Description

  The present invention relates to a connected boundary block that is connected and laid in the longitudinal direction to form a section or boundary.

  The present inventor has both ends formed in an arc shape at the longitudinal end of the block main body, and an upper protrusion formed by projecting the upper side to one end of the both ends, The other side of the opposite side is provided with a lower protruding part formed by protruding the lower side to the side, and when fitted to an adjacent concrete block, the fitting part can be rotated as a fulcrum. A precast for foundation construction comprising: a fitting convex portion formed in a circular convex shape on the upper surface of the lower protruding portion; and a fitting concave portion formed in a circular concave shape on the lower surface of the upper protruding portion. A concrete block is proposed (Patent Document 1).

  Such a precast concrete block for foundation construction is useful in that it can be installed regardless of the curvature of the road, regardless of the straight section or the curved section, and form a section or boundary.

However, roads are not always flat and often have undulations and slopes in the longitudinal direction of the road, such as hills and valleys. When the above-mentioned precast concrete block for foundation construction is laid on a road having such undulations and slopes, as shown in FIG. 15, the lower surface 4a of the upper protruding portion 3a and the upper surface 4b of the lower protruding portion 3b do not become parallel surfaces. For example, the front end of the upper protruding portion 3a interferes with the upper surface 4b of the lower protruding portion 3b, and the fitting recess 5a and the fitting protrusion 5b are floated to each other, so that there is a problem that reliable fixing cannot be performed. there were. In addition, when the road surface has a twist, the same problem occurs because the precast concrete block for foundation construction is twisted and arranged.

  Therefore, the present invention has been made in view of such problems, and even on roads with ups and downs, slopes, twists, etc., adjacent blocks can be connected to each other without the fitting part floating, and stable. The main object is to provide an articulated block that can be laid.

  In order to achieve the above-mentioned object, the present invention employs the following means.

The connected boundary block according to the present invention is:
In a connected boundary block that is fitted and arranged in the longitudinal direction and constitutes a partition or boundary,
An upper protrusion protruding from the upper side of the one end side in the longitudinal direction; and a fitting recess having a substantially hemispherical recess formed on the lower surface of the upper protrusion;
A downward projecting portion projecting in the longitudinal direction from the lower side of the other end portion, and a substantially hemispherical convex fitting convex portion formed on the upper surface of the lower projecting portion,
The distance between the lower surface of the upper protrusion and the deepest part of the fitting recess is shorter than the distance between the upper surface of the lower protrusion and the top of the fitting protrusion.

  Such a connection type boundary block is provided with an upper protrusion and a lower protrusion at both ends of one connection type boundary block, a fitting recess on the lower surface of the upper protrusion, and a fitting protrusion on the upper surface of the lower protrusion. is there. The connection type boundary block according to the present invention is laid on the road with the connection type blocks arranged in series by fitting the fitting convex part of another connection type boundary block into the fitting concave part. The connected boundary block laid in this manner is prevented from moving (displaced) in the horizontal direction by the fitting convex portion and the fitting concave portion. Further, the fitting convex part and the fitting concave part are formed in a hemispherical shape, and the distance between the lower surface of the upper protruding part and the deepest part of the fitting concave part is between the upper surface of the lower protruding part and the top part of the fitting convex part. Since a gap is provided between the lower surface of the upper projecting portion and the upper surface of the lower projecting portion, the distance between the upper projecting portion lower surface and the lower projecting portion upper surface can be inclined in various directions such as a height direction and a twist direction other than the horizontal direction. Thus, since it can arrange | position inclining mutually, even if it is a road with ups and downs, a gradient, a twist, etc., a connection type | mold boundary block can be laid stably, without a fitting convex part and a fitting recessed part removing.

Furthermore, the connected boundary block according to the present invention is:
In a connected boundary block that is fitted and arranged in the longitudinal direction and constitutes a partition or boundary,
An upper protrusion protruding from the upper side of the one end side in the longitudinal direction, and a substantially hemispherical convex protrusion formed on the lower surface of the upper protrusion;
A downward projecting portion projecting in the longitudinal direction from the lower side of the other end portion, and a substantially hemispherical concave recessed portion formed on the upper surface of the lower projecting portion,
The distance between the upper surface of the lower protrusion and the deepest part of the fitting recess is shorter than the distance between the lower surface of the upper protrusion and the top of the fitting protrusion.

