2. Description of the Related Art A conventional method for joining inner members is, for example, as shown in FIG. 6 (a), when a wooden frame (14) is fixed to a concrete wall (10), an adhesive is applied to the back side of the wooden frame. A method is used in which (13) is applied and a stick (15) is applied from the front and fixed for 5 to 6 hours to 24 hours.
In such a primitive construction method, the work cannot be performed until the adhesive (13) is dried, and the adhesive (13) alone has a problem in strength, and the nail (12) was struck as a reinforcement. If the nails (12) are used, the surface will be scratched, so there is a problem in appearance, and when high-quality finishing is required, as shown in FIG. 6 (b), the wall (10) and the wooden frame (1) are used.
4) nailing a piece of wood (16) to it, digging a hole (17) on the front side of the wooden frame (14) and nailing it, and after that, the wood (1
The so-called "plug stopper" that embeds 8) and smoothes the surface
The method referred to as is also adopted. However, since this method requires skill, it is difficult to secure a professional technician, the labor cost is high, and the process of repairing with a mortar (19) to make it flush with the wood piece (14) arranged on the back side is required. Join,
As a result, the wall is thicker by the thickness of the mortar, there are many drawbacks such as extra cost and time to dry and it is necessary to interrupt the work, which causes cost increase, and improvement is required. It was Further, as shown in FIG. 6 (c), there was also a construction method in which a wooden brick (20) was put in concrete in advance, and an internal material was nailed to this, but it took a lot of time to formwork. However, there are drawbacks such as poor pouring during concrete driving, rattling of wood that can be thinned, and inability to change the floor plan. The construction method is no longer accepted.

[0003]

Therefore, according to the present invention, the drawbacks of the conventional construction method can be eliminated, and the inner surface material can be fixed on the surface without any damage, and the construction period can be remarkably shortened without requiring a skilled engineer. It was made in order to provide an architectural hardware that can be made and contribute to a significant cost reduction, and an epoch-making construction method using the same. The embodiments of the present invention will be described in detail below.

[Example 1] A stainless steel plate having a plate thickness of 1 to 1.2 mm and a side of 90 mm is used as a substrate (1) on the center lines (2) and (2 ') of the vertical and horizontal directions, in the vicinity of the edges of the respective sides. 9mm considering the thickness of the inner wall material (11) such as wooden frame, pillars, and frame
The arrowhead nails (3) of the front and rear heights are erected, and the arrowhead nails (3))
Adhesive penetration hole (4) is opened close to each side and each side (5)
It is an inner material backing fixing metal fitting in which a centering guide (6) is provided by making a notch in the center and a chamfered screw hole (7) is provided near the center and four corners (each apex). The shape of the adhesive permeation hole (4) is only required to allow the adhesive to permeate and achieve the original purpose, and therefore the shape and the number thereof are arbitrarily set in consideration of the overall design. . Further, the barb (9) of the arrowhead nail (3) is effective even if it has one step, but the effect is more enhanced when it has a two-step and three-step structure.

[0005]

[Embodiment 2] Although Embodiment 1 is a metal fitting used for a large-sized inner material (11) such as a wooden frame or a pillar, this embodiment is a metal fitting used for a narrow inner material (11). It is an example of. A stainless plate having a plate thickness of 1 to 1.2 mm and a side of 30 mm is used as a substrate (1), and recesses (8) are opened at both upper and lower edges on the longitudinal centerline (2), and the deepest part thereof has a depth of about 9 mm. The arrowhead nails (3) with the height of 3 mm are erected, and the adhesive permeation hole (4) is opened at the intersection with the lateral center line (2 '), that is, the central portion, and chamfered screw holes ( 7), which is an inner material back stop fixing metal fitting (B) provided with a centering guide (6) at the intersection of the center line (2 ') and both sides.

[0006]

[Embodiment 3] An explanation will be given of an embodiment of the inner material backing fixing method using the inner material backing fixing metal fittings shown in the first or second embodiment.
When fixing the inner wall material (11) such as pillars and frames, the inner wall material (11) is pre-fixed to the wall (10) with a shape suitable for the direction, width and thickness of the grain of the inner material. Apply the adhesive (13) to the back surface of the metal fitting (A), arrange the cores at 450 mm intervals so as to conform to the legal strength, and use the centering guide (6) to orderly and prevent the nails from protruding. Fix the head with the concrete nails (12) so that the head does not come out on the surface of the substrate (1), apply the internal method material (11) to this from the front side, and consider a batten etc. on the front to protect the surface from damage. Meanwhile, it is fixed by hitting with a hammer or the like.

[0007]

EFFECTS OF THE INVENTION Since the present invention is configured as described above, it is possible to scratch the surface of concrete or other walls (10) with an internal material (11) such as a wooden frame, pillars, or frame. In addition, temporary workers who work part-time can easily and strongly fix it, contributing to cost reduction.

Since a large number of adhesive permeation holes (4) are formed in the substrate (1) and the adhesive is applied to the back surface of the substrate (1), the inner material backing fixing metal fittings (A) or (B) are used. Wall (1
0) can be firmly fixed and the adhesive permeation hole (4)
The adhesive (13) that has permeated the inner surface is adhered to the back side of the inner material (11) and the wall (10), the inner material backing fixing metal fitting (A) or (B), and the inner material (11) Can be firmly fixed together. Further, the adhesive (13) penetrates into the arrowhead nail (3) due to the capillary phenomenon, but if it is applied in advance, it can be more firmly fixed. Since the substrate (1) is provided with the centering guide (6), it is easy to align the dimensions in the vertical and horizontal directions, and the inner backing fixing metal fitting (A) is efficiently arranged so as not to protrude from the inner backing (11). I can work.

Since the tip of the arrowhead nail (3) is formed in the shape of an arrowhead, the inner edge material is gradually restored after being driven into the inner edge material (11), and is caught at the barb (9) portion to be strong. It can be held, and as shown in Fig. 4 (b), the barb (9)
The effect is further doubled when the part of (1) is formed in a plurality of stages, and the adhesive (13) accumulates in the rear part to double the adhesive effect. Therefore, as in the past,
Since work is not interrupted near day and night, work efficiency is improved, which contributes to shortening the construction period and, in the present day, when personnel costs are rising, the cost reduction effect is extremely large.

When the screw hole (7) is chamfered and the board (1) is fixed by using a special concrete nail (12) having a dish-shaped head, the nail head is placed on the board (1). Since the inner wall material (11) can be closely fixed without any gaps, therefore, only the thickness of the substrate (1), which is about 1 mm, protrudes from the surface of the wall (10), so that the interior wall The material (21) can be directly attached to the wall, and the end of the material (21) can be cut up by using a special trowel that is slightly thinner than the thickness of the board (1). The sides of are completely hidden and can be finished neatly.

Further, in the conventional construction method, the adhesive alone has a problem in strength, and since the nail is struck from the front side to reinforce it, there is a defect that the surface is scratched, and when a high-grade finish is required. Employs a method called "plug stopper", but this method requires skill, so it is difficult to secure a professional engineer, the labor cost is high, and the wood piece (17) placed on the back Mortar (2
Since the process of repairing in 1) is added, the wall becomes thicker by the thickness of the mortar, resulting in extra material costs and labor, and the work has to be interrupted until it dries, causing many costs. However, according to the present invention, it is not necessary to adopt this construction method, work efficiency is remarkably improved, and further, an epoch-making construction method having an extremely beautiful finish can be provided, which has many excellent characteristics. .
