Description

Detailed Description of the Invention a. OBJECT OF THE INVENTION (1) Industrial field of application The present invention uses a so-called double-sided nail having nail portions at both ends thereof for finishing interior materials for construction (door frames, skirting boards, rims, etc.).
To a wall member and a double-sided nail row thereof.

(2) Conventional Technology Conventionally, for example, when installing a decorative plate casing (decorative edge) or the like on a door member of a door frame, a nail or a wood screw is driven through the door frame or casing to drive the wall. A method of fixing to a member is generally adopted.

Therefore, according to this conventional fixing method, the surface of the fixing means such as nails is exposed on the surface of the door frame and the like, and the appearance of the finishing material with a sharp corner is spoiled. In addition, the nail is driven into the door frame or the like to cause a crack. Furthermore, since the nail comes into direct contact with the outside air, corrosion progresses from this portion and damages the finished interior material.

In view of such circumstances, in JP-B-51-10022 or JP-A-50-28122, it is necessary to securely and beautifully fix a finish interior material to a wall material without leaving a nail mark on the surface of the finish interior material. A fixing method that can be used is proposed.

However, since these are single-sided double-sided nails, which are individually handled and driven before use, the fixing work is not performed quickly and is inefficient. Furthermore, the brim formed in the middle of the double-sided nail becomes a great resistance at the time of driving, the penetration to the interior member is not sufficient, and it projects to the member surface and becomes uneven, and adhesion with the door stop contacting the upper surface thereof There is a drawback that it is not done enough.

(3) Problems to be Solved by the Invention The present invention has been made to solve the above-mentioned drawbacks of the prior art, and in the fixing construction of a wood finish interior material using double-sided nails, driving into a wall member. A method for fixing a wood-finished interior material, in which work is performed quickly, and driving into a wall member is performed in a desired state, and as a result, adhesion to an interior material arranged on the upper surface of the wall member is favorably performed, and An object is to provide a double-sided nail row used for a fixing construction method.

B. Configuration of the Invention (1) Means for Solving the Problems In order to achieve the above-mentioned object, the method for fixing and mounting a wood finish interior material with a double-sided nail of the present invention adopts the following configuration (technical means). .

A first aspect of the present invention is a method for fixing and attaching a wood finish interior material, which is an elongated plate-shaped body having an equal thickness, and has upper and lower ends that are sharpened and project in the width direction at an intermediate portion. The double-sided nail 10 is divided into a lower nail portion 12 and an upper nail portion 13 via a collar 11, and the shoulder portion 11a of the collar 11 is formed horizontally and the lower surface 11b is formed into a taper. The side surfaces of 10 are bonded to each other to form a nail row 15, and a striking force is applied to the shoulder portion 11a of the collar 11 of the double-sided nail 10 at the end of the nail row 15 to cause the double-sided nail 10 to be separated from the other double-sided nail 10. These double-sided nails 10 are continuously driven into the wall material 40 at a predetermined interval until the lower nail portion 12 and the flange 11a are buried in the surface of the wall material 40 after being peeled off, and then the finish interior material 41 Is positioned above the driven double-sided nail 10, and then, the finish interior material 41 is crimped with a striking tree 42. It is characterized in that it is driven into the upper nail portion 13 of the double-sided nail 10 by applying force.

A second invention is a nail row used for carrying out the first invention, which is an elongated plate-shaped body having a uniform thickness, in which the upper and lower ends are sharpened, and in the middle part It is divided into a lower nail portion 12 and an upper nail portion 13 through a collar 11 projecting in the width direction, and a shoulder portion 11a of the collar 11 is horizontally formed and a lower surface 11b is tapered. The nail 10 is characterized in that the side surfaces of the double-sided nail 10 are bonded to each other.

(2) Action When driving the double-sided nail 10, the main body of the nail is slender and penetrates into the wall member with a small impact force.
Then, the impact force is absorbed by the tapered surface 11a of the collar 11, and the collar 11 is not left untouched on the surface of the wall member,
Buried in the desired state.

(3) Example An example of a method of fixing a wood finish interior material with a double-sided nail and a double-sided nail row of the present invention will be described with reference to the drawings.

1 and 2 show an embodiment of a double-sided nail and a row of nails used for practicing the present invention.

As shown in FIG. 1, the double-sided nail 10 has an elongated plate shape with an equal thickness, and the upper and lower ends are sharpened to form a nail portion,
A collar 11 is stretched in the width direction in the middle portion, and is divided into a lower nail portion 12 and an upper nail portion 13 via the collar 11. The lower nail part
12 is longer than the upper nail portion 13. A shoulder 11a of the collar 11 is formed horizontally, and a lower surface 11b is formed tapered. The collar 11 serves as a surface for receiving a striking force and also serves as a resistance portion for driving, and further exhibits a multi-function such as a holding function in the nail driving machine. Saw teeth 13a are formed on both sides of the upper nail portion 13, but they can be omitted as appropriate. The double-sided nail 10 may be made of metal (usually steel) or hard synthetic resin.

The present double-sided nail 10 is particularly applied to a nailing machine that drives nails continuously.

For this reason, the double-sided nails 10 are adhered to each other with an adhesive that easily peels from each other to form the nail row 15 shown in FIG.

The nailing machine may be manual or motive power, and may be mechanical (mainly compressed air is used) or electric (mainly solenoid).

