Description

  The present invention relates to a heat insulating roof structure in which a heat insulating plate such as a foamed resin plate is disposed on a roof plate, and a heat insulating plate fixing member and a fixing jig used therefor.

  It is required from the viewpoint of energy saving and the like that the roof has a heat insulating structure. However, it is sufficiently advanced to provide a heat insulating structure in roofs using metal roof plates such as slate plates, deck plates and groove plates, which are often used in factories, warehouses or temporary stores. It's hard to say.

  Patent Documents 1 and 2 propose a roof structure in which a heat insulating plate can be attached on a roof plate relatively easily regardless of whether it is an existing installation. In Patent Document 1, a water retaining plate having heat insulation is laid on a so-called folded plate roof so as to straddle the top of the folded plate, and a press plate formed into a long flat plate shape on the laid water retaining plate. A roof structure is described in which a bar is arranged in parallel to the top of a folded plate, and then the whole is integrally tightened with bolts and nuts extending from the folded plate side. In Patent Document 2, a heat insulating material having a metal skin portion is laid on a metal folded plate constituting a folded plate roof, and a fixing screw is driven from above the heat insulating material toward the folded plate through a washer-shaped fixing bracket. Thus, there is described a heat insulating roof structure in which a heat insulating plate is fixed to a folded plate, and a waterproof sheet is fixed thereon by means such as heat-sealing the back surface to the fixing fitting.

  The heat insulating roof structure described in the patent document can fix the heat insulating plate on the folded plate roof relatively easily, and can be constructed at a low cost. However, in any structure, in order to fix the heat insulating plate to the folded plate, bolts and fixing screws penetrate the heat insulating plate, and the heat insulating plate is easily damaged.

  Moreover, in the thing of patent document 1, it is made to pass the existing volt | bolt standing upright on the folded-plate side through the bolt through-hole previously formed in the heat insulation board, and a heat insulation board is fixed, High accuracy is required for positioning of the bolt through-hole to be formed. If the accuracy is poor, a gap may be generated after laying and the heat insulation performance may be lowered.

  The one described in Patent Document 2 is designed so that a fixed screw is driven from above the laid heat insulating plate, and there is relatively little possibility of a gap between the heat insulating plates. However, to accurately drive a screw at the top of the folded plate, Careful work is required. Moreover, after fixing a heat insulation board, the operation | work which spreads a waterproof sheet on it cannot be said to be easy.

  The present invention has been made in view of the circumstances as described above, and provides a further improved heat insulating roof structure that enables stable installation of a heat insulating plate on a roof plate with simpler construction. The purpose is to do. Moreover, an object of this invention is to provide the heat insulation board fastening member and fixing jig which are used for construction of the heat insulation roof structure.

  The heat insulating roof structure according to the present invention basically includes a long heat insulating plate fastening member having a base plate portion and a receiving portion formed at least on the side opposite to the eaves side on the roof plate in parallel with the eaves edge. It is fixed in multiple stages, and the heat insulating plate is fastened between adjacent heat insulating plate fastening members with one edge inserted into the receiving port.

  In the above heat insulating roof structure, the heat insulating plate is fixed on the roof plate using a long heat insulating plate fixing member fixed to the roof plate, and a through hole is formed in the heat insulating plate. Therefore, damage to the heat insulating plate can be avoided as much as possible. It is also possible to avoid a large gap between the heat insulating plates. Furthermore, the heat insulating plate is fastened in a state where one end edge is inserted into the receiving port portion of the heat insulating plate fastening member, and a stable fastening state can be obtained as it is.

  In the heat insulating roof structure according to the present invention, the material of the heat insulating plate is not particularly limited, but preferably, a foamed resin such as polystyrene, polyethylene, or polypropylene is used. In particular, an extruded polystyrene foam defined in JIS A9511 is preferable, but a foamed resin plate obtained by bead-type foaming may be used. The material of the heat insulating plate fastening member is arbitrary as long as it is a material that does not corrode, and examples thereof include a metal subjected to a rust prevention treatment, a non-ferrous metal, and a resin. Of these, non-ferrous metals such as aluminum are preferable because they are lightweight and easy to process.

  In the heat insulating roof structure according to the present invention, the heat insulating plate fastening member may be directly fixed to the roof plate, or may be fixed to the roof plate through a plurality of fixing jigs fixed to the roof plate. When a fixing jig is used, the same material as the heat insulating plate fastening member can be used as the material of the fixing jig. Since the heat insulating plate fastening member or the fixing jig can be fixed to the roof plate without fixing the heat insulating material, the fixing work is easy.

