EP1586718A1 - Roof batten forming sheet - Google Patents

Abstract

The plate has two flanges with sides sectioned in direction perpendicular to a line of slope of a roof. The flanges have strips at one end to assemble two batten plates together and to form a rib between the plates. The rib has two series of perforations for allowing ventilation between tiles (6) and the plates and for evacuating unfiltered water at draining side of the roof.

Description

The present invention refers to a slab plate which serves as support for tiles in the roofs of buildings.

STATE OF THE ART

a) Poutres ou ossature porteuse (métalliques ou en bois), sur lesquelles on appuie le charpente de la couverture.

b) Courroies (métalliques ou en bois), qui s'appuient sur les poutres ou l'ossature porteuse en les transmettant le poids des éléments de la couverture.

c) Plaques base (céramiques, de fibrociment, bois, panneaux isolants, mixtes, etc.), qui s'appuient sur les courroies et qui servent comme base aux liteaux.

d) Liteaux, qui sont comme de réglettes qui se placent sur les plaques base et qui servent de guide et d'appuie aux tuiles.

e) Tuiles, dernier élément de la couverture, placées sur les liteaux au moyen de clous, vis, crochets en fil d'acier, pâte de mortier ou simplement appuyées, grâce aux talons que quelques tuiles portent dans sa partie inférieure; généralement, dans ces cas ci, on les cloue, vise ou colle aussi avec de produits de scellement spéciaux.

In the construction of roofs for buildings with a slope greater than 10%, light metal or wood structures made up of the following elements are used more frequently:

a) Beams or load-bearing framework (metal or wooden) on which the framework of the roof is supported.

b) Belts (metal or wood), which rely on the beams or the supporting framework, transmitting the weight of the elements of the cover.

c) Base plates (ceramics, fiber cement, wood, insulating panels, mixed, etc.), which rely on the belts and serve as a base for the battens.

d) Liteaux , which are like strips which are placed on the base plates and which serve as a guide and supports the tiles.

e) Tiles, last element of the cover, placed on the battens by means of nails, screws, hooks made of steel wire, mortar paste or simply supported, thanks to the heels that some tiles carry in its lower part; generally, in these cases, they are nailed, aimed or glued also with special sealants.

OBJECT OF THE INVENTION

The present invention refers to a slab plate which serves as a support for the tiles in the roofs of buildings and replaces the assembly formed by belts, the base plate and the battens of a traditional cover; it is of cold-formed steel sheet, the profiled nerves are arranged in a direction perpendicular to the line of greatest slope of creeping on which it is affirmed.

Nerves also have two sets of perforations: one of them allow ventilation of the underside of the tiles by constituting a self-ventilating cover, the others allow to eliminate the filtered water by possible rupturing of tiles to the sewer bank (sand pit), constituting a double cover.

DESCRIPTION OF THE INVENTION

The present invention for which its application is sought as a European patent, refers to a slab plate which serves as support for the tiles of a cover, constructed of sheet steel or other metal, ribbed, cold-formed, folded or obtained by extrusion; it has wings surs the two longitudinal edges terminated by tongues in the same direction or facing, which together by fitting two contiguous plates, fit perfectly forming resistant nerves that save large lights between the support elements. These nerves created by interlocking a slab plate with the following, presage a linear section, rectangular or trapezoidal, according to the tabs of its wings in the same direction or face.

a) Une première série de perforations effectuées dan les ailes des nerfs permettent le pas de l'air à travers la sous-face de la couverture, dans l'espace situé entre les tuiles et la base des plaques liteaux tout le long de rampant, de la rive d'égout jusqu'a la faítage, en provoquant sa ventilation naturelle, ce pourquoi on devra avoir prévu l'entrée d'air en partie basses sous les tuiles positionnées en sablière et la sortie d'air en partie haute, dans le faítage; de cette façon évitons les condensations dans la sous-face de la couverture et éliminons les humidités qui peuvent être produites par la perméabilité ou fracture des tuiles; en plus, la ventilation permettre favoriser l'isolation thermique de la couverture.

b) Il y a une seconde série de perforations dans la base inférieure des ailes des nerfs qui permettent l'évacuation de l'eau jusqu'a la rive d'égout, en réfléchissant sur la surface imperméable des plaques liteaux successifs, dans le cas que des filtrations se produisent à travers les tuiles par saturation, fracture, excès de pluie, neige, etc.

In the wings that conform each nerve, on which are placed the tiles at the distance of the real pose, to allow the support of the heels that each type of tile possesses, one made two series of perforations by press, punched or shears , which can have different shapes and distribution, and perform the following functions:

a) A first series of perforations carried out in the wings of the nerves allow the passage of the air through the underside of the cover, in the space between the tiles and the base of the slab plates all along the crawling, from the sewer bank to the ridge, causing its natural ventilation, so we must have provided the air inlet at the bottom part under the tiles positioned in sand pit and the air outlet at the top, in the ridge; in this way we avoid condensations in the underside of the roof and eliminate the humidities that can be produced by the permeability or fracture of the tiles; in addition, the ventilation allow to favor the thermal insulation of the cover.

b) There is a second series of perforations in the lower base of the nerve wings which allow the evacuation of the water to the sewer bank, reflecting on the impermeable surface of successive slab plates, in the case that filtrations occur through the tiles by saturation, fracture, excess rain, snow, etc.

Each lameau plate has in the posterior zone of its base, that is to say the one situated on the higher part of the zone of the rampant which it occupies, a longitudinal heel on which rests the plate superior plate following, preventing that l water that reflects from one slab plate to another through the perforations in the wings, enter the building; also this heel can be used to perform the union of the tiles plates supports tiles to the supporting structure by means of nails, drill screws, etc. Finally we have arranged an additional longitudinal fold in the base of each plate slab, that in addition to having a greater rigidity, it can be used in conjunction with the heel of the following plate as a support for suspended elements, insulating plates and false ceilings, and also as an insulating fastener projected from the Inside the slab plates, from insulating fibers or other projected insulating material, which take it are trapped in the cavity formed by bend heel of the next slab plate.

