摘要： PURPOSE:To provide a lightweight shading without requiring any special storing space and to facilitate switching of light transmission and light shade. CONSTITUTION:A shading device 10C equipped with at least one fixed panel and one turning panel is mounted under a roof truss body of a building roofed with roofing having light transmission efficiency, and a first polarizing sheet ps1 and a second polarizing sheet ps2 are mounted k the fixed panel 11. The second polarizing sheet ps2 and the first polarizing sheet ps1 are also mounted in the turning panel 12. The turning panel 12 is turned to parallel deflection axis of the first and second polarized sheets of the fixed panel with deflection axis of the first and second polarized sheets of the turning panel, and light can be transmitted. The turning panel is turned, the deflection axis of the first and second polarized sheets of the fixed panel and the deflection axis of the first and second polarized sheets of the tuning panel are positioned each other at 90 deg., and light can not be transmitted. Accordingly, a shading is used for ceiling, and a driving means of the turning panel can be miniaturized.

摘要： PURPOSE:To obtain a replaceable artificial turf structure for athletic field with natural turf for temporary use in multi-purpose places such as sports ground for soccer, golf, or other gathering or displaying places, using natural turf. CONSTITUTION:On a corresponding position of an athletic field 2 with natural turf 1, a drawable, small, long rectangular natural turf package 5 is set in parallel with an interval equal to the span of the legs 4 of a steel-framed base 3. The legs 4 of the base 3 are erected on the place where the packages 5 are drawn out, and artificial turf 6 is placed on the base 3. The athletic field 2 with natural turf 1 can thus be comparatively simply changed into a place with artificial turf for temperary use in sports or events where natural turf is not suited. The field 2 can thus be more expanded to versatile uses.

摘要： PURPOSE:To unify shapes and dimensions of panels as many as possible to rationalize production by expanding and dividing a thinned-out radial cable into two in a nonfixation state with respect to film materials to expand, and fixing next adjacent radial cables to parts intersecting with concentric circle cables. CONSTITUTION:When air film structure cables composed of concentric circle cable b' and radial cables a' are arranged, the radial cables a' are thinned out at the central part of them, and cable divisions of the central part are proper divisions. The thinned-out radial cables a' are divided into two expansion cables d to d to expand, and they are fixed to parts where next adjacent radial cables a or a' are intersected with the concentric circle cables b. Stress treatment in terminals of the cables a' is smoothly made, and excessive concentrated stress does not also impose on film stress.

摘要： PURPOSE: To assure safety in construction by extending posts after installing posts, ring cables, diagonal cables to a ridge cable erected between a center ring and a compression ring at the outer periphery. CONSTITUTION: Many ridge cables 3 are loosely erected radially between a center ring 1 and a compression ring 2 at the outer periphery. And post 4a, 4b with the length decreased are attaached at the predetermined position of each ridge cable 3 located with equidistance from the center of the center ring 1, after attaching a ring cable 6 to the bottom end of the post, a diagonal cable 7 is adjusted to a predetermined length. Next, subsequently to the post 4a at the outer side, the inner side posts 4b are sequentially extended, the ridge cable 3 is raised, and the position of the center ring 1 is raised to the highest position. In this way, the term of construction work can be reduced.
