Description

[Technical field]

[0001] The present invention relates to a foundation reinforcement structure and foundation reinforcement fittings for partition fences, as well as a foundation reinforcement method, and in particular to a structure that can effectively reinforce the foundation on which the posts of a partition fence are erected, reinforcing fittings therefor, and a foundation reinforcement method using such reinforcing fittings. [Background technology]

[0002] Conventionally, fences including a plurality of posts erected on the ground at a predetermined distance and a net member such as a wire mesh stretched between the posts have been used as a means for separating a predetermined area of ​​the ground from other areas. For example, in addition to intrusion prevention fences (intrusion prevention fences) intended to prevent people and animals other than those involved from entering the premises of a highway or the like to ensure traffic safety and to prevent illegal occupation of road premises, fences installed on the boundaries of cultivated land to prevent wild animals from entering, and further, protective fences for falling rocks, avalanches, collapsed soil, etc., and outer fences for houses, factories, sports fields, etc. are well known as partition fences. Examples of these are also disclosed in JP 2016-199849 A, JP 60-184955 A, and JP 4629806 A.

[0003] By the way, such fences are designed to withstand loads (forces) in the direction opposite the fence, in other words, perpendicular to the fence surface, by fixing the bottom of each post to a foundation buried in the ground, thereby preventing the fence from falling over or tilting. However, a partition fence can be subjected to loads greater than the design load due to a sudden impact from a collision with an object, wind pressure from a strong wind, or pressure from accumulated snow, and if this causes the fence to fall over or tilt, it will no longer function as a fence.

[0004] Furthermore, even if it becomes necessary to increase the height of the posts that make up an existing fence by installing a new animal intrusion prevention fence or a new snow accumulation prevention structure on top of the existing fence, the support strength of the posts of the foundation is not sufficient, and it becomes extremely difficult to support the high posts on the existing foundation and prevent them from falling over. For example, a normal partition fence is generally installed at a height of about 1.5m, but if the fence is made 2.5m high to prevent wild animals such as deer from jumping over, if the high posts that make up a fence of that height are erected on the existing foundation as they are, when a load is applied to the fence surface, the posts will not be able to withstand the load and will be prone to tilting or falling over, which will result in the inherent problem of the fence being damaged.

[0005] One way to increase the pressure resistance or load-bearing characteristics of a fence would be to increase the burial length (depth) of the foundations that are buried underground. However, making the burial depth deeper not only makes the work of burying the foundations more difficult, but also increases the economic burden. Furthermore, when replacing an existing foundation with a deeper one, or when installing a new, deeper foundation, problems arise in which the work is difficult and complicated, and a large economic burden is incurred.

[0011] In addition, according to another preferred embodiment of the foundation reinforcement structure in a partition fence according to the present invention, the blades are respectively arranged on both side surfaces of the cylindrical body located in a direction perpendicular to the opposing direction of the two tapered portions.

[0012] Furthermore, according to another preferred aspect of the foundation reinforcement structure in a partition fence according to the present invention, the blades have a right-angled trapezoidal shape, with the side fixed to the side of the cylinder being the lower base and the end protruding from the side of the cylinder being the upper base, one leg located on the upper axial side of the cylinder being perpendicular to the upper and lower bases, and the other leg located on the lower axial side of the cylinder being an inclined side extending at an angle from the upper base toward the lower base.

[0013] Furthermore, in the present invention, a construction method is advantageously adopted in which the reinforcing metal fittings are extrapolated to the foundation and pressed into the ground so that the blades are positioned in the direction in which the supports are connected.

[0014] In addition, according to yet another preferred embodiment of the foundation reinforcement structure in a partition fence according to the present invention, the foundation is constructed of a steel pipe, and the lower part of the support is inserted into and fixed to the steel pipe.

[0015] The present invention relates to a reinforcing metal fitting that is preferably used in the foundation reinforcement structure of the above-mentioned partition fence, which is a reinforcing metal fitting for a foundation buried in the ground and extends a predetermined height from the ground, and has a plurality of posts connected at a predetermined distance apart and a net member stretched between the posts, and which comprises a cylindrical body having a tapered lower end that is extrapolated onto the foundation, and at least one blade that is fixed to the side of the cylindrical body, extends in the direction of the cylindrical axis and spreads out laterally, and which is characterized in that the blade is positioned in the ground around the foundation when the cylindrical body is extrapolated onto the foundation and pressed into the ground.

[0016] In addition, according to one preferred embodiment of the foundation reinforcement fitting according to the present invention, the cylinder is made of a cylindrical body, and the lower part of the cylindrical shape is cut away from both sides downward so that they approach each other, thereby forming two opposing triangular tapered parts.

