Description

  The present invention relates to a container transport jig for flat glass, and more particularly to a container transport jig used when housing and transporting plate glass for building materials in a container.

  Some large plate glass for building materials has a weight of about 1 to 2 tons when, for example, dozens of plate glasses are stacked and bundled as one unit. Usually, a plurality of units are put together with a polystyrene foam cushioning material between each unit, and the unit is slanted and fixed to the inner wall of the container, and the container is transported by ship, truck, aircraft or the like.

  In container transportation, when a sheet glass is slanted against the inner wall of the container, a space with a right-angled triangle is formed between the container inner wall and the sheet glass may be bent and damaged by vibration during transportation. Moreover, it is necessary to fix firmly so that a plate glass may not move within a container by the inertial force given from a container during transport. Therefore, conventionally, a transportation jig has been used to fill a space formed between the plate glass and the inner wall of the container to suppress the bending of the plate glass. This transport jig is made of steel made of square pipe, angle steel, etc., and a plurality of trapezoidal column members whose longitudinal sections are cut at the top of a right triangle are arranged at intervals, and between each column member A plurality of beam members are connected to form a frame.

  The transportation jig formed as described above is set in contact with the inner wall of the container with the vertical triangular slope as the front surface and the vertical surface as the back surface, and the plate glass is put on the front surface via a cushioning material, The transport jig and the plate glass are fixed and secured with a steel band or the like. In addition, a base member having a length corresponding to the thickness of a plurality of units of plate glass is arranged at the lower end portion of the column member of the transportation jig, and the transportation jig is fixed to the floor surface of the container via this base member. ing. Thereby, damage of a large sized plate glass can be prevented and it can convey safely. In addition, a tension rod or the like is applied to the surface of the plate glass so that the plate glass secured to the transport jig does not fall to the opposite side of the inner wall of the container.

  Instead of leaning the plate glass against the inner wall of the container, the plate glasses can be leaned against each other at the center position of the container. In this case, a transportation jig having an isosceles triangular longitudinal section is used, but it is formed of a steel square pipe or angle steel.

  However, the above-described conventional container transport jig for plate glass is heavy because it is made of steel, and the work of carrying it into the container must be performed using a heavy machine such as a forklift. In addition, since the container transportation jig is disposable, after loading and unloading the plate glass at the site, the steel transportation jig must be cut and disassembled and then disposed of. Therefore, since the conventional container transportation jig for flat glass is made of heavy steel, transportation costs such as man-hours for loading into the container, costs for heavy machinery, disposal costs, etc. are incurred. There is a need for a container transport jig that can reduce costs.

  On the other hand, Patent Document 1 proposes a technique in which a thin plate such as a sheet glass is stood against a vertically placed support member and packed. That is, a support member for a glass plate in which a trapezoidal column member whose longitudinal section is cut at the top of a right triangle is formed by corrugated cardboard, and an armrest formed in an L shape by corrugated cardboard is fixed to both sides of the lower end of the column member. Proposed. According to this, since the support member of a glass plate is formed with the corrugated cardboard, there exists an advantage that a weight is light. Therefore, if cardboard can be used as a container transportation jig for large flat glass for building materials, it is light in weight and can be easily disassembled by cutting or the like, so that it can be disposed of. Can be expected to do.

JP 2009-274732 A

However, the glass plate supporting member described in Patent Document 1 is used for transporting a relatively small and lightweight glass plate used for liquid crystal display glass and the like. Since the weight of the plate is so light that it cannot be compared, there are the following problems to be solved.
That is, since the trapezoidal column member of Patent Document 1 is formed by bending cardboard into a cylindrical shape, the column member is not crushed when it is covered with a bundle of large plate glass for building materials. In addition, since the armrest member is formed by laminating a plurality of corrugated cardboard sheets, it is recognized that the armrest member has a certain strength. However, a bundle of large plate glass for building materials can reach several to several tens of tons. Therefore, even if a plurality of cardboard sheets are stacked, they are crushed and are not useful.

  The problem to be solved by the present invention is to realize a container transport jig that is lightweight, easy to carry in and assemble into a container, and easy to disassemble and dispose of after use.

  In order to solve the above-mentioned problem, the present invention is a container transport jig for building glass, comprising a plurality of column members and a plurality of beam members for connecting the column members, A bottom surface installed on the floor surface of the container, at least one front surface formed to be inclined so that the plate glass is leaned thereon, and a pair of side surfaces extending vertically from the bottom surface, and a plurality of corrugated cardboard plates The beam member is formed by laminating a plurality of corrugated cardboard plates in the longitudinal direction, and the beam member is formed by penetrating both side surfaces of the column member. A notch or opening into which the member is fitted is formed.

