However, the above-described conventional technique has the disadvantage that it is necessary to manually install the crosslinks and trestles each time a steel column product is handled, resulting in heavy labor and a large amount of work. In addition, wooden crossbars are prone to cracking and chipping, resulting in continuous disposal and replacement costs. Further, in the case of a steel stand, there are drawbacks such as low general versatility in response to changes in product shape specifications, restrictions on how to place the product during storage, and a large area to be used during storage. In addition, the materials storage system disclosed in Patent Document 1 cannot solve the above drawbacks.

In view of the above circumstances, it is an object of the present invention to provide a corner guard that can appropriately protect the corners and floor (ground) of a portable member during storage.

In order to solve the above-described problems, the corner pad of the present invention is a corner pad that is applied to the corner of a portable member having a corner at the end of a plate portion, and includes a cushioning portion that receives the corner. and a mounting portion for holding the state in which the cushioning portion is mounted on the corner portion.

With the above configuration, each corner and the floor surface can be protected by the cushioning portion that receives the corner of the end of the plate portion, and the attachment portion is in a state where the cushioning portion is attached to each corner. This eliminates the drawbacks of using wooden crossbars and structural pedestals.

The plate portion may be a magnetic plate portion having magnetism, and the mounting portion may be a magnetic mounting portion that holds the mounted state by magnetic force. Here, when the mounting portion is, for example, a clip, it is necessary to open the clip, but the magnetic mounting portion can eliminate such an operation.

The mounting portion has a plate shape and may be in surface contact with the plate portion. In particular, when the magnetic mounting portion, which is the mounting portion, is in surface contact with the magnetic plate portion, the magnetic force holding the buffer portion can be increased.

A shaft member may be provided on the plate-shaped mounting portion, and the buffer portion may be supported by the mounting portion by the shaft member inserted through a through hole formed in the buffer portion. According to this, the buffer portion and the mounting portion are integrated by the shaft member.

A plate member may be arranged to face the plate-like mounting portion so as to sandwich the buffer portion, and the plate-like mounting portion and the plate member may be connected by the shaft member. According to this, the buffer portion is stably supported by being sandwiched between the mounting portion and the plate member.

The cushioning portion and the mounting portion may be provided separably. According to this, when the buffer portion or the like is damaged, the buffer portion or the like can be replaced.

Moreover, in these configurations, a portion of the cushioning portion that receives the corner portion may have an inclined surface corresponding to the angle of the corner portion. According to this, the contact area between the part receiving the corner and the corner can be made as large as possible, and it is possible to prevent an excessive burden from being applied to a part.

A curved surface portion may be formed at a portion of the cushioning portion opposite to the portion that receives the corner portion. According to this, the buffer part can be stably brought into contact with the floor or the ground.

According to the present invention, each corner and the floor surface can be protected by the cushioning portion that receives the corner of the portable member. Therefore, there is no need to use wooden crossbars or structural mounts, and there is an effect that the drawbacks of using these can be eliminated.

An embodiment according to one aspect of the present invention will be described below with reference to the accompanying drawings.
As shown in FIGS. 1 and 2 , the corner pad 1 of this embodiment includes a cushioning portion 11 and a magnetic force mounting portion 12 . The buffer part 11 is brought into contact with the corner of the portable member, and the magnetic mounting part 12 holds the state in which the buffer part 11 is mounted on the corner by magnetic force. 3, for example, the H-shaped steel beam 31 is preliminarily welded to the square steel pipe column 32, and the H-shaped steel beam 31 is attached to the flange of the H-shaped steel beam 31 in the column product 3 as a portable member. It is used to protect the corner 31b at the end of 31a. In this case, when the column product 3 is stored, the two H-shaped steel beams 31 located on the lower side of the square steel pipe column 32 at intervals of 90 degrees face the floor or the ground. The corner pad 1 is attached to the corner portion 31b of the end portion of the upper or lower flange 31a of the H-shaped steel beam 31 . The H-shaped steel beam 31 is a steel product, and the flange 31a serves as a magnetic plate portion having magnetism.

The buffer portion 11 is made of, for example, a polyamide resin called 6 nylon (for example, "MC Nylon (registered trademark)" manufactured by Quadrant Polypenco Japan). In addition, at a portion of the cushioning portion 11 that receives the corner portion 31b, an inclined surface is positioned in a substantially V shape at an angle (for example, 90 degrees) corresponding to the angle (for example, 90 degrees) of the corner portion. A concave portion 11a is provided. The bottommost portion of the recessed portion 11a is formed with a radius instead of a corner so that stress concentration is less likely to occur. Moreover, the thickness of the buffer portion 11 is set to, for example, about 50 mm.

A curved surface portion 11b is formed on the opposite side of the concave portion 11a of the buffer portion 11. As shown in FIG. In this example, the curved surface portion 11b is positioned not directly below the bottommost portion of the recessed portion 11a, but at a position inclined by 45 degrees, for example. Therefore, when the corner portions 31b of the two H-shaped steel beams 31 spaced apart by 90 degrees are set in the concave portion 11a of the buffer portion 11, the curved surface portion 11b faces the floor side or the ground side. Become.

