No. 4,538,822 (Patent Document 2) has been developed and a patent application has been filed.

  Briefly describing the reinforcing mats of Patent Documents 1 and 2, a plurality of reinforcing protrusions having a tapered shape projecting downward from the bottom surface of the laying body are arranged side by side on a flexible laying body. When this reinforcing mat is laid on the ground or a dike, a large number of reinforcing projections are immersed in the upper side of the ground or a dike, and the upper side is restrained to reinforce the ground or the dike. The effect is brought about.

  In addition, this reinforcing mat is provided with a joining margin portion without a reinforcing projection on the periphery of the laying body, and this joining margin portion is overlapped and connected to the laying body of another reinforcing mat. A size (aggregate of reinforcing mats) according to the use site can be produced.

  As a conventional connection structure between the reinforcing mats, anchor pins (deformed reinforcing bars, etc.) are formed so as to penetrate the overlapping portion from the upper side to the joint portion overlapped with the peripheral portion of the other reinforcing mat laying body. ), Or by joining seam joints on the periphery of the laying body of other reinforcing mats with a hand sewing machine or the like.

JP 2009-108660 A Japanese Patent No. 4538822

  Since the reinforcing mats such as the above-mentioned patent documents 1 and 2 are laid on the upper surface or a road is constructed after laying, an overlay load is applied, so that the laying bodies connected by the overlay load tend to be separated from each other. A force is pulled in the direction.

  Therefore, when the laying bodies of the reinforcing mat are connected to each other by driving anchor pins, the laying bodies are connected to each other by anchor pins (connected by dots). There is a concern that it tends to concentrate at the position penetrated by the pin, and this may cause breakage of the laying body.

  In addition, this reinforcing mat is made by crushed stone on the ground, etc., and is laid on this foundation, but if there is a stone with a large particle size on this foundation, anchor pins may not be driven. .

  On the other hand, when the reinforcing mats are connected by stitching, the above-mentioned problems do not occur, but the stitching operation at the site is a very troublesome task.

  The present invention seeks to solve the problems of the conventional connecting structure of such a reinforcing mat, and to solve this problem. By simply setting the laying bodies to be connected so as to be sandwiched between the peripheral portions, the laying bodies are connected to each other. It is possible to provide a laying body connector excellent in practicality that can be firmly connected to each other and is less likely to cause inconvenience such as breakage in the connected laying body.

  The gist of the present invention will be described with reference to the accompanying drawings.

  An embodiment of the present invention which is considered to be suitable will be briefly described with reference to the drawings showing the operation of the present invention.

  For example, the case where the peripheral parts of the laying body 1 are connected is demonstrated.

  When the lower surface portion of the connector main body 2 is placed on the upper surface of the peripheral portion of one laying body 1, a large number of downward piercing projections 6 provided on the lower surface portion of the connector main body 2 are scattered around the laying body 1. The lower surface of the connector body 2 is overlapped with the lower surface of the peripheral portion of the other laying body 1 on the upper surface of the periphery of the laying body 1 on which the connector body 2 is placed. When overlapped with each other, the upward piercing protrusions 4 provided in a scattered state on the upper surface of the connector main body 2 bite into the lower surface of the peripheral portion of the other laying body 1 and are locked. They are connected in a state where they are overlapped with each other via this connecting tool.

  Therefore, for example, it is possible to connect the laying bodies 1 to each other by a simple operation of simply stacking the laying bodies 1 to be connected and arranging the connecting tool between the overlapping portions (laying bodies of a desired size). 1 aggregate can be manufactured).

  Further, even if the plate-like connector main body 2 is disposed between the overlapping portions of the joints of the laying body 1, there is no inconvenience that this overlapping portion (connecting portion) becomes extremely thick and causes a large step.

  Further, the connected laying body 1 has a force that pulls in the direction in which both of them are separated from each other due to an overload or the like on the laying body 1. Since the stab-like projections 6 and the upward stab-like projections 4 are scattered and added to many places of the laying body 1, the connecting portion (overlapping portion) of the laying body 1 is broken. Hateful.