  In the heat insulating roof structure according to the present invention, the roof plate may be a flat plate shape or a roof plate having a plurality of ridges spaced in a direction orthogonal to the eaves edge. In the latter case, a so-called folded plate roof using a deck plate or the like may be used, or a slate plate such as a corrugated plate may be used. Alternatively, a roof plate having a shape in which a so-called groove plate is used and a cap member is crowned on an adjacent rising portion thereof may be used. In the case of a folded plate roof, the upper surface of all the ridges may be a flat surface, or may have a shape in which a ridge is formed on the upper surface of at least some of the ridges. As will be described later, in the latter case, the heat insulating plate fastening member is preferably fixed to the roof plate via a fixing jig having a side plate that can straddle the standing part.

  In the heat insulating roof structure according to the present invention, a protective layer is preferably formed on the heat insulating plate that is fastened. For the protective layer, a metal plate with excellent corrosion resistance and weather resistance such as a galvanized steel sheet, a waterproof sheet such as a vinyl chloride resin sheet and an asphalt sheet, a covering material made of a polyurethane resin or an acrylic resin, or The thing which laminated | stacked them is mentioned. The protective layer may be laminated and fixed on the heat insulating plate after the heat insulating plate is fastened to the roof plate, and a heat insulating plate in which the protective layer is laminated in advance is used. Lamination may be performed simultaneously.

  When using a heat insulating plate in which protective layers are laminated and integrated, it is recommended to use a layer in which a protective layer having a size that protrudes outward by a predetermined amount from two adjacent sides of the heat insulating plate is used. Thereby, since the butting | matching part of adjacent heat insulation boards can be covered with the part which the protective layer has protruded, the more perfect protective layer without a gap | interval as a whole can be formed. Preferably, a nonwoven fabric is laminated | stacked on the back surface of a heat insulation board. Thereby, the bending strength of the heat insulating plate is improved, and it is possible to effectively avoid the occurrence of cracks in the heat insulating plate when an excessive concentrated load is generated on the upper surface.

  The present invention, as a heat insulating plate fastening member used in the above-described heat insulating roof structure, is a long substrate portion that can be placed on the roof plate, and a longitudinal direction from a substantially central portion in the short direction of the long substrate portion. And a horizontal portion extending substantially parallel to the substrate portion in one or both directions from the upper end of the rising portion. The substrate portion, the rising portion, and the horizontal portion end the heat insulating plate. Also disclosed is a heat insulating plate fastening member in which a receiving portion for receiving the edge is formed.

  In the above heat insulating plate fixing member, in the case of the heat insulating plate fixing member in a form in which the horizontal portion extends only to one side, it is fixed to the upper surface on the side where the horizontal portion of the substrate portion does not extend. It is a preferable form to form protrusions that can enter the back surface of the heat insulating plate at intervals. By having such a protrusion, it is possible to reliably prevent the clamped heat insulating plate from inadvertently moving in the lateral direction, and the fixing mode of the heat insulating plate can be further stabilized. .

  The present invention also provides a fixing jig comprising a clip part for clipping a board part opposite to a receiving part of the heat insulating plate fixing member and a fixing part to the roof plate as a fixing jig used together with the heat insulating plate fixing member. A tool is also disclosed. In addition, the fixing jig used for fixing the heat insulating plate fixing member to the fixing plate of another aspect, in particular, the roof plate having a shape in which a ridge is formed on the upper surface of at least a part of the ridge of the roof plate. As a tool, a clip part that clips the board part on the opposite side of the receptacle part of the heat insulating plate fastening member, left and right side plates that are formed in the lower part of the clip part and surround the standing part, and lower ends of the left and right side plates There is also disclosed a fixing jig provided with a fixing screw portion that is provided and capable of tightening the lower end portion of the standing spring.

  By using such a fixing jig, the operation of fixing the long heat insulating plate fastening member on the roof plate can be performed more easily.

The top part 4 of the strip 2 is a flat plane part 4. On the flat surface portion 4, the heat insulating plate fastening members 10 are fixed in multiple stages so as to straddle the plurality of ridges 2 in a direction parallel to the eaves edge.

