Description

Technical Field

[0001] The present invention relates to improvements in a joining tool used for attaching a stone to another stone, a stone to concrete, a stone to asphalt, and a panel or the like to a stone, an anchor bolt for fixing an implement, a box or the like to a wall surface, and a road rivet, a line character rivet, a braille rivet or the like which is provided on a road for preventing traffic accidents.

Background Art

[0002] Conventionally, as a method used for joining a concrete body and stones, for instance, as shown in Fig. 24, a hole 23b is formed with a vibration drill in a concrete body 23 to be joined, an anchor 32 is set in the above hole 23b, and the anchor 32 is fixed with a driving bar. A hole 25b is formed in the upper end of a stone 25 to be joined to the above concrete body 23 and the stone 25 is fixed to a predetermined position. The interior of the above hole 25b is filled with an adhesive 26, a round pin 34 of a right joining member 31 is inserted in the said hole 25b, a left joining member 30 is set to the anchor 32 set in the above hole 25b, and a bolt 33 is temporarily fastened. The left joining member 30 and the right joining member 31 are fastened to each other by screwing a nut 11 onto the bolt 10. After the stone 25 is adjusted minutely and exactly at the predetermined position, the nut 11 is properly fastened onto the bolt 10 to be fixed. Next, after a hole 24b for allowing the pin 34 to enter is accurately formed in the lower end of a stone 24 and is filled with the adhesive 26 and then the stone 24 is put on the stone 25, strokes the same as the above are repeated to fix the stone 24. This is a conventional method.

[0003] However, in the conventional method for joining the concrete body and the stones or the like, because the formation of the hole with the vibration drill in the concrete body for driving in the anchor exerts a vibration on the wall surface of the concrete body, an influence is given to the periphery of the hole. Even if the formation is a failure, another hole can not be formed in the immediate neighborhood of the hole. Because the new hole must be distant by at least several centimeters, the hole already formed in the stone must also be moved. Besides, if the direction of the vibration drill sways right and left upon the formation of the hole in the stone with the drill, there is the case that cracks or through holes peculiar to brittle material are generated in the surface of the stone. In that case, the stone becomes impossible to use and a loss of material. Furthermore, because stone processing technique has progressed in recent years and the stone thickness has decreased to lower the cost, the progress of joining tools used for joining is slow and it is hard to obtain an economical effect.

[0004] For overcoming the above defects, the present invention aims to provide a joining tool in which processing is performed without exerting the vibration on the wall surface of the concrete body so that no influence is given to the periphery of a groove, the cracks or the through holes peculiar to brittle material are prevented from being generated in the surface of the stone, and the stone is not a loss of material, and which keeps up with the progress of stone processing technique in recent years and can be used even in the case of a thin stone thickness.

[0005] Conventionally, for fixing an electric apparatus, a storage shelf, a storage box or the like to a wall surface, an anchor bolt is driven in or an adhesive is applied to the wall surface to fix the apparatus, the box or the like.

[0006] However, in the conventional method, there are defects that, in the case of the wall surface made of hollow blocks or light concrete, even if fixing is attempted by using the conventional anchor bolt, the fixing ends in failure, and even if the electric apparatus, the storage shelf, the storage box or the like to the wall surfaces of which the adhesive is applied is fixed to the wall surface, the adhesive force of the adhesive deteriorates due to vibrations of an earthquake and so on so that the fixed electric apparatus, storage shelf, storage box or the like falls.

[0007] For overcoming the above defects, the present invention aims to provide an anchor bolt with which the electric apparatus, the storage shelf, the storage box or the like can extremely easily and simply be fixed to the wall surface of a hollow block or the wall surface of a light-concrete body, and even if there are vibrations of the earthquake and so on and the electric apparatus, the storage shelf, the storage box or the like fixed to the wall surface has been fixed to the wall surface for many years, the said electric apparatus, storage shelf, storage box or the like never falls.

[0008] Conventionally, a joining tool used for joining a stone to another stone, a stone to a concrete body or a stone to an asphalt body joins the stone to the stone, the stone to the concrete body, the stone to the asphalt body or the like by the manner that a hole is made in the stone, the concrete body, the asphalt body or the like and a bolt is embedded and fixed in the made embedding hole. However, in the case of joining a thin stone to another thin stone, if embedding holes for inserting embedded bolts are formed in both thin stones, cracks are generated in the thin stones and the thin stones break, and there is the defect that, because plural embedding holes must be made in the thin stones, too many working hours are required and the working efficiency is extremely bad and so it is not economical. Accordingly, the present invention aims to provide a joining tool for joining the thin stone to the thin stone with extreme ease.

[0009] In conventional road rivets, as shown in Fig. 47, a road rivet 53 is a rectangular parallelepiped and cylindrical fixing legs 55 for fixing on a road are attached to the lower surface of a reflection portion 53a to which a reflecting plate 54 is attached. For attaching the road rivet 53 to the road, cylindrical holes allowing the fixing legs 55 and 55 to enter are formed in the road and the fixing legs 55 and 55 are inserted in the said holes and mortar is poured into the holes to set up the road rivet. On the other hand, an adhesive is applied to the bottom surface of a road rivet and a braille rivet and they are directly bonded and fixed to the surface of a road, a sidewalk or the like.

