Description

  The present invention relates to a rack having a plurality of vertical and horizontal shelves for storing articles, and more particularly to a rack having a horizontal barrier that suppresses the spread of fire upward when a fire occurs.

  Racks used in automatic warehouses and the like increase storage efficiency by allowing a plurality of articles to be stored in the height direction. In such an automatic warehouse, in order to suppress the upward expansion of the fire that has occurred inside, the rack is obliged to install a horizontal barrier that divides the articles stored in a plurality of stages in the vertical direction. For example, it is obliged to provide a horizontal barrier every 4 meters or less.

Therefore, conventionally, an attachment method for attaching the horizontal barrier on-site has been proposed (for example, see Patent Document 1). In the rack of Patent Document 1, as shown in FIG. 7, a horizontal barrier 1004 is installed between a horizontal connecting material 1002 that connects the left and right support columns 1001 and a flat plate 1003. The flat plate 1003 and the horizontal barrier 1004 are fixed by a horizontal connecting material 1002 and a screw 1005.
Japanese Patent No. 3997831

  However, in the conventional rack, it is necessary to screw the horizontal barrier and the horizontal connecting material. That is, the operator needs to accurately align the flat hole, the horizontal barrier, and the screw holes of the horizontal connecting material at the site where the rack is installed. That is, it is difficult and time-consuming to attach the horizontal barrier to the rack at the construction site. As a result, there is a problem that the load of workers on the construction site increases.

  Therefore, the present invention has been made in view of the above problems, and it is an object of the present invention to facilitate the attachment of a horizontal barrier to a rack at a construction site and reduce the work load.

  In order to achieve the above object, a rack according to the present invention includes a pair of front and rear columns that are erected in the left-right direction, and a plate-shaped horizontal barrier that partitions a storage space surrounded by the columns at a predetermined height. A long upper wall portion, a long lower wall portion disposed so that the upper wall portion and the wall surface face each other, and the lengths of the upper wall portion and the lower wall portion Side walls connecting one side of the direction to each other, and adjacent to each other in the left-right direction so that the opening sides of the groove portions formed by the respective wall surfaces of the upper wall portion, the lower wall portion, and the side wall portions face each other. A rod-shaped back surface that is installed at substantially the same height of the columns and connects the pair of guide rails spanned between the pair of front and rear columns and the plurality of columns erected at the rear of the rack. Breath and fixed to the column, the back The horizontal barrier is fixed to the rack by inserting each of the opposing sides into the groove of the pair of guide rails, and the gusset plate includes: It is provided in the position which plugs up the back end face of the guide rail.

  Accordingly, the horizontal barrier can be fixed to the rack by inserting the horizontal barrier along the guide rail. That is, since it is not necessary to fix the horizontal barrier using a screw or the like, the installation work by the worker at the construction site is facilitated. As a result, it is possible to reduce the time required for installation by the operator and reduce the work load.

  In addition, since the rear end face of the guide rail can be closed using a gusset plate provided in a general rack, it is possible to restrict the backward movement of the horizontal barrier inserted in the guide rail. That is, it becomes possible to restrict the movement of the horizontal barrier in the rear direction without requiring new members or special processing.

  The pair of guide rails are provided in plural at substantially the same height of a pair of front and rear columns that are erected in the left-right direction, and the rack further includes the pair of front and rear columns and left and right side surfaces of the columns. It is preferable that the plate material is provided so as to close a horizontal plane surrounded by the two guide rails provided at substantially the same height, and the plate material is fixedly provided on the upper surface of the guide rail. .

  Thereby, since it becomes possible to block the horizontal cross section which cannot be blocked by the horizontal barrier, it is possible to increase the effect of suppressing the spread of fire upward when a fire occurs.

  According to the present invention, in a rack having a horizontal barrier that suppresses the spread of fire upward when a fire occurs, it is possible to facilitate the installation work of the horizontal barrier and reduce the work load on the construction site.

  Hereinafter, a rack according to an embodiment of the present invention will be described with reference to the drawings.

  FIG. 1 is a perspective view of a rack 100 according to an embodiment of the present invention when viewed from the right rear side. Here, the left-right direction of the rack is the X-axis, the front-rear direction is the Y-axis, and the up-down direction is the Z-axis. The same applies to the following drawings.

  As shown in FIG. 1, the rack 100 stores a plurality of articles 200 vertically and horizontally. The article 200 stored in the rack 100 is taken in and out from the front surface of the rack 100 using, for example, a stacker crane 300 or the like.

  The rack 100 also includes a support column 101, a horizontal connecting member 102, a back brace 103, a shelf holder 104, and a horizontal barrier 105.

  The support columns 101 are a pair of front and rear pipe members each having a rectangular cross section that is erected in the left-right direction (X-axis direction). The plurality of support columns 101 are connected to each other by a horizontal connecting member 102, a back face brace 103, and the like.

