Description

  The present invention relates to a heat insulating panel that inhibits or suppresses heat transfer, and in particular, heat transfer between a cabin back formed on a ceiling and a room by being installed on an eaves girder constituting a house. The present invention relates to an upper insulation panel for preventing or suppressing.

  Until now, heat insulation has been frequently used inside the walls of houses and the like. And the material of this heat insulating material mainly occupied glass wool. However, recently, in order to promote energy saving, airtightness and heat insulation have been promoted, and heat insulation made of urethane foam has come to be used, and vacuum insulation is embedded inside. Has been proposed (see Patent Document 1).

If such a heat insulation panel is used, not only energy saving can be realized by promoting high airtightness and high heat insulation, but also weight reduction and workability are improved. And if such a heat insulation panel is installed on a girder or beam, it becomes possible to prevent or suppress the movement of heat between the back of the cabin formed on the ceiling and the room, making it even more highly airtight and highly insulated. Can be promoted.
However, when constructing such a heat insulation panel on the eaves girder, the heat insulation panel to be constructed in a part separated from the eaves girder may be a flat shape formed in a square shape and spread like a tile. However, the thermal insulation panel closest to the eaves girder often interferes with a rafter whose midway is supported by the eaves girder. In particular, the greater the thickness of the heat insulation panel, the more the part closer to the eaves can not be constructed without leaving a gap.
Therefore, in the past, in order to avoid interference with the rafters, the actual situation is that the heat insulation panel is scraped into an appropriate shape at a construction site such as a house and then installed on the eaves girder.
Japanese Patent Laid-Open No. 10-211986

  However, the work of scraping the heat insulation panel at a construction site such as a house is extremely complicated so that an inclined surface having an inclination angle that does not interfere with the rafters is formed, which not only lengthens the construction period but also generates waste materials at the construction site. It will be. Furthermore, when the vacuum heat insulating material is embedded inside like the heat insulation panel disclosed in Patent Document 1, the vacuum heat insulating material is damaged (broken bag) during the work of scraping the heat insulating panel. There is a high risk of significantly reducing the insulation effect.

  Therefore, the present invention has been proposed to solve the problems of the conventional heat insulation panel described above, and the work of scraping off at the construction site becomes unnecessary, reducing the generation rate of waste materials and shortening the construction period. An object of the present invention is to provide a new upper thermal insulation panel that contributes and suppresses the risk of scratching the vacuum thermal insulation material embedded therein.

In order to achieve the above-described object, the present invention (invention according to claim 1) is a girder heat insulation panel constructed to be supported by an eaves girder, and has urethane resin as a main material, and has an inside.

The vacuum heat insulating panel is formed in a plate shape, and is integrally formed by a nest in which a nesting side inclined surface corresponding to the number and inclination angle of the inclined surface is formed. The upper and lower materials are embedded in the thickness direction, and a vacuum heat insulating material protective plate is disposed on the lower surface. The vacuum heat insulating material protective plate is integrated with the urethane resin. Is.

Incidentally, the digit on the insulating panel is required to be made of a urethane resin as the main material, the urethane resin has both the properties of such hard-soft, is also desirable thermal insulation properties are high material. Moreover, in this 1st invention, although it is required that the vacuum heat insulating material is embed | buried inside, the number of this vacuum heat insulating material is plural, like 4th invention (invention of Claim 4). It is not limited to a certain thing, A single may be sufficient. Moreover, the upper heat insulation panel according to the present invention is formed with one or a plurality of inclined surfaces, and this (or these) inclined surfaces are arranged in a mold when the upper heat insulating panel is manufactured. It needs to be formed by nesting. This nesting is formed with an inclined surface to be formed on the girder thermal insulation panel, that is, an inclined surface having an inclination angle capable of avoiding interference with a rafter supported by an eaves girder where the upper thermal insulation panel is installed. It is what. In addition, the said vacuum heat insulating material protection board should just be a plate-shaped body which can protect the vacuum heat insulating material embed | buried under the inside of a urethane resin at least, Specifically, it is using a plywood, a hard resin board, etc. it can.

  According to a second invention (invention of claim 2), in the first invention, two inclined surfaces are formed, and the nesting includes two corresponding to these inclined surfaces. A nesting side inclined surface is formed.

  DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, an upper heat insulation panel according to the best mode for carrying out the present invention, a mold for manufacturing the same and a manufacturing process will be described in detail with reference to the drawings. First, the first to third upper thermal insulation panels will be described.

  As shown in FIG. 1 or FIG. 2, the first upper thermal insulation panel 1 according to the embodiment of the present invention includes a panel main body 2 made of urethane resin (hard urethane foam), two vacuum thermal insulation materials 4, and the like. 5 and the plate-like heat insulating material 6 are integrally formed. The plate-like heat insulating material 6 having this configuration is made of beaded polyethylene foam (so-called EPS), and this plate-like heat insulating material 6 constitutes the vacuum heat insulating material protective plate of the fourth invention. Then, on the upper surface of the plate-like heat insulating material 6, two vacuum heat insulating materials 4 and 5 are laminated so as to form blanks on four sides of the plate-like heat insulating material 6. These vacuum heat insulating materials 4 and 5 have the same configuration, and glass wool (not shown) is sealed inside a bag body having an aluminum foil layer, and the inside of the bag body is evacuated and sealed. . And the panel main body 2 is integrally shape | molded so that the said plate-shaped heat insulating material 6 and the two vacuum heat insulating materials 4 and 5 may be embed | buried. The panel main body 2 includes a rectangular parallelepiped plate-like portion 2a and an inclined portion 2b having an inclined surface 2c in which a tip portion of an upper surface formed integrally with one side surface of the plate-like portion 2a is inclined downward. In addition, the inclined surface 2c is formed at substantially the same angle as an inclination angle (see FIG. 4) formed by an upper surface of an eaves girder 12 described later of the roof to be constructed and a lower surface of the rafter 11. In addition, in this FIG. 1 or FIG. 2, the state which removed the nonwoven fabric 63 used by the manufacturing process mentioned later from the upper surface side of the 1st digit heat insulation panel 1 is illustrated.

  The first girder thermal insulation panel 1 configured as described above is used for a building such as a house where the roof surface is inclined, and as shown in FIGS. 3 and 4, a rafter that supports the lower surface of the roof (not shown) from below. 11 and the eaves girder 12 supporting the lower half of the rafter 11, and on the wooden structural plywood 10, in particular, the lower surface of the rafter 11 and the eaves girder 12 It is constructed in a narrow area near the top surface. Among these, the rafter 11 is located on the lower surface of the roof, has a length extending from the upper end to the lower end of the lower surface of the roof, and is installed along the lower surface of the roof. Moreover, the eaves girder 12 is a kind of girder which is a horizontal member generally installed in parallel in the length direction of the building, and is particularly located at the most eaves end. Further, the eaves girder 12 supports the rafter 11 in a midway portion near the lower end of the rafter 11, and is installed in a direction orthogonal to the rafter 11. The structural plywood 10 is a wooden plywood placed on the top surfaces of the eaves girder 12 and the beam 15, and has the same size and shape as the bottom surface of the first girder thermal insulation panel 1, In other words, it is used as a pedestal for constructing the first upper thermal insulation panel 1. Such a structure in which the lower surface of the inclined roof of the building is supported by the rafters 11 and the eaves girder 12 is a structure often used in wooden houses. Also, the structure of the roof of this wooden house depends on the number of roof surfaces and the direction of the inclination, for example, the two roof surfaces are inclined in two directions with a straight ridge located at the top of the roof as a boundary. “Roof”, “Side-flow roof” where the surface of four roofs inclines in four directions with the ridge at the top of the roof as a boundary, “Single roof” in which one roof surface inclines in one direction, roof It is classified as “square roof” in which the surfaces of four roofs incline in four directions from the top of the. In addition, the classification of the structure of the roof of the wooden house is not limited to these, and there is also a combination of two or more buildings with the same or different types of the above-mentioned roof structure in different directions. .

