Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a lift 71 for vertically lifting various shrines 1 during the construction of a high-rise building, and a method for using one of the lifts.

When constructing a high-rise building, as the steel frame assembly progresses, it becomes necessary to lift various materials vertically. There is.

In such conventional lifts, left and right guide rails are fixed to the beams of each floor via wall joints, and a sheave is installed at the top of the guide rail to change the direction of the wire rope (-
Attach a series of platforms to support the loaded truck li1, wrap a 1neu V-lobe around the sheave of the other series of vehicles and the sheave installed on the platform, and pull the 7 [1-beams] to the side with a traction machine. By doing so, the loading platform can be rolled up 1 - 1 and 3 times.
The vertical lift of 1 is made to be (i).

However, if you use the conventional lift 1-, the loading platform (
1) The series supporting the instep was attached to the guide rail and the guide (knoll) was used to support the weight of the loading platform, so it was not possible to use a thick and sturdy guide rail. 3. Also, as the steel frame assembly progressed In order to connect the guide 1 knoll to the guide 1 knoll using a separate device (for the guide 1 and the idle rail joint leg), it is necessary to connect the guide 1 knoll to the guide 1 knoll using a separate device, then suspend the series and attach it to the guide 1 knoll again. This required a lot of troublesome work, which required a lot of manpower and time.

The present invention is to support the Sendai hand by the beam of the building through the union so that the weight of the loading platform will not be applied to the guide 1. It is very simple to do (all you need); advance assembly of the sea urchin, guide rail and wall 4I:;\゛, climbing with the self-blade of the continuous stand, assembly of the guide 1 knoll using the j1L stand. , ``Demolition is easy,'' and ``Sea urchin-C1 improves work efficiency.''

The embodiments of the present invention will be described above with reference to the drawings.

In Figure 1 11■, the 9th floor of each floor of the building is assembled at a predetermined interval in the 1A1 direction with respect to the base 1.
2. The right pair of idle rails 3.3 are fixed to the beams via the wall joints 4 (-C).

It is designed to prevent horizontal vibration.

Near the top of the guide rail 3.3, a combination 1, indicated by 8 in its entirety, is installed, and this combination 8 protrudes and retracts to the side, and in the protruding state it becomes ``〕 = right beam'' 2.2. Equipped with an engaging slide beam 9.9, Riffh's Adventure i':FJ
All the weights are carried by the left and right beams 2.2 via the series 8, and the lift rails 3.3 are subjected to lifting loads, resulting in an awkward structure.

When using riff j ~, the series 8 is a slide beam 9.9
The slide beam 9.9 is installed in the main body of the platform so that the platform 8 can pass through the landing path (between the beams) when climbing the platform 8 or dismantling the lift. Climbing of the series 8 is achieved by using a pinion (not shown) installed on the series 8 that engages with a rack (not shown) attached to the guide rail 3.3. The drive device 10
This is done by rotating and driving the unit 8.
A sheave 7 (Fig. 2) for changing the direction of the wires 16 (Fig. 2) from the loading platform 12 and the tensioning device 6 (Fig. 2) is installed. Also, as the assembly progresses, the guide rail 3,
A hanging bracket 11.11 for hanging the wall tether 4 is provided.

There is provided a loading platform indicated by 12 which is rolled up and lowered while being guided by guide rails 3.3. It consists of a lowering knob 1, a gnome 13, a cargo receiving part 1/I, etc., and engages with the guide rails 3, 3, etc., and id [1-15] are provided at two locations on each of the ten kings. In addition, a sheave 7 (Fig. 2) is installed on the loading platform 12 to receive the wire loaf 16 (Fig. 2) from the 1-traction machine 5, the series machine 8, and the tension device 6, and a governor (not shown) is installed on the loading platform 12. It is equipped with a safety feature to prevent falls.

Fig. 2 shows the state in which the wire loaf 16 is hung, and the -JW16a of the wire loaf 16 is removably fixed to the base 1 with a clip or the like.

The loading platform 12 can be moved up and down to read the monthly interest.

In this case, the tensioning device 6 constantly applies a frictional force to the traction machine 5 to move the loading platform 12 up and down at a constant speed. The lifting load is not applied to the left and right beams 2.211" through the gobe series 8 and to the guide rails 33.3.

As the steel frame N"l of the building progresses, in order to fix the joints of the rails, first roll up the pedestal 12 and lower it to the lowest position to release the tension on the wire rows 16 and lower the wires 11 to 16. 19ηf 16 it from the base 1.

The demolition of ~ is done by reverse climbing.

As explained by my son, according to the present invention, the Sendai Φfj1 is supported by the building through the association, and the platform type part does not hang on the guide rail, so it is a very simple guide rail. In addition, the continuous platform can be used for climbing without the need for other equipment, the guide rail can be assembled and disassembled using the continuous platform, and the guide rail can be pre-assembled, so it is possible to The lift can be assembled and dismantled extremely efficiently with a limited number of people.
