Description

  The present invention relates to a waterproof structure applicable to a sloped roof, and more particularly to the technical field of a structure in which a flat portion is inclined in one direction.

  Conventionally, as a sloped roof, a folded-plate roof or a slate roof constructed by laying and arranging metal sheets in a corrugated sheet shape is known (see, for example, Patent Documents 1 and 2).

  In Patent Document 1, a plate-like heat insulating member is laid on a waterproof base forming a metal roof such as a folded plate roof, a fixing disk is disposed on the heat insulating member, and a fixing screw is used. The fixing disc is fixed to the waterproof base. A hot melt adhesive layer is provided on the upper surface of the fixing disk. A waterproof sheet made of synthetic resin is laid on the heat insulating member and the fixing disc, and the waterproof sheet is adhered and fixed to the hot melt adhesive layer of the fixing disc.

  In Patent Document 2, a plurality of heat insulating panels in which a heat insulating material is interposed between metal shells are juxtaposed so as to be adjacent to each other, and a waterproof sheet is laid on these heat insulating panels. A resin layer is formed on the metal shell. The waterproof sheet is heat-sealed to the resin layer of the metal shell.

  By the way, since the fixing method using the fixing screw of patent document 1 is a mechanical fixing method, it is called a mechanical fixing method. In the case of this mechanical fixing method, since a plurality of fixing disks are arranged at a predetermined interval, it is inevitable that the portion between the fixing disks in the waterproof sheet will be in a non-fixed state.

  Assuming such a mechanical fixing method, for example, assuming a strong wind such as a typhoon, a flexible sheet such as vinyl chloride is generally used as a waterproof sheet. Therefore, when the wind blows on the waterproof sheet, the portion between the fixing discs in the waterproof sheet is deformed so as to be lifted from the reinforcing material. When the tarpaulin deforms so as to be lifted from the reinforcing material, a force in an obliquely upward direction is applied to the fixing disc. The force applied to the fixing disk acts on the fixing screw, and a diagonally upward force is similarly applied to the fixing screw.

  After completion by the mechanical fixing method, at first, the restraining force by the fixing screw and the fixing disc is superior to the force by the wind, but many years have passed since the completion of the construction When the roof material is made of a relatively thin plate material such as a deck plate or a folded plate, for example, when the force by the strong wind is repeatedly applied, the roof material is made by the component force in the vertical direction among diagonal forces acting repeatedly. It may be deformed upward, and the tightening force of the fixing screw may be reduced.

  When the tightening force of the fixing screw decreases, the heat insulating material and the reinforcing material move in the horizontal direction due to the horizontal component force among the repeated diagonal forces, and the head of the fixing screw is also horizontal. It is possible to move in the direction. Since the horizontal movement of the head of the fixing screw acts on the screwing portion to the roofing material, the roofing material of the screwing portion is deformed, whereby the fixing screw is screwed. The diameter of the hole is increased. When the diameter of the hole in which the fixing screw is screwed is increased, the restraining force of the fixing screw is greatly reduced, and as a result, the fixing screw is removed, and the waterproof sheet can not be restrained to the roof material. Performance can not be maintained.

  Further, in Patent Document 2, the waterproof sheet is fixed to the metal shell of the heat insulating panel by heat fusion, and the heat insulating panel is fixed to the waterproof base with a plurality of screws. Therefore, the fixing disk of Patent Document 1 is used There is an advantage that local concentration of load hardly occurs as in the case of

  However, since the upper and lower surfaces of the heat insulating material are covered with the metal outer skin, and the upper metal outer skin and the lower metal outer skin are bonded to the heat insulating material at the peripheral portion, the number of members constituting the heat insulating panel increases. At the same time, the manufacturing process becomes complicated, resulting in high cost.

  The present invention has been made in view of the above point, and an object of the present invention is to maintain waterproof performance at low cost and over a long period of time.

  In order to achieve the above object, according to the present invention, the heat insulating panel is provided such that the metal shell is provided on the upper surface of the heat insulating material while the metal shell is not provided on the lower surface. Fastening or adhesive fixing was used to bond the waterproof sheet to the metal shell.

  According to a first aspect of the present invention, in the waterproof structure of the sloped roof where the flat portion is inclined in one direction, a plurality of sheets are juxtaposed so as to be adjacent to each other on the waterproof foundation of the above-mentioned sloped roof. The heat insulating panel includes a heat insulating panel to be fastened or fixed by adhesion, and a synthetic resin waterproof sheet laid on the upper surface of the heat insulating panel, and the heat insulating panel includes a heat insulating material and a base material bonded to the upper surface of the heat insulating material. A metal plate and a metal shell having a resin covering material for covering the upper surface of the base metal plate, and the lower surface of the heat insulation panel is configured to expose the heat insulating material, and the lower surface of the waterproof sheet is It is characterized in that it is joined to the metal shell.

