Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.
FIGS. 1 to 5 relate to an embodiment of an external heat insulating panel for a formwork according to the present invention and an outer panel ventilation method using the same, and FIG. 1 shows an external heat insulating panel for a frame to be built in a flat portion. FIG. 2 is a perspective view and a plan view of a frame / outer heat insulation panel for building in the protruding corner, and FIG. 3 is a perspective view of a state of being built in the lower surface of the opening and the side of the opening, FIG. 4 is a perspective view and a side view of a frame / outer heat insulation panel for building on the lower surface of the opening, and FIG. 5 is a perspective view and a side view of the frame / outer heat insulation panel for building on the side of the opening.

  This external heat insulation panel for formwork is an external heat insulation panel for external heat insulation of concrete buildings. After placing the internal formwork and assembled concrete as an external formwork, it is left as it is. This is a state in which an exterior base material and a heat insulation board are attached to the wall, and a vertical ventilation groove is formed between the exterior base material and the external heat insulation board. The ventilation grooves in the direction are formed to communicate with each other.

  That is, for example, as shown in FIG. 1, the mold-form external heat insulation panel 10 includes a hard foam plastic heat insulation board 11 and an exterior base material 12 provided on the outdoor side of the hard foam plastic heat insulation board 11. A vertical ventilation groove 13 extending in the vertical direction is formed on the outdoor surface of the heat insulation board 11, and joint joint portions 14 are formed as steps in opposite directions at the left and right ends of the exterior base material 12. An elastic plastic joint member 15 is provided on one side of 14.

  A hard foam plastic heat insulation board 11 constituting the form-cum-use external heat insulation panel 10 is a foam plastic board formed of a thermoplastic resin or a thermosetting resin material having a high heat insulation effect. For example, polystyrene foam, polyurethane foam, Polyethylene foam, polypropylene foam, phenol foam and the like are used.

  In particular, as the heat insulation board 11 made of hard foam plastic, since it is attached to the outer surface of concrete as an external heat insulation construction method, it is preferable that the moisture content contained in the concrete can be permeated and is excellent in moisture permeability. Therefore, it is preferable to use a rigid polystyrene foam bead method that allows easy processing of the longitudinal ventilation grooves 13.

  This beaded rigid polystyrene foam does not allow water to pass through, but allows water vapor (humidity) to pass through. The moisture permeability coefficient is about 100 to 300 ng / m2sPa, and the moisture permeability coefficient of concrete is 15 to 30 ng / m2sPa. It is superior in moisture permeability compared to the existing one.

  The heat-insulating board 11 made of rigid foam plastic preferably has a density of 20 kg / m 3 or more from the viewpoint of thermal conductivity, more preferably has a density of 27 kg / m 3 or more, and a thickness of 30 to 60 mm or more is required. Preferably, the thickness needs to be 40 to 60 mm or more from the viewpoint of next-generation energy saving.

  A plurality of vertical ventilation grooves 13 extending in the vertical direction in a state of being built on the surface on the outdoor side are formed on the heat insulating board 11 of such hard foam plastic, and the exterior base material 12 is formed by the vertical ventilation grooves 13. The adhesive area changes, and the adhesive strength changes accordingly.

  For example, when a beaded foamed styrene board is used as the heat insulation board 11 and a fiber-mixed inorganic board is used as the exterior base material 12, the bond strength varies slightly depending on the density of the heat insulation board 11, but an average bond strength of 3.0 kg / cm 2. Can be secured. On the other hand, because the wind pressure, vertical stress or horizontal stress at the time of an earthquake, weight of the exterior material, and the like are applied to the outer heat insulating panel 10 combined with a formwork, a load strength of at least 1000 kg / m 2 is necessary in consideration of a safety factor. It becomes. Furthermore, the side pressure when placing concrete is about 6 ton / m2.

  Therefore, in the outer heat-insulating panel 10 combined with a beaded foam styrene board as the heat-insulating board 11 and the fiber-mixed inorganic board as the exterior base material 12, the bending elasticity as the bonded structure is important. In order to make the deflection 1.0 mm or less, the effective adhesion area other than the vertical ventilation groove 13 cannot be made about 33% or less.

