Abstract

PROBLEM TO BE SOLVED: To provide a simplified fence having a base (foundation) part without a protrusion toward a pedestrian side, suppressing decline in stability against toppling, and enabling a base of a conventional fence to be used as is.SOLUTION: A support enables a vertical frame material of a simplified fence having the vertical frame material with a protruded bottom edge part to be fixed at a position on a side surface of a base (foundation), instead of directly inserting into the base for fixing. The support is of a box shape that can hold a weight inside, or has a box-form weight receiving part with an opening on a bottom surface. The support further includes a cylindrical part for inserting the vertical frame material on a side surface of the weight receiving part. The base is placed inside the weight receiving part and the vertical frame material of the simplified fence is inserted into the cylindrical part, when using the simplified fence.SELECTED DRAWING: Figure 1

Description

本発明は、工事作業領域とそれ以外の領域を区切ったり、工事作業領域内においても通行可能領域と通行禁止領域を区切ったりする、移動可能な金属製または樹脂製の簡易型フェンスに関するものである。   The present invention relates to a movable metal or resin-made simple fence that separates a construction work area from other areas or separates a passable area and a no-passage area within the work work area. .

従来から、工事作業領域とそれ以外の領域を区切ったり、工事作業領域内においても通行可能領域と通行禁止領域を区切って、特定の区画領域に部外者の立ち入りを防止するための、移動可能な金属製または樹脂製の簡易型フェンスが敷設されていることがある。これら簡易型フェンスは、工事の進行に伴い区画する領域がしばしば変更されてフェンスの位置が変わることが多く、そのために設置、撤去、運搬が容易に行えるように構成されている。   Traditionally, it can be moved to separate outside construction areas from other work areas, or from inside and outside the construction work area to prevent access by outsiders. A simple fence made of simple metal or resin may be laid. These simple fences are often configured to be easily installed, removed, and transported because the area to be partitioned is often changed with the progress of construction and the position of the fence is often changed.

例えば、この用途に合う簡易型フェンスは、一対の縦枠の間にフェンス材を張った単位フェンス体を区画領域と区画外領域との境界に複数にして並べて連続フェンス体とするとともに、単位フェンス体の立ち状態を維持するおもりを兼ねたベース（基礎）を、前記連続フェンス体の両端部と隣り合う単位フェンス体の並設部とに対応する境界上の位置に配置し、そのベースに設けられた差し込み筒や差し込み孔などに単位フェンス体の縦枠の下端を差し入れた構成としている（図４や特許文献１参照）。   For example, a simple fence suitable for this application is a continuous fence body in which a plurality of unit fence bodies in which a fence material is stretched between a pair of vertical frames are arranged on the boundary between the partition area and the outside area. A base (foundation) that also serves as a weight for maintaining the standing state of the body is arranged at a position on the boundary corresponding to both end portions of the continuous fence body and the juxtaposed portion of the adjacent unit fence bodies, and is provided on the base. It is set as the structure which inserted the lower end of the vertical frame of the unit fence body in the inserted insertion tube, the insertion hole, etc. (refer FIG. 4 and patent document 1).

特開平０７−０６２８９２号公報Japanese Patent Application Laid-Open No. 07-062892

都市部において建設工事を行う場合においては、一般の通行領域が工事作業領域と近接していることが多い。例えば駅としての機能を維持しながら改修工事等を行う場合などでは、日々の工事進行状況に合わせて歩行者の安全な通路を確保することが重要であり、鉄板でできた安全鋼板などと併用して、設置、撤去、運搬の容易さから軽量の金属製または樹脂製簡易型フェンスが多用される。一般的な従来の簡易型フェンスではフェンスのベース（基礎）部分の半分が歩行者側に突出している。そのため、朝夕の混雑時間帯には歩行者が多いため、歩行者が足元を確認しないで簡易型フェンスに近接して、フェンスのベース（基礎）部分につまずくおそれがあった。   When performing construction work in urban areas, a general traffic area is often close to the work area. For example, when renovation work is performed while maintaining the function of a station, it is important to secure a safe passage for pedestrians according to the progress of daily work, and it is used in combination with safety steel plates made of iron plates. In view of the ease of installation, removal, and transportation, a lightweight metal or resin simple fence is often used. In a general conventional simplified fence, half of the base (foundation) portion of the fence protrudes toward the pedestrian side. For this reason, since there are many pedestrians in the morning and evening busy hours, there is a risk that the pedestrians may trip to the base (foundation) portion of the fence in close proximity to the simple fence without checking their feet.

