Description

本発明はシャッター（典型的にはパネルシャッター）のパネル構造に係り、詳しくは、複数の部分から組立分解可能なパネル構造に関するものである。 The present invention relates to a panel structure of a shutter (typically a panel shutter), and more particularly to a panel structure that can be assembled and disassembled from a plurality of parts.

パネルシャッターは、複数枚のパネルを高さ方向に連結してなるシャッターカーテンによって開口部を開閉するシャッターである。各パネルの長手方向両端部にはガイドローラを有する支軸が突設されており、各パネルを支軸を介してチェーンで上下に連結し、開閉機によってチェーンを巻き上げることで、開口部上方に設けた収納部内の収納レールにパネルを順次案内して収納部にパネルを収納して開口部を開放し、開口部全閉時には、複数のパネルが上下方向に互いに密接することで開口部を閉鎖する（特許文献１参照）。 A panel shutter is a shutter that opens and closes an opening by a shutter curtain formed by connecting a plurality of panels in the height direction. Support shafts having guide rollers are projected at both ends in the longitudinal direction of each panel, and each panel is connected up and down with a chain via the support shaft, and the chain is wound up by an opening / closing machine to move above the opening. The panels are sequentially guided to the storage rails in the provided storage section, and the panels are stored in the storage section to open the opening. When the opening is fully closed, the multiple panels are brought into close contact with each other in the vertical direction to close the opening. (See Patent Document 1).

一般にパネルシャッターの各パネルは開口部全幅に延びる１枚の構造体から製作されているため、開口幅寸法が大きくなると、それだけ各パネルの幅寸法が大きくなる。このことは、パネル交換時に現場（特に建物内部の開口部を仕切る場合）へのパネル搬入が困難な場合があり得る（有効なパネル搬入経路が確保できない）、パネル重量が大きくなるため現場での作業性が悪くなる、という課題が生じることを意味する。 Generally, each panel of the panel shutter is manufactured from one structure extending over the entire width of the opening. Therefore, as the opening width dimension increases, the width dimension of each panel increases accordingly. This means that it may be difficult to bring the panel to the site (especially when partitioning the opening inside the building) when replacing the panel (an effective panel carry-in route cannot be secured), and the panel weight becomes large, so that the panel is placed at the site. This means that there is a problem that workability deteriorates.

かかる課題を解決するものとして、パネルを複数の部分に分割可能とすることが提案されている（特許文献２、３）。ここで、パネルを分割可能な構造とする場合には、パネル（特に、分割部）の強度をいかに確保するかが重要である。特に分割部には、パネル自重による垂直方向の荷重が作用するため、パネルの厚さ方向に作用する面圧に加えて、垂直荷重に耐え得る構造である必要がある。また、現場での組み立て分解作業を考慮すると、分割部を溶接（強度上は有利であるが）で組み立てることは避けるべきである。 As a solution to this problem, it has been proposed that the panel can be divided into a plurality of parts (Patent Documents 2 and 3). Here, when the panel has a structure that can be divided, it is important how to secure the strength of the panel (particularly, the divided portion). In particular, since a vertical load due to the weight of the panel itself acts on the divided portion, it is necessary to have a structure that can withstand the vertical load in addition to the surface pressure acting in the thickness direction of the panel. Also, considering the on-site assembly and disassembly work, it should be avoided to assemble the split part by welding (although it is advantageous in terms of strength).

特許文献２、３には、分割部の組み立てに溶接を用いないパネル分割構造が記載されているが、いずれも、分割部の強度（特に垂直方向の力）は、分割部を連結する螺子（ピンやボルト）に依存していることから、分割部の強度が十分であるとは言えない。 Patent Documents 2 and 3 describe a panel split structure that does not use welding for assembling the split portions, but in each case, the strength of the split portions (particularly the force in the vertical direction) is determined by the screws connecting the split portions (in particular, the force in the vertical direction). Since it depends on pins and bolts), it cannot be said that the strength of the split portion is sufficient.

また、パネルに遮音性能が要求される場合には、分割部でいかに遮音性能の低下を防止するか、という課題もある。
実公平７−４８９６０号 実開平５−７８９４号 実開平５−７３１９３号 Further, when sound insulation performance is required for the panel, there is also a problem of how to prevent deterioration of sound insulation performance at the divided portion.

本発明は、幅方向に分割された複数の分割パネルからなるパネル構造において、現場において分割パネルの組み立て・分解が可能であり、かつ、パネルに作用する力に耐え得る十分な強度を備えたパネル構造を提供することを目的とする。 According to the present invention, in a panel structure composed of a plurality of divided panels divided in the width direction, the divided panels can be assembled and disassembled in the field, and the panel has sufficient strength to withstand the force acting on the panel. The purpose is to provide a structure.
