Description

[Technical field]

[0001] The present invention relates to a loading rack and a construction method using the loading rack, and more particularly to a loading rack capable of being transported while being loaded with building materials, and a construction method using the loading rack. [Background technology]

[0002] 2. Description of the Related Art Loading racks capable of loading building panels and wooden construction members manufactured in a factory for transporting these building panels and construction members are known (see, for example, Patent Documents 1 and 2). To explain the specific loading and transportation methods, first, the building panels and construction materials removed from the factory production line are stored in the factory in a flat-stacked state on a loading rack. At this time, the construction materials are often collected on pallets and stacked flat while being secured with bands or the like. After that, they are loaded in this flat-stacked state onto the loading rack by truck or the like and transported to the construction site. The transported building panels and construction materials are unloaded by a tow truck or forklift installed at the construction site and stored at the construction site. The loading rack may be returned to the factory or may be used on-site as a storage rack as in Patent Document 2. [Prior art documents] [Patent documents]

[0003] [Patent Document 1] JP 2016-89567 A [Patent Document 2] JP 2020-105770 A Summary of the Invention [Problem to be solved by the invention]

[0004] Incidentally, in the loading racks as disclosed in Patent Documents 1 and 2, there has been a demand for a loading rack capable of loading construction members more stably. For example, when unloading a loading rack loaded with construction materials at a construction site, there has been a demand for the loading rack to be able to be unloaded more stably. There was also a demand for a loading rack that could be assembled more easily than before.

[0005] The present invention has been made in consideration of the above problems, and an object of the present invention is to provide a loading rack that is capable of loading construction components more stably than conventional loading racks. Another object of the present invention is to provide a loading rack that can be assembled more easily than conventional racks. [Means for solving the problem]

[0006] The above problem is solved by the loading rack of the present invention, which is a loading rack that can be transported while loaded with building materials, comprising a frame-shaped base member that serves as the base of the loading rack, and a support member that is spanned across the base member and on which the building materials are placed, the base member having a pair of first base members extending in one of the length and width directions of the loading rack, and a pair of second base members extending in the other of the length and width directions, the support members having mounting portions formed on both ends of the support member in the extension direction and that can be detachably attached to the first base member in the horizontal direction, and when the support member is attached to the pair of first base members, the mounting portions clamp the first base member in the vertical direction. With the above configuration, it is possible to realize a loading rack that can load construction materials more stably than before. More specifically, in the loading rack of the present invention, the receiving member has mounting parts formed on both ends in the extending direction thereof, and is detachably attached to the first base member in the horizontal direction. When the receiving member is attached to the pair of first base members, the mounting parts sandwich the first base members in the vertical direction. Therefore, the receiving member is suitably assembled to the base members, and can stably support the building members. Furthermore, since the receiving member is detachably attached to the first base member in the horizontal direction, the receiving member can be easily attached to and detached from the first base member.

[0007] In this case, the pair of first base members extend in the length direction of the loading rack, the pair of second base members extend in the width direction of the loading rack, the support member is an intermediate support member extending in the width direction of the loading rack, spanned across the pair of first base members, and positioned between the pair of second base members, and the mounting portion preferably has an abutment wall portion that abuts against a side of the first base member, and an upper wall portion and a bottom wall portion that respectively protrude from the abutment wall portion at a distance in the vertical direction and sandwich the first base member in the vertical direction. As described above, the mounting portion has the contact wall portion that contacts the side surface of the first base member, and the top wall portion and the bottom wall portion that sandwich the first base member in the up-down direction. Therefore, for example, the receiving member can be suitably assembled to the first base member without requiring a fastening bolt.

[0008] In this case, the receiving member has a fixing portion provided on a side surface of the mounting portion and fixed to a fixed portion provided on a side surface of the first base member, one of the fixing portion and the fixed portion being a fixing convex portion that protrudes toward the other of the fixing portion and the fixed portion, and the other of the fixing portion and the fixed portion being a fixing hole portion that is removably fixed to the fixing convex portion, and the receiving member is attached to the first base member in a state in which its movement is restricted in the vertical and horizontal directions. With the above-mentioned configuration, the receiving member is attached to the first base member in a state where its movement in the vertical and horizontal directions is restricted. Therefore, the receiving member can more stably support the building component. In addition, the receiving member can be suitably assembled to the first base member without requiring a fastening bolt.

