When the cut groove on the edge of the reinforcing material is fitted into the cut groove on the corresponding support plate, the end of the bottom plate of the reinforcing material is applied to one surface of the support plate, and the reinforcing material is moved in the thickness direction of the bottom plate. Swinging and tilting in the vertical direction are restricted, and in addition to this, the concave portion and the protrusion are fitted to restrict the movement of the reinforcing material in the length direction (left and right direction). The insertion hole and the screw hole are positioned and supported in alignment.
In other words, the reinforcing material is positioned in a state where the insertion hole and the screw hole are aligned with each other and can be temporarily fixed to the support plate. Therefore, when the screwing operation is performed, for example, the end of the reinforcing material is lifted and positioned. There is no need for screwing, and the screwing operation can be performed in a state where both hands are free following the temporary fixing. As a result, the screwing work can be efficiently performed in a short time, and the attaching work of the reinforcing material can be easily performed.

For example, the projection and the recess can be reliably fitted to ensure accurate positioning.

<Embodiment>
Hereinafter, an embodiment of the present invention will be described with reference to FIGS.
First, the overall structure will be described with reference to FIGS. The storage main body 10 (hereinafter referred to as the main body 10) is formed by a vertically long heat insulating box whose front surface is opened, and is supported by legs 11 arranged on the bottom surface. The interior of the main body 10 is a storage chamber 12, and a horizontal partition frame 14 is mounted at the center height position of the front opening, thereby forming upper and lower two-stage entrances 15. A door 15A is attached. A machine room 16 is provided on the upper surface of the main body 10.

This machine room 16 has columns 17 and 18 erected at the four corners of the upper surface of the main body 10, a front panel 20 having an air inlet 19 formed in the center on the front side, and side panels 21 on both sides. Each is stretched, and the top and back surfaces are open. As will be described in detail later, a reinforcing member 60 made of a channel is passed and fixed between the adjacent support columns 18 on the back side.
A square opening 23 is formed at the bottom of the machine room 16, in other words, on the back side of the ceiling wall of the main body 10, and on the lower surface side of the opening 23 in the ceiling of the storage room 12. The air duct 24, which also serves as a drain pan, is stretched in a slanting posture in a downward direction, and a cooler chamber 25 is formed.

On the other hand, a heat-insulating mounting base 26 that is slightly larger than the above-described opening 23 is provided. On the upper surface of the mounting base 26, a compressor 28 constituting a refrigeration apparatus 27 and a condenser with a condenser fan 29A are provided. 29 are placed side by side sequentially from the rear, and a cooler 31 (evaporator) is attached to the lower surface, and the cooler 31 and the refrigeration apparatus 27 are connected by circulation through a refrigerant pipe to form a unit. A well-known refrigeration cycle is configured.
The mounting base 26 of the above unit closes the opening 23 and is placed, whereby the refrigeration apparatus 27 is accommodated in the machine room 16, and the cooler 31 is housed in the cooler room 25. 32 can be accommodated.

During operation, when the internal fan 32 is driven together with the refrigeration apparatus 27, the internal space drawn by the internal fan 32 through the suction port 33 provided at the front position of the air duct 24 as shown by the arrow in FIG. Air passes through the cooler 31 to generate cool air, and the cool air is blown out from the air outlet 34 provided at the rear position of the air duct 24 and circulated into the storage chamber 12. During this time, the internal temperature is detected by an internal sensor (not shown), and the operation and stop of the refrigeration apparatus 27 and the internal fan 32 are controlled according to the internal temperature, so that the internal temperature is maintained at a substantially constant cooling temperature. It has come to be.
In addition, during the cooling operation, as indicated by the arrow in FIG. 2, the outside air is sucked from the intake port 19 of the front panel 20 and passes through the condenser 29 as the condenser fan 29A is driven. The cooled and heat-exchanged warm air is discharged to the outside through the opening on the back surface of the machine room 16 and the opening on the rear side of the upper surface.

