Hereinafter, it will be described based on the embodiment showing the present invention.

Figure 2 shows the overall perspective view of the prefabricated wiring protection duct of the present invention, the upper cover part (1) holding the tongs portion 4 placed on both ends of the tongs outer portion (4a) and the inner side of the tongs (4b) facing each other And a lower lid portion 1a obtained by continuously drilling the screw holes 10 at regular intervals in the longitudinal direction of the upper lid portion. In the manufacture of the upper lid portion 1 and the lower lid portion 1a, one mold frame is sufficient, and only the lower lid portion 1a can be obtained by forming the screw hole 10 by post-processing such as punching. In addition, the sidewall holes 3 are held at regular intervals in the longitudinal direction of the sidewalls 2, and the sidewall grooves 7a, 7b, and 7c are formed in the upper, middle, and lower portions of the sidewall pillars 11, respectively. An arrow-shaped portion 9 is formed in the side wall extension part 6 extending upward from the side wall groove 7a in the upper part of the side wall column 11, and the upper side wall 5 of the side wall. Since the upper and lower cover parts 1 and 1a and the left and right side walls 2 and 2 can be completely separated, the cover 1 and the side wall 2 each having a standard can be mixed with each other. The specification can produce prefabricated wire protection ducts of various sizes.

Figure 3 shows the coupling portion between the upper and lower cover parts 1, 1A and the left and right side walls 3, 3 of the prefabricated wire protection duct of the present invention, and an arrow-shaped part 9 at the upper end of the side wall 6. ) Is positioned at both ends in the width direction of the upper cover portion 1 and is inserted into the tongs portion 4 protruding in the vertical direction to the upper cover portion 1, and the four portions of the prefabricated wire protection duct are coupled to each other. Are different, but the combination is the same. Arrow-shaped portion (9) is an arrow-shaped end is easy to insert into the forceps. And, the arrow catching portion (9a) of the arrow-shaped portion (9) at the upper end is easy to move away after insertion in the form of a gentle curve, the arrow catching portion (9a) of the arrow-shaped portion (9) at the bottom is angled It is hard to be removed after insertion because it is in a true shape. Therefore, when the upper cover 1 of the assembled prefabricated wire protection duct is removed, the side walls 2 and 2 do not come up together with the upper cover 1.

Fig. 4 shows the sidewall of the assembled wire protection duct of the present invention, which continuously holds the sidewall holes 3 at regular intervals in the longitudinal direction of the sidewall, and the sidewall pillars 11 and the sidewall pillars 11 formed thereby. The side wall columns 11 have the side wall grooves 7a, 7b, and 7c in the upper part, the middle part, and the lower part, respectively, while pushing and pulling the side wall column 3 from the side wall 2 with a finger. Deviation is easy. Therefore, no tools are required as in the conventional work. In addition, the side wall (2) has a side wall extension (6) formed by extending from the side wall groove (7a) of the upper side of the side wall pillar (11) to the upper end, but the lower side of the side wall column (11) The reason there is not is to allow the wires stacked on the lower cover 1a to be pulled out directly without a chin when the wires are drawn out to a lower portion.

Here, the size that can be extended to the upper sidewall 5 of the sidewall hole 3 is not limited to the lower end of the sidewall extension 6 but may rise to the upper end of the sidewall 2.

Depending on the working environment, it may not be necessary to pull the wire through the side wall, so a side wall as shown in FIG. 6 may be used at this time.

FIG. 7 shows the upper end of the side wall column 11 by fully extending the side wall hole 3 between the side wall column 11 and the side wall column 11 of the side wall 2 shown in FIG. The upper side walls 5 are separated from each other. In this way, when the upper ends (upper side walls 5) of the side wall pillars 11 are attached to each other, the inconvenience of having to pull the end of the wire back to the desired part of the side wall to be pulled out and insert the end of the wire can be prevented. have. Since the sidewall hole 3 with the upper end completely formed is formed, the electric wire can be easily withdrawn in any desired part by simply inserting the electric wire from top to bottom therebetween.

FIG. 8 shows the protruding support portions 12 protruding in the vertical direction between the tongs outer portion 4a and the tongs inner portion 4b of the tongs portion 4 shown in FIG. 3, respectively, facing each other. It has a position, and the tip of the arrow part 9 can be inserted and supported therebetween, so that the arrow part 9 can be supported more firmly. It is possible to prevent the warping of the side wall due to the volume outside the side wall.

As described above, according to the prefabricated wiring protection duct according to the present invention, the side wall grooves can be made in the side walls, so that the side wall pillars can be easily removed without tools. In addition, since the top and bottom cover (1), (1a) and side walls (2), (2) are completely separated, By repeatedly stacking flat members instead of shaped members, the space utilization is excellent due to the volume reduction, which leads to a reduction in loading and logistics costs, a reduction in manufacturing and waste disposal costs, and a sidewall ( 2) and the cover (1) can be made of prefabricated wiring protection ducts of various standards, and the arrow engaging portion of each arrow-shaped part is caught on both sides, further strengthening the binding force. In addition, when the upper cover 1 is removed, the lower arrow portion of the arrow-shaped portion 9 of the side walls 2 and 2 prevents the side walls 2 and 2 from adhering to the upper cover 1. The shape of (9a) is an angle to the fork, and the upper arrow engaging portion is made in a semi-circular shape has an effect that can be easily separated only the upper cover (1).
