[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a metal fitting used for covering the roots of trees planted in parks and streets.

[0002]

[Prior art]

 In order to protect the roots of trees planted in parks and streets, a tree root cover is used that is made of a great plate and covers the roots of the trees, leaving a central hole where the trees grow. The root coverings of these trees are radially divided around the center hole where the trees grow, in consideration of easy transportation and construction.

[0003] However, when these divided tree root coverings are assembled and laid at the root of the tree, the outer peripheral portion is supported by curbs, but there is no support on the side of the central hole, so that it hangs down. . Therefore, in order to connect the root coverings of the divided trees and prevent the inner edge from hanging down, connecting fittings as shown in Fig. 6 have been used.

That is, as shown in the perspective view of FIG. 6 and the assembly cross-sectional view of FIG. 7, the conventional connecting fitting 20 is pressed from below toward the center hole side of the joint 24 of the divided tree root cover 22 and is adjacent to the adjacent joint. Connecting plate 30 in which two bolts 28 that are respectively inserted into connecting holes 26 that are formed in the corners on the side of the central hole of the root cover 22 of the tree are installed, and the center hole side of the connecting plate 30. It is composed of a vertical plate 32 that is integrally connected to the end portion and hangs downward. The adjacent tree root covers 22 are connected by a bag nut 34 screwed to the tip of a bolt 28 inserted into the connection hole 26. To be done. Then, as shown in FIG. 8, the outer peripheral portion is supported by a curb 38 so that the connecting portion of the root cover 22 of the tree does not hang down, but a brick 36 or the like is provided under the vertical plate 32 of the connecting metal fitting 20. It is laid and prevents the vertical plate 32 from sinking.

[0005]

[Problems to be solved by the device]

 However, since the vertical plate 32 is hung vertically downward from the end face of the connecting plate 30 in the above-mentioned conventional metal fitting for covering the root of the tree, the langes for supporting the vertical plate 32 do not touch the ground. If it is necessary to dig and bury it, and if the tree roots are just stretched at that place, it may not be possible to bury the bricks, or the bricks may come into direct contact with the tree roots and damage the trees.

The present invention has been made in order to solve the above-mentioned problems of the conventional wood root cover connecting metal fittings, and facilitates the laying of bricks or the like for supporting the wood root covering connecting metal fittings. It is an object of the present invention to provide a connecting metal fitting for a root of a tree, in which bricks or the like do not directly contact the root of the tree and damage the tree.

[0007]

[Means for Solving the Problems]

 The metal fitting for root covering of a tree of the present invention is a connecting metal fitting on the side of the center hole of the root covering of the tree, which is divided radially around the center hole, leaving the center hole where the tree grows. The center hole side of the seam of the divided tree root coverings is supported from below, and at least two bolts are inserted into the connecting holes formed in the corners of the adjacent root coverings of the tree root coverings. The gist of the invention is that it comprises a support plate that is installed and a reinforcing plate that is integrally erected upward from the end of the support plate along the side surface of the root cover on the side of the center hole of the tree.

[0008]

[Action]

 At least two bolts, which are inserted respectively into the connecting holes drilled at the central hole side corners of the adjacent tree root coverings, are erected on the supporting plate, so that the joints of the divided tree root coverings are connected. The divided tree root cover is connected by pressing it against the center hole from the bottom, inserting bolts into the respective connection holes, and screwing a cap nut at the tip. Since the reinforcing plate is integrally erected upward from the end of the support plate along the side of the root cover of the tree on the side of the center hole, the support plate can be directly supported by bricks or the like. At that time, since bricks and the like can be buried without digging the ground so deeply, the bricks and the like cannot be buried or come into contact with the roots and damage the trees.

【Example】

 A preferred embodiment of the present invention will be described below with reference to the drawings. FIG. 1 is a perspective view of an embodiment of a connecting member for a root cover of a tree according to the present invention. The support plate 12 of the tree root cover connecting fitting 10 is large enough to cover the lower surface of the connecting hole 26 formed at the corner from the center hole side edge of the divided tree root covers 22 adjacent to each other. This is a plate having a height, and two bolts 28 that are inserted into connection holes 26 that are formed in the corners of the root cover 22 of each tree on the side of the center hole are erected.

As shown in the assembly sectional views of FIGS. 4 and 5, the end face of the base plate 12 of the base plate 12 which is located on the side of the central hole of the tree root cover 22 is covered with the tree root cover 22 when assembled to the tree root cover 22. A reinforcing plate 14 is integrally provided on the upper side so as to follow the side surface of the center hole 22.
