Description

[Technical field]

[0001] The present invention relates to a loading rack, and more particularly to a loading rack that can be transported while being loaded with construction members. [Background technology]

[0002] 2. Description of the Related Art Conventionally, there has been known a loading rack capable of loading building panels and wooden construction members manufactured in a factory in order to transport these building panels and construction members (see, for example, Patent Document 1). 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 2016-088607 A Summary of the Invention [Problem to be solved by the invention]

[0004] Incidentally, the loading rack as described in Patent Document 1 is equipped with an engagement member (positioning member) for holding the horizontal position of an exterior wall panel (construction member). The engagement member is detachably attached to a panel receiving member (support member) on which the exterior wall panel is placed, and engages with the exterior wall panel. A cushioning material is attached to the engagement member to prevent damage to the exterior wall panel.

[0005] Conventionally, when an exterior wall panel is placed on a panel support, the cushioning material arranged between the engagement member and the exterior wall panel may adhere excessively to the exterior wall panel. If the engagement member and the exterior wall panel adhere to each other via the cushioning material, there is a risk that the engagement member may come off the panel support when the exterior wall panel is removed from the loading rack. This may result in a worker having to remove the engagement member from the exterior wall panel, which may reduce work efficiency. In addition, when the exterior wall panel was lowered from the loading rack, the engaging member was lifted up together with the exterior wall panel while remaining in close contact with the exterior wall panel via the cushioning material, which created the risk of the engaging member falling from the exterior wall panel.

[0006] 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 workability and safety when transporting building components. [Means for solving the problem]

[0007] The above problem is solved by the loading rack of the present invention, which is a loading rack that can be transported while loaded with building materials, and which comprises a plurality of pillar members extending in the vertical direction, a support member extending in the horizontal direction and spanned across the plurality of pillar members for supporting the building materials, and a positioning member that is detachably attached to the support surface of the support member and determines the position of the building material supported by the support member, wherein the positioning member has an attachment portion attached to the placement member, a positioning portion provided on the attachment portion for positioning the building material, a cushioning material provided on the attachment portion and disposed between the attachment portion and the building material, and a biasing member provided on the attachment portion for biasing the building material toward the building material or biasing the cushioning material toward the attachment portion, and the biasing member biases the building material or the cushioning material while the building material is supported by the support member and positioned by the positioning portion. With the above-mentioned configuration, the biasing member prevents the cushioning material and the construction material from coming into close contact with each other, so that the positioning member is prevented from coming off the support member when the construction material is removed from the loading rack. Therefore, the workability and safety when transporting the construction material can be improved.

[0008] In this case, the biasing member protrudes toward the building component further than the cushioning material and biases the building component toward the building component, and the biasing member biases the building component while the building component is supported by the support member and positioned by the positioning portion, thereby suppressing close contact between the cushioning material and the building component. With the above-described configuration, the biasing member biases the construction component, so that adhesion between the cushioning material and the construction component can be suppressed with a simple configuration.

[0009] In this case, the support member is a mounting member for placing the building component on, the mounting portion is removably attached to the upper surface of the mounting member and supports the building component from below, the positioning portion has an engaging portion that engages with an engaged portion formed on the building component, and the biasing member is an elastic spring, and when the building component is placed on the mounting member and the engaged portion is engaged with the engaging portion, it biases the building component upwardly, thereby suppressing close contact between the cushioning material and the building component. With the above-mentioned configuration, when the construction material is placed on the mounting member, even if the construction material is pressed against the buffer material by its own weight, the elastic spring prevents the buffer material and the construction material from coming into close contact with each other. Therefore, when the construction material is removed from the loading rack, the positioning member can be prevented from coming off the mounting member with a simple configuration.

[0010] In this case, a horizontally extending groove may be formed on the contact surface of the cushioning material with which the building component comes into contact, and the groove may extend horizontally from the outer edge of the contact surface. With the above-mentioned configuration, the grooves formed on the contact surface reduce the contact area between the cushioning material and the building component, further suppressing adhesion between the cushioning material and the building component. Also, the air between the cushioning material and the building component escapes to the outside of the positioning member, further suppressing adhesion between the cushioning material and the building component.

