Description

Technical Field

[0001] The present invention relates to a loading rack, and particularly to a loading rack for transporting and storing building members in a loaded state.

Background Art

[0002] Conventionally, in order to transport building panels and wooden construction members manufactured in a factory, a loading rack capable of loading these building panels and construction members is known (see, for example, Patent Documents 1 and 2). Regarding the specific loading and transportation method, first, building panels and construction members taken out from the manufacturing line of the factory are stored in the factory in a state of being stacked flat on the loading rack. At this time, the construction members are often stacked on a pallet and stacked flat in a state fixed with a band or the like. Then, they are loaded as they are stacked flat on the loading rack by a truck or the like and transported to the construction site. The transported building panels and construction members are unloaded by a wrecker, a forklift, or the like installed at the construction site and stored at the construction site. The loading rack can be used at the site as a storage rack by providing a roof member as in Patent Document 2.

Summary of the Invention

Problems to be Solved by the Invention

[0004] Incidentally, while a loading rack like the one in Patent Document 2 can be used to transport building panels and wooden construction materials from the factory to the construction site and store them there, there was still room for further improvement. For example, there was a need for a loading rack that could be assembled more easily than conventional racks. Or, there was a need for a loading rack that could stably assemble roof components by modifying the components of the roof components.

[0005] The objective of the present invention is to provide a loading rack that can be assembled more easily than conventional racks. Another object of the present invention is to provide a loading rack that allows for the stable assembly of roof components. [Means for solving the problem]

[0006] The aforementioned problems are solved by the present invention, which provides a loading rack for transporting and storing building materials in a loaded state, comprising: a plurality of column members arranged at at least four corners of the loading rack and extending in the vertical direction; a receiving member connecting the plurality of column members and for placing the building materials; and a roof member attached to the upper ends of the plurality of column members and projecting upward from the plurality of column members to constitute the roof of the loading rack, wherein the roof member comprises a plurality of roof members arranged at intervals in one of the longitudinal and width directions of the loading rack and extending in the other of the longitudinal and width directions of the loading rack to connect the plurality of column members, and a ridge member extending in a direction intersecting the extension direction of the roof members to connect the plurality of roof members, wherein the roof member has a column engaging portion that engages vertically and detachably with an engaging portion formed on the upper end of the column member, and the column engaging portion engages with the engaging portion by clamping the upper end of the column member from above. The above configuration makes it possible to create a loading rack that is easier to assemble than conventional racks. More specifically, the loading rack of the present invention is equipped with a roof member having a shed member and a ridge member, and is capable of storing building materials. The shed member engages with the upper end of the column member in a vertically detachable manner, and the ridge member connects multiple shed members. Therefore, the shed members and ridge members can be easily attached and detached. Furthermore, in the loading rack of the present invention, the column engagement portion of the shed member engages with the column member by clamping the upper end of the column member from above. Therefore, a loading rack that allows for more stable assembly of the roof member can be realized.

[0007] In this case, the shed member has a shed body that extends in a long length, and column engagement portions formed at both ends of the shed body in the direction of extension and extending downward from the shed body, and the column engagement portion has an upper wall portion facing the upper surface of the column member, a first side wall portion extending downward from one end of the upper wall portion and facing the first side surface of the upper end of the column member, a second side wall portion extending downward from the other end of the upper wall portion opposite to the one end side and facing the second side surface of the upper end of the column member opposite to the first side surface, and an engagement projection protruding downward from the upper wall portion and engaging with the engagement portion formed on the upper surface of the column member, and the upper end of the column member is preferably clamped by the first side wall portion and the second side wall portion. With the above configuration, the column engagement portion of the shed member engages with the column member (engaged portion) by surrounding the upper end of the column member with the upper wall portion, the first side wall portion, and the second side wall portion. The upper end of the column member is then clamped between the first side wall portion and the second side wall portion. Therefore, the roof member can be assembled to the main body of the loading rack more stably.

[0008] In this case, the first side wall portion is positioned to face the first side surface which is the inner surface of the column member, and the second side wall portion is positioned to face the second side surface which is the outer surface of the column member. The second side wall portion extends downward from the upper wall portion to be shorter than the first side wall portion, and the extended end of the second side wall portion is preferably inclined outward from the column member so as to move away from the column member. As described above, the second side wall is shorter than the first side wall, and the extended end of the second side wall extends inclined outward from the column member, allowing the roof member to be easily assembled to the pair of column members from above. In other words, by designing the shape of the second side wall, interference between the column member and the second side wall can be suppressed, and the roof member (column engagement portion) can suitably clamp the column member.

[0009] In this case, the column engagement portion has a convex-shaped engagement projection, the engaged portion of the column member is an engagement hole that engages with the engagement projection, the column member has a column upper wall portion on the upper surface of the column member and a support portion provided on the bottom or upper surface of the column upper wall portion, the engagement hole portion is composed of a first engagement hole portion formed by penetrating the column upper wall portion in the vertical direction and a second engagement hole portion that communicates with the first engagement hole portion and is formed by penetrating the support portion in the vertical direction, and the engagement projection portion is preferably engaged with the first engagement hole portion and the second engagement hole portion. As described above, the column engagement projection engages with the first engagement hole and the second engagement hole, respectively, allowing for a stronger connection between the pair of column members and the shed member. This prevents the shed member from shaking and collapsing after being assembled to the pair of column members.

