  Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.

  The construction method of the heat insulating composite panel on the wall surface of the present invention is applied when the heat insulating composite panel 1 is directly bonded with the adhesive 3 to the wall surface 2 of the concrete of a building such as a reinforced concrete structure. This solves the problem of unevenness on the concrete wall 2 and internal condensation on the concrete wall 2 at the same time.

The concrete wall 2 or the like to which the construction method (hereinafter simply referred to as construction method) is applied to the wall surface of the heat-insulating composite panel may be any concrete surface such as a wall, column, beam bottom, or beam side. The concrete wall surface 2 includes a mortar wall surface.
The heat insulating composite panel 1 is any composite panel in which a hard urethane foam or extruded polystyrene foam heat insulating material 1a and a hard face material 1b such as a plaster board, a calcium plate, a flexible board, and a cement board are integrated. It is desirable that the surface of the heat insulating material 1a is provided with a moisture-proof material such as calcium carbonate paper.

In this construction method, when the thermal insulation composite panel 1 is constructed by being crimped to a concrete wall 2 or the like via an adhesive 3, the surface of the thermal insulation composite panel 1 to be crimped as shown in FIG. Two crossing directions, for example, FIG. 2 (a) at a height that can absorb unevenness such as a wall surface of concrete on the entire surface of a certain heat insulating material 1a (when the moistureproof material is provided, the entire surface of the moistureproof material). ), (B), the adhesive 3 is raised in a direction 3a parallel to the side edge (long side) of the heat insulating composite panel 1 and a direction 3b (parallel to the short side) perpendicular to the side 3a. Then, as shown in FIG. 1 (b), the adhesive 3 is pressed and spread to apply the adhesive 3 as shown in FIG. 1 (b).
In the conventional crimping method, it is not practical to absorb large unevenness with an adhesive in terms of the physical properties and cost of the adhesive used, but in this construction method, a large amount of adhesive 3 is applied. Therefore, the gap 4 between the concrete wall 2 and the heat insulating composite panel 1 due to the non-land is filled with the adhesive 3 (non-land compatibility), and the height that can absorb the non-land as the adhesive 3 In addition to using a material that can be swelled, it is applied to the entire surface of the heat-insulating composite panel 1 in a bowl shape, and is crimped and expanded so that two perpendicular bowl-shaped adhesives 3 The space between the two is reduced as much as possible, and the gap space 4 is reduced and subdivided to prevent internal condensation.

As the adhesive 3 that can be bulky like this, an adhesive mainly composed of calcium sulfide water salt such as inorganic GL bond (registered trademark), CA bond (registered trademark) or for repair Examples thereof include pre-prepared mortar (corresponding to a cement-based primer adjusting thick coating material of JIS A6916), or an adhesive such as organic urethane, modified silicone, and acrylic emulsion.
When using an inorganic adhesive, a water retaining agent or the like is generally added to avoid adhesion failure due to the dryout phenomenon that occurs when moisture is rapidly taken away by the adherend. In the case of applying to 1, the heat-insulating material of the foamed resin or the moisture-proofing material has high moisture-proofing property, so that the dry-out phenomenon does not occur even if no water retaining agent is added.

  Such an adhesive 3 is applied to the entire surface of the heat insulating material 1a which is the surface to be pressure-bonded of the heat insulating composite panel 1 (when the moistureproof material is provided, the entire surface of the moistureproof material) such as the concrete wall 2 2 in a direction that intersects, for example, as shown in FIG. 2 (a), a direction 3a parallel to the side edge (long side) of the heat insulating composite panel 1 and parallel to the long side. The adhesive 3 is applied in a bowl shape so as to rise in the direction (parallel to the short side) 3b, 3b at both ends of the adhesive 3a, or as shown in FIG. 2 (b) In addition to the adhesives 3b and 3b orthogonal to both ends of the adhesive 3a parallel to the long side part, the adhesive 3b in the direction orthogonal to the middle part (parallel to the short side part) is raised so as to be raised Apply.

