Description

[0001]
[Field of the Invention]
The present invention relates to a rack provided with a horizontal barrier material and a method for attaching the horizontal barrier material to the rack.
[0002]
[Prior art]
In a rack used for an automatic warehouse or the like, a horizontal barrier material for preventing the spread of fire is arranged for each predetermined number of stages. In this case, the rack columns are connected to each other by a horizontal connecting material such as a round pipe for every predetermined number of stages, and a plate-like horizontal barrier material is attached to the horizontal connecting material to separate the racks every predetermined number of stages. For example, a sprinkler head is provided below the horizontal barrier material.
[0003]
Since the horizontal connecting material is a round pipe, it is difficult to install a horizontal barrier material by making a screw hole or the like in the pipe. Therefore, for example, the end portion of the horizontal barrier material is processed into a C shape or the like, and the C portion is fitted and attached to the horizontal connecting material. However, if it does in this way, the cost of a horizontal barrier material will increase and construction will also be difficult.
[0004]
[Problems of the Invention]
A basic object of the present invention is to facilitate the attachment of a horizontal barrier material to a horizontal connecting material of a rack (claims 1 to 4).
An additional problem in the invention of claim 2 is to use an inexpensive corrugated sheet for the horizontal barrier material, and to facilitate the connection between the horizontal barrier materials in the middle of the front of the rack.
An additional problem in the invention of claim 3 is that a horizontal barrier material such as a corrugated plate can be easily pressed down from above with a fixture.
[0005]
[Structure of the invention]
The present invention is a rack in which a horizontal connecting material is passed between columns for each predetermined stage, and a plate-like horizontal barrier material is attached on the horizontal connecting material to prevent the spread of fire, and the horizontal connecting material is placed on the lower side. The horizontal barrier member is horizontally connected using a fitting integrally provided with a main body portion held from the upper end of the main body portion and a pair of pressing portions that extend from both upper ends of the main body portion and press the end portion of the horizontal barrier material from above. It is attached to the material (Claim 1).
[0006]
Preferably, the horizontal barrier material is formed of corrugated plates, the ends of the two horizontal barrier materials are overlapped between the rack columns and the column, and the holding portion of the fixture is used as two horizontal barriers. While sandwiching between the materials, the ends of the two horizontal barrier materials are fixed to each other (Claim 2).
Preferably, the pressing portion of the fixture is curved and thinner than the main body (Claim 3).
[0007]
The method of attaching the horizontal barrier material to the rack of the present invention is as follows: when attaching the plate-like horizontal barrier material for preventing fire spread on the horizontal binder material of the rack in which the horizontal binder material is passed between the columns for each predetermined stage. Using a fixture provided integrally with a main body part that holds the horizontal binder from the lower side and a pair of pressing parts that extend from both upper ends of the main body part and press the end part of the horizontal barrier material from the upper side, The horizontal tie material is held by the main body portion of the fixture, and the end portion of the horizontal barrier material is pressed by the pressing portion (claim 4).
[0008]
[Operation and effect of the invention]
In the rack according to the present invention, the horizontal barrier material can be used as the horizontal binder by holding the horizontal binder from the lower side in the main body of the fixture and pressing the end of the horizontal barrier material by the pressing portion at the tip of the fixture. Can be attached. For this reason, it is unnecessary to fix the screws to the horizontal connecting material, and the horizontal barrier material can be easily attached to the horizontal connecting material such as a round pipe.
[0009]
In this invention, since it is not necessary to fit the horizontal barrier material to the horizontal connecting material, an inexpensive and high strength corrugated sheet can be used for the horizontal barrier material. Here, even if the width of the frontage of the rack is varied, the type of horizontal barrier material is not increased. For example, two horizontal barrier materials are assigned to one frontage, and the horizontal barrier material is overlapped at the center of the frontage. It is easy to adjust the length. Therefore, it is easy to use a fixture on the part where the two horizontal barrier materials are overlapped, and sandwich the holding part of the fixture between the overlapped horizontal barrier materials, and fix the horizontal barrier material to each other at the overlapped part. Two horizontal barrier members can be attached to the horizontal connecting member at the center of the frontage or the like (claim 2).
