DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a body of a steel building used for fixing an inclined body edge parallel to a slope of a roof at an arbitrary angle to an upper end of a vertical body edge serving as a base of a wall of a steel building. It relates to an edge connection structure.

2. Description of the Related Art Conventionally, in order to join such body edges, a joining plate is attached to both body edges in advance by welding at a factory, carried to the site, and joined with bolts and nuts. I was

[0003]

For this reason, the rim to which the connecting plate is welded is protruded from the connecting plate and becomes bulky when a plurality of connecting plates are bundled, so that the number of pieces that can be placed on a truck when transported to the site is reduced. There is a problem that the transportation cost increases due to the decrease, the rust preventive paint burns out at the time of welding, so that repainting has to be performed, and the welding causes distortion of the body edge and lowers accuracy. Was.

Means for Solving the Problems, Actions and Effects As a means for solving such problems, the present invention relates to a lip on a body edge made of a lip channel steel having a curved surface.
It is a structure that connects the other body edge made of channel steel at an arbitrary angle, forms a curved surface that adheres to the corner on both sides of the main body, and has a bent piece with a hole at one end parallel to both sides and with the main body. The right angled fastener is shaped like a protruding piece that fits into the opening at the waist edge.
Insert the formed clasp into the fuselage and insert the clasp and fastener
A nut is screwed into a bolt that has passed through, and it is fastened and fixed to one waist edge and the other waist edge. Both bent pieces are joined, and the nut is screwed into the bolt that passes through the hole and tightened. As the coupling plate is fixed on site, it is not bulky during storage and transportation, the storage space is small, transportation costs are low, repainting of rust preventive paint is not required, and both side edges of the coupling plate Since the curved surface is formed so as to be in close contact with the curved surface of the corner of the body edge, the coupling plate does not twist when tightening with the bolt and the nut, and the coupling operation can be performed accurately and quickly.

[0005] Further, in a rim processing factory, a space for welding work and repair painting work is not required, the working environment is improved, and distortion is not caused by welding, so that joining can be performed with high precision. Thus, there is an effect that the coupling angle can be easily changed.

DESCRIPTION OF THE PREFERRED EMBODIMENTS One embodiment of the present invention will be described below with reference to the accompanying drawings.

In the figure, reference numeral 1 denotes a vertical body edge, 2 denotes an inclined body edge, each of which is a lip channel steel having the same cross-sectional shape defined by JIS, and four corners each having a curved surface a.

Numeral 3 is a connecting plate made of a steel plate, having curved surfaces 6 formed on both side edges of a main body 4 having a long hole 5 formed in the center, and forming a right angle with the main body 4 on one side of the main body 4 and having both side edges. A bent piece 7 is formed integrally with the bent piece 7. A hole 8 is formed at the center of the bent piece 7 and radial irregularities 9 centered on the hole 8 are formed on one surface.

Reference numeral 10 denotes a stopper having projections 12 formed at the bent portions at both ends to closely fit the openings of the body edges 1 and 2,
A cut-and-raised portion 11 is formed at the center, and a nut 14 to be described later is formed.
The hole 13 is formed so as to fit tightly.

In order to join the vertical body edge 1 and the inclined body edge 2, first, a connecting plate 3 is applied to the opening side of the upper end of the vertical body edge 1, and a stopper 10 is inserted from above the vertical body edge 1. Then, as shown in FIG. 3, the connecting plate 3 is fixed to the vertical body edge 1 by screwing a bolt 15 passed through the long hole 5 of the main body 4 to a nut 14 fitted in the hole 13 of the stopper 10. I do.

At this time, the curved surface 6 of the connecting plate 3 comes into close contact with the curved surface a at both corners of the vertical waist 1, the protruding piece 12 of the stopper 10 fits into the opening of the vertical waist 1, and the nut 14 Since the bolt 15 is screwed into the nut 14, there is no possibility that the bolt 15 will be twisted.

After fixing the connecting plate 3 to the inclined body edge 2 in the same manner, as shown in FIG. 2, the bent pieces 7, 7 are joined, bolts 16 are passed through the holes 8, 8, and the vertical Rim 1
The nut 17 is screwed together by arbitrarily adjusting the angle with respect to, and tightened and fixed.

At this time, since the radial unevenness 9 is formed on the joint surface of the bent pieces 7, 7, they are engaged with each other so as not to rotate easily.
