Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a protective material suitable for packing wall panels used in bathroom units of hotels, condominiums, general houses and the like, and a method of packing wall panels.

[0002]

2. Description of the Related Art When a bathroom unit is installed and installed in a hotel, an apartment, or the like, in many cases, a corner support is provided at a corner of a waterproof floor and a flat support is provided at a flat surface in a field work, and a wall panel and a door are fitted and fixed. The ceiling unit is placed on the upper part, the inside of the bathroom unit is provided with a bathtub on one side, a washing place on the other, and auxiliary facilities such as water supply, hot water supply, lighting, ventilation, drainage, etc. are completed. Let it.

[0003] The components of the bathroom unit include a waterproof floor, a bathtub, a wall panel (usually a metal reinforcing material is attached to the surrounding back surface), a door, a ceiling, and the like.
These are assembled after they are individually brought to the site. Among these, the wall panels are thin and large (thickness:
(About 5 mm, height: about 2 m, width: about 1 m). In particular, it must be protected from damage during transportation and from collapse due to cargo collapse. FIGS. 6 (protection of one wall panel) and FIG. 7 show a conventional example of a packing method for protecting a wall panel.
(Protection of two wall panels). As shown in FIGS. 6 and 7, a long corrugated cardboard 13 having a U-shaped cross section serving as a protective material is mounted on both side surfaces in the longitudinal direction where there are many breaks, and a plurality of band-shaped cords are perpendicular to the longitudinal direction of the corrugated cardboard. 14 (made of a synthetic resin such as polyethylene).

[0004]

However, the above-mentioned method has a problem that the packing operation requires time, and the use of a long corrugated cardboard and a belt-like string increases the cost. An object of the present invention is to provide a wall panel of a bathroom unit that can be easily and quickly packed, protect the wall panel from vibration and collapse during transportation, and provide an inexpensive wall panel protection material.

[0005]

SUMMARY OF THE INVENTION The present invention is a protective material for a wall panel having a substantially U-shaped cross section comprising an upper surface, a lower surface, and a rear surface. There is a cutout of 90 °, the upper and lower ends have protrusions in the inner longitudinal direction, respectively, and the back has a folding line that can be bent inward with a line connecting the two starting points. It is a protective material for a wall panel. The protective material for a wall panel preferably has a cushion piece provided on the inside of the rear surface thereof.

The present invention also relates to a wall panel with a reinforcing material, which is overlapped on the front surface (decorative surface) of the wall panel, and the side wall and the corner around the wall panel are provided with the above-mentioned protective material for a wall panel. The present invention also relates to a method for packing a wall panel, characterized in that the panel is mounted.

[0007]

BEST MODE FOR CARRYING OUT THE INVENTION The material of the wall panel protective material of the present invention is preferably a flexible synthetic resin in consideration of moldability, wall panel protection performance, strength and economy. Examples of such synthetic resins include general-purpose plastics such as polyethylene, polypropylene, polyvinyl chloride, acrylic resin, methacrylic resin, and polycarbonate.
Further, the wall panel protective material of the present invention can be made into an integrated structure by temporarily forming each part which is a component and then connecting the parts with a connecting tool or an adhesive material. Considering the properties, economy and the like, it is preferable to integrally mold using a mold (die). As the molding method, an injection molding method widely used in resin molding can be used.

FIG. 1 is a perspective view of a protective material for a wall panel according to an embodiment of the present invention. FIG. 2 is a front view (a), a plan view (b), a right side view (c) and a rear view ( d). The left side view is symmetrical with the right side view (c), and the bottom view is symmetrical with the plan view (b), and is omitted in FIG. Although the thickness of the protective material varies depending on the type of synthetic resin used, it is about 2 mm, about 4 mm in a thick part, and about 0.5 mm in a broken line part.

As shown in the figure, the outer shape has a substantially U-shaped cross section including an upper surface 2, a lower surface 3 and a back surface 4, and the two opposing surfaces (upper surface 2 and lower surface 3) each have a starting point at the center of the ridge line. A notch 6 (in the direction of 45 ° with respect to the ridge) is vertically opposed to each other, and wedge-shaped protrusions (continuous in the inner longitudinal direction, respectively) are provided at the ends of two opposing surfaces (upper surface 2 and lower surface 3). Locking piece) 5. The wedge-shaped projection is for holding the wall panel so as not to come off. In addition, the back surface 4 is provided with a broken line 7 that can be bent inward by a line connecting the two starting points. The polygonal line can be provided by making the thickness of the member thinner than other portions.

[0010] Also, on the inside of the back of the protective material for the wall panel,
A cushion piece 8 as shown in FIGS. 1-2 can be provided. This cushion piece is for absorbing vibration and the like during transportation of the wall panel.

The protective material for a wall panel of the present invention (FIG. 1) can be used as a protective material for a wall panel at a corner portion when it is bent inward by 90 ° along a broken line as shown in FIG.

When the protective material for a wall panel according to the present invention is mounted on a wall panel, first, as shown in FIG. Protective members for wall panels (1a) are inserted into the plurality of appropriate places on the side from their open portions, and the projections (locking pieces) are fitted and locked to the metal reinforcing material of the wall panel 11. next,
The wall panel protective member (1b) is bent at 90 ° by a fold line, and its opening is inserted into the corner, and the projection (locking piece) of the wall panel protective member is fitted to the metal reinforcing member of the wall panel 11. To stop. FIG. 5 shows a sectional view of a fitting portion between the wall panel and the protective material for the wall panel.

When the wall panel protective material is removed from the package at the site, the flexibility of the wall panel protective material is used.
Apply force to open both ends of the open part of the wall panel protective material lightly outward. Then, the projection (locking piece) comes off the metal reinforcing material.

The wall panel protective material of the present invention is suitable for packing in a single layer (two wall panels) as in the above-described example. It is also possible to pack the wall panels in a stack.

[0015]

The protective material for a wall panel according to claim 1 or 2 is
It is only necessary to insert and fit this into the side or corner of the wall panel, and the packing operation can be facilitated in a short time. Also,
The same protective material for the wall panel can be used for both the side portion and the corner portion, and can be reused. Therefore, it is economical. Furthermore, not only the bathroom unit wall panels,
It can be used commonly for wall panels that have reinforcements around the panel. According to the packing method of the third aspect, it is possible to easily and quickly pack various wall panels having a reinforcing material around the panel, including the wall panel of the bathroom unit. In addition, the wall panel can be protected from damage due to vibration during transportation and collapse of the load.