[0011] In this case, a through hole penetrating in the vertical direction is formed in the cushioning material, and a communication hole extending in the horizontal direction and communicating with the through hole is preferably formed in the side surface of the cushioning material. With the above-described configuration, the communication holes that communicate with the through holes allow air between the cushioning material and the construction component to escape to the outside of the positioning member, thereby further preventing the cushioning material and the construction component from coming into close contact with each other.

[0012] In this case, the engaging portion of the positioning part is an engaging convex part that protrudes from the mounting part toward the building component and engages with an engaged recess formed in the building component, the cushioning material has a through hole that penetrates in the vertical direction and through which the engaging convex part is inserted, and the elastic spring is a coil spring into which the engaging convex part is inserted and is positioned inside the through hole. With the above-mentioned configuration, the elastic spring is attached to the engaging protrusion and biases the construction material upward in the vicinity of the engaging protrusion, so that the contact between the cushioning material and the construction material can be suppressed with a simple configuration.

[0013] In this case, the placement member is a long rod-shaped member extending in the horizontal direction, and the mounting portion has an attachment piece arranged on the upper surface of the placement member, and first and second clamping pieces extending downward from both ends of the attachment piece in the width direction and clamping the placement member from the sides, the first clamping piece extending linearly downward from the attachment piece and holding the placement member from the side, and the second clamping piece extending parallel to the first clamping piece and having a holding portion holding the placement member from the side, and an inclined portion extending downward from the holding portion so as to move away from the placement member. With the above-mentioned configuration, the positioning member is firmly and detachably held by the holding portions of the first and second clamping pieces on the mounting member. This makes it possible to further prevent the positioning member from coming off the support member. In addition, the inclined portion of the second clamping piece makes it easy to attach the positioning member to the mounting member.

[0014] In this case, the mounting portion has an mounting piece that is arranged on the upper surface of the mounting member, and a protrusion that protrudes downward from the mounting piece and engages with a hole formed in the mounting member, the positioning member has a second biasing member that is provided on the protrusion and biases the mounting portion toward the mounting member, an upper end of the second biasing member is attached to the protrusion and a lower end of the second biasing member is attached to the mounting member, and the second biasing member biases the mounting portion and the cushioning material downward when the building component is placed on the mounting member and the engaged portion is engaged with the engaging portion, thereby suppressing close contact between the cushioning material and the building component. With the above-mentioned configuration, the biasing member suppresses the adhesion between the cushioning material and the construction member, and the second biasing member strengthens the force with which the positioning member is attached to the mounting member. Therefore, with a simple configuration, it is possible to further suppress the positioning member from coming off the support member when the construction member is removed from the loading rack.

[Figure 8] FIG. 13 is a front view of a positioning member according to a third embodiment. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0017] Hereinafter, an embodiment of the present invention will be described with reference to FIGS. This embodiment relates to a loading rack that can be transported while loaded with building materials, and that can improve workability and safety when transporting building materials. In the following description, as shown in Figure 1, the "up-down direction" refers to the up-down direction when the building materials are placed on the loading rack. Additionally, 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. Additionally, 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. Additionally, the "left-right direction" is a direction perpendicular to the "up-down direction" and the "front-rear direction".

[0018] <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.

[0019] 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.

[0020] As shown in FIG. 2, the construction component P placed on the loading rack 1 is composed of a surface material P1 that is exposed to the outside when attached to a building, and a frame P2 fixed to the back surface of the surface material P1. The frame P2 has a plurality of holes P2a formed therethrough in the thickness direction. The holes P2a correspond to engaged portions (engaged recesses) according to the present invention, and are engaged with engaging portions (engaging protrusions) of the positioning member 6, which will be described later.

[0021] 1, the loading rack 1 can load a plurality of building components P at intervals in the vertical direction. Specifically, the loading rack 1 can load six building components P at intervals in the vertical direction. Note that the number of building components P loaded on the loading rack 1 can be changed as appropriate.

