Description

[Detailed explanation of the idea]

"Industrial Application Field" This proposal concerns road gutter covers. "Conventional technology" Road gutter covers have traditionally been made of concrete, which is not only heavy (50 kg each) and inconvenient to handle, but also has relatively low breaking strength, making it difficult to improve the appearance of the road. It was hot. ``Problems to be solved by the invention'' The purpose of this invention is to obtain a gutter cover that is lightweight, easy to handle, has relatively high breaking strength, and can improve the appearance of the road. be. ``Means for solving the problem'' This idea consists of arranging a plurality of rectangular pieces of the same length impregnated with nylon or polyester at right angles to their longitudinal direction, and bonding the abutting surfaces of the adjacent rectangular pieces with adhesive to form a rectangular plate. A gutter cover is constructed by forming a synthetic resin coating layer of the same type as the above-mentioned permeable agent on the outer surface of a rectangular plate. ``Function'' Therefore, the impregnated nylon or polyester permeates into the conduit of the square timber, bonds with the adhesive at the conduit opening, and forms a synthetic resin coating layer (nylon or polyester) of the same type as the impregnating agent (nylon or polyester). or polyester) are combined at the conduit opening, and the fiber portion, the penetrating agent and adhesive in the conduit, and the coating layer are integrated to reinforce the square timber. ``Example'' A cedar square lumber with a length and width of about 10 cm is cut into lengths of about 45 cm to form a plurality of short square pieces 2 of the same length, which are dried and finished on four sides in the length and width. Adjacent abutting surfaces of this short piece 2 are cut off, and the abutting surfaces are bonded with a synthetic resin adhesive 3 to form a rectangular plate 4. Then, the bolt 7 is inserted into the through holes 6, 6 previously drilled in the square material 2, and the bolt head 9 and the tightening nut 10 are accommodated in the recesses 8, 8 at both ends of the through holes 6, 6, respectively. 7, and close the recess 8 with a wooden stopper 11 (the through holes 6, 6, recess 8, and bolt 7 may be omitted). Thereafter, the six sides of the square plate 4 are rough-finished and a stain preventive coating is applied, and then a polyester liquid (or a nylon liquid may be used) is impregnated into the conduit. After this oozing agent 1 is cured, six surfaces are finished, and when the oozing agent 1 is polyester, a polyester liquid is applied to the finished surface.
In the case of nylon, the synthetic resin coating layer 5 is formed by overcoating with a nylon liquid (and may also be coated with a polyethylene paint containing Surfacer). In the figure, 12 indicates notches provided on both sides of the rectangular plate 4, and 13 indicates concrete road ditches. Table 1 shows a physical property test table for polyester, nylon and polyethylene.

[Table] "Effects" Since the present invention is constructed as described above, it is significantly lighter in weight compared to concrete because it is made of wood, and the fibrous material in the square timber 2 and the impregnating agent such as nylon or polyester in the conduit 1 The adhesive 3 and the coating layer 5 on the surface are bonded together for reinforcement, are highly waterproof, and are useful for improving the appearance of road gutter sections.
