Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an apparatus for laterally moving a heavy object, and more particularly to an apparatus for laterally moving a block in a block construction method for constructing a dam embankment.

[0002]

2. Description of the Related Art Conventionally, in order to move a heavy object laterally, a large number of humans push the heavy object in cooperation with each other or use a tool by utilizing the principle of leverage to move the heavy object laterally. It usually depends on human power. For example, there is a block construction method as one of the concrete casting methods for dam embankment construction. In this method, blocks are installed instead of formwork, concrete is cast, and the dam embankment is constructed. This is a construction method. Usually, this block is a precast concrete block (hereinafter referred to as PCaC) manufactured in a factory in advance.
Called B. ). This PCaCB is quite heavy. In this block construction method, PC
To load aCB, the P suspended by crane etc.
After temporarily placing CaCB near a predetermined position, the operator moves the CaCB sideways while finely adjusting the position using a ball, and installs the CaCB at the predetermined position.

[0003]

However, the lateral movement of PCaCB by human power as described above has the following problems. (1) Since PCaCB is very large and heavy, it is very hard work for workers. (2) Since the work is performed at an unstable step on the PCaCB, there is a possibility that the worker may fall.
This is extremely dangerous for the worker, for example, the worker's finger may be pinched between B and PCaCB. (3) Since the operation is performed manually, it is difficult to install the device at a predetermined position and it takes time. (4) Since the worker directly hooks the PCaCB using a bar and works, the PCaCB is sharpened by the tip of the bar.
CB is missing. Therefore, it is necessary to repair the missing part later, which is troublesome and costly. The above-mentioned problems are not limited to the block construction method when constructing the dam embankment, but are common problems when moving heavy objects laterally.

In view of the above, the present invention has been made in view of the above-mentioned problems, and in a block construction method for constructing a heavy material, particularly a dam embankment, a large and heavy block can be easily and safely and smoothly. A heavy-weight lateral pushing device which can be moved laterally while making fine adjustments without damaging the block is constituted.

[0005]

That is, the present invention is a means for solving the above-mentioned problems. As shown in FIGS. 7 and 8, a thin horizontal member extending forward with its base end connected to the base 4 as shown in FIGS. Above the bottom plate 6, an inclined upper plate 9, which is attached to the base 4 so as to be able to move up and down by pivotally supporting the base 4, and whose distal end portion 11 is formed as a thin plate rotatable in the vertical direction, is arranged with its distal ends overlapped. Further, a wedge body 5 whose upper surface is inclined downward in advance is sandwiched between the horizontal bottom plate 6 and the inclined upper plate 9 via a pushing mechanism 1 provided on a base so as to be able to move back and forth. 1 to 3, a pressure receiving member having a surface parallel to the front surface, which is provided appropriately above the distal end of the wedge body 5, as shown in FIGS. 12
And the base end was pivotally mounted on the base 4,
A heavy-weight lateral pushing device characterized in that a reaction force receiving member 13 having a shape engaging with a depression of the device mounting surface is detachably provided.

[0006]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, the present invention will be described in detail based on embodiments shown in the accompanying drawings.

FIGS. 7 and 8 are a side view and a plan view, respectively, of a heavy-weight lifting device, which are known (see Japanese Utility Model Laid-Open No. 4-94309).
As shown in the drawing, the construction of this device is mounted above a thin horizontal bottom plate 6 extending from the base end to the base 4 and extending forward with the base end pivotally supported on the base 4 so as to be able to move up and down. An inclined upper plate 9 having a distal end portion 11 formed of a thin plate rotatable in the vertical direction is disposed with the distal ends thereof superposed on each other. Further, between the horizontal bottom plate 6 and the inclined upper plate 9, the upper surface is previously set to the front. A wedge body 5 that is inclined downward is sandwiched so as to be able to move back and forth via a pushing mechanism 1 provided on a base. When the heavy object lifting device moves or holds the heavy object placed on the floor, it is inserted in advance in the gap between the lower edge of the heavy object and the floor surface, and this portion is required by a jack or the like. This is a device for pushing up to a height at which a tool can be inserted. Naturally, this device cannot push a heavy object sideways. This is because there is no member having a surface for transmitting the lateral force transmitted to the piston, which is the pushing portion, to the heavy object in the lateral direction. This is because there is no member that receives the light.

Therefore, as shown in FIGS. 1 to 3, here, the inclined upper plate 9 of the heavy lifting device is removed,
By providing a pressure receiving member 12 having a surface parallel to the front surface at the tip end of the wedge body 5, one of the above-described conditions is satisfied, and the lateral force transmitted to the piston serving as the pushing portion is applied to the heavy object by the lateral force. It was configured to transmit in the direction. FIG.
FIG. 2 is a side view of a heavy-weight lateral pushing device according to the present invention, and FIGS. 2 and 3 are a plan view and a rear view, respectively. Here, the pressure receiving member 12 is provided appropriately above the tip of the wedge body 5. Because, as shown in FIG.
This is because the front end of the wedge 5 is sandwiched between the heavy object and the floor, so that the wedge 5 can be easily pushed laterally. May be determined as appropriate. The dimensions of each part of the pressure receiving member 12 may satisfy the condition that the lateral force transmitted to the piston can be efficiently transmitted to the heavy object in the lateral direction. Here, as shown in FIG. 2, the width of the pressure receiving member 12 is substantially the same as the width of the wedge 5.