  Such a connection type boundary block is obtained by reversing the positions of the fitting convex portion and the fitting concave portion with respect to the above-described invention. That is, a substantially hemispherical fitting convex portion is provided on the lower surface of the upper protruding portion, and a fitting concave portion is provided on the upper surface of the lower protruding portion. Although the unevenness is reversed, it has the same effect as the above-described connected boundary block.

The connected boundary block according to the present invention is:
In a connected boundary block that is fitted and arranged in the longitudinal direction and constitutes a partition or boundary,
A first connection type boundary block having an upper protrusion protruding from the upper side of at least one end side in the longitudinal direction and a substantially hemispherical concave fitting recess formed on the lower surface of the upper protrusion; ,
A second connection type boundary having a downward projecting portion projecting from the lower side of at least one end side in the longitudinal direction, and a substantially hemispherical convex fitting projection formed on the upper surface of the lower projecting portion. A block, and
The distance between the lower surface of the upper protrusion and the deepest part of the fitting recess is shorter than the distance between the upper surface of the lower protrusion and the top of the fitting protrusion.

  In such a connection type boundary block, the connection type boundary block moves in the horizontal direction (displacement) by fitting the fitting convex part of the second connection type boundary block into the fitting recess of the first connection type boundary block. Is suppressed. Further, the fitting convex part and the fitting concave part are formed in a hemispherical shape, and the distance between the lower surface of the upper protruding part and the deepest part of the fitting concave part is between the upper surface of the lower protruding part and the top part of the fitting convex part. Since it is shorter than the distance and a gap is provided between the lower surface of the upper protruding portion and the upper surface of the lower protruding portion, it can be freely arranged by tilting each other in various directions such as a height direction and a twist direction other than the horizontal direction. . Thus, since it can arrange | position inclining mutually, even if it is a road with ups and downs, a gradient, a twist, etc., a connection type | mold boundary block can be laid stably, without a fitting convex part and a fitting recessed part removing.

Further, the connected boundary block according to the present invention is:
In a connected boundary block that is fitted and arranged in the longitudinal direction and constitutes a partition or boundary,
A first connected boundary block comprising: an upper protruding portion that protrudes from the upper side of at least one end side in the longitudinal direction; and a substantially hemispherical fitting protrusion formed on the lower surface of the upper protruding portion. When,
A second connecting type boundary block comprising: a lower protruding portion that protrudes from the lower side of at least one end side in the longitudinal direction; and a substantially hemispherical concave recessed portion formed on the upper surface of the lower protruding portion; With
The distance between the upper surface of the lower protrusion and the deepest part of the fitting recess is shorter than the distance between the lower surface of the upper protrusion and the top of the fitting protrusion.

  The invention which concerns reverses the fitting convex part and fitting concave part of a 1st connection type | mold boundary block and a 2nd connection type | mold boundary block which were mentioned above. That is, a substantially hemispherical fitting convex portion is provided on the lower surface of the upper protruding portion, and a fitting concave portion is provided on the upper surface of the lower protruding portion. Although the unevenness is reversed, it has the same effect as described above.

  Further, the connection type boundary block according to the present invention is configured such that when the fitting convex part of the previous connection type boundary block and the fitting concave part of the adjacent connection type boundary block are fitted, the upper protruding part and the end A gap may be formed between the first protrusion and the lower protrusion and the end.

  Thus, by forming a gap between adjacent connection type boundary blocks, it becomes possible to rotate in the horizontal direction around the fitting convex part or the fitting concave part. Therefore, the connected boundary block can be continuously laid along the curved road.

  Furthermore, as for the connection type | mold boundary block which concerns on this invention, at least 1 of the said edge part, the front-end | tip of the said upper protrusion part, and the front-end | tip of the said lower protrusion part may be formed in the arc shape.

  By adopting such a configuration, even if the adjacent connected boundary block is largely rotated in the horizontal direction, the upper protruding portion or the lower protruding portion does not interfere with the end portion of the adjacent connected block. Therefore, a wide rotation range can be secured, and the connected boundary block can be continuously laid along the road having a tight curve.

  Further, in the coupled boundary block according to the present invention, the lower surface of the upper protruding portion or the upper surface of the lower protruding portion may be an inclined surface.

