Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a formwork for a multipurpose block which can be used as a wave breaking block, a fish reef block or the like.

Usually, this type of block body is constructed of unreinforced concrete and weighs about 1 to 30 tons. Among these blocks, those that are bulky and heavy are mainly concrete-molded at the construction site from the viewpoint of transportation.

For this purpose, a molding form that can be installed on-site is required. In other words, formwork that can be installed on site is
It is a disassembled type that does not take up much space during transportation, and since it is an on-site operation, it must be easy to assemble.

Therefore, a first object of the present invention is to obtain a formwork that is easy to disassemble and assemble and has excellent transportability.

Another object of the present invention is to obtain a formwork that can commonly construct blocks of several shapes ranging from an eight-legged wave-dissipating block to a four-legged upright block or an inverted block. It is.

A further feature of the invention is that the formwork for this type of block is relatively simple to manufacture and consists of a geometric structure that can be processed uniformly.

To this end, in the present invention, the formwork of the pillar extends in the direction of the diagonal line connecting the opposing vertices of the cube, the frame edge corresponding to the edge connecting the vertices other than these two apexes, and the formwork and the frame edge. It consists of a polygonal frame with a series of polygonal frames, and the half-cut portions of these parts are integrally constructed.

Hereinafter, the features of the formwork of the present invention will be explained in further detail with reference to the illustrated embodiments.

Figures 1 to 3 are principle diagrams showing the design concept of the formwork of the present invention, and Figure 1 shows a diagonal line L connecting one vertex A of an imaginary cube 1 and its opposite vertex B.
The formwork 3 of the pedestal 2 whose central axis is the extension line L' of is shown. In addition, this pedestal 2 has a cylindrical-conical shape that becomes smaller in diameter toward the tip, taking into account the strength problem of unreinforced concrete and the interlocking of the legs when the completed blocks are piled up randomly. configured and valid.

FIG. 2 shows the vertex A in the virtual cube 1.
A state in which the edge portion connecting six vertices C other than B and B is used as the frame edge 4 is shown.

FIG. 3 shows a polygonal frame 5 that is connected to the circular base of the formwork 3 and the frame edge 4. Although this polygonal frame 5 is a hexagonal body connecting the circumference and the square, it may have a configuration of more polygons or a configuration close to a spherical surface.

FIG. 4 is a perspective view showing an embodiment of the formwork of the present invention constructed based on the above-mentioned design concept, in which the frame edges 4 and the formwork 4 of the pillar 2 serve as the joint ends of the formworks.
An angle member 6 that stands upright to the half-cut edge of the polygonal frame 5 is welded to the half-cut edge of the polygonal frame 5. Bolt holes 7 are sequentially drilled in this angle material 6 at appropriate intervals, and when the formwork is assembled, the bolt holes 7 are drilled into the angle material 6 when the formwork is in contact with the angle material 6.
It is integrated by tightening the bolt material passed through.

FIG. 5 is a plan view of the eight-legged block assembled as a block formwork, and FIG. 6 is a partially cutaway side view thereof.

Here, as can be understood from the assembly diagrams shown in FIGS. 5 and 6, the formwork for the standing block constructed by the formwork of the present invention is a frame between the half-cut formworks. The edges 4, and more specifically the joints of the angle members 6 in this area, are all arranged in a straight line throughout the assembly of the octapod block.
This means that even at the junction of this linear array,
This means that the entire block can be divided into shapes.
That is, for example, in the side view of the eight-legged block shown in Figure 6, the upper four-legged block and the lower four-legged block can be separated at the horizontal line joint in the center, and a flat plate, etc. By placing and molding it, a four-legged block can be easily constructed.

While the eight-legged block is effective as a wave-dissipating block, the four-legged block constructed in this way can be used as a fish reef block by placing the four legs facing downward, and can be used as a fish reef block by placing the four legs facing upward. It can also be used as a growth block for algae.

As described above, the formwork of the present invention useful as a formwork for an eight-legged or four-legged block, when assembled and used, can be used as a formwork for an eight-legged block, such as the upper surface mold and the lower surface mold, that is, the portions shown in the fifth plan view. Since the mold can be cut out with the four basic formworks assembled together, the horizontally positioned formwork can be cut out based on the integrated part that opens in all directions during mold-setting and die-cutting work. Since the parts can be assembled or removed in sequence, the work is easy.

In addition, when transporting or storing the formwork, all the formwork, including the four integrated formworks mentioned above, can be disassembled, so you can stack the disassembled individual formworks, etc. It can be packed into a small volume, making it extremely convenient and extremely effective in reducing transportation and storage costs.

Furthermore, the formwork of the present invention has advantages in processing, such as when processing two split molds constituting one pillar 2, only one common original mold is required for processing the molds. It also has sex.

As described above, the formwork of the present invention can be used as a formwork for an eight-legged block by using a half-split mold as the basic formwork for constructing an integral leg pillar, and by combining these forms. It is possible to freely configure it for four-legged blocks, and when using the formwork, it is possible to assemble other basic formworks as well as to integrate the four pieces of the basic formwork with legs spread in four directions. It can be removed and the work is easy, and when transporting or storing the formwork, the entire formwork can be disassembled into basic formworks and these can be stacked, reducing costs due to the small bulk.Furthermore, During formwork processing, the formwork of the present invention is extremely effective in practice as a formwork for this type of block, as there are many parts with the same or symmetrical shape between the formworks, so it can be made with a small number of processing dies. It is what it is.
