Description

DETAILED DESCRIPTION OF THE INVENTION [Object of the Invention] (Field of Industrial Application) The present invention relates to a corrugated plate mounting tool for mounting a corrugated plate on a support member.

(Prior Art) A roof such as a terrace or a garage is generally constructed by attaching a corrugated sheet to a frame of a roof as a supporting member so as to cover the frame. In this case, the corrugated plate mounting tool for mounting the corrugated plate on the skeleton of the skeleton includes a head and a plastic hook portion projecting from the head and penetrating the corrugated plate and locked to the skeleton. Are used.

(Problems to be Solved by the Invention) However, in the above-described conventional configuration, since the hook portion of the corrugated plate attachment is formed by the rod-shaped body having a simple round or square cross section, the overall strength of the hook portion is low. There was a problem that it was not very strong. Also, the hook part is made of plastic and is molded, but when molding plastic water is poured into the cavity of the mold, air bubbles may be trapped in the mold cavity. There is a problem in that "sus" occurs due to the bent portion having an acute angle and the strength is further reduced.

SUMMARY OF THE INVENTION Therefore, an object of the present invention is to provide a corrugated plate mounting tool that can increase the overall strength of the hook portion and prevent the occurrence of "squash" as much as possible.

[Means for Solving the Problems] (Means for Solving the Problems) The present invention is a corrugated plate mounting tool for mounting a corrugated plate on a support member, which includes a head and a corrugated plate penetratingly provided on the head. And a hook portion made of plastic for engaging with the support member, and the hook portion is formed in a shape having a groove portion extending in the axial direction on the outer side.

(Operation) Since the hook portion is formed in the shape having the groove portion extending along the axial direction on the outer side, the hook portion has a structure in which the reinforcing rib extends in the axial direction and projects so as to sandwich the groove portion. It is possible to increase the overall strength of the hook portion as compared with the conventional one having a simple rod-shaped hook portion. Further, when molding the hook portion, the cavity of the die becomes smaller by the amount of the above-mentioned groove portion, and the amount of air existing in the cavity also decreases, so when the hot water of the plastic is poured into the cavity, Air is almost never trapped inside.

(Embodiment) An embodiment of the present invention will be described below with reference to the drawings.

First, in FIGS. 1 to 3, reference numeral 1 denotes a head, which is composed of, for example, a circular plate portion 1a and a knob portion 1b integrally projecting upward from the upper surface of the plate portion 1a. The grip portion 1b has a thin base portion 1c and a thin base portion 1c, and can be cut by the narrow thin portion 1c. Furthermore, the surface is subjected to so-called knurling. Has been done. Reference numeral 2 denotes a hook portion, which is integrally provided so as to project downward at the center of the lower surface of the head 1 in FIG. As shown in FIG. 4, the hook portion 2 is formed in the shape of a shaft member having a substantially H-shaped cross section having groove portions 2a extending along the axial direction on the outer side, for example, on both sides. The tip portion 2b is bent and formed obliquely upward.
The head portion 1 and the hook portion 2 are molded from plastic and integrally molded, thereby forming the corrugated plate mounting member 3.

Now, a case where the corrugated plate is attached to the supporting member by the corrugated plate attaching tool 3 will be described with reference to FIGS. 5 and 6. In FIGS. 5 and 6, reference numeral 4 denotes, for example, a corrugated plate made of plastic, and 5 denotes a supporting frame that constitutes a supporting member, for example, a frame of a roof, and the corrugated plate 4 is placed and supported on the supporting frame 5. It Here, a mounting hole 4a for inserting the hook portion 2 of the corrugated plate mounting member 3 is formed in the corrugated plate 4, and the fulcrum 5
Has a substantially U-shaped cross section, for example, and an engaging piece 5a is formed by folding back at the upper end of the left side wall in FIG.
Then, with the corrugated plate 4 placed on the fulcrum 5, the hook portion 2 of the corrugated plate fixture 3 is inserted into the mounting hole 4a of the corrugated plate 4, and the head portion 1 is grasped while pinching the knob portion 1b with fingers. The tip portion 2b of the hook portion 2 is rotated and locked to the engaging piece portion 5a of the fulcrum 5.
As a result, the corrugated plate 4 is attached and fixed to the skeleton 5, and a roof such as a terrace or a garage is constructed. And then
In the state where the hook portion 2 is locked to the fulcrum 5, that is, in the fixed state of the corrugated plate attachment 3, the knob portion 1b is further twisted and further turned one to several times to cut it. Incidentally, 6 is the head 1 and the corrugated plate 4.
It is a washer made of an elastic material such as a sponge interposed between and.

According to this embodiment having such a configuration, the hook portion 2 is formed in a shape having a substantially H-shaped cross section having groove portions 2a, 2a extending along the axial direction on both sides. Since each of the two reinforcing ribs 2c sandwiches the groove portions 2a, 2a and extends in the axial direction and is projected (see FIG. 4), compared to the conventional structure including the hook portion of a simple rod-shaped body. The overall strength of the hook portion 2 can be increased. Also, the hook 2
At the time of molding the mold, as shown in FIG. 7, the cavity 9 formed by the upper mold 7 and the lower mold 8 becomes smaller by the amount of the above-mentioned groove 2a, and the amount of air existing in the cavity 9 becomes smaller. Since the amount is reduced, when the plastic hot water is poured into the cavity 9 and flows, the air is less trapped in the cavity 9 and the air is hardly trapped. It is possible to prevent the occurrence of "sun" in the bent portion 2d (see FIG. 1) as much as possible, and thus the strength of the hook portion 2 can be further increased.

[Effects of the Invention] As is apparent from the above description, the present invention includes a head portion and a plastic hook portion projecting from the head portion and penetrating the corrugated plate to be locked to the support member. Since the hook portion is formed in a shape having a groove portion that extends along the axial direction on the outer side portion, it is possible to increase the overall strength of the hook portion, and at the same time, when the hook portion is molded, there is a possibility that "squash" may occur. This has the excellent effect that the strength of the hook portion can be further increased by preventing it as much as possible.