  By adopting such a configuration, it is possible to make it difficult to disengage the fitting concave portion and the fitting convex portion according to the inclination angle. Further, the lower surface of the upper projecting portion and the upper surface of the lower projecting portion can be brought close to a horizontal plane according to the gradient of the road to be laid, and the block can be easily laid.

  Furthermore, the connection type boundary block which concerns on this invention WHEREIN: The upper surface of the said upper protrusion part and the upper surface of the said lower protrusion part may be formed in the curved surface.

  By adopting such a configuration, it is possible to increase the bending angle in the height direction and the twist direction between the connected boundary blocks. Further, for example, if a cylindrical surface is adopted, it becomes possible to arrange the connected blocks at a large angle only in a certain direction.

  Further, in the connection type boundary block according to the present invention, an interference escape portion may be provided at least at either the lower end tip of the upper protruding portion or the upper end tip of the lower protruding portion.

  By adopting such a configuration, it is possible to lay the connection type boundary block without the interference of the upper projecting portion or the lower projecting portion even when the inclination is suddenly changed.

  According to the connection type boundary block according to the present invention, the adjacent connection type boundary blocks are fitted and connected by the substantially hemispherical fitting recesses and the fitting projections, respectively, so that the height direction, the twist direction, etc. It can be freely tilted in various directions. By being able to be arranged in an inclined manner in this way, it is possible to stably lay a connected boundary block without detaching the fitting convex part and the fitting concave part even on roads with undulations, slopes, twists, etc. it can.

  Hereinafter, embodiments for carrying out the present invention will be described in detail with reference to the drawings. In addition, the Example and drawing demonstrated below exemplify a part of embodiment of this invention, and is not used for the objective limited to these structures. In addition, the same or similar code | symbol is attached | subjected to the corresponding component in each figure.

  FIG. 1 is a perspective view showing an outline of the configuration of a connected boundary block 100 according to a first embodiment of the present invention. As shown in FIG. 1, the connection type boundary block 100 includes a block main body 10, an upper protruding portion 13a protruding from the upper side of one end 12a of the block main body 10 in the longitudinal direction, and an upper protruding portion 13a. A fitting recess 15a having a substantially hemispherical concave shape formed on the lower surface 14a, a lower protruding portion 13b protruding from the lower side of the other end 12b of the block body 10 in the longitudinal direction, and an upper surface 14b of the lower protruding portion 13b. And a substantially hemispherical convex protrusion 15b.

  The block body 10 generally has a portion (lower portion) embedded in the ground when laid and a portion (upper portion) that protrudes above the road surface to form a boundary. The shape is generally formed so that the cross section is substantially rectangular, but as shown in FIG. 2, the corners of the upper part are rounded (FIG. 2a), or the upper half is trapezoidal ( 2b), the upper half may be shorter than the lower half (FIG. 2c). Further, as shown in FIG. 2d, it may be of a type in which one side is completely buried in the ground. In such a case, one side is formed perpendicularly and the upper portion has a right angle. The height of the block body is not limited, and the ratio of the lower part and the upper part is not particularly limited.

  As described above, the upper protruding portion 13a is formed to protrude outward in the longitudinal direction from the one end portion 12a of the block body 10, and a substantially hemispherical fitting recess 15a is formed on the lower surface 14a of the upper protruding portion 13a. Is formed. Here, the substantially hemispherical shape does not necessarily need to be a complete hemisphere, and may be, for example, a part of a hemisphere whose center is formed below the lower surface 14a, or an elliptical sphere. It means good. Further, the size of the substantially hemispherical fitting recess 15a is not limited as long as it is formed on the lower surface 14a. Further, the length of the upper protruding portion 13a is not limited. However, when the upper protruding portion 13a is connected with the fitting convex portion 15b of another similar connecting type boundary block (see FIG. 3), it can move mutually. In order to secure a region, it is preferable to set the length such that the gap A is generated between the upper protruding portion 13a and the end portion 12b.

  The downward protruding portion 13b is formed to protrude outward in the longitudinal direction from the other end portion 12b of the block body 10. The length of the protrusion is not limited, but it is lower in order to secure a movable area when it is connected with a fitting recess of another similar connecting type boundary block (see FIG. 3). The length is preferably such that a gap B is generated between the protruding portion 13b and the end portion 12a. A substantially hemispherical fitting convex portion 15b is formed on the upper surface 14b of the downward projecting portion 13b. The meaning of the substantially hemispherical shape is not necessarily completely hemispherical as described above, and may be, for example, a part of a hemisphere whose center is formed below the upper surface 14b, or an elliptical spherical shape. It means that it may be.

