Description

  The present invention relates to a heavy structure moving apparatus suitable for use in moving heavy structures such as buildings, houses, and bridges.

  When moving a heavy structure such as a building or a bridge, the weight of the heavy structure portion has conventionally been transferred onto a roadbed material 31 as shown in FIG. 10 via a rolling device composed of a boat plate iron plate, a sanddle, a wedge, and a conforming plate. To the roller rods 32 arranged at appropriate intervals. The roadbed material 31 is a so-called H-shaped steel such as a rail for rail, and a rail clamp and a propulsion jack (both not shown) are provided on the upper plate 31a constituting the roadbed material 31, and the rail clamp is used as a fulcrum. The reaction force was taken from the object load, and the heavy structure was pushed by the propulsion jack to rotate the roller bar 32 and move the heavy structure.

In the conventional heavy structure moving device as described above, it is necessary to change the rail clamp according to the jack stroke and the roller rod according to the amount of movement. The replacement of the rail clamp requires adjusting the jack stroke dimension, removing the wedge, moving the rail clamp, and driving the wedge.
In addition, since the roller rods are changed, it is necessary for the worker to constantly monitor according to the amount of movement.
On the other hand, railroad rails with less versatility are often used as the roadbed material constituting the moving route, but unevenness and errors occur during the installation. In addition, the roller rod 32 is originally disposed so as to be orthogonal to the roadbed material 31 as indicated by a solid line in FIG. May fall off. Due to such a deviation in the direction of the roller rod 32, a difference in how the load is applied, or due to a difference in the method of pushing with another moving device, an eccentric force may act, causing a phenomenon in which the moving devices compete with each other.

The moving device 1 moves in a predetermined direction, for example, the arrow A direction, with the heavy structure 3 placed on the roadbed material 2 laid in advance. As the roadbed material 2, H-shaped steel is applied as shown in FIG. 2, and the number of laying members is freely changed depending on the size and weight of the heavy structure 3. The heavy structure 3 is a building or a bridge, and sometimes a structure having a weight of 7000 t is moved.
When moving the heavy structure 3, the hydraulic jack 5 which is a driving member is driven by hydraulic control, and the movable structure 6 is movably fixed to one end of the upper plate 2a of the roadbed material 2 and is used as a fulcrum. The object 3 is pushed in the direction of arrow A.

That is, although the whole structure of the moving apparatus 1 is shown by FIGS. 1-3, the structure of the principal part is demonstrated with reference to FIGS. 4-6 below.
The flat sliding member 11 referred to in the present invention is disposed on the upper surface of the upper plate 2a constituting the roadbed material 2, and the sliding member 11 is fixed in the first frame 12 having a long shape. Has been. As shown in FIG. 4, the frame 12 is formed with a concave portion in the longitudinal direction at the center, and the sliding member 11 is fitted therein. Note that the lateral width W of the sliding member 11 is smaller than any of the width W1 of the upper plate 2a and the inner width W2 of the frame body 12. However, as shown in FIG. 5, the length L of the sliding member 11 extends over substantially the entire length of the frame 12, but both ends are covered with both ends 12 a of the frame 12.

  The wedge portion 13a of the pushing member 13 is positioned on the upper portion of the frame body 12, the second frame body 14 is positioned on the upper portion, and a flat elastic material 15 is accommodated in the second frame body 14. Has been. As shown in FIGS. 5 and 6, the second frame body 14 is formed in a tray shape with a shallow bottom, and a flat elastic material 15 is accommodated therein. However, the elastic material 15 is not of a size that covers the entire inside of the frame body 12, and a gap G is formed between the elastic material 15 and the protruding frame portion 14 a of the frame body 14 as can be seen from FIGS. 2, 5, and 6. ing. Therefore, as shown by the imaginary line in FIG. 6, the position of the heavy structure 3 may be displaced due to friction or the like during movement, but the position is restricted by hitting the projecting frame portion 14a, and slipping or slipping off during movement is prevented. It is configured to prevent it.

Next, the movable clamp 6 will be described.
The movable clamp 6 is used in a state of being sandwiched between the upper plates 2a as indicated by a solid line in FIG. 1 and an imaginary line in FIG. The movable clamp 6 is formed by forming a steel material into a flat quadrangle. An insertion portion 6a is formed on one side so as to face a wedge-shaped space, and the surface of the movable clamp 6 bites into the upper plate 2a. In order to improve, a serrated tooth mold 6b is formed. The movable clamp 6 is fixed with a connecting shaft 21 that is connected to another movable clamp, and a protrusion 22 formed on the side surface is fixed with a connecting shaft 22 for connecting the hydraulic jack 5. The connection state of the movable clamps 6 by the connection shaft 21 and the connection state of the hydraulic jack 5 by the connection shaft 22 are shown in FIG.

Has been. Further, reinforcing plates 7c for preventing deformation of the plate material 7a are integrally provided on both sides of the upper end portion of the plate material 7a by welding or the like.

On the other hand, the press-fitting member 7b has a shape in which one side is horizontal and the other side is inclined, and a groove portion 7d inclined in the longitudinal direction is formed. When reinforcing the roadbed material 2 with the reinforcing member 7, as shown in FIG. 9, first, the plate material 7a is inserted between the upper and lower plates 2a and 2b, and then the inclined portion 7e formed at the lower end of the plate material 7a is press-fitted member 7b. In this state, the press-fitting member 7b is driven and fixed in the direction of arrow C with a hammer or the like.
The reinforcement member 7 is fixed at appropriate intervals on both sides of the upper and lower plates 2a and 2b. As a result, as shown in FIGS. 1 and 2, the upper and lower plates 2a and 2b are reinforced at appropriate intervals from both sides, and the upper plate 2a is bent and deformed when the weight of the heavy structure 3 is applied. Can be prevented.

Next, the operation of the moving device 1 will be described.
The movable clamp 6 is fixed to the roadbed material 2 as described above, and the paired movable clamp 6 is connected by a connecting shaft 21 as shown in FIG.

Then, as shown in FIG. 1, when the moving device 1 is assembled and the hydraulic jack 5 is driven, the movable clamp 6 is inclined as described with reference to FIG. 7, and the tooth mold 6b bites into the upper plate 2a and is fixed. It becomes a state.
When the hydraulic jack 5 is driven in this state, the pushing member 13 is pushed in the direction of arrow A with the movable clamp 6 as a fulcrum. The lower end of the pressing member 13 is in contact with the end of the first frame 12 as shown in FIGS. Accordingly, the first frame body 12 and the sliding member 11 are integrally moved in the direction of the arrow A, and the heavy structure 3 is moved via the second frame body 14 and the elastic material 15.

During the movement of the heavy structure 3, the sliding member 11 smoothly slides on the surface of the upper plate 2a, and the elastic material 15 holds the heavy structure 3 stably. At this time, the elastic material 15 may move due to a shift in the moving direction or the like, but it does not protrude or fall off by the protruding frame portion 14a.
Accordingly, it is possible to reduce the worker's monitoring work and rework work, and the moving work can be performed efficiently.

  As the sliding member 11, MC nylon (trade name of Nippon Polypenco Co., Ltd.) is suitable, but any material having excellent heat resistance, tensile strength, slidability, etc. can be used.
