Description

本発明は、支柱に設けられたくさび受けに対して、連結パイプが固設された連結部材をくさび部材によって固定する仮設足場用連結構造体に関する。 TECHNICAL FIELD The present invention relates to a connecting structure for temporary scaffolding, in which a connecting member to which a connecting pipe is fixed is fixed by a wedge member to a wedge receiver provided on a post.

一般に、建築物等の工事等に際しては、建築物の外周に仮設足場が設置される。この仮設足場は、複数本の支柱が所定間隔で配置され、各支柱間には足場板が架設されて複数階層の足場が形成される。このような仮設足場の架設作業にあっては、上方への足場の継ぎ足し作業の安全対策として、足場板を架設させる前に連結パイプが手すりとして先行して設置される。 2. Description of the Related Art Generally, temporary scaffolding is installed around a building when constructing a building or the like. In this temporary scaffolding, a plurality of columns are arranged at predetermined intervals, and scaffolding boards are installed between the columns to form a scaffolding of multiple levels. In such a temporary scaffold erection work, as a safety measure for the scaffold replenishment work, connecting pipes are installed as handrails prior to erecting scaffold boards.

手すりである連結パイプの設置に際しては、例えば、図１９に示すように、支柱１から突設されて支柱方向の筒部７が形成されたくさび受け５に対し、基部１１５に連結パイプＰが固設されてくさび受け５の筒部７と連通する連通部１２５，１３５が形成された側面視略コ字状の連結部材１１１が配置されて、連結部材１１１の連通部１２５，１３５とくさび受け５の筒部７に対して貫通楔着されるくさび部材１４０により固定される連結構造体１００が用いられる（例えば、特許文献１参照）。 When installing a connecting pipe as a handrail, for example, as shown in FIG. A connecting member 111 having a substantially U shape in a side view and having communicating portions 125 and 135 communicating with the cylindrical portion 7 of the wedge receiver 5 is disposed so that the communicating portions 125 and 135 of the connecting member 111 and the wedge receiver 5 are connected. A connection structure 100 fixed by a wedge member 140 penetrating and wedged with respect to the tubular portion 7 is used (see, for example, Patent Document 1).

この連結構造体１００において、連結部材１１１は、基部１１５の上端から延出してくさび受け５の上端に載置される上取付片１２０と、基部１１５の下端から延出してくさび受け５の下方に配置される下取付片１３０と、上取付片１２０と下取付片１３０とを一体に接続する接続片１１２と、上取付片１２０の下端から下方に突出されてくさび受け５の筒部７内に挿入される突片１１３と、基部１１５から上取付片１２０方向へ突出する突出部１５０とを有する。また、くさび部材１４０は、基部１１５側に上下方向に延びて接続部材１１１の突出部１５０が摺動自在に内嵌される凹状の長溝部１４５と、長溝部１４５の下端側を閉塞して形成された下側ストッパ部１４６と、長溝部１４５の下端に形成された貫通孔１４７と、くさび部材１４０の上端側に形成された上側ストッパ部１４８とを有する。 In this connection structure 100 , the connection member 111 includes an upper mounting piece 120 that extends from the upper end of the base portion 115 and is mounted on the upper end of the wedge receiver 5 , and an upper mounting piece 120 that extends from the lower end of the base portion 115 and extends below the wedge receiver 5 . A lower mounting piece 130 arranged, a connecting piece 112 integrally connecting the upper mounting piece 120 and the lower mounting piece 130, and a lower end of the upper mounting piece 120 projected downward into the cylindrical portion 7 of the wedge receiver 5. It has a protruding piece 113 to be inserted and a protruding portion 150 protruding from the base portion 115 toward the upper mounting piece 120 . The wedge member 140 is formed by closing the lower end side of the long groove portion 145 and the long groove portion 145 extending in the vertical direction toward the base portion 115 and into which the projecting portion 150 of the connecting member 111 is slidably fitted. , a through hole 147 formed at the lower end of the long groove portion 145 , and an upper stopper portion 148 formed at the upper end side of the wedge member 140 .

