Description

[Technical field]

[0001] The present invention relates to a loading rack, and more particularly to a loading rack for transporting and storing construction materials loaded thereon. [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 can be used as a storage rack on-site by providing a roof member 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] By the way, when using a loading rack such as that described in Patent Document 2, a series of operations can be carried out, from transporting architectural panels or wooden construction components from a factory to a construction site and storing them at the construction site, but there is room for further improvement. For example, there was a demand for a loading rack that could be assembled more easily than before, or for a device that would prevent the lifting member (sling) from being squeezed and coming into contact with the load when lifted by a lifting device (crane).

[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 can be assembled more easily than conventional racks. Another object of the present invention is to provide a loading rack that can be lifted more suitably by a lifting device than in the past. [Means for solving the problem]

[0006] The above problem is solved by a loading rack of the present invention, which provides a loading rack for transporting and storing building materials loaded thereon, comprising: a plurality of pillar members arranged at at least four corners of the loading rack and extending in the vertical direction; a support member for connecting the plurality of pillar members and placing the building materials on the loading rack; and a roof member attached to the upper ends of the plurality of pillar members and protruding upward from the plurality of pillar members to form the roof of the loading rack, wherein the roof members are arranged at intervals in one of the length and width directions of the loading rack and extend in the other of the length and width directions of the loading rack to connect the plurality of pillar members; and a ridge member extending in a direction intersecting the extension direction of the ridge members to connect the plurality of ridge members, wherein the ridge members have pillar engaging portions that are detachably engageable in the vertical direction with engaged portions formed at the upper ends of the pillar members, and the ridge member has a ridge engaging portion that is detachably engageable with the engaged portion formed on the ridge member. The above configuration makes it possible to realize a loading rack that can be assembled more easily than before. 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 transporting and storing building materials. The shed member is detachably engaged in the vertical direction with the upper ends of the column members, and the ridge member is detachably engaged with the shed member. Therefore, the shed member and the ridge member can be easily attached and removed. In other words, it is possible to assemble the loading rack more easily than before.

[0007] In this case, the receiving member and the shed member are arranged at intervals in the longitudinal direction of the loading rack and extend in the width direction of the loading rack, and one of the pillar engaging portion of the shed member and the engaged portion of the pillar member is an engaging convex portion, the other of the pillar engaging portion and the engaged portion is an engaging hole portion that engages with the engaging convex portion, and the shed engaging portion of the ridge member and one of the engaged portions of the shed member is an engaging convex portion, and the other of the shed engaging portion and the engaged portion is an engaging hole portion that engages with the engaging convex portion. As described above, the roof member engages with the upper ends of the pillar members with a concave-convex structure, and the ridge member engages with the roof member with a concave-convex structure, making it easier to assemble the roof member and the ridge member.

[0008] In this case, the shed member has a long extending shed body and a pillar engaging portion formed at both ends of the shed body in the extension direction and extending downward from the shed body, and a step portion is formed in the portion between the extending end of the shed body and the pillar engaging portion, and the shed member is attached to the pillar member by the step portion abutting the upper surface of the pillar member and the pillar engaging portion being inserted into the engaged portion formed on the upper surface of the pillar member. With the above-mentioned configuration, the pillar engaging portion of the roof member can be easily assembled to the engaged portion formed on the upper surface of the pillar member by utilizing the step portion of the roof member. Also, the pillar member and the roof member can be firmly assembled.

[0009] In this case, it is preferable to provide a pair of connecting members that are arranged at intervals in the extending direction of the receiving member, extend in a direction intersecting the extending direction of the receiving member, and connect the multiple pillar members, the connecting members connecting the upper ends of the multiple pillar members, the connecting members being formed on both ends of the connecting members in the extending direction, and having engaging portions that are detachably engaged in the vertical direction with engaging portions provided on the side surfaces of the upper ends of the pillar members. As described above, by providing a pair of connecting members, it is possible to devise a method for preventing the hanging member (sling) from being squeezed and coming into contact with the load (construction material) when the loading rack is lifted by a lifting device (crane). Specifically, since the construction material is loaded so as to be surrounded by the roof material and the connecting members, it is possible to prevent the hanging member from coming into contact with the construction material when the hanging member is squeezed. Furthermore, as described above, since the connecting member is detachably engaged with the upper end of the pillar member in the vertical direction, the connecting member can be easily attached and removed.