[0010] In this case, the receiving member is provided with a pair of connecting members that are spaced apart in the extending direction of the receiving member and extend in a direction intersecting the extending direction of the receiving member to connect the plurality of column members, and the shed member has a first shed member that connects a pair of column members from the plurality of column members, and a second shed member that connects the pair of connecting members, and the column engaging portion of the second shed member is detachably engaged in the vertical direction with the engaged portion formed at the upper end of the connecting member, and the column engaging portions of the first shed member and the second shed member each have a common engagement method, and the engaged portions of the column members and the connecting member each have a common engagement method. The above configuration allows for the assembly of multiple shed components with a simple structure. Therefore, the building components can be effectively protected by the multiple shed components. Furthermore, by adopting a common engagement mechanism as described above, the components can be standardized. This allows workers to assemble the loading racks efficiently. It also reduces the cost of manufacturing the loading rack components.

[0011] In this case, the ridge member connects a first roof member, a second roof member and a third roof member arranged adjacent to the first roof member, and the ridge member preferably has a ridge body that extends in a long length, a first roof engagement portion formed in the center of the ridge body that engages with a first engagement portion provided on the first roof member in a vertically detachable manner, and a pair of second roof engagement portions formed at both ends in the extending direction of the ridge body that engage with a second engagement portion provided on the second roof member and the third roof member in a vertically detachable manner. With the above configuration, at least three roof members can be connected by the ridge member. Therefore, the number of parts in the ridge member can be reduced compared to the case where only two roof members are connected by the ridge member. In addition, the ridge member can be attached to the roof members more stably.

[0012] In this case, the rack preferably includes a pair of connecting members that are spaced apart in the extending direction of the receiving member and extend in a direction intersecting the extending direction of the receiving member, connecting the upper portions of the plurality of column members, and a sheet-like rack cover that covers the rack body of the loading rack, wherein the rack cover covers the rack body while being supported by the plurality of shed members, the ridge member, and the pair of connecting members. As described above, by covering the rack body with the rack cover while it is supported by the shed members, ridge members, and connecting members, it is possible to suppress the occurrence of sagging and wrinkles in the rack cover. Furthermore, by arranging multiple shed members, ridge members, and a pair of connecting members as described above, a more robust loading rack can be realized. In other words, building materials can be transported and stored effectively. [Effects of the Invention]

[0013] According to the loading rack of the present invention, it becomes possible to assemble it more easily than before. In addition, it becomes possible to stably assemble the roof member.

Modes for Carrying Out the Invention

[0015] Hereinafter, embodiments according to the present invention will be described with reference to FIGS. 1 to 12. This embodiment relates to a loading rack for transporting and storing building members in a loaded state, which enables easier assembly than before and also enables stable assembly of the roof member.

[0016] <Loading rack> As shown in Figure 1, the loading rack 1 is a rack capable of transporting multiple plate-shaped building components 2 while they are loaded onto it. For example, it can be used to transport building components 2 in a flat stacked state from a factory to a construction site by truck. Loading rack 1 may also be called a procurement logistics rack, transport rack, or storage rack, depending on its intended use. Loading rack 1 may be used commonly for all purposes, or it may be used exclusively for each purpose. The loading rack 1 is equipped with a roof member 90 as shown in Figure 1 and a rack cover 100 as shown in Figure 10, which can protect the interior from weather changes and dust in the atmosphere, and can also be used as a material storage facility at construction sites. The loading rack 1 is a rack whose overall length can be extended so that it can load and transport building materials 2 of various shapes and sizes, and even when its overall length is extended, it is a rack that can be lifted by a lifting device such as a crane.

[0017] Building materials 2 are plate-shaped components used in various types of buildings, and include building panels such as exterior wall panels, roof panels, and wainscoting panels, as well as wooden construction materials. Building materials 2 are also referred to as "delivery materials." When stacking building panels as building components 2, they are placed with a predetermined gap between them in the vertical direction to avoid damaging the finishing surface material. When stacking wooden construction components, they are piled up on a pallet and secured to the pallet with bands or the like.

