摘要： PROBLEM TO BE SOLVED: To provide a prevention wall for a falling stone with a cushioning mechanism having a cushioning material using wood chips at a low cost effectively utilizing lumber from a thinning. SOLUTION: The cushioning material 13 using the wood chips 11 is installed onto a surface receiving falling stones in a prevention wall body 10 for the falling stones. A bag body 12 composed of a flexible material or a housing is filled with the wood chips 11, or blocks for a cushioning obtained by molding the wood chips or compression-molding them in a hollow shape are placed singly or housed in the housing. The hollow internal surface side is reinforced by a reinforcing member. The bag body 12 or the housing is secured to the prevention wall body 10 for the falling stones by strip bodies or U bolts.

摘要： PROBLEM TO BE SOLVED: To ensure an easy, safe and firm fixable fastening by fastening a plate-like body to a wall material H type steel member and the like by means of metal fittings composed of a nut threaded with a U-shaped bolt, a plate body having a hole penetrating the bolt, and a stepped bracket fittable to the bolt. SOLUTION: A plurality of upper and lower cushion material pairs 6 are attached in parallel in the horizontal direction, to seven pieces of upper and lower all material H type steel bars 7, and the cushion materials 6 are arranged in three lines from below including a projection 60 and a recess 61. In this case, the upper recess 61 of lower side cushion material 6 is in contact with the lower projection 60 of upper side cushion material 6. Each upper and lower cussing member 6 is by half in contact with the H type steel positioned at the center between the upper and lower of wall material H type steel 7. A U-slaped bolt 2 is fixed into the mounting hole in each of the upper and lower sides of upper and lower side cushion materials 6, and they are fastened by nuts 3. Accordingly, in the case of connecting and mounting two plate-shaped bodies such as cushion materials 6 which requires the formation of recess and projection lines 61, 60 arranged alternately, the fixation and fastening can be made.

摘要： PURPOSE:To obtain a cushion for a falling rock prevention fence by constituting with a cushion body made of an expanded plastic and with an outer frame having a shape to disperse shocks and to cover the cushion body. CONSTITUTION:A cushion material 1 for a falling rock prevention fence is constituted with a cushion body 2, an outer frame 3, and a cap body 4. The cushion body 2 is made of a planar-shaped expanded material such as expanded polystyrene, expanded polyurethane, expanded concrete, expanded rubber or the like. The outer frame 3 is constituted with an upper and lower plates 5 and 6 formed with glass fiber reinforced plastics (FRP) or other plastic of equivalent physical and chemical properties. The cap body 4 is made of, like the cushion body 2, an expanded material such as expanded polystyrene, expanded polyurethane, expanded concrete, expanded rubber or the like, and is formed such that it can be inserted into paired openings 10 at opposite ends formed when the upper and lower plates 5 and 6 are combined.

摘要： PURPOSE: To disperse the impulses of falling stones sufficiently by a cushioning material for a prevention fence for the falling stones, in which pipes formed in a cylindrical shape are inserted into tires, and to prevent the damage of a prevention fence body for falling stones even in the case of the reception of the falling stones. CONSTITUTION: A cylindrical ring-shaped pipe 2a having an outer circumference slightly smaller than the inner circumference of the internal space of a used tire 1 and being made of FRPs is inserted into the opening section of the used tire 1. A main post 4 is extended in approximately the horizontal direction from foundation concrete 3, and foundation concrete 5 is placed near the bottom side of the main post 4. The base sections of supports 6, on which the front end of the main post 4 is fixed, is fastened onto foundation concrete 5, and the cushioning materials for the prevention fences for the falling stones composed of the used tires 1 and the pipes 2a are installed onto a wall material 7 on the main post 4. Accordingly, the impulses of the falling stones can be dispersed and received sufficiently.
