TECHNICAL FIELD OF THE INVENTION
The present invention belongs to the technical field related to lifting a structure using air pressure.
[0002]
[Prior art]
Conventionally, techniques for lifting structures using air pressure include, for example, air casters for small ones, hovercraft for medium-sized ones, and air-raising used for roofing large storage tanks with dome roofs for large ones. The construction method is known.
[0003]
This conventional structure lifting technique is to lift (move upward) the entire structure by applying air pressure to a space below a large and heavy structure such as a dome roof of an LNG tank. is there. The space below the structure is provided with an air supply mechanism for supplying air and applying air pressure to lift the structure, and a seal mechanism for holding the seal even when the structure is lifted.
[0004]
[Problems to be solved by the invention]
In the above-described conventional technique of lifting a structure, since the space to which air pressure is applied is single, when the load distribution of the structure is uneven (for example, the size and height are different on a flat plate). When the building is in a forest, the air pressure must be adapted to the largest load, and it is necessary for the upper part of the space (the floor and bottom walls of the structure) to which only a small load is applied. As described above, there is a problem that air pressure is applied. In this case, the upper wall of the space may be locally deformed.
[0005]
In order to solve this problem, it is conceivable to provide high rigidity over the entire upper wall of the space. However, when the rigidity of the entire upper wall of the space is increased, a new problem that the construction cost of the structure is increased occurs.
[0006]
The present invention has been made in view of such problems, without increasing the construction cost, a method of lifting a structure that can lift the structure by preventing deformation of the upper wall of the space, It is an object to provide a lifting device for this structure.
[0007]
[Means for Solving the Problems]
In order to solve the above-mentioned problems, a method for lifting a structure according to the present invention employs the following means.
[0008]
That is, as described in claim 1, an upper wall on which a structure is installed, a compartment defined by a partition wall on a lower surface of the upper wall, and a lower end opening peripheral edge serving as a ground edge, and a ground edge of the compartment. A sealing mechanism for each of the compartments provided, an air supply mechanism connected to each of the compartments to apply air pressure to the compartments, and a lifting amount detecting means for detecting a lifting amount of each structure in each of the compartments, In a lifting device for a structure comprising a control means for controlling an air supply mechanism in cooperation with a lifting amount detecting means and adjusting an air pressure applied to each compartment, the respective structures are equally large, and on a lower surface of the upper wall.

BEST MODE FOR CARRYING OUT THE INVENTION
Hereinafter, an embodiment of a structure lifting device according to the present invention will be described with reference to the drawings.
[0018]
1 to 5 show an embodiment (1) of a structure lifting device according to the present invention.
[0019]
In this embodiment, a structure 1 in which three independent buildings 11, 12, and 13 having different heights (loads) are separately constructed on a common base 14 and installed on an installation surface 2 such as the ground surface. Are applied.
[0020]
The base 14 of the structure 1 is surrounded by the upper wall 14a and the outer peripheral wall 14b and forms a space in which the air pressure P is applied. Further, inside the base 14 constituting the space, the compartment 3 is formed by the partition wall 14c. The compartment 3 covers the entire surface of the upper wall 14a so as to be able to cope with a change in the construction position of the buildings 11, 12, and 13 and to be able to disperse and install a plurality of structures at arbitrary positions on the upper wall 14a. It is divided into a large number of rooms like a lattice. The upper wall 14a of the base 14 is supported by a column 14d having an upper end fixed to the upper wall 14a and the other end freely grounded.
[0021]
A seal mechanism 4 is provided between the outer peripheral wall 14 b and the lower part of the partition wall 14 c of the base 14 of the structure 1 forming the compartment 3 and the installation surface 2. The seal mechanism 4 is composed of an expandable and contractible block filled with a fluid, and seals between the compartments 3 and between the compartments 3 and the installation surface 2 even when the structure 1 is lifted. Can be held.
[0022]
As shown in FIG. 2, each compartment 3 is connected to an air supply mechanism 5 for supplying air and applying an air pressure P for lifting the structure 1. The air supply mechanism 5 includes an air compressor, a flow control valve, a pressure control valve, an opening / closing valve, and the like, and is capable of adjusting the air pressure P applied to each compartment 3.
[0023]
As shown in FIG. 2, each compartment 3 is provided with a lifting amount detecting means 6 for detecting a load F of the structure 1 applied to each compartment 3 as a lifting amount S of the base 14 of the structure 1. . The lifting amount detecting means 6 is composed of a distance sensor or the like using ultrasonic waves, and is installed on the upper wall 14a of the base 14 of the structure 1 to measure the distance from the installation surface 2. .
[0024]
The air supply mechanism 5 and the lifting amount detecting means 6 are connected via the control means 7. The control means 7 controls the air supply mechanism 5 based on the lift amount S of the base 14 of the structure 1 in each compartment 3 detected by the lift amount detection means 6, and controls the air pressure P applied to each compartment 3. adjust.
[0025]
According to this embodiment, prior to the movement, the loads Fa, Fb, Fc, and Fd applied to the respective compartments 3 from the buildings 11, 12, 13 and the base 14 of the structure 1 are roughly calculated, and the structure 1 is appropriately moved. The air pressures Pa, Pb, Pc, and Pd applied to the respective compartments 3 from the air supply mechanism 5 required to raise the height to an appropriate height are set in consideration of supply loss, leakage, and the like.
