Description

  The present invention relates to a heat insulating panel and a mounting method for mounting the heat insulating panel on a wall surface of a building. In particular, a step is generated between adjacent heat insulating panels mounted on the wall surface, or cement paste at the time of wall construction is a surface of the heat insulating panel. The present invention relates to a heat insulating panel that can easily eliminate a step or remove a cement paste without damaging the heat insulating panel, and a method for attaching the heat insulating panel.

  When a thermal insulation panel is attached to the wall of a building and wet construction materials such as mortar are applied to the surface of the thermal insulation panel, a thermal insulation panel in which a lath such as a metal lath or wire lath is fixed in advance to the surface of the thermal insulation panel is applied May be. By adhering the lath to the surface of the heat insulating panel, the adhesion between the heat insulating panel and the wet building material when applying the wet building material can be enhanced.

  For example, Patent Documents 1 and 2 can be cited as conventional techniques related to the above-described heat insulation panel. The technique disclosed in Patent Document 1 relates to a heat insulating panel that also serves as a mold. This heat insulation panel has a mesh material fixed to at least one side of a polystyrene resin foam, and this mesh material is made of a chemical fiber mesh or a metal mesh. It is fixed by thermal lamination. By fixing the net material having such specifications to the resin foam in such a fixing form, the bending strength and impact resistance of the mold can be increased, and the transportability and work efficiency can be improved.

  On the other hand, the technique disclosed in Patent Document 2 relates to a foamed resin board for construction in which a lath is integrally fused to the surface of the foamed resin board. Since the lath is fused and integrated with the foamed resin board, the lath is not easily peeled off, and the strength of the board itself can be increased. In addition, by forming the board from foamed resin, heat insulation and waterproofing can be improved, and it is not necessary to install a separate heat insulating material or waterproof sheet when constructing walls and floors of buildings, etc. It can be improved.

  The heat insulating panel also used as a formwork disclosed in Patent Document 1 and the foamed resin board for construction disclosed in Patent Document 2 are both firmly integrated into a net or lath to a panel such as resin foam or foamed resin board. It is fixed. When such a heat insulating panel is applied, although the method of attaching the heat insulating panel differs between the two heat insulating panels, there may be problems inherent to each.

  First, when constructing a wall of a building, as a problem when applying the heat insulating panel disclosed in Patent Document 1 as a heat insulating panel also used as a formwork, cement paste (so-called Noro) passes between adjacent heat insulating panels. The difficulty in repairing when it flows out to the finished surface side of the heat insulation panel (surface opposite to the wall surface) is mentioned. That is, since the net material is firmly fixed to the resin foam, it is impossible to peel only the net material without damaging the resin foam. Therefore, the cement paste that is entangled with the mesh material and is not necessary for finishing cannot be removed. Conversely, if the mesh material is peeled off from the resin foam for removal, the resin foam is damaged by the peeling force of the mesh material. It is inevitable.

  On the other hand, when the foamed resin board disclosed in Patent Document 2 is pasted on the surface after the wall has been constructed, there is a possibility that a level difference will occur between adjacent foamed resin boards due to unevenness of the wall surface caused by construction errors. There is sex. Furthermore, the same level | step difference will arise because the adhesive agent for affixing a foaming resin board on a wall surface is apply | coated unevenly. In this case, since the foamed resin board and the lath are firmly fixed, it is not possible to repair by removing the lath and scraping the surface of the board to eliminate the step. For example, the surface finish material such as the above must be applied relatively thick. The board whose thickness of the surface finish is increased is loaded with the weight of the surface finish, and as a result, a relatively large shear force acts on the board. Further, lath is generally applied for the purpose of preventing cracking of the surface finish and improving adhesion to the board, and a material having poor stretchability is generally applied. By fixing this to the heat insulation board, when the heat insulation board is attached to the curved wall surface, the force that tends to extend on the lath side surface of the heat insulation board is suppressed by the lath, and on the wall surface side of the heat insulation board. Compared to a large compressive force. Therefore, a distorted internal stress is generated inside the board, and there is a problem that durability of the board itself is lowered.

