Description

  The present invention relates to a ceramics system in which a plurality of relatively large-sized building wall plates, such as tiles, wood, artificial wood, and stone, are provided in a plurality of horizontal engagement ridges at regular intervals in the vertical direction. The present invention relates to a mounting bracket that can be easily attached to a base material of a material.

  When building wall surfaces for buildings such as tiles are used to form the outer and inner walls of a building, the horizontal engaging projections are spaced at regular intervals in the vertical direction from the viewpoint of ease of construction and heat and weather resistance. In many cases, a base material of a ceramic material provided with a large number of multistages is used (Patent Documents 1 and 2).

  When the base material is used, an engagement recess that engages with an engagement protrusion of the base material is provided on the back surface of the building wall plate, and a springy clip is attached. The building wall plate is fixed to the base material by engaging the engaging recess formed on the back surface with the engaging protrusion of the base material and applying the spring force of the clip to the engaging portion.

  In order to employ the construction structure for building wall plates, it is necessary to provide engaging recesses on the back surface of the building wall plates as described above.

  However, since the engaging recess formed on the back surface of the wall surface plate for building becomes an inversely inclined surface (so-called undercut), the structure of the back surface of the wall surface plate for building becomes complicated, which increases the molding cost.

  In addition, there is a problem that the material cost is increased by forming the engaging recess on the back surface.

  In addition, construction is difficult in the case of a relatively large plate wall surface plate having a length in the vertical direction that spans a large number of engaging projections of the base material.

The example shown in FIG. 1 is of a large plate size having a length extending over 12 engaging projections 22.

  As shown in FIG. 1 and FIGS. 2 and 3 of a partially enlarged view thereof, the mounting bracket according to the present invention is used to mount the large-plate-sized building wall plate 24 to the base material 33. The mounting bracket 41 is divided.

  As shown in FIG. 4 as a whole, the lower mounting bracket 11 and the upper mounting bracket 41 are each attached to the center portion of the back surface of the building wall plate 24 and three left and right end portions.

  That is, as shown in FIG. 4, three lower mounting brackets 11 are mounted on the lower center portion of the rear surface of the building wall plate 24 and the lower left and right end portions, and the upper mounting bracket 41 is the building wall plate. Three are attached to the center part of the upper part of the back surface of 24 and the left and right end parts of the upper part.

  As shown in FIGS. 5 to 7, the lower mounting bracket 11 includes a combination of a mounting plate 12 made of metal such as steel and stainless steel and a plate spring 13.

  The mounting plate 12 is formed in a rectangular shape, and an engagement piece 14 having a constant width is provided at the upper end of the mounting plate 12 so as to be bent toward the back surface (see FIG. 1 and FIG. 3, the surface of the lower mounting bracket 11 with respect to the base material 26). It is done. The engagement piece 14 is inclined downward at a constant angle θ (about 55 °) so as to coincide with the inclination angle of the upper surface 32 of the engagement protrusion 29 of the base material 26 (see FIGS. 1 and 3). (See FIG. 6).

  On the mounting plate 12, four parallel reinforcing ribs 15 in the vertical direction are provided at predetermined intervals in the width direction at two portions, a portion along the left and right sides of the back surface and an intermediate portion. These reinforcing ribs 15 are pressed so as to protrude from the front side to the back side, and the back and front sides of the mounting plate 12 by these reinforcing ribs 15 are the intermediate part 12a and the left and right side parts 12b sandwiching the intermediate part 12a. , 12c. The intermediate portion 12a is the widest, and both side portions 12b and 12c are formed to have the same narrower width.

  A downward U-shaped notch 16 having an open lower end is provided at the lower end of the intermediate portion 12a. This notch 16 is formed widely so as to approach the ribs 15 present on the left and right sides thereof.

  The leaf spring 13 is formed to be slightly narrower than the width of the notch portion 16, and is bent in an L shape toward the back side at the lower end portion of the fixing portion 13a that reaches the lower end from approximately the middle in the vertical direction of the intermediate portion 12a. The elastic portion 13b. As shown in FIG. 6, the elastic portion 13b is provided with corrugated irregularities.

The leaf spring 13 is fixed to the intermediate portion 12a by burring in a state where the fixing portion 13a of the leaf spring 13 is applied to the back surface of the intermediate portion 12a and the position of the convex portion of the elastic portion 13b is held at a certain height. . The burring portion is indicated by reference numeral 17. The hole of the burring portion 17 is provided with an attachment hole 18 for screwing and fixing the attachment plate 12 to the architectural wall plate 24 (see FIG. 8) simultaneously when the material of the architectural wall plate 24 is wood or artificial wood. It has become.
The wall surface plate 24 of the embodiment of FIGS. 1 to 4 is a material such as a tile that cannot be screwed. Therefore, an adhesive is used to fix the mounting plate 12 and the wall surface plate 24 for building, and the mounting hole 18 Is not used.

  The plate spring 13 has a substantially lower half of the fixing portion 13a facing the width of the cutout portion 16, and against the external force p (see FIG. 6) in the pushing direction acting on the leading end of the elastic portion 13b. This gives a margin for elastic deformation to the back side by the thickness of.

The intermediate engagement piece 19 is provided by cutting and raising. The intermediate engagement piece 19 is bent toward the back side of the mounting plate 12 and is inclined downward with the same inclination angle as the inclination angle θ of the engagement piece 14. The protrusion height h of each intermediate engagement piece 19 from the mounting plate 12 is about half of the protrusion height H of the engagement piece 14.

  As shown in FIG. 8, the three mounting holes 18 are used when the lower mounting bracket 11 is fixed to the building wall plate 24 with mounting screws 28 or nails. When the building wall plate 24 is fixed by adhesion, the mounting hole 18 is not necessary. In the “claims”, the attachment holes 18 and the parts fixed by bonding are collectively referred to as “attachment portions”.

  The square hole 21 after cutting and raising the intermediate engagement piece 19 is formed larger than the area of the intermediate engagement piece 19, thereby reducing the weight of the mounting bracket 11. Considering the ease of cutting and raising, both ends of the intermediate engagement piece 19 are formed at positions slightly closer to the inside than both inner sides of the square hole 21.

  Insertion pieces 22 bent at right angles to the front side of the mounting plate 12 are provided at the lower ends of the side portions 12b and 12c. As will be described later, the insertion piece 22 is inserted into a lower slit 27 (see FIGS. 1 to 4) of the building wall plate 24 to position the mounting bracket 11 with respect to the building wall plate 24.