[0022] As shown in FIG. 1, the loading rack 1 mainly comprises a pair of base members 2 that form the foundation of the loading rack 1, a plurality of pillar members 3 extending in the vertical direction, a mounting member 4 that is spanned across the plurality of pillar members 3 and on which a building member P is placed, a plurality of connecting members 5 that extend in the longitudinal direction of the loading rack 1 and connect the pillar members 3, and a positioning member 6 that determines the horizontal position of the building member P.

[0023] 1, the base member 2 is a member that serves as the foundation of the loading rack 1, and is installed on an installation surface such as a floor. A pair of base members 2 are provided at a predetermined interval in the width direction (i.e., the front-rear direction) of the loading rack 1, and extend in the length direction (i.e., the left-right direction) of the loading rack 1.

[0024] As shown in FIG. 1, the pillar members 3 extend in the vertical direction and serve as supports for the loading rack 1 as a whole. As shown in FIG. 3, the pillar member 3 has a hollow main body portion 3a that is elongated in the vertical direction, a connecting protrusion portion 3b formed at the upper end portion of the main body portion 3a, and a connecting recess portion 3c formed at the lower end portion of the main body portion 3a.

[0025] The main body portion 3a is a main body portion of the column member 3 arranged on the base member 2, and a plurality of the main body portions 3a are connected in the vertical direction to form the support columns of the loading rack 1. The main body portion 3a has a substantially rectangular cross section when viewed from above. A fixing portion 3d for fixing the connecting member 5 is formed on the outer surface of the main body portion 3a in the front-rear direction.

[0026] The connecting protrusion 3b is a fitting portion that detachably fits with the connecting recess 3c, and has a substantially U-shaped cross section in top view. The connecting protrusion 3b protrudes upward from the upper end of the main body 3a. The connecting protrusion 3b is disposed inside the main body 3a in top view. The connecting recess 3c is a fitted portion that detachably engages with the connecting protrusion 3b, and is the lower end portion of the main body 3a. The connecting protrusion 3b and the connecting recess 3c are detachably engaged with each other, thereby making it possible to adjust the height of the loading rack 1. In this embodiment, the connecting recess 3c is a lower end portion of the hollow cylindrical main body 3a, but if the main body 3a is a solid columnar member, it may be a hole formed in the lower end surface of the main body 3a.

[0027] 1, the mounting member 4 is a support member for supporting a building member P, and extends horizontally and is bridged across a plurality of pillar members 3. Specifically, the mounting member 4 extends in the width direction of the loading rack 1 and is disposed between a pair of pillar members 3 spaced a predetermined distance apart in the front-rear direction. The mounting member 4 is a long rod-shaped member extending horizontally, and is made of, for example, a long body processed from a square pipe. The upper surface of the mounting member 4 becomes a mounting surface 4a (support surface) on which the building component P is placed. The main body parts 3a of the pillar members 3 are attached to both ends of the mounting member 4 in the front-rear direction. The mounting member 4 supports the building component P from below via the positioning members 6.

[0028] 1, the connection members 5 are linking members that connect a pair of column members 3 arranged in the left-right direction. The connection members 5 maintain a predetermined distance between the pair of column members 3 and provide rigidity to the loading rack 1. The connection member 5 has an extending portion 5a extending in the length direction (left-right direction) of the loading rack 1, and fixed portions 5b provided at both ends of the extending portion 5a and fixed to the pillar members 3.

[0029] The extension portion 5a is a rod-shaped member that is long in the left-right direction and is made of a long body, for example, a processed square pipe. The extension portion 5a is disposed between the main body portions 3a of the pair of pillar members 3. The fixed portions 5b are attached to both ends of the extension portion 5a in the left-right direction. The fixed portion 5b is, for example, a metal plate-like member, and is attached to the outer surface of the extending portion 5a in the front-rear direction. The fixed portion 5b has a plurality of fixing holes 5c formed at predetermined intervals in the left-right direction. The fixing holes 5c and the fixing portion 3d of the pillar member 3 are mated and fastened with a bolt, so that the connection member 5 is fixed to the outer surface of the pillar member 3.

