摘要： PROBLEM TO BE SOLVED: To prevent piles from increasing in number, the embedded depth of foundations and ground beams from being deepened, and concrete from increasing in quantity due to horizontal load and to reduce construction costs by increasing the horizontal load-bearing strength of piles in horizontal load-bearing piles and a method for arranging the same. SOLUTION: For bearing the pressure at the interface between a foundation 3 and earth i.e., earth pressure caused by the interaction between earth and a building by a horizontal force caused in the case that the building receives seismic load and wind load at the foundation piles of the building, a plurality of plate-shaped earth pressure plates 2 vertically protruded from the pile surfaces are provided at upper parts of the piles. in the case of a group of piles in which a plurality of horizontal load-bearing piles are arranged and in the case of two plate-shaped right and left earth pressure plates 2 vertically protruded from a pile surface at an upper part of the pile for bearing the pressure at the interface between a foundation 3 and earth i.e., earth pressure caused by the interaction between earth and a building by a horizontal force, horizontal load-bearing strength is enhanced by arranging the piles 1 in such a way that the orientation of the earth pressure plates 2 is at right angles with respect to the orientation of the adjacent pile 1.

摘要： PROBLEM TO BE SOLVED: To provide a positioning device for a rail flow grinder, capable of adjusting the position of a grinder following the meandering motion of an overhead crane, and grinding a rail flow during the operation of the overhead crane, regardless of the situation of the rail flow. SOLUTION: This device is equipped with a truck 17 moving on a travel rail 16. Also, a grinder is provided at both sides of the truck 17, and rotated for contact with the upper lateral side of the travel rail 16, thereby correcting and grinding a rail flow 81 on top of the travel rail 16. In this case, the truck 17 is provided with two such grinding wheel guide devices 22 at least at front and rear sides as having right and left guide rollers 41 and 42 respectively coming in contact with both lateral sides of the travel rail 16 via right and left arms 38 and 39 having upper parts tiltably mounted on the truck l7, and a resilient member 40 connected to the right and left arms 38 and 39 for energizing the guide rollers 41 and 42 toward the center of the travel rail 16.