[0017] According to another preferred embodiment of the foundation reinforcement fitting according to the present invention, the blades are respectively arranged on both side surfaces of the cylindrical body located in a direction perpendicular to the opposing direction of the two tapered portions.

[0018] Furthermore, according to another preferred embodiment of the foundation reinforcement fitting according to the present invention, the wing is characterized in that the side that is fixed to the side of the cylinder is the lower base, the end side protruding from the side of the cylinder is the upper base, and one leg located on the upper axial side of the cylinder is perpendicular to the upper and lower bases, and the other leg located on the lower axial side of the cylinder has an inclined side that extends at an angle from the upper base toward the lower base, forming a right-angled trapezoid shape.

[0019] In addition, the present invention also relates to a foundation reinforcement method using foundation reinforcing fittings as described above, which is a reinforcement method for a partition fence that is erected on a foundation buried in the ground and extends a predetermined height from the ground, has a plurality of posts connected at a predetermined distance apart, and a net member stretched between the posts, and which uses foundation reinforcing fittings of the above-mentioned configuration, and the cylindrical body of the foundation reinforcing fitting is extrapolated onto the foundation, and the foundation reinforcing fittings are pressed into the ground, thereby positioning the blades in the ground around the foundation. Effect of the Invention

[0020] According to the foundation reinforcement structure and foundation reinforcement method for a partition fence of the present invention, in which reinforcing fittings according to the present invention are inserted and arranged around the outer periphery of a foundation buried in the ground that supports the posts that make up the partition fence, the reinforcement of the foundation to which the reinforcing fittings are inserted can be effectively achieved by simply pressing the reinforcing fittings into the ground and placing the blades on the reinforcing fittings in the ground around the foundation.This advantageously increases the support strength of the posts supported by such a foundation, and therefore, even if a large load is applied to the partition fence, the tipping or tilting of the fence can be effectively suppressed or prevented.

[0021] Therefore, even if the height of the fence or the height of the posts is increased, the strength of the foundation and the supporting strength of the posts can be effectively increased by pressing the reinforcing metal fittings according to the present invention into the ground, so there is no need to carry out special foundation installation work such as deepening the embedding depth of the foundation or burying new foundations.By following the present invention, it is possible to improve the pressure resistance or load-bearing characteristics of the fence with the simple task of pressing in the reinforcing metal fittings, and in an economical manner.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0023] In order to clarify the configuration of the present invention more specifically, representative embodiments of the present invention will be described in detail below with reference to the drawings.

[0024] First, Fig. 1 shows a front view of a part of an example of a partition fence in which the foundations supporting the posts are reinforced according to the present invention. The partition fence 10 is used as an animal jump prevention fence for preventing people and animals other than those involved from entering a specific area such as a highway, ensuring traffic safety, preventing illegal occupation of road land, and preventing animals such as deer from jumping over the top of the fence. The fence is composed of a plurality of foundations 12 arranged (connected) on the ground at a predetermined distance apart, a plurality of posts 14 erected on each of the foundations 12, wire mesh 16 as a net member stretched between the posts 14, and a mesh panel 18 stretched at a predetermined height on the top of the wire mesh 16 to prevent animals from jumping over.

[0025] Specifically, in the partition fence 10, the foundation 12 is made of a steel pipe with a circular cross section similar to that of a conventional one, and is buried in the ground to a predetermined depth, for example, about 500 to 600 mm, in order to support the posts 14 erected integrally thereon, and is disposed at a predetermined distance along the boundary of the area to be partitioned. The posts 14 are generally long objects made of metal, particularly iron or steel, and here, pipes with a cylindrical cross section are used. The lower parts of the multiple posts 14 are inserted into the steel pipe of the foundation 12 and fixed with a hardening agent such as mortar 28, as shown in FIG. 2(b), so that the posts 14 are supported. In addition, upper furring strips 20a and lower furring strips 20b made of long L-shaped metal brackets or the like are fixed to the multiple posts 14 at the normal fence height portion (here, the portion extending to a height of approximately 1,400 mm from the foundation 12) to connect the upper and lower portions of the posts. Additionally, horizontal frame wires 22, 22 made of metal wire are hung horizontally at positions dividing the space between the upper and lower furring strips 20a, 20b into thirds, and a diamond-shaped metal wire mesh 16 similar to that of a conventional fence is stretched across the space to form the fence main body 24.

[0026] A mesh panel 18 is stretched between the posts 14, 14 that protrude above the fence main body 24, and is made by assembling and fixing iron wires of a predetermined thickness (here, 4 mmφ) in a lattice pattern (for example, 150 mm x 150 mm), forming a net section 26 for preventing animals such as deer from jumping over. The height of the jump-prevention net section 26 is appropriately selected depending on the target animal, and is set to a height of about 1000 mm to 1100 mm here. Each post 14 is set to a height corresponding to the total height of the fence main body 24 and the jump-prevention net section 26, and therefore is selected here to be about 2500 mm above ground.