[0010] In this case, the roof member has a first roof member connecting a pair of pillar members among the multiple pillar members, and a second roof member connecting the pair of connecting members, and the second roof member is removably engaged in the vertical direction with an engaged portion formed on the upper surface of the connecting member, and the first roof member and the second roof member are arranged side by side with a gap between them. With the above-mentioned configuration, since multiple shed members can be assembled, the building materials can be appropriately protected by the multiple shed members. In addition, when the rack cover is attached to the main body of the loading rack, if multiple shed members are provided, the occurrence of warping or wrinkles in the rack cover can be suppressed.

[0011] In this case, a sheet-like rack cover is provided to cover the rack body of the loading rack, the shed members are arranged at intervals in the longitudinal direction of the loading rack, and a pair of the shed members are provided at both ends of the longitudinal direction of the loading rack, the ridge member is arranged in the central portion of the width direction of the loading rack and is provided at the upper end of the loading rack, the connecting members are arranged at intervals in the width direction of the loading rack, and a pair of the connecting members are provided at both ends of the width direction of the loading rack, and the rack cover covers the rack body while being supported by the shed members, the ridge members and the connecting members. As described above, by covering the rack body while being supported by the shed member, ridge member and connecting member, the occurrence of bending or wrinkling in the rack cover can be suppressed. In addition, by arranging the shed members, ridge members, and connecting members as described above, a stronger loading rack can be realized. In other words, the building materials can be transported and stored in an optimal manner. Effect of the Invention

[0012] The loading rack of the present invention can be assembled more easily than before. In addition, the lifting device can lift the load more effectively than in the past. For example, it is possible to prevent the lifting member from being squeezed when the load is lifted by the lifting device and coming into contact with the load. [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 for transporting and storing construction materials loaded thereon, which can be assembled more easily than conventional "loading racks" and can be conveniently lifted by a lifting device.

[0015] <Loading rack> As shown in Fig. 1, the loading rack 1 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, a storage 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. The loading rack 1 is equipped with a roof member 90 shown in FIG. 1 and a rack cover 100 shown in FIG. 10, and can protect the inside from changes in weather and dust in the air, and can also be used as a material storage facility at a construction site. The loading rack 1 is a rack whose overall length can be extended so that building components 2 of various shapes and sizes can be loaded and transported, and even when the overall length is extended, the rack can be hoisted by a hoisting device such as a crane.

[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, a pair of extended base members 20, and a pair of second base members 30), a plurality of pillar members 40 arranged at at least four corners of the base members and extending upward from the first base member 10, and a retaining member 50 and a second retaining member 55 that maintain the engaged state of the above-mentioned base members. The loading rack 1 also includes an intermediate support member 60 that is spanned between a pair of first base members 10 or a pair of extended base members 20, a pair of connecting members 65 that extend in the longitudinal direction of the loading rack 1 and connect the pillar members 40 together, and a pair of support members 70 that extend in the width direction of the loading rack 1 and connect the pillar members 40 together. The loading rack 1 also includes a pair of connecting members 80 that extend in the length direction of the loading rack 1 and connect the upper ends of the pillar members 40 together, and a roof member 90 that is attached to the upper ends of the plurality of pillar members 40 and protrudes upward from the plurality of pillar 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. 10, the loading rack 1 further includes a sheet-like rack cover 100 that covers the entire rack body of the loading rack 1. As shown in FIG. The attachment positions and numbers of the extension base member 20, the pillar member 40, the intermediate support member 60, the connecting member 65, the support member 70, the connecting member 80, and the roof member 90 can be changed as appropriate. For example, they can be changed according to the load of the building members 2.

