Description

  The present invention is directed to stacking and transporting panel materials such as lightweight cellular concrete panels and various materials packed in a panel shape on a loading platform of a vehicle, and further supporting the substrate It is related with the conveyance method for collect | recovering.

  When transporting a plurality of panels having a standard size such as a lightweight aerated concrete (ALC) thin panel, a base plate is used mainly for protection from impact during transportation. This base plate usually uses an ALC thin panel having the same length and width, or a panel wider than the ALC thin panel, and a base made of wood or ALC is used under the base plate. It is a normal usage pattern.

  In addition, as a general method for transporting packages, for example, a platform (hereinafter referred to as “pallet”) on which packages are loaded is used in order to make handling work in factories, trucks, containers, warehouses, etc. easier to handle. There is a mode in which a forklift or a handlift claw is inserted into the hole-shaped portion of the pallet and lifted and loaded on a vehicle such as a truck, and the load and the pallet are conveyed as a package. Also in the case of an ALC thin panel conveyance form using this kind of conveyance form, it is usual to use a pallet having the same dimensions as the ALC thin panel or wider than the ALC thin panel.

  The ALC thin panel is transported to the construction site by the above transport modes. Since the ALC thin panel is appropriately used at the construction site, it is necessary to finally store it in a predetermined unloading area. Therefore, the transfer worker has been working to unload the ALC thin panel from the truck bed to the unloading area using a forklift or a triangular sling.

  In the conventional transport method, a plurality of transported objects are used by a base plate or a pallet (hereinafter collectively referred to as “base plate”) having the same size as the transport target such as an ALC thin panel or a size larger than the transport target. Supporting the body, it was difficult to handle the transported body and the base plate separately when unloading at the site. For this reason, it is normal for the transported object to be lowered from the loading platform and stacked in a predetermined unloading area while remaining on the mounting plate. In addition, there is room for improvement from the viewpoint of resource saving and energy saving because the base plate remaining on the site is difficult to reuse.

  The present invention aims to solve the above-described problems, and stacks and conveys a panel-shaped object to be transported on a base plate, and collects the base plate that supported the object to be transported after reaching the destination. It is an object of the present invention to provide a method for transporting a panel-shaped transported body that can be easily performed.

According to a first method of the present invention, a pair of bar-shaped pedestal members are installed on a cargo bed at a distance from each other so as to stack and convey panel-shaped objects to be conveyed on a cargo bed of a vehicle. In addition, a base plate that is narrower than the transported body is installed, and both side ends of the transported body protrude from the base plate, and the transported body is stacked and placed on the base plate. The transported body is transported to the destination by moving the transported body away from the bed so that both side edges of the transported body are lifted, the transported body is lowered from the loading platform, and the base plate left on the loading platform It is characterized by collect | recovering .

In the present invention, the base plate is narrower than the transported body, and the transported body is stacked on the base plate so that both side ends protrude from the base plate. Therefore, when the transported body is unloaded from the loading platform after arriving at the destination, the transported body can be easily separated from the base plate by lifting the side edge of the transported body using, for example, a triangular sling. Ru can be. As a result of that, it can be easily recovered the base plate. Furthermore, according to the present invention, since the base plate is installed on the pair of rod-like base members installed on the cargo bed, even if the base plate is left on the cargo bed, the base member It is also easy to insert a claw such as a forklift into the gap between them and lower the base plate from the cargo bed to collect it.

According to a second method of the present invention, a pair of bar-shaped pedestal members are installed on a cargo bed at a distance from each other so as to stack and convey panel-shaped objects to be conveyed on a cargo bed of a vehicle. In addition, a base plate that is narrower than the transported body is installed, and both side ends of the transported body protrude from the base plate, and the transported body is stacked and placed on the base plate. The transported body is transported to the destination by the above, the transported body is lowered from the loading bed together with the base plate, the transported body is separated from the base plate so as to lift the side end of the transported body, and the base plate is collected. It is characterized by that.
In the present invention, the base plate is narrower than the transported body, and the transported body is stacked on the base plate so that both side ends protrude from the base plate. Therefore, even when the transported body is lowered from the loading platform together with the base plate, even after the transported body is lowered to a predetermined place because both side edges are projected from the base plate, It can be easily separated from the base plate by lifting only the conveyed object. As a result, the base plate can be easily collected.

