Description

Detailed Description of the Invention "Field of Industrial Application" The present invention relates to a new heat insulating board used as a siding base material for external walls of buildings, a base material for roofs, a base material for floors, etc. This article relates to a wooden house with an air flow system that utilizes the characteristics and functions of the house, as well as corner pieces for the inside and outside corners of the house.

``Prior art'' As a thermal insulation board for construction, for example,
No. 65650, a plate made of wool-based insulation materials such as high-density glass wool boards, foamed plastic boards, fiberboards, plywood, etc., with grooves perpendicular to each other formed on one side of the plate to form grooves that connect vertically and horizontally. , or a thin hole that penetrates the front and back of the plate at the intersection of the grooves is used as a backing material for roof sheathing boards or finished exterior wall materials, with the groove surface being the receiving surface. The vertically and horizontally connected grooves form a ventilation layer, allowing air to flow directly under the roof sheathing board or on the back of the exterior wall, resulting in cooling, heat retention, no melting of snow, prevention of swarming, prevention of dew condensation, moisture dissipation, etc. It has been proposed that it be used for

In addition, as a commercially available product having a similar function, as shown in FIG. 8a, cut grooves 2a and 2b are formed on one side of the expanded polystyrene board 1 to be perpendicular to each other, and grooves 2a and 2b are provided at the intersections of the grooves for reinforcement and for four-way ventilation. A rotary 3 is installed, or a finished exterior wall material 4 whose main components are volcanic lapilli, pulverized coal combustion ash, and inorganic materials such as glass fiber is integrally laminated on the cut surface of the board 1 as shown in Figure b. A heat insulation board 5 is provided.

The use of these materials as exterior wall materials is based on the above-mentioned Japanese patent publication
It is the same as No. 55-65650, and the rectangular measurement and attachment procedure for the board 5 as an exterior wall material on which the finished exterior wall material 4 is laminated are as shown in Figures c and d.

In the figure, 6 to 8 are beams, columns, and braces, 9 is foundation, and 10
11 and 12 indicate the eaves, and 11 and 12 indicate the draining iron plate and the draining base, respectively.

In addition, the inside and outside corners indicated by the encircling lines f and g in the overall view of the house shown in Figure e are constructed as shown in Figures f and g, and the inside and outside corners are One of the boards 5 abuts against the mounting crosspiece 13 via the plywood 14 as a butt seat.
The side edge of the other board 5 is butted against the finished surface 4 of the board 5, and in this part, the ventilation passages of the orthogonal grooves 2a and 2b are formed between the pillars 7, and are usually filled with an inner heat insulating material such as glass wool. It communicates with space 15.

In addition, if the protruding corner is configured like the incoming corner described above, the fragile side edge of the foamed polystyrene board 1 will be exposed to the outside, so the foamed polystyrene board 1 has cut grooves 2a and 2b.
Insulation board 1 laminated with finished external wall material 4 without applying
A corner piece 17 is specially manufactured where the end pieces of the board 5 are edged and perpendicularly butted together, and the side edge of the board 5 is connected to this. Due to the absence of , no ventilation layer is formed.

As mentioned above, Japanese Patent Application Laid-Open No. 60-226932, which was proposed by the present applicant, is a device that aims at ventilation within the outer wall.

The gist of this is that continuous narrow-gap ventilation passages are formed in the middle and outer halves of the external insulation material directly under the exterior wall materials, leading to all directions in the vertical and horizontal directions, and the upper and lower ends of the ventilation passages are connected to the entire attic in all directions. An enclosed attic space with a parapet with a ventilation hole around the upper edge, connected to the outside air so that the outer half of the external insulation material is covered with a strong upward draft of outside air, and a mixture of warm and cold air with a temperature difference. The air curtain uses only outside air to completely eliminate condensation, dramatically reduce thermal conductivity, improve soundproofing, and improve the durability of wood. The flow effect prevents direct exposure to external cold air.

That is, in FIGS. 9a and 9b, reference numeral 18 denotes an inner heat insulating material made of, for example, glass wool wrapped in polyethylene film, etc., which is also placed on the ceiling and floor. 19 is an attic space, and in order to promote air movement in the attic space 19 on all sides around it,
It's deliberately set too high. In other words, parapet 26
A ventilation hole 20 is provided around the outer circumference of the upper end.

