Description

[Detailed Description of the Invention] [Industrial Field of Application] The present invention relates to a connecting part for metal tarpaulin used in horizontal roofing construction of metal roofing sheets.

[Prior Art] A so-called octagonal sheet metal sheet 12, which is bent into an octagon as shown in FIG. 4 and whose both ends 11 are bent outward at the lower surface, is known as a metal sheet. A sheath-shaped joint 14 formed by folding back both sides 13 of a flat plate upward is also known as a connecting member between such octagonal tarukis.

Alternatively, a method is also known in which a cylindrical joint 15 is inserted into an octagonal bracket to connect two brackets.

[Problems to be solved by the invention] However, in the case of conventional joints, for example,
When using the sheath-shaped joint 14 shown in FIG.
(Fig. 6), and it is also necessary to cover the protective cover 16, but in such a case, if the joint exists on the lower surface of the tarpaulin, it will be a hindrance.

Furthermore, when a long roll-formed taruki is cut, the cut portion expands slightly due to internal stress. Therefore, this sheath-like joint 14 becomes difficult to insert, and therefore the joint must be made wide, which makes it more unsightly.

Furthermore, the cylindrical joint 15 shown in FIG.
It is difficult to form a stopper to prevent the joint from sliding, which is required during this insertion. Furthermore, since the joint is circular, it has the disadvantage that it protrudes from the underside of the tarpaulin.

[Means for Solving the Problems] Therefore, the present invention forms a joint in an octagonal shape having an opening on the lower surface, which is almost the same shape as the taruki, and
A reinforcing plate is attached to the opening on the bottom surface, and this joint is inserted into the tally to connect two tallys.

By doing this, even if pressure is applied to the joint, the joint will not collapse. Further, since the lower surface is open, a convex portion, that is, a stopper can be formed on the upper surface.

[Example] The center of the lower surface of the octagonal pipe 1 is cut, and the cut pieces 2 and 3 on both sides are respectively bent inward and finished in parallel with a space between them.

A long reinforcing plate 5 having ears 4 projecting at appropriate intervals on both sides is mounted between the parallel cut pieces 2 and 3. The parallel cut pieces 2 and 3 include:
Engagement holes are provided at positions corresponding to the ears 4 of the reinforcing plate 5, respectively, so that the two engage with each other. A convex stopper 6 is provided at the center of the upper surface of the tall joint 1.

When connecting the deck, one end of the joint 1 is inserted into the deck 12, and the other end is inserted into the deck, as shown in FIG. At this time, due to the presence of the stopper 6 protruding from the upper surface of the joint 1, there is no possibility that the joint 1 will sink into one of the sockets more than necessary.

[Effects of the invention] Since the present invention is constructed as described above, it has a structure that allows processing work to be done to protrude the stopper 6 from the inside to the outside on the upper surface of the joint 1, and after connecting the taluki, the stopper 6 on both sides It fits snugly inside the tarpaulin, giving it a good appearance, and does not get in the way when removing the fireproof protective cover.

There is a reinforcing plate inside the joint, so it can be used even if external pressure is applied to the entire deck. without collapsing,
Therefore, there is no unseemly appearance of it protruding from the lower opening of the taruki.

Claims (1)

[Scope of utility model registration request] It is a joint made of octagonal taruki, in which the center of the lower side of the octagonal pipe is cut, the cut pieces on both sides are bent inward, and both pieces are stood up in parallel with a gap between them. Engagement holes are provided at appropriate intervals in both parallel cut pieces, and a long reinforcing plate having protruding ears on both sides at positions corresponding to the holes is engaged with the holes and the ears, respectively. A metal tarp joint that is attached between both cut pieces.
