Description

  TECHNICAL FIELD The present invention relates to a wave-dissipating block mold apparatus, and more particularly to a wave-dissipating block mold apparatus capable of manufacturing two types of wave-dissipating blocks having different shapes.

  A large number of wave-dissipating blocks are stacked and installed on existing supporting base blocks, for example, in harbors, coastal breakwaters, seawall extinguishing works, jetty works, breakwater works, and anchor works. As a conventional wave-dissipating block, for example, a rod-shaped or V-shaped leg portion projecting in a plurality of radial directions on a side surface of a body portion (main body central portion) having a square cross section is known.

A conventional example of this type of wave-dissipating block is shown in FIG . The wave-dissipating block 1 has three (or two) leg portions 3, 3, and 3 projecting radially at the upper end of a body portion 2 having a hexagonal cross section, and the lower end of the body portion 2. leg 4,4,4 of three (or two) is projected in the radial direction in part. And the upper end side leg parts 3, 3, and 3 are arrange | positioned facing the lower end side leg parts 4, 4, and 4 (same phase) (for example, refer patent document 1, 2).

On the other hand, the present applicant has developed a different-phase wave-dissipating block having a three-dimensional shape different from the conventional in-phase wave-dissipating block 1 and has already filed a patent application on April 10, 2008. . As shown in FIG. 34 , the wave-dissipating block 5 has upper end legs 6, 6, 6 having a phase difference of 60 degrees with respect to the lower end legs 7, 7, 7 in the outer peripheral direction of the body part 2. And the wave-dissipating performance can be significantly improved by accumulating the wave-dissipating block 5 on the said basic block (refer patent document 3).

  The wave-dissipating block is manufactured by placing concrete in a formwork apparatus having a space corresponding to the three-dimensional shape of the wave-dissipating block. In this case, since the three-dimensional shape is different between the conventional in-phase type wave-dissipating block and the different-phase type wave-dissipating block, when manufacturing the in-phase type wave-dissipating block or the different-phase type wave-dissipating block, It is necessary to use a dedicated formwork device.

  Therefore, in order to manufacture the in-phase type wave-dissipating block and the different-phase type wave-dissipating block, it is necessary to prepare two types of mold apparatus, so that the manufacturing cost of the mold apparatus becomes expensive and economical. There was a problem that it was disadvantageous.

  In order to solve the above problem, it is conceivable to form the mold apparatus in a split structure that can be recombined to accommodate two types of wave-dissipating blocks. However, in this case, if the draft of the formwork device after the recombination is in the opposite direction, it becomes difficult to release the mold after placing the concrete. For this reason, it is necessary to configure so that the draft after recombination does not reverse in the development of the divided formwork apparatus.

  Therefore, a technical solution to be solved in order to provide an inexpensive formwork apparatus that can be shared when manufacturing two types of wave-dissipating blocks having different three-dimensional shapes, and that can easily perform a releasing work after recombination. A problem arises, and the present invention aims to solve the problem.

This invention has been proposed in order to achieve the pre-Symbol object, an invention according to claim 1 wherein each upper and lower ends of the body, of 120 degrees from each other as viewed in the axial direction of the barrel body In a mold apparatus used when manufacturing a wave-dissipating block having three legs projecting at an angle, the mold apparatus has a bottom surface mold having a planar shape corresponding to the bottom surface of the wave-dissipating block. A pair of upper divided bodies each having a three-dimensional shape corresponding to the outer peripheral side surface of the wave-dissipating block and divided into six equal parts in the circumferential direction. and there is provided a lower split body and the wave dissipating blocks for formwork device being formed integrally.

  According to this configuration, it is possible to manufacture both in-phase type and out-of-phase wave-dissipating blocks by recombining and using one formwork device. For example, when manufacturing an in-phase type wave-dissipating block after manufacturing the in-phase type wave-dissipating block, the upper divided bodies of the adjacent side surface molds are recombined with each other to assemble the mold apparatus. Thus, a three-dimensional formwork apparatus corresponding to the out-of-phase wave-dissipating block is completed. Thereafter, when the in-phase type wave-dissipating block is manufactured, the upper divided body may be returned to the original state and assembled.

