Description

本発明は、建設現場で使用される作業現場用の梯子や仮設作業台などの支柱として好適な簡易型の仮設用支柱に関する。 The present invention relates to a simple temporary support column suitable as a support column for a work site used at a construction site or a temporary work table.

建設中の柱の上部にプレキャストコンクリート梁（ＰＣ梁という）を設置する場合などには、柱の上部に露出した露出鉄筋の外側の狭い空間に作業者が上がって重機の操縦者に指示を出しながら作業を行うといった作業形態が従来から広く行われている。しかしながら、この作業形態は作業性がよくないばかりでなく、危険性も少なくないといった問題があった。そこで、柱の側面部に立て掛けて上部を露出鉄筋に掛止することにより転倒を防止した作業台付きの梯子も開示されている（特許文献１参照）。しかしながら、この作業台付梯子は、柱の側面部に立て掛けて使用するため、柱の側面で支えるサポートやＰＣ梁を設置する側面と競合する場合には支障が生じるという問題があった。また、スラブ面上に設置するため、スラブ面の有効利用や作業の妨げにもなるといった問題もあった。他方、建設中の柱の露出鉄筋を利用して吊設し得るように構成した作業用足場も従来から知られている（特許文献２参照）。しかしながら、この従来の作業用足場では、柱の側面の平面部分に足場を吊設する支持形態が採用されていたため、横方向の振れを防止するには、横方向の幅をある程度大きくして複数本の露出鉄筋により支持するといった、大がかりな構造を採用する必要があった。このため、重量も大きくなり、運搬や吊設作業にも大きな作業負担がかかるといった問題があった。また、柱の側面部に設置されることから、柱の側面で支えるサポートやＰＣ梁を設置する側面と競合する場合には支障が生じるという同様の問題があった。さらに、梯子としての機能を付加することは技術的に困難であった。
特開２００１−１８２４６５号公報特開平７−１８０３４５号公報 When a precast concrete beam (PC beam) is installed on the upper part of the pillar under construction, the worker goes up into a narrow space outside the exposed reinforcing bar exposed at the upper part of the pillar and gives instructions to the operator of the heavy machinery. However, work forms such as performing work have been widely performed. However, this work form has a problem that not only the workability is not good but also the danger is not small. Therefore, a ladder with a work table that is prevented from falling by leaning on the side surface of the pillar and hooking the upper part to the exposed reinforcing bar is also disclosed (see Patent Document 1). However, since this ladder with a work table is used by leaning on the side surface of the column, there is a problem that a problem arises when competing with the side surface on which the support or PC beam is supported by the side surface of the column. In addition, since it is installed on the slab surface, there is a problem that the slab surface is effectively used and the work is hindered. On the other hand, a working scaffold configured so as to be able to be hung using an exposed reinforcing bar of a column under construction is also conventionally known (see Patent Document 2). However, in this conventional work scaffold, a support form in which the scaffold is suspended from the flat portion of the side surface of the column has been adopted. Therefore, in order to prevent lateral runout, the lateral width is increased to some extent, and a plurality of scaffolds are suspended. It was necessary to adopt a large-scale structure that was supported by the exposed steel bars of the book. For this reason, there is a problem that the weight is increased and a large work load is applied to transportation and suspension work. In addition, since it is installed on the side surface of the column, there is a similar problem that a problem arises when competing with the side supported by the side of the column or the side where the PC beam is installed. Furthermore, it was technically difficult to add a function as a ladder.

