When the worker gets on top during construction, temporarily places construction equipment, materials, tools, etc., when bent, by overlapping the bent part of the base and laminating the heat insulating material, By overlapping and not laminating the heat insulating material, it will be bent from the end of the laminated heat insulating material when the worker on the construction rides up or temporarily places construction equipment, materials, tools, etc. It is possible to prevent the start of peeling from the laminated end portion of the laminated heat insulating material due to the above. And the heat insulation effect of a thin-plate roof member can be maintained more fully with durability over time. By overlapping the bent portion of the thin roof member with a laminated heat insulating material, the surface defect that tends to occur on the stressed surface layer and its expansion are protected from the external environment after the bending portion of the thin roof member is bent. There are effects.

  According to the present invention, when processing such as molding of the thin plate roof member in a factory is increased, the product of the thin plate roof member depending on the degree to which the product of the thin plate roof member and the semi-finished product are bent. The semi-finished product itself becomes three-dimensional. As a result, the volume is increased throughout. In addition, it is necessary to manufacture a material handling container and jig dedicated to transportation so that the bent part will not be deformed by the weight of material overlap or vibration during transportation. Goes up. In the present invention, these costs can be reduced, and quality deterioration of the products and semi-finished products of the thin folded plate roof member during transportation can be avoided. In the vicinity of the construction site of the thin plate folded plate roof member, if the thin plate folded plate roof member is processed in many cases, the transportation cost of the thin plate folded plate roof member and the semi-finished product and the material handling container and jig dedicated to transportation Manufacturing costs can be greatly reduced. Even in remote locations, it can be assembled and installed with a low total cost.

  FIG. 4 is a schematic vertical sectional view with respect to the length direction of the thin plate roof member of the embodiment in which a heat insulating material is laminated on the thin plate roof member of the present invention. In FIG. 4, the same reference numerals used are the same as those in FIGS. 1, 2, and 3. The heat insulating material T was laminated | stacked on the thin-plate roof member of embodiment of this invention.

  In the embodiment in which a heat insulating material is laminated on the thin folded plate roof member of the present invention, a polyethylene foam having a thickness of 2 mm is laminated as the heat insulating material T. As the polyethylene foam, a commercially available foam obtained by foaming and crosslinking using polyethylene resin (LDPE, EVA) as a base material is suitable for laminating as a heat insulating material for a roof. Originally produced in block form, but undergoes processing such as slicing, cutting, sticking, fusing, punching, bonding, hot pressing, etc., and it is difficult to induce condensation even under the heat cycle of a thin metal roof, as a roof Composite laminate and function as a thin roof composite laminate with good waterproof properties.

  There are two types of polyethylene foam to be laminated on the heat insulating material T: a closed cell type that does not allow water and air to pass, and an open cell type that allows water and air to pass. The type is preferred. The closed-cell polyethylene foam is laminated on a metal sheet thin plate roof member, and the air bubbles are fine, flexible, restorative, excellent shock-absorbing, thermal insulation, levitation, weather resistance, and chemical resistance. In addition to its high effect, when a construction worker, riding on construction equipment, or temporarily placing construction equipment, materials, tools, etc., the thin folded plate roof member is subject to elasticity when subjected to vertical or horizontal stress due to gravity or other factors.

Absent.

  Furthermore, in the embodiment of the present invention, when assembling the thin roof members to be engaged with each other, two substantially downward right angles projecting from the substantially U-shaped portion of the thin folded plate roof member or the eaves arabesque member due to operational variations are formed. Any part in the vicinity of the L-shaped section in cross-section, and the substantially U-shaped section of the thin folded plate roof member or the two L-shaped sections that are substantially perpendicular to the bottom and project from the arabesque member below the eaves, and other specific parts Touches the surface of the main body material of the coating film, clad material, surface treatment film, or thin folded plate roof member, and some scratches or rubbing marks are created. The effect of minimizing the progress of corrosion and stress corrosion is exhibited.

  In recent years, a large earthquake in Japan has caused heavy Japanese tiles to collapse and partially collapse houses and buildings that are not fully earthquake-resistant. There are concerns about such damage even in earthquakes that are expected to occur in the future. Heavy roofs, such as slate roofs, place a heavy burden on houses and buildings in the event of a major earthquake. Here, avoiding these, providing a durable and long maintenance span, for example, consisting of a thin metal plate, lightweight and strong, and a highly waterproof thin plate folded plate roof member and its assembly method, Industrial applicability is great.
