Description

[Technical field]

[0001] The present invention relates to an insulating panel that constitutes the walls of buildings, and in particular to a wall insulating panel that can be easily constructed to be airtight by attaching insulating material to the facing material that constitutes the walls of buildings and inserting it between pillars. [Background technology]

[0002] Conventionally, various structures for constructing walls of buildings have been developed, and various wall structures that have a heat insulating effect and are easy to install have been developed and are in use. The walls of buildings are usually equipped with heat insulating materials, which makes it possible to minimize the influence of the outdoor temperature and keep the indoor temperature constant.

[0003] Since the insulation is to be installed between each pillar, the insulation is cut to fit the width of the pillars and then installed on the wall after the facing has been installed. With this configuration, it may be necessary to process the insulation on-site, which is inefficient.

[0004] For example, Japanese Patent Application Laid-Open No. 2001-011969 discloses a technique for constructing a wall of a building by installing a heat insulating material. This technique involves forming an inclined surface on the outer periphery of a wall panel that is arranged between the framework of a wooden house and is made of a plate-like body and a heat insulating material, as a wall panel that allows the heat insulating material to be easily fitted into the framework.

[0005] This technology certainly makes it possible to easily fit insulation into the framework, but there is a problem in that there is a lot of work to be done before fitting it in at the construction site, and the improvement in work efficiency is insufficient. Also, there is a major problem in that the chamfering on the interior side makes the airtightness insufficient, making it impossible to form an air circulation mechanism that circulates air inside the wall and keeps the temperature inside the room constant.

[0006] As a device for air conditioning equipment in buildings, there is a configuration in which an air flow panel with an air flow layer is installed on the wall surface of a building, but if the sealing by the insulation material is insufficient, condensation etc. occurs in this air flow layer in the wall or between the insulation material and the wood, which causes mold to grow, and the wood to rot or become damaged, etc. Therefore, there has been a demand for the development of a wall insulation panel with an air flow layer in the wall that can easily insert the insulation material between pillars while ensuring sufficient airtightness when inserting the insulation material.

[0007] [Patent Document 1] JP 2001-011969 A DISCLOSURE OF THEINVENTION [Problem to be solved by the invention]

[0008] In order to solve the above problems, the present invention aims to provide an insulation panel that constitutes the walls of a building, and in particular, to provide a wall insulation panel that has an air gap within the wall that enables ventilation within the structure, while ensuring sufficient airtightness when installing insulation material between walls, and allows insulation material to be easily installed between pillars. [Means for solving the problem]

[0009] In order to achieve the above-mentioned object, the wall insulation panel of the present invention is a wall insulation panel consisting of a cubic face material and a cubic insulating material attached and fixed to the face material, which is intended to be inserted between the pillars of a building to provide insulation and fixation, and the face material consists of a fixing portion formed with a constant width on each indoor side of the face material for attaching it to the pillar of the building, and an attachment portion formed inside the fixing portion for attaching and fixing the insulating material, the insulating material has a vertical width and horizontal width the same dimensions as the attachment portion and is thinner than the pillar, and the left and right side surfaces of the insulating material are cut to form an inclined surface from the indoor side toward the face material, and a sealed edge consisting of an acute angle is formed at the indoor end.

[0010] The inclined surface is cut at an inclination angle of 5 degrees with respect to the surface material. Furthermore, when the wall insulation panel is installed on a pillar of a building, it is configured to form an intra-wall air gap that allows air to circulate between the board installed on the indoor side of the building and the insulation material. Effect of the Invention

[0011] Since the present invention has the configuration as described above in detail, it has the following effects. 1. Since an inclined surface is formed on the left and right sides of the insulation material from the inside of the room toward the facing material, the insulation material is installed with the inside of the room abutting firmly against the pillar, making it possible to ensure sufficient airtightness with the insulation material. 2. The inclination angle of the inclined surface is 5 degrees, which makes the gap between the outside of the insulation material and the pillars extremely narrow, making it possible to prevent condensation from forming in that area.