[0018] As shown in Figure 1, the loading rack 1 comprises a frame-shaped base member (a pair of first base members 10, a pair of extension base members 20, and a pair of second base members 30), a plurality of column members 40 positioned at at least four corners of the base member and extending upward from the first base member 10, and holding members 50 and second holding members 55 that maintain the engaged state of the base member. Furthermore, the loading rack 1 includes an intermediate support member 60 that spans a pair of first base members 10 or a pair of extension base members 20, and a pair of support members 70 that extend in the width direction of the loading rack 1 and connect the column members 40 together. Furthermore, the loading rack 1 includes a pair of connecting members 80 that extend in the longitudinal direction of the loading rack 1 and connect the column members 40 together, and a roof member 90 that is attached to the upper ends of the multiple column members 40 and protrudes upward from the multiple column members 40 to form the roof of the loading rack 1. The roof member 90 has a shed member 91 and a ridge member 96. Furthermore, as shown in Figure 10, the loading rack 1 is further equipped with a sheet-like rack cover 100 that covers the entire rack body of the loading rack 1. The mounting positions and number of extension base members 20, column members 40, intermediate support members 60, support members 70, connecting members 80, and roof members 90 can be changed as appropriate. For example, they can be changed according to the load capacity of the building components 2.

[0019] <First base member, extension base member, second base member> As shown in Figures 1 to 5, the first base member 10, the extension base member 20, and the second base member 30 are members that form the base of the loading rack 1, and are made of elongated bodies processed from, for example, square pipes of metal material. They ensure the rigidity of the loading rack 1 and also function as receiving members on which the building members 2 are placed on the upper surface. The first base member 10 extends in a long length along the length of the loading rack 1 and connects the column members 40 to each other. The extension base member 20 extends in the longitudinal direction of the loading rack 1, similar to the first base member 10, and connects the column members 40 to each other. The second base member 30 extends lengthwise in the width direction of the loading rack 1 and connects the first base members 10 to each other or the extension base members 20 to each other.

[0020] As shown in Figures 1 to 4, the first base member 10 comprises a base body 11 and leg portions 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 the receiving part for the building component 2. The leg portion 15 is a support leg that supports the column member 40 from below and is attached to the outer surface of the base body 11 in the width direction.

[0021] Engagement holes 12 are formed at both ends of the base body 11 for horizontally attaching and detachably engaging the extension base member 20 (engagement projection 22) or the second base member 30 (engagement projection 33). On the upper surface of the base body 11, fixing holes 13 for fixing the intermediate support member 60 (fixing projection 63) are formed at intervals. Also, on the bottom surface of the base body 11, sling attachment points 14 for attaching the lifting member L1 of the lifting device L shown in Figure 11 are formed at intervals.

[0022] The upper end of the leg portion 15 is formed with a column engagement recess 16 for detachably engaging the column member 40 (engagement projection 42) in the vertical direction, and a slit-shaped support groove 17 for inserting the support projection 43. The column engagement recess 16 has a closed cross-sectional structure. The support groove 17 is formed on the inner surface of the column engagement recess 16 and is a groove that extends in the vertical direction. As shown in Figure 3, a keyway 52 is formed at the upper end of the boundary between the engagement hole 12 and the column engagement recess 16, spanning both the engagement hole 12 and the column engagement recess 16.

[0023] As shown in Figures 1 to 5, the extension base member 20 is interposed between the first base member 10 and the second base member 30, and is a member that extends the overall length of the loading rack 1. One end of the extension base member 20 in the longitudinal direction has an engagement shape similar to that of one end of the second base member 30, and the other end of the extension base member 20 has an engagement shape similar to that of the other end of the first base member 10. The extension base member 20 comprises a base body 21 and a leg portion 25 attached to the other end of the base body 21 in the longitudinal direction and extending downward from the base body 11.

[0024] An engaging projection 22 is formed at one end of the base body 21 in the longitudinal direction, which engages horizontally and detachably with the first base member 10 (engagement hole portion 12). An engagement hole 24 is formed at the other end of the base body 21 in the longitudinal direction, which engages horizontally and detachably with the second base member 30 (engagement projection 33). Specifically, the engaging projection 22 has a U-shaped vertical cross-section and includes a main wall portion 22a that protrudes toward the first base member 10 and a pair of reinforcing wall portions 22b. As shown in Figure 3, a second keyway 53 is formed on the outer side of the engaging projection 22. The second keyway 53 is a slit-shaped groove for fitting the locking member 51 of the column member 40.

[0025] The upper end of the leg portion 25 is formed with a column engagement recess 26 for detachably engaging the column member 40 (engagement projection 42) in the vertical direction, and a slit-shaped support groove 27 for inserting the support projection 43. As shown in Figure 2, a keyway 57 is formed at the upper end of the boundary between the engagement hole 24 and the column engagement recess 26, spanning both the engagement hole 24 and the column engagement recess 26. The keyway 57 is a slit-shaped groove for fitting the convex locking member 56 of the column member 40.

[0026] In the above configuration, as shown in Figures 3 and 4, when the extension base member 20 is assembled to the first base member 10, the longitudinal end face of the base body 21 abuts against the side surface of the first base member 10, and the engaging projection 22 engages with the engaging hole 12. By doing so, the assembly rigidity of the loading rack 1 can be increased while eliminating the need for bolt fastening.

