Description

  The present invention relates to a fixture used by driving into the ground in order to fix a sheet-like material including a weedproof mat or a sediment runoff prevention mat used for the purpose of controlling weeds or adjusting the ground temperature. In particular, the present invention relates to a fixing device such as a sheet used on a soft ground suitable for fixing the sheet-like material well in a soft ground made of a ground having a high water content or sand. Is.

  Conventionally, for the purpose of controlling weeds or adjusting the ground temperature, the surface of a farm where seedlings are cultivated or the surface of farmland where various crops are cultivated is made of vinyl, non-woven fabric, net-like fabric, etc. An appropriate number of pin structures or pile structures are driven into the periphery of the sheet-like material or an appropriate intermediate portion so that the sheet-like material does not move due to wind and rain, etc. It is fixed so that it does not become discrete.

  On the other hand, for the purpose of securing visibility and aesthetics, the side edges of general roads and the median strips of expressways, etc., are used as appropriate in order to suppress the occurrence of weeds and trees, etc. It is generally carried out by laying sheet-like materials, etc., and fixing each sheet-like material, etc. using an appropriate fixing tool. In order to prevent the destruction and collapse of slopes, and also the slopes and side walls of slopes, etc. of various roads under construction, use appropriate fixings for the respective sheet-like materials on the parts. , Fixing is also done frequently.

For fixing each sheet-like material used in the part adjacent to the road, the sheet-like material can be used not only by natural wind and rain, but also by the wind pressure accompanying the traveling of a large vehicle such as a truck or bus. 21085; has been frequently crushed, blown up or blown, and it is required to use a fixture with a higher fixing effect.
As such a fixture, a fixture having a structure as shown in FIG. 6 of Japanese Patent Laid-Open No. 7-103218 (Patent Document 1) has been conventionally used. Then, since the resistance force of the fixture in the ground is extremely weak, it can be easily pulled out only by applying a slight pulling force. However, it has the disadvantage that it has a poor function of being fixed to the ground surface.

In order to improve the drawbacks of the related art, for example, as shown in Japanese Patent Application Laid-Open No. 10-2035 (Patent Document 2), the fixed leg portion embedded in the ground inside the ground has an appropriate shape, and the leg portion A sheet fixture has been developed with one or more protrusions protruding laterally from the surface, but the overall strength of the fixture having such a structure is weak and the pull-out resistance is It was not sufficient, and therefore it was poor in practicality.

On the other hand, as a further improvement of the conventional fixture, a fixture having a plurality of protrusions arranged on the legs as shown in JP-A-6-245655 (Patent Document 3) has been developed. However, such a fixture has a complicated structure and uses more raw materials, so that the cost increases and it is not suitable for practical use.
As a technique for further improving the above-described conventional fixing tool, for example, as shown in FIG. 1 to FIG. 5 of the above-mentioned JP-A-7-103218 (Patent Document 1), the fixing tool is buried in the ground. A wall portion of the hole formed in the hole of the ground is provided with an expandable blade at the tip of the leg, and when the fixture receives a pulling force, the blade is expanded. 1 shows a fixture having a structure in which the leading end of the blade part bites into and increases the pulling resistance.

However, although the fixing device that can have such a structure certainly has an improved pulling resistance and is recognized as a fixing device that is difficult to pull out, the fixing device is a ground that is sandy or contains a lot of moisture. In a so-called soft ground, the effect is almost diminished, and it is impossible to fully exhibit the fixing effect.

Similarly, as shown in Japanese Patent Application Laid-Open No. 2002-235323 (Patent Document 4), a structure in which a large number of protrusions are arranged and formed on the embedded leg portion of the fixture on the ground to increase the pulling resistance. However, in the case of the so-called soft ground, the effect is almost diminished and it is impossible to fully exhibit the fixing effect.

