FR2596091A1 - Roof structure using oblique ties between the purlins and corresponding roofing elements - Google Patents

Abstract

The invention relates to a method for using materials making it possible to construct elements for constructing buildings without braced frames and without horizontal devices for channelling rainwater. This method uses purlins 1 directed diagonally, resting on ties 2 of the roofing raised members at the edges 3 of the "water collectors" 4 of the rainwater pipes 5. The method according to the invention is particularly intended for manufacturing elements for constructing buildings.

Description

The present invention relates to a method of manufacturing building construction elements allowing:
- to bring back on the load-bearing points, the stresses exerted by the weight of the covers without resorting to triangular structural elements (trusses or small farms).

- to collect the rainwater runoff from these covers in
privileged points without resorting to horizontal roof drains.

 - to realize the vertical load-bearing elements (walls, porticos), according to identical construction elements.

Traditionally, constructions covered with pontic roofs are carried out by means of vertical load-bearing elements (walls, gables, gates) and triangular frame elements (trusses or small farms) allowing the stresses exerted by the weight of the covers to be reduced. , cur these vertical elements then on the ground.

Rainwater is collected at the bottom of these covers by horizontal sewers (gutters, oheneaux) which. make them transit towards the downspouts of rainwater to be discharged barefoot from the construction.

The method according to the invention makes it possible, by inserting oblique struts between the purlins, launched diagonally, to direct the stresses exerted by the weight of the covers, towards the vertical load-bearing elements (walls, gantries).

The covers are raised on the banks by a vertical element which makes it possible to direct the rainwater towards water boxes "then to lead them to the foot of the constructions by downspouts of rainwater
The vertical load-bearing elements (walls, porticoes) can be easily modulated, the roof penten being identical on four sides of the element, when the plane of the latter enters a rectangle; if the plan ent. a square, these four vertical elements can be identical,
Figure I shows in plan and axonometry, the method and its implementation on a square plane.

 Figure 2 shows an extrapolation of the process to a rectangular plane.

 FIG. 3 presents a variant of FIG. 2.

 Figure 4 shows a simulation of assembly of square plane elements.

 FIG. 5 presents a simulation of assembly of elements of rectangular plane.

The arrangement shown in Figure I includes horizontal load-bearing elements (purlins) (I), do mainteneiseu (2), das lclève -clent elements (3) on the edges of the covers, a water box (4), a descent of 'rainwater (5), vertical load-bearing elements for transmitting stresses to the ground.

Claims (3)

CLAIMS I) Method of manufacturing building construction elements in which the horizontal elements carrying the covers (I) are launched diagonally, characterized in that the stresses exerted on these horizontal elements are transmitted to the vertical -cal bearing elements (walls gantries) by oblique spacers. (2). 20) Method according to claim I characterized in that an element (: 3)  of raising the covers in rivo directs the rainwater flowing  iant cur these covers, towards "water boxes" (4) then towards the ground  by downspouts of rainwater (5). 30) Method according to claims I and 2 characterized in that it  allows the use of vertical load-bearing elements (walls  portal frames) identical nor the base plane is square (figI, fig4). 40) Method according to reven-iications I and 2 characterized in that it  allows the use of trapezoidal construction elements  whose slope is identical, for the manufacture of the elements  vertical carriers (walls, porticos) when the plane is not square  (fig2, fig5).
