Description

  The present invention relates to a support base used for supporting a roll body formed by winding a polyvinyl alcohol film, which is a forming material such as a polarizing film, around a core material at both right and left ends of the core material.

  A polarizing film is used for the liquid crystal display, and the polarizing film is obtained by dyeing and uniaxially stretching a polyvinyl alcohol film. And the polyvinyl alcohol-type film is generally manufactured as follows. That is, after dissolving a polyvinyl alcohol-type resin in a solvent and defoaming to prepare a stock solution, an aqueous polyvinyl alcohol-type resin solution is extruded from the T-type slit die onto the outer peripheral surface of the drum-type roll. And it is manufactured by casting, film-forming, and drying on the drum-type roll outer peripheral surface. Then, it peels from the said drum type | mold roll, passes through processes, such as heat processing, and is wound up by the core material, The roll body of a polyvinyl alcohol-type film is formed.

  And when manufacturing the said polarizing film, a polyvinyl-alcohol-type film is drawn out from the said roll body, and dyeing | staining and uniaxial stretching are performed. Since the polarizing film manufactured in this way is used for a liquid crystal display, a film excellent in uniformity in optical performance such as light transmittance is required.

  In order to meet the demand, it is required that the polyvinyl alcohol film of the roll body is not damaged or deformed when the roll body is stored or transported. That is, when scratches, deformations, etc. occur, the light transmission becomes uneven and the optical performance is inferior.

Therefore, conventionally, a method of storing or transporting a roll body for preventing the above-described scratches and deformations has been proposed (for example, see Patent Document 1). This method is a method in which the left and right ends of the core material of the roll body are supported by a gantry. That is, the frame is provided with horizontal frame portions at both left and right end portions, and the support is performed by placing the left and right end portions of the core material of the roll body on the both frame portions. ing.
JP 2001-315886 A (paragraph [0016], FIG. 2)

  However, since the gantry in Patent Document 1 merely supports the roll body, the space in the storage place or the like is effective when the roll body is supported for storage or transportation (usage of the gantry). The use is not considered. That is, for example, the pedestal in Patent Document 1 is not considered to be stacked in two or more stages, and therefore must be stored in one stage at a storage place or the like, and stored more than in the case of stacking two or more stages. The number of roll bodies that can be equalized is reduced. Also, since the storage method of the frame itself when not using the frame is not taken into consideration, similarly, the space availability in the storage state (the frame is not used) is poor, and the number of frames that can be stored is reduced. .

  The present invention has been made in view of such circumstances, and an object of the present invention is to provide a support base that can effectively use a space in a storage place or the like in a use state or a non-use state.

  In order to achieve the above object, the support base of the present invention supports a roll body formed by winding a polyvinyl alcohol-based film around a core material at both right and left ends of the core material, in the supported state, or In a folded state, a plurality of support bases can be stacked, and four struts standing at the four corners of the virtual rectangle are connected to each other so as to constitute the four sides of the virtual rectangle. And a pair of left and right support frames configured to connect and support the left and right ends of the core member by connecting the support columns so as to form the short sides of the virtual rectangle above the connection frames. The height of each support column is set to be larger than the diameter of the roll body, and one set of two support columns including the support frame has an upper part from the intermediate rotation part. Standing up and inward It is configured freely, and the formation position of the rotation part is positioned at a height position between the connection frame and the support frame, and when the upper part stands up, the top part is stacked on the other part. Other support bases that are formed on a support part that fits and supports the lower end part of the column of the support base, and whose rotating part is stacked on this when the upper part is folded by inward lying down It takes the structure that it is formed in the support part which fits and supports the lower end part of this pillar.

  That is, in a state where the roll body is supported by the support base of the present invention (use state), the upper part of the support column is in an upright state, and the left and right ends of the core of the roll body are supported and fixed by the support frame. ing. The support base of the present invention is formed in a support portion that is supported by being fitted to the lower end portion of the post of another support base that is stacked on the top of the support column in an upright state. And since the height dimension of the said support | pillar is set larger than the diameter of a roll body, the support stand of the state which supported the roll body can be stacked | stacked two or more steps, In that state, upper and lower roll bodies are mutually Can be prevented from contacting. On the other hand, in a state where the support base of the present invention is not used for supporting the roll body (non-use state), the upper part of the support is in an inwardly lying state (folded state), and the height of the support base is lowered. be able to. The support base of the present invention is a support that the rotating part fits and supports the lower end part of the pillar of another support base that is stacked on the upper part when the upper part is inwardly lying down. Since it is formed in the receiving portion, it is possible to stack two or more support bases in which the upper part of the support column is in an inwardly lying state (folded state).