[0009] In this case, it is preferable that the receiving member is removably attached to the pair of first base members in a horizontal direction, and the pair of second base members is removably attached to the pair of first base members in a direction intersecting the attachment direction of the receiving member. With the above-mentioned configuration, the pair of first base members, the pair of second base members and the receiving member can be assembled more firmly, so that the building members can be stably loaded.

[0010] Furthermore, the above problem is solved by a construction method using a loading rack of the present invention, which includes a rack assembly process of assembling the loading rack, a loading process of loading the building materials onto the assembled loading rack, a transporting process of transporting the loading rack with the building materials loaded thereon, and an unloading process of unloading the loading rack, in which in the rack assembly process, the pair of first base members are arranged at a predetermined interval, the support member is attached to the pair of first base members from a horizontal direction, and the pair of second base members are attached to the pair of first base members connected by the support member from a direction intersecting the attachment direction of the support member. The above configuration makes it possible to realize a construction method using a loading rack that can load building materials more stably than conventional methods.

[0011] At this time, in the transporting step or the unloading step, the forks of a forklift are inserted from an end of the loading rack in the longitudinal direction, and the receiving member of the loading rack is held from below by the forks. With the above configuration, by using the receiving members fixed in the vertical direction, it is possible to insert a forklift (forks) even from the end (short side) in the length direction of the loading rack and transport the loading rack. Therefore, even if it is not possible to insert a forklift (forks) from the end (long side) in the width direction of the loading rack for transportation due to the size or shape of the truck bed or the site restrictions at the construction site, it is possible to flexibly respond to the situation. Effect of the Invention

[0012] According to the loading rack and the construction method using the loading rack of the present invention, it is possible to load construction materials more stably than before. Also, the loading rack can be assembled more easily than before. [Brief description of the drawings]

[0014] Hereinafter, an embodiment of the present invention will be described with reference to FIGS. This embodiment relates to a "loading rack" that can be transported while loaded with building materials and that allows building materials to be loaded more stably than in the past. Specifically, this embodiment relates to a "loading rack" that allows building materials to be loaded stably by firmly assembling the components (base member, receiving member) of the loading rack together. It also relates to an invention for an "construction method using a loading rack."

[0015] 1, the loading rack 1 of this embodiment is a rack capable of transporting a plurality of plate-shaped building components 2 loaded thereon. For example, the loading rack 1 is used to stack the building components 2 flat in a factory and transport the building components 2 in a stacked state from the factory to a construction site by truck. The loading rack 1 is also called a procurement logistics rack, a transport rack (current delivery rack), a storage rack (wood rack), etc. depending on the purpose of use. The loading rack 1 may be used commonly for each purpose, or may be used specifically for each purpose.

[0016] The building components 2 are plate-like components used in various buildings, and include building panels such as exterior wall panels, roof panels, and waist-high wall panels, as well as wooden construction components, etc. The building components 2 are also called current deliveries. When architectural panels are loaded as the building components 2, they are placed vertically at a specified interval so as not to damage the finishing surface material, and when wooden construction components are loaded, they are stacked on a pallet and secured to the pallet with bands or the like.

[0017] As shown in FIG. 1, the loading rack 1 comprises a frame-shaped base member (a pair of first base members 10 and a pair of second base members 20), a plurality of pillar members 30 arranged at the four corners of the base members and extending upward from the first base members 10, an intermediate support member 40 spanning the pair of first base members 10, a pair of connecting members 50 extending in the longitudinal direction of the loading rack 1 to connect the pillar members 30, and a pair of second support members 60 extending in the width direction of the loading rack 1 to connect the pillar members 30. The above-mentioned "frame-shaped base member" corresponds to the pair of first base members 10 and the pair of second base members 20. The intermediate support member 40 is also bridged across the pair of connecting members 50. The mounting positions and the number of the pillar members 30, the intermediate support members 40, the connecting members 50, and the second support members 60 can be changed as appropriate. For example, they can be changed according to the load of the construction members 2.

[0018] <First base member, second base member> As shown in Figures 1 to 6, the first base member 10 and the second base member 20 are members that form the foundation of the loading rack 1 and are made of, for example, long bodies processed from square pipes made of metal material. They ensure the rigidity of the loading rack 1 and also function as supporting members for placing the building members 2 on their upper surfaces. The first base member 10 extends longitudinally in the lengthwise direction of the loading rack 1, and connects the pillar members 30 to each other. The second base member 20 extends elongatedly in the width direction of the loading rack 1, and connects the first base members 10 to each other.