According to a third method of the present invention, there is provided a transport method for stacking and transporting a panel-shaped object to be transported on a loading platform of a vehicle, wherein a pair of rod-shaped seating members are installed on the loading platform with a gap therebetween, After installing a base plate that is narrower than the transported body and placing the transported bodies stacked on the base plate so that both side edges of the transported body protrude from the base plate The transported body is transported to the destination by the vehicle, and a pair of rod-shaped mounts are arranged in the unloading area of the destination side by side with an interval that can contact both side ends of the transported body. The height of the base plate is larger than the thickness of the base plate. At the destination, the transported body is lowered from the loading platform by the lifting and lowering transport device while being placed on the base plate, and the base plate is placed between the pair of bases. Lower the base plate so that it fits and hand over the transported object to the pair of mounts. Characterized in that it is pulled came to recover the base plate. Even when a plurality of transported bodies are unloaded from the loading platform using a lifting / lowering transport device such as a forklift, the transported bodies are unloaded on a pair of mounts arranged in the unloading area. Thus, the transported body is transferred to the pair of mounts, and as a result, the base plate is separated from the transported body between the pair of mounts. And a base plate can be easily collect | recovered by pulling out the base plate spaced apart from the to-be-conveyed body.

  Preferred embodiments of the present invention will be described below with reference to the drawings. This embodiment demonstrates in the aspect which conveys the lightweight cellular concrete panel (Autoclaved Light-weight Concrete) (henceforth "ALC thin panel") P as a to-be-conveyed body. The ALC thin panel P (see FIG. 1) is mass-produced with standardized standard dimensions at a predetermined factory, and loaded on a loading platform 1a of a vehicle 1 such as a truck to a storage location (destination) such as a construction site or a warehouse. Are transported. For example, the ALC thin panel P transported to the construction site is unloaded and appropriately stacked, and sequentially built into a predetermined position of the reinforced concrete (Reinforced-Concrete) structure to construct the wall structure of the building To be used.

  A procedure for loading the ALC thin panel P on the vehicle 1 will be described with reference to FIGS. 1 and 2. Two (a pair) pedestal members 3 are installed on the loading platform 1a of the vehicle 1 at a predetermined interval (see FIG. 2A). The material of the pedestal member 3 is a rod-shaped member having a rectangular cross section made of wood, resin, or lightweight cellular concrete, and the longitudinal direction of the pair of pedestal members 3 is directed in a direction (left-right direction) orthogonal to the front-rear direction of the vehicle 1. It has been.

  Next, a base plate 5 made of a lightweight cellular concrete made of the same material as the ALC thin panel P is installed on the base member 3 (see FIG. 2B), and a plurality of ALC thin plates are placed on the base plate 5. A panel block B is constructed by stacking the shaped panels P. The ALC thin panel P is a rectangular panel having a pair of long sides Pa and a pair of short sides Pb. The base plate 5 is a rectangular panel having a short side 5b having the same dimension as the short side Pb of the ALC thin panel P and a long side 5a having a shorter dimension than the long side Pa of the ALC thin panel P. In the present embodiment, the width of the ALC thin panel P or the base plate 5 means the length on the long side Pa, 1a side. Therefore, the base plate 5 is a rectangular panel having a narrower width than the ALC thin panel P.

  The ALC thin panel P is placed so as to overlap the base plate 5, but both side edges in the direction along the long side Pa (width direction) of the ALC thin panel P (hereinafter referred to as “short side portion”). Pc is stacked so as to project from the side edge of the base plate 5 in the width direction.

  On the loading platform 1a of the vehicle 1, for example, the panel blocks B are stacked in two upper and lower stages. In this embodiment, a total of six panel blocks B are loaded on the loading platform 1a. A pair of pedestal members 3 made of lightweight cellular concrete are installed on the lower panel block B. On the pedestal member 3, an upper panel block B is placed. The six panel blocks B are fixed to the loading platform 1a by two wires 1c. A protective material (not shown) is disposed on the upper edge of the panel block B in order to suppress damage due to interference with the wire 1c.

When the vehicle 1 is transported, an impact force proportional to the weight of the panel block B is applied, but the panel block B is supported by the base plate 5 and the base plate 5 is supported by the pair of base members 3. Damage to the block B is prevented and the panel block B is transported safely.
(First base plate collection method)

  Next, with reference to FIG.3 and FIG.4, the 1st base plate collection | recovery method of the ALC thin panel P is demonstrated. In the first base plate collection method, an unstable place where the roadbed surface is not leveled, for example, the construction site A1 is assumed as the destination. In the construction site A1, since the roadbed surface is not leveled, an elevating and conveying device such as a forklift cannot be used. Therefore, when it arrives at the construction site A1, the unloading work is performed using the triangular sling 7.

