FR2743586A1 - Insulated sheet metal cover - Google Patents

Abstract

The sheet metal cover is constituted from modules composed of pre-lacquered galvanised steel parts (1) incorporating a rigid polyurethane foam insulation. These modules are fixed on rafters (14) by fixing legs (2) which provide an under roof ventilation. The modules are fitted by sliding in clamps (13). Sealed junction parts are assured by an elastomer string-course on pre-formed grooves.

Description

DESCRIPTION
The present invention relates to a new covering process in the field of
Building.

 The covers commonly used require battening, counter battening for ventilation under the roof as well as a protective screen for perfect waterproofness.

 These often generate loss of time during implementation, labor during handling. and significant expenses for traditional coverage.

 l, e method according to the invention pennet to remedy these drawbacks. It is made up of elements in prepainted galvanized steel sheet comprising clips for interlocking, of waterproofness reported in polyurethane foam underlay. and mounting tabs raising the cover to ensure good ventilation.

In addition, these elements of standard length of 6. O () m facilitate the implementation during installation, and considerably reduce the loss of time during handling.

Otherwise. The whole remains undeformable by the number of supports (6 to 15), and always provides a contemporary aesthetic thanks to its general appearance
According to the embodiments, the cover always preserves these complementary elements as well as its waterproofing linings as for a conventional roof such as: -feaves (4) - arétiers (11) - valleys (17) - ventilation cat flaps (8) -junctions (7 which are made of prepainted galvanized steel.

 For specific points such as stump penetrations, lateral banks or sewer banks, the elements can be shaped using a folder that the roofer has.

The accompanying drawings illustrate the various devices and methods:
Figure I represents the device of a current element:
It is composed of a prepainted galvanized steel sheet (1), of an insulator incorporated in polyurethane foam (3) STYRODUR type (registered trademark (which is glued in manufacturing allowing a waterproofing role. The legs (2) fix on the rafters (14) ensure the maintenance of the element and provide ventilation under the roof.The clips (13) allow the interlocking by sliding of the elements.

Figure 2 shows in section the fixing of the current elements.

 The legs (2) are fixed to the rafters (14) by self-drilling VBA t sis (registered trademark) and fitted onto the clamp (13) of the element downstream.

The clamps (13) ensure sliding interlocking and prevent the ingress of water or powdery snow that may occur. The insulation (3) reinforces the rigidity of the elements and can be easily cut with the cutter blade in order to be able to carry out the necessary assemblies.

Figure 3 shows in section the fixing of the ridge element (4) on the current elements.

 The assembly is carried out by rivets on the clamps (13) of the element (I) downstream.

Figure 4 shows in section the principle in sewer bank.

 The first element (1) and placed on a cleat of hois (said tilting batten) but retained by the clamp (13) of the element upstream. A simple fold (5) made by the roofer allows the water to flow into the gutter.

Figure 5 shows in section the principle on strain penetration.

 A fold (6) is produced on a current element (1) in order to obtain a rise in sealing.

The insulation (3) is cut to the desired length. A flashing strip (15) will complete the watertightness of the assembly.

FIG. 6 represents the device to be used when a longitudinal junction is provided between two elements.

 The part (7) slides under the elements (1) and slides under the clamps (13).

Sealing is ensured by elastomeric cords (9) or silicone on preformed grooves (16) produced during manufacturing.

Figure 7 shows the taxation of a cat door element "(8) allowing air inlets for ventilation under the roof.

 The connections as well as the sealing are carried out in the same manner as above.

 Furthermore, for this type of roofing, service hooks (10) are provided for each provision of cat door element (8): These hooks 810) allow the installation of a ladder or the like in order to be able to circulate on the roof. These are fixed on the rafters (14) and pass through the air inlet opening of the room (8).

FIG. 8 shows an element of hipbones (11).

 The assembly is done by interlocking the clamps (13) of the hip element (11) on the clamps (13) of the elements (1) downstream. The fixing will be done by riveting on the current elements (t).

Figure 9 shows the bank principle against a wall.

 The current element (1) is shaped by a fold (12) by the roofer having previously cut the insulation (3) to the desired length.

Claims (4)