  According to this configuration, a plurality of heat insulating panels are juxtaposed to be adjacent to each other on the waterproof base, and after fastening and fixing or adhesively fixing a plurality of locations of each heat insulating panel to the waterproof base, a waterproof sheet is laid and the heat insulating panel is installed. Bonding to the metal shell of the roof provides a waterproof structure of the sloped roof. The roof with the ceiling indoors can be easily fastened and fixed, but with the roof without the ceiling indoors, there is a risk that metal scraps produced when screwing in the screws (fastening members) may scatter indoors when fastening and fixing. Adhesive fixing is desirable because

  For example, assuming that a strong wind blows, a force acting to float on the waterproof sheet acts, but this force causes a plurality of fastening portions or adhesive fixing of the heat insulation panel through the joint portion of the heat insulation panel with the metal shell. Since the load is transmitted to the portions, the load is distributed to and acts on the plurality of fastening portions, and the load applied to each fastening portion, in particular, the load in the horizontal direction is reduced. Therefore, waterproof performance is maintained over a long period of time.

  Moreover, since the heat insulating panel is exposed to the heat insulating material from its lower surface and there is no metal shell on the lower surface, the number of members is reduced as compared with the case where metal shells are provided above and below as in Patent Document 2 Become simple.

  A second invention according to the first invention is characterized in that the heat insulating material is formed in a rectangular shape, and at least one side of the heat insulating material is formed to project from the edge of the metal shell. Do.

  According to this configuration, at least one side of the heat insulating material projects from the edge of the metal shell, so that the metal shells of the heat insulating panels adjacent to each other in the juxtaposed state do not interfere with each other, for example, by thermal expansion. it can.

  A third invention according to the second invention is characterized in that the two continuous sides of the heat insulating material are formed to project from the edge of the metal shell.

  According to this configuration, since the two consecutive sides of the heat insulating material project from the edge of the metal shell, the metal shells of the heat insulating panels adjacent in two directions in the juxtaposed state do not interfere with each other, for example, by thermal expansion. Can be

  According to a fourth aspect of the present invention, in the second or third aspect, the upper surface of the portion of the heat insulating material of the heat insulating panel which protrudes from the edge of the metal shell and the upper surface of the metal shell are coplanar. It is characterized in that it is formed in

  According to this configuration, since there is no difference in level between the metal sheath and the portion of the heat insulating material that protrudes from the metal sheath, when the waterproof sheet is laid, it becomes difficult to make a dent on the waterproof sheet.

  A fifth invention according to any one of the first to third inventions is characterized in that the end of the heat insulation panel is formed with a recess or a projection fitted to the other adjacent heat insulation panel. I assume.

  According to this configuration, the heat insulation panels adjacent to each other can be fitted and integrated.

  According to a sixth invention, in any one of the first to fifth inventions, the heat insulating material of the heat insulating panel is made of isocyanurate foam or foamed polyethylene.

  According to this configuration, it is possible to reduce the weight of the heat insulating material having high heat insulating performance.

  A seventh invention is characterized in that, in any one of the first to sixth inventions, the waterproof sheet and the covering material are made of a soft vinyl chloride resin or a polyolefin resin.

  According to this configuration, the waterproof sheet and the covering material can be firmly joined.

  According to the present invention, the heat insulating panel is provided such that the metal shell is provided on the upper surface of the heat insulating material and the metal shell is not provided on the lower surface, and the heat insulating panel is fastened or fixed in plural places to the waterproof base. Since the waterproof sheet is joined to the metal shell, it is possible to obtain a waterproof structure capable of maintaining waterproof performance at low cost and over a long period of time.

  Hereinafter, embodiments of the present invention will be described in detail based on the drawings. The following description of the preferred embodiments is merely illustrative in nature, and is not intended to limit the present invention, its applications, or its applications.

(Embodiment 1)
FIG. 1 is a cross-sectional view of a roof 1 to which a waterproof structure according to a first embodiment of the present invention is applied. The first embodiment is a waterproof structure applied when the building is a new building. The roof 1 includes a synthetic slab deck plate 10, a heat insulating material 11, a heat insulating panel 12, a fixing disk 13, a fixing screw 14, and a waterproof sheet 15. The roof 1 is a sloped roof whose flat portion is inclined in one direction. The direction of the gradient can be set arbitrarily. In addition, although the cross section of each member is shown in FIG. 1, it becomes a cross section of a mutually different site | part.

