    • PROBLEM TO BE SOLVED: To provide means of easily and effectively shielding radiation at low costs.SOLUTION: Provided are a radiation shield formed from wood or a wood-derived material, a radiation shielding structure which includes the same as a constituent, and a method of shielding radiation which uses wood or a wood-derived material as a radiation shielding material. For example, when conveying or transporting a relatively large quantity of radioactive waste or the like whose radiation level exceeds a reference level, a certain amount of radiation can be shielded relatively easily at low cost by surrounding an area loaded with the radioactive waste with wood or wood-derived material. For another example, when disposing or storing a relatively large quantity of radioactive waste or the like whose radiation level exceeds a reference level, storage facilities can be built relatively easily at low cost by installing radiation shields formed from wood or wood-derived material around a disposal or storage area.
    • 要解决的问题:提供以低成本容易且有效地屏蔽辐射的方法。解决方案:提供由木材或木材衍生材料形成的辐射屏蔽,包括与其成分相同的辐射屏蔽结构,以及方法 的屏蔽辐射,其使用木材或木材衍生材料作为辐射屏蔽材料。 例如,当输送或运送辐射水平超过参考水平的相对大量的放射性废物等时,通过围绕装载有放射性废物的区域以木材或其他方式围绕放置废物的区域可以相对容易地屏蔽一定量的辐射, 木材来源的材料。 另一个例子,当放置或存放其辐射水平超过参考水平的相对大量的放射性废物等时,通过将围绕着木材或木材的材料形成的辐射屏蔽安装在低成本下可以相对容易地建造存储设施 处置或储存区域。

    • PROBLEM TO BE SOLVED: To provide a large space roof structure with a simple structure, a roof supporting structural body unit used therefor and construction methods of them capable of being applied also to a membrane roof structure on which force blowing up caused by wind acts.
      SOLUTION: The end sections of an upper main cable 1 are fixed to the upper parts of struts 5 erected so as to oppose them at an interval, a large number of vertical subsidiary cables 3 supported by the upper main cable 1 are hung down at intervals in the longitudinal direction of the upper main cable 1, a projected and curved lower main cable is opposed to the upper main cable 1 at an interval and, at the same time, the roof supporting structural body unit 6 fixes the projected and curved lower main cable 2 at a lower part of the strut 5 on a place supported by a large number of vertical subsidiary cables 3. The roof supporting structural body units 6 are provided at regular intervals, a plurality of laterally subsidiary cables are arranged and are closely connected so that the laterally subsidiary cables 4 can be crossed over the lower main cable 2 in each roof supporting structural body unit 6 and that a roof finish 10 can be held by the lower main cable 2 and each laterally subsidiary cable 4.

    • PROBLEM TO BE SOLVED: To provide means for making the most three-dimensional use of a net material, and means for easily, inexpensively and effectively improving the pressure resistance performance of the net material.SOLUTION: An approximately flat plate-like tortoise shell net material 1 is formed with approximately hexagonal networks 12 by twisting wires 11 together. A net material structure A is formed with a plurality of protruded parts 2 in which each protruded part 2 protruding forward and/or backward in a cross-sectional view in a flat plate face P is formed by bending the tortoise shell net material 1 around respective rotational axes of at least not less than three respective hinge means H1, H2 and H3 which are positioned in vicinity in approximately parallel with each other where respective twisted parts 13 (131, 132, 133) positioned on an approximately same line in a longitudinal direction are a set of the hinge means H (H1, H2, H3). Formation of the plurality of protruded parts 2 protruding from the flat plate face P of the tortoise shell net material 1 allows an effective three-dimensional use of the net material 1, and, in addition, improves bearing force to a load on the flat plate face P of the net material 1 from a reverse side of a face formed with the protruded parts 2.
