- the formwork 10 of this embodiment is for placing concrete walls 14 in a basement room 12 (FIG. 2), and is arranged in parallel with each other.
- the first panel 16 and the second panel 18 are connected by a plurality of ribs 20 extending in the vertical direction.
- the air layer formed by the first panel 16, the second panel 18, and the ribs 20 is continuous in the horizontal direction to form the heat insulating layer 24.
- a plurality of support pieces 26 having a substantially T-shaped cross section extending in the longitudinal direction are formed at regular intervals on the main surface of the first panel 16 on the concrete wall 14 side.
- a water-permeable layer 28 such as a nonwoven fabric is adhered.
- the slit width a, the thickness b, the rib pitch P, and the wall thickness t are set to, for example, 12.5 mm, 32 thighs, 25 cycles, and 1 mm, respectively.
- the first panel 16, the second panel 18, the ribs 20, and the support pieces 26 are integrally formed by extrusion molding of a heat conductive hard synthetic resin such as polyvinyl chloride. Referring to FIG.
- a groove 40 is first formed on the upper surface of a slab 38 on which a spring tank 36 is formed.
- a water channel 42 will be set up within 0.
- the formwork 10 is assembled on the water passage 42 so that the bottom surface thereof comes into contact with the stopper 44 of the water passage 42.
- the first locking piece 32 of one mold 10 and the second locking piece 34 of the other mold 10 are butyl tape or the like. Bonded with waterproof double-sided tape 4.
- a concrete wall 14 is cast between the formwork 10 and the concrete retaining wall 46.
- the concrete paste When the concrete wall 14 is laid, the concrete paste is immersed in the permeable layer 28, so that after the concrete hardens, the concrete wall 14 and the concrete wall 14 can be used without using special joining members.
- the mold 10 is firmly joined. Before the concrete wall 14 is hardened, the excess water of the concrete flows into the headrace 30 through the permeable layer 28, flows down the headrace 30, and flows through the slab 3 8 The water is discharged to a spring tank 36 through a water pipe 48 provided in the basin. On the other hand, after the concrete wall 14 has hardened, the water that has leaked to the surface of the concrete wall 14 through the cracks 50 (FIG. 3) formed on the concrete walls 14 and 46 is converted to excess surplus. It is discharged to the spring tank 36 in the same manner as water.
- the permeable layer 28 When the surface of the concrete wall 14 is displaced due to crack 50 or the like, the permeable layer 28 is displaced accordingly. Therefore, transmission of the displacement to the main body of the mold 10 is prevented, and the mold 10 is prevented from being cracked or bent. Thus, the permeable layer 28 also functions as a buffer layer. In addition, heat from the concrete wall 14 is blocked by the heat insulating layer 24. Therefore, no condensation occurs on the surface of the mold 10 (the second panel 18).
- an inlet 52 for introducing concrete is formed in the permeable layer 28, and a reservoir 54 is formed so as to extend from the inlet 52 to the back. If the concrete thus formed is stored in the storage portion 54, the concrete wall 14 and the formwork 10 can be more firmly joined.
- a plurality of vertically extending hollow blocks 58 are formed at regular intervals instead of the support pieces 26 in the above-described embodiment.
- a permeable layer 28 such as a nonwoven fabric is adhered to the concrete wall 14 of the concrete wall 14.
- the space surrounded by the first panel 16, the block 58, and the permeable layer 28 becomes the headrace 30.
- the slit width a, thickness b, rib pitch P and wall thickness t are set to, for example, 12.5 thighs, 32 ml, 25 thighs, and 1 mm, respectively.
- the first panel 16, the second panel 18, the rib 20 and the block 58 are integrally formed by extrusion of synthetic resin such as polyvinyl chloride, for example. More stable molding is possible than in the embodiment.
- the heat insulation layer 24 is formed by an air layer, and the heat insulation layer 24 (and the support piece) is formed, for example, as in a form 60 shown in FIG. 26) may be formed of a foamed synthetic resin such as foamed rigid PVC. According to this formwork 60, the formwork The nailing of the finished interior material to the inner surface becomes stronger.
- a permeable layer 28 such as a non-woven fabric is formed to be relatively thick, and excess water or leakage from the concrete wall 14 is absorbed by the permeable layer 28. At the same time, this may flow down and be discharged from the bottom of the form 62. According to this formwork 62, since there is no need to form a headrace channel, the structure can be simplified and the manufacturing cost can be reduced.
- a third panel 66 is formed integrally with the support piece 26 (or the block 58) as shown in a mold 64 shown in FIG. 8, for example, and a plurality of water holes 6 are formed in the third panel 66. 8 may be perforated to form a permeable layer. According to the formwork 64, the nonwoven fabric does not need to be fixed in a subsequent step, so that the manufacturing process can be simplified.
- an anchor portion 70 buried in the concrete wall 14 is formed on the concrete wall 14 main surface of the third panel 66 to form the formwork 64 and the concrete wall 14. It may be possible to improve the bonding property of the steel. If a crack 50 (FIG. 3) occurs in the concrete wall 14, the position of the anchor portion 70 shifts, and if the formwork body 72 follows the shift, the formwork 64 may break. Therefore, in order to prevent the mold body 72 from following the displacement of the anchor portion 70, the anchor portion 70 is made of a force formed of a soft material such as an elastomer or a soft vinyl chloride. It is formed into a structure that can be easily cut as shown in FIG.
- the anchor portion 70 When the anchor portion 70 is formed of a soft material, the soft material of the anchor portion 70 and the hard material of the form body 72 are co-extruded (two-layer extrusion). Also, the first panel 16, the second panel 18, the third panel 66, etc. of the formwork 64 (FIGS. 8 and 9) should be formed of a transparent material such as polycarbonate acryl. You may. When these are made of a transparent material, the concrete can be installed while checking the installation state of the concrete from the indoor side, so that the workability can be dramatically improved and the jointability with the concrete wall 14 can be improved.
- finish interior materials such as stone * boards, tiles, etc. may be attached to nails, adhesives, or the like in advance or after construction on the indoor main surface of the heat insulating layer 24 in each of the above-described embodiments. May be used.
- Table 1 shows the flexural rigidity (E ⁇ I) and the maximum allowable bending moment for the current formwork, the formwork 10 (Fig. 1) and the formwork 56 (Fig. 5) of the embodiment. (F ⁇ Z).
- the block 58 is formed between the ribs 20. Such a hollow block 58 is formed at a position straddling the rib 20 as in, for example, a formwork 74 shown in FIG. Is also good.
- the first panel 16 and the first panel 16 as shown in the formwork 76, 78 and 80 shown in FIGS. 16 to 18, for example, respectively.
- a rib 82 that connects the two panels 18 at an angle may be formed.
- the mold 76 shown in FIG. 16 is formed by adding such a rib 82 to the mold 56 shown in FIG. 5, and the mold shown in FIG.
- Numeral 78 denotes such a rib 82 formed in a substantially V shape
- a mold 80 shown in FIG. 18 has a rib 82 formed in a substantially X shape. is there.
- Table 2 shows the details of formwork 74 (Fig. 15), formwork 76 (Fig. 16), formwork 78 (Fig. 17) and formwork 80 (Fig. 18).
- E ⁇ 1X (kg ⁇ cm 2 )
- weight Wkg / m
- the strength of the formwork is evaluated by the deflection 3 at the time of driving shown by the formula 1 and the maximum allowable bending moment M shown by the formula 2.
