2. Description of the Related Art Generally, in a prefabricated single-family house or the like, development is underway to make an attic space one living space in order to effectively use the living space. Conventionally, the shed structure of a single-family house has supported the surface materials that constitute the roof by a member for the shed structure such as a bundle and rafters, but such a shed structure requires a large attic space. However, there was a problem that the space behind the hut could not be used effectively.

Therefore, as a means for solving such a problem, the present applicants proposed a roof structure capable of making the most effective use of the attic space (Japanese Patent Application No. 2-158).
No. 936 "Square roof" etc.).

As shown in FIG. 13, this is a first beam member 1a installed along the slope of the roof and a second beam member extending substantially horizontally from the upper end of the first beam member 1a. Bending beam 1 formed by connecting material 1b through gusset plate 1c

According to such a roof-structured structure using the curved beams 1, there is an advantage that the space inside the roof can be wide and the living space can be effectively utilized.

[0006]

By the way, the bending beam 1 used in the above-mentioned roof structure has the following problems to be solved in manufacturing the bent beam 1 in order to butt-bond and fix two square members. ing.

First, when manufacturing a linear beam,
The beam can be formed only by cutting one square bar and finishing the surface, but when manufacturing a bent beam,
It is necessary to cut and process the upper end surface (butting surface) of the first beam member 1a and the abutting surface of the second beam member 1b, which are installed along the slope of the roof, according to a predetermined angle in advance. Particularly, since the angle of the abutting surface of the beam member changes variously depending on the inclination of the roof, it takes a lot of time and labor to process the beam member.

Secondly, in this type of bent beam, since the beam itself supports the roof load, the beam member itself is large, and it is difficult to butt the square members together manually, and the precision of the butt portion is difficult to obtain. It is a point.

The present invention has been proposed in view of the above circumstances. An object of the present invention is to make it possible to easily perform a butt-joining operation between beam members to effectively and appropriately connect beam members forming a bent beam. To provide a simple joining device.

[0010]

In order to achieve the above object, the present invention is directed to a first beam member which is installed along a slope of a roof and extends substantially horizontally from the upper end of the first beam member. A joining device for butt-joining with a second beam member to be projected, wherein a rectangular member to be the first beam member is made to have a longitudinal direction horizontal.
And, and a first table for placing in a state of standing vertically in its cross section, a square timber made of a second beam member, said first
Second mounting table that is mounted in series with the square timber and vertically in the cross-sectional shape thereof, and one end of the second mounting table is vertically moved to make the second mounting table the first mounting table. An inclining means for inclining the second beam material toward the end surface of the first beam material, and a joining means for nailing and joining the first beam material and the second beam material in a state of being butted against each other. It is characterized by consisting of.

[0011]

In the butt-joining operation of the beam members, first, the second beam member is placed on the second mounting table so that the first beam member has its abutting end face facing the abutting end face of the second beam member. Place it on the first mounting table.

When two beam members are set on each of the first and second mounting bases, the tilting means of the second mounting base is operated to raise one end of the second mounting base to raise the second mounting base. The beam member on the mounting table is tilted, the second beam member is dropped toward the first beam member, and the butting operation of the first beam member and the second beam member is performed.

Next, when the joining means is operated to integrate the beam members with each other, a bent beam whose middle part is bent is manufactured.