Therefore, the attic space 19 has a ventilation hole 20 with a large opening area located at a high distance and not on the same level.
As a result, it is under a rapid flow without congestion and is not stimulated by external cold air.

Reference numeral 21 denotes a beam, and reference numeral 22 denotes an external heat-insulating external wall material made by laminating an external wall material 22a mainly composed of inorganic materials such as volcanic lapilli, pulverized coal combustion ash, and glass fiber, and an external heat-insulating material 22b made of expanded polystyrene. As shown in the cutaway view of the external heat insulating outer wall material 22 in Figure d, continuous gaps are carved in the outer half of the external heat insulating material 22b, forming air passages 23 communicating in all directions.

The upper end of the ventilation passage 23 is connected to the attic space 19, and the lower end is as shown in detail in the enlarged view of Figure b.
A group of ventilation holes installed in advance on the floor 24 are connected to the outside air by placing them on a perforated receiving aluminum angle 25. Therefore, as shown in Figure c, the air in the attic space 19 escapes due to the suction action from the attic ventilation opening 20 due to the flow of outside air, and at the same time, the outside air enters through the lower end opening of the external insulation material 22b. The outside air rises and escapes from the ventilation opening 20, forming an uncongested flow path for outside air.

The outside air flow path is formed by the external heat insulating material 22b as described above.
As a result of extending in all directions with a narrow gap in the outer half, a strong flow of outside air is formed over the entire surface, and the outer insulation material 22b is like an air curtain caused by outside air.
The outside surface will be covered and the attic space 19
Run through.

This air curtain and flow stimulate thermal conductivity (blocking cold air from entering the room from outside)
This improves the soundproofing effect, but the most important thing is that there is no condensation due to the strong flow of only outside air, which not only maintains the performance of the external insulation material 22b but also protects the pillars etc. that come into contact with it. This prevents the wood from getting damp, keeping the wood fresh and improving the durability of the building.
It is possible to eliminate condensation in the air.

The feature of this proposal is that it converts the extremely powerful flow energy of the wind into an upward flow within the outer wall, and at the same time secures an escape outlet to form a flow without any congestion.

Now, as a proposal for a wooden house with an air flow system that takes into consideration the ventilation of the roof surface, there is
In this issue, there was one in which boards with the above-mentioned ventilation layer were laid under the roof decking board, and in 1982-
By installing a non-wooden corrugated board between the roof board and the roof board in No. 149526, the use of the non-wooden corrugated board prevents condensation in the attic in the winter and build-up of heat in the attic in the summer. Some argue that roof insulation becomes unnecessary.

"Problem to be Solved by the Invention" The various heat insulating materials mentioned above or those laminated with finished external wall materials do not have structural strength due to their material nature, and they cannot be used as a screw fastening layer. It has no strength and is only used as a filling material for the voids between structural frames, and if it is screwed to the structural frame, it will not work in areas where there are many earthquakes or where there are many entrance openings. If it does not fit in, the screw-fastened portion of the insulation material may break due to the horizontal shaking, causing the board to lift or peel off.

Similarly, when used as a base for fixing screws to siding base materials for exterior walls, corrugated iron base materials for roofs, floor base materials, etc., siding materials, galvanized iron base materials do not have sufficient strength. , causing the floor etc. to float.

