Description

本発明は、建設工事現場などで用いる足場や支保工などの仮設構造物における安定化構造等に関し、より詳しくは、仮設構造物の設置面近傍に配置する根がらみの設置に特徴を持たせた発明に関する。 The present invention relates to a stabilized structure in a temporary structure such as a scaffold or a support used at a construction site, and more specifically, has a feature in the installation of roots to be placed near the installation surface of the temporary structure. With respect to the invention.

足場や支保工などの仮設構造物の設置面近傍には、支柱や建地材などの鉛直材を複数スパンにわたって連結する根がらみを設けることが一般的である。
根がらみは、鉛直材に生じる風荷重などの水平力を他の鉛直材に分散させる効果や、鉛直材の不等沈下を防止する効果などを有する。
根がらみは、できる限り低い位置に設置することが求められており、鉛直材との連結態様として、以下の態様が知られている。 In the vicinity of the installation surface of temporary structures such as scaffolding and timbering, it is common to provide roots that connect vertical lumber such as columns and building materials over multiple spans.
The root entanglement has the effect of dispersing the horizontal force such as the wind load generated in the vertical material to other vertical materials and the effect of preventing uneven settlement of the vertical material.
The root entanglement is required to be installed at a position as low as possible, and the following modes are known as a mode of connection with the vertical material.

［従来態様１］
図６に示すように、ジャッキベースａに取り付ける鉛直材ｂに対し、別途直交クランプｃを介して根がらみｄを取り付けたもの。
［従来態様２］
以下の特許文献１に示すように、根がらみの端部に差込み片を設け、建地側に前記差込み片の受け部を形成したもの。 [Conventional aspect 1]
As shown in FIG. 6, the vertical material b attached to the jack base a is separately attached with a root entanglement d via an orthogonal clamp c.
[Conventional aspect 2]
As shown in Patent Document 1 below, an insertion piece is provided at the end of the root, and a receiving portion of the insertion piece is formed on the building site side.

特開２００２－４７７９３号公報Japanese Unexamined Patent Publication No. 2002-47793

しかし、従来の根がらみの設置態様では、以下に記載する問題のうち、少なくとも何れか１つの問題を有する。
（１）根がらみの設置高さの低減が、鉛直材の下端近傍までに限られる。
（２）仮設構造物との接触や、地震や風などによる振動などの外部要因を受けて、ジャッキベースの回転体が自然に緩んで下方へと回転してしまったとしても、根がらみが鉛直材の高さを一定に維持しつづけるため、鉛直材と回転体との間が離れてしまい、仮設構造物の荷重がジャッキベースへと伝達されなくなってしまう。
（３）仮設構造物を仮囲いの骨組として使用するべく、鉛直材に別途パネル材などを取り付ける場合に、従来鉛直材にクランプしていた根がらみや、回転体のハンドル部分がパネル材と干渉してしまう懸念がある。 However, the conventional root-related installation mode has at least one of the problems described below.
(1) The reduction of the installation height of roots is limited to the vicinity of the lower end of the vertical material.
(2) Even if the rotating body of the jack base naturally loosens and rotates downward due to contact with a temporary structure or external factors such as vibration caused by an earthquake or wind, the roots are vertical. Since the height of the material is kept constant, the vertical material and the rotating body are separated from each other, and the load of the temporary structure cannot be transmitted to the jack base.
(3) When a panel material is attached to the vertical material separately in order to use the temporary structure as a frame of the temporary enclosure, the roots that were conventionally clamped to the vertical material and the handle part of the rotating body interfere with the panel material. There is a concern that it will be done.

そこで、本願発明は、ジャッキベースに根がらみを取り付けることが可能な手段の提供を少なくとも目的の一つとする。 Therefore, one of the objects of the present invention is to provide a means capable of attaching a root to the jack base.