[0027] In the partition fence 10 consisting of the fence main body 24 and the anti-jump net 26, the posts 14 constituting the fence 10 are higher above ground than the height of a normal fence, so there is a risk that the posts 14 and thus the partition fence 10 may tilt or fall over due to the impact of animals or objects against the fence surface, wind pressure from strong winds, loads applied by snow blocks, etc. For this reason, in the present invention, as is clear from Fig. 1 and Figs. 2(a) and (b) which show an enlargement of part X of Fig. 1, in a form in which the posts 14 are extrapolated to each foundation 12, the reinforcing metal fittings 30 are pressed into the ground and arranged around the foundations 12 to reinforce the foundations 12, so that the posts 14 can effectively support the load applied to the partition fence 10 and improve the pressure resistance.

[0028] Such reinforcing bracket 30 is basically configured to have a structure comprising a cylindrical body with a tapered lower end that is extrapolated onto the foundation 12, and at least one blade that is fixed to the side of the cylindrical body, extends in the axial direction of the cylinder, and spreads out laterally.Here, it is used in the shape shown in Figures 3 and 4.

[0029] Specifically, as is clear from the plan view, front view, and right side view shown in Figures 3(a) to (c) and the perspective view shown in Figure 4, the reinforcing metal fitting 30 is composed of a cylindrical body 32 of a predetermined length and two blades 34, 34 that are welded and fixed to the cylindrical body 32 at symmetrical positions in the circumferential direction (with a phase difference of 180° in the circumferential direction). Both the body 32 and the blades 34 are made of a metal material such as iron or steel.

[0030] The cylindrical body 32 is formed of a cylinder with a wall thickness of about 2 mm to 5 mm, and the lower part of the cylindrical shape is cut away from both sides so that they approach each other downward, here, inclined downward at an angle of 30° with respect to the pipe axis, as is clear from Figures 3(b) and 4, to form two opposing triangular tapered parts 32a, 32a, which makes it easy to press the reinforcing metal fitting 30 into the ground by driving it in. The thickness and axial length of the cylindrical body 32 are appropriately selected according to the degree of reinforcement of the target foundation, and for example, the inner diameter is selected to have a dimension that forms a gap of about 3 mm to 10 mm between the outer circumferential surface of the foundation 12, and the axial length is selected to give a length such that the underground burial length excluding the tapered part 32a is about 150 to 400 mm.

[0031] Furthermore, on the side of the cylindrical body 32 in such reinforcing bracket 30, vanes 34 extending in the cylindrical axis direction are positioned in a direction perpendicular to the opposing direction of the two tapered portions 32a, 32a, with the cylindrical axis between them, as is clear from Figures 3(a) and (b), in other words, positioned with a phase difference of 180° from each other and with a phase difference of 90° from the tapered portion 32a, and are fixed and arranged by welding or the like to both side portions of the cylindrical body 32. In addition, each of the blades 34 is arranged in a shape such that the side fixed to the side of the cylindrical body 32 is the lower base, the end protruding from the side of the cylindrical body is the upper base, and one leg located on the upper axial side of the cylindrical body 32 is perpendicular to the upper and lower bases, and the other leg located on the lower axial side of the cylindrical body 32 has an inclined side extending at an angle from the upper base to the lower base, thereby advantageously reducing resistance to the pressing-in of the reinforcing bracket 30 while effectively resisting the tipping load acting on the partition fence 10.

[0032] With regard to the size of the blades 34, their lateral protrusion length from the cylinder 32 and their axial length (top edge length, inclination angle of the inclined edge) are appropriately selected according to the reinforcing effect provided by the reinforcing metal fittings 30; for example, the lateral protrusion length is selected to be approximately 100 mm to 300 mm, and the top base length and inclination angle are selected so that the axial length is an overall length of approximately 100 mm to 300 mm.

