Description

  The present invention relates to a heat insulation renovation method for an existing wall and a heat insulation renovation method for an existing building, and can mainly reinforce a wall of an existing wooden house at low cost and in a short construction period.

  Even if the performance of the air conditioning equipment is excellent, if the heat insulation performance of the building that is the container is inferior, a sufficient air conditioning effect cannot be achieved, and a comfortable living space cannot be provided. In addition, energy loss is large, and running costs for air conditioning are increased.

  For this reason, in recent years, there is a problem such as global warming, which is becoming more serious, and there is an increasing tendency to insulate and renovate existing wooden houses such as old private houses in order to use energy efficiently.

  By the way, conventionally, heat insulation of an outer wall of a wooden building is generally performed by a filling heat insulation method in which a hollow portion formed between an exterior material and an interior material is filled with a nonflammable heat insulation material such as glass wool. In addition, in many cases, heat insulation is installed on the floor and roof together with the outer wall to make the entire building a heat insulating structure.

  In this case, heat insulation of the floor is generally performed by filling a heat insulating material between the joists of the floor set, and heat insulation of the roof is performed by filling the heat insulating material between the rafters of the roof set. For this reason, when the existing wooden building is heat-insulated and repaired by installing a heat insulating material on the wall or floor, the above-described filling heat insulating method is used.

  However, if it is necessary to insulate and renovate existing walls, for example, by filling insulation methods, it is necessary to tear down some of the walls such as exterior materials and fill the cavities with thermal insulation, and then finish the demolished parts again There was a problem that the construction was large and the construction cost increased.

  Moreover, if insulation is installed on the floor and roof together with the outer walls to insulate and renovate the entire building, the construction will not only become larger, but the construction period will be longer and the construction cost will be considerably increased.

  Furthermore, in the case of a large wooden house such as an old private house, each room is generally large, and the partition walls that divide the room have a structure in which the outside air flows from under the floor to the attic. However, there was a problem that the construction cost was one-handed and only the construction cost increased, and sufficient heating and cooling effects could not be obtained.

  In addition, the family structure and lifestyle have changed due to the progress of the nuclear family, and even if the whole building is insulated, it is wasteful and unfit for the substance. There is a growing demand for private room insulation.

  The present invention has been made in view of such problems and the present situation, and is a heat insulation renovation of an existing wall and a heat insulation refurbishment method for an existing building which can be performed in a short period of time and at low cost for heat insulation renovation of an existing wooden building. The purpose is to provide.

The heat insulation repair method for an existing wall according to claim 1 is characterized in that a plurality of horizontal trunk edges are provided on a wall surface of an existing wall having a large wall structure in which the pillar is not exposed to the outside of the wall surface by arranging the pillar in the wall surface. Attaching a vacuum heat insulating material formed into a rectangular plate shape between the horizontal torso edges at predetermined intervals, and installing the wall finishing material on the vacuum heat insulating material. A fin piece having a leaf spring function that presses the side surface of the horizontal trunk edge around the vacuum heat insulating material is projected, and a vacuum heat insulating material is attached between the horizontal drum edges by the leaf spring function of the fin piece, and the horizontal trunk A fastener that is rotatable along the surface of the vacuum heat insulating material is attached to the edge, and the vacuum heat insulating material is fixed by projecting the metal stopper onto the vacuum heat insulating material.

  The present invention makes use of existing walls as they are without breaking them down, and installs a vacuum insulation material on the existing walls, and newly installs a wall finishing material on the existing walls. It can be done at a low cost.

  As the vacuum heat insulating material, for example, a vacuum heat insulating material formed into a rectangular plate having a standard size by vacuum packing an existing heat insulating material such as glass wool with a packing film made of an aluminum composite film or the like can be used.

  Since the vacuum heat insulating material is evacuated, heat conduction does not occur and a large heat insulating effect can be ensured, so that the vacuum heat insulating material can be formed quite thin. For this reason, even if it installs on the existing wall surface, the wall does not become thick and the room does not become extremely narrow. Moreover, the heat insulation effect can also be heightened by installing doublely as needed.