[0018] <First base member, extended base member, second base member> As shown in Figures 1 to 5, the first base member 10, the extended base member 20, and the second base member 30 are members that form the foundation of the loading rack 1 and are made of long bodies, for example, processed 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 40 together. The extension base member 20, like the first base member 10, extends in the length direction of the loading rack 1 and connects the pillar members 40 together. The second base member 30 extends elongated in the width direction of the loading rack 1, and connects the first base members 10 together or the extension base members 20 together.

[0019] As shown in Figs. 1 to 4, 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 40 from below, and are attached to the outer side surfaces of the base body 11 in the width direction.

[0020] At both ends of the base body 11, engagement holes 12 are formed for horizontally and detachably engaging the extension base member 20 (engagement protrusion 22) or the second base member 30 (engagement protrusion 33). Fixing holes 13 for fixing the intermediate receiving member 60 (fixing protrusions 63) are formed at intervals on the upper surface of the base body 11. In addition, sling hook portions 14 for hooking the hoisting member L1 of the hoisting device L shown in FIG. 11 are formed at intervals on the bottom surface of the base body 11.

[0021] The upper end of the leg 15 is formed with a column engagement recess 16 for detachably engaging the column member 40 (engagement protrusion 42) in the vertical direction, and a slit-shaped support groove 17 for inserting the support protrusion 43 therethrough. The column engagement recess 16 has a closed 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. As shown in FIG. 3, a key groove 52 is formed at the upper end of the boundary between the engagement hole portion 12 and the pillar engagement recess 16, straddling the engagement hole portion 12 and the pillar engagement recess 16.

[0022] The extension base member 20, as shown in FIGS. 1 to 5, is a member that is interposed between the first base member 10 and the second base member 30 and 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 one end of the second base member 30, and the other end of the extension base member 20 has an engagement shape similar to the other end of the first base member 10. The extension base member 20 includes 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.

[0023] An engagement protrusion 22 that is horizontally and detachably engaged with the first base member 10 (engagement hole 12) is formed at one end in the length direction of the base body 21. An engagement hole 24 that is horizontally and detachably engaged with the second base member 30 (engagement protrusion 33) is formed at the other end in the length direction of the base body 21. Specifically, the engagement protrusion 22 has a U-shaped vertical cross section, and includes a main body wall portion 22a that protrudes toward the first base member 10, and a pair of reinforcing wall portions 22b. 3, a second key groove 53 is formed on the outer side of the engagement protrusion 22. The second key groove 53 is a slit-like groove into which the lock member 51 of the pillar member 40 is fitted.

[0024] The upper end of the leg 25 is formed with a pillar engagement recess 26 for detachably engaging the pillar member 40 (engagement protrusion 42) in the vertical direction, and a slit-shaped support groove 27 for inserting the support protrusion 43 therethrough. 2, a key groove 57 is formed at the upper end of the boundary between the engagement hole portion 24 and the pillar engagement recess 26, straddling the engagement hole portion 24 and the pillar engagement recess 26. The key groove 57 is a slit-like groove into which the convex lock member 56 of the pillar member 40 is fitted.

[0025] 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 of the first base member 10, and the engagement protrusion 22 engages with the engagement hole portion 12. This makes it possible to increase the assembly rigidity of the loading rack 1 while eliminating the need for bolt fastening.

[0026] The second base member 30 is a member that is connected to the pair of first base members 10 or the pair of extended base members 20, as shown in FIGS. The second base member 30 comprises a second base main body 31, extension portions 32 attached to the side surfaces of both longitudinal ends of the second base main body 31 and extending outward in the longitudinal direction, and engagement protrusions 33 formed on the extended ends of the pair of extension portions 32 and engaging with the extended base member 20 (engagement hole portion 24) or the first base member 10 (engagement hole portion 12). A second key groove 58 is formed on the outer side of the engagement protrusion 33. The second key groove 58 is a slit-like groove into which the lock member 56 of the pillar member 40 is fitted.

[0027] The second base body 31 serves as a receiving portion for the construction member 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 upward beyond the second base body 31 . The engagement protrusion 33 protrudes laterally from the extension 32, and is detachably engaged with the engagement hole 24 (engagement hole 12) from the horizontal direction. Specifically, the engagement protrusion 33 has a U-shaped vertical cross section and includes a main body wall portion that protrudes from the extension portion 32 toward the extension base member 20, and a pair of reinforcing wall portions.

