Ｂａは縦ばた材、Ｃはセパレータである。(Prior Art) Conventionally, for example, in the case of a large amount of concrete curing when an oil storage tank is constructed using concrete, the temperature difference between the inside and outside of the concrete side wall of this tank is not increased, and the temperature drop rate of the entire side wall is large. In order to keep the concrete temperature as close as possible to the outside air temperature so that the temperature does not become large, it is necessary to control the heat generation on the side wall of the concrete to control the occurrence of temperature cracks. As a method for heat-retaining and curing the side wall surface for this purpose, as shown in FIG. 4, a curing sheet S is generally covered from the outside of the scaffold A of the wall form H. B is flat material,
Ba is a vertical material, and C is a separator.

け、取外しを行なう必要があった。(Problems to be Solved by the Invention) According to the conventional example, the thermal insulation air inside the curing sheet is dissipated due to the flapping of the curing sheet due to the wind, so the thermal insulation effect is small. Then, there is a problem that it is difficult to uniformly keep the temperature of the entire side wall by blowing in draft air from the joint portion of the curing sheet. Furthermore, it was necessary to attach and detach the curing sheet for each driving rod.
本発明の目的は、保温効果が向上し、均一な保温を可能

にある。(Means for Solving Problems) A feature of the present invention is that the mold body 2, the ribs 2a protruding from the back surface of the mold body, and the rib 2a arranged in contact with the back surface of the mold body are arranged. The curing sheet 3, the mold body, the heat-retaining air layer 6 surrounded by the ribs and partitioned by the ribs, and the presser sheet fixed to the mold body from the back side thereof. It is composed of members 4 and 5.

固定している。(Embodiment) An embodiment of the present invention will be described below with reference to FIGS.
The assembly formwork 1 is assembled in advance, for example, on site.
The assembly formwork 1 has a formwork body 2 made of metal foam, and ribs 2 are formed in the vertical and horizontal directions on the back surface of the formwork body.
a and 2a are projected. A curing sheet 3 is disposed on the back surface of the mold body 2 in a state of being in contact therewith. Further, the curing sheet 3 is fixed to the form main body 2 from the back surface thereof by lateral and vertical flap members 4 and 5 which are pressing members. Therefore, a space surrounded by the ribs 2a and the curing sheet 3 is formed in the heat retaining air layer 6 on the back surface of the mold body 2, and the heat retaining air layer is partitioned by the ribs. The flat material 4 holds the curing sheet 3, and the back surface of the flat material is fixed by the vertical material 5.

この横ばた材上に縦ばた材５を置くものである。The assembly of the mold 1 will be described. First, formwork body 2 on the ground
Then, the curing sheet 3 is placed on the formwork body, the flat material 4 is set on the protective sheet, and finally the vertical material 5 is placed on the horizontal material. .

後型枠１内にコンクリート９を打設する。The molds 1 assembled in this way are sequentially built up, and at the joint portion of each mold, the back surface of the mold body 2 is covered with the curing sheet 3, and the curing sheets are bound by a number line. After that, the molds 1 are fixed between the molds 1 by the separator 7 and the fasteners 8, and then the concrete 9 is poured into the molds 1.

うに、コンクリート保温効果は、本発明の方が従来例に
比較して、約５℃〜７．５℃高く、それだけ保温効果が
大きいことを示している。FIG. 3 is an experimental example in which the temperature change in the concrete of the present invention and the conventional example is measured over 5 days and the measured values are shown in the graph. The graph is that of the present invention, and the graph shows that of the conventional example. It is a thing. As is clear from these graphs, the concrete heat insulating effect of the present invention is higher by about 5 ° C. to 7.5 ° C. than that of the conventional example, which indicates that the heat insulating effect is large.

的に行える。Since the curing sheet 3 is attached at the same time as the mold 1 is assembled, it can be done in advance without affecting the side wall process, and the curing sheet can be attached and removed on site only by the join portion of the built-in form. It can be done automatically by attaching and detaching the formwork.
養生シート３の押え部材として、前記の実施例に示すよ
うにばた材４，５で兼用すれば、組立型枠１の構成部材
が少なくてすみ、構成が単純化できる。If the flap materials 4 and 5 are also used as the pressing member of the curing sheet 3 as shown in the above embodiment, the number of constituent members of the assembly formwork 1 can be reduced and the structure can be simplified.

安全に作業を進めることができる。(Effect of the invention) As described above, according to the present invention, since the curing sheet is arranged in contact with the back surface of the mold body, it is not affected by the wind, and the curing sheet is affected by the wind as in the conventional case. There is no risk of rattling and breakage or scattering of this sheet during the curing period. Further, the heat retaining effect is improved by the heat retaining air layer partitioned by the ribs, and uniform heat retaining is possible. Furthermore, the mounting and dismounting of the curing sheet can be significantly reduced, eliminating the crane work associated with mounting and dismounting.
You can work safely.