上記連結構造体１００では、くさび部材１４０を連結部材１１１の上取付片１２０の連通部１２５からくさび受け５の筒部７を経て下取付片１３０の連通部１３５へ挿通させることにより、くさび部材１４０が連結部材１１１とくさび受け５との間に楔着されて固定される。また、くさび部材１４０の挿通に際しては、くさび部材１４０の長溝部１４５に基部１１５から突出する突出部１５０が内嵌されていることにより、くさび部材１４０が突出部１５０に対して長溝部１４５を摺動させながら落下するため、くさび部材１４０は突出部１５０に進行方向を案内されて斜行することがない。 In the connection structure 100, the wedge member 140 is inserted from the communicating portion 125 of the upper mounting piece 120 of the connecting member 111 through the cylindrical portion 7 of the wedge receiver 5 and into the communicating portion 135 of the lower mounting piece 130. is wedged and fixed between the connecting member 111 and the wedge receiver 5 . Further, when the wedge member 140 is inserted, the protruding portion 150 protruding from the base portion 115 is fitted in the long groove portion 145 of the wedge member 140 , so that the wedge member 140 slides in the long groove portion 145 with respect to the protruding portion 150 . Since the wedge member 140 falls while being moved, the wedge member 140 is guided in the advancing direction by the projecting portion 150 and does not move obliquely.

しかしながら、上記連結構造体では、くさび受け５をくさび部材１４０と連結部材１１１の接続片１１２との挟持のみで固定するため、連結時の安定性が高いとは言いがたい。そこで、仮設足場設置の効率化やより高い安全性の確保等の観点から、連結パイプの連結時の安定性の更なる向上が求められる。 However, in the connection structure described above, the wedge receiver 5 is fixed only by sandwiching the wedge member 140 and the connection piece 112 of the connection member 111, so it cannot be said that the connection is highly stable. Therefore, from the viewpoint of improving the efficiency of temporary scaffolding installation and ensuring higher safety, there is a demand for further improvement in the stability of connecting pipes.

長溝部４５は、図３，６に示すように、くさび部材４０のくさび挿入方向に後端側から先端側にわたって直線状に延設される。この長溝部４５は、少なくともくさび本体４１の支柱側の面に設けられる。図示の実施形態の長溝部４５は、くさび本体４１の支柱側（前面側）からくさび受け側（後面側）にわたって貫通した貫通溝４５ａである。この長溝部４５では、図３，７に示すように、くさび部材４０の楔着時に連結部材１１の上側部材２０及び下側部材３０の前当部２２，３２の湾曲部２３，３３の後面が当接される。その際、図８に示すように、連結部材１１の連通部２５（３５）内方へ湾曲した湾曲部２３（３３）の頂点２３ａ（３３ａ）近傍が長溝部４５の内部に受容され、両側の湾曲部２３（３３）のすそ２３ｂ，２３ｂ（３３ｂ，３３ｂ）側において長溝部４５の溝縁部４６が当接される。そのため、くさび部材４０が挿入時及び楔着時に位置決めされて、がたつきの発生が抑制される。なお、長溝部４５では、溝幅は適宜であるが、例えば、湾曲部２３，３３の後面との当接位置が湾曲部２３，３３と支柱１の円周面２との当接位置より外側となる程度の幅とすることが当接時の安定性の観点から好ましい。 As shown in FIGS. 3 and 6, the long groove portion 45 extends linearly from the rear end side to the front end side in the wedge insertion direction of the wedge member 40 . The long groove portion 45 is provided at least on the support side surface of the wedge body 41 . The long groove portion 45 in the illustrated embodiment is a through groove 45a penetrating from the support side (front side) of the wedge body 41 to the wedge receiving side (rear side). 3 and 7, when the wedge member 40 is wedged, the rear surfaces of the curved portions 23 and 33 of the front contact portions 22 and 32 of the upper member 20 and the lower member 30 of the connecting member 11 are abutted. At that time, as shown in FIG. 8, the vicinity of the apex 23a (33a) of the inwardly curved curved portion 23 (33) of the communicating portion 25 (35) of the connecting member 11 is received inside the long groove portion 45, The groove edge portion 46 of the long groove portion 45 abuts on the side of the skirts 23b, 23b (33b, 33b) of the curved portion 23 (33). Therefore, the wedge member 40 is positioned during insertion and wedging, and rattling is suppressed. In the long groove portion 45, although the groove width is appropriate, for example, the contact position with the rear surface of the curved portions 23 and 33 is outside the contact position between the curved portions 23 and 33 and the circumferential surface 2 of the post 1. From the viewpoint of stability at the time of contact, it is preferable to set the width to the extent of