  The heat insulating panel and the method for attaching the heat insulating panel of the present invention have been made in view of the above-described problems, and a step is generated between adjacent heat insulating panels attached to the wall surface, or the cement paste at the time of wall construction is the heat insulating panel. A heat insulating panel that can easily eliminate a step or remove cement paste when it adheres to the surface of the steel, and does not damage the heat insulating panel (heat insulating material) during the repair, and the heat insulating panel The purpose is to provide a mounting method.

  In order to achieve the above-mentioned object, the heat insulating panel according to the present invention is attached to one surface of a panel-like heat insulating material made of foamed resin through a pressure-sensitive adhesive so that the mesh material can be peeled off and can be re-adhered. It is characterized by becoming.

  The building to which the heat insulation panel of the present invention is applied covers general buildings such as general houses and buildings as well as public facilities such as water and sewage buildings, and its structural form is wooden, steel frame Any form of manufactured (S structure), reinforced concrete (RC structure), and steel-framed reinforced concrete (SRC structure) may be sufficient. Furthermore, this heat insulation panel can be applied to both the inner heat insulation method and the outer heat insulation method.

Examples of the foamed resin material as the material for the heat insulating material include polystyrene foam, polyethylene foam, polypropylene foam, rigid urethane foam, phenol foam, isocyanate foam, and epoxy foam. This heat insulating material can be formed by an extrusion foam molding method, a foam bead-in-mold foam molding method, or the like. Moreover, although the density can be set to a suitable value according to required heat insulation performance, about 10-100 kg / m < ³ > is preferable, for example. Furthermore, the thickness and plane dimensions of the heat insulation panel are not particularly limited, and can be appropriately selected according to design specifications, construction environment, etc. Examples of the configuration applied to the shape include an L-shaped cross-sectional view and a curved shape as a whole.

  A heat insulating panel of the present invention is formed on one surface of the panel-like heat insulating material by attaching a netting material via an adhesive. Here, the netting material can be formed from glass fiber, metal fiber, synthetic resin fiber or the like, and is preferably formed from an alkali-resistant fiber material or a fiber material subjected to an alkali-proof treatment on the surface. Further, it is preferable to form a net material by so-called leno weaving, in which warps and wefts made of such a fiber material are knitted together. By entangled weave, it is possible to form a net material that is less prone to misalignment. Moreover, the adhesion of a heat insulation panel and wet building materials can be improved by sticking a net | network material to a heat insulating material, Furthermore, the crack of wet building materials can be suppressed.

  It is desirable that an appropriate pressure-sensitive adhesive that can be peeled off one or more times and adhered to the surface of the heat insulating material each time is applied or pasted on one side of the above-mentioned net material. As the pressure-sensitive adhesive, rubber-based or acrylic resin-based materials such as solvent-type, emulsion-type, hot-melt type, and reaction-type pressure-sensitive adhesives can be used. The heat insulating panel of the present invention is formed by adhering the panel-like heat insulating material made of foamed resin and the netting material through such an adhesive. In addition, the adhesive strength between the heat insulating material and the netting material requires at least an adhesive strength that prevents the netting material from peeling off from the heat insulating material due to the weight of the wet building material such as mortar to be applied to the surface of the netting material. It is desirable that an operator should have an adhesive strength that can be easily removed when the mesh material is removed from the heat insulating material during repair.

  In addition, one side of the heat insulating material to which the netting material is stuck is formed with fine irregularities on the surface by nichrome cutting or sanding, etc., thereby increasing the adhesion area with the wet building material and increasing the adhesion force Can be increased. Furthermore, the contact end surfaces of the adjacent heat insulation panels are formed in an appropriate form in which both end surfaces can be fitted to each other, so that when the wall concrete is placed, the cement paste is removed from the contact end surface. It can be made difficult to leak.

  According to the heat insulating panel of the present invention, even when a step is generated between adjacent heat insulating panels attached to the wall surface of a building, the net material is easily peeled off from the heat insulating material, for example, the surface of the protruding heat insulating material is shaved. However, the step can be eliminated, and the netting material can be pasted again on the surface of the heat-insulated material. Further, even when the cement paste leaks from between the heat insulating panels and hardens between the net material and the heat insulating material, the net material can be peeled off, the cement paste can be scraped off, and the net material can be pasted again. Since the mesh material can be easily peeled off from the surface of the heat insulating material, the surface of the heat insulating material can be repaired very easily without damaging the heat insulating material.

