Description

本発明は、工事現場等で用いられる足場に張られ、足場を覆う足場用シートに関する。   The present invention relates to a scaffold sheet that is stretched on a scaffold used at a construction site or the like and covers the scaffold.

建物の建設、建物の外壁改修工事等においては、仮設の足場を組み立てて高所の作業を行う。この足場には、建材や工具が足場の外に落下することを防止するためのシートが足場の、建物と反対側の側面全体に張られている。下記特許文献１には足場用シートの例が示されている。   In building construction and building outer wall renovation work, temporary scaffolds are assembled to work at high places. In this scaffold, a sheet for preventing building materials and tools from falling outside the scaffold is stretched over the entire side of the scaffold opposite to the building. Patent Document 1 below shows an example of a scaffolding sheet.

特開２００９−１５５８５２号公報JP 2009-155852 A

既存の建物の外壁工事の際、当該建物に引き込まれる電力線等の既設の構造物が、足場用シートを張る際に妨げになる場合がある。このような既存構造物を避けるように足場用シートを張ると、既存構造物の周辺にシートが張られていない開放部分ができるという問題があった。   When constructing an outer wall of an existing building, an existing structure such as a power line drawn into the building may become an obstacle when the scaffolding sheet is stretched. When the scaffolding sheet is stretched so as to avoid such an existing structure, there is a problem that an open portion where the sheet is not stretched is formed around the existing structure.

本発明は、既存構造物の周囲に開放部分ができないようにする足場用シートを提供することを目的とする。   An object of the present invention is to provide a scaffold sheet that prevents an open portion from being formed around an existing structure.

本発明の足場用シートには、当該シートの周縁から内側に向けて延びる切り込みが設けられ、この切り込みには、当該切り込みを閉じることが可能なスライドファスナが設けられている。電力線等の既存構造物がこの切り込みを通って、当該足場用シートの表裏を貫くようにし、スライドファスナにより、この既存構造物の両側の切り込みを閉じる。 The scaffold sheet of the present invention is provided with a cut extending inward from the periphery of the sheet, and the cut is provided with a slide fastener capable of closing the cut. An existing structure such as a power line passes through the cut and penetrates the front and back of the scaffolding sheet, and the cuts on both sides of the existing structure are closed by slide fasteners.

既存構造物の両側の切り込みをファスナで閉じるようにしたことにより、既存構造物周囲の足場用シートの開放部分をなくすことができる。   By closing the cuts on both sides of the existing structure with fasteners, it is possible to eliminate the open portion of the scaffolding sheet around the existing structure.

以下、本発明の実施形態を、図面に従って説明する。図１は、本実施形態の足場用シート１０の全体構成を示す図である。足場用シート１０は、網目を有する網地１２と、網地１２の周縁に網地１２より強度の高い枠材１４が接着、縫製等の手段により固着されている。枠材１４には、足場用シートの周縁に沿ってはとめ１６が配列されている。はとめ１６にロープや針金を通し、足場の棒材にこれを結びことにより、足場に当該足場用シート１０が張られる。   Hereinafter, embodiments of the present invention will be described with reference to the drawings. FIG. 1 is a diagram illustrating an overall configuration of a scaffold sheet 10 according to the present embodiment. The scaffold sheet 10 has a mesh 12 having a mesh, and a frame member 14 having a higher strength than the mesh 12 is fixed to the periphery of the mesh 12 by means such as adhesion and sewing. On the frame member 14, fits 16 are arranged along the periphery of the scaffold sheet. By passing a rope or wire through the barb 16 and tying it to a bar of the scaffold, the scaffold sheet 10 is stretched on the scaffold.

足場用シート１０は長方形の外形を有し、長方形の少なくとも１辺に切り込み１８を有している。特に、切り込み１８は、長方形の長辺に設けられることができる。また、辺の中点に設けることも、また中点ではない、他の位置に設けることもできる。切り込み１８には、スライドファスナ２０が設けられている。   The scaffold sheet 10 has a rectangular outer shape, and has a cut 18 on at least one side of the rectangle. In particular, the cut 18 can be provided on the long side of the rectangle. Further, it can be provided at the midpoint of the side, or at another position other than the midpoint. The notch 18 is provided with a slide fastener 20.

