[0019] Hereinafter, a barricade 10 according to an embodiment of this disclosure will be described with reference to Figures 1 to 11. Figure 1 shows a pair of barricades 10 arranged side by side with their front and back sides facing opposite directions in the thickness direction. Hereinafter, the thickness direction of the barricade 10 will be referred to as the "front-to-back direction H1," and the horizontal direction perpendicular to the front-to-back direction H1 will be referred to as the "lateral direction H2." Although the barricade 10 does not have a front or back distinction, for the purpose of explaining the structure of each part, one side in the front-to-back direction H1 will be referred to as the "front side," and the other side as the "rear side."

[0020] As shown in Figure 1, the barricade 10 can be distinguished from bottom to top into a base section 11, a lower section 12, an intermediate section 13, and an upper section 14. The lower section 12 has a pair of slopes 12S in the front and back, and these slopes 12S are inclined to move away from each other as they extend downwards.

[0021] The intermediate section 13 is a roughly rectangular parallelepiped that is flattened horizontally in the front-to-back direction H1, and has a pair of vertical main planes 13S that rise upward from the upper ends of a pair of inclined surfaces 12S of the lower section 12. The sides 12T and 13T located at both ends of the lower section 12 and the intermediate section 13 in the horizontal direction H2 are continuous flat surfaces flush with each other. Decorative recessed sections 23 are formed on each of the two main planes 13S of the intermediate section 13. In this embodiment, the decorative recessed sections 23 are, for example, in the shape of the symbol ">", and one pair is provided side by side on each of the two main planes 13S. Furthermore, the orientation of the ">" of the decorative recessed sections 23 is reversed between the pair of main planes 13S. Note that reflective stickers or the like may be attached to the bottom surface of the decorative recessed sections 23 to make them more conspicuous.

[0022] The base portion 11 has a structure that is a roughly rectangular parallelepiped that is flattened in the vertical direction, with a fork insertion groove 17 in the center in the horizontal direction H2. The fork insertion groove 17 is a rectangular groove shape that extends in the front-rear direction H1 and opens downwards at both ends. Furthermore, as shown in Figure 3, inclined surfaces 17S are formed at both ends of the upper surface inside the fork insertion groove 17. Moreover, as shown in Figure 2, multiple protrusions 19T extending in the front-rear direction H1 are formed on the lower surfaces of the pair of legs 19 on either side of the fork insertion groove 17 in the base portion 11.

[0023] The front and rear surfaces 11S of the base portion 11 are vertical planes that hang down from a pair of inclined surfaces 12S of the lower part 12. In addition, one side surface 11T of the base portion 11, which is also the side surface of one of the legs 19, is recessed laterally in the H2 direction in a stepped manner compared to the side surface 12T of the lower part 12, and a horizontal first stepped surface 11D1 is formed between these two side surfaces 11T and 12T.

[0024] Furthermore, a drain section 28 is provided below the first stepped surface 11D1, at a position offset to one side from the center in the front-rear direction H1. As shown in Figure 4, the drain section 28 has a structure in which a cylindrical body protruding from the side surface 11T has screw threads 28R on its outer surface. The cap 92 is then screwed onto the drain section 28, closing the drain opening 28K at the tip of the drain section 28. Also, as shown in Figure 2, the cap 92 attached to the drain section 28 is positioned below the first stepped surface 11D1 and does not protrude laterally in the direction H2 from the side surface 12T of the lower part 12.

[0025] Furthermore, in the lower part 12, the portion that protrudes laterally H2 from the base portion 11 has arc-shaped curved surfaces 12R formed at both ends in the front-to-back direction H1.

[0026] As shown in Figure 1, the other side surface 11T of the base portion 11 is flush with the side surface 12T of the lower portion 12 up to an intermediate position in the vertical direction. A second stepped surface 11D2 is formed at the lower end of the side surface 11T, and the area below the second stepped surface 11D2 is an inclined surface 11E. This inclined surface 11E is also the side surface of the other leg portion 19.

