[Action]

 According to the present invention having the above-described structure, first, the attachment holes for inserting the binding tools are formed in advance at the corresponding positions of the object to be fastened, such as the panel core material, which are arranged adjacent to each other, and these fastening holes are aligned. In this case, the mounting hole should be slightly smaller than the outer diameter of the binding shaft of the binding tool.

Next, the binding head is hit with a tool to forcibly push the binding shaft into the attachment hole of the binding object.

Then, the tooth pattern formed on the contact surface of the binding head bites into the surface of the object to be bound, and at the same time, the projection on the outer periphery of the binding shaft pushes the mounting hole and inserts it into the mounting hole. After that, when the force applied to the binding shaft disappears, the attachment hole for the binding object will be restored to its original state although it is incomplete. As a result, the protrusion of the binding shaft bites into the inner wall surface of the mounting hole to prevent the binding shaft from coming off, and the core members are securely connected and fixed.

Therefore, unlike bolts and nuts, it is not necessary to perform tightening with screws, only tapping with a tool is necessary, there is no troublesome tightening of screws, and there is no time-consuming tightening. Therefore, even if there are many tightening points, the tightening work can be performed easily and in a short time, and the work period can be shortened.

【Example】

 Hereinafter, a preferred embodiment of the present invention will be described in detail with reference to the drawings.

FIG. 1 and FIG. 2 are views showing a connecting structure of a floor panel on the second floor using a binding tool according to an embodiment of the present invention.

In the second floor floor panel connection structure of the present embodiment, the floor panels 30 arranged adjacent to each other are tightly bound together by a binding tool 32.

The floor panel 30 has a frame formed of a wooden core material 34, and a floor material 36 is attached thereon by nailing or nailing. Further, the adjacent core members 34 of the adjacent floor panels 30 are bonded and fixed with an adhesive. Further, the adjacent core members 34 are formed with mounting holes 38 for inserting the binding members 32 at corresponding positions.

The binding device 32 includes a binding head 46 and a binding shaft 48.

The binding head 46 has a disk shape and is adapted to abut the core material 34 on one side. Further, a tooth-shaped portion 52 is formed on a contact surface 50 of the binding head portion 46 with the core material 34 so as to bite into the core material 34 and secure the binding.

The binding shaft 48 connects the core member 34 through the mounting hole 38 formed in the core member 34 of the floor panel 30, and is projected from the central portion of the contact surface 50 of the binding head 46. Are formed integrally. The length of the binding shaft 48 is set to such a length that it can penetrate the core material 34 to be connected, and is set to a diameter having sufficient strength to connect the core material 34. The mounting hole 38 of the core member 34 is formed to have an inner diameter slightly smaller than the outer diameter of the binding shaft 48.

Further, on the outer periphery of the binding shaft 48, a plurality of protrusions 54 capable of biting into the inner wall surface of the mounting hole 38 of the core member 34 are formed along the axial direction. The protrusion 54 is formed as a conical cross section that spreads toward the binding head 46 side.

Next, a floor panel connecting structure using the binding device of this embodiment will be described.

First, the floor panels 30 in which the attachment holes 38 for inserting the bindings 32 are previously formed at corresponding positions of the core member 34 are arranged adjacent to each other, and the core members 34 of the floor panel 30 arranged adjacent to each other are arranged. The mounting holes 38 are aligned with each other and are bonded with an adhesive.

Next, the binding head 46 is hit with a tool such as a hammer 64, the binding shaft 48 of the binding tool 32 is forcibly driven into the mounting hole 38 of the core member 34, and the contact surface 50 of the binding head 46 is pressed. Is brought into contact with one side surface of one core member 34.

Then, the tooth profile 52 formed on the contact surface 50 of the binding head 46 bites into the surface of the core material 34. Then, the protrusion 54 on the outer periphery of the binding shaft 48 pushes the mounting hole 38 and is inserted into the mounting hole 38, and then the mounting hole 38 of the core member 34 is restored to be slightly smaller. The inner wall surface of the hole 38 is bitten to prevent the binding shaft 38 from coming off, and the core members 34 are reliably connected and fixed.

Therefore, unlike bolts and nuts, it is not necessary to perform tightening with screws, and it suffices to simply hit with a tool such as a hammer 64, and there is no troublesome tightening of screws and it takes time to tighten. Absent. Therefore, even if there are many tightening points, the work can be performed easily and in a short time, and the work period can be shortened.

In the present embodiment, in order to prevent the core members 34 from being separated from each other due to the impact of driving the binding tool 32, the driving directions of the binding tool 32 are alternately changed, or the head of the binding tool 32 is driven after driving. It is preferable to strike the core material 34 on the side opposite to the portion 46 to bring the core materials 34 into close contact with each other.

In the above-mentioned embodiment, the binding tool 32 is used for connecting and fixing the floor panel 30 in the panel construction method, but the present invention is not limited to this example, and can be applied to a building such as a conventional construction method and other than the building, and moreover, the floor It is applicable not only to the panel but also to various objects to be fastened.

[Effect of the device]

 As described above, according to the present invention, the binding head of the binding tool is inserted into the attachment hole for inserting the binding tool which is formed in advance at the corresponding position of the fastening object such as the panel core material arranged adjacently. By hitting the part with a tool and driving the binding shaft, the tooth shape part formed on the contact surface of the binding head bites into the surface of the binding target. At the same time, the protrusion on the outer periphery of the binding shaft pushes the mounting hole to insert it into the mounting hole, and when the mounting hole of the object to be fastened becomes smaller due to restoration, the protrusion bites into the inner wall surface of the mounting hole and the binding shaft comes off. Will be prevented. As a result, the cores can be securely connected and fixed to each other. Therefore, unlike the bolts and nuts, it is not necessary to tighten the screws, and it is sufficient to tap them with a tool, and it takes time to tighten them. Even if there are many tightening points, the work can be performed easily and in a short time, and the work period can be shortened.