長溝部４５では、図６～８に示すように、溝縁部４６に傾斜面４７が形成され、くさび部材４０の楔着時に連結部材１１の上側部材２０または下側部材３０の少なくとも一方の前当部２２，３２の湾曲部２３，３３の後面が傾斜面４７と当接嵌入されることが好ましい。より好ましくは、傾斜面４７に連結部材１１の上側部材２０及び下側部材３０の両方の前当部２２，３２の湾曲部２３，３３の後面が当接嵌入される。このように、長溝部４５に傾斜面４７を形成することにより、連結部材１１の湾曲部２３，３３がより確実に長溝部４５内部に受容されて、くさび部材４０の挿入時及び楔着時の安定性が向上する。 In the long groove portion 45, as shown in FIGS. 6 to 8, an inclined surface 47 is formed in the groove edge portion 46, and when the wedge member 40 is wedged, at least one of the upper member 20 and the lower member 30 of the connecting member 11 is in front of the upper member 20 and the lower member 30. It is preferable that the rear surfaces of the curved portions 23 and 33 of the contact portions 22 and 32 are fitted in contact with the inclined surface 47 . More preferably, the rear surfaces of the curved portions 23 , 33 of the front contact portions 22 , 32 of both the upper member 20 and the lower member 30 of the connecting member 11 are fitted into the inclined surface 47 . By forming the inclined surface 47 in the long groove portion 45 in this manner, the curved portions 23 and 33 of the connecting member 11 are more reliably received in the long groove portion 45, and the wedge member 40 is inserted and wedged. Improves stability.

次に、本発明の仮設足場用連結構造体１０の連結手順について説明する。まず、図１に示す連結解除時は、連結構造体１０の連結部材１１がくさび受け５に対して固定されず、離隔可能な状態となっている。連結解除時において、くさび部材４０は、連結部材１１の連通部２５，３５から抜き取られている。 Next, the procedure for connecting the temporary scaffolding connecting structure 10 of the present invention will be described. First, when the coupling is released as shown in FIG. 1, the coupling member 11 of the coupling structure 10 is not fixed to the wedge receiver 5 and can be separated. When the connection is released, the wedge member 40 is pulled out from the communication portions 25 and 35 of the connection member 11 .

連結構造体１０をくさび受け５に対して連結する際には、図２，３に示すように、連結部材１１がくさび受け５にはめ込まれ、連結部材１１の上側部材２０がくさび受け５上に載置されるとともに、下側部材３０がくさび受け５の下方に配置される。その際、図４，８に示すように、連結部材１１の上側部材２０及び下側部材３０の前当部２２，３２に形成された湾曲部２３，３３の前面が、支柱１の円周面２に対して受容するように当接される。そのため、支柱１と当接する連結部材１１の安定性が向上する。また、図３，７に示すように、連結部材１１の上側部材２０では、上前当部２２の垂下部２４がくさび受け５の筒部７内に進入することにより、はめ込み時に連結部材１１のおよその連結位置が規定されるため、連結部材１１の位置決めが容易となる。 When connecting the connecting structure 10 to the wedge receiver 5, as shown in FIGS. While being placed, the lower member 30 is arranged below the wedge receiver 5 . At that time, as shown in FIGS. 2 is receptively abutted. Therefore, the stability of the connecting member 11 in contact with the column 1 is improved. As shown in FIGS. 3 and 7, in the upper member 20 of the connecting member 11, the hanging portion 24 of the upper front contact portion 22 enters the cylindrical portion 7 of the wedge receiver 5, so that the connecting member 11 does not move during fitting. Since the approximate connection position is defined, positioning of the connection member 11 is facilitated.