  Therefore, in the outer heat insulation panel 10 also used as a formwork, if the width is 910 mm, for example, the non-bonding length in the width direction is 300 mm, and if one groove width of the vertical ventilation groove 13 is 40 mm, If the width of one groove is set to 30 mm, ten grooves can be formed. However, if the width of one groove is increased to about 100 mm, the strength against the side pressure of concrete decreases.

  As for the depth of the vertical ventilation groove 13, when the groove depth is increased, the heat insulation effect of the vertical ventilation groove 13 is reduced, and the strength against the lateral pressure of the concrete is also reduced. On the other hand, in order to allow ventilation from the lower part to the upper part of the building by the vertical ventilation groove 13, a groove depth of at least 15 mm or more and 18 mm is necessary, and preferably the groove depth is 20 mm or more.

  In such an external heat insulation panel 10 also used as a formwork, the thickness of the heat insulation board 11 is as long as the non-adhesion length in the width direction is 300 mm as the effective adhesion area of the heat insulation board 11 and the groove depth of the vertical ventilation groove 13 is 20 mm. When the thickness is 50 mm, the total cross-sectional area of the vertical ventilation grooves 13 is 13.2% of the total cross-sectional area of the heat insulating board 11. Similarly, when the thickness is 60 mm, 11.0% and when the thickness is 100 mm 0.7%.

  Therefore, in this outside heat-insulating panel 10 also used as a formwork, the total cross-sectional area of the vertical ventilation grooves 13 of the heat-insulating board 11 is 0.6 to 15% of the total cross-sectional area of the heat-insulating board 11 so All of the lateral pressure strength against the concrete, the air permeability by the vertical ventilation grooves 13 and the adhesive strength with the exterior base material 12 can be ensured. More preferably, the total cross-sectional area of the vertical ventilation grooves 13 of the heat insulation board 11 is determined by the heat insulation board 11. The total cross-sectional area may be 0.7 to 13.2%.

  Next, since the exterior base material 12 of the external heat insulation panel 10 also serving as a formwork is provided on the outdoor side of the heat insulation board 11 made of hard foam plastic, the exterior base material 12 attached to the outside with respect to the inner heat insulation board 11. It is preferable to use a material whose moisture permeability coefficient of the outer packaging material increases toward the outside.

  Many commercially available panels that can be used as the exterior base material have a moisture permeability smaller than that of the polystyrene foam of the bead method, and therefore, those having at least a moisture permeability coefficient of 100 ng / m 2 Spa (500 ng / m 2 Spa or less) are selected. Good, preferably 200 ng / m 2 Spa or more.

  On the other hand, from the relationship with the exterior material, for example, the exterior coating material has a moisture permeability coefficient of about 500 ng / m 2 Spa, and the exterior base material has a moisture permeability coefficient of 500 ng / m 2 Spa or less, preferably 400 ng / m 2 Spa. The following are preferred.

  Therefore, it is preferable that the exterior base material 12 used in combination with the external heat insulation panel 10 also serving as a mold has a moisture permeability coefficient of about 200 to 400 ng / m 2 Spa, for example, a lightweight mortar plate (moisture permeable) as the exterior base material 12. Coefficients (coefficient: 243 ng / m2sPa) and a coating material (moisture permeability coefficient: 500 ng / m2sPa) may be used as the exterior material.

  In addition, the exterior base material 12 is preferably set in a range where it can be built without using a crane in consideration of the construction work for external heat insulation construction. For example, when the width is 910 mm and the length is 3030 mm, the weight is 29.8 kg when the thickness is 12 mm and the specific gravity is 0.9, and the weight when the specific gravity is 1.1 is 36. 4 kg. Furthermore, when the thickness is 16 mm and the specific gravity is 0.9, the weight is 39.7 kg, and when the specific gravity is 1.1, the weight is 48.5 kg. On the other hand, the range that can be easily transported and constructed by two people without using a crane is preferably about 35 kg.

