NL8203546A - Roof rafter construction for building - has boards in grooves of facing sides and foam plates between these sides and fixed on boards - Google Patents

Abstract

The roof structure comprises parallel rafters (2,3) extending from the ridge to the eaves. Boards (7) which are secured between the rafters carry foam material (8), covering the widths between adjacent rafters. The boards are wider and their laterally projecting edges engage corresponding grooves (9,10) in the side faces of the rafters.

Description

NO 31341

Roof construction for a structure.

The invention relates to a roof construction for a building structure, such as a house, at least consisting of a ridge rail, a gutter rail and a plurality of tracks running parallel to each other and at a distance from each other between ridge rail and gutter rail and further comprising 5 between the tracks placed plates, on which there is a foam layer, the width of which corresponds to the distance between the mutually facing surfaces of the tracks.

Such a hood construction is known and use is made here of cross-section T-shaped tracks, which are composed of glued parts. The foamed plates are placed and fixed on the protruding edges or flanges of the tracks during the production of the hood after the placing of the tracks. The production of such traces is laborious and therefore expensive.

The tracks must have such a strength that the roof load 15 can be absorbed by the protruding edges or flanges.

The object of the invention is to provide a hood construction which is particularly simple to manufacture.

This object is achieved according to the invention in that at least the tracks on both sides are provided in their vertical planes with a groove, the width of the thickness of the plates and the plates protrude outside the foam material with edges whose width corresponds to the depth of the grooves.

The beams from which the tracks are made must, like all other beams that make up the hood construction, such as ridge and guttering, be subjected to a planing operation beforehand in order to obtain the correct size and a smooth surface. The grooves to be provided at least in the tracks according to the invention can be made at the same time as the planing and require no additional processing, while yet a sufficiently strong fastening construction can be obtained for receiving the plates.

In addition to the tracks, these grooves can also be provided in the rails and in beams located at the location of roof openings.

With the hood construction according to the invention it is no longer It is necessary to use glue or nail joints for fixing the foamed plates because the plates are completely enclosed in the grooves. The distance between the rails is guaranteed by its own stiffness, the attachment of the rails to the ridge rail,

The invention therefore provides a very simple solution for assembling the hood construction, since no additional processing is required to make the grooves and the mounting can take place very quickly by sliding the plates with the edges into the grooves and a line or by placing one plate with its edge in an assembled rail each time and then applying the adjacent rail; This means that the method of manufacturing the hood 10 is different than usual. The normal way of thinking in the construction of a hood is that one first attaches all tracks and then installs the roof plates. This explains why the known hood construction uses T-shaped tracks.

The invention will now be further elucidated with reference to the drawings.

Fig. 1 shows in perspective a part of a hood construction according to the invention.

Fig. 2 shows a section of the hood construction in section.

Fig. 1 shows a ridge rule 1, tracks 2, 3 and 4 and trimming bars 5, 6, respectively.

Plates are placed between the tracks, such as, for example, plate 7, with a foam plate 8 thereon. All tracks are provided on both sides with grooves 9 and 10 respectively.

Fig. 1 shows the parts in disassembled condition and thereby shows that, if desired, the trimming beams, such as 6, can also be provided with a groove 11.

Fig. 2 shows tracks 2 and 3 in cross section provided with the grooves 9 and 10 and with plates 7 with foam 8 incorporated in the grooves.

"When planing the beams that should form tracks 2 and 3,! 30, the groove 9 and 10 can be provided at the same time, so that without additional processing, tracks are created which the plates can take up and carry. The plates then naturally have an adapted width and thus protrude with an edge outside the foam layer 8.