  As described above, the support base of the present invention can be stacked in two stages or more with the upper part of the support column in an upright state in the use state, and the upper part of the support column in an inwardly lying state (folded) in the non-use state. State) can be stacked in two or more stages. For this reason, the support base of the present invention can effectively use a space such as a storage place even when storing or transporting while supporting the roll body, or when storing the support base itself. Thus, many roll bodies and the support table itself can be stored or transported.

  In particular, when the support frame is formed with a U-shaped portion that allows the left and right ends of the core material to be fitted from above, and an opening / closing member that allows the upper opening of the U-shaped portion to be opened and closed is provided. Thus, the support and fixing of the core material becomes more stable, and the roll body of the polyvinyl alcohol film can be reliably protected. In particular, the opening / closing member can prevent the roll body from dropping due to vertical shaking during transportation.

  Further, in the case where the support frame is provided with stoppers that come into contact with both left and right end surfaces of the core member, the roll body is displaced in the axial direction when the roll body is stored or transported, and the U-shaped. It is prevented from falling off the part.

  Further, when a reinforcing frame is provided between the connecting frames facing each other and a mounting member for mounting the core material is provided on the reinforcing frame, the support base itself is stored. Further, by placing the core material on the mounting member, it can be stored together with the support base.

  In addition, even when a mounting portion for mounting the core material is formed in the connecting frame constituting the short side of the virtual rectangle and in the reinforcing frame between them, when storing the support itself, etc. In addition, by placing the core material on the placement portion, it can be stored together with the support base.

  And when the upper part of the adjacent support | pillar in the long side of the said virtual rectangle is connected so that attachment or detachment is possible with a connecting rod, by connecting with the connecting rod, The portion can be held in an upright position without falling inward or outward. And when making the said upper part fall inward, the connection by the said connection rod can be removed.

  Furthermore, the height of the column in the state where the length of the long side of the virtual rectangle is 2 to 5 m, the length of the short side is 0.5 to 1.5 m, and the upper part of the column is raised. In the range of 0.5 to 1.5 m, when the height of the column in the state where the upper part of the column is lying down is set to 2/3 or less of the column height in the standing state, It is effective for storing or transporting a roll of scale.

  In addition, in the lower part from the rotating part of the support column, when the part on the opposite side to the fall direction of the upper part is formed higher than the part in the fall direction, the outward part of the upper part of the support column Lodging can be reliably prevented.

  And in the long side of the above-mentioned virtual rectangle, when the connecting frame and the upper part of the support are detachably supported by the support rod, the support rod is supported by the support rod. The upper portion can be held upright so as not to fall inward or outward. And when the above-mentioned upper part falls down inward, the support by the above-mentioned support bar can be removed.

  Next, embodiments of the present invention will be described in detail with reference to the drawings. However, the present invention is not limited to this.

  FIG. 1 shows a first embodiment of a support base according to the present invention. This support base supports a roll body R (see FIGS. 2A and 2B) obtained by winding a polyvinyl alcohol film around a core material A at both right and left ends of the core material A. . For this purpose, this support base is provided so that four columns stand upright at the four corners of the virtual rectangle, and these four columns 1 constitute the four sides of the virtual rectangle at the lower part thereof. It connects with the connection frame 2 so that it may do. Further, the struts 1 adjacent to each other on the short side of the virtual rectangle are connected by a support frame 3 at a position above the connection frame 2, and the roll is attached to the U-shaped portion 3 a at the center of the support frame 3. By fitting (supporting and fixing) both left and right ends of the core material A of the body R, the roll body R can be supported (see FIGS. 2A and 2B). And in this invention, the rotation part 10 is provided in the height position between the connection frame 2 and the support frame 3, respectively in the support | pillar 1 adjacent in the short side of the said virtual rectangle, The rotation An upper portion 1a from the portion 10 is formed to be able to stand up and inwardly fall. In the inward lying down, the rotating part 10 becomes the top part. Furthermore, the lower end portion 1c of each support column 1 located at the four corners of the virtual rectangle is also the top portion of the upper portion 1a of the upright support column 1 and the rotation unit 10 which is the top portion in the inwardly lying state. In addition, it is formed in a dome shape having a rectangular shape in plan view with an opening at the bottom so as to be externally fitted. Here, the top part of the upper part 1a and the turning part 10 in the inwardly lying state are fitted and supported by the lower end part 1c of the support column 1 of another supporting base stacked thereon. It becomes. Further, the width of the support base (the length of the virtual rectangle in the short side direction) and the height of each support column 1 are set larger than the diameter of the roll body R.

