Description

  The present invention relates to an eaves-rod outer bending joint that connects the ends of eaves-ridges arranged orthogonally at the protruding corners of the eaves at right angles.

  When attaching the eaves to the eaves, an eaves outer bending joint is known as connecting the ends of the eaves arranged orthogonally at the protruding corners of the eaves at right angles. In the eaves corners, eaves eaves bending joints are used for the right angle connection between the eaves eaves ends. These eaves eaves bending joints have a substantially L-shape in plan view, In general, a fitting portion at the end portion of the eaves is formed.

  Among such eaves-curved joints, the joints with the eaves are inconspicuous, and the eaves are hardly visible in the appearance, and seem to be eaves bent at a right angle. An eaves-curved joint that has been devised so that a sense of unity appears is known (Patent Document 1).

  In the eaves bending joint described in Patent Document 1, a fitting portion is extended from both ends of a substantially L-shaped joint body in plan view, and the outer peripheral surface of the fitting portion is a peripheral wall (bottom wall, front) of the eaves. A step portion is formed between the joint body and the fitting portion.

Therefore, when the ends of the eaves are connected to each other at right angles using the eaves bending joint, when the fitting part is fitted inside the eaves end, the outer peripheral surface of the fitting is the peripheral wall of the eaves The outer peripheral surface of the joint body and the outer peripheral surface of the eaves can be arranged substantially flush with each other. The joint between the eaves and the eaves is inconspicuous, and the eaves are not visually recognized as being connected by eaves bent joints, and a sense of unity appears as if the eaves are bent at a right angle. .

  However, although it is an eaves bending joint that makes the construction appearance as described above good, the dimension of the step between the joint body and the fitting part is usually the front wall part, bottom wall part and rear wall of the joint body. Since the eaves are generally made of synthetic resin, they are deformed by being heated and expanded by sunlight, and this deformation is likely to occur especially on the front and bottom walls of the eaves. When the outward bulge occurs in the wall portion and the bottom wall portion, the front wall portion and the bottom wall portion of the eaves ridge project outward from the joint body of the eaves bend joint, and the end surface of the eave ridge end portion is exposed. Such exposure of the end face of the eaves edge part due to the deformation of the eaves is a big problem in the above-mentioned eaves bending joint, which mainly improves the appearance of construction.

  The present invention has been made in view of the circumstances as described above, and prevents the end face of the eaves edge from being exposed even if the eaves is deformed and the front wall and the bottom wall are swollen. An object of the present invention is to provide an eaves bend joint that can maintain a good appearance.

  In order to solve the above-mentioned problem, the eaves bend outer joint of the present invention has a substantially square shape in plan view, is formed from a front wall portion, a bottom wall portion, and a rear wall portion, and has a substantially U-shaped cross section. From the both ends of the joint body toward the outside of the joint body, the outer peripheral surface is located inside the outer peripheral surface of the joint body, and a fitting portion is formed with a step formed between the joint body and the fitting portion. Are fitted inside the end of the eaves so that the ends of the eaves arranged orthogonally at the protruding corners of the eaves are connected at right angles, and the outer peripheral surface of the joint body and the outer peripheral surface of the eaves In the eaves outer bending joint to be arranged in one, the step on the intermediate side between the upper end and the lower end of the front wall of the joint body intersects the upper end and the bottom wall of the front wall of the joint body. Larger than the step on the periphery side of the corner, and the middle side between the front and rear ends of the bottom wall of the joint body Step is, it is characterized in that greater than the step of the front wall portion and intersect the corner portion near side and rear wall and intersecting the corner portion near the side.

