Definitions

  • Subject of the invention is a flange consisting of separate members connected together during assembly on the roof, sealing the joint of the roofing with the adjoining elements of the sheet metal framing being a part of the building structure passing through the roof.
  • a structure can be e.g. a frame of a roof window or roof hatch, or of another structural element of the building. The basic function of the frame is securing the joint from precipitation like rain, snow, etc.
  • a solution known from the patent application WO 99/51835 and the patent specification US 6 457 279 consists of a weather protecting sheet-metal frame sheathing of the joint of a part of the building penetrating the roof with the adjoining roofing, which is a geometrically complex shape element including vertical arms provided with formed profiling serving to tack it to the next similar element of the flashing.
  • the drawback of that solution is the intricate process of cutting-out the sheet-metal element, and the fact that the element cannot have more than two vertical arms provided with formed profiling to connect it with the next element, which limits the possibility of adjusting longitudinally two overlapping elements.
  • the method of profiling the edge perpendicular to the roof causing geometrical stiffening hinders in practice their free and manual bending. This necessitates using special hand tools and entails additional time and labor outlay.
  • the aim the invention is making the flange as an element of the flashing of scale-type roofing, the flange consisting of members connected together during assembly on the roof, and sealing off the joint of the roofing with the adjoining elements of the flashing being a part of the building structure penetrating the roof.
  • the flange sealing the named joints consists of members the form and size of which is fitting the particular roofing element.
  • That kind of roofing requires assembling the flange in concert with the roofing by placing the successive layers starting by the lowest one.
  • the separate flange members are usually fastened by covering their arm parallel to the roofing surface by the following layers, while the edge abutting to the external surface of the structure penetrating the roof is usually being fixed by nails or screws. Since, however, the emergence on the market of roof windows made of PVC shapes, using such type of fastening became inadvisable. It became thus necessary to develop a fastening system including connecting and fixing elements being a part of the flange and eliminating altogether screws and nails as fasteners.
  • the flange according the invention enables easy and durable manual assembly of both the whole flange as of its particular parts without additional tools
  • the flange in the form and shape of a whole framing of the structure penetrating the roof consists basically of three types of parts ⁇ the bottom flange, the top flange, and the symmetrical side strips consisting of members, the size of which depends on the size of the corresponding roofing elements.
  • the shape of the members of the side strips basically in form of the letter L, enables their overlapping connection in the direction of the roof pitch.
  • the essential and indispensible feature of these members is providing tight and durable protection against weather on the connection of the part of the building penetrating the roof with the adjacent roofing.
  • the distinguishing feature of the invention consists in the shape of the fixing elements, which connect the contiguous members of the flange in an effective and durable manner.
  • the toothed fixing elements made by crosswise incisions on the external edge of the arm adjacent to the external surface of the building structure penetrating the roof, are an integral part of the particular members of the flange.
  • the total width of the fixing element and the incisions adjacent to it enables joint bending. That condition is advantageously satisfied by keeping the condition that the sum of the widths of the fixing element and the adjacent incisions is the same in the corresponding flange members being joined. Full blocking of any relative movement of two flange members is being advantageously achieved by providing equal widths of the fixing elements and at the same time minimizing the widths of the adjacent incisions.
  • a distinguishing feature of the invention is also the water draining groove created in the arm of the member generally laying on the roof surface, lying parallel to the roof pitch direction. That groove, functioning as a gutter, consists in its cross-section view of three sides.
  • the bottom side is preferably parallel to the plane formed by the upper surface of the battens, and the sides, preferably perpendicular to the bottom, act at the same time as gutter sides for the drained water, also fixing and locking any crosswise movement.
  • the side of the grove which is closer to the bending edge of the whole member, is preferably an extension of the member arm adjacent to the building structure passing through the roof.
  • the opposite side basically parallel to the first one, connects the groove bottom with the further part of the member, which is a flat surface parallel to the surface the roofing elements and the dimensions of which are fitting these elements.