Since the adhesives 3a and 3b are applied in two directions orthogonal to each other, it is possible to apply wrinkles according to the number of combs at a time by using a comb iron.
In this construction method, as shown in FIG. 3, a dedicated comb iron 10 is used, and the iron plate portion 11 is provided on both sides of the iron plate portion 11 in which a plurality of comb eyes 11 a are formed. A side plate portion 12 that restricts the angle and prevents the adhesive from protruding is provided, and a grip portion 13 is provided outside the iron plate portion 11.
Then, one apex angle of the side plate portion 12 is set to an angle of 60 degrees with respect to the application surface, thereby making the bottom side of the side plate portion 12 follow the application surface as shown in FIG. The application work can be performed in a state where the iron plate part 11 is held at an angle of 60 degrees with respect to the application surface.

  For example, as shown in FIG. 5, as a dedicated comb iron 10 </ b> A, an iron plate portion is provided at an end opposite to the comb eye 11 a which is the upper end portion of the iron plate portion 11 on which the comb eye 11 a is formed. 11 may be configured by connecting a connecting plate portion 14 having an angle smaller than an angle for holding 11 (for example, 60 degrees), and by providing the connecting plate portion 14 with a gripping portion 13, It is possible to work by reducing the angle of the comb iron 10A.

  For example, as shown in FIG. 3C, the comb eye 11a formed on the dedicated comb irons 10 and 10A may be a base-base comb eye with a triangle placed on the top of the rectangle, or A comb having a semicircular shape placed on the upper part of the rectangle or a comb having only a rectangle may be used as long as the adhesive 3 can be applied in a raised shape.

The size and pitch of such combs 11a is such that the uneven surface area of the concrete wall 2 can be directly crimped without leveling mortar even if the unevenness difference is 5mm per 1.8m. What is necessary is just to ensure the adhesion area, for example, 0.4-0.44 m <2> / m <2> or more in the pressure bonding method in which the adhesive is applied in the above-described lattice shape or the dumpling tension method in which the adhesive is scattered in the shape of the dumpling.
Therefore, for example, the width B of the comb 11a is about 17 mm, the height H is 11 to 15 mm, the distance P (pitch) between adjacent combs 11a is about 28 mm, and the amount of the adhesive 3 applied is 4. According to a trial calculation when there is no unevenness when 2 kg / m 2, the adhesive area can be secured to about 0.75 m 2 / m 2 if the thickness after bonding of the adhesive 3 is 5 mm. Even if the thickness after pressure bonding of 3 is 9 mm, an adhesive area of about 0.41 m 2 / m 2 can be secured, and if the thickness of the adhesive 3 after pressure bonding is 3.75 mm, the bonding area is 100%. It can be.

  According to such special comb irons 10 and 10A, the conventional comb irons have only been used for the application of adhesives in the construction of tiles and the like and design patterning in plastering and paint finishing. However, it is not intended to improve the construction quality such as positive adjustment of the adhesive surface, securing the adhesive shape, and stabilizing the coating amount. For this purpose, a range where bonding can be performed with the unevenness adjusted is set, and based on this, the relationship between the minimum bonding thickness determined by the coating amount and the maximum bonding thickness determined by the minimum required bonding area is examined, and the comb eye 11a The shape is set and can be securely bonded.

  Also, the bonding area varies depending on the unevenness of the concrete wall 2 that is the bonding surface. However, the bonding area is larger than that of the conventional method, and the adhesive 3 is placed in two orthogonal directions 3a and 3b. By applying and spreading in a shape, the space 4 between the adhesives 3 can be reduced and subdivided to suppress the occurrence of internal condensation. For example, even if internal condensation occurs, the finely condensed condensation Water is sealed, and it is possible to prevent the occurrence of actual damage such as wetting of the walls and floors and mold.

  Further, according to the dedicated comb irons 10 and 10A, since the side plate portions 12 are provided on both sides of the iron plate portion 11, the trowel is applied when the adhesive 3 is applied to the heat insulating composite panel 1. The adhesive 3 does not leak out from the end portion of the plate portion 11, the small edge portion of the heat insulating composite panel 1, the surface of the heat insulating composite panel 1, etc. are not soiled, and the construction efficiency can be improved. In addition, by applying the adhesive 3 with the side plate portion 12 being traced along the surface of the heat insulating composite panel 1, the angle of the comb irons 10 and 10A can be kept constant. The coating width and coating height of the coating are stabilized, and the adhesive quality can be stabilized by setting the coating amount to an appropriate amount.