  In this case, the pillar member is formed in a trapezoidal shape in which a cross section parallel to the side surface is cut at the top of a right triangle, the trapezoidal inclined surface is the front surface, and the vertical surface facing the front surface is the back surface. It can be said that. In this case, the column member is formed with a plurality of U-shaped cuts into which the beam member is fitted into at least one of the front surface and the back surface, and the beam member is formed in the portion fitted into the cut of the column member. A U-shaped notch corresponding to the width of the member may be formed. Thereby, the back surface of the column member can be placed in contact with the inner wall of the container, and the load of the plate glass leaning on the entire surface of the column member can be firmly supported by the inner wall of the container.

  Further, the column member can be formed into a trapezoidal shape in which the cross section parallel to the side surface is cut off from the top of an isosceles triangle by changing the trapezoidal shape to the top of a right triangle. Thereby, a trapezoid-shaped inclined surface is used as the front surface, and the plate glass can be used leaning from both sides of the column member.

  In particular, according to the present invention, since the container transport jig is formed of a cardboard board, the weight can be remarkably reduced as compared with that made of steel. In particular, the column member was formed by laminating a plurality of cardboard plates in parallel to the side surface of the column member. That is, by making the direction in which the corrugated core corrugation can be seen coincide with the direction in which the plate glass is applied with a load, the strength of the column member can be exerted, and the load resistance according to the number of laminated sheets can be provided. In addition, since the column member and the beam member can be connected by a U-shaped notch of the column member or by fitting the beam member into the opening, assembly and disassembly are easy. For these reasons, since the container transportation jig can be disassembled and loaded when loaded into the container, it can be easily loaded and assembled manually without using heavy machinery. Similarly, even after loading and unloading plate glass at the site, it can be easily disassembled and carried out manually, and can be easily disposed of.

  In the present invention, the beam member can be formed by laminating a plurality of cardboard plates extending in the longitudinal direction. The column member and the beam member are connected by a cut portion of the column member. Note that the beam member is formed by forming a U-shaped cut corresponding to the width of the column member at a portion to be fitted into the column member, so that the strength of the connecting portion can be increased.

  Further, the corrugated board is formed by sandwiching the corrugated core between the liners, and the column member is formed by stacking the corrugated board so that the corrugated core of the corrugated board is visible from the front side. . As a result, it is possible to increase the compression resistance strength of the surface of the column member on which the plate glass is leaned and to increase the strength in the stacking direction of the cardboard plates.

Moreover, the base member which fixes a pillar member to the floor surface of a container can be provided.
The base member may be a pair of wooden square members arranged on the floor surface of the container across the side surface at the lower end of the column member, and a wooden plate member fixed over the upper surfaces of the pair of square members. . Thereby, even if it puts the bundle | flux of the large sized plate glass for building materials from several tons to several tens tons, it can stand against without collapsing.

  ADVANTAGE OF THE INVENTION According to this invention, the container transport jig | tool which is lightweight and easy to carry in and assemble to a container, and can be easily disassembled and disposed of after use can be realized.

It is the perspective view which looked at one pillar member of Drawing 1 from back. It is a perspective view showing the detailed structure of the beam member of FIG. It is a perspective view of the part which shows the detailed structure of the cardboard board which forms the pillar member of FIG. It is an elevation view which shows the state which contact | abutted and assembled the container transport jig of FIG. 1 to the inner wall of a container. FIG. 6 is a plan view of FIG. 5. It is sectional drawing in line AA of FIG. It is sectional drawing of the container transport jig of other embodiment of this invention.

  Hereinafter, an embodiment of a container transportation jig to which the present invention is applied will be described with reference to FIGS. 1 to 8.

(Embodiment 1)
FIG. 1 shows a perspective view of the container transport jig of the present embodiment. As shown in FIG. 1, the container transport jig 1 includes a plurality of column members 2 and a plurality of beam members 3 that connect the column members 2 to each other. FIG. 1 shows an example in which two sets of container transportation jigs 1 are connected by a plurality of beam members 3.

