(How to install the base frame)
Returning to FIG. 8, a method for installing the base frame 80 will be described next.

This installation method is a method for installing the base frame 80 on the frame 2, and in the embodiment includes a temporary fixing step, a main fixing step, and a water intrusion prevention step. Note that this installation method will be explained on the assumption that the indoor switchgear 1 is already installed in the opening 3.

(How to install the base frame - temporary fixing process)
First, the temporary fixing step will be explained. The temporary fixing process is a process for temporarily fixing the base frame 80 to the frame 2.

Specifically, first, at the site (or factory, etc.) where the outdoor switchgear 10 is installed, using a known method, the upper base member 81, the lower base member 82, and the intermediate base member 83 (inner corner side The base frame 80 is assembled by combining the intermediate base member 83) having the temporary fixing notch 111 and the non-entered corner side temporary fixing notch 112, the inside corner base member 84, and the non-entered corner base member 85. . (Note that if the base frame 80 has already been assembled, this work can be omitted).

Next, the inside corner side temporary fixing locking part 101 and the non-inside corner side temporary fixing locking part 102 are attached to the frame 2 (specifically, the beam part 2a located near the upper end of the opening 3). Attach them to the desired parts of the above.

Next, as shown in FIG. 8, the inside corner side temporary fixing notch 111 of the intermediate base member 83 is locked to the inside corner side temporary fixing locking part 101, and the non-inside corner side temporary fixing part of the intermediate base member 83 is locked. The base frame 80 is temporarily fixed to the frame 2 by locking the fixing notch 112 to the non-entered corner side temporary fixing locking part 102. In this case, for example, the position of the base frame 80 in the left-right direction can be easily adjusted by sliding the base frame 80 along the left-right direction while maintaining the base frame 80 temporarily fixed to the frame 2. It becomes possible to do so.

With such a temporary fixing step, the base frame 80 can be permanently fixed more accurately and easily, and the ease of installation of the base frame 80 can be improved, compared to the case where the temporary fixing step is omitted.

(How to install the base frame - main fixing process)
Next, the main fixing step will be explained. The main fixing step is a step for permanently fixing the base frame 80 to the frame 2 after the temporary fixing step.

Specifically, as shown in FIG. 9, the inside corner base member 84 is fixed to the fixing target portion 4 using a plurality of main fixing fixtures 200 and connecting parts 210. More specifically, a plurality of main fixing fixtures 200 are inserted into the main fixing mounting holes 201 formed in the inner corner base member 84 and the connecting part 210 from the outside side of the building rather than the opening 3. It is fixed by attaching it to the fixing target part 4 respectively.

Further, the upper base member 81, the lower base member 82, the intermediate base member 83, and the non-entered corner base member 85 are each fixed to the fixing target portion 4 using a plurality of main fixing fixtures 200. More specifically, from the outdoor side of the building rather than the opening 3, a plurality of main fixing fixtures 200 are attached to the upper base member 81 (or the lower base member 82, the intermediate base member 83, or the non-entered corner base member). They are fixed by inserting them into the main fixing attachment holes 201 formed in the member 85) and attaching them to the fixing target parts 4, respectively.

Here, the order in which the various base members are fixed is arbitrary, but for example, from the base member located on the lower side to the base member located on the upper side (specifically, the lower base member 82, the inner corner It may be fixed to the side base member 84, the non-entered corner side base member 85, the intermediate base member 83, and the upper base member 81), or it may be fixed in the reverse order. Alternatively, the order is from the base member located on the inside corner side to the base member located on the non-entered corner side (specifically, the inside corner side base member 84, the lower base member 82, the intermediate base member 83, the upper base member 81 , the non-entered corner side base member 85), or may be fixed in the reverse order. Alternatively, after fixing only a portion of each base member, the other portions of each base member may be respectively fixed.

Through this main fixing process, the main fixing fixture 200 for fixing various base members to the fixing target part 4 can be attached from the expected direction, and the base member is fixed to the frame 2 on the side of the target part 4. The work of attaching the main fixing fixture 200 can be performed more efficiently than in the case where the main fixing fixture 200 is installed.

