Description

本発明は、主に、建設中の構造物の外側に設置して、仮設足場や、落下防止ネットなどの取り付け枠として機能する、自走式でせり上げ移動可能な仮設ユニットに用いるブラケットに関する。 The present invention mainly relates to a bracket used for a self-propelled, liftable and movable temporary unit that is installed outside a structure under construction and functions as a mounting frame for a temporary scaffold, a fall prevention net, or the like.

自走せり上げ式仮設ユニット（以下、単に「仮設ユニット」ともいう。）とは、構造物に取り付けたブラケットに固定可能に取り付けられ、構造物に設置した牽引手段によって上方に吊り上げることで、自走でのせり上げ動作を可能にしたユニットであり、構造物の建設工事等のための作業足場や、落下防止用のネットを取り付けるための取付枠として利用されることが多い。 A self-propelled lift-up temporary unit (hereinafter, also simply referred to as a "temporary unit") is self-propelled by being fixedly attached to a bracket attached to a structure and lifted upward by a towing means installed on the structure. It is a unit that enables the lifting operation during running, and is often used as a work scaffold for construction work of structures and as a mounting frame for attaching a net for fall prevention.

この仮設ユニットの予期せぬ落下を防止するために、構造物に取り付けたブラケット側に落下防止機構を設けたものとして、以下の特許文献１に記載の発明が知られている。
特許文献１に記載の足場・養生ユニットでは、構造物に固定するブラケットに、フレーム側に設けたステーの通過する隙間の閉塞・解放が可能なレバーを設け、レバーの回転方向を規制することで、上から下へのステーの通過を防止している。 The invention described in Patent Document 1 below is known as a device in which a fall prevention mechanism is provided on a bracket side attached to a structure in order to prevent an unexpected fall of the temporary unit.
In the scaffolding / curing unit described in Patent Document 1, the bracket fixed to the structure is provided with a lever provided on the frame side capable of closing / releasing the gap through which the stay passes, and the rotation direction of the lever is regulated. , Prevents the stay from passing from top to bottom.

特許第４０５８３８３号公報Japanese Patent No. 40558383

しかし、特許文献１に記載の発明では、以下に記載する問題を有する。
（１）落下によってステーがレバーに衝突した場合、レバーの回転軸に大きな衝撃力が生じるため、回転軸の破損が懸念される。一度回転軸が破損してしまうと落下防止機能が失われてしまう。 However, the invention described in Patent Document 1 has the problems described below.
(1) When the stay collides with the lever due to dropping, a large impact force is generated on the rotating shaft of the lever, so that there is a concern that the rotating shaft may be damaged. Once the rotating shaft is damaged, the fall prevention function is lost.

そこで、本願発明は、落下防止機能をより確実に発揮することが可能な手段の提供を目的とする。 Therefore, an object of the present invention is to provide a means capable of more reliably exerting a fall prevention function.