[0027] Below the second stepped surface 11D2 of the base portion 11, a pair of connecting pieces 22 are provided at positions near both ends in the front-to-back direction H1. Each connecting piece 22, when viewed from the front-to-back direction H1, has a horizontally elongated trapezoidal shape with a pair of hypotenuses. One hypotenuse of the connecting piece 22 is connected to the inclined surface 11E, and approximately half of the upper side of the connecting piece 22 is connected to the second stepped surface 11D2, while approximately half of the connecting piece 22 protrudes from the base portion 11 in the lateral direction H2. Furthermore, as shown in Figure 2, the lower surface of the connecting piece 22 is flush with the lower surface of the leg portion 19 and is located above the lower end of the aforementioned protrusion 19T. Moreover, one connecting piece 22 is positioned further towards the center in the front-to-back direction H1 by the thickness of the connecting piece 22 than the other connecting piece 22. In addition, each connecting piece 22 is provided with a through hole 34 that penetrates through to the front-to-back direction H1 at the center in the lateral direction H2 and the vertical direction.

[0028] Furthermore, the base portion 11 has horizontally elongated rectangular recessed areas 24 for attaching labels formed on both the front and rear surfaces 11S of one of the legs 19. A label containing the owner's information of the barricade 10 can be attached to these recessed areas.

[0029] As shown in Figure 1, the upper part 14 is provided with a first connecting part 15R and a second connecting part 18 at both ends of the upper body 14H in the lateral direction H2. The upper body 14H has a structure in which a roughly rectangular parallelepiped, which is flattened in the vertical direction, has an upper groove 20 in the center in the lateral direction H2. The upper body 14H also protrudes in a stepped manner on both sides in the front-rear direction H1 from a pair of main planes 13S of the intermediate part 13. As shown in Figure 3, a pair of horizontal stepped surfaces 13D are formed between the front and rear surfaces 14S of the upper body 14H and the pair of main planes 13S of the intermediate part 13. Also, as shown in Figure 1, a pair of side surfaces 14T of the upper body 14H are recessed in the lateral direction H2 from both sides 13T of the intermediate part 13 as a whole.

[0030] A water inlet 21 is provided on the bottom surface of the top groove 20, at a position near one end in the front-rear direction H1. As shown in Figure 3, the water inlet 21 has a cylindrical structure with screw threads 21R on its outer circumference, which protrudes from the side surface 11T, and is equipped with a water inlet 21K at its tip. As shown in Figure 1, a cap 91 is screwed onto the water inlet 21 to close the water inlet 21K. The cap 91 attached to the water inlet 21 is designed not to protrude upward from the top surface of the upper body 14H.

[0031] The first connecting section 15R consists of a first block 15 and a second block 16. The first block 15 extends laterally in the direction H2 from approximately half of the front side surface 14T of one side surface 14H of the upper body 14H, and the second block 16 extends laterally in the direction H2 from the side surface 15T of the first block 15. In the upper body 14H, the first block 15, and the second block 16, the front and top surfaces are flush and continuous, while the rear surfaces are stepped forward. Furthermore, the side surface 15T of the first block 15 is flush and continuous with one side surface 13T of the intermediate section 13, and the entire second block 16 protrudes laterally in the direction H2 from one side surface 13T of the intermediate section 13.

[0032] At the other end of the upper part 14 in the lateral direction H2, a stepped corner recess 39 is provided at the upper corner of one end of the lateral direction H2 in the intermediate part 13, and the side surface 39T of the corner recess 39 and the other side surface 14T of the upper part 14 are flush and continuous. When viewed from the rear, the second connecting part 18 forms a vertically elongated rectangle with a height from the upper surface of the upper body 14H to the bottom surface of the corner recess 39, and protrudes in the lateral direction H2 from the front half of the aforementioned flush side surfaces 14T and 39T, with half of the lateral direction H2 extending from the side surface 13T of the intermediate part 13.

[0033] Furthermore, the upper surface of the second connecting portion 18 is flush with the upper surface of the upper body 14H. Moreover, the front surface of the second connecting portion 18 is flush with the front surface of the upper part 14, except for the portion opposite the corner recess 39, and the portion of the front surface of the second connecting portion 18 opposite the corner recess 39 is flush with the main plane 13S of the intermediate portion 13.

