Description

本発明は、足場を組んでビルやマンション等の建物を築造する時にクレーンで吊り上げた建築資材等の荷物を受け取るために足場の外側部所要高さ位置に仮設される荷受けステージに関する。   The present invention relates to a load receiving stage temporarily installed at a required height position on the outer side of a scaffold in order to receive a load such as building materials lifted by a crane when building a building such as a building or a condominium with a scaffold.

従来の荷受けステージとして、特許公報等の公知文献を具体的に挙げることはできないが、従来、足場に荷受けステージを仮設する場合、足場の外側部所要高さ位置において、多数本の単管(鋼管からなる枠材単体)を縦横及び斜めにそれぞれ所要間隔に配し、これら単管の足場側連結部及び単管相互の交差部を一つずつパイプクランプにより固定して、梁部と斜材とからなる側面視略倒三角形のステージ本体を形成し、このステージ本体の梁部上に合板を敷設して、針金等で固定していた。   Known documents such as patent gazettes cannot be specifically cited as conventional load receiving stages, but conventionally, when temporarily placing a load receiving stage on a scaffold, a large number of single pipes (steel pipes) at the required height position on the outer side of the scaffold. The frame material is made up of vertical and horizontal and diagonally spaced at the required intervals, and the single pipe scaffolding side connection part and the crossing part of the single pipes are fixed one by one with pipe clamps, A stage body having a substantially inverted triangle shape as viewed from the side is formed, and a plywood is laid on the beam portion of the stage body and fixed with a wire or the like.

上記従来の方法では、足場外側部の地上から所要高さのところで、多数の単管とパイプクランプとによって、足場との連結作業、及び荷受けステージの枠組み作業を行うことから、パイプクランプの個数が増えて、取付作業に非常な手間と時間を要していた。また、荷受けステージは、建築の進行に伴い足場の高さが高くなると、足場の高所側に付け替える必要があるが、従来の方法では、荷受けステージの付け替えを行うたびにパイプクランプの取り外し・取り付け作業を行う必要があって、荷受けステージの仮設作業能率が非常に悪かった。   In the above-mentioned conventional method, the number of pipe clamps is reduced because a number of single pipes and pipe clamps are used to connect the scaffold and frame work of the load receiving stage at the required height from the ground outside the scaffold. Increasingly, the installation work required a lot of time and labor. Also, when the height of the scaffolding increases with the progress of construction, it is necessary to replace the receiving stage with the higher side of the scaffolding. In the conventional method, the pipe clamp is removed and attached each time the receiving stage is replaced. There was a need to work, and the temporary work efficiency of the receiving stage was very bad.

本発明は、上記の事情に鑑み、取付作業及び付け替え作業を簡単容易に行えて仮設作業能率を向上できる荷受けステージを提供することを目的としている。   In view of the above circumstances, an object of the present invention is to provide a load receiving stage that can easily perform attachment work and replacement work and can improve the temporary work efficiency.

The lower wedge 9 is inserted over the engagement hole 11 of the flange 10 and the scaffolding plate 12 is bridged between the beam frames 1 and 1 of the adjacent stage frame bodies 3 and 3.

上記荷受けステージSの構造について更に詳しく説明すると、ステージ枠体3を形成する梁枠1は鋼管からなるもので、この鋼管製梁枠1の先端部には、図3から分かるように、手摺り支柱取付用の縦杆13が上向きに垂設されていて、この縦杆13の上端部13aは、手摺り支柱14の下端部が外嵌して取り付けられる手摺り支柱取付ピンを形成している。   The structure of the load receiving stage S will be described in more detail. The beam frame 1 forming the stage frame 3 is made of a steel pipe, and as shown in FIG. A vertical rod 13 for supporting the column is suspended upward, and an upper end portion 13a of the vertical rod 13 forms a handrail column mounting pin to which the lower end portion of the handrail column 14 is externally fitted. .

上部接続シュー4は、図4の(a) ,(b) に示すように、上片部4aと下片部4bと側片部4cとによって側面視コ字状に形成されたもので、上片部4aと側片部4cにそれぞれ係合孔6が設けられており、側片部4cが梁枠1の先端部に溶接で固着されている。上部側楔8は、図4の(a) から分かるように、上端部側の前後幅がフランジ10の係合孔11の前後幅により僅かに大きく形成されており、また下端部には、フランジ10の係合孔11及び下片部4bの係合孔6を通過することはできるが、上片部4aの係合孔6を通過できないようにするための抜け止め突起15が設けられている。   As shown in FIGS. 4 (a) and 4 (b), the upper connection shoe 4 is formed in a U-shape in a side view by an upper piece portion 4a, a lower piece portion 4b, and a side piece portion 4c. An engagement hole 6 is provided in each of the piece 4a and the side piece 4c, and the side piece 4c is fixed to the tip of the beam frame 1 by welding. As can be seen from FIG. 4A, the upper wedge 8 is formed so that the front-rear width on the upper end side is slightly larger than the front-rear width of the engagement hole 11 of the flange 10, and the lower end portion includes a flange. 10 is provided with a retaining projection 15 that can pass through the engaging hole 11 and the engaging hole 6 of the lower piece 4b but cannot pass through the engaging hole 6 of the upper piece 4a. .