  The fitting concave portion 15a and the fitting convex portion 15b described above are formed such that the depth of the fitting concave portion 15a is lower than the height of the fitting convex portion 15b. That is, as shown in FIG. 3, the distance C between the lower surface 14a of the upper protrusion 13a and the deepest portion α of the fitting recess 15a is the distance between the upper surface 14b of the lower protrusion 13b and the topmost portion α of the fitting protrusion 15b. It is shorter than the distance D. Accordingly, a gap E is formed between the lower surface 14a of the upper protrusion 13a and the upper surface 14b of the lower protrusion 13b.

  As shown in FIG. 3, the connection type boundary block 100 according to the first embodiment configured in this way is used by fitting and connecting the fitting convex portion 15 b to the fitting concave portion 15 a and laying it on the road. In the case of roads with undulations and slopes, the connected boundary blocks 100 and 100 connected in this way, as shown in FIG. 4, the fitting recess 15a and the fitting projection 15b are in contact with each other in a spherical shape. The gap E can be continuously arranged in a state where the gap is bent in the height direction within a range in which the tips of the upper protrusion 13a and the lower protrusion 13b do not interfere with each other.

  Further, even on a road with a twist, as shown in FIG. 5, the connecting boundary blocks 100, 100 are in contact with each other in a spherical shape with the fitting concave portion 15a and the fitting convex portion 15b. 14a and the upper surface 15a of the lower protruding portion are arranged continuously in a twisted state around the fitting concave portion 15a and the fitting convex portion 15b as long as the upper protruding portion 13a and the lower protruding portion 13b do not interfere with each other. can do.

  Thus, according to the connection type | mold boundary block 100 which concerns on Example 1, even if it is a slope, an undulating surface, a road surface with a twist, etc., in the state connected reliably, without a fitting part shifting | deviating or coming off. In addition, it can be connected and arranged in various directions such as a height direction and a twist direction.

  Furthermore, according to the connection type | mold boundary block 100 which concerns on Example 1, when fitting the fitting convex part 15b of the connection type | mold boundary block 100 and the fitting recessed part 15a of the adjacent connection type | mold boundary block 100, it is upward. Since gaps A and B are formed between the projecting portion 13a and the end portion 12b and between the lower projecting portion 13b and the end portion 12a, as shown in FIG. Can be laid. Further, if a block having a short block body length is used, it is possible to cope with a road with a tight curve.

  Further, when the connection type boundary block 100 is laid by providing the gaps A and B, as shown in FIG. 7, there is a case where a drainage groove for draining water such as rain exists only on one side. However, rainwater can escape from the gap to the opposite side.

  In addition, this invention is not limited to Example 1 mentioned above at all, and can be implemented in various aspects as long as it belongs to the technical scope of this invention.

  For example, in the first embodiment described above, the fitting concave portion 15a is formed on the lower surface 14a of the upper protruding portion 13a of the block body 10, and the fitting convex portion 15b formed on the upper surface 14b of the lower protruding portion 13b. A fitting convex part may be formed in the lower surface 14a of the upper protrusion part 13a of the block main body 10, and a fitting recessed part may be formed in the upper surface 14b of the downward protrusion part 13b. Even if such a configuration is adopted, the relationship between the projections and depressions is turned upside down, but the same effect as in the first embodiment can be obtained.

  FIG. 8 is a perspective view showing an outline of the configuration of the connection boundary block 100 according to the second embodiment of the present invention. As shown in FIG. 8, the connection type boundary block 100 includes a block main body 10 and an upper protruding portion 13a protruding from the upper side of one end 12a of the block main body 10 in the longitudinal direction. A substantially hemispherical concave fitting recess 15a formed on the lower surface 14a of the upper projecting portion 13a, a lower projecting portion 13b projecting from the lower side of the other end 12b of the block body 10 in the longitudinal direction, and the lower projecting portion. And a fitting convex portion 15b having a substantially hemispherical convex shape formed on the upper surface 14b of 13b. Further, the distance between the lower surface 14a of the upper protruding portion and the deepest portion of the fitting concave portion 15a between the fitting concave portion 15a and the fitting convex portion 15b is the distance between the upper surface 14b of the lower protruding portion and the topmost portion of the fitting convex portion 15b. The same is true in that a gap E is formed between the lower surface 14a of the upper protrusion 13a and the upper surface 14b of the lower protrusion 13b.

