Definitions

  • the present invention relates to a track system on and along the edge of a roof and provided, for example, for carriages with booms from which working platforms are suspended.
  • Track systems of this type are known generally, and they include rails with crossties arranged in the usual manner, transversely to the rails and with regular spacing between the ties.
  • the crossties may be secured to the rooftop of the building. Regular spacing of these ties generally ensures even distribution of load on the respective base, which in this case, happens to be a roof.
  • the direction of the walls carrying the roof is sometimes not identical with the direction of the ties. Consequently, the roof must be provided for additional load bearing capability, so that particularly the portion of the roof not directly supported by wall structure suffices to carry the load of the track system and of the vehicle(s) running thereon.
  • a sloping or oblique track system poses, of course, problems as to the driving conditions for any vehicle.
  • a heavy boom, crane, or other cantilever construction is a particularly troublesome vehicle.
  • the tracks mustbe installed to establish horizontal driving conditions but the leveling of the track system is often quite complicated.
  • the system once installed must be checked regularly and quite frequently, particularly as to position of leveling shims or the like, sufficiency thereof or wear or displacement, etc.
  • the crossties should distribute the load of the track and carriage system, so that the load can be distributed into the walls carrying the roof on which the track system is to be installed, obviating the need for otherwise unnecessary roof reenforcement.
  • the supporting ties are provided and distributed so that at least two are available for each crosstie.
  • the crossties have bolts, pins or posts that are inserted into the openings of the respective support ties, there being spacer tubes or rings disposed between the support ties and the crossties to establish a particular level for the (upwardly directed) supporting surface of the crossties.
  • the crossties should be laid regularly as usual and extend transverse to the direction of the track to be laid, but the crossties are placed only onto the support ties not directly on the roof. The rails are then installed on the crossties in accordance with the desired track.
  • the load can be distributed onto the roof independently from the direction of extension of the rails and of the crossties, as the support ties and sills do not have to have specified direction relative to the railcrosstie system; the support ties are installed in accordance with the roof structure, and further in accordance with the wall structure underneath as supporting the roof.
  • the support ties can be turned on the respective bolt axis to assume the most favorable direction as far as distributing load onto the roof is concerned.
  • the support ties can be made of any material, wood or iron. They are, however, preferably provided as hollow steel profiles.
  • the spacer rings or bushings level the rail system relative to the roof to assume horizontal disposition with respect to any vehicle thereon. Annular shims and/or washers may provide for local fine adjustment of the crosstie level. The rail system once established does not require any further maintenance as far as level position is concerned. The spacer bushings will not slip out from under the crossties for any reason such as shaking of the building or weather.
  • the bolts should have a collar to be locally widened in diameter where affixed to the crosstie.
  • the collar surface has diameter and width at least equal to or larger than the respective (axial) annular support surface of the spacer rings or bushings.
  • Such dimensions ensure'that the annular spacer elements do not damage the crossties during extensive and longlasting use of the track system.
  • the collar bears against the support surfaces of the spacer and vice versa.
  • the inner diameter of the spacer rings or bushings can be larger than the outer diameter of the bolts (other than the collar portion) which facilitates installation and, if necessary, exchange of the spacer.
  • damping means are disposed between the annular spacer elements and the support ties and sills.
  • the damping elements impede noise propagation from the rail system via the support ties into the building. Also, any tilting action on the rails is balanced as far as load pressure on the roof is concerned, due to elasticity of the damping means. Washers between the damping means and the spacers prevent damage of the damping means during operation.
  • FIG. 1 is a cross section through a rail support system in accordance with the preferred embodiment of the invention
  • FIG. 2 is a cross section transverse to the section of FIG. 1 and on somewhat smaller scale;
  • FIG. 3 is a top elevation of a representative system improved as to details as shown in FIGS. 1 and 2.
  • Each crosstie l is made of profile steel with U-shaped cross section, whereby the legs of the U extend down, and the bottom of the U serves as supporting surface for the rails.
  • Each crosstie has two bolts, pins or posts such as 2, 2', welded to the tie in-between the legs and extending parallel thereto and in down direction. Immediately below the welding joint, each bolt has wider diameter or is provided with a, possibly, integral collar 9,9.
  • a plurality of support ties such as 3 and 3' are distributed over the top of a roof.