  The horizontal connecting member 102 is a rod-shaped member having a round cross section that connects adjacent struts 101 at a predetermined height. The horizontal binder 102 connects the front columns 101 or the rear columns 101 to increase the strength of the rack 100.

  The rear face brace 103 is a rod-shaped member that couples different struts 101 at different heights to the rear struts 101 of the rack 100. As shown in the figure, the corresponding two back braces 103 are installed so as to intersect in an X shape. The back brace 103 increases the strength of the rack 100.

  The shelf receiver 104 is a pair of left and right members that are installed across a pair of front and rear columns for each predetermined height. The article 200 is placed on each of the pair of shelf supports 104 such that a part of the lower surface is in contact therewith. By installing a plurality of such shelf receivers 104 in the height direction (Z-axis direction), it is possible to store a plurality of articles 200 in the rack 100.

  Further, the shelf receiver 104 is installed so that a fork or the like of the stacker crane 300 can be inserted under the article 200 even when the article 200 is placed. Accordingly, the article 200 placed at the intermediate position can be taken in and out without moving the article 200 placed up and down.

  The horizontal barrier 105 is a plate-like member installed near the upper side of the horizontal connecting material 102. Further, the horizontal barrier 105 is made of a non-flammable or flame retardant material that can withstand heat during a fire. Specifically, the horizontal barrier 105 is an inexpensive galvanized corrugated steel sheet.

  The horizontal barrier 105 divides the storage space surrounded by the four columns 101 up and down. That is, the horizontal barrier 105 blocks the fire generated below the rack 100 from spreading upward, and suppresses the spread of fire to the article 200 or the like stored above.

  A sprinkler (not shown) that discharges water when a predetermined temperature is exceeded is installed below the horizontal barrier 105. Due to the synergistic effect of the sprinkler and the horizontal barrier 105, the rack 100 suppresses the upward expansion of the fire.

  Next, the structure around the horizontal barrier 105 will be described in more detail with reference to FIGS.

  FIG. 2 is an enlarged front view of the rack 100 according to the embodiment of the present invention. FIG. 3 is a cross-sectional view (A-A cross-sectional view shown in FIG. 2) of the rack 100 according to the embodiment of the present invention.

  As shown in FIGS. 2 and 3, the guide rail 106 is a member having a “U” cross section. Further, the guide rails 106 are installed at substantially the same height of the columns 101 adjacent in the left-right direction so that the opening sides of the “U” shape face each other.

  Further, the guide rail 106 is installed across the front and rear columns 101. The guide rail 106 and the front and rear columns 101 are joined by welding or the like at a factory, for example.

  The horizontal barrier 105 is held by inserting the left and right sides into the guide rail 106 thus installed.

  The gusset plate 107 shown in FIG. 2 is a plate-like member that fixes the support column 101 and the back face brace 103 erected on the rear side. The gusset plate is provided at a position that covers the rear end surface of the guide rail 106.

  The flat plate 108 shown in FIG. 3 is installed so as to block a horizontal plane surrounded by the pair of front and rear support columns 101 and two guide rails 106 installed at substantially the same height on the left and right side surfaces of the support columns 101. Is a plate material. The flat plate 108 and the two guide rails 106 are joined by welding or the like at a factory, for example.

  As described above, the support columns 101 erected in the front-rear direction are connected via the guide rail 106. That is, the guide rail 106 increases the strength of the rack 100 in addition to fixing the horizontal barrier 105 to the rack 100. As a result, for example, the rack 100 can reduce other members for increasing the strength.

  Furthermore, since the guide rail 106 can be joined to the support column 101 at the factory, the work load on the construction site can be reduced.

  Further, since the gusset plate 107 is installed in the rack 100 so as to block the rear end face of the guide rail 106, the horizontal barrier 105 inserted into the guide rail 106 is restricted from moving backward. In other words, the rack 100 can regulate the backward movement of the horizontal barrier 105 using the gusset plate 107 installed in a general rack without the need for new members or special processing. it can.

  Further, the flat plate 108 is installed at a position that closes an area surrounded by the support column 101 and the guide rail 106. That is, since it becomes possible to block a horizontal section that cannot be blocked by the horizontal barrier, it is possible to increase the ability to suppress upward fire spread when a fire occurs.

  Next, details of the guide rail 106 will be described with reference to FIG.

  FIG. 4 is a perspective view of the guide rail 106 provided in the rack 100 according to the embodiment of the present invention.

  As shown in FIG. 4, the guide rail 106 includes an upper wall portion 106a, a lower wall portion 106b, a side wall portion 106c, and a groove portion 106d.

  The upper wall portion 106a and the lower wall portion 106b are long plate-like members. And it arrange | positions so that the wall surface of the upper wall part 106a and the wall surface of the lower wall part 106b may oppose.