[0033] The reinforcing metal fitting 30 having such a configuration is used to press and position it in the ground around the foundation 12, for example, as shown in Fig. 5. That is, as shown in Fig. 5(a), the reinforcing metal fitting 30 is inserted from the upper end of the support 14 erected on the aboveground exposed portion of the foundation 12 buried in the ground, and the upper part of the foundation 12 is positioned inside the cylindrical body 32. By performing a press-in operation such as hitting the upper end of the cylindrical body 32 with a hammer, the reinforcing metal fitting 30 is pressed into the ground as shown in Fig. 5(b), and finally, the press-in of the reinforcing metal fitting 30 is completed in a form in which the upper end of the cylindrical body 32 and the upper end of the foundation 12 coincide with each other as shown in Fig. 5(c), whereby the wings 34, 34 provided on the reinforcing metal fitting 30 are positioned in the ground around the foundation 12, and can function as a resistance against the support 14, and therefore the partition fence 10, from falling over. In this embodiment, the two blades 34, 34 provided on either side of the cylindrical body 32 of the reinforcing bracket 30 are positioned and arranged to extend in the direction in which the multiple supports 14 are connected together, as shown in Figure 1, thereby enabling the supports 14 to more effectively resist tipping over.

[0034] Furthermore, the reinforcing structure of the foundation 12 using such reinforcing metal fittings 30 can of course be applied to a newly constructed partition fence 10, but is particularly advantageously employed in cases where it is necessary to increase the support capacity of the foundation 12 for the posts 14 by, for example, increasing the height of the posts 14 in an existing partition fence 10. In such cases, the existing foundation 12 can be used as is to be reinforced advantageously without the need to construct a new foundation. When applying the reinforcing metal fittings 30 to such an existing foundation 12, it is possible to effectively reinforce the existing foundation 12 by press-fitting the reinforcing metal fittings 30 around the existing foundation 12 prior to the placement of new posts 14 on the existing foundation 12, according to a method for restoring an existing fence, as disclosed in Japanese Patent No. 7324474, for example.

[0035] Although typical embodiments of the present invention have been described above in detail, it should be understood that these are merely examples, and that the present invention should not be construed in any way as being limited to the specific descriptions of such embodiments.

[0036] For example, in the illustrated embodiment, the foundation 12 is made of a circular steel pipe, but its cross-sectional shape may be any shape other than circular or rectangular, and the shape of the tubular body 32 of the reinforcing metal fitting 30 is selected so as to have a cross-sectional shape that corresponds to that cross-sectional shape. Furthermore, as is well known, the foundation 12 may be in the shape of a concrete block or columnar body, and in that case, it goes without saying that the tubular body 32 of the reinforcing metal fitting 30 is configured so as to have a shape that corresponds to the outer diameter shape of such a concrete foundation.

[0037] Furthermore, the support pillars 14 are not limited to pipes having a circular cross-sectional shape, but may have a triangular cross-sectional shape, as is well known, or may have various other cross-sectional shapes such as H-shape, L-shape, hat-shape, etc.

[0038] Furthermore, in the specific example, the cylindrical body 32 of the reinforcing bracket 30 has its lower portion cut away from both sides to form two opposing tapered portions 32a, 32a, which enables the reinforcing bracket 30 to be effectively pressed into the ground; however, the tapered shape of the lower end of the cylindrical body 32 is not limited to this exemplary form, and it is also possible to adopt a lower end shape in which a single tapered portion is formed by simply cutting the lower portion of the cylindrical body 32 diagonally downward, and further, it is also possible to adopt a form in which one or more tapered portions having other known tapered shapes are provided.

[0039] In addition, in the illustrated embodiment, two blades 34, 34 are fixed to the side surface of the cylinder 32 of the reinforcing metal fitting 30 with a phase difference of 180° in the circumferential direction, but the number of blades can be selected appropriately, and for example, it is possible to configure with one blade 34, or it is also possible to arrange three blades 34 with a phase difference of 120°, or even four blades 34 with a phase difference of 90°. In addition, even with regard to the shape of such blades 34, a right-angled trapezoid shape as shown in the example is recommended as the most effective shape, but shapes such as a normal trapezoid shape and a rectangular shape can also be appropriately adopted.

[0040] Furthermore, the pressing-in operation of the reinforcing bracket 30 can be performed as shown in Figure 5, or it can be arranged so that the reinforcing bracket 30 is inserted outside the foundation 12 and pressed into the ground before the support 14 is erected on the foundation, and then the support 14 is erected.

[0041] In the illustrated embodiment, the partition fence that is the subject of the present invention has been described as an intrusion prevention fence for preventing animals from jumping over, but the present invention is not limited to this, and it would also be acceptable for the intrusion prevention fence to be made by increasing the height of the fence main body 24 itself without providing a jump-over prevention net portion 26.In addition, the present invention can also be used for other fences such as protective fences against falling rocks, avalanches, collapsing soil, etc., and the outer frames of houses, factories, playgrounds, etc.

[0042] In addition, although not listed one by one, the present invention can be implemented in various forms with various changes, modifications, improvements, etc. based on the knowledge of those skilled in the art, and it should be understood that all such embodiments belong to the scope of the present invention as long as they do not deviate from the spirit of the present invention.
