Description

  The present invention relates to a moving method for a structure used when a structure such as a building is supported on a moving body and is moved to a nearby place along a ground by a propulsion device.

  In general, when storing a part or all of an existing building after moving it to a nearby location, after cutting a pillar that supports the existing building and interposing a moving body on the cut part of the pillar A construction method is adopted in which the existing building is moved horizontally along the ground with a hydraulic jack or the like.

  By the way, as one kind of such moving method, a plurality of rails are laid from the lower part of the moving existing building to the moving destination, a supporting bed is installed under the foundation of the existing building, and the rail and the supporting bed are A device using a roller device in which a large number of roller bars are arranged between them and the existing building is moved in the horizontal direction by rolling of the roller rods is known. Here, the rail is fixed on a rail foundation or a loading platform made of a ground firmly pressed, a concrete plate or the like constructed on the ground.

According to the moving method using the roller device (moving body), since the roller rod rolls on the fixed rail, it is not affected by the unevenness of the moving surface, and the roller rod moves because it has excellent straightness. High accuracy and suitable for relatively long distance movement.
However, the moving method has a problem that it takes a lot of labor and time for the work of installing the pressure plate, the work of laying the rails, or the work of refilling the roller bars.

  In addition, when the existing building is a large building such as a reinforced concrete structure, the load received by one pillar increases, but the area where one roller bar contacts the rail, etc. is small. Because of the small load resistance, a large number of roller devices are required for each column. As a result, in order to install the roller device, it is necessary to enlarge or reinforce the basic portion around the column, and there is a problem in that it is difficult to reassemble the roller rod.

  On the other hand, as a method for moving a large building with a high load, there is a method of installing a sliding device (moving body) under the foundation of the above building. A traveling method or a sliding method for a newly constructed steel structure. It is used in etc. In the sliding devices used in these moving methods, the area that contacts the sliding surface of one sliding material is large, and therefore the load resistance per area in the sliding device is large, so that the sliding device can be made small and the sliding device Since the reinforcement of the foundation supporting the apparatus is small and the operation of moving the roller rod is not required, it is particularly suitable for moving heavy objects.

However, in the above moving construction method, it is necessary to ensure a predetermined smooth surface over the entire surface under the foundation of the structure, so that it is generally difficult to use it for a house of an existing structure. was there.
In addition, since the sliding device has a larger friction coefficient than the roller device, the propulsion device for movement is enlarged, and since the difference between the static friction coefficient and the dynamic friction coefficient is large, it is extremely difficult to control the start of movement. There was a problem.

  Furthermore, since the above-mentioned sliding device is inferior in straight running performance, it has been necessary to separately balance it with a wire or to provide a guide rail. In particular, when the structure is rotated around the center of rotation, a large number of the guide rails are installed to guide the structure, or a jack for correcting the direction of the center of rotation is separately installed. In order to increase the movement accuracy, it is necessary to perform fine control, and the work is complicated.

  In order to solve this problem, it would be preferable to have a method for supporting the structure at the center of rotation so that the moving accuracy can be easily secured. When it is difficult to hold a rotation shaft that can withstand, and the rotation center is located outside the structure, it cannot be handled.

  The present invention has been made in view of the above circumstances, and even a large structure can move smoothly and accurately, simplify the work, reduce the work period, and reduce the movement cost. It is an object of the present invention to provide a method for moving a structure that can be made inexpensive and that allows an existing structure to be rotationally moved with high accuracy around its outer rotation center. It is.

  In order to solve the above-mentioned problem, the invention according to claim 1 is the movement of the structure in which the propulsion device moves the structure along the ground after the plurality of pillars supporting the structure are supported by the moving body. In the construction method, a part of the plurality of pillars is supported by a first moving body having rectilinearity, and the other group of pillars is more per moving body area than the first moving body. It is characterized by being supported by a second moving body having a large load resistance.

  The invention according to claim 2 is characterized in that the first moving body is a roller device and the second moving body is a sliding device.

  The invention according to claim 3 is the invention according to claim 1 or 2, wherein the structure is an existing structure, and a plurality of pillars supporting the structure are cut, and the structure is After the first or second moving body is interposed in the pillar cutting part, the existing structure supported by the pillar by the propulsion device is moved along the ground.

  Furthermore, the invention according to claim 4 is supported by the column group supported by the first moving body and the second moving body in the invention according to any one of claims 1 to 3. The column groups are alternately arranged in a direction orthogonal to the moving direction of the structure.