  In this case, if a cylinder edge with a thickness of about 15 mm is used and a vacuum insulation with a thickness of about 7 mm is used, the existing wall is insulated by installing two vacuum insulation materials between the cylinder edges. Insulation can be renovated without difficulty on high-performance walls.

  By the way, the vacuum heat insulating material not only maintains the heat insulation effect for a long time, but also breaks the vacuum when the hole is opened in the packaging film for vacuum packing the heat insulating material, or the heat insulation performance is not maintained for a long time. Since a packaging film made of steel may cause electric rust when it is in contact with a steel nail for a long period of time, it is not preferable to attach the vacuum heat insulating material by tucking nailing so that a hole is opened in the packaging film.

  The present invention can be easily attached by pressing and fitting the vacuum heat insulating material between the trunk edges. In this case, either the horizontal trunk edge or the vertical trunk edge may be used. In particular, the horizontal trunk edge is temporarily fixed by placing the vacuum heat insulating material on the horizontal trunk edge. In the meantime, the vacuum heat insulating material can be installed so as not to fall on the existing wall surface.

  In addition, a fin piece having the function of a leaf spring is provided around the vacuum heat insulating material, and this fin piece is folded into the inner side of the body edge, and the vacuum heat insulating material is fitted between the body edges to ensure a vacuum. Thermal insulation can be installed.

  In addition, the vacuum heat insulating material sandwiches the heat insulating material processed into a rectangular plate shape between two packing films cut into a rectangular shape, and thermally welds the peripheral portions of the two packing films into a bag shape. It can be formed by sealing and evacuating the inside, and the peripheral portion of the thermally welded film can be a fin piece having the function of a leaf spring.

  In addition, the vacuum insulation is fitted between the barrel edges and held by a belt-shaped resin fixture formed so as to straddle between the barrel edges, so that the vacuum insulation is not damaged between the barrel edges and is detached. It can be installed securely so that it does not (see Fig. 4 (a), (b)).

  Furthermore, a method in which a vacuum heat insulating material is fitted between the drum edges, and a resin tape is continuously laid between the drum edge and the vacuum heat insulating material, and nail to the drum edge with a tucker nail, etc. The vacuum heat insulating material can be securely installed so as not to be damaged and detached.

  The heat insulation renovation method for the existing wall according to claim 2 is the heat insulation renovation method for the existing wall according to claim 1, wherein a normal heat insulating material is attached instead of the vacuum heat insulating material in the vicinity of the ceiling, floor and / or around the window. It is characterized by.

  In the present invention, the heat insulation performance of the entire wall can be maintained at a high level by appropriately using the vacuum heat insulating material and the normal heat insulating material according to the wall conditions. In the case of a residential room, generally, an outlet is attached near the floor of the entrance / exit, and a switch for lighting is attached near the hand. Therefore, it is necessary to provide a hole for attaching a plate in these portions.

  In addition, dimensional deviations that occur during the process of attaching wall materials are generally corrected near the floor or near the ceiling, and wall material installation around windows and near entrances depends on the size of the room. Are generally troublesome work.

  In the case of the present invention, the vacuum heat insulating material is processed by attaching a normal heat insulating material such as hard urethane foam to an appropriate size in place of the vacuum heat insulating material, in particular, near the ceiling, near the floor, and around the window and the entrance and exit. It is possible to construct a wall having a high thermal insulation performance without damaging the entire wall. Moreover, since one type of vacuum heat insulating material can be used in size, the workability is good and the construction can be performed at low cost.

  A heat insulation renovation method for an existing wall according to claim 3 is the heat insulation renovation method for an existing wall according to claim 1 or 2, wherein a protective plate for protecting the vacuum heat insulation material is provided on the vacuum heat insulation material at a position where a thumbtack is applied. It is characterized in that it is attached in a stacked manner.