The above-described machine room 16, particularly the frame structure thereof will be described in more detail.
The pair of left and right support columns 17 arranged on the front side are formed by bending a second support plate 41 having a narrow width from the vertical edge of the L-shaped first support plate 40 and forming a line symmetrical shape on the left and right. A lower plate 42 having a plane L shape is formed by bending the inner plate at right angles from the lower edges of the support plates 40 and 41. The left and right support columns 17 are placed at the left and right corners on the front side of the upper surface of the main body 10 in a posture in which the respective second support plates 41 face each other, and are fixed by screwing the lower plate 42. Yes. The above-described front panel 20 is detachably attached across the second support plates 41 of the both columns 17. In addition, a through-hole 43 into which a hand can be inserted is formed on the lower side of the first support plate 40 in both struts 17 so that the strut 17 can be used as a handle during transportation.

As shown in detail in FIG. 3 and FIG. 4, the pair of left and right support columns 18 arranged on the back side is substantially half the width of the first support plate 45 from one vertical edge of the wide first support plate 45. The second support plate 46 is formed by bending at right angles, and has a symmetrical shape on the left and right. The second support plate 46 of the column 18 corresponds to the support plate of the present invention.
A flange bent at a right angle is formed on the other vertical edge of the first support plate 45, and an upper plate 47 and a lower surface of the plane L-shape are respectively formed from the upper and lower edges of the support plates 45 and 46, respectively. The plate 48 is formed by bending at a right angle inward. A plurality of mounting holes are opened in the lower plate 48, and the left and right columns 18 are mounted on the left and right corners on the back side of the upper surface of the main body 10 with the respective second support plates 46 facing each other. It is fixed by fixing with a screw 50 using the mounting hole of the lower plate 48. However, the mounting holes of the short sides facing the left-right direction in the lower plate 48 are long holes 49 extending in the same direction.
In addition, the through holes 43 into which the hands are respectively inserted are formed at the two upper and lower positions of the first support plate 45 in both struts 18 so that the struts 18 can be used as handles when transporting.

Now, between the upper ends of the second support plates 46 of the above-mentioned back-side support columns 18, the reinforcing material 60 is passed and fixed. The reinforcing member 60 is formed of a channel material formed by bending side plates 62 at right angles on both side edges of the elongated bottom plate 61.
The reinforcing member 60 has a total length that is larger by a predetermined amount than the opening between the opposing vertical edges 46A of the second support plates 46 of both struts 18. In particular, the end edge of the bottom plate 61 is the end edge of the side plate 62. Further, it is formed to extend in the length direction (extension portion 63).

  A cut groove 65 into which the vertical edge 46A of the second support plate 46 of the corresponding column 18 can be inserted is formed at the base portion at both end edges in the length direction of the upper and lower side plates 62. Each cut groove 65 has a depth that is slightly larger than the length of the extending portion 63 of the bottom plate 61 described above. Further, in the almost half depth region on the inlet side (opening side) of the cut groove 65, one side edge is formed obliquely so that the groove width gradually increases toward the inlet side. On the inlet side, an introductory taper 65A is formed.

On the other hand, two upper and lower cut grooves 51 are formed at the upper end portions of the vertical edges 46A facing each other in the second support plate 46 of both struts 18. The end edges of the upper and lower side plates 62 of the reinforcing member 60 can be inserted into the both cut grooves 51, and the upper cut groove 51 is formed at the upper edge of the vertical edge 46 </ b> A of the second support plate 46. The lower cut groove 51 is formed at a lower position spaced from the upper cut groove 51 by the same distance as the distance between the side plates 62. Further, the cut groove 51 has substantially the same depth as the straight portion 65B on the back side in the cut groove 65 on the reinforcing material 60 side.
In other words, the cut groove 51 on the second support plate 46 side and the straight portion 65B of the cut groove 65 on the reinforcing material 60 side can be fitted to each other, and both the cut grooves 51 and 65 are fitted. In this case, as shown in FIG. 8, the predetermined end region (contact region 64) including the extending portion 63 in the bottom plate 61 of the reinforcing member 60 is a half on the vertical edge 46 </ b> A side on the surface of the second support plate 46. It contacts (overlaps) the weak width region.

An insertion hole 68 of a screw 67 is opened at the base side of the contact region 64 in the bottom plate 61 of the reinforcing member 60 and at the center in the width direction (vertical direction). On the other hand, a screw hole 53 into which the above-described screw 67 is screwed is cut at a corresponding position near the vertical edge 46 </ b> A in the second support plate 46 of the column 18.
A protrusion 69 having a triangular pyramid shape is formed by being knocked out toward the back surface (contact surface) side at a position closer to the front end side of the predetermined dimension from the insertion hole 68 in the bottom plate 61 described above. As shown in FIG. 6, the protrusion 69 is formed with a posture in which the bottom edge is directed vertically, and the bottom edge is a locking edge 69 </ b> A. On the other hand, a square hole 54 into which the above-described protrusion 69 can be fitted is opened at a position having the same dimension from the screw hole 53 in the second support plate 46 to the back.

