[0001] The present invention relates to a covering part forming tool for forming a covering part covered by a part of a road surface on a part of the upper end of an embedded structure such as a side ditch, a formwork unit provided with the covering part forming tool, and a manufacturing method for manufacturing an embedded structure using the formwork unit.

Background Art

[0002] In an embedded structure such as a side ditch as shown in the conventional Patent Document 1, the upper end of the embedded structure was flush with the road surface. However, due to vehicles crossing, etc., it may deteriorate over time, and the upper end of the embedded structure may be damaged. Therefore, in recent embedded structures, a part of the upper end of the embedded structure is lowered by one step to form a covering part covered by a part of the road surface. The upper end of the embedded structure is covered with a paving material such as asphalt during road paving by this lowered covering part. Therefore, the upper end of the embedded structure is protected by the paving material and is less likely to be damaged. However, there was a problem that a dedicated formwork had to be prepared to form the covering part lowered by one step at the upper end of the embedded structure, increasing the manufacturing cost.

Embodiments for carrying out the invention

[0020] <Embodiment 1> Hereinafter, the covering part forming tool 500 according to Embodiment 1 of the present invention will be described with reference to FIGS. 1 to 3. Note that the shapes of the respective figures referred to in the following description are conceptual diagrams or schematic diagrams for explaining suitable shape dimensions, and the dimensional ratios etc. do not necessarily match the actual dimensional ratios. That is, the present invention is not limited to the dimensional ratios in the drawings.

[0021] First, FIG. 1 is an exploded perspective view of the covering part forming tool 500 of the present invention, FIG. 2 is an overall perspective view of the assembled covering part forming tool 500, FIG. 3(a) is a side view of the covering part forming tool 500, and FIG. 3(b) is a front view of the covering part forming tool 500. <00001​The covering part forming tool 500 comprises a base part 100 that is placed on a formwork described later, and an upper end surface forming part 400 that forms the upper end surface of the buried structure. The base part 100 is made of a metal square pipe and is elongated to match the length of the formwork of the buried structure. The bottom surface 110 of the base part 100 is the part that is placed on the formwork described later, and a magnetic part 111 made of a magnet may be provided on the surface of the bottom surface 110. The magnetic part 111 can be attracted to and fixed to the metal formwork described later by magnetic force. In addition to providing the magnetic part 111 on the bottom surface 110, the tool is not limited to this, and the entire base part 100 may be made magnetic (i.e., the entire metal base part 100 may be magnetized) so that it can be attracted to the formwork, and the entire base part 100 may be made into a magnetic part 111.

[0023] Furthermore, the upper end surface forming section 400 comprises a metal back plate 410 fixed to the fixing surface 120 of the base section 100, and a metal flat front plate 420, and includes an intermediate section 300 sandwiched between the back plate 410 and the front plate 420. The intermediate section 300 includes a metal connecting plate 310 that connects the back plate 410 and the front plate 420. As shown in Figure 3(b), the width of the connecting plate 310 is shorter than the width of the front plate 420 and the back plate 410, so grooves 320 are formed on both sides of the connecting plate 310, sandwiched above and below by the front plate 420 and the back plate 410. The leak prevention member 200 is fitted and fixed into these grooves 320. This leak prevention member 200 is made of an elastically deformable synthetic resin material such as rubber. The leak prevention member 200 is positioned on the end 401 side of the upper end surface forming portion 400, and the end 210 of the leak prevention member 200 protrudes laterally from the end 401 of the upper end surface forming portion 400. The upper end surface forming portion 400 is provided with leak prevention members 200 at both ends, but is not limited to this, and may be provided with a leak prevention member 200 at only one end.

[0024] The fixing surface 120 of the base portion 100 and the back plate 410 of the upper end surface forming portion 400 are fixed by welding, but are not limited to this, and may be fixed by any fixing means such as bolts and nuts. Also, the back plate 410 and the connecting plate 310, and the connecting plate 310 and the front plate 420 are fixed by welding, but are not limited to this, and may be fixed by any fixing means such as bolts and nuts. Furthermore, the fixing surface 120 of the base portion 100, and the back plate 410, connecting plate 310, and front plate 420 of the upper end surface forming portion 400 may be fixed together by through bolts.

