[Problem that the invention seeks to solve]

In general, when converting an existing elevator to a new elevator, it is desirable to shorten the period of replacement of the hoisting machine as much as possible in order to shorten the elevator's outage period as much as possible, and it is also desirable to shorten the period of replacement of the hoisting machine as much as possible. Since there will be residents, it is desirable to use construction methods that do not use fire or generate noise. Furthermore, from an earthquake-resistant perspective, it is desirable to lower the center of gravity of the hoist as much as possible, increase the strength of the machine platform, and comply with current regulations.

However, the above-mentioned conventional renewal elevator hoisting machine support device uses cylinder concrete 4
By attaching the anchor 10 to the floor 1a of the machine room 1
However, since it is possible to fix the chipped part 12 against the wall, it becomes necessary to backfill and repair the chipped part 12 with mortar, which takes a long time, generates noise during the chipping work, and also causes damage to the existing machine stand 3. Since the newly installed hoisting machine 8 is supported through the supporting metal 5 and the newly installed machine stand 6, there is a problem that the center of gravity becomes high.

This invention can solve the above-mentioned problems and meet the above-mentioned demands, shorten the construction period, generate less noise, lower the center of gravity of a newly installed hoist, and provide a low-cost product with a small number of parts. The purpose of the present invention is to provide a hoisting machine support device for a recurrent elevator that can be used.

[Means for solving problems]

The hoisting machine support device for a renewal elevator according to the present invention fixes supports that connect existing machine platforms to each other to cast cinder concrete from the top surface of the cylinder concrete or to anchors that are fixed to this and the floor of the machine room. The newly installed hoisting machine is directly supported on the machine stand.

[Effect]

As mentioned above, in the hoisting machine support device for a renewal elevator according to the present invention, the supports that connect the existing machine platforms to each other are cast from the top surface of the cylinder concrete and fixed to anchors that are fixed to this concrete. This eliminates the need for chiseling work, which naturally eliminates the need to backfill and repair the chiseled parts of the cylinder concrete with mortar, resulting in a shorter construction period.
No special tools are required, there is little noise, and the newly installed hoisting machine is directly supported without using a new machine stand on the existing machine stand.
The number of parts is small, and the center of gravity of the newly installed hoist can be lowered.

〔Example〕

An embodiment of the present invention will be described below with reference to FIGS. 1 and 2.

In FIGS. 1 and 2, the same reference numerals as in FIGS. 4 and 5 indicate corresponding parts. In this embodiment, an anchor mounting bracket 9 is supported on the upper surface of the cylinder concrete 4 near the existing machine platform 3 which is installed semi-submerged in the cylinder concrete 4 on the floor 1a of the machine room 1 of the existing elevator. is fixed to the floor 1a side by an anchor 10 such as a resin (chemical) anchor bolt driven from the upper surface of the cylinder concrete 4 to the floor 1a of the machine room 1. The anchor mounting bracket 9 and the support bracket 5 are tightened and fixed so that their positions can be adjusted using bolts 14 and nuts 15 inserted through elongated holes 9a and 5a that are perpendicular to the vertical and horizontal directions, and the support bracket 5 is attached to the existing machine. It is arranged on both ends of the two beams of the stand 3 so as to be perpendicular to them, and the beams are connected by a support 5, and a new hoisting machine is installed on the existing machine stand 3 via a vibration isolating rubber 7. 8 is directly supported and fixed.

In the hoisting machine support device of the embodiment configured as described above, the cylinder concrete 4 that makes the existing machine platform 3 semi-submerged has a thickness of 100 to 150 mm, which is not constant, but the anchor mounting bracket 9 and The support metal 5 is inserted into the elongated holes 9a and 5a, and the bolt 14 and nut 15
By being tightened so that the position can be adjusted, variations in the thickness of the cylinder concrete 4 can be easily coped with. Further, by using a resin anchor bolt as the anchor 10, variations in the thickness of the cylinder concrete 4 can be easily dealt with by cutting the threaded rod as necessary. In addition, if the compressive strength of the cylinder concrete 4 is 100Kg/cm2 or ^more , the tensile strength of the anchor 10 will be about 3000Kg when the pilot hole depth is 100mm, so the resin anchor bolts are not necessarily attached to the slab (concrete) on the floor 1a of the machine room 1. ) and may be fixed in the cylinder concrete 4.
Therefore, by using a resin anchor bolt as the anchor 10, the length can be easily determined according to the thickness of the cylinder concrete 4, and the workability is good and the cost is low. It is sufficient to make a hole of the same diameter in the cylinder concrete 4 or in a part of the floor 1a of the machine room 1, making almost no noise, the hole diameter can be small, and workability is good.

FIG. 3 shows another embodiment of the invention. In FIG. 3, the same reference numerals as in FIGS. 1 and 2 indicate corresponding parts. In this embodiment, one end of the existing machine stand 3 is embedded in the wall 1b of the machine room 1, and one support This is the same as the embodiment shown in FIGS. 1 and 2, except that the metal 5 is directly fixed to the wall 1b of the machine room 1 with an anchor 10 such as a resin anchor bolt driven into the wall 1b. be. In the embodiment shown in FIG. 3, by using a resin anchor bolt for the anchor 10, the waterproof property is improved and there is no fear that the anchor will come off when the compressive strength of the concrete of the wall 1b is low.

〔Effect of the invention〕

As explained above, the hoisting machine support device for a renewal elevator according to the present invention uses a resin anchor-like support that connects existing machine platforms to each other to be driven from the top surface of cylinder concrete provided on the floor of the machine room. Since it is fixed to an anchor, there is no need to provide a hanging part on the cylinder concrete.
There is no need to backfill and repair this hanging part, which shortens the construction period and reduces noise.Furthermore, the newly installed hoisting machine can be directly supported without using a new machine stand on the existing machine stand. Therefore, the number of parts is small and the cost is low, and the center of gravity of the newly installed hoist can be lowered, which is advantageous in terms of earthquake resistance.
