Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a casting device for large-diameter steel plate cells that are previously formed into an integral structure.

When constructing sea walls, quay walls, embankments, etc. using steel plate cells,
Steel plate cells are large monolithic structures that are not sufficiently rigid, making them difficult to pour. Conventionally, a series of operations such as digging the site where they are placed and backfilling them after sinking is required, which is time-consuming and difficult. However, since the work takes a long time, if excessive wave pressure or the like is applied due to a sudden change in weather conditions during this period, there are additional difficulties such as the need to install special measures on the steel plate cells.

On the other hand, when constructing quays, etc. where ships of various sizes are moored, using steel plate cells, it is necessary to cast various steel plate cells with different diameters or depths depending on the location of the quay and the purpose of use. However, there is a problem in that it is necessary to prepare a plurality of pouring devices suitable for the diameters of various steel plate cells, which increases the cost of the equipment.

Therefore, the present invention has been devised to solve the above-mentioned problems of the conventional art. The present invention applies a vertical vibration force of up to 100 degrees to allow steel plate cells to be cast extremely easily and rapidly, and also enables steel plate cells with various diameters to be cast with a single casting device. The object of the present invention is to provide a steel plate cell driving device that can adjust the number of vibration generators in accordance with the shape and dimensions of the steel plate cell or its driving conditions.

That is, the present invention arranges a required number of vibration generators at predetermined intervals, preferably at equal intervals, on an annular frame having a shape substantially similar to the upper edge of a steel plate cell, and synchronizes and interlocks each of the vibration generators. A plurality of steel plate cell support chucks are arranged at predetermined intervals, preferably at equal intervals, on the lower surface of the annular pedestal, and furthermore, the annular pedestal is shaped by a plurality of blocks that can be combined with each other. It is constructed by making the size of the annular frame changeable by combining blocks.

Embodiments of the present invention will be described below with reference to the drawings.

First, in the embodiment of the present invention shown in FIGS. 1 to 3, reference numeral 1 denotes a circular or polygonal annular frame having a shape almost similar to the upper edge of the steel plate cell 2. On the side are hydraulic chucks 3, 3 that support the upper edge of the steel plate cell 2.
... are arranged at equal intervals along the circumferential direction of the steel plate cell 2.

These hydraulic chucks 3, 3, .
It is connected to via a hydraulic hose 6 and is operated by a hydraulic device 5.

7, 7... are vibration generators arranged at equal intervals on the annular frame 1, and each of the drive shafts of these vibration generators 7, 7... is a horizontal axis, and a universal joint 8, 8...
and are interlocked and connected via transmission shafts 9, 9... provided between each drive shaft, and each vibration generator 7, 7... is configured to be completely synchronized and interlocked. .

Next, the annular pedestal 1 has three types of small blocks 1 that can be combined.
a, 1 b t 1 c, a vibration generator 7 is attached to the upper part of the small block 1a, and a hydraulic chuck 3 is attached to the lower part of the small block 1a.A transmission shaft 9 and a transmission shaft 9 are attached to the upper part of the small block 1b. A hydraulic chuck 3 is attached to the lower part of the bearing 10, and the hydraulic chuck 3 is further attached to the lower part of the small block 1c.

In addition, since the small block 1c needs to be replaced according to the diameter of the annular pedestal 1, several types of small blocks 1c are prepared.

At the joints where these small blocks la, 1b, and 1c are assembled, in order to prevent displacement due to vibration, there are corresponding cross-shaped concave portions 20A and convex portions 2, as shown in FIG.
OB is shaped, positioned in the vertical and horizontal directions, and tightened with a bolt passing through the bolt hole 21.

Furthermore, the hydraulic chuck 3 to be attached to the lower part of the small blocks 1 a t 1 b t 1 c is attached to the elongated hole provided in the lower part of the small blocks 1 a , 1 b t 1 c, as shown in FIGS. 5 and 6. 22 is movable radially within the range of the chuck movement length L, and is tightened and fixed by bolts 23A of the bolted back plate 23.

Here, in response to a change in the diameter of the steel plate cell 2, the size of the annular frame 1 is changed by the combination of these small blocks 1 a > 1 b > 1 c, but
For a large-diameter steel plate cell 2, a small block 1c whose size and shape are determined according to the diameter of the annular frame 1 is used as a small block 1a.
, 1b and are combined to form a large annular frame 1.

In addition, for a steel plate cell 2 with a small diameter, only the small block 1c is replaced, and the small blocks 1a and 1b are combined to form a small annular frame 1, which corresponds to the diameter of the steel plate cell 2. The size of the annular pedestal 1 can be formed as appropriate.

Furthermore, small adjustments to the diameter of the steel plate cell 2 can be made by moving the hydraulic chuck 3 along the elongated hole 22.

Reference numeral 12 shown in FIG. 1 is a hanging fitting for suspending the pouring device 11, which suspends the pouring device 11 by means of hanging wires 13, 13, . . . It is suspended from a crane hook 16 of a crane ship 15 by wires 14, 14, . . . .

In order to cast steel plate cells 2 using the pouring device 11 of the present invention configured as described above, first, the pouring device 11 is suspended from the crane hook 16 of the crane ship 15 via the hanging fitting 12. The integrated steel plate cell 2 is gripped by hydraulic chucks 3, 3, . The vibration generators 7, 7, etc. are operated at the same time, and the concrete is poured while checking the posture measurement and control.

In this case, the synchronized vibrations of the vibration generators 7, 7, . . . are transmitted to the hydraulic chucks 3, 3, . Since uniform vibration force is applied, the steel plate cells 2 can be cast in a well-balanced manner and rapidly.

In addition, regarding the dimensions of the steel plate cell 2, the size of the annular mount 1 is changed by combining the small blocks 1a, 1b of the annular mount 1 and several kinds of prepared blocks 1c as described above, and furthermore, By adjusting the above, steel plate cells 2 with different diameters can be cast using the same casting apparatus 11.

Therefore, if the steel plate cell driving device of the present invention is applied, the upper edge of the steel plate cell is held by a plurality of chucks arranged at equal intervals, and the supporting portion of the steel plate cell is placed through these chucks. , because they are placed by applying vibrating forces that are completely synchronized with each other, the large-diameter steel plate cells that have been constructed in advance can be placed in the same way as in the past, by excavating the place where they will be placed and backfilling them after being placed. Since it can be placed very easily and quickly without requiring a series of operations, it is less affected by the weather and has the effect of being able to be placed efficiently.

In addition, by applying the pouring device of the present invention, it is possible to form an annular pedestal that matches the outer diameter of the steel plate cell by combining the small blocks that make up the annular mount, so that the outer diameter of the steel plate cell can change. Since there is no need to prepare a plurality of pouring devices depending on the situation, there is also the effect that the cost of the pouring work can be reduced.

Furthermore, the number of vibration generators can be increased or decreased depending on the shape of the steel cell, soil quality, penetration length, etc., and the number of chucks can also be adjusted according to the shape and dimensions of the steel cell. Therefore, by using the pouring device of the present invention, it is possible to perform pouring suitable for the construction conditions with a single pouring device.

In particular, in the pouring device of the present invention, the dimensions of the annular pedestal can be increased or decreased according to changes in the dimensions of the steel plate cells, so the sizes of the annular member of the pouring device and the steel plate cells are balanced, and stable It has the advantage of being able to carry out pouring work.