[0027] As shown in Figures 1 and 2, the second base member 30 is a member connected to a pair of first base members 10 or a pair of extension base members 20. The second base member 30 comprises a second base body 31, extensions 32 attached to the sides of both ends of the second base body 31 in the longitudinal direction and extending outward in the longitudinal direction, and engaging protrusions 33 formed at the extension ends of a pair of extensions 32 and engaging with the extension base member 20 (engagement hole portion 24) or the first base member 10 (engagement hole portion 12). Furthermore, a second keyway 58 is formed on the outer side of the engaging projection 33. The second keyway 58 is a slit-shaped groove for fitting the locking member 56 of the column member 40.

[0028] The second base body 31 serves as the receiving portion for the building component 2. The extension portion 32 is attached to the outer surface of the second base body 31 and is positioned so as not to protrude above the second base body 31. The engaging projection 33 protrudes laterally from the extension 32 and engages with the engaging hole 24 (engaging hole 12) in a horizontally detachable manner. Specifically, the engaging projection 33 has a U-shaped vertical cross-section and includes a main wall portion that protrudes from the extension portion 32 toward the extension base member 20, and a pair of reinforcing wall portions.

[0029] In the above configuration, as shown in Figures 1 and 2, when the second base member 30 is assembled to the extension base member 20, the longitudinal end face of the second base body 31 abuts against the side surface of the extension base member 20, the side surface of the extension portion 32 abuts against the end face of the extension base member 20, and the engaging projection 33 engages with the engaging hole portion 24. By doing so, the assembly rigidity of the loading rack 1 can be increased while eliminating the need for bolt fastening.

[0030] <Column members> As shown in Figures 1 to 4, the column members 40 are members that serve as support columns for the loading rack 1, and are made of long bodies processed from, for example, square pipes, and are arranged at the four corners and the middle section of the loading rack 1, with a total of eight members provided. Specifically, the column member 40 comprises a column body 41 with a rectangular cross-section that is elongated in the vertical direction, an engaging projection 42 formed at the lower end of the column body 41 that engages with the first base member 10 (column engaging recess 16), a support projection 43 protruding from the inner surface of the column body 41, and a clamping portion 45 protruding from the outer surface of the column body 41. As shown in Figures 2 to 4, convex locking members 51 and 56 are formed on the inner surface of the column body 41. Furthermore, as shown in Figure 6, the column member 40 is provided in the upper part of the column body 41 and has fitting holes 46 and a second fitting hole 47 that protrude from the side surface of the column body 41 toward opposite sides and engage with the connecting member 80 (fitting projection 82) or the receiving member 70 (second fitting projection 73). Furthermore, as shown in Figures 7 to 9, the column member 40 is provided at the upper end of the column body 41 and has an engagement hole 48 that engages with the roof member 90 (the column engagement portion 93 of the shed member 91).

[0031] As shown in Figures 3 and 4, the engaging projection 42 has a closed cross-section (rectangular cross-section). The support projection 43 protrudes from the inner surface of the engaging projection 42 and extends in the vertical direction. The column member 40 is assembled to the first base member 10 (leg portion 15) in the vertical direction by the engagement projection 42 fitting into the column engagement recess 16. At this time, the support projection 43 is inserted into the support groove 17 and held in place by the support groove 17. Therefore, when assembling the column member 40 to the first base member 10, it becomes easier to position the column member 40. In addition, the rigidity of the first base member 10 and the column member 40 can be increased.

[0032] The clamping portion 45 is a bent-shaped pressing member that protrudes from the outer surface of the engaging projection 42 and is formed on the opposite side from the support projection 43. The clamping portion 45 can clamp the column engagement recess 16 of the first base member 10 with the engagement projection 42. Therefore, the column member 40 can be firmly attached to the first base member 10.

[0033] As shown in Figure 6, the fitting holes 46 and second fitting holes 47 are formed in multiple locations spaced apart in the vertical direction and share a common fitting mechanism. The fitting holes 46 and second fitting holes 47 are also referred to as fitting pockets. The fitting hole portion 46 is located on the inner surface of the column member 40 in the longitudinal direction of the loading rack 1, and the second fitting hole portion 47 is located on the outer surface of the column member 40. The fitting hole 46 engages with the connecting member 80 (fitting projection 82), and the second fitting hole 47 engages with the receiving member 70 (second fitting projection 73), but this is not particularly limited. For example, the fitting hole 46 may engage with the second fitting projection 73, and the second fitting hole 47 may engage with the fitting projection 82.

[0034] As shown in Figures 7 to 9, the engagement hole portion 48 is formed at the upper end of the column member 40 and engages with the shed member 91 (column engagement portion 93) in a vertically detachable manner. Specifically, the column member 40 has a column upper wall portion 41a located on the upper surface of the column body 41, and a support portion 41b provided on the bottom surface of the column upper wall portion 41a. The column upper wall portion 41a is a plate-shaped plate welded to the upper surface of the column body 41, which has a rectangular cross-section. The support portion 41b is, for example, a support nut, welded to the bottom surface of the column upper wall portion 41a (it may also be welded to the upper surface of the column upper wall portion 41a). The engagement hole portion 48 is composed of a first engagement hole portion 48a formed by penetrating the column upper wall portion 41a in the vertical direction, and a second engagement hole portion 48b that communicates with the first engagement hole portion 48a and is formed by penetrating the support portion 41b in the vertical direction.