  Japanese Patent Laid-Open No. 2011-97899 (Patent Document 5) arranges a plurality of protrusions on the outer surface of a leg portion composed of two steel plates having a function of expanding each other. When the leg is embedded in the desired ground, the leg is narrowed and easily inserted into the ground, and then the leg exerts its own repulsive force. Since the outer surface of the leg portion is configured to act so as to press against the wall surface in the ground, it is described with respect to the structure of the fixture with further improved pulling resistance, Even if it is such a fixture, in the so-called soft ground, the actual situation is that the effect is hardly exhibited.

If the fixtures are easily removed, the number of repairs and additional work increases, which increases the maintenance and management costs of the sheet-like material, and the fixtures along the road. Is scattered on the road, etc., there is a high possibility that it will lead to the occurrence of traffic accidents due to damage to the tires of the vehicles and the scattering of the fixtures, and secondary disasters such as damage to human bodies and damage to buildings. , There is concern that the cost will be considerable.
The utility model registration No. 3192843 is a fixing tool for fixing and holding a sheet for soft ground, which improves the above-mentioned many problems and is easy to install and provides sufficient pulling resistance.
Has been developed and put into practical use as an effective product. However, the only problem with this type of product is that when the sheet fixture is embedded from above the sheet into the ground, at least the rod-shaped body part of the main body part passes through the hole and the vicinity thereof. In the case where there is a gap and a crack portion is generated, especially when the pull-out resistance portion similarly penetrates the sheet, a larger hole portion or a crack portion is generated. And since weeds are generated from such portions, there is a new problem that a large management cost is required for the removal work.

Therefore, there are a considerable number of areas and zones with soft ground where it is necessary to actually use the sheet-like material as described above. Therefore, in the soft ground, the sheet-like material, etc. There is a demand for the development of such a fixture that can effectively suppress the generation of weeds together with the grate that is fixed and held effectively over a long period of time.

It is fixed using the means.
That is, in the present invention, a T-bar portion formed by the second rod-like body 16 is formed at the distal end portion 4 of the first rod-like body 15.

As will be described later, the second rod-like body 16 according to the present invention is formed in such a sheet shape after the fixture 100 such as the sheet-like material is passed through an appropriate weedproof sheet 200 and embedded in a soft ground. While functioning as a rotation assisting tool for rotating a fixing tool such as an object to an appropriate angle, an operation of driving the fixing tool 100 such as a sheet is performed using a driving assisting means such as a hammer. At the same time, it also has a function of a head part that receives a predetermined striking operation.

Accordingly, the positional relationship between the second rod-like body 16 and the tip portion 4 of the first rod-like body 15 is particularly important, and as shown in FIG. 2 may be joined to the end of the front end portion P2 of the first rod-like body 15, and a joining process 18 such as welding may be performed at that portion, or FIG.

You may make it do.

Furthermore, as shown in FIG. 2 (C), the portion P3 of the center portion of the second rod-shaped body 16 moved downward by a predetermined distance W from the tip portion P2 of the first rod-shaped body 15. It may be bonded to a part and a bonding process 18 such as welding is performed at that part.
On the other hand, the structure of the pulling resistance portion 10 provided in the fixture 100 such as the sheet-like material in the present invention will be described in detail below.

That is, the fixing device 100 according to the present invention includes at least one pull-out resistance portion 10 on an appropriate surface portion Q between the both end portions 2 and 4 of the main body portion 1. It is provided to extend in the direction of.
That is, the pulling resistance portion 10 according to the present invention is directed outward from the surface portion Q in a direction basically unrelated to the arrangement direction of the second rod-shaped body 16 as shown in FIG. Projecting and extended.

