DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a side frame of a framework scaffold.

[0002]

2. Description of the Related Art Generally, as shown in FIG. 3, for example, a frame scaffold constructed on a construction site has a pair of parallel buildings 11 and a horizontal space 12 connecting upper ends thereof. After stacking them up and down and stacking them up and down to give the necessary structural strength using braces as necessary, a cloth plate 13 is mounted over the horizontal ground 12 that is lined up next to each other.
If necessary, the side frame 2 is connected to the adjacent building 11 on one side of the cloth plate 13.

As shown in FIG. 5, the side frame 2 has a pair of left and right vertical members 21 and a pair of upper and lower horizontal members 22, and a reinforcing plate for reinforcing these joints at four corners of the side frame 2. 123 and a reinforcing frame 24 for reinforcing the entire surface of the side frame 2.

[0006] As shown in FIGS. 6 and 7, the reinforcing plate 123 is welded to a semi-cylindrical vertical member connecting portion 124 welded to an end of the vertical member 21 and to an end of a horizontal member 22. A semi-cylindrical horizontal member connecting portion 125, and both connecting portions 124 and 125;
And a stay plate portion 126 connecting the two.

[0005]

When the side frames 2 are to be stored, the side frames 2 are laid horizontally and stacked up and down in multiple stages, or the side frames 2 are leaned in order.
Since the members are not positioned, it is difficult to arrange the side frames 2 in order and to stack or lean.

[0006] During transportation, a lateral inertial force acts on the side frames 2 stacked one above the other, so that a part of the side frames 2 may slide sideways and collapse. The present invention
The present invention has been made in view of the above circumstances, and it is an object of the present invention to provide a side frame of a framed scaffold that can position the side frames during storage or transportation.

[0007]

According to the present invention, in order to achieve the above object, for example, as shown in FIGS. 1 and 2, a vertical member 21 and a horizontal member 22 or one of them is attached to one surface of the side frame 2. The protruding receiving member 3 is fixed, and a V-shaped receiving groove 4 extending in parallel with the axis of the vertical member 21 or the horizontal member 22 is formed on one surface of the receiving member 3.

[0008]

According to the above construction, when the side frames 2 are overlapped with each other in the same direction, the vertical member 21 or the horizontal member 22 of one side frame 2 fits into the receiving groove 4 of the other side frame 2. Including
The two side members 2 are positioned so as not to move in the plane direction.

[0009]

DESCRIPTION OF THE PREFERRED EMBODIMENTS Embodiments of the present invention will be specifically described below with reference to the drawings. A framework scaffold to which an embodiment of the present invention is applied is, for example, as shown in FIG.
And a horizontal frame 12 that connects the upper ends of the two buildings 11 to each other, as well as assembling them in a plurality of stages in the vertical direction.
And the side frame 2 is attached to the side of the
Is attached. The side frame 2 has substantially the same height as the building 11, and is fixed to the building 11 such that the lower edge thereof is located at substantially the height of the center of the building 11 in each step.

As shown in FIG. 4, the side frame 2 comprises a pair of left and right vertical members 21, a pair of upper and lower horizontal members 22, and four corner members for reinforcing the connection between the four corners of the side frame 2. 23 and a reinforcing frame 24 for reinforcing the entire surface of the side frame 2.

Each of the side frames 21 is connected to three connecting fittings 5, 6, 7 at appropriate intervals in the vertical direction, and the connecting fittings 5, 6, 7 are provided on the building 11 in a receiving manner. The side frame 2 is fixed to the building 11 by connecting to a metal fitting.

As shown in FIGS. 1 and 2, each corner member 23 has a portion connected to overlap with the vertical member 21 and a portion connected to overlap with the horizontal member 22 on one side of the side frame 2, respectively. It is bent into a protruding M-shape. The metal fitting 3 for receiving the vertical member 21 or the horizontal member 22 of the other side frame 2 at the portion bent in the M shape.
The M-shaped central groove forms a V-shaped receiving groove 4 extending in parallel with the axis of the vertical member 21 or the horizontal member 22.

When the side frames 2 are overlapped with each other in the same direction, the vertical member 21 or the horizontal member 22 of one side frame 2 fits into the receiving groove 4 of the other side frame 2, and the side frames 2 It is positioned so as not to move in the plane direction.

As a result, during storage, the vertical member 21 or the horizontal member 22 of the other side frame 2 is inserted into the receiving groove 4 of one side frame 2.
And the side frames 2 are positioned relative to each other, so that the side frames 2 can be easily stacked in order and leaned.

Also, during transportation, even if a lateral inertial force acts on the side frames 2 stacked one above the other, the side frames 2 position each other, so that a part of the side frames 2 slides sideways. And the occurrence of load collapse due to this can be prevented.

In the above embodiment, it is possible to form the corner member 23 and the receiving member 3 separately from each other, but as described above, the corner member 23 is press-formed and the corner member 23 and the receiving member 3 are integrated. In this case, it is not necessary to increase the number of parts, and it is possible to reduce parts manufacturing costs, parts assembly costs, and the like, thereby reducing costs.

In the above-described embodiment, it is possible to form the receiving fitting 3 on only one pair of the two pairs of corner members 23 located diagonally to each other. In the case where the receiving fitting 3 is formed on the base member 23, it is advantageous in that the type of the corner member 23 can be one type to reduce the manufacturing cost of the parts, and that the side frames 2 can be stably stacked and lean.

[0018]

As described above, according to the present invention, the vertical member and the horizontal member of the side frame or one of them is provided with the receiving member projecting from one side of the side frame, and the vertical member or the one side of the receiving member is provided. Since a V-shaped receiving groove extending parallel to the axis of the horizontal member is formed, when the side frames are overlapped with each other in the same direction, the vertical member or the horizontal member of one side frame is inserted into the receiving groove of the other side frame. The two frames are positioned so that they do not move in the plane direction.

As a result, at the time of storage, the vertical frame or the horizontal member of the other side frame is inserted into the receiving groove of the one side frame to position the side frames with each other, so that the side frames can be easily neatly arranged. Can be stacked and leaned.

Also, during transportation, even if a lateral inertial force acts on the side frames stacked one above the other, the side frames position each other, so that a part of the side frames may slide or The occurrence of load collapse can be prevented.

In the present invention, in particular, there is provided a reinforcing plate for reinforcing the joining between the vertical member and the horizontal member, and the reinforcing plate is bent into an M-shape at a place where the reinforcing plate and the vertical member or the horizontal member overlap, and the receiving bracket is provided. Is formed, it is not necessary to increase the number of parts, and it is possible to reduce costs by reducing parts manufacturing costs, parts assembly costs, and the like.
