JPH0717820U - Wave-dissipating block - Google Patents

Abstract

(57) [Summary] [Purpose] A wave-dissipating block that is easy to manufacture, has strength, and can propagate plants. [Structure] Concrete was placed using a cloth bag having the same shape and dimensions as the production block as a formwork, and the cloth bag was made into a wave-dissipating block.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a block for a sea wall such as a harbor, a lake or a river (wave-dissipating block, root block, fishing reef block).

[0002]

[Prior art]

 Conventional revetment blocks are molded using a steel form or FRP form, and then the frame is removed to form a concrete block.

[0003]

[Problems to be solved by the device]

 Since a formwork is used, a lot of manpower is required for assembling, deframing and concrete placing work of this formwork, and in case of steel formwork, a crane car is required for the work. . Further, as shown in FIG. 2, the steel form frame has an assembly type block structure in which the bottom frame 11, the side frame 12, etc. are fixed by tightening bolts or cotter pins 13, so the form is unfolded when the block is manufactured. Therefore, the work area needs to be three times as large as the production block. Furthermore, since steel formwork cannot be folded below the size of the bottom and side frames, it requires a large area for storage or temporary storage, and also requires a large truck for transportation. .

Further, if it is made of steel, it is necessary to carry out surface cleaning and maintenance such as rust prevention.

Furthermore, the process of manufacturing the wave-dissipating block is one process including formwork assembly, concrete pouring, curing, and deframed, and since this process must be assembled according to the number of formwork, one day There is a limit to the amount of placement, and the work period will be long.

[0006]

[Means for Solving the Problems]

 Therefore, in the present invention, a cloth bag is manufactured in accordance with the shape and dimensions of the manufacturing block, the cloth bag is used as a mold, and concrete is placed therein, and the cloth bag is used as a wave-dissipating block. Therefore, the steps of assembling and deframing the mold are unnecessary, and the mechanical device therefor is also unnecessary.

[0007] Furthermore, the periphery of the cloth bag is tightened and strengthened with a cloth belt, and seeds of plants are put in the cloth belt so that the cloth bag can also function as a fishing reef.

[0008]

【Example】

 The present invention will be described below with reference to an embodiment shown in the drawings.

[0009] Fabric made of a cloth that passes through purified water but does not allow turbid water, cement or sand to pass, and that does not corrode with water, or synthetic fibers such as nylon. The cloth bag 1 according to the above is manufactured to form a mold, and concrete is placed inside the mold to manufacture a block. At the time of this production, the shape of the cloth bag cannot be determined unless concrete is poured to some extent. Therefore, it is advisable to place the bottom plate 2 on the bottom according to the bottom shape of the production block.

Further, in order to strengthen the cloth bag 1, it is preferable to tighten the peripheral surface with the cloth belt 3.

Further, it is preferable that the cloth belt 3 has a double structure so that plant seeds can be put in the cloth belt.

Then, this concrete is used as a wave-dissipating block together with the placed cloth bag.

[0013]

[Effect of device]

 According to the wave-dissipating block of the present invention, since one cloth bag is used for each block, the labor for assembling the formwork is unnecessary, and the cloth bag is used as a block even after the concrete is placed, so that it can be removed. No frame work is required. Furthermore, by using a cloth with good ventilation, the use of a vibrator when placing concrete can be omitted. Therefore, no labor is required, the number of workers is small, and the need for a large-sized crane truck is also small, so the production cost can be significantly reduced. The work area only needs to be the size of the bag itself, and storage, temporary storage and transportation can be done without any bulky work. Furthermore, because it is made of cloth, unlike the steel form, surface cleaning and rust prevention are unnecessary. As for the work process, the work of assembling the formwork and the work of removing the frame are not necessary, so the work period can be shortened significantly, and the number of castings per day can be greatly increased. Further, since the present invention is made of cloth, it has the following various effects that could not be considered in the conventional formwork.

[0014] First, since it is a cloth bag, it can be colored freely, so that it is possible to create a color feeling that matches the environment of the construction site such as a harbor, lake, river, etc., and this makes it possible to construct a concrete-exposed structure that is barely current. Instead of being as it is, it is possible to achieve harmony between artifacts and nature. In addition, the right and left sides of the harbor are color-coded in lighthouse colors to distinguish the routes of ships, to ensure navigation safety, and to display areas where ships, people, etc. are intruding and are restricted. Although it is possible to color the concrete block itself, this method not only deteriorates the strength of the concrete by adding a colorant, but also increases the material cost.

Since the block of the present invention has a structure in which the surface of a conventional concrete block is covered with a cloth, the impact strength against the objective becomes strong, and even if some creek occurs, it does not easily lose its shape. There is. The present invention further increases the strength by tightening with a cloth belt, and it can be expected to have a proliferative effect by planting plant seeds (seaweed, kelp, reeds), which was not possible with conventional blocks, As a result, a symbiotic effect with living things such as fish, abalone, turban shell, oyster, etc. is created, resulting in artificial reefs and breeding of living things, increasing water purification effect, activating water, and making it a human hydrophilic area It will have an action effect.