Further, a reaction force is received by providing a reaction force receiving member 13 which is a member for receiving a reaction force against the transmitted lateral force. Here, the reaction force receiving member 13 is shaped to engage with the block hole, and is rotatably mounted with the base end pivotally supported by the base 4. Because, as shown in FIG. 4, by contacting the reaction force receiving member 13 with a surface as close as possible to the vertical surface such as the side surface of the block hole, the reaction force can be efficiently received. This is because it is necessary to be rotatably supported on the shaft. Here, one end surface of the reaction force receiving member portion 13a abuts against the side surface of the block hole, and the other end surface abuts on the upright frame 2 of the base 4 to support the reaction force receiving member portion 13a. Is supported by the tip of the standing frame 2 of the base 4 and balances the lateral reaction force received from the heavy block.
In FIG. 1, one end of the reaction force receiving member portion 13 a in contact with the upright frame 2 of the base 4 has a rounded chipped shape. It is provided so as not to come into contact with the hose connecting portion 7 connected to the hydraulic pump when the tip portion of the standing frame 2 is rotated about the axis. The reaction force receiving member 13 is not limited to this example. Any shape can be used as long as it can freely rotate around the supported shaft. As is clear from the back of the apparatus as shown in FIG. 3, the end of the reaction force receiving member portion 13a has an arc shape, and the reaction force receiving member portion 1 in both horizontal directions of the pushing mechanism 1 is provided.
The reaction force receiving members 13 are formed as a whole by connecting the ends of the reaction force receiving members 3b. The reason why the end portion of the reaction force receiving member portion 13a is arc-shaped is that when the end portion of the reaction force receiving member portion 13a comes into contact with the side surface of the block hole and receives the reaction force, the side surface of the block hole is not damaged. This is because consideration was given to it.

The pressure receiving member 12 and the reaction force receiving member 13
Can be manually attached to and detached from the heavy object lifting device manually. If these are removed and the inclined upper plate 9 shown in FIG. It can be used as a heavy lifting device.

Next, with reference to FIGS. 4 to 6, a description will be given of a method of laterally moving a block using the heavy-weight lateral pushing device according to the present invention in a block construction method for constructing a dam embankment. FIG. 5 is a side view showing the use of the heavy load lateral pushing device according to the present invention in the block construction method for constructing a dam embankment, and FIG. 6 is a plan view thereof. FIG. 4 is an enlarged side view of a main part of FIG. At this time, as shown in FIG. 5, the PCaCB is piled up so as to form a break joint using a crane, that is, the joint of the first PCaCB and the joint of the PCaCB immediately above and below are shifted by half the width of one PCaCB. However, since it cannot be accurately installed at a predetermined position only by lifting with a crane, first, the hole of the target PCaCB and the hole of the PCaCB immediately below are approximately aligned, and the temporary installation is performed in a state of passing through the connecting rebar. . Then, the heavy object lateral pushing device according to the present invention is connected to the target PCaCB.
At the position of PCaCB which is not yet loaded.

The installation of this device is carried out by first lifting the lower end of the PCaCB to be laterally pushed by using a crane and slightly raising the lower end of the PCaCB to form a gap. Of the pressure receiving member 12 is brought into contact with the side surface of the PCaCB. Next, the reaction force receiving member 13 is engaged with the block hole located at the lower part of the device. Specifically, a reaction force receiving member 13 having a shape to be engaged with the block hole is selected, attached to the device, and one end surface of the reaction force receiving member portion 13a abuts on the side surface of the block hole without any gap. It is installed so that the other end of the member portion 13a abuts on the side surface of the upright frame 2 of the base 4 without gap.

When the installation of the apparatus is completed in this way, the hydraulic pump is operated, and the wedge body 5 is moved forward by the piston of the hydraulic cylinder serving as the pushing mechanism via the hose connecting portion 7, that is, the target PCaCB. Extrude horizontally in the direction of. At this time, the flow of the reaction force in the lateral direction includes the pressure receiving member 12, the wedge body 5, the piston of the hydraulic cylinder, the hydraulic cylinder, the standing frame 2 of the base 4, and the reaction force receiving member portion 13.
b, the reaction force receiving member portion 13a. Thus PC
aCB is extruded in the lateral direction, and PCaC
B is installed, but fine adjustment is possible by adjusting the output of the hydraulic pump, and the PCaCB can be moved laterally while visually confirming the position of the PCaCB. There is no danger of pinching your finger.

As described above, using the heavy object lateral pushing device according to the present invention, particularly in a block construction method for constructing a dam embankment, large and heavy blocks can be easily and safely, smoothly and smoothly. Can be moved laterally while making fine adjustments without damaging the.

[0015]

As is apparent from the above description, the present invention produces the following effects when PCaCB is moved laterally in the block method when constructing a heavy object, particularly a dam embankment. (1) Since it does not rely on human power, heavy labor of workers is reduced. (2) There is almost no dangerous work for workers. (3) Since the work is performed by a machine, the work can be quickly and smoothly installed at a predetermined position, which contributes to shortening the construction period and the cost. (4) Since no sharp tools are used, PCaCB is not damaged. For this reason, there is no need for rework and reversal work, which helps to shorten the construction period and reduce construction costs. The effects described above are not limited to the block construction method when constructing the dam embankment, but are common effects when a heavy object is moved laterally.