However, since it itself does not have the strength to serve as a base for fixing screws, as in the previously mentioned Japanese Patent Application Laid-Open No. 55-65650, if it is not directly supported on the roof surface itself, but is placed through a roof board, It has become something we have no choice but to do. In this way, requiring the intervention of something strong enough to serve as a screw fixing base requires lamination work, which is time-consuming. In addition, in the case of galvanized iron, there is no ventilation between the intervening roof board and the galvanized steel, and
Due to the high thermal conductivity of galvanized iron, condensation forms on the back side of the galvanized iron, especially in winter, and this condensation causes a decline in the performance of the roofing boards (wooden). As described above, in many cases, the ventilation layer cannot be effectively utilized for the material to be attached due to insufficient strength. In terms of ventilation directly under the roof surface, the above-mentioned Utility Model Application Publication No. 149526/1984 has a ventilation path directly under the galvanized iron, so there is no problem like the one mentioned above. A heat-reflective roofing material made of metal foil, metal paper (for example, silver paper), or other material is laid over the top surface of the roofing board, and a corrugated board is placed on top of the roofing material. Because it is a system that requires a system to be set up, there are various difficulties as detailed below. That is,
In the summer, when the sun shines on galvanized iron, it has a high thermal conductivity, so the roofing (black) underneath also has a high heat absorption rate, so the roofing is susceptible to heat and weathering. The fact is that the attic is irritated due to the high rate. As a result, the temperature in the room is rising. The same can be said in winter.
The reality is that condensation and soot leaks especially in areas like Hokkaido where there is a large difference in temperature. Also, instead of roofing, a heat reflective material is used to create a ventilation layer and a square wave structure is used, but even in the summer, since the material is made of galvanized iron, which has good thermal conductivity, When a heat reflective material is provided under the galvanized iron, the heat is transmitted through the galvanized steel and the heat from the sun on the surface is reflected by the heat reflective material, making the paint on the galvanized steel susceptible to attack by the heat. The same thing can be said in the winter, but because there are heat-reflecting materials, especially in areas with large temperature differences like Hokkaido, if there is snow on the roof, it will simply melt from above due to the heat of the sun during the day. The heat-reflecting material conducts heat from below and melts from below, causing it to freeze at night. As a result of this continuation, the ice builds up day by day, reaching the galvanized iron and the seams, irritating the seams, which are the seams, and causing the seams themselves to expand due to the freezing. Therefore, water from snow that melts during the day can cause rain leaks. Also, since there is a heat reflective material under the galvanized iron, condensation is likely to form on the back of the galvanized iron. In addition, even in winter when there is little snow, the sun shines during the day and cold waves cause the surface of the galvanized steel to freeze, and if a heat reflective material is placed under the galvanized steel, the heat from the sun will pass through the galvanized steel and be reflected. condensation forms under the galvanized iron. Furthermore, since a waterproof plate is placed in front of the open end of the corrugated plate to block the ventilation path, the fluidity in the ventilation path is poor, and ventilation performance cannot be expected to be that great, resulting in condensation due to accumulation. obtain. In addition, in the above-mentioned structure of the inside corner, the indoor temperature leaks to the outside through the finished outer wall material 4, and in the structure of the projecting corner, no ventilation layer is formed by the grooves 2a and 2b. Therefore, the moisture dissipation effect cannot be suspended as in other parts, and therefore, moisture dissipation cannot be achieved at the corner parts.

The present invention was developed in view of the above-mentioned circumstances, and provides a foamed plastic insulation board having a laminated portion that has structural strength and ventilation ability, and utilizes the insulation board for an air-cross-flow type wooden house with excellent ventilation. It also aims to provide corner pieces for the inside and outside corners of the house.

"Means for Solving the Problem" In order to achieve the above object, the insulation board of the present invention has cut grooves perpendicular to each other on one side of the plate,
A rotary weir is provided at the intersection of the kerfs, and structural plywood is integrally laminated with multiple through holes communicating with the kerfs on the kerf surface of the foamed plastic board.

The air flow type wooden house of the present invention uses the above-mentioned insulation board as the base material for the siding on the exterior wall surface using the structural plywood as the base material, and has ventilation passages leading to all directions arranged vertically and horizontally in the middle and outer halves of the external insulation material. The upper and lower ends of the ventilation passage are connected to the outside air and to an attic space having a parapet that surrounds the entire attic on all sides and has a ventilation opening around the outer periphery of the upper end.

The above-mentioned insulation board may be used as a base material for the roof surface of the above-mentioned air flow type wooden house, with the structural plywood used as the base material. Alternatively, the above heat insulation board may be used as a base material for the floor surface using structural plywood as the base material. Furthermore, the above-mentioned heat insulation board may be used as a base material for a roof surface and a floor surface using structural plywood as the base material.

The above measures may be applied to wooden houses with flat roofs that do not shed snow and have eaves that surround the entire attic on all sides and have ventilation holes around the top.

The in-corner and out-corner corner pieces of the present invention are made by abutting orthogonal edges of the above-mentioned heat insulation board end pieces while ensuring orthogonal cut grooves in the boards.

"Function" The insulating board of the present invention, which has structural strength due to the use of structural plywood, can withstand use as a structural material, and its breathability allows it to dissipate moisture on the back side of the finishing material when used as a base for various finishing materials. Do this.