  Then, as shown in FIGS. 2A and 2B, when storing or transporting the roll body R while being supported by the support base, the upper portion 1a of the support column 1 is raised, The left and right ends of the core material A of the roll body R are fitted into the U-shaped portion 3 a of the support frame 3. Moreover, the said support stand supports the roll body R by making each lower end part 1c of the support | pillar 1 of another support stand fit into the top part of each support | pillar 1 in which the upper part 1a of the support | pillar 1 is standing. In this state, two or more stages can be stacked. In this state, since the height dimension of each support column 1 is set to be larger than the diameter of the roll body R, the upper and lower roll bodies R are not in contact with each other. In addition, since the width of the support base is also set larger than the diameter of the roll body R, when the support bases are arranged in the short side direction of the virtual rectangle, the columns 1 of the adjacent support bases or the virtual rectangles Even if it arranges so that the connection frames 2 which comprise a long side may contact | abut, the adjacent roll bodies R do not contact.

  On the other hand, as shown in FIGS. 3A and 3B, when the support base itself is stored or transported (the support base is not used), the upper portion 1a of the support column 1 is set to the long side of the virtual rectangle. The height of the support base is lowered by lying inward and folding. Moreover, since the said rotation part 10 turns into a top part by this folding, the said support stand is folded by making the top part fit the lower end part 1c of the support | pillar 1 of the other support stand stacked on it. Two or more levels can be stacked in a state.

  As described above, the support base of the present invention has two or more stages whether it is stored or transported in a use state in which the roll body R is supported, or when the support base itself is folded and stored in a non-use state. Since they can be stacked, a space such as a storage place can be used effectively, and a large number of roll bodies R and the support itself can be stored or transported in a small space.

  The support base of the present invention will be described in more detail. The support column 1, the connection frame 2, and the support frame 3 are formed of iron hollow square material, and the connection between the support column 1 and the connection frame 2 and the support column 1 and the support frame. The connection with 3 is performed by welding. Moreover, as needed, from the viewpoint of rust-proofing the support table, the entire surface of the support table may be hot-dip galvanized.

  As shown in FIG. 4 with respect to the pivoting portion 10 of the main part, the column 1 has a bottom portion of the upper portion 1a from the pivoting portion 10 and a lower portion 1b from the pivoting portion 10. Inserted into the top. In the rotating portion 10, the upper portion 1a is provided with protruding rod protrusions 11 extending on both side surfaces facing the short side of the virtual rectangle. The lower portion 1b is loosely fitted into a substantially U-shaped cutout portion 14 provided on the upper end surface. Further, substantially L-shaped long holes 15 (see FIG. 5) are formed on both side surfaces below the protrusion 11 (the portion inserted into the lower portion 1b). Then, the bolt portion (male screw portion) of the hexagon head bolt 16 is inserted into the substantially L-shaped elongated hole 15 on one side surface, and the substantially L-shaped elongated hole (not visible in FIG. 4) on the other side surface side. A loosely fitting nut 17 (see FIG. 1) is screwed into the inserted portion so as to be freely fitted. The hexagon head bolt 16 is inserted into a through hole provided on one side surface and the other side surface of the lower portion 1b.

  The lower portion 1b of the support column 1 has a notch 13 formed on its inward side surface (the side facing the inner side in the long side direction of the virtual rectangle). The portion 1a of the above lies inward (in the direction of arrow D). The state shown in FIG. 4 is an upright state of the support column 1, and the protruding portion 11 of the upper portion 1 a is loosely fitted into the notch portion 14 on the upper end surface of the lower portion 1 b, thereby maintaining the stable standing state. Yes. Then, when lying down from the standing state, the upper portion 1a of the column 1 is lifted slightly upward to remove the protrusion 11 from the notch 14 of the lower portion 1b, and inwardly as shown in FIG. Lay down. In this embodiment, as shown in FIGS. 1 and 3A, the upper portion 1a is supported on the upper surface of the connecting frame 2 so that the upper portion 1a is horizontal in an inwardly lying state. A supporting rod 4 is erected.