[0034] The first connecting portion 15R is provided with a pair of through holes 31 that penetrate in the front-rear direction H1. These pair of through holes 31 are arranged vertically on the boundary between the first block 15 and the second block 16. Furthermore, on the rear side of the first connecting portion 15R, a pair of arc-shaped grooves 32 are formed on the extension of the pair of through holes 31 in the side surface 15T of the first block 15. In addition, an annular projection wall 31K (see Figure 5(A)) is provided inside the through holes 31, extending inward from an intermediate position in the penetration direction.

[0035] A long hole 33 is provided near the upper end of the second connecting portion 18, penetrating in the front-rear direction H1. The long hole 33 extends in the lateral direction H2. Inside the long hole 33, an annular projection wall 33K (see Figure 5(B)) is provided, which protrudes inward from an intermediate position in the penetrating direction.

[0036] As shown in Figure 1, a circular recess 25 is formed on the upper surface of the second connecting portion 18, closer to the front, and a rectangular groove 26 is provided in front of the recess 25, opening to both the upper surface and the front of the second connecting portion 18.

[0037] The barricade 10 is vertically divided into a pair of segments 41 and 42 at an intermediate position in the thickness direction of the front-to-back direction H1, and these segments 41 and 42 are fixed to each other. Segments 41 and 42 are injection-molded resin products and have different colors. The resin fixing surfaces of segments 41 and 42 are located, for example, within a common, flat, hypothetical joint surface.

[0038] Specifically, as shown in Figure 4, the rear segment 41 has a structure in which multiple internal ribs 41L and connecting beams 41M are located inside the outer shell wall 41G that forms the outer surface of the barricade 10, and the front segment 42 similarly has a structure in which multiple internal ribs 42L and connecting beams 42M are located inside the outer shell wall 41G.

[0039] The outer shell wall 41G of the rear segmented body 41 mainly consists of a first wall portion 51 facing the front-rear direction H1 of the barricade 10 and a second wall portion 52 substantially parallel to the front-rear direction H1, with the second wall portion 52 protruding from the entire outer edge of the first wall portion 51. In addition, the second wall portion 52 is provided between the stepped portions of the first wall portion 51, except for the outer edge. Furthermore, the multiple internal ribs 41L are parallel to the front-rear direction H1 and connect the first wall portion 51 and the second wall portion 52 at the outer edge. Moreover, the connecting beam 41M has a cross-shaped cross section and extends in the front-rear direction H1 from substantially the center of the first wall portion 51. The end faces of the second wall portion 52, the multiple internal ribs 41L, and the connecting beam 41M on the side away from the first wall portion 51 are located within the aforementioned hypothetical joint surface. Furthermore, the outer shell wall 41G is thicker than the internal ribs 41L and connecting beams 41M. The shape of the rear segment 41 described above is the same for the front segment 42.

[0040] As shown in Figure 5(A), a pair of cylindrical bodies 53 are provided in the portion of the front divided body 42 corresponding to the pair of through holes 31 of the first connecting portion 15R, projecting in the front-rear direction H1 from the first wall portion 51, and annular projection walls 31K protrude inward from the tips of these cylindrical bodies 53. Also, as shown in Figure 5(B), an oval-shaped cylindrical body 54 is provided in the portion of the front divided body 42 corresponding to the elongated hole 33, projecting in the front-rear direction H1 from the first wall portion 51, and an annular projection wall 33K protrudes inward from the tip of this cylindrical body 54. The tip surfaces of these cylindrical bodies 53 and 54 and the main planes of the annular projection walls 31K and 33K are located within the aforementioned hypothetical joining surface.