[0028] 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 main body 31 abuts against the side face of the extension base member 20, the side face of the extension portion 32 abuts against the end face of the extension base member 20, and the engagement protrusion portion 33 engages with the engagement hole portion 24. This makes it possible to increase the assembly rigidity of the loading rack 1 while eliminating the need for bolt fastening.

[0029] <Column members> As shown in Figures 1 to 4, the pillar members 40 are members that serve as supports for the loading rack 1, and are made of, for example, long bodies processed from square pipes. They are arranged at the four corners and the middle part of the loading rack 1, making a total of eight pillar members. Specifically, the pillar member 40 includes a pillar main body 41 having a rectangular cross section that is long in the vertical direction, an engaging protrusion 42 formed at the lower end of the pillar main body 41 and engaging with the first base member 10 (pillar engaging recess 16), a support protrusion 43 protruding from the inner side surface of the pillar main body 41, and a clamping portion 45 protruding from the outer side surface of the pillar main body 41. Convex locking members 51, 56 are formed on the inner side surface of the pillar main body 41, as shown in Figures 2 to 4. As shown in FIG. 6, the pillar member 40 is provided in the upper portion of the pillar main body 41, protrudes from the side of the pillar main body 41 in opposite directions, and has an engagement hole portion 46 and a second engagement hole portion 47 that engage with a connecting member 65 (engagement protrusion 67) or a receiving member 70 (second engagement protrusion 73). As shown in Figs. 7 and 8, the pillar member 40 is provided at the upper end of the pillar main body 41 and has an engagement hole portion 48 that engages with the roof member 90 (pillar engagement protrusion 93 of the shed member 91).

[0030] As shown in FIGS. 3 and 4, the engaging protrusion 42 has a closed cross section (rectangular cross section). The support projection 43 projects from the inner surface of the engaging protrusion 42 and extends in the vertical direction. The pillar member 40 is assembled to the first base member 10 (leg portion 15) in the up-down direction by fitting the engaging protrusion 42 into the pillar engaging recess 16. At this time, the support protrusion 43 is inserted into the support groove 17 and held by the support groove 17. This makes it easier to position the column member 40 when assembling the column member 40 to the first base member 10. In addition, the rigidity of the first base member 10 and the column member 40 can be increased.

[0031] The clamping portion 45 is a bent pressing member protruding from the outer surface of the engaging protrusion 42 , and is formed on the opposite side to the supporting projection 43 . The clamping portion 45 can clamp the pillar engaging recess 16 of the first base member 10 between the clamping portion 45 and the engaging protrusion 42. Therefore, the pillar member 40 can be firmly attached to the first base member 10.

[0032] 6, the fitting hole 46 and the second fitting hole 47 are formed at intervals in the vertical direction and have a common fitting method. The fitting hole 46 and the second fitting hole 47 are also called fitting pockets. The fitting hole 46 is disposed on the inner surface of the pole member 40 in the longitudinal direction of the loading rack 1, and the second fitting hole 47 is disposed on the outer surface of the pole member 40. The fitting hole 46 fits into the connecting member 65 (fitting protrusion 67), and the second fitting hole 47 fits into the receiving member 70 (second fitting protrusion 73), but is not particularly limited thereto. For example, the fitting hole 46 may fit into the second fitting protrusion 73, and the second fitting hole 47 may fit into the fitting protrusion 67.

[0033] As shown in Figs. 7 and 8, the uppermost fitting holes 46, 47 are fitted with a connecting member 80 (fitting protrusion 82).

[0034] As shown in Figs. 7 and 8, the engagement hole 48 is formed in the upper end of the pillar member 40, and has a closed cross-sectional (rectangular cross-sectional) structure. The engagement hole portion 48 is detachably engaged with the shed member 91 (pillar engagement protrusion 93) in the up-down direction. Specifically, the engagement hole portion 48 has a pair of upper wall portions 48a which form the left and right upper surfaces of the pillar member 40, a pair of first inner wall portions 48b and a pair of second inner wall portions 48c which are respectively formed inside the pillar member 40, and a bottom wall portion 48d which connects the lower ends of the first inner wall portions 48b and the second inner wall portions 48c. The bottom wall portion 48d has an insertion hole 48e formed therein for inserting the tip end of the shed member 91 (pillar engagement protrusion 93) therethrough.