このように位置決めされた連結部材１１では、上側部材２０の上連通部２５と、くさび受け５の筒部７と、下側部材３０の下連通部３５とが上下に貫通するように連通される。そして、図２，３，４，７に示すように、連通された連結部材１１の上連通部２５とくさび受け５の筒部７と連結部材１１の下連通部３５に対して、くさび部材４０が貫通楔着される。 In the connecting member 11 positioned in this manner, the upper communicating portion 25 of the upper member 20, the cylindrical portion 7 of the wedge receiver 5, and the lower communicating portion 35 of the lower member 30 are vertically penetrated to communicate with each other. . Then, as shown in FIGS. 2, 3, 4 and 7, the wedge member 40 is attached to the upper communicating portion 25 of the connecting member 11, the cylindrical portion 7 of the wedge receiver 5 and the lower communicating portion 35 of the connecting member 11 which are in communication with each other. is wedged through.

ここで、くさび部材４０は、挿入時において、図８に示すように、連結部材１１の上側部材２０の上湾曲部２３や下側部材３０の下湾曲部３３の後面が長溝部４５内に当接されて摺動される。そのため、くさび部材４０が位置決めされて、安定して挿入させることができる。特に、長溝部４５に傾斜面４７が形成されることにより、連結部材１１の湾曲部２３，３３の後面が傾斜面４７に当接嵌入されるため、くさび部材４０の安定性がさらに高まる。このように、くさび部材４０が安定して挿入可能であることにより、作業性が向上して効率化を図ることができる。 Here, when the wedge member 40 is inserted, as shown in FIG. It is touched and slid. Therefore, the wedge member 40 is positioned and can be stably inserted. In particular, the formation of the inclined surface 47 in the long groove portion 45 allows the rear surfaces of the curved portions 23 and 33 of the connecting member 11 to contact and fit into the inclined surface 47, thereby further enhancing the stability of the wedge member 40. FIG. Since the wedge member 40 can be stably inserted in this manner, workability can be improved and efficiency can be improved.

連結部材１１の上連通部２５とくさび受け５の筒部７と連結部材１１の下連通部３５とに挿入されたくさび部材４０は、図３，４，７に示すように、くさび受け５の筒傾斜壁部６ｂと連結部材１１の前当部２２，３２との間に差し込まれる。この時、くさび本体４１の支柱側の面である直線部４２は、長溝部４５に連結部材１１の湾曲部２３，３３が当接嵌入されていることにより、連結部材１１の前当部２２，３２に近接または当接される。また、くさび本体４１のくさび受け側の面であるくさび傾斜部４３は、くさび受け５の筒傾斜壁部６ｂの傾斜に対応して当接される。 The wedge member 40 inserted into the upper communicating portion 25 of the connecting member 11, the tubular portion 7 of the wedge receiver 5, and the lower communicating portion 35 of the connecting member 11 is inserted into the wedge receiver 5 as shown in FIGS. It is inserted between the cylindrical inclined wall portion 6b and the front contact portions 22, 32 of the connecting member 11. As shown in FIG. At this time, since the curved portions 23 and 33 of the connecting member 11 are abutted and fitted into the long groove portion 45, the straight portion 42 of the wedge body 41 on the support side is 32 is close to or abuts. Further, the wedge inclined portion 43, which is the wedge receiving side surface of the wedge main body 41, abuts against the inclination of the cylindrical inclined wall portion 6b of the wedge receiver 5. As shown in FIG.

