  In a wooden or steel-framed building, because it is excellent in workability and can exhibit sufficient proof stress, a heat insulating panel with a standard size in which heat insulating material is preliminarily stored in a rectangular frame such as a wooden frame is used as a pillar. The construction method which arrange | positions between a wall and a joist and comprises a wall and a floor has prevailed. In the heat insulation panel as described above, in order to further improve the heat insulation performance, a so-called thin plate-like material in which a core material (filler) such as silica is accommodated in a flat bag made of a gas barrier film and the inside of the bag is evacuated. Various uses of a vacuum heat insulating plate have been studied, and such a vacuum heat insulating plate is used in combination with a foamed resin heat insulating material from the viewpoint of preventing leakage due to damage of the surface film and further improving the heat insulating performance.

As a heat insulation panel which used a vacuum heat insulating board and a foamed resin heat insulating material together, the heat insulating panel which covered the whole surface (front-and-back surface and thickness part) of the vacuum heat insulating board with the heat insulating material of the polystyrene-type foamed resin is mentioned, for example. In the manufacture of such a heat insulating panel, a plurality of block-like supports made of a foamed resin molded body and provided with concave grooves are arranged on the outer peripheral portion in the cavity of the molding die, and vacuum is formed in the concave grooves of these supports.

At that time, in the present invention, by using a vacuum heat insulating plate having a plane size corresponding to the inner edge length of the wooden frame, the vacuum heat insulating plate is accommodated in the wooden frame without any gap, and at a predetermined position in the wooden frame. By simultaneously foaming the raw material resin on both sides of the supported vacuum heat insulating plate, deformation and bias of the vacuum heat insulating plate in the wooden frame were prevented.

That is, the gist of the present invention is that a wooden frame formed into a rectangular shape by a vertical frame and a horizontal frame, a vacuum heat insulating plate housed in the wooden frame, and a clothing on both sides of the vacuum heat insulating plate housed in the wooden frame. A heat insulating panel for building mainly composed of a heat insulating material made of foamed resin, wherein the vacuum heat insulating plate is stored in the wooden frame without a gap, and the heat insulating material is the vacuum heat insulating plate. of which the raw material resin is formed by foaming it and filled on both sides, and that when manufacturing the building thermal insulation panels, said vacuum insulation plate plane dimension corresponds to the inner edge length of the crate A square-shaped support material made of a foamed resin molding and housed in the wooden frame is arranged on both sides of the vacuum heat insulating plate along the inner edge, and the wooden frame is moved by two press plates of a molding machine.

Since the material is formed, a higher shielding effect against heat is obtained, and a further excellent heat insulating performance is obtained. Moreover, according to the manufacturing method of the heat insulating panel for building according to the present invention, the vacuum heat insulating plate is housed in the wooden frame without gaps, and is supported on the both surface sides of the vacuum heat insulating plate from the both surface sides by the square-shaped support material.

Are provided along the thickness direction of the horizontal frame. A pair of resin filling holes (1c) are respectively provided in both parallel horizontal frames (11). The resin filling hole (1c) of one horizontal frame (11) is used when filling the raw material resin, and the resin filling hole (1c) of the other horizontal frame (11) is used as a deaeration hole.

  After preparing the wooden frame (1), as shown in FIG. 5 (b), a square-shaped support material (2) containing a vacuum heat insulating plate (3) in the wooden frame (1) and made of a foamed resin molded body. ) Are arranged on both sides of the vacuum heat insulating plate (3) along the inner edge of the wooden frame (1). And a wooden frame (1) is clamped from the thickness direction with two press plates (5) of a molding machine (illustration of a main body is abbreviate | omitted).

  Specifically, as shown in FIG. 2, first, the support member (2) is arranged along the inner edge of the wooden frame (1). In that case, the support material (2) is biased toward the bottom surface side of the wooden frame (1) in a state where the one surface side of the wooden frame (1) is down, that is, in a state in which the wooden frame (1) is viewed in plan. Arrange in a state. As the support material (2), a material previously foamed with the same material as the heat insulating material (7) described later is used. Width of support material (2) (cross-sectional length along the surface direction of the heat insulation panel in a state orthogonal to the length direction of support material (2) and along the vertical frame (10) and the horizontal frame (11)) Is designed to be 10 to 50 mm, and is designed to have a thickness of the support member (2) (a cross-sectional length of the support member (2) along the thickness when a heat insulating panel is formed) of 30 to 130 mm.