上記課題を解決すべくなされた本願の第１発明は、足場や支保工などの仮設構造物の安定化構造であって、設置面と接する底部と、前記底部から上方に伸びて、仮設構造物を構成する鉛直材を取付可能なネジ棒と、前記ネジ棒に螺合して上下動可能な回転体とを少なくとも有する、複数のジャッキベースと、各ジャッキベースに取り付け可能な、連結金具と、前記連結金具を介して配置する、根がらみと、を少なくとも具備し、前記回転体は、前記回転体の側周に少なくとも一箇所以上、凹部を形成してあり、前記連結金具は、前記回転体の側周を挟みつつ、前記凹部に係合可能な、取付部と、前記取付部の背面側に設け、根がらみを把持可能な、把持部と、を少なくとも有することを特徴とする。
また、本願の第２発明は、足場や支保工などの仮設構造物における根がらみの設置方法であって、設置面と接する底部と、前記底部から上方に伸びて仮設構造物を構成する鉛直材を取付可能なネジ棒と、前記ネジ棒に螺合して上下動可能な回転体とを少なくとも有する、ジャッキベースを設置する工程と、別部材のハンドルを用いて前記回転体を螺合して、該回転体を所定の位置に調整する工程と、前記ハンドルを前記回転体から外し、前記回転体に連結金具を取り付ける工程と、複数の回転体に対し、連結金具を介して根がらみを配置する工程と、を少なくとも含み、前記回転体において、前記ハンドルの取付機構と、前記連結金具の取付機構を兼用してあることを特徴とする。

The first invention of the present application for solving the above-mentioned problems is a stabilizing structure of a temporary structure such as a scaffold or a support, and the temporary structure extends upward from the bottom portion in contact with the installation surface and the bottom portion. A plurality of jack bases having at least a screw rod to which a vertical material constituting the above can be attached and a rotating body that can be screwed into the screw rod to move up and down, and a connecting metal fitting that can be attached to each jack base. The rotating body is provided with at least one scaffolding, which is arranged via the connecting metal fitting, and the rotating body is formed with at least one recess on the side circumference of the rotating body, and the connecting metal fitting is the rotating body. It is characterized by having at least a mounting portion that can be engaged with the recess and a grip portion that is provided on the back surface side of the mounting portion and is capable of gripping the roots while sandwiching the side circumference of the mounting portion .
Further , the second invention of the present application is a method of installing a root entanglement in a temporary structure such as a scaffold or a support work, in which a bottom portion in contact with the installation surface and a vertical extending upward from the bottom portion to form the temporary structure. The process of installing a jack base having at least a screw rod to which a material can be attached and a rotating body that can be screwed into the screw rod and can move up and down, and the rotating body being screwed using a handle of another member. The step of adjusting the rotating body to a predetermined position, the step of removing the handle from the rotating body and attaching the connecting metal fitting to the rotating body, and the step of attaching the connecting metal fitting to the rotating body, and the rooting of the plurality of rotating bodies via the connecting metal fitting. It includes at least a step of arranging, and is characterized in that, in the rotating body, the mounting mechanism of the handle and the mounting mechanism of the connecting metal fitting are used in combination .

