METHOD FOR MOUNTING A BUILT-IN BALCONY AND BUILT-IN BALCONY

Abstract: When building in a balcony, which comprises a balcony slab (1) and a roof slab (2) located above the balcony slab, at least one lower supporting element (3) and at least one upper supporting element (8), which each have a vertical branch (3b, 8b), are so attached to, respectively, the balcony slab (1) and the roof slab (2) that their vertical branches (3b, 8b) extend upwards outside the edge surface (6, 11) of the respective slabs. A frame, which has a lower sectional element (16) provided with a longitudinal groove (18) and a vertical outer flange (19) on the underside, and an upper sectional element (15) provided with a vertical flange (20) on the upper side, is so placed on the lower supporting element (3) that the vertical branch (3b) thereof is inserted in the groove (18). The vertical flange (19) of the lower sectional element (16) then extends down over the vertical branch (3b) of the lower supporting element (3) on the outside thereof, and the vertical flange (20) of the upper sectional element (15) extends up over a substantial part of the vertical branch (8b) of the upper supporting element (8). The vertical flange (20) of the upper sectional element (15) is applied against the vertical branch (8b) of the upper supporting element (8) and is attached thereto.

Description: METHOD FOR MOUNTING A BUILT-IN BALCONY AND BUILT-IN BALCONY This invention relates to a method for mounting, between a horizontal lower slab, such as a lower balcony slab, and a horizontal upper slab, such as an upper bal¬ cony slab, located straight above the lower slab, a frame having an upper and a lower horizontal, sectional element and being adapted to support wall elements for building in, at least partly, the space between the slabs. The in¬ vention further concerns a balcony comprising a balcony slab and a roof slab located straight above the balcony slab, which between them support a frame of the above type. In a method of this type known from Swedish Patent Specification 467,264, at least two lower pins and at least two upper pins, which are formed with a transverse through hole, are so fixed in, respectively, one of the edge surfaces of the lower slab and the corresponding edge surface of the upper slab that they project hori¬ zontally from these edge surfaces, the transverse hole being vertically directed; a peg is so inserted in the hole of each lower pin that its upper portion projects from the pin; the frame, whose lower and upper horizon¬ tal, sectional elements have been formed with vertical holes whose positions on the respective sectional ele¬ ments correspond to the positions of the lower and upper pins on the edge surfaces of the lower and upper slabs, respectively, is so arranged on the lower pins that the upper portions of the pegs inserted therein are intro¬ duced into corresponding holes in the lower sectional element; and a peg is so inserted in the hole of each upper pin that its lower portion is introduced into a corresponding hole in the upper sectional element. This prior-art method is easily implemented and allows certain dimensional tolerances in the vertical direction as regards the frame, but necessitates fairly extensive supplementary work in the form of the mounting of cover strips and the sealing of joints, this method being used for building in superimposed balconies. An object of the present invention is to provide a method which also permits dimensional tolerances in the vertical direction as regards the frame and which is easier to implement than the prior-art method, while at the same time minimising the supplementary work referred to above. According to the invention, this object is achieved by a method which is of the type stated by way of intro¬ duction and which is characterised in that at least one lower supporting element and at least one upper support- ing element, which each have a vertical branch, are so attached to, respectively, the lower and the upper slab that their vertical branches extend upwards slightly out¬ side the edge surface of the respective slabs, that the frame, whose lower sectional element is formed with a longitudinal groove on the underside, is so placed on the lower supporting element that the vertical branch thereof is inserted in the groove, the lower sectional element of the frame having a vertical flange which extends down over the vertical branch of the lower supporting element on the outside thereof, and the upper sectional element of the frame having a vertical flange which extends up over a substantial part of the vertical branch of the upper supporting element, and that the vertical flange of the upper sectional element is applied against the verti- cal branch of the upper supporting element and is attach¬ ed thereto. Preferably, the supporting elements are adjustably attached to the respective slabs in such a manner that the distance between each vertical branch and the edge surface of the slab is adjustable. The vertical flange of the upper sectional element is conveniently attached to the vertical branch of the upper supporting element by means of self-drilling screws. Another object of the invention is to provide a balcony, which is at least partly built in, by using the method according to the invention. According to the invention this object is achieved by a balcony which is of the type stated by way of intro¬ duction