3 to 5 show one row of the mechanism of the nailing machine using the above-mentioned nail row 15.

FIG. 3 is a partial cross-sectional view showing the whole, and FIGS. 4 and 5 are cross-sectional views of a main part thereof.

In the figure, 20 is an electric nailer, and a drive unit 20
A, a handle portion 20B, and a nail row accommodating portion 20C.

In the drive unit 20A, reference numeral 21 is a plunger having a bit portion 22 below, and is driven up and down by excitation / non-excitation of a solenoid 23. At the lower end of the plunger 21, a bit portion 22 specially devised for hitting the double-sided nail 10 is integrally fixed. A coil spring 24 returns the plunger 21 to its original position.

In the handle portion 20B, 26 is a handle and 27 is a trigger.

The above mechanism is publicly known except the bit portion 22 at the lower end of the plunger 21, and the detailed description thereof will be omitted.

An accommodation space 30 for accommodating the nail row 15 is formed in the nail row accommodation section 20C. Guide members 31 are provided on both sides of the accommodation space 30 so as to project in the longitudinal direction, and the collar 11 of the double-sided nail 10 is provided on the guide member 31.
Place and guide the nail row 15. The nail row 15 is constantly pushed forward by a biasing force of a spring (not shown) or the like from the rear.

Further, a suitable number of spacers 32 are provided on the front wall surface of the accommodation space 30, and the double-sided nails 10 at the tips of the nail rows 15 are connected to the plunger 21.
It is positioned just below the striking position.

33 is an exit of a nail.

The bit portion 22 is formed in a bifurcated shape, straddles the upper nail portion 13 of the double-sided nail 10, and is arranged with its lower end surface 22a slightly separated from the upper surface of the shoulder portion 11a of the collar 11 of the double-sided nail 10.

The operation of the nail driver 20 is as follows.

When the trigger 27 is pulled, the solenoid 23 is driven, and the magnetic excitation force pushes down the plunger 21 at a rapid speed. With the downward movement of the plunger 21, the bit portion 22 at the lower end of the plunger 21
Collides with the shoulder 11a of the collar 11 of the double-sided nail 10 at the head of the nail row 15,
The double-sided nail 10 is pushed downward, and the nails 10 pop out from the injection port 33.

When the plunger 21 moves downward, the solenoid 23 is immediately deenergized, and the plunger 21 returns to its original position by the biasing force of the coil spring 24. Further, since the nail row 15 receives the biasing force from the rear side, it is sent to the front side and collides with the spacer 32 to stop at a predetermined position.

Using the above-mentioned double-sided nail 10 and the nailing machine 20, the method for fixing the wood finish interior material of this embodiment is carried out as follows.

In this embodiment, an example of application to a fixed construction of a door frame attached around the opening of the wall is shown.

(1) This double-sided nail is attached to the wall member 40 at the mounting position of the door frame door stop.
The 10 is driven using the nail driver 20 over the required distance (see FIG. 6).

When the double-sided nail 10 is driven, a striking force is applied to the flange 11 and the double-sided nail 10 is driven until the flange 11 is embedded in the surface of the wall member 40. At this time, since the lower nail portion 12 of the double-sided nail 10 is slender, it plunges into the wall member 40 by a sudden impact force, but the impact force is absorbed by the taper surface 11b of the collar 11, and the collar 11 is a wall member. 40
There is no unpunched part of the collar 11 protruding to the surface of the, and it is driven in in a good state.

In addition, since the double-sided nail 10 is configured in the nail row 15 and accommodated in the nail driving machine 20, continuous hammering is possible and a quick hammering operation is performed.

(2) The door stop 41 is positioned corresponding to the already driven double-sided nail 10, and the striking tree 42 is brought into contact with the surface of the door stop 41,
The door stop 41 is driven into the double-sided nail 10 by applying a striking force with a mallet or the like through the striking tree 42 (see FIG. 7).

In this case, an adhesive is appropriately applied to the back surface of the door stop 41 of the door frame. With the solidification of this adhesive, the door stop 41 is the wall member 40.
Is firmly fixed to.

When the upper nail portion 13 of the double-sided nail 10 has saw teeth 13a, the fixing force between the door stop 41 and the nail further increases, and the door stop 41 is more firmly fixed to the wall member 40. Therefore, the distance between the double-sided nails 10 can be increased, and the required number can be reduced.

C. EFFECTS OF THE INVENTION Since the present invention has the above-described structure and exerts operations, it has the following unique effects.

According to the method of fixing and attaching the wood finish interior material of the present invention, continuous driving is possible by using the nail row, and the driving operation can be speeded up.

The double-sided nails that make up the row of nails have a slender body,
It can easily penetrate into the wall member with a small impact force. Moreover, the impact force is appropriately absorbed by the taper surface of the collar, and there is no residual impact of the collar that the collar projects onto the surface of the wall member, and it is driven in a good state.

Since there is no unpunched collar, an interior member such as a door stop that is brought into contact with the surface of the wall member via an adhesive is favorably fixed.

Since the double-sided nails forming the double-sided nail row are simple in shape, the double-sided nails can be easily processed, the manufacturing cost is low, and a large amount can be manufactured. Also, the double-sided nail row can be easily obtained by bonding the double-sided nails.