  Further, as the loading load on the laying body 1 is larger, the downward piercing protrusions 6 and the upward piercing protrusions 4 bite deeply into the laying body 1 to be locked, and the connection strength to the laying body 1 becomes higher. That is, the greater the loading load on the laying body 1, the greater the force with which the connected laying bodies 1 are pulled away from each other. However, according to the present invention, laying is performed in proportion to the increase in the loading load. Since the connection strength between the bodies 1 is also increased, the connection state between the laying bodies 1 can be maintained well without being easily released even when pulled strongly.

  Therefore, according to the present invention, the connected state of the laying bodies 1 is firmly maintained regardless of the magnitude of the upper load of the connected laying bodies 1, thereby preventing the displacement of the laying bodies 1. Will be.

  Further, for example, the upward piercing protrusion 4 and the downward piercing protrusion 6 are formed such that their protruding tips are bent back, and the upward piercing protrusion 4 and the downward piercing protrusion 6 are the laid body. In the Patent Documents 1 and 2, it is preferable to employ the fiber sheet 1A as a laying body if it is configured so as to be able to bite and engage with the fiber sheet 1A employed as 1. On the other hand, the protruding tip portions of the curved shape of the upward piercing protrusion 4 and the downward piercing protrusion 6 are easy to bite and engage. Therefore, it becomes a structure suitable for especially the connection of fiber sheets 1A like the laying body of patent document 1,2.

In addition, for example, a plurality of upper locking portions 3 having a configuration in which a plurality of upward piercing protrusions 4 are arranged in a ring shape are provided on the upper surface of the connector main body 2 in a scattered state, and the plurality of downward piercing protrusions 6 are provided. If a large number of lower locking portions 5 arranged in a ring are provided on the lower surface of the connector body 2 in a scattered state, a plurality of upward piercing protrusions 4 and downward piercing protrusions 6 arranged in a ring Will bite into the laying body 1 and lock it, and the upward piercing protrusions 4 and the downward piercing protrusions 6 arranged side by side in the ring form a connection strength that resists pulling forces from all directions. The bodies 1 can be firmly connected to each other. It should be noted that the description of “arranged in a ring” in claim 1 does not only mean that they are arranged in a ring shape, but also includes, for example, a configuration in which they are arranged in a square ring shape. It is.

  Further, for example, the upper locking portion 3 has a configuration in which a plurality of the upward piercing projections 4 are arranged in an annular shape, and the lower locking portion 5 has a plurality of the downward piercing projections 6 in an annular shape. If the connector body 2 is arranged side by side, the connection body 2 is arranged in a specific direction because there is no change in the connection strength with respect to the pulling force regardless of the orientation of the connector body 2 with respect to the laying body 1. Therefore, it is very easy to place the connecting tool and to connect the laying bodies 1 more easily.

  In addition, for example, the connector main body 2 is formed of a metal plate 2A, and by cutting and raising the connector main body 2, a plurality of the upward piercing protrusions 4 are annular along the edge of the through hole 7. A large number of the upper locking portions 3 that are cut and raised so as to be arranged side by side are provided in a scattered state, and a plurality of the downward piercing projections 6 are arranged in a ring shape along the edge of the through hole 7. If a large number of the lower locking portions 5 having a structure formed by cutting and raising are provided in a scattered state, the metal plate 2A as the connector main body 2 can be provided, for example, without attaching other parts to the connector main body 2. By performing cutting and raising by pressing, an upper locking portion 3 in which a plurality of upward piercing projections 4 are arranged in a ring shape and a lower locking portion 5 in which a plurality of downward piercing projections 6 are arranged in a ring shape. Can be integrally molded.

  Further, for example, if the upper locking portion 3 and the lower locking portion 5 are provided alternately in a predetermined direction in the connector main body 2, the connection main body 2 is limited. The upper side locking part 3 and the lower side locking part 5 by integral molding can be efficiently arranged within the range.

  Further, for example, at least the upward piercing protrusion 4 is less likely to penetrate the laying body 1 in which the upward piercing protrusion 4 bites and locks if the protruding length from the connector main body 2 is set to 5 mm or less. There is no danger of penetrating the shoe sole even if a person is placed on the joint body 2 of the joint between the laying bodies 1.