The first girder thermal insulation panel 1 is formed under the ceiling and the shed 13 which is a space formed on the ceiling of the building having a roof structure using the rafters 11 and the eaves girder 12. It is a heat insulation panel constructed to prevent or suppress the movement of heat between the room 14 as a space, and in particular, via the structural plywood 10 on the upper surfaces of the eaves girder 12 and the beam 15 closest to the eaves It is used for the heat insulation panel to construct (refer FIG. 3). And as shown in FIG. 4, the said 1st digit heat insulation panel 1 is formed by forming the inclined surface 2c of the inclination angle 2b of the said panel main body 2 in the inclined part 2b of the said panel main body 2 substantially the same angle. The bottom surface of the rafter 11 interferes with the first girder thermal insulation panel 1 and a space is not formed at the tip of the first girder thermal insulation panel 1 on the rafter 11 side, and the thermal insulation effect is reduced. can do. When the first girder thermal insulation panel 1 is constructed, the first girder thermal insulation panel 1 is placed on the upper surfaces of the eaves girder 12 and the beam 15, as shown in FIGS. It is constructed on the structural plywood 10 made.
By the way, on the eaves girder 12, as shown in FIG.3 and FIG.4, since the rafter 11 is supported at an acute angle, when constructing the conventional heat insulation panel, especially in order to improve heat insulation, When constructing a thick conventional insulation panel, the end of the insulation panel interferes with the rafter 11, and a space is formed at the tip of the insulation panel on the rafter 11 side. It was necessary to scrape the portion corresponding to the inclination angle of the rafters 11. However, when constructing the first upper thermal insulation panel 1 according to the embodiment of the present invention, since the inclined surface 2c is formed on the panel main body 2, such work is unnecessary. FIG. 4 shows the mutual inclination angle and positional relationship between the eaves girder 12 and the beam 15, the rafter 11, and the first girder thermal insulation panel 1. In particular, in FIG. The state where the 1st girder heat insulation panel 1 in which the angle of the inclined surface 2c of the main body 2 corresponds with the angle formed by the upper surface of the eaves girder 12 and the beam 15 and the lower surface of the rafter 11 is shown. However, the angle formed by the upper surfaces of the eaves girder 12 and the beam 15 and the lower surface of the rafter 11 does not necessarily match the angle formed by the inclined surface 2c of the first girder thermal insulation panel 1. For example, if the tip of the girder insulation panel 1 (the left end shown in FIG. 4) is located near the corner of the inner corner formed by the upper surfaces of the eaves girder 12 and the beam 15 and the lower surface of the rafter 11, for example, the first The angle formed by the inclined surface 2c of the upper thermal insulation panel 1 may be smaller than the inclination angle formed by the eaves beam 12, the beam 15, and the rafter 11. Further, even if the angle of the inclined surface 2c of the first girder thermal insulation panel 1 completely coincides with the angle formed by the upper surfaces of the eaves girder 12 and the beam 15 and the lower surface of the rafter 11, the first It is not necessary to construct the upper thermal insulation panel 1 so that the inclined surface 2 c is in close contact with the lower surface of the rafter 11. That is, as described above, the purpose of constructing the first upper thermal insulation panel 1 is to prevent or suppress the movement of heat between the cabin 13 and the room 14, while sufficiently fulfilling this purpose. If the first upper thermal insulation panel 1 can be constructed, it is not always necessary to match the inclination angle of the inclined surface 2c of the first upper thermal insulation panel 1 or to adhere the inclined surface 2c. Moreover, it is good also as what prepares in advance the building in which the shape of various roofs in which several types of 1st top heat insulation panels in which the inclination angle of the inclined surface 2c of the panel main body 2 differs differs in the shape of various roofs. As shown in FIG. 3, on the side of the first upper thermal insulation panel 1, a first upper thermal insulation panel 18 and a structural plywood 19 having the same configuration as the first upper thermal insulation panel 1 are provided. Is the lower surface of the entire roof and is adjacent to the eaves girder 12.