  As shown in FIG. 1, the support frame 3 is formed in a substantially square shape, and the left and right ends of the core material A can be fitted into the center U-shaped portion 3 a from above. The width and depth of the U-shaped part 3a are slightly larger (about 10 mm or less) than the diameter of the core material A. The support frame 3 is provided with a rod-shaped opening / closing member 31 that allows the opening of the U-shaped portion 3a to be opened and closed. This rod-shaped opening / closing member is pivotable with one end portion serving as a fulcrum, and the other end portion is locked by a lock mechanism (not shown). When the left and right ends of the core material A are supported and fixed, the left and right ends of the core material A are fitted into the U-shaped portion 3a from above with the opening of the U-shaped portion 3a opened. Then, the opening / closing member 31 closes and locks the opening of the U-shaped portion 3a. When the left and right ends of the core material A are taken out from the U-shaped portion 3a, the opening / closing member 31 is unlocked to open the U-shaped portion 3a, and the left and right ends of the core material A are opened. Remove the part. Such a U-shaped portion 3a and the opening / closing member 31 make the support and fixing of the core material A more stable, and the polyvinyl alcohol film of the roll body R can be reliably protected. In particular, the opening / closing member 31 can prevent the roll body R from falling due to vertical shaking during transportation.

  The support frame 3 is provided with plate-like stoppers 32 with which the left and right end surfaces of the core A abut when the roll body R is supported, and covers the lower half of the U-shaped portion 3a. It is provided as follows. The stopper 32 prevents the roll body R from being displaced in the axial direction when the roll body R is stored or transported, and prevents contact between the end surface of the roll-shaped polyvinyl alcohol film and the support frame 3. Further, the roll body R is prevented from falling off from the U-shaped portion 3a. Further, the stopper 32 is rotatable about one of the left and right ends, and is locked by a lock mechanism (not shown) at the other end. As a result, the stopper 32 can be opened and the left and right ends of the core A can be held by a chuck or the like, and the left and right ends of the core A can be fitted into the U-shaped portion 3a and the U-shaped Removal from 3a can be facilitated. For this reason, the dent etc. of the polyvinyl-alcohol-type film by trunk | drum suspension (the method of supporting and suspending in the part of a polyvinyl-alcohol-type film) can be prevented.

  Further, below the support frame 3, an auxiliary frame 33 is provided to connect the upper portion 1 a of the support column 1 in the short side direction and assist the support frame 3. The support column 7 hangs down. In addition, a lower auxiliary column 8 is erected in the center of the connecting frame 2 constituting the short side of the virtual rectangle. In the state where the upper portion 1a of the support column 1 stands, the upper auxiliary support column 7 and the lower auxiliary support column 8 are positioned coaxially, and the lower end surface of the upper auxiliary support column 7 and the upper end surface of the lower auxiliary support column 8 are Are in contact. Thereby, it can prevent that the support frame 3 and the support | pillar 1 bend in the case of the pitching at the time of transport.

  Further, a single reinforcing frame 21 is provided between the connecting frames 2 constituting the long side of the virtual rectangle in parallel with them. The number of the reinforcing frames 21 is not particularly limited, but it is preferable that one or more reinforcing frames 21 are provided. A reinforcing frame 22 is also provided between the reinforcing frame 21 and the connecting frame 2 constituting the long side along the short side direction of the virtual rectangle. The number of the reinforcing frames 22 is not particularly limited, but is preferably two or more on one side by center distribution. When there are two or more, it becomes possible to carry the forklift claw from the short side of the virtual rectangle, so that it is easy to carry into the container or the like. Further, a mounting member 5 for mounting the core material A is provided on the upper surface of the reinforcing frame 22. As shown in FIG. 6, the mounting member 5 has a substantially U-shaped outer plate 5a whose bottom is horizontally formed, and is inclined so as to be in contact with the bottom and each side wall inside the outer plate 5a. The two inclined plates 5b fixed in a shape, and a rubber sheet 5c attached to the upper surface of both inclined plates 5b and the upper surface of the bottom portion between both inclined plates 5b. As shown in FIG. 1, the mounting member 5 is provided so that the side wall of the outer plate 5a faces the short side of the virtual rectangle, and as shown in FIGS. The core material A is placed along the long side direction of the virtual rectangle and is protected by the rubber sheet 5c (see FIG. 6). Further, by providing the above-described mounting member 5, the storage of the core material A can be performed together with the support base when storing the support base itself, and is separately provided for the storage of the core material A. There is no need to provide a storage space. When the polyvinyl alcohol film is wound around the core material A, the support base on which the core material A is placed is moved to the winding process, and the core material A is taken out of the support base and set on the winder. After the winding is completed, the roll R (see FIGS. 2 (a) and (b)) is taken out from the winder, and the supporting base is directly used as shown in FIGS. 2 (a) and 2 (b). The roll body R can be stored or transported by being supported and fixed to the support frame 3.