  • the actual thickness of the roofing elements and their overlapping manner of assembling on the roof causes an out-of-parallel of the plane formed by the battens in relation to the plane of arranging the roofing elements.
  • the existing angle is accounted for in the flashing element, i.e. the bottom is parallel to the battens, while the side overlapping the roofing element is parallel to that element.
  • fig. 1 presents the flange in disassembled state
  • fig. 2 ⁇ the flange assembled into a closed loop
  • fig. 3a a side member with fixing elements made on the whole length of the arm, in its state before assembling
  • fig. 3b - a side member with two fixing elements in its state before assembling
  • fig. 4 ⁇ the joint of two flange members before bending the fixing elements
  • fig. 5 ⁇ the joint of two flange members after bending the fixing elements.
  • the invented flange in the first example of execution, in its state before assembling, is shown in fig. 1 , and consists of four main parts: the bottom flange 1 , the top flange 2, and the side strips 3 consisting of the side members 4 the size of which depends on the size of the corresponding roofing element.
  • the number of members of the side strips 3 does not depend on the construction of the flange, but on the size of the structure penetrating the roof and the number of rows of the small-size roofing elements.
  • the dimension of the flange in the direction parallel to the battens is constant and depends on the corresponding dimension of the penetrating structure. This means that the top flange 2 and the bottom flange 1 have constant widths, determined by the manufacturer.
  • the shape of the flange upon joining its parts into a closed loop is shown in fig. 2 .
  • Fig. 3a shows a particular side member 4 in its state before assembling.
  • the arm 5 of the flange member adjoining the building structure is made with incisions having the width k resulting from the applied fabrication technology, and the incisions are normally perpendicular to the external edge of the arm 5.
  • the incisions form a series of toothed fixing elements 6, having preferably an equal width I , and being spaced with a pitch which is one of the multiples of the sum of the width of one fixing element 6 and the incision width k.
  • the height of the fixing elements m is preferably small, but taking in account the possibility of bending them by hand.
  • the second arm 7 of the side member adjacent to the roofing surface consists of two non-parallel surfaces: the bottom one 7a parallel to the surface made by the structural element of the roofing, the surface 7b , parallel to the plane of the laid roofing element, and of the third, connecting surface 7c, perpendicular to the two preceding ones.
  • the surfaces 7a and 7c intersect at the line, which is parallel to the battens.
  • the relative position of the bottom surface 7b and the surfaces adjacent to it, i.e. the connecting surface 7c and the arm abutting to the structure passing through the roof creates a water draining channel.
  • the surface 7a is basically parallel to the plane formed by the structural elements of the roofing, while the surface 7b is basically parallel to the elements of the roofing.
  • the water draining channel constitutes moreover an element stiffening and locating the relative position of the members of the flange.
  • the fixing elements 6 upon bending them jointly, it forms a lock blocking all degrees of freedom of the flange members, stopping any relative movement.
  • the described constructive solution enables fast, proficient, and effective joining of the consecutive members to each other, with no use of tools, which results in considerable economy of time and labor outlay.
  • the solution makes it generally possible to adjust the elements of the flashing to the majority of commercially available small-size roofing elements.
  • the flange according the second example of execution is structurally equal to the flange of the first example.
  • the difference consists in applying the side element of the flange according to fig. 3b , having a minimum number fixing elements. It is a solution less universal, but having the advantage of lesser manufacturing costs. Considering the standardization of roofing elements, one can adjust the spacing between the fixing elements to typical lengths of small-size roofing elements.
  • the arm 5 of the flange member adjacent to the building structure has two fixing elements 6 spaced so as to fit the applied solution of the roofing structure.
  • the fixing elements 6 are made by two twin cuts with a width k as described in the first example, and a spacing making it possible to bend by hand the so formed tooth.
  • the distance between the incisions determines the width l of the fixing element. Keeping equal the dimensions m , l , and k safeguards the possibility to bend jointly the fixing elements, having previously adjusted the side members 4 and forcing overlapping of the fixing elements.
  • the remaining functional and constructive features are the same as in the first example of execution.
