従来から、消波ブロックを成形する消波ブロック成形用型枠が提案されている。 Conventionally, a mold for forming a wave-dissipating block for forming a wave-dissipating block has been proposed.

この消波ブロック成形用型枠１は、図１に図示したように上方突状部１Ａと、この上方突状部１Ａの下方に分岐する３つの下方突状部１Ｂとから成る中空体であり、複数の分割型枠２で構成されており、具体的には、この分割型枠２夫々の端部に突設されるフランジ３同志を重合させ、この重合させたフランジ３夫々に形成される孔４（合致孔）に棒材８を嵌挿させることで分割型枠２同志を連結して消波ブロック成形用型枠１を組み立てることができる。尚、本実施例と同一構成部分には同一符号を付した。 As shown in FIG. 1, the wave-dissipating block forming mold 1 is a hollow body composed of an upper projecting portion 1A and three lower projecting portions 1B branching below the upper projecting portion 1A. The plurality of split molds 2 are formed. Specifically, the flanges 3 projecting from the ends of the split molds 2 are superposed, and the superposed flanges 3 are formed. By inserting the bar 8 into the hole 4 (matching hole), the divided molds 2 can be connected together to assemble the wave-dissipating block forming mold 1.

この固定部７は、最上段の足載せ部14ｂの左右両端部に板材を突設し、この板材を前述した補強フランジ３Ｃの小フランジ３Ｄに添設される添設部６とし、この添設部６の孔５と小フランジ３Ｄの孔４とが合致して形成される合致孔に固定用棒材９を嵌挿することで小フランジ３Ｄに対して固定し得るように構成されている。第一足場体14は、この固定用棒材９として、分割型枠２同志を連結する際に使用される棒材８をそのまま転用している。尚、符号10は固定用棒材９を固定する楔部材である。 The fixing portion 7 has a plate member projecting from both left and right end portions of the uppermost footrest portion 14b, and this plate member is used as an attachment portion 6 attached to the small flange 3D of the reinforcing flange 3C described above. The fixing member 9 is inserted into a matching hole formed by matching the hole 5 of the portion 6 with the hole 4 of the small flange 3D, and can be fixed to the small flange 3D. The first scaffold 14 uses the bar 8 used when connecting the divided molds 2 as the bar 9 for fixing as it is. Reference numeral 10 denotes a wedge member for fixing the fixing bar 9.

第二足場体15は、図４に図示したように下方突状部１Ｂの上面部（傾斜面）に載置される載置部15ａと、この載置部15ａの長さ方向に多段に並設される板状の足載せ部15ｂと、載置部15ａの一側に立設される手摺部15ｃとで構成されている。 As shown in FIG. 4, the second scaffold 15 includes a placement portion 15 a placed on the upper surface portion (inclined surface) of the downward projecting portion 1 B, and a plurality of stages in parallel in the length direction of the placement portion 15 a. It comprises a plate-like footrest portion 15b provided and a handrail portion 15c erected on one side of the placement portion 15a .

この第二足場体15は、消波ブロック成形用型枠１の下方突状部１Ｂの上面部に形成されて該下方突状部１Ｂの突出方向に長さを有する縦フランジ３Ａの上方位置から回避した側方所定位置に載置されるように構成されている。 The second scaffold 15 is formed from the upper position of the vertical flange 3A formed on the upper surface portion of the lower protruding portion 1B of the wave-dissipating block forming mold 1 and having a length in the protruding direction of the lower protruding portion 1B. It is configured to be placed at a predetermined side position that is avoided.

具体的には、この下方突状部１Ｂの縦フランジ３Ａの上方位置から回避した側方所定位置である下り湾曲面に載置部15ａを載置するとともに、後述する固定部７により横フランジ３Ｂの小フランジ３Ｄに固定した際、足載せ部15ｂが水平状態となるよう、載置部15ａの下面が下方突状部１Ｂの傾斜湾曲面の勾配に合致する形状に設定されている（図５参照）。 Specifically, the mounting portion 15a is mounted on a downward curved surface that is a predetermined side position avoided from the position above the vertical flange 3A of the lower protruding portion 1B, and the horizontal flange 3B is fixed by the fixing portion 7 described later. When fixed to the small flange 3D, the lower surface of the mounting portion 15a is set to a shape that matches the gradient of the inclined curved surface of the lower protruding portion 1B so that the footrest portion 15b becomes horizontal (FIG. 5). reference).

これは、下方突状部１Ｂの上面部に形成される縦フランジ３Ａの孔４への棒材８の嵌挿作業及び除去作業は、前述した第一足場体14に載って行われるが、下方突状部１Ｂは上方突状部１Ａに向けて上り傾斜し且つ距離があるため全ての部位を第一足場体14上で行うことができない。 This is because the work of inserting and removing the bar 8 from the hole 4 of the vertical flange 3A formed on the upper surface of the lower protrusion 1B is performed on the first scaffold 14 described above. Since the projecting portion 1B is inclined upward toward the upper projecting portion 1A and has a distance, it is not possible to perform all the parts on the first scaffold body 14.

よって、後に上方突状部１Ａに形成される縦フランジ３Ａの孔４への棒材８の嵌挿作業及び除去作業を行うための第二足場体15に載って残りの部位に対する作業を行うことになるが、この際、第二足場体15が縦フランジ３Ａの上方位置にあったのでは縦フランジ３Ａの孔４への棒材８の嵌挿作業及び除去作業が困難となってしまう。 Therefore, work on the remaining part on the second scaffold 15 for inserting and removing the bar 8 into the hole 4 of the vertical flange 3A to be formed later on the upper projecting portion 1A. However, at this time, if the second scaffold 15 is located above the vertical flange 3A, it is difficult to insert and remove the bar 8 from the hole 4 of the vertical flange 3A.

そこで、本実施例は、第二足場15を側方所定位置にずらすことにより前述した問題が生じることなく良好に作業が行えることになる。 Thus, in this embodiment, the second scaffold 15 can be favorably operated without causing the above-described problems by shifting the second scaffold 15 to a predetermined side position.

また、第二足場体15は、消波ブロック成形用型枠１のフランジ３へ固定するための固定部７が設けられている。 The second scaffold 15 is provided with a fixing portion 7 for fixing to the flange 3 of the wave-dissipating block forming mold 1.

In the second scaffold 15, as the fixing bar 9, the bar 8 used when connecting the divided molds 2 is used as it is.

第三足場体16は、図４に図示したように上方突状部１Ａの下方部位に立て掛けし得る基部16ａと、この基部16ａに上下多段に並設される板状の足載せ部16ｂとで構成されている。 As shown in FIG. 4, the third scaffold 16 includes a base portion 16a that can lean against a lower portion of the upper projecting portion 1A, and plate-like footrest portions 16b that are arranged in parallel on the base portion 16a.