  The side wall part 106c is a member that connects one side in the longitudinal direction of the upper wall part 106a and the lower wall part 106b. That is, the guide rail 106 is a member in which the upper wall portion 106a, the lower wall portion 106b, and the side wall portion 106c are integrally molded in a U shape.

  The groove part 106d is a recessed part surrounded by the respective wall surfaces of the upper wall part 106a, the lower wall part 106b, and the side wall part 106c.

  The horizontal barrier 105 inserted into the groove portion 106d is restricted from moving in the vertical direction by the upper wall portion 106a and the lower wall portion 106b, and is restricted from moving in the left-right direction by the side wall portion 106c. That is, the horizontal barrier 105 is fixed to the rack 100 by the guide rail 106.

  Next, details of the horizontal barrier 105 will be described with reference to FIG.

  FIG. 5 is a perspective view of the horizontal barrier 105 provided in the rack 100 according to the embodiment of the present invention.

  As shown in FIG. 5, the horizontal barrier 105 is a rectangular corrugated plate member. Specifically, for example, an inexpensive galvanized steel sheet. Further, the horizontal barrier 105 is installed so that the direction in which the peaks and valleys formed on the corrugated plate extend and the longitudinal direction of the guide rail 106 are orthogonal to each other.

  As described above, when the horizontal barrier 105 is a corrugated plate and is installed in the above-described direction, the strength of the horizontal barrier 105 is increased. That is, it is possible to suppress the deformation of the horizontal barrier 105 due to the rising airflow at the time of a fire, and to suppress the expansion of the fire from below to above.

  Finally, an operation for attaching the horizontal barrier 105 will be described with reference to FIG.

  FIG. 6 is a view for explaining the mounting operation of the horizontal barrier 105 to the rack 100 according to the embodiment of the present invention.

  As shown in FIG. 6, the operator inserts the left and right sides of the horizontal barrier 105 into the left and right grooves 106 d from the front end surface of the guide rail 106. Then, the horizontal barrier 105 is fed back along the guide rail 106 (in the direction of the arrow shown in the drawing) until it contacts the gusset plate 107 that closes the rear end surface of the guide rail 106.

  In this way, when the insertion of the horizontal barrier 105 into the guide rail 106 is completed, the operator closes the front end surface of the guide rail 106 in order to restrict the horizontal barrier 105 from moving forward. For example, the operator closes the opening on the front end surface by sandwiching the upper wall portion 106a and the lower wall portion 106b of the guide rail 106 with pliers or the like. Further, the operator may close the opening of the front end surface or fix the corrugated plate with screws, bolts, or the like.

  As described above, at the installation site of the rack 100, an operator can fix the horizontal barrier 105 to the rack 100 only by inserting the horizontal barrier 105 along the guide rail 106. That is, the operator can easily attach the horizontal barrier 105 to the rack 100 without performing difficult work such as positioning for screwing.

  Although the rack of the present invention has been described based on the embodiments, the present invention is not limited to the above embodiments. Unless it deviates from the meaning of this invention, what made the said embodiment various deformation | transformation which those skilled in the art think is also included in the scope of the present invention.

  For example, in the rack 100 according to the embodiment of the present invention, the guide rail 106 has a letter “U” in cross section, but may have a letter “U”. Moreover, although the side wall part 106c has connected the upper wall part 106a and the lower wall part 106b over the whole surface of the longitudinal direction, you may make it connect a part. That is, the guide rail 106 may be anything as long as it can guide the horizontal barrier 105 from the front to the rear when attached and can fix the horizontal barrier 105 after installation.

  Further, in the rack 100 according to the embodiment of the present invention, the gusset plate 107 covers the rear end surface of the guide rail 106. However, for example, even if the stored article and the wire mesh that prevents the fall prevent the rear end surface of the guide rail 106 from closing. Good.

  Further, when the horizontal cross section of the space surrounded by the front, rear, left and right columns 101 is larger than the area of one horizontal barrier 105, two or more horizontal barriers 105 may be inserted into the guide rail 106. . In this case, the operator inserts the horizontal barrier 105 into the guide rail 106 by overlapping a part of the two horizontal barriers 105 with each other.

  Even in the case where it is necessary to block one cross section with such a plurality of horizontal barriers 105, the operator can insert the horizontal barrier 105 along the guide rail 106 relatively easily. It can be attached to the rack 100.

  Further, the horizontal barrier 105 may not be a corrugated plate. In other words, the horizontal barrier 105 may be anything as long as the function of partitioning the upper and lower sides is not lost due to heat and rising airflow in the event of a fire.

  The rack according to the present invention can be used as, for example, a high-rise rack used in an automatic warehouse, as a rack having a horizontal barrier that suppresses the spread of fire upward when a fire occurs.