本発明によれば、以下に記載する効果のうち少なくとも何れか１つの効果を得ることができる。
（１）従来、鉛直材に取り付けていた根がらみをより低い位置に設置できるため、仮設構造物の安定化に寄与する。
（２）仮設構造物の構築後に何らかの理由で回転体が緩んで自然に回転しようとしても、連結金具によって把持される根がらみでもって当該回転動作が規制されるため、仮設構造物の構築後の回転体の位置ズレを防止することができる。その結果、回転体の位置（高さ）が保持されるため、鉛直材と回転体との接触が常に保たれることとなり、仮設構造物の荷重を確実にジャッキベースへと伝達することができる。
（３）ジャッキベースの回転体から、当該回転体の回転動作に用いるハンドルが除かれ、さらにジャッキベース自体に根がらみを取り付ける態様となったため、鉛直材に対するその他の取付部材の干渉要素が少なくなり、仮設構造物の設計の自由度が向上する。 According to the present invention, at least one of the effects described below can be obtained.
(1) Since the roots that were conventionally attached to the vertical material can be installed at a lower position, it contributes to the stabilization of the temporary structure.
(2) Even if the rotating body loosens for some reason and tries to rotate naturally after the construction of the temporary structure, the rotation operation is restricted by the roots gripped by the connecting metal fittings, so that the rotation operation is restricted after the construction of the temporary structure. It is possible to prevent the position of the rotating body from shifting. As a result, since the position (height) of the rotating body is maintained, the contact between the vertical material and the rotating body is always maintained, and the load of the temporary structure can be reliably transmitted to the jack base. ..
(3) Since the handle used for the rotating operation of the rotating body is removed from the rotating body of the jack base, and the roots are attached to the jack base itself, the interference elements of other mounting members with the vertical material are reduced. , The degree of freedom in designing temporary structures is improved.

以下、図面を参照しながら本発明の実施例について説明する。 Hereinafter, examples of the present invention will be described with reference to the drawings.

＜１＞全体構成（図１）
図１に、本発明に係る仮設構造物の構築状態を示す。
本発明に係る仮設構造物は、仮設構造物の設置面に配置するジャッキベースＡと、前記ジャッキベースＡに取り付ける連結金具Ｂと、前記連結金具Ｂを介してジャッキベースＡ間に配置する根がらみＣとを少なくとも具備してなる。
また、ジャッキベースＡには、仮設構造物を構成する建地材や支柱などの鉛直方向を長手方向とする鉛直材Ｄを上方から取り付けている。 <1> Overall configuration (Fig. 1)
FIG. 1 shows the construction state of the temporary structure according to the present invention.
The temporary structure according to the present invention includes a jack base A arranged on the installation surface of the temporary structure, a connecting metal fitting B attached to the jack base A, and a root entanglement arranged between the jack base A via the connecting metal fitting B. At least with C.
Further, a vertical material D having a vertical direction such as a building material or a support column constituting a temporary structure is attached to the jack base A from above.

＜２＞ジャッキベース（図２）
ジャッキベースＡは、仮設構造物の最下部に配置する部材である。
ジャッキベースＡは、通常、設置面に接する底部１０と、前記底部１０から上方に伸びるネジ棒２０と、前記ネジ棒２０に螺合して、前記ネジ棒２０に差し込んだ鉛直材Ｄを下から支持しながら、底部１０と鉛直材Ｄの下端との離隔距離を調整可能な回転体３０とを具備して構成する。
このうち、回転体３０の詳細について以下説明する。 <2> Jack base (Fig. 2)
The jack base A is a member arranged at the bottom of the temporary structure.
The jack base A usually has a bottom portion 10 in contact with the installation surface, a screw rod 20 extending upward from the bottom portion 10, and a vertical material D screwed into the screw rod 20 and inserted into the screw rod 20 from below. A rotating body 30 capable of adjusting the separation distance between the bottom portion 10 and the lower end of the vertical member D while supporting the bottom portion 10 is provided.
Of these, the details of the rotating body 30 will be described below.