[0019] The first base member 10 includes a base body 11 and legs 15 attached to both ends of the base body 11 in the longitudinal direction and extending downward from the base body 11. The base body 11 serves as a receiving portion for the construction member 2. The legs 15 are supporting legs that support the column members 30 from below, and are attached to the outer surfaces of the base body 11 in the width direction.

[0020] At both ends of the base body 11, base engagement holes 12 are formed for horizontally and detachably engaging the second base member 20 (engagement protrusions 23). Fixing holes 13 (fixed portions) for fixing the intermediate receiving member 40 (fixing protrusions 43) are formed at intervals on the side surface of the base body 11. In addition, sling hook portions 14 for hooking a sling of a lifting device are formed at intervals on the bottom surface of the base body 11.

[0021] The upper end (upper portion) of the leg 15 is formed with a pillar engagement recess 16 (pillar engagement portion) for detachably engaging the pillar member 30 (engagement protrusion 32) in the vertical direction, and a slit-shaped support groove 17 for inserting the support protrusion 33 therethrough. The column engagement recess 16 has a closed cross-sectional (rectangular cross-sectional) structure. The support groove 17 is a groove formed on the inner surface of the column engagement recess 16 and extends in the vertical direction.

[0022] As shown in FIG. 4, a key groove 18 is formed at the upper end of the boundary between the base engagement hole 12 and the pillar engagement recess 16, straddling the base engagement hole 12 and the pillar engagement recess 16. The key groove 18 is a slit-like groove into which the convex lock member 34 of the pillar member 30 is fitted.

[0023] The second base member 20 comprises a second base main body 21, extension portions 22 attached to the side surfaces of both longitudinal ends of the second base main body 21 and extending outward in the longitudinal direction, engagement protrusions 23 (engaged portions) formed on the extended ends of the pair of extension portions 22 and engaging with the first base member 10 (base engagement hole portion 12), and a second key groove 24 formed on the side portion (outer portion) of the engagement protrusion 23.

[0024] The second base body 21 serves as a receiving portion for the construction member 2. The extension portion 22 is attached to the outer surface of the second base body 21 so as to avoid interference with the building member 2, and is disposed so as not to protrude upward beyond the second base body 21. The engagement protrusion 23 protrudes laterally from the extension 22 and is adapted to be detachably engaged with the base engagement hole 12 from the horizontal direction. Specifically, the engagement protrusion 23 has a U-shaped cross section and has a main body wall portion 23a protruding from the extension portion 22 toward the first base member 10, and a pair of reinforcing wall portions 23b extending from both widthwise ends of the main body wall portion 23a. The second key groove 24 is a slit-like groove into which the lock member 34 of the pillar member 30 is fitted.

[0025] In the above configuration, when assembling the loading rack 1, a pair of first base members 10 are first arranged with a predetermined distance between them as shown in Figures 2 and 3. Then, an intermediate support member 40 is attached to the pair of first base members 10 from the horizontal direction. Then, a pair of second base members 20 are attached to the pair of first base members 10 connected by the intermediate support member 40 from a direction intersecting (perpendicular to) the attachment direction of the intermediate support member 40.

[0026] <Column member 30> As shown in Figures 1 and 3 to 6, the pillar members 30 are members that serve as supports for the loading rack 1, and are made of, for example, long bodies processed from square pipes, and are arranged at the four corners of the loading rack 1, making a total of four. Specifically, the pillar member 30 comprises a pillar main body 31 having a rectangular cross section that is elongated in the vertical direction, an engagement protrusion 32 formed at the lower end of the pillar main body 31 and engaging with the first base member 10 (pillar engagement recess 16), a support protrusion 33 and a locking member 34 protruding from the inner surface of the pillar main body 31, and a clamping portion 35 protruding from the outer surface of the pillar main body 31. As shown in FIG. 9, the pillar member 30 is provided in the upper portion of the pillar main body 31, protrudes from the side of the pillar main body 31 in opposite directions, and has an engagement hole portion 36 and a second engagement hole portion 37 that engage with the connecting member 50 (engagement protrusion 52) or the second receiving member 60 (second engagement protrusion 63).

[0027] As shown in FIGS. 4 and 5, the engaging protrusion 32 has a closed cross section. The support projection 33 projects from the inner surface of the engaging protrusion 32 and extends in the vertical direction. The pillar member 30 is assembled to the first base member 10 (leg portion 15) in the up-down direction by fitting the engaging protrusion 32 into the pillar engaging recess 16. At this time, the support protrusion 33 is inserted into the support groove 17 and held by the support groove 17. This makes it easier to position the column member 30 when assembling the column member 30 to the first base member 10. In addition, the assembly rigidity can be increased.

