摘要： PROBLEM TO BE SOLVED: To easily and surely install a grating by providing a gap-stopper to be engaged with an inner side of a gutter along a contact surface, or by fixing a pipe or an elastic material to the contact part. SOLUTION: A grating 1 is formed into a square, and two steel pipes 2 are welded in parallel to two sides of a lower side 1a so as to correspond to a receiving part 21 of a gutter 20. The section of the pipes 2 is approximately fan-shaped, and the pipes are directed downwardly in the outer direction. A gap-stopper 4 is welded to an inner side X of the pipes 2 so as to be suspended, and provided at the position so as to be engaged with an inner side 22 of the gutter 20. Fine adjustment in positioning is unnecessary, and the grating can be easily installed, and close attachability of the contact surface can be improved.

摘要： PURPOSE:To remove the garbage pulverized finely by a crusher from waste water and to make the waste water clean by housing a basket detachably below an inlet in the main body, forming a filter medium by joining plural pebbles with resin and furnishing the medium detachably below the basket. CONSTITUTION:Most of the finely pulverized garbage is removed from waste water by a basket 40, the waste water with most of the garbage removed is then filtered by a filter medium 50, and the waste water is discharged from an outlet 30 as clean water. In this case, since the medium 50 is formed by joining plural pebbles with resin, the filtration surface area is increased, and the filtration capacity is enlarged. As a result, the garbage not removed by the basket 40 is decomposed, for example, by the bacterial generated in the medium 50 and surely removed, and the waste water is made cleaner.

摘要： PROBLEM TO BE SOLVED: To provide a bracket installed to a gutter block, manhole or other gutter-shaped structure as a single body and its manufacturing method which permits the production in a short period of time at a low cost by omitting the metal plating process and also improves the yield of bracket products by enhancing the accuracy of the shape required for the bracket. SOLUTION: The bracket 10 is constituted by jointing steel members and also for jointing work, a corrosion resisting process is applied to the surface of the steel members in advance. The corrosion resisting process is performed by hot dipping, a layer by the hot dipping mainly contains zinc and very small amounts of aluminum and magnesium in their composition; and it is desired to have 5.5 to 6.5 weight % of aluminum and 2.5 to 3.5 weight % of magnesium.

摘要： PROBLEM TO BE SOLVED: To prevent the slipping of motor vehicles or people on a channel block by coupling, at a low cost and with a high strength, receiving frames with coupling members embedded in concrete forming channel blocks and arranging non-slip members between corners angles attached to the blocks and at both the sides of each channel lid. SOLUTION: A corner angle 11 comprising a steel member equipped with a channel lid placing portion 12 is arranged corresponding to the width of channel lid placed, and a non-slip member 14 made of checkered steel plates is placed between the corner angles 11 at both the side of gutter lids. On the other hand, four coupling members 13 made of deformed round steel bars are welded and jointed between the corner angles 11. By doing this, a receiving frame 10 is fixed to a formwork and, even fresh concrete is poured, no concrete surface is formed at the road surface side of the channel block 100. Thus, the groove lid and non-slip member 14 are connected alternately and, even a motor vehicle actuates the brake on the channel block 100, no difference in the effects of right and left brakes occurs and thus any danger by slip can be prevented.

摘要： PURPOSE: To easily operate, simplify tools and devices, and the like used for manufacture, restrain consumption of consumable goods so as to reduce running cost, and prevent generation of chip on the cutting section, in manufacturing a ditch cover. CONSTITUTION: In a cutting tool 11 for cutting off the end part of a bar 4 used for structural material as a surplus part 4a, it is formed into a nearly pipe-like shape, and the size of the end face opening of the pipe-like tool is formed so that it can be freely inserted to the surplus part 4a and play at inserting is small. When the cutting tool 11 is inserted to the surplus part 4a, the length of the tool is set so that the surplus part 4a can be bent by lever action while setting the end part on the inserting part side of the cutting tool 11 as the fulcrum and the other end as the point of force, and the mechanical strength of the tool is set so as to serve as the lever bending the surplus part 4a.

摘要： PURPOSE:To cover the decrease in the effect of the antiskidding caused by the abrasion of projections by arranging a large number of projections forming absorption recesses in the central parts of them on the upper surface of a gutter cover. CONSTITUTION:Plane rhombic projections 10 are arranged on the upper surface of an I-shape steel 1 at specific intervals. At that time, plane rhombic recesses 11 with the same shape for absorption are provided to the central parts of the projections 10. The bottoms of the recesses 11 are so formed that they must be flushed with the upper surface of the I-shape steel 1. Accordingly, when a tire is contacted with the projections 10, the resistance occurs to make it as antiskidding. In the case the tire passes the recesses 11, air in the recesses 11 is exhausted by pushing the tire and, at the same time, the surface rubber of the tire is so operated that it is absorbed in the recesses 11. According to the constitution, the effect of antiskidding can be displayed for a long period of time.
