Description

[Technical field]

[0001] The present invention relates to a loading rack, and more particularly to a loading rack for loading a plurality of construction components at intervals in the vertical direction. [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 other vehicle installed at the construction site and stored there. The loading racks are then returned to the factory. [Prior art documents] [Patent documents]

[0003] [Patent Document 1] JP 2016-089567 A [Patent Document 2] JP 2018-104040 A Summary of the Invention [Problem to be solved by the invention]

[0004] Incidentally, the loading racks as disclosed in Patent Documents 1 and 2 are composed of loading units that can be combined vertically. Specifically, the loading units can be combined vertically by installing a cup-shaped leg portion formed on the lower end of one loading unit on the upper end of the other loading unit. Normally, loading racks are used by being installed on the floor, the bed of a truck, or on a cross beam. However, conventional loading racks have legs that taper downward, so there is a risk that the loading rack may become unstable when the legs are installed on a mounting surface such as a cross beam.

[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 improve stability when the loading rack is installed on an installation surface. [Means for solving the problem]

[0006] The above problem is solved by the loading rack of the present invention, which is a loading rack capable of loading multiple building components with spaces between them in the vertical direction, and which includes a base member that serves as the base of the loading rack, and the base member has legs that support the main body of the base member from below, and the legs have a pair of first wall portions that protrude downwardly at a space from a lower end of the main body of the base member, a pair of second wall portions that extend horizontally outward from the protruding ends of the pair of first wall portions, and a pair of third wall portions that protrude downwardly from the extending ends of the pair of second wall portions and are positioned at a greater distance than the pair of first wall portions. With the above configuration, the legs of the base member that serves as the foundation of the loading rack are formed in a stepped shape by the first wall, the second wall, and the third wall. This improves the strength of the legs and the stability of the loading rack. In addition, the horizontally extending second wall is installed on the installation surface of a log or the like, thereby improving the stability of the loading rack.

[0007] In this case, the loading rack comprises a pair of base members spaced apart in the longitudinal direction of the building member, and a pair of connecting members connected to the upper ends of the pair of base members, the base members having the legs and a support portion provided above the legs and extending in the vertical direction, the connecting members having a connecting mounting portion extending in the width direction of the building member for placing the building member on it, and connecting support portions provided at both ends in the extension direction of the connecting mounting portion and extending in the vertical direction, and the connecting support portions are removably engaged with the upper ends of the support portions. With the above-mentioned configuration, the loading rack can be detachably assembled using the base member and the connecting member. Therefore, when the loading rack is not in use, the base member and the connecting member can be disassembled to save storage space.

[0008] In this case, it is preferable that the pair of first wall portions and the pair of third wall portions are formed so that the distance between them increases downward. With the above-mentioned configuration, the legs are formed in a cup shape, which further improves the stability of the loading rack.

[0009] In this case, the leg portion has a pair of fourth wall portions extending horizontally outward from the lower ends of the pair of third wall portions, and ribs protruding from the outer surfaces of each of the first wall portion, the second wall portion, the third wall portion and the fourth wall portion, and the ribs preferably extend continuously from the first wall portion to the fourth wall portion. With the above-described configuration, the rigidity of the legs can be increased, and the stability of the loading rack can be further improved.

[0010] In this case, the loading rack is arranged between the base member and the connecting member in the vertical direction and is provided with an adjustment member for adjusting the height of the loading rack, the support portion of the base member has a main body portion extending in the vertical direction and an engagement portion formed at the upper end of the main body portion, the connecting support portion of the connecting member has a connecting main body portion extending in the vertical direction and an engaged portion formed at the lower end of the connecting main body portion and engaged with the engaging portion, the adjustment member is attached to the upper end of the main body portion and has a ring-shaped portion surrounding the engaging portion, and the engaging portion engages with the engaged portion when the ring-shaped portion is attached to the engaging portion. With the above-described configuration, the height position of the loading rack can be easily adjusted by the adjustment member, so that construction components of various sizes can be placed on it.

