Description

[Technical Field]

[0001] The present invention relates to a barricade block used in temporary facilities such as road closure barriers that restrict vehicle passage. [Background technology]

[0002] When road construction or other work is carried out on a road where vehicles travel, temporary barriers are installed on the road to restrict vehicle passage from the perspective of ensuring safety. Temporary barriers are also installed on pedestrian walkways and runways to restrict vehicle entry. Because such temporary barriers must be easy to install and durable enough to withstand vehicle collisions, temporary barriers made up of an array of multiple barricade blocks have come into practical use.

[0003] For barricade blocks, improved products have been proposed from various viewpoints, such as ease of handling and impact resistance. For example, Patent Document 1 describes a barrier assembly consisting of a combination of a main member with a protruding portion that protrudes outward and a bridge at the bottom, and a connecting member with a hole portion that corresponds to the protruding portion. Also, Patent Document 2 describes a protective barrier system composed of a hollow plastic container with multiple connecting protrusions on both sides, multiple sawtooth portions on the outer wall, and barrier blocks with metal cables inside that are connected together.

[0004] [Patent Document 1] Patent No. 2695228 [Patent Document 2] Patent No. 5571678 Summary of the Invention [Problem to be solved by the invention]

[0005] In Patent Document 1, joints on both sides of a block-shaped main component are connected with connecting members to connect them together, but the connecting members have insufficient impact resistance, and the connecting members must be fitted into the joints, which makes assembly difficult.

[0006] In Patent Document 2, the connection is made by combining connecting protrusions formed on both sides of the plastic container and inserting a pin, which makes it easy to assemble the connection part, but it is insufficient in terms of impact resistance.

[0007] SUMMARY OF THE INVENTION It is therefore an object of the present invention to provide a barricade block that is easy to assemble and has sufficient impact resistance. [Means for solving the problem]

[0008] The barricade block according to the present invention is a barricade block comprising a hollow main body formed in a substantially rectangular shape in a plan view, and connection portions formed at both longitudinal ends of the main body, wherein the main body has a plurality of long grooves formed at predetermined intervals in the up-down direction around the entire circumference of both longitudinal ends and both longitudinal sides, the connection portion formed at one end has a plurality of connection protrusions formed below each of the long grooves so as to protrude along the longitudinal direction, and the connection portion formed at the other end has a plurality of connection protrusions formed above each of the long grooves so as to protrude along the longitudinal direction, and each of the connection protrusions has a connection hole formed therein for inserting a connecting rod through it in the up-down direction. A metal reinforcing body is held in the long groove, and a connecting portion is provided on the reinforcing body to connect to the connecting rod body. There are.

[0009] The barricade system of the present invention is a barricade system in which a plurality of the above-mentioned barricade blocks are arranged along the longitudinal direction, and is equipped with a plurality of connecting rod bodies inserted through each of the aligned connecting holes formed by overlapping the connecting protrusion formed on the lower side of the long groove portion of one of the adjacent barricade blocks with the connecting protrusion formed on the upper side of the long groove portion of the other adjacent barricade block, and a plurality of metal reinforcing bodies held in the long groove portion of the barricade blocks and connected to the connecting rod bodies. [Effects of the Invention]

[0010] As the present invention has the above-mentioned configuration, multiple long groove portions are formed in the main body portion at predetermined intervals in the vertical direction around both longitudinal ends and both sides along the longitudinal direction, and a connecting protrusion portion is formed on the upper side of one end of the long groove portion and a connecting protrusion portion is formed on the lower side of the other end, so that when the barricade blocks are connected, the connecting protrusions and long groove portions are arranged in a straight line along the longitudinal direction.

[0011] The long grooves hold metal reinforcing members that are arranged in a straight line parallel to the long grooves, thereby improving the impact resistance of the outer surfaces of the barricade blocks.

[0012] In addition, when connecting barricade blocks, they can be easily assembled by overlapping the connecting protrusions formed on the upper and lower sides of the long groove portion and inserting the connecting rod body into the connecting hole, making it possible to efficiently perform tasks such as installing and removing barricade blocks.

[0013] In addition, by forming the outwardly protruding end face of the connecting protrusion into an arc shape when viewed in plan and forming the outer surface opposite the end face into a recessed receiving surface, the barricade block can be rotated around the connecting rod body even when the barricade block is connected by the connecting rod body.

[0014] Furthermore, by forming an engaging protrusion on the top surface of the main body and an engaging recess on the bottom surface of the main body, barricade blocks can be stacked one above the other and the uneven shape can provide a reinforcing effect. Furthermore, by forming an uneven shape in the center of the bottom surface of the main body, a rib shape can provide a reinforcing effect. Furthermore, by forming support through-holes between the long grooves in the main body, the support rods of a transport device such as a forklift can be inserted and the unit can be easily moved.

