Description

  The present invention relates to a bending block that is arranged in a bending portion between connected boundary blocks that are connected in the longitudinal direction and that form sections or boundaries.

  As shown in FIG. 2, the inventor forms both ends 210a and 210b in the longitudinal direction of the block body 210 in an arc shape, and the lower side of one end 210a at both ends protrudes sideways. A lower protruding portion 220 and an upper protruding portion 230 formed by protruding the upper side of the other end 210b on the opposite side to the side. A circular shape is formed on the upper surface of the lower protruding portion 220. A convex fitting convex portion 221 is formed, and a circular concave fitting concave portion 231 is formed on the lower surface of the upper protruding portion 230, and when the upper protruding portion or the lower protruding portion of the adjacent block is fitted. The foundation construction precast concrete block 200 (hereinafter referred to as a “connected boundary block”) is proposed (see Patent Document 1).Such a connected boundary block not only provides excellent installation stability as a basis for installing guardrails, etc., but can be installed regardless of the curvature of the road, regardless of straight section or curved section, forming a partition or boundary Useful in that it can. Further, the present inventor has shown a block as shown in FIG. 14 as a connected boundary block suitable for being arranged at the end of a series of connected connected boundary blocks at the same time as the connected boundary block. A precast concrete block 300 for foundation construction in which an upper protrusion or a lower mold protrusion is formed only at one end 310a in the longitudinal direction of the main body 310 (hereinafter, the block in this form is referred to as an “end-bound boundary block”). ) Is also proposed (see Patent Document 1). By arranging the end connected boundary block at the end of the series of connected boundary blocks, the aesthetic appearance of the end is adjusted.

  In order to form a section or boundary at a bent place such as a corner of a road using such a connected boundary block and an end connected boundary block, as shown in FIG. Two end boundary type boundary blocks 300 are used in a portion related to bending. Specifically, two end connection type boundary blocks 300 are arranged such that the end portions 310b are abutted with each other so as to form an angle with each other, and the connection type boundary block 200 is sequentially connected thereto. ing. However, since the bent portion formed by using the two end connection type boundary blocks 300 is not connected between the two, for example, when an automobile or the like collides, two unconnected parts are connected. There is a risk that the end boundary type connecting block 300 easily moves and separates, and not only the formed sections or boundaries are separated, but also the guard rails A installed therein are damaged. was there. In addition, when such a situation occurs, there is a problem that the blocks that have become separated obstruct the passage of the vehicle or the like, causing traffic congestion or the like.

  In addition, if the angle between the two connected end boundary blocks forming the bent portion is not accurately set, the position of the connected boundary blocks that are sequentially connected from there is shifted from the planned position. It will end up. Specifically, for example, as shown in FIG. 16, when it is planned to continuously connect the connecting boundary block 200 so that the bent portion forms 90 °, the two ends forming the bent portion are arranged. When the angle between the connecting boundary blocks 300 for a section is wider than 90 °, the connecting boundary blocks 200 that are sequentially connected from there are arranged at the planned installation positions (indicated by chain lines in FIG. 16). It is installed with a deviation from the position. And this shift in the installation position becomes more prominent as the connection length of the connection type boundary block becomes longer. In order to prevent such displacement of the installation position, it is necessary to accurately set the installation angle between the two end boundary type boundary blocks in the bent portion.

  Further, it is not aesthetically preferable that the end faces of the two end boundary type boundary blocks are exposed at the bent portion.

  Therefore, the present invention has been made in view of the above circumstances, and improves the installation stability and workability of the blocks forming the bent portions of a series of connected boundary blocks, and further improves the aesthetics of the bent portions. It is an object of the present invention to provide a bending block that can be used.

  In order to solve the above-mentioned problem, the means taken by the present invention is a bending block disposed in a bending portion between connected boundary blocks that are connected in the longitudinal direction to form a partition or boundary, and is adjacent to one of them. A first block part having a first connection end to which the connection type boundary block is connected, and a second block part having a second connection end to which the connection type boundary block adjacent to the other is connected. The bent block is characterized in that the first block portion and the second block portion are formed to form an angle with each other.