  Therefore, similarly to the first embodiment, even on slopes, undulating surfaces, twisted road surfaces, and the like, it can be laid on the road in a state of being securely connected without the fitting part being displaced or detached. The same is true for the effect.

  The connection type boundary block 100 according to the second embodiment is different in that all of the upper protruding portion 13a, the lower protruding portion 13b, and the end portions 12a and 12b are formed in an arc shape. By adopting such a configuration, it is possible to bend and arrange at 90 ° or more. Therefore, as shown in FIG. 9, even a road having a fairly tight curve can be arranged along the curve.

  In addition, by adopting the above configuration, the upper projecting portion 13a and the end portion 12b, and the lower projecting portion 13b and the end portion 12a do not interfere with each other, so that a curved road can be formed without forming a gap between them. Can respond.

  Moreover, in the connection type | mold boundary block 100 which concerns on Example 2, in order to ensure higher stability, the upper through-hole 16a and the lower hole 16b are provided. A rod-like body such as a bolt or a reinforcing bar can be inserted and fixed in the upper through hole 16a and the lower hole 16b. At this time, the connection type boundary blocks 100 may be arranged to be inclined with respect to each other in the height direction or may be arranged to be twisted, so that the upper through plan 16a and the lower through hole 16b are formed in a conical shape or the like. Good.

  In addition, this invention is not limited to the structure of Example 2 mentioned above, and can be implemented with various aspects, as long as it belongs to the technical scope of this invention. For example, in the first embodiment described above, the fitting concave portion 15a is formed on the lower surface 14a of the upper protruding portion 13a of the block main body 10, and the fitting protrusion 15b having a substantially hemispherical shape formed on the upper surface 14b of the lower protruding portion 13b is formed. However, the fitting convex part may be formed in the lower surface 14a of the upper protrusion part 13a of the block main body 10, and the fitting recessed part may be formed in the upper surface 14b of the downward protrusion part 13b. Even if such a configuration is adopted, the relationship between the projections and depressions is turned upside down, but the same effect as in the above embodiment can be obtained.

  FIG. 10 is a perspective view showing the outline of the configuration of the connection type boundary block 100 according to the third embodiment of the present invention. The coupled boundary block 100 according to the third embodiment is a block that is laid at the end when laid on a road. The coupled boundary block 100 includes a block main body 10 and a block body 10 as illustrated in FIG. An upper projecting portion 13a projecting from the upper side of one end 12a of the block main body 10 in the longitudinal direction side, and a substantially hemispherical concave fitting recess 15a formed on the lower surface 14a of the upper projecting portion 13a are formed. . The other end of the block body 10 has an upper surface that is inclined from the approximate center of the block body 10 and is formed lower than the center of the end.

The connection type boundary block of the third embodiment is connected and arranged by fitting with a fitting convex portion at an end of the connection type boundary block 100 connected in a plurality of longitudinal directions according to the first or second embodiment. Since the fitting part is a connection in a substantially hemispherical shape, even if it is a slope, an undulating surface, a road surface with a twist, etc., the road is securely connected without the fitting part being displaced or detached. It has the effect that it can be laid in.

  Further, the tip shape of the upper protruding portion 13a may be any of a rectangular shape, an arc shape, and the like, and is appropriately selected depending on the combination of other connected blocks and the like. If it is formed in an arc shape, the upper projecting portion 13a and the end portion 12b do not interfere with each other, so that it is possible to cope with a curved road without forming a gap between them.

In addition, this invention is not limited to the structure of Example 3 mentioned above, and can be implemented with various aspects, as long as it belongs to the technical scope of this invention. For example, in Example 1 mentioned above, the fitting convex part may be formed in the lower surface 14a of the upper protrusion part 13a of the block main body 10. FIG. When such a configuration is adopted, it is used in combination with one in which a fitting recess is formed in the downward projecting portion 13b of the adjacent connected boundary block.