  Further, as shown in FIGS. 1 and 2 (a) and 2 (b), when the upper portion 1a of the support column 1 is held upright, the upper portion 1a of the adjacent support column 1 on the long side of the virtual rectangle. By linking the connecting rod 6 to the upper portion, the upper portion 1a of the support column 1 is prevented from falling inward or outward so that the standing state is stabilized, and the roll body R is more reliably prevented from falling off. The left and right ends of the connecting rod 6 are bent at a right angle downward, and the connecting rod 6 is detachable using a cylindrical body 61 into which the bent portion is inserted. As shown in FIGS. 3A and 3B, when the upper portion 1a is to be laid down, the connecting rod 6 is not necessary, and therefore a storage cylinder 62 is provided in the lower portion 1b. ing.

  The size of the support base of the present invention is not particularly limited, but from the viewpoint of being effective for storing or transporting a long roll body, the length of the long side of the virtual rectangle is in the range of 2 to 5 m, It is preferable to set the length of the short side in the range of 0.5 to 1.5 m and the height of the column 1 in the state where the upper portion 1a of the column 1 is upright in the range of 0.5 to 1.5 m. . More preferably, the height of the column 1 when the upper portion 1a of the column 1 is lying down is set to 2/3 or less of the height of the column 1 in the standing state.

  In addition, the dimensions of the roll body are not particularly limited, but from the viewpoint of storing or transporting a large amount of polyvinyl alcohol film, and from the viewpoint of corresponding to the widening of the polarizing film, the width of the polyvinyl alcohol film is 2 m. More preferably, it is 2.5 m or more, particularly 3 m or more. However, if it exceeds 5 m, the length becomes too long and the handleability deteriorates, so the upper limit is preferably 5 m. Further, the length of the polyvinyl alcohol film is also set to 3000 m or more, preferably 4000 m or more, particularly preferably 5000 m or more from the same viewpoint and from the viewpoint of corresponding to the lengthening of the polyvinyl alcohol film. However, if it exceeds 15000 m, the outer diameter becomes too large and the handleability deteriorates, so the upper limit is preferably 15000 m.

  FIG. 7 shows a modification of the column 1 in the support base of the present invention. In the lower part 1b from the rotating part of the support column 1, the part of the upper part 1a opposite to the falling direction is formed higher than the part in the falling direction. By forming in this way, it becomes possible to reliably prevent the upper portion 1a of the support column 1 from falling outward.

  8 (a) and 8 (b) show a second embodiment of the support base of the present invention. As shown in FIG. 8 (a), when the support 1 holds the upper portion 1a of the support column 1 in an upright state, the connection frame 2 having the long side of the virtual rectangle and the upper portion 1a of the support column 1 are The support rod 9 is used for the support. This stabilizes the standing state so that the upper portion 1a of the support column 1 does not fall inwardly or outwardly, and the roll body R is more reliably prevented from falling off. The support bar 9 is rotatably attached to the connecting frame 2 and is detachable from the upper portion 1 a of the support column 1. Then, as shown in FIG. 8B, when the upper portion 1 a is laid down, the support bar 9 is not necessary and is held by the holding portion 91 provided in the connection frame 2. When the support rod 9 is provided, the connecting rod 6 and the cylinders 61 and 62 (see FIG. 1) that span the portion 1 a above the adjacent strut 1 do not have to be provided. Except this, it is the same as the support stand of the said 1st Embodiment, and attaches | subjects the same code | symbol to the same part.