  Moreover, the preferable embodiment of the heat insulation panel by this invention is characterized by the said net | network material being affixed on the said heat insulating material with the peeling strength of 20-750 gf / 20mm width.

  According to the peel test described later by the inventors, (1) the adhesive strength (peeling strength) when the mesh material is peeled once from the heat insulating material and again adhered, and (2) the net material is peeled from the heat insulating material. A heat insulating panel in which a 20 mm-wide mesh material is adhered to a heat insulating material with a peel strength of 20 to 750 gf is a preferred embodiment that satisfies both elements. It was proved.

  According to the above test, when the netting material is less than 20 gf / 20 mm width and adhered to the heat insulating material, re-adhesion is impossible, or even if it can be re-adhered, it is natural due to the weight of wet building materials such as mortar. This is not preferable. On the other hand, when the peel strength is larger than 750 gf / 20 mm width, it is difficult to remove the net when the operator peels off the netting material, and this is not preferable because of a sensory result that workability is lowered.

  In a preferred embodiment of the heat insulation panel according to the present invention, the pressure-sensitive adhesive is made of an acrylic copolymer aqueous emulsion.

  By applying a pressure-sensitive adhesive made of an acrylic copolymer aqueous emulsion, it is possible to achieve adhesion between the heat insulating material and the netting material in the above-described peel strength range, and the workability is extremely good.

  The heat insulating panel mounting method according to the present invention is a construction of a heat insulating panel comprising a panel-shaped heat insulating material made of foamed resin, and a net material that can be peeled and re-adhered to one surface thereof. A method for attaching a heat insulating panel to be attached to a wall surface of an object, wherein a form for installing a wall is installed, and a plurality of heat insulating panels are attached to a predetermined form surface so that the net is on the form side. And when the cement paste leaks to the netting side of the heat insulating material, the second step of placing the concrete in the mold and demolding after waiting for its hardening The method further includes a third step of removing a part of the mesh material of one or both of the heat insulation panels, removing the cement paste from the surface of the heat insulation material and the mesh material, and re-adhering the peeled mesh material to the heat insulation material. It is characterized by.

  In the method for attaching a heat insulating panel according to the present invention, a heat insulating panel described above is attached in advance to a formwork to be installed when constructing a wall of a building, and concrete for the wall is placed in the formwork, This is an attachment method in which a heat insulation panel is attached to a wall surface by removing the mold after waiting for curing.

  As described above, when concrete is placed, cement paste may leak from between adjacent thermal insulation panels, and this cement paste penetrates between the thermal insulation material and the mesh material of the thermal insulation panel. Cured with. In this case, the cement paste closes the mesh of the mesh material provided for the purpose of enhancing the adhesion between the heat insulating panel and the wet building material, and the adhesion is hindered. Furthermore, the uneven surface formed on the surface of the heat insulating material is similarly blocked by the cement paste. Cement paste is made of cement with a lot of water and has extremely low strength (adhesion strength and compressive strength), so it must be removed before applying wet building materials.

  Therefore, if the cement paste is leaked / hardened, remove the mesh material where repair is required from the surface of the heat insulating material, remove the cement paste by sanding or suspending, etc., and insulate the removed mesh material again. By sticking on the material surface, it is possible to ensure a desired adhesion force between the wet building material to be applied later and the heat insulating panel (minimum adhesion force required at the time of re-adhesion).

  Furthermore, another embodiment of the method for attaching a heat insulating panel according to the present invention is a panel-shaped heat insulating material made of foamed resin, and a net material that can be peeled and re-adhered to one surface thereof, A heat insulating panel mounting method for mounting a heat insulating panel comprising: a first step of constructing a building wall; and a second step of attaching a plurality of heat insulating panels to a wall surface. If there is a step between adjacent heat insulation panels, remove part of the mesh material of one or both of the heat insulation panels, eliminate the step while scraping the surface of the heat insulation material, and peel off the mesh material The method further includes a third step of re-adhering to the heat insulating material.