[0030] <Positioning member> As shown in Figs. 1 and 3, the positioning member 6 is a metal fitting for determining the horizontal position of the building member P placed on the mounting member 4, and is detachably attached to the mounting surface 4a of the mounting member 4. The positioning member 6 has an attachment portion 10 that is attached to the mounting member 4, a positioning portion 20 that positions the building member P, a cushioning material 30 that is arranged between the attachment portion 10 and the building member P, and a biasing member 40 that biases the building member P.

[0031] 3 to 6, the mounting portion 10 is a metal member having an inverted U-shaped cross section, and is detachably attached to the mounting member 4. A plurality of mounting portions 10 are attached to the mounting surface 4a of the mounting member 4, and support the building member P from below. The mounting portion 10 has an mounting piece 11 arranged on the mounting surface 4a of the mounting member 4, a first clamping piece 12 and a second clamping piece 13 extending downward from both ends in the width direction of the mounting piece 11 and clamping the mounting member 4 from the sides, and a protrusion 14 protruding downward from the mounting piece 11.

[0032] The mounting piece 11 is a substantially square plate-like portion, and is disposed on the mounting surface 4a of the mounting member 4. A positioning portion 20 is attached to the upper surface of the mounting piece 11. A protrusion portion 14 is attached to the lower surface of the mounting piece 11.

[0033] The first clamping piece 12 is a plate-like portion that extends linearly downward from the attachment piece 11 along the side surface 4b of the mounting member 4, and holds the mounting member 4 from the side. The second clamping piece 13 is a plate-like portion extending from the mounting piece 11 along the side surface 4b of the mounting member 4, and holds the mounting member 4 from the side. The second clamping piece 13 extends parallel to the first clamping piece 12, hanging down from the mounting piece 11, and has a holding portion 13a that holds the mounting member 4 from the side, and an inclined portion 13b that extends downward from the holding portion 13a so as to be away from the mounting member 4.

[0034] The holding portions 13a of the first clamping piece 12 and the second clamping piece 13 have elasticity, and are attached to the mounting member 4 in such a way that they sandwich both side surfaces of the mounting member 4 with the elasticity. The inclined portion 13b of the second clamping piece 13 is formed so as to be inclined and spread outward, so that the mounting part 10 can be easily mounted to the mounting member 4. In this manner, of the first clamping piece 12 and the second clamping piece 13 which clamp the mounting member 4 from the sides, one is formed so as to extend linearly downward and the other is formed so as to be inclined and spread outward, so that the mounting part 10 can be easily mounted while maintaining the clamping force.

[0035] 3, the protrusion 14 is a portion that protrudes downward from the center of the mounting piece 11, and engages with a hole 4c formed in the upper surface of the mounting member 4. The mounting part 10 can maintain its horizontal position relative to the mounting member 4 by the protrusion 14. In addition, when the clamping force of the first clamping piece 12 and the second clamping piece 13 is sufficiently high, the mounting part 10 may be configured not to have the protrusion 14. According to this configuration, the mounting part 10 can be attached regardless of the position of the hole 4c formed in the mounting member 4, so that it is possible to support building members P of various shapes.

[0036] 3 to 6, the positioning portion 20 is provided on the mounting portion 10 and serves to position the building component P. Specifically, the positioning portion 20 is an engagement portion (engagement protrusion) that protrudes upward from the center portion of the mounting piece 11 of the mounting portion 10 toward the building component P and engages with a hole P2a formed in the building component P. By engaging the positioning portion 20 with the hole P2a formed in the building component P, the building component P placed on the loading rack 1 can be prevented from shifting in position in the horizontal direction.

