Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a method for fixing wall materials such as prefabricated houses.

(Prior Art) As a structure for fixing a wall material using a conventional fixing method, for example, the one shown in FIG. 10 is known.

In this conventional method of fixing wall materials, the wall material is placed on the wall material fixing surface 102 of an iron frame 101 having a square cross section, and the tapping screws 104 are inserted into the wall material 10.
The wall material 103 and the iron frame 101 are fixed by screwing them onto the iron frame 101 from the surface side of the wall material 3. It was fixed to a stud 106 with a shaped cross section.

(Problems to be Solved by the Invention) However, in such a conventional method of fixing wall materials, the wall material 103 and the iron frame 10
When fixing the screws 1 to 1, the tapping screws 104 were screwed into the wall material 103 from the surface side, which caused problems in that the aesthetic appearance was impaired and it took time and effort to putty the heads of the tapping screws 104.

(Means for Solving the Problems) Therefore, in order to solve the above-mentioned problems, the present invention has a notch at the lower end and drives a protruding pin inserted into the hole in the axial direction. A rivet anchor with an expandable notch is inserted into the bottomed hole of the wall material, which has a bottomed hole that is drilled from the back side and does not penetrate through the front side, through the through hole of the frame or stud. The method for fixing a wall material is characterized in that the wall material is fixed to a frame or a stud by driving the projecting pin.

(Function) Therefore, when fixing a wall material to a frame or stud, parts such as nails, bolts, nuts, etc. can be fixed to the surface side of the wall material without being exposed, and the notch portion can be secured by driving the protruding pin into the wall material. It can be firmly fixed by expanding it.

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

First, the fixing structure of the wall material fixed by the fixing method of the first embodiment will be explained with reference to FIGS. 1 and 2.

Reference numeral 1 denotes an exterior wall surface material made of hard cement.

This outer wall surface material 1 is provided with a plurality of closed-end holes 2 that are opened near the peripheral edge from the back side and do not penetrate through the front side.

Reference numeral 3 denotes a frame for fixing the exterior wall material 1 to the exterior wall material fixing surface 4, and is made of a thin metal plate and has a square cross section. A through hole 5 is provided, and an insertion hole 6 is provided on the surface facing the outer wall surface material fixing surface 4 so as to have the same central axis as the through hole 5.

Reference numeral 7 denotes a rivet anchor, which has a notch 8 at its lower end, and a protruding pin 10 inserted into an axial hole 9.

This rivet anchor 7 is inserted into the bottomed hole 2 of the outer wall material 1 through the through hole 5 of the frame 3, and by driving the protruding pin 10, the notch 8 is expanded and the outer wall material 1 is fixed to the frame 3.

Reference numeral 11 denotes a stud, to which the frame 3 is fixed with a daisy rivet 13 through a resin foam 12. The stud 11 is made of a thin metal plate and has a U-shaped cross section, and has screw nails 14 on its inner surface.
The wooden brick 15 is fixed in place.

Incidentally, this stud 11 is fixed to a ceiling girder 16 and a floor girder 17 as shown in FIG.

Reference numeral 18 denotes a gasket, which is inserted between the adjacent outer wall surface materials 1 and 1 to prevent the infiltration of rain, etc., and is made of rubber.

Reference numeral 19 denotes an inner wall surface material, which is fixed to the wooden bricks 15 via inner wall crosspieces 20 with screw nails 21, and is made of gypsum board.

A heat insulating material 22 is filled between the outer wall surface material 1 and the inner wall surface material 19, and is made of glass wool.

Next, a method for fixing the wall material will be explained with reference to FIGS. 1 to 7.

First, bottomed holes 2 are formed at equal intervals from the back side near the peripheral edge of the outer wall surface material 1 using a drill or the like, and then the bottomed holes 2 are aligned with the through holes 5 of the frame 3, and the bottomed holes 2 are aligned with the through holes 5 of the frame 3. The outer wall material 1 is brought into contact with the outer wall material fixing surface 4 of No. 3.

Next, the rivet anchor 7 is inserted into the frame 3 from the cutout 8 side through the insertion hole 6, and then inserted into the bottomed hole 2 of the outer wall surface material 1 through the through hole 5. Then, by driving in the protruding pin 10, the notch 8 is expanded, and the outer wall surface material 1 is fixed to the frame 3.

Next, screw nails 14 are attached to the inner surface in advance.
The frame 3 is brought into contact with the stud 11 to which the wooden brick 15 is fixed, and the daisy rivet 13 is driven into the frame 3 from the inner surface of the stud 11 to fix the frame 3 to the stud 11.

At this time, the frame 3 is mounted on the studs 1 so that a slight gap is formed between the adjacent exterior wall materials 1, 1.
Fix it to 1.

Next, the inner wall material 19 is fixed to the wooden brick 15 via the inner wall crosspieces 20 with screw nails 21, and the heat insulating material 22 is placed in the gap formed between the outer wall material 1 and the inner wall material 19. Fill.

Next, the stud 11 to which the outer wall surface material 1 and the inner wall surface material 19 are fixed is fixed between the ceiling ridge 16 and the floor ridge 17, and finally, the stud 11 is fixed between the adjacent outer wall surface materials 1, 1. A gasket 18 is inserted into the small gap to prevent rain etc. from entering.

Next, a second embodiment shown in FIGS. 8 and 9 will be described.

In this example, rivet anchor 7 is fixed to stud 1.
This is an example in which the external wall material 1 is directly fixed to the stud 11 by inserting the protruding pin 10 into the bottomed hole 2 of the external wall material 1 through the through hole 23 provided in the stud 1.

Note that the other configurations and operations are the same as those of the first embodiment shown in FIGS. 1 to 7, so the same reference numerals are used in the drawings and explanations thereof will be omitted.

Although the embodiments of the present invention have been described above in detail with reference to the drawings, the specific methods are not limited to these embodiments, and the methods may be changed or added without changing the gist of the present invention. are also included in the present invention.

For example, when fixing the exterior wall surface material to the frame, an adhesive may be used in combination.

(Effects of the Invention) As described above, according to the method for fixing a wall material of the present invention, the wall material can be fixed to a frame or stud without exposing parts such as nails, bolts, nuts, etc. on the surface side of the wall material. It has a beautiful appearance.

Furthermore, since the head of the fixed component is not exposed on the surface of the wall material, there is no need to perform extremely time-consuming work such as putty treatment.

In addition, since it is fixed by driving in a protruding pin and expanding the notch, it can be firmly fixed without complicating the assembly work.