[0025] Furthermore, although the base portion 100 and the back plate 410, connecting plate 310, and front plate 420 of the upper end surface forming portion 400 are made of metal, they are not limited to metal and can be made of any material such as wood. In addition, although the upper end surface forming portion 400 is equipped with a leak prevention member 200, it is not limited to this and may not be equipped with a leak prevention member 200 if there is no risk of concrete leakage.

[0026] Next, with reference to Figures 4 to 7, a method for manufacturing an embedded structure 900 using the covering part forming tool 500 of the present invention will be described. Figures 4 to 6 are front views showing the process of manufacturing an embedded structure 900 using a formwork 800. Figure 4 is a front view of the formwork 800, Figure 5(a) is a front view with the covering part forming tool 500 installed on the formwork 800, Figure 5(b) is an enlarged front view of the area around the covering part forming tool 500, Figure 6(a) is a front view of the formwork 800 with the covering part forming tool 500 installed and concrete poured in, Figure 6(b) is an enlarged front view of the area around the covering part forming tool 500, and Figure 7 is a front view of the manufactured embedded structure 900.

[0027] First, as shown in Figures 4 and 7, the formwork 800 is a conventional type and comprises a bottom wall 810 that forms the upper end 910 side of the buried structure 900, a side wall 820 that forms the side wall 920 side of the buried structure 900, and a central wall 830 that forms the drainage section 960 of the buried structure 900. At the lower end of the central wall 830, a stepped portion 831 is provided so that a cover-hanging portion 930 for placing a grating that closes the drainage section 960 can be formed. Furthermore, in order to integrally form a substantially L-shaped mounting plate 940 that is attached to the cover-hanging portion 930 with the upper end 910, the mounting plate 940 is positioned outside the stepped portion 831 of the central wall 830.

[0028] Then, by pouring concrete into the space X enclosed by the bottom wall 810, side walls 820, and central wall 830 of the formwork 800 and allowing it to solidify, an embedded structure such as a drainage ditch is manufactured. However, as shown in Figure 7, when forming a covering portion 950 on the upper end 910 of the embedded structure 900, the conventional formwork 800 cannot be used as is, and it is necessary to modify a part of the formwork 800, for example, by adding a step to a part of the lower end 821 of the side wall 820. Thus, because a part of the conventional formwork 800 has to be modified in order to form the covering portion 950 of the embedded structure 900, there was a problem that the manufacturing cost would increase accordingly. Furthermore, when changing the shape or size of the covering portion 950, it is necessary to modify a part of the conventional formwork 800 each time, which also increases the manufacturing cost.

[0029] Therefore, in the present invention, without making any changes to the conventional formwork 800, it is possible to manufacture an embedded structure 900 equipped with a covering portion 950 by using the conventional formwork 800 as is. Specifically, as shown in Figure 5, the covering portion forming tool 500 is installed on the bottom wall 810 of the conventional formwork 800. A magnetic part 111 is provided on the bottom surface 110 of the base portion 100 of the covering portion forming tool 500, so that the magnetic part 111 is fixed to the bottom wall 810 by magnetic force, making installation easy. In addition, the upper end surface forming portion 400 is positioned so as to be sandwiched between the side wall 820 and the mounting plate 940. Each of the ends 401 of the upper end surface forming portion 400 is in contact with either the side wall 820 or the mounting plate 940. Furthermore, each of the ends 210 of the leak prevention member 200 is also in contact with either the side wall 820 or the mounting plate 940.

[0030] Next, as shown in Figure 6, concrete C is poured into space X in the same manner as in the conventional method. After the concrete C has hardened, the buried structure 900 is removed from the formwork 800 and inverted, completing the buried structure 900 shown in Figure 7. Since concrete C does not flow into the area where the covering part forming tool 500 is installed, the space created by this covering part forming tool 500 becomes the covering part 950 of the buried structure 900. The upper end surface forming part 400 of the covering part forming tool 500 forms the surface 951 of the covering part 950 of the buried structure 900.

[0031] As shown in Figure 7, the covering portion 950 has a shape that is recessed below the tip of the mounting plate 940, and the depth D1 of the covering portion 950 corresponds to the height H1 of the covering portion forming tool 500. Thus, with the covering portion forming tool 500 of the present invention, the covering portion 950 of the buried structure 900 can be formed by using the conventional formwork 800 as is, thereby reducing manufacturing costs. Furthermore, even if it is desired to change the shape of the covering portion 950, such as the depth D1, this can be done by replacing the covering portion forming tool 500, so the conventional formwork 800 can be used as is, thus reducing manufacturing costs. In addition, with the formwork unit equipped with the covering portion forming tool 500 and formwork 800 of the present invention, the conventional formwork 800 can be used as is, thus reducing manufacturing costs.