[0010]
If the holding part of the fixture is curved and is made thinner than the main body, it will be easier to hold down the horizontal barrier material such as corrugated plate from the top, and it will be deformed according to the curvature of the end of the corrugated sheet. (Claim 3).
[0011]
In the method of attaching the horizontal barrier material according to the present invention, the horizontal barrier material can be attached to the rack by holding the horizontal binder material by the main body of the fixture and pressing the end of the horizontal barrier material by the holding portion. The horizontal barrier material can be easily attached (Claim 4).

【Example】
1 to 5 show an embodiment. In these drawings, reference numeral 2 denotes a rack, which is used, for example, in an automatic warehouse, and a traveling path 4 of a stacker crane is provided on one side thereof so that articles can be loaded and unloaded. Reference numerals 6 to 9 are rack columns, columns 6 and 8 are columns on the side facing the traveling path 4, and numerals 7 and 9 are columns on the opposite side of the traveling path. In the embodiment, the sizes of the support columns 6 and 7 and the support columns 8 and 9 are changed. Reference numerals 10 and 11 denote horizontal barrier materials, for example, using inexpensive corrugated sheets, and here, corrugated sheets of galvanized steel sheets. Two horizontal barrier materials 10 and 11 are used for one frontage, and the horizontal barrier materials 10 and 11 are overlapped at the center of the frontage. Here, the horizontal barrier material 10 is made to overlap the horizontal barrier material 11. Reference numerals 12 and 13 are flat plates, which are made of galvanized steel plates and used to block gaps between the horizontal barrier members 10 and 11 in the vicinity of the columns 6 and 9.
[0013]
14 and 15 are, for example, round pipe-like horizontal connecting members, which are attached to the support columns 6 and 9 via brackets (not shown), and the horizontal connecting member 14 is on the side of the traveling path 4 of the stacker crane, and the horizontal connecting member 15 is the opposite. It is arranged on the side. Reference numeral 16 denotes a square pipe that connects the left and right sides (front side and back side) of the rack 2. Reference numeral 18 denotes a sprinkler head disposed in the gap between the flat plates 13. In the rack 2, the horizontal barrier materials 10 and 11 provided for each predetermined number of stages prevent the spread of fire, and the sprinkler head 18 is disposed below the horizontal barrier materials 10 and 11. A fire extinguisher is provided to extinguish the fire.
[0014]
Reference numerals 20 and 21 denote attachment tools, each of which includes a main body portion that holds the horizontal connecting members 14 and 15 from the lower side, and a pressing portion that extends to the upper portion of the main body portion and is sandwiched between the horizontal barrier materials 10 and 11. The edge part of the center of the front of the barrier member 10 is fixed to the horizontal connecting members 14 and 15 side. The main purpose of providing the attachments 20 and 21 is to prevent the horizontal barrier members 10 and 11 from rolling up and hindering transfer by a stacker crane fork or the like. There is no need to provide the fixture 21 on the side of the horizontal connecting material 15 that does not contact the stacker crane.
[0015]
Reference numerals 22 and 23 denote screws, which may be other fixing means such as bolts and adhesives. The screws 22 attach the flat plates 12 and 13 to the square pipe 16, and the screws 23 attach the horizontal barrier members 10 and 11 to the flat plates 12 and 13. They are attached to the lower side and fixed to each other at the portion where the horizontal barrier materials 10, 11 are overlapped. Here, the reason why the two horizontal barrier members 10 and 11 are used at one front end of the rack 2 is to allow the common horizontal barrier material to cope with various front end widths. Can be dealt with by changing the width of the portion where the horizontal barrier materials 10, 11 are overlapped.
[0016]
FIG. 2 shows the height level of the rack 2 around the horizontal barrier materials 10 and 11. The horizontal barrier members 10 and 11 are on a horizontal connecting member 14 and the like, and a shelf holder 30 is arranged on the upper side thereof and fixed to the column 6 and the like. The space between the shelf holder 30 and the horizontal barrier material is an operation space such as a slide fork of a stacker crane, and the position where the slide fork is lowered most is indicated by a line P1 in FIG. In addition, a lower-stage baggage is placed on the lower side of the horizontal connecting material 14 and the upper limit height thereof is indicated by a line P2 in FIG. Since the rack 2 gives priority to accommodation efficiency, it is necessary to reduce the gap between the horizontal barrier members 10 and 11 and the shelf holder 30 and also to reduce the gap between the horizontal connecting member 14 and the upper limit height of the luggage. There is. Therefore, when the horizontal barrier materials 10 and 11 are rolled up, transfer by a slide fork or the like is hindered.