  Next, the second upper thermal insulation panel 21 according to the embodiment of the present invention will be described. The second upper thermal insulation panel 21 has the same cross-sectional configuration as the first upper thermal insulation panel 1 and will not be described in detail. As shown in FIG. 5, the second upper thermal insulation panel 21 is integrally formed from a panel main body 22 made of urethane resin, two vacuum insulation materials (not shown), and a plate-like insulation material (not shown). ing. That is, the second upper thermal insulation panel 21 includes a plate-like heat insulating material (not shown) and two vacuum heat insulating materials (not shown) stacked on the upper surface of the plate-like heat insulating material (not shown) embedded in the panel body 22. However, the outer shape of the panel body 22 is different from that of the first upper thermal insulation panel 1 shown in FIG. As shown in FIG. 5, the panel main body 22 of the second digit thermal insulation panel 21 includes a plate-like portion 22a and an inclined portion 22b integrally formed at one corner of the plate-like portion 22a. Are formed in a quadrangular shape, and two inclined surfaces of a first inclined surface 22c and a second inclined surface 22d are formed on the inclined portion 22b. And these 1st inclined surface 22c and 2nd inclined surface 22d make the valley line 22e which rises in the diagonal direction of the panel main body 22 from the bottom face corner | angular part of the inclined part 22b into a common valley bottom in FIG. The first inclined surface 22c rises toward the upper surface on the left side, and the inclined surface that rises toward the upper surface on the right side is formed on the second inclined surface 22d. Of these, the inclination angle of the first inclined surface 22c is substantially the same as the inclination angle formed between the upper surface of the eaves girder 33 and the beam (not shown) of the roof to be constructed and the lower surface of the rafter 31. At the same time, the inclination angle of the second inclined surface 22d is formed to be approximately the same as the inclination angle formed by the eaves beam 34 and the upper surface of the beam (not shown) and the lower surface of the rafter 32, which will be described later.

  The construction application of the second upper thermal insulation panel 21 is also used for a building such as a house where the roof surface is inclined in the same manner as the first upper thermal insulation panel 1. The upper thermal insulation panel 21 has a structure in which the two roofs of one roof surface and the other roof surface, which are perpendicular to each other at a valley portion at a lower side, are close to the V-shaped valley bottom. It is below the formed trough line, and is used when constructing a corner where the eaves girder 33 and eaves girder 34 which will be described later intersect, and when constructing a so-called corner of the corner (see FIG. 6). ). In addition, as a corner | angular part of such a corner, for example, it is a case where two buildings having different length directions are combined and connected in an L shape, and the surface of the roof is inclined in different directions There is a corner of the entering corner where the abuts.

  And, as shown in FIG. 6, the roof in the vicinity of the corner of the corner where the two roof surfaces, the surface of one roof and the surface of the other roof (both not shown) contact each other, A rafter 31 that supports the lower surface of one roof from below, a rafter 32 that supports the lower surface of the other roof from below, and an eaves girder 33 and 34 that respectively support the lower ends of the rafters 31 and 32; It is comprised with the valley | tani 35 located below the valley line of the V-shaped valley bottom formed when the surface of one and the other two roofs contact | abut. The cross section of the valley 35 has a deformed pentagonal shape. The rafter 31 supports the lower surface of one roof and the lower surface of the other roof on the left and right side surfaces of the valley 35 shown in FIG. , 32 is fixed at the lower end. For this reason, when the above-mentioned conventional girder thermal insulation panel is used as the girder thermal insulation panel constructed in the portion closest to the eaves girder 33, 34 at the corner of the entrance corner, the tip portion has an inclined surface. Since it is not formed but is a right-angled surface, the rafters 31 and 32 that respectively support the lower surfaces of the one and the other two roofs at the front-end | tip part which consists of this right-angled surface, especially the most corner | angular part of this corner The leading end of the conventional girder upper thermal insulation panel interferes with the rafters 31a, 32a and the valley 35 located near the corner, and close to the corner of the inner angle formed by the eaves girder 33, 34 and the valley 35 Cannot be constructed. On the other hand, the second upper thermal insulation panel 21 according to the embodiment of the present invention has two inclined surfaces, a first inclined surface 22c and a second inclined surface 22d, on the panel body 22 shown in FIG. 6 and 7, as shown in FIG. 6 and FIG. 7, the inclined lower part does not interfere with any of the two rafters 31a, 32a and the valley tree 35 orthogonal to each other at the valley part, It can be performed close to the corner of the inner angle formed by 34 and Tani 35. In the example of the construction using the second upper thermal insulation panel 21 shown in FIGS. 6 and 7, the panel main body 22 of the second upper thermal insulation panel 21 does not interfere with the rafters 31 and 32. Since the first inclined surface 22c and the second inclined surface 22d shown in FIG. 5 are formed, the lower surface of the valley 35 is formed by the formation of the first inclined surface 22c and the second inclined surface 22d, and Since interference with the vicinity of the valley bottom of the first inclined surface 22c and the second inclined surface 22d is also avoided, the first inclined surface 22c and the second inclination for avoiding interference of the valley 35 to the valley bottom. A third inclined surface different from the surface 22d is not particularly formed on the valley bottom of the second upper thermal insulation panel 21. As shown in FIG. 7, the second girder heat insulation panel 21 is also similar to the first girder heat insulation panel 1, with eaves girder 33 and 34 positioned near the corners of the corners and the illustrated figure. It is constructed on the structural plywood 30 placed on the upper surface of the beam that does not. The structural plywood 30 is a wooden plywood placed on the eaves girders 33 and 34 and a beam (not shown), and has the same size and shape as the bottom surface of the second girder thermal insulation panel 21. In other words, it is used as a pedestal for constructing the second girder thermal insulation panel 21. Moreover, as shown in FIG. 6, the above-mentioned first girder thermal insulation panel 1 and the structural plywood 10 are adjacent to both sides of the second girder thermal insulation panel 21 constructed at the corner of the corner. And it is constructed on the upper surface of the eaves 33 and 34 and the beam (not shown) on the lower surface of the entire roof.