and which is characterised in that at least one lower supporting element and at least one upper support- ing element, which each have a vertical branch, are so attached to, respectively, the balcony slab and the roof slab that their vertical branches extend upwards slightly outside the edge surface of the respective slabs, that the frame, whose lower sectional element is formed with a longitudinal groove on the underside, rests with its lower sectional element on the lower supporting element in such a manner that the vertical branch thereof is inserted in the groove, that the lower sectional element of the frame has a vertical flange extending down over the vertical branch of the lower supporting element on the outside thereof, that the upper sectional element of the frame has a vertical flange extending up over a sub¬ stantial part of the vertical branch of the upper sup¬ porting element, and that the vertical flange of the upper sectional element is applied against the vertical branch of the upper supporting element and is attached thereto. The invention will now be described in more detail with reference to the accompanying drawings, in which Fig. 1 is a front view of a built-in balcony accord¬ ing to the invention, and Fig. 2 is a section of the balcony in Fig. 1 taken along line II-II, two of three glass panes being, how¬ ever, displaced to the left with respect to Fig. 1. The illustrated balcony comprises a horizontal bal¬ cony slab 1 and a horizontal roof slab 2, which is locat¬ ed straight above the balcony slab 1 and which here con- stitutes the balcony slab of a superjacent balcony. Like¬ wise, the balcony slab 1 constitutes the roof slab of a subjacent balcony. The two slabs 1 and 2 are made of con¬ crete or steel and are, in conventional manner, attached to the wall of a house (not shown) . Two L-shaped supporting elements 3, which each com¬ prise a horizontal branch 3a and a vertical branch 3b, are, by means of bolts 4, so attached to the balcony slab 1 that the horizontal branches 3a are applied against the under- side 5 of the balcony slab 1 and the vertical branches 3b extend upwards slightly outside the front edge surface 6 of the balcony slab 1. The bolts 4 extend through elongate holes 7 formed in the horizontal branches 3a, enabling a certain adjustment of the distance between the vertical branches 3b and the edge surface 6. Two L-shaped supporting elements 8, which are iden¬ tical with the supporting elements 3, are, by means of bolts 9, so attached to the roof slab 2 that their hori¬ zontal branches 8a are applied against the underside 10 of the roof slab 2 and their vertical branches 8b extend upwards slightly outside the front edge surface 11 of the roof slab 2. The bolts 9 extend through elongate holes 12 formed in the horizontal branches 8a, enabling a certain adjustment of the distance between the vertical branches 8b and the edge surface 11. The balcony is a built-in balcony and is, at the front side, provided with a fixed, lower wall panel 13 of sheet-metal and three glass panes 14, 14', 14", which are horizontally displaceable in relation to each other. The wall panel 13 and the glass panes 14, 14', 14" are mount¬ ed in a frame having an upper horizontal, sectional ele¬ ment 15, a lower horizontal, sectional element 16, and an intermediate horizontal, sectional element 17. The wall panel 13 is mounted between the lower sectional element 16 and the intermediate sectional element 17. The glass panes 14, 14', 14" are, in known fashion, mounted between the upper sectional element 15 and the intermediate sec- tional element 17 and are displaceable in relation to each other. Conveniently, the sectional elements 15, 16, 17 are made of aluminum. The drawings show a corresponding lower, sectional element 16' forming part of a frame arranged at the upper balcony. The two lower sectional elements 16 and 16' are identical. The lower sectional element 16 (16') is formed with a longitudinal groove 18 (18') on the underside and is equipped with an outer flange 19 (19') projecting verti¬ cally downwards at the front side. The upper sectional element 15, which in the illustrated embodiment consists of two sectional parts riveted together, comprises, at its central portion, a flange 20 projecting vertically upwards. With its lower sectional element 16, the frame rests on the lower supporting elements 3. The vertical branch 3b of each supporting element 3 is thus placed in the groove 18 of the lower sectional element 16. The lower sectional element 16 is applied against the front edge surface 6 of the balcony slab 1 by the intermediary of a rubber strip 21 sealing against flue gases. The frame provided at the upper balcony is supported in the same way by the upper supporting elements 8, the lower sectional element 16' applied against the front edge surface 11 of the roof slab 2 by the intermediary of a rubber strip 21' sealing against flue gases. The upper sectional element 15 of the frame is, with its vertical flange 20, applied against the vertical branches 8b of the upper supporting elements 8 and is attached thereto by means of self-drilling screws (not shown) . As appears from the drawings, the vertical flange 20 of the upper sectional element 15 extends up over a sub- stantial part of the vertical branches 8b of the upper supporting elements 8, and the vertical flange 19' of the lower sectional element 16' of the superjacent frame CTl
