Description

  The present invention relates to a housing structure excellent in heat insulation, ventilation and ventilation of a roof, walls and floors in a house.

Current methods of heat insulation of wooden houses are roughly divided into inner insulation (filling insulation) and outer insulation (outer insulation). Internal heat insulation is a method of applying heat insulation between pillars and walls of a structural frame, and rock wool or glass wool is generally used as the heat insulation. Outer heat insulation is a method of applying a heat insulating material to the outside of a structural housing, and polystyrene foam or urethane foam is used as a heat insulating material (see Patent Document 1).
JP 2000-55291 A

  However, the conventional insulation methods for wooden houses have the following problems.

1. In the case of the inner heat insulation method (1) Since there is a heat insulating layer inside, the volume in the heat insulating layer is small and easy to warm and cool, but rock wool and glass wool used as heat insulating materials are easily affected by the outside air because of their small heat capacity.

(2) Since rock wool and glass wool are low in air tightness and easy to pass moisture, if there is a large temperature difference from the outside air, internal condensation tends to occur.

(3) When rock wool or glass wool is used, the sound absorption is high, but the sound insulation is low.

2. In the case of the outer insulation method (1) Styrofoam and foamed urethane are highly airtight and difficult to pass through moisture, so even if the temperature difference from the outside air is large, it is difficult to cause internal condensation. I can say that.

(2) When foamed polystyrene or foamed urethane is used, the sound insulation is high but the sound absorption is low.

(3) Because it is a basic heat insulation, the room is susceptible to the effects of antiseptic and ant protection agents.

  Therefore, the present invention provides a residential structure that is free from the problems of conventional heat insulation methods and that is comfortable and easy to live in and has excellent heat insulation, ventilation, and ventilation.

  In the present invention, the foundation is a solid foundation and a ventilation method using a steel bundle and foundation packing.

  For the foundation, use a grade that is resistant to corrosion and ant damage such as firewood. All wood is made of dry wood or laminated wood to make up the frame. Then, airtight construction is performed on the outside of the housing with an airtight sheet or the like, and a heat insulating material such as urethane foam is attached to provide external heat insulation. When finishing the outer wall material and roofing material, a trunk edge is constructed on the base, and an integrated ventilation layer is provided through the foundation to the ridge.

  Next, a fibrous heat insulating material such as rock wool or glass wool is attached to the inside of the housing so as to wrap the room, thereby providing internal heat insulation. At this time, it is constructed so that a space is formed between the outer heat insulating material and the inner heat insulating material, and an air layer is formed between the outside air and the inside air.

A total heat exchange type 1 ventilation system that operates 24 hours a day is installed in the room to adjust the temperature and humidity in the room. In addition, the air exhausted from the ventilation system to the outside is once exhausted to the air layer between the heat insulating materials, and then the air in the air layer is exhausted to the outside by the third type ventilation system installed on the back of the ceiling / shed. Let

  The present invention performs both heat insulation of the outside heat insulation and the inside heat insulation, and also provides an air layer between the heat insulation materials, softens the temperature difference between the outside air and the inside air, and can prevent internal condensation by ventilating, and has an airtightness. Air pollution that may occur due to the high can be eliminated by a total heat exchange type 24-hour ventilation system.

  In addition, by adopting a vent between the foundation and the foundation, it is possible to suppress the effect of the antiseptic / anticides on the interior of the room, and in addition to this, by using a grade such as firewood for the foundation Corrosion and ant damage can be suppressed without using antiseptic and ant protection agents. Furthermore, by providing an integral ventilation layer on the finishing base, it is possible to suppress deterioration of the member due to stuffiness and to reduce the change in the body temperature due to radiant heat from the finishing material.

    According to the present invention, it becomes a house that is easy to warm and difficult to cool, or that is easy to cool and difficult to warm and has high heat insulation performance. And by providing an air layer and a ventilation system, it was possible to prevent internal dew condensation, which was a disadvantage, and to make the room suitable for the human body throughout the year. Moreover, since the application of the medicine can be eliminated by adopting a vent hole between the foundation and the base, there is no influence on the human body, and further deterioration of the member can be suppressed by aeration. In addition, as a feature of the heat insulation used, heat insulation such as urethane foam has sound insulation, and fiber insulation such as rock wool has sound absorption, so it blocks noise from outside and absorbs sound from the room. It has the effect of soundproofing.

  FIG. 1 is a sectional view showing the whole house and ventilation and ventilation of the present invention, FIG. 2 is a sectional view of the floor, FIG. 3 is a sectional view of the roof, and FIG. 4 is a sectional view of a wall of the same body. .

  In FIG. 1, the foundation 1 is a solid foundation. The foundation internal rise 2 is a base width, but as shown in FIG. 2, the rise 2 of the outer peripheral portion of the foundation 1 is increased to the outside in consideration of the thickness of the heat insulating material. Surfaces that are finished on the same street as the outer walls of terrace pillars and porch pillars will also be increased.

  In FIG. 2, the base 3 is made of eaves and the like, and the bundle is made of steel, and the base 3 is supported via a plurality of base packings 4 arranged at intervals on the rising 2, and adjacent base packings are supported. A floor ventilation passage is formed by ventilating the gap between the four through the vent.