[0035] 7 and 8, the above-mentioned configuration allows the engagement hole 48 to engage with the pillar engagement protrusion 93 of the shed member 91 so as to surround it. Therefore, the pillar member 40 and the roof member 90 can be connected without the need for bolt fastening.

[0036] <Holding member, second holding member> The holding member 50 is a member that maintains an engaged state when the extension base member 20 (engagement protrusion 22) is engaged with the first base member 10 (engagement hole portion 12) in the horizontal direction, as shown in Figures 3 and 4. More specifically, the holding member 50 is provided at the connecting portion between the first base member 10 and the extension base member 20, and holds the engaged state in the engaging direction (the length direction of the loading rack 1) and in the up-down direction. The retaining member 50 has a convex-shaped locking member 51 provided on the lower end of the pillar member 40, a key groove 52 formed in the engagement hole portion 12 of the first base member 10, and a second key groove 53 formed in the engagement protrusion portion 22 of the extension base member 20.

[0037] The locking member 51 is formed adjacent to the support projection 43 and protrudes outward beyond the support projection 43 . The locking member 51 fits into both the overlapping key groove 52 and the second key groove 53, thereby engaging and locking the first base member 10, the extension base member 20, and the pillar member 40 together.

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

[0039] As shown in FIG. 2, the second holding member 55 is a member that holds the engaged state when the second base member 30 (engagement protrusion 33) is engaged with the extension base member 20 (engagement hole 24) in the horizontal direction. More specifically, the second holding 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 engaging direction (the length direction of the loading rack 1) and in the up-down direction. The second holding member 55 has a similar structure to the holding member 50.

[0040] The second retaining member 55 has a convex-shaped locking member 56 provided on the lower end (engagement protrusion 42) of the pillar member 40, a key groove 57 formed in the engagement hole portion 24 of the extension base member 20, and a second key groove 58 formed in the engagement protrusion 33 of the second base member 30.

[0041] 2, the key groove 57 of the extension base member 20 and the second key groove 58 of the second base member 30 are arranged to overlap, and the lock member 56 fits into both the key groove 57 and the second key groove 58. In this way, the extension base member 20, the second base member 30, and the pillar member 40 are locked together. By configuring the locking member 56 and the key grooves 57, 58 in this way, the loading rack 1 can be assembled easily and firmly.

[0042] <Intermediate support member> As shown in Figures 1 and 5, the intermediate support member 60 is a member that is spanned between a pair of first base members 10, a pair of extended base members 20, or a pair of connecting members 65, 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 longitudinal ends of the support body 61 and clamping the base body 11 (base body 21, connecting body 66), and a fixing convex portion 63 provided on the inner surface of the mounting portion 62 and protruding 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 66) from above, and clamps the base body 11 so as to surround it. The fixing protrusion 63 protrudes downward from the bottom surface of the attachment portion 62 and is detachably fixed to a fixing hole 13 provided in the upper surface of the base body 11 .

[0044] As described above, by providing the intermediate support member 60 with the mounting portion 62 and the fixing protrusion 63, the assembly rigidity of the loading rack 1 can be increased while eliminating the need for bolt fastening. Furthermore, the intermediate support member 60 is assembled to the first base member 10 (the extension base member 20, the connecting member 65) in a state in which movement of the intermediate support member 60 in the horizontal direction is restricted. Therefore, the intermediate support member 60 allows the construction member 2 to be loaded more stably.