The invention according to claim 2 manufactures a wave-dissipating block in which three leg portions projecting from each other at an angle of 120 degrees as viewed in the axial direction of the body portion are provided on the upper end portion and the lower end portion of the body portion. In the formwork device used at the time,
The mold apparatus includes a bottom mold having a planar shape corresponding to the bottom surface of the wave-dissipating block, and a pair of upper portions having a three-dimensional shape corresponding to the outer peripheral side surface of the wave-dissipating block and separable in the vertical direction. It consists of a side mold and a lower side mold, and the upper side mold and the lower side mold are each divided into three equal parts in the circumferential direction , and the trunk section of the body part is a regular hexagon. in conjunction is formed, to provide the upper side mold and the wave dissipating blocks for formwork device stepped Ru without smoothing Dare the lower side mold to the shaft portion after the manufacturing recombined.

  According to this configuration, it is possible to manufacture both in-phase type and out-of-phase wave-dissipating blocks by recombining and using one formwork device. For example, when manufacturing an in-phase wave-dissipating block after manufacturing an in-phase wave-dissipating block, after separating the upper side mold from the lower side mold, the upper side mold is rotated around the central axis. A three-dimensional formwork device corresponding to the out-of-phase wave-dissipating block is completed by reversing it by 60 degrees and recombining it with the lower side formwork. Thereafter, when the in-phase type wave-dissipating block is manufactured, the upper side surface formwork may be returned to the original state and assembled.

In the invention according to claim 1 , the mold apparatus has a bottom surface mold form having a planar shape corresponding to the bottom surface of the wave-dissipating block, a three-dimensional shape corresponding to the outer peripheral side surface of the wave-dissipating block, and consists of a 6 equally divided side mold in a direction, each side mold is formed by integrating the recombinant possible pair of top part and a lower split body together, each side mold adjacent By recombining the upper divisions with each other, two types of wave-dissipating blocks with different three-dimensional shapes can be manufactured, so there is no need to manufacture two dedicated formwork devices as in the conventional example, and the production cost of the formwork device Can be halved.

Further, since the drafting apparatus after the recombination does not have the reverse draft, the mold release operation after placing the concrete can be easily performed. That is, the mold apparatus after the recombination can easily perform the mold release work after placing the concrete through ensuring the required draft angle.

The invention according to claim 2 can manufacture both in-phase type and out-of-phase type wave-dissipating blocks by recombining one formwork device. That is, when manufacturing a wave-dissipating block with three legs projecting, the present invention reconstructs a three-dimensional structure by revolving the upper side formwork around the central axis by rotating it 60 degrees and recombining it with the lower side formwork. Since two types of wave-dissipating blocks having different shapes can be manufactured, the same effect as that of the first aspect of the invention, that is, the production cost of the formwork apparatus can be halved, and the mold release work after placing the concrete is easy It can be carried out.

  In order to achieve the object of the present invention, it is possible to inexpensively manufacture a separable formwork apparatus that can be shared by two types of wave-dissipating blocks and that can be easily separated after recombination. It is used when manufacturing a wave-dissipating block in which three leg portions projecting from each other at an angle of 120 degrees in the axial direction view (plan view) of the body portion are respectively provided at the upper end portion and the lower end portion of the body portion. In this mold apparatus, the mold apparatus has a bottom surface mold form having a planar shape corresponding to the bottom surface of the wave-dissipating block, a solid shape corresponding to the outer peripheral side surface of the wave-dissipating block, and a circumferential direction. Each side mold was realized by integrally forming a pair of upper and lower divided bodies that can be recombined with each other.

  A preferred embodiment of the present invention will be described below with reference to FIGS. 1 and 2 show two types of wave-dissipating blocks 10 and 20 manufactured by the formwork apparatus of the present invention. As shown in FIG. 1, the wave-dissipating block 10 of a different phase type includes a rod-shaped body portion 11, and the body section 11 is formed in a regular hexagonal cross section. Three leg portions 12, 13, and 14 project radially from the outer peripheral side surface of the upper end portion of the body portion 11, and the leg portions 12, 13, and 14 are viewed in a plan view (viewed in the vertical axis direction of the body portion 11). They are at an angle of 120 degrees to each other.

