That is, cargo can be handled such as scooping up, transporting, and moving up and down by inserting claws between the upper and lower horizontal rails of the wooden board.

JP 2002-347880 A

  However, the conventional packaging member always involves disposal at the time of unpacking, and consideration for the environment is the most important issue, but the actual situation in the field of product transportation tends to save labor on the cargo handling work. As the work is mechanized, the carrying member may be overstressed. For such packaging members, both environmental simplification and increased strength are required to avoid logistics problems. Yes.

  In general, the bottom of heavy cargo is provided with a packaging fixing stand, which is transported by a machine such as a forklift. The specifications of the thickness and width of the nail (fork), and the method for inserting the nail into the gap As a result, when a stress is applied that causes the nail of the joint portion to come off, the crosspieces come off, causing problems such as inability to transport the product.

  In addition, when joining wooden boards with nails, there is a large variation in strength depending on the type of wood, fiber, and moisture content, and not only the length and number of nails need to be increased in order to secure the prescribed strength, but also the nails. Since the joining force also varies depending on how you shoot, the width and thickness of the wooden board must be set large so that the gap between the nails is as much as possible, and the wood quality must be stabilized while selecting the material. The loss of material consumption until then was very large.

  For this reason, when changing from the joining with nails to the fastening method with bolts and nuts using washers, the problem of disconnection of the wooden board is improved, but the packaging fixing base has horizontal beams on the upper and lower surfaces of the wooden girders. If each joint is fastened with a sandwich structure with washers, bolts and nuts, the thickness of the parts is required as a space under the wooden board. Thus, the height of the packaging fixing base is increased by this dimension, and the volume and the packaging weight are increased, and the load handling property is deteriorated.

  SUMMARY OF THE INVENTION The present invention solves the above-described problem, and further provides a packaging member for a hot water storage water heater that simplifies the packaging member, solves the problems caused by the detachment of the horizontal rail, and eliminates wasteful consumption of materials. The purpose is to provide.

  In order to solve the above-described conventional problems, the packaging member of the hot water storage type hot water heater of the present invention includes a substantially rectangular parallelepiped exterior, a leg attached to a bottom plate of the exterior and having anchor bolt fixing holes, and a packaging for fixing the leg. The packaging fixing base is composed of a girder having a countersink hole on the lower surface, a horizontal beam arranged on the upper surface of the girder, and a thin plate stacked under the horizontal beam. Is arranged between the leg and the girder, the anchor bolt fixing hole to the countersink hole of the girder material are tightened with fastening bolts and nuts, and the thin plate is bent so as to be convex downward, The present invention is characterized in that a claw of a transport lift can be inserted into a gap formed between the horizontal rail and the thin plate.

  INDUSTRIAL APPLICABILITY The present invention can provide a packaging member for a hot water storage hot water heater that can further simplify the packaging member, eliminate problems caused by the horizontal rails being removed, and eliminate wasteful consumption of materials.

  The packaging member of the hot water storage type water heater of the first invention has a substantially rectangular parallelepiped exterior, a leg attached to a bottom plate of the exterior and having an anchor bolt fixing hole, and a packaging fixing base for fixing the leg. The fixed base is composed of a girder having countersink holes on the lower surface, a horizontal beam arranged on the upper surface of the girder, and a thin plate stacked under the horizontal beam. It is arranged between the anchor bolt fixing hole and the countersink hole of the girder with a fastening bolt and nut, and the thin plate is bent so as to be convex downward, between the crosspiece and the thin plate. The present invention is characterized in that the claw of the transport lift can be inserted into the formed gap.

  And by configuring in this way, the girder of the packaging fixing base and the crosspiece are fastened with a sandwich configuration with washers, bolts, nuts, so the type of wood, fiber, Variations in strength due to the amount of moisture are eliminated, strength stability can be secured, and problems due to horizontal runoff can be eliminated.

  Furthermore, it is possible to eliminate many losses caused by the consumption of a large amount of materials due to the selection of materials for increasing the width and thickness of the wooden board and stabilizing the wood.

  Furthermore, by changing the grounding surface, which was a horizontal rail on the lower surface, to a girder with countersink holes, it has been possible to simplify the structure in which the joints on both the upper and lower sides of the girder are concentrated only on the upper surface. it can. In addition, there has been a fall accident due to insufficient insertion of the nail because there was a bolt head that fixes the leg at the place where the nail of the transport lift of the horizontal rail on the upper surface is inserted conventionally. There is no need to provide a bolt in the claw insertion portion of the horizontal rail, and the claw insertion work is smoothed and the problem is solved. If the lift is suddenly started or stopped suddenly while the product is picked up by the nail, the product may fall from the nail, but the thin plate 14 is provided so as to hold the lower surface of the nail, preventing the fall. is doing.

