  However, when it rains, rainwater tends to enter the inside from the joint. And the rainwater which infiltrated collects in a corner block or its peripheral part. As a result, there was a problem that even after raining, rainwater that had accumulated in the corners continued to drip from the corners.

  For this reason, a caulking process is also performed on the joint. However, the caulking work is not always performed stably, and there is no guarantee that a good drainage is maintained for a long period of time.

  This invention makes it the subject to eliminate the said trouble and to provide the corner dredging which can always drain a rainwater well.

  In order to solve the above-mentioned problem, the invention according to claim 1 is characterized in that the ridge body provided on one wall surface and the ridge body provided on the other wall surface constituting the corner portion of the building are each formed in a hollow shape and at one end portion. And the two heel bodies are connected to each other by a butt joint through a corner block, and a ridge groove portion is provided on the upper surface of the corner block at a position corresponding to the joint portion of the heel body. To do.

  According to a second aspect of the present invention, in the first aspect, a wall portion for forming a hollow portion is formed inside along the longitudinal direction of the heel body, and a ridge groove portion of the corner block is formed in the wall portion. The wall part of the part which interferes is characterized by having cut off the edge part by the side of cutting.

  A third aspect of the present invention is characterized in that, in the first or second aspect, a drainage groove is formed downward at the tip of the joint portion of the main body.

  The invention according to claim 4 is characterized in that, in claim 3, the tip of the groove groove of the corner block is arranged before the tip of the joint portion of the flange body.

  According to the invention which concerns on Claim 1, while one end part of two hollow eaves bodies provided in the corner part of a building is made into a toe, these eaves bodies are mutually connected by a toe joint via a corner block Since the upper surface of the corner block is provided with the ridge groove portion at a position corresponding to the joint portion of the ridge body, when rainwater enters inside from the joint portion or the like, it falls into the ridge groove portion and is drained. Therefore, rainwater does not accumulate on the corner block or its peripheral portion and continues to drip from the corner portion even after raining. Moreover, since it is not based on a caulking process, rainwater can always be drained well over a long period of time.

  According to the invention according to claim 2, in order to form a hollow portion in the interior of the heel body, a wall portion may be formed along the longitudinal direction of the heel body. Since the end of the wall part is also abutted, the wall part crosses the ridge groove part of the corner block, so the flow of rainwater flowing in the ridge groove part is stopped, but the end part on the side of the above-mentioned wall part is cut off, Rainwater is not blocked and drainage is performed smoothly.

  According to the invention of claim 3, since the drainage groove is formed downward at the tip of the joint portion of the ridge body, rainwater is drained from the tip of the ridge groove and does not travel down the wall. Do not pollute.

  According to the invention which concerns on Claim 4, since the front-end | tip of the trough groove | channel of a corner block is arrange | positioned before the front-end | tip of the junction part of the said scissors main body, a corner block is not exposed outside from a drainage groove.

  FIG. 1 is a cross-sectional view of a corner ridge according to the present invention, and FIG. 2 is a vertical cross-sectional view thereof.

  In the figure, reference numeral 1 denotes a window portion, and this window portion 1 is formed with an opening by a pillar 2 of a building frame, a window base 3 and a lintel 4, and is formed between an upper frame 5 and a lower frame 6 of the window portion 1. The shoji 7 is arranged in the. 8 is a frame, 9a is an exterior material, and 9b is an interior material.

  A corner ridge is attached to the upper part of the corner of the window. The corner ridge is formed by joining two ridge main bodies 10 provided between the corner portions. The ridge body 10 includes a horizontal lower surface plate 11 and an inclined upper surface plate 12 and an intermediate wall portion 14. It connects with the wall part 15 of the front end side, and forms two hollow parts a and b inside. The top end of the upper surface plate 12 is bent downward. A groove 17 is formed between the tip of the bent portion 16 and the tip of the lower surface plate 11. Further, the base portion of the upper surface plate 12 is continuously formed with a mounting portion 18 standing upward and a receiving portion 20 bent in an L shape at the upper portion thereof. In addition, the main body 10 has the mounting portion 18 fixed to the window base 3 with screws. 21 is a cap material that hides the screw head. The receiving part 20 is provided with a sealing material 22. Reference numeral 23 denotes a screw hole, which is used to stop the screw when the cap 36 (see FIGS. 1 and 3) is fixed to the small edge of the bag main body 10 or when a corner cover 37 described later is fixed.

