リート製でも鋼板製でもよい。The technical problem of the present invention is solved by the following means. Claim 1 is a mold for molding a PC panel on a sheet laid on a surface plate, removing the mold frame, and molding the PC panel on the upper stage on the PC panel molded earlier. Set the frame and perform molding work
By repeating this, the upper PC panels are molded in sequence.
When stacking up, it is a PC panel molding to the earlier

のを確実に防止できる。 A PC is used by a crane every time the mold is removed as in the past.
It is not necessary to pull up the panel and remove it from the mold, or to move the removed PC panel in preparation for the next molding, which reduces the burden of arranging the crane. Since it is not necessary to dismiss the PC panel each time the mold is removed, a long curing period as in the past is not required. Also, the surface plate and PC panel are concrete
Even if the levelness is not accurate because it is made of sand,
Sufficient levelness can be secured by spraying mortar etc.
Therefore, even if you do not use a special expensive and high-precision surface plate,
PC panels with high surface area can be manufactured. Furthermore, on plywood
Use a formwork in which horizontal steel pipes are piled and fixed at the ends and bottom.
Therefore, plywood can be used for weight reduction and cost reduction.
Function, and it is connected on top of adjacent upper steel pipes.
The veneer is passed and fixed with a vise, so the upper end of each form opens

For No. 3, a vinyl sheet or the like is sufficient for merely separating, but a water-absorbent sheet is used to prevent the consonants generated from fresh concrete from adhering to the tile surface or the like. In the case of a water-absorbent sheet, a myriad of connecting holes are opened, so that the connoro is effectively absorbed.

This is a state in which the PC panel P3 of the step is molded. In this way, the sheet 13 is laid on the lower PC panel P2, and the foam tie (registered trademark) 4 is connected to the outer end of the lateral anchor 14 embedded in the lower PC panel P2 in advance.
The upper mold 3 is fixed by attaching the mold clamp 5 and pressing the lower steel pipe 7 of the mold 3 from the outside with the mold clamp 5.

By connecting 5 to each other, it is possible to prevent the left and right molds 3 and 3 from being pushed outward by the pressure of concrete and expanding.
Reinforcing bars are similarly connected between the horizontal anchors of the front and rear formwork.

When the connecting plate 17 is passed over the adjacent upper steel pipes 7 and fixed with the vise 18, the upper ends of the molds 3 can be reliably prevented from opening. In the figure, only one position on the left front side is shown, but it goes without saying that it is used for the entire four corners.

場合と同じである。FIG. 4 shows an example of molding at two locations on a single concrete surface plate 2 at the same time. (1) is a plan view,
(2) is a sectional view. Although only the lowermost PC panel P1 is shown in this figure, manufacturing the upper PC panels in sequence on the PC panel P1 is the same as the above case.

The surface plate 2 can be used as it is as a parking lot. If unnecessary, it may be destroyed by heavy equipment and removed.

養生期間も工期も短縮される。During the construction of a building, after the slabs on each floor are cast and cured, the slabs can also be used as the concrete surface plate 2. In this case, the PC panel molded on the slab can be immediately assembled on the floor as it is, so the work is significantly simplified compared to the conventional method of pulling it from the ground,
Curing period and construction period are shortened.

However, the platen made of steel plate requires equipment costs such as a stand, and cannot be easily installed in a narrow construction site.

Since the panel is molded and the mold is removed, the previously molded PC panel is used as a surface plate, and the mold for molding the upper PC panel is set on it and the molding process is repeated. In the space of one PC panel, many PC panels can be manufactured. Therefore, it does not require a wide stockyard or stock shelves as in the past.

大型車両を手配するなど、運搬に伴う費用や作業が軽減
される。As described above, since the concrete surface plate or the previously molded PC panel can be used as the surface plate, the PC panels can be mass-produced even at a construction site where there is not enough space. as a result,
Costs and work involved in transportation such as arranging large vehicles can be reduced.

に、工期の大幅短縮が可能となる。Since the molded PC panels are sequentially stacked, curing is performed during the stacking after molding. Also,
Since work that requires strength to the PC panel such as transportation and unloading work is unnecessary, shorten the curing period,
Can be assembled immediately and cured in the assembled state. As a result, the construction period can be greatly shortened.

型枠の上端が開くのを確実に防止できる。 Each time the mold is removed from the machine, a PC is used with a crane.
It is not necessary to pull up the panel and remove it from the mold, or to move the removed PC panel in preparation for the next molding, which reduces the burden of arranging the crane. Since it is not necessary to dismiss the PC panel each time the mold is removed, a long curing period as in the past is not required. In addition, the concrete surface plate and
Sprinkle sand or level mortar on top of the exposed PC panel
After ensuring the levelness, the sheet is laid on top of it
Since the method of placing concrete in the state is adopted,
Since the board and PC panel are made of concrete, the levelness is
Water, even if not accurate, by spraying sand or level mortar
The flatness can be sufficiently secured, and a special expensive and high-precision surface plate is used.
A PC panel with high flatness can be manufactured without using it.
In addition, stack horizontal steel pipes on the top and bottom of the plywood.
Since the fixed formwork is used, the weight and cost can be reduced.
Plywood can be used for the
Since the connecting plate is passed over the ips and fixed with a vise, each
It is possible to reliably prevent the top of the formwork from opening.

きるので、無駄がない。According to claim 2, concrete is cast on the ground surface and is used as a surface plate, and a large number of PC panels are molded and stacked on top of it. Molding equipment cost can be saved because there is no need to install a frame. After the construction is completed, it can be used as a parking lot, so there is no waste.

The walls on each floor can be precast and immediately assembled. As a result, it is not necessary to pull up the PC panel from the ground to the upper floor with a large crane, and the assembling work is greatly simplified.

れる。According to a fourth aspect of the present invention, a water absorbent sheet is used as a sheet to be laid on a surface plate or an already molded PC panel, tiles are laid on the sheet, and concrete is poured. Since the water-absorbing sheet absorbs the water-absorbing sheet, the tile does not adhere to the tile surface. As a result, it is not necessary to remove the cleaning pad from the tile surface after the mold is removed, and the post-processing load is reduced.
【0053】また、吸水性シートが下段のPCパネルと
上段のPCパネルとの間のクッションの作用をするの
で、上側のPCパネルの荷重が均等に分散され、下段の
PCパネルに無理な力がかかるのを防止できる。Further, since the water absorbent sheet acts as a cushion between the lower PC panel and the upper PC panel, the load of the upper PC panel is evenly distributed and an unreasonable force is applied to the lower PC panel. This can be prevented.

る。According to a fifth aspect of the present invention, a horizontal anchor is embedded in the previously molded PC panel, and the horizontal anchor is used to fix the upper stage formwork. Since the upper PC mold can be fixed by using the lower PC panel that has been previously molded, as long as the PC panels have the same shape, the PC panels can be manufactured by stacking multiple PC panels.