[0011] In this case, the loading rack comprises a first loading unit which loads multiple building components at intervals in the vertical direction, and a second loading unit which is provided above the first loading unit and loads multiple building components at intervals in the vertical direction, the second loading unit comprising the pair of base members and the pair of connecting members, and the first loading unit comprising the pair of base members, the pair of connecting members, and a pair of support members which are respectively connected to the upper ends of the pair of connecting members and support the pair of base members of the second loading unit from below. With the above-mentioned configuration, the loading units can be easily stacked by mounting the legs of the base member of the second loading unit on the receiving member of the first loading unit, and the stability of the loading rack can be improved.

[0012] In this case, the support portion of the first loading unit has a first main body portion extending in the vertical direction and an engagement portion formed at the upper end of the first main body portion, the support portion of the second loading unit has a second main body portion extending in the vertical direction and an engaged support portion formed at the lower end of the second main body portion and engaged with the engagement portion, the leg portion has an attachment portion attached to the support portion, and a notch portion is formed in the attachment portion communicating with the engaged support portion, and the engagement portion is capable of engaging with the engaged support portion through the notch portion. With the above-described configuration, when the base member of the first loading unit and the base member of the second loading unit are stored in a stacked state, the base members can be easily stacked, thereby making it possible to make the storage space of the loading rack compact. Effect of the Invention

[0013] According to the loading rack of the present invention, the stability can be improved when the loading rack is installed on an installation surface. [Brief description of the drawings]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0015] Hereinafter, an embodiment of the present invention will be described with reference to FIGS. This embodiment relates to a loading rack that loads multiple building components with spaces between them in the vertical direction, and that can improve stability when the loading rack is installed on an installation surface. In the following description, as shown in Figures 1 and 2, the "up-down direction" refers to the up-down direction when the building materials are placed on the loading rack. The "front-rear direction" refers to the width direction of the loading rack and the building materials, and refers to the front-rear direction when the loading rack is viewed from the front. The "left-right direction" refers to the length direction of the loading rack and the building materials, and refers to the left-right direction when the loading rack is viewed from the front. The "left-right direction" is a direction perpendicular to the "up-down direction" and "front-rear direction".

[0016] <Overall configuration of loading rack> 1, the loading rack 1 of this embodiment is a rack capable of transporting a plurality of plate-shaped building components P loaded thereon. For example, the loading rack 1 is used to stack the building components P flat in a factory and transport the building components P in a stacked state from the factory to a construction site by truck. The loading rack 1 is also called a procurement logistics rack, a transport rack (current delivery rack), a storage rack (wood rack), etc. depending on the purpose of use. The loading rack 1 may be used commonly for each purpose, or may be used specifically for each purpose.

[0017] The building materials P are plate-like members 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 members, etc. The building materials P are also called currently delivered items. When architectural panels are loaded as the building components P, 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.

[0018] As shown in FIG. 1, the loading rack 1 includes a first loading unit U1 capable of loading multiple building components P at intervals in the vertical direction, and a second loading unit U2 disposed above the first loading unit U1 and loading multiple building components P at intervals in the vertical direction. Specifically, the first loading unit U1 can load six building components P with vertical spacing, and the second loading unit U2 can load four building components P with vertical spacing.

[0019] The number of building components P loaded in the first loading unit U1 and the second loading unit U2 can be changed as appropriate. For example, it can be changed according to the loading amount of the building components P. Further, the loading rack 1 is configured such that the second loading unit U2 is stacked one on top of the first loading unit U1, but the number of stacked loading units can be changed as appropriate.

[0020] As shown in Figures 1 and 2, the first loading unit U1 mainly comprises a pair of base members 10 that form the foundation of the loading rack 1, a pair of connecting members 20 connected to the upper ends of the pair of base members 10, and a pair of receiving members 30 connected to the upper ends of the pair of connecting members 20. The pair of base members 10, the pair of connecting members 20, and the pair of receiving members 30 are provided at a predetermined interval in the length direction of the building member P (that is, the left-right direction).

[0021] In addition, the first loading unit U1 is provided with a plurality of connecting members 40 extending in the longitudinal direction (i.e., left-right direction) of the loading rack 1 and respectively connecting a pair of base members 10, a pair of connecting members 20, and a pair of receiving members 30, and a plurality of adjustment members 50 for adjusting the height of the loading rack 1. The second loading unit U2 has the same configuration as the first loading unit U1, and therefore the description thereof will be omitted.