[0026]
At the time of lifting, air pressures Pa, Pb, Pc, and Pd set in each compartment 3 are applied from the air supply mechanism 5.
[0027]
The structure 1 in which the air pressures Pa, Pb, Pc, and Pd are respectively applied to the compartments 3 is gradually lifted as a whole. At this time, basically, the upper wall 14a of the structure 1 in each of the compartments 3 is lifted uniformly, but the lifting amount S is precisely measured by the lifting amount detecting means 6. This measurement data is transmitted to the control means 7. When an error occurs in each of the lifting amounts S due to various factors, the control means 7 increases the supply amount of air to the compartment 3 having a relatively small lifting amount S to increase the lifting amount S. Control for reducing the supply amount of air to the relatively large compartment 3 is executed.
[0028]
As a result, the air pressure P applied to each compartment 3 of the structure 1 to be lifted is finely adjusted from the setting, so that the upper wall 14a of the base 14 of the structure 1 causes local deformation. Instead, the entire structure 1 can be evenly lifted. Therefore, the buildings 11, 12, and 13 do not tilt when the structure 1 is lifted.
[0029]
When the structure 1 is lifted, there is no need to perform construction for increasing the rigidity of the entire upper wall 14 a of the base 14 of the structure 1. Therefore, the construction cost of the structure 1 is reduced.
[0030]
The lifting configuration including the lifting of the structure 1 is useful for repair and inspection of the surroundings of the structure 1 and the piping system. It is also possible to adopt a movement mode in which the buildings 1, 12, and 13 of the structure 1 are horizontally moved while maintaining the lifting of the structure 1 for lighting or relocation. In the case of adopting a movement form of horizontal movement, a carriage and wheels for movement are temporarily or permanently installed on the base 14 of the structure 1.
[0031]
In addition, even if the buildings 11, 12, and 13 of the structure 1 are changed by new construction, remodeling, extension, demolition, and the like, and the loads Fa, Fb, Fc, and Fd applied to the respective compartments 3 are changed, they are added to the respective compartments 3. This can be dealt with by changing the settings of the air pressures Pa, Pb, Pc and Pd.
[0032]
FIG. 6 shows an embodiment (2) of a method and a device for lifting a structure according to the present invention.
[0033]
In this embodiment, the compartments 3 are constructed in accordance with the buildings 11, 12, and 13 in which the structures 1 are constructed. That is, the space of the portion of the structure 1 where the buildings 11, 12, and 13 are not constructed is one continuous compartment 3. Further, the same sealing mechanism 4, lifting amount detecting means 6, and control means 7 as those in the above-described embodiment (1) are provided. As the air supply mechanism 5, a mechanism capable of applying air pressures Pa, Pb, Pc, and Pd corresponding to the loads Fa, Fb, Fc, and Fd of the constructed buildings 11, 12, and 13 is selected. Have been equipped.
[0034]
According to this embodiment, since the compartment 3 is not unnecessarily partitioned, the construction cost of the structure 1 is further reduced. In addition, since the air pressures Pa, Pb, Pc, and Pd of the air supply mechanism 5 have already been set, when the structure 1 is lifted, each zone is separated from the buildings 11, 12, 13, and the base 14 of the structure 1. It is not necessary to roughly calculate the loads Fa, Fb, Fc, and Fd applied to the compartment 3 and to set the air pressures Pa, Pb, Pc, and Pd of the building 1. Further, since the air supply mechanism 5 having a larger scale than necessary is not installed in each of the compartments 3, the equipment scale of the air supply mechanism 5 is reduced.
[0035]
The other functions and effects are substantially the same as those of the first embodiment.
[0036]
As described above, in addition to the illustrated embodiment, a plurality of compartments 3 can correspond to one building 11, 12, 13 of the structure 1.
[0037]
Furthermore, it is also possible to select a flexible skirt as the seal mechanism 4.
[0038]
【Example】
The above-described embodiment is preferably applied to the entire movement of various buildings, amusement parks where amusement products stand, and theme parks.
[0039]
【The invention's effect】
As described above, the structure lifting device according to the present invention adjusts the air pressure applied in accordance with the load of the structure applied to each compartment that divides the space, and locally deforms the upper wall of the space. This eliminates the need for construction that raises the rigidity of the entire upper wall of the space without causing any other problems, and has the effect of preventing deformation of the upper wall of the space and raising the structure without increasing construction costs. .
[0040]
In addition, the air pressure applied to each compartment that divides the space in accordance with the load distribution of the structure is adjusted to prevent local deformation of the upper wall of the space, and the rigidity of the entire upper wall of the space Therefore, it is possible to prevent the upper wall of the space from being deformed and raise the structure without increasing the construction cost. In addition, since the compartments are not unnecessarily divided, there is an effect that the construction cost of the structure is reduced.
[0041]
Further, the structure lifting apparatus according to the present invention can be implemented without impairing the effect of the above-described structure moving method according to the present invention. In addition, the lifting amount detecting means is provided for each compartment. Therefore, even if the building of the structure is frequently constructed, remodeled, expanded, or dismantled, the load applied to each compartment can be reliably detected.
[0042]
In addition, since the compartments are not unnecessarily divided, there is an effect that the construction cost of the structure is reduced. Further, since the air pressure of the air supply mechanism has already been set, there is an effect that it is not necessary to roughly calculate the load applied to each compartment from the structure when setting up the structure and set the air pressure of the structure.