  According to a fifth aspect of the present invention, in the invention according to any one of the second to fourth aspects, the structure is rotated around the rotation center, and the roller device is rotated along the axis of rotation of the roller rod. The extension line is arranged so as to pass through the center of rotation, and the invention according to claim 6 is characterized in that the center of rotation is located outside the structure. To do.

  In the invention according to any one of claims 1 to 6, the straightness at the time of movement is ensured by the first moving body (for example, roller device) that supports a part of the plurality of pillars. In addition, the load resistance can be improved by the second moving body (for example, a sliding device) that supports the other column group. For this reason, it becomes possible to move smoothly and accurately even for a large structure that is heavy in weight by simple construction. Further, as in the invention according to claim 3, when the structure is an existing structure, a plurality of pillars supporting the structure are cut, and the cut portions of the pillars It can be easily applied by interposing the first or second moving body.

  At this time, as in the invention described in claim 4, the column group supported by the first moving body and the column group supported by the second moving body are orthogonal to the moving direction of the structure. If it is alternately arranged in the direction to be moved, the straightness and supporting load can be distributed more evenly in the direction orthogonal to the moving direction of the structure, so that the moving accuracy can be further improved. This is preferable.

  In particular, as in the invention described in claim 5, when the structure is rotated about the rotation center, the roller device is arranged so that the extension line of the rotation axis of the roller rod passes through the rotation center. By arranging, it is possible to cope easily without taking measures such as installing a rotating shaft that is difficult to achieve separately. Therefore, the present invention is particularly effective when applied to the case where the center of rotation is located outside the structure as in the invention described in claim 6.

Hereinafter, based on FIGS. 1-11, one Embodiment of the moving method of the structure based on this invention is described.
In the present embodiment, as shown in FIG. 1, an existing building (structure) 1 to be preserved satisfies the wall receding line and enables external mountain retaining work. This is applied when the maximum arc length is moved about 1 m around the center of rotation.

  The moving method of the existing building will be described in sequence with reference to the flowchart shown in FIG. 2 and FIGS. 3 to 11 related to the respective steps. First, as shown in FIG. 2 is constructed, and a temporary housing 5 for moving body installation is constructed on the foundation 4 below the pillar 3. Next, as shown in FIG. 4, a temporary jack 6 is installed on the foundation 4, and a temporary steel material 7 is installed on the temporary jack 6 and connected with bolts.

  And after making the temporary jack 6 effective and temporarily receiving the frame load acting on the column 3 through the temporary steel member 7, one of all the columns 3 supporting the existing building 1 A predetermined portion of several pillars 3 is cut with a wire saw. At this time, the displacement is measured by the displacement meter 8. Note that the column 3 shown on the left side of FIG. 4 has a cut and removed portion 3a from the middle to the bottom of the column 3 because a sliding device is installed in a later process. On the other hand, in the column 3 shown on the right side in the drawing, since the roller device is installed in a subsequent process, the substantially entire length under the beam is the cut and removed portion 3b.

In this way, after the predetermined portion of the pillar 3 of the existing building 1 is cut and removed, as shown in FIG. 5, the sliding device (second moving body) 10 or the roller device (first device) is provided at the cut portion of the pillar 3. 11) is installed.
Here, as shown in FIGS. 6 and 7, the sliding device 10 has a plate 12 fixed flatly on the upper surface of the temporary housing 5 via a non-shrink mortar 13, and slides on the contact surface on the plate 12. Nylon excellent in property is affixed, and the plate 14 fixed to the column 3 side is provided movably. In addition, the code | symbol 15 is a jack for resisting the load which acts from the pillar 3 in the figure.

  In addition, as shown in FIG. 8, the roller device 11 has a loading platform 16 combined with H-shaped steel fixed to the upper surface of the temporary housing 5, and a plurality of rails 17 on the upper surface of the loading platform 16. Are laid in the left and right direction at equal intervals, and a plurality of roller rods 18 are provided on these rails 17 so as to be freely rollable. A load carrier 19 is installed. Here, in the roller device 11, the extended line of the rotation axis of the roller rod 18 is disposed so as to pass through the rotation center shown in FIG. 1 or FIG.

  And next, the load of the said pillar 3 is removed by removing the temporary jack 6 and the temporary steel material 7 with respect to the one to several pillar 3 which installed the said sliding apparatus 10 or the roller apparatus 11 mentioned above. Move to sliding device 10 or roller device 11. At this time, the portion where the sliding device 10 and the roller device 11 are installed is vulnerable to a horizontal load, and therefore, as shown in FIG. A temporary vertical brace 20 is installed to reinforce the horizontal load.