[0022] 1, when the loading rack 1 is in use, the first loading unit U1 has a configuration in which five pairs of connecting members 20 are stacked on a pair of base members 10, and a pair of receiving members 30 are stacked on top of the five pairs of connecting members 20. The second loading unit U2 has a configuration in which three pairs of connecting members 20 are stacked on top of the pair of base members 10, and a pair of receiving members 30 are stacked on top of the three pairs of connecting members 20. The number of pairs of connecting members 20 stacked on top of each other can be changed as appropriate.

[0023] In the loading rack 1 of this embodiment, each component is detachable from the other. When the loading rack 1 is in use, each component is assembled, so that the building components P can be loaded onto the loading rack 1. When not in use (when storing), the loading rack 1 is disassembled, so that each component can be collected together. Therefore, as shown in Fig. 6, the base member 10 of the first loading unit U1 and the base member 10 of the second loading unit U2 can be stacked during storage in the loading rack 1, and can be collected together. Also, as shown in Fig. 7, the receiving member 30 of the first loading unit U1 and the receiving member 30 of the second loading unit U2 can be stacked during storage in the loading rack 1, and can be collected together. Incidentally, the linking members 20, the connecting members 40, and the adjusting members 50 can also be collected together as components when the loading rack 1 is stored.

[0024] <Base material> 1 to 5, the base member 10 is a member that serves as the foundation of the loading rack 1, and is installed on an installation surface such as a floor or a log. The base member 10 has a mounting portion 11 for mounting a building member P, a support portion 12 extending in the vertical direction, and legs 13 that support the mounting portion 11 and the support portion 12 from below. In addition, if the loading rack 1 is configured to be capable of stacking a plurality of building members P, the base member 10 may not have the placement portion 11. For example, the base member 10 may have only the legs 13 installed on the installation surface and the support portions 12 provided above the legs 13.

[0025] 2 and 3, the placement portion 11 is a member for placing the building component P, and extends in the width direction (i.e., the front-rear direction) of the building component P. The placement portion 11 is made of a long body, for example, a processed square pipe, and the upper surface becomes the placement surface on which the building component P is placed. Support parts 12 are attached to both ends in the front-rear direction of mounting part 11. Spacers 11a for mounting legs 13 are attached to the lower surfaces of both ends in the front-rear direction of mounting part 11.

[0026] 2 and 3, the support pillars 12 extend in the vertical direction and serve as supports for the loading rack 1 as a whole, and are disposed at the four corners of the loading rack 1. The support pillars 12 are provided above the legs 13 and detachably engage with the lower ends of the connecting members 20. 3 to 5, the support parts 12 are provided at both ends in the extending direction (i.e., the front-rear direction) of the mounting part 11. The support parts 12 have a hollow main body part 12a that is long in the vertical direction, an engaging protrusion part 12b formed at the upper end part of the main body part 12a, and a recess part 12c formed at the lower end part of the main body part 12a.

[0027] The main body 12a is a main body portion of the support 12, and has a generally rectangular cross section in top view. A fixing portion 12d for fixing the connection member 40 is formed on the outer surface of the main body 12a in the front-rear direction. The engaging protrusion 12b is an engaging portion that detachably engages with the lower end of the connecting member 20 and has a substantially U-shaped cross section in a top view. The engaging protrusion 12b protrudes upward from the upper end of the main body portion 12a. The engaging protrusion 12b is disposed inside the main body portion 12a in a top view. Since the engaging protrusion 12b has a generally U-shaped cross section, the inside of the hollow main body 12a communicates with the inside of the engaging protrusion 12b.

[0028] The recess 12c is an engaged support portion that is detachably engaged with the engaging protrusion 12b, and is a lower end portion of the main body portion 12a. As shown in Fig. 6, when a plurality of base members 10 are stacked on top of each other in the vertical direction, the recess 12c of one base member 10 is detachably engaged with the engaging protrusion 12b of the other base member 10. In this embodiment, the recess 12c is the lower end portion of the hollow cylindrical main body portion 12a, but if the main body portion 12a is a solid pillar member, it may be a hole portion formed in the lower end surface of the main body portion 12a.