[0016] The following describes in detail the embodiments of the present invention. Note that the embodiments described below are preferred examples for carrying out the present invention, and therefore various technical limitations are imposed thereon. However, the present invention is not limited to these embodiments unless otherwise specified in the following description to limit the invention.

[0017] Figure 1 is a perspective view of the barricade block of the present invention as viewed from the top, and Figures 2 to 5 are a front view (Figure 2), a plan view (Figure 3), a bottom view (Figure 4), a right side view (Figure 5(a)), and a left side view (Figure 5(b)) of the barricade block.

[0018] The barricade block 1 comprises a hollow main body 10 formed in an approximately rectangular shape when viewed from above, a connection part 20 formed at one longitudinal end of the main body 10, and a connection part 30 formed at the other longitudinal end of the main body 10.

[0019] The main body 10 is molded as a hollow resin body, and can be integrally molded together with the connecting portion by blow molding or rotational molding. A water inlet is formed on the top surface of the main body 10, and a water inlet cap 11 is attached to the water inlet. A drain outlet is formed at the bottom end of the main body 10, and a drain plug 12 is attached to the drain outlet.

[0020] After carrying the empty barricade block to the installation location, water is supplied to the inside of the main body 10 through the water supply port until it is full, allowing for the installation of a barricade block of sufficient weight. When removing the barricade block, the drain port is opened to drain the water from inside, making the barricade block empty, allowing for easy movement of the now lightweight barricade block.

[0021] The resin material used for the main body 10 is preferably a material with impact resistance, and examples thereof include known resin materials such as polyethylene and polypropylene. By molding using linear low-density polyethylene (LLDPE), the container can be sufficiently durable against impacts from vehicle collisions, etc., without cracking or other deformation even when filled with water.

[0022] The main body 10 has a plurality of long grooves 13a-13c formed at predetermined intervals in the vertical direction around both longitudinal ends and both longitudinal side ends. The long grooves 13a-13c are arranged at intervals approximately twice the vertical thickness of the connecting protrusions (described later). Each long groove is formed in the longitudinal direction by recessing the both side ends with a predetermined width, and is formed between the connecting protrusions at both ends.

[0023] On the top surface of the main body 10, engaging protrusions 14a and 14b are formed and arranged in the short direction inside one of both longitudinal ends, and engaging protrusions 15a and 15b are formed and arranged in the short direction inside the other end. Also, on the bottom surface of the main body 10, engaging recesses 16a and 16b are formed and arranged in the short direction at positions corresponding to the engaging protrusions 14a and 14b, and engaging recesses 17a and 17b are formed and arranged in the short direction at positions corresponding to the engaging protrusions 15a and 15b.

[0024] Each engaging protrusion is roughly rectangular and protrudes outward, while each engaging recess is a recess slightly larger than the size of the corresponding engaging protrusion and formed inward. Therefore, when stacking barricade blocks one above the other, the lower engaging protrusion fits into the upper engaging recess, allowing for stable stacking. Furthermore, the uneven shape formed near the connecting portion provides reinforcement for both ends of the main body 10 in the event of an impact being applied to the connecting portion.

[0025] The bottom surface of the main body is formed with an uneven reinforcement portion 18 in the center. By forming a plurality of depressions of a predetermined width at predetermined intervals along the short side of the bottom surface to create an uneven shape, it is possible to obtain a reinforcement effect for the bottom surface of the main body 10, and it becomes possible to install the main body 10 in a stable shape without the bottom surface bending even when the main body 10 is full of water.

[0026] The main body 10 has a plurality of support through-holes 19 formed on the outer surface between the long grooves 13a to 13c, penetrating inward. The support through-holes 19 are integrally formed in a cylindrical shape to connect both outer surfaces, allowing for easy movement by inserting the support rod of a transport device such as a forklift. In addition, because the outer surfaces are connected by the cylindrical portions, it is possible to obtain the effect of reinforcing the outer surfaces to prevent them from bending when the container is filled with water.

[0027] The connecting portion 20 formed at one end of the main body 10 has a plurality of connecting projections 21a-21c formed below the long grooves 13a-13c so as to protrude along the longitudinal direction, while the connecting portion 30 formed at the other end of the main body 10 has a plurality of connecting projections 31a-31c formed above the long grooves 13a-13c so as to protrude along the longitudinal direction. The connecting projections 21a-21c each have a connecting hole 22a-22c formed in their central portion, through which a connecting rod body is inserted by passing through them in the vertical direction. Similarly, the connecting projections 31a-31c each have a connecting hole 32a-32c formed in their central portion, through which a connecting rod body is inserted.

