Definitions

  • the invention relates to an arrangement for supporting wall or roof coverings of a building, such as an indus ⁇ trial building, comprising at least two frame works each having at least two pillars and at least one roof covering supporting beam arranged thereon.
  • the frames must be made strong and stable and therefore they are comparatively expensive to manufacture as well as to mount. It is the carrying capacity of the covering member used for walls and roofs which is the determinant factor for how great the interval between two adjacent frame works can be. It is of course possible to increase the carrying capacity of the covering member by increasing the material thickness, but at a certain consumption it will not be economical any longer. When trapezoid profiled plates are used this thickness results in a carrying ca ⁇ pacity corresponding to not more than 5 to 6 meters bet ⁇ ween two adjacent frame works. It is primarily snow loads which determine the dimensions of the coverings arranged on the roof frames, while especially wind loads determine the dimensions of the wall coverings.
  • the object of the present invention is to provide an ar ⁇ rangement described above which is considerably cheaper than the ones already known, by making a substantially increased distance between two adjacent frames possible.
  • an arrangement according to the first paragraph has an elongated auxiliary bearing member extending substantially in parallel with the beams, which is suspended on and between said beams by means of traction members, that the beams and the axui- liary bearing member form a plane for supporting the roof covering or possibly secondary bearing means for the roof_ covering, that the traction members are attached to the beams and the auxiliary bearing member so as to transmit forces while generating points of force action on the beams being located closer to said plane than points of force action generated on the auxiliary bearing member, so that loads on the roof covering in the region of the auxiliarybearing member are transmitted through the traction members to the beams, that at least one elongated wall covering supporting auxiliary member is arranged between two pillars belonging to different frame works and ex ⁇ tends substantially in parallel with the plane of the pillars, that the lower extremity of the latter support member is fixed in a base and its upper extremity is con ⁇ nected to an auxiliary bearing member so that substantially horizontal loads,-

  • the distance can now without any- problems amount to 10 to 15 meters, without any changes of the roof or wall covering layers.
  • auxiliary bearing members and the auxiliary support members loads on the roof and wall portions are transmitted between frame work to frame work, which are dimensioned so as to be able to support every load adapted thereto.
  • Another advantage of a small number of frame works consist in the fact that they very easily, can be brought into mu ⁇ tual alignment and after that a very simple adjustment and orientation of the auxiliary bearing member and the auxiliary support member can take place.
  • auxiliary bearing members and the auxiliary support member would be exchanged for strong frame works such an easy adjustment would not be possible, but considerably more time would be consumed in the mounting and it would also give rise to greater crane costs.

  • the frame works is constituted by comparatively thick beams, in this case in the form of I-beams, while the auxiliary bearing mem ⁇ bers and the auxiliary support members is constituted by considerably thinner beams, which here are shown as Z-beams.
  • the roof covering 2 consists of an outer layer 8 of trapezoid profiled plate, an insulating layer 9 located therebelow and a lowermost layer 10 of trapezoid profiled plate, the profiles of which extends in parallel with the ridge, i.e. substantially perpendicularly to the auxiliary bearing members 6.

  • the roof covering supporting beams 5 are here consti ⁇ tuted by I-beams, the upper rib of which is secured, preferably by screwing, riveting or the like, to the lowermost layer of the roof covering and thus as a result thereof support the same.
  • Auxiliary bearing members 6 are through traction members 11 suspended between two adjacent beams 5. In this case there are two auxiliary bearing members which extend substantially in parallel with the beams.
  • the traction members may be constituted by wires, rods or other suitable means transmitting trac ⁇ tion forces.
  • the auxiliary bearing members are consti ⁇ tuted by Z-beams, the upper rib of which bears against the inner layer 10 and is secured thereto, preferably by screwing och riveting.
  • the traction members 11 are anchored in clutches 12 on the beams 5 and the auxiliary bearing member 6, which will be described more in detail later on while referring to fig 7.
  • the suspension of the auxiliary bearing members 6 on the beams 5 through the traction members 11 is carried out at a plurality of suspension points distributed with suitable intervals along the beams.
  • the traction elements connected to one and the same beam 5 at different sus ⁇ pension points extend in planes being substantially pa ⁇ rallel to each other, the normal of said planes being substantially parallell to the longitudinal direction of the beams 5.
  • a means 13 may be arran ⁇ ged for stretching the traction member in question.
  • the stretching means are here of the screw type and con ⁇ sists of conventional stretching screws, but they may have any arbitrary configuration.
  • the traction members 11 are connected to the beams 5 and the auxiliary bearing members 6 in a force transmitting manner while generating points of force action on the beams being located closer to the inner layer 10 of the roof covering than the point of force action generated on the auxiliary bearing member 6.
  • This being the case appears clearly in fig 2 from the angle that the traction members 11 make with the extension of the inner roof covering layer while extendin from a beam 5 to an auxiliar 'bearing member 6.
  • the points force action on the auxiliary bearing member 6 of a trac ⁇ tion member 11 extending between two auxiliary bearing members are of course located at a distance from the roof covering supporting plane.

  • Auxiliary support members 7 extending substantially in parallel with the pillars are between the pillars 4 of the frame works also fixed to the base.
  • the auxiliary support members 7 are here two in number.
  • auxiliary support members 7 which similar to the auxiliary bearing members may • be constituted by Z-beams.
  • the wall covering 1 could of course also be arranged completely outside or inside the pillars 4 and the auxiliary support member.
  • Each of the auxiliary support members 7 is at its top connecte to an auxiliary bearing member 6 belonging thereto. How this connection may be realized is shown more in detail in figs 4 to 6.
  • the connection between auxiliary bearing member and auxiliary support member may preferably per ⁇ mit a certain freedom of movement in the vertical directio of the auxiliary bearing member with respect to the auxi ⁇ liary support member. This freedom of movement ensures that the auxiliary bearing members do not transmit any loads from the roof covering to the auxiliary support members. These loads may then be completely absorbed by the frame works .
  • connection permits a movement in a direction w " hich is substantially perpendicular to the roof covering plane.
  • the connection is constituted by a guiding arrangement, which according to a first variant is designed with a projection 15 attached to the upper extremety of each auxiliary support member, said protection projects into and is guided desplacable in a slot 16 in the associated auxiliary bearing member 6.
  • a second variant (see fig 5) consists of arranging the projection 15 on the auxiliary bearing member 6.
  • the auxiliary support member has a slot in its upper extremety for guided displacement of the projection 15. It appears from fig 6 that the projection in this variant is constituted by a T-beam, which is displaced in the slot 16 formed by the beam 17.
  • the projection and the slot also extend substan ⁇ tially perpendicularly to the roof covering plane.
  • the bearing ' members 6 and the auxiliary support members 7 could be connected by a bolt extending- substantially horizon