  Depending on the room, it may be desirable to decorate the room by attaching a poster or the like to the wall. However, if the poster is fastened to the wall with a thumbtack, the vacuum heat insulating material may be damaged by the thumbtack and the heat insulation performance may be reduced. In such a case, there is no problem if the thumbtack is hit by aiming at the torso edge, but it is also difficult to hit the thumbtack on the torso edge having a width of about 45 mm due to the size of the posters.

  According to the present invention, it is possible to prevent the vacuum heat insulating material from being damaged by the thumbtack by attaching the protective plate on the vacuum heat insulating material, particularly at the position where the thumbtack is applied for attaching posters. For example, a hard polypropylene plate can be used as the protective plate.

  Since the length of a general thumbtack needle is about 11 mm, if a plaster board with a thickness of 9.5 mm is used as a wall material, a protective plate with a thickness of 3 mm is overlaid on the vacuum heat insulating material and attached by a thumbtack. It is possible to prevent the vacuum heat insulating material from being damaged.

  The heat insulation repair method of the existing wall of Claim 4 is a heat insulation repair method of the existing wall in any one of Claims 1-3, The resin-made fixing tool for hold | maintaining a vacuum heat insulating material between horizontal trunk edges is used. It is characterized by being attached.

  According to the present invention, the vacuum heat insulating material installed by being fitted between the lateral trunk edges can be securely fixed without damaging and not being detached from between the trunk edges.

  As a resin fixture in this case, for example, there are ones that are formed in a band shape so as to straddle between the trunk edges, and locking claws for locking to the trunk edges are formed at both ends.

  According to the present invention, the vacuum heat insulating material can be fixed between the barrel edges with a single touch, and since the vacuum heat insulating material is not damaged, the heat insulating performance can be maintained.

  The present invention is an extremely economical method for heat insulation repair of existing wooden buildings by attaching heat insulation to the walls, floors and ceilings of the rooms and renovating the insulation for each room or multiple rooms. It was made to be able to go to.

  In particular, in the case of large wooden houses such as old private houses, each room is generally large, and the partition walls that divide the room have a structure in which the outside air flows from under the floor to the attic. However, it is very easy to renovate large existing wooden buildings in a very economical manner in a short period of time. Can do.

  In this case, the floor and the ceiling can be heat-insulated and repaired by a conventional filling-type heat-insulating method, but can also be performed in the same manner as the heat-insulating repair method according to claim 1.

  That is, the floor insulation is improved by attaching a plurality of joists to an existing floor surface at predetermined intervals, attaching a vacuum insulation between the joists, and newly installing a floor finish on the vacuum insulation. be able to.

  In addition, heat insulation of the ceiling is performed by attaching a plurality of field edges to the ceiling surface at predetermined intervals, attaching a vacuum insulation material between the field edges, and newly installing a ceiling finishing material on the vacuum insulation material. Can do.

  The joist and the field edge are alternatives to the trunk edge, and the function is the same as that of the trunk edge in such a way that the cross-sectional dimension is different from that of the trunk edge.

  The present invention makes use of existing walls without breaking them, attaches a vacuum heat insulating material on the existing wall, and newly installs a wall finishing material on the existing wall, so that the heat insulation of the existing wall can be repaired extremely easily and at low cost. It has the effect that it can be performed.

  Further, since the vacuum heat insulating material is fitted between the body edges and attached, the vacuum heat insulating material can be easily attached.

  Furthermore, since the heat insulation of the vacuum heat insulating material does not occur and a large heat insulating effect can be secured even if it is thin, the room is not extremely narrowed even if it is installed on the existing wall surface.

  In addition, since insulation is installed on the wall surface on the indoor side, the insulation for each room can be improved by installing insulation on the indoor side of the floor and ceiling. By this, existing large wooden buildings such as old private houses can be insulated and repaired very economically and without waste.