[0037] As shown in Figs. 3 to 6, the cushioning material 30 is disposed between the mounting portion 10 and the construction component P, has elasticity, and is a member for preventing damage to the construction component P. The cushioning material 30 can absorb the shaking of the construction component P when the loading rack 1 is transported. The cushioning material 30 is a substantially square rubber plate member made of synthetic resin having a predetermined rigidity, such as polystyrene. The cushioning material 30 is provided on the mounting piece 11 of the mounting part 10, and is formed to be substantially the same size as the mounting piece 11. The cushioning material 30 is formed with a through hole 31 that penetrates in the vertical direction and through which the positioning part 20 is inserted. The cushioning material 30 is attached to the mounting part 10 with the positioning part 20 inserted through the through hole 31.

[0038] 4 to 6, a plurality of horizontally extending grooves 32 are formed on the contact surface 30a where the cushioning material 30 contacts the building component P. Specifically, the plurality of grooves 32 having a U-shaped cross section extend horizontally from the outer edge of the contact surface 30a and are formed in a lattice pattern on the contact surface 30a. By forming a plurality of grooves 32 on the contact surface 30a, the contact area with the building component P is reduced, and therefore adhesion between the cushioning material 30 and the building component P is suppressed. In addition, by extending horizontally from the outer edge of the contact surface 30a, air between the cushioning material 30 and the building component P escapes to the outside of the positioning member 6. Therefore, adhesion between the cushioning material 30 and the building component P is suppressed.

[0039] The shape, position, and number of the grooves 32 are not limited to those described above, and may be any shape that suppresses adhesion between the cushioning material 30 and the building component P. For example, the grooves 32 may have a V-shaped cross section. The grooves 32 may extend only in the left-right direction or the front-back direction, or may extend in a curved shape. Furthermore, the grooves 32 are not limited to being slit-shaped, and may have a circular shape when viewed from above.

[0040] 4 to 6, a communication hole 33 is formed on the outer surface 30b of the cushioning material 30, extending in the horizontal direction and communicating with the through hole 31. Specifically, the communication hole 33 is formed in the center of each outer surface 30b of the cushioning material 30. By forming a communication hole 33 that communicates with the through hole 31, the air that has accumulated inside the through hole 31 is allowed to escape to the outside of the positioning member 6, thereby preventing the cushioning material 30 and the building member P from coming into close contact with each other.

[0041] 4 to 6, the bottom surface 30c of the cushioning material 30 has cutouts 34 that extend horizontally and communicate with the through-holes 31. Specifically, a plurality of cutouts 34 having an inverted U-shaped cross section extend horizontally from the outer edge of the bottom surface 30c and are formed in a cross shape on the bottom surface 30c. By forming the cutout portion 34 communicating with the through hole 31, the air accumulated inside the through hole 31 is allowed to escape to the outside of the positioning member 6, thereby preventing the cushioning material 30 and the building member P from coming into close contact with each other. Double-sided tape is provided on the bottom surface 30c of the cushioning material 30. The cushioning material 30 is attached to the upper surface of the attachment piece 11 by the double-sided tape.

[0042] As shown in Figs. 4 to 6, the urging member 40 is an elastic spring provided on the mounting portion 10. The urging member 40 is attached to the upper surface of the mounting piece 11 of the mounting portion 10, protrudes toward the building component P beyond the cushioning material 30, and urges the building component P toward the building component P. Specifically, the urging member 40 is a coil spring, and the positioning portion 20 is inserted into the coil spring. The urging member 40 is disposed inside the through hole 31 and attached to the mounting portion 10. The biasing member 40 biases the building member P upward when the building member P is placed on the mounting member 4 and the hole P2a of the building member P is engaged with the positioning portion 20, thereby suppressing adhesion between the cushioning material 30 and the building member P.

[0043] The biasing member 40 biases the building member P in a state in which the building member P is placed on the placing member 4 and positioned by the positioning part 20. Therefore, even if the building member P is pressed against the buffer material 30 by its own weight when the building member P is placed on the placing member 4, the biasing force of the biasing member 40 suppresses the close contact between the buffer material 30 and the building member P. Therefore, it is possible to prevent the positioning member 6 from coming off the mounting member 4 when the building member P is lowered from the loading rack 1. Also, since the biasing member 40 is a coil spring, it is possible to prevent the cushioning material 30 and the building member P from coming into close contact with each other with a simple configuration. Furthermore, by forming a plurality of grooves 32 on the contact surface 30a of the cushioning material 30, the cushioning material 30 and the building member P are prevented from coming into close contact with each other.