  The column member 2 has a bottom surface 4 which is a bottom when standing and a pair of side surfaces 5 extending vertically from the bottom surface 4, and a trapezoidal shape in which a cross section parallel to the side surface 5 is cut at the top of a right triangle. The trapezoidal inclined surface is the front surface 6, the vertical surface is the back surface 7, and a plurality of cardboard plates 8 are laminated in parallel to the side surface 5. Further, the inclination angle of the column member 2 can be changed depending on the size and weight of the plate glass to be leaned.

  The beam member 3 has a rectangular parallelepiped shape, and is formed by laminating a plurality of cardboard plates 8 extending in the longitudinal direction.

  As shown in FIG. 2, a plurality of cuts 9 having a U-shape when viewed from the side surface 5 are formed on the front surface 6 side of the inclined surface of the column member 2. The plurality of cuts 9 are provided corresponding to the number of the plurality of beam members 3 to be fitted through the both side surfaces 5 of the column member 2.

  As shown in FIG. 3, the beam member 3 may be formed with a plurality of U-shaped notches 10 corresponding to the width of the column member 2 in the portion fitted into the notch 9 of the column member 2. . The number of the notches 10 corresponds to the number of the notches 9 of the pillar member 2 to be connected. Since it comprises in this way, since the pillar member 2 and the beam member 3 mutually mesh | engage and connect with the other member by a notch part, the intensity | strength of a connection part can be raised.

  The notch 9 of the column member 2 can also be provided on the back surface 7 of the column member 2. Furthermore, an opening (through hole) may penetrate the column member 2.

  The corrugated board 8 is formed by sandwiching a corrugated core 11 between liners 12. The column member 2 is formed of laminated corrugated cardboard in which corrugated cardboard plates 8 are combined and laminated in a plurality of layers. Further, the corrugated cardboard 8 is formed so that the corrugation of the core 11 is visible from the front surface 6 side. That is, as shown in FIG. 4, the end surface on which the corrugation of the core 11 of the cardboard plate 8 appears is the front surface 6 of the column member 2. Since the corrugated cardboard 8 configured in this way has high compression resistance in a direction orthogonal to the stacking direction, it can sufficiently support the leaning load of the plate glass applied to the front surface 6. Moreover, the strength in the stacking direction of the cardboard plates 8 can be increased by combining the adjacent cardboard plates 8 with each other. The cardboard board is made of a resource-recyclable material, and adopts water-resistant paper and corrugated cardboard that has been subjected to waterproof impregnation treatment. Thereby, since a corrugated cardboard board can be reused, cost can be reduced. Further, in the case of marine transportation, the strength of the transportation jig can be maintained even if moisture or condensation occurs.

  As shown in FIG. 5, the container transport jig 1 includes a base member 15 that fixes the column member 2 to the floor surface 14 of the container 13. In addition, the oblique line in FIG. 5 does not represent a cross section, but is described for easy understanding of the distinction between members. The base member 15 has a pair of wooden square members 16 disposed on the floor surface 14 of the container 13 across the side surface 5 at the lower end of the column member 2, and a wooden plate member fixed across the upper surfaces of the pair of square members 16. 17. At this time, it is preferable that the board | plate material 17 uses the plywood according to export restrictions. On the upper surface of the plate member 17 of the base member 15, a plurality of rubber cushioning members 18 are provided in the extending direction of the square member 16. The material of the buffer material 18 is not limited to the rubber plate as long as the buffer effect can be exhibited.

  A procedure for installing the container transportation jig 1 of the present embodiment configured as described above in a container will be described with reference to FIGS.

  First, as shown in FIG. 6, the back surface 7 of the column member 2 is brought into contact with the inner wall surface 19 of the container 13. In addition, the oblique line in FIG. 6 does not represent a cross section, but is described for easy understanding of the distinction between members. Next, as shown in FIG. 7, a base member 15 is installed to fix the column member 2 to the floor surface 14 of the container 13. In FIG. 7, the plate glass unit 20 is complicated, and thus hatching is omitted. The base member 15 has a pair of wooden square members 16 disposed on the floor surface 14 of the container 13 across the side surface 5 at the lower end of the column member 2, and is fixed to the wooden plate member 17 across the upper surfaces of the pair of square members 16. . At this time, the base member 15 is made to have a length that matches the thickness of a plurality of sheet glass units 20 that are stacked and bundled as a unit. After the base member 15 is installed, a plurality of rubber cushioning materials 18 are installed on the upper surface of the plate member 17 in the extending direction of the square member 16. In this embodiment, ten units of plate glass are set as one unit, and the number of rubber plates is two. However, the number of plate glasses and the number of rubber plates in one unit are not limited thereto.