  Specific embodiments of the present invention will be described with reference to the drawings.

  In the present embodiment, a large number of upper locking portions 3 that bite and lock on the lower surface of the laying body 1 stacked on the upper surface portion are provided on the upper surface portion of the plate-shaped connector main body 2 in a scattered state. A number of lower locking portions 5 that bite into and lock the upper surface of the laying body 1 that is overlapped with the lower surface portion are provided in a scattered state on the lower surface portion of the lower surface portion 2.

  Specifically, the connector main body 2 of the present embodiment is configured by a rectangular metal plate 2A as shown in FIGS. In addition, this connector main body 2 is not limited to a rectangular shape, You may comprise with the plate-shaped body of another different shape.

  Further, the metal plate 2A has a thickness of about 0.5 mm, a long side of about 150 mm, and a short side of about 60 mm, and is configured to be small and light and easy to handle.

  The upper locking portion 3 of the present embodiment is formed by arranging a plurality of upward piercing projections 4 in an annular shape on the upper surface portion of the connector main body 2, and this annular upper locking portion 3 is connected to the connector. Many are provided in a scattered state on the upper surface of the main body 2.

  More specifically, the metal plate 2A constituting the connector main body 2 is punched (cut and raised) by a press to punch and form a regular circular through hole 7 and the edge of the through hole 7. A plurality of sharp triangular protrusions are cut and raised along the upper surface of the metal plate 2A. The plurality of sharpened projecting pieces serve as the upward piercing protrusions 4, and the plurality of upward piercing protrusions 4 constitute the upper locking portion 3 arranged side by side in an annular shape (circular shape) (see FIG. 1, see FIG.

  Further, the lower locking portion 5 of the present embodiment is formed by arranging a plurality of the downward piercing protrusions 6 in an annular shape on the lower surface portion of the connector main body 2. A large number of portions 5 are provided in a scattered state on the lower surface of the connector body 2.

  More specifically, a regular circular through hole 7 is punched and formed in the metal plate 2A by the same formation method as the upper locking portion 3, and a plurality of sharp triangular shapes are formed along the hole edge of the through hole 7. The protruding piece is cut and raised to the lower surface side of the metal plate 2A. The plurality of sharpened projecting pieces serve as the downward piercing protrusions 6, and the plurality of downward piercing protrusions 6 constitute the lower locking portion 5 arranged side by side in an annular shape (circular shape).

  Therefore, the upper locking portion 3 and the lower locking portion 5 are configured such that a plurality of upward piercing protrusions 4 and downward piercing protrusions 6 arranged in an annular shape bite into and lock the laying body 1. The upward piercing protrusions 4 and the downward piercing protrusions 6 arranged side by side in an annular shape exhibit a connection strength that resists pulling forces from all directions. In addition, since the plurality of upward stab-like projections 4 and downward stab-like projections 6 are arranged in an annular shape, the connector main body 2 can be arranged in any direction with respect to the laying body 1 (upper engagement). No matter what direction the locking part 3 and the lower locking part 5 are locked to the laying body 1), the connection strength against the pulling force does not change. Therefore, since this connecting tool has no restriction on the arrangement direction, the connecting work of the connecting tool to the laying body 1 can be performed without difficulty, and the connecting work between the laying bodies 1 is compared with the conventional connecting work. The configuration is extremely easy.

  Further, the upward piercing projection 4 of the upper locking portion 3 and the downward piercing projection 6 of the lower locking portion 5 have a projecting tip portion bowed outwardly with respect to the center of the through hole 7. It is formed in a warped shape that curves to warp.

  Accordingly, since the protruding tip portions of the upward stab protrusion 4 and the downward stab protrusion 6 have a warped shape, the fiber sheet 1A is particularly easy to bite and lock. In other words, the present embodiment is configured to be suitable for connection of the fiber sheet 1A as the laying body as in Patent Documents 1 and 2 described above.