  Next, the third upper thermal insulation panel 41 according to the embodiment of the present invention will be described. The third upper thermal insulation panel 41 has a cross-sectional configuration similar to that of the first upper thermal insulation panel 1, and a detailed description thereof will be omitted. As shown in FIG. 8, the third digit thermal insulation panel 41 is integrally formed from a panel body 42 made of urethane resin, two vacuum thermal insulation materials (not shown), and a plate-like thermal insulation material (not shown). Yes. That is, the third upper thermal insulation panel 41 includes a panel heat insulating material (not shown) and two vacuum heat insulating materials (not shown) laminated on the upper surface of the plate heat insulating material (not shown) embedded in the panel body 42. However, the outer shape of the panel main body 42 is the same as the panel main body 2 of the first upper thermal insulation panel 1 and the panel main body 22 of the second upper thermal insulation panel 21. It has a different shape. As shown in FIG. 8, the panel main body 42 of the third digit thermal insulation panel 41 includes a plate-like portion 42a and a first inclined portion 42b that is continuous with two orthogonal side surfaces of the plate-like portion 42a. The inclined surface 42c and the second inclined surface 42d, and the third inclined surface 42e formed at the corners of the first inclined surface 42c and the second inclined surface 42d are formed.

  The third girder thermal insulation panel 41 is also used for a building such as a house where the roof surface is inclined, like the first girder thermal insulation panel 1 and the second girder thermal insulation panel 21. However, the third girder thermal insulation panel 41 is formed by the two roof surfaces different from each other in the inclined direction and the roof surface being in contact with each other at the top of the inverted V shape (mountain shape). It is a case where it constructs about a corner part, Comprising: It is used when constructing about a corner part of what is called a corner. In addition, it may be necessary to construct such a projecting corner in a building having a structure in which the surface of the roof is inclined in four directions, such as a dormitory roof or a square roof.

