Description

  The present invention relates to a mounting structure for a decorative material for mounting a decorative material to a building structure with a mounting bracket.

  Conventionally, a decorative material may be attached in order to improve the aesthetics of an outer wall of a building or a gust of wind. Although there is still a method for attaching the decorative material directly by screwing the decorative material to the attached portion with a screw or a nail, particularly in recent years, the decorative material attachment tool is attached to the base surface which is the attached portion. It is shifting to a method of attaching a cosmetic material via a cosmetic material fixture.

  As a conventional example of such a cosmetic material fixture (see Patent Document 1), for example, as shown in FIG. 9, a plate-like shape that is provided so as to face each other and the substrate portion 111 is raised from the substrate portion 111. A substrate composed of a base end portion 112a, a guide portion 112b that is bent so as to form an obtuse angle with respect to the plate-like base end portion 112a and extends obliquely inward, and a tongue piece cut out from the plate-like base end portion 112a And an engaging portion 112c extending obliquely outward so as to approach the portion 111.

  FIG. 10 shows an example in which the decorative material 120 is actually attached to the decorative material mounting tool 110. The front end of the engaging portion 112c gets over the end of the guide surface 123b of the decorative material 120, and the engaging portion 112c engages and contacts the engaging surface 123a to fix it.

  Moreover, FIG. 11 has shown the example (refer patent document 2) of the other cosmetic material fixture 210. FIG. In this conventional example, the base plate portion 211, a pair of support portions 212a standing on the decorative material mounting side of the base plate portion 211, the leg portions 212b folded back from the tip portions of the support portions 212a, and the tip portions of the leg portions 212b are formed. Engaging portion 212c.

  FIG. 12 shows an example in which the decorative material 220 is actually attached to the decorative material fixture 210 having such a configuration. The engaging portions 212c of the respective locking and fixing portions 212 of the decorative material mounting fixture 210 are engaged and abutted with the respective engaging surfaces 226 formed in a tapered shape provided on the back surface side of the decorative material 220 and fixed.

  The conventional attachment structure of each cosmetic material described above simultaneously achieves both the backlash of the cosmetic material in the front-rear direction of the cosmetic material and the prevention of the cosmetic material from being detached from the cosmetic material rather than the detachability of the cosmetic material with respect to the cosmetic material fixture. This is a technology intended for However, in the disclosed technique of Patent Document 1, when the engaging portion 112c that is engaged and abutted on the engaging surface 123a is detached, the cosmetic material itself is detached from the cosmetic material fixture as it is. It will be. Similarly, in the disclosed technique of Patent Document 22, when the engaging portions 212c of the respective locking and fixing portions 212 of the cosmetic material fixture 210 are disengaged from the respective engaging surfaces 226, the cosmetic material itself is similarly used as the cosmetic material. It will come off from the fixture.

  In other words, the disclosed techniques of Patent Documents 1 and 2 are all responsible for preventing the cosmetic material from being detached from the cosmetic material fixture in one step via the engaging portion. If such a one-step removal prevention mechanism is disengaged, the cosmetic material is immediately detached, which makes it difficult to more firmly suppress the removal of the cosmetic material.

  In addition to this, the decorative material attached to the decorative material fixture may be displaced in the depth direction of the paper surface of FIGS. When such a deviation of the cosmetic material occurs, it is desirable to eliminate as much as possible because it may cause various obstacles to smooth construction. However, in Patent Documents 1 and 2 described above, which prevent the cosmetic material from being detached from the cosmetic material mounting tool in one stage, there is a problem in that such a shift in the depth direction on the paper surface cannot be firmly prevented.

  Therefore, the present invention has been devised in view of the above-described problems, and the object of the present invention is to prevent the removal of the cosmetic material from the mounting bracket in two or more stages, thereby further preventing the removal. An object of the present invention is to provide a mounting structure for a decorative material that can be realized steadily.

  In order to solve the above-described problems, a decorative material mounting structure according to the present invention is a decorative material mounting structure in which a decorative material is attached to a building structure with a mounting bracket. The decorative material has a diameter with a large tip. A protruding piece having a large portion and an intermediate portion whose diameter is small from the large diameter portion to the base is projected from the back side of the decorative surface, and the mounting bracket is a substrate fixed to the building structure, An engaging piece raised in a direction substantially orthogonal to the substrate, and the engaging piece is curved so as to form a convex outward, and the convex engaging part And a guide part that is inclined inwardly and extended in a direction away from the substrate, and a claw part that is cut out from the guide part and extends toward the convex locking part is formed. In the cosmetic material from the outer surface of the claw part in the mounting bracket After the engagement piece is elastically displaced inward by being pressed by the large-diameter portion, the convex locking portion is latched to the large-diameter portion in a state of being biased outward based on the elastic restoration. Furthermore, the tip of the claw portion is pressed and locked to the intermediate portion based on the urging force.

