Description

[Detailed Description of the Invention] The present invention relates to an assembly type frame. At present, stands (frames, etc.) for metal products, such as frames for steel cabinets, cable racks, etc., are made by welding and assembling steel plate base plates. However, this is very inconvenient for transportation, storage, and storage. The present invention provides an assembly type frame which can be disassembled into individual base plates for storage and transportation, and can be easily assembled on site when used.

The assembly type frame according to the present invention will be explained by taking a cable rack as an example. FIG. 1 is a perspective view showing the structure of a conventional cable rack. Two horizontal base plates 1 on the left and right forming an upper edge 2 bent outward and a lower edge 3 bent inward are welded together with vertical base plates 4, 4', 4'', each having a U-shaped cross section. Connected long frame 5
is configured. Section 6 is a welded portion between the horizontal base plate 1 and the vertical base plate 4. The structure in which the bent edges 2 and 3 are provided on the upper and lower sides of the horizontal base plate 1 and the U-shaped cross section of the vertical base plate 4 increase the bending stress of each and create a durable frame. The bent edges 2 and 3 of 1 are used as hanging edges from the girders of the building or attachment edges to the floor girders, and the cables are placed and laid on the base plate 4.

The frame according to the present invention has a vertical base plate having a U-shaped cross section like the conventional type described above, like the base plate 40 (half of the base plate is shown) shown in an enlarged perspective view in FIG. (The side faces facing both horizontal base plates) are also covered with folded closing pieces 41. That is, the bent closing piece 41 has a box shape, and an upper semicircular notch 42 is cut in the center thereof. Further, as shown in an enlarged perspective view of a part of the horizontal base plate in FIG. 3, a circular hole 12 is located at a position where the center of the upper semicircular shape of the groove 42 of the vertical base plate 40 of the horizontal base plate 11 coincides with the center of the groove. wear it. In this way, as shown in FIG. 2, the vertical base plate 40 and the groove 42 are aligned with the circular hole 12 of the horizontal base plate 11, and the synthetic resin as shown in the enlarged perspective view in FIG. The horizontal base plate 11 and the vertical base plate 40 are fixed by press-fitting a latching pin 7 made of an elastic material such as the above. This state is shown in FIG. 5 as an enlarged cross-section of a portion of the pin 7 of the horizontal base plate 11 and the vertical base plate 40. As shown in the figure, the pin 7 is a latching pin 72 whose tip forms a tapered part 71, and the front thereof has a minimum diameter part 73 having a slightly smaller diameter than the diameter of the latching part 72. A small-diameter portion 74 having a slightly larger diameter than the diameter of 72, and a frontmost portion serving as a large-diameter bed plate presser head 75. That is, the minimum diameter portion 73 fits into the upper part of the groove 42 of the vertical base plate 40, and the small diameter portion 74 fits into the circular hole 12 of the horizontal base plate 11, so that the horizontal base plate 11 and When assembling with the vertical base plate 40, the groove 42 of the vertical base plate 40 is aligned with the circular hole 12 of the horizontal base plate 11, and the tip tapered portion 71 of the pin 7 is pushed in from the outside of the horizontal base plate. In this case, the end hooking part 72 of the pin 7 has a larger diameter than the groove 42 of the vertical base plate 40, but since it is an elastic pin, if it is press-fitted, the plate material of the base plate 4 is not that thick, and The small passage diameter part is a groove (longitudinal notch) instead of a circular hole.
Therefore, the latching portion 72 is distorted in the longitudinal direction of the groove, and the minimum diameter portion 73 fits into the groove, and the small diameter portion 72 is distorted in the longitudinal direction of the groove.
The four parts fit into the circular holes 12 of the horizontal base plate 11, and the horizontal base plate and the vertical base plate are latched and fixed.

As mentioned above, the pin 7 is made of an elastic material such as synthetic resin, but if particularly strong strength is required, it may be made of metal and coated with synthetic resin. In this case, by thickening the coating on the tip end hooking portion 72 of the pin, the strength can be increased while facilitating the assembly operation.

Another embodiment of the present invention is shown in a perspective view in FIG. 6, in which the assembly type pedestal according to the present invention is used as a frame such as a steel cabinet. As shown in the figure, the vertical base plates 31, 31 are assembled on the inside of both ends of the horizontal base plates 21, 21 using a rectangular frame base, and the latching pins 7 (same pins as shown in FIG. 4 above) are used as in the above embodiment. Both base plates 21,
31 is fixed. The horizontal base plate 21 is the seventh
As shown in the figure, the vertical base plate 31 is L-shaped in cross section with the bent sides 23 bent at right angles, leaving the combined parts 22 at both ends.
A circular hole 24 through which the small diameter portion 74 of the pin 7 passes is bored in the portion. The vertical bed plate 31 is also an L-shaped bed plate in cross section as shown in FIG.
2 (in this embodiment, the bent top plate 33 is further bent downward at a right angle), and the bent piece 3
2 is provided with a long hole 34 having a short diameter into which the minimum diameter portion 73 of the pin 7 fits. In this way, the horizontal base plate 21 and the vertical base plate 31 are connected to the pin 7 as in the above embodiment.
It is attached and fixed by.

As described above, according to the assembly type pedestal according to the present invention,
The respective base plates (frame plates) can be individually stored and assembled into a frame at the installation site by simply pushing in the pins. Therefore, frames with the same length but different widths, frames with the same width but different lengths, frames with the same height but different widths, frames with the same width but different heights, etc. With the conventional welding type, it was necessary to prepare plates with different dimensions, but with the one of the present invention, base plates of various lengths, widths, and heights can be prepared. If they are aligned, there is an advantage that a frame of any size can be assembled and configured freely depending on the combination.
