Description

[Detailed description of the invention] (Technical field) The invention relates to an eave closure structure for an insulating roofing material in which a synthetic resin insulation material is filled between the front and back metal plates. It relates to technology that attempts to improve workability while ensuring that there are no obstructions.

(Background technology) Conventionally, in the case of insulating roofing materials in which insulation material made of foamed synthetic resin such as urethane resin is filled between the front and back metal plates, when this insulating roofing material is installed, the insulation material is not applied to the eaves side. The end faces of the insulation material are exposed, and the end faces of the insulation material are hidden and stored, but insulation materials made of foamed synthetic resin such as urethane resin have self-adhesive properties when foam-molded between the front and back metal plates, and the front and back sides are bonded together. Because it is firmly adhered to the metal plate of the insulation material, it is difficult to insert an arabesque-like eave binding material between the metal plate and the insulation material, and this poses the problem of requiring time and effort to install the eave binding material. Ta. In order to solve this problem, it may be possible to attach an eave-edge binding material 5' having a U-shaped cross section to the end of the eave-side of the insulating roofing material 3', as shown in Fig. 10. In this configuration, in which the eave end material 5' having a U-shaped cross section is held by the insulating roofing material 3', the U-shaped upper piece 9' overlaps the metal plate 1' on the surface, and the upper piece 9' There was a problem in that the upper piece 9' protruded from the metal plate 1' and obstructed the drainage of rainwater and snowfall.

(Purpose of the invention) The present invention was devised in view of the above-mentioned problems, and its purpose is to easily and easily connect a metal plate and a resin heat insulating material with a rational device. An object of the present invention is to provide an eaves closing structure for an insulating roofing material that can be inserted and does not impede drainage of rainwater or falling snow, and can improve the workability of the eaves closing material. .

(Disclosure of the invention) The present invention provides a resin heat insulating material 2 such as a foamed synthetic resin between a metal plate 1 on the front side and a metal plate 1 on the back side.
is provided, and the resin insulating material 2 is adhered to both metal plates 1, 1 over substantially the entire surface thereof, respectively, to close the eaves of the insulating roofing material 3. In this case, the tip of the metal plate on the front side on the eaves side protrudes further toward the eaves than the resin insulation material and the metal plate on the back side, and the metal plate 1 on the front side and the resin insulation material 2
A release paper 4 is interposed between the metal plate 1 and the resin heat insulating material 2. This relates to an eaves closing structure of an insulating roofing material in which a connecting piece 6 is inserted and connected, and the exposed end surface 7 on the eaves side of the resin heat insulating material 2 is covered with a covering piece 8 of the eaves closing material 5, and is configured in this way. As a result, we were able to achieve the above objectives.

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

The heat insulating roofing material 3 is a material in which a resin heat insulating material 2 made of hard foamed synthetic resin such as urethane resin is filled between the front and back metal plates 1 and 1, and as shown in FIG. and the lower forming conveyor 11, the front side metal plate 1 and the back side metal plate 1

An unfoamed resin material 12 such as urethane resin between 1 and 1
is supplied, and the unfoamed resin material 12 is foam-molded between both metal plates 1, 1 to form a long original roofing material plate 13.
The intermediate product 14 of the heat insulating roof material 3 is obtained by continuously producing the heat insulating roof material 3 and then cutting it into a certain length. In such a case, the metal plate 1 on the front side is formed with peaks 15 and valleys 16 long in the feeding direction by the forming roll device 26 during its feeding, and in this way,
A resin heat insulating material 2 is foam-molded between a metal plate 1 on the front side having peaks 15 and troughs 16 and a flat metal plate 1 on the back side.

A release paper 17 as a release material 4 is pasted on the back side of the metal plate 1 on the front side at a pitch corresponding to the length of the insulating roofing material 3. The heat insulating material 2 is designed to be easily peelable.