When the protrusion 69 fits into the square hole 54, the movement of the reinforcing member 60 in the left-right direction, mainly the movement away from the second support plate 46, is restricted. At this time, as shown in FIG. And the screw hole 53 are aligned.
A window hole 56 is opened from the upper plate 47 of the support column 18 to the upper end of the second support plate 46 so as to correspond to the position above the formation position of the square hole 54, and a jig or the like is inserted. Thus, it can be used to release the fitting between the projection 69 and the square hole 54.
Further, at the end of the bottom plate 61 of the reinforcing member 60, reinforcing ribs 71 having a horizontal posture are formed by being struck out to the surface side at two positions above and below the insertion hole 68. Both the reinforcing ribs 71 have dimensions slightly longer than the length of the contact area 64 in the bottom plate 61 and are formed to extend inward from the position between the insertion hole 68 and the protrusion 69.

Then, the effect | action of this embodiment is demonstrated.
When assembling the machine room 16, first, in order to form a frame body, the columns 17 and 18 are erected in predetermined postures at the four corners of the upper surface of the main body 10 and fixed by screwing, and then the two on the rear side are fixed. A reinforcing member 60 is passed over and fixed to the column 18.
An example of the attachment procedure of the reinforcing member 60 is as follows. First, as shown in FIG. 3, the two support columns 18 on the back side are in a posture in which the second support plates 46 face each other, and are fixed by tightening the screws 50 through the mounting holes of the lower plate 48. At that time, for example, with respect to the right support column 18 as viewed from the back, the screw 50 is temporarily fixed, and the second support plate 46 is moved to the outside as shown by the arrow X in FIG. Keep the posture shaken.

  As shown in FIGS. 3 and 4, the reinforcing member 60 is held in a substantially horizontal posture with the bottom plate 61 facing the front side (rear side), and is first extended on one end side (left end side viewed from the rear side) of the bottom plate 61. The protruding portion 63 is applied to the upper side of the surface of the second support plate 46 of the corresponding column 18, and then the reinforcing member 60 is moved upward until the upper side plate 62 hits the upper plate 47. At this time, since the reinforcing grooves 60 and the cut grooves 65 and 51 of the second support plate 46 correspond to each other, the left end portion of the bottom plate 61 is continuously moved to the left while sliding on the surface of the second support plate 46. Then, the cut groove 65 of the reinforcing member 60 is fitted into the cut groove 51 of the corresponding second support plate 46. Here, since the introduction portion 65A having a tapered shape is formed on the inlet side of the cut groove 65 of the reinforcing member 60, the cut portion of the second support plate 46 is guided by the introduction portion 65A. 51 is smoothly fitted to the straight portion 65 </ b> B of the cut groove 65 of the reinforcing member 60.

  When the cut groove 51 of the second support plate 46 is fitted into the straight portion 65B of the cut groove 65 of the reinforcing member 60, the reinforcing member 60 swings in the plate thickness direction (front-rear direction) of the bottom plate 61, and When tilted in the vertical direction is restricted and is pushed in until the rear ends of both the cut grooves 65 and 51 come into contact with each other, as shown in FIGS. 7 and 8, it protrudes from the back side of the end portion of the bottom plate 61. The projection 69 thus fitted fits into the square hole 54 of the second support plate 46, and the movement of the reinforcing member 60 in the left-right direction is restricted. At this time, the insertion hole 68 of the screw 67 provided in the bottom plate 61 and the screw hole 53 provided in the second support plate 46 are aligned.