[0028] Each connecting protrusion is designed to have approximately the same thickness in the vertical direction, and a gap is set between the bottom of connecting protrusion 21a and long groove 13b so that connecting protrusion 31b can be inserted, and a gap is set between the bottom of connecting protrusion 21b and long groove 13c so that connecting protrusion 31c can be inserted. Therefore, when multiple barricade blocks are arranged and connected in the longitudinal direction, adjacent connecting protrusions 31b and 31c can be inserted under connecting protrusions 21a and 21b, respectively, and combined so that they overlap.

[0029] When combined, when viewed from above, the uppermost adjacent connecting protrusion 31a and the lowermost connecting protrusion 21c also overlap with the other connecting protrusions, and the connecting rod body can be inserted through the connecting holes of each connecting protrusion.

[0030] In addition, when viewed from the side, a gap that communicates with long groove 13a is formed between adjacent connecting protrusions 31a and 21a, a gap that communicates with long groove 13b is formed between adjacent connecting protrusions 31b and 21b, and a gap that communicates with long groove 13c is formed between adjacent connecting protrusions 31c and 21c. Therefore, the long grooves of the barricade blocks that are arranged and connected in the longitudinal direction are arranged in a straight line.

[0031] The connecting protrusions 21a-21c and 31a-31c protrude outward and have end faces 23a-23c and 33a-33c that are arc-shaped in plan view. At one end of the main body 10, the upper outer surfaces of the long grooves 13a-13c are formed as receiving surfaces 24a-24c that are recessed corresponding to the end faces 33a-33c of the connecting protrusions 31a-31c, and at the other end, the lower outer surfaces of the long grooves 13a-13c are formed as receiving surfaces 34a-34c that are recessed corresponding to the end faces 23a-23c of the connecting protrusions 21a-21c.

[0032] Therefore, when connecting barricade blocks, when connecting protrusions 21a to 21c and adjacent connecting protrusions 31a to 31c are combined and the connecting rod body is inserted, end faces 23a to 23c and receiving surfaces 34a to 34c face each other, and end faces 33a to 33c and receiving surfaces 24a to 24c face each other, so that connecting protrusions 21a to 21c and adjacent connecting protrusions 31a to 31c are rotatably connected to each other around the connecting rod body, and the connected barricade blocks can be rotated around the connecting rod body to be installed.

[0033] In the example described above, the number of connecting projections formed in the connecting portion is three, but the number of connecting projections may be three or more and is not particularly limited.

[0034] Fig. 6 is a perspective view of a barricade system configured by arranging the barricade blocks shown in Fig. 1 in the longitudinal direction. In this example, three barricade blocks 1 are arranged in the longitudinal direction and connected together. Each barricade block is connected by overlapping a connecting portion 20, in which a connecting protrusion is formed on the lower side of one long groove of adjacent barricade blocks, with a connecting portion 30, in which a connecting protrusion is formed on the upper side of the other long groove, and inserting a connecting rod 40 into the connecting holes of the overlapping connecting protrusions. In the connected state, the long grooves 13a to 13c formed on the outer surface of the main body 10 are arranged linearly in the longitudinal direction of the barricade system.

[0035] Metal reinforcing members 50a-50c are respectively held in the long grooves 13a-13c of the main body 10. FIG. 7 is a perspective view showing only the reinforcing members 50a-50c, excluding the barricade blocks. Reinforcing member 50a includes reinforcing members 53a and 54a, each made of a straight metal tube and having a rectangular cross section, held in a concave recess formed on both sides of long groove 13a, a metal connecting member 51a connecting one end of reinforcing members 53a and 54a, and a metal connecting member 52a connecting the other end of reinforcing members 53a and 54a. Each reinforcing member and each connecting member is fixed with screws and attached to the entire periphery of long groove 13a.

[0036] The connecting member 51a is formed by bending a metal plate, and a flat central portion 511a disposed opposite the upper surface of the connecting protrusion 21a is formed with mounting holes 512a that align with the connecting holes formed in the connecting protrusion 21a. Both ends of the central portion 511a are formed with mounting portions 513a and 514a that are bent into an L-shaped cross section and protrude upward, and the mounting portion 513a is fixed to one end of the reinforcing member 53a by screws.

[0037] Connecting member 52a is formed by bending a metal plate into the same shape as connecting member 51a, and is attached to the other end of reinforcing members 53a and 54a in a state in which it is inverted 180 degrees from connecting member 51a. Therefore, the central portion of connecting member 52a is disposed opposite the lower surface of connecting protrusion 31a, and the mounting holes are aligned with the connection holes formed in connecting protrusion 31a, and the mounting portions on both sides protrude downward and are fixed by screws.