  The shaft is built by combining horizontal materials such as columns and vertical materials such as beams by conventional shaft construction methods. Use dry or laminated wood for all structural materials. This is to prevent gaps and deviations from being generated in the heat insulating material due to shrinkage of the wood, and to prevent internal condensation caused by evaporation of moisture contained in the wood.

  3 (a) and 3 (b), when processing the structural material of the roof portion, the upper end of the rafter 5 and the upper end of the corner tree are generally processed at the same height, but in the present invention, the rafter is more than the corner tree. It is processed to be about 15mm higher. In this way, a ventilation layer 7 can be formed which passes from the rafter 5 to the corner tree.

  The heat insulating method of the roof part is a method of dropping plate-like foamed urethane between the rafters 5 as the heat insulating material 8. The rafter 5 is a dry material and has a size that is 20 mm or more larger than the thickness of the heat insulating material used for the roof.

  When the heat insulating material 8 is dropped, the heat insulating material 8 is firmly dropped and is constructed so that a step is formed due to the difference in thickness between the rafter 5 and the heat insulating material 8. If it carries out like this, the ventilation layer 7 which escapes from a eave to a purlin and a purlin can be formed on the heat insulating material between rafters. Moreover, when dropping the heat insulating material 8, in order to take airtightness inside, it is made not to make a clearance gap. When a gap is formed, the heat insulating material 8 is filled to obtain airtightness. If a factory-cut product is used for the heat insulating material 8 used at this time, construction accuracy and construction efficiency can be increased, and dust on the site can be reduced.

  When constructing the roof base (field board 9, asphalt roofing 10), the ridge is not pasted up to the end, leaving a gap so that the air in the ventilation layer 7 can escape to the ventilation tiles 11. 12 is a roof tile.

  As shown in FIG. 3 (c), the base of the lower house (the base plate 9, the asphalt roofing 10) is not stuck up to the wall, and is finished with a gap corresponding to the thickness of the heat insulating material 13 on the outer wall and the outer wall trunk edge. If it carries out like this, the air which went up the ventilation layer 7 between rafters will be finally discharged | emitted from the ventilation layer 7 of the ridge part from the ventilation layer 7 of the heat insulating material 13 of an outer wall to the outdoors from the building ventilation crosspiece 11. FIG.

  In FIG. 4, before constructing the outer wall heat insulating material 13 on the outer periphery of the housing, an airtight sheet 14 is pasted on the outer peripheral surface of the housing. At this time, if the inside is not dried to some extent, it causes condensation. Further, the airtight sheet 14 is wound as a base for attaching the sash 15 to prevent dew condensation.

  After completion of the airtight sheet construction, a plate-like urethane foam heat insulation material is applied to the outer wall portion as the heat insulation material 13 of the outer wall. A trunk edge receiver 16 having the same thickness as that of the heat insulating material 13 on the outer wall is driven from the lower end of the base 3 to the second floor girder at intervals (see FIG. 2). In addition, the same trunk edge holder is also applied around the outer opening. At this time, a dry one is used as the trunk edge receiver 16. Then, a heat insulating material is fitted and pressed by the trunk edge so that there is no gap between the trunk edges. If there is a gap, fill with urethane foam. If factory-cut products are used for the heat insulating material used at this time, construction accuracy and efficiency can be improved, and on-site garbage can be reduced. Then, a moisture permeable waterproof sheet 18 is pasted on the ventilator rim 17 to construct an outer wall material (siding) 19.

  Returning to FIG. 2, the floor heat insulating method is construction in which urethane foam is dropped between the joists 21 as the floor heat insulating material 20. The joist 21 is a drying material, and the floor insulation 20 is the same thickness as the joist spine. In this way, it is possible to prevent the air under the floor from flowing into the wall through the gap between the base 3 and the joists 21. If the structural plywood 22 and the flooring 23 are constructed on this, the floor portion can be airtight. However, if the floor is insulated by this method, the bathroom cannot be insulated, so only the bathroom part will be the basic insulation.

  In FIG. 4, the heat insulating material 24 of an inner wall is formed with rock wool as a fibrous heat insulating material. The rock wool 24 in the wall is attached to the indoor side so that an air layer 25 is formed between the outer wall and the heat insulating material 13. Normally, the rock wool 24 in the wall is constructed to the bottom of the beam, but as shown in FIG. 3 (b), in this case, the construction is performed up to the ceiling so that the air in the wall can escape to the back of the shed and the ceiling. To. Rock wool 24 is also constructed on the back of the ceiling, and is structured so as to be integrated with the rock wool 24 attached to the wall so as to wrap the indoor portion.

  As shown in FIG. 1, a total heat exchange type 1 ventilation system 26 that is always in operation for 24 hours is installed in the room. At the back of the shed and the ceiling, the third type ventilation system 27 that is always in operation is installed. The exhaust of the first type ventilation system 26 is not directly discharged to the outside, but is exhausted to the back of the shed and the ceiling, and to the outside as the air of the back of the shed and the ceiling by the third type ventilation system 27 attached to the back of the shed and the ceiling. Discharge.

  The present invention has excellent heat insulation performance, prevents internal condensation, makes the room suitable for the human body throughout the year, has no effect on the human body, can further suppress deterioration of the members, and from outside the room. It can be used as a house where noise can be cut off and soundproofed.