[0010] In the method for attaching the conventional road rivet and the conventional braille rivet to the road and the sidewalk, there are many cases that a car runs up onto the road and the road rivet and the braille rivet are easily broken due to the impact by the car. Formations of embedding holes in the road and the sidewalk are extremely troublesome and the working efficiency is extremely bad and so it is not economical.

[0011] Accordingly, the present invention aims to provide a road rivet, a line character rivet and a braille rivet which can extremely simply be attached and fixed to the road and the sidewalk in a short time, and never come off even if they receive impacts, and never break besides.

[0039] Fig. 31 is a perspective front view of a joining tool that is the present invention and Fig. 32 is a perspective rear view of it. As shown in Figs. 31 and 32, the joining tool 43 that is the present invention comprises a flat member 44 and a T-shaped member 47. The flat member 44 is nearly T-shaped and comprises an anchor portion 45 and a joining portion 46. The above anchor portion 45 is semicircular and provided with plural through holes 45a, 45a, 45a, 45b, 45b, 45b and 45b made therein. The joining portion 46 formed connectedly to the anchor portion 45 is rectangular and provided with a nearly elliptic insertion hole 46a so that the T-shaped member 47 can be connected with a bolt and nut 50.

[0040] The shape of the T-shaped member 47 connected to the anchor portion 45 comprises a joining portion 48 and a standing portion 49 and an elliptic insertion hole 48a for connecting the flat member 44 is formed in the joining portion 48. Plural large and small through holes 49a, 49b and 49c are formed in the above standing portion 49. The above standing portion 49 is formed vertically to the joining portion 48. The insertion hole 46a formed in the joining portion 46 of the flat member 44 and the insertion hole 48a formed in the joining portion 48 of the T-shaped member 47 are both elliptic. But, each insertion hole 46a or 48a may be a hole that is circular, polygonal or the like. By the way, as for a method of manufacturing the T-shaped member 47, after the joining portion 48 and the standing portion 49 are formed in one flat plate, the standing portion 49 is bent at right angles to the joining portion 48 to stand up. By the construction of connectediy forming in one body as this manner, the manufacturing cost extremely decreases.

[0041] Fig. 33 is a perspective view of the state that the flat member 44 of the joining tool 43 that is the present invention is attached to and embedded in a stone, a concrete body or the like. After an adhesive is injected in an embedding groove 52a formed in a side surface of a stone 52 formed in a thin shape, the anchor portion 45 of the flat member 44 is inserted into the above embedding groove and the flat member 44 is fixed to the side surface of the board-like stone 52. For joining a stone to another stone, a stone to a concrete body or the like with the joining tool 43, as shown in Figs. 31 and 32, at first, the bolt and nut 50 screwed in the joining tool 43 is loosened to separate the flat member 44 and the T-shaped member 47 from each other.

Possibility of Industrial Utilization

[0059] Because the present invention is constructed as described above, the following effects can be obtained.

[0060] First, by cutting by using a diamond cutter, the work can be performed without giving a vibration to the concrete body side. Besides, because the depth of the groove is shallow, there is no case of touching an inside iron-reinforcing rod. In comparison with a conventional constructing method, because no anchor is driven in, it is possible to drive successively at no interval. Besides, although a pin adhered by the effect of point and line, because of the adhesion by surface, it is superior in adherence effect, and, even if there is generated a dimensional error or the like upon enforcing, it is possible easily to adjust by elongating the groove, and, because a hook can be engaged with the large-diameter hole of the insertion plate to be hung with a wire upon hanging a stone or the like, it is extremely effective for saving power. Furthermore, because the bolt is used at one place, properly fastening can be completed in one time, the slippage in setting decreases and a speedup of constructing becomes possible.

[0061] Second, an electric apparatus, a storage shelf, a storage box or the like can extremely easily and simply be fixed to the wall surface of a hollow block or the wall surface of a light-concrete body. Even if there are vibrations of the earthquake and so on and the electric apparatus, the storage shelf, the storage box or the like fixed to the wall surface has been fixed to the wall surface for many years, the said electric apparatus, storage shelf, storage box or the like never falls.

[0062] Third, in the joining tool, because the anchor portion is nearly-semicircular-plate-like, the cut groove in which the anchor portion, is inserted and embedded can easily be formed and there is no case of being easily removed from a stone or the like when being fixed to the stone or the like. Besides, even in the case that the stone or the like is an extremely-thin board-like stone, fixing is possible and the thin stone or the like never be damaged. Furthermore, because the anchor portion of the road rivet, letter rivet, braille rivet or the like that is the present invention is nearly-semicircular-plate-like, the cut groove in which the anchor portion is inserted can easily be cut, the working efficiency is remarkably good, it is economical and there is no case of being easily removed from the road due to an impact.