  The roof in the vicinity of the corner of the corner where the two roof surfaces, the one roof surface and the other roof surface (both not shown) abut, is shown in FIG. 9 or FIG. As described above, the rafter 51 that supports the lower surface of one roof from below, the rafter 52 that supports the lower surface of the other roof from below, and the eaves girder 53 that respectively supports the lower end side middle portions of these rafters 51, 52. 54 and a corner tree 55 located below the boundary line (ridgeline) of the inverted V-shaped top formed by the contact of the surfaces of one and the other two roofs. The cross section of the corner tree 55 has a deformed pentagonal shape, and the rafters 51 and 52 that support the surface of one roof and the surface of the other roof are respectively supported on the left and right side surfaces of the corner tree 55 shown in FIG. The top of the is fixed. For this reason, when the above-mentioned conventional girder thermal insulation panel is used as the girder thermal insulation panel constructed in the portion closest to the eaves girder 53, 54 at the corner of the protruding corner, the tip portion has an inclined surface. Since it is not formed but is a right-angled surface, the rafters 51 and 52 and the corner tree 55 that support the lower surfaces of the one and the other two roofs interfere with each other at the tip portion formed by the right-angled surface. On the other hand, the third upper thermal insulation panel 41 according to the embodiment of the present invention has three first inclined surfaces 42c, a second inclined surface 42d, and a third inclined surface 42e shown in FIG. Since the inclined surface is formed, as shown in FIG. 9, neither the rafters 51 and 52 and the corner tree 55 having different inclination directions interfere with each other, and the eaves spar 53 and 54 and the corner tree 55 are formed. It can be performed close to the corner of the inner corner. In addition, as shown in FIG. 9 or FIG. 10, the third digit thermal insulation panel 41 also has a corner portion at the protruding corner, similar to the first digit thermal insulation panel 1 and the second digit thermal insulation panel 21. Is installed on the structural plywood 50 mounted on the eaves girder 53, 54 located near the upper surface of the beam and the upper surface of the beam (not shown). The structural plywood 50 is a wooden plywood placed on the eaves girders 53 and 54 and a beam (not shown), and has the same size and shape as the bottom surface of the third girder thermal insulation panel 41. In other words, it is used as a pedestal for constructing the third digit thermal insulation panel 41. Moreover, as shown in FIG. 9, the above-mentioned first girder thermal insulation panel 1 and the structural plywood 10 are adjacent to both sides of the third girder thermal insulation panel 41 constructed at the corners of the protruding corners. And it is constructed on the upper surface of the eaves 53 and 54 and the beam (not shown), which is the lower surface of the entire roof.

It is comprised by the nest | insert 62 which shape | molds the inclined surface 2c of the panel main body 2 which is accommodated in the body 61 and comprises the 1st digit heat insulation panel 1 shown in FIG. 1 or FIG. Among these, the molding frame 61 is formed in a rectangular shape that can accommodate the plate-like heat insulating material 6 in the four sides of the plate-like heat insulating material 6 inside the opening and can be accommodated horizontally. An injection port 61a for injecting a material (a liquid material of urethane resin) of the panel body 2 to be described later is penetrated through one of the four side walls. The four side wall portions of the forming frame body 61 are made of aluminum, and the bottom plate portion of the forming frame body 61 is made of stainless steel, and is formed on the bottom plate in the forming frame body 61 by a method described later. An air hole (not shown) for facilitating the demolding of the first upper thermal insulation panel 1 formed in (1) is formed. Further, the insert 62 is formed in a substantially triangular prism shape having a insert-side inclined surface 62a for forming the inclined surface 2c of the panel main body 2 shown in FIG. 1 or 2, and the inclined surface 2c of the panel main body 2 is formed. A flat surface 62b is formed on the top of the nesting-side inclined surface 62a, which bears the forming of the tip portion, shown in FIG. The insert 62 is made of wood and, as will be described later, in the portion that may be in direct contact with the liquid material of the urethane resin injected into the molding frame 61, the molded first upper thermal insulation is provided. A masking tape (not shown) is attached so that the panel 1 can be easily removed.

  As shown in FIG. 11, the manufacturing process of the first upper thermal insulation panel 1 is such that the forming frame body 61 is first installed horizontally, and a substantially triangular prism-like insert 62 is inserted into the forming frame body 61. The nesting side inclined surface 62a corresponding to the inclined surface 2c of the panel main body 2 is disposed on the opening side. The height of the insert 62 (the distance between the bottom surface and the flat surface 62b) is such that the flat surface 62b coincides with the upper surface of the opening of the forming frame 61 when the insert 62 is disposed.

  Next, as shown in FIG. 12, a non-woven fabric 63 made of polyethylene terephthalate is spread on the bottom surface of the molding frame 61 and the nesting side inclined surface 62a of the nesting 62, and on the inner surface of the molding frame 61. A wax-like mold release for easily demolding the first girder thermal insulation panel 1 molded in the molding frame 61 at a location where the nonwoven fabric 63 is not located (such as a side wall of the molding frame 61). Apply the agent. Thereafter, four mounting tables 64 are arranged on the nonwoven fabric 63 in the forming frame body 61. The four mounting tables 64 are each formed in a columnar shape having the same height, and are formed of the same material as the urethane resin of the panel body 2 and are poured into the forming frame 61 in a later step. Integrated with resin.