  According to the present invention described above, the step around the intermediate portion between the upper end and the lower end of the front wall portion of the joint body intersects the upper end side and the bottom wall portion of the front wall portion of the joint body. The step on the intermediate side between the front and rear ends of the bottom wall portion of the joint body is larger than the step on the corner periphery side intersecting with the front wall portion and the corner portion periphery side intersecting with the rear wall portion. Therefore, even if deformation occurs in the eaves and the middle part of each of the front wall part and the bottom wall part of the eaves swells outward, a large step on the middle part side in the front wall part and the bottom wall part of the joint body The front wall portion and the bottom wall portion where the eaves swells can be stored within this step, and the end surface of the eaves ridge end portion is not exposed. A good appearance can be maintained.

  FIG. 1 is a perspective view showing an embodiment of an eaves bend joint according to the present invention. 2 and 3 are a plan view and a front view as viewed from the arrow of the eaves-rod outer joint shown in FIG. 1, respectively. FIG. 4 is an enlarged view within a solid line A in FIG.

  As shown in FIGS. 1, 2, and 3, the eaves bend outer joint 1 of the present embodiment has a substantially square shape in plan view, and is formed from a front wall portion 2 a, a bottom wall portion 2 b, and a rear wall portion 2 c. The joint body 2 having a substantially U-shaped cross section is provided. In the joint body 2, the front wall portion 2 a has a substantially L-shape in plan view, and the outer wall extends from the lower end to the upper end so as to coincide with the shape of the front wall portion of the eaves hook to which the eaves hook bend joint 1 is connected. Curved to bulge out. An upper end edge 2a1 having a substantially L-shape in plan view of the front wall 2a has an outer surface 2a2 having a shape that matches the outer surface of the front ear at the upper end of the front wall of the eaves. The bottom wall portion 2b has a flat shape, extends horizontally from the lower end of the front wall portion 2a, and the rear wall portion 2c rises at a right angle from the rear end. The rear wall portion 2c is curved in a substantially quarter circle shape, and the height is substantially half of the front wall portion 2a.

  In addition, in the eaves bend joint 1, a fitting portion 3 extends from both ends orthogonal to the upper end edge 2 a 1 of the joint body 2 toward the outside of the joint body 2. The fitting part 3 is formed from the front wall part 3a, the bottom wall part 3b, and the rear wall part 3c similarly to the joint main body 2, and has a substantially U-shaped cross section.

A step 6 is formed between the joint body 2 and the fitting portion 3 and is located on the inner side of the outer peripheral surface 5 formed from the outer surface of the joint.

  In the fitting portion 3, the front wall portion 3 a is disposed on the inner side of the step 6 from the front wall portion 2 a of the joint body 2 corresponding to the inner surface of the front wall portion of the eaves and extends from the lower end to the upper end. Curved to bulge outward. The upper end is formed with a front ear portion 7 having a substantially U-shaped cross section that opens outwardly into which the front ear portion provided at the upper end of the front wall portion of the eaves is fitted. An engaging recess 8 having a substantially U-shaped cross section is formed at the lower portion of the portion 7 to engage with an inwardly protruding protrusion provided at the upper end of the front wall portion of the eaves. The outer edge of the upper piece portion 7a of the front ear portion 7 is not parallel to the length direction of the fitting portion 3, but is slightly inwardly inclined from one end on the joint body 2 side to the middle in the length direction of the front ear portion 7. And it inclines inward largely toward the outer side end of the fitting part 3 from the middle, and the notch part 9 is formed. The notch part 9 reduces the contact area with the front ear part of the eaves bowl when the fitting part 3 is fitted to the eaves edge part, and makes it easier to fit the front ear part of the eaves bowl into the front ear part 7. .

  The bottom wall portion 3b extends horizontally from the lower end of the front wall portion 3a, and is arranged above the level difference 6 by a dimension. The rear wall portion 3c rises at substantially the same height as the rear wall portion 2c of the joint body 2 at a right angle from the rear end of the bottom wall portion 3b. Further, the rear wall portion 3 c is arranged on the inner side by the dimension of the step 6 from the rear wall portion 2 c of the joint body 2. When fitting the fitting part 3 to the eaves edge part, the upper end of the rear wall part 3c is engaged with the lower end of the rear ear part provided in the upper end of the rear wall part of the eaves bowl. A locking piece 10 is horizontally extended from the upper end toward the inside slightly so as to enable stable engagement.