[0029] 3 to 5, the legs 13 are support legs for placing the main body of the base member 10 (specifically, the placement part 11 and the support part 12) on a floor installation surface F or a wooden installation surface S, and are attached to the lower ends of the placement part 11 and the support part 12. It is sufficient that the legs 13 are attached to at least one of the placement part 11 and the support part 12.

[0030] The leg portion 13 has an attachment portion 13a attached to the support portion 11 and the support portion 12, a pair of first wall portions 13b protruding downward with a gap therebetween, a pair of second wall portions 13c extending outward from the first wall portions 13b, a pair of third wall portions 13d protruding downward with a gap therebetween from the second wall portions 13c, a pair of fourth wall portions 13e extending outward from the extended ends of the third wall portions 13d, and ribs 13f and reinforcing ribs 13g protruding from the outer surfaces of the attachment portion 13a, the first wall portion 13b, the second wall portion 13c, the third wall portion 13d, and the fourth wall portion 13e. The leg portion 13 is formed in a stepped shape by an attachment portion 13a, a first wall portion 13b, a second wall portion 13c, a third wall portion 13d, and a fourth wall portion 13e.

[0031] The attachment portion 13a is a plate-like member attached to the mounting portion 11 and the support portion 12. Note that it is sufficient that the attachment portion 13a is attached to at least one of the mounting portion 11 and the support portion 12 from below. The mounting portion 13a is formed with a notch 13aa that communicates with the recess 12c. Specifically, the mounting portion 13a is cut out at a portion that corresponds to the main body portion 12a.

[0032] 6, when the base members 10 are stacked one on top of the other in the vertical direction, the engaging protrusion 12b of one base member 10 is configured to be insertable into the recess 12c of the other base member 10 through the cutout portion 13aa. Specifically, the engaging protrusion 12b provided on the main body portion 12a (corresponding to the first main body portion) of the first stacking unit U1 is capable of engaging with the recess 12c provided on the main body portion 12a (corresponding to the second main body portion) through the cutout portion 13aa of the second stacking unit U2. In this way, since the mounting portion 13a has the notch portion 13aa, when the base members 10 are separated and the loading rack 1 is not in use (when stored), the base members 10 can be stacked on top of each other. Therefore, when the loading rack 1 is stored, the storage space of the loading rack 1 can be made compact.

[0033] The first wall portions 13b are plate-like members provided continuously from the left and right ends of the mounting portion 13a. The pair of first wall portions 13b protrude downward with a gap therebetween from the lower end of the main body of the base member 10. Specifically, the pair of first wall portions 13b protrude downward from the left and right ends of the mounting portion 13a attached to the lower ends of the placement portion 11 and the support portion 12, and are formed so that the distance between them increases as they go downward.

[0034] The second wall portion 13c is a plate-like member that is provided continuously from the lower end (protruding end) of the first wall portion 13b. The pair of second wall portions 13c extend horizontally outward from the protruding ends of the pair of first wall portions 13b. As shown in FIG. 4, the lower surface of the horizontally extending second wall portion 13c abuts against the lashing installation surface S, and the loading rack 1 is installed.

[0035] The third wall portion 13d is a plate-like member provided continuously from the extending end portion of the second wall portion 13c. The pair of third wall portions 13d protrude downward from the extending end portions of the pair of second wall portions 13c, respectively, and are disposed farther apart than the pair of first wall portions 13b. Specifically, the pair of third wall portions 13d protrude downward from the extending end portions of the pair of second wall portions 13c, respectively, and are formed so that the distance between them increases as they go downward.

[0036] 4, the left-right width W2 at the upper ends of the pair of third walls 13d is greater than the left-right width W1 at the lower ends of the pair of first walls 13b. The leg 13 is formed with a second wall 13c extending horizontally relative to the link installation surface S. Generally, a 90 mm wide or 100 mm wide timber is used as a timber for installing the loading rack 1. The left-right width W1 at the lower end of the pair of first walls 13b is narrower than the width of a 90 mm wide timber (shown by a two-dot chain line in FIG. 4). The left-right width W2 at the upper end of the pair of third walls 13d is wider than the width of a 100 mm wide timber (not shown). The legs 13 are configured so that the underside of the second wall portion 13c can abut against the link installation surface S and a gap is provided between the third wall portion 13d and the link, thereby allowing the loading rack 1 to be stably installed on two types of link.

