[Problems to be solved by the invention]
By the way, in the fixing base 3 of the elevator control panel 1 configured as described above, as shown in FIG. 5, the width W between the anchor bolts 5, 5 for fixing the elevator control panel 1 in the fore-edge direction is increased. Due to the small height, the height H from the center of gravity G of the elevator control panel 1 to the surface of the floor concrete 3 is high, and there is a problem that it is difficult to secure sufficient fall prevention strength. .
[0017]
Therefore, it is conceivable to increase the fixing strength of the wire 9 or the stay 16. However, in order to fix the wire 9 or the stay 16, the versatility such as the installation position of the elevator control panel 1 is restricted. In addition to this, there has been a problem that the balance with the building construction side (meeting, etc.) is troublesome.
[0018]
Furthermore, the work of fixing the wiring duct 10 for arranging the fixing stand 2 and the wiring 20 to the floor concrete 3 separately from the fixing stand 2 also needs to consider the arrangement relationship with the fixing stand 2. Along with this, there has also been a problem that it is very troublesome.
[0019]
The present invention provides a fixing frame for an elevator control panel that can secure the fixing strength without using a dedicated fixing member for fixing the upper surface of the elevator control panel, in order to solve the above problem. The purpose is to:
[0020]
It is another object of the present invention to provide an elevator control panel fixing stand that can eliminate the need for a wiring duct and can reduce the number of parts and the number of steps in the entire elevator installation work.
[0021]
[Means for Solving the Problems]
In order to achieve the object, the fixing base of the elevator control panel according to the present invention includes a fixing portion for fixing a bottom surface of the housing-like elevator control panel, and a protruding portion protruding laterally from the fixing portion, A fixing member penetrating hole penetrating through the one end of the fixing part and the other end of the protruding part located on the opposite side to the one end is provided.
[0022]
In such a configuration, the bottom surface of the housing-like elevator control panel is fixed to the fixed portion, and the protruding portion protrudes laterally beyond the fixed portion, and is located at one end of the fixed portion and on the opposite side to the one end. The fixing member penetrates the through hole formed near the other end of the located protrusion.
[0023]
Further, the fixing stand of the elevator control panel according to the present invention is characterized in that the protruding portion is a wiring duct arranged from the elevator control panel.
[0024]
BEST MODE FOR CARRYING OUT THE INVENTION
Next, an embodiment of a fixing base for an elevator control panel according to the present invention will be described with reference to the drawings.
[0025]
1 and 2 show a mounting base for fixing an elevator control panel according to the present invention. FIG. 1 (A) is a front view showing a state where the elevator control panel is fixed to the mounting base, and FIG. 1 (B) is an elevator control panel. FIG. 1C is a perspective view of the fixing base, and FIG. 2 is an enlarged cross-sectional view of a main part of the fixing base.
[0026]
In FIG. 2, reference numeral 21 denotes a housing-like elevator control panel, 22 denotes a fixing stand to which the elevator control panel 21 is fixed via bolts or the like (not shown), 24 denotes floor concrete, and 23 denotes floor concrete 24. Reference numeral 25 denotes an anchor bolt for fixing the elevator control panel 21 integrally with the fixing stand 22 to the floor concrete 24.
[0027]
As shown in FIG. 1C, the fixing base 22 includes a pair of base frames 26 facing each other and having an L-shaped cross section, and four support frames raised from one end of the base frame 26 and the center. 27, a fixed frame 28 having a rectangular frame shape fixed to the upper end of the support frame 27, a reinforcing frame 29 provided between one end of the base frame 26, and a wiring holder 30 provided between the other ends of the base frame 26. And a reinforcing side panel 31 provided between the support frames 27 near the center.
[0028]
The base frame 26 is formed with a fixing long hole 26a through which the anchor bolt 25 penetrates near both ends thereof, so that the width of the elevator control panel 21 in the fore-edge direction when the elevator control panel 21 is fixed to the fixed frame 28. The elevator control panel 21 can be fixed at an interval w wider than (corresponding to the depth). A portion extending from the center of the base frame 26 to the wiring holder 30 fixed to the other end is a routing duct portion 32 which also serves as a routing space for the wiring 20. As a result, the wiring holder 30 has a wiring through hole 30a for routing.
[0029]
The fixed frame 28 has a bolt insertion hole 28 a for fixing the elevator control panel 21 with bolts, and a drill through hole 28 b for forming a fixing long hole 26 a near one end of the base frame 26.
[0030]
The anchor bolts 25 correspond to a total of four places at both ends in the longitudinal direction of the elevator control panel 21 as shown in FIG. 1A and at both ends in the fore-edge direction of the elevator control panel 21 as shown in FIG. Is located in the position.
[0031]
In such a configuration, the lower part of the elevator control panel 21 is fixed to the floor concrete 24 by the anchor bolts 25 via the fixing gantry 22.
[0032]
At this time, the fore-edge direction of the elevator control panel 21 is fixed to the fixing base 22 by the anchor bolts 25 spaced apart by a width w wider than its depth. Even if the height H up to the surface of the 24 is high, it is possible to secure a strong fixing strength that prevents the elevator control panel 21 from overturning.
[0033]
In addition, since the fixing base 22 secures a wide interval w in the fore-edge direction of the anchor bolt 25 and integrally forms the routing duct portion 32 of the wiring 20, a dedicated duct (for example, a distribution duct) is provided. It is possible to eliminate the need to install the countermeasure duct 10) separately from the fixing base 22.
[0034]
【The invention's effect】
In the fixing base of the elevator control panel according to the present invention, the fixing strength is ensured while eliminating the need for a dedicated fixing member for fixing the upper surface of the elevator control panel by employing the above-described configuration. can do.
[0035]
In addition, a wiring duct may not be required, so that the number of parts and the number of man-hours for the entire elevator installation work can be reduced.