Furthermore, if a wooden house using the air circulation method is constructed by using the heat insulation board of the present invention on the outer wall surface, the house will not only be able to dissipate moisture in the heat insulating material, but will also be able to accommodate the above-mentioned uses.

Furthermore, by connecting air passages to the roof and floor surfaces of the strong upward air flow formed on the outer wall surface using the insulation board of the present invention, ventilation can be achieved not only on the outer wall but also on the roof and floor surfaces. You can receive profits from this. In addition, the inside and outside corner pieces provide proper ventilation to the corners as well as other parts.

"Example" Examples will be described with reference to the drawings.

Fig. 1 is a cutaway overhead view of the heat insulating board of the present invention, and Figs. 2 a and 2 b are explanatory diagrams of the use of the inventive heat insulating board as a siding base material for an external wall surface, corresponding to the previously described Figs. 9 a and b. , the same components are given the same reference numerals.

Fig. 5 is a longitudinal cross-sectional view when the present invention is used, and Fig. 5 is an explanatory view of air flow when the inventive insulation board is used on the outer wall surface and the floor surface of the roof. An explanatory diagram of air flow in a snow-free flat roof that has an eave that surrounds the entire attic on all sides and has ventilation holes around the upper edge. FIG. 3 is a cross-sectional view of the corner piece.

In FIG. 1, on one side of the plate of a foamed plastic board 27 such as foamed polystyrene, cut grooves 28a and 28b are formed perpendicularly to each other, similar to the board 1 described above, and the cut grooves 28a,
A rotary weir 29 for reinforcement and four-way ventilation is provided at the intersection 28b, and a structural plywood 30 is integrally laminated on the groove surface on which the ventilation layer is formed.

The plywood 30 has the cut grooves 28a,
A plurality of through holes 31, . . . communicating with 28b are provided.

Thus, the heat insulating board 32 of the present invention constructed as described above is given structural strength by the structural plywood 30 and serves as a structural board, and since it is made of wood, it can also serve as a base for fixing screws.

It goes without saying that the plywood 30 is suitable as a base for pasting, laminating, and screwing various finishing materials. Furthermore, since the plywood 30 is provided with through holes 31, .

Therefore, the heat insulating board 32 of the present invention can be used as a structural board in an opening without bracing, and will not float due to horizontal shaking or the like.

In addition, a breathable siding base surface (plywood 30) is provided. In addition, the kerf grooves 28a, 28
Regarding the formation of the ventilation layer by b, use the board 2 described above.
It is the same as 2. Such insulation board 32
As shown in the figure, when the plywood 30 is used as the base surface of the external wall siding in place of the heat insulation board 22 in FIG. 9, structural strength is added to the frame as described above.
An air flow type wooden house is provided which has a new function and effect of imparting breathability to the exterior wall siding 33. In addition, numeral 34 in the figure indicates a ventilation layer in the board 32.

The present invention board 3 is based on the assumption that the above-mentioned wooden house has a strong air curtain on the outer wall.
By using 2 in other parts and connecting the ventilation layer, a house with excellent breathability can be provided.

That is, as shown in FIG.
can be used as a corrugated iron base material for roofs, and rafters 3
5. Lay the board 32 of the present invention as a field board on top with the plywood 30 facing upward, and attach the plywood 30 to the hangers 36,
...If the long galvanized iron plates 37,... are constructed with the sills 38,... while using the fixed base, the plywood 30 will be used in place of the roofing board, so the area directly under the galvanized iron plates 37 will be in communication with the ventilation layer 34. , and since there is no heat reflecting material,
The inconvenience in No. 62-149526 is resolved.

In addition, the ventilation layer 34 formed on the back of the roof surface mentioned above
As mentioned above, is connected to the ventilation layer in the outer wall portion in FIG. 2, and the details will be described later.

As mentioned above, the details of the effect when the board 32 of the present invention is used as the corrugated iron base for the roof surface are as follows. In other words, since there is a ventilation hole under the galvanized iron, in summer, hot air from the roof passes through the ventilation hole and into the ventilation path of the board 27, which consists of four ventilation paths, and is always open. In the winter, the cold air passes through the roof, preventing snow from melting on the roof and preventing roof leaks. In addition, since there are ventilation holes under the galvanized iron, the thermal conductivity of galvanized iron makes it easier for cold air to flow through the ventilation holes, which not only eliminates condensation on the back of the galvanized iron, but also creates ventilation channels on all sides. ing. Because it flows into a constantly open air stream, it has the effect of reducing the temperature difference between the front and back of the galvanized iron.
In addition, since it is integrally molded, it reduces work costs, and as a roofing board material, it is finished flat, which improves the tension of the galvanized iron.

