Description

The present invention belongs to a heat insulating panel of a wooden building, and more specifically, a screw induction hole and a sealing part for the purpose of simplifying an outer insulation method for a wooden building and reducing a heat insulating defect and improving an air density in a wooden building. It relates to a thermal insulation panel.

If the construction method using a heat insulation panel is used, the outer insulation of the wooden building can be advantageously performed. This construction method is attracting attention for constructing a building with good cooling and heating efficiency because it is easy to air-tighten the building and insulates it so as to cover the structural frame of the building. In this external heat insulation method, a method of attaching a heat insulation panel from the outside of the frame of the wooden building is generally used, and the size of the heat insulation panel product and the module of the wooden frame are unified (for example, Patent Document 1 and Patent Document 2). .).

Ensuring airtightness is an important factor in constructing highly airtight and highly insulated wooden buildings. The outer-layer heat insulation method using a heat insulation panel is advantageous in that it requires less labor for airtight construction than a general filling heat insulation method, but the work for closing the gap between the heat insulation panels is unavoidable. There is actually a heat insulating panel that is devised so as not to give a gap to the butted portion (for example, Patent Document 3 and Patent Document 4).

JP 2001-355297 A (page 8, FIG. 1) Japanese Patent Laid-Open No. 08-232368 (4th page, FIG. 1 (b)) Japanese Patent Laid-Open No. 11-124927 (page 8, FIG. 1) Japanese Patent Laid-Open No. 2001-12007 (page 8, FIG. 1)

However, in a wooden building using a conventional heat insulation panel, the finish of the sealing material filled between the heat insulation panels is poor, and the finish of the wall surface tends to impair the beauty. In addition, it is difficult to adjust the necessary and sufficient amount of the sealing material that can secure the airtightness of the house, and the amount of sealing material used is more than necessary, which tends to increase the construction cost.

In addition, when actually installing the outer insulation, the simplest method is to cover the heat insulation panel from the outside of the wooden structure such as a pillar and fix it with nails, etc., but the case was covered with the conventional heat insulation panel. In the state, it is difficult to grasp the position of the column to which the nail or the like is fixed. Therefore, it is necessary to carefully fix the heat insulation panel, which hinders the shortening of the construction period.

There is a heat insulation panel in which the mark of the nail position is made according to the position of the pillar to be covered, but for example, when a hard material such as cement board is used as a member constituting the heat insulation panel, it is nailed or self-piercing type It is difficult to fix the heat insulation panel with screws, and the work of drilling the heat insulation panel before construction is inevitable. Moreover, when this thermal insulation panel is perforated at a construction site, the thermal insulation inside the thermal insulation panel may be damaged, and the performance of the thermal insulation panel may be deteriorated.

Also, the sealing material buried between the heat insulation panels fixed with a gap on the wall acts as a thermal bridge that thermally connects the indoor and outdoor of the wooden building to prevent heat insulation, and actually to the wooden building The installed insulation panel prevents the effect from being fully exerted. In order to prevent this, it is necessary to build a sealing groove after bringing the heat insulating materials inside the heat insulating panel into close contact with each other, but after fixing the heat insulating panel, a groove is constructed by a mechanical method. This is technically and labor-intensive, and requires a capital investment in the manufacturing plant for the method of constructing the grooves in the manufacturing process of the heat insulation panel.

As a part of a wall in a wooden building constructed using a frame construction method, a heat insulating panel made of a building surface material and a resin foam is manufactured, and this is used to insulate the wall of a wooden building. . The construction of the heat insulating panel used is that the length and width of the building surface material 10 in FIG. 2 is smaller than that of the resin foam 12, and the building surface material 10 is bonded to one side of the resin foam 12 to provide the heat insulating panel. Create By joining this heat insulation panel to the wall of the wooden building, a heat insulating layer formed by intimate contact between the resin foams is constructed on the wall from the outside of the wooden building frame.

A small hole is drilled at the mark position of a screw or nail in accordance with the standard when constructing a heat insulating panel on a wooden building in a stage before combining with a resin foam on a building surface material constituting the heat insulating panel. The size of the heat insulation panel that combines the building surface material and the resin foam is aligned with the module of the building.