    FIG. 11 is a perspective view showing an outline of the configuration of the connected boundary block 100 according to the fourth embodiment of the present invention. As shown in FIG. 11, the connection type boundary block 100 includes a block main body 10, a lower protruding portion 13b protruding from the lower side of one end 12b of the block main body 10 in the longitudinal direction, and the lower protruding portion 13b. And a substantially hemispherical fitting convex portion 15b formed on the upper surface 14b.

  The other end of the block body 10 has an upper surface that is inclined from substantially the center of the block body 10 and is lower than the center of the end. The connection type boundary block 100 according to the fourth embodiment is a block laid at the end when laid on a road, and is installed on the opposite side of the connection type boundary block 100 according to the third embodiment. Therefore, it is connected and arranged by fitting with the fitting recesses of the connecting type boundary block 100 connected in the longitudinal direction according to the first embodiment or the second embodiment. Since the fitting part is a connection in a substantially hemispherical shape, even if it is a slope, an undulating surface, a road surface with a twist, etc., the road is securely connected without the fitting part being displaced or detached. It has the effect that it can be laid in.

  Further, the tip shape of the upper protruding portion 13a may be any of a rectangular shape, an arc shape, and the like, and is appropriately selected depending on the combination of other connected blocks and the like. If it is formed in an arc shape, the upper projecting portion 13a and the end portion 12b do not interfere with each other, so that it is possible to cope with a curved road without forming a gap between them.

In addition, this invention is not limited to the structure of Example 4 mentioned above, and can be implemented with various aspects, as long as it belongs to the technical scope of this invention. For example, in Example 1 mentioned above, the fitting recessed part may be formed in the upper surface 14b of the downward protrusion part 13b of the block main body 10. FIG. When such a configuration is adopted, it is used in combination with a structure in which a fitting convex portion is formed on the upper projecting portion 13a of the adjacent connected boundary block 100.

  In addition, this invention is not limited to the structure of Examples 1 to 4 mentioned above, and can be implemented in various modes as long as it belongs to the technical scope of this invention.

  For example, in the above-described embodiment, the upper protruding portion 13a or the lower protruding portion 13b of the block body 10 is a plane up to the tip, but an interference escape portion may be provided so that the tip does not interfere with an adjacent block. For example, as shown in FIG. 12, the interference escape portions 17a and 17b whose tip ends are cut obliquely may be provided, or the tip portions may be rounded. By adopting such a configuration, it is possible to install the bent by largely bending in the height direction while avoiding contact with the upper or lower surface of the adjacent connecting block.

  Further, for example, in the embodiment described above, the lower surface 14a of the upper projecting portion 13a or the upper surface 14b of the lower projecting portion 13b of the block body 10 is formed horizontally with respect to the block bottom surface, but is inclined with respect to the bottom surface. It does not matter if it is provided. For example, as shown in FIG. 13, you may form so that the front-end | tip of a protrusion part may become high with respect to a root part.

  By adopting such a configuration, the lower surface 14a of the upper projecting portion 13a or the lower surface 14a of the upper projecting portion 13a of the block body 10 can be installed in a state close to horizontal. Further, even if the connected boundary blocks 100 are moved in the direction in which they are separated from each other, it is possible to prevent the inclined surfaces from coming into contact with each other and being separated from each other. Therefore, the stability of a connection state can be ensured more.

In the embodiment described above, the lower surface 14a of the upper protruding portion 13a of the block main body 10 or the lower surface 14a of the upper protruding portion 13a of the block main body 10 is formed in a plane, but as shown in FIG. The lower surface 14a of 13a may be provided in a concave shape, and the lower surface 14a of the upper protruding portion 13a may be provided in a convex shape. By minimizing such a configuration, the lower surface 14a of the upper protruding portion 13a or the lower surface 14a of the upper protruding portion 13a of the block body 10 can ensure a large movable region even if the gap between the flat surface is narrow. Further, the movable region can be enlarged only in a certain direction depending on the shape of the curve.
Further, as shown in FIG. 15, both the lower surface 14a of the upper protruding portion 13a and the lower surface 14a of the upper protruding portion 13a may be formed in a convex shape so as to face each other. If such a configuration is adopted, the movable region can be further increased.

  As shown in the embodiment described above, it can be used as a concrete block for civil engineering, particularly as a concrete block to be laid when producing a boundary.
