Description
【発明の詳細な説明】 この発明は二重殻タンクの施工法に関するものである。[Detailed description of the invention] This invention relates to a construction method for a double shell tank.
二重殻タンクには、内外槽とも金属製又は外槽がコンク

重殻タンクの構築に際しては、工期を短縮するために次
のような工程で施工される場合が多い。Double shell tanks include those where both the inner and outer tanks are made of metal, or those where the outer tank is made of concrete and the inner tank is made of metal. When constructing these double-shell tanks, the following steps are often used to shorten the construction period.
１）完成されたコンクリートスラブに外槽底板およびな
らしのモルタルを打設する。1) Place the outer tank bottom plate and leveling mortar on the completed concrete slab.
２）内外槽の側板を連設すると共に内槽屋根を施工する
。2) Install the side plates of the inner and outer tanks and construct the inner tank roof.
３）底部保冷および内槽底板を施工する。3) Install bottom cold insulation and inner tank bottom plate.
４）内槽屋根を所定の位置に取付けると共に外槽底板を
施工する。4) Attach the inner tank roof to the specified position and construct the outer tank bottom plate.
５）検奔および側部、屋根部の保冷工事を行なう。5) Perform inspection work and cold insulation work on the sides and roof.

皇中の内外槽の側板の上をクレーンによシ吊シ込むか、
又は内外槽ｆｌｕ板の下部に搬入用の穴をあけ、そこを
通して運び込んでいた。Looking at this process, we can see that during the construction of the side panels of the inner and outer tanks,
It can be seen that much of the work is done inside the tank. Of course, this construction required many poor people, and these materials had to be hoisted onto a crane over the side panels of the inner and outer tanks of the conventional construction chamber.
Alternatively, a hole was made at the bottom of the flu board for the inner and outer tanks, and the material was transported through the hole.
しかし、クレーンによる吊シ込みは、工事中の側板の上
を通るので不安全であり、また側板によシ視界がさまた
げられるので危険であった。However, hoisting with a crane was unsafe because it passed over the side panels under construction, and it was also dangerous because the side panels obstructed the view.
一方側板に搬入用の大きな穴をあけることは、強度上重
要な側板の施工が不完全になる可能性がふえ、また側板
施工の安全面からも穴の太きさに制限がある等多くの問
題があった。On the other hand, drilling a large hole in the side plate for delivery increases the possibility that the construction of the side plate, which is important for strength, will be incomplete, and there are many restrictions such as restrictions on the thickness of the hole from the safety perspective of side plate construction. There was a problem.
この発明は上記のような実情にかんがみてなされたもの
であって、その目的は資材を安全に搬入して、工期を延
ばすことなく施工できるようにした二重殻タンクの施工
法を提供しようとするものである。This invention was made in view of the above-mentioned circumstances, and its purpose is to provide a method for constructing a double-shell tank that allows safe transport of materials and construction without prolonging the construction period. It is something to do.

してタンクを構築するものである。The construction method for this double-shell tank is characterized by providing an opening for carrying in materials in the bottom concrete slab, as well as providing a material transport path below the concrete slab that leads to the outside. The tank is constructed by transporting the fuel from the tank into the tank.

る。An embodiment of the method of this invention will be described below with reference to the drawings. In the figure, 1 is a raised concrete slab supported by columns 2, and this concrete slab 1 has an opening 3 for carrying in interest. Reference numeral 4 denotes a material transport path formed below the concrete slab 1 and leading to the outside.A rail 5 is laid on this punching path 4, and a trolley 6 is used to transport the material 7 from the outside to the position of the opening 3. It has become. Reference numeral 8 denotes a crane for carrying in materials 7 installed in the tank.
而して、内外側板９，１００建設と並行して、資材搬送
路から搬送された資材を開口部３からタンク内に搬入し
、内槽屋根、底部保冷及び内槽底板等の施工をする。In parallel with the construction of the inner and outer panels 9 and 100, the materials transported from the material transport path are carried into the tank through the opening 3, and the inner tank roof, bottom cold insulation, inner tank bottom plate, etc. are constructed.
なお、上記実施例は高床式コンクリートスラブの場合に
ついて述べたが、コンクリートスラブの下方にトンネル
状に資材搬送路を設けてもよい。In addition, although the above-mentioned example described the case of a raised concrete slab, a tunnel-shaped material conveyance path may be provided below the concrete slab.
この発明方法は上記のようなもので、内部工事用の資材
