Description

  The present invention relates to a technique for attaching a heat insulation panel to an outer wall.

  In the frame construction method in which beams are installed between column members, it is common to install wooden beams between wooden column members. Using wooden pillars and wooden beams in this way has the advantage that the torso and other members can be easily fixed with a fastener such as a nail. The strength is weaker than that used.

  Therefore, conventionally, a beam formed by fixing a wooden plate material to the upper surface of the upper flange portion and the lower surface of the lower flange portion of the H-shaped steel is constructed between the wooden column members. This has the advantage that the strength can be increased at the same time while taking advantage of the wooden structural material.

  For example, Patent Document 1 is known as such a conventional example.

  In the above conventional example, a heat insulating material is incorporated and attached in the outer wall, but the heat insulating material is fitted with a plate-shaped heat insulating panel in a portion surrounded by the beam and the column material. However, in the above-mentioned conventional example, there is a problem in that heat is not provided in the beam portion, and heat is escaped in and out of the building in the beam portion. In particular, heat is escaped in the H-shaped steel portion of the beam. There is a problem.

  Therefore, although it is necessary to insulate the H-shaped steel portion of the beam, it is conceivable to attach a heat insulating material separate from the heat insulating panel between the upper and lower flange portions of the H-shaped steel.

However, in this construction, a plate-like heat insulation panel is fitted and attached to a portion surrounded by the beam and the column material, and a heat insulation material is fitted between the upper and lower flange portions of the H-shaped steel. There is a problem that it is a separate work from the work, and it takes time and effort. Moreover, the outer end of the flange part of the H-shaped steel remains exposed, and this part becomes a thermal bridge and heat is released. There's a problem.

  The present invention was invented in view of the above-described conventional problems, and can perform heat insulation work on the H-shaped steel part of the beam and heat insulation work on the part between the pillars of the outer wall simultaneously and reliably. At the same time, it is an object of the present invention to provide a method for mounting a heat insulating panel on an outer wall that can simplify the construction.

  In order to solve the above-described problems, the method of attaching the heat insulation panel on the outer wall according to the present invention is to fix the wooden plates 4 and 5 to the upper surface of the upper flange portion 2 and the lower surface of the lower flange portion 3 of the H-section steel 1 respectively. The beam 6 constructed in this manner is laid between the wooden pillars 7, and a heat-insulating panel 10 is formed by integrally projecting a heat-insulating protrusion 9 for fitting the beam into the upper part on one side of the plate-like plate-like heat insulating part 8. The heat insulation projection 9 for fitting the beam of the heat insulation panel 10 is fitted between the upper and lower flange portions 2 and 3 on the outdoor side of the H-shaped steel 1 of the beam 6 to temporarily hold the heat insulation panel 10, and then heat insulation A body rim 11 is arranged on the surface of the panel 10 on the outdoor side, and the heat insulating panel 10 is fixed to the column member 7 together with the body rim 11 by a fixing tool 12.

  By adopting such a method, using the H-section steel 1 portion constituting the main body of the beam 6, the heat-insulating protrusion 9 for fitting the beam of the heat-insulating panel 10 is placed on the outdoor side of the H-section steel 1 of the beam 6. The heat insulating panel 10 is temporarily held by being fitted between the upper and lower flange portions 2 and 3, and the heat insulating panel 10 can be fixed to the wooden column 7 together with the trunk edge 11 by the fixing member 12. The heat insulation construction of the shape steel 1 and the heat insulation construction of the portion between the column members 7 of the outer wall can be performed simultaneously. Moreover, since the heat insulation of the H-section steel 1 of the beam 6 and the heat insulation of the portion between the column members 7 of the outer wall can be continuously performed by the heat insulation panel 10, in particular, the end portion of the flange portion 3 below the H-section steel 1 is provided. Covering with the heat insulation panel 10, it is possible to reliably prevent heat from escaping by the thermal bridge at this portion, and to ensure airtightness.

  Since the present invention is constructed by the method as described above, the heat insulation construction of the H-shaped steel portion of the beam and the heat insulation construction of the portion between the pillars of the outer wall can be performed reliably and easily. In addition, the heat insulating property and the air tightness can be improved.