[0028] As shown in Figures 4 and 5, the locking member 34 is a convex-shaped member that protrudes from the inner surface of the engaging protrusion 32, is formed adjacent to the support protrusion 33, and protrudes outward beyond the support protrusion 33. The locking member 34 fits into both the overlapping key groove 18 and the second key groove 24 to engage and lock the first base member 10, the second base member 20, and the pillar member 30 together.

[0029] As shown in FIGS. 5 and 6, the clamping portion 35 is a bent clamping member protruding from the outer surface of the engaging protrusion 32, and is formed on the opposite side to the supporting projection 33 and the locking member . The clamping portion 35 can clamp the pillar engaging recess 16 of the first base member 10 between the clamping portion 35 and the engaging protrusion 32. Therefore, the pillar member 30 can be assembled to the first base member 10 in a stable manner.

[0030] 9, the fitting hole 36 and the second fitting hole 37 are formed at predetermined intervals in the vertical direction and have a common fitting method. The fitting hole 36 (second fitting hole 37) is also called a fitting pocket. The fitting hole 36 is disposed on the inner surface of the pole member 30 in the longitudinal direction of the loading rack 1, and the second fitting hole 37 is disposed on the outer surface of the pole member 30. The fitting hole 36 fits with the connecting member 50 (fitting protrusion 52), and the second fitting hole 37 fits with the second receiving member 60 (second fitting protrusion 63), but is not particularly limited thereto. For example, the fitting hole 36 may fit with the second fitting protrusion 63, and the second fitting hole 37 may fit with the fitting protrusion 52.

[0031] The fitting hole portion 36 has a pair of side wall portions 36a that protrude outward from the inner surface of the pillar member 30 with a gap therebetween in the width direction of the pillar member 30, and a connecting wall portion 36b that connects the protruding ends of the pair of side wall portions 36a. Similarly, the second fitting hole 37 has a pair of side walls 37a and a connecting wall 37b.

[0032] In the above configuration, as shown in Figures 4 and 5, when the second base member 20 (engagement protrusion 23) is horizontally engaged with the first base member 10 (base engagement hole portion 12) and the pillar member 30 (engagement convex portion 32) engages with the first base member 10 (pillar engagement recess 16) from above, the locking member 34 of the pillar member 30 locks (engages and locks) the first base member 10, the second base member 20, and the pillar member 30 together. Specifically, the key groove 18 of the first base member 10 and the second key groove 24 of the second base member 20 are arranged to overlap, and the locking member 34 fits into both the key groove 18 and the second key groove 24. In this way, the first base member 10, the second base member 20, and the pillar member 30 are locked together.

[0033] <Intermediate support member> As shown in Figures 1, 2, 7, and 8, the intermediate support member 40 is a member that is spanned between a pair of first base members 10 or a pair of connecting members 50, and is made of a long body, for example, a processed square pipe, and functions as a support member on which the building member 2 is placed. The intermediate receiving member 40 is disposed between a pair of second base members 20 or between a pair of second receiving members 60 . Specifically, the intermediate support member 40 comprises a support body 41 that is elongated in the width direction of the loading rack 1, mounting portions 42 formed on both ends of the support body 41 in the longitudinal direction and that clamp (hold) the base body 11 (connecting body 51), and a fixing convex portion 43 (fixing portion) provided on the side of the mounting portion 42 and protruding from the side of the mounting portion 42 toward the side of the base body 11 (connecting body 51).

[0034] The mounting portion 42 is detachably attached to the base body 11 (connecting body 51) in the horizontal direction, and clamps the base body 11 so as to surround it. Specifically, the mounting portion 42 has a contact wall portion 42a that contacts the inner surface of the base body 11, and an upper wall portion 42b and a bottom wall portion 42c that protrude from the contact wall portion 42a at a distance in the vertical direction and sandwich the base body 11 in the vertical direction. The mounting portion 42 is attached to the first base member 10 so as to surround the base body 11 on three sides by the contact wall portion 42a, the upper wall portion 42b, and the bottom wall portion 42c.