[0045] <Connecting parts, receiving parts> The connecting members 65, as shown in FIGS. 1 and 6, are members that connect the pillar members 40 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 65 has a long connecting body 66 and fitting protrusions 67 formed on both ends of the connecting body 66 in the longitudinal direction and fitting into the pillar member 40 (fitting hole portion 46). The fitting protrusion 67 is attached to an end face in the longitudinal direction of the connecting body 66, protrudes downward from the connecting body 66, and detachably fits from above into the fitting hole 46. In other words, the fitting protrusion 67 fits into the fitting hole 46 by a wedge method.

[0046] In the above configuration, as shown in FIG. 6, when the connecting member 65 is assembled to the pillar member 40, the end face of the fitting protrusion 67 abuts against the side face of the pillar member 40, and the fitting protrusion 67 is fitted into the fitting hole portion 46. By doing so, the assembly rigidity of the loading rack 1 can be increased while eliminating the need for bolt fastening (while achieving a boltless structure).

[0047] As shown in Figures 1 and 6, the support member 70 is a member that connects the column members 40 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 receiving member 70 has a long receiving body 71, extension portions 72 attached to the side surfaces of both longitudinal ends of the receiving body 71 and extending outward in the longitudinal direction, and second mating protrusions 73 formed on the respective extending ends of the pair of extension portions 72 and adapted to fit into the pillar member 40 (second mating hole portions 47). The second fitting protrusion 73 fits into the second fitting hole 47 by a wedge method.

[0048] In the above configuration, as shown in FIG. 6, when the receiving member 70 is assembled to the pillar member 40, the end face in the longitudinal direction of the receiving body 71 abuts against the side face of the pillar member 40, the extension portion 72 abuts against the outer surface of the pillar member 40, and the second fitting protrusion portion 73 is fitted into the second fitting hole portion 47. This makes it possible to increase the assembly rigidity of the loading rack 1 while eliminating the need for bolt fastening.

[0049] In the above configuration, as shown in FIG. 6, the connecting member 65 (fitting protrusion 67) fits into the pillar member 40 (fitting hole portion 46), and the receiving member 70 (second fitting protrusion 73) fits into the pillar member 40 (second fitting hole portion 47). The pillar member 40 is surrounded by the connecting member 65, the receiving member 70 (the receiving body 71), and the extending portion 72. By doing so, the assembly rigidity of the loading rack 1 can be increased while avoiding interference between the connecting member 65 and the receiving member 70.

[0050] <Connecting material> As shown in Figs. 1, 7 and 8, the connecting members 80 are members that function to connect the upper ends of the pillar members 40 together and to which the roof member 91 is additionally attached. The connecting member 80 has a similar shape to the connecting member 65 . There are two types of connecting members 80: a first connecting member 80A which is arranged at both ends of the length of the loading rack 1 and does not have an engagement hole 83, and a second connecting member 80B which is arranged in the center of the length of the loading rack 1 and has an engagement hole 83.

[0051] The connecting member 80 has a connecting body 81 that is long in the longitudinal direction of the loading rack 1, and a mating protrusion 82 that is attached to both longitudinal ends of the connecting body 81 and fits into the mating hole portions 46, 47 at the upper end of the pillar member 40. Further, an engagement hole 83 is formed on the upper surface of the second connecting member 80B, with which the shed member 91 (pillar engagement protrusion 93) is detachably engaged in the up-down direction.

[0052] The fitting protrusions 82 are attached to the end faces of the connector body 81 in the longitudinal direction, protrude downward from the connector body 81, and detachably fit from above into the fitting holes 46, 47. In other words, the fitting protrusions 82 fit into the fitting holes 46, 47 by a wedge method. As shown in FIG. 7, when the connecting member 80 is connected to the upper end of the pillar member 40, the upper surface of the connecting member 80 and the upper surface of the pillar member 40 are substantially flush with each other.

[0053] The engagement hole 83 has the same engagement method as the engagement hole 48 of the pillar member 40 . The engagement hole portion 48 can be engaged so as to surround the pillar engagement protrusion 93 of the shed member 91. This eliminates the need for bolt fastening.

[0054] <Roofing components (shed components, ridge components)> As shown in Figures 1 and 7 to 9, the roof members 90 are arranged at intervals along the length of the loading rack 1 and include roof members 91 which form the roof shed, and a ridge member 96 which forms the top part (ridge) of the roof, extends along the length of the loading rack 1, and is attached to the upper ends of the multiple roof members 91. In this embodiment, the roof member 90 is composed of five roof members 91 and four ridge members 96.