More specifically, as shown in FIG. 1, the pull-out resistance portion 10 in the present invention has a predetermined length in a direction substantially perpendicular to the central axis O of the first rod-like body 15 of the main body portion 1. The pull-out resistance portion 10 is extended around the central axis O of the main body 1 with respect to the central axis O of the first rod 15 of the first rod 15. It is formed so as to be arranged in an arbitrary direction on a horizontal plane including the pull-out resistance portion 10 when it is extended in a direction perpendicular to the surface, and protrudes outward from the surface portion Q. The resistance member 5 and one end 6 thereof are joined to the outer surface Q of the first rod-like body 15 of the main body 1 and have a predetermined angle with respect to the center line O from the joining surface Q1. And in any direction, diagonally, upwards and Protruding end 7 of the second resistance member 9 protruding toward the it is, has a configuration that has been brought joined with the projecting direction of the end portion 8 of the first resistance member 5.

Each of the first and second resistance members 5 and 9 is made of a metallic material, a synthetic resin material, or a composite material thereof, and is a narrow strip having a width of 5 mm to 20 mm. Ends 5 ′ and 6 that are configured in a shape and joined to the outer surface Q of the main body 1 and the free ends 8 and 7 of the first and second resistance members 5 and 9, etc. It joins by well-known means, such as a suitable adhesive agent, joining mechanism, and welding.

The first resistance member 5 is preferably composed of a substantially linear flat plate or rod, but the second resistance member 9 is a flat plate or rod having an appropriate curved shape. It may be composed of a body.

Moreover, since the space | gap part 11 is formed in the inside of the frame, and the both sides of the space part 11 are maintained in the open state, the extraction resistance part 10 according to the present invention is free from earth and sand such as sand. It is possible to easily pass through the space 11.

Further, the extension length of the first resistance member 5 of the pull-out resistance portion 10 from the outer surface Q of the main body portion 1 is not particularly specified, but is, for example, 10 mm to 20 mm, preferably 12 mm. It may be set to a length of 16 mm.
Furthermore, the drawing resistance portion 10 according to the present invention may be provided on the outer surface Q of the main body portion 1 or may be provided in plural.

In the present invention, when a plurality of the drawing resistance portions 10 are arranged, a plurality of the drawing resistance portions 10, 10 ′, 10 ″, and the like are uniform along the longitudinal direction line of the main body portion 1. Alternatively, they may be arranged so as to protrude in the same direction through non-uniform predetermined intervals, or may be arranged so as to protrude in different directions.

In the present invention, when a plurality of the pull-out resistor portions 10 are arranged, the size or shape of the plurality of pull-out resistor portions 10, 10 ', 10 "or the like or outside the main body surface Q At least a part of the protruding length in the direction may be different from those of other pull-out resistance portions.

On the other hand, in the present invention, there is provided a plate-like body portion 17 that is fitted to the first rod-like body 15 and is in contact with or in the vicinity of the second rod-like body 16. It is what has been.
That is, as described above, as the conventional fixture 100 such as the sheet-like material, as shown in FIG. 5, when the conventional sheet fixture 100 is embedded from above the sheet 200 into the ground 300. In addition, the sheet 200 has at least a portion through which the first rod-like body 15 as the main body passes and a hole 300 in the vicinity thereof, and a large number of large and small crack portions 301 are generated in the peripheral portion thereof. Similarly, when the pulling resistance portion 10 penetrates the sheet 200, a larger hole portion or crack portion 302 is generated.

Then, as shown in FIG. 6, after the fixing device 100 such as the sheet-like material is embedded in the sheet 200 arranged on a predetermined soft ground 300, the parts 301 and 302 and the first rod-like body 15 Arbitrary weeds 303 will be generated from the gaps formed between the spaces, that is, from the space, and as described above, a new problem arises that additional management costs are required for the removal of the weeds 303. ing.
In the present invention, it is possible to solve such problems all at once by using a fixture such as a new sheet-like article having a simple structure, inexpensive and excellent workability. It has become.

