Description

  The present invention relates to a structure for attaching a decorative material for attaching a decorative material to a building frame.

  In recent years, there has been a tendency to emphasize the concept of using a building frame in a comfortable state over a long period of time, and it is widely practiced to inspect, inspect, and repair the details of the building frame as necessary. An important part where the building frame is inspected and inspected is a joint portion represented by a connecting portion of the upper and lower floors of the building frame. This joint is the part formed by embedding caulking material in the gap of the building frame to prevent the internal structure from being corroded by rainwater entering the gap of the building frame. That is.

  Usually, this joint is covered with a decorative material such as a waistline so as not to impair the appearance of the building. Therefore, it is necessary to remove the cosmetic material at the time of inspection / inspection and then attach it again. As an attachment structure of a decorative material that realizes such attachment / detachment, for example, there is one disclosed in Japanese Patent Application Laid-Open No. 2003-3642 (Patent Document 1). Hereinafter, the attachment structure of the decorative material disclosed in Patent Document 1 will be described with reference to the drawings.

  FIG. 7 is a cross-sectional view showing the decorative material mounting structure disclosed in Patent Document 1, and FIG. 8 is an enlarged cross-sectional view of a mounting portion between the decorative material and the mounting bracket. As shown in FIG. 7, the decorative material 110 is attached to the wall surface of the building housing 130 via the mounting bracket 120 in order to hide the joint portion 131 of the building housing 130. The mounting bracket 120 has a base part 121 and a receiving part 122 and is attached to the building housing 130 by screws 140. The decorative material 110 has a protruding portion 112 projecting from the main body 111 toward the building housing 130, and the protruding portion 112 is inserted into the receiving portion 122 of the mounting bracket 120, whereby the decorative material 110. Is attached to the building housing 130.

  As shown in FIG. 8, in a state where the protruding portion 112 of the decorative material 110 is inserted into the receiving portion 122 of the mounting bracket 120, the tip 112 a of the protruding portion 112 fits into the bent portion 122 b of the receiving portion 122. Thus, the decorative material 110 is held by the mounting bracket 120 with a predetermined fitting force. From this state, by pulling the decorative material 110 in the direction of the arrow in the figure, the bent portion of the receiving portion 122 and the standing wall portion 122c are pushed outward by the tip 112a of the protrusion 112, and the tip 112a of the protrusion 112 is The decorative material 110 is removed from the mounting bracket 120 by climbing over the top of the bent portion 122b of the receiving portion 122.

By adopting the decorative material mounting structure described above, it becomes possible to remove the decorative material and to easily inspect, inspect and repair the building frame. Further, even after the inspection / inspection or repair is completed, the attached decorative material can be attached again to the building frame via the mounting bracket, which is economically superior.
Japanese Patent Laid-Open No. 2003-3642

  However, the decorative material mounting structure described above is intended to be applied to cosmetic materials made of plastic materials such as plastic, and is made of ceramic materials such as cement. When applied to a decorative material, there is a problem that wobbling occurs in the decorative material because it is difficult to secure the mounting strength. This is because it is difficult for the decorative material made of ceramic materials to produce subtle dimensional accuracy compared to the decorative material made of resin materials, and it is relatively heavy. When the structure is adopted, the weight of the decorative material is concentrated on the locking piece on the lower side of the receiving portion, and the locking piece is warped downward by the weight. In order to suppress this warpage, it is conceivable to manufacture the mounting bracket with a material having high rigidity. However, in this case, there arises a disadvantage that the attachment and detachment cannot be easily performed.

  In the mounting structure of the decorative material that can be attached and detached, it is necessary to ensure sufficient mounting strength so that the decorative material does not easily fall off in the mounted state. It is necessary that the removal can be easily performed so that the burden of the removal work is reduced. For cosmetics made of relatively light materials and exhibiting high dimensional accuracy, it is not difficult to meet these conflicting requirements, but it is difficult to achieve subtle dimensional accuracy. For a decorative material made of a relatively heavy material, it is very difficult to realize a mounting structure that satisfies this requirement.

  Therefore, the present invention provides a mounting structure for a cosmetic material that can achieve both a sufficient mounting strength for the building frame and ease of removal work even in a decorative material formed using a ceramic material or the like. The purpose is to do.

  The attachment structure of the decorative material based on this invention attaches a decorative material to a building frame with an attachment metal fitting. The decorative material is provided with a recess formed on the mounting surface facing the mounting bracket side so that the opening area in the back side portion is wider than the opening area in the entrance portion. The mounting bracket includes a base that is attached to the building frame, and a pair of locking pieces that are erected from the base toward the decorative material side. Each of the pair of locking pieces includes a standing wall portion that rises from the base portion and a curved portion that is located at the tip of the standing wall portion and swells in opposite directions. The pair of curved portions are inserted to the back side portion through the entrance portion of the concave portion, whereby the decorative material is fitted to the mounting bracket. Further, the decorative material is supported from below by at least one of the pair of standing wall portions.

  By comprising in this way, since a decorative material comes to be supported in the state which surface-contacted by the standing wall part, it comes to add to a locking piece in the state to which the weight of the decorative material was disperse | distributed. For this reason, even when applied to a decorative material made of a ceramic material or the like, warping of the locking piece in a state where the decorative material is attached is suppressed, and wobbling of the decorative material after the attachment is eliminated. . Therefore, it is possible to achieve both sufficient attachment strength and ease of removal work.

  In the attachment structure for a decorative material according to the present invention, it is preferable that each of the pair of locking pieces is formed by cutting and bending the base portion.

  Thus, by forming each of the pair of locking pieces by bending, it becomes possible to manufacture the mounting bracket with a single metal plate, and it is possible to manufacture the mounting bracket inexpensively and easily. It becomes possible.

  In the decorative material mounting structure according to the present invention, it is preferable that the pair of locking pieces are arranged so as to be shifted laterally so as not to face each other.

  By comprising in this way, it becomes possible to ensure the contact area of a makeup | decoration material and a mounting bracket still larger, and the curvature of a latching piece comes to be suppressed further. In addition, there is an advantage that it is easy to manufacture the mounting bracket by bending a single metal plate.

  ADVANTAGE OF THE INVENTION According to this invention, coexistence with sufficient attachment intensity | strength with respect to a building frame and the ease of removal work is implement | achieved even if it exists in the decorative material formed using materials, such as a ceramic industry type | system | group.