The roof material base plate 13 continuously produced in this way is cut at the release paper 17 to obtain an intermediate product 14 as shown in FIG. Next, the metal plate 1 on the back side of the intermediate product 14 is cut at a width l ₂ smaller than the width l ₁ of the release paper 17 with a cutting device (not shown) such as a rotary saw tooth, and the metal plate 1 on the back side A cut 18 is made in the resin insulation material 2 near the metal plate 1, and by inserting a cutting tool such as a knife into the cut 18, the metal plate on the back side is cut at the position shown by the imaginary line in FIG. The resin heat insulating material 2 is cut together with the resin heat insulating material 2 so that it can be separated from the other resin heat insulating materials 2. As shown in FIG. 4, the metal plate 1 on the front side of the insulating roofing material 3 protrudes further toward the eaves than the exposed end surface 7 of the resin insulating material 2 on the eaves side. Configure.
In such a heat insulating roofing material 3, the release paper 17 remains at the edge of the eaves so that the resin heat insulating material 2 can be easily peeled off from the metal plate 1 on the front side. be.

FIGS. 6 to 8 show the eaves lining material 5, which is formed by bending a thin metal plate. This eaves finishing material 5
The cover piece 8 has a shape substantially equal to the shape of the exposed end surface 7 on the eaves side of the resin heat insulating material 2 when viewed from the front as shown in FIG. Furthermore, a gripping piece 19 is bent at the lower edge of the cover piece 8 so as to face obliquely upward at the back.

However, as shown in Fig. 1, the eaves finishing material 5
The connecting piece 6 is inserted between the metal plate 1 on the front side and the resin heat insulating material 2, and the exposed end face 7 of the resin heat insulating material 2 on the eaves side is covered with the cover piece 8. In this case, a release paper 17 is interposed between the metal plate 1 on the front side and the resin heat insulating material 2, and the connection piece 6 can be easily inserted along the release paper 17. Then, the metal plate 1 and the connecting piece 9 are connected with watertight rivets 20.
It is connected with The rivet 20 is fastened at one location at the peak portion 15 and at two locations at the valley portion 16. In addition, a connecting fitting 21 having an L-shaped cross section is attached to the metal plate 1 on the back side with watertight rivets 20.
A gripping piece 19 is loosely engaged with the vertical piece 22 of 1, and this portion is made watertight by tightening the gripping piece 19 with a tightening tool such as pliers. or,

A connecting part 23 is formed by bending the metal plate 1 on the front side at one end in the width direction of the insulating roofing material 3, and a connected part 24 to which the connecting part 23 can be connected is formed at the other end. It has been formed. Note that the shape and form of such heat insulating roofing material 3 can be changed in various designs.

(Effect of the invention) In summary, the present invention involves interposing a release paper between the metal plate on the surface side and the resin insulation material at the end of the eaves of the roofing material, and pasting the release paper on the metal plate. Therefore, although it is possible to use a highly productive production method of adhering a heat insulating material such as foamed synthetic resin between the two metal plates over almost the entire surface, it is possible to separate the metal plates using release paper. A connecting piece of the eaves binding material can be inserted between the metal plate and the resin insulation material, and in this way the connection piece can be easily inserted between the metal plate and the resin insulation material (specifically, the metal plate and the resin insulation material). (between the release paper and the resin heat insulating material attached to There is no risk of rust occurring from this part if it is damaged, and in this way, in a roofing material in which resin insulation material is firmly bonded between both metal plates, the resin insulation material exposed on the eaves side. It has the advantage that it can be easily installed to cover the exposed end surface of the eaves. Moreover, since the connecting piece is inserted into the lower surface of the metal plate, no protrusion is formed on the metal plate, and rainwater or snow falling on the metal plate surface is not obstructed. In addition, since the release paper is attached to the metal plate, at the eave side edge of the insulating roofing material, the front end of the metal plate on the eave side should be placed closer to the eave than the resin insulation material and the metal plate on the back side. To create the protruding structure, the resin insulation material can be easily peeled off and removed from the front metal plate by using a cutting tool to make cuts in the resin insulation material along with the metal plate on the back side and cutting down to the part of the release paper. Therefore, it is possible to easily obtain a structure in which, at the end of the eaves side of the insulating roof material, the front end of the metal plate on the front side protrudes toward the eaves side beyond the resin insulation material and the metal plate on the back side. It has the advantage of being possible.