  In order to solve the above-described problems, a method for attaching a decorative material according to the present invention includes a method for attaching a decorative material to a building structure by using a fitting, and a large diameter portion having a large tip and a diameter thereof. A projecting piece having a projecting piece having a small diameter from the most part to the base and projecting from the back side of the decorative surface, a substrate, and a member raised in a direction substantially orthogonal to the substrate The engaging piece has a convex locking portion that is curved to form a convex outward and is inclined inwardly from the convex locking portion to extend away from the substrate. And a mounting bracket formed with a claw portion cut out from the guide portion and extending toward the convex locking portion, and attaching the board to the building structure. Next, from the outer surface of the claw portion of the mounting bracket to the decorative material After the engagement piece is elastically displaced inward by being pressed by the large-diameter portion, the convex locking portion is latched to the large-diameter portion in a state where the convex engagement portion is urged outward based on the elastic recovery. Further, based on the urging force, the tip of the claw portion is pressed against the intermediate portion to be locked.

  According to the present invention having the above-described configuration, first, in the first stage, the mounting bracket and the decorative material are fixed to each other through the locking of the convex locking part and the large-diameter part. It is possible to fix the mounting bracket and the decorative material to each other through the engagement between the portion and the intermediate portion. For this reason, it is possible to take the prevention of the detachment of the decorative material from the mounting bracket in two stages, and it is possible to more steadily realize the prevention of the detachment.

  In addition, according to the present invention, the cosmetic material can be prevented from being detached from the mounting bracket in two stages, so that the cosmetic material once attached to the mounting bracket is more securely prevented from being displaced. It becomes possible. As a result, smoother construction can be performed.

  Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.

  FIG. 1 (a) is a front view of a mounting bracket 2 constituting a decorative material mounting structure to which the present invention is applied, FIG. 1 (b) is a plan view thereof, and FIG. 1 (c) is a side view thereof. It is. 2 is a partial perspective view of the mounting bracket 2, and FIG. 3 shows the decorative material 3 constituting the decorative material mounting structure.

  The mounting bracket 2 is obtained by cutting and processing a metal flat plate having a thickness of about 0.2 to 2.0 mm, and stands in a substantially rectangular substrate 11 and a direction substantially orthogonal to the substrate 11. A pair of engagement pieces 12 are provided so as to be opposed to each other, and a fixture insertion hole 13 formed in the substrate 11 is provided.

  The engaging piece 12 is a convex locking part 21 that is curved so as to form a convex outward, and a guide part 22 that is inclined inward from the convex locking part 21 and extends away from the substrate 11. Further, a claw portion 23 that is cut out from the guide portion 22 and extends toward the convex locking portion 21 is formed. In addition, a portion raised from the substrate 11 to the convex locking portion 21 in a direction substantially orthogonal to the substrate 11 is hereinafter referred to as an upright portion 24.

  More specifically, as shown in FIG. 2, the convex locking portion 21 includes a shelf portion 21 a that is bent outward with respect to the raised portion 24, and a direction away from the substrate 11 from the outermost side of the shelf portion 21 a. And an extended outer peripheral portion 21b. However, it is not essential that the shelf portion 21a and the outer peripheral portion 21b are clearly distinguished from each other, and the shelf portion 21a and the outer peripheral portion 21b may be configured to be integrally curved with each other. It should be noted that the meaning of the curvature that forms a convex outward defined in the convex locking portion 21 is based on the premise that R is provided, but the curvature radius of R is any It may be.

  As shown in FIG. 2, the guide portion 22 has a hole 27 cut out at the center. The hole portion 27 is originally cut to raise the claw portion 23, and may have any shape. The guide portion 22 may be curved so as to protrude outward in a front view, or may constitute a linear surface without being curved. The guide portion 22 has a tip portion 28 whose tip is bent inward. As shown in FIG. 1B, the distal end portion 28 may have a shape that is gradually reduced in diameter as it approaches the distal end, whereby the angle formed with the guide portion 22 can be easily adjusted. It is possible. The distal end portion 28 is curved so as to form an obtuse angle with the guide portion 22, and R constituting the curvature may be any radius of curvature including zero.

  The hole portion 27 is formed by punching the claw portion 23 from the periphery of the claw portion 23 with a space therebetween. As shown in FIG. 1A, the claw portion 23 may be configured such that the claw portion 23 is raised slightly upward from the guide portion 22 in a front view. The claw portion 23 may be configured to be linear in a plan view.

  The decorative material 3 is directly exposed to the outside of the building structure indoors and outdoors, and is projected from the decorative surface 36, which may be painted or various three-dimensional patterns, and the back surface 37 side of the decorative surface 36. And a protruding piece 30. The projecting piece 30 has a large-diameter portion 31 whose tip is made large in diameter and an intermediate portion 33 whose diameter is small from the large-diameter portion 31 to the root 32. According to the example of FIG. 3, the large-diameter portion 31 of the protruding piece 30 is formed substantially vertically inward with respect to the intermediate portion 33 so that the diameter rapidly increases in plan view from the intermediate portion 33 to the large-diameter portion 31. And a reduced diameter surface 31b that is gradually reduced in diameter from the locking portion 33 to the lower end portion 31c. The decorative material 3 is made of, for example, an inorganic material such as cement, or a resin material.