[0037] The fourth wall portion 13e is a plate-like member provided continuously from the lower end portion (lower end portion) of the third wall portion 13d. The pair of fourth wall portions 13e extend horizontally outward from the lower ends of the pair of third wall portions 13d, respectively. 1, the lower surface of the horizontally extending fourth wall portion 13e is placed on the floor installation surface F. When the loading rack 1 is placed on the substantially horizontal floor installation surface F, the formation of the fourth wall portion 13e increases the area of ​​contact between the leg portion 13 and the floor installation surface F. Therefore, even if the weight of the main body of the base member 10, the connecting member 20, and the receiving member 30 is applied to the leg portion 13, the reaction force applied from the floor installation surface F to the leg portion 13 can be dispersed, and damage to the leg portion 13 can be suppressed.

[0038] The rib 13f extends continuously from the first wall portion 13b to the fourth wall portion 13e. Specifically, the rib 13f is formed so as to protrude from both side surfaces in the left-right direction of the main body portion 12a, the upper surface of the attachment portion 13a, the surface opposite to the opposing surfaces of the pair of first wall portions 13b, the upper surface of the second wall portion 13c, the surface opposite to the opposing surfaces of the pair of third wall portions 13d, and the upper surfaces of the pair of fourth wall portions 13e. The reinforcing ribs 13g are formed to protrude from both left-right side surfaces of the spacer 11a of the mounting portion 11, from the upper surface of the mounting portion 13a, the surface opposite the opposing surfaces of the pair of first wall portions 13b, the upper surface of the second wall portion 13c, the surface opposite the opposing surfaces of the pair of third wall portions 13d, and the upper surfaces of the pair of fourth wall portions 13e.

[0039] The ribs 13f and the reinforcing ribs 13g are formed continuously with the stepped wall portion, which further increases the rigidity of the leg portion 13. Also, the ribs 13f and the reinforcing ribs 13g are formed to be aligned at predetermined intervals in the front-rear direction, which further increases the rigidity of the leg portion 13. In addition, since the rigidity is increased by the ribs 13f and the reinforcing ribs 13g, it is possible to shorten the front-rear width (length in the front-rear direction) of the legs 13. Therefore, the components of the loading rack 1 can be made smaller, and weight and space can be reduced.

[0040] In this way, by forming the legs 13 in a stepped shape, it is possible to increase the rigidity and improve the stability of the loading rack 1. In addition, since the lower surface of the horizontally extending second wall portion 13c is placed on the link installation surface S, the stability of the loading rack 1 can be further improved. Furthermore, by making the legs 13 step-shaped to increase the rigidity, it is possible to shorten the front-to-rear width of the legs 13. Therefore, the components of the loading rack 1 can be made smaller, making it possible to reduce the weight and space required.

[0041] <Connecting parts> 1 to 3, a plurality of connecting members 20 are provided between the base member 10 and the receiving member 30 in the vertical direction. The connecting member 20 has a connecting placement portion 21 for placing the building member P thereon, and a connecting support portion 22 extending in the vertical direction. A plurality of connecting members 20 are provided in the vertical direction and are detachably engaged with the base member 10 and the receiving member 30. By detachably engaging the plurality of connecting members 20, the number of construction members P placed on the loading rack 1 can be adjusted.

[0042] 2 and 3, the connecting placement part 21 is a member for placing the building component P, and extends in the width direction (i.e., the front-rear direction) of the building component P. The connecting placement part 21 is made of a long body, for example, a processed square pipe, and the upper surface becomes the placement surface on which the building component P is placed. A connecting support portion 22 is attached to each of both ends of the connecting placement portion 21 in the front-rear direction.

[0043] 2 and 3, the connecting support parts 22 extend in the vertical direction and serve as supports for the loading rack 1 as a whole, and are disposed at the four corners of the loading rack 1. The connecting support parts 22 are detachably engaged with the upper end part of the base member 10 and the lower end part of the receiving member 30 to form the supports for the loading rack 1. 2 and 3, the connecting support parts 22 are provided on both ends in the extending direction (i.e., the front-rear direction) of the connecting mounting part 21. The connecting support parts 22 have a hollow connecting main body part 22a that is long in the up-down direction, a fitting convex part 22b formed at the upper end part of the connecting main body part 22a, and an engagement concave part 22c formed at the lower end part of the connecting main body part 22a.

