ある。2. Description of the Related Art Bolts are manufactured by processing a linear steel material, and the head is formed by cold or hot forging means. The head diameter is restricted by the steel diameter because the round bar-shaped steel is pressed and formed by pressing.If the head diameter deviates from the allowable range according to the steel diameter, the original function of the bolt will be reduced and it will be easier. And has a problem in durability. That is, if the diameter of the head is increased in order to enhance the pull-out resistance, the original function of the bolt is reduced, and the bolt is easily broken, resulting in a problem in durability.

作が確実に行われる。[0007] In the frame assembly device according to the embodiment, a joint p is formed by a bolt A according to the present invention and a nut n screwed to the pillar p.
Is fixed and protruded from the side surface of the column p, the joining metal member a is engaged with the slit c formed at the end of the horizontal member S, and the horizontal member S and the connecting metal member a are engaged with the locking bolt b and the drift pin. d, and the bolt A of the present invention is provided with
When the nut is screwed and fixed to the column p, the bolt main body 1 for screwing the nut n into the column p is pressed by the fitting of the locking claw 11 into the column p (insertion). Is not so large when screwed into the screw, so that the nut n is fixed without moving and the nut n is smoothly assembled. The claw 11 is inserted into the column p, and the square root 8 of the bolt main body 1 matches the square mounting hole 5 of the washer 2 so that the root 8 is fixed to the mounting hole 5.
Since the rotation inside is restricted, the above-mentioned tightening operation is performed reliably.

A circular flat head 6 and a threaded rod 7 having the screw at the tip
And the base 8 is interposed therebetween.
The head 6 of the bolt main body 1 has a flat bulge at the center of its upper surface (when the head 6 is on the upper side and the threaded rod 7 is on the lower side) and overlaps the entire base 8. 6a is provided on the lower surface of the head 6 due to the presence of the bulging portion 6a.
Even if a tensile force is applied when tightening the nut n, the lower surface of the head is reinforced to prevent breakage (breakage) from the portion.

る。In the embodiment, the base 8 is made to conform to the square shape of the mounting hole 5 provided in the washer material 2.
If the mounting hole 5 has a non-circular shape, the shape of the mounting hole 5 only needs to match the shape of the mounting hole 5. In short, the nut n is screwed into the threaded rod portion 7. At this time, any shape may be used as long as a part of the outer peripheral edge of the base 8 is pressed against the edge of the mounting hole 5 to prevent the nut 8 from rotating together.

機能させるようにしてある。The washer member 2 is formed of a circular flat body (a square shape is also possible), and the mounting hole 5 (a circular concave portion for partially engaging the head 6 on one side is provided at the center). This need not be provided), and a tightened body (a column p in the embodiment) is provided at the peripheral end.
The engaging claws 11, 11, 11, which fit into (pierce)
11 is provided, the threaded rod 7 is passed through the mounting hole 5 of the washer 2, and the base 8 is engaged with the mounting hole 5 to combine the bolt main body 1 and the washer 2. The assembled state is maintained by clamping the washer 2 with the clamping ring 3 and the head 6 assembled with the screw section 7 so as to penetrate the screw section 7, and the assembled state is defined as a bolt. It works.

連設して構成してある。The holding ring 3 has a plurality of elastic locking pieces 10, 10, 10, 10 on the circumference of a ring-shaped (circular) main piece 9.
The elastic locking portion 10 is formed by projecting the elastic locking portion 10 from the base end (a portion connected to the main body piece 9) to the distal end.
And is protruded as described above in an inclined shape gradually approaching the tip end. That is, the elastic locking piece 10 is formed so as to protrude obliquely toward one surface (a lower surface corresponding to the upper surface) of the main body piece 9 on the tip end side of the screw portion 7 (to form a tapered shape as a whole). It is constructed in series.

Are resiliently deformed and spread apart from each other. In this state, the clamping ring 3 is moved to a position where the clamping ring 3 comes into contact with the washer 2 by moving the washer 2 relatively to the head 6.
Thus, the bolt A of the embodiment is obtained.

かつ、取扱い上の至便さを果すことができる。The holding ring 3 has a threaded rod portion 7 at its inner peripheral edge.
In the state where the bolts are pressed against the main body, the holding state of the bolt main body 1 and the washer material 2 by the holding ring 3 is maintained, and loss of the member as a bolt due to a state where each part is separated is prevented.
In addition, convenience in handling can be achieved.

きる。The present invention has the configuration described above,
By applying the bolt as a tightening bolt for a body to be tightened such as wood into which the locking claw is inserted (inserted), it is possible to provide a bolt suitable for tightening operation that does not rotate together with the nut and maintain a fixed position when tightening the nut. Suitable for bolts which are assembled with the nut and therefore the nut must be assembled in a narrow space, and have a head with a relatively large diameter corresponding to the threaded portion, and therefore a tensile load In response to this, it is possible to provide a bolt that does not easily sink into a tightened body (such as wood).