  The synthetic slab deck plate 10 is formed, for example, by bending a metal plate having a thickness of about 1.2 mm. A waterproof foundation is configured by the synthetic slab deck plate 10.

  The heat insulating material 11 is formed of a plate-like member which is conventionally known, and a plurality of the heat insulating materials 11 are arranged in parallel on the upper surface of the deck plate 10 so as to be adjacent to each other. Although the heat insulating material 11 can be omitted, when the heat insulating material 11 is provided, the heat insulating material 11 can also be part of the waterproof base.

  A plurality of heat insulating panels 12 are juxtaposed so as to be adjacent to each other on the heat insulating material 11. The structure of each heat insulation panel 12 may be the same, but the outer shape may be changed. As shown in FIG. 4, the heat insulation panel 12 has a substantially rectangular shape, and its outer shape may be rectangular or square. Although the thickness of the heat insulation panel 12 is not specifically limited, For example, 5 mm or more and 50 mm or less can be set. Moreover, the width | variety and length of the heat insulation panel 12 can be set to the arbitrary dimension of several dozen cm or more.

  The heat insulating panel 12 includes a heat insulating material 12 a and a metal shell 12 b. The heat insulating material 12a is made of a resin foam. Examples of the resin foam include extruded polystyrene foam (XPS), bead polystyrene foam (EPS), phenol foam, rigid polyurethane foam, expanded polyethylene and the like. When the heat insulation panel 12 is fastened and fixed to a waterproof base, a rigid polyurethane foam having high weather resistance and heat resistance is preferable, and further, a so-called polyisocyanurate foam containing an isocyanurate ring having high flame retardancy is preferable. In the case of bonding and fixing the heat insulation panel, foamed polyethylene having a relatively low hardness is preferable among the heat insulating materials in order to absorb the unevenness of the substrate.

  The outer shape of the heat insulating material 12 a is the same as the outer shape of the heat insulating panel 12, and is therefore substantially rectangular. That is, as shown in FIG. 4, the four sides (the first side A1, the second side A2, the third side A3, the fourth side A4) constituting the edge of the heat insulating material 12a extend linearly. And two consecutive sides (first side A1 and second side A2, second side A2 and third side A3, third side A3 and fourth side A4, fourth side A4 and first side A1) are substantially perpendicular to each other. To meet each other.

  As shown in FIG. 5, the metal shell 12b has a base metal plate 12c adhered to the upper surface of the heat insulating material 12a and a resin covering material 12d for covering the upper surface of the base metal plate 12c. The base metal plate 12c is made of, for example, a steel plate, and the thickness is not particularly limited, but can be set, for example, in the range of 0.5 mm or more and 1.5 mm or less.

  The outer shape of the metal shell 12b is substantially rectangular, and as shown in FIG. 4, the four sides (the first side B1, the second side B2, the third side B3, the third side, and the third side forming the edge of the metal shell 12b) The four sides B4) extend in a straight line, and two consecutive sides (a first side B1 and a second side B2, a second side B2 and a third side B3, a third side B3 and a fourth side B4, a fourth side B4) The four sides B4 and the first side B1) intersect with each other so as to be substantially perpendicular to each other.

  The two continuous sides constituting the edge of the heat insulating material 12a are formed to project horizontally from the edge of the metal shell 12b. That is, the first side A1 and the second side A2 of the heat insulating material 12a are longer than the first side B1 and the second side B2 constituting the edge portion of the metal outer skin 12b, respectively, and the metal outer skin 12b It is located outside of the Further, the first side A1 of the heat insulating material 12a and the first side B1 of the metal shell 12b extend in parallel with each other. The second side A2 of the heat insulating material 12a and the second side B2 of the metal shell 12b also extend in parallel with each other.

  As shown in FIG. 5, although the separation distance L between the first side A1 of the heat insulating material 12a and the first side B1 of the metal shell 12b is not particularly limited, it may be set to, for example, 10 mm or more and 30 mm or less it can. In this embodiment, two continuous sides of the heat insulating material 12a are formed so as to project from the edge of the metal outer skin 12b. However, the present invention is not limited thereto. Only one arbitrary side of the heat insulating material 12a is metal outer skin You may form so that it may protrude from the edge of 12b.

