AAGAARD ROOF STRUCTURE 2 Sheets-Sheet 2 Filed Sept. 6. 1961 United States Patent M 3,173,224 ROOF STRUCTURE I Georg Christian Schgztnberg Aagaard, 527 Roskildevj, Glostrup, Denmark Filed Sept. 6, 1961, Ser. No. 136,273 Claims priority, application Denmark, Sept. 8, 1960,
3,565/60 6 Claims. (Cl. 50-4) The invention relates to a roof structure for supporting and attaching readily exchangeable, prefabricated plateshaped roof elements which at such of their edges as face each other are supported by purlins and rafters and over the rafters rest on elastic tightening fillets, the said roof elements being on their upper side at such of their edges as face each other fastened parallelly with the rafters beneath a rigid clamping strip which is attached to' the rafters by means of clamping bolts.
The object of the invention is to provide a roof in which the individual plate-shaped roof elements may be mounted and replaced rapidly without the use of special tools so that, with the roof elements mounted in their position, there is provided a fully finished well insulated and tight roof which may easily be made larger or diminished to suit requirements, the roof being in particular intended for a house with a steel framework incorporating outer columns placed in such manner along a throughgoing foot border that wall plates may easily be mounted and, if necessary, replaced, and in which floor carriers provided between the outer beams carry floor plates and supportremovable partitions. readily expanded or diminished by addition or by removal of the wall and floor elements and by means of the invention it is possible to vary the size of the roof in a corresponding simple manner.
An essential feature of a roof structure according to the invention consists in ridge plates mounted in extension of an overlapping each other at edges bent upwards in such manner that they may pass up over the ends of the tightening fillets lying over the rafters when the said filletsare resting on the roof elements. At their underside the saidridge plates carry a longitudinal holder plate with a central section of inversed U-shape or two separated holder plates which from the top part of the ridge plates extend beneath these at a distance corresponding to the thickness of the roof elements. Furthermore, to securely retain the upper roof element in the groove thus formed there is provided at least one clamping bolt in each rafter opposite the tightening elements located in the uppermost row. The result obtained is that it is no difficult problem to provide tightnessat the ridge of the roof since the roof will be perfectly tight if only the upper roof elements are pushed into the groove between the ridge plate and its holder plate, and no special holder members are required at the upper edge of the plates since they are safely retained in their position by the tightening element which is pressed down by the upper bolt.
To avoid any unnecessary work in tightening the clamping bolts for the tightening fillets it is convenient according to the invention that beneath each rafter there is provided a joint clamping strip for tightening the clamping bolts for the tightening fillet, the said clamping strip having key-shaped holes formed in such manner that they may be passed up over heads of downward projecting bolts of the tightening fillet, there being on either side of the narrowest part of the holes formed longitudi- Such a house may be 3,173,224 Patented Mar. 16, 1965 nal sloping cams which may rest in contact with a shoulder provided on the upper side of the bolt head for attachment of thetightening fillet by displacement of the clamping strip in its longitudinal direction. When a row of roof elements are arranged in the space between two rafters, the whole row may rapidly be fastened by displacing the clamping strip in its longitudinal direction. I
The clamping strip may be retained by friction alone, but may of course also be retained by a special attachment member. An essential feature of one embodiment of a roof structure according to the invention is, for example, that at the outer end of each rafter there is formed a guide for a holder member for a roof gutter section; the said holder members include a leaf springbeing tightened, is displaced upwards in the direction of the ridge, such part of the leaf spring or the attached holder member is located at the end of the clamping strip preventing downward displacement of the clamping strip.
In accordance with the invention the rafters may at regular intervals be connected with each other by connecting bars which at'either end have a pin to be introduced into a hole provided in a corresponding bow attached to the rafters. The connecting bars act as purlins for supporting the longitudinal edges of the roof plates in addition to ensuring that the raftersare rigidly retained in exact distance without rendering the structure more difiicult to disassemble.
The invention will be further described in the following with reference to the drawing, in which FIGURE 1 shows a part of the roof structure, viewed in perspective, 7
, FIGURE 2 is a section through a ridge plate with holder plate, H
I FIGURE 3 is a section through the roof plates parallelly withthe ridge, v
FIGURE 4 is a corresponding section through a joint between two roof plates resting on a rafter of a form different from that shown in FIGURE 3.
FIGURE 5 is a clamping strip for the clamping bolts of the tightening fillet, viewed from below,
FIGURE 6 is a longitudinal section through the lower part of arafter and a gutter attached thereto, and FIGURE 7 is a corresponding longitudinal section with a clamping strip of another shape. 7
Each rafter 1 constitutes support for a number of roof elements in the shape of roof plates 2' which consist of a frame 3 with outer surfaces 4,. between which is inserted insulating foamplastic 5. The roof plates rest at such of their edges as face'eaich'other on elastic tightening fillets packing or strips 6 which in the embodiment shown in FIGURE 3 are carried by a holder 7 of profiled plate riding on the upper side' of the rafter l which has the cross-section of inverted U. Through spaced holes provided in the rafter are passed regularly spaced clamping bolts 8 attached on a rigid tightening fillet 9 of profiled plate extending above the rafter throughout its longitudinal direction. A clamping strip it? is formed with keyshaped holes which may be passed over the heads of the Clamping bolts 8 after which the strip may be displaced so that oblique cams 11 along the narrow part of the holes are brought to rest against the upper side of the bolt heads, so that all bolts 8 may be tightened simultaneously by displacement of the clamping strip in its longitudinal direction and thereby press the tightening fillets 9 against the roof plates 2. In FIGURE 7 one end of the strip 10 is angularly bent and has a nut 21 welded to it and into which is screwed a threaded bolt 22 passed through a hole in a plate 23 at the end of the rafter 1 and which displaces the strip 10 when the bolts are tightened.
Connecting bars 12 serve to ensure exactly identical distance everywhere between rafters 1 lying beside each other, and the said bars have downwardly projecting pins 13 which pass into holes provided in clamps 14 welded to the rafters 1.
The uppermost roof plates close to the ridge are at their upper edges defined by ridge plates 15 which extend from rafter to rafter and have upwardly bent edges at their ends engaging each other. Between the upwardly bent end edges of the ridge plates 15 and the rigid tightening fillets 9 lying thereunder is provided sealing material 15a.
The gutter of the house is composed of sections 16 having a flange of U-shaped cross-section at one end to seize a bead-like flange of the adjoining gutter section. Opposite the rafters there is attached to the gutter sections a leaf spring 17 which is passed into a guide 18 formed of a channel section of inverted U-shape welded inside the U-section of the rafter 1. At the end of the leaf spring 17 is provided a hole which, when the gutter is in its position, received the downward-projecting end of the outer clamping bolt 8 of the rafter. The leaf spring 17 is located on a holder 19 which constitutes a stop preventing displacement of the clamping strip 10 after it has been moved into its tightening position.
To facilitate mounting of the upper roof plates 2 holder plates 20 are, as shown in FIGURE 2, attached by welding in the longitudinal direction beneath each ridgeplate, the said holder plates extending beneath the ridge plate at such distance from the latter that a roof plate 2 may be pushed over the holder plate and rest on it. Of course, also a single, continuous holder plate may be used, at tached along the ridge and having two webs, each extending beneath its separate roof surface.