この状態からハンマー等によりくさび部材４０の後端側（上側）から差し込み方向へ打ち付けることにより、くさび本体４１のくさび傾斜部４３がくさび受け５の筒傾斜壁部６ｂに圧接されて楔着される。この時、くさび部材４０は支柱方向へ押圧されて、長溝部４５（傾斜面４７）が連結部材１１の湾曲部２３，３３に圧接される。そして、図８に示すように、連結部材１１の湾曲部２３（３３）は、前面側において当接された支柱１の円周面２と、後面側において支柱１の円周面２との当接部分より外側の湾曲部２３（３３）のすそ２３ｂ，２３ｂ（３３ｂ，３３ｂ）側で当接されたくさび部材４０の長溝部４５の両溝縁部４６，４６（傾斜面４７，４７）とで挟持された状態となる。そのため、連結時における連結部材１１のがたつき等が発生しにくくなり、適切な位置での安定的な連結が可能となる。 From this state, by striking the wedge member 40 from the rear end side (upper side) of the wedge member 40 in the insertion direction with a hammer or the like, the wedge slanted portion 43 of the wedge body 41 is pressed against the cylindrical slanted wall portion 6b of the wedge receiver 5 and wedged. . At this time, the wedge member 40 is pressed in the direction of the strut, and the long groove portion 45 (inclined surface 47 ) is pressed against the curved portions 23 and 33 of the connecting member 11 . As shown in FIG. 8, the curved portion 23 (33) of the connecting member 11 contacts the circumferential surface 2 of the strut 1 on the front side and the circumferential surface 2 of the strut 1 on the rear side. Both groove edge portions 46, 46 (slanted surfaces 47, 47) of the long groove portion 45 of the wedge member 40 which are in contact with the skirts 23b, 23b (33b, 33b) of the curved portion 23 (33) outside the contact portion, and It will be in a state of being sandwiched between. Therefore, rattling or the like of the connecting member 11 at the time of connection is less likely to occur, and stable connection at an appropriate position becomes possible.

このように連結された連結構造体１０の連結を解除する場合には、くさび部材４０の先端側（下側）からハンマー等により差し込み方向の反対側へ打ち付けることにより、くさび本体４１の圧接が解除されて容易にくさび部材４０を抜き取ることができる。 In order to release the connection of the connection structure 10 connected in this way, the pressure contact of the wedge body 41 is released by hitting the tip side (lower side) of the wedge member 40 with a hammer or the like in the opposite direction of the inserting direction. The wedge member 40 can be easily pulled out.

図９～１１は、第２実施形態に係る仮設足場用連結構造体１０Ａである。この連結構造体１０Ａでは、くさび部材４０の長溝部４５が連結部材１１の上側部材２０に設けられた抜け止めバンド部５０に遊嵌係着されている。なお、以下の説明において、第１実施形態と同一符号は同一の構成を表すものとして、その説明を省略する。 9 to 11 show a connecting structure 10A for temporary scaffolding according to the second embodiment. In this connection structure 10A, the long groove portion 45 of the wedge member 40 is loosely fitted to the retainer band portion 50 provided on the upper member 20 of the connection member 11 . In the following description, the same reference numerals as in the first embodiment represent the same configuration, and the description thereof will be omitted.

抜け止めバンド部５０は、図１１，１２に示すように、連結パイプ固定部１５の上端部と上側部材２０の上前当部２２の上端部との間に架設される板状部材である。この抜け止めバンド部５０は、図９～１１に示すように、くさび部材４０の貫通溝４５ａである長溝部４５に遊嵌係着されて、連結部材１１からのくさび部材４０の脱落を防止するとともに、くさび部材４０のくさび挿入方向を規制する。 As shown in FIGS. 11 and 12 , the retainer band 50 is a plate-like member that spans between the upper end of the connecting pipe fixing portion 15 and the upper end of the upper front contact portion 22 of the upper member 20 . As shown in FIGS. 9 to 11, the retaining band portion 50 is loosely engaged with the long groove portion 45, which is the through groove 45a of the wedge member 40, to prevent the wedge member 40 from falling off from the connecting member 11. Together, it regulates the wedge insertion direction of the wedge member 40 .