Next, the board 32 of the present invention can also be used as a base material for a floor surface, as shown in FIG.
is laid as the base surface of a floor finishing material 39 such as jutan. In addition, the laid board 32 penetrates through the column/beam groove surface as shown in the figure, and further penetrates the back side of the present invention board 32 pasted as an exterior wall base material.
The ventilation layers 34 are communicated with each other.

Therefore, even with the drawing action of the strong upward air flow on the outer wall, air flow is brought into the board 32 laid as a base material for the floor surface. As a result, an air curtain is formed behind the floor, producing the following effects. That is, the floor finishing material 39 is inserted through the through hole 31 of the plywood 30.
The back side of the floor is ventilated, eliminating dew condensation that could not be prevented in the past, improving the durability of the wood that makes up the flooring, controlling the growth of mites and mold, and providing a suitable environment for all flooring materials.

As for the floor, as mentioned above, the board 32 is connected to the board 32 on the outer wall and passes through it without interruption at the column/beam groove surface, so the effect of blocking the cold air 40 that enters from the bottom of the floor is low. Extremely excellent. In the figure, 41 indicates a ventilation hole installed on the underside of the eaves, and for other configurations that are the same as in Figure 2,
The same symbols are attached.

The above-mentioned use as a roof underlayment material and use as a floor underlayment material may be performed at the same time.

Figure 5 shows a parapet 2 that surrounds the entire attic on all sides and has a ventilation opening 20 around the upper end.
6 shows the ventilation when the board 32 of the present invention is used for the exterior walls, roof, and flooring of a house having a housing with a housing having a housing equipped with a housing having a housing 6.

In this case, the roof surface starts from the upper end of the parapet 26,
The water on the roof is drained through the drain 42 into the manhole 43. The side ends of the ventilation layer 34 of the board 32 laid as a roof base material are open to the attic space 19, and as in the case of the floor described above, it is drawn into the air curtain flow of the outer wall and flows. The air curtain flow on the outer wall in the case of the board 32 laid on the roof surface of a snowless type flat roof that surrounds the entire attic on all sides and has an eave 44 with a ventilation hole around the upper edge. The manner of communication between them is shown in FIGS. 6a and 6b.

In the case of figure a, the board 32 is spread over the entire surface, and the side openings of the ventilation layer 34 are directly exposed to the outside air. However, a waterproof plate 45 is provided to protect against rain.

Since the ventilation hole 20 is located directly below the above-mentioned opening, it is drawn into the air curtain flow of the outer wall dissipating from this hole, causing a flow inside the board 32.

In the case of figure b, the board 32 is interrupted on the pillar 46, and the side end opening of the ventilation layer 34 is exposed to the attic space 19. Therefore, when the air curtain flow on the outer wall draws in the air from the attic space 19, it is drawn in, causing a flow inside the board 32.

Although not shown, as in Figure 5, the eaves 44
The present invention board 32 is installed on the floor even if the house has a
There are also cases where it is used.

Inner corner and outer corner corner pieces 47, 4 of the present invention
8 is a heat insulating board 3 as shown in FIG. 7a and b.
The two end pieces 32', 32' are respectively edged and orthogonally butted together with the cut grooves 28a, 28b secured.

As a result, the heat insulating layer with breathability, which was formed on the flat area used as the base material for the exterior wall, is formed continuously without interruption even at the corners, and as a result, the inconvenient phenomenon described above occurs. As a result, a suitable air curtain can be formed all around the house.

"Effects of the Invention" According to the invention described in claim 1, it is possible to supplement the structural strength of a heat insulating board capable of forming a ventilation layer, and to impart breathing ability to the finishing material attached.

In the inventions described in claims 2 to 9, a breathing function is imparted to the wooden house to perform dew condensation and moisture dissipation, thereby significantly increasing the durability of the house.

According to the tenth aspect of the invention, the durability of the house is increased by ensuring the same breathing function as the flat part of the outer wall even at the inside corner and the outside corner.