Next, the concrete construction method of the heat insulation composite panel 1 to the wall surface 2 of concrete is demonstrated.
First, the smoothness of the concrete wall 2 to be constructed is confirmed, and if it is within 5 mm per 1.8 m, the thermal insulation composite panel 1 is constructed directly without requiring any particular repair. If the smoothness is poor, smoothing mortar is applied to ensure smoothness within the above range.
Next, inking is performed and the finish surface position of the heat insulating composite panel 1 is determined. For example, when the heat insulating composite panel 1 is constructed on a vertical wall surface, the finishing surface position is determined by marking the horizontal floor surface and / or the vertical side wall surface perpendicular thereto.
Thereafter, the adhesive 3 is kneaded with water or the like according to the use of each adhesive. For example, the adhesive 3 and a specified amount of water (in the case of a mortar adhesive, an admixture is also added) are kneaded to adjust the viscosity to be suitable for application with a comb iron 10 or 10A.
Using the special comb iron 10 (10A), the adhesive 3 is applied to the entire surface of the heat insulating material 1a (the moistureproof material in the case where a moistureproof material is provided), which is the surface to be pressure-bonded of the heat insulating composite panel 1.
As described above, the adhesive 3 is applied in two intersecting directions, and the adhesive 3a in a direction parallel to the long side of the heat insulating composite panel 1 is applied to both ends of the comb iron 10. After applying with leaving a width of about a batch, the adhesive 3b is applied in a direction orthogonal to the both ends of the adhesive 3a and parallel to the short side of the heat insulating composite panel 1. In addition, you may make it apply | coat the adhesive agent 3b of the direction parallel to a short side also to the intermediate part of the adhesive agent 3a of the direction parallel to the long side of the heat insulation composite panel 1. FIG. In addition, each bowl-like adhesive 3a, 3b is applied at a predetermined interval from the end face of the heat-insulating composite panel 1 so that it does not protrude when it is spread out. For example, an interval of about 10 to 15 mm from the end face is secured, although it depends on the length.
The heat insulating composite panel 1 to which the adhesive 3 is applied is attached to the concrete wall 2 in accordance with the position where the ink is drawn out.
Then, the surface of the heat insulating composite panel 1 is crimped while adjusting the vertical and horizontal levels so as to strike the surface with a fixed tree. By rubbing, the adhesive 3 is expanded and there is almost no gap 4 between the adhesives 3, and the adhesive 3 is bonded to the concrete wall 2.

By repeating the application of the adhesive 3 with the comb iron 10 to the heat insulating composite panel 1, the application to the concrete wall 2, the level adjustment and the pressure bonding of the heat insulating composite panel 1, the heat insulating composite panels 1 are one by one. Glue.
After all the heat-insulating composite panels 1 have been bonded to the concrete wall 2 in this way, the adhesive 3 is sufficiently cured until it dries and hardens, putty treatment is performed on the joints, and interior materials such as cloth are applied. To do.

According to such a construction method, even if there is unevenness on the concrete wall 2 or the like, the mortar leveling construction process can be reduced, construction can be performed efficiently, and the construction period can be shortened.
In addition, by using the special comb iron, it is possible to easily secure the application amount and the application area of the adhesive and to stabilize the adhesive quality.
Furthermore, the filling degree and the sealing degree of the adhesive can be increased, and the effect of preventing and suppressing the internal condensation of the heat insulating composite panel can be enhanced.
In addition, if an inorganic adhesive is used as the adhesive, cleaning up after construction can be done simply by washing with water, and there are no problems (such as VOC) associated with the use of organic adhesives. can do.

In the above embodiment, the adhesive is applied in two orthogonal directions parallel to the long side and the short side of the heat-insulating composite panel. Two directions may be used.
In addition, it is not limited to the case where the application height of the adhesive is made equal, but at least the outer peripheral end side of the heat-insulating composite panel may be increased to increase the crimping force. The thus-adhesive is pushed and expanded with a higher pressing force, whereby the heat insulating composite panel can be more reliably bonded to the concrete wall surface.
Furthermore, in addition to the two-direction adhesives that intersect, at least the outer peripheral end of the heat insulating composite panel may be provided with an annular adhesive portion that is continuously applied in an annular shape. The gap between the wall and the like can be closed, and the slight remaining air can be prevented from moving to prevent internal dew condensation more reliably.