[0012] 3. The structure is designed to create an air gap between the boards on the interior side of the building and the insulation, allowing air to circulate through the air gap. This makes it possible to adjust and keep the temperature inside the building constant, and also enables ventilation within the building structure, which dries the wood and prevents corrosion and mold, making it possible to provide a house with excellent durability. BEST MODE FOR CARRYING OUT THEINVENTION

[0013] DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The wall insulation panel according to the present invention will now be described in detail with reference to the embodiments shown in the drawings. Fig. 1 is a bottom cross-sectional view of a wall insulation panel according to the present invention, Fig. 2 is a side cross-sectional view of the wall insulation panel showing the installation procedure, Fig. 3 is a diagram showing an embodiment of the wall insulation panel, Fig. 4 is a cross-sectional view of the insulation material, and Fig. 5 is a diagram showing a structure for ventilation inside the building structure.

[0014] The wall insulation panel 1 of the present invention, as shown in Figures 1 and 2, consists of a facing material 100 and an insulating material 200, and is fixed between the pillars 10 of a building to provide insulating effects, making it possible to easily insert the insulating material between the pillars while ensuring sufficient airtightness when inserting the insulating material between the walls, and is a wall insulation panel having an air gap within the wall to provide ventilation within the structure.

[0015] The surface material 100 is a plate-like member that constitutes the wall surface of a building, and is a thin cube having a square shape when viewed from the front as shown in Figures 1 and 2. In this embodiment, the surface material 100 is made of plywood or plywood, but is not limited to this configuration.

[0016] The heat insulating material 200 is a member having heat insulating properties that is placed inside the roof of a building, and is a vertically elongated member having a cubic shape as shown in Figures 1 and 2. In this embodiment, the heat insulating material 200 is made of polystyrene foam, but is not limited to this, and any member having heat insulating properties can be appropriately selected and used.

[0017] The wall insulation panel 1 according to the present invention is configured to be inserted and fixed between the pillars 10 of a building as shown in Figures 1 and 2. This configuration allows the prefabricated wall insulation panel 1 to be easily installed on-site, making it possible to construct a building with high thermal insulation effect, and also makes it possible to form an intra-wall air space 30 that provides ventilation within the building structure sealed by the insulation material 200, as described later.

[0018] In this embodiment, the facing material 100 is configured to include a fixing portion 110 and an attachment portion 120, as shown in Figures 1 and 2. The fixing portion 110 is an area formed with a constant width along each side on the indoor side surface of the facing material 100, and by attaching this portion to a pillar 10 of a building, the wall insulation panel 1 can be easily fixed and installed to the building via the pillar 10.

[0019] The attachment portion 120 is an area for attaching and fixing the insulating material 200 to the facing material 100, and is configured to be formed on the indoor side of the facing material 100, inside the fixing portion 110, as shown in Figures 1 and 2. The attachment portion 120 is configured to have the same shape as the outdoor side surface of the insulating material 200.

[0020] In this embodiment, as shown in Figures 1 and 2, the insulation material 200 is a member having the same vertical and horizontal dimensions as the attachment part 120 and a thickness thinner than the pillar 10. That is, the insulation material 200 is attached to the attachment part 120, which has the same shape as the outdoor side surface of the insulation material 200. In addition, since it is thinner than the pillar 10, a space is formed between the board 20 provided on the indoor side and the insulation material 200, and the pillar 10 and the insulation material 200 are in close contact with each other, so that this space becomes the intra-wall air space 30 that does not leak air.

[0021] With this configuration, the insulation material 200 can be attached and fixed to the facing material 100 in advance at a factory or the like, and then transported to the construction site and easily assembled on-site, which makes it possible to simplify the work and shorten the construction period when constructing a building with an air gap within the wall that serves to ventilate the structure.

