Description

  The present invention relates to an eaves bending joint that connects eaves at eaves corners of a house such as an entrance corner and an exit corner.

  Recently, in order to make the eaves of the house look good, the eaves of the same color or similar color as the eaves ceiling, roof, wall or window frame are attached to the eaves, and the eaves are attached to each other at the eaves corner. The eaves bending joint to be connected is also the same color as the eaves, and the members constituting the eaves are arranged in a uniform appearance color.

  For example, in the construction of the eaves, prepare many types of decorative sheets with different makeup in advance, select a decorative sheet with a texture corresponding to other components of the building at the construction site, and use this The eaves bowl is processed to have an appearance that is in harmony with the outer wall surface of the house (for example, see Patent Document 1).

  In addition, as a method of manufacturing a bent joint from an eaves rod, for example, as shown in FIG. 6, a pair of joint divided bodies 101 in which one end is cut obliquely at an angle of about 45 degrees in plan view, as shown in FIG. 101 is formed, the two split bodies are abutted with each other at the oblique end surfaces, and fixed on the inner surface side of the joint portion through a resin joint body 102 formed by outsert molding, thereby forming an integral bent joint.

  As mentioned above, if the eaves and the outer wall of the house are unified in a harmonious color and pattern, the appearance of the eaves will be better, but the work of processing the eaves surface at the construction site will be troublesome. In particular, the operation of attaching the decorative sheet to the surface of the eaves bending joint that connects the eaves to each other at the eaves corner is very troublesome and time-consuming because the bending joint is bent. In addition, there is a problem that the quality is not constant unless the person is proficient in processing work.

  In addition, the method of manufacturing the bent joint by joining the pair of joint divided bodies 101, 101 has the advantage that it can be molded using a ready-made resin eaves, but the joining process by outsert molding is complicated, In addition, the eaves made of resin-coated steel sheet cannot be used because the end face of the steel sheet is exposed and is easily corroded when it is cut, resulting in problems in appearance and durability. In the first place, since the stress accompanying the expansion and contraction of the eaves is concentrated on the bent joints installed at the corners of the eaves of the house, it is only necessary to fix the two joint divided bodies 101 and 101 through the resin joints 102. It has poor rigidity and has a problem with durability.

  In view of such problems of the prior art, the present invention is configured by using a resin-coated steel plate to form a bent joint having an external appearance that is integrally connected with the same color and pattern as the eaves, and has rigidity and durability. It is an object to provide an excellent eaves bending joint.

  In order to solve the above-mentioned problem, the eaves bending joint of the present invention is a bending joint A for connecting eaves to each other at the corner of the eaves of a house, and is obtained by bending a resin-coated steel plate whose surface is covered with a decorative sheet. A joint wall 1a, 1a having a bottom wall 11 bent in a substantially L-shape and inner and outer walls 12, 13 rising upward from the inner and outer edge portions of the bottom wall 11 to which eaves B are connected at both ends. The joint body 1 having a substantially U-shaped longitudinal section is formed, and the edges of the bottom wall 11, the outer wall 12 and the inner wall 13 are inward at the ends of the joint parts 1 a and 1 a of the joint body 1. Both joint portions on the back side of the overlapped portions 1b and 1b are provided with the lining steel plate 2 provided on the upper surface with the overlapped portions 1b and 1b formed by folding and the stopper pieces 20 with which the end portions of the eaves rod B are engaged. It has a structure that is attached to the inner surface of 1a and 1a and integrated. The one in which the features.

  According to this, since the edge of the bottom wall 11, the outer wall 12, and the inner wall 13 on the opening side of the joint part 1a is folded back inward to form the overlapping part 1b, the appearance of the joint part 1a on the opening side Will be better. In addition, the joint portion 1b is reinforced by the superposed portion 1b and the lining steel plate 2 attached to the inner surface of the joint portion 1a, thereby increasing the rigidity and improving the durability. Further, when the eaves B is connected to the eaves bending joint A, the stopper piece 20 raised from the lining steel plate 2 is positioned, and the connection position of the eaves B can be made constant.

  Moreover, in the said structure, the joint main body 1 is formed by positioning the joint part which face | matched the edge parts of the resin-coated steel plate on the diagonal line which connects the inner corner part of the bottom wall 11, and an outer corner part, The said joint part It can be set as the structure which attached the lining steel plates 2 and 3 to the inner surface. If it does in this way, the structure of the bending joint A will be simple and simple, and it will become easy to bend, and the outer wall 12 which stands | starts up along the outer edge of the bottom wall 11 will continue integrally, and rigidity will improve markedly.

  Since the eaves bending joint A of the present invention is formed by bending a resin-coated steel sheet, the rigidity and durability are remarkably superior to those of conventional resin bending joints. In addition, since the eaves bending joint A is integrated with the eaves B and exhibits the decoration effect of the eaves, it is possible to bring out a high-class feeling.