  The heat insulating panel mounting method according to the present invention is a method in which a wall of a building is first constructed and the heat insulating panel is attached to the wall surface. As a method for attaching the heat insulation panel to the wall surface, an adhesive layer is formed on the wall surface, and the heat insulation panel is attached via the adhesive layer, or a sticking tool such as a nail or an anchor bolt is used. The method of attaching, and the method of using these together are mentioned.

  For example, in the case of a method of attaching a heat insulation panel via an adhesive layer, it is extremely difficult to form the thickness of the adhesive layer uniformly over the entire wall surface, and the thickness of the adhesive layer is not uniform. It is unavoidable to become. When the thickness of the adhesive layer is not uniform, for example, there is a high possibility that a step is generated between adjacent heat insulating panels. In addition, the wall surface itself may have a step due to construction errors. Problems when a step is generated between the heat insulating panels are as described above.

  Therefore, in the present invention, when a step is generated between adjacent heat insulating panels, a part of the net material of one or both heat insulating panels is peeled off, and the surface of the protruding heat insulating material is shaved. The level difference is eliminated, and then the peeled net is pasted again on the surface of the heat insulating material. By eliminating the step between the heat insulating panels, the problem that the application amount of the wet building material is biased toward the one heat insulating panel can be effectively solved.

  As can be understood from the above description, according to the heat insulating panel and the method for attaching the heat insulating panel of the present invention, the step between adjacent heat insulating panels attached to the wall surface of the building is eliminated without damaging the heat insulating material. Or the cement paste that has leaked / hardened to the surface of the insulation panel during wall construction can be removed.

  Embodiments of the present invention will be described below with reference to the drawings.

In addition, the shape of the heat insulation panel is not limited to the illustrated embodiment, and can be formed into an appropriate shape according to the shape of the wall to be mounted, and the shape of the end surface thereof is adjacent to the heat insulation panel. It may be a form in which a plurality of protrusions or concave grooves that can be fitted to the end face of each other are formed.

  FIG. 1 shows an embodiment of a heat insulating panel. This heat insulation panel 10 is comprised from the heat insulating material 1 which consists of arbitrary foamed resin materials, and the net | network material 2 adhere | attached on the surface. Examples of the material for the heat insulating material 1 include polystyrene, polyethylene, polypropylene, hard urethane, phenol, isocyanate, and epoxy. Moreover, the manufacturing method can be formed by an extrusion foam molding method, a foam bead in-mold foam molding method, or the like.

  For example, a pressure-sensitive adhesive 3 made of an acrylic copolymer aqueous emulsion is applied or pasted on the surface on which the mesh material 2 is adhered to the heat insulating material 1, and the mesh material 2 adhered to the heat insulating material 1 is attached to the surface. It peels off and can adhere | attach the net | network material 2 to the heat insulating material 1 again.

  FIG. 2 is an enlarged view of a portion II in FIG. 1 and illustrates the net 2 in detail. The mesh material 2 is made by bundling fibers 21a, 21a,... Such as glass fibers, metal fibers, synthetic resin fibers, and the like, and warp materials 21, 21,. Are produced by entwining and weaving the weft materials 22, 22,. For example, as shown in the drawing, it can be formed in a form in which the weft materials 22, 22,... Are passed through the respective through portions of the warp materials 21, 21,. be able to.

  For example, the pressure-sensitive adhesive 3 is preliminarily applied or pasted on the surface (location) of the warp material 21 that comes into contact with the heat insulating material 1, and the net material 2 is heat-insulated by a method such as pressing with a roller as described later. Panel 10 is produced.

  FIG. 3 is a diagram schematically showing a method of manufacturing the heat insulating panel 10 by adhering the net material 2 to one surface of the panel-shaped heat insulating material 1.

