Description

  The present specification discloses a structure in which a plurality of long thick plates are assembled and connected.

  Steel materials called angles are widely used. The angles are long, L-shaped in cross-section, and in various combinations provide a framework structure such as a shelf.

In order to increase the strength, a steel material having irregularities formed on each side forming an L-shape has been developed. As shown in FIG. 2, the steel material 1 is long, and a mountain-shaped ridge 4 a is formed in a widthwise middle portion of one side 4 extending to one side from a bending line 2 extending in the widthwise center in the lengthwise direction. The other side 6 extending from the bending line 2 to the other side has a chevron-shaped ridge 6a formed in the middle portion in the width direction. The ridges 4a and 6a extend in the longitudinal direction. The one side 4 and the other side 6 intersect at a right angle at the bending line 2 if there are no ridges 4a, 6a, and have an L-shape.
When the tops of the three-dimensional object are formed by overlapping the ends of the steel material 1, the existence of the ridges 4a and 6a cannot be ignored. When the ends are overlapped, as shown in the cross section of FIG. 1, the cross section is L-shaped and the thickness of each side is t. A relationship is required. In this specification, a material whose cross section is an L-shaped long material and whose thickness t on each side is large is referred to as a long thick plate material. It can be said that the steel material 1 is substantially a long thick plate material having a thickness t. The thickness of the plate material itself constituting the steel material 1 is so thin as to be negligible relative to the thickness t.

  When the thickness t is large, it is difficult to form an apex of a three-dimensional object by overlapping and connecting end portions of a plurality of long thick plate members. For example, when three long thick plates are overlapped in a posture extending in the front-rear direction, a posture extending in the up-down direction, and a posture extending in the left-right direction, the thickness is a problem, and the end members are connected. It will be difficult to do. When a through hole is formed in the vicinity of the end portion and the bolt is connected to the through hole, if the thickness t is large, the position of the through hole becomes inconsistent, and the position of the through hole is changed for each long thick plate material. If you do not change it, you will not be able to connect. It becomes difficult to prepare a plurality of long thick plates with through holes in advance and to connect them.

  In addition, when forming a large-scale structure having a continuous rectangular parallelepiped shape, a structure in which six long thick plates extending upward, left, front, right, rear, and downward from one vertex are required. Is done. In this specification, this is referred to as an orthogonal six-axis structure. In the conventional technology, it is difficult to realize an orthogonal six-axis structure by combining six long thick plate members having an L-shaped cross section. Even more, a large-scale structure in which the orthogonal six-axis structure is continuous is more difficult. Could not be realized.

  One example of a commonly used truss structure includes a joint that connects eight steel materials. That is, four horizontal long thick plate members extending from the joint in the left, front, right, and rear directions, and four inclined lengths extending in the left front upper direction, the right front upper direction, the right rear upper direction, and the left rear upper direction. A joint for connecting the shank is used. The above joint could not be obtained from a long thick plate material having an L-shaped cross section.

In the present specification, at least a rectangle formed by connecting a pair of front and rear long thick plates extending in the front-back direction and a pair of left and right long thick plates extending in the left and right direction, and four upper and lower long thickness members extending downward from four vertices of the rectangle. Disclosed is a rectangular parallelepiped structure in which plate members are connected. In this specification, two sides forming an L-shape are referred to as “one side” and “the other side”.
In the structure disclosed in this specification, one side of the front and rear long plank is inside the upper and lower long plank, and one side of the upper and lower long plank is inside the left and right long plank, One side of the left and right long thick plate is inside the front and rear long thick plate, the other side of the front and rear long thick plate is outside the left and right long thick plate, and the other side of the left and right long thick plate is It satisfies the relationship that it is outside the upper and lower long thick plates and the other side of the upper and lower long thick plates is outside the front and rear long thick plates.