(Installation method of base frame - water intrusion prevention process)
Next, the flood prevention process will be explained. The water intrusion prevention step is a step for preventing water from entering through the gap between the base frame 80 and the frame 2 after the main fixing step or during the temporary fixing step (or main fixing step).

Specifically, as shown in FIG. 8, during the temporary fixing process (for example, at the timing of assembling the base frame 80), the non-entered corner upper cover part 300, the non-entered corner lower cover part 301, the inner corner upper part Attach the cover part 302, the inner corner lower cover part 303, and the inner corner side water stop member 323 (however, this is not limited to this; for example, they may be attached after the temporary fixing step or after the main fixing step ).

In addition, as shown in FIG. 12, after the main fixing step (for example, immediately after the main fixing step or immediately after the installation of the outdoor switchgear 10), the water stop gap on the cover side is fixed using a known method. 330, the third cover side water stop member 322, the non-enter corner side water stop member 324, and the upper water stop member in the non-entering corner water stop gap 331, the upper water stop gap 332, and the enter corner gap 334. Provided by filling 325. This completes the installation of the base frame 80.

Through such a water intrusion prevention step, it is possible to suppress water from entering through the gap between the base frame 80 and the frame 2, and it is possible to improve the water-stopping properties of the base frame 80.

(effect)

Further, the temporary fixing locking part 100 can be constructed relatively easily and inexpensively, and the installation cost of the temporary fixing structure can be suppressed.

In addition, since the temporary fixing locking part 100 is configured so that the temporary fixing locking part 100 can be inserted into the temporary fixing notch 110, the temporary fixing locking part 100 can be inserted into the temporary fixing notch 110. Compared to the case of locking without being inserted into the portion 110, the temporary fixing locking portion 100 can be prevented from falling off from the temporary fixing notch 110, and the base member can be temporarily fixed stably.

In addition, the length of the base member in the temporary fixing notch 110 in either the longitudinal direction or the lateral direction of the base member is determined by Since the length is longer than the length along the other side, when temporarily fixing the base member, the position of either the longitudinal direction or the width direction of the base member can be adjusted, and the base member can be adjusted according to the situation. It becomes possible to perform temporary fixation.

In addition, the edge portion of the temporary fixing notch 110 on the side where the temporary fixing locking portion 100 is locked is aligned approximately along either the longitudinal direction or the lateral direction of the base member. Since it is formed in a straight line, the position of the base member in the longitudinal direction can be accurately adjusted, and the usability of the temporary fixing structure can be easily improved.

In addition, temporary fixing notches 110 are provided at each end of the base member in the longitudinal direction or in the vicinity thereof, and the temporary fixing locking portions 100 are locked to the temporary fixing notches 110 in the frame 2. Since they are attached to each possible part, the base member can be provided approximately along the longitudinal direction of the base member, compared to the case where a plurality of temporary fixing notches 110 are provided near the longitudinal center of the base member. It becomes possible to perform temporary fixation accurately. In particular, even if the positions of the plurality of temporary fixing notches 110 are shifted from their original positions due to manufacturing errors etc., compared to the case where a plurality of temporary fixing notches 110 are provided near the longitudinal center of the base member, Therefore, the influence of the deviation can be reduced. Also, for example, it becomes easier to attach a plurality of fixing tools 200 for main fixing, which will be described later, at regular intervals on the inner side of the temporary fixing notch 110 in the base member, making it easier to maintain the mountability of the fixing tools 200 for main fixing. .

Moreover, since the temporary fixing locking part 100 is attached to the beam part 2a or the column part 2b of the frame 2, the temporary fixing locking part 100 can be firmly attached to the frame 2, and the temporary fixing part 100 can be firmly attached to the frame 2. The ease of attaching the locking part 100 can be improved.

Moreover, since the temporary fixing locking part 100 is a screw with a head or a screw with a head, it can be easily attached by piercing or screwing the temporary fixing locking part 100 itself into the frame 2. The base member can be prevented from falling off from the temporary fixing locking part 100 by the screw or the head of the screw, and the installation work of the temporary fixing locking part 100 can be performed efficiently. Moreover, the temporary fixing locking part 100 can be constructed at low cost, and the manufacturability of the temporary fixing locking part 100 can be improved.