  Considering these points, the exterior base material 12 may be an inorganic board having a thickness of 10 to 16 mm and a specific gravity of 0.9 to 1.1, such as a lightweight mortar board or a fiber-mixed cement board.

  Further, the exterior base material 12 is provided with joint joints 14 at the left and right end portions thereof by steps in opposite directions. The joint portion 14 includes a step 14a (see the right side in FIG. 1) cut out at the center upper portion in the thickness direction and a step 14b (see the left side in FIG. 1) cut out at the center lower portion in the thickness direction. In the state of being configured and adhered to the heat insulating board 11, one step, in the illustrated example, the step 14b protrudes in the width direction.

  Therefore, in the joint joint portion 14 in which these two steps 14a and 14b are overlapped, the surface of the exterior base material 12 is flush and an L-shaped contact surface is formed. As a result, leakage of the poured concrete can be prevented from the joint portion.

  Further, in this exterior base material 12, a joint member 15 is attached to the upper surface of one step 14a, for example, a stick-shaped sealing material is attached with elastic plastic, and is crushed by the upper and lower steps 14a and 14b. The material 12 functions as a waterproof and stretchable sealing.

  By constructing the connecting joint portion 14 with the steps 14a and 14b, it is possible to easily build the outer frame 10 which is also used as a formwork by simply overlapping the steps 14a and 14b. Sealing effect against rain and rainwater can be obtained.

  Such an exterior base material 12 is disposed and bonded to the outdoor surface so as to close the vertical ventilation grooves 13 of the heat insulation board 11 made of hard foamed plastic, and the form-heat-insulating outer panel 10 is configured.

  Such an external heat insulation panel 10 also used as a formwork is connected to a portion that becomes a flat portion of the outer wall from the left and right via a connection joint portion 14 and is vertically abutted against each other in the vertical direction. It is built so that the grooves 13 communicate with each other, and an outer heat insulating ventilation method is applied.

  For example, the outer frame 10 also serves as a vertical end member along the connecting joint 14, for example. It is preferable to prevent the leakage of the cast-in concrete from the joints between the external heat insulation panels 10 which are also used as the molds, by arranging a sash or a square piercing member and pressing it with a lateral end member. Then, the vertical end material of the outer combined heat-insulating panel 10 for the formwork is formed by two single pipes and foam ties as horizontal end members arranged horizontally, as in the conventional construction of the formwork for placing concrete. While supporting the outer heat-insulating panel 10 for both the formwork and the placement space, the inner formwork is arranged, the interval is supported by a separator and a heat-insulating cone, and the vertical end material and the horizontal end material are provided outside the inner formwork. These two single pipes and a foam tie are arranged, and the inner and outer foam ties are connected and fixed via shaft feet.

  Further, a large number (necessary number) of anchor members are attached so as to penetrate the hard foamed plastic heat insulating board 11 from the outside of the exterior base material 12 of the mold-use external heat insulating panel 10 so as to protrude into the placement space.

  The anchor member may be of any shape as long as it can secure the mounting strength to the concrete, such as a simple screw-like one, in addition to those having an insert screw, especially those with a low thermal conductivity. It is preferable to ensure heat insulation performance.

  In this way, after the outer frame 10 combined with the formwork is arranged on the outdoor side, after the inner mold is built, the concrete is placed, the concrete is solidified and cured, and the outer combined heat insulating panel 10 up to the required height is formed. Repeated erection and concrete placement. In parallel with these, or after that, the exterior material is applied to the surface of the exterior base material 12 on the outdoor side.

  According to such an outer heat-insulating panel 10 for combined use with a formwork, the outer heat-insulating panel 10 for combined use with a formwork is arranged on the left and right so that the steps 14a and 14b of the connecting joints 14 at both left and right ends overlap each other. By placing the outer heat insulating panels 10 in the vertical direction while butting up each other, the vertical ventilation grooves 13 can be arranged on the left and right sides and communicated vertically.

