Nip the edge of the roof panel 6.

Next, the structure of the cross connection device between the purlin 4 and the lower member 5a of the rafter 5, which are the two long members, will be described in detail with reference to FIG. The purlin 4 is formed in a substantially rectangular cylindrical shape, and has a protruding edge 42 extending upward at one widthwise end of an upper surface wall 41 serving as a contact surface with the lower member 5a, and the protruding edge is a lower member. The portion connected to 5a has a cutout portion 43 cut out over a length equal to the width of the lower member. In the upper wall 41 of the purlin, fitting recesses 44 are formed at two positions on the left and right sides of the upper part of the purlin at an intermediate portion in the width direction and separated from each other in the width direction. The right and left fitting recesses 44 have inclined surfaces 44a that gradually approach each other toward the bottom thereof, and have locking portions 44b that are bent at the lower ends of the inclined surfaces in directions away from each other.

Reference numeral 8 denotes a connecting bracket which is an important component in the present invention. The connection bracket 8 has a flat plate-shaped fixing portion 81 at the center, and a fitting projection 82 protruding upward is provided on the upper surface of the center of the fixing portion. The fitting projection is formed in a glans shape divided by a central slit, and has elasticity. Further, return portions 83 are formed integrally from both ends in the width direction of the fixing portion 81 and extend in opposite directions to each other with a required inclination with respect to the fixing portion. Further, there are left and right fitting projections 84 extending downward from both ends of the fixing portion 81 or from the vicinity of the base ends of the two return portions 83. The fitting projections 84 are inclined so as to be gradually separated from each other toward the lower end, and the lower end thereof has an engaged portion bent in the same direction as the bending direction of both the engaging portions 44b of the purlin 4. Part 8
Five.

On the bottom surface of the lower member 5a of the rafter 5, a concave groove 54 having a width L2 substantially equal to the width L1 of the connecting bracket is formed at a central portion in the width direction. (Which is also the bottom of the fitting recess 51)
A fitting hole 55 is formed at a position where the upper member is connected to the purlin. The diameter of the fitting hole 55 is slightly smaller than the maximum diameter of the fitting projection 82 of the connection bracket.

In order to attach the connecting bracket 8 to the upper member 5a in this manner, one of the return portion 83 and the fixing portion 81 of the connecting bracket 8 is fitted into the concave groove 54, and the concave groove 54 is fitted.
The upper member 5 faces the fitting hole 55 in a state where the upper
When it moves in the longitudinal direction of a, the upper end of the fitting projection 82 of the connecting bracket is fitted into a part of the fitting hole 55 and stopped. Therefore, at that position, the connecting bracket 8 is
a, the fitting protrusion 82 is elastically deformed and its maximum diameter becomes substantially equal to the diameter of the fitting hole 55 due to the presence of the slit. And it is connected in a state where it cannot fall off due to elastic restoration. When the connecting bracket 8 is properly attached to the upper member 5a, at least the distal end of the return portion 83 projects downward from the lower surface of the upper member.

In order to connect the upper member 5a with the connecting bracket 8 attached thereto to the purlin having the fitting recess 44, the upper member 5a crosses the cutout 43 of the purlin 4 at a predetermined angle, and 8 with the fitting projections 84 facing the fitting recesses 44 of the purlin, and
Press strongly toward.

The projecting length (height) of the fitting projection 84 of the connecting bracket 8 is equal to the distance from the opening surface of the fitting recess 44a of the purlin to the locking portion 44b, and the opening of the fitting recess 44a. The distance from the surface to the bottom is set slightly larger than the length of the fitting projection 84. However, the return unit 83
Is perpendicular to the horizontal plane passing through the lower end of the fitting projection 84. The vertical distance from the opening surface of the fitting recess 44a of the purlin to the locking portion 4
It is set slightly smaller than the vertical distance up to 4b.

With the above configuration, the upper member 5a is
When pressed against, the fitting projection 84 of the connection bracket moves toward the lower end of the fitting recess 44 while being shifted in a direction approaching each other by the inclined surface 44a of the fitting recess 44 of the purlin. The tip of the return portion 84 is the upper wall 4 of the purlin 4.
When the upper member 5a is further pressed after the projection 1 is provided, when the return portion 84 is elastically deformed and becomes parallel to the fixing portion 81, the lower end of the fitting projection 84 of the connection bracket is fitted into the fitting recess. Since the locking portion 85 at the lower end of the fitting protrusion comes off the lower end of the inclined surface 44a at that time, the fitting protrusions move in the direction away from each other. Thereafter, when the pressing force is released from the upper member 5a, the return portion 83 of the connection bracket is elastically returned.
An attempt is made to move the fitting projection 84 upward. Therefore, the locked portion 85 of the connecting bracket is locked by the locking portion 44b of the purlin, and that state is maintained.

That is, since the fitting convex portion 84 is fixed to the fitting concave portion 44 so as not to be able to move in the vertical direction by the locking portion 44a and the locked portion 85, the wind blowing on the roof of a simple garage or terrace can be used. Even when factory vibration, traffic vibration, or noise vibration on the ground acts on the upper member 5a, it is possible to prevent the upper member from vibrating slightly with respect to the main building and generating chattering noise during the vibration.

The fixing portions 86 protruding from both ends of the lower surface of the fixing portion 81 of the connecting bracket 8 are connected to the connecting bracket 8.
Is inserted into the fitting recess of the purlin, it fits into the portion of the upper wall 41 of the purlin 4 that is present between the opening surfaces of the fitting recesses, and prevents the connecting bracket from moving in the width direction of the purlin. It is for. However, the angle of inclination of the fitting protrusion 84 is smaller than the angle of inclination of the inner wall surface 44c of the fitting recess 44, and the distance between the base ends of the fitting protrusion 84 is set to be equal to the distance between the upper wall 41 of the purlin 4. When the width is equal to the width of the portion existing between the opening surfaces of the combined concave portions, the fixing portion 86 becomes unnecessary.

In the above embodiment, the fitting projection 82 and the fitting hole 55 are used for attaching the connecting bracket 8 to the upper member 5a.
Is used, there is an advantage that the connection between the connection bracket and the upper member does not require screws and tools. But,
Since the connecting bracket can be fixed to the upper member in advance on the ground, as shown in FIG.
The fixing portion 81 may be fixed to the lower surface of the upper member 5a by riveting or screwing using a member provided with a hole 82e.

Although the above embodiment is applied to the cross connection of a roof purlin and a rafter, the present invention can be widely applied to the cross connection of two long members. .

As described above, according to the present invention, the connecting bracket is attached to the connecting surface of one of the long members,
Just press the one long member toward the other long member with the mating convex portion of the connection bracket facing the mating concave portion of the connecting surface of the other long member. Can be linked. Therefore, the connecting operation can be easily performed without tools, and the connecting operation at a high place can be performed safely and quickly, particularly, as in the case of connecting the roof purlin and the rafters.