  Next, a method of actually constructing a mounting structure for a decorative material using the mounting bracket 2 and the decorative material 3 having the above-described configuration will be described.

  First, the mounting bracket 2 is fixed to the base wall 40 as shown in FIG. This fixing is performed by inserting a fixture 41 such as a drill screw into the fixture insertion hole 13 formed in the substrate 11 and driving the fixture 41 against the base wall 40. Next, the decorative material 3 is attached to the mounting bracket 2. At this time, the attachment to the mounting bracket 2 is executed with the back surface 37 facing the mounting bracket 2 and the decorative surface 36 facing the outside.

  First, as shown in FIG. 5, the reduced diameter surface 31 b in the large diameter portion 31 of the decorative material 3 is brought into contact with the outer surface of the claw portion 23 in the mounting bracket 2. As a result, the claw portion 23 of the mounting bracket 2 is pressed from the outside by the large-diameter portion 31 of the decorative material 3, and the engagement piece 12 itself is elastically directed inward as shown by the arrow direction in the figure. Will be displaced.

  When the decorative material 3 is further pushed in, the amount of elastic displacement to the inside of the engagement piece 12 further increases as shown in FIG. When the decorative material 3 is further pushed in from this state, as shown in FIG. 7, the protruding piece 30 in the decorative material 3 and the engaging piece 12 in the mounting bracket 2 can be engaged with each other. . More specifically, in this engaged state, firstly, a state in which the engaging portion 31a of the large-diameter portion 31 in the decorative material 3 is first engaged between the engaging portion 31a of the convex engaging portion 21 and the engaging portion 31a. It has become. In addition to this, the tip of the claw portion 23 is locked to the intermediate portion 33.

  Further, in the state of FIG. 7, after the engagement piece 12 is elastically displaced inward in the state of FIG. 6, the engagement piece 12 itself is urged outward based on its elastic recovery. . By this outward biasing, the convex locking portion 21 is first biased outward, and this is locked with the large-diameter portion 31, and the claw portion 23 of the claw portion 23 is based on the biasing. The tip is pressed and locked by the intermediate portion 33. By locking the members in the biased state, the mounting bracket 2 and the decorative material 3 can be firmly attached so as not to be separated from each other. In particular, when the tip of the claw 23 is pressed against the intermediate portion 33, the tip of the claw 23 can be brought into the intermediate portion 33. It is also possible to prevent the claw portion 23 from easily deviating from the intermediate portion 33 by this indentation.

  As described above, according to the present invention, in the first stage, the mounting bracket 2 and the decorative material 3 are fixed to each other through the locking of the convex locking part 21 and the large diameter part 31, and the second stage still remains. In this case, the fitting 2 and the decorative material 3 can be fixed to each other through the engagement between the claw portion 23 and the intermediate portion 33. For this reason, the prevention of detachment of the decorative material 3 with respect to the mounting bracket 2 can be performed in two stages, and the detachment prevention can be more steadily realized. Further, even when a large force is applied, such as wind pressure due to a typhoon or vibration due to a large earthquake, it is possible to prevent the separation.

  In addition to this, according to the present invention, the cosmetic material 3 once attached to the mounting bracket 2 can be prevented from being detached from the mounting bracket 2 in two stages. It is possible to more firmly prevent sag. As a result, smoother construction can be performed.

  In the present invention, for example, as shown in FIG. 7, the distal end portion 28 at the distal end of the curved guide portion 22 may be pressed against the back surface 37 of the decorative material 3. As a result, the front end portion 28 of the mounting bracket 2 is pressed from the back surface 37 of the decorative material 3, and the contact position of the convex locking portion 21 with which the large-diameter portion 31 abuts becomes a fulcrum. As a result, the claw portion 23 can be warped further outward (in the y direction in FIG. 7). As a result, the claw portion 23 can be engaged with the intermediate portion 33 at the tip end in a state along the outer side. In particular, by engaging the tip of the claw 23 in a state of rising toward the intermediate portion 33, it is possible to exert a greater resistance to the force that tends to come out in the z direction in the figure. Become.

  Furthermore, according to the present invention, even when the above-described two-stage detachment preventing mechanism is disengaged, the locking portion 31a in the large-diameter portion 31 is locked to the tip of the claw portion 23 as shown in FIG. By doing so, complete detachment can be prevented. That is, since the detachment of the decorative material 3 can be prevented even through the mechanism shown in FIG. 8, it is possible to exhibit a total of three stages of detachment prevention functions.