[0055] There are two types of shed members 91: a first shed member 91A which is arranged at both ends of the loading rack 1 in the longitudinal direction and has one engagement hole portion 95, and a second shed member 91B which is arranged in the central portion of the loading rack 1 in the longitudinal direction and has two engagement holes 95. The first roof member 91A and the second roof member 91B are arranged side by side with a gap therebetween. In this embodiment, the first roof member 91A is detachably engaged with the upper end of the pillar member 40 in the vertical direction, and the second roof member 91B located in the central position is detachably engaged with the upper end of the connecting member 80 in the vertical direction.

[0056] The first shed member 91A includes a shed body 92 that is elongated in the width direction of the loading rack 1, a column engagement protrusion 93 formed at both ends of the shed body 92 in the longitudinal direction and extending downward from the shed body 92, It has an engagement hole portion 95 provided at the upper end of the shed body 92 and attached via a bracket 94A. The second shed member 91B has a shed main body 92 that is elongated in the width direction of the loading rack 1, pillar engagement protrusions 93 formed on both longitudinal ends of the shed main body 92, and a pair of engagement holes 95 provided on the upper end of the shed main body 92 and attached via brackets 94B.

[0057] 7, the shed body 92 is made of a metal pipe material and is formed to have an inverted V shape. Specifically, the shed body 92 extends from its upper end while sloping downward so as to move away from each other. 8, the pillar engagement protrusion 93 is a circular pipe material formed to be narrower than the shed body 92. A step portion 93a is formed in the portion between the extending end of the shed body 92 and the pillar engagement protrusion 93. In the above configuration, the shed member 91 is attached to the pillar member 40 (connecting member 80) by the step portion 93a abutting the upper surface of the pillar member 40 (connecting member 80) and the pillar engagement protrusion 93 being inserted into the engagement hole portion 48 (83) formed in the upper surface of the pillar member 40 (connecting member 80). As a result, the assembly rigidity of the roof member 90 can be increased while eliminating the need for bolt fastening.

[0058] 9, the engagement hole 95 of the first roof member 91A is attached to the upper end of the roof body 92 via an L-shaped bracket 94A and fixed to the inner surface of the bracket 94A. A reinforcing plate 94Aa is attached diagonally to the inner surface of the L-shaped bracket 94A. The engagement hole portion 95 of the second shed member 91B is attached to the upper end portion of the shed main body 92 via a U-shaped bracket 94B and is fixed to both side surfaces of the bracket 94B.

[0059] As shown in FIG. 9, the ridge member 96 is a metal pipe member extending in the longitudinal direction of the loading rack 1, and is a member that connects the upper ends of the roof members 91 to each other. Specifically, the ridge member 96 has a ridge body 97 that is elongated in the longitudinal direction of the loading rack 1, and a shed engagement protrusion 98 that is attached to both longitudinal ends of the ridge body 97 and removably engages with the engagement hole portion 95 of the shed member 91 in the vertical direction.

[0060] As shown in Figure 9, when the ridge member 96 is assembled to the shed member 91, the longitudinal end face of the ridge body 97 abuts against the side of the shed member 91 (brackets 94A, 94B), and the shed engagement protrusion 98 engages with the engagement hole portion 95. This makes it possible to increase the assembly rigidity of the loading rack 1 while eliminating the need for bolt fastening. When the ridge member 96 is attached to the roof member 91, the upper surface of the ridge member 96 and the upper surface of the roof member 91 become substantially flush with each other.

[0061] <Rack cover> As shown in FIGS. 10 and 11, the rack cover 100 is a sheet-like cover that covers the entire body of the loading rack 1 from above. At both end faces in the length direction of the rack cover 100, opening / closing sections 101 for removing the building components 2 are formed. Similarly, at both end faces in the width direction of the rack cover 100, opening / closing sections 101 for removing the building components 2 are formed. With the above-mentioned configuration, a part of the rack cover 100 can be easily opened and closed as shown in Fig. 10. And, the construction member 2 can be easily removed from the covered loading rack 1.

