Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial Application Field) The present invention relates to a decorative formwork for wave-dissipating blocks used for constructing breakwaters, sea walls, etc.

(Prior Art) Conventionally, tetrapods, which are wave-dissipating blocks, are manufactured using formwork in a factory, transported to an installation site, for example, a breakwater construction site, and stacked at a predetermined position using a crane. Also, on-site, we will promote the tetrapod using formwork.
There are also examples of buildings being constructed and installed using cranes.

<Problem to be solved by the invention> However, according to the conventional example of factory production, it is difficult to transport the completed tetrapods from the factory to the site.
Tetrapods are heavy and large, which not only increases labor and cost, but also makes the work dangerous. In addition, even if the product is produced on-site, assembly and disassembly of formwork is required.
It is necessary to transport the formwork again to the next construction site.

The purpose of this invention is to eliminate transportation problems and to enable wave-dissipating blocks to be installed easily and safely. (Means for Solving the Problems) A feature of the present invention is that the outer shape is formed into a plurality of legs 1a to 1a, i
It is formed in the shape of a wave-dissipating block with p, and has an oval shape with a decorative frame body 1 having a hollow interior. The decorative form body may be formed into an ellipse from the divided bodies 2 to 23, which are divided into a plurality of parts.
In this case, equal division may be used as the division method. Reinforcing ribs 5 and 6 may be formed on the inner surface of the decorative form body,
Furthermore, the frame 7 or 8 may be arranged within the decorative formwork.

(Example) Examples of the present invention will be described below. As shown in FIG. 1, the decorative formwork is a decorative formwork body 1 having a wave-dissipating block shape and a hollow interior, and has five legs 1a. 1b, lc, ld, le
have. The decorative form body 1 is made of cement, asbestos-free, cement/asbestos-free reinforced with glass fiber, synthetic resin, etc., and has a thin wall thickness. In this example, the decorative form body 1 is divided into three equal parts: a first, a second, and a
It consists of the third divided body 2, 3.4, and is divided into three equal parts with the axis X as a reference. In other words, the first divided body 2 shown in FIG.
, 1 dl, with an open top end, of which the legs 1a1 . 1dl is the lower half of legs 1a and 1d, and legs 1b1 and lcl are 1/1/2 of legs lb and lc.
It is divided into three parts. The second divided body 3 shown in FIG. 2(b) has four legs 1.
a2, 1b2. 1c2, 1e2, which is shaped like a container with an open bottom and back side, leg 1e2 is in an upright position, and among the legs, leg 1a2, 1e2 is half of leg 1a, le, respectively. So, leg part 1b2
, 1c2 are legs 1b and 1c divided into 1/3. Further, the third divided body 4 shown in FIG. 2(C) has four K parts l.
b3. 1c3. 1d2, 1e1, the lower side and the front side are open, and the leg 1e1 is in an upright state, and the legs 1d2, 1e are in an upright state.
1 is obtained by dividing the legs 1d and le into two parts, and the leg part 1b
3, 1c3 is obtained by dividing legs 1b, lc into 1/3. As shown in FIGS. 3 and 4, reinforcing ribs 5.6 are formed in the vertical and horizontal directions on the inner surface of the decorative form body 1, and each divided body 2--
We are trying to strengthen 4. A triangular columnar central frame 7 is located at the center of the decorative form body l, and square connecting frames 8, . . . are arranged at intervals within each divided body around this central frame. It has been done. As shown in FIG. 4, the center frame 7 is held in position by being engaged at engaging portions 9 where the legs 1a to 1d intersect. Further, the connecting frame 8 abuts against the side surface of the reinforcing rib 5, and the abutting portion is fixed with metal fittings such as separates. The connecting frames 8 have dimensions that gradually become smaller toward the center frame 7. Next, we will explain how to use it. For example, when constructing a breakwater, transport the divided bodies 2 to 4 to the vicinity of the breakwater construction position, place the first divided body 2 there, and then move the center frame 7 to the first divided body as shown in FIG. Then, the connecting frames 8 are arranged at intervals within each of the legs 1al to ldl, and both sides are fixed to the reinforcing ribs 5. After that, the second and third divided bodies 3.4 are placed over the first divided body 1, and the connecting frame 8 is connected and fixed to the reinforcing ribs 5 of each divided body 2, 3, thereby assembling the decorative frame body 1. Finish. Then, cement is injected from the injection port IO of the leg portion 1e to form a concrete wave-dissipating block.