The resin foam 12 in FIG. 2 is set to a resin that can be eroded by an organic solvent, and then the heat insulating panel 13 is manufactured, and the wall primer and the wall primer containing the organic solvent from above the heat insulating panel fixed to the casing. A space into which an irregular sealing material for filling the gaps between panels is formed by partially dissolving the protruding part on the resin foam with respect to the building surface material. Secure.

By constructing the heat insulation panel 13 according to the present invention as a part of the wall in the wooden building, the resin foams 12 at the panel butt portion can be in close contact with each other on the wall on which the heat insulation panel 13 is constructed. With this effect, the heat insulation layer formed from the resin foam 13 inside the heat insulation panel adjacent to each other has few continuous thermal bridges, and the heat insulation layer generated in the filling heat insulation method and the method using the conventional heat insulation panel Eliminate the thermal bridge. In addition, a concave portion having the difference between the length and width size of the building surface material and the resin foam as the width and the thickness of the building surface material as the depth is provided in the butt portion 14 of the heat insulating panel. This recess can be used as a space for sealing between heat insulating panels, and by filling the recess with an appropriate amount of an irregular sealing material, the airtightness and beautiful appearance of the wooden building can be ensured.

By using the building surface material 10 in which the small holes 11 are opened in advance according to the module of the wooden building as a component of the heat insulation panel which is the product of the present invention, This heat insulation panel can be accurately fixed to the building frame with screws. In addition, the work of drilling the building surface material 10 on the heat insulation panel on the site can be omitted, and the screw guided by the small hole 11 enters the heat insulation panel 13 and the wooden frame straightly during the construction. Reliability of screw strength after work is improved. In addition, there is no need to perform drilling work on the heat insulation panel at the site, so the workability is high, and the possibility that the resin foam inside the heat insulation panel will be damaged due to construction mistakes etc. and the heat insulation performance of wooden buildings will be reduced is also reduced. .

The heat insulation panel is standardized with the wooden building module in the whole size, and it is not structured to fit the heat insulation panel into the frame, so this heat insulation panel is against the frame of the wooden building. As shown in FIGS. 8 and 9, construction can be performed in either a vertical or horizontal orientation, so that the workability at the construction site is improved. In view of the above, the heat insulation construction method for a wooden building using the heat insulation panel according to the present invention enables the heat insulation construction of the wooden building's outer wall insulation work more efficiently than the conventional heat insulation panel and the construction method using the same. It can be expected that the construction precision will be a problem in ensuring airtightness and thermal insulation of the house. Moreover, since the direction of the heat insulation panel has vertical and horizontal degrees of freedom, it is possible to insulate the wall of the wooden building with the minimum number of sheets, and to suppress the generation of surplus materials.

The method of providing recesses for sealing on the heat insulation panel, which is not sufficient only by the thickness of the building surface material constituting the heat insulation panel, using the erosion action of the organic solvent on the resin foam is achieved by mechanical cutting. Compared with the method of forming this, it is simple and labor-saving, and the equipment investment for manufacturing the heat-insulated panel with recessed portions is not required. In addition, this method can provide a recess for injecting a sealing material having a sufficient depth to allow the amorphous sealing material to exert its effect, and the melted resin foam has adhesiveness to a sealing material resin such as modified silicone. Is advantageous over ordinary resin foams. In addition, airtightness of the wooden building to which the heat insulation panel is fixed is secured, and the external force applied to the wall body by the earthquake and strong wind is dispersed by the resin foam butt portion and soft material such as sealing to protect the wall body from cracks, etc. An effect is obtained.

The building surface material constituting the heat insulation panel body according to the present invention is perforated with small holes as shown in FIG. In order to make the small holes later function as marks of screws 17 etc. that fix the heat insulating panel to the wall structure by matching the heat insulating panel 14 in which the building face material 10 and the resin foam 12 are combined with the module of the wooden building, The interval is standardized in advance. Although the ceramic face material such as a fiber reinforced cement board is mainly used as the building face material 11, a wooden face material having sufficient rigidity such as a structural plywood may be used.