  The bent block according to the present invention is suitable for use in combination with the above-described connected boundary block that has already been proposed by the present inventor, and a bent portion is formed between the connected connected boundary blocks. Is to do. That is, the bent block includes a first block portion having a first connection end portion to which a connection type boundary block adjacent to one side is connected, and a second connection end portion to which a connection type boundary block adjacent to the other is connected. The first block portion and the second block portion are formed at an angle with each other. As a result, the bent portion of the series of connected boundary blocks can be formed by a single bent block, so that even if an automobile or the like collides, it does not move easily, and the formed compartments and boundaries are disturbed. This can be prevented. In addition, since the angle of the bent portion is determined by the angle formed by the first block portion and the second block portion, the angle adjustment work at the time of installation becomes unnecessary, and a sense of unity of the block at the bent portion can be obtained. Aesthetics can also be enhanced.

  The first connecting end portion may be a protruding portion in which the upper side or the lower side of the end portion of the first block portion protrudes laterally so as to be fitted to the upper protruding portion or the lower protruding portion of the adjacent connected boundary block. Well, the second connecting end also protrudes laterally so that the upper or lower end of the second block part protrudes sideways so as to fit with the upper protruding part or the lower protruding part of the adjacent connected boundary block. It is good. By adopting such a configuration, it becomes possible to connect to the upper protruding portion or the lower protruding portion of the connecting boundary block proposed by the present inventor. For example, if the first connection end or the second connection end of the bending block according to the present invention is formed as a lower protrusion, the upper protrusion of the connection type boundary block is overlapped and fitted to these. can do.

  Moreover, a fitting convex part or a fitting recessed part may be formed in the fitting surface side of a protrusion part. When the fitting convex portion or the fitting concave portion is formed on the fitting surface side of the protruding portion, that is, the surface side overlapping with the upper protruding portion or the lower protruding portion of the connected boundary block to be connected, The fitting recesses or fitting projections formed in the upper protrusions or the lower protrusions can be fitted and connected.

  Further, the first block portion and / or the second block portion may be provided with a column erecting hole for erecting a column on the upper surface. The connection type boundary block that the present inventor has already proposed can be used as a foundation for erecting a column for attaching a road accessory such as a guardrail or a road sign. Therefore, in the bending block according to the present invention, it is preferable to form a column erecting hole that can erect a column.

  Moreover, the corner | angular part of the outer surface between a 1st block part and a 2nd block part may be chamfered. As a result, the outer surface becomes a smooth shape and the aesthetics can be enhanced, and the chance that an automobile or the like comes into contact with the corner portion when passing near the bent portion can be reduced.

  According to the bending block according to the present invention, the first block portion having the first connection end to which the connection type boundary block adjacent to one side is connected, and the second connection to which the connection type boundary block adjacent to the other is connected. By forming the second block portion having the end portion at an angle with each other, it is possible to form the bent portion in the series of connected boundary blocks as one block. Thereby, even if an automobile or the like collides with the bent portion, it is difficult to move easily, and it is possible to prevent the alignment of the formed sections and boundaries from being disturbed. In addition, since the bending angle is determined at the stage of manufacturing the block, it is not necessary to adjust the angle at the time of installation, and it is possible to obtain a sense of unity in the block at the bent portion and enhance the aesthetics.

  The present invention provides a first block portion having a first connection end portion to which a connection type boundary block adjacent to one side is connected, and a second block having a second connection end portion to which a connection type boundary block adjacent to the other side is connected. It is a bending block provided with a block part.

  The bending block which concerns on this invention is connected with the connection type | mold boundary block connected in a longitudinal direction and forming a division or a boundary. For this reason, the form of the 1st block part and the 2nd block part in the bending block which concerns on this invention, and the form of the 1st connection end part and the 2nd connection end part which are formed in these, respectively are adjacent connection type boundaries Various configurations can be employed to suit the shape of the block.

  More preferably, a higher effect is exhibited by combining with the above-described connected boundary block that the present inventor has already developed. Therefore, first, the form of a connected boundary block suitable for use in combination with the bending block according to the present invention will be described.