実施形態の抜け止めバンド部５０は、図１１，１２に示すように、連結パイプ固定部１５の上端部に一体に形成された帯状部材である。この抜け止めバンド部５０は、くさび部材４０の長溝部４５が遊嵌されるとともに、上側部材２０の上前当部２２方向へ折り曲げられて、溶接等の適宜の手法により先端部が上前当部２２の上端に固定されて架設される。図３，５において、符号５１は連結パイプ固定部１５の上端部から上方へ延設された縦帯状部、５２は抜け止めバンド部５０の折曲部、５３は連結部材１１の上連通部２５をまたぐように配置されてくさび部材４０の長溝部４５に遊嵌される横帯状部、５５は抜け止めバンド部５０の横帯状部５３を溶接した溶接部である。 As shown in FIGS. 11 and 12, the retainer band 50 of the embodiment is a belt-like member integrally formed with the upper end of the connecting pipe fixing portion 15. As shown in FIGS. The retaining band portion 50 is loosely fitted in the long groove portion 45 of the wedge member 40, bent toward the upper front contact portion 22 of the upper member 20, and welded or otherwise welded to the upper front contact portion. It is fixed and constructed on the upper end of the part 22 . 3 and 5, reference numeral 51 denotes a vertical belt-shaped portion extending upward from the upper end portion of the connection pipe fixing portion 15; 52, a bent portion of the retainer band portion 50; 55 is a welded portion obtained by welding the horizontal belt-like portion 53 of the retainer band portion 50 .

連結構造体１０Ａでは、くさび部材４０の長溝部４５に連結部材１１の上側部材２０に架設された抜け止めバンド部５０が遊嵌されているため、連結部材１１から脱落することがなく、紛失等のおそれがない。そこで、例えば、図９に示す連結解除時において、くさび部材４０を連結パイプＰ上に載置することができる。この連結構造体１０Ａにあっては、くさび部材４０の長溝部４５に遊嵌された抜け止めバンド部５０が、縦帯状部５１により横帯状部５３が連結パイプ固定部１５の上端部から上方へ離隔された位置で架設されている。そのため、連結部材１１の上部側からくさび部材４０を連結パイプＰの筒方向へ引き下げることが可能となり、連結パイプＰ上にくさび部材４０を脱落させることなく適切に載置させることができる。これにより、くさび部材４０が連結パイプＰから不必要に突出することがなく、作業の妨げになるおそれがない。 In the connection structure 10A, the retaining band portion 50 installed on the upper member 20 of the connection member 11 is loosely fitted in the long groove portion 45 of the wedge member 40, so that the connection structure 10A does not fall off from the connection member 11 and is lost. There is no risk of Therefore, for example, the wedge member 40 can be placed on the connecting pipe P when the connection is released as shown in FIG. In this connection structure 10A, the retainer band portion 50 loosely fitted in the long groove portion 45 of the wedge member 40 is moved upward from the upper end portion of the connection pipe fixing portion 15 by the vertical belt portion 51 and the horizontal belt portion 53 . They are erected at separated positions. Therefore, the wedge member 40 can be pulled down in the cylindrical direction of the connecting pipe P from the upper side of the connecting member 11, and the wedge member 40 can be appropriately placed on the connecting pipe P without falling off. As a result, the wedge member 40 does not unnecessarily protrude from the connecting pipe P, and there is no fear of interfering with the work.

また、連結構造体１０Ａの連結時では、図１０，１１に示すように、くさび部材４０の長溝部４５に抜け止めバンド部５０が遊嵌されていることにより、くさび部材４０は上下方向に略直動される。そのため、楔着に際して、くさび部材４０のくさび挿入方向が規制されて、安定してくさび部材４０を挿入させることができる。この挿入時において、くさび部材４０は、図８に示す第１実施形態と同様に、連結部材１１の上側部材２０の上湾曲部２３や下側部材３０の下湾曲部３３の後面が長溝部４５内に当接されて摺動される。そのため、くさび部材４０は、抜け止めバンド部５０によるくさび挿入方向の規制とともに、長溝部４５と連結部材の湾曲部２３，３３とによる位置決めによって、より安定した挿入が可能となる。特に、長溝部４５に傾斜面４７が形成されることにより、さらにくさび部材４０の安定性が高められる。従って、くさび部材４０の挿入時の優れた安定性が得られ、作業性がより向上して効率化を図ることができる。 Further, when the connecting structure 10A is connected, as shown in FIGS. 10 and 11, the retaining band portion 50 is loosely fitted in the long groove portion 45 of the wedge member 40, so that the wedge member 40 is substantially vertically movable. Directly moved. Therefore, when wedging, the wedge insertion direction of the wedge member 40 is regulated, and the wedge member 40 can be stably inserted. At the time of this insertion, the wedge member 40 has long groove portions 45 on the rear surfaces of the upper curved portion 23 of the upper member 20 of the connecting member 11 and the lower curved portion 33 of the lower member 30 in the same manner as in the first embodiment shown in FIG. It is abutted and slid inside. Therefore, the wedge member 40 can be inserted more stably by the regulation of the wedge insertion direction by the retaining band portion 50 and by the positioning by the long groove portion 45 and the curved portions 23 and 33 of the connecting member. In particular, the formation of the inclined surface 47 in the long groove portion 45 further enhances the stability of the wedge member 40 . Therefore, excellent stability is obtained when inserting the wedge member 40, and workability is further improved, and efficiency can be improved.

