And forming a concave portion projecting further downward than the concave portion formed by the first and second steps in the first to third steps.

Hereinafter, a method of manufacturing a pressing head of a fastening fastener according to the present invention will be described in detail with reference to the accompanying drawings.

FIG. 1 is a view showing a manufacturing process of a pressing head of a fastening fastener of the present invention, and FIG. 2 is a sequence diagram of a mold for manufacturing a pressing head of a fastening fastener of the present invention.

The present invention relates to a hull comprising: a fixing pin (110) fixed to a hull on which a grating is installed to fix a grating installed on an upper surface of a water channel formed on a hull; a polygonal plate-shaped pressing head (130) seated on the upper surface of the grating; And a fixing nut 120 coupled to the pin 110 to allow the pressing head 130 to press on the upper surface of the grating.

Accordingly, the pressing head 130 is formed by vertically protruding the central portion of the semi-finished product formed in the shape of a sawtooth plate by a one-

Figure 112016014939940-pat00004
'Shape.

In the second step, a plurality of through holes 133 are formed at the edge of the semi-finished product so as to be spaced apart from each other by a predetermined distance in the circumferential direction,

Figure 112017065416510-pat00021
'Shape.

Thereafter, in the third step process, a center hole 132 is formed at the center of the semi-finished product,

Figure 112017065416510-pat00022
'.

Further, in the four-step process, the vertex portion of the semi-finished product is bent downward,

Figure 112016014939940-pat00007
.

Bending the vertex portion of the semi-finished product downward is to more effectively fix the grating by lowering the vertex portion downward.

Meanwhile, between the steps 2 and 3, the through-holes 133 formed in the semi-finished product are formed so as to protrude upward,

Figure 112017065416510-pat00023

The engaging pieces 114 limit the degree of insertion of the insertion portion 112 when the hull is inserted into the hull.

At this time, the upper surface of the latching piece 114 is formed to be inclined downwardly by about 15 degrees from the edge of the pin body 111 toward the edge of the latching piece 114. When the insertion portion 112 is inserted into the hole of the hull, The lower surface of the latching piece 114 is pressed against the bottom of the hull so that the overall shape is leveled.

A nut rod 120 is fastened to a threaded portion 113 of the fixing pin 110. The nut rod 120 has a threaded portion 113 of the fixing pin 110 on the lower surface of the nut rod body 121, And a fixing member 123 having a larger diameter than the nut body 121 is formed at the upper end of the nut body 121. [

The nut rod 120 is inserted into the central hole 132 formed at the central portion of the pressing head 130 in the form of a sawtooth plate so that the nut hole 122 of the nut rod 120 and the upper The pressing head 130 includes a polygonal plate member 131, a central hole 132 formed to penetrate the plate member 131 in the vertical direction, And a plurality of through holes 133 formed at the edge of the center hole 132 and spaced apart from each other in the circumferential direction around the center hole 132.

At this time, the plurality of through-holes 133 formed in the pressing head 130 is used for dripping.

In detail, the fixing pin 110 is inserted into the drainage passage of the hull where the grating is installed. At this time, after forming a hole in the hull, one end of the fixing pin 110 may be inserted.

The nut rod 120 is inserted through the center hole 131 formed at the center of the pressing head 130 so that the nut rod 120 is inserted into the center hole 131 of the pressing head 130, The lower surface of the pressing head 130 is brought into contact with the upper surface of the grating so as to fix the grating when the nut hole 122 formed on the lower surface and the threaded portion 113 formed on the fixing pin 110 are fastened.

As described above, the present invention has a remarkable effect in that it is easy to manufacture, the grating can be fixed easily, and the grating can be fixed very firmly.