[0044] With the above configuration, even if the loading rack 1 is vibrated when transported by a vehicle such as a truck or ship, and the building member P is pressed against the buffer material 30, the biasing force of the biasing member 40 suppresses the close contact between the buffer material 30 and the building member P. Therefore, when the building member P is removed from the loading rack 1, it is possible to suppress the positioning member 6 from coming off the placement member 4.

[0045] <Second embodiment> Next, a positioning member 6A according to a second embodiment will be described with reference to Fig. 7. Note that a description of the same contents as those of the positioning member 6 described above will be omitted. The positioning member 6A has an attachment portion 10 attached to the mounting member 4, a positioning portion 20 that positions the building member P, a buffer material 30 disposed between the attachment portion 10 and the building member P, a biasing member 40 that biases the building member P, and a second biasing member 50 that biases the attachment portion 10. The positioning member 6A is different from the positioning member 6 described above in the configuration of the second biasing member 50.

[0046] 7, the second biasing member 50 has an inner spring 51 provided on the mounting portion 10, and an anchor portion 52 provided on a lower end portion of the inner spring 51. An upper end portion of the second biasing member 50 is attached to the protrusion portion 14 of the mounting portion 10, and is disposed inside the mounting member 4. A lower end portion of the second biasing member 50 is attached to the lower surface of the mounting member 4.

[0047] The inner spring 51 is a coil spring, and is provided on the protrusion 14 of the mounting part 10. An upper end 51a of the inner spring 51 is hooked into a spring engagement hole 14a formed in the lower end of the protrusion 14 of the mounting part 10, and is disposed inside the mounting member 4. A lower end 52b of the inner spring 51 is inserted into a lower surface hole 4d formed in the lower surface of the mounting member 4, and is attached to the anchor part 52. The anchor portion 52 is a long rod-shaped member, and is provided at the spring lower end portion 52b of the inner spring 51. The anchor portion 52 is disposed on the lower surface side of the mounting member 4, and the inner spring 51 inserted into the lower surface hole portion 4d is attached to the anchor portion 52.

[0048] The second biasing member 50 biases the attachment portion 10 and the cushioning material 30 downward toward the mounting member 4. Specifically, the inner spring 51 is hooked onto the protruding portion 14, protrudes from inside the mounting member 4 through the lower surface hole portion 4d to the lower surface side of the mounting member 4, and is attached to the anchor portion 52. Then, the anchor portion 52 is engaged with the mounting member 4, so that the attachment portion 10 is biased downward toward the mounting member 4 by the inner spring 51.

[0049] With the above-mentioned configuration, when the building member P is placed on the mounting member 4 and the hole P2a of the building member P is engaged with the positioning portion 20, the second biasing member 50 biases the mounting portion 10 downward, thereby suppressing close contact between the cushioning material 30 and the building member P. When the building component P is placed on the mounting member 4, even if the building component P is pressed against the buffer material 30 by its own weight, the mounting portion 10 is drawn toward the mounting member 4 by the biasing force of the second biasing member 50. Therefore, the adhesion between the buffer material 30 and the building component P is suppressed.

[0050] In this way, the force with which the positioning member 6A is attached to the mounting member 4 by the second biasing member 50 is increased. Therefore, it is possible to prevent the positioning member 6 from coming off the mounting member 4 when the building member P is lowered from the loading rack 1. In addition, since the second biasing member 50 is a coil spring, it is possible to prevent the cushioning material 30 and the building member P from coming into close contact with each other with a simple configuration.

[0051] <Third Example> Next, a positioning member 6B according to a third embodiment will be described with reference to Fig. 8. Note that a description of the same contents as those of the positioning members 6 and 6A described above will be omitted. The positioning member 6B has an attachment portion 10 attached to the mounting member 4, a positioning portion 20 that positions the building member P, a second buffer material 60 disposed between the attachment portion 10 and the building member P, and a third biasing member 70 that biases the building member P. The positioning member 6B is different from the positioning members 6 and 6A described above in the configurations of the second buffer material 60 and the third biasing member 70. The positioning member 6B may further have a second biasing member 50.