[0017]
3 and 4 show the configuration of the fixture 20. The structure of the attachment 21 is the same as that of the attachment 20. The fixture 20 includes a semicircular or loop-shaped main body portion 32 that holds the horizontal connecting member 14, and a pressing portion 34 that extends from the upper side of the main body portion and is curved in a wave shape and is thinner than the main body portion 32. ing. A pair of pressing portions 34 exist on both upper sides of the main body portion 32, are parallel to each other, and extend in a direction perpendicular to the surface formed by the main body portion 32. Here, the pressing portion 34 is curved in a wave shape in order to match the curvature of the corrugated plate of the horizontal barrier materials 10 and 11, and the thinner than the main body portion 32 is the overlapping of the horizontal barrier materials 10 and 11. This is to make the gap in the height direction of the portion as small as possible. The attachment 20 is made of steel, for example.
[0018]
As shown in FIGS. 3 and 4, the main body portion 32 holds the horizontal connecting member 14 from the lower side, and the holding portion 34 is sandwiched between portions where the end portions of the horizontal barrier members 10 and 11 are overlapped. The horizontal barrier material 10 is pressed from above. The horizontal barrier members 10 and 11 are connected to each other by screws 23 or the like at the overlapped portions. If a suitable tool is used, the screw 23 can be easily attached without opening a screw hole in advance. Further, since the role of the screw 23 is to connect the horizontal barrier members 10 and 11 to each other, the screw 23 may be sandwiched and stopped by a pin 36 shown in FIG.
[0019]
FIG. 5 shows attachment of the flat plate 12 and the like to the square pipe 16. The flat plate 12 or the like is attached to the square pipe 16 using a screw 22 or the like, and the ends of the horizontal barrier materials 10 and 11 are attached to the flat plate 12 or the like using a screw 23 or the like. Since it is a square pipe, screwing the flat plate 12 is easy.
[0020]
The attachment method of the horizontal barrier materials 10 and 11 in an Example is demonstrated. The skeleton structure of the rack 2 such as the columns 6 to 9, the square pipe 16, and the horizontal connecting members 14 and 15 is completed. Next, the horizontal barrier members 10 and 11 are temporarily placed, the fixtures 20 and 21 are set on the horizontal connecting members 14 and 15, and are sandwiched between the horizontal barrier members 10 and 11 on which the pressing portions are overlapped.
[0021]
Thereafter, if the screws 22 and 23 are sequentially attached with an appropriate tool, the attachment of the flat plates 12 and 13 and the horizontal barrier members 10 and 11 is completed. Since the horizontal barrier materials 10 and 11 are corrugated plates, they are inexpensive and strong, and there is no particular difficulty in mounting, unlike the case where screw holes are formed in the horizontal connecting materials 14 and 15 made of round pipes. That is, the attachment can be performed by setting the attachments 20 and 21 and attaching the screws 22 and 23.
[0022]
In the embodiment, since the left and right sides of the rack 2 are connected by the square pipe 16, the flat plates 12 and 13 can be easily attached to the square pipe 16 with screws 22 or the like. When a round pipe or the like is used instead of the square pipe 16, it is difficult to fix the screw. Therefore, it is preferable to use the attachment of the embodiment with a slight deformation even in this portion. In this case, for example, the fixture 20 shown in FIGS. 3 and 4 is slightly deformed so that the pressing portion 34 protrudes in the opposite direction to the left and right outsides in the same plane as the main body portion 32. Then, the holding portion may be sandwiched between the flat plates 12 and 13 and the horizontal barrier materials 10 and 11, and the horizontal barrier materials 10 and 11 and the flat plates 12 and 13 may be fixed with screws 23. In this way, the fixture sandwiched between the horizontal barrier members 10 and 11 and the flat plates 12 and 13 holds the round pipe from below, so that it can be fixed without screws.