As described above, the new technical matter in the present invention is, as illustrated in FIGS. 3 and 4, fitted to the first rod-shaped body 15, and the second rod-shaped body 16. A plate-like body portion 17 configured so as to be in contact with or in the vicinity thereof is provided.
More specifically, it is preferable that the plate-like body portion 17 in the present invention is composed of an appropriate synthetic resin component, particularly in terms of durability, impact resistance, water resistance, or weather resistance. It is desirable to use excellent synthetic resin components.
Furthermore, as shown in FIG. 7, the plate-like body portion 17 in the present invention is fixedly or slidably fitted to the first rod-like body 15 which is the main body portion at a substantially central portion thereof. The hole 350 to be provided is provided.
The shape of the hole 350 provided in the plate-like body portion 17 has a cross-sectional shape that substantially matches the cross-sectional shape of the first rod-like body 15. The inner diameter can be set to be equal to or slightly larger than the diameter or maximum diameter portion of the first rod-like body 15.

That is, in the present invention, the plate-like body portion 17 is fitted to the first rod-like body 15, and the side surface of the second rod-like body 16 or the tip end portion of the first rod-like body 15. 4 are fixedly arranged so as to be in close contact with a part of 4, and the above-described holes and cracks 300, 301, 302, etc. formed in the weedproof seed 200 and the surface of the first rod-like body 15 By covering and concealing the space formed between the two, weeds 303 are used to prevent the weed 303 from being generated from that portion.

On the other hand, in the manufacturing process of the fixing device 100 such as the sheet-like material according to the present invention, the hole portion 350 of the plate-like body portion 17 is formed slightly larger than the diameter of the first rod-like body 15. In addition, setting the plate-like body portion 17 to be relatively free to slide along the first rod-like body 15 reduces the setting conditions in the manufacturing process. There is an advantage that it leads to a reduction in cost. Finally, when the plate-like body portion 17 is embedded in a predetermined place, the plate-like body portion 17 becomes a side surface of the second rod-like body 16. If it is fixedly arranged so as to be in close contact with the lower surface and a part of the tip portion 4 of the first rod-like body 15, the same effect as that obtained when it is fixed in advance can be obtained.
On the other hand, as shown in FIG. 7, the plate-like body portion 17 in the present invention has a planar shape of any one of a circle, an ellipse, a polygon including a triangle and a quadrangle. Preferably, the planar area of the plate-like body portion 17 is not particularly specified, but at least the area of the plate-like body portion 17 is determined by the pull-out resistance portion 10 being the main body portion 1. It is preferable that the shape is set to a shape having an area larger than the maximum area of the circular portion drawn when the first rod-like body 15 is rotated once around the first rod-like body 15.

Below, one specific example of the usage method of the fixing tools 100, such as a sheet-like material used on the said soft ground which concerns on this invention is demonstrated.
That is, the fixing device 100 such as the sheet-like material according to the present invention, as described above, includes the appropriate sheet-like material 200 laid on an appropriate portion of the soft ground 300 containing sand or moisture. As shown in FIG. 8, it is used for fixing on the soft ground 300, and as appropriate, the surface of the appropriate sheet-like material 200 laid on an appropriate part of the soft ground 300. A suitable hole 400 is made directly or in advance at the site of the above, and the apex portion of the second rod-shaped body 16 that is the fixing tool 100T bar portion is appropriately pushed or punched through the hole portion 400. An embedding operation is performed using an installation mechanism (not shown), and at least a part of the second rod-like body 16 that is the T-bar portion in the fixture 100 is the appropriate sheet-like material. Etc. remaining on the surface of 200 That in the manner, implanted in the ground 300.
In this case, in the case of the fixture 100 such as the sheet-like material as shown in FIG. 2C, the end portion P2 of the tip portion 4 of the first rod-like body 15 is set to be the same. Will be cast.

At this time, when the pull-out resistance portion 10 installed in the main body portion 1 descends into the ground, it is fixed in the ground after forming a considerably large crack portion 302 in a part of the sheet portion 200. .
Since a part of the nearby earth and sand will be excluded, the density of the earth and sand in the upper part of the pulling resistance part 10 that has fallen into the ground and the vicinity thereof will be considerably reduced. The pulling resistance force when the main body 1 is pulled out must be greatly reduced.

