Description

DETAILED DESCRIPTION OF THE INVENTION The present invention solves the problem of poor initial adhesive strength when attaching a decorative decorative board such as decorative plywood to a base material using an adhesive, and completely improves the adhesion. This invention relates to a new construction method and staples used therefor.

Printed plywood, veneer plywood, rock wool board, gypsum board, and other decorative decorative boards are used to decorate the interior walls of houses, and the construction is done using the base material (surroundings or fences).
The mainstream method is to use adhesive to fix the material.
Adhesives usually have a low initial adhesive strength and must be kept in a pressed state for a certain period of time after being pasted. For this reason, a common method is to drive a thin nail into the adhesive to temporarily hold it in place, and then pull it out after the adhesive is completed. It is. The temporary nails used in the conventional temporary fixing method used to be temporarily fixed by placing the edge of the veneer on the decorative plywood and driving thin nails from above, but recently, thin nails have been used. Temporary pegs with soft synthetic resin chips in the middle became widely used, and the adhesive work of decorative plywood was dramatically improved. This construction method was filed by the present inventor in 1972 and was patented as Patent No. 870627.

Since then, the technology of temporary nailing has progressed from hand-hammering to machine-hammering, but since the elastic material is relatively large, the nails must be installed in a special way, and most of all, The disadvantage is that the tatsukar currently used cannot be used, and it seems that streamlining the construction method through mechanization has reached its limit.

In view of this situation, the present inventor has discovered that complete initial adhesion can be quickly achieved by mechanical hammering without damaging the surface of decorative plywood, etc., and that there is no or only minimal post-processing after adhesion is completed. As a result of considering a construction method that requires less labor, we decided to eliminate the individual temporary nailing method and adopt the staple method.
After driving the staples, you can either leave them buried in the decorative plywood without removing them, or you can remove the staples with little effort by pinching and pulling the pull piece provided between the staples and the decorative decorative board. I decided to take it.

A detailed explanation will be given below with reference to the drawings.

Staples used for temporarily fixing decorative plywood in the present invention are classified into two basic types, one of which is an immersion type and the other is a pull-out type. 1 and 2 show examples of buried type staples, and FIGS. 3 to 5 show examples of pull-out type staples.

First, a description will be given of a buried staple and a wall adhesion method using it. FIG. 2 is a perspective view showing an example of buried staples, and FIG. 1 is a sectional view of a wall surface using these staples. A to d are examples in which the staples shown in FIG. 2 a to d were driven, respectively. As seen in these figures, when attaching the decorative decorative laminate 3 to the base material 1 via the adhesive layer 2, in the present invention, the adhesive is first attached to the back surface of the base material 1 or the decorative decorative laminate 3. Agent 2 is applied, and then staple 4 is driven in with a tacker. Staple 4
consists of two left and right needle parts 5, 5 and a striking part 6 above them, and a cutting strip is provided on the side or top of the staple 4 so that the needle parts 5, 5 and the striking part 6 are separated when driving is completed. 7 is provided. The staples a and b are provided with a cutting strip 7 on the upper part of the needle part 5 on the side surface thereof, and the examples c and d are provided with two cutting strips 7 on the left and right on the upper part of the staple, that is, the striking part 6. There is. The cut strip here is one that is notched or made thinner so that it is thinner than other parts, and forms a concave strip when a large number of strips are combined. In the examples a to c, the cushioning material 8 is attached to the striking part 6 to prevent the striking part from contacting and damaging the decorative plywood, etc., and to make it easier to remove the striking part 6 if it remains without being separated. It is attached to the bottom of the. Furthermore, staples b and c 4
A highly visible colored display material 9 on the upper surface of the striking part 6
is attached so that when the striking part 6 does not separate, it is noticeable and easy to remove.

A conventionally used tacker (staple driving machine) can be used for the staple having the above structure. For the staples shown in b and c, it is advisable to cut the tip of the hammer plate of the tacker into a square shape. Also, a stapler can be used instead of the stapler. In that case, it is best to remove or rotate the lower base plate of the stapler and apply the staple ejection part directly to the decorative plywood or the like and drive the staple. Both needle parts 5, 5 of the driven staples are buried from the surface of the decorative decorative board and do not appear on the surface. Therefore, even if the initial adhesive strength of the adhesive between the base material and the decorative decorative board is poor, the decorative decorative board is fixed to the wall surface by the needle portions 5 that are driven into the wall. Under such conditions, the adhesive can be stably cured.

