Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a joining structure of building components in an industrialized building, and can be used for joining a base material of a roof panel or a wall panel, particularly a deformed panel such as a triangle or a trapezoid.

[0002]

2. Description of the Related Art As a roof panel arranged on the roof of a building such as a house, a deformed panel such as a triangle or a trapezoid is used in addition to a fixed panel (quadrangle). Of these, for example, FIG.
The triangular roof panel 1 shown in FIG. 2 is constructed by attaching a roof material (not shown) to a panel frame 2 having a substantially triangular shape in a plane. Conventionally, when manufacturing the above-mentioned panel frame 2, the joining ends 4 of the two base materials 3 are obliquely cut corresponding to the respective joining angles, and the base material 5 not subjected to the oblique cutting process is formed. Were combined in a triangular shape, and their joint ends were joined by welding 6. Alternatively, as shown in FIG. 8, a base material 7 whose joint end 4 is not obliquely processed is used, and the joint member 8 is arranged between the joint ends 4 of the base material 7, and the joint member 8 is joined. The member 8 and both base materials 7 were joined by welding 6.

[0003]

However, as described above, it is difficult to obtain precision in the processing of cutting the joining end portion 4 of the base material 3 obliquely according to the joining angle, the quality is not stable, and the base material 3 is not stable. It took a lot of time and labor to process the end part of the and the cost was high.
Further, since it is necessary to prepare the roof panels 1 having various shapes and sizes, the joining angles of the base materials 3 are also various.
Therefore, there is a problem in that it is necessary to prepare a large number of types of base materials 3 having different cutting angles of the joint ends 4, and the cost of parts is also increased. Furthermore, when the joining member 8 is used for joining the two base materials 7, it is difficult to hold the two base materials 7 at a predetermined joining angle with the corners of the two joining ends 4 abutting each other. Is. Moreover, there has been a problem that the quality of the six welded portions is not stable because the length of the joint between the base material 7 and the joint member 8 changes with the change in the joint angle between the base materials 7. Further, since the joining member 8 itself is a small item, it is difficult to handle. For example, it is difficult to hold the base materials 7 so as to straddle them during the joining operation.

The object of the present invention is to join the building components at an oblique angle without the need for oblique cutting of the joint ends of the building components, and to make the members common and to construct the building components. It is an object of the present invention to provide a joint structure of building components in an industrialized building, which can join the concrete to a predetermined angle with high accuracy and stable quality.

[0006]

In the construction of the present invention, in order to join two building components at a predetermined joining angle via a joining member, both building components are made of a channel material having a hollow portion.
Because it is, between the ends of the two building elements, and building
A joining member is arranged in the hollow portion of the building component, and the ends of the two building components are abutted so as to sandwich the protrusion of the joining member. Then, the two building components are rocked with the projection as a fulcrum to set the joining angle, and the joining portions of the respective building components and the joining member are joined. In this way, since the projecting portion that serves as a reference for joining the both ends is provided in the joining member, no positional deviation occurs during joining, and the two building components can be joined accurately. Moreover, unlike the conventional case, it is not necessary to obliquely process the joining end portion of the base material according to the joining angle. In addition, the joint surface of this joint member is

Further, when the protrusion of the joining member is formed by cutting and raising, the interval between the ends of the building component sandwiching the protrusion of the joining member is the thickness of the protrusion, and the building components are relatively Joined at close positions. Therefore, when the building component forms, for example, a triangular roof panel frame, and the roofing material is attached to the roof panel frame to form the roof panel, the building component can be arranged close to the apex of the roof panel. Therefore, the roof material can be supported at a position close to the apex of the roof panel, so that there is an advantage that the strength is improved. Further, if it is formed by drawing, the number of processing steps can be reduced and the cost of the member can be reduced. Further, when the angle scale is provided along the arc of the joint surface material of the joint member, the joint angle formed by both building components can be easily set.

As shown in FIG. 3, the joining member 10 has a pair of joining surface portions 11 formed in a substantially semicircular shape having an arc R having a predetermined radius L, and the straight sides of the joining surface portions 11. The bottom surface portion 12 that is connected to the joining surface portion 11 so as to be orthogonal to
And a projecting piece 13 as a projecting portion formed by cutting and raising the bottom surface portion 12. This protrusion 1
3 is formed by bending the base end 13A that is cut and raised in a direction perpendicular to the bottom surface portion 12 and on the side opposite to the joint surface portion 11. The base end 13A is aligned with the center line C so as to pass through the center of the arc R and be orthogonal to the joint surface portion 11. Further, the radius L of the joint surface portion 11 is a width dimension orthogonal to the longitudinal direction of the base material 7 (internal dimension M of the flange end portion 7D).
The size is set shorter than 1). Further, the width dimension of the bottom surface portion 12 orthogonal to the joining surface portion 11 is determined by the web end portion 7.
It is set to a dimension shorter than the inner dimension M2 of E. In this way, the joining member 10 has a size that can be arranged in the hollow portion 7C of the base material 7. An angle scale 14 is provided on the outer side surface of the joining surface portion 11 along the arc R in the radial direction.

The joining member 10 constructed as described above is arranged so as to straddle the hollow portion 7C of the two base materials 7 arranged opposite to each other, and is bent vertically from the bottom portion 12 of the joining member 10.

Further, the shape of the joint surface portion 11 of the joint member 10 is a substantially semicircular shape having an arc R, and its radius L is set to be shorter than the inner diameter of the flange end portion 7D of the base material 7. Therefore, even if the joining angle θ formed between the base materials 7 is any angle, the joining surface portion 11 and the flange end portion 7D are formed.
The length of the joint portion where the welding 6 is performed is always constant with the length of the radius L, the joint strength is constant, and the quality of the product is stable. Further, the protruding piece 13 provided on the lower surface of the bottom surface portion 12 of the joining member 10 is formed by cutting and raising, and the protruding piece 1
The space between the web end portions 7E sandwiching 3 becomes the thickness of the bottom surface portion 12, and the base materials 7 are joined at relatively close positions. Therefore, when the triangular panel frame 2 is formed from the base material 7 and the roof material is attached to this to form the roof panel 1, the base material 7 can be arranged close to the apex of the roof panel 1. Therefore, the roofing material can be supported at a position close to the apex of the roof panel 1, which also improves the strength.