  In addition, three leg portions 15, 16, and 17 project radially from the outer peripheral side surface of the lower end portion of the body portion 11, and the leg portions 15, 16, and 17 form an angle of 120 degrees with each other in plan view. ing. Furthermore, the leg portions 15, 16, and 17 on the lower end side have a phase difference of 60 degrees with respect to the leg portions 12, 13, and 14 on the upper end side.

  Each of the six leg portions 12 to 17 is gradually reduced in diameter from the root portion toward the tip portion, and each leg portion 12 to 17 is formed in a square cross section. Moreover, the width dimension of the base part of the six leg parts 12-17 corresponds with the width dimension of the trunk | drum 11 side surface. Note that the three-dimensional shape of the in-phase type wave-dissipating block 20 shown in FIG. 2 is such that the leg portions 15, 16, 17 on the lower end side and the leg portions 12, 13, 14 on the upper end side face each other (the phase is the same). Is the same as the wave-dissipating block 10 of the different phase type, except that it is located at.

  Next, a steel plate formwork apparatus according to the present invention will be described. As shown in FIGS. 3 and 4, the mold apparatus 18 includes a single bottom plate mold 19 and six side plate molds 21 to 26. The bottom plate mold 19 has a planar shape corresponding to the bottom shape of the wave-dissipating blocks 10 and 20. The six side plate molds 21 to 26 have a three-dimensional shape corresponding to the side shape of the outer periphery of the wave-dissipating blocks 10 and 20.

  The side plate molds 21 to 26 of the present embodiment are divided in the vertical direction, but have an equal interval of 60 degrees in plan view. Therefore, the six side plate molds 21 to 26 are erected on the outer periphery of the bottom plate mold 19, thereby forming a space (concrete filling portion) corresponding to the three-dimensional shape of the wave-dissipating blocks 10 and 20.

  Each of the side plate molds 21 to 26 includes a pair of upper and lower divided bodies, that is, an upper divided body 211 to 261 and a lower divided body 212 to 262. A pair of upper and lower divided bodies 211 to 261 and lower divided bodies 212 to 262 are recombined with each other by fastening and integrating them with bolts and nuts (not shown; hereinafter referred to as “fasteners”). Possible side plate molds 21 to 26 are formed. For this reason, the upper divided bodies 211 to 261 and the lower divided bodies 212 to 262 of the side plate molds 21 to 26 can be separated or coupled to each other via the fasteners.

  After separation, the three-dimensional shape of the formwork device 18 is changed by recombining the adjacent upper divided bodies 211 to 261 to form the three-dimensional shape of the in-phase type formwork device 28 (see FIG. 5). Is done.

  The six side plate molds 21 to 26 are arranged in this order in the counterclockwise direction along the outer peripheral direction of the bottom plate mold 19 in FIG. The side plate molds 21 to 26 have the same three-dimensional shape as a whole, but the side plate molds 21 and 24, the side plate molds 22 and 25, and the side plate molds 23 and 26 are mutually connected. Can be assembled upside down.

  Furthermore, the three-dimensional shape of the upper divided bodies 211 to 261 or the lower divided bodies 212 to 262 is classified into either a left and right wing-shaped projecting type or a bent piece extending type. Those belonging to the left and right wing-shaped single protrusion type are upper divided bodies 211, 231, 251 and lower divided bodies 222, 242, 262. Also, those belonging to the bent piece extending type are the lower divided bodies 212, 232, 252 and the upper divided bodies 221, 241, 261.

  Here, the upper divided body 211 which is a left and right wing-shaped single-projection type is a vertically long rectangular plate having a left and right width corresponding to the side surface of the body portion 11 and a wing shape horizontally projecting on the left and right sides of the upper end portion of the rectangular plate. The wing piece has a shape corresponding to the side surfaces of the leg portions 12 to 17 of the wave-dissipating blocks 10 and 20.

The bent piece has a shape corresponding to the upper surface and the distal end surface of each of the leg portions 12 to 17 of the wave-dissipating blocks 10 and 20.

  Next, a procedure for assembling the different phase type mold apparatus 18 using the bottom plate mold 19 and the side plate molds 21 to 26 will be described. The side plate molds 21 to 26 are integrated by fastening a pair of upper and lower divided bodies 211 to 261 and lower divided bodies 212 to 262 with fasteners.

