Description

DETAILED DESCRIPTION OF THE INVENTION [Object of the Invention] (Industrial Field of Application) The present invention relates to an electrical appliance storage board (hereinafter abbreviated as the board) such as a switchboard or control board that stores electronic devices and the like.

(Prior Art) In the past, this type of panel was made into a box with an integral structure by connecting the section steel and the steel plate appropriately 1F1, and the equipment was placed inside the box.

Supplies such as circuit boards were attached, and then wiring and connections were made to form the board.

However, with this panel configuration, all of the box assembly is done by welding in the can making department, which requires a lot of time and effort to remove distortion after the box assembly. Also.

After can manufacturing, a large storage space will be provided in the panel assembly department. Furthermore, 1 assembly and wiring (hereinafter referred to as assembly and wiring)
Since the work was carried out in a narrow panel, there were drawbacks such as not only poor work efficiency but also difficulties in ensuring work safety.

In order to eliminate these drawbacks of panels, assembly-type panels with paneled frames have recently been used9.
This will be explained with reference to FIGS. 3 to 16.

FIG. 13 is an exploded perspective view of the conventional panel assembly type panel, and FIG. 14 is a front sectional view of the panel assembly type panel.

In these figures, the conventional panel assembly type board is shown.

Equipment frame 101. Instrument/unit mounting panels 102, 10
3°104, floor panel 106, side plate 107, door 108
The procedure for assembling a six-box body made up of ceiling panels 109 is as follows.

An equipment frame 101 is attached on the floor panel 106, an equipment frame support 105 is attached to the upper part of the equipment frame, and a side plate 107 and a ceiling panel 109 are attached next to form a box body. Furthermore, door 108
is rotatably attached to a side plate using a hinge or the like, and finally the instrument/unit mounting panels 102, 103, 104, on which devices such as instruments/units are attached, are attached to the equipment frame 101.

(Problems to be Solved by the Invention) However, in the conventional panel assembly type panel described above, since the main improvement is in the box structure, there is still one set of work inside the panel. In addition, the strength and rigidity of the frame is unexpectedly lower than that of a welded integral structure.6For example, the floor panel 10
6. Ceiling panel 109. The edges of the outer plate 107 are both bent into an L-shape or a U-shape to form a joint surface, so when the board is lifted, a vertical load is applied as shown in Figure 15. Therefore, deformation centering on the side plate 107 tends to occur, and when the board is in an installed state, the excitation force due to external forces such as other forces causes horizontal deformation as shown in Fig. 16, causing the board to deform as a center. There were problems such as not being able to obtain the required strength and rigidity.

Therefore, the present invention solves the problems with the conventional panel assembly type panels, provides sufficient strength and rigidity, and provides an electrical appliance storage panel that enables complete work outside the panel when assembling and arranging the panels. The purpose is to provide

[Structure of the Invention] (Means for Solving the Problems) The present invention provides for the installation of necessary electrical equipment outside the panel to the equipment frame where wiring is carried out, and to the lower and upper parts of this equipment frame, respectively, with screws.

The board of this embodiment is assembled.

Here, equipment such as a power supply unit, an electronic circuit board unit, and a meter are mounted and wired in the equipment frame 1, so that the electrical functions of the panel are concentrated in this one place. This makes it possible to carry out all the work for distributing one set safely and efficiently outside the panel in a comfortable working posture.

Figure 3 shows the above-mentioned equipment assembled into the equipment frame 1 during this off-panel work. It will be done. This equipment frame 1 is formed into a columnar frame by bending and welding plate materials, and in addition to its function as an equipment mounting frame, it also serves to connect the floor panel 2 and ceiling panel 3 and maintain strength as a panel structure. is in charge of Therefore, holes for bolting to the floor panel 2 are provided at the four corners of the bottom of the frame, and screw holes for fixing the ceiling panel 3 are provided at the four corners of the top.

As shown in FIG. 1, the floor panel 2 fixes the equipment frame 1 and is joined to the lower end of the side plate 4 to form the bottom of the panel. Therefore, the floor panel 2 is bent vertically with the steel plate facing upward in both width and depth directions, and the four corners are welded together to form a rectangular tray shape with a cable through hole 12 near the back side of the bottom. Also, near the front of the bottom, an equipment frame mounting pedestal 13 is welded to the side and bottom of the dish-shaped panel 2. The upper surface of this equipment frame mounting base 13 is provided with screw holes 14 for tightening one equipment frame 1 with bolts. Furthermore, side plate screw holes 15 are provided on both sides.
1. A plate mounting seat 16 is provided at the end of the front and rear surfaces.

FIG. 4 shows the equipment frame 1 with equipment mounted and wired set on the floor panel 2 described above.

