摘要： PROBLEM TO BE SOLVED: To provide a hanging method for facilitating the laying of steel plates on a flat ground or slope by four-point hanging the steel plate.
SOLUTION: A hanger (a hook) 20 having a vertically movable camber 22 attached to one end face of a hanger body is locked on four hanging holes 12 formed in the steel plate. In inserting the hanger 20 in the hole 12, the camber 22 is moved upward along the hanger body, and after the hook 21 reaches the lower edge of the hole 12, the camber 22 is lowered to an initial position to engage the hook 21 with the hole 12. In order to secure a space for hanging the hook 21 between the upper and lower steel plates in carrying in and out the steel plate 10, a hole 13 for mounting a steel plate height adjusting material 30 is formed in a position at a designated distance from the hanging hole 12. Since the steel plates 10 are hoisted at four points, the steel plates can be laid on the slope according to its gradient by adjusting the length of a wire so as to improve work efficiency and since it is not necessary to lay down the steel plate toward the laying surface after lifting, it is extremely safe.

摘要： PROBLEM TO BE SOLVED: To provide a steel plate or a laying steel plate for arranging nonslipping projections on a surface.
SOLUTION: In this steel plate 10 with the nonslipping member, a flat bar 11 with a large number of nonslipping projections 12 projecting with prescribed heights from a steel plate surface 16 is welded to a position separate from respective intersections 18 on a line mutually crossing at a right angle at an oblique equal interval with the steel plate edge. An area occupied by a flat bar with four nonslipping projections on a line segment formed of adjacent crossing lines 17 is formed narrower than the tire grounding area 14 of a vehicle, and increases a nonslipping effect by surely catching a tire of a vehicle advancing and retreating from all directions.

摘要： PROBLEM TO BE SOLVED: To provide a method of easily connecting steel plates (iron plates to be laid for temporary construction).
SOLUTION: Outside holes 11 and 12 are formed in both short edges crossing one long edge and the other long edge of a steel plate 10. Tap holes 21 and 22 are formed in a lower flat bar 20, and a bolt insertion hole 31 is formed in an upper flat bar 30 at a position corresponding to the tap hole 21. When connecting the steel plates, the upper flat bar 30 is previously overlapped with the outside hole 11 near the abutment side of the steel plate edge in parallel with the steel plate edge, and a first bolt 4 is screwed to make the lower flat bar 20 cross the steel plate edge and to project the second tap hole 22 from the steel plate edge. The steel plate 10 is hoisted by a crane and set at a position adjacent to the laid steel plate 10, and thereafter, the upper flat bar 30 is turned at an angle of 90 degrees in a horizontal surface around the first bolt 41 to ride over the adjacent steel plate. The first and the second bolts 41 and 42 are fastened to pinch the steel plates by the upper and the lower flat bars 20 and 30 for connection.

摘要： PROBLEM TO BE SOLVED: To provide an earth retaining method for effectively utilizing a site area by setting up an earth retaining piles changing a cross sectional performance in the longitudinal direction near a site boundary, and utilizing an upper pile with small cross section performance to enlarge a construction of an upper part from the depth of embedment.
SOLUTION: An upper pile 12a made of H-section steel making a reference cross section or less is joined on a lower pile 12a made of H-section steel making the reference cross section of the depth D of the embedment, and the earth retaining pile 12 changing the cross section performance in the longitudinal direction is prepared. An end plate is arranged on the opposite ends of the upper and lower piles 12a and 12a, and a splice plate is fixed on flange faces of the upper and lower piles of a side receiving a side pressure. The pile 12 is set up at a position within a site area boundary B, and a horizontal lagging is fitted between the piles 12. After an underground area is excavated while an earth retaining wall is formed, an underground building frame outer layer 16 is constructed along the inner flange face of the upper pile 12b lessening the cross section performance of the lower pile.

摘要： PROBLEM TO BE SOLVED: To provide a permanent form for earth retaining and foundation, capable of easily self-standing, having no support material such as a strut and an anchor by coping with either of the case where excavation depth is shallow at the time when earth retaining is performed in foundation work (or the case where earth pressure is small) or the case where the excavation depth is deep (or the case where the rear face earth pressure is large) and performing constitution so as to freely adjust form height while embedment is stabilized particularly. SOLUTION: A projection member 6 extending in the horizontal direction toward the outside of a form is detachably or erectably mounted on right and left struts 2 and the lower part of a form panel comprising a joining material 4 provided between the struts and a panel material 5. The attaching position of the projection member 6 is adjustable in the height direction of the strut 2, and the whole form panel is constituted by an anti-corrosion raw material.
