwater of the eaves 4 flows down to the bottom. When there is a lot of rainfall or strong wind and rain, the rain water falling on the eaves 4 may hit the bottom of the eaves 4 and bounce off. The rainwater bounced from the eaves basket 4 to the indoor side hits the internal drainer 6 and falls to the eaves basket 4 through the upper cover 61. Further, the rainwater that bounces indoors and hits the auxiliary drainer 7 falls to the eaves wall 4 through the drainer plate part 72. As a result, the rainwater that has bounced back to the indoor side of the eaves 4 is collected and drained in the eaves 4 without entering the back side of the eaves 4.

  Rainwater bounced from the eaves basket 4 to the outdoor side hits the cover member 8 and flows into the eaves basket 4 from the cover member 8. Since the cover member 8 covers the joint portion on the outdoor side of the eaves cage 4 and the receiving member 40, rainwater does not enter these gaps.

  If guerrilla heavy rain occurs and the amount of rainfall increases, a large amount of rain water may splash at the eaves 4 or overflow from the eaves 4. On the other hand, the eaves tip structure according to the embodiment is provided with the internal drainer 6 and the auxiliary drainer 7, so that rainwater is difficult to enter the back side of the eaves wall 4, and even if it enters, It is guided to the lower draining plate portion 64 through the drainer 6. Since the lower draining plate portion 64 extends toward the water receiving groove 33 of the decorative member 3, rainwater is collected in the water receiving groove 33. For this reason, even if there is water that goes around to the back side of the eaves bowl 4, the eaves ceiling 201 is not wetted and can be drained from the water receiving groove 33 on the outdoor side.

  Furthermore, it is preferable that a drip wall 34 is connected to the decorative member 3 on the indoor side of the water receiving groove 33 and a preliminary groove 35 is provided. The hanging wall 34 is suspended downward from the indoor side edge of the water receiving groove 33. The preliminary groove 35 is formed in a groove shape at the lower end portion of the hanging wall 34 so as to protrude indoors, and is arranged in parallel with the water receiving groove 33. The preliminary groove 35 is disposed without being in contact with the eaves backing 26, and the edges of both are cut.

  As a result, the rainwater that circulates to the back of the eaves 4 is collected in the water receiving groove 33, and even if rainwater overflows from the water receiving groove 33, it overflows in the reserve groove 35 below it. Can receive rainwater. Therefore, it is avoided that the eaves ceiling 201 (eave back material 26) is wetted by rainwater. Further, the outer wall portion of the eaves backing material 26 is stored so as not to be seen from the appearance by the drooping wall 34 and the spare groove 35, and the finding dimension of the decorative member 3 is also kept small. Thereby, the designability of the external appearance of the collar 2 can be improved.

  As described above, according to the present invention, rainwater can be effectively collected and drained in the eaves wall 4, and the intrusion of rainwater into the back side of the eaves wall 4 is suppressed. In addition, discoloration, stains, and the like are prevented from occurring on the eaves ceiling 201, and an eaves tip structure excellent in durability and aesthetics can be obtained.

  In addition, in the fence 2, the roof frame 23, the roof base 21, and the roofing material 22 may be unitized and carried into the construction site in a state of being assembled in advance, or may be assembled at the construction site. . The roof frame 23, the roof material 22 and the like are metal members, but the present invention is not limited to this, and may be a member made of any material such as a wood material. Furthermore, the ridge 2 and the eaves ridge 4 are preferably provided with a water gradient, but may be provided substantially horizontally without being provided with a water gradient. The eaves rod 4 is not limited to the above-described configuration, and may be a round rod or the like, or may be a member that is subjected to corrosion resistance processing or is made of a metal plate material having corrosion resistance.

  The present invention can be suitably used as a building eaves structure.