The resin foam 12 constituting the product of the present invention in combination with the building surface material 11 is one that can be eroded by a general organic solvent. Among them, a typical resin foam is a polystyrene foam heat insulating material. A board is mentioned. As shown in FIG. 2, the resin foam 12 and the perforated building surface material 10 are bonded together with their one ends in the length direction and the width direction aligned, so that a protruding portion 13 is formed on the surface of the resin foam. Occurs. A perspective view of the heat insulation panel is shown in FIG. 2, and a front view and a cross-sectional view are shown in FIGS. 3 to 5. The arrows on the drawings are common to FIGS. 3 to 5, and as shown in FIGS. 4 to 5, the resin foam 12 is not perforated in the manufacturing process.

As shown in FIG. 2, the small holes 11 processed in the building surface material 10 constituting the heat insulating panel 14 are standardized according to the housing module, and are standardized as shown in FIG. 8 or FIG. 9. This corresponds to a position for joining the wall structure of the converted wooden building and the heat insulating panel 10 using screws or the like.

10 is a horizontal cross-sectional view of the column 16 in FIG. 8, and FIG. 11 is a vertical cross-sectional view of the column 16 in FIG. A description will be given below of a wall of a wooden building in which the heat insulating panel 10 is used. Before the construction of a wooden building using the heat insulation panel 10, the bottom plate of the wall including the load-bearing wall of the wooden house is constructed using the load bearing face material 18 such as a structural plywood or a structural panel. Are arranged vertically or horizontally with respect to the pillars of the wooden building so that the building surface material 10 which is a component becomes the front.

The screws 16 are passed through the small holes 12 on the rear heat insulation panel 10 and the butted portions are brought into close contact with each other so that there is no gap between the heat insulation panel bodies. The pillars 16 and 18 in FIG. 10, the base 15 in FIG. By fixing to the shaft assembly, a heat insulating layer made of the resin foam 12 is constructed outside the wall shaft assembly. 10 and 11 are illustrations of an embodiment, and the case where the heat insulating panel is vertically attached to the column as shown in FIG. 9 is slightly different from the figure.

After the heat insulation panel is fixed to the wall, the surface treatment material 20 containing an organic solvent is applied to the entire wall surface constructed with the heat insulation panel. FIGS. 12 to 14 which are enlarged views of the frame E in FIG. 10 show a process in which the sealing recess 21 is formed in accordance with this work. Part of the organic foam heat insulating material 13 that protrudes from the building surface material 11 by application of the surface treatment material 20 is dissolved in an organic solvent, and a groove 22 is formed in the protruding portion 14 of the resin foam. Further, the surface treatment agent 20 has an effect of increasing the affinity with the amorphous sealing material 22. Thereafter, a modified silicone-based or elastic rubber-based irregular sealing material 22 is poured into the sealing recess 21 formed on the heat insulating panel and cured, and the exterior is finished by a painting operation.

The construction surface material 10 constituting the heat insulation panel 14 according to the present invention will be described with reference to FIG. For the sake of explanation, small holes are attached to the small holes 11 with reference numerals, and the same small letters are attached to the small holes in the same row. In consideration of the fact that the building surface material 10 is used as the base of the outer wall, and the heat insulation panel is assumed to be constructed on a wooden building standardized by a shaku module, it is 900 mm wide, 1810 mm long, and thick. A ceramic face plate such as a fiber reinforced cement board having a diameter of 4 mm is used, and a small hole 11 is drilled in this. The space between the holes, which are the same attached letters, is 420 mm, the distance between the rows with the same attached letters is between row a and row b, and row d. The distance between rows e is 420 mm, the distance between rows b and c, and the distance between rows c and d is 455 mm. The perforated small holes 11 serve to simplify the perforating work of the building surface material at the construction site, and function as a mark of a screw in accordance with the standard of the house.

The numerical values described are in accordance with the shank method generally used in the wooden frame construction method. When the standard of the heat insulation panel is adapted to other building modules such as a meter module, the building surface material 10 and It is conceivable to change the size of the resin foam 12, the number of small holes 11, or the interval between the small holes 11, and one example thereof is shown in FIG. The case of FIG.