下部接続シュー5は、図5の(a) ,(b) に示すように、上片部5aと下片部5bと側片部5cとによって側面視コ字状に形成されたシュー本体5oと、このシュー本体5oの側片部5cに溶接により固着された平面視コ字状のブラケット16とからなるもので、斜材2の下端部がブラケット16に嵌合されて、ボルト・ナット17により上下方向回動自在に枢着されている。下部側楔9も、上部側楔8と同様に形成されていて、下端部には、フランジ10の係合孔11及び下片部4bの係合孔7を通過することはできるが、上片部5aの係合孔7を通過できないようにするための抜け止め突起15が設けられている。   As shown in FIGS. 5 (a) and 5 (b), the lower connection shoe 5 includes a shoe body 5o formed into a U-shape in a side view by an upper piece portion 5a, a lower piece portion 5b, and a side piece portion 5c. The bracket body 16 has a U-shaped bracket 16 fixed to the side piece 5c of the shoe main body 5o by welding. It is pivotally mounted so that it can rotate in the vertical direction. The lower wedge 9 is also formed in the same manner as the upper wedge 8 and can pass through the engagement hole 11 of the flange 10 and the engagement hole 7 of the lower piece 4b at the lower end portion. A retaining protrusion 15 is provided for preventing the portion 5a from passing through the engagement hole 7.

梁枠1の先端部に上向きに垂設された手摺り支柱取付用縦杆13の下端部には、下向きコ字状のブラケット18が溶接で固着されていて、このブラケット18に斜材2の上端部が嵌合され、ボルト・ナット19により上下方向回動自在に枢着されている。   A downward U-shaped bracket 18 is fixed by welding to the lower end portion of the vertical rail 13 for attaching the handrail struts suspended upward at the distal end portion of the beam frame 1, and the diagonal member 2 is attached to the bracket 18 by welding. The upper end portion is fitted and pivoted by a bolt / nut 19 so as to be rotatable in the vertical direction.

図6の(a) に示すように、手摺り支柱14を手摺り支柱取付用縦杆13の手摺り支柱取付ピン13aに取り付けるにあたり、手摺り支柱14の下端部を手摺り支柱取付ピン13aに外嵌すると、バネ(図示省略)の付勢力によってピン13aの外周面から突出する係合突起(図示省略)20が、手摺り支柱14の下端部に設けてある係合孔21に係合し、手摺り支柱14の下端部をピン13aに取付け固定する。手摺り支柱14を取り外す時は、手摺り支柱14下端部の係合孔21に係合しているピン13a側の係合突起20をバネ付勢力に抗して内方へ押し込んだ状態で、手摺り支柱14を引き抜けばよい。   As shown in FIG. 6 (a), when attaching the handrail support column 14 to the handrail support pin mounting pin 13a of the handrail support column mounting rod 13, the lower end portion of the handrail support column 14 is used as the handrail support column mounting pin 13a. When fitted externally, an engagement protrusion (not shown) 20 that protrudes from the outer peripheral surface of the pin 13a by an urging force of a spring (not shown) engages with an engagement hole 21 provided at the lower end portion of the handrail support column 14. The lower end portion of the handrail post 14 is attached and fixed to the pin 13a. When removing the handrail post 14, the pin 13a side engaging protrusion 20 engaged with the engagement hole 21 at the lower end of the handrail post 14 is pushed inward against the spring biasing force. The handrail post 14 may be pulled out.

上記のような構成よりなるステージ枠体3を複数使用して単管足場Wに荷受けステージSを設置するには、各ステージ枠体3の上部接続シュー4を、単管足場Wの支柱aに設けられた一つのフランジ10に跨嵌して、上部接続シュー4の係合孔6とフランジ10の係合孔11とに亘って上部側楔8を挿入し、楔8の頭部をハンマーで叩くことにより、この楔8を、シュー上下片部4a,4bの係合孔6,6とフランジ10,の係合孔11とに対し楔掛合させて、梁枠1の基端部を支柱aに固定する。   In order to install the load receiving stage S on the single pipe scaffold W using a plurality of stage frame bodies 3 having the above-described configuration, the upper connection shoe 4 of each stage frame body 3 is attached to the column a of the single pipe scaffold W. The upper wedge 8 is inserted across the engagement hole 6 of the upper connection shoe 4 and the engagement hole 11 of the flange 10 so as to straddle the single flange 10 provided, and the head of the wedge 8 is hammered. By hitting, the wedge 8 is wedge-engaged with the engagement holes 6 and 6 of the shoe upper and lower pieces 4a and 4b and the engagement hole 11 of the flange 10, and the base end portion of the beam frame 1 is supported by the column a. Secure to.