上記課題を解決すべくなされた本願の第１発明は、構造物の壁部外側に設置する自走せり上げ式の仮設ユニットの固定に使用するブラケットであって、構造物に取り付ける、本体部と、前記本体部の先端側に設け、仮設ユニットを構成する縦材を上下動可能に収容する、収容部と、前記収容部に収容した状態の前記縦材を固定可能な、固定部と、前記本体部に対し、上下方向を回転軸方向として回転可能に取り付けられた、アーム部と、前記アーム部を一方の回転方向に付勢する、付勢体と、前記アーム部の先端に設けて、下側に傾斜面を形成してある、ゲート部と、を少なくとも具備し、前記ゲート部は、前記付勢体による付勢によって、仮設ユニットを構成する横材の通過場所を塞いでいる閉塞状態から、上昇する横材が前記傾斜面との接触によって前記付勢を超えてアーム部を他方の回転方向に回転させて前記横材の上方への通過のみを許容し、横材の通過後には前記閉塞状態に復帰して、前記横材の下方への通過を規制するよう動作することを特徴とするものである。
また、本願の第２発明は、前記第１発明において、前記傾斜面を、湾曲面で形成してあることを特徴とするものである。
また、本願の第３発明は、前記第１発明または第２発明において、前記本体部が、上下に対向配置してある、一組のフランジを少なくとも有してなり、前記アーム部が、前記フランジ間に収容される態様で取り付けられ、前記回転軸を設けた箇所において、前記フランジとアーム部の間にワッシャを介設してあることを特徴とするものである。 The first invention of the present application, which has been made to solve the above problems, is a bracket used for fixing a self-propelled lift-up type temporary unit installed on the outside of a wall portion of a structure, and has a main body portion attached to the structure. An accommodating portion provided on the tip end side of the main body portion and accommodating the vertical members constituting the temporary unit so as to be vertically movable, a fixing portion capable of fixing the vertical members accommodating in the accommodating portion, and the above. An arm portion rotatably attached to the main body portion in the vertical direction as a rotation axis direction, an urging body for urging the arm portion in one rotation direction, and an urging body provided at the tip of the arm portion. A closed state including at least a gate portion having an inclined surface formed on the lower side, and the gate portion is blocked by the urging body to block the passage place of the cross member constituting the temporary unit. Therefore, the rising cross member is allowed to pass only upward of the cross member by rotating the arm portion in the other rotation direction beyond the bias by contact with the inclined surface, and after the cross member has passed, It is characterized in that it returns to the closed state and operates so as to restrict the passage of the cross member downward.
Further, the second invention of the present application is characterized in that, in the first invention, the inclined surface is formed by a curved surface.
Further, in the third invention of the present application, in the first invention or the second invention, the main body portion has at least a set of flanges arranged vertically to face each other, and the arm portion has the flange. It is attached so as to be accommodated between them, and is characterized in that a washer is interposed between the flange and the arm portion at a position where the rotating shaft is provided.

本発明によれば、以下に記載する効果を奏する。
（１）アーム部の回転軸を上下方向としたため、アーム部の先端に設けて横材の通過箇所の解放・閉塞を担うゲート部に、上から横材が落下して衝突したとしても、回転軸の軸方向と略直交する方向に大きな衝撃力が生じにくく、回転軸の破損が生じにくい。
（２）横材が上から落下してゲート部に衝突する際に、アーム部が予期せず回転してゲート部を解放してしまうこともない。
（３）ゲート部の傾斜面を湾曲面にすることで、横材の上昇量当たりのアーム部の回転量を徐々に短くできる。したがって付勢方向とは逆方向への回転量が増加してきた際の付勢体の回転動作をより緩やかに行うことで、付勢体の破損などのおそれを抑制することができる。
（４）本体部を構成する一組のフランジ間にワッシャを介設させた状態でアーム部を回転可能に取り付けることで、アーム部とフランジとの接触によってアーム部の回転動作が滞るおそれを抑制できる。 According to the present invention, the effects described below are obtained.
(1) Since the rotation axis of the arm portion is in the vertical direction, even if the cross member falls from above and collides with the gate portion provided at the tip of the arm portion and is responsible for releasing / closing the passage portion of the cross member, it rotates. A large impact force is unlikely to be generated in a direction substantially orthogonal to the axial direction of the shaft, and damage to the rotating shaft is unlikely to occur.
(2) When the cross member falls from above and collides with the gate portion, the arm portion does not unexpectedly rotate and release the gate portion.
(3) By making the inclined surface of the gate portion a curved surface, the amount of rotation of the arm portion per rising amount of the cross member can be gradually shortened. Therefore, by performing the rotation operation of the urging body more slowly when the amount of rotation in the direction opposite to the urging direction increases, the risk of damage to the urging body can be suppressed.
(4) By rotatably attaching the arm part with a washer interposed between the set of flanges that make up the main body part, the possibility that the rotation operation of the arm part will be delayed due to contact between the arm part and the flange is suppressed. it can.