[0044] The connecting body 22a is a main body of the connecting pillar 22 and has a generally rectangular cross section in top view. A connecting fixing portion 22d for fixing the connecting member 40 is formed on the outer surface of the connecting body 22a in the front-rear direction. The fitting protrusion 22b is a fitting portion that detachably fits with the lower end of the receiving member 30 or the connecting body portion 22a of the connecting support portion 22, and has a substantially U-shaped cross section in a top view. The fitting protrusion 22b protrudes upward from the upper end of the connecting body portion 22a. The fitting protrusion 22b is disposed inside the connecting body portion 22a in a top view. The engaging recess 22c is an engaged portion that is detachably engaged with the upper end portion of the base member 10 or the connecting body portion 22a of the connecting strut portion 22, and is a lower end portion of the connecting body portion 22a. As shown in Fig. 3, when a plurality of connecting members 20 are stacked on the base member 10, the engaging recess 22c of the connecting member 20 is detachably engaged with the engaging protrusion 12b of the base member 10 or the fitting protrusion 22b of the other connecting member 20. In this embodiment, the engagement recess 22c is the lower end portion of the hollow cylindrical connecting main body portion 22a, but in the case where the connecting main body portion 22a is a solid pillar member, it may be a hole portion formed in the lower end surface of the connecting main body portion 22a.

[0045] <Support material> 1 to 3, the receiving member 30 is a member that supports the base member 10 of the second loading unit U2 from below. The receiving member 30 has a receiving placement portion 31 for placing a building member P thereon, a receiving support portion 32 extending in the vertical direction, and a receiving portion 33 that supports the leg portion 13 of the base member 10 from below.

[0046] 1 to 3, the receiving placement portion 31 is a member for placing the building component P thereon, and extends in the width direction (i.e., the front-rear direction) of the building component P. The receiving placement portion 31 is made of a long body, for example, a processed square pipe. In Figs. 1 and 2, the building component P is not placed on the upper surface of the receiving placement portion 31, but the building component P may be placed on the upper surface of the receiving placement portion 31. A receiving support portion 32 is attached to each of both ends in the front-rear direction of the receiving placement portion 31. Further, a receiving spacer 31a for attaching a receiving portion 33 is attached to the upper surface of each of both ends in the front-rear direction of the receiving placement portion 31.

[0047] 1 to 3, the receiving support parts 32 extend in the vertical direction and serve as supports for the loading rack 1 as a whole, and are disposed at the four corners of the loading rack 1. The receiving support parts 32 are detachably engaged with the lower ends of the connecting members 20 to form the supports for the loading rack 1. 1 to 3, the receiving pillars 32 are provided at both ends in the extending direction (i.e., the front-rear direction) of the receiving placement part 31. The receiving pillars 32 have a hollow receiving body part 32a that is long in the vertical direction, a support part 32b formed at the upper end part of the receiving body part 32a, and a fitting recess 32c formed at the lower end part of the receiving body part 32a.

[0048] The receiving body portion 32a is a main body portion of the receiving column portion 32, and has a generally rectangular cross section in top view. A receiving fixing portion 32d for fixing the connecting member 40 is formed on the outer surface of the receiving body portion 32a in the front-rear direction. The support portion 32b is an elongated member that extends in the front-rear direction and supports the receiving portion 33 from below, and has a substantially rectangular cross section when viewed from the front. The support portion 32b is attached to the upper end surface of the receiving body portion 32a and the upper surface of the receiving spacer 31a.

[0049] The fitting recess 32c is a fitted portion that detachably fits with the fitting protrusion 22b of the connecting support portion 22, and is the lower end portion of the receiving body portion 32a. In this embodiment, the mating recess 32c is the lower end portion of the hollow cylindrical receiving body portion 32a, but in the case where the receiving body portion 32a is a solid pillar member, it may be a hole portion formed in the lower end surface of the receiving body portion 32a.