  The heat insulating materials 1, 1,... Are sequentially conveyed on the rollers 65, 65,. On the other hand, the long net member 2 in which the pressure-sensitive adhesive is previously applied on one surface is wound around a roll 64. The nets 2 are sequentially attached to the surfaces of the heat insulating materials 1, 1,... To rotate the roll 64 in the Y1 direction, and the net 2 is supplied via the separate roll 63 (Y2 direction). Among the rollers 65, 65,..., The area where the mesh material 2 is adhered to one surface of the heat insulating material 1 that has been conveyed is adhered while pressing the mesh material 2 positioned on the heat insulating material 1 from above and below. Two opposing pressure rolls 61 and 62 are provided for the purpose of the operation. The pressure rolls 61 and 62 are configured to be movable up and down (Z direction), and the pressurizing force is adjusted by forming an appropriate roll clearance with respect to the thickness of the heat insulating material 1 that passes through both of the pressure rolls 61 and 62. It has become so.

  After the net material 2 is attached to one side of each of the heat insulating materials 1, 1,..., The net material 2 is cut into the size of the heat insulating material 1 with a cutter (not shown), and the heat insulating panels 10, 10,. ... are manufactured sequentially.

  Drawing 4 is a figure explaining the situation where heat insulation panels 10A and 10A of other embodiments are attached to one side of wall 4 of a completed building. The heat insulating panel may be attached to the outside of the wall by an outer heat insulating method, or may be attached to the inside of the wall by an inner heat insulating method.

  Of the heat insulating material 1a that constitutes the heat insulating panel 10A, an uneven surface 1a1 that can be fitted between the end surfaces is formed on the end surface that makes contact with the adjacent heat insulating panel 10A. By setting it as such a fitting structure, the connection strength of heat insulation panels can be raised. Further, in the case of the construction method in which the heat insulating panels 10A, 10A,... Are mounted in the formwork for building the wall of the building and the concrete is placed in the formwork, the cement is formed from the gap between the adjacent heat insulating panels 10A, 10A. It is possible to effectively prevent the paste from leaking.

  As shown in the drawing, the adhesive 5 is applied to one side of the wall, and the heat insulating panels 10A, 10A,... Are sequentially attached while fitting the concavo-convex portions 1a1, 1a1 on both end surfaces.

  FIG. 5 is a diagram schematically showing a repair method when a step is generated between adjacent heat insulating panels in the method of attaching the heat insulating panels to the wall of the building as shown in FIG.

  First, FIG. 5 a shows a state in which a step t is generated between the heat insulating panels 10 and 10 due to uneven thickness of the adhesive 5 applied to the wall surface. In addition to the non-uniform thickness of the adhesive 5, the surface may be uneven due to construction errors during wall construction, and a step may be generated between the heat insulating panels.

  In order to eliminate this level difference t, as shown in FIG. 5b, the net member 2 of the protruding heat insulating panel 10 is peeled from the heat insulating material 1 by a predetermined range.

  After part of the mesh material 2 is peeled off from the heat insulating material 1, as shown in FIG. 5c, the step t is eliminated by scoring or sanding the surface of the protruding heat insulating material. For example, it can be repaired so that both adjacent ends are rubbed as shown.

  After eliminating the level difference t, as shown in FIG. 5d, the repair work for eliminating the level difference is completed by re-adhering the peeled net 2 to the surface of the heat insulating material 1 after repair.

  Even in the case where the building wall and the heat insulation panel are integrally attached within the formwork, and the cement paste is leaked / cured to the side of the heat insulation panel to which the mesh material is adhered, the net It can be repaired by removing a part or all of the material, removing the cement paste from both the mesh material and the heat insulating material, and re-adhering the net material to the heat insulating material.

  As the heat insulation panel, extruded polystyrene foam (JIS A9511 XPSb type 3 (manufactured by Sekisui Plastics Co., Ltd.), 30-50 mm thickness, skin layer removed product) and beaded polystyrene foam (JIS A9511 EPS1-4). Product, 30-80 mm thick, skin layer removed product).