[0041] As shown in Figure 5(A), the second wall portion 52 of the stepped portion of the first wall portion 51 in the first connecting portion 15R of the rear divided body 41 is provided with a pair of semicircular bulges 55 corresponding to a pair of arc grooves 32, and a pair of cylindrical bodies 53 extend from one end of these semicircular bulges 55. An annular projection wall 31K protrudes inward from the tip of these cylindrical bodies 53. In addition, the portion of the rear divided body 41 corresponding to the elongated hole 33 is provided with an oval-shaped cylindrical body 54 protruding from the first wall portion 51, with an annular projection wall 33K protruding inward from its tip, and an oval-shaped cylindrical body 56 protruding from the inner opening edge of the annular projection wall 33K. The tip surfaces of the cylindrical bodies 53 and 56 and the main plane of the annular projection wall 31K are located within the aforementioned hypothetical joint surface. Furthermore, the aforementioned water inlet section 21 and drainage section 28 are formed together in the rear segmented body 41.

[0042] Figure 6 shows a magnified view of the joint-side ends of the outer shell walls 41G and 42G before the divided bodies 41 and 42 are fixed together. Receiving grooves 41Y and 42Y are formed on the tip surfaces of these outer shell walls 41G and 42G, extending around the entire circumference and positioned near the outer edge. The outer walls of the receiving grooves 41Y and 42Y are lower than the inner wall portions relative to their bottom surfaces. In the state before the divided bodies 41 and 42 are fixed together, the tip surfaces of the internal ribs 41L and 42L, connecting beams 41M and 42M, etc., are flush with the portion of the tip surfaces of the outer shell walls 41G and 42G that is inside the receiving grooves 41Y and 42Y. The divided bodies 41 and 42 are then placed against a heated iron plate at their joint-side ends and then overlapped together. This fixes the divided bodies 41 and 42 together. At this time, the molten resin generated by heat welding is received into the receiving grooves 41Y and 42Y.

[0043] The barricade 10 can be assembled into a barricade unit 10U as follows. Specifically, as shown in Figure 7, a pair of barricades 10 are placed side by side in the horizontal direction H2 with their front and rear facing opposite directions and their first connecting portion 15R sides facing each other. The first connecting portions 15R and connecting pieces 22 of both barricades 10 are then overlapped in the front-to-back direction H1. Next, a bolt 93 (see Figure 1) is passed through a pair of through holes 31 so as to penetrate the overlapping first connecting portions 15R, and the nuts 94 are screwed in. The bolts 93 heads and nuts 94 are then tightened until they are pressed against the annular projection 31K (see Figure 5(A)) inside the through holes 31. At this time, by selecting a bolt 93 of a predetermined length, the entire fastener consisting of the bolt 93 and nut 94 can be made not to protrude from the outer surface of the barricade 10. Next, one pair of barricades 10 are lowered, and bolts 95 are passed through the through holes 34 (see Figure 1) of the two pairs of connecting pieces 22 that overlap each other, and screwed with nuts (not shown). As a result, the pair of barricades 10 are fixed in a horizontal direction H2, forming a barricade unit 10U. Furthermore, once the barricade unit 10U is formed, as shown in Figure 10, the fence 70 can be erected on top of the barricade unit 10U by inserting the pair of legs 71 of the fence 70 into the pair of recesses 25.

[0044] As shown in Figures 8 and 9, the barricades 10 can be connected in a bent state when viewed from above. In this case, a pair of barricades 10 are placed with their front and rear facing opposite directions, with the second connecting portion 18s facing each other, and aligned in the lateral direction H2. Then, the second connecting portions 18s of both barricades 10 are overlapped in the front-to-back direction H1. Next, a bolt 96 (see Figure 19(A)) is passed through the elongated hole 33 of the overlapping second connecting portion 18 and screwed with a nut 97 (see Figure 9(B)). At this time, the bolt 96 head and the nut 97 are screwed in such a way that they are not pressed against the annular projection 33K inside the elongated hole 33. Then, the other barricade 10 is tilted to an arbitrary position relative to one barricade 10. This connects the pair of barricades 10 in a bent state. The barricade units 10U can be connected to each other, and the barricade units 10U and the barricade 10 can be connected to each other in a similar bent state. Alternatively, the barricades 10 can be fixed together by tightening the second connecting parts 18 together in the front-rear direction H1 within the elongated hole 33 until the heads of the bolts 96 and nuts 97 are pressed against the annular projection 33K.