一般的な従来の簡易型フェンスでは、フェンスのベース（基礎）部分の中央に単位フェンス体の縦枠の下端を差し入れるための、差し込み筒や差し込み孔が設けられている。歩行者側への突出を少なくするために、当該差し込み筒や差し込み孔をずらすだけでは、転倒に対する安定性が悪くなってしまい、ベース（基礎）自体を大きく重くしたり、他に固定できる手段がある場合などに用途が限られ運搬性や汎用性が低くなる。   In a general conventional simple type fence, an insertion tube and an insertion hole for inserting the lower end of the vertical frame of the unit fence body are provided at the center of the base (foundation) portion of the fence. In order to reduce the protrusion to the pedestrian side, simply shifting the insertion tube or insertion hole will deteriorate the stability against falling, and there is a means to make the base (base) itself heavier or to be fixed to others. In some cases, the application is limited and the transportability and versatility are reduced.

そこで本発明は上記事情に鑑み、簡易型フェンスのベース（基礎）部分の歩行者側への突出を無くすとともに、転倒に対する安定性の低下を抑え、かつ、一般の従来型フェンスのベースをそのまま活用できるようにすることを目的とするものである。   Therefore, in view of the above circumstances, the present invention eliminates the protrusion of the base (basic) part of the simple fence to the pedestrian side, suppresses a decrease in stability against falling, and uses the base of a general conventional fence as it is. The purpose is to be able to.

本発明は上記課題を考慮してなされたもので、下端部が突出した縦枠を備えた簡易型フェンスの縦枠を直接ベース（基礎）部分に差し入れて固定するのではなく、ベースの側面位置に固定することを可能にする土台である。当該土台は、おもりを入れるための箱状または底面に開口のある箱状のおもり受部があり、おもり受部側面に縦枠挿入用筒部が配置されていることを特徴とする。おもり受部にベースを入れ、縦枠挿入用筒部に簡易型フェンスの縦枠を差し入れて用いる。   The present invention has been made in consideration of the above-mentioned problems. The vertical frame of a simple fence having a vertical frame with a projecting lower end is not directly inserted into the base (base) part and fixed, but the side surface position of the base. It is the foundation that makes it possible to fix to. The base includes a box-shaped weight receiving portion having a box shape for inserting a weight or an opening on the bottom surface, and a vertical frame inserting cylinder portion is disposed on a side surface of the weight receiving portion. A base is put in the weight receiving portion, and a vertical fence vertical frame is inserted into the vertical frame inserting cylinder portion.

本発明によれば、土台本体に市販のベース（基礎）をおもりとして入れることができ、特別におもりを用意する必要がない。土台本体に対して、フェンスの縦枠を差し入れる筒部を歩行者側に配置すれば、歩行者側には土台が突出せず土台に入れたフェンスのベース（基礎）も突出しない。おもりがずれることにより、フェンスが不安定な場合には、追加のおもりを積み重ねたり、手近な別のおもりを入れるなど安定性を増すのが容易である。   According to the present invention, it is possible to put a commercially available base (base) as a weight in the base body, and it is not necessary to prepare a special weight. If the cylinder part which inserts the vertical frame of a fence with respect to a base body is arrange | positioned at the pedestrian side, a base will not protrude on the pedestrian side, and the base (foundation) of the fence put into the base will not protrude. When the fence is unstable due to the weight being displaced, it is easy to increase the stability by stacking additional weights or putting another weight at hand.
