摘要： PURPOSE:To obtain a truss of a shape having a desired curvature by selectively varying the positions of mounting and length of each diagonal member of the truss in which a top chord material and a bottom chord material are connected by the diagonal members formed in short length toward end sections from centers. CONSTITUTION:A top chord material composed of a round steel pipe and a bottom chord material 2 consisting of a square pipy steel pipe are coupled by diagonal members 3, length of which is shortened toward end sections from centers. A large number of regulating holes 6 of a regulating plate 7 implanted to the bottom chord material 2 are selected properly while the length of the diagonal members 3 is selected. A bolt 8 is penetrated into the connecting hole 4 of a gusset plate 5 welded to the diagonal members 3 and the regulating hole 6, thus shaping a truss of a shape having a desired curvature.

摘要： PURPOSE:To natural turf structure replaceable for athletic field with provide a artifical turf in temporary use for the arena spaces in multi-purpose halls, roofed ball-game grounds, of athletic training places. CONSTITUTION:A shock-absorbing material 3 such as rubber sheet is placed on the corresponding floor 2 or an artificial turf athletic field by leaving a drain ditch 4. A natural turf package 5 modulated in shape and size is placed on the material 3. In the package 5, culture soil 8 is packed into a comparatively shallow box-like container 7 having drain holes 6 in the bottom and natural turf 9 is planted on the surface of the soil 8. The upper part of the side wall 7a of the container 7 is made of a shock absorber material 10 of rubber or plastics for the portion from the position smaller slightly than the cut-in depth of the spike 11a from the surface of the soil 8 to the position lower slightly than the height level of the natural turf 9.

摘要： PURPOSE:To lighten a hybrid truss by connecting a top chord material integrally transmitting bending continuously and a bottom chord material composed only of a cable by a diagonal member, forming the truss and introducing prestress to the bottom chord material. CONSTITUTION:A top chord material 1 consisting of a steel pipe, etc., and a bottom chord material 2 made up of a cable are coupled by a plurality of diagonal members 3, length of which is shortened toward the left and the right from the center of the upper and lower chord materials 1, 2. The bottom chord material 2 is pulled to the left and the right, and prestress is introduced, thus forming a hybrid truss.