  Here, the triangular sling 7 will be described in detail. Triangular sling (see, for example, “Gikendo Publishing Co., Ltd.“ Architecture Glossary (2nd edition) ”) 7 is composed of a substantially triangular steel receiving material 7a and wire 7b, and lifts ALC thin panel P and the like. It is a jig used to do. The steel receiving member 7a has an approximate length of about 60 cm, and a hole connected to the hook C at the tip of the crane is provided in the substantially central portion of the steel receiving member 7a, that is, the central portion including the vicinity of the top of the triangle. Yes. The upper ends of the two wires 7b are connected and fixed to the left and right ends of the steel receiving material 7a. Of the total four wires 7b, the two left and right wires 7b are paired, and the lower ends of each of the pair of wires 7b are fixed to the left and right ends of one equilateral angle steel 7c. In other words, the four wires 7b are in pairs and support a total of two equilateral angle steels 7c.

  The plurality of ALC thin panels P stacked on the loading platform 1a as the panel block B are brought out of the base plate 5, that is, the short side portion (side edge) Pc of the ALC thin panel P is the base plate. 5 is overhanging in the width direction. The two equilateral angle steels 7c are installed in inscribed alignment with both short side portions Pc of the ALC thin panel P, and then lifted by the unit of the panel block B through the triangular sling 7 by the crane (FIG. 4). reference). At this time, both the short side portions Pc of the ALC thin panel P and the steel receiving material 7a are balanced so as to form a triangular shape with the wire 7b. By unloading in this way, it is possible to unload the panel block B from the loading platform 1a so that the panel block B is separated from the base plate 5, and place it in a predetermined unloading area. As a result, only the base plate 5 and the base member 3 can be left on the loading platform 1 a of the vehicle 1.

  A gap S is formed by a pair of base members 3 between the base plate 5 and the loading platform 1a. By inserting a claw such as a forklift into the gap S, the base plate 5 can be easily recovered, and the remaining base member 3 can also be easily recovered. As a result, it is easy to return the base plate 5 and the base member 3 to a factory or the like for reuse, which contributes to the realization of resource saving, energy saving and economical transportation.

  Advantages of the transport method employing the first base plate collection method will be described in comparison with the conventional transport method. In the conventional transport method, the panel or pallet used as the base plate is the same size as the ALC thin panel or larger than the ALC thin panel, so the base plate and the ALC thin panel are handled separately. It was very difficult. Therefore, it is necessary to unload the base plate and the ALC thin panel on the base plate, and the collection of the base plate is performed after all the ALC thin panels on the base plate are used for construction. I couldn't do it without it. For this reason, it is usually discarded as industrial waste together with ALC thin panel scraps generated at the construction site, which is not economical because it is not resource-saving and the disposal cost is high.

  In particular, when using a pallet as a base plate, a wooden pallet is often used, but it may decay in a wet environment, and must be disposed of as industrial waste when uncollected or damaged. . On the other hand, plastic pallets made of resin (polypropylene, polyethylene, etc.) are superior in strength and load-bearing capacity compared to wooden pallets and are less damaged, but are difficult to regenerate when damaged, resulting in industrial disposal. It must be discarded as waste. Also, metal pallets made of iron or aluminum are expensive, and paper pallets made of cardboard are very low in strength and are operated on the premise of being disposable, so they are not resource-saving.

  According to the transport method of the panel-shaped transported body according to the present embodiment, safe transport on the strength of the panel block B and unloading with the panel block B and the base plate 5 separated can be performed. Moreover, by unloading using the triangular sling 7, for example, it is possible to unload at a place where the roadbed surface is unstable, and further, from the loading platform 1a while leaving the base plate 5 on the loading platform 1a. Since only the panel block B can be easily unloaded, the base plate 5 remaining on the loading platform 1a can be easily collected. Accordingly, it is possible to prepare a physical distribution environment in which the base plate 5 supporting the ALC thin panel P during transportation can be efficiently circulated between the factory and the construction site A1, thereby enabling resource-saving, energy-saving and economical transportation. become.

  Moreover, in this embodiment, since the base plate 5 which consists of a lightweight aerated concrete panel is employ | adopted, defective products, such as an edge part chipping | deterioration which generate | occur | produces during manufacture of the ALC thin panel P as a product, are cut and used, for example. It can also be produced resource-saving and economically. Furthermore, it is effective in reducing industrial waste generated in the factory.

