BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a connection structure between an eaves front beam and an under eaves beam which constitutes an overhang structure when forming an overhang structure at the eaves end of a building.

[0002]

2. Description of the Related Art Conventionally, it has been desired to effectively use a space under an eave formed below a roof protruding toward the eaves side of a building body. It is common practice to form an overhanging structure on the floor and to widen the indoor space of the building by this overhanging structure. When forming a projecting structure, a diagonal beam under the eaves is projected toward the eaves from the roof beam supporting the eaves of the roof, and the tip of the diagonal eaves under the eaves is received by the pillars. The eaves front beam is connected to the connecting tool, and the eaves front beam is installed between the adjacent eaves diagonal beams to form a frame structure.

[0003]

However, in the conventional example as described above, it is necessary to erect a pillar on the tip side of each diagonal beam under the eaves when forming the frame structure forming the projecting structure. , Without the pillar, it is impossible to connect the diagonal beam under the eaves and the front beam under the eaves to form a frame structure, and there is a problem that the construction man-hour increases due to the construction of the pillar,
In particular, when a frame structure is added, it is necessary to erect a pillar at a predetermined position each time, and there is a problem that the use of the pillar increases the cost and increases the number of construction steps.

The present invention is intended to solve the above-mentioned problems, and it is possible to form a frame structure by joining an oblique beam under the eaves and a front beam under the eaves without installing a column. It is intended to be able to easily add more.

[0005]

According to the present invention, in order to achieve the above object, a diagonal beam 2 under the eaves is provided obliquely downward from the roof beam 1 supporting the eaves portion of the roof of the building toward the eaves.
The eaves front beam 3 is erected so as to be orthogonal to the eaves diagonal beam 2 between the eaves diagonal beams 2 adjacent to each other at the end of the eaves diagonal beam 2, and the frame structure of the overhanging structure 6 is formed between the eaves diagonal beam 2 and the eaves front beam 3. A connecting plate 30 that constitutes the body 6'and has a through hole 30a at one end and a through hole 30b at the other end is provided at the tip of the eaves-down diagonal beam 2 and one side of the connecting plate 30 is provided. Projected from the end of the eaves lower front beam 3 in the through hole 30a located in half
The fixing piece 31 is connected and fixed by the fixing tool 7.

[0006]

The eaves front beam 3 can be connected to the eaves diagonal beam 2 by using the through holes 30a provided in the half of the connecting plate 30 on one side.
The frame structure 6'can be formed by joining the under-front beam 3 with the eaves. In addition, in the case of adding a frame structure 6 ', among the through holes 30a and 30b provided on both sides of the connecting plate 30, the through hole 30b located in the other half of the one side is used to attach the front eaves beam 3 under the eaves. It can be connected to the under eaves diagonal beam 2, and the under eaves diagonal beam 2 and the eaves under front beam 3 can be joined to each other without adding another member to easily add the frame structure 6 '. it can.