  Hereinafter, the present invention will be described based on embodiments shown in the accompanying drawings.

  The beam 6 is configured by fixing wooden plates 4 and 5 to the upper surface of the upper flange portion 2 and the lower surface of the lower flange portion 3 of the H-section steel 1, and the beam 6 is formed between the wooden column members 7. A shaft assembly structure 15 is formed as shown in FIG.

  In addition, the wooden pillar material 7 as used in the field of this invention is the concept containing not only the pillar 7a but the space | interval pillar 7b. In the figure, reference numeral 20 denotes a foundation, 21 denotes a base, and the column 7 is erected on the base 21.

  FIG. 6 shows a heat insulating panel 10 used in the present invention. A heat-insulating protrusion 9 for fitting a beam is integrally formed on the upper part on one side of a plate-shaped heat insulating part 8 in the left-right direction. The heat insulation panel 10 is configured.

  Here, the heat-insulating protrusion 9 for fitting the beam is surrounded by one half in the width direction of the upper flange portion 2 of the H-shaped steel 1 of the beam 6, one half in the width direction of the lower flange portion 3, and the web portion 13. The size is such that it fits snugly into the recess 14 that opens outward. The vertical length of the heat insulation panel 10 is, for example, the length from the upper flange 2 to the base 21, and the length in the left-right direction is, for example, the distance between the centers of the column members 7 (in the embodiment, the column The distance between the centers of 7a).

  In order to form the outer wall in which the heat insulating panel 10 having the above-described configuration is incorporated in the shaft assembly 15 described above, it is performed as follows.

  First, as shown in FIG. 2, a base plate 16 such as a plywood is fixed to the outer surface of the column member 7, and the upper end portion of the base plate 16 is fixed to the lower surface of the flange portion 3 below the beam 6. It adheres to the outer end face of the lining. In the embodiment, the base plate 16 is fixed, but the step of fixing the base plate 16 may be omitted.

  Next, as shown in FIG. 3, the heat-insulating protrusion 9 for fitting the beam of the heat insulating panel 10 is fitted into the concave portion 14 of the H-shaped steel 1 of the beam 6 from the outdoor side to temporarily hold the heat insulating panel 10.

  After that, as shown in FIG. 4, the trunk edge 11 is arranged on the outdoor side surface of the heat insulation panel 10, and the heat insulation panel 10 is fixed to the pillar material 7 together with the trunk edge 11 by a fixing tool 12 such as a screw. .

  In this way, once the heat-insulating projection 10 for fitting the beam of the heat-insulating panel 10 is temporarily fitted into the concave portion 14 of the H-shaped steel 1 of the beam 6 from the outdoor side, the heat-insulating panel 10 is temporarily held, and then together with the trunk edge 11 Since the heat insulation panel 10 can be fixed to the main body, the area of the heat insulation panel 10 is large, so that it is difficult to handle at the time of work, and it is difficult to position and fix the heat insulation panel 10. Even so, it is possible to easily fix the heat insulating panel 10 having a large area and the trunk edge 11 to the column member 7 at the same time. Moreover, since the heat insulation construction of the H-section steel 1 of the beam 6 and the heat insulation construction of the portion between the column members 7 of the outer wall can be performed at the same time, the construction for heat insulation can be further simplified.

  After fixing the heat insulation panel 10 and the trunk edge 11 to the column member 7 as described above, the exterior member 17 is attached to the outer surface side of the trunk edge 11 as shown in FIG. Form the outer wall.

  In the outer wall formed as described above, the heat insulating panel 10 incorporated therein is continuously present from the H-shaped steel 1 portion of the beam 6 to the portion between the column members 7 of the outer wall. The heat insulation of the H-section steel 1 and the heat insulation of the portion between the column members 7 of the outer wall can be continuously performed by the heat insulation panel 10, so that the heat insulation effect is improved and the airtightness is improved.

  In this case, since the heat insulation of the H-section steel 1 part is further insulated by the thick heat-insulating projection 9 for fitting the beam, the end of the flange portion 3 below the H-section steel 1 is also covered with the heat insulation panel 10. The heat bridge can surely prevent the heat from escaping, and the heat insulation effect is improved in this respect as well.