＜５．１＞ワッシャの介設
また、図２に示すように、本体部１０のフランジ１１と、アーム部４０の間の隙間にワッシャ４２を介設させておくと好ましい。これは、アーム部４０とフランジ１１との接触によってアーム部４０の回転動作が滞るおそれを抑制するためである。 <5.1> Interposition of washers As shown in FIG. 2, it is preferable that the washer 42 is interposed in the gap between the flange 11 of the main body 10 and the arm 40. This is to suppress the possibility that the rotational operation of the arm portion 40 is delayed due to the contact between the arm portion 40 and the flange 11.

＜６＞付勢体（図１）
付勢体５０は、アーム部４０の回転動作を、一方の回転方向側に付勢しておくための部材である。
付勢体５０は、弾性部材などの公知の部材を用いることができる。
本実施例では、付勢体５０を捻りコイルバネで構成し、捻りコイルバネを回転軸４１に差し込み、捻りコイルバネの一端を本体部１０と接する態様とし、他端をアーム部４０と接する態様とすることで、アーム部４０の回転動作を一方の回転方向側に付勢した状態としている。 <6> Bouncer (Fig. 1)
The urging body 50 is a member for urging the rotational operation of the arm portion 40 toward one of the rotational directions.
As the urging body 50, a known member such as an elastic member can be used.
In this embodiment, the urging body 50 is composed of a torsion coil spring, the torsion coil spring is inserted into the rotating shaft 41, one end of the torsion coil spring is in contact with the main body 10, and the other end is in contact with the arm 40. Therefore, the rotational operation of the arm portion 40 is urged to one of the rotational directions.

＜７＞ゲート部（図１）
ゲート部６０は、アーム部４０の先端に設けて、アーム部４０の回転動作によって仮設ユニットを構成する横材Ｂの通過場所の閉塞・解放を行うための部材である。

A linear inclined surface 61 is formed on one open side (hypotenuse) of the three sides constituting the lower member.

＜８＞使用イメージ（図１，図３）
図３を参照しながら、本発明に係るブラケットの使用イメージについて説明する。
図３は、アーム部４０の旋回動作を示す側面平面図である。なお、図３では、アーム部４０、ゲート部６０および横材Ｂとの関係を説明するために図示を簡略化しており、収容部２０や固定部３０を図示していない。
固定部３０による固定を解放した状態で、構造物Ｘに取り付けたチェーンブロックなどで仮設ユニットのせり上げ動作を行う場合、収容部２０に収容した縦材Ａは、そのまま上方へとスライド移動する（図１）
せり上げ動作が進んでいくと、やがて横材Ｂがゲート部６０に接触し始める（図３（ａ））。
この状態で横材Ｂが上昇し続けると、横材Ｂの傾斜面６１との当接位置が上方にスライドするように、アーム部４０の付勢方向とは逆方向にアーム部４０が回転することとなり、その結果ゲート部６０が解放して横材Ｂの通過を許容するように動作する（図３（ｂ））。
横材Ｂの通過後は、付勢体５０によってアーム部４０が前記閉塞状態へと復帰するように回転する（図１，図３（ａ））。
この閉塞状態で、仮に仮設ユニットの落下が発生しても、ゲート部６０の上方に位置する横材Ｂがやがてゲート部６０に干渉するため、落下は停止する。
また、ゲート部６０の上から横材Ｂが衝突しても、ゲート部６０は解放動作に遷移しないことから、さらなる仮設ユニットの落下が発生することはない。 <8> Usage image (Figs. 1 and 3)
An image of using the bracket according to the present invention will be described with reference to FIG.
FIG. 3 is a side plan view showing the turning operation of the arm portion 40. In FIG. 3, the illustration is simplified in order to explain the relationship between the arm portion 40, the gate portion 60, and the cross member B, and the accommodating portion 20 and the fixing portion 30 are not shown.
When the temporary unit is raised by a chain block or the like attached to the structure X in a state where the fixing by the fixing portion 30 is released, the vertical member A housed in the accommodating portion 20 slides upward as it is ( Figure 1)
As the raising operation progresses, the cross member B begins to come into contact with the gate portion 60 (FIG. 3A).
If the cross member B continues to rise in this state, the arm portion 40 rotates in the direction opposite to the urging direction of the arm portion 40 so that the contact position of the cross member B with the inclined surface 61 slides upward. As a result, the gate portion 60 is released and operates so as to allow the cross member B to pass through (FIG. 3B).
After passing through the cross member B, the urging body 50 rotates the arm portion 40 so as to return to the closed state (FIGS. 1 and 3 (a)).
Even if the temporary unit falls in this closed state, the cross member B located above the gate portion 60 will eventually interfere with the gate portion 60, so that the fall will stop.
Further, even if the cross member B collides from above the gate portion 60, the gate portion 60 does not transition to the releasing operation, so that the temporary unit does not further fall.