In addition, in the case of the base plate 5 made of a lightweight cellular concrete panel, it is relatively fragile and plastic, so when it is subjected to a large impact, it can be visually observed as a defect, so that it can be easily judged whether it can be reused or operated safely. Can do.
(Second base plate collection method)

  Next, with reference to FIG.5 and FIG.6, the 2nd base plate collection | recovery method of the ALC thin panel P is demonstrated. In the second base plate collection method, a stable place where the roadbed surface is leveled, for example, warehouse A2 is assumed as the destination. When arriving at the warehouse A2, the forklift 9 as the lifting and lowering conveying device is brought close to the vehicle 1, the claw 9a of the forklift 9 is inserted into the gap S formed by the base member 3, the panel block B is lifted together with the base plate 5, and the loading platform Remove from 1a.

  In the unloading area Aa of the warehouse A2, two (a pair of) mounts 11 are arranged in advance so as to be substantially parallel with a predetermined interval L2. The material of the gantry 11 is a rod-shaped member having a rectangular cross section made of wood, resin, or lightweight cellular concrete, and the height H when installed on the ground surface is higher than the plate thickness 5 h of the base plate 5. Dimensional shape.

  Further, the predetermined interval L2 is a distance that is longer than the length L1 of the long side 5a of the base plate 5 and shorter than the length L3 of the long side Pa of the ALC thin panel P. The interval L2 is an interval at which each of the mounts 11 can come into contact with the short side portion (side end) Pc of the ALC thin panel P at the lowermost stage of the panel block B. Specifically, if the width of the base plate 5 is L1, and the width of the ALC thin panel P is L3, the dimension relationship is always L1 <L2, and the distance L2 between the bases 11 is L1 <L2 <L3. Arrange so that Further, when the difference between L3 and L1 is da, the cross-sectional dimension of the gantry 11 is assumed to be smaller than da / 2.

  The forklift 9 lowers the panel block B and the base plate 5 so that the base plate 5 fits between the pair of mounts 11 (see FIG. 6A). And after passing the panel block B to a pair of mounts 11 (refer FIG.6 (b)), the baseplate 5 is pulled out and collect | recovered between a pair of mounts 11 (refer FIG.6 (c)), and only for baseplates To the storage location.

  Thereafter, the claw 9a of the forklift 9 is inserted into the gap S2 obtained by the gantry 11, and only the panel block B is transferred and stacked in a predetermined storage location. At the time of loading, another gantry 11 can be used.

  In the transport method adopting the second base plate collection method, it is possible to safely transport the panel block B in strength, and the panel block B together with the base plate 5 is unloaded from the bed 1a to the unloading area Aa. When placing, the base plate 5 can be easily separated and collected. Therefore, it is possible to prepare a physical distribution environment in which the base plate 5 supporting the ALC thin panel P during the transportation can be efficiently circulated between the factory and the warehouse A2, thereby enabling resource-saving, energy-saving and economical transportation. Become.

  In addition, since the base plate 5 is arranged at the lowest stage so as to support the panel block B, an accident that destroys the ALC thin panel P as a product with the claws 9a of the forklift 9 at the time of unloading is minimized. Can be suppressed.

  By using this transport method, for example, only the base plate 5 can be easily collected at a stable place such as the warehouse A2 with a well-organized management system, and further, it can be transferred to a storage place dedicated to the base plate and stored. Therefore, when returning the base plate 5, for example, the base plate 5 is accumulated until it reaches an economical quantity for transportation, and when the predetermined amount is accumulated, it is returned to a factory or the like for reuse. System management becomes easy, contributing to the realization of resource saving, energy saving and economical transportation methods. Alternatively, the base plate 5 temporarily placed in a storage location dedicated to the base plate can be loaded and returned to the loading platform 1a of the vehicle 1 as it is.

  In this embodiment, the gantry 11 is arranged so as to avoid the descending base plate 5. However, in consideration of the movement after using the forklift 9 in the warehouse A2, a panel block together with the base plate 5 is provided. If the bases 11 are arranged and unloaded so that B can be supported, it is also possible to leave the base plate 5 as it is for protection. Further, in this case, the base plate 5 with the base 11 in which the base 11 of any material is fixed to the lower side of the base plate 5 in advance using an adhesive or a screw may be used. In the first base plate recovery method described above, the case where the ALC thin panel P is directly sent from the factory to the construction site A1 and unloaded by the triangular sling 7 has been described. However, the forklift 9 unloads the warehouse A2. After that, it is transported from the warehouse A2 to the construction site A1 and unloaded by the triangular sling 7. At that time, the base plate 5 can be separated and recovered.

  The present invention is not limited to the above embodiment. For example, the transported body is not limited to an ALC thin panel, and may be other panels or various materials in which members of panel materials are packed. .