  The heat insulating plate fastening member 10 is made by extrusion molding or the like from a metal material such as aluminum or a resin material, and as shown in FIG. A rising portion 12 rising from the central portion over the entire length in the longitudinal direction, and a horizontal portion 13 extending substantially parallel to the substrate portion 11 in one direction from the upper end of the rising portion 12, the substrate portion 11 and the rising portion 12 and the horizontal part 13 form a receiving part 14 for accommodating the edge of the heat insulating plate 20. Further, on the upper surface of the substrate portion 11a on the side of the substrate portion 11 where the horizontal portion 13 does not extend, a projection 15 having a size and a shape that can enter the back surface of the heat insulating plate 20 to be fastened is spaced apart. A plurality are formed. The board portion 11 a is also formed with a fastener opening 16 that is used when the heat insulating plate fastening member 10 is fixed to the convex flat portion 4 of the roof plate 1. Although not shown, the horizontal portion may extend from the upper end of the rising portion 12 in substantially parallel to the substrate portion 11 in both directions. In this case, the receiving portion 14 has the rising portion 12 as a common bottom surface. It is formed on both the left and right as a part. In addition, when using the heat insulating board fixing member of this form, the fixing method of the heat insulating board shown in FIG. 3b mentioned later is employ | adopted.

  The protrusion 15 may be a cut-and-raised piece from the substrate portion 11a, or may be a member that is separately attached by welding or the like. The protrusion 15 preferably has a sharp tip, and the height is equal to or less than the thickness of the heat insulating plate 20 to be fastened, preferably about 1/10 to 1/3 of the thickness. The protrusion 15 may be omitted when the required stability for securing the heat insulating plate 20 is secured. Further, the above-described fastener opening 16 may be omitted when the fixing jig 30 is used as described later.

  The heat insulating plate 20 has a rectangular shape, and is preferably a polystyrene foam. Further, the thickness of the heat insulating plate 20 and the inner height of the receiving port portion 14 formed in the heat insulating plate fastening member 10 are substantially the same.

  In the example shown in FIG. 1, the heat insulating plate fastener 10 is driven by driving an appropriate retaining screw 17 from above into the convex flat portion 4 of the roof plate 1 through the fastener opening 16 formed in the substrate portion 11 a. , Fixed to the roof plate 1.

The required number of heat insulating plates 20 can be fastened on the roof plate 1 by repeating the method of pushing down.

  FIG. 3 b shows another method for fastening the heat insulating plate 20. In this case, one end edge of the heat insulating plate 20 is inserted into the receiving port portion 14 of the heat insulating plate fastener 10 and placed on the ridge flat surface portion 4 of the roof plate 1. And it slides until the other edge side of the inserted heat insulation board 20 hits the heat insulation board fastener 10 which has already been fixed to the roof board 1 with the heat insulation board 20. Since the heat insulating plate fastener 10 is positioned by the impact, it is fixed to the convex flat surface portion 4 of the roof plate 1 using an appropriate stop screw 17 at that position. In addition, it was formed in the board | substrate part part 11a of the heat insulation board fastener 10 by making the state where the edge side slightly floated just before the edge of the heat insulation board 20 contacted the heat insulation board fastener 10, and pushing down after an impact. The protrusion 15 is stably pierced on the back surface side of the heat insulating plate 20.

  FIG. 4 shows a mode in which the heat insulating plate fastener 10 is fixed to the ridge plane portion 4 of the roof plate 1 by using a fixing jig 30. The fixing jig 30 preferably has a width that is slightly narrower than the lateral width of the ridge plane portion 4, and is opposite to the receiving portion 14 of the heat insulating plate fastening member 10 to be fixed on the roof plate 1. The clip portion 31 that is elastically clipped with the substrate portion 11a inserted therein and the fixing portion 32 to the ridge plane portion 4 of the roof plate 1 are configured.

  When fixing, as shown in FIG. 4, the insulating plate fixing member 10 is positioned in the same manner as described above with the substrate portion 11 a of the insulating plate fixing member 10 inserted into the clip portion 31. After the positioning, an appropriate set screw 17 is driven from the fixing portion 32 and fixed to the convex flat surface portion 4 of the roof plate 1. The fixing jig 30 does not have to be fixed to all the ridge plane portions 4, but at least to the two ridge plane portions 4 located in the vicinity of both ends of the heat insulating plate fastening member 10. It is sufficient if it is fixed.

  The example shown in FIG. 5 shows an example in which a so-called groove plate 6 having rising pieces on both sides is used as the roof plate 1. A support base 8 (may be a laminate of a heat insulating material and a moisture proof material) is arranged on an appropriate main building 7, and a groove plate 6 is fixed on the support base 8 at a predetermined interval. . A cap 9 is fixed to a connecting portion between adjacent groove plates 6, and a heat insulating plate fixing member 10 is fixed to the cap 9 in the same manner as described above, and a heat insulating material 20 is fixed. It is done.