[0050] As shown in FIGS. 1 to 3, the receiving portion 33 is a portion that supports the leg portion 13 of the second loading unit U2 from below, and is attached to the upper surface of the support portion 32b. The receiving portion 33 has a contact portion 33a that contacts the leg portion 13, and a pair of receiving walls 33b that protrude upwardly with a space therebetween from the contact portion 33a.

[0051] The abutment portion 33a is a plate-like member attached to the support portion 32b. As shown in Fig. 1, the mounting portion 13a of the leg portion 13 of the second loading unit U2 abuts from above against the upper surface of the abutment portion 33a extending horizontally, thereby improving the stability of the loading rack 1.

[0052] The pair of receiving walls 33b protrude upward from the front and rear ends of the contact portion 33a, and are formed such that the distance between them increases as they extend upward. The receiving wall portion 33b is a plate-like member provided continuously from the front and rear ends of the contact portion 33a. The left-right width of the contact portion 33a and the receiving wall portion 33b is formed to be approximately the same as the left-right width of the receiving main body portion 32a and the support portion 32b.

[0053] The pair of first walls 13b and the pair of third walls 13d in the leg 13 of the second loading unit U2 are formed so that the distance between them increases toward the bottom. Therefore, the receiving wall 33b of the first loading unit U1 and the first and third walls 13b and 13d extend obliquely in a direction intersecting with each other based on the abutting portion 33a and the mounting portion 13a that abut against each other, thereby preventing mutual interference and mutual positional deviation. Therefore, the second loading unit U2 can be stably installed on the first loading unit U1.

[0054] 7, when a plurality of receiving members 30 are stacked on top of each other in the vertical direction, the receiving body portion 32a of one receiving member 30 is placed on the abutment portion 33a of the other receiving member 30. When a plurality of receiving members 30 are arranged side by side in the horizontal direction, they can be placed with almost no gap in the width direction of the receiving portion 33 (i.e., the horizontal direction). In this way, when the loading rack 1 is not in use (when stored), the receiving members 30 can be stacked side by side with almost no gap between them when the receiving members 30 are separated. Therefore, when the loading rack 1 is stored, the storage space of the loading rack 1 can be made compact.

[0055] In this way, the first loading unit U1 and the second loading unit U2 can be stacked by connecting the base member 10, the connecting member 20 and the receiving member 30 in the vertical direction by engaging the engaging portions and engaged portions, and the fitting portions and fitted portions, of the support portion 12, the connecting support portion 22 and the receiving support portion 32, respectively. In the present embodiment, the engaging portion is convex and the engaged portion is concave, but this is not limited thereto. For example, the engaging portion of the support portion 12 may be concave and the engaged portion of the connecting support portion 22 may be convex.

[0056] <Connection parts> 1 and 2, the connection members 40 are linking members that connect a pair of base members 10, a pair of connecting members 20, and a pair of receiving members 30 that are aligned in the left-right direction. The connection members 40 maintain a predetermined distance between the pair of base members 10, the pair of connecting members 20, and the pair of receiving members 30, and provide rigidity to the loading rack 1. The connecting member 40 has an extending portion 41 that extends in the length direction (left-right direction) of the loading rack 1, and fixed portions 42 that are provided at both ends of the extending portion 41 and are fixed to the support portions 12.

[0057] The extension portion 41 is a rod-shaped member that is long in the left-right direction and is made of, for example, a long body obtained by processing a square pipe. The extension portion 41 is disposed between the support portions 12 of the pair of base members 10. Fixed portions 42 are attached to both ends of the extension portion 41 in the left-right direction. The fixed portion 42 is, for example, a metal plate-like member, and is attached to the outer surface of the extending portion 41 in the front-rear direction. A plurality of fixing holes 42a are formed in the fixed portion 42 at a predetermined interval in the left-right direction. The fixing holes 42a and the fixing portion 12d of the support portion 12 are mated and bolted together, so that the connection member 40 is fixed to the outer surface of the support portion 12. The fixing holes 42a and the connecting and fixing portion 22d of the connecting support portion 22 are mated and bolted together, so that the connection member 40 is fixed to the outer surface of the connecting support portion 22. The fixing holes 42a and the receiving and fixing portion 32d of the receiving support portion 32 are mated and bolted together, so that the connection member 40 is fixed to the outer surface of the receiving support portion 32.