以下、図面に基づいて実施例に関して説明する。図１は本発明に係る仮設用支柱を作業現場用の梯子に適用した第１実施例の使用状態を例示した使用状態説明図であり、図２はその部分拡大平面図である。図中、１は仮設用支柱であり、本実施例では角形パイプからなる軸体２を使用し、その上部に柱３の適宜の角部４の近傍に露出した露出鉄筋５に掛止可能な掛止部６を備えるとともに、軸体２の適宜位置、本実施例では上下の２個所に柱３の角部４に係合可能な角部係合部７，８を備えている。また図２に示したように、軸体２の両側には所定間隔を置いて足掛け部材９，１０を付設し、これにより作業現場用の梯子１１を形成している。 Embodiments will be described below with reference to the drawings. FIG. 1 is a use state explanatory diagram illustrating a use state of a first embodiment in which a temporary support column according to the present invention is applied to a ladder for a work site, and FIG. 2 is a partially enlarged plan view thereof. In the figure, reference numeral 1 denotes a temporary support column. In this embodiment, a shaft body 2 made of a square pipe is used, and can be hooked on an exposed reinforcing bar 5 exposed in the vicinity of an appropriate corner portion 4 of the column 3 at the upper portion thereof. In addition to the latching portion 6, corner portion engaging portions 7 and 8 that can engage with the corner portion 4 of the column 3 are provided at appropriate positions of the shaft body 2, in the present embodiment, at two locations on the top and bottom. As shown in FIG. 2, leg members 9 and 10 are attached to both sides of the shaft body 2 at a predetermined interval, thereby forming a ladder 11 for a work site.

そして、使用に際しては、本実施例に係る梯子１１を持上げて下から前記掛止部６を露出鉄筋５に掛止し、角部係合部７，８を柱３の対象の角部４に係合させた上、足掛け部材９，１０上に乗って掛止部６と軸体２との間隔の調整や、掛止部６に外れ防止手段のある場合にはそのための作業を行うことにより、簡便に吊設することができる。なお、この場合、掛止部６と軸体２との間隔の調整作業においては、作業者が足掛け部材９，１０上に乗り、体重が負荷された状態で行われるので、締めすぎにより角部係合部７，８が柱３の角部４から浮いたりすることは防止される。他の設置位置へ移動する際には、場合に応じて外れ防止手段を解除した後、下方から掛止部６を露出鉄筋５から外したり、あるいは他の角部４に設置した別の梯子に上がって掛止部６を露出鉄筋５から外すことにより、簡便に移動することができる。 In use, the ladder 11 according to the present embodiment is lifted, and the latching portion 6 is latched to the exposed reinforcing bar 5 from below, and the corner engaging portions 7 and 8 are attached to the corner 4 of the target of the column 3. After engaging, adjust the distance between the latching portion 6 and the shaft body 2 by riding on the footrest members 9, 10, and if the latching portion 6 has a disengagement prevention means, work for it It can be easily suspended. In this case, the adjustment work for the distance between the latching portion 6 and the shaft body 2 is performed in a state where the operator rides on the legrest members 9 and 10 and the weight is loaded. The engaging portions 7 and 8 are prevented from floating from the corner portion 4 of the column 3. When moving to another installation position, after releasing the disengagement prevention means depending on the case, the latching part 6 is removed from the exposed reinforcing bar 5 from below, or another ladder installed at the other corner part 4 is used. By moving up and removing the latching portion 6 from the exposed reinforcing bar 5, it can be moved easily.

次に前記仮設用支柱１の各部分に関して詳細に説明する。図３は仮設用支柱１の上方部分を示した側面図、図４はその平面図、図５は前記上方部分の正面図である。図示のように、軸体２の上部側面には、円筒状支持部材１２を溶接等により固着し、その円筒状支持部材１２の内方に連結ボルト１３を挿通して回転可能な状態に支持するように構成している。図６は前記掛止部６を拡大して示した側面図、図７はその正面図であり、図示のように、本実施例に係る掛止部６は、板材を断面Ｕ字状に屈曲したものから構成される。この掛止部６には、露出鉄筋５に係合し得るフック部１４が形成されているとともに、断面Ｕ字状の内部にはナット等からなる雌ねじ部材１５が溶接等により固着され、この雌ねじ部材１５に前記連結ボルト１３が螺入されている。しかして、雌ねじ部材１５に螺入された連結ボルト１３を回転して掛止部６と軸体２との間隔を調整することにより、露出鉄筋５に対するフック部１４の係合状態をより的確なものとすることができる。なお、図中、１６は連結ボルト１３に設けられた抜け止用の係止板である。 Next, each part of the temporary support column 1 will be described in detail. 3 is a side view showing an upper portion of the temporary support column 1, FIG. 4 is a plan view thereof, and FIG. 5 is a front view of the upper portion. As shown in the figure, a cylindrical support member 12 is fixed to the upper side surface of the shaft body 2 by welding or the like, and a connecting bolt 13 is inserted inside the cylindrical support member 12 to support it in a rotatable state.