[0035] The fixing protrusion 43 is a fixing pin that protrudes laterally from the outer surface of the abutting wall portion 42 a, and is detachably fixed to a fixing hole portion 13 provided on the inner surface of the base body 11. The fixing protrusion 43 is formed so as not to protrude outward beyond the upper wall portion 42b and the bottom wall portion 42c. This makes it easier to assemble the intermediate support member 40 to the first base member 10. Specifically, first, the vertical position of the intermediate support member 40 is determined relative to the first base member 10, and the first base member 10 is sandwiched between the upper wall portion 42b and the bottom wall portion 42c. Thereafter, the horizontal position of the intermediate support member 40 relative to the first base member 10 is determined, and the fixing protrusion 43 is inserted into the first base member 10 (fixing hole portion 13). For example, by going through such a procedure, it becomes easier to assemble the intermediate support member 40 to the first base member 10.

[0036] 7 and 8, the intermediate support member 40 has an attachment portion 42 and a fixing protrusion 43. Therefore, the assembly rigidity of the loading rack 1 can be increased while eliminating the need for bolt fastening.

[0037] 7 and 8, the intermediate support member 40 has attachment portions 42 (upper wall portion 42b and bottom wall portion 42c). Therefore, the intermediate support member 40 is attached to the first base member 10 in a state in which its movement in the up-down direction is restricted. Moreover, the intermediate receiving member 40 has a fixing protrusion 43. Therefore, the intermediate receiving member 40 is attached to the first base member 10 in a state in which its movement in the horizontal direction is restricted. This allows the intermediate support member 40 to be assembled easily and firmly.

[0038] 8, in the intermediate receiving member 40, a step 44 is formed at a connecting portion between the receiving body 41 and the mounting portion 42. In other words, the contact wall portion 42a is formed so as to protrude slightly in the vertical and horizontal directions beyond the receiving body 41. Therefore, the construction component 2 can be suitably placed on the upper surface of the intermediate support member 40. That is, the step 44 can be utilized to suppress positional deviation (lateral deviation) of the construction component 2.

[0039] 2 and 3, in the above configuration, the intermediate support member 40 is detachably attached to the pair of first base members 10 in a horizontal direction. The pair of second base members 20 are detachably attached to the pair of first base members 10 in a direction intersecting the attachment direction of the intermediate support member 40. This makes it possible to more firmly assemble the pair of first base members 10, the pair of second base members 20, and the intermediate support member 40. As a result, the construction members 2 can be stably loaded.

[0040] <Connecting member, second receiving member> The connecting members 50, as shown in FIGS. 1 and 9, are members that connect the pillar members 30 that are aligned in the longitudinal direction of the loading rack 1, and function as members that impart rigidity to the loading rack 1. Specifically, the connecting member 50 has a long connecting body 51 and mating protrusions 52 formed on both ends of the connecting body 51 in the longitudinal direction and mating with the pillar member 30 (fitting hole portion 36). The fitting protrusion 52 is attached to an end surface in the longitudinal direction of the connecting body 51, protrudes downward from the connecting body 51, and detachably fits from above into the fitting hole 36. In other words, the fitting protrusion 52 fits into the fitting hole 36 by a wedge method.

[0041] In the above configuration, as shown in FIG. 9, when the connecting member 50 is assembled to the pillar member 30, the end (end face) of the mating protrusion 52 abuts against the side face of the pillar member 30, and the mating protrusion 52 is fitted into the mating hole portion 36. This eliminates the need for bolt fastening and increases the assembly rigidity of the loading rack 1.

[0042] As shown in Figures 1 and 9, the second support member 60 is a member that connects the column members 30 lined up in the width direction of the loading rack 1, and in addition to imparting rigidity to the loading rack 1, it also functions as a support member on which the building members 2 are placed. Specifically, the second receiving member 60 has a long receiving body 61, extension portions 62 attached to the side surfaces of both longitudinal ends of the receiving body 61 and extending outward in the longitudinal direction, and second mating protrusions 63 formed on the extending ends of the pair of extension portions 62 and adapted to fit into the pillar member 30 (second mating hole portions 37). The second fitting protrusion 63 fits into the second fitting hole 37 by a wedge method.

[0043] In the above configuration, as shown in FIG. 9, when the second receiving member 60 is assembled to the pillar member 30, the end (end face) in the longitudinal direction of the receiving body 61 abuts against the side surface of the pillar member 30, the extension portion 62 abuts against the outer surface of the pillar member 30, and the second fitting protrusion 63 is fitted into the second fitting hole portion 37. This eliminates the need for bolt fastening and increases the assembly rigidity of the loading rack 1.

[0044] With the above configuration, it is possible to realize the loading rack 1 that can load construction materials more stably than ever before. Also, it is possible to realize the loading rack 1 that can be easily assembled. In particular, by providing the intermediate support member 40 as described above, the intermediate support member 40 can be easily assembled to the base members 10, 20, and can be firmly attached.