  FIG. 9 shows a support frame 3 in the third embodiment of the support base of the present invention. The support frame 3 in the support base is in contact with the left and right end surfaces of the core A when the roll body R (see FIGS. 2A and 2B) is supported by the central U-shaped portion 3b. A horseshoe-shaped stopper 34 is provided. The horseshoe-shaped stopper 34 has a plate-like shape formed along the curve of the bottom of the U-shaped part 3b, and the curved part inside the horseshoe-shaped protrudes from the bottom of the U-shaped part 3b. It is provided in the state. The protruding width is set to be equal to or less than the thickness of the peripheral wall of the core material A. Other than this, it is the same as the support base of the first embodiment, and the same reference numerals are given to the same parts [In FIG. 9, the opening of the U-shaped part 3b is made openable and closable. The opening / closing member 31 (see FIG. 1) is omitted).

  Also in the third embodiment, when the roll body R (see FIGS. 2A and 2B) is stored or transported by the horseshoe-shaped stopper 34, the axial deviation of the roll body R is prevented. Can be prevented. As a result, contact between the end surface of the roll-shaped polyvinyl alcohol film and the support frame 3 can be prevented, and the roll body R can be prevented from falling off from the U-shaped portion 3b. Furthermore, since the protrusion width of the horseshoe-shaped stopper 34 from the bottom of the U-shaped part 3b is set to be equal to or less than the thickness of the peripheral wall of the core A, the core is left as it is (without opening and closing the stopper 34). The left and right ends of the material A can be grasped by a chuck or the like. For this reason, workability is good.

  As a fourth embodiment of the support base of the present invention, in the support base of the third embodiment, a plate-like stopper (either left or right) similar to the first embodiment is provided outside the horseshoe-shaped stopper 34. When a stopper 32 (see FIG. 1) is provided which is rotatable about one end of the shaft and locked by a locking mechanism at the other end, a roll body R [FIGS. 2A and 2B] is provided. When storing or transporting the reference, it is possible to more reliably prevent the roll body R from shifting in the axial direction. As a result, contact between the end surface of the roll-shaped polyvinyl alcohol film and the support frame 3 can be more reliably prevented, and the roll body R can be more reliably prevented from falling off from the U-shaped portion 3b. Can do.

  In the third and fourth embodiments, the horseshoe-shaped stopper 34 is provided as the stopper 34 with which the left and right end faces of the core material A come into contact. However, the shape is not particularly limited, and is linear or A half moon or the like may be used. However, from the viewpoint of matching the shapes of the left and right end faces of the peripheral wall of the core material A, a horseshoe shape is preferable.

  Moreover, in the said 3rd and 4th embodiment, although the protrusion width | variety which protrudes from the bottom part of the said U-shaped part 3b of the stopper 34 of the said horseshoe shape etc. was set to below the thickness of the surrounding wall of the core material A, The protruding width is not particularly limited, and may be equal to or greater than the thickness of the peripheral wall of the core material A. However, from the viewpoint of workability in which the left and right end portions of the core material A are gripped by a chuck or the like, it is preferable that the protrusion width is equal to or less than the radius of the core material A.

  FIG. 10 shows a fifth embodiment of the support base of the present invention. In this support base, the mounting portion 51 on which the core material A [see FIGS. 3 (a) and 3 (b)] is mounted is a reinforcing frame in and between the connecting frame 2 that forms the short side of the virtual rectangle. 22 is formed in a substantially concave shape. And it forms so that the core material A may be located in the substantially concave shape. Except this, it is the same as the support stand of the said 1st Embodiment, and attaches | subjects the same code | symbol to the same part.

  In the fifth embodiment, as compared with the support base of the first embodiment shown in FIG. 1, there is no protrusion (mounting member 5) on the upper surface of the reinforcing frame 22, and accordingly, the roll body R [Refer to FIG. 3 (a), (b)] can be lowered and supported. Thereby, the gravity center of the support stand in the state where the roll body R is supported can be lowered, and the swing of the support stand can be reduced. As a result, the roll body R can be more reliably prevented from falling off. Moreover, since the height of the support base can be lowered by supporting the roll body R at a lower position as described above, when storing or transporting the support base, a space such as a storage place is provided. It can be used more effectively. Further, even when the core material A is placed on the placement portion 51, the amount of protrusion from the upper surface of the reinforcing frame 22 can be reduced, so that the height of the folded support base can also be lowered. Thereby, also when the support stand in the folded state is stored or transported, the space such as the storage location can be used more effectively.

  As yet another embodiment, the support frame 3 in each of the above embodiments may not have a substantially square shape but may have a linear shape. In this case, for example, the left and right ends of the core material A are supported and fixed by, for example, placing the left and right end portions of the core material A on the support frame 3 and then using the inverted U-shaped clamps.