[0038] In the reinforcing body 50a, the connecting rod 40 penetrates through each mounting hole and is connected with a gap between the connecting member 51a arranged on the upper surface of the connecting protrusion 21a and the connecting member 52a arranged on the lower surface of the connecting protrusion 31a of the adjacent reinforcing body. Therefore, the reinforcing members 53a and 54a are stably held in a linear arrangement along the long groove.

[0039] Reinforcements 50b and 50c are configured in the same manner as reinforcement 50a, with reinforcement members 53a-53c and 54a-54c arranged linearly along the entire length of the barricade system along the linearly arranged long grooves 13a-13c.

[0040] By attaching the reinforcing members 50a to 50c to the barricade system in this way, the strength against impacts on the outer part is improved, and sufficient impact resistance can be provided.

[0041] 8 is a perspective view of another barricade system. In this example, three barricade blocks 1 are aligned longitudinally and connected together. Each barricade block is connected by overlapping a connecting portion 20, which has a connecting protrusion formed on the lower side of one long groove of an adjacent barricade block, with a connecting portion 30, which has a connecting protrusion formed on the upper side of the other long groove, and inserting a connecting rod 40 into the connecting holes of the overlapping connecting protrusions. In the connected state, the long grooves 13a-13c formed on the outer surface of the main body 10 are aligned in a straight line in the longitudinal direction of the barricade system. Reinforcements 60a-60c are installed in each of the linearly aligned long grooves, spanning the entire length of the barricade system.

[0042] 9 is a perspective view showing only the reinforcing member 60a, excluding the barricade blocks. The reinforcing member 60a includes a reinforcing member 62a made of a metal linear member such as a wire rope held in a recess formed on one side of the long groove 13a, and a support member 61a disposed on the upper surface of the connecting protrusion 21a to suspend and support the reinforcing member 62a.

[0043] The support member 61a is formed by bending a metal plate, and a flat central portion 611a disposed opposite the upper surface of the connecting protrusion 21a is provided with an attachment portion 612a that is inserted into a connection hole formed in the connecting protrusion 21a. The attachment portion 612a is formed in a cylindrical shape and protrudes downward, and is attached by inserting the cylindrical portion into the connection hole. The connecting rod 40 is inserted into the attachment portion 612a to fix the support member 61a together with the connecting protrusion 21a.

[0044] Both ends of the central portion 611a are bent into a U-shaped cross section to form support portions 613a and 614a that protrude upward, and oval mounting holes are formed in the support portions 613a and 614a.

[0045] In this example, reinforcing member 62a is provided on only one side of the barricade system, so reinforcing member 62a is attached to support portion 613a. Link member 615a connecting terminal portion 621a of reinforcing member 62a is attached to the attachment hole of support portion 613a on the terminal side of reinforcing member 62a, and reinforcing member 62a is inserted into the attachment hole of support portion 613a at the middle portion of reinforcing member 62a for support, and reinforcing member 62a is supported by being spanned across multiple support members 61a attached to each barricade block.

[0046] Similar to the supporting portion 613a, the supporting portion 614a can also be supported so that a reinforcing member is bridged across it, and it becomes possible to attach a reinforcing member as appropriate depending on the installation location.

[0047] Similar to reinforcing body 60a, reinforcing body 60b also includes connecting member 61b and reinforcing member 62b, and connecting member 61b has a central portion 611b formed with an attachment portion 612b and support portions 613b and 614b. Terminal portions 621b of reinforcing member 62b are connected with link members 615b, and the middle portion of reinforcing member 62b is inserted into the mounting hole of support portion 613b for support, so that reinforcing member 62b is supported by spanning multiple support members 61b attached to each barricade block.

[0048] Similar to reinforcing body 60a, reinforcing body 60c also includes connecting member 61c and reinforcing member 62c, and connecting member 61c has a central portion 611c formed with an attachment portion 612c and support portions 613c and 614c. Terminal portions 621c of reinforcing member 62c are connected with link members 615c, and the middle portion of reinforcing member 62c is inserted into the mounting hole of support portion 613c for support, so that reinforcing member 62c is supported by spanning multiple support members 61c attached to each barricade block.

[0049] In this way, the reinforcing members 62a-62c are aligned linearly along the entire length of the barricade system along the linearly aligned long grooves 13a-13c. Furthermore, since the intermediate portions of the reinforcing members 62a-62c are inserted into the mounting holes of the support portions, they are able to move longitudinally, and the range of rotation of the barricade blocks around the connecting rod is not restricted when the barricade blocks are connected.

[0050] In addition to the above-described metallic straight pipe and wire members, other high-strength reinforcing members can be used as the reinforcing body, and are not particularly limited. For example, known members with cross-sectional shapes such as L-shaped, H-shaped, and U-shaped can be used. Furthermore, in addition to metallic members, members made of materials having the same strength as these reinforcing members can also be used, such as resin members. [Explanation of symbols]