It is comprised from the channel-shaped connection member 20 connected. That is, the upper receiving member 17 is fixed to the front surface portion of the shaft body 2 below the cylindrical support member 12 via the channel-shaped connecting member 20 by welding or the like, and the angle member 18 is engaged with the corner portion 4 of the column 3. As a result of the positioning in the lateral direction, lateral vibration is prevented, and the load that acts on the shaft body 2 such as the weight of the operator when the upper surface contact plate 19 contacts the upper end surface of the corner 4 of the column 3. Will be supported.

また、図１に示したように、軸体２の下方の適宜位置、本実施例ではその下端部に柱３の角部４に係合可能な下方の角部係合部８等からなる下部受け部材２１を溶接等により固着している。図１２はその下部受け部材２１を拡大して示した側面図、図１３は正面図、図１４は平面図である。図示のように、下部受け部材２１は、前記下方の角部係合部８を構成するアングル材２２と、そのアングル材２２の外面に溶接等により固着され、アングル材２２と軸体２とを連結するチャンネル状連結部材２３とから構成される。なお、この下部受け部材２１のチャンネル状連結部材２３は、前記上部受け部材１７のチャンネル状連結部材２０より長い寸法に形成され、図１に示したように使用状態において梯子１１が適度に傾斜するように構成されている。因みに、下部受け部材２１用のチャンネル状連結部材２０をロッド状の連結部材に変更して軸体２を貫通した状態に固定し、前記連結部材の外方側を軸体２の反対側へ突出させながら前記固定位置を変更し得るように構成すれば、必要に応じて下部受け部材２１と軸体２との間隔を縮小して梯子１１の傾斜角を変えたり垂直状態に変更したりすることも可能である。さらに、図示のようにアングル材１８，２２の内側の柱３の角部４と当接する部分に硬質ゴム等の適宜素材からなる変形可能な当接部材を設けることにより、係合時における柱３側の損傷を防止したり、柱３の角部４との当接部分の摩擦力を増大して係合による横振れ防止作用を向上することができる。 Further, as shown in FIG. 1, a lower portion including a lower corner engaging portion 8 and the like which are engageable with the corner 4 of the column 3 at the lower end of the shaft 2 in this embodiment, in this embodiment. The receiving member 21 is fixed by welding or the like. 12 is an enlarged side view of the lower receiving member 21, FIG. 13 is a front view, and FIG. 14 is a plan view. As shown in the figure, the lower receiving member 21 is fixed to the angle member 22 constituting the lower corner engaging portion 8 and the outer surface of the angle member 22 by welding or the like, and the angle member 22 and the shaft body 2 are connected to each other. It is comprised from the channel-shaped connection member 23 to connect. The channel-like connecting member 23 of the lower receiving member 21 is formed to have a length longer than that of the channel-like connecting member 20 of the upper receiving member 17, and the ladder 11 is inclined moderately in use as shown in FIG. It is configured as follows. Incidentally, the channel-shaped connecting member 20 for the lower receiving member 21 is changed to a rod-shaped connecting member and fixed in a state of passing through the shaft body 2, and the outer side of the connecting member protrudes to the opposite side of the shaft body 2. If the configuration is such that the fixing position can be changed while reducing the distance between the lower receiving member 21 and the shaft body 2 as necessary, the inclination angle of the ladder 11 can be changed or changed to a vertical state. Is also possible. Further, as shown in the figure, by providing a deformable abutting member made of a suitable material such as hard rubber in a portion that abuts on the corner 4 of the pillar 3 inside the angle members 18 and 22, the pillar 3 at the time of engagement is provided. Side damage can be prevented, or the frictional force of the contact portion with the corner 4 of the column 3 can be increased to improve the side shake prevention effect due to engagement.

