Description

【０００１】
【発明の属する技術分野】
本発明は、水泳プール上屋、農業用ハウス、簡易ビニールハウスなどに好適なシートハウスに関するものである。
【０００２】
【従来の技術】
従来、この種のものにあっては、下記のようなものになっている。
鉄骨部に対して、高所作業によって縁端にハトメ穴を設けたシートを結束して張設する構造になっている。
【０００３】
【発明が解決しようとする課題】
従来の技術で述べたものにあっては、下記のような問題点を有していた。
１．シート展張時に高所作業となり、危険である。
２．シート展張作業が高所作業となってしまうため、労働安全衛生規則に基づき作業床を設置しなければならず、そのため、費用が嵩む。
３．従来のシートを止め付ける方法のシート周囲に取付けられたハトメを利用して骨組鉄骨とロープで固定する方法では、高所作業を伴う上、作業時間もかかり、シートの充分な緊迫状況が得られなかった。
４．従来のレール（特許第２５３４９６９号、意匠第９６１２８４号のレール）は、レール自体の剛性がなく、また、シートとのクリアランスがないため、下地の鉄骨の精度が悪ければレールも左右されやすく、結果、シートのスライドが容易でなかった。
【０００４】