  Further, when assembling the mold apparatus 18, the bottom plate mold 19 and the side plate molds 21 to 26 are arranged with the inner surface facing upward, and after removing concrete debris and the like adhering to the inner surface by cleansing and cleaning, It is assumed that a concrete release material is applied to the inner surface in advance.

  First, the bottom plate molds 19 are arranged in a horizontal plane so as not to be inclined, and the side plate molds 21 to 26 are arranged and assembled on the bottom plate molds 19. In this case, the assembly order of the side plate molds 21 to 26 is arbitrary. It is. As shown in FIG. 6, for example, the side plate mold 24 is set at a predetermined position on the outer periphery of the bottom plate mold 19, and the side plate mold 24 is temporarily fastened to the bottom plate mold 19 with a fastener.

  Subsequently, as shown in FIG. 7, a side plate mold 23 is erected on one side of the side plate mold 24 in a contact state, and the side plate mold 23 is attached to the bottom plate mold 19 and the side plate mold 24 with a fastener. Tighten temporarily. After that, as shown in FIG. 8, the side plate mold frame 25 is disposed on the other side of the side plate mold frame 24 in an abutting state, and the side plate mold frame 25 is fastened to the bottom plate mold frame 19 and the side plate mold frame 24. Tighten with tools. Thereafter, a core rebar (not shown) is installed at a predetermined position in the mold.

  Thereafter, the remaining side plate molds 26, 22, and 21 are sequentially assembled onto the bottom plate mold 19 and temporarily tightened in the same manner as described above. Then, when all of the side plate molds 21 to 26 have been temporarily tightened, the fasteners are finally tightened and connected to complete the assembly of the mold apparatus 18 having the upper surface opening as shown in FIG. To do.

  Next, the case where the wave-dissipating block 10 is manufactured using the mold apparatus 18 will be described. First, as shown in FIG. 10, concrete 30 is poured from the upper surface opening of the mold apparatus 18, and the concrete 30 is squeezed while being compacted sequentially from the lower space portion to the upper space section in the mold apparatus 18. I will set it up. Then, as shown in FIG. 11, when the concrete 30 is placed up to the upper surface of the formwork apparatus 18, the upper surface of the concrete 30 is smoothed and finished with a trowel.

  Thereafter, as shown in FIG. 12, the top end surface of the mold apparatus 18 is covered with the water spray sheet 31, and the concrete 30 is cured for a required time until the hardening strength of the concrete 30 reaches a predetermined value. And when the required time passes and the hardening strength of the concrete 30 reaches a predetermined value, the water spray sheet 31 is removed from the mold apparatus 18 as shown in FIG.

  When the water spray sheet 31 is removed, the side plate molds 21 to 26 are released from the concrete 30 as shown in FIG. In this case, as shown in FIG. 15, the side plate molds 21 to 26 can be easily removed because they move smoothly away from each other in the radial direction of the concrete 30.

  Then, as shown in FIG. 16, all the side plate molds 21 to 26 are released. When the mold release work of the side plate molds 21 to 26 is completed, as shown in FIG. 17, a wire 32 is hung on the top of the hardened concrete 30 and suspended by a crane or the like, and then, as shown in FIG. The concrete 30 is moved above the frame 19.

  After releasing the bottom plate formwork 19 from the concrete 30 in this way, the concrete 30 is then moved to the product place, thereby producing the wave-dissipating block 10 of the different phase type shown in FIG.

  Hereinafter, the same manufacturing process as described above, that is, after applying the concrete release material to the bottom plate mold 19 and the side plate molds 21 to 26, the side plate molds 21 to 26 are set on the bottom plate mold 19 and temporarily fixed. At the same time, a guard rebar is installed at a predetermined position. Thereafter, the wave-dissipating block 10 is newly manufactured through concrete placement, curing, and mold release operations.

  Next, a procedure for assembling the in-phase type mold apparatus 28 shown in FIG. 5 using the bottom plate mold 19 and the side plate molds 21 to 26 will be described. In this case, the side plate molds 21 to 26 are recombined so as to have a three-dimensional shape shown in FIG.