On the other end side (right end side) of the reinforcing member 60, as described above, the right column 18 is swung outward, so the reinforcing member 60 has a slight gap between the cut grooves 65 and 51. The right end side is tilted slightly to the front (back side) using the clearance, and the extended end of the bottom plate 61 is placed on the vertical edge of the second support plate 46 swinged diagonally in the right column 18. It is in a hit state. From this state, when the right end side of the reinforcing member 60 is pushed forward so as to be in a straight posture, the support column 18 rotates so that the second support plate 46 takes a straight posture in which the left and right directions are directed, while the bottom plate 61 The right end moves to the right along the surface of the second support plate 46, and similarly, the cut groove 65 of the reinforcing member 60 fits into the cut groove 51 of the corresponding second support plate 46. Similarly, an introduction portion 65A having a tapered shape is formed on the inlet side of the cut groove 65 of the reinforcing member 60, so that the introduction is made despite the fact that the second support plate 46 is initially inclined. The cut groove 51 of the second support plate 46 is smoothly fitted to the straight portion 65B of the cut groove 65 of the reinforcing member 60 by being guided by the portion 65A.
Further, when the rear ends of both the cut grooves 65 and 51 are pushed into contact with each other, the protrusion 69 of the bottom plate 61 fits into the square hole 54 of the second support plate 46, and the lateral movement of the reinforcing member 60 is performed. In this state, the insertion hole 68 of the bottom plate 61 and the screw hole 53 of the second support plate 46 are aligned. Then, the screw 50 of the right column 18 is finally tightened and fixed.

  In the state where the operations up to this point are completed, the pillars 18 are erected and fixed at the two corners on the back side of the upper surface of the main body 10, while the reinforcing member 60 has the cut grooves 65, 51 is fitted to each other, the abutment region 64 of the bottom plate 61 of the reinforcing member 60 is applied to the surface of the second support plate 46, and the reinforcing member 60 swings in the front-rear direction and in the vertical direction. Inclination is restricted, and in addition, the protrusion 69 and the square hole 54 are fitted to each other, so that the movement of the reinforcing member 60 in the left-right direction is also restricted. The insertion hole 68 and the screw hole 53 are positioned and temporarily fixed in alignment.

In this state, since the reinforcing member 60 does not fall from the support column 18 and the insertion hole 68 and the screw hole 53 are aligned even if the operator does not put his hand on, one side is successively applied. The screw hole 67 may be screwed into the screw hole 53 and fixed to the insertion hole 68.
When the frame body is assembled in this way, the machine room 16 is formed by stretching the side panel 21 and the front panel 20.

  As described above, according to the present embodiment, in the structure of the portion where the reinforcing member 60 is fixed between the supporting columns 18 on the back side, both ends of the reinforcing member 60 are attached to the second support plates 46 of the corresponding supporting columns 18. On the other hand, since the insertion hole 68 and the screw hole 53 are positioned and temporarily fixed so that they can be temporarily fixed, when screwing, for example, the end of the reinforcing member 60 is lifted and positioned while screwing. There is no need to stop, and the screwing operation can be performed in a state where both hands are free following the temporary fixing. As a result, the screwing operation can be efficiently performed in a short time, and the attaching operation of the reinforcing member 60 can be easily performed.

  In the end portion structure of the reinforcing member 60, the end edge of the bottom plate 61 extends from the end edge of the side plate 62, so that the end portion of the reinforcing member 60 corresponds to the second support plate 46 of the corresponding column 18. When assembling, the extended portion 63 of the bottom plate 61 is first applied to the surface of the second support plate 46, and then the extended portion 63 is shifted up and down to align the cut grooves 65 and 51 with each other. Thus, the end portion of the reinforcing member 60 is moved in the horizontal direction to the corresponding second support plate 46 side, and an operation of fitting both the cut grooves 65 and 51 to each other can be performed. Therefore, it is possible to more easily perform the fitting operation between the two cut grooves 65 and 51.

In addition, since an introduction portion 65A in which the groove width gradually increases toward the inlet is formed on the inlet side of the cut groove 65 on the reinforcing material 60 side, when the both cut grooves 65 and 51 are fitted, 2 The vertical edge 46A of the support plate 46 is guided by the tapered introduction portion 65A, and the cut grooves 65 and 51 are smoothly fitted to each other. The fitting operation between both the cut grooves 65 and 51 is further simplified.
Further, when the end portion of the bottom plate 61 of the reinforcing member 60 is viewed, a notch groove 65 is formed between the side plate 62 and the edge of the bottom plate 61 extends. In other words, it can be said that there is a risk of deformation from the position of the cut groove 65. In this respect, in this embodiment, since the reinforcing rib 71 is formed by knocking out at the end portion of the bottom plate 61, the end portion of the bottom plate 61 can be prevented from being deformed. Therefore, the protrusion 69 and the square hole 54 are securely fitted, and accurate positioning can be expected.