[0045] This concludes the explanation of the configuration of the barricade 10 in this embodiment. Next, an example of how the barricade 10 can be used will be described. The barricades 10 are transported to the construction site, for example, in a separate state. At the construction site, the barricades 10 are fixed together in pairs to form a barricade unit 10U (see Figure 7). Then, multiple barricade units 10U are lined up and connected along the boundary of the construction site (see Figure 11). In this state, water is injected into each barricade 10 from the water injection section 21 using, for example, a water tanker, water supply hose, etc. Then, a fence 70 is erected on each barricade unit 10U. In this way, a wall with a fence 70 can be easily constructed along the boundary of the construction site. Alternatively, water may be supplied to each barricade 10 of the barricade unit 10U at a certain location before the barricade unit 10U is transported by a forklift or the like.

[0046] Furthermore, during the above work, before water is injected into the barricade 10, for example, the barricade 10 can be easily transported by placing fingers on the stepped surface 13D (see Figure 3) of the barricade 10, and even the barricade unit 10U can be easily transported by two people placing their hands on the first connecting part 15R and the second connecting part 18 from below. Moreover, after water has been injected into the barricade 10, the barricade unit 10U can be easily transported by inserting a pair of forks of a forklift into a pair of fork insertion grooves 17 of the barricade unit 10U.

[0047] The barricade 10 of this embodiment provides the following effects. Specifically, according to the structure of the barricade 10 of this embodiment, it can be manufactured by injection molding a pair of divided parts 41 and 42 and then fixing them together. In other words, the barricade 10, which is a hollow resin molded product, can be manufactured by injection molding rather than blow molding or rotational molding. This suppresses the uneven thickness that is a problem in blow molding and rotational molding, and improves the durability of the barricade 10 compared to conventional barricades. Furthermore, the productivity of the barricade 10 is also improved. Moreover, internal ribs 41L and 42L, which cannot be provided in blow molding or rotational molding, are provided inside the barricade 10, increasing its strength and improving the durability of the barricade 10 in this respect as well. In addition, since the opposing surfaces of the barricade 10 are connected via connecting beams 41M and 42M, deformation that causes the barricade 10 to bulge due to internal pressure is prevented. Furthermore, since the barricade 10 is equipped with multiple protrusions 19T on its underside, it prevents problems such as holes being formed in the bottom of the barricade 10 even if it is dragged along the road surface.

[0048] Furthermore, since the barricade 10 is equipped with a water inlet 21K and a drain outlet 28K, water can be added to the barricade 10 to stabilize its self-supporting state, and drainage can be easily performed when it is removed. In addition, the water inlet 21K and drain outlet 28K are provided away from the fixing surfaces of the pair of divided parts 41 and 42, and are not positioned to straddle the pair of divided parts 41 and 42, so the shape of the water inlet 21K and drain outlet 28K is stable, and the waterproofing performance is improved when they are closed with caps 91 and 92.

[0049] Furthermore, a pair of barricades 10 can be fixed together to form a barricade unit 10U. In other words, the barricade unit 10U can be transported in halves, making it easy to handle. Moreover, since the barricade units 10U can be connected to each other, the overall strength of a wall made up of multiple barricade units 10U can be increased. In addition, the barricades 10U have different colors on the front and back, so a wall made up of multiple barricade units 10U will have barricades 10 of different colors arranged alternately in the horizontal direction, thus enhancing its function as a warning device.

[0050] [Other embodiments] (1) The barricade 10 of the above embodiment may be capable of storing water, but may not have a water injection section 21 and a drainage section 28, and may not be capable of storing water.

[0051] (2) In the above embodiment, the barricade 10 was fixed by heat welding a pair of divided parts 41 and 42, but they may also be fixed by vibration welding or adhesive.

[0052] (3) In the above embodiment, multiple through holes 31 for fixing the barricades 10 together and elongated holes 33 for tiltically connecting the barricades 10 together are arranged separately on both sides in the lateral direction H2. Alternatively, a structure may be provided in which both ends of the lateral direction H2 are equipped with multiple through holes for fixing and elongated holes for tiltically connecting.

[0053] (4) The fasteners used to connect the barricades 10 in the above embodiment were bolts and nuts, but are not limited to these, and may be cable ties, rivets, etc.