Similarly, the decorative frame body 1 is assembled, wave-dissipating blocks are sequentially formed, and then transported to the installation site to construct the breakwater.

As another example of usage, on each wave-dissipating block consisting of a decorative formwork 1 with concrete poured inside, another decorative formwork is assembled, and several wave-dissipating blocks are stacked one on top of the other. It can be transported and constructed. The decorative frame body 1 is not necessarily limited to being divided into three parts, but each leg part 1a to 1d can be divided as shown in FIG.
It may be composed of the first to fifth divisions #11 to #15 and the central frame 7 located at the center. In this example, although not shown, a connecting means is provided at the abutting portions of the frame 7 and the opening ends of the divided bodies 11 to 15. 10 is an injection port. Further, the decorative form body 1 shown in FIG. 6 has four legs 1f.
, Ig, lh, 11, and this decorative form body is divided into three equal parts by a dividing line L shown by a chain line.
It consists of 6, 17, and 18. For example, as shown in FIG.
They are engaged by an arrow-shaped locking protrusion 16a and an engagement groove 17a. A concrete injection port 10 is provided on the end face of the leg 11. Depending on the size of the decorative formwork, workers may not be able to enter the interior, so it is possible to automatically connect the divided bodies or the divided bodies and the frame, as in the connecting means 16a and 17a in the sixth illustrated example. do. Another example of a ten-stage connection is shown in Figure 8. In the example of FIG. 8(a), an arrow-shaped engaging portion 16b. 17a, and a joint member 24 is engaged in the engaging portions 16b and 17a. As a connection method in this example, the joint member 24
One end of the groove 16b is connected in advance to the engagement groove 16b, and the engagement groove 17a is firmly fitted to the end of the groove from the direction of the arrow. In the example shown in FIG. 8(b), a gap is left between the abutting parts of the divided bodies 16 and l7, and the T-shaped joint member 25 is inserted into this gap from the direction of the arrow, and the hook parts 25a, 25a of the joint member 25 are inserted. It is hung on the dividing body 16 and 17. The shape of the decorative form body is not limited to the above example. For example, No. 9.
As shown in Figure 10, legs 1j, lk, lj, 1m. in. 1ρ
The decorative form body 1 is formed into a front cross-shaped decorative form body 1 having an axis x1.
Divide into 4 parts at the center and make divided bodies 19, 20, 21.22
It may also be oval.

As a method of dividing the decorative frame body 1 shown in FIG. 9, it may be divided into six parts as shown in FIG. Since the divided bodies 2 to 23 are divided into equal parts, they can be transported one on top of the other, which is convenient for transportation, but they do not necessarily need to be divided into equal parts. Although each of the above examples shows the case where the decorative form body is divided, it is not necessary to divide it. The frame 7.8 is selectively used depending on the shape of the decorative form body 1, etc., and is not always necessary.

As another example of the construction method, the breakwater etc. can be constructed immediately at the installation site by transporting the divided body directly to the breakwater construction site during low tide and pouring prefabricated concrete there.

(Effects of the Invention) As described above, according to the present invention, compared to the conventional method of transporting heavy wave-dissipating blocks and reusable formwork, the effort of transporting them can be saved, and the wave-dissipating blocks can be easily and safely transported. Can be installed. By applying an appropriate pattern to the decorative formwork, breakwaters, seawalls, etc. can be constructed without damaging the landscape.