Moreover, in the manufacturing method shown in FIG. 3, as a heat insulating material, three types of JIS A9511 XPSs having a thickness of 30 mm (product name: Eslenfoam SU (manufactured by Sekisui Plastics Co., Ltd.)) are used, and a pressure roll The roll clearance of 61, 62 is set to the thickness of the heat insulating material (30 mm), and an alkali-resistant glass fiber mesh (a woven product) (product name: GFN-1 (manufactured by Tralmax Co., Ltd.)) is used as the netting material. As the pressure-sensitive adhesive, an acrylic copolymer aqueous emulsion (coating amount: 24 g / m ² ) (product name: Sdyne # 7110 (manufactured by Sekisui Fuller Co., Ltd.)) can be used to manufacture a heat insulating panel. The pressure at the time of adhering the netting material to the heat insulating material by widening and narrowing the roll clearance of the pressure rolls 61 and 62 with respect to the thickness of the heat insulating material. The peel strength of the mesh material with respect to the heat insulating material can be adjusted to an appropriate value.In the following peel test, a heat insulating panel is manufactured from the heat insulating material, adhesive, and net material having the above specifications, and the heat insulating material. A plurality of heat insulation panel examples were manufactured and tested by changing the pressure at the time of adhering the mesh material.

[Peel test and results]
Below, the method and test result are demonstrated about the implemented peeling test. The heat insulation panel used for the test is manufactured from the heat insulation material (thickness of 30 mm), the adhesive, and the net material having the above specifications, and the heat insulation panel produced when the roll clearance is 31.5 mm is defined as Example 1, and the roll A heat insulating panel manufactured when the clearance is 30 mm is referred to as Example 2, a heat insulating panel manufactured when the roll clearance is 29 mm is referred to as Example 3, and a heat insulating panel manufactured when the roll clearance is 28 mm is described as the Example. 4 Further, as a comparative example, a heat insulating panel manufactured using a heat insulating material, a pressure-sensitive adhesive, and a net material having the same specifications as those of the example and having a roll clearance of 32.5 mm is referred to as a comparative example 1. In addition, a heat insulating material and a net material are firmly bonded with a vinyl acetate emulsion-based adhesive (application amount: 24 g / m ² ) (product name: R194 (manufactured by Cemedine Co., Ltd.), and the roll clearance is set to 31.5 mm. The heat insulating panel manufactured in this way is referred to as Comparative Example 2, and the heat insulating panel manufactured with the roll clearance set to 29 mm is referred to as Comparative Example 3.

  The peel test method uses a tension universal testing machine UCT-10T (manufactured by Orientec Co., Ltd.), and the mesh material is 90 degrees with respect to the heat insulating material to which a 20 mm wide and 200 mm long mesh material is adhered or bonded. The peel strength when peeled in the direction at a speed of 100 mm / min was calculated by the following equation, and the results are shown in Table 1.

[Equation 1]
Peel strength (gf / 20 mm width) = maximum point load (gf) / test specimen width (20 mm)

  In Table 1, the initial peel strength is the peel strength when the heat insulating material and the net material are first attached with a predetermined roll clearance. The re-adhesion peel strength is the peel strength when the heat insulating material and the net material are re-adhered with the same predetermined roll clearance after peeling.

  In Table 1, the pass / fail of workability is determined to be negative when it is determined that it is difficult to work because it is difficult for five or more of the ten workers to peel off the net material or the net material does not re-adhere. This is based on a sensory test. As is clear from Table 1, in Comparative Example 1 having an initial peel strength of 20 gf / 20 mm width, re-adhesion becomes extremely difficult and the purpose of the heat insulating panel of the present invention cannot be achieved. On the other hand, unlike Examples 1 to 4, in Comparative Examples 2 and 3 in which the heat insulating material and the net material were bonded with an adhesive having a strong adhesive strength, the initial peel strength was 812 gf / 20 mm width exceeding 750 gf / 20 mm width, 992 gf / 20 mm width, and in this case, the workability deteriorated. Moreover, the heat insulating material caused material destruction, and re-adhesion was extremely difficult.

  In Examples 1-4, the net material in a good adhesive state peels without causing the member destruction of the heat insulating material, and maintains a peel strength that causes no problem even during re-adhesion.

  As a result of the above peeling test, it can be concluded that the adhesive strength (peeling strength) between the heat insulating material and the netting material is preferably in the range of 20 to 750 gf / 20 mm width.

  The embodiment of the present invention has been described in detail with reference to the drawings. However, the specific configuration is not limited to this embodiment, and there are design changes and the like without departing from the gist of the present invention. They are also included in the present invention.