The ceiling panel 3 is fixed to the upper part of the equipment frame 1 as shown in FIG. 1, and is combined with the upper end of the side plate 4 to form a ceiling part. Therefore, the ceiling panel 3 is folded back into a bag shape in both width and depth directions, and its four corners are welded together to form a rectangular tray shape with rigidity, and a ceiling top plate 6 is attached to each corner of the top surface. screw holes 17 for mounting, mounting holes 18 for the equipment frame 1, and screw holes 1 for side surfaces on both sides.
9 is provided.

FIG. 5 shows a state in which one of the ceiling panel 3 and side panel 4 is attached at the next stage of assembly shown in FIG. 4.

The side plate 4 is a single plate with the cross-sectional shape shown in Fig. 6, and by bending both ends into a bag shape and recessing the middle part one step, the side plate 4 has a large section modulus as a member, increasing the rigidity and improving sexual function. I'm leaning on it. moreover.

As will be described later, this recess has a shape that takes into account the attachment of equipment to the inside of the panel and the attachment of the side decorative plate 7 from the outside of the panel.

In this recessed part of the side plate 4, as shown in FIG. 1, there are holes 41 for connecting with the ceiling panel 3 and floor panel 2 at both the upper and lower ends, and side decorative plates 7 at the parts near the left and right diagonally bent parts. Hole 42 for attaching. The intermediate portion is provided with holes 43 for equipment and their mounting hardware. The dimensions of these hole devices are completely symmetrical both vertically and horizontally, so there is no need to distinguish between vertically and horizontally, and one board has only one type of side.
It is said to be compatible with 77iFi.

FIG. 7 shows the state of bolted connections of the parts that make up the panel box body, and shows the equipment frame l, floor panel 2, which has been described so far. Ceiling panel 3. FIG. 4 is a cross-sectional view showing the mutual relationship of side plates 4; Nuts are welded to the back side of the screw holes for both poles so that they can be attached to and detached from the outside of the panel from above.These joints are resistant to vertical loads such as hanging, and the steel plate portions do not bend. The structure is designed so that only a tensile load is applied to one bolt, and either a shear load or a tensile load is applied to one bolt. Therefore, it is possible to easily obtain the strength and rigidity of a box structure.

FIG. 8 is a perspective view of the multi-sided board 4 viewed from the inner surface of the board. Positioning notches 21 are provided only at the upper and lower ends of the end plate 20 folded into a bag shape. This notch 21 is formed in the floor panel 2. when assembling the panel. This is to enable easy positioning by fitting the ceiling panel 3.

FIG. 9 shows the side panel 4 and the floor panel 2. FIG. 3 is a perspective view showing a state in which the ceiling panel 3 is fitted into the position pipe fitting notch 21; In this case, floor panel 2. In both the ceiling panel 3 and the door, the contact surface 22 is moved back by the plate portion of the side panel 4, and a gap tends to occur between the gasket 1- and the contact surface 22 when the door is closed. To prevent this gap from occurring,
In order to connect the left and right side plates and maintain surface rigidity in the left and right direction, backing plates 8 are screwed to the top and bottom of both the front and rear sides, respectively.

For the above-mentioned reasons, the backing plate 8 has the same thickness as the side plate 4, and as shown in the lower part of FIG.

A joining hole 23 with the plate 4 is bored. A joining hole 24 with the floor panel 2 or ceiling panel 3 is bored in the horizontal part.

The closing rubber 25 is for dustproofing to close the gaps 26 at the four corners that occur when the side panel 4 and the floor panel 2) or the ceiling panel 3 are joined. For this purpose, it has a trapezoidal cross section that matches the bag shape of the multifaceted board 4, and its length is approximately the same as the thickness of the floor panel 2 and ceiling panel 3. The sealing rubber 25 is attached to the gap 26 by slightly compressing the rubber, inserting it from above, and setting it in place using a frictional force utilizing the elastic reaction force of the rubber.

FIG. 10 is a cross-sectional view showing a state in which an instrument is attached to the inner surface of the multi-face plate 4 and a side decorative plate 7 is attached to the outer surface. Here, devices that cannot be attached to the equipment frame 1 due to additions or modifications, such as the terminal block 27. An example is shown in which the switch 28 is mounted on the inner surface of the side plate 4 using a hole therein. This side surface decorative board 7 is covered with spacers 29 from the outside. It is detachably attached using decorative screws 30. The side decorative panel 7 is used to attach the tips of screws that protrude to the outside when a device is installed from the inside, as well as the floor panel 2 shown in FIG. Ceiling panel 3 and side panel 4
It plays the role of covering and hiding the heads of the bolts that are joined to maintain the appearance. Therefore, the thickness of the decorative side panel 7 may be approximately 1/3 of that of each panel constituting the main body, for example, the side panel 4, making it easier to handle due to its weight reduction. Further, from the viewpoint of maintaining the appearance described above, care is taken so that the surface of the side decorative plate 7 and both end surfaces of the side plate 4 are on the same plane when installed.