  Next, as shown in FIGS. 3 and 4, the two scissors main bodies 10 provided across the corner portion are joined and connected via a corner block 24.

  That is, the end portion 25 on the corner portion side of the bag main body 10 is cut at 45 degrees.

  The corner block 24 is made of synthetic resin and has a substantially square shape. The corner block 24 fits inside the base wall 13 and the tip wall 15 between the top plate 12 and the bottom plate 11. Is formed. A base part 26 is formed in the central part, slightly closer to the corner on the base side. The tip side is lowered one step through a step 27 in order to avoid interference with the screw hole 23 of the bag main body 10, and continues to the bottom surface portion 28. And the said base part 26 is formed with the gutter | groove 30 on the diagonal of the corner | angular corner part of a base side and a front end side, the base side is closed and the front end side is open | released.

  Further, one corner is cut out at a right angle, and a rising piece 31 is formed in an L shape from the cutout. A flow stop 32 is formed on both sides of the other corner.

  Further, the base portion 26 is formed with a clearance groove 33 that avoids interference with the intermediate wall portion 14 of the bag main body 10.

  Corresponding to the configuration of the corner block 24, as shown in FIG. 5, a notch 34 for passing the rising piece 31 of the corner block 24 is provided at the base of the top plate 12 of the upper surface plate 12 of the main body 10. Is formed. Further, the edge portions 14a and 15a on the cut-out side of the intermediate wall portion 14 and the tip wall portion 15 are cut off.

  In the above-described configuration, the corner block 24 is fitted into each of the two scissors main bodies 10 and is joined to the joint. At this time, a sealing material 35 is pasted on the rear surface of the rising piece 31 of the corner block 24 (for water tightness), and is exposed to the front side of the mounting portion 18 through the notch 34 of the main body 10. To do. Thereby, the bag main body 10 is joined stably. Further, the intermediate wall portion 14 of the rod main body 10 enters the escape groove 33, but does not reach the groove groove 30 because the front end portion is cut away. Further, the step 27 of the corner block 24 is engaged in front of the screw hole 23 of the heel body 10, and the end of the corner block 24 is engaged with the back side of the wall portion 15 on the distal end side of the heel body 10. As described above, the two scissors main bodies 10 are joined via the corner block 24 and are integrally connected.

  In addition, it is preferable to attach the corner cover 37 to the upper part of the junction part of the two heel main bodies 10, as FIG. At the tip of the corner cover 37, an engagement piece 38 that engages with the outer side surface of the bent portion 16 on the tip side of each heel body 10 is formed. Thereby, it is possible to prevent the two main body 10 from moving in the opening direction.

  According to the above-described configuration, one end of the two hollow scissors main bodies 10 provided at the corners of the building is cut off, and the scissors main bodies 10 are connected to each other through the corner blocks 24 and connected to each other. Since the upper surface of the corner block 24 is provided with the ridge groove 30 portion at a position corresponding to the joint portion of the heel body 10, when rainwater enters inside from the joint portion or the notch portion of the base portion of the upper surface plate 12, It falls into the 30th groove. Since the base side of the ridge groove 30 is closed, the rainwater inside moves to the tip side. At this time, since the middle wall portion 14 and the front wall portion 15 of the main body 10 are notched, the rainwater does not interfere with the flow of the rainwater, and the rainwater continues to the bottom surface portion 28 that continues to the main groove 30. Flows in. Here, the rainwater spreads laterally and flows, but is blocked by the flow stop 32, and therefore flows further from the notch of the wall portion 15 on the distal end side to the distal end. Since there is no bottom plate 11 at the tip and a groove 17 is formed, the groove 17 becomes a drainage groove, and drains immediately from here. Therefore, rainwater does not accumulate in the corner block 24 or its peripheral portion and does not continue to drip from the corner portion even after raining. Moreover, since it is not based on a caulking process, rainwater can always be drained well over a long period of time.

  In addition, in order to form a hollow portion inside the rod main body 10, an intermediate wall portion 14 and a tip-side wall portion 15 are formed along the longitudinal direction of the rod main body 10. Since the end on the side is cut off, rainwater is not blocked and drainage is performed smoothly.

  Further, as described above, the drainage groove 17 is formed downward at the tip of the joint portion of the main body 10, so that rainwater is drained from the front end of the groove 30 and does not travel down the wall. Don't get dirty.

  Furthermore, since the tip of the ridge groove 30 of the corner block 24 is disposed in front of the tip of the joint portion of the ridge body 10, the corner block 24 is not exposed to the outside from the drain groove 17.