  The covering material 12d can be made of a soft vinyl chloride resin or a polyolefin resin, and is integrated in a state of being adhered to the base metal plate 12c.

  As shown in FIG. 5, the upper surface 12f of the portion of the heat insulating material 12a of the heat insulating panel 12 protruding from the edge of the metal outer skin 12b and the upper surface of the metal outer skin 12b (the upper surface of the cover 12d) are coplanar. It is formed as.

  On the other hand, the metal shell 12 b is not provided on the lower surface of the heat insulation panel 12. Accordingly, since the lower surface of the heat insulating panel 12 is configured to expose the heat insulating material 12 a, the lower surface of the heat insulating material 12 a is in direct contact with the upper surface of the heat insulating material 11 in this embodiment. Since there is no metal shell 12b on the lower surface of the heat insulation panel 12, the structure of the heat insulation panel 12 is simplified and the number of parts can be reduced. In addition, since the heat insulating material 12a made of foam material faces the lower surface of the heat insulating panel 12, the heat insulating material 12a is on the upper surface of the heat insulating material 11 even if, for example, the upper surface of the heat insulating material 11 has some unevenness or step. It deforms along and follows the shape of the upper surface of the heat insulating material 11.

  When molding the heat insulation panel 12, although not shown, a molding apparatus having an upper mold and a lower mold is prepared, the upper mold is opened, and the metal is placed so that the covering material 12d is on the lower mold. Place the hull 12b. Thereafter, the urethane stock solution is filled on the metal shell 12b in the lower mold along the center line in the width direction. At this time, it is preferable to keep the filling point of the urethane stock solution away from the first side B1 and the second side B2 of the metal shell 12b. By doing this, when the upper mold is closed thereafter, curing of the undiluted solution proceeds until the undiluted urethane solution foams and reaches the edge of the metal shell 12b from the filling point, so the undiluted urethane solution goes to the covering 12d side. It becomes difficult to get around. In addition, the shaping | molding method of the heat insulation panel 12 is not restricted to the above-mentioned method, For example, after shape | molding the heat insulation material 12a, the method of adhere | attaching the metal outer skin 12b to the heat insulation material 12a may be used.

  The fixing disk 13 includes a substantially circular steel plate and a resin layer provided on the upper surface of the steel plate. The resin layer can be made of the same material as the covering material 12d. A plurality of fixing disks 13 are used, and the fixing disks 13 are arranged on the upper surface of the heat insulating panel 12 at intervals. The arrangement position of the fixing disk 13 is set such that the convex portion of the synthetic slab deck plate 10 is positioned directly below the fixing disk 13.

  The fixing screw 14 can be configured by, for example, a self drilling screw or the like, and is screwed into the convex shape portion of the synthetic slab deck plate 10 through the fixing disk 13, the heat insulating panel 12 and the heat insulating material 11 from above. . The fixing disc 13 is pressed against the heat insulating panel 12 by screwing the fixing screw 14 into the convex portion of the synthetic slab deck plate 10, and the heat insulating panel 12 with the fixing disc 13 pressed against the heat insulating panel 12 It comes to press against the convex portion of the deck plate 10.

  The waterproof sheet 15 is made of a synthetic resin sheet laid on the upper surface of the heat insulating panel 12. The waterproof sheet 15 can be made of the same material as the covering material 12d, that is, a soft vinyl chloride resin or a polyolefin resin. It is preferable that the waterproof sheet 15, the covering material 12 d, and the resin layer of the fixing disk 13 be made of the same material. A plurality of waterproof sheets 15 can be used. As shown in FIG. 1 and FIG. 2, adjacent waterproof sheets 15 are laid so as to overlap in the thickness direction, and adjacent waterproof sheets 15 are joined to form waterproof sheets 15. Make sure that water does not enter below. Also, the waterproof disc 15 covers the head of the fixing disc 13 and the fixing screw 14. The waterproof sheet 15 and the resin layer of the fixing disk 13 are joined.

  Moreover, the lower surface of the waterproof sheet 15 is joined to the covering material 12d of the metal outer skin 12b, and the lower surface of the waterproof sheet 15 and the covering material 12d of the metal outer skin 12b may be partially joined. You may

  The bonding method between the waterproof sheets 15, the bonding method between the waterproof sheet 15 and the covering material 12 d, and the bonding method between the waterproof sheet 15 and the resin layer of the fixing disc 13 are heat fusion, welding using a solvent, etc. Various welding methods and adhesion methods using conventionally used adhesives can be used.