[0035] With the above configuration, as shown in Figures 7 to 9, the column member 40 and the roof member 90 can be connected without the need for bolt fastening.

[0036] <Holding member, second holding member> As shown in Figures 3 and 4, the retaining member 50 is a member that maintains the engaged state when the extension base member 20 (engagement projection 22) is engaged horizontally with the first base member 10 (engagement hole 12). More specifically, the retaining member 50 is provided at the connecting portion between the first base member 10 and the extension base member 20, and maintains the engaged state in the engagement direction (the longitudinal direction of the loading rack 1) and the vertical direction. The retaining member 50 includes a convex-shaped locking member 51 provided at the lower end of the column member 40, a keyway 52 formed in the engagement hole 12 of the first base member 10, and a second keyway 53 formed in the engagement projection 22 of the extension base member 20.

[0037] The locking member 51 is formed adjacent to the support projection 43 and protrudes outward from the support projection 43. The locking member 51 engages and locks the first base member 10, the extension base member 20, and the column member 40 by fitting into both the overlapping keyway 52 and the second keyway 53.

[0038] In the above configuration, as shown in Figures 3 and 4, the keyway 52 of the first base member 10 and the second keyway 53 of the extension base member 20 are arranged to overlap, and the locking member 51 fits into both the keyway 52 and the second keyway 53. In this way, the first base member 10, the extension base member 20, and the column member 40 are locked together. By providing the holding member 50 in this way, the loading rack 1 can be assembled easily and securely.

[0039] As shown in Figure 2, the second retaining member 55 is a member that maintains the engaged state when the second base member 30 (engagement projection 33) is engaged horizontally with the extension base member 20 (engagement hole 24). More specifically, the second retaining member 55 is provided at the connecting portion between the extension base member 20 and the second base member 30, and maintains the engaged state in the engagement direction (the longitudinal direction of the loading rack 1) and the vertical direction. The second retaining member 55 has the same configuration as the retaining member 50.

[0040] The second retaining member 55 includes a convex-shaped locking member 56 provided at the lower end (engaging projection 42) of the column member 40, a keyway 57 formed in the engagement hole 24 of the extension base member 20, and a second keyway 58 formed in the engagement projection 33 of the second base member 30.

[0041] In the above configuration, as shown in Figure 2, the keyway 57 of the extension base member 20 and the second keyway 58 of the second base member 30 are arranged to overlap, and the locking member 56 fits into both the keyway 57 and the second keyway 58. In this way, the extension base member 20, the second base member 30 and the column member 40 are locked together. By configuring the locking member 56 and keyways 57 and 58 in this way, the loading rack 1 can be assembled easily and securely.

[0042] <Intermediate support member> As shown in Figures 1 and 5, the intermediate support member 60 is a member that spans a pair of first base members 10, a pair of extension base members 20, or a pair of connecting members 80, and is made of, for example, a long body processed from a square pipe, and functions as a support member on which the building member 2 is placed. Specifically, the intermediate support member 60 comprises a support body 61 that is elongated in the width direction of the loading rack 1, mounting portions 62 formed at both ends of the support body 61 in the length direction and clamping the base body 11 (base body 21, connecting body 81), and fixing protrusions 63 provided on the inner surface of the mounting portion 62 and projecting from the inner surface of the mounting portion 62 toward the upper surface of the base body 11.

[0043] The mounting portion 62 is detachably attached to the base body 11 (base body 21, connecting body 81) from above, and clamps the base body 11 so as to surround it. The fixing projection 63 protrudes downward from the bottom surface of the mounting portion 62 and is detachably fixed to the fixing hole portion 13 provided on the upper surface of the base body 11.

[0044] As described above, by providing the intermediate support member 60 with a mounting portion 62 and a fixing projection 63, the assembly rigidity of the loading rack 1 can be increased without requiring bolt fastening. Furthermore, the intermediate support member 60 is assembled to the first base member 10 (extension base member 20, connecting member 80) with its horizontal movement restricted. As a result, the intermediate support member 60 allows for more stable loading of the building components 2.

[0045] <Support members, connecting members> As shown in Figures 1 and 6, the support member 70 is a member that connects the column members 40 arranged in the width direction of the loading rack 1, and in addition to providing rigidity to the loading rack 1, it also functions as a support member on which the building components 2 are placed. Specifically, the receiving member 70 has a long receiving body 71, extensions 72 attached to the sides of both ends of the receiving body 71 in the longitudinal direction and extending outward in that longitudinal direction, and a pair of second fitting protrusions 73 formed at the extension ends of the extensions 72 and fitting into the column member 40 (second fitting hole 47). The second fitting projection 73 fits into the second fitting hole 47 using a wedge mechanism.

