Abstract

PURPOSE:To enable deviation in X, Y directions of buildings to be absorbed by providing a connecting part of pipings between two buildings so as to absorb a phase shift between buildings and forming a piping route into a U shape so as to face both X and Y directions. CONSTITUTION:When a building 1 and a building 2 are moved in different phases, a piping 51 is fixed by a piping supporting stand 71 and transmitted to a piping 52 through a piping connecting tool 81. At this time, the piping supporting stand 71 is fixed on the building 1 side, while a piping supporting stand 73 is fixed on the building 2 side. Since the piping connecting tools 81 to 83 can be allowed to the specific angle of mutual piping, vibration between the buildings 1, 2 and phase shift caused by oscillation can be absorbed by the piping connecting tools. That is, the piping connecting tools are valid for connection of an expansion joint part. Moreover, a check part for checking the connecting tools provided between the buildings 1, 2 is provided since confirmation for oil leakage in the piping connecting tools is required. Thus, the phase shift in swing in X and Y directions between two buildings can be absorbed.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a hydraulic pipe connecting a unit of a hydraulic elevator and a jack.

[0002]

2. Description of the Related Art Hydraulic pipes for hydraulic elevators are generally piped between a machine room unit in the same building and a jack of a hoistway, and are firmly fixed with brackets on the way. Normally, even if the building sways, the machine room and hoistway sway in the same way, so no special measures are required. Therefore, piping between the unit and the jack is the shortest route and fixed to the building without any problem (Japanese Utility Model Publication No. 52-51514). Conventionally, as shown in Fig. 1, the piping between buildings 1 and 2 was simply connected by a straight pipe. When the pipe penetrates each wall of the building 1 and the building 2, a fireproof partition plate is provided on both sides of each wall, in which,
It is stipulated that the wall-thickness part should be filled with incombustibles, etc., and the piping does not move easily due to its structure. The expansion joints of the buildings 1 and 2 originally try to absorb those having different phases when the buildings 1 and 2 vibrate or sway, and are cracked only by a straight pipe, and in the worst case, destroyed.

[0003]

One of the features of the hydraulic elevator is that the machine room does not have to be located directly above the hoistway as in the rope type elevator, and can be located anywhere.

One of the recent building structures is an expansion joint in which two spaces are provided in the joints between the buildings so that cracks do not occur even if each building moves a little.

In such a building, when the machine room is installed in one building and the hoistway is installed in the other building, forces having different phases are applied to the hydraulic pipes connecting the units in the machine room and the jacks of the hoistway. In this case, it is necessary to install a pipe in the structure that absorbs the phase shift between the two buildings to prevent the pipe from breaking.

[0006] It is unclear whether the piping of the joint portion of the building can absorb the phase shift between the buildings even if the piping is slightly "bent" with a single piece.

[0007] A commonly used pipe connector is made of rubber, and can withstand bending up to a certain value without breaking.

An object of the present invention is to absorb the displacement of the building in the X and Y directions.

[0009]

In order to achieve the above object, a pipe connecting portion is provided between two buildings so as to absorb the phase shift between the buildings, and the pipes are opposed to each other in the X and Y directions. The piping route is U-shaped so that it can be done.

According to the conventional method, this achieves the purpose of pumping the oil by piping between the unit and the jack at the shortest distance, and the piping is only firmly fixed to the building by the bracket. According to the present invention, in order to absorb the phase shift between the two buildings and also to cope with the phase shift in any of the X and Y directions, the pipe route between the two buildings has a U-shape, and a pipe connecting portion is provided. This is in consideration of which side of the building the piping bracket is fixed to. Further, in the conventional method, a straight pipe is used between buildings to minimize the pipe length and no connecting portion is provided, but since the present invention has the connecting portion, the inspection port is required.

[0011]

[Function] First, the piping to be passed between the hydraulic unit and the jack is first, the piping route is U-shaped between the two buildings, and second, at least one pipe connecting portion is provided on each straight line portion. Depending on whether it is fixed to the building on the side, phase shift between buildings can be handled in both the X and Y directions.

[0012]

The present invention will be described below with reference to the embodiments shown in the drawings.

FIG. 2 shows the piping of the same part of the present invention. Figure 3
6 to 6 show details of the piping of the present invention.

FIG. 2 shows the piping system of the expansion joint portion of the building according to the present invention.

FIG. 6 shows the relationship between the currently used pipe and the pipe connector, and since the inside of the connector 81 is made of rubber, the rubber is applied to the pipe 51 by applying pressure to oil. , 52, so that it can be bent slightly. The maximum bending dimension is L, and the angle is α degrees. This bending dimension, the maximum L and the angle α are to be utilized in this expansion joint.

A description will be given with reference to FIG.

Piping 5 for transmitting the pressure oil discharged from the jug 3
Is arranged in a U-shape through the wall penetrating portion 9 on the building 1 side, and is connected to the unit 4 through the wall penetrating portion on the building 2 side.

3 to 5 show piping between the wall penetration 9 of the building 1 and the penetration 2 of the building 2. 51-
Reference numeral 53 is a pipe, 71 to 73 are pipe supports, and 81 to 83 are pipe connectors.

In FIG. 3, the pipe 51 from the building 1 side is connected to the pipe 52 on the building 2 side through a U-shaped route as shown in the figure in a normal state.

Now, when the buildings 1 and 2 move in different phases, the pipes 51 to 53 are in the state shown in FIG. That is, the pipe 51 is fixed by the pipe support 71 and transmitted to the pipe 52 via the pipe connector 81.

At this time, the pipe support base 71 is moved toward the building 1 side,
3 is fixed to the building 2 side. The support 72 is fixed to the near side of the support, in this case the building 2. By doing so, as described above, the pipe connectors 81 to 83 can tolerate the α angle between the pipes, and therefore the pipe connector can absorb phase shifts such as vibration and shaking between the buildings 1 and 2. That is, it is effective as a connection of the expansion joint section. The connector 82 is effective when the phase shift is further large. When the phase shift exceeds the allowable value of the pipe connector, the pipe connector may be spoiled as in the above example.

Generally, the building interval in the expansion joint portion is small. Since it is necessary to confirm oil leaks and the like in the pipe connection tool, an inspection port 6 is provided to check the connection tool provided between the buildings 1 and 2.

In this way, the phase difference of the shaking of the two buildings of the expansion joint can be absorbed in both the X and Y directions.

Although the present invention has been described with respect to the phase difference due to the shake in the horizontal direction, it can be applied to the subsidence in the vertical direction.

[0025]

According to the present invention, a pipe route is constructed 1.
Phase expansion of the expansion joint part by making the U-shape at the expansion joint part of 2 and fixing one to the building 1 side and fixing the other to the building 2 side and arranging the required number of pipe connectors in the middle Can be absorbed.