  Furthermore, it is not necessary to provide a bolt in the nail insertion portion, and the problem caused by insufficient insertion of the nail is solved.

  Furthermore, when a product standing up due to the disappearance of the lower crosspiece is dropped, the upper crosspiece and girder material are easily deformed, so the impact on the ground contact surface of the leg can be reduced and the leg is supported. If the area of the countersink hole provided on the underside of the girder is made to be close to the ground contact area of the leg, the countersink will be easily deformed when the standing product is dropped, and the leg ground contact surface will be deformed. Such impact can be further mitigated.

  In addition, when a product horizontally stacked on a carrier platform is dragged down, a thin plate held at the bottom of the packaging fixing base is grasped and pulled, but this thin plate is bolted to the legs of the product body, the horizontal rail, and the girder. The nuts and the nuts are tightened together, and the possibility of hindering the work due to the failure of the side rails due to the omission of the nail is eliminated.

  Furthermore, the height of the packaging fixing base becomes lower than before by adopting a thin plate, and the packaging volume and the packaging weight can be reduced.

  Furthermore, in assembling the packaging fixing base, two types of work frames having a conventional cross-girder shape have been prepared, and two types of work for setting materials on them and joining them with nails have been required. . However, in the above invention, since a cross-beam shape is formed by stacking a convex thin plate on the bottom when setting the material, a work frame is not required and only the upper surface is joined, so that workability can be greatly improved.

  The packaging member of the hot water storage type hot water heater of the second invention has an opening in the side surface of the countersink hole, and the bolt can be inserted into the countersink hole from the opening in the first invention. Bolts and nuts can be attached and detached while standing tall vertical heavy-weight products such as hot water storage water heaters typified by water heaters, and the product packaging and unpacking operations become more efficient.

  The packaging member of the hot water storage type hot water heater of the third invention is a product that stands up by widening the outermost girders among the plural girders in the first or second invention. Even if an impact load is applied to the girders located on the outside of the packaging fixing base from slightly below when dropped, if the cross-section of the girders is widened, there will be no peeling moment at the joints between the legs and the crosspiece This makes it possible to realize a packaging fixing base that is difficult to be applied and not only ensures the strength of the packaging fixing base but also does not fall easily.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings. Note that the present invention is not limited to the embodiments.

(Embodiment 1)
FIG. 1 is a front structural perspective view of a hot water storage type water heater and a packaging member according to Embodiment 1 of the present invention, FIG. 2 is a front view of essential parts in Embodiment 1, and FIG. 3 is packaging fixing according to Embodiment 1. FIG. 4 is a perspective view of the structure of the pedestal, FIG. 4 is a view of the structure in the first embodiment when dropped, and FIG. Hereinafter, a description will be given with reference to FIGS.

  The present invention has a tank unit 1 having a substantially rectangular parallelepiped exterior having a hot water storage tank 5 inside, and a side plate 4 is fixed to a pipe connection plate 3 that is one step higher than the bottom plate 2. It has a rectangular parallelepiped exterior. A pipe connection port 6 that is an end of a pipe communicating with the hot water storage tank 5 is fixed to the pipe connection plate 3. In FIG. 1, the front plate that forms the front surface of the exterior is removed.

  The bottom plate 2 has a convex leg 9 having a hole 9-1 for fixing an anchor bolt, and supports the load of the tank 5 when the tank is full on the floor surface. The space from the floor surface to the pipe connection plate 3 is an indispensable work space for piping inspection when installing the tank unit 1 and for periodic inspections such as cleaning of functional parts and drainage when not in use for a long period of time. Therefore, a step between the bottom plate 2 and the pipe connection plate 3 is necessarily required.

  For this reason, the shape of the lower part of the side plate 4 has a step between the bottom plate 2 and the pipe connection plate 3 and is notched, so that stress is easily concentrated and deformed easily. The product in the finished packaging state is fixed on the packaging fixing base 7 with the bolt and nut 8 using the anchor bolt fixing hole 9-1 of the convex leg 9, and can be transported by a machine such as a forklift. It has a structure.

  Further, a packaging top cover 10 is covered on the top exterior, and a packaging support column 11 is provided on the vertical ridge line of the side plate 4 to reinforce the load from above. Moreover, the packaging support | pillar 11 has a L-shaped cross section, and is attached to the exterior by squaring, and is fixed to the product from the side by a band made of polypropylene.

  The hot water storage type hot water heater and its packaging member configured as described above can support the load on the stage even if the product is in a packaged state and stacked in a warehouse. It can be transported by grabbing 11 and pushed or dragged alternately left and right, or pulled down and stacked horizontally.