  And the beam member 3 is inserted in the notch 9 of the column member 2, and as shown in FIG. 5, the some column member 2 and the some beam member 3 are connected, and the one container transport jig | tool 1 is assembled. In this embodiment, the three column members 2 and the two beam members 3 constitute one container transportation jig 1, and two container transportation jigs 1 are arranged side by side in the longitudinal direction of the container 13. They are connected by two beam members 3. Needless to say, the number of the column members 2 and the beam members 3 of the container transport jig 1 varies depending on the size and weight of the standing plate glass. Further, the plate glass unit 20 may be leaned against each of the two container transport jigs 1 of the present embodiment. However, when the size of the plate glass is large, it is leaned over the two container transport jigs 1. Can be transported.

  As shown in FIG. 7, the plate glass unit 20 is placed on the cushioning material 18 on the upper surface of the base member 15, and the plate glass unit 20 is inserted into the column while sandwiching a polystyrene foam plate spacer between the units. It leans against the front surface 6 of the member 2. Next, a plate-shaped glass retainer 21 is pressed against the front surface of the plate glass unit 20 at a position corresponding to the position of the column member 2, and the entire steel band 22 including the plate glass unit 20 is positioned at the position of the column member 2 and the glass retainer 21. Bundle it up and tie it up. Then, after the plate glass units 20 are erected on both inner wall surfaces 19 of the container 13, the plate glass units 20 on both sides are pressed against the inner wall surface 19 side of the container and fixed with the steel sticks 23 through the glass holders 21. . Thereby, even if the container 13 is shaken during transportation, the plate glass unit 20 can be prevented from falling over to the opposite side of the inner wall surface 19, so that the sheet glass can be prevented from being damaged and transported safely.

  Further, as shown in FIGS. 5 and 6, the lower end portion of the plate glass unit 20 leaning on one container transport jig 1 is fixed by sandwiching the inner wall surface 19 from the front and rear with the glass fixing wood 24. . Thereby, it is possible to prevent the plate glass unit 20 from moving in the container 13 due to the inertial force applied from the container 13 during transportation.

  Further, the column member 2 fitted with the beam member 3 does not support all the weight of the plate glass unit 20 but serves as a cushion material when the plate glass unit 20 is leaned against the inner wall surface 19 of the container 13. Have. In addition to this, the column member 2 is formed by laminating the corrugated cardboard 8 in parallel with the side surface 5, and the liner 12 surface of the corrugated cardboard 8 is disposed in the direction in which the counter load of the plate glass unit 20 is applied. . For this reason, even if the container transport jig 1 is formed of the corrugated cardboard 8, the front surface in the direction orthogonal to the stacking direction of the corrugated cardboard 8 has high compressive strength, so that the weight of the flat glass unit 20 can be supported. it can.

In addition, according to the present embodiment, the material of the column member 2 and the beam member 3 of the container transport jig 1 is the corrugated cardboard 8, and they are configured so as to be fitted.
The weight is lighter than that made of steel, and the column member 2 and the beam member 3 can be easily assembled or disassembled without using a tool. Thereby, carrying in and assembling of the container transport jig into the container is easy, and the work of disassembly and disposal after use is facilitated. In view of reducing the burden on the operator, it is desirable that the weight of each member is 5 kg or less, for example.

(Embodiment 2)
Next, FIG. 8 shows another embodiment of the present invention. The difference between this embodiment and the first embodiment is that the column member is formed in a trapezoidal shape in which the cross section parallel to the side surface is cut off from the top of an isosceles triangle, and the trapezoidal inclined surface is the front surface It is in. Since other points are the same as those of the first embodiment, description thereof is omitted. In addition, in FIG. 8, since it became complicated about the unit 20 of plate glass, hatching was abbreviate | omitted.

  As shown in FIG. 8, in this embodiment, a trapezoidal container transportation jig 25 having a cross section cut off at the top of an isosceles triangle is installed at the center of the container 13. Accordingly, the plate glass units 20 are formed so as to be inclined to each other.

  With this configuration, according to this embodiment, it is easy to carry in and assemble the same container transportation jig as in Embodiment 1, and the work of disassembly and disposal after use The effect that it becomes easy can be produced. Further, since the number of plate glass units laid on one container transportation jig is doubled as compared with the first embodiment, the number of container transportation jigs can be reduced.