[0032] Furthermore, as shown in Figure 6(b), each of the ends 401 of the upper end surface forming section 400 abuts against the side wall 820 or the mounting plate 940. As a result, concrete C is less likely to flow downward from the upper end surface forming section 400, and the covering section 950 of the buried structure 900 is neatly formed. In addition, each of the ends 210 of the leak prevention member 200 also abuts against the side wall 820 or the mounting plate 940, so concrete C does not flow downward from the upper end surface forming section 400, and the covering section 950 of the buried structure 900 is neatly formed. In particular, the ends 210 of the leak prevention member 200, which are made of an elastically deformable material such as rubber, protrude laterally from the ends 401 of the upper end surface forming section 400. As a result, the ends 210 of the leak prevention member 200 are elastically deformed and pressed against the side wall 820 or the mounting plate 940. As a result, the end portion 210 of the leak prevention member 200 adheres tightly to the side wall 820 or the mounting plate 940, more reliably preventing the concrete C from flowing downwards.

[0033] Then, as shown in Figure 8, when installing the buried structure 900 at the actual site, the buried structure 900 is embedded in the road surface G. Figure 8 is a front view of the road surface G in which the buried structure 900 is embedded. As shown in Figure 8, the road surface G is paved with paving material such as asphalt so that the tip of the mounting plate 940 of the buried structure 900 is at the same height as the road surface G. At that time, the surface 951 of the covering portion 950, which is recessed one level below the tip of the mounting plate 940 of the buried structure 900, will be covered with the paving material. In addition, since the tip of the mounting plate 940 protrudes above the surface 951 of the covering portion 950, the paving material such as asphalt will not flow into the drainage portion 960. In this way, the upper end 910 side of the buried structure 900 is covered with the paving material of the road surface G, making it less susceptible to damage. The upper part of the drainage section 960 is closed by a cover member such as a grating, which is installed so as to span across the mounting plates 940 on both sides.

[0034] In the formwork unit of the present invention shown in Figure 6, the covering part forming tool 500 is installed in a location surrounded by the bottom wall 810, the side wall 820, and the mounting plate 940. However, it is not limited to this, and if the buried structure 900 does not have a mounting plate 940, the covering part forming tool 500 may be installed in a location surrounded by the bottom wall 810, the side wall 820, and the stepped portion 831 of the central wall 830. Also, although the buried structure 900 is in the form of a U-shaped drainage ditch, it is not limited to this, and may be in any form such as a water collection basin.

[0035] <Embodiment 2> The following describes the coating forming tool 500A according to Embodiment 2 of the present invention. Note that the coating forming tool 500A according to Embodiment 2 differs only in the configuration of the base portion 100A; the other configurations are the same as the coating forming tool 500 according to Embodiment 1, so a detailed explanation of the common configurations will be omitted. Figure 9 is a front view of the coating forming tool 500A.

[0036] The base portion 100A of the covering portion forming tool 500A is equipped with an expandable portion 170A consisting of a bolt portion 150A and a nut portion 160A. The head 151A of the bolt portion 150A is the part that is installed on the bottom wall of the formwork, and the tip 152A is screwed into the hole 161A of the nut portion 160A. The nut portion 160A is fixed to the upper end surface forming portion 400A. By rotating the bolt portion 150A relative to the nut portion 160A, the height H1A of the base portion 100A can be arbitrarily changed. By changing the height H1A of the base portion 100A, the height of the upper end surface forming portion 400A can also be changed. As a result, the depth D1 of the covering portion formed by the covering portion forming tool 500A can also be changed as appropriate. The telescopic section 170A is composed of a bolt section 150A and a nut section 160A, but is not limited to this configuration. Any configuration can be adopted as long as it can be extended and retracted to change the height H1A.

[0037] Furthermore, the covering part forming tool, the formwork unit equipped with the covering part forming tool, and the manufacturing method for manufacturing an embedded structure using the formwork unit of the present invention are not limited to the above embodiments, and various modifications and combinations are possible within the scope of the claims and embodiments, and these modifications and combinations are also included in the scope of the patent rights.
