Abstract

The vibration damper comprises a fastening member (7) for fastening to a roof construction member (4), a foot part (9) comprising an abutment face for abutment against an underroof cloth (2), and a spring (10) between the fastening member (7) and the foot part (9).

Description

  • The present invention relates to an underroof vibration damper.
  • A problem in underroofs is that their cloth or foil during unfavourable wind condition may start vibrating, thereby making an undesirable noise or getting damaged.
  • The object of the invention is to avoid this drawback in underroofs.
  • US-A-2 919 476 discloses a spring floor for e.g. a gymnasium, which floor is carrried by supporting springs which are housed between a fastening member for fastening an upper floor and a foot part resting on or abutting against and fastened to a lower floor structure. The purpurse of the spring floor is to protect people jumping on the floor against injuries caused by shocks from the jumps. This implies that the size and spring rate of the supporting spring would make it useless as an underroof vibration damper.
  • The object is according to the invention met by means of an underroof vibration damper which is characteristic in comprising a fastening member for fastening to a roof construction member, a foot part connected with the fastening member and comprising an abutment face for abutment against an underroof cloth, and a spring between the fastening member and the foot part. By mounting the vibration damper according to the invention in a roof construction it is obtained that the underroof cloth, when not vibrating, may be pressed slightly downwards, which makes it more difficult to start vibrating, and the spring has the effect that there is no danger of overloading of the underroof cloth by thermic movement or in case of heavy wind from an unfavourable direction, which might otherwise make the underroof cloth vibrate or flutter heavily.
  • The fastening member and the foot part may be interconnected by means of the spring, or the fastening member and the foot part may be interconnected by means of a flexible, but substantially unductile connecting member, the length of which in unbent condition preferably is smaller than the length of the spring in unloaded condition.
  • The invention will be explained in detail in the following by means of embodiments with reference to the drawing, in which
    • Figs. 1 and la show a roof construction with a vibration damper according to the invention, and
    • Figs. 2a and 2b is a front view and a lateral view of a preferred embodiment of the vibration damper.
  • Fig. 1 shows a roof contruction with rafters 1, above which lengths of underroof cloth 2 have been laid out, said cloth being secured by means of lists 3 over the rafters 1, and on which roof battens 4 are fastenend for carrying the roof tiles 5.
  • On some of roof battens 4 in the interspaces between the rafters 1 vibration dampers 6 are provided to prevent the underroof cloth 2 from vibrating due to influence from wind.
  • The vibration dampers, one of which is shown in a principle embodiment in Fig. la, comprise a fastening member 7 for fastening a roof construction element such as a roof batten 4, for instance by means of a nails or a screw, which is passed through a hole 8. The vibration damper 6 furthermore has a foot 9, with which it may abut on the underroof cloth, pressure from the vibration damper towards the underroof cover being distributed over a certain area. Between the fastening member 7 and the foot 9 a spring 10 is provided which in the embodiment according to Fig. la is intregral with the foot 9 and the fastening member 7. Hereby is achieved that the vibration damper 6 can abut resiliently onto the underroof cloth 2.
  • In a preferred embodiment shown in Figs. 2a and 2b of the vibration damper, the fastening member 7 is connected by two intermediate pieces 11 which are bendable on account of hinges 12. The intermediate pieces 11 are further hinged to the fastening member 7 and the foot 9, respectively, such that these two unimpeded by the intermediate pieces 11 can be moved towards each other. The spring 10' acts against such a movement, said spring being placed between the intermediate pieces and kept in place by protrusions on or recesses in the top side of the foot 9 and the underside of the fastening member 7. In the embodiment shown in Figs. 2a and 2b the fastening member 7, the foot 9 and the intermediate pieces 11 are formed integrally, the hinges 12 and the hinges between the intermediate pieces 11 and the fastening member 7 and the foot 9, respectively, are constituted by areas with reduced thickness as will be seen from Fig. 2a. The spring 10' may be dimensioned such that it is interlocked between the fastening member 7 and the foot 9, whereby the force, by which the underroof cloth under special wind conditons will act on the vibration damper 6, is to surpass the bias of the spring, before the cloth can move the foot 9 and consequently itself towards the roof batten 4, on which the vibration damper 6 is mounted.
