BALCONY FLOOR

Abstract: A balcony floor is made up of a plurality of equally long, horizontal sectional floor elements (1, 2, 3, 4) of steel sheet, which are arranged side by side and welded to each other, and of a horizontal sectional end element (6) of steel sheet which is disposed at each end of the sectional floor elements (1-4), extends at right angles to the sectional floor elements and has a vertical web portion (6a) which engages and is welded to the ends of the sectional floor elements. Each of the intermediate sectional floor elements (2, 3) and one (4) of the outer two sectional floor elements (1, 4) have at the side edge facing the other outer sectional floor element (1), a downwardly bent floor element-stiffening flange (2a, 3a, 4a) forming a recess for receiving a part of the horizontal portion of the adjacent sectional floor element (1, 2, 3) and also serving to stiffen the web portion (6a) of the sectional end element (6). The web portion of one sectional end element supports balcony railing attachments which are located substantially opposite a respective downwardly bent floor element-stiffening flange (2a, 4a).

Description: BALCONY FLOOR The present invention relates to a balcony floor. The object of the present invention is to provide a simple balcony floor which is less expensive than present-day balcony floors made from aluminium. The object of the invention especially is to provide a con¬ struction making it possible to manufacture the balcony floor from steel sheet. According to the invention, this object is achiev¬ ed by means of a balcony floor which is made up of a plurality of equally long, horizontal sectional floor elements of steel sheet which are arranged side by side and welded together, and of a horizontal sectional end element of steel sheet arranged at each end of the sec¬ tional floor elements, said sectional end elements extend- ing at right angles to the sectional floor elements and having a vertical web portion which engages and is welded to the ends of the sectional floor elements, character¬ ised in that each of the intermediate sectional floor elements and one of the outer two sectional floor ele- ments are provided, at the side edge facing the other outer sectional floor element, with a downwardly bent floor element-stiffening flange defining a recess for receiving a part of the horizontal portion of the adja¬ cent sectional floor element and also serving to stiffen the web portions of the sectional end elements, and that the web portion of one sectional end element supports balcony railing attachments which are located substan¬ tially opposite a respective downwardly bent floor element-stiffening flange. The invention will now be described in more detail hereinbelow with reference to the accompanying drawings, in which: Fig. 1 shows a balcony floor according to the pre¬ sent invention from above; and Fig. 2 shows the balcony floor in a section taken along the line II-II in Fig. 1. The illustrated balcony floor has a plurality (fou in the drawing) of equally long sectional floor element 1, 2, 3 and 4 of bent steel sheet which are disposed side by side and welded together along their long sides so as to form a horizontal bearing floor structure. As shown in Fig. 2, each sectional floor element 1-4 has a planar portion forming the top face of the balcony floor. Each sectional floor element, except the leftmost element 1 in Figs. 1 and 2, has along one side edge (the left in Figs. 1 and 2) a bend form¬ ing a recess the depth of which corresponds to the thickness of the sheet. As shown, the recess is intende to receive a part of the planar portion of an adjacent sectional floor element 1-3. Each sectional floor element, except the leftmost element 1 in Figs. 1 and 2, has a downwardly bent side edge flange 2a, 3a, 4a along the side edge of the ele- ment where the recess-defining bend is located. The side edge flanges 2a, 3a and 4a have a vertical portion and a horizontal portion, giving them an L-shaped cross section. The side edge flanges 2a, 3a and 4a serve to stiffen the floor elements so as to increase the bear- ing capacity thereof. The two intermediate sectional floor elements 2 and 3 are of identical design. The rightmost sectional element 4 in Figs. 1 and 2 differs from the two inter¬ mediate elements 2 and 3 only in that it is provided at its other side edge with a bend 4b forming one side edge surface of the balcony floor. The leftmost sectional floor element 1 in Figs. 1 and 2 differs from the rightmost element 4 only in that it has no recess-defining bend. Thus, it has a bend lb corre- sponding to the bend 4b of the sectional floor ele¬ ment 4. At both ends of the sectional floor elements 1-4, the balcony floor has an L-shaped sectional end element 5, 6 of bent steel sheet. The end elements 5 and 6, which are of identical design, have a vertical web portion 5a and 6a, respectively, which, as appears from Fig. 2, has substantially the same height as the bends lb and 4b of the outer sectional floor elements 1 and 4, respectively, and a horizontal flange portion 5b and 6b, respectively, extending a certain distance in underneath the sectional floor elements 1-4. The vertical web portion 5a, 6a of each sectional end element 5, 6 engages and is welded to the ends of the sectional floor elements 1-4, the downwardly bent side edge flanges 2a, 3a, and 4a of the sectional elements 2-4, like the side edge bends lb and 4b of the outer two sectional floor elements 1 and 4, serving to stiffen the web portions 5a and 6a. The balcony floor is mounted on the wall 7 of a house by means of a supporting beam 8 fixed there- to, which the balcony floor engages with the flange portion 6b of the inner sectional end element 6, and by means of two struts (not shown) which are fixed at one end to the wall of the house and anchored at the other end to a respective one of the outer two sectional floor elements 1 and 4. Opposite each of the side edge flanges 2a and 4a, the outer sectional end element 5 carries a bal¬ cony railing attachment 9. Each attachment 9 consists of a U-shaped member 10 fixed to the web portion 5a of the outer sectional end element 5 by means of two bolts 11 extending through the web portion on each side of the respective side edge flange 2a, 4a. The U-shaped member 10 and the web portion 5a thus clamp between them a balcony railing post 12. Since the web portion 5a is welded to the side edge flanges 2a, 3a and 4a, stiffening the web portion, and the side edge bends lb and 4b, the balcony posts 12 will be stably and reliably secured. This mounting becomes particularly stable and reliable since each railing attachment 9 is disposed in the vicinity of or, as illustrated, opposite one of the side edge flanges 2a, 3a, 4a.

Claims: CLAIMS 1. Balcony floor which is made up of a plurality of equally long, horizontal sectional floor elements (1, 2, 3, 4) of steel sheet, which are arranged side by side and welded to each other, and of a horizontal sectional end element (5, 6) of steel sheet arranged at each end of the sectional floor elements (1-4), said sectional end elements extending at right angles to the sectional floor elements and having a vertical web portion (5a, 6a) which engages and is welded to the ends of the sectional floor elements, c h a ¬ r a c t e r i z e d in that each of the intermediate sectional floor elements (2, 3) and one (4) of the outer two sectional floor elements (1, 4) are provided, at the side edge facing the other outer sectional floor element (1), with a downwardly bent floor element- stiffening flange (2a, 3a, 4a) defining a recess for receiving a part of the horizontal portion of the adjacent sectional floor element (1, 2, 3) and also serving to stiffen the web portions (5a, 6a) of the sectional end elements (5, 6), and that the web portion (5a) of one sectional end element (5) supports balcony railing attachments (9) which are located substantially opposite a respective downwardly bent floor element- stiffening flange (2a, 4a).
