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 (none of which are 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 load of the object, and the heavy structure was moved by pushing the heavy structure with the propulsion jack, thereby rotating 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.

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 the 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.

What is in the position of X is inclined as indicated by an arrow Y, and the teeth 6b bite into the upper side surface and the lower side surface of the upper plate 2a and become fixed.
Therefore, the stronger the pressurization by the hydraulic jack 5, in other words, the heavier the heavy structure 3 is, and the stronger the heavy structure 3 can be surely pushed.

Next, the reinforcing member 7 will be described.
As shown in FIGS. 8 and 9, the reinforcing member 7 includes a trapezoidal plate material 7a and a press-fitting member 7b. The plate 7a is inserted in the vertical direction between the upper plate 2a and the lower plate 2b as indicated by an arrow B in FIG. 8, and the vertical dimension is set slightly smaller than the size between the upper and lower plates 2a, 2b. 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 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 and the like can be used.