＜８．１＞アーム部の回転角度
なお、図３（ｂ）に示す、閉塞位置から前記横材Ｂの通過許容位置に至るまでの、アーム部４０の回転角度θは、３０°以内が好ましい。
これは、後述する付勢体５０によって一方の回転方向に付勢した状態のアーム部４０に対し、逆方向への回転角度が大きくなると、付勢体５０の破断等を引き起こす場合があるためである。
回転角度の調整は、ゲート部６０に対する回転軸４１の離隔距離でもって調整することができる。 <8.1> Rotation angle of the arm portion The rotation angle θ of the arm portion 40 from the closed position to the allowable passage position of the cross member B shown in FIG. 3B is preferably within 30 °. ..
This is because if the rotation angle in the opposite direction becomes large with respect to the arm portion 40 in a state of being urged in one rotation direction by the urging body 50 described later, the urging body 50 may break or the like. is there.
The rotation angle can be adjusted by the separation distance of the rotation shaft 41 with respect to the gate portion 60.

図４を参照しながら、本発明の第２実施例について説明する。
本発明に係るブラケットは、ゲート部６０に形成する傾斜面６１を湾曲面とすることができる。
本実施例では、傾斜面を外側にはらみ出す方向に湾曲させている。
本実施例によれば、横材Ｂの上昇量当たりのアーム部４０の回転量を徐々に短くすることができる。
すなわち、横材Ｂが傾斜面に接触する初期段階では、付勢体５０として用いる捻りコイルバネの逆方向への捻り量がまだ少なく余裕があるため、横材Ｂの僅かな上昇で、大きくアーム部４０が回転するよう構成しておき、横材Ｂが通過する最終段階では、捻りコイルバネの捻り量がすでに増加しており余裕が少なくなるため、横材Ｂの上昇量当たりのアーム部４０の回転量を小さくしてゆっくりと捻り動作を行うように機能するため、捻りコイルバネの負担を軽くして破損のおそれを抑制することができる。 A second embodiment of the present invention will be described with reference to FIG.
In the bracket according to the present invention, the inclined surface 61 formed on the gate portion 60 can be a curved surface.
In this embodiment, the inclined surface is curved in the direction of protruding outward.
According to this embodiment, the amount of rotation of the arm portion 40 per the amount of rise of the cross member B can be gradually shortened.
That is, in the initial stage when the cross member B comes into contact with the inclined surface, the amount of twisting of the torsion coil spring used as the biasing body 50 in the opposite direction is still small and there is a margin. The 40 is configured to rotate, and at the final stage through which the cross member B passes, the twist amount of the torsion coil spring has already increased and the margin is reduced, so that the rotation of the arm portion 40 per the ascending amount of the cross member B Since the amount is reduced and the twisting operation is performed slowly, the load on the twisting coil spring can be lightened and the risk of damage can be suppressed.