図２は、足場用シート１０の切り込み１８周囲の詳細な構成を示す図である。図２において、スライドファスナ２０は、完全に開いた状態で示されている。スライドファスナ２０は、切り込みに両側の辺縁にそれぞれ設けられたファスナエレメント２２，２４と、２個のスライダ２６，２８を有する。ファスナエレメント２２，２４は、よく知られているように、細かい突起が配列されたものであり、対向するエレメントの突起が互いに噛み合って切り込みを閉じ合わせる。図２においては、簡略のために、この配列された突起を省略して表している。   FIG. 2 is a diagram illustrating a detailed configuration around the cut 18 of the scaffold sheet 10. In FIG. 2, the slide fastener 20 is shown fully open. The slide fastener 20 has fastener elements 22 and 24 provided on both sides of the cut and two sliders 26 and 28, respectively. As is well known, the fastener elements 22 and 24 are arranged with fine protrusions, and the protrusions of the opposing elements mesh with each other to close the cut. In FIG. 2, the arranged protrusions are omitted for simplicity.

スライドファスナ２０は、頭合わせ型のファスナであり、二つのスライダ２６，２８を有する。切り込み１８の開放口側（足場シートの周縁側）のスライダ２６は、開き型スライダであり、ファスナエレメント２２，２４の端において一方のファスナエレメント２２から外れて、切り込み１８を開くことを可能としている。もう一つのスライダ２８は、ファスナエレメント２２，２４の端において、両側のエレメントから外れない、止めタイプのスライダである。頭合わせ型のファスナは、二つのスライダ２６，２８の間において、ファスナエレメント２２，２４の噛み合いが解除される。一方で、図１に示すように、二つのスライダ２６，２８が当接しているときには、ファスナ全体が閉じ合わされている。   The slide fastener 20 is a head-to-head fastener and has two sliders 26 and 28. The slider 26 on the opening side of the notch 18 (periphery side of the scaffolding sheet) is an open-type slider, and is disengaged from one fastener element 22 at the end of the fastener elements 22, 24 to allow the notch 18 to be opened. . Another slider 28 is a stop-type slider that does not come off from the elements on both sides at the ends of the fastener elements 22 and 24. In the head-matching type fastener, the engagement of the fastener elements 22 and 24 between the two sliders 26 and 28 is released. On the other hand, as shown in FIG. 1, when the two sliders 26 and 28 are in contact, the entire fastener is closed.

図３は、電力の引込み配線（以下、電力線と記す。）３０が、足場用シートを貫通するときの状態を示す図である。足場用シートは、その辺縁に設けられたはとめ１６を用いて、足場に結び付けられるため、足場の棒材と位置関係が固定される。電力線３０が既設の場合、足場用シートを電力線３０が干渉し、足場用シートを張ることができず、開放した部分が生じる。足場用シートの、このような開放した部分は、ここから建材や工具などが、足場の外に落下する可能性があり、好ましくない。そこで、足場用シート１０の切り込み１８に電力線３０を通し、二つのスライダ２６，２８を電力線３０の近傍までスライドさせ、電力線３０を挟むようにする（図３参照）。これにより、電力線３０は足場用シート１０の表裏を貫いて延び、電力線３０の両側のファスナエレメント２２，２４は閉じ合わせられ、足場用シートの開放部分がない状態となる。   FIG. 3 is a diagram showing a state when a power lead-in wiring (hereinafter referred to as a power line) 30 penetrates the scaffolding sheet. Since the scaffold sheet is tied to the scaffold using the fittings 16 provided at the edge thereof, the positional relationship with the scaffold bar is fixed. In the case where the power line 30 is already installed, the power line 30 interferes with the scaffold sheet, and the scaffold sheet cannot be stretched, resulting in an open part. Such an open part of the scaffolding sheet is not preferable because building materials, tools, and the like may fall out of the scaffolding from here. Therefore, the power line 30 is passed through the notch 18 of the scaffold sheet 10 and the two sliders 26 and 28 are slid to the vicinity of the power line 30 so as to sandwich the power line 30 (see FIG. 3). Thereby, the power line 30 extends through the front and back of the scaffolding sheet 10, the fastener elements 22 and 24 on both sides of the power line 30 are closed, and there is no open part of the scaffolding sheet.

また、スライドファスナに替えて、面ファスナ等を用いて、電力線の両側の切り込みを閉じ合わせるようにすることもできる。   Moreover, it is also possible to close the cuts on both sides of the power line by using a hook-and-loop fastener or the like instead of the slide fastener.

１０ 足場用シート、１８ 切り込み、２０ スライドファスナ、２２，２４ ファスナエレメント、２６，２８ スライダ、３０ 電力線（貫通部材）。   10 Scaffolding sheet, 18 notches, 20 slide fasteners, 22, 24 fastener elements, 26, 28 sliders, 30 power lines (penetrating members).