  In the above relationship, the three long thick plate members are arranged in a rotationally symmetric relationship, and the three long thick plate members can be overlapped in an orthogonal posture. In this specification, "the first long thick plate is located inside the second long thick plate, the second long thick plate is located inside the third long thick plate, Is located inside the first long plank, or "the first long plank is located outside the third long plank, and the third long plank is the second long plank." And the second long plank is positioned outside the first long plank "is referred to as rotational symmetry. In this specification, the inside of a 90-degree angle range formed by two sides forming an L-shape is called an inside, and the inside of a 270-degree angle range formed by two sides is called an outside. The structure realized by the technology of the present specification, when focusing on one side, the front and rear long thick plates are located inside the upper and lower long thick plates, and the upper and lower long thick plates are inside the left and right long thick plates. The left and right long thick plate is located inside the front and rear long thick plate, and if attention is paid to the other side, the front and rear long thick plate is located outside the left and right long thick plate. The plate material is located outside the vertically long thick plate material, and the vertically long thick plate material is located outside the front and rear long thick plate material, and satisfies rotational symmetry.

In the above structure, a rectangular shape is formed by the pair of front and rear long thick plates and the pair of left and right long thick plates. When the rectangle is viewed in a plan view, it is preferable that the long thick plate members are superimposed on a line bisecting the long thick plate members in the longitudinal direction while maintaining a line-symmetric relationship. In this case, three long thick plates overlap at all vertices while satisfying rotational symmetry. In addition, a relationship is obtained in which all upper and lower long plate materials extend perpendicular to the rectangle. The structure can be assembled in such a manner that all the long plank materials are not twisted.
In the present specification, a structure in which the lower ends of upper and lower long plates are open, such as a four-legged desk, is also referred to as a rectangular parallelepiped structure. This is because when the lower ends of the four upper and lower long thick plates are grounded, the structure has a rectangular parallelepiped appearance. A pair of front and rear long thick plates and a pair of left and right long thick plates are connected to the lower ends of the four upper and lower long thick plates to form a rectangular parallelepiped structure formed by six rectangles. Can also.

  In order to realize a large-scale structure (for example, a structure having a plurality of spans and a plurality of floors), six long thick plate members extending from the origin in six orthogonal axes (that is, in six directions of up, down, left, right, front and rear) are assembled. It is necessary to realize an orthogonal six-axis structure. In the case of a long thick plate having an L-shaped cross section, it is difficult to realize an orthogonal six-axis structure because the thickness is an obstacle.

In this specification, one side of the upper long plank is inside the left long plank, one side of the left long plank is inside the upper long plank, One side of the lower long plank is inside the lower long plank, one side of the lower long plank is inside the front long plank, and one side of the right long plank is the rear long plank Inside, the one side of the rear long plank is inside the right long plank, the other side of the upper long plank is outside the rear long plank, the rear long plank The other side of the right long plank is outside the upper long plank, the other side of the right long plank is outside the lower long plank, and the other side of the lower long plank is the right long plank And the other side of the front long plank is outside the left long plank, and the other side of the left long plank is outside the front long plank. Assemble a long thick plate.
In this case, a six-axis structure can be realized while satisfying rotational symmetry. This orthogonal six-axis structure can be continuous in a required number in the vertical, horizontal, and front-rear directions, thereby providing a large-scale structure.

Instead of the above, one side of the upper long plank is inside the left long plank, one side of the left long plank is inside the upper long plank, and the front long plank One side of the lower long plank is inside the lower long plank, one side of the lower long plank is inside the front long plank, and one side of the right long plank is the rear long plank Inside, and one side of the rear long plank is inside the right long plank, the other side of the upper long plank is inside the rear long plank, and the rear long plank The other side of the right long plank is inside the upper long plank, the other side of the right long plank is inside the lower long plank, and the other side of the lower long plank is the right long plank The other side of the front long plank is inside the left long plank, and the other side of the left long plank is inside the front long plank. 6 long strips extending in the front-back direction Each end of the plate may be connected.
This can also realize a six-axis orthogonal structure. This orthogonal six-axis structure can also be continued in a required number in the vertical, horizontal, and front-rear directions, thereby providing a large-scale structure.

  According to the technique described in this specification, various structures can be obtained by assembling a plurality of long thick plate materials each having a simple shape and a uniform shape.