＜３＞回転体（図２）
回転体３０は、底部１０と鉛直材Ｄの下端との離隔距離を調整するための部材である。
設置面が、傾斜地であったり、不陸が大きかったりする場合には、ジャッキベースＡの上方に設ける仮設構造物の水平を維持するべく、回転体３０の位置を調整する作業を行う。
従来の回転体３０は、ネジ棒２０上の螺合動作を行うために、側周面から張り出した持ち手部分を常設していることが一般的であるが、本発明では、前記の持ち手部分を常設せずに、任意に脱着自在可能な構成としている。
本実施例では、回転体３０の側周面に凹部３１を形成している。
この凹部３１に係止可能に構成した別部材のハンドルＥを用いて、回転体３０の螺合動作を可能とする。 <3> Rotating body (Fig. 2)
The rotating body 30 is a member for adjusting the separation distance between the bottom portion 10 and the lower end of the vertical member D.
If the installation surface is on a slope or has a large amount of unevenness, the position of the rotating body 30 is adjusted in order to maintain the levelness of the temporary structure provided above the jack base A.
The conventional rotating body 30 generally has a handle portion protruding from the side peripheral surface in order to perform a screwing operation on the screw rod 20, but in the present invention, the handle is described above. It has a structure that can be freely attached and detached without permanently installing a part.
In this embodiment, the recess 31 is formed on the side peripheral surface of the rotating body 30.
The rotating body 30 can be screwed by using the handle E of another member that can be locked in the recess 31.

＜３．１＞凹部の形態について
本発明では特に凹部３１の数や位置を限定するものではない。
なお、本実施例では、凹部３１を回転体３０の側周面において９０°ずつ間隔を空けて４箇所配置している。これは、ハンドルＥを用いた螺合動作を行う際に、適宜ハンドルＥを係止する凹部３１を入れ換えながら作業を行うことで、作業効率を向上させるためである。 <3.1> About the form of the recesses In the present invention, the number and positions of the recesses 31 are not particularly limited.
In this embodiment, the recesses 31 are arranged at four locations on the side peripheral surface of the rotating body 30 at intervals of 90 °. This is to improve the work efficiency by performing the work while appropriately replacing the recess 31 that locks the handle E when performing the screwing operation using the handle E.

＜３．２＞凹部の兼用について
前記した凹部３１は、後述する連結金具Ｂの取付にも使用可能と態様としてもよい。
したがって、凹部３１の数が多ければ多いほど、連結金具Ｂの取付位置、すなわち、回転体３０の位置に対する根がらみＣの長手方向を柔軟に設定することができることとなる。ただし、ジャッキベースＡにおいて回転体３０の一回転に対する上下動のピッチは僅かであるため、本実施例のように凹部３１を９０°ずつ４箇所設けておけば、根がらみＣの設置方向を規定したときに、ジャッキベースＡが設置面から離れてしまうなどの支障はほぼ生じない。 <3.2> Combined use of recessed portion The recessed portion 31 may be configured to be usable for mounting a connecting metal fitting B, which will be described later.
Therefore, as the number of the recesses 31 increases, the mounting position of the connecting metal fitting B, that is, the longitudinal direction of the root entanglement C with respect to the position of the rotating body 30 can be flexibly set. However, since the pitch of the vertical movement of the jack base A with respect to one rotation of the rotating body 30 is small, if the recesses 31 are provided at four locations of 90 ° each as in this embodiment, the installation direction of the root entanglement C is specified. At that time, there is almost no problem that the jack base A is separated from the installation surface.

＜４＞連結金具（図２）
連結金具Ｂは、ジャッキベースＡに取り付けることで、鉛直材Ｄよりも低い位置に根がらみＣを取り付けるための部材である。
本実施例では、連結金具Ｂは、ジャッキベースＡの回転体３０に取り付け可能な取付部４０と、根がらみＣを把持可能な把持部５０と、を有して構成する。 <4> Connecting bracket (Fig. 2)
The connecting metal fitting B is a member for attaching the root entanglement C to a position lower than the vertical material D by attaching it to the jack base A.
In this embodiment, the connecting metal fitting B includes a mounting portion 40 that can be attached to the rotating body 30 of the jack base A, and a gripping portion 50 that can grip the root entanglement C.