[0022] In this embodiment, as shown in Fig. 3, a receiving material 12 can be provided on the indoor side of the heat insulating material 200, and screws 14 can be used to screw and fix the heat insulating material 200 from the facing material 100 side so as to sandwich the heat insulating material 200. With this configuration, the facing material 100 and the heat insulating material 200 can be securely fixed without being attached, and the screw fixing can be easily separated during dismantling, facilitating separation processing.

[0023] In this embodiment, as shown in Figures 1 and 4, the left and right side surfaces 210 of the thermal insulation material 200 are configured to have inclined surfaces 220 cut from the indoor side toward the facing material 100. In other words, the left and right side surfaces 210 of the thermal insulation material 200, which are surfaces that press and abut against the pillars 10, are configured to have an inclination angle so that they widen left and right from the indoor side toward the indoor side.

[0024] In this embodiment, as shown in Fig. 1 and Fig. 4, a sealing edge 230 formed at an acute angle is formed at the indoor end of the left and right side surfaces 210. The sealing edge 230 is a portion that is crushed when the heat insulating material 200 is pressed against the column 10, and by being crushed, it comes into close contact with the column 10, increasing the airtightness of the building and forming an air gap 30 within the wall that does not leak air.

[0025] In this embodiment, the sealing edge 230 is configured to be at an acute angle with respect to the pillars, as shown in Figures 1 and 4. If the sealing edge 230 were cut in the opposite direction to the inclined surface 220 or rounded, it would be easier to fit the insulation material 200 between the pillars 10, but since the sealing edge 230 would not be crushed, airtightness would be lacking, which would cause condensation. By making the sealing edge 230 at an acute angle, the insulation material 200 is fitted between the pillars 10 while abutting against and crushing the pillars 10, making it possible to ensure high airtightness.

[0026] Next, an outline of construction of the wall insulation panel 1 according to the present invention will be described. In this embodiment, the wall insulation panel 1 with the insulation material 200 attached to the facing material 100 is pushed between the pillars 10 from the outside of the room, and the fixing part 110 of the facing material 100 is nailed to the pillars 10 to fix it. At this time, if the insulation material 200 is sized to match the width between the pillars 10 without providing an inclination angle, if the pillars 10 are twisted, the insulation material 200 will not fit between the pillars 10, and the wall insulation panel 1 will not be able to be installed. Also, if the width of the insulation material 200 is made narrower than the width between the pillars 10 to allow some space, gaps will be created and airtightness will not be ensured.

[0027] In order to make the cross section of the insulation material 200 trapezoidal, an inclination angle is provided on the surface (left and right side surfaces 210) of the insulation material 200 that comes into contact with the pillar 10 to form an inclined surface 220, and the narrower of the parallel opposite sides of the trapezoid cross section faces the panel 100 side, and the wider side faces the room side. With this configuration, when the insulation material 200 is pressed between the pillars 10, the insulation material 200 has elasticity, so that the tip (sealed edge 230) of the wider side (room side) is fitted in a crushed state, and no gap is formed between the pillar 10 and the insulation material 200, making it possible to ensure airtightness.

[0028] Conversely, if the insulation material 200 is configured so that the wider of the parallel opposite sides of the trapezoidal cross section is on the panel 100 side and the narrower side is on the indoor side, the insulation material 200 will initially fit easily between the pillars 10, but the wide side that abuts the panel 10 will be crushed by the pillar, and the insulation material 200 will become sandwiched between the panel 100 and the pillar 10, creating a gap between the panel 100 and the pillar 10, making it impossible to ensure airtightness.

[0029] In buildings, if there is a gap between the insulation material and wood, condensation occurs, causing the wood to rot. By using the wall insulation panel 1 according to the present invention, it is possible to easily perform airtight construction, and it is possible to provide a wall insulation panel with an air gap within the wall, which allows the insulation material to be easily inserted between pillars while ensuring sufficient airtightness when the insulation material is inserted between the walls.