図１４，１５は、第３実施形態に係る仮設足場用連結構造体１０Ｂである。この連結構造体１０Ｂでは、くさび部材４０の長溝部４５が、くさび本体４１の支柱側の面に設けられてくさび受け側へ貫通しない凹状溝４５ｂからなる。凹状溝４５ｂは、図１６に示すように、第１実施形態と同様にくさび部材４０の楔着時に連結部材１１の湾曲部２３（３３）の後面が当接され、湾曲部２３（３３）の頂点２３ａ（３３ａ）近傍が凹状溝４５ｂの内部に受容される。そのため、くさび部材４０が挿入時及び楔着時に位置決めされて、がたつきの発生が抑制される。なお、凹状溝４５ｂの溝深さは特に限定されないが、連結部材１１の湾曲部２３（３３）との当接時に湾曲部２３（３３）を十分に受容可能であればよい。 14 and 15 show a temporary scaffolding connection structure 10B according to the third embodiment. In this connecting structure 10B, the long groove portion 45 of the wedge member 40 is formed of a recessed groove 45b provided on the support side surface of the wedge body 41 and not penetrating to the wedge receiving side. As shown in FIG. 16, the concave groove 45b abuts the rear surface of the curved portion 23 (33) of the connecting member 11 when the wedge member 40 is wedged as in the first embodiment. The vicinity of the vertex 23a (33a) is received inside the concave groove 45b. Therefore, the wedge member 40 is positioned at the time of insertion and wedging, and rattling is suppressed. The groove depth of the concave groove 45b is not particularly limited as long as it can sufficiently receive the curved portion 23 (33) of the connecting member 11 at the time of contact with the curved portion 23 (33).

また、連結構造体１０Ｂでは、図１４に示すように、くさび部材４０のくさび本体４１の後端側に抜け止めピン６０を設けてもよい。抜け止めピン６０は、くさび本体４１の連結部材１１の上側片部２１，２１側の面に、上側片部２１，２１間の距離より長くなるように突設される。そのため、例えば連結構造体１０Ｂの連結解除時等において、くさび部材４０を連結部材１１に挿入した場合、抜け止めピン６０は上側部材２０の上側片部２１，２１に係止されて、くさび部材４０の脱落が防止される。 In addition, in the connecting structure 10B, as shown in FIG. 14, a retaining pin 60 may be provided on the rear end side of the wedge body 41 of the wedge member 40. As shown in FIG. The retainer pin 60 is projected from the surface of the connecting member 11 of the wedge body 41 on the side of the upper pieces 21 , 21 so as to be longer than the distance between the upper pieces 21 , 21 . Therefore, when the wedge member 40 is inserted into the connecting member 11 when the connecting structure 10B is disconnected, for example, the retaining pin 60 is locked by the upper pieces 21, 21 of the upper member 20, and the wedge member 40 is prevented from falling off.

図１７は、第４実施形態に係る仮設足場用連結構造体１０Ｃである。この連結構造体１０Ｃでは、図１８に示すように、くさび部材４０のくさび本体４１の後面に凹状のパイプ受け部４８が形成されているとともに、くさび部材４０のくさび本体４１の先端面に前面側から後面側にかけて先端凹面部４９が形成されている。 FIG. 17 shows a temporary scaffolding connection structure 10C according to the fourth embodiment. In this connection structure 10C, as shown in FIG. 18, a concave pipe receiving portion 48 is formed on the rear surface of the wedge main body 41 of the wedge member 40, and the front end surface of the wedge main body 41 of the wedge member 40 is formed. A tip concave surface portion 49 is formed from the rear surface side to the rear surface side.