  Further, for example, in the support material (2) arranged along the horizontal frame (11), the resin filling hole (2c) overlapping the resin filling hole (1c) is formed at the center of the length of the support material. It is provided in the corresponding part. Similarly to the resin filling hole (1c) of the wooden frame (1), the resin filling hole (2c) is provided in the support member (2) along each horizontal frame (11). The support material (2) is fixed to the inner edge of the wooden frame (1) with an adhesive or an adhesive.

After the support material (2) is stored in the wooden frame (1), the vacuum heat insulating plate (3) is disposed on the support material (2) as shown in FIG. The vacuum heat insulating plate (3) is formed in a plate shape by enclosing a core material (filler) with a gas barrier film and evacuating the inside. The structure of the vacuum heat insulating plate as described above is well known and is disclosed in Japanese Patent Publication Nos. 2000-507340, 2005-106090, 2007-056547, and the like.

  In the vacuum heat insulating plate, a multilayer film having an aluminum layer having a thickness of about 10 to 15 μm is used as the gas barrier film. The layer structure of such a multilayer film is, for example, high-density polyethylene (heat-bonding layer) / aluminum (gas barrier layer) / polyethylene terephthalate (reinforcing layer) / high-density polyethylene (heat-bonding layer), or polyethylene / aluminum / Polyester polyethylene / aluminum / polyethylene / polyester polypropylene / aluminum / polyester. In addition, examples of the core material include inorganic powders such as silicic acid, silica gel and fly ash, inorganic fibers such as glass wool, resin foams such as urethane, styrene and ethylene, and polyurethane rigid foam powder. It may be pre-compressed to enhance the properties.

  As said vacuum heat insulation board (3), the dimension of the plane dimension corresponds to the length and width of the inner edge of a wooden frame (1) is used. That is, on the wooden frame (1), a vacuum heat insulating plate (3) having a size that fits in the wooden frame without a gap in a plan view is disposed. In the present invention, the state where there is no gap between the vacuum heat insulating plate (3) disposed on the wooden frame (1) and the wooden frame refers to the heat insulating material (7) on one side of the wooden frame (1) and the like. When foam-molding the surface-side heat insulating material (7) (see FIG. 6 (b)), the raw material resin penetrates between the edge of the vacuum heat insulating plate (3) and the wooden frame (1), and the above-mentioned As long as the two heat insulating materials (7) are not connected, a slight gap may be present, and the size of the gap is preferably 5 mm or less. The thickness of the vacuum heat insulating plate (3) is designed to be 15 mm or less, preferably 5 to 10 mm in consideration of heat insulating performance and weight reduction required as a building material.

  After the vacuum heat insulating plate (3) is arranged, as shown in FIG. 4, the same support material (2) as the above-mentioned support material (support material shown in FIG. 2) is placed along the inner edge of the wooden frame (1). And arrange from the upper surface side of the vacuum heat insulating plate (3). That is, said support material (2) is arrange | positioned in the state biased to the upper surface side of the wooden frame (1) in the state which planarly viewed the wooden frame (1). Also, among the support material (2) shown in FIG. 4, for example, as the support material (2) along each horizontal frame (11), a resin filling hole (2c) is provided as in the support material shown in FIG. Use what is provided. In addition, the support material (2) shown in FIG. 4 is also fixed to the inner edge of the wooden frame (1) with an adhesive or a pressure-sensitive adhesive, similarly to the support material described above.

  In addition, each support material (2) on the lower surface side and the upper surface side of the vacuum heat insulating plate (3) is vacuumed at a predetermined position in the wooden frame (1) when foaming raw material resin of the heat insulating material (7) described later. Arranged to hold the thermal insulation plate (3). Therefore, in the normal case where the vacuum heat insulating plate (3) is arranged at a position corresponding to the center of the thickness of the wooden frame (1), each support material (2) on the lower surface side and the upper surface side of the vacuum heat insulating plate (3). In the case where both of them are designed to have the same thickness and the vacuum heat insulating plate (3) is arranged at a position deviated from the center of the thickness of the wooden frame (1), each of the support materials (2 ) Are used with different thicknesses.

  The wooden frame (1) containing the vacuum heat insulating plate (3) and the supporting material (2) as described above is loaded into a molding machine and sandwiched between the press plates (5) as shown in FIG. In such an operation, the pressing force of the press plate (5) is adjusted to such an extent that the wooden frame (1) is not damaged and can withstand the foaming pressure of the raw material resin. By the above operation, both sides of the wooden frame (1) (the front side and the back side when the heat insulating panel is formed) are covered with the two press plates (5), and the vacuum heat insulating plate (3) in the wooden frame (1) is covered. Space portions for filling the raw material resin of the heat insulating material (7) are formed on both sides.