[0062] In the above configuration, as shown in FIG. 11, by hooking the hoisting members L1 of the hoisting device L to the four sling hook portions 14 of the loading rack 1, the covered loading rack 1 can be hoisted. At this time, the roof members 91 (first roof members 91A) are provided at both ends in the length direction of the loading rack 1. The ridge member 96 is disposed in the center of the loading rack 1 in the width direction, and is disposed at the upper end of the loading rack 1. The connecting members 80 are disposed at both ends in the width direction of the loading rack 1. 11, when the loading rack 1 is lifted by the lifting device L, the lifting member L1 can be squeezed so as not to come into contact with the building member 2. Specifically, since the building member 2 is loaded so as to be surrounded by the connecting member 80 and the roof member 90, it is possible to prevent the lifting member L1 from coming into contact with the building member 2 when the lifting member L1 is squeezed.

[0063] In the above configuration, as shown in FIGS. 10 and 11, the rack cover 100 is supported by the shed member 91, the ridge member 96 and the connecting members 80 and covers the rack body. Therefore, the occurrence of bending or wrinkling in the rack cover 100 can be suppressed. In addition, the rack cover 100 may be provided with an opening / closing section for exposing the sling hook section 14 to the outside at a portion thereof corresponding to the sling hook section 14. This can further prevent the rack cover 100 from sagging or wrinkling.

[0064] The loading rack 1 can be assembled more easily than before, and the building materials 2 can be suitably transported and stored. Furthermore, the loading rack 1 can be suitably lifted by the lifting device L. For example, when lifting by the lifting device L, the lifting member L1 can be prevented from being squeezed and coming into contact with the building materials 2. In addition, by providing an extension base member 20, the overall length of the loading rack 1 can be extended so that construction components 2 of various shapes and sizes can be loaded.

[0065] <Other embodiments> In the above embodiment, as shown in Figure 1, the loading rack 1 is composed of two first base members 10, four extended base members 20, two second base members 30, eight pillar members 40, six intermediate support members 60, six connecting members 65, two support members 70, six connecting members 80, and roof members 90 (five shed members and four ridge members), but the number of parts of each component is not particularly limited and can be changed. For example, in order to increase the rigidity of the loading rack 1 and to suitably load the construction components 2, the number of intermediate support members 60 may be increased. Alternatively, the height of the loading rack 1 may be increased by arranging and connecting the pillar members 40 in the vertical direction. In this case, it is preferable to prepare pillar members 40 of different heights.

[0066] In the above embodiment, as shown in FIG. 1, the intermediate support member 60 is spanned across a pair of first base members 10 (a pair of connecting members 65), but this is not particularly limited and the intermediate support member 60 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 FIG. 7, the shed member 91 extends in the width direction of the loading rack 1, but this is not particularly limited, and the shed member 91 may extend in the length direction of the loading rack 1. In this case, it is preferable that the ridge member 96 extends in the width direction of the loading rack 1 to connect the shed members 91 to each other.

[0068] In the above embodiment, as shown in FIG. 7, the shed member 91 connects the pillar members 40 to each other and also connects the connecting members 80 to each other, but this is not particularly limited. For example, the shed members 91 may connect only the pillar members 40 together, or may connect only the connecting members 80 together.

[0069] In the above embodiment, as shown in Fig. 7, the shed member 91 has a convex pillar engaging protrusion 93 and the pillar member 40 has a concave engaging hole 48, but the convex-concave structure may be reversed. In other words, the shed member 91 may have a concave pillar engaging portion and the pillar member 40 may have a convex engaged portion. Similarly, the ridge member 96 has a convex shed engagement protrusion 98 and the shed member 91 has a concave engagement hole portion 95, but the concave-convex structure may be reversed. Alternatively, the engagement method is not limited to the concave-convex structure, and may be any type as long as the structures are detachably engageable with each other (eg, a hook-shaped structure).

[0070] In the above embodiment, the loading rack according to the present invention has 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]
