A bolt hole is provided on the mounting portion, and a bolt hole through which the fastening bolt is inserted is formed in the bolt locking portion. It is characterized by having a nail hole.

According to a second aspect of the present invention, there is provided a fastening structure for a structural member comprising a member body comprising a member body which is arranged in a row facing each other and an orthogonal member which is orthogonal to each of the member bodies. A fastening bolt is passed through the member main bodies, and one end of the fastening bolt is inserted and locked in a bolt locking portion insertion hole of the metal fitting body attached to the orthogonal member on one side. The other end of the bolt
The fitting body of the fitting main body attached to the orthogonal member on the other side protrudes from the bolt engaging portion insertion hole of the fitting body and is fastened with a nut screwed into this protruding fastening bolt, and the mounting piece of the fitting body uses a bolt and a nail together. It is characterized by being attached.

The present invention according to claim 3 is characterized in that the member main body and the orthogonal member are any of pillars, beams, joists and the like of the building unit.

[0009]

According to the first and second aspects of the present invention, since the mounting piece of the fastener is provided with a mounting hole that can be mounted using both a bolt with a washer and a nail, when a load is applied to the structural member. The initial displacement can be prevented by the nail. Also,
Since the bolt engaging portion of the fastening fitting has an insertion hole through which the fastening bolt is inserted, the fastening of the structural member can be strengthened by inserting the fastening bolt through the insertion hole and bridging it.

According to the third aspect of the present invention, since the structural member is any one of a pillar, a beam, a joist and the like of the building unit, the structural members are tightly fastened to each other to improve the joining strength of the structural member. It is possible to construct a strong unit building by improving the joining strength.

Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is an embodiment of the present invention and is a plan view showing a fastening structure of a floor panel as a structural member. FIG. 2 is an enlarged perspective view showing a portion A of a joint portion of the floor panel of FIG. FIG. 3 is a perspective view of the fastener body. FIG. 4 is an explanatory view showing a method of attaching the fastening fitting.

This embodiment relates to a fastening structure of a fastening member and a structural member using the fastening member. The structural members are the floor joists 11a and 11b of the floor panel 1. The floor panel 1 is a constituent member of a building unit, and a wall panel 2 is erected on an outer edge thereof to form a box-shaped building unit. A plurality of the building units are arranged in parallel with each other,
Adjacent floor panels 1 are joined together to construct a unit building. The fastening fitting is a structural member composed of floor joists 11b, 11b (member body) facing each other and arranged in parallel, and floor joists 11a, 11b (orthogonal members) orthogonal to each of the member bodies. The fastening fittings are floor joists 11b and 11
b (fastening bolt 3) penetrated and bridged between member bodies
3, a nut screwed into the bolt, and a pair of metal fittings 3 attached to each of the orthogonal members. The metal fitting body 3 includes a mounting piece 35 and a bolt locking part 34 vertically provided on the mounting piece 35, and an insertion hole 31 through which the fastening bolt 33 is inserted is formed in the bolt locking part 34. 35 is provided with a bolt hole 32 and a nail hole 51 in which a bolt and a nail 5 can be used in combination. In this embodiment, since the bolts 4 with washers are used as the bolts for fixing the mounting pieces 35, the mounting work can be further accelerated.

In FIG. 4, the bolt 4 with washer is inserted from the floor joist insertion hole when the mounting piece 35 of the metal fitting body 3 is fixed to the floor joist 11 a, and fastened to the mounting piece 35 side with the nut 41. At this time, since the washer 4a is fixed to the bolt 4 with the washer in advance, a wide contact surface with the floor joist 11a is secured, the fixing strength with the floor joist 11a is secured, and the work for mounting the washer is omitted, and the mounting work is omitted. It will be easier. Further, the notch is provided in the floor joist 11a and the washer 4a is embedded, so that there is no protrusion of the bolt head.

In the mounting structure of the structural member of the present embodiment, one end of the fastening bolt 33 is inserted and locked in the insertion hole 31 of the fitting body 3 of the one side floor panel 1, and the other end is the fitting of the other side floor panel 1. The mounting piece of the metal fitting body is attached using a bolt 4 with a washer and a nail 5 in combination with a nut that is projected from the insertion hole 31 of the main body 3 and is screwed into the nut. Therefore, when a load is applied to the structural member, the initial displacement can be prevented by the nail. Further, the floor panels 1 and 1 are tightly fastened by the fastening bolts 33, so that the joining strength of the structural members can be improved.

[0015]

According to the first and second aspects of the present invention, since a mounting hole is provided in the mounting piece of the metal fitting body, the mounting hole can be mounted using both a bolt with a washer and a nail, so that a load is applied to the structural member. The initial displacement can be prevented by the nails.
Further, since the bolt locking portion of the metal fitting body is provided with an insertion hole through which the fastening bolt is inserted, the fastening of the structural member can be strengthened by inserting the fastening bolt through the insertion hole and bridging it.

According to the third aspect of the present invention, since the structural member is any one of a pillar, a beam, a joist and the like of the building unit, the structural members are tightly fastened to each other to improve the joining strength of the structural member. It is possible to construct a strong unit building by improving the joining strength. Therefore, it is suitable as a joint structure of a building.
