[0016]
[Problems to be solved by the invention]
By the way, in the fixing stand 3 for the elevator control panel 1 configured as described above, as shown in FIG. 5, there is a W between the anchor bolts 5 and 5 for fixing the direction of the small edge of the elevator control panel 1. Due to the narrowness, there is a problem that it is difficult to ensure sufficient fall prevention strength in combination with the high height H from the center of gravity G of the elevator control panel 1 to the surface of the floor concrete 3. .
[0017]
Therefore, it is conceivable to increase the fixing strength of the wire 9 and the stay 16, but in the first place, in order to fix the wire 9 and the stay 16, there is versatility such as restrictions on the installation position of the elevator control panel 1. In addition to being low, there was a problem that the trade-off with the building construction side (meeting etc.) was troublesome.
[0018]
Further, the work of fixing the wiring duct 10 for arranging the fixing base 2 and the wiring 20 to the floor concrete 3 separately from the fixing base 2 needs to consider the arrangement relationship with the fixing base 2. In combination with this, there was a problem that it was very troublesome.
[0019]
In order to solve the above problems, the present invention provides an elevator control panel fixing stand that can secure fixing strength while eliminating the need for a dedicated fixing member for fixing the upper surface of the elevator control panel. For the purpose.
[0020]
It is another object of the present invention to provide an elevator control panel fixing base that can eliminate the need for wiring ducts and can reduce the number of parts and the total number of elevator installation work.
[0021]
[Means for Solving the Problems]
In order to achieve the object, a mounting base for an elevator control panel according to the present invention includes a fixing part that fixes a bottom surface of a housing-like elevator control panel, a protruding part that protrudes laterally from the fixing part, A fixing member penetrating hole penetrating through one end of the fixing portion and the other end of the projecting portion 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, the protruding portion protrudes to the side of the fixed portion, and one end of the fixed portion is opposite to the one end. The fixing member penetrates the through hole formed near the other end of the projecting portion.
[0023]
In the elevator control panel fixing stand according to the present invention, the projecting portion is a wiring duct portion arranged from the elevator control panel.
Furthermore, the elevator control panel fixing stand according to the present invention is a frame-structured elevator control panel fixing base in which a wiring routing duct portion of the elevator control panel is formed, in the depth direction of the elevator control panel. A pair of base frames that are arranged opposite to each other and are fixed to the floor surface and that are longer than the depth width of the elevator control panel, column frames raised from one end and the center of each base frame, and the column frames A rectangular frame-shaped fixed frame fixed to the upper end and fixed to the bottom surface of the elevator control panel, and a wiring holder installed between the other ends of the base frame. fixing member hole is formed for the fixing member through which penetrates, the base frame, floor width than the depth width elevator control panel by the fixing member It is secured to, and wherein the portion up to the wire holder which is fixed to the other end from near the center of each base frame is the cabling duct portion which also serves as the cabling for the space of the wiring of the elevator control panel To do.
Furthermore, in the elevator control panel fixing stand according to the present invention, the wiring holder is formed with a wiring through hole through which the wiring of the elevator control panel is passed.
[0024]
DETAILED DESCRIPTION OF THE INVENTION
Next, an embodiment of a mounting base for an elevator control panel according to the present invention will be described with reference to the drawings.
[0025]
FIGS. 1 and 2 show an elevator control panel fixing base of the present invention, FIG. 1 (A) is a front view of the elevator control panel fixed to the fixing 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 a fixing base to which the elevator control panel 21 is fixed via bolts or the like (not shown), 24 a floor concrete, and 23 a floor concrete 24. The cylinder concrete 25 provided on the upper surface of the steel plate 25 is an anchor bolt for fixing the elevator control panel 21 to the floor concrete 24 integrally with the fixing base 22.
[0027]
As shown in FIG. 1C, the fixing base 22 includes a pair of base frames 26 having an L-shaped cross section facing each other, and four support frames raised from one end and the center of the base frame 26. 27, a rectangular frame-shaped fixed frame 28 fixed to the upper end of the support frame 27, a reinforcing frame 29 installed between one ends of the base frame 26, and a wiring holder 30 installed between the other ends of the base frame 26. And a reinforcing side panel 31 installed between the support frame 27 closer to the center.
[0028]
The base frame 26 is formed with fixing long holes 26a through which the anchor bolts 25 pass near both ends thereof, whereby the width of the elevator control panel 21 in the small opening 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 that (corresponding to depth). In addition, a portion extending from the center of the base frame 26 to the wiring holder 30 fixed to the other end serves as a routing duct portion 32 that also serves as a routing space for the wiring 20. Thereby, the wiring holder 30 is formed with a wiring through hole 30a for routing.
[0029]
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 are formed in the fixing frame 28.
[0030]
As shown in FIG. 1A, the anchor bolts 25 correspond to a total of four locations at both ends in the longitudinal direction of the elevator control panel 21 and at both ends in the small edge direction of the elevator control panel 21 as shown in FIG. Placed in 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 base 22.
[0032]
At this time, the direction of the small edge of the elevator control panel 21 is fixed to the fixing base 22 by anchor bolts 25 separated by a distance w wider than its depth. Even if the height H up to the surface of 24 is high, it is possible to ensure a strong fixing strength that prevents the elevator control panel 21 from overturning.
[0033]
In addition, since the fixing base 22 has a wide gap w in the direction of the edge of the anchor bolt 25 and a wiring duct portion 32 for the wiring 20 formed integrally, a dedicated duct (for example, a wiring) The work of installing the measure duct 10) separately from the fixing base 22 can be made unnecessary.
[0034]
【The invention's effect】
The fixing base for the elevator control panel according to the present invention is configured as described above, thereby eliminating the need for a dedicated fixing member for fixing the upper surface of the elevator control panel, and securing the fixing strength. can do.
[0035]
In addition, it is possible to eliminate the need for wiring ducts, and it is possible to reduce the number of parts and the number of work steps for the entire elevator installation work.
