Description

[Detailed Description of the Invention] [Industrial Field of Application] The present invention relates to a mounting structure suitable for horizontally extending hard wall materials. [Prior art] In general, many building materials have a dowel structure on their longitudinal side edges, and hard wall materials in particular are attached with metal fittings, or by drilling mounting holes into the wall material. Attachment holes were drilled during manufacturing, and nails were driven into these holes to attach the device to the frame. However, when using metal fittings, the structure is simply held down, and when drilling the mounting holes on site with a drill, the hard wall material is often broken or damaged, which is inefficient. It was hot. In addition, the hard wall material with mounting holes drilled during manufacturing had a thin wall thickness at the part where the nails were to be driven, and was made of brittle material, so it was easy to accidentally damage the hard wall material when nailing was done with a hammer. It was a lot. For this reason, driving nails required skill. [Purpose of the invention] The present invention eliminates these drawbacks, and in addition to using a drop-in type for hard wall material construction, the male part is fixed by using the wall material pressing part, fitting bending part, and locking part. By holding the wall material in surface contact with the two, and inserting the insertion bending part into the fitting groove of the female part and the insertion protrusion of the male part, the wall material can be attached to the frame highly efficiently and reliably. To provide a mounting structure for a hard wall material that can be extremely easily constructed without requiring any skill, and can form a highly waterproof wall. [Structure of the invention] An embodiment of the mounting structure for a hard wall material according to the invention will be described in detail below with reference to the drawings. 1st
The figure is a perspective view showing a typical example of a hard wall material (hereinafter simply referred to as wall material) A used in the present invention.
To explain further, wall material A is cement board, ceramic board,
It is made of one type of plate, such as a porcelain plate, a calcium silicate plate, or a calcium carbonate plate, and has a male part 2 on one side edge in the longitudinal direction of the decorative surface 1 and a female part 6 on the other side edge. In particular, the male part 2 includes an insert protrusion 3 that projects outward from the edge of the decorative surface 1 ;
It is formed from an engagement groove 4 having a U-shaped cross section as an upper edge, and an extension portion 5 extending the lower part of the engagement groove 4 outward. Further, the female part 6 is formed from a fitting groove 7 formed inwardly in a U-shape and a notch 9 provided on the back surface of the lower part 8 of the fitting groove 7.
To explain further, the insertion protrusion 3 is in the fitting groove 7,
The lower part 8 is fitted into the engagement groove 4, and the connection structure of the wall material A is doubled to improve waterproofness and engagement force. That is, the distance from the edge of the decorative surface 1 to the tip of the insertion protrusion 3 is l ₁ , the distance from the innermost part of the engagement groove 4 to the tip of the insertion protrusion 3 is l ₂ , and the distance of the engagement groove 4 is l 1 . The distance from the innermost part to the edge of the extension part 5 is l ₃ , the distance from the edge of the decorative surface 1 to the innermost part of the fitting groove 7 is l ₄ , and the distance from the innermost part of the fitting groove 7 to the tip of the lower part 8 The distance from _the side of the notch 9 to the tip of the lower part 8 is
L ₆ , the height of the end of the extension part 5 is h ₁ , and the height of the side surface of the notch part 9 is h ₂ , then l ₁ ≦l ₄ , l ₂ ≒l ₅ , l ₃ ≦l ₆ ,