This cover can be built directly on the supporting framework or the beams properly separated from each other, or on a base plate, by placing the slats plates with the profiled nerves in the direction perpendicular to the line of greater slope of the cover , assembling by successively interlocking in longitudinal direction the slats plates, thanks to the conformation of its edges. In the transverse direction, it is better to make the smallest possible number of assemblies, because the profiling admits large longitudinal dimensions of slab plates, only limited by transport requirements, up to 12 m and in some cases a larger dimension. This installation process is carried out from the bottom to the top of the cover ramp, and the situation of the first batteau plate is put into question depending on the size of the tiles to be used and the flight planned for the first line. of tiles on the sewer bank. The subjection of the batteau plates to the support, it can be done by means of nails, drills screws or any other usual system by using for this the heel available to each plate liteau. Once covered the crawling thanks to the interlocking of a plate with the following one proceeds to the installation of the tiles, starting with the bank of sewer, lower part of the crawling, until arriving at the ridge, part upper creeper. Both in the sewer bank and in the ridge, they will have special stop profiles, which allow both the air inlet and the water outlet and reach the appropriate height of the first line of tiles in the roof. sewer bank, as well as the air outlet in ridge.

The cross-sectional dimension of each slab support tile will be adequate for each type of tile that exists in the market, and it is necessary that all the tiles support their heels on the nerves of the slab plates, which is why they will form according to the distances between the supports provided by the manufacturer for each type of tile. The simplest way to place the tiles is to support the heel that the tile has in the corresponding conformal nerve and apply a resilient sealant in several points, which ensures its total immobility. However, this model also makes it possible to place the tiles in any other way than is usual in construction, using the nerves of the slab plates as guides and support.

This layout of the cover, with the special configuration of the slats for the support of the tiles, also allows to isolate the cover as acoustically as thermally by projection of fibers or other materials of the sound lower coast, which until today This represents a great difficulty because, for example, in the case of acoustic or fireproofing of smooth surfaces as profiled plates, the attachment between the insulating material and the plate is very difficult to obtain because detach the insulation for lack of attachment and differences in expansion and to obtain it we must use very expensive methods such as the placement of adhesives, mesh etc. With the configuration given to the slab, the problem is solved because by penetrating the fiber into the slot provided between two successive slab plates forging, its detachment by differences in expansion is practically impossible.

This type of slab can also be placed on crawling blankets that have rigid insulation such as polystyrene, glass wool, rock wool, polyurethane slabs, etc., with the added benefit of protecting the insulation from possible filtrations. of water, filtrations that make it lose a large part of their insulating capacity.

Does not alter the essence of this invention the variation of materials, the way, the size, the arrangement of the perforations and the manner of these the last of which is described in a non-exhaustive way, in being this one sufficient for its reproduction by an expert in the matter.

ADVANTAGES OF THE INVENTION

• Remplace la partie d'une couverture formée par des courroies, plaque de base et liteaux par un seul élément, celui formé par les plaques liteaux.

The advantages of the invention are as follows:

• Replaces the part of a blanket formed by belts, baseplate and battens by a single element, that formed by the slabs.

1. - Economie de matériel:

• Economie poutres ou éléments d'ossature porteuse en pouvant sauver de plus grandes lumières entre des appuis, en raison de la configuration des nerfs, qui peuvent sauver de grandes lumières.
• On élimine complètement les courroies.
• On élimine complètement les liteaux.

2. - Economie en main d'oeuvre.

• On supprime trois phases de la construction de la couverture et en conséquence la main d'oeuvre correspondante s'élimine. Ces phases sont la mise en place de les poutres qui sont supprimes, l'employé dans la mise en place de courroies et l'employé dans la mise en place de liteaux, qui n'existent déjà pas.

3. - Economie en temps: Celui qui supposerait d'effectuer les opérations supprimées.

• Aussi amélioration substantiellement le système de construction des couvertures actuelles, parce qu'il permet la ventilation de l'espace comprise entre les tuiles et la plaque base.
• Il s'agit d'une double couverture, parce qu'il élimine à travers la sablière l'eau qui arrive jusqu'à la plaque liteau en raison d'une éventuelle fracture tuiles ou filtration par le biais d'elles.

This implies the following saving in the constructive process of a cover:

1. - Economics of material:

• Saves beams or load-bearing elements by being able to save bigger lights between supports, because of the configuration of the nerves, which can save big lights.
• The belts are completely eliminated.
• The slats are completely eliminated.

2. - Economy in manpower.

• Three phases of the construction of the cover are suppressed and consequently the corresponding manpower is eliminated. These phases are the implementation of the beams that are removed, the employee in the establishment of belts and the employee in the installation of battens, which do not already exist.

3. - Saving time: The one who supposed to carry out the operations removed.

• Also substantially improves the system of construction of the current covers, because it allows the ventilation of the space between the tiles and the base plate.
• This is a double cover, because it eliminates through the sand pit the water that reaches to the slab plate due to a possible fracture tiles or filtration through them.

BRIEF DESCRIPTION OF THE DRAWINGS

Figure 1.- It shows a cross section of a batten plate supports tile, wherein it is shown the profile of the (1A) and the union system by interlocking between two adjacent battens plates with the tongues of wings oriented in the same direction; it is also possible to appreciate the heel of the slab plate which can be used for fixing the slab to the frame carrying the cover, by drill screws (4) or any other fastening system.