[0046] In the above configuration, as shown in Figure 6, when the receiving member 70 is assembled to the column member 40, the longitudinal end face of the receiving body 71 abuts against the side surface of the column member 40, the extension portion 72 abuts against the outer surface of the column member 40, and the second fitting projection 73 is fitted into the second fitting hole portion 47. By doing so, the assembly rigidity of the loading rack 1 can be increased while eliminating the need for bolt fastening.

[0047] As shown in Figures 1, 6 to 8, the connecting member 80 serves the function of connecting the column members 40 arranged along the length of the loading rack 1, and also the function of additionally assembling the shed members 91. Furthermore, the connecting member 80 functions as a member that provides rigidity to the loading rack 1. Specifically, the connecting member 80 has a connecting body 81 that is elongated in the longitudinal direction of the loading rack 1, and fitting projections 82 that are attached to both ends of the connecting body 81 in the longitudinal direction and fit into the column members 40 (fitting holes 46, 47). Furthermore, an engagement hole 83 is formed on the upper surface of the connecting member 80, which allows the shed member 91 (column engagement portion 93) to be detachably engaged in the vertical direction.

[0048] The fitting projection 82 is attached to the longitudinal end face of the connecting body 81 and protrudes downward from the connecting body 81, and is fitted to the fitting holes 46 and 47 from above in a detachable manner. In other words, the fitting projection 82 fits to the fitting holes 46 and 47 in a wedge-like manner. As shown in Figure 6, when the connecting member 80 is assembled to the column member 40, the end face of the fitting projection 82 abuts against the side surface of the column member 40, and the fitting projection 82 is fitted into the fitting hole 46. This makes it possible to increase the assembly rigidity of the loading rack 1 without requiring bolt fastening. Furthermore, as shown in Figures 7 and 9, when the connecting member 80 is connected to the upper end of the column member 40, the upper surface of the connecting member 80 and the upper surface of the column member 40 become substantially flush.

[0049] As shown in Figure 6, the connecting member 80 (fitting projection 82) fits into the column member 40 (fitting hole 46), and the receiving member 70 (second fitting projection 73) fits into the column member 40 (second fitting hole 47). The column member 40 is surrounded by the connecting member 80, the receiving member 70 (receiving body 71), and the extension 72. By doing so, the assembly rigidity of the loading rack 1 can be increased while avoiding interference between the connecting member 80 and the receiving member 70.

[0050] The engagement hole portion 83 has the same engagement method as the engagement hole portion 48 of the column member 40. The engagement hole 48 can engage with the column engagement portion 93 of the shed member 91 by surrounding it. Therefore, bolt fastening can be eliminated. As shown in Figure 7, the engagement hole portion 83 is a through hole formed on the upper surface of the connecting member 80, while the engagement hole portion 48 of the column member 40 has a first engagement hole portion 48a and a second engagement hole portion 48b, as shown in Figure 8. In other words, the shed member 91 engages more firmly with the column member 40 (engagement hole portion 48) than with the connecting member 80 (engagement hole portion 83). Multiple roof members 91 are connected by a ridge member 96, and a given roof member 91 is firmly engaged with a column member 40. Therefore, the roof members 91 as a whole can be assembled stably. Similarly, the engagement hole portion 83 may also be composed of a first engagement hole portion (through hole) and a second engagement hole portion (hole for the support nut). In other words, a support nut may be provided inside the connecting member 80.

[0051] <Roofing components (shed components, ridge components)> As shown in Figures 1, 7 to 10, the roof member 90 is arranged in multiples at intervals along the length of the loading rack 1 and comprises roof members 91 that form a roof structure, and ridge members 96 that form the uppermost part (ridge) of the roof, extend along the length of the loading rack 1, and are attached to the upper ends of the multiple roof members 91. In this embodiment, the roof member 90 is composed of five shed members 91 and two ridge members 96. Each of the four shed members 91 engages with a column member 40, and one of the shed members 91 engages with a connecting member 80.

[0052] The shed member 91 has a shed body 92 that is elongated in the width direction of the loading rack 1, column engagement portions 93 formed at both ends in the length direction of the shed body 92 and extending downward from the shed body 92, and a first engagement bracket 94 and a second engagement pocket 95 provided at the upper end of the shed body 92. The shed body 92 is, for example, a pipe made of metal material and is formed to form an inverted V shape. Specifically, the shed body 92 is composed of a first extension portion that extends downward from its upper end while sloping away from each other, and a second extension portion that extends downward from the extension end of the first extension portion.

[0053] As shown in Figures 7 to 9, the column engagement portion 93 is detachably engaged with the column member 40 (engagement hole portion 48) or the connecting member 80 (engagement hole portion 83). Specifically, the column engagement portion 93 includes an upper wall portion 93a facing the upper surface of the column member 40, a first side wall portion 93b extending downward from the inner end of the upper wall portion 93a and facing the first side surface (inner surface) of the column member 40, a second side wall portion 93c extending downward from the outer end of the upper wall portion 93a and facing the second side surface (outer surface) of the column member 40, and an engagement projection 93d protruding downward from the upper wall portion 93a and engaging with the column member 40 (engagement hole portion 48). The column engagement portion 93 clamps the upper end of the column member 40 with the first side wall portion 93b and the second side wall portion 93c, and engages with the column member 40 (engagement hole portion 48) with the engagement projection portion 93d. As a result, the assembly rigidity of the roof member 90 can be increased while eliminating the need for bolt fastening. As shown in Figure 8, the shed body 92 and the column engagement portion 93 (first side wall portion 93b) are connected by a reinforcing plate 93e.

