Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a casting device for large-diameter steel plate cells that have been made into an integral structure in advance.

When constructing seawalls, quay walls, bulwarks, 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 provide special measures to the steel plate cell.

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, it is necessary to prepare a plurality of steel sheet cell casting devices suitable for various diameters, which poses a problem in that the cost of the equipment increases.

Therefore, the present invention has been devised to solve the above-mentioned problems of the conventional art. The present invention aims to make it possible to extremely easily and rapidly drive steel plate cells by imparting vertical vibrations, and to make it possible to drive steel plate cells of various diameters with a single driving device. This is the purpose.

That is, the present invention arranges a required number of vibration generators on a frame in an annular manner at intervals almost similar to the upper part of the steel plate cell,

Note that reference numeral 12 shown in FIGS. 1 and 2 is a hanging fitting for suspending the driving device 11, and the hanging wire 13, 13 on the lower side thereof is
. . suspends the pouring device 11, and suspends the crane ship 15 by the upper hanging wires 14, 14, .
It is designed to be suspended from a crane hook 16.

In order to cast the steel plate cell 2 according to the present invention configured as described above, first, the casting device 11 is moved to the crane ship 15.
is suspended from a crane hook 16 via a hanging fitting 12, and the pre-integrated steel plate cell 2 is attached to a hydraulic chuck 3,
3..., and then towed to the pouring site by the crane ship 15, and simultaneously operate each vibration generator 7, 7... by operating the operation panel (not shown) on the generator ship 4. let me,
The concrete is poured while checking posture measurement and control.

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

Therefore, when pouring a large-diameter steel plate cell 2, vibration generators 7, 7..., universal joints 8, 8..., telescopic power shafts 9, 9..., shown by solid lines in FIG.・, bearing 10,
10... are arranged on the pedestal 1, and when pouring medium diameter steel plate cells 2, vibration generators T'7'... shown by broken lines are used.
Universal joints 8', 8'..., telescopic transmission shaft 9'9
'..., bearings 10', 10', etc. are arranged on the pedestal 1, and when a small diameter steel plate cell 2 is cast,
By reducing the number of interlocking devices such as the vibration generators 7, 7, etc., the vibration generators 7", 7", universal joints 8", 8", etc., and telescopic transmissions are shown by two-dot chain lines. Axis 9”, 9
By arranging the bearings 10'' and 10 on the frame 1, steel plate cells 2 with different diameters can be placed on the same pouring device 11.
can be poured.

In this case, the hydraulic chucks 3, 3, . . . are also moved and disposed appropriately in accordance with the arrangement of the interlocking devices such as the vibration generators 7, 7, etc. on the pedestal 1.

In addition, in this case, as shown in FIGS. 4, 5, and 6, the vibration generators 7, 7... and the bearings 10, 10... is moved in the direction of arrow A-A and fixed on the pedestal 1 with bolts 21A.

Therefore, if the steel plate cell driving device of the present invention is applied, the upper edge of the steel plate cell is clamped by a plurality of chucks at equal intervals, and the clamping portions of the steel plate cell are completely connected to each other through these chucks. Since the concrete is placed by applying a vibrating force synchronized with the concrete, it is not necessary to carry out a series of operations such as excavating the place where the pre-assembled large-diameter steel plate cell is to be placed, and backfilling it after being placed. It has the advantage that it can be placed very easily and rapidly without any need for it, is less affected by weather conditions, etc., and can be placed efficiently.

Further, according to the present invention, it is possible to cast steel plate cells with different diameters using the same pouring device, and there is no need to prepare multiple pouring devices depending on the diameter of the steel plate cells. This also has the effect of reducing construction costs.

In particular, in the present invention, steel plate cells of different diameters can be cast by simply moving the interlocking device such as the vibration generator radially without replacing the frame, preferably the polygonal annular frame. This method has the advantage that adjustments to the casting equipment due to changes in the dimensions of the steel plate cells can be made in a short time.
