Description

Detailed Description of the Invention [Industrial applications]

The present invention relates to a joint structure for a heat insulating roof panel that is preferably used for a roof of a hot and humid factory or the like.

[Prior art]

Conventionally, a heat insulating roof panel 4 formed by filling a space between the upper and lower metal plates 1 and 2 with a heat insulating material 3 is laid on a roof support material 18 to form a roof. The inventors of the present invention have already connected the front end portion of the upper metal plate 1 so as to project forward longer than the lower metal plate 2 and the heat insulating material 3 over the entire width in the width direction as shown in FIGS. 7 to 9. The heat insulating roof panel 4 is formed as a piece 5, and the connecting piece 5 of the heat insulating roof panel 4 on the upper side in the eaves direction is overlapped on the rear end of the heat insulating roof panel 4 on the lower side with a fastener 16 such as a bolt. A roof structure has been proposed in which the heat insulating roof panels 4 are joined to each other by fixing them (see Japanese Patent Application Laid-Open No. 57-155460).

[Problems to be Solved by the Invention]

In the conventional case, the heat insulating material 3 is exposed on the side of the heat insulating roof panel 4 at the joint portion. Therefore, in a hot and humid factory or the like, moisture permeates from the side of the heat insulating roof panel 4 to cause internal condensation. Occurs, which deteriorates the heat insulating property and corrodes the metal plates 1 and 2. For this reason, packing may be provided between the side portions of the heat insulating roof panel 4, but this is not sufficient to prevent moisture permeation. The present invention has been made to solve the above problems, the purpose of the purpose is to ensure moisture resistance in the joint, excellent heat insulation, can be suitably adopted in a hot and humid factory, workability It is to provide a joined structure of an insulating roof panel which is excellent in

The present invention will be described below based on embodiments shown in the accompanying drawings. As the metal plates 1 and 2, a colored zinc iron plate, a colored aluminum plate, a colored aluminum zinc alloy plated steel plate, a stainless steel plate, a titanium steel plate or the like is adopted. Between the upper and lower metal plates 1 and 2, a foamable synthetic resin material such as hard urethane foam, isocyanurate foam, or phenol foam mixed with a polyol, an isocyanate, a catalyst, a foaming agent or the like is injected and foamed to form the heat insulating material 3. A filled insulating roof panel 4 is formed. As shown in FIG. 5, the upper metal plate 1 has a plurality of peaks 9 formed in the longitudinal direction on the surface of a heat insulating roof panel 4 which is bent into a heat insulating corrugated form, and the metal plate 1 is formed on one side. A side edge is extended to form a covering piece 10, and a locking step portion 11 is formed on the inner side surface of the mountain portion 9 on the other side.
Further, the lower metal plate 2 is bent to form an insertion concave portion 12 and an insertion convex portion 13 at the lower portions of both sides of the heat insulating panel 4, respectively. A packing 14 is attached to the end surface of the other side of the heat insulating roof panel 4. At one end of the heat insulating panel 4 in the longitudinal direction, the lower metal plate 2 is cut together with the heat insulating material 3 for a predetermined length, and a connecting piece 5 formed of an end of the upper metal plate 2 is extended. Thus, a plurality of heat-insulating roof panels 4 are laid on the roof support member 18 which is a steel-made purlin with the longitudinal direction parallel to the eaves direction. In the joint A of the heat insulating roof panels 4 in the eaves direction, the connecting piece 5 of the upper heat insulating roof panel 4a is attached to the end of the lower heat insulating roof panel 4b at the end of the EPT packing 20 as shown in FIGS. 1 and 2. A fixture 16 such as a tex which is covered with a non-moisture-permeable tape 17 which is a butyl tape is adhered to the roof support member 18 which is bridged between the climbing furring strips 19 from the connecting piece 5. It is fixed. The joint A between the heat insulating roof panels 4 is located between the roof support members 18, and the closing plate 6 is arranged below the joint A. The closing plate 6 is composed of a long plate-like body, and a recess 7 having a triangular cross section is formed in the central portion along the longitudinal direction. As shown in FIG. 1 and FIG. It is placed on the roof support material 18 and sandwiched with the moisture impermeable tape 17 so as to be in close contact with the lower surface of the heat insulating roof panel 4, and the recess 7 has the joint portion A