  The steps 6 are not evenly provided in the eaves bend joint 1. That is, as shown in FIG. 3, on the front wall portion 2a side of the joint body 2, the steps 6a and 6b of the corner portion periphery 2a4 intersecting with the lower portion 2a3 of the engaging recess 8 located at the upper end portion and the bottom wall portion 2b.

Further, on the bottom wall 2b side of the joint body 2, the dimensions s4 and s5 of the steps 6d and 6e of the corner periphery 2b1 that intersects the front wall 2a and the corner periphery 2b2 that intersects the rear wall 2c are the front of the eaves. The thickness s6 of the step 6f of the intermediate portion 2b3 between the front and rear ends is larger than the thickness of the bottom wall portion of the eave ridge, and the dimensions of the steps 6d and 6e. It is larger than s4 and s5.

  On the rear wall 2c side of the joint body 2, the step 6 can be made uniform in the vertical direction, or can be a step 6 having different dimensions depending on the same part as the front wall 2a.

  The fitting portion 3 is fitted to the end portion of the eaves rod arranged orthogonally at the eaves corner of the eaves, and the eaves rod outer bending joint 1 connects the end portions of the eaves rod at right angles. In order to improve the above, the fitting part 3 is provided with two grooves 11 for applying adhesive on the outer peripheral surface 4 side by side. The adhesive application concave groove 11 is formed from almost right below the engagement concave portion 8 of the front wall portion 3a of the fitting portion 3 to the substantially upper end of the rear wall portion 3c through the bottom wall portion 3b, and has a substantially V-shaped cross section. Have The adhesive is applied along the adhesive application groove 11.

  On the other hand, when the ends of the eaves are connected at right angles, the fitting part 3 is fitted inside the eaves end, so that when the adhesive has a surplus, the excess adhesive is fitted. There is a risk of leakage from the portion 3 to the joint body 2 side. Since leakage of excess adhesive deteriorates the construction appearance, an adhesive escape groove 12 is formed near the joint body 2 on the outer peripheral surface 4 of the fitting part 3. The groove for releasing adhesive 12 has a shallow strip shape, and, similar to the groove 11 for applying adhesive, the bottom wall portion from almost immediately below the engaging recess 8 of the front wall portion 3a of the fitting portion 3. It is formed up to substantially the upper end of the rear wall 3c through 3b. Therefore, although the generated surplus adhesive is likely to occur particularly when a large amount of adhesive is applied in order to further increase the connection strength, it can be received by the adhesive escape groove 12 and leaks to the joint body 2 side. Is prevented. In order to prevent the excess adhesive from leaking more effectively, in the eaves-skin bend joint 1 of the present embodiment, the adhesive auxiliary reservoir groove 13 is formed between the two grooves 11 for applying the adhesive in the fitting portion 3. It is formed on the outer peripheral surface 4 part. The adhesive auxiliary reservoir groove 13 has a substantially V-shaped cross section, like the groove 11 for applying adhesive, and is formed in the front wall portion 3a, the bottom wall portion 3b, and the rear wall portion 3c. On the other hand, the adhesive auxiliary accumulation groove 13 is suppressed to the height to the lower end portion in the front wall portion 3a and the rear wall portion 3c. It is possible to preliminarily receive the excess adhesive overflowing from the adhesive application concave groove 11 by the adhesive auxiliary reservoir groove 13. It should be noted that the adhesive auxiliary reservoir groove 13 can be used as an adhesive application groove as long as there is room for the adhesive relief groove 12 to receive the adhesive.

  And in the eaves hook outer bending joint 1 of this embodiment, the guide piece 14 is standingly arranged by the upper end of the corner part 2c1 in the rear wall part 2c of the coupling main body 2.