[0054] In the above configuration, as shown in Figure 8, the second side wall portion 93c extends downward from the upper wall portion 93a to be shorter than the first side wall portion 93b. Specifically, the second side wall portion 93c extends longer than the engaging projection portion 93d and shorter than the first side wall portion 93b. Furthermore, the extended end of the second side wall portion 93c extends inclined outward from the column member 40, moving away from the column member 40. In other words, the extended end of the second side wall portion 93c is bent so as to open outward. This allows the shed member 91 to be easily assembled to the pair of column members 40 from above. In other words, interference between the column members 40 and the second side wall portion 93c is suppressed, and the shed member 91 (column engaging portion 93) can suitably clamp the column members 40.

[0055] In the above configuration, as shown in Figure 9, the column engagement portion 93 (engaging projection 93d) engages with the first engagement hole portion 48a and the second engagement hole portion 48b (inside the support nut) of the column member 40. This prevents the shed member 91 from shaking and collapsing after it has been assembled to the pair of column members 40.

[0056] In the above configuration, as shown in Figure 8, the shed member 91 connects a pair of column members 40 and also connects a pair of connecting members 80. Furthermore, the shed member 91 and the column engagement portion 93 of each shed member 91 have a common engagement method. In addition, the column member 40 and the connecting member 80 have engagement holes 48 and 83 of each, respectively, have a common engagement method. This allows for the assembly of multiple shed members 91 with a simple structure. Furthermore, by adopting a common engagement method, the components can be standardized. As a result, workers can efficiently assemble the loading rack 1. This also reduces the cost of manufacturing the parts for the loading rack 1.

[0057] As shown in Figure 10, the first engagement bracket 94 is a member that is detachably engaged with the ridge member 96 (first roof engagement portion 98). Specifically, the first engaging bracket 94 has an upper wall portion 94a facing the upper surface of the shed body 92, a first side wall portion 94b extending downward from the inner end of the upper wall portion 94a, a second side wall portion 94c extending downward from the outer end of the upper wall portion 94a, an extended end of the second side wall portion 94c, and a connecting wall portion 94d that connects to the shed body 92. Furthermore, an engagement hole 94e is formed on the upper surface of the upper wall portion 94a, which is detachably engaged with the ridge member 96 (engagement shaft 98d). The second engagement pocket 95 is formed on the side surfaces of the first side wall portion 94b and the second side wall portion 94c, respectively, and is detachably engaged with the ridge member 96 (second roof engagement portion 99).

[0058] As shown in Figure 10, the ridge member 96 is a metal pipe extending in the longitudinal direction of the loading rack 1, and is a member that connects the upper ends of the shed members 91. The ridge member 96 connects the first roof member 91A, the second roof member 91B which is positioned adjacent to the first roof member, and the third roof member 91C. As a result, the assembly rigidity of the roof member 90 can be increased while eliminating the need for bolt fastening. Specifically, the ridge member 96 includes a long ridge body 97, a first roof engagement portion 98 formed in the center of the ridge body 97, and a pair of second roof engagement portions 99 formed at both ends of the ridge body 97 in the direction of extension.

[0059] The first shed engagement portion 98 clamps the second shed member 91B (first engagement bracket 94) and is also detachably engaged with the first engagement bracket 94. Specifically, the first shed engagement portion 98 includes an upper wall portion 98a, a first side wall portion 98b extending downward from the inner end of the upper wall portion 98a and facing the inner surface of the first engagement bracket 94, a second side wall portion 98c extending downward from the outer end of the upper wall portion 98a and facing the outer surface of the first engagement bracket 94, and an engagement shaft 98d protruding downward from the upper wall portion 98a and engaging with the engagement hole 94e.

[0060] The second shed engagement portion 99 is an engagement projection that engages with the first shed member 91A (second engagement pocket 95) and the third shed member 91C (second engagement pocket 95) in a vertically detachable manner. Specifically, the second shed engagement portion 99 engages with the second engagement pocket 95 using a wedge mechanism. Furthermore, the ridge member 96 (second roof engagement portion 99), the connecting member 80 (fitting projection 82), and the receiving member 70 (second fitting projection 73) share a common engagement method (fitting method). Similarly, the roof member 91 (second engagement pocket 95) and the column member 40 (fitting hole portion 46, second fitting hole portion 47) also share a common engagement method. This allows workers to assemble the loading rack 1 efficiently. Furthermore, by adopting a common engagement mechanism, the components can be standardized.