[0052] 8, the second cushioning material 60 is disposed between the mounting portion 10 and the construction component P, has elasticity, and is a member for preventing damage to the construction component P. The second cushioning material 60 can absorb the shaking of the construction component P when the loading rack 1 is transported. The second cushioning material 60 has a spring portion 61 provided on the mounting portion 10, and a support portion 62 that abuts against the architectural component P and supports the architectural component P from below.

[0053] The spring portion 61 is a coil spring with a relatively large hole diameter, and is provided on the upper surface of the mounting piece 11 of the mounting portion 10. The spring portion 61 is attached to the upper surface of the mounting piece 11 with double-sided tape. The support portion 62 is a rubber plate member formed to have approximately the same size as the mounting piece 11, and is provided on the upper end portion of the spring portion 61. The support portion 62 is formed with an insertion hole 62a that penetrates in the vertical direction and through which the positioning portion 20 is inserted. The second cushioning material 60 is attached to the attachment portion 10 in a state in which the positioning portion 20 is inserted into the inside of the spring portion 61 and into the insertion hole 62a.

[0054] The third biasing member 70 is an elastic spring provided on the mounting portion 10. The third biasing member 70 is attached to an upper surface of the mounting piece 11 of the mounting portion 10, and biases the second cushioning material 60 downward toward the mounting portion 10. Specifically, the third biasing member 70 is a coil spring, and the positioning portion 20 is inserted into the coil spring. The third biasing member 70 is disposed inside the insertion hole 62a of the spring portion 61, and attached to the mounting portion 10. An upper end portion of the third biasing member 70 is attached to a lower surface of the support portion 62 of the second cushioning material 60. The third biasing member 70 biases the support portion 62 of the second cushioning material 60 downward when the building member P is placed on the mounting member 4 and the hole P2a of the building member P is engaged with the positioning portion 20, thereby suppressing adhesion between the second cushioning material 60 and the building member P.

[0055] With the above-described configuration, the third biasing member 70 biases the second cushioning material 60 in a state in which the building member P is placed on the mounting member 4 and positioned by the positioning portion 20. Therefore, even if the building member P is pressed against the second cushioning material 60 by its own weight when the building member P is placed on the mounting member 4, the biasing force of the third biasing member 70 suppresses the adhesion between the cushioning material 30 and the building member P. Therefore, when the building member P is lowered from the loading rack 1, the positioning member 6B can be prevented from coming off the mounting member 4.

[0056] <Other embodiments> The loading rack 1 of the present invention is not limited to the above embodiment. In this embodiment, the case where an exterior wall panel is placed as a building component P is described as an example. However, the present invention is not limited to this, and is also suitable for placing panel components other than exterior wall panels, or pallets, containers, plate-shaped components, rod-shaped components, box-shaped components, cylindrical components, etc.

[0057] In the present embodiment, the case where the loading rack 1 vibrates and the construction material P is pressed against the buffer material 30 by its own weight has been described as an example. However, the present invention is not limited to this, and may be used to suppress the construction material P from being pressed against the buffer material 30 and coming into close contact with it due to the vibration of the loading rack 1 in the horizontal direction. For example, the positioning member 6 may be disposed on a side of the connection member 5 (corresponding to a support member) facing the side of the building member P. In addition, an outer frame (corresponding to a support member) that surrounds the building member P is provided separately on the loading rack 1, and the positioning member 6 may be disposed on a side of the outer frame facing the side of the building member P.

[0058] In this way, even if the outer surface of the building component P is pressed against the buffer material 30 by vibration in the horizontal direction, the biasing force of the biasing member 40 suppresses the adhesion between the buffer material 30 and the building component P. Therefore, it is possible to suppress the positioning member 6 from coming off the connecting member 5 or the outer frame.

[0059] 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]