[0030] In this embodiment, the inclined surface 220 of the heat insulating material 200 is cut at an inclination angle of 5 degrees with respect to the facing material 100, as shown in Fig. 4. By forming the inclination angle at 5 degrees so as to spread from the facing material 100 side toward the room side (so that the angle formed by the facing material 100 and the left and right side surfaces 210 is 85 degrees), as shown in Fig. 1, it is possible to minimize the space formed between the facing material 100, the heat insulating material 200, and the pillars 10, and to easily insert the heat insulating material 200 between the pillars 10 while maintaining airtightness.

[0031] On the other hand, if the temperature is greater than 5 degrees, the space formed between the facing material 100, the insulating material 200, and the pillars 10 becomes too large, making condensation more likely to occur. Conversely, if the temperature is less than 5 degrees, it is possible to ensure airtightness, but it becomes difficult to insert the insulating material 200 between the pillars 10, and there is a risk that the insulating material 200 will be damaged during work. With the above configuration, it is possible to provide a wall insulation panel that optimizes the balance between ensuring airtightness and ease of installation of the wall insulation panel, and that allows the insulating material to be easily inserted between pillars while ensuring sufficient airtightness when inserting the insulating material between walls.

[0032] The wall insulation panel 1 according to the present invention can be configured to include an in-wall air gap 30, as shown in Figures 1 and 5. The in-wall air gap 30 is a flow path for air circulation, which creates a thin space inside the wall of a building and circulates air from under the floor inside the space, making it possible to maintain the indoor temperature cool in summer and warm in winter, and also enabling ventilation inside the building structure, drying wood to prevent corrosion and mold, and providing a house with excellent durability and high asset value.

[0033] As shown in Figures 1 and 2, in this embodiment, when the wall insulation panel 1 is installed on the pillar 10 of the building, the wall air gap 30 is formed between the board 20 installed on the indoor side of the building and the insulation material 200, and by circulating air in this space, it is possible to adjust the temperature in the room and ventilate the inside of the building. With this configuration, it is possible to build a more comfortable and durable building with simple construction.

[0034] The concrete foundations that make up buildings contain a large amount of water, so it is said that it takes two to three years for the moisture inside a house to completely evaporate. It is common to put insulation under the floor or in the attic and then lay moisture-proof sheets over it, but this prevents the moisture from evaporating. In addition, a construction method called spray insulation, in which insulation is placed tightly inside walls, also prevents moisture from evaporating, which causes condensation.

[0035] The wall insulation panel of the present invention is designed to create an air gap within the wall, allowing air to flow inside the wall. This ensures airtightness of the insulation material, while creating gaps under the floor, inside the wall, and above the ceiling that allow air to move naturally, allowing ventilation within the building frame, drying wood, and creating a house with excellent durability that is free from termite damage, wood rot, and mold growth.

[0036] Next, we will outline the construction of an air gap in the wall for ventilation inside the building structure. The foundation of the building will be a double-sided foundation insulation that lowers the insulation material on the outside to the freezing depth.

[0037] As shown in Figure 5, 30 mm slits 17 are made in the floorboards 16 on the perimeter of the building. The dimensions of the pillars 10 are set to 120 mm, the dimensions of the foundations (beams) 18 to 105 mm, and the widths of the foundations 18 and beams are made smaller than the dimensions of the pillars 10, leaving a 15 mm gap, aligning the outsides, and creating gaps to allow air to flow inside the wall. Then, seamless 70 mm insulation material 200 is placed between the pillars 10 with airtight construction, creating a 50 mm gap.

[0038] When a 15mm base plate 19 is attached to the pillars 10 and the boards are laid, a 65mm air gap 30 is formed within the wall, and a 30mm gap is formed in the floor. This allows air to circulate from under the floor into the wall, enabling ventilation within the structure, and by drying the wood after construction, it is possible to build a house with excellent durability that is free from termite damage, wood rot, and mold growth.