The magnetic force mounting portion 12 is composed of a plate member 12a and a magnet sheet 12b adhered to the plate member 12a. That is, the magnetic force mounting portion 12 has a plate shape, and the magnetic sheet 12b is in surface contact with the flange 31a. The magnet sheet 12b is attached above the buffer portion 11 of the plate member 12a. The lower end of the plate member 12a is located above the lower surface of the buffer portion 11 and has the same curved shape as the curved surface portion 11b. In this example, the magnetic force mounting portion 12 is designed to be provided on the surface of the flange 31a on which the web is not positioned. Further, since the load of the column product 3 is not applied to the plate member 12a, a relatively light aluminum plate is used.

Two shaft members 14 are provided on the plate member 12a at intervals in the horizontal direction. The shaft member 14 is inserted through a through hole formed in the buffer portion 11 , and the buffer portion 11 is supported by the magnetic force mounting portion 12 by the shaft member 14 .

Further, a plate member 13 is arranged facing the magnetic force mounting portion 12 so as to sandwich the buffer portion 11 , and the magnetic force mounting portion 12 and the plate member 13 are connected by the shaft member 14 . The upper side of the plate member 13 is located above the upper surface of the buffer portion 11, but the height of the plate member 13 is lowered so that the upper side of the plate member 13 does not contact the web of the flange 31a. The lower end of the plate member 13 is located above the lower surface of the buffer portion 11 and has a curved shape similar to that of the curved surface portion 11b.

Each shaft member 14 is composed of, for example, a bolt 14a and a nut 14b. Each bolt 14 a has a length exceeding the thickness of the buffer portion 11 . Each bolt 14a passes through a through hole formed in the plate member 13 from one surface side of the cushioning portion 11 and protrudes from a through hole formed in the plate member 12a. A nut 14b is screwed. When the bolt 14a is tightened, the plate member 13 and the plate member 12a press the buffer portion 11 from both sides, and the buffer portion 11 is held without backlash.

Further, since each shaft member 14 is composed of the bolt 14a and the nut 14b as described above, the buffer portion 11, the magnetic force mounting portion 12, and the plate member 13 can be separated.

With the above configuration, each corner portion 31b and the floor surface can be protected by the buffer portion 11 that receives the corner portion 31b at the end of the flange 31a, which is a magnetic plate portion. Since the state of being attached to the corner portion 31b is held by the magnetic force attachment portion 12, it is possible to eliminate the drawbacks of using a wooden crossbeam or a structural frame.

When the magnetic force mounting portion 12 is plate-shaped and is in surface contact with the flange 31a, the magnetic force holding the buffer portion 11 can be increased.

A shaft member 14 is provided on the plate-shaped magnetic force mounting portion 12, and when the buffer portion 11 is supported by the magnetic force mounting portion 12 by this shaft member, the buffer portion 11 and the magnetic force mounting portion 12 are separated. The cushioning portion 11 and the magnetic force mounting portion 12 can be integrated by the shaft member 14 without adhesion.

A plate member 13 is arranged to face the plate-shaped magnetic force mounting portion 12 so as to sandwich the buffer portion 11 , and the plate-shaped magnetic force mounting portion 12 and the plate member 13 are connected by the shaft member 14 . As a result, the buffer portion 11 is sandwiched between the magnetic force mounting portion 12 and the plate member 13 and stably supported.

If the buffer portion 11 and the magnetic force mounting portion 12 are provided separably, the buffer portion 11 and the like can be replaced when the buffer portion 11 and the like are damaged.

Further, if the portion of the cushioning portion 11 that receives the corner portion 31b has an inclined surface corresponding to the angle of the corner portion 31b, the contact area between the portion that receives the corner portion 31b and the corner portion 31b is reduced. It can be made as large as possible, and it is possible to prevent an excessive burden from occurring in one part.

In addition, in the above example, the magnetic force mounting portion 12 is formed in a plate shape, but the structure is not limited to this.

For example, in the corner pad 1A illustrated in FIG. has a concave portion 152a for receiving the corner portion 31b, and also serves as a magnetic force mounting portion by having a magnetic force. That is, the corner pad 1A is provided with a magnetic mounting portion on the inclined surface (the surface on which the load of the column product 3 is received) of the concave portion 152a that receives the corner portion 31b.

Further, in the corner pad 1B illustrated in FIG. 5, a cushioning portion 16 made of the same material as that of the cushioning portion 11 is formed with a concave portion 16a for receiving the corner portion 31b. The concave portion 16 a has walls 16 b made of the material of the buffer portion 16 on both sides in the thickness direction of the buffer portion 16 . The width of the concave portion 16a is such that the thickest flange 31a can be accommodated therein. A magnet sheet 17 is adhered to both wall portions 16b of the concave portion 16a. In this example, the magnet sheet 17 attached to both wall portions 16b of the concave portion 16a constitutes a magnetic force mounting portion. That is, the corner pad 1B is provided with a magnetic mounting portion made of the magnet sheet 17 on the wall portion 16b of the concave portion 16a which receives the corner portion 31b. The flange 31a is magnetically attracted to one of the two magnet sheets 17. As shown in FIG.

Further, the corner pad 1C illustrated in FIG. 6 includes a plate member (mounting portion) 18 in place of the plate-shaped magnetic force mounting portion 12 described above. The plate member 18 has a shape whose upper side widens at 90 degrees along the angle of the corner 31b of the flange 31a. The plate member (mounting portion) 18 is fixed to the flange 31a by a clip 19 to hold the cushioning portion 11 mounted on the corner portion 31b.

Although the embodiments of the present invention have been described above with reference to the drawings, the present invention is not limited to the illustrated embodiments. Various modifications and variations can be made to the illustrated embodiment within the same scope as the present invention or within an equivalent scope.