前述のように、軸体２の両側には所定間隔を置いて足掛け部材９，１０が付設される。図１５はそれらの足掛け部材９，１０を示した拡大部品図である。本実施例では、図５に示したように足掛け部材９，１０の各付設位置に合わせて雌ねじ部材２４を軸体２を貫通した状態に溶接等により一体的に設け、それらの雌ねじ部材２４の両側から足掛け部材９，１０の雄ねじ部２５を螺入して締付け固定することにより梯子１１を形成するように構成している。なお、図１６は足掛け部材９，１０を付設した状態を示した正面図である。因みに、本実施例では、足掛け部材９，１０をねじ込み式に構成した場合を示したが、初めから軸体２に対して溶接等により固着する形態も可能であることはいうまでもない。 As described above, the footrest members 9 and 10 are attached to both sides of the shaft body 2 at a predetermined interval. FIG. 15 is an enlarged part view showing the footrest members 9 and 10. In this embodiment, as shown in FIG. 5, the female screw member 24 is integrally provided by welding or the like so as to penetrate the shaft body 2 in accordance with the attachment positions of the footrest members 9, 10. The ladder 11 is formed by screwing the male threaded portions 25 of the footrest members 9 and 10 from both sides and fastening them. FIG. 16 is a front view showing a state in which the footrest members 9 and 10 are attached. Incidentally, although the case where the footrest members 9 and 10 are configured to be screwed is shown in the present embodiment, it is needless to say that the shaft body 2 may be fixed to the shaft body 2 by welding or the like from the beginning.

次に、仮設用支柱を構成する軸体に足場部材を付設して仮設作業台として使用可能に構成した第２実施例に関して説明する。図１７はその第２実施例の使用状態を例示した使用状態説明図であり、また図１８は足場部材を折畳んだ状態を例示した状態説明図である。図中、２６は本実施例に係る仮設用支柱で、前記第１実施例の仮設用支柱１と基本的に異なるところはない。本実施例の場合には、仮設用支柱２６を柱３に平行に沿わせるため、上方の角部係合部２７と仮設用支柱２６との間隔と、下方の角部係合部２８と仮設用支柱２６との間隔とを同じ間隔に設定した点と、足場部材２９を仮設用支柱２６に対して付設するための取付手段を付加した点で異なるが、その他の構成は共通しているので、同様の構成部分には同じ符号を付して前記第１実施例における説明を援用する。しかして、本実施例の場合には、運搬時や設置作業時においては図１８に示したように足場部材２９を折畳んだ状態で取扱い、設置後の使用状態においては図１７に示したように足場部材２９を拡開して仮設作業台として使用することになる。なお、本実施例では、足場部材２９を仮設用支柱２６を構成する軸体３０に対して直接的に付設した場合を示したが、例えば仮設用支柱２６に固着された足掛け部材に取付けることにより軸体３０に対して間接的に付設することも可能である。 Next, a description will be given of a second embodiment in which a scaffold member is attached to a shaft body constituting a temporary support column so that it can be used as a temporary work table. FIG. 17 is an explanatory diagram illustrating the usage state of the second embodiment, and FIG. 18 is an explanatory diagram illustrating the state in which the scaffold member is folded. In the figure, reference numeral 26 denotes a temporary support column according to the present embodiment, which is basically not different from the temporary support column 1 of the first embodiment. In the case of the present embodiment, since the temporary support column 26 is parallel to the column 3, the interval between the upper corner engaging portion 27 and the temporary support column 26, and the lower corner engaging portion 28 and the temporary support column 26 are temporarily set. It differs in that it is set to the same distance from the support column 26 and in that an attachment means for attaching the scaffold member 29 to the temporary support column 26 is added, but other configurations are common. The same components are denoted by the same reference numerals, and the description in the first embodiment is incorporated. Thus, in the case of this embodiment, the scaffold member 29 is handled in a folded state as shown in FIG. 18 during transportation and installation work, and as shown in FIG. 17 in the use state after installation. The scaffold member 29 is expanded to be used as a temporary work table.