Further, when the main body portion 1 is driven into the ground, the pull-out resistance portion 10 forms an extra opening in the sheet-like material 200 or the like that is larger than the cross-sectional area of the main body portion 1. Since rainwater is submerged from the portion into the portion with reduced sediment density formed by the pull-out resistance portion 10 to enlarge the size of the portion with reduced sediment density, the pull-out resistance of the fixture Will be further reduced.

In order to confront such a problem, in the present invention, the fixture 100 embedded in the ground is used by using a rotation operation jig 150 for rotating the fixture 100 as shown in FIG. Is rotated at an appropriate angle to change the position of the extraction resistance portion 10 once disposed in the ground 300.

That is, the rotation operation jig 150 includes at least a part of the handle portion 151 that is held by an operator by hand and the second rod-like body 16 of the fixture 100 provided at an end portion of the handle portion 151. Is provided at the head of the fixture 100 that is present on the surface of the sheet-like object 200 in the slit portion 152 of the jig 150. At least a part of the second rod-like body 16 is sandwiched, and as shown in FIG. 9, the handle portion 150 is rotated by an appropriate angle, for example, 180 degrees, and shown in FIG. The positional relationship between the drawing resistance portion 10 and the bent portion F is reversed.
In the present invention, as shown in FIG. 12, instead of the handle portion 151, the second rod-like shape formed in a bifurcated manner at the tip of a rotating rod portion 51 provided with a T-bar type handle portion 50 is provided. It is also possible to use a handle portion in which a gripping rotation portion 52 in which a pair of sandwiching portions 53 and 53 for sandwiching the body 16 is formed is formed.

In the present invention, the rotation operation of the handle portion is not limited to 180 degrees, and it is needless to say that any rotation operation angle can be adopted.
During execution of the rotation operation, the earth and sand 20 in the ground can easily flow through the opening 11 provided in the pulling resistance portion 10 as shown in FIG. Therefore, the rotation operation is performed very easily, and at the same time, the pull-out resistance portion 10 avoids the portion where the sediment density is low as described above, and the ground surface having the same density as the base sediment density. Since it is fixed in the inside, the pulling resistance value by the pulling resistance portion 10 is remarkably improved, and the risk of occurrence of an unnecessary pulling state is completely prevented.

In the present invention, when the rotation operation of the handle portion is set to 180 degrees, the upper end portion of the portion where the earth and sand density formed when the pulling-out resistance portion 10 is lowered is diluted. Since the plate-like body portion 17 is covered like a lid portion, it is possible to further prevent intrusion of rainwater or the like.

Further, in order to prevent the rainwater or the like from entering the portion, an appropriate caulking material 154 may be attached to the upper surface of the periphery of the hole portion 300 of the sheet portion 200 after the rotation operation is completed. This is a desirable example.
Further, in the present invention, the plate-like body portion 17 is strong enough to completely cover the hole portions 300, 301, 302 and the like, and the hole portion is firmly fixed over a long period of time. Therefore, it is possible to completely prevent the weed 303 from being generated from the space portion.

The fixture 100 such as a sheet-like material used in the soft ground according to the present invention described above is compared with an extremely normal fixed pile (conventional example) in which the pull-out resistance portion 10 is not provided in the main body portion 1. Then, the load required for the driving operation is almost the same between the present invention and the conventional example, but the pullout resistance value is about 5 kg at the most in the conventional example, whereas the load according to the present invention is the same. In the fixture 100, the pull-out resistance value exhibits a performance well exceeding 20Kg, and the fixture 100 according to the present invention, which can be manufactured with a simple structure and at low cost, is the conventional example. It is clear that it has a remarkable effect compared to the above.

In the present invention, as shown in FIG. 1 (B), it is possible to provide a plurality of the pull-out resistance portions 10. However, while the driving load increases, the pull-out resistance value is not so high. Since it is not improved as compared with the specific example of the present invention, the specific example of the configuration in which a plurality of the pulling resistance portions 10 are provided on the surface of the main body 1 is not very advantageous.