When assembling the device 28, as shown in FIG. 21, the fastener is loosened, and the left and right wing-shaped projecting type upper divided body 211 and the bent piece extending type upper divided body 221 are removed.

  Then, as shown in FIG. 22, the left and right wing-shaped projecting type upper divided body 211 is fastened and fixed to the left and right wing-shaped projecting type lower divided body 222 and the bent piece extending type upper divided body 221 is bent. Fastened and fixed to the lower divided body 212 of the single extension type. Thus, the side plate molds 22A and 21A shown in FIG. 19 are formed. Then, side plate molds 23A to 26A are formed by recombination in the same manner as described above.

  Next, when assembling the side plate molds 21A to 26A at predetermined positions on the bottom plate mold 19, they can be assembled according to the same procedure as described above. That is, after the concrete release material is applied to the inner surfaces of the bottom plate mold 19 and the side plate molds 21A to 26A, the side plate molds 21A to 26A are sequentially assembled on the horizontally installed bottom plate mold 19 and temporarily tightened with fasteners. A bounce rebar is also installed. Thereafter, when all of the side plate molds 21A to 26A are temporarily tightened, the fasteners are finally tightened to complete the assembly of the in-phase type mold apparatus 28 shown in FIG.

  When the in-phase type wave-dissipating block 20 is manufactured using the formwork device 28, the steps shown in FIGS. 10 to 18, that is, concrete placement, curing, side plate formwork, and bottom plate formwork, are performed. The in-phase type wave-dissipating block 20 is manufactured through the steps of demolding.

  The same phase type mold apparatus 28 according to the present invention can be easily recombined from the different phase type mold apparatus 18 shown in FIG. In this case, an upper connecting body 33 in which the upper divided bodies 211 to 261 are connected to each other and a lower connecting body 34 in which the lower divided bodies 212 to 262 are connected to each other are used.

  That is, as shown in FIG. 23, the fastener is loosened and separated into the upper connector 33 and the lower connector 34. Thereafter, the upper connecting body 33 is rotated about the central axis C by 60 degrees, so that the rotational position of the upper connecting body 33 is displaced by 60 degrees with respect to the lower connecting body 34.

  Then, the upper connecting body 33 is lowered to the lower connecting body 34 side, the lower end portion of the upper connecting body 33 is joined to the upper end portion of the lower connecting body 34, and the joined portion is fastened with a fastener. Thereby, the upper coupling body 33 and the lower coupling body 34 are integrated and recombined into the same phase type mold apparatus 28.

The lower side surface formwork 40 has a three-dimensional shape corresponding to the lower side surfaces of the wave-dissipating blocks 10 and 20, and is formed by integrating three lower divided bodies 44, 45, and 46 that can be divided from each other.

  Further, the upper divided bodies 41, 42, 43 and the lower divided bodies 44, 45, 46 are formed at equal intervals in the circumferential direction. The upper divided bodies 41, 42, 43 and the lower divided bodies 44, 45, 46 have the same three-dimensional shape as a whole, but are set upside down when used.

  The upper divided bodies 41, 42, and 43 protrude from the left and right sides of the upper portion of the vertical portion and the vertical portion having a substantially U-shaped cross section corresponding to the upper half of the body portion 11 of the wave-dissipating blocks 10 and 20, respectively. It consists of a horizontal wing-like part, and the three-dimensional shape of the horizontal wing-like part corresponds to the upper end side leg part of the wave-dissipating blocks 10 and 20.

  Further, the lower divided bodies 44, 45, and 46 project from a vertical portion having a substantially U-shaped cross section corresponding to the lower half portion of the body portion 11 of the wave-dissipating blocks 10 and 20, and to the left and right sides of the lower end portion of the vertical portion. The three-dimensional shape of the horizontal wing-shaped portion corresponds to the upper leg portion of the wave-dissipating blocks 10 and 20.

  Next, a procedure for assembling the different phase type mold apparatus 18 using the bottom plate mold 38, the upper side mold 39, and the lower side mold 40 will be described. First, after applying a concrete release material to the inner surfaces of the bottom plate mold 38, the upper side mold 39 and the lower side mold 40, the bottom plate mold 38 is arranged in a horizontal plane so as not to be inclined, as shown in FIG.