(Construction method)
Next, the construction method of the waterproof structure comprised as mentioned above is demonstrated. This embodiment has a waterproof structure for new construction, and first, a plurality of heat insulating materials 11 are juxtaposed so as to be adjacent to each other on the deck plate 10 for a synthetic slab.

  Thereafter, a plurality of heat insulation panels 12 are juxtaposed so as to be adjacent to each other on the heat insulation material 11 (see FIG. 4). At this time, the first side A1 of the heat insulating material 12a of the heat insulating panel 12 is disposed in contact with the third side A3 of the heat insulating material 12a of the adjacent heat insulating panel 12. Further, the second side A2 of the heat insulating material 12a of the heat insulating panel 12 is disposed in contact with the fourth side A4 of the heat insulating material 12a of the adjacent heat insulating panel 12. That is, a plurality of heat insulating panels 12 are juxtaposed so that the protruding portion from the edge of the metal shell 12b in the heat insulating material 12a contacts the third side B3 or the fourth side B4 of the metal shell 12b. In the state in which the heat insulation panels 12 are juxtaposed, the upper surface 12 f of the portion of the heat insulating material 12 a protruding from the edge of the metal outer skin 12 b and the upper surface of the metal outer skin 12 b are located on the same plane. (See FIG. 5).

  As in the modification shown in FIG. 6, the end of the heat insulation panel 12 may be formed with a protrusion 12 g or a recess 12 e to be fitted to another adjacent heat insulation panel 12. By fitting the protrusion 12 g of one heat insulation panel 12 to the recess 12 e of the other heat insulation panel 12, the heat insulation panels 12 can be integrated.

  After the heat insulating panels 12 are juxtaposed, a plurality of fixing disks 13 are disposed immediately above the convex portion of the synthetic slab deck plate 10 (see FIG. 2). After disposing the fixing disc 13, the fixing screw 14 is penetrated from above the fixing disc 13 to the fixing disc 13, and is penetrated to the heat insulating panel 12 and the heat insulating material 11. Screw in the convex part. As a result, the heat insulating panel 12 and the heat insulating material 11 are fastened and fixed to the synthetic slab deck plate 10 at a plurality of locations. Further, a plurality of locations of the heat insulating panel 12 may be adhered and fixed to the synthetic slab deck plate 10 with an adhesive.

  After the screwing work of the fixing screw 14 is finished, a plurality of waterproof sheets 15 are laid on the upper surface of the heat insulation panel 12. Then, the waterproof sheets 15 overlapping each other are joined, the waterproof sheet 15 and the covering material 12 d are joined, and the waterproof sheet 15 and the resin layer of the fixing disk 13 are joined.

(Operation and effect of the embodiment)
As explained above, according to this embodiment, a plurality of heat insulation panels 12 are arranged side by side on the synthetic slab deck plate 10 so as to be adjacent to each other, and a plurality of locations of each heat insulation panel 12 are decks for the synthetic slab After fastening and fixing to the plate 10, a waterproof sheet 15 can be laid and joined to the metal shell 12 b of the heat insulating panel 12 to obtain a waterproof structure of the sloped roof.

  For example, assuming that a strong wind blows, a force acting to float on the waterproof sheet 15 acts, but this force causes a plurality of fastenings of the heat insulating panel 12 through the junction of the heat insulating panel 12 with the metal skin 12b. Since the force is transmitted to the part (the fastening part by the fixing screw 14), the load is dispersed and acts on the plurality of fastening parts. Therefore, since the load applied to each fastening portion, in particular, the load in the horizontal direction is reduced, the waterproof performance can be maintained for a long time.

  Moreover, since the heat insulating material 12a is exposed from the lower surface of the heat insulation panel 12 and there is no metal outer skin 12b on the lower surface, the number of members is reduced and the structure is simplified as compared with the case where metal outer skins are provided above and below. The cost can be reduced.

  Further, when the lower surface of the heat insulating material 12 a is in direct contact with the upper surface of the heat insulating material 11, the heat insulating material 12 a deforms along the upper surface of the heat insulating material 11 and follows the shape of the upper surface of the heat insulating material 11. Therefore, even if the upper surface of the heat insulating material 11 has some unevenness or level difference, it does not easily appear on the upper surface of the heat insulating panel 12.

  Furthermore, since the two continuous sides of the heat insulating material 12a project from the edge of the metal outer skin 12b, the metal outer skins 12b of the heat insulating panels 12 adjacent in two directions in a juxtaposed state do not interfere with each other by, for example, thermal expansion. Can be