  The temporary vertical brace 20 is an H-section steel 20a integrated with a jack 20b. The end of the H-section steel 20a is joined to the pillar 2 and the beam of the existing building 1 via the preparation material 20c, and the jack. The non-shrink mortar 20d is filled and cured between 20b and the foundation 4 to be installed between the existing building 1 and the foundation 4.

  Next, the existing building 1 to be moved is supported by sequentially repeating the steps shown in FIGS. 3 to 9 for the other pillars 3 on which the sliding device 10 or the roller device 11 is not installed. The sliding device 10 or the roller device 11 is installed for all the pillars 3 that have been used.

And the jacks 21 and 22 used as a propulsion apparatus are arrange | positioned at the sliding apparatus 10 and the roller apparatus 11 of a predetermined location.
That is, as shown in FIGS. 6 and 7, for the sliding device 10 at a predetermined location, a plate on the temporary housing 5 is used to cause the plate 14 to slip by causing a reaction force between the plates 12 and 14. 12 is installed between the H-shaped steel 23 fixed to 12 and the H-shaped steel 24 fixed on the plate 14 on the column 3 side, so that the existing building 1 can be installed by the jack 21. Can be pressed in the direction of the arrow in the figure, which is the moving direction.

  Moreover, as shown in FIG. 8, about the roller apparatus 11 of a predetermined location, between the loading platform 16 fixed to the temporary housing 5 side and the loading platform 19 installed in the cut | disconnecting lower surface side of the pillar 3, it is jack (propulsion). By installing the device 22, the jack 22 can press the existing building 1 in the direction of the arrow in the figure, which is the moving direction.

FIG. 10 shows the arrangement of the sliding device 10 and the roller device 11 installed on the pillar 3 of the existing building 1 and the installation positions of the propulsion devices 21 and 22.
As can be seen in the figure, in this embodiment, five groups of three pillars having the largest turning radius farthest from the center of rotation are supported by the sliding device 10, and three of the three groups of pillars inward of the turning radius are supported. Are supported by the roller device 11, the column 3 group is sequentially supported by the sliding device 10 from the column 3 group toward the rotation center side, and the column 3 group is supported by the roller device 11. Are arranged alternately.

  Thereby, the column 3 group supported by the sliding device 10 and the column 3 group supported by the roller device 11 are substantially alternately in the direction orthogonal to the rotational movement direction of the existing building 1, that is, the radial direction of the rotational movement. Is arranged. Moreover, in this embodiment, in order to rotate and move the existing building 1 having a large aspect ratio in a plan view in a direction perpendicular to the longitudinal direction, the movement direction of the outer peripheral portion of the existing building 1 is reliably controlled. In view of the fact that the desired rotational movement can be smoothly performed as a whole, the roller device 11 having excellent linearity is disposed in the vicinity of the both ends in the longitudinal direction and in the central portion.

  Then, after the above steps are completed, as shown in FIG. 11, the jacks 20b of all the temporary vertical braces 20 are retracted, the non-shrinking mortar 20d is removed and released, and the existing building 1 is connected by the wire 24. Hold it on the side. Next, the jacks 21 and 22 are operated stepwise to rotate the existing building 1 to a predetermined position around the rotation center, thereby completing the moving operation of the existing building 1.

  As described above, according to the moving method of the existing building 1 having the above-described configuration, a part of the plurality of columns 3 of the existing building 1 is supported by the roller device 11 during the movement, and the roller rod is used. By arranging so that the extension line of the 18 rotation axes passes through the center of rotation, the straightness of the rotational movement is ensured, and the other columns 3 groups are supported by the sliding device 10 to improve the load resistance. Can be made.

  For this reason, even when the large existing building 1 which is heavy is rotated around the rotation center located outside the existing building 1, measures such as installation of a rotating shaft and large-scale guide means which are difficult to realize are provided. Therefore, it is possible to move smoothly and accurately by simple construction.

  At this time, since the three groups of columns supported by the roller device 11 that is particularly excellent in straight running performance are arranged in the vicinity and the center of both ends in the direction orthogonal to the rotational movement direction of the existing building 1, the existing building 1 In the radial direction of the rotational movement, the straightness and the load resistance can be distributed more evenly, and the movement accuracy of the existing building 1 as a whole can be further improved.

  In the above embodiment, the structure moving method according to the present invention has been described only when applied to the case where the existing building 1 is rotated around the rotation center located on the outside of the existing building 1. However, the present invention is not limited to this, and the present invention can be similarly applied to a case where a newly built structure is rotated and a new structure or an existing structure is moved linearly.

  It can be used when a structure such as an existing building is supported on a moving body and moved to a nearby place along the ground by a propulsion device.