The wall material A has the relationship h ₁ ≦h ₂ . As shown in a perspective view of a typical example in FIG. 2, the mounting bracket B includes a fixing part 10, a rising part 11 that bends the edge of the fixing part 10 upward, and a tip of the rising part 11 that is approximately horizontal. A wall material pressing part 12 bent in a shape, a fitting bent part 13 in which the tip of the wall material pressing part 12 is bent into a U-shape, and an insertion bending part in which the end edge of the fitting bending part 13 is bent in a U-shape. 14, and a locking portion 15 extending outward from the end edge of the insertion bent portion 14. To explain further, the mounting bracket B is a drop-in type for wall material A to be installed from the foundation to the ridge, and in order to make full use of its elasticity and strength, and to reduce costs. It is formed from two metal plates using a press, roll forming machine, etc. As shown in FIGS. 3a and 3b, this mounting bracket B is for fixing the wall material A to a main frame α, such as a main pillar or a stud, via a nail β. In addition, a plurality of mounting holes 10a are formed in the fixed part 10 according to the thickness of the metal plate, and an auxiliary locking tongue 10b is formed at the end for reinforcing locking and for preventing danger. It is preferable. Further, the rising portion 11 is bent, for example, at right angles to the fixed portion 10, and its height _h3 is approximately equal to the height _h1 of the edge of the extension portion 5 of the wall material A. The wall material pressing portion 12 is a portion that fixes the extension portion 5 of the wall material A to the frame α by the elasticity of the mounting bracket B itself, and its range l ₇ is approximately the same length as the aforementioned l ₃ . Further, the fitting bending portion 13 applies a spring back to the wall material pressing portion 12, and engages with the engagement groove 4 of the wall material A, and also engages the lower part 8 of the upper wall material A. It is something. The insertion bending part 14 is a part that holds the insertion protrusion 3 of the male part 2 of the wall material A, and is inserted into the fitting groove 7 of the female part 6 and fixed. Locking part 15
is a part that fixes the lower wall material A and serves as a guide when inserting the upper wall material A.
In particular, the locking piece 1 provided by bending the tip of the locking portion 15
6, when a step is provided between the insertion protrusion 3 and the decorative surface 1 , the step portion is hooked and locked. Here, the distance l ₈ from the fitting bent portion 13 to the insertion bent portion 14 is approximately equal to the aforementioned l ₂ , and the length l ₉ of the locking portion 15 is approximately equal to the aforementioned l ₁ . [Example of construction] Next, an example of construction will be explained. Now, it is assumed that the wall material A shown in FIG. 1 is fixed to the building frame α as shown in FIGS. 3a and 3b using the mounting brackets B shown in FIG. 2. Therefore, as shown in Figure 3a, the main pillar,
The frame consisting of studs, waterproof sheets, etc. (the waterproof sheets are omitted in the figure) α is connected to the nth stage wall material A. The fitting bent portion ₁ of the mounting bracket B is connected to the engaging groove 4 of the male part 2 of 1.
At the same time, insert the insertion protrusion 3 at the locking part 15.
The fixing part 10 is driven into the frame body α using nails β such that the extension part 5 is locked and the wall material pressing part 12 is pressed against the extension part 5. At this time, the nail β is not driven directly into the wall material A ₁ , but at a distance from the wall material A ₁ , so when driving the nail, the nail β is not driven directly into the wall material A 1.
_A1 will not be damaged or destroyed. Next, Figure 3b
As shown in , the female part 6 of the wall material A ₂ of the
The fitting groove 7 is guided by the locking part 15, and it is dropped into the insertion protrusion 3 of the wall material _A1 and the insertion bent part 14 of the mounting bracket B. At this time, the n-th stage wall material A ₁ is pressed against the frame α by the elasticity of the mounting bracket B, and is also pressed against the framework α by the own weight of the n+1-th stage wall material A ₂ . Therefore, it is securely fixed to the frame α. Furthermore, since the mounting bracket B is hidden behind the wall material _A2 and is not exposed on the surface, and the nail heads are not exposed, it is possible to form a framework that is highly waterproof and aesthetically pleasing. By repeating these steps sequentially from the foundation to the ridge, the wall can be formed. Furthermore, when forming the wall through the above steps, caulking material 17 may be planted in at least one of the positions indicated by hatching, or the surface of the wall may be spray-painted. [Other Examples] The wall material A and the mounting bracket B described above are only one example of the members of the mounting structure for a hard wall material according to the present invention, and are shown in FIGS. 4a-q and 5a- k, Figure 6a