パイプ受け部４８は、くさび部材４０のくさび本体４１後面に後端からくさび挿入方向へ直線状に延設された連結パイプＰの外周面に対応して受容可能な凹状の部位からなる。パイプ受け部４８の形状は連結パイプＰの外周面が受容可能であれば特に限定されない。図１７に示す実施形態では、パイプ受け部４８が、貫通溝４５ａと、貫通溝４５ａに連接されるパイプ受け凹面部４８ａとで構成される。このパイプ受け部４８を有するくさび部材４０は、図１７に示す連結解除時において、パイプ受け部４８が連結パイプＰの外周面を受容するように連結パイプＰ上に載置される。そのため、連結解除時にくさび部材４０を連結パイプＰ上に安定して載置させることができ、連結解除状態を維持しやすくなる。 The pipe receiving portion 48 is formed of a concave portion that can receive the outer peripheral surface of the connecting pipe P, which is linearly extended from the rear end of the wedge body 41 of the wedge member 40 in the wedge insertion direction. The shape of the pipe receiving portion 48 is not particularly limited as long as the outer peripheral surface of the connecting pipe P can be received. In the embodiment shown in FIG. 17, the pipe receiving portion 48 is composed of a through groove 45a and a pipe receiving concave portion 48a connected to the through groove 45a. The wedge member 40 having the pipe receiving portion 48 is placed on the connecting pipe P so that the pipe receiving portion 48 receives the outer peripheral surface of the connecting pipe P when the connection is released as shown in FIG. Therefore, the wedge member 40 can be stably placed on the connecting pipe P when the connection is released, and the connection release state can be easily maintained.

先端凹面部４９は、上側部材２０の上湾曲部２３及び下側部材３０の下湾曲部３３のそれぞれの内部側湾曲面に対応した湾曲面形状からなる。くさび部材４０では、挿入時に連結部材１１の上側部材２０の上湾曲部２３や下側部材３０の下湾曲部３３とくさび本体４１の先端部が接触することがある。そこで、くさび本体４１の先端面に先端凹面部４９を設けることにより、くさび本体４１の先端部の上湾曲部２３やの下湾曲部３３との引っかかりや衝突等が発生しにくくなって、くさび部材４０を円滑に挿入させることができる。 The tip concave surface portion 49 has a curved surface shape corresponding to the inner curved surface of each of the upper curved portion 23 of the upper member 20 and the lower curved portion 33 of the lower member 30 . When the wedge member 40 is inserted, the upper curved portion 23 of the upper member 20 and the lower curved portion 33 of the lower member 30 of the connecting member 11 may come into contact with the distal end portion of the wedge body 41 . Therefore, by providing the distal end concave portion 49 on the distal end surface of the wedge body 41, the distal end portion of the wedge body 41 is less likely to be caught or collided with the upper curved portion 23 or the lower curved portion 33. 40 can be smoothly inserted.

なお、本発明の仮設足場用連結構造体は、前述の実施例のみに限定されるものではなく、発明の趣旨を逸脱しない範囲において構成の一部を適宜に変更して実施することができる。例えば、第１実施形態の連結構造体におけるくさび部材に、第３実施形態の連結構造体におけるくさび部材に設けられた抜け止めピンを設けていることにより、くさび部材の脱落を防止することができる。 The connection structure for temporary scaffolding of the present invention is not limited to the above-described embodiments, and can be implemented by appropriately changing a part of the structure without departing from the gist of the invention. For example, by providing the wedge member of the connecting structure of the first embodiment with the retainer pin provided on the wedge member of the connecting structure of the third embodiment, the wedge member can be prevented from coming off. .

以上のとおり、本発明の仮設足場用連結構造体は、支柱に設けられたくさび受けに対して安定的に連結することができる。そのため、従来の仮設足場用連結構造体の代替として有望である。 As described above, the connection structure for temporary scaffolding of the present invention can be stably connected to the wedge receiver provided on the post. Therefore, it is promising as an alternative to conventional connecting structures for temporary scaffolding.