[0061] <rack cover> As shown in Figures 11 and 12, the rack cover 100 is a sheet-like cover that covers the entire body of the loading rack 1 from above. The rack cover 100 has opening and closing sections 101 formed on both ends in the longitudinal direction to allow the building components 2 to be removed. Similarly, the rack cover 100 also has opening and closing sections 101 formed on both ends in the width direction. With the above configuration, as shown in Figure 11, a portion of the rack cover 100 can be easily opened and closed. Furthermore, the building materials 2 can be easily removed from the covered loading rack 1.

[0062] In the above configuration, as shown in Figure 11, the covered loading rack 1 can be lifted by hooking the lifting member L1 of the lifting device L onto the four sling attachment points 14 of the loading rack 1. In this configuration, the shed members 91 are provided at both ends of the loading rack 1 in the longitudinal direction. The ridge member 96 is positioned in the center of the loading rack 1 in the width direction and also at the upper end of the loading rack 1. The connecting members 80 are positioned at both ends of the loading rack 1 in the width direction. Therefore, as shown in Figure 11, when the loading rack 1 is lifted by the lifting device L, measures can be taken to prevent the lifting member L1 from being squeezed and coming into contact with the building member 2. Specifically, since the building member 2 is loaded so that it is surrounded by the connecting member 80 and the roof member 90, it is possible to suppress the lifting member L1 from coming into contact with the building member 2 when it is squeezed.

[0063] In the above configuration, as shown in Figures 11 and 12, the rack cover 100 covers the rack body while being supported by the shed member 91, the ridge member 96, and the connecting member 80. Therefore, it is possible to suppress the occurrence of sagging and wrinkles in the rack cover 100. Furthermore, the portion of the rack cover 100 corresponding to the sling attachment portion 14 may be provided with an opening / closing section for exposure, allowing the sling attachment portion 14 to be exposed to the outside. Doing so will further suppress the occurrence of sagging and wrinkles in the rack cover 100.

[0064] With the above-described loading rack 1, workers can easily assemble it, and building materials 2 can be suitably transported and stored. Furthermore, with the loading rack 1, workers can stably assemble the roof materials 90. In addition, by providing the extension base member 20, the overall length of the loading rack 1 can be extended so that building materials 2 of various shapes and sizes can be loaded.

[0065] <Other> In the above embodiment, as shown in Figure 1, the loading rack 1 is composed of two first base members 10, four extension base members 20, two second base members 30, eight column members 40, six intermediate support members 60, two support members 70, twelve connecting members 80, and a roof member 90 (five roof members and two ridge members). However, the number of parts for each component is not particularly limited and can be changed. For example, the number of intermediate support members 60 may be increased to enhance the rigidity of the loading rack 1 and to allow for the suitable loading of building materials 2. Alternatively, the height of the loading rack 1 can be increased by arranging and connecting the column members 40 in the vertical direction. In that case, it is advisable to prepare column members 40 of different heights.

[0066] In the above embodiment, as shown in Figure 1, the intermediate support member 60 is spanned across a pair of first base members 10 (a pair of connecting members 80), but it is not particularly limited and may be spanned across a pair of second base members 30 or a pair of support members 70.

[0067] In the above embodiment, as shown in Figure 7, the shed member 91 extends in the width direction of the loading rack 1, but it is not particularly limited and may extend in the length direction of the loading rack 1. In that case, it is preferable for the ridge member 96 to extend in the width direction of the loading rack 1 and connect the shed members 91 together.

[0068] In the above embodiment, as shown in Figure 7, the shed member 91 connects the column members 40 together, as well as the connecting members 80 together, but this is not particularly limited. For example, the shed members 91 may connect only the column members 40, or the shed members 91 may connect only the connecting members 80.

[0069] In the above embodiment, as shown in Figure 10, the ridge member 96 connects the three roof members 91, but this is not particularly limited. For example, the ridge member 96 may connect four or more roof members 91, or it may connect two roof members.

[0070] In the above embodiment, as shown in Figure 7, the shed member 91 has a convex column engaging portion 93 (engaging projection 93d) and the column member 40 has a concave engaging hole portion 48. However, the concave and convex structures may be reversed. In other words, the shed member 91 may have a concave column engaging portion and the column member 40 may have a convex engaged portion. Similarly, the ridge member 96 has a convex first shed engagement portion 98 (engagement shaft 98d), and the shed member 91 has a concave first engagement bracket 94 (engagement hole 94e), but the convex and concave structures may be reversed. Also, the ridge member 96 has a convex second shed engagement portion 99, and the shed member 91 has a concave second engagement pocket 95, but the convex and concave structures may be reversed. Alternatively, the engagement method is not particularly limited, as long as it is a structure that can be detachably engaged with one another, regardless of whether it is a concave or concave structure (for example, a key-shaped structure).

[0071] The above embodiments mainly described the loading rack according to the present invention. However, the embodiments described above are merely examples to facilitate understanding of the present invention and do not limit it. The present invention can be modified and improved without departing from its spirit, and of course, equivalents thereof are included. In particular, the embodiments described above are merely examples and do not limit the present invention. [Explanation of Symbols]