  Further, the upward piercing protrusions 4 and the downward piercing protrusions 6 have projection lengths from the upper surface portion and the lower surface portion of the connector main body 2 set to 5 mm or less.

  Therefore, the upward piercing protrusion 4 and the downward piercing protrusion 6 having a small protrusion length are unlikely to penetrate the laying body 1 that is bitten and locked, and thus, for example, even if a person is placed on the connecting portion between the laying bodies 1, In addition, even if a person is put on the coupling tool by mistake, there is no risk of penetrating the shoe sole.

  Further, in this embodiment, as shown in FIGS. 2 and 3, the upper locking portions 3 and the lower locking portions 5 are alternately arranged in the long side direction of the connector body 2. At the same time, the upper locking portions 3 and the lower locking portions 5 are alternately arranged in the short side direction of the connector main body 2. In FIG. 2, the upper locking portion 3 is indicated by a two-dot chain line, and the lower locking portion 5 is indicated by a three-dot chain line.

  More specifically, a large number of upper locking portions 3 are provided in the inclined direction with respect to the long side and the short side of the connector main body 2, and the lower side is parallel to the parallel direction of the upper locking portions 3. By providing a large number of side locking portions 5 in a juxtaposed state, the upper locking portions 3 and the lower locking portions 5 are alternately arranged in the long side direction of the connector main body 2, and a connector The upper side locking portions 3 and the lower side locking portions 5 are alternately arranged in the short side direction of the main body 2.

  Accordingly, in the present embodiment, the upper and lower engaging portions 3 and 5 are provided on the upper and lower surfaces of the connector main body 2 as the small connector main body 2, respectively. The upper locking portion 3 and the lower locking portion 5 which are integrally formed are arranged so that the locking strength is not easily lowered and the locking strength with respect to the laying body 1 can be exerted firmly. It is composed.

  Next, the connection method of the laying body 1 using a present Example is demonstrated based on FIGS. The drawings show a case in which the laying body (thin fiber sheet 1A) of the ground reinforcing mat A of Patent Documents 1 and 2 is used as a laying body 1 and the peripheral portions of the fiber sheet 1A are connected to each other. The connector is not limited to the connection target (fiber sheet 1A) shown here, and can be used for, for example, a thick mat or other various laying objects (in short, the upward piercing protrusion 4 and (This connecting tool can be used for a laying object in which the downward piercing projection 6 can be bitten and locked.)

  As shown in FIG. 3, the joining marginal portion 8 at the periphery of one laying body 1 is connected to the upper surface of the periphery of the other laying body 1. In this case, the upper surface of the periphery of the other laying body 1 is connected. When the connector main bodies 2 of a plurality of main connectors are arranged side by side along the peripheral portion and overlapped and placed, and then the joint portion 8 of one laying body 1 is overlapped, as shown in FIG. A plurality of lower side locking portions 5 scattered on the lower surface portion of the fixture body 2 bite into and lock the upper surface of the peripheral portion of the other laying body 1 and a plurality of upper side locking portions 3 scattered on the upper surface portion of each connecting tool body 2. Bite into the lower surface of one laying body 1 peripheral part (joint joint part 8), and the peripheral parts of both laying bodies 1 are connected in a state of being overlapped with each other via a plurality of connecting tools. become.

  Although the drawing shows a case where a plurality of the connecting tools are arranged in a staggered manner around the other laying body 1, they are arranged in a straight line along the periphery of the laying body 1 periphery. May be.

  In the drawing, the long side portion of the connector main body 2 of the present connector is arranged so as to be substantially parallel to the outer edge of the laying body 1. That is, the case where this connecting tool is mounted so that the upper locking portions 3 and the lower locking portions 5 are alternately arranged in the direction in which the laying bodies 1 to be connected are about to be separated from each other is shown. However, regardless of the orientation of the connector body 2, the annular upper locking portion 3 and the lower locking portion 5 exhibit a certain connection strength against the pulling force of the laying body 1. Therefore, it is not limited to this mounting method.

  Note that the present invention is not limited to this embodiment, and the specific configuration of each component can be designed as appropriate.
