Description

[Detailed Description of the Invention] (1) Field of Application in Industry The present invention relates to a nail plate used mainly for tightening joints in the construction of houses, etc., and in particular, the shape and arrangement of the nail part are devised. In particular, it aims to improve workability and bonding strength.

(Also technology) 1. In house construction work, especially in house construction using the frame wall construction method, nail plates are sometimes used to join structural members together.

The nail plate functions as an assembly of joining nails by enlarging each nail portion near the joint at the joint of structural wood or laminated timber phase 11, and is made of stainless steel plate, Shearing a metal plate such as a steel plate at multiple predetermined locations using a press forming machine,
It is configured to be cut and raised by bending, and the cut and raised portion acts as a nail portion.

(Problem to be solved by the invention) However, in the conventional nail plate, sufficient consideration has not been given to the shape of each nail part (cut and raised part) and mutual arrangement, and the nail plate is made of wood etc. When each nail part is bent due to press-fit resistance when press-fitting into a joint part and cannot perform its original function, or if a tensile force etc. is applied to the joint part where the nail plate has been constructed, each nail part that penetrates There was a risk that the nail portion would fall out into the cylinder and the joint portion would be destroyed or damaged.

Furthermore, with conventional nail plates, when each nail part is press-fitted into wood, the fiber direction of the wood is pushed out by a so-called imitation effect based on the wall thickness of the tip part, which has the disadvantage of causing splits at the press-fitting points. Was.

Also, depending on the part where the nail plate is attached, tensile force may act in a direction different from the length direction of the nail plate, but with conventional nail plates, the direction of cutting and raising the plate is entirely Since they are provided in parallel to the ks force direction, there is a problem that the strength is insufficient when a tensile force in a different direction indicated by -j1 is applied.

Furthermore, conventionally, little consideration has been given to the arrangement of each nail portion, resulting in the disadvantage that the density of each nail portion for the same area is low, and the area is not effectively utilized.

(Object of the invention) In view of such conventional problems, the present invention has excellent workability,
It is an object of the present invention to provide a nail plate that is excellent in terms of strength such as tensile force and can be used effectively in terms of area.

(Structure of the Invention) Therefore, in order to achieve the object 1-, in the first invention of the present invention, a plurality of predetermined locations of a metal plate are cut and raised by shearing and bending using a press molding machine, etc. In a nail plate that functions as a joining nail by press-fitting the raised portions into the vicinity of joints between pieces of wood or laminated wood, the tip of the cut-raised portion is narrower than the base end. each cut-and-raised part is set to have at least two different cut-and-raised lengths, and each cut-and-raised part is set to have a first cut-and-raised part arranged in series on a plurality of parallel launches. , second cut-and-raised portions arranged in series in a plurality of parallel columns -L orthogonal to each of the plurality of rows, and a third vJ section arranged at a predetermined angle with each of the rows and columns. It is characterized by consisting of a raised part.

Further, in order to achieve the above object I], in the second aspect of the present invention, each cut-and-raised portion has a distal end narrower than a base end, and each cut-and-raised portion has at least two
The cut-and-raised portions are set to have different cut-and-raised lengths of different types, and each of the cut-and-raised portions includes a first cut-and-raised portion arranged in series in a plurality of parallel rows, and a first cut-and-raised portion arranged in series in a plurality of parallel rows. a second cut-and-raised portion arranged in series on a plurality of orthogonal parallel columns; a third cut-and-raised portion suspended at a predetermined angle from each row and column of No. 111; and the first cut-and-raised portion. Cut and raise part, 2nd! , a fourth cut-and-raised portion disposed in each portion defined by the IJ-raised portion and the third cut-and-raised portion.

(Operations and Effects of the Invention) In the present invention having the above configuration, the cut-and-raised portion is set so as to have at least two different cut-and-raised lengths, so that it is not possible to construct it at the joint of wood, etc. When press-fitting, at the initial stage of press-fitting, first, only the J-raised part with the longest cut-and-raised length is press-fitted, and unlike the conventional example, all the cut-and-raised parts have the same length. Compared to the constructed nail plate, the JL force resistance is much smaller, and press-fitting can be performed more accurately and with less effort.

As the press-fitting progresses further, a second section with a cut-and-raised length that is 1-not longer than the longest cut-and-raised portion is formed. Will the third cut-and-raised rjR begin to be press-fitted, and will the press-fit resistance increase?At this stage, the slenderness ratio of each cut-and-raised portion has become considerably small, so even if a large impact force is applied, each cut-and-raised portion will not seat. There is no fear of giving in, and the moon is certain, power is guaranteed.

Further, in the first invention described in “-”, the stock-out raising part is
19th raised portions arranged in series in a plurality of parallel rows, and a plurality of parallel columns 1- orthogonal to each of the plurality of rows;
and a third cut-and-raised portion arranged at a predetermined angle with respect to each row and each column. The cut-and-raised portions include first cut-and-raised portions arranged in series on a plurality of parallel launches, and second cut-and-raised portions arranged in series on a plurality of parallel columns perpendicular to each of the plurality of rows. , a portion defined by a third cut-and-raised portion arranged at a predetermined angle with each row and each column, and the first FJJ-raised portion, the second cut-and-raised portion, and the third cut-and-raised portion. and a fourth cut-and-raised portion provided at each side of the nail plate, it is possible to resist tensile force in the length direction or width direction of the nail plate, and the length direction or width direction of the nail plate is It can also handle tensile forces in angular directions.

Therefore, the problem of the conventional example in which the strength is extremely reduced depending on the direction of the tensile force is solved, and it can be used with sufficient strength in joints under all conditions.

Further, when adjacent cut-off raised portions of the same type are inserted into a mating crab in the reverse direction, the cut-off raised portions are press-fitted in different directions.

Therefore, there is no conventional drawback that only one side of the joint is easily pulled out due to tensile force with the center of the joint as a boundary, and the performance is significantly improved in terms of strength. 'Order: The degree is increased.

In particular, in the second aspect of the invention, a fourth cut-and-raised portion is provided on the surface Ji'i in a portion defined by the first cut-and-raised portion, the second cut-and-raised portion, and the third cut-and-raised portion H'Xp. Table 1 (6)