＜５＞取付部（図２）
取付部４０は、ジャッキベースＡの回転体３０に取り付けるための部位である。
本実施例では、取付部４０を、平面視して離隔状態で対向配置する一対の腕部４１を有する略コ字状を呈する部材で構成している。
一対の腕部４１の離隔距離は、前記した回転体３０の直径よりも大きく構成し、回転体３０の側周面を一対の腕部４１で狭むように位置させることができる。
一方の腕部４１には、内側に突出する突起４２を設け、他方の腕部４１には、内側への突出長を調整可能に螺合したボルト４３を設けている。
突起４２およびボルト４３を、前記回転体３０に設けた、略１８０°間隔を空けた二箇所の凹部３１に係合することで、回転体３０に対し、連結金具Ｂを固定することができる。 <5> Mounting part (Fig. 2)
The mounting portion 40 is a portion for mounting on the rotating body 30 of the jack base A.
In this embodiment, the mounting portion 40 is composed of a member having a substantially U-shape having a pair of arm portions 41 which are arranged so as to face each other in a plan view.
The separation distance of the pair of arm portions 41 is configured to be larger than the diameter of the rotating body 30 described above, and the side peripheral surfaces of the rotating body 30 can be positioned so as to be narrowed by the pair of arm portions 41.
One arm portion 41 is provided with a protrusion 42 protruding inward, and the other arm portion 41 is provided with a bolt 43 screwed so that the length of protrusion inward can be adjusted.
By engaging the protrusion 42 and the bolt 43 with the two recesses 31 provided in the rotating body 30 at intervals of approximately 180 °, the connecting metal fitting B can be fixed to the rotating body 30.

＜６＞把持部（図２）
把持部５０は、根がらみＣを把持するための部材である。
把持部５０は、鉛直材Ｄやネジ棒２０と略直交するように配置する根がらみＣを取り付け可能であれば、如何なる態様であってもよい、
本実施例では、把持部５０に、取付部４０の背面側に固定した単管クランプを用いている。 <6> Grip portion (Fig. 2)
The grip portion 50 is a member for gripping the root entanglement C.
The grip portion 50 may have any embodiment as long as it is possible to attach the root entanglement C arranged so as to be substantially orthogonal to the vertical material D and the screw rod 20.
In this embodiment, a single tube clamp fixed to the back surface side of the mounting portion 40 is used for the grip portion 50.

（４）根がらみの設置（図３（ｄ））
各連結金具Ｂを介して根がらみＣを取り付ける。 <7> How to use (Fig. 3)
With reference to the figure, the procedure up to the installation of the rooted C in the installation of the temporary structure will be described.
(1) Installation of jack base (Fig. 3 (a))
First, the jack bases A are arranged at predetermined intervals.
(2) Position adjustment of the rotating body (Fig. 3 (b))
The handle E is locked in the recess 31 provided in the rotating body 30 to perform a rotating operation, and the height of each rotating body 30 is adjusted.
(3) Installation of connecting bracket (Fig. 3 (c))
The rotating body 30 is removed from the handle E, the connecting metal fitting B is fitted into the recess 31 of the rotating body 30, and the bolt 43 is fastened and fixed.
(4) Installation of roots (Fig. 3 (d))
The root entanglement C is attached via each connecting metal fitting B.

＜７．１＞根がらみを利用した回転体の位置調整
なお、前記（２）の工程において、全ての回転体３０の高さを調整する必要はなく、一部の回転体３０について位置調整を行い、前記（４）の工程で前記一部の回転体３０に取り付けた根がらみＣの解放端側の位置を参考にして、その余の回転体３０の位置調整や連結金具Ｂの設置を行ってもよい。 <7.1> Position adjustment of the rotating body using roots In the step (2) above, it is not necessary to adjust the height of all the rotating bodies 30, and the position adjustment of some of the rotating bodies 30 is performed. Then, with reference to the position on the open end side of the root entanglement C attached to the partial rotating body 30 in the step (4), the position of the remaining rotating body 30 is adjusted and the connecting metal fitting B is installed. You may.

