Abstract

This arrangement is characterized by an arch with a base for connection to the roof, and with attachments for securing the gangway, which attachments, by means of clamps gripping round the arch, permit a continuously level position of the gangway. <IMAGE>

Description

462 926 Figur 2 visar takbrygga med skyddsräcke ansluten till taket med uppfiningen (D). 462 926 Figure 2 shows the roof bridge with guardrail connected to the roof with the invention (D).

Figur 3 visar uppfinningen, 3B och SC i sektion och 3D i perspektiv.Figure 3 shows the invention, 3B and SC in section and 3D in perspective.

Figur 4 visar uppfinningens fot anpassad till tak belagt med takpannor.Figure 4 shows the foot of the invention adapted to roofs covered with roof tiles.

Figur 5 visar uppfinningen utan fästen men med fot anpassad för profilerad takplåt.Figure 5 shows the invention without brackets but with foot adapted for profiled roofing sheet.

Figur 6 visar uppfinningen monterad på lutande tak. \/ 462 926 Figur 3(B,C och D) visar uppfinningen bestående av en båge (1), här Visad som en cirkelbåge, men andra former är tänkbara, en fot (2) som antingen är i ett stycke med 1 som visas i fig 3 och 4 eller utformas som exemplifieras i fig 5, ett fäste (3) som består av två delar, med eller utan fast förbindning men kontinuerligt förskjutbara utmed bågens periferi, stöd (6) fast förenat med 3, fästmoment (4), som utgöres av en bygel i visat skyddsräcke och slutligen hål (5) för anslutning av skyddsräcke samt hål (7) för anslutning av takbrygga. Figur BB visar bàgen som ett rektangulärt tvärsnitt, vilket endast är ett av alla tänkbara. Runt tvärsnitt med fästena (3) inbördes förenade och bågen (1) uppdelad i två parallella bågar är två bland alla näraliggande alternativ.Figure 6 shows the invention mounted on a sloping roof. Figure 3 (B, C and D) shows the invention consisting of an arc (1), here shown as an arc of a circle, but other shapes are conceivable, a foot (2) which is either in one piece with 1 shown in Figs. 3 and 4 or designed as exemplified in Fig. 5, a bracket (3) consisting of two parts, with or without fixed connection but continuously displaceable along the periphery of the arch, support (6) fixedly connected to 3, fastening torques (4), which consists of a bracket in the guardrail shown and finally holes (5) for connecting the guardrail and holes (7) for connecting the roof bridge. Figure BB shows the arc as a rectangular cross section, which is only one of all conceivable. Round cross section with the brackets (3) interconnected and the arch (1) divided into two parallel arches are two among all adjacent alternatives.

Den geometriska avvägningen för (1) göres dels med vald vinkel alfa, som bestämmer en sektor av cirkeln med radien R, och dels med avståndet a, som är fästet 3=s rotationscentrums avstånd från cirkelbågens centrum.The geometric balancing of (1) is done partly with the selected angle alpha, which determines a sector of the circle with the radius R, and partly with the distance a, which is the distance 3 = s of the center of rotation of the bracket from the center of the arc of the circle.

Som framgår av fig 6 kan, efter det att bâgen (1) med fot (2) förankrats till taket, fästena (3), genom förskjutning utefter bågens (1) periferi avvägas i horisontalplanet, och fixeras i detta med fästelement (4), varefter en takbrygga B ansluts till (3). Räcket som automatiskt orienteras i vertikalplanet ansluts till hål (5).As can be seen from Fig. 6, after the arch (1) has been anchored to the roof with foot (2), the brackets (3) can be weighed in the horizontal plane by displacement along the periphery of the arch (1), and fixed therein with fastening elements (4). after which a roof bridge B is connected to (3). The railing, which is automatically oriented in the vertical plane, is connected to a hole (5).