[0058] <Adjustment parts> 8 and 9, the adjustment member 50 is an attachment member for adjusting the height of the loading rack 1, and is detachably disposed in the vertical direction between the pair of base members 10 and the pair of connecting members 20. For example, when a building panel with a special height (thickness) is loaded onto the loading rack 1 as the building member P, the adjustment member 50 can be used to adjust the height of the resting surface to match the thickness of the special building panel. The adjustment member 50 is disposed between the pair of base members 10 and the pair of connecting members 20, but is not limited thereto, and may be disposed between the pair of connecting members 20. The adjustment member 50 may also be disposed between the pair of connecting members 20 and the pair of receiving members 30.

[0059] As shown in Figures 8 and 9, the adjustment member 50 is attached to the upper end of the main body portion 12a and has an annular portion 51 that surrounds the engaging protrusion 12b, a lower locking piece 52 that is inserted into the base member 10, and an upper locking piece 53 that is inserted into the connecting member 20. The adjustment member 50 connects the base member 10 and the connecting member 20 with a gap in the vertical direction by the annular portion 51, with the lower engagement piece 52 engaging with the support portion 12 of the base member 10 and the upper engagement piece 53 engaging with the connecting support portion 22 of the connecting member 20.

[0060] The annular portion 51 is a plate-like member having a substantially rectangular shape in a top view. The annular portion 51 is attached to the engaging protrusion 12b so as to surround the periphery of the engaging protrusion 12b, and abuts against the upper end surface of the main body portion 12a. When the annular portion 51 is attached to the engaging protrusion 12b, the engaging protrusion 12b is disposed inside the main body portion 12a in a top view, so that the outer surfaces of the annular portion 51 and the main body portion 12a are substantially flush with each other.

[0061] The length of the annular portion 51 in the up-down direction is formed to be shorter than the length of the engaging protrusion 12b. Therefore, when the annular portion 51 is attached to the engaging protrusion 12b of the base member 10, the engaging protrusion 12b can engage with the engaging recess 22c of the connecting member 20. In this way, even when the adjustment member 50 is disposed, the connecting member 20 can be stably connected to the base member 10. In addition, when the engaging portion of the support portion 12 is formed in a concave shape and the engaged portion of the connecting support portion 22 is formed in a convex shape, the annular portion 51 may be attached to the connecting support portion 22 so as to surround the periphery of the engaged portion of the connecting support portion 22.

[0062] The lower locking piece 52 is a plate-like member extending so as to protrude downward from the annular portion 51. The lower locking piece 52 is inserted into the inside of the main body portion 12a and locked to the support portion 12. The upper locking piece 53 is a plate-like member extending so as to protrude upward from the annular portion 51. The upper locking piece 53 is inserted into the inside of the connecting body portion 22a and locked to the connecting support portion 22.

[0063] By forming the lower locking piece 52 and the upper locking piece 53 on the annular portion 51, the connecting member 20 can be more stably connected to the base member 10 even when the adjustment member 50 is positioned between the base member 10 and the connecting member 20. In addition, in the vertical direction, the length of the lower locking piece 52 is formed to be longer than the length of the upper locking piece 53. By making the lower locking piece 52 longer, the connecting member 20 can be connected to the base member 10 more stably.

[0064] In this way, since the adjustment member 50 is disposed between the pair of base members 10 and the pair of connecting members 20, the position in the vertical direction can be finely adjusted by the height of the annular portion 51. Therefore, the height can be easily changed to suit a special building panel without changing the component sizes of the base member 10 and the connecting member 20.

[0065] With the above configuration, the legs 13 are formed in a stepped shape, which increases the rigidity and improves the stability of the loading rack 1. In addition, the lower surface of the horizontally extending second wall portion 13c is placed on the link installation surface S, which further improves the stability of the loading rack 1. Furthermore, by making each component of the loading rack 1 detachable, the components can be disassembled and stored together when the loading rack 1 is not in use. Furthermore, by engaging the respective components in the vertical direction, the loading rack 1 can be easily and firmly assembled. Also, by standardizing the components of the loading rack 1, the production cost can be reduced.

[0066] 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]