＜８＞作用・効果（図４）
図を参照しながら、本発明を適用した仮設構造物の作用効果について説明する。
（１）仮設構造物の安定化（図４（ａ））
根がらみＣを、従来の鉛直材Ｄに設置していた態様より低い位置に設置できるため、仮設構造物の安定化に寄与する。
（２）回転体３０の拘束・荷重伝達性の維持（図４（ａ））
根がらみＣは１本当たり、最低三箇所の回転体３０（ジャッキベースＡ）と連結する態様で設置される。そのため、仮設構造物との接触や、地震や風などによる振動などの外部要因を受けて回転体３０が緩んで自然に回転しようとしても、連結金具Ｂによって把持される根がらみＣでもって当該回転動作が規制されるため、仮設構造物の構築後の回転体３０の位置ズレを防止することができる。
さらに、回転体３０の位置（高さ）を保持することができるため、鉛直材Ｄと回転体３０との接触が常に保たれることとなるため、鉛直材Ｄと回転体３０とが離れてしまうことによる、仮設構造物の荷重がジャッキベースＡに伝達されない問題が生じることなく、仮設構造物全体の荷重伝達性を維持することができる。
（３）鉛直材Ｄに別部材を配置する場合の干渉防止（図４（ｂ））
仮設構造物を仮囲いとして使用するべく、鉛直材Ｄに別途パネル材などを取り付ける場合に、従来、鉛直材Ｄにクランプしていた根がらみＣや、回転体３０のハンドルＥ部分が干渉する懸念があったところ、ジャッキベースＡの回転体３０からハンドルＥが除去され、さらにジャッキベースＡに根がらみＣを取り付ける態様となったため、鉛直材Ｄに対する取付部４０材の干渉要素が少なくなり、仮設構造物の設計の自由度が向上する。 <8> Action / effect (Fig. 4)
The action and effect of the temporary structure to which the present invention is applied will be described with reference to the drawings.
(1) Stabilization of temporary structure (Fig. 4 (a))
Since the root entanglement C can be installed at a lower position than the conventional vertical material D, it contributes to the stabilization of the temporary structure.
(2) Restraint of the rotating body 30 and maintenance of load transmissibility (FIG. 4A)
The root entanglement C is installed in such a manner that it is connected to at least three rotating bodies 30 (jack base A) per one. Therefore, even if the rotating body 30 loosens due to external factors such as contact with a temporary structure or vibration due to an earthquake or wind and tries to rotate naturally, the rotation is carried out by the root entanglement C gripped by the connecting metal fitting B. Since the operation is restricted, it is possible to prevent the rotating body 30 from being displaced after the construction of the temporary structure.
Further, since the position (height) of the rotating body 30 can be maintained, the contact between the vertical material D and the rotating body 30 is always maintained, so that the vertical material D and the rotating body 30 are separated from each other. It is possible to maintain the load transferability of the entire temporary structure without causing the problem that the load of the temporary structure is not transmitted to the jack base A due to the storage.
(3) Interference prevention when another member is placed on the vertical material D (FIG. 4 (b))
When a panel material or the like is separately attached to the vertical material D in order to use the temporary structure as a temporary enclosure, there is a concern that the root entanglement C previously clamped to the vertical material D and the handle E portion of the rotating body 30 may interfere with each other. However, since the handle E was removed from the rotating body 30 of the jack base A and the rooted C was attached to the jack base A, the interference element of the attachment portion 40 with the vertical material D was reduced, and the temporary installation was performed. The degree of freedom in designing the structure is improved.

本発明に係るジャッキベースの回転体の別実施例について説明する。
図５に示すように、本実施例に係るジャッキベースＡは、回転体３０の側周面に設けた等間隔に４箇所設けた凹部３１に雌ネジ部３１１を形成し、当該雌ネジ部３１１に螺合可能な雄ネジ部６０を設けたハンドルＥを二箇所設けて、従来の回転体３０と等しい外観を構成している。