この場合、図4の(a) ,(b) に示すように、上部接続シュー4の上片部4aの所要部に切り起こし加工によって下向き突片22が設けられていることから、上部接続シュー4をフランジ10に跨嵌する時に、この下向き突片22がフランジ10の上面に係止してシュー4の上片部4aがフランジ10上面から浮き上がった状態となる。これにより、シュー上下片部4a,4bの係合孔6,6及びフランジ10の係合孔11に対する楔8の掛合作用が有効に働く。即ち、楔8は、シュー上片部4aの係合孔6の支柱側端部位置(イ)と、フランジ10の係合孔11の外周側端部位置(ロ)と、シュー下片部4bの係合孔6の支柱側端部位置(ハ)とに対して楔掛合するわけであるが、上記下向き突片22を設けない場合は、シュー上片部4aの係合孔6の支柱側端部位置(イ)と、フランジ10の係合孔11の外周側端部位置(ロ)との上下方向間隔が殆ど無くなるために、上記3つの位置(イ),(ロ),(ハ)による楔8の掛合作用が十分に機能しない。これに対し、下向き突片22を設けて両位置(イ),(ロ)の上下方向間隔を広げるようにすることにより、上記3つの位置(イ),(ロ),(ハ)が互いに上下方向に離れた状態の三角形を形成する(図4の(a) 参照)ため、楔8の掛合作用が有効に働いて、上部接続シュー4を支柱aのフランジ10に強固に固定することができる。   In this case, as shown in FIGS. 4A and 4B, since the downward projecting piece 22 is provided by cutting and raising the required portion of the upper piece 4a of the upper connecting shoe 4, the upper connecting shoe When 4 is straddled over the flange 10, the downward projecting piece 22 is locked to the upper surface of the flange 10, and the upper piece 4 a of the shoe 4 is lifted from the upper surface of the flange 10. Thereby, the engagement action of the wedge 8 with respect to the engagement holes 6 and 6 of the shoe upper and lower pieces 4a and 4b and the engagement hole 11 of the flange 10 works effectively. That is, the wedge 8 includes a column-side end position (A) of the engagement hole 6 of the shoe upper piece 4a, an outer peripheral side position (B) of the engagement hole 11 of the flange 10, and the shoe lower piece 4b. However, when the downward projecting piece 22 is not provided, the side of the engagement hole 6 of the shoe upper piece 4a on the support column side. Since there is almost no vertical distance between the end position (A) and the end position (B) on the outer peripheral side of the engagement hole 11 of the flange 10, the above three positions (A), (B), (C) The hooking action of the wedge 8 due to this does not function sufficiently. On the other hand, by providing a downward projecting piece 22 so as to widen the vertical distance between both positions (A) and (B), the above three positions (A), (B), and (C) can be Since the triangles separated in the direction are formed (see FIG. 4 (a)), the hooking action of the wedge 8 works effectively and the upper connection shoe 4 can be firmly fixed to the flange 10 of the column a. .

次に、同じステージ枠体3を形成する斜材2の下端部に取り付けてある下部接続シュー5を、上部接続シュー4と同じ様に、支柱aの所要高さ位置にある他のフランジ10に跨嵌して、下部側楔9を、下部接続シュー5の係合孔7とフランジ10の係合孔11とに亙って挿入し、この下部側楔9の頭部をハンマーで叩くことにより、この楔9を、シュー上下片部5a,5bの係合孔7,7とフランジ10の係合孔11とに対し楔掛合して、梁枠1の基端部を支柱aに固定する。   Next, the lower connection shoe 5 attached to the lower end portion of the diagonal member 2 forming the same stage frame 3 is attached to the other flange 10 at the required height position of the column a in the same manner as the upper connection shoe 4. The lower wedge 9 is inserted over the engagement hole 7 of the lower connection shoe 5 and the engagement hole 11 of the flange 10, and the head of the lower wedge 9 is hit with a hammer. The wedge 9 is wedge-engaged with the engagement holes 7 and 7 of the shoe upper and lower pieces 5a and 5b and the engagement hole 11 of the flange 10 to fix the base end portion of the beam frame 1 to the column a.

この場合も、下部接続シュー5の上片部5aの所要部には上部接続シュー4の場合と同様に、切り起こし加工によって下向き突片22が設けてあるから、下部接続シュー5をフランジ10に跨嵌する時に、シュー5の上片部5aがフランジ10上面から浮き上がった状態となり、これによりシュー上下片部5a,5bの係合孔7,7及びフランジ10の係合孔11に対する楔9の掛合作用を有効に働かせることができる。   Also in this case, as in the case of the upper connection shoe 4, the lower connecting shoe 5 is attached to the flange 10 because the downward projecting piece 22 is provided by cutting and raising the required portion of the upper piece 5 a of the lower connection shoe 5.