If it is known in advance that it is necessary to attach equipment to the side plate 4, the side plate 4 should be placed on a horizontal workbench outside the panel in the same way as when attaching equipment to the equipment frame 1. , and then the equipment can be attached.

The door 5 is attached to the pillar-shaped portion of the side plate 4 via a hinge, but the grooves do not particularly contribute to the strength development of the panel board, so a description thereof will be omitted.

The ceiling upper board 6 is placed on the assembled ceiling panel 3 of the box body, and its periphery is fixed to the ceiling panel with bolts.

Its role is to hide the bolt heads that connect the equipment frame 1 and the ceiling panel 3 and to keep out dust from inside the frame of the ceiling panel 3 for appearance purposes.

By configuring the board of this embodiment as described above, even if it is a panel assembly type, the strength and rigidity of the board can be obtained without using any special reinforcement. For example, the vertical load when the board is suspended is mainly borne by the equipment frame l and both side plates 4, and the load form is a simple tensile load. When the panel is hung by hanging wire ropes on hanging bolts set at the four corners of the ceiling panel 3, the top and bottom of the equipment frame 1 and the top and bottom of the side panels 4 are attached to the floor panels 2, respectively. Since it is connected to the ceiling panel 3 with bolts, the vertical load is distributed. Here, floor panel 2. 6I, where the side panel 4 is directly connected to the vertical side surface of the ceiling panel 3! ! The effect of construction is large.

Further, the board sideness in the left and right direction is obtained by the treading of one equipment frame 1 and the rigidity of the floor panel 2. That is, for its purpose, one device frame 1 has a short depth (front-to-back direction) and a long width (horizontal direction) of about 80% of the panel width. The floor panel 2 is integrally welded around the equipment frame mounting pedestal 13 and has sufficient rigidity. Therefore, sufficient rigidity can be obtained by joining the equipment frame I, the floor panel 2, the side plates 4 on both sides of the ceiling panel 32, and the four hitches 8.

Furthermore, the board sideness in the front-rear direction is obtained by joining the single-piece side plate 4 to the floor panel 2 and ceiling panel 3.

That is, the side plate 4 is a single plate with both ends bent into a columnar shape, and the middle plane part excluding the two ends is the floor panel 2. By joining and fastening the panel to the rigid side surface of the ceiling panel 3 in a two-layered manner, the effect of a rigid wall can be obtained despite the simple structure.

In this way, bending effects that are disadvantageous to temporary objects can be largely avoided, and the required strength and rigidity of the board box body can be easily obtained without using complicated joint shapes or structural reinforcing members.

Incidentally, although the above description has been about a single board, it goes without saying that the board of this embodiment can be used with two or more sides.

FIG. 11 is a cross-sectional view showing the connected state of the side plate portions in this row-of-boards configuration. Side plates 4A and 4B have holes for connecting bolts at predetermined positions on the joint surface for use in parallel panels.
This is an example in which panels are installed so as to face each other, and a connecting bolt 31 is passed through the connecting bolt hole described above and fastened using a washer and a nut. As can be seen from this figure, in the case of the side-by-side configuration, the decorative side panels 7 for the side panels 4A and 4B are not required. Further, even if the tips of the device attachment screws attached to the side plate protrude from each other, no problem will occur as long as they are within the range of the four parts of the side plate.

FIG. 12 is a cross-sectional view showing another embodiment of the side plate.

This is an example in which the cross-sectional center of the side panel 4C is protruded so as to be on the same plane as both ends, without basically changing the parts of the side panel that connect with the floor panel 2 and ceiling panel 3. This can accommodate an increase in the cross-section modulus of the side plate as well as an increase in the section modulus of the side plate.

Further, although not shown in the drawings, by removably mounting casters on the four corners of the lower surface of the floor panel 2, it becomes possible to easily transport the product on the floor between processes or at the installation site.

[Effects of the Invention] As explained above, according to the present invention, in the assembly process, necessary panels can be supplied in the order of the work process, and one assembly process or complete out-of-board work can be carried out, so assembly work can be simplified. It becomes possible to hire In addition, the main panels have a simple joint shape to reduce the load on the structural members without sacrificing strength or rigidity, so in the final process of 1 assembly, the panels can be joined and assembled into a box shape in order to create reinforcements. A predetermined board sideness can be obtained without using any of the above.