[0045] <Installation method using a loading rack> Next, a construction method using the loading rack 1 will be described. This construction method includes at least the following steps: (1) a rack assembly process; (2) a loading process; (3) a transport process; and (4) an unloading process. The steps are described in detail below. In addition, explanations of construction steps other than those mentioned above regarding the construction of the building foundation will be omitted.

[0046] (1) In the "rack assembling process", a worker assembles the loading rack 1 as shown in Figs. 2 to 9. Specifically, as shown in Fig. 2, a worker first arranges a pair of first base members 10 with a predetermined distance between them, and attaches an intermediate support member 40 to the pair of first base members 10 in the horizontal direction. Then, as shown in Fig. 3, a pair of second base members 20 are attached to the pair of first base members 10 connected by the intermediate support member 40 in a direction intersecting the attachment direction of the intermediate support member 40. Then, as shown in Figs. 4 to 6 and 9, a worker attaches the pillar members 30, the connecting members 50, and the second support members 60 to assemble the loading rack 1.

[0047] (2) In the “loading process”, a worker loads construction components 2 onto the assembled loading rack 1. When building panels are loaded, they are placed vertically at a certain distance apart so as not to damage the finishing surface material. When wooden construction materials are loaded, they are stacked on pallets.

[0048] (3) In the "transportation process", a worker transports the loading rack 1 with the construction components 2 loaded thereon. Specifically, the loading rack 1 on which the construction members 2 are stacked is loaded onto a transport vehicle such as a truck, and the construction members are transported from the factory to the construction site by the truck. (4) In the "unloading process", a worker unloads the loading rack 1 from a transport vehicle such as a truck. In the above (3) "Transportation Process" and / or (4) "Unloading Process", as shown in FIG. 10, a worker inserts the forks F1 of the forklift F from the longitudinal end (short side) of the loading rack 1 and holds (grabs) the intermediate support member 40 and the second support member 60 of the loading rack 1 with the forks F1. In this way, by using the firmly assembled intermediate support member 40, the forklift F (forks F1) can be inserted even from the end (short side) in the length direction of the loading rack 1 to transport the loading rack 1. Therefore, even if the forklift F (forks F1) cannot be inserted and transported from the end (long side) in the width direction of the loading rack 1 due to the size or shape of the truck bed or the site restrictions at the construction site, it is possible to flexibly respond to the situation. The worker may insert the forks F1 from the ends (long sides) in the width direction of the loading rack 1 and hold the pair of first base members 10 of the loading rack 1 as in the normal case.

[0049] <Other embodiments> In the above embodiment, as shown in FIG. 1, the loading rack 1 is composed of two first base members 10, two second base members 20, four pillar members 30, four intermediate support members 40, two connecting members 50, and two second support members 60, but the number of each component part is not particularly limited and can be changed. For example, as long as the rigidity of the loading rack 1 can be ensured, the number of intermediate support members 40, connecting members 50, or second support members 60 may be reduced. Alternatively, in order to increase the rigidity of the loading rack 1 and to suitably load the construction members 2, the number of the pillar members 30, the intermediate support members 40, the connecting members 50, and the second support members 60 may be increased. Alternatively, the height of the loading rack 1 may be increased by arranging and connecting the pillar members 30 in the vertical direction. In that case, it is preferable to prepare pillar members 30 of different heights.

[0050] In the above embodiment, as shown in FIG. 1, the intermediate support member 40 is spanned across a pair of first base members 10 (a pair of connecting members 50), but this is not particularly limited and the intermediate support member 40 may be spanned across a pair of second base members 20 or a pair of second support members 60.

[0051] In the above embodiment, the intermediate support member 40 may have a mechanism that allows it to expand and contract in the extending direction. In that case, the assembly method of the loading rack 1 is not limited to the method shown in Figures 2 and 3. For example, it is also possible to assemble the pair of first base members 10 and the pair of second base members 20 first, and then assemble the intermediate support member 40.

[0052] In the above embodiment, the loading rack and the construction method using the loading rack according to the present invention have been mainly described. However, the above embodiment is merely an example for facilitating understanding of the present invention, and is not intended to limit the present invention. The present invention can be modified or improved without departing from the spirit of the present invention, and the present invention naturally includes equivalents thereof. In particular, the above-described embodiment is merely an example and does not limit the present invention. [Explanation of symbols]