In addition, since the base member is formed into a hollow body and the temporary fixing notch 110 is arranged at the part of the base member that comes into contact with the frame 2, the temporary fixing notch 110 is placed outside the contact part of the base member. The temporary fixing locking part 100 can be stably locked in the temporary fixing notch 110, and the base member can be stably temporarily fixed, compared to the case where the temporary fixing locking part 100 is disposed in the temporary fixing notch part 110.

(Effect of appendix)
According to the temporary fixing structure of the base member described in Appendix 1, the temporary fixing locking means that can be attached to the frame without using a fixing tool, and the temporary fixing notch provided in the base member, Since it includes a temporary fixing notch that can be locked by the fixing locking means, the base member can be temporarily fixed, and the base member can be permanently fixed accurately and easily. Furthermore, the temporary fixing locking means can be configured relatively simply and inexpensively, and the installation cost of the temporary fixing structure can be suppressed.

According to the temporary fixing structure of the base member described in Appendix 2, the temporary fixing locking means is configured so that the temporary fixing locking means can be inserted into the temporary fixing notch, so that the temporary fixing is not possible. Compared to the case where the locking means is locked without being inserted into the temporary fixing notch, the temporary fixing locking means can be prevented from falling off from the temporary fixing notch, and the base member can be stabilized. It can be temporarily fixed.

According to the temporary fixing structure of the base member described in Appendix 3, the length of the base member in the temporary fixing notch along either the longitudinal direction or the lateral direction of the base member in the temporary fixing notch is Since the length of the member is longer than the length along either the longitudinal or lateral direction of the member, when temporarily fixing the base member, it is necessary to adjust the position of either the longitudinal or lateral direction of the base member. This makes it possible to temporarily fix the base member depending on the situation.

According to the base member temporary fixing structure described in Appendix 4, the edge of the temporary fixing notch on the side where the temporary fixing locking means is locked is aligned in the longitudinal direction of the base member or Since it is formed in a straight line substantially along either one of the transverse directions, the position of the base member in the longitudinal direction can be accurately adjusted, and the usability of the temporary fixing structure can be easily improved.

According to the temporary fixing structure of the base member described in Appendix 5, the temporary fixing notch is provided at each end of the base member in the longitudinal direction or in the vicinity thereof, and the temporary fixing locking means is provided in the temporary fixing structure of the base member. Since they are each attached to a part that can be locked to the fixing notch, compared to the case where multiple temporary fixing notches are provided near the longitudinal center of the base member, the base member can be attached approximately along the longitudinal direction of the base member. Therefore, it is possible to accurately temporarily fix the base member. In particular, even if the positions of the plurality of temporary fixing notches are shifted from their original positions due to manufacturing errors, compared to the case where multiple temporary fixing notches are provided near the longitudinal center of the base member, The influence of that deviation can be reduced. Further, for example, it becomes easier to attach a plurality of fixing tools for permanent fixing at regular intervals in a portion inside the temporary fixing notch in the base member, so it becomes easier to maintain the attachability of the fixing tools for main fixing.

According to the temporary fixing structure of the base member described in Appendix 6, since the temporary fixing locking means is attached to the beam or column part of the structure, the temporary fixing locking means can be firmly attached to the structure. The temporary fixing locking means can be easily attached.

According to the temporary fixing structure of the base member described in Appendix 7, the temporary fixing locking means is a screw with a head or a screw with a head, so the temporary fixing locking means itself cannot be pierced or screwed into the frame. This allows for easy installation, and also prevents the base member from falling off the temporary fixing locking means due to the head of the screw or screw, making it possible to efficiently perform the installation work of the temporary fixing locking means. . Further, the temporary fixing locking means can be constructed at low cost, and the manufacturability of the temporary fixing locking means can be improved.

According to the temporary fixing structure of the base member described in Appendix 8, the base member is formed into a hollow shape, and the temporary fixing notch is arranged in the part of the base member that comes into contact with the frame. Compared to the case where the notch is placed in a part of the base member other than the abutting part, the temporary fixing locking means can be stably locked in the temporary fixation notch, making it easier to stably temporarily fix the base member.