  Next, the configuration of the packaging fixing base 7 will be described. The packaging fixing base 7 has a two-layer structure of a girder 12 having a counterbore 12-1 on the lower surface and a horizontal beam 13 on the upper surface of the girder, and a horizontal beam bolt nut fixing portion 13 at both ends of each material. -1 is provided and assembled in a cross-beam shape. Moreover, it has the thin plate 14 closely_contact | adhered and piled up under the horizontal rail 13, is piled in order of the beam material 12, the thin plate 14, and the horizontal rail 13, and is fastened with the horizontal rail bolt nut fixing | fixed part 13-1. Further, the leg 9 of the product body is also fastened by the bolt and nut 8 from the counterbore 12-1 of the beam member 12 through the horizontal rail 13 and through the through hole.

  The thin plate 14 is made of a water-resistant material such as a resin plate, and is configured to be bent downward and have a gap parallel to the horizontal rail 13 so that a claw of a transportation lift can be inserted. In addition, the counterbore 12-1 has a slit hole from the side surface, and the bolt 8-1 can be inserted from the slit hole so that the bolt nut can be attached and detached even when the product is upright. Product packaging and unpacking operations are streamlined.

  Further, among the plurality of girders 12, the outermost girder 12 has a wider cross section, and even when an upright product is dropped, a moment to peel off the joint is unlikely to be applied. I have to.

  With the above configuration, the variation in strength due to the type of wood, fiber, and moisture content, which has been a problem in joining with conventional nails, can be eliminated, and the stability of strength can be ensured, and the problems due to side rail removal can be eliminated. Furthermore, it is possible to eliminate many losses caused by the consumption of a large amount of materials due to the selection of materials for increasing the width and thickness of the wooden board and stabilizing the wood.

Furthermore, in the past, the horizontal rail on the lower surface was grounded, but by changing the girder having the counterbore to ground, the joints on both the upper and lower sides of the girder 12 were concentrated only on the upper surface. Simple configuration was realized. In addition, since there was a bolt head for fixing the leg 9 at the position where the claw of the transport lift of the horizontal rail 13 on the upper surface was inserted, there was a fall accident due to insufficient insertion of the claw. There is no need to provide a bolt in the claw insertion portion of the crosspiece 13, so that the claw insertion operation is smoothed and the problem is solved. If the product is lifted or stopped suddenly with the nail being scooped up by the nail, the product may fall from the nail. However, the thin plate 14 is provided so as to hold the lower surface of the nail, preventing the fall. ing.

  As shown in FIG. 4, when the standing product is dropped, the upper crosspiece 13 and the beam member 12 are easily deformed, and not only can the impact on the ground contact surface of the leg 9 be reduced, but also the leg 9 is supported. If the area of the countersink hole 12-1 provided on the lower surface of the girder 12 is made larger than the ground contact area of the leg 9, the countersink 12-1 is likely to be deformed when dropped, further reducing the impact on the leg. .

  Further, when the product horizontally stacked on the carrier platform of the transport vehicle is pulled down as shown in FIG. 5, the thin plate 14 held at the bottom of the packaging fixing base 7 is grasped and pulled. It is necessary to add a new fastening as long as the material tensile strength of the thin plate 14 is secured with respect to the maximum momentary load when the product is shifted because the bolts and nuts 13-1 are fastened to the horizontal rail 13 to which the legs 9 are fixed. The work can be done without losing the same configuration.

  Further, the use of the thin plate 14 makes the height of the packaging fixing base 7 lower than before, and it is possible to reduce the packaging volume and the packaging weight.

  Furthermore, in assembling the packaging fixing base 7, conventionally, two types of work frames having a cross-girder shape have been prepared, and two types of work for setting materials and joining them with nails have been required for the upper surface and the lower surface. . However, in the above invention or the invention, since a cross-beam shape is formed by stacking a convex thin plate at the time of material setting, a work frame is not required and only the upper surface is joined, so that workability can be greatly improved.

  Furthermore, since the weight at the time of material disposal can be reduced and it can be easily disassembled, it can be said that the packaging member can contribute to environmental conservation.

  The girders 12 and the crosspieces 13 may be made of a material other than wood, that is, a resin or the like, and the material may have a hollow structure. As a result, the cross-section is easily elastically deformed, and this improves the shock-absorbing property, further reducing the impact on the product body and improving the impact resistance, as well as reducing the weight of the material. It is possible to achieve both environmental consideration and strength improvement as a member. Furthermore, if a material that can be recycled is used as a packaging material, it is even better in terms of environmental conservation.

  As described above, the packaging member of the hot water storage type hot water heater in the present embodiment can be used for an electric water heater having an electric heater inside as well as a heat pump type hot water heater using a heat pump as a heat source.
