Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial field of application] The present invention relates to a columnar protective material. More specifically, it relates to a protective material for covering a pillar or a sill so as not to damage a house under construction.

[Prior art] When building a house, etc., pillars, sills, kamoi, etc.
These are collectively referred to as columnar objects), but if you leave them exposed, you can inadvertently damage them no matter how careful you are.

Therefore, conventionally, a disposable protective material for covering the columnar object has been used.

As a conventional protective material, a thin plastic plate is used which is formed in a box shape in cross section so that a pillar or the like can be encased, and has a longitudinal cut on one side. When using it, spread the notch and cover the pillar to cover it.

[Problems to be Solved by the Invention] However, the above-mentioned conventional protective material is too expensive to be disposable because of high material cost and manufacturing cost. Since the material is plastic, it is difficult to dispose of, and in some cases it causes pollution. Protective materials for pillars cannot be used for sills and sills, and those for sills and sills cannot be used for pillars, so they lack versatility and can only be installed if the cross-sectional dimensions and length are exactly the same. Warpage is likely to occur due to temperature changes, and when warpage occurs, the notch opens and the mounting is removed. There are various drawbacks such as.

In view of such circumstances, the present invention is inexpensive, easy to dispose of, has general versatility that can be used not only for pillars but also for sills and sills, and can be used even if the dimensions do not fit properly, and warpage occurs. The purpose of the present invention is to provide a new protective material which is securely attached without any damage and has a high cushioning protection effect.

[Means for Solving the Problems] A columnar object protection material of the present invention is a long corrugated cardboard material having four sides capable of surrounding a columnar object having a rectangular cross section, and one side of the corrugated cardboard material is provided with a notch in a longitudinal direction. Are formed, and the other side is separated in the longitudinal direction.

[Operation] When the protective material of the present invention is used for a pillar, if the separated side is opened and the pillar is covered, it has four sides so that it can completely surround the four sides of the pillar. In addition, since the present invention can cut a protective material into two by cutting the notch, a protective material for U-shaped cross section can be made by covering it with a sill or kamoi. can do. Thus, the protective material of the present invention is versatile.

Since the material of the protective material of the present invention is corrugated cardboard, it can be easily folded by hand or cut by a cutter or the like at hand. Therefore, even if the dimension of the pillar or the like does not match the dimension of the protective material, if the protective material is bent in accordance with the pillar or the excessively long portion is cut off, a slight dimensional difference can be absorbed. In addition, since the corrugated cardboard has a multi-layered structure with a core, warpage is unlikely to occur, and the corrugated paper does not come off the mounting due to the warp. Furthermore, since the multilayer structure having a core absorbs external shock well,
Highly protective effect. Moreover, since the material is paper, it can be incinerated, and no pollution occurs when it is disposed of.

[Embodiment] Next, an embodiment of the present invention will be described.

FIG. 10 is an explanatory view showing a state of cutting (5), and FIG. 10 is a sectional view for explaining a protective member according to another embodiment.

In FIG. 1, (A) is a protective material. The protective material (A) is a long product that has four sides (1), (2), (3), (4) that can surround a columnar shape having a rectangular cross section and that extends in the axial direction. The material is corrugated cardboard, and the corners where each side (1), (2), (3), (4) touches
(C) is bent.

A cutout (5) is provided in the longitudinal direction on one side (2) of the protective material (A). The position where the notch (5) is inserted is preferably a position closer to one corner (C) from the center of the side (2). Notch
The side (4) facing the side (2) where the (5) is formed has a cut (6), and the side (4) is separated into two parts (4a) and (4b). . The position where the notch (6) is made is preferably substantially the same as the position of the notch (5).

Various kinds of corrugated board can be used without particular limitation, but those shown in FIGS. 3 to 5 are preferable. The corrugated board of Fig. 3 is a double-sided corrugated board in which two front and back liners (b) are attached to one core (a). The corrugated board of Fig. 4 has two cores (a) and three liners (b). It is a double-sided corrugated board with liner (b) attached. The corrugated cardboard shown in FIG. 5 is a tri-wall corrugated cardboard having three cores (a) and four liners (b) bonded together. Notches in the above cardboard
The depth of (5) is arbitrary, but if it is deep, the strength decreases, so the depth of the notch (5) may be about half the thickness of the corrugated board, especially in the corrugated board of FIGS.

The size of the protective material (A) may be adjusted to the size of the columnar object to be protected, and the width of one side is usually 105 to 110 mm and the length is 17 mm.
It is 50 to 1790 mm, but it should be easy to use even if it is larger or smaller.

In FIG. 1, (7) is a single-sided adhesive tape. When it is wound around a pillar or the like, the adhesive tape (7) is used by sticking it over the sides (4a), 4b) from the cut (6) as shown in the figure.

Next, how to use the present invention will be described.

The corrugated cardboard (A) of the present invention can be easily folded at the notch (5). Then, as shown in Fig. 2, when the side (2) is bent at the notch (5) and the side (3) is opened outward,
It is easy to install on a pillar (21). In this way, it is attached to the pillar (21) and the state where the entire circumference of the pillar (21) is covered is the sixth.
As shown in the figure. (7) is the above-mentioned adhesive tape,
When the sides (4a) and (4b) are joined in this way, the protective material (A)
Does not fall off the pillar (21). If the protective material (A) becomes unnecessary, the protective material (A) can be easily removed by peeling off the adhesive tape (7). The width of the pillar (21) is the protective material (A).
When the cross-sectional size of the column is smaller, the side (4a) and the side (4b) can be overlapped with each other, or the corner can be newly bent according to the corner of the column (21) to be brought into close contact with the column (21). There may be some gap between the pillar (21) and the inner surface of the protective material (A). Further, the length can be arbitrarily cut or added according to the length of the pillar (21).

Next, the case of using the sill or the Kamoi will be explained.
The protective material (A) of the present invention has a notch as shown in FIG.
If the notch (5) is cut into (5), the protective material (A) can be divided into two along the notch (5). The protective material (B) formed by being divided in two has a U-shaped cross section with narrow sides (4a) and (2a) on both sides of the side (3). The protective material (B) is used by covering the pillar (21) as shown in FIG. 7 or by mounting it on the sill (23) as shown in FIG. See also Kamui (22) (Fig. 6)
Can be attached to. Then, if necessary, an adhesive tape or the like may be used so as not to come off. Even in the case of using this mode, it is possible to adjust the large, small, long, and short dimensions by newly bending a portion different from the existing corner (C), cutting an extra length, and adding a required length by adding.

In the present embodiment as described above, the corrugated paper as a material has a corrugated core (a), which exerts a great cushioning effect in the case of collision with an external force, and therefore protects the pillar and the sill from being damaged. Is very effective for.

After use, it can be easily disposed of by incineration.

Next, another embodiment will be described.

Although the notch (6) is formed on the side facing the notch (5) in the above-mentioned embodiment, it may be formed on another side. For example, as shown in FIG. 10, the I position of side (3) or the II position of side (1)
It may be the position or the III position. These examples use pillars (2
It is useful for protecting 1).