In FIG. 2, the resin foam 12 constituting the product of the present invention in combination with the building surface material is a polystyrene heat insulating plate having a length and width larger than that of the building surface material 10, and in this case, the width is 910 mm and the length is 1820 mm. An extruded polystyrene foam insulation board having a thickness of With the resin foam 12 and the perforated building surface material 10 aligned with one end in the length direction and the width direction as shown in FIG. 2, an adhesive that does not corrode the resin foam such as EVA is used. Both are adhered, and a resin foam protruding portion 14 having a width of 10 mm is provided at either one of the left and right ends and one of the upper and lower ends. A perspective view of the heat insulation panel body is shown in FIG. 2, and a front view and a sectional view are shown in FIGS. 3 to 5. As shown in FIGS. 4 and 5, since the heat insulating material 12 itself is not perforated, damage to the heat insulating material due to an installation error in the field is suppressed.

As shown in FIG. 2, the small holes 12 processed in the heat insulation panel are standardized at regular intervals according to the module of the wooden building. In this embodiment, the total number of small holes on the building surface material 10 is 15, but this numerical value is based on the premise that the completed heat insulation panel is to be installed in a modular house with a stud. The small hole 11 in the heat insulation panel 14 is set at a position where a nail or a screw can be fixed to the shaft assembly including the pillar 16 even when the heat insulation panel 14 is arranged in either the vertical or horizontal direction. In contrast, it can be installed in either vertical or horizontal orientation.

The following examples are explanations related to a wall of a wooden building using the heat insulating panel 10. Before using the insulation panel 10 to construct the wooden house as shown in Fig. 8, construct the wall structure including the load-bearing wall of the wooden house, and install a drainer to cover the foundation from the outdoor side of the structural frame To do. The heat insulating panel body 10 is arranged side by side in the vertical or horizontal direction so as to be aligned with the opening so that the building surface material 11 becomes the front. Then, as shown in FIG. 9 and FIG. 10, the screws 21 are passed through the small holes 12 formed in the building surface material 11, and the insulation panel is pressed and insulated so as not to cause a gap between the insulation panel bodies as much as possible. As shown in FIG. 10 and FIG. 11 which is an enlarged view thereof, the materials are bonded to each other using the screws corresponding to the panel thickness as shown in FIG. The joined screws are joined at the center in the inter-column 20 and in the column 16 which is usually 105 mm in width at a location 30 mm or 40 mm away from the center.

After the heat insulation panel is joined to the wall, a surface treatment material 22 such as a paint primer containing an organic solvent is applied to the entire wall surface on which the heat insulation panel 10 is constructed. The process of forming the recess for sealing with this work is shown in FIGS. 12 to 14 which are enlarged views of the E frame in FIG. Part of the organic foam heat insulating material 13 that protrudes from the building surface material 10 by application of the surface treatment material 22 is dissolved in the organic solvent contained in the surface treatment agent, and the resin foam protrusion 13 is 2 mm deep. Then, the recess 23 shown in FIG. 13 is formed by chemical cutting over 3 mm. The depth of the concave portion 21 from the surface of the building surface material 11 is 6 mm to 7 mm when combined with the surface material thickness of 4 mm, which is a sufficient depth for the sealing material to exert its effect. This surface treatment agent 20 itself has the effect of increasing the affinity between the sealing material 22 and the recess 21 and also the affinity between the sealing material 22 and the recess 21 by forming a dense surface of the resin foam by defoaming. Is even higher. Thereafter, the amorphous sealing material 22 is poured into the recess 23 and hardened to completely fill the gap between the heat insulating panels 14. The sealed wall surface is completed by applying exterior finishing such as painting or mortar.

As shown in FIG. 7, a ceramic-based face material 10 such as a fiber reinforced cement board having a width of 900 mm, a length of 1810 mm, and a thickness of 4 mm and a resin foam 12 having a width of 910 mm and a length of 1820 mm having an arbitrary thickness are bonded to each other. An example is given in which the resin foam 12 is provided with protruding portions having a width of 5 mm on the top, bottom, left, and right sides of the resin foam 12. The construction procedure for fixing the heat insulation panel to the wall is the same as that of the first embodiment, but the joining position of the screw 19 in FIGS. 9 and 10 is different from that of the heat insulation panel of the first embodiment. After fixing to the wall structure, the surface treatment agent 20 is applied in the same manner as in Example 1 to dissolve the protruding portion 14 of the resin foam and form a recess 22 for sealing.