  • Each support tie 3,3, is of tubular construction but rectangular cross section, i.e., it is a hollow section and has an opening 4 through which passes one of the pins, posts or bolts 2, 2. The relative position of a crosstie on a support tie is determined as follows:
  • a damping plate or disk 7 with central opening rests directly on support tie 3, and in alignment with the aperture or opening 4 therein.
  • a protective, annular washer sits on annulus 7, and a spacer annulus such as a bushing rests thereon.
  • the upper axial end face of tube or bushing 5 bears against the collar 9 and hereby supports crosstie 1.
  • the support ties 3 and 3' lie on the roof in a manner that distributes best any load into the roof and any wall structure that supports the roof. Also, location of support girders etc. of the roof, should be taken into consideration for the orientation of the ties 3 and 3' etc. Moreover, the crossties must have orientation and level in accordance with the track structure such as extension and level thereof as a whole. Therefore, the orientation of the support ties relative to the crossties has a quasi-random character.
  • any spacer bushing determines the relative height of a crosstie above a support tie or sill and should be chosen on basis of the local requirement.
  • the bushings 5, 5, may, however, be of standard size, and additional annular washers may be added for fine trimming of the level of the crossties.
  • the rails are affixed to the several crossties by clamping and mounting structure 11, 11', shown in FIG. 2 only, and being of conventional construction. As decated close to the roof edge, so that these support ties are all supported on or close to that roof portion, underneath of which runs the outer wall of the particular building.
  • crossties l are interconnected by similar, hollow sections 12, and a protective guard picted particularly in FIG. 2, only one of the bolts 2 of a crosstie is secured to the tie directly underneath one of the rails 10.
  • the other bolt (2') is affixed to the same crosstie at one end thereof.
  • This arrangement of bolts and support ties combines favorable load distribution from the track-withcarriage system onto the support ties, without exerting excessive bending forces onto the crossties, and without compelling the support ties to be. positioned too close to each other.
  • the elements 2, 3, 4', 5, 6, 7' and 9' correspond to those without and denote the crosstie-support tie relation at the end .of the crosstie.
  • the second rail 10 is located between the two support tie-crosstie systems.
  • the track system thusly provided may serve as track for a vehicle with a cantilever boom or the like from which is suspended a working platform.
  • FIG. 3 shows the track system as running along and close to the edge of a roof, and the working platform is to be lowered along the wall beyond the roof edge.
  • total spacing structure 5-6-7 (or 5'-6'-7') as effective in each location, is held in position by the respective posts 2 or 2, as welded onto crosstie 1.
  • the posts 2, 2, are sufficiently long so that they will always project to some extent into the hollow support ties 3.
  • the resilient damping washers, 7, 7 prevent any hard metal-to-metal contact between the superstructure and the support ties so as to inhibit noise propagation.
  • each crosstie having a support tie underneath is 10- rail 8 is secured thereto and runs along the extension of the tracks, guarding the rails as well as the roof edge.
  • the top view of FIG. 3 shows how the system can readily accommodate a projection of the building.
  • a rail system for installation on the roof top of a building as track system for vehicles with cantilever cranes, booms for suspending working platforms, using pairs of rail tracks, comprising:
  • each support tie disposed along the track on the roof top and in orientations in accordance with the construction of the said roof as supported by carrying walls or the like, each support tie provided with an upwardly directed opening;
  • a plurality of crossties for supporting the rails, and for mounting on the support ties, there being at least two of the support ties of the plurality of support ties associated with a crosstie of the plurality of crossties;
  • each pin secured to a crosstie of the plurality, and respectively received by the openings of the two support ties associated with the crosstie, each pin having a collar where secured to the respective crosstie, the, collar having an annular surface, and
  • a bushing for each pin interposed between the crossties and the respective support ties and received by the respective pins and bearing axially against the collar from below, the axial end face of the bushing having diameter not larger than the annular surface of the collar for adjusting the level of the respective crosstie in relation to the respective support tie as disposed on the said roof top.
  • the support ties being hollow sections of rectangular cross section, the crossties have U-shaped cross section with downwardly directed legs of the U, the pin extending in-between the legs.
  • a rail system for installation on the roof top of a building as track system for vehicles with cantilever cranes, booms for suspending working platforms or the like, using pairs of rail tracks comprising:
