[0001]

TECHNICAL FIELD The present invention relates to a beam connecting structure, a steel beam with a beam connecting fitting, and a beam connecting method.

[0002]

[Background Art and Problems to be Solved by the Invention] In a building structure such as a hipped roof, a half-gable roof, or a roof with a gabled roof, when the frame of the building structure is constructed by roof supporting beams, the beams are connected to each other. The connecting structure of (3) occurs in areas such as A, B, and C of the building structure 100 shown in FIG. In the figure, 102 is a beam and 104 is a bent beam, which are connected to each other. For details of this connection structure, see FIG.
It has a structure as shown in FIG.

That is, FIG. 9 (A) shows a wooden beam.
As shown in FIG. 3, a wooden plate 132 is provided on one side surface of the wooden connection target object 130, and the wooden beam 140 faces the plate 132.
Is attached with the metal fitting 120 interposed. At that time, metal fitting 1
20, the mounting portion 122 is attached to the plate 132 side, and the beam receiving portion 124 is attached to the wooden beam 140 side with nails 136.

In the case of the steel beam, as shown in FIG. 9B, a wooden plate 134 is provided on one side of the wooden connecting object 130.
And the steel beam 160 is attached to face the plate 134 with a pair of metal fittings 150a and 150b interposed. At this time, the pair of metal fittings 150a and 150b are attached to the mounting portion 152a.
152b is attached to the plate 134 side with a nail or the like, the beam receiving portions 154a and 154b are attached to the steel beam 160 side, and the steel beam 16
Hole 162 drilled in 0 and a pair of metal fittings 150a, 150
It is attached by screwing holes 156a and 156b formed in b with screws and nuts.

By the way, as a beam for supporting a roof provided in a wooden building, a wooden beam using a peeling material has been usually used. In recent years, however, the price of timber has been soaring and the environment has been deteriorated due to a decrease in wood resources which can be used as a building material. Due to problems, it is becoming difficult to obtain timber, and it is becoming difficult to stably supply materials. In particular, since the roof supporting beam is a large member, when it is a wooden beam made of peeling material, its weight is considerably heavy, and it is desired to reduce its weight.

In view of this point, a metal steel beam, which can be stably obtained and can be reduced in weight, has been used in place of a wooden beam as a roof supporting beam.

When the above steel beams are connected to some object to be connected, for example, when constructing a shed structure, both ends of the roof support beam are attached to the outer wall body or inner wall body of the building, and the ends thereof are connected with metal fittings. In the case of attaching to a roofing panel or the like that is a roof support, since the object to be connected is wood, it can be connected using a conventional metal fitting as shown in FIG. 9 (B).

On the contrary, when the object to be connected is a steel member, particularly a steel beam, it is difficult to connect the conventional metal fittings as they are.

Further, since the work of hoisting with a crane or the like to attach the roof supporting beam to the building is a work performed at a high place for the roof supporting beam which is a large member, simplification of the work is desired. In particular, the metal fittings are fixed to the objects to be connected by nailing at the construction site, so that there is a problem that the connecting work is troublesome.

Therefore, an object of the present invention is to provide a beam connecting structure and a steel beam with a beam connecting metal fitting which can stably supply a lightweight beam member and can save the labor of beam connecting work on site. Another object is to provide a beam connecting method.
