Abstract

PURPOSE:To provide a nail which is securely suitable to fix on one kind of soft material on another kind of soft material when a member of soft material where nailing is impossible or difficult is fitted on another member of hard material. CONSTITUTION:One or more structural weak points are provided on a shank 2 with an equal specified space from a nail point 1. The structural weakpoints are referred to as a cutout part 4 eccentrically located from the center of the shank 2, a flattened part which is deformed by pushing pressure, or a central split part of the shank 2.

Description

[Detailed description of the invention]

0001

[Industrial Application Field] The present invention is applicable to interior constructions in which soft materials such as wood, plastic, and plaster that can be nailed are fixed onto hard materials such as metal and concrete that cannot be nailed or are difficult to nail. It relates to nails used to attach decorative materials, anchor materials, etc. to surfaces.

2. Description of the Related Art In building structures, for example, when plasterboard wall materials are attached to light iron base materials as indoor partitions, they are attached using tapping screws. Surrounding edges are attached as decorative materials to the corners of such plasterboard walls and floors, and between walls and ceilings, but the surrounding edges are also attached with adhesive or tapping screws in the same way as above, and in the case of tapping screws, the heads are hidden. , the surface is corrected by filling in the joints. In addition, if the baseboard itself is a partition surface, such as for decorative casing materials, thick tapping screws cannot be used and an adhesive installation method is adopted, but in this case,
The tedious method used was to brace the casing material with tar wood, etc., until the adhesive dried. In addition, it has been extremely difficult to install anchors for shelves and hooks on plasterboard walls, and it has not been strong enough.

0003

Problem to be Solved by the Invention The present invention provides a method for attaching a soft material that can be nailed to a hard material that is difficult or impossible to nail at various locations in a building structure as shown in the above example. If so, it is a nail that is suitable for firmly fixing another soft material on top of that soft material, and it is a nail that can be used as an alternative to the above-mentioned braces such as tarp wood, or it can also be used on soft materials such as plasterboard where the nail does not stop. The aim is to develop anchor nails that provide stable fixation.

0004

[Means for Solving the Problems] The nail of the present invention is provided with one or more strong weak points 3 at a predetermined interval from the nail tip 1, and is provided with means for bending into a curved or hooked shape. . The weak points 3 in terms of strength here refer to the notches 4 cut out from the body 2 and the flattened parts 5 deformed by pressing, etc.
It is preferable that it be formed asymmetrically from the center and only on one side. Furthermore, the slit-shaped middle part 6 that divides the body part 2 into two is also a weak point in the present invention. The number of weak points is arbitrary, and the weak points can be modified in various ways depending on the purpose, such as by providing one or more short notches 4 or by providing a relatively long flat part 5. In addition to general nail types such as ordinary flat head nails and nails with different head and body shapes, elastic material can be used in the body of the nail, such as temporary adhesive or hidden nails that can be used for both temporary and permanent fixing. It can also be used for fixed nails (for example, Japanese Patent Publication No. 63-42124, Japanese Utility Model Publication No. 2-36967), and has an extremely wide range of applications.

[0005]

[Operation] The weak point 3 provided in the body 2 of the nail is that when the nail tip 1 hits the hard material and the nail head is still protruding from the driving surface, if the nail is driven with more force, it will sit in the soft material. Bend and bend. This makes it a strong anchor in the soft material, making it difficult to pull out. In addition, when fixing another soft material on another soft material by adhesive, if you use a nail with elastic material held in place, it will be possible to drive the nail sufficiently until the nail buckles at weak point 3 and the elastic material is compressed. Even if the nail is a base material, the body part 2 of the nail enters without stopping and applies strong pressure to the adhesive surface by deformation of the elastic material. In this case, if a nail with a constriction near the head is used, the head will fly off after gluing, allowing for even stronger installation as a hidden nail with an anchor.

[0006]

[Example] The present invention will be specifically explained below using examples. Figure 1
is the first example, (a) is a side view of the nail, (
b) is a sectional view showing the state after nailing. The nail is tip 1
As a strong weak point 3 on the body part 2 at a predetermined interval from
In this case, three notches 4 are provided. The cutout portion 4 is provided by cutting off the center of the body portion 2 intermittently toward the surface in one direction. As is clear from FIG. 1b, the wall material of the gypsum board 12 is placed on top of the channel steel material 11 called light iron that cannot be penetrated by nails using tapping screws or the adhesive layer 13.
In this state, a baseboard 14 made of wood or plastic material is fixed with an adhesive layer 13, and the nails 10 of the present invention are nailed. The nail tip 1 of the nail 10 slides sideways due to the weak point 3, and is sequentially bent from the notch 4 in the body to form a J-shape. Normally, if you just drive nails into the plasterboard, they will easily come out and the baseboard will not be fixed, but in this case, you may force the baseboard 14.
It is not easy to try to pull out the nail by using it like a lever,
The strong force causes structural failure of the gypsum board 12.

As shown in FIG. 2a, the weak point 3 is formed by deforming one side of the body 2 by pressing to form a flat part 5, but by driving it, it is deformed into a J-shape as shown in FIG. 1b as shown in FIG. 2b. It becomes a strong anchor.

FIG. 3a shows a nail in which a slit-like split 6 is formed in the body 2 as a weak point 3. This nail is attached to a gypsum board 12 attached to a concrete board 15.
It is suitable for nailing baseboards 14, etc., into the concrete board 14, and the nail tip 1 pierces the concrete board 15 to a certain extent and is fixed in position. When the nail is driven further, the intermediate part 6 opens to the left and right, as shown in Figure 3b. It is fixed.

FIG. 4a shows a so-called hold-down/concealed nail in which an elastic material 7 is inserted instead of the normal nail shown in FIG. This is an example of something. In this case as well, Fig. 3
As shown in b, the nail tip 1 pierces the concrete plate 15,
The flat part 5 buckles, and the more it is driven, the more the elastic material 7 deforms and presses, and even if the base is a steel material 11 such as light iron, the baseboard 14 etc. are completely bonded and solidified on the plasterboard 12. hold until After adhesion, by pressing the elastic material 7 horizontally, the constricted part 9
The nail head 8 comes off together with the elastic member 7, and acts as a hidden nail for permanent fixing.

FIG. 5 is a sectional view showing an example of construction of a partition using steel base studs. Light iron channel steel is often used for room partitions in buildings and houses with lightweight steel structures, and in this case, plasterboard is applied directly to the steel 11.
The board 12 is attached to the wall using tapping screws or the like. Gypsum board is also often used for ceiling panels. These gypsum board surfaces are naturally decorated with surrounding edges 14 made of wood or plastic, doorstops, picture frames, and casings 15 that decorate the corners of the ceiling and walls, but eventually However, the supporting force of the gypsum board was weak, and the base could not be fixed sufficiently with light iron or concrete, leading to construction defects such as the adhesive floating and peeling. Figure 4
This problem can be completely prevented by using the nail shown in Figure.

Furthermore, the structure of the present invention can be applied to special nails with hooks on the nail heads, and with these, it is possible to stably support shelves and picture frames that are difficult to attach to plasterboard walls. can. Note that the present invention is not limited to the combination of gypsum board and steel base or concrete base, but can be widely applied to similar combinations of soft materials and hard materials.

[Effects of the Invention] As described in detail above, although the nail of the present invention is a simple structural improvement, its range of application is wide, especially for gypsum board materials, which are the mainstream of fire-resistant structures. As a peg that takes advantage of the effects of a hard base, it is extremely useful in that it not only provides certainty and elegance in the finish, but also helps streamline work.