  As a connection type boundary block suitable for being combined with the bending block according to the present invention, for example, both end portions in the block body longitudinal direction are formed in an arc shape, and the lower side of one end portion projects sideways. A lower projecting portion formed on the upper surface of the lower projecting portion, and an upper projecting portion formed by projecting the upper side of the other end on the opposite side to the side. A mating convex portion is formed, and a circular concave fitting concave portion is formed on the lower surface of the upper protruding portion, and the fitting convex portion of the upper protruding portion or the lower protruding portion of the adjacent connected boundary block is fitted. When they are combined, the fitting portion can be used as a fulcrum and can be rotated. By connecting the connected boundary blocks, sections or boundaries can be formed regardless of the straight section or the curved section. In this connection type boundary block, the fitting convex portion and the fitting concave portion may be provided interchangeably between the upper protruding portion and the lower protruding portion.

  When the bending block according to the present invention is connected to the connection type boundary block, the first connection end formed in the first block portion and the second connection end formed in the second block portion are the upper side or The lower side is formed as a protruding portion protruding sideways. In this case, the protrusion is formed in a form corresponding to the upper protrusion or the lower protrusion of the connected boundary block to be connected. For example, when the protrusion is connected to the upper protrusion of the connection type boundary block, the protrusion is formed as a corresponding lower protrusion, and the protrusion is connected to the lower protrusion of the connection type boundary block. Is formed as an upper protrusion corresponding to this. In addition, the shapes of the end portions of the first block portion and the second block portion including the upper protrusion portion and the lower protrusion portion are not particularly limited, but when the end portion of the connected boundary block is formed in an arc shape According to this, the end portions of the first block portion and the second block portion may be formed in an arc shape. This is because, by adopting this configuration, it is possible to ensure a wide rotation range when it is necessary to form an angle with the connected boundary block.

  Further, when the first connection end and the second connection end are formed as protrusions, the fitting surface side of the protrusion, that is, the upper protrusion or the lower protrusion of the connected boundary block to be connected A fitting convex portion or a fitting concave portion may be formed on the side of the surface overlapping with. Thereby, for example, when the fitting recess is formed in the upper protrusion of the connected boundary block to be connected, the fitting protrusion is formed in the protrusion of the bent block, so that the fitting recess And the fitting convex part can be fitted and connected. Accordingly, the shape of the fitting recess or fitting protrusion formed in the protrusion is not particularly limited as long as it is a shape corresponding to the fitting recess or fitting protrusion of the connected boundary block to be connected. When the fitting concave portion of the mold boundary block is a circular concave shape, it is preferable that the fitting convex portion in the protruding portion is formed in a circular convex shape corresponding to this. This is because, in the case of such a configuration, when the angle adjustment with the connected boundary block is necessary after installation, the connected boundary block can be rotated around the fitting portion.

  Moreover, you may form the support | pillar standing hole for standing the support | pillar to which road accessories, such as a guard rail and a road sign, are attached to the upper surface of a 1st block part and a 2nd block part. The column support hole is a hole having a diameter equal to or larger than that of the column, and may be formed to penetrate to the lower surface of the first block part or the second block part, or may be formed to a depth halfway. .

  The bent block according to the present invention is formed by forming the first block portion and the second block portion configured as described above at angles. The bent portion is formed by arranging the bent block between a series of connected boundary blocks. In other words, the angle formed by the first block portion and the second block portion determines the angle of the bent portion of the series of connected boundary blocks. The angle formed by the first block portion and the second block portion is not particularly limited as long as it has the function of bending the arrangement of the connected boundary blocks, and is appropriately set between 0 ° and 180 °. can do.

  Moreover, you may chamfer the corner | angular part of the outer surface between a 1st block part and a 2nd block part. As a form of chamfering, for example, it may be a flat shape in which corners are cut off straight, or an arc shape that draws a curved surface. By performing such chamfering, unnecessary protrusions are eliminated from the bent portion, so that the chance of contacting the corner of the bent block when an automobile or the like passes near the bent portion can be reduced. Moreover, since the shape of the outer side surface of a bending part becomes smooth, aesthetics can also be improved.

  Further, the bending block according to the present invention may be used as a “placement type” placed on the ground together with a connected boundary block connected thereto, or as a “main installation type” embedded in the ground. May be.