As the molding machine, for example, a multi-stage press molding machine that simultaneously pressurizes a plurality of objects to be processed with a press plate in the vertical direction can be used. Although not shown in the drawings, such a molding machine includes a base on which a flat plate-like first press plate is horizontally disposed, and a plurality of hydraulic pressures that are disposed above the base and can be advanced and retracted in the vertical direction. A pressurizing device including a cylinder, and second to sixth press plates arranged in parallel with the first press plate above the base and connected sequentially from the first press plate via a link. In addition, the rod tip of each hydraulic cylinder is connected to the uppermost sixth press plate, and the second to sixth press plates are raised by the retreat of the hydraulic cylinder, whereby the first to sixth Five pressurizing process spaces are formed between the press plates, and the second to sixth press plates are lowered by the advancement of the hydraulic cylinder, so that the workpieces loaded in the pressurizing process spaces can be simultaneously treated at a constant pressure. It is configured to hold under pressure.

  In addition, as shown in FIG. 5, when the wooden frame (1) is loaded into the molding machine, protection for preventing adhesion of the raw material resin between the upper and lower press plates (5) and the wooden frame (1). It is preferable to interpose a sheet (4). As the protective sheet (4), a film or sheet made of aluminum, kraft paper, various synthetic resins or the like is used. The size of the protective sheet (4) is slightly narrower than the external dimensions of the wooden frame (1). The protective sheet (4) is usually attached to both sides of the wooden frame (1) with an adhesive or an adhesive. When the protective sheet (4) is interposed, it is possible to prevent the material resin of the heat insulating material (7) described later from adhering to the press plate (5) and to protect the heat insulating material (7) in the manufactured heat insulating panel. In addition, a heat shielding effect can be obtained.

  Next, as shown in FIG. 6, the raw material resin filling nozzle (6) (in FIG. 6) is inserted into one of the pair of resin filling holes (1c) provided in the horizontal frame (11) of the wooden frame (1). Install the nozzle shown by the solid line. As the raw material resin filling nozzle (6), for example, a two-fluid mixing nozzle is attached to the tip, and the two raw material compositions such as isocyanate and polyol described later supplied from one set of flexible pipes are mixed with each other as described above. What is constituted so that injection | emission is possible is used for the space part. And in this invention, with respect to said space part formed in the both surfaces side of a vacuum heat insulating board (3), it fills with the raw material resin which comprises the same quality foam resin as a support material (2), and it is made to foam simultaneously. Thereby, a heat insulating material (7) is formed.

  Examples of the foamed resin constituting the heat insulating material (7) include urethane resin, phenol resin, and polyethylene resin. Usually, a polyurethane resin is used in order to increase heat insulation and strength and to reduce weight. As is well known, in polyurethane foaming, polyisocyanate and polyol are mixed with a catalyst such as an amine compound, a foaming agent such as water or fluorocarbon, a foam stabilizer such as silicon oil, and the like, thereby forming a bubble and a resin. Are simultaneously advanced to obtain polyurethane foam. In filling the raw material resin, the space portion is filled while mixing the polyisocyanate supplied from a foaming device including a pressure pump and a foaming raw material such as polyol by the raw material resin filling nozzle (6).

  In the present invention, the filled raw resin is simultaneously foamed into the spaces formed on both sides of the vacuum heat insulating plate (3) while holding the wooden frame (1) with the press plate (5) of the molding machine. Therefore, it is possible to arrange the vacuum heat insulating plate (3) at a predetermined position in the wooden frame (1) without deviation and to prevent deformation of the vacuum heat insulating plate (3) such as bending.

  In the present invention, the simultaneous foaming of the raw material resin is a concept including the following time difference. That is, the time difference is the start of foaming of the raw material resin filled in the space portion on the one surface side of the vacuum heat insulating plate (3), and the raw material resin filled in the space portion on the other surface side of the vacuum heat insulating plate (3). It is a time difference from the start of foaming, and the expansion force due to foaming of one raw material resin and the expansion force due to foaming of the other raw material resin are appropriately offset via the vacuum heat insulating plate (3), and the vacuum heat insulating plate ( This is an allowable time difference as long as the deformation or bias of 3) does not occur. Specifically, although it varies depending on the raw material composition, the environmental temperature, the injection flow rate, etc., it is usually 5 seconds or less, preferably 3 seconds or less, due to the time difference of starting filling of the raw material resin into each space.

