Since the prefabricated storage box according to the present invention uses plate members made of corrugated cardboard, it may be difficult for the shape and size of the plug pin insertion holes to provide a position to insert the plug pins at all times. In other words, the corrugated paper is a paper cardboard attached to both sides of the corrugated corrugated corrugated corrugated, so there is a lot of empty space inside. When the plug pin insertion hole is drilled into the plate member containing such a large amount of space, the structure is relatively small. If a hole (insertion hole) is applied to a weak part, when the plug pin is inserted into the hole, the plug pin may not be properly pressed and the contact friction force may be weakened.

If the plug pin is loosely coupled, the overall strength of the storage box may be lowered. To prevent such side effects, the inventor first inserts and fixes a sleeve socket 170 into the plug pin insertion holes of each plate member. The plug pin 5 is inserted into the sleeve socket 170. As shown in FIG. 24, the sleeve socket 170 is inserted into the plug pin insertion hole 13d formed at the engaging portion of the plate member (for example, the left side plate 13), and then the plug pin (inside the sleeve socket 170) is fixed. Inserting 5) can prevent the plug pin 5 from being shaken or accidentally dropped.

Here, the sleeve socket 170 has a cross-sectional shape corresponding to the plug pin 5 so as to be interference fit, both ends may be an open shape, or one side may be blocked. In addition, it is preferable that an adhesive or an adhesive is applied to the outer circumferential surface of the sleeve socket 170 in advance so that the sleeve socket 170 does not fall out again after being inserted into the plug pin insertion hole of the plate members.

FIG. 25 shows a modification of the sleeve socket 170 shown in FIG. 24. The protrusion piece 171 is formed on the outer circumferential surface of the sleeve socket 170 to once the sleeve socket 170 into the plug pin insertion hole of each plate. ) Is inserted so that it does not come off easily. Figure (a) of Figure 25 shows the coupling relationship between the plug pin 5 and the sleeve socket 170 in a perspective view, Figure (b) is shown in front view form.

In the case of FIG. 24 described above, an adhesive or an adhesive is applied to the outer circumferential surface of the sleeve socket 170 so that the sleeve socket 170 itself is attached to the cardboard tissue. 171 is formed to protrude in an inclined direction so that the protrusion pieces 170 are not easily caught by the cardboard tissue after the sleeve socket 170 is inserted into the plug pin insertion hole. Even in the case of the sleeve socket 170 of FIG. 25, it is possible to apply an adhesive material or an adhesive material to the outer circumferential surface thereof.

Fig. 26 shows a prefabricated storage box 1d using corrugated cardboard according to the third embodiment of the present invention, and Velcro tapes 112, 113, and 122 at the engaging portions between the plates 11, 12, 13, and 14 are shown. , 123, 132, 142, 152 shows an example applied.

1 and 25, the adhesive tape is used to bond the plate members of the prefabricated storage box. In FIG. 24, Velcro tape ("Velcro" is a trade name, also commonly referred to as "sticky"). An example of joining the plate members by using a fiber coupling means that can be easily coupled and separated as shown in FIG.

Referring to FIG. 26, Velcro tapes 112, 113, 122, 123, 132, 142, and 152 are provided at respective coupling portions of the adhesive tapes shown in FIGS. The plate members 11, 12, 13, and 14 may be coupled to each other by bonding tapes.

As described above, the prefabricated storage box using the corrugated cardboard according to the present invention does not use an adhesive containing harmful volatile substances such as formaldehyde, and thus does not adversely affect the human body, and may be used safely in a closed indoor environment. There are advantages to it. In addition, since the corrugated paper used in the present invention can be produced by recycling waste paper, it does not have anything to do with damaging the earth's natural environment by causing wood felling, as in the case of using existing wood, plywood, particle board, and the like.

At present, Korea's environmental policy recommends the use of eco-friendly materials, and classifies SE0, E0, E1, and E2 grades according to the amount of formaldehyde emitted for each material. E1 and E2 grades are referred to as non-environmental materials, where SE0 grades represent less than 0.3 mg / l formaldehyde emission, E0 grades less than 0.5 mg / l, E1 less than 1.5 mg / l, And E2 is 5.0 mg / L or less. Plywood, chipboard, particle board, MDF, etc., which are widely used for manufacturing furniture, contain large amounts of formaldehyde and volatile organic compounds, and thus were environmentally friendly materials with E1 or E2 grades.

However, since the prefabricated storage box according to the present invention uses eco-friendly corrugated cardboard material, it corresponds to the eco-friendly material grade of SE0 or E0, and it does not emit harmful substances.

On the other hand, the prefabricated storage box according to the present invention can be easily coupled to each plate member by using a double-sided adhesive tape or Velcro tape, in particular by fitting the coupling position between the two plate members to be joined using a plug pin The biggest feature is that the engagement position between the plate members can be set accurately and without mistakes.

In addition, the prefabricated storage box according to the present invention provides sufficient strength by the overlapping structure of the corrugated cardboard, there is an advantage that can be extended by connecting the storage boxes in a multi-stage or multi-layer in any number up and down or left and right directions.