  In addition, the joint joint 14 between the left and right steps 14a and 14b can easily align the outer heat-insulating panel 10 which is also used as a formwork, and the elastic plastic joint member 15 prevents leakage of the poured concrete. It is possible to carry out construction of exterior materials and the like without preparations such as removal of sludge.

  Thereby, the outer heat insulation ventilation method to the plane part of an outer wall can be easily constructed by using this form-molding external heat insulation panel 10.

  Next, another embodiment of the present invention will be described with reference to FIG. 2. The same reference numerals are given to the same portions as those of the already-explained mold / heat insulating panel 10, and the description thereof will be omitted.

  This formwork combined heat insulation panel 10A is for constructing a right-angled corner in combination with the formwork combined heat insulation panel 10 already described, and prevents the end face 11a of the heat insulation board 11 from being exposed, The anchor members 23, 23 of the orthogonal panels can be constructed without interference.

  In this outer frame heat-insulating panel 10A, a range equal to or greater than the panel thickness of the outer heat-insulating panel 10 is exposed from the end face 11a of the hard foam plastic heat-insulating board 11. A protruding corner base material 21 is provided on a surface perpendicular to the end face 11 a of the heat insulating board 11 and a portion corresponding to the thickness of the heat insulating board 11.

  For example, an outer corner base material 12 having the same specifications as the outer base material 12 is used, and the outer corner base material 12 is an inorganic plate having a thickness of 10 to 16 mm and a specific gravity of 0.9 to 1.1. Light mortar boards and fiber-mixed cement boards formed at right angles are used.

  If the anchoring member 23 is used to fix the protruding corner base material 21 to the concrete frame to be placed, it interferes with the other orthogonal panel 10 and cannot be installed.

  Therefore, in this outer heat-insulating panel 10A that is also used as a formwork, the connecting plate member 22 is disposed on the surface portion on the protruding corner side of the heat insulating board 11, and the end of the connecting plate member 22 is outside the protruding corner base material 21. The anchor member 23 can be attached to the protruding portion 22 a of the connecting plate member 22. The connecting plate member 22 is made of a metal plate, a synthetic resin plate, or the like, and is fixed in advance to the base material 21 for the corner from the inside with screws 24 and is bonded and fixed to the heat insulating board 11 with an elastic adhesive. The The connecting plate member 22 is made of, for example, a stainless steel plate having a thickness of 2.3 mm. The connecting plate member 22 may be a single continuous plate in the vertical direction of the outer heat-insulating panel 10A for both the formwork and the mounting pitch of the anchor member 23 and the screw 24. Depending on the above, it may be installed as a plurality of sheets divided in the vertical direction, preferably one sheet from the viewpoint of workability, and preferably divided from the viewpoint of heat insulation.

  The exterior base material 12 is provided on the side of the projecting portion 22 a of the connecting plate member 22 with an interval to drive the anchor member 23 in the same manner as the outer frame insulation panel 10 also serving as a formwork.

  The outer frame heat insulating panel 10A configured as described above is arranged at the protruding corner and is used in abutment with the outer heat insulating panel 10 which is also used for the mold frame at a right angle. Installed and used together with the inner formwork.

The board 11 is not exposed.

  The lower opening base material 32 has, for example, the same specifications as those of the exterior base material 12 and the corner base material 21, and the lower opening base material 32 has a thickness of 10 to 16 mm and a specific gravity of 0.9 to 1. 1. Inorganic plates such as lightweight mortar plates and fiber-mixed cement plates formed at right angles are used.

  If the base material 32 for the lower portion of the opening has the same cross-sectional shape as the base material 21 for the corners, and only the length is changed, a formwork / outer heat insulating panel for the corners is more easily prepared. 10A and the outer heat insulation panel 10B for both the upper and lower sides of the opening can be manufactured.

  In the outer heat insulation panel 10B that also serves as a formwork, the exterior base material 12 is attached to the surface portion of the heat insulation board 11 other than that covered with the base material 32 for the lower part of the opening.