  Therefore, in the raw material resin filling operation, as long as it is performed within the above time difference range, the raw material resin is filled in the space portions on both sides of the vacuum heat insulating plate (3) using one raw material resin filling nozzle (6). You can also That is, as shown by a solid line in FIG. 6A, after filling the raw resin into one space from one resin filling hole (1c) of the horizontal frame (11), within the above time difference range, FIG. As indicated by a virtual line in a), the other resin filling hole (1c) may be reattached with the raw material resin filling nozzle (6) to fill the other space with the raw material resin.

  By filling the wooden frame (1) with the raw material resin and foaming as described above, the foamed resin is integrated with the support material (2) having the same composition as shown in FIG. 6 (b). To do. Then, the foamed resin is allowed to stand for a certain time to be completely cured, thereby forming a foamed resin heat insulating material (7) integrated with the support material (2) on both sides of the vacuum heat insulating plate (3). A heat insulation panel can be constructed. The manufactured heat insulation panel is taken out by opening the press plate (5) of the molding machine. In addition, in the filling and foaming of the raw material resin, five heat insulating panels can be manufactured simultaneously by using, for example, a five-stage molding machine as described above.

  In the above manufacturing example, the vacuum heat insulating plate (3) and each support material (2) are previously stored in the wooden frame (1), and the wooden frame (1) is loaded in the molding machine. The wooden frame (1) is placed on the press plate (5) of the molding machine in an open state, and one supporting member (2), the vacuum heat insulating plate (3) and the other supporting member (2) are sequentially placed on the wooden frame. After storage, the wooden frame (1) may be sandwiched between press plates (5), filled with raw material resin, and foamed.

  As described above, in the production method of the present invention, the vacuum heat insulating plate (3) is stored in the wooden frame (1) without any gap, and the square-shaped support material (2) which is a foamed resin molded body from both sides of the vacuum heat insulating plate. ), The material resin filled on both sides of the vacuum heat insulating plate (3) is simultaneously foamed to form a heat insulating material (7) of uniform thickness integrated with the support material (2). To do. Therefore, according to the manufacturing method of the present invention, it is possible to manufacture a heat insulating panel that has a high heat shielding effect and is further excellent in heat insulating performance. And the heat insulation panel obtained by said manufacturing method has a vacuum heat insulating board (3) stored without gap with respect to a wooden frame (1), fills both surfaces of a vacuum heat insulating board (3) with raw material resin, and this Is formed to form a heat insulating material (7) having a uniform thickness. Therefore, according to the heat insulation panel of this invention, the higher shielding effect with respect to a heat | fever is acquired, and the further more heat insulation performance is obtained. Moreover, the peripheral part of the vacuum heat insulating board (3) embedded in the heat insulating material (7) is protected by the wooden frame (1), and is not damaged after construction during construction.

That is, the wooden frame (1) forms one frame by one vertical frame (10), an intermediate vertical frame (12), and two parallel horizontal frames (11), and the other vertical frame (10), intermediate The vertical frame (12) and two parallel horizontal frames (11) constitute another frame. The constituent materials and the assembly method of the vertical frame (10), the horizontal frame (11) and the intermediate vertical frame (12) are the same as those in the first embodiment. Usually, the outer length of the long side portion of the wooden frame (1) is designed to be 500 to 3000 mm, and the outer length of the short side portion is designed to be 400 to 1000 mm.

In addition, a square-shaped support material (2) made of a foamed resin molded body is disposed on both sides of each vacuum heat insulating plate (3) along the inner edge of each frame, and the support material ( 2) is sandwiched from the thickness direction. And the space part for raw material resin filling of a heat insulating material (7) is each formed in the both surface side of the vacuum heat insulating board (3) of each frame in a wooden frame (1).

  In addition, the structure of the support material (2) arrange | positioned on both surfaces side of each vacuum heat insulating board (3) is the same as that in the 1st aspect. Further, when loading the wooden frame (1) into the molding machine, the same protective sheet (4) for preventing the adhesion of the raw material resin as that in the first aspect is placed between the upper and lower press plates and the wooden frame (1). It is preferable to intervene. In that case, as a protection sheet (4), you may use the thing of the area which covers two frames individually on both surfaces of a wooden frame (1), respectively, and from a viewpoint of improving manufacturing efficiency, each frame is used.
