Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a material transport container for building materials.

[0002]

[Prior Art]

 Conventionally, when using long construction materials such as pillars, beams, and electric wire covers, each material was transported to the construction site while being stored in the package, and the material was taken out from the package at the site.

[0003]

[Problems to be solved by the device]

 Therefore, after the materials are taken out at the site, the packaging is no longer needed and waste material is generated, which is troublesome to process, and the materials are stored in the package, which makes them bulky and large amounts of material are needed at a time. I couldn't carry the materials.

In view of the above, the present invention aims to provide a material transport container that does not cause bulkiness to transport various materials to a construction site and does not cause waste materials such as packages at the site. To do.

[0005]

[Means for Solving the Problems]

 In order to achieve the above-mentioned object, the material transport container according to the present invention has a foldable structure in which the bottom wall is foldable in an inverted V shape and can be deployed in a horizontal plane, and is pivotally connected in the front-rear center. And the left and right side walls can be folded in a V shape in plan view and can be vertically expanded, and have a folding structure that is pivotally connected at the front-rear center; the whole is folded so that the front and rear walls overlap. It was made possible.

[0006]

[Action]

 The bottom wall is expanded horizontally and the left and right side walls are expanded vertically to accommodate building materials. After taking out all the building materials at the site, fold the bottom wall into an inverted V shape and the left and right side walls into a V shape in plan view. Then, the front wall and the rear wall gradually come close to each other, and finally the front wall and the rear wall are overlapped with each other and the whole is folded.

[0007]

【Example】

 Hereinafter, the present invention will be described in detail with reference to the drawings illustrating an embodiment.

FIG. 1 shows an embodiment of a material transport container according to the present invention. The material transport container comprises a front wall 1 and a rear wall 2 which are frame bodies 3 and 3 having a substantially rectangular shape in front view, and a front and rear wall. Left and right side walls 4 and 4 that are pivotally connected at the center and can be folded in a V shape in plan view, and bottom walls that are pivotally connected at the front and rear centers and can be folded in an inverted V shape in side view 5 is provided.

The frame bodies 3 and 3 respectively include left and right vertical column members 6 and 6, horizontal beam members 7 that are vertically extended in parallel with the vertical column members 6 and 6, and upper and lower portions. The horizontal beam members 7 and the reinforcing members 8 that are bridged in a zigzag shape between the horizontal beam members 7 and the four vertical column members 6 of the front wall 1 and the rear wall 2 have lower ends respectively. It projects downward and forms the legs 10.

Further, as shown in FIGS. 2, 3, 4 and 5, the left and right side walls 4, 4 respectively have two rectangular lattice frames 11, 11. The rectangular lattice frames 11, 11 are formed by welding metallic wire rod-shaped members 9 ... In a lattice shape. The adjacent one side and one side of the two rectangular lattice frames 11 and 11, that is, the front and rear centers of the side walls 4 and 4, are respectively pivoted by a hinge 12 and parallel to the side. The other side, that is, the vertical end sides before and after the side walls 4 and 4, are pivotally supported by hinges 13 and 13 along the vertical members 6 and 6 of the front and rear frames 3 and 3, respectively. Be worn. The side walls 4 and 4 project outward in the left and right directions so that they can be folded into a V-shape in plan view at the center in the front-rear direction and can be deployed in a vertical plane.

Next, the bottom wall 5 has two elongated rectangular grid frames 14, 14 formed in the same manner as the rectangular grid frames 11, 11 of the side wall 4. The adjacent long sides of the two lattice frames 14, 14, that is, the front-rear center of the bottom wall 5 are pivotally connected by a hinge 15 and the other side parallel to that side. That is, the front and rear horizontal edges of the bottom wall 5 are pivotally attached by hinges 16 along the horizontal beam members 7, 7 below the front and rear frames 3, 3, respectively. However, the bottom wall 5 is foldable in an inverted V shape in a side view and is also deployable in a horizontal plane.

Therefore, the material transport container of this embodiment has a rectangular parallelepiped shape as shown in FIG. 1 in the unfolded state, and a front wall 1 and a rear wall 2 as shown in FIG. 6 in the folded state. When overlapped, the whole becomes one plate.

However, in order to use the material transport container of this embodiment, as shown in FIG. 1, with the side walls 4, 4 and the bottom wall 5 expanded, various materials are stored and transported to the site. .. Then, all materials are unloaded at the site.

Next, the side walls 4 and 4 and the bottom wall 5 are folded and brought home, and stored as they are in a material storage warehouse or the like. Then, when it is used again, it may be in an expanded state.

Therefore, since the material transport container of this embodiment can be easily and compactly folded, it can be easily brought home without being bulky and can be stored without becoming bulky. Furthermore, it can be used again and again because it can be deployed again.

7 and 8 schematically show another embodiment of the material transport container according to the present invention, in which the left and right side walls 4 and 4 are folded inward, respectively. It is composed. Then, in order to prevent the left and right edges of the bottom wall 5 from hitting the central portions of the side walls 4 and 4 in the front-rear direction, the side portions of the central portions of the side walls 4 and 4 in the folded state (in FIG. 8) are more than the side parts of the central portions in the front-rear direction. It is located slightly inward.

With the above configuration, the left and right side walls 4 and 4 do not project outward in the folded state, and can be folded more compactly.

In addition to the above-described embodiment, the present invention can be freely changed in design without departing from the gist of the present invention. For example, the front and rear 1 and the rear wall 2 each have one plate material or mesh material. It is also preferable that the left and right side walls 4 and 4 and the bottom wall 5 are formed of two plate members or mesh members and can be folded in a V shape.

[0019]

[Effect of the device]

 Since the present invention is configured as described above, it has the following effects.

If the left and right side walls 4 and 4 and the bottom wall 5 are in an unfolded state, various materials can be directly stored and unloaded, and in this state, they can be loaded onto a truck or other transportation vehicle and transported to the construction site. .. After the materials are loaded and unloaded, they can be easily folded so that the front wall 1 and the rear wall 2 overlap each other, and can be stored in a material storage warehouse or the like without becoming bulky. In addition, no waste materials such as packages will be generated on-site. Furthermore, since the side walls 4, 4 and the bottom wall 5 can be unfolded again, they can be used any number of times.