Next, the extraction type staple and the construction method using it will be explained. The structure of the pull-out staple is such that a tension piece 10 in the form of a sheet on the inner surface of the staple is provided between the striking part 6 of the staple and the decorative decorative board 3, which can be folded back to the upper part of the staple. Examples are shown in FIGS. 3 to 5. FIGS. 3a and 3b are longitudinal cross-sectional views when driven into a wall surface, respectively. FIG. 4a is a cross-sectional view of FIG. 3a, and FIG. 4b is a cross-sectional view of FIG. 3b. In these figures, the example a is a rectangular tension piece 1, as shown in FIG.
0 was placed on the decorative decorative board when driving the staples, and the staples were driven from above. The example b is an example in which a strip-shaped tension piece 10 is used which is longer than the length of the striking portion 6 of the staple. As shown in FIG. 5, these tension pieces 10 are tape-shaped synthetic resin sheets, cloth, etc. with a certain degree of high tensile strength, and cutting lines 11 are regularly provided thereon.
It is convenient because it can be separated and used each time a staple is driven.

FIG. 6 shows an example of a tucker that can improve efficiency when carrying out the method of the present invention. The figure is a partially cutaway side view. The structure of the main body 12 of this tatsuker is almost the same as that of the conventional one. That is, when the handle 13 is squeezed in the direction of the arrow in the figure, the hammer plate 14, which is supported by a spring, moves against the spring force, and when it reaches a predetermined position, it is released from the locking pawl, and the restored spring force at that time causes the staple 4 to be removed. Type in the . In addition to the conventional structure as described above, the tacker proposed here is equipped with a tension strip magazine 15 on the tacker body so that the staples 4 can be continuously driven from above the tension strips 10. For this purpose, a sector gear 17 is provided on the rotating shaft 16 side of the handle 13, and a large diameter gear 18 is provided in the tension piece magazine 15 so as to mesh with the sector gear 17. The large diameter gear is loosely inserted into the shaft 19 of the tension piece magazine 15. Tension piece magazine 1
A tape-like or flexible wire-like tension piece is wound around the inside of the tension piece 5, and its base is connected to the shaft 19. A small diameter gear 20 is attached to the shaft 19, and a ratchet 21 attached to the large diameter gear 18 meshes with this. With this structure, when the handle 13 is grasped for staple driving, the large diameter gear 18 meshing with the sector gear 17 rotates to continuously provide the tension pieces 10 in the magazine to the staple driving surface. It is. When the handle 13 is released, only the large-diameter gear rotates in the reverse direction, and the small-diameter gear 20 does not rotate in the reverse direction, so that the tension piece does not return into the magazine.

There are various other mechanisms for attaching a magazine to a staple driving machine such as a tacker and sending out a tension piece in order to fix the tension piece by a tacker at the same time as the staple is being driven. Conceivable. For example, one such mechanism is to attach a ratchet directly to the rotating shaft 16 side of the handle 13, attach a gear to the shaft in the center of the magazine, and send out the tension piece by directly rotating the shaft by the ratchet gripping the handle. .

Although the structure of the present invention is clear from the above explanation, its operation and effect are as follows: The present invention replaces the temporary fixing method, which was done by manual work or partially mechanized until the adhesive exerts sufficient adhesive strength, by using a tatker, which has traditionally been used in woodworking, or in some cases. Therefore, it is possible to use a general-purpose tool such as a stapler to perform a temporary fixing method using special staples. Therefore, the work efficiency is greatly improved, the cost is low, and since two needle parts can be driven simultaneously, the driving efficiency is good, and the temporary fixing force is also improved. When the buried staple of the present invention is used, there is no need to remove the staple when adhesion is completed, as is the case with conventional temporary staples. Another advantage is that the needles are buried in the decorative decorative board. On the other hand, the pull-out type staple also has the advantage that it is very easy to pull out due to the tension piece, and the needle hole after being pulled out is small and unnoticeable. Conventionally, staples were simply driven in, and fixation was performed only with staples, but this invention can be said to be useful in that it has expanded the field of use of temporary fixing of adhesives using staples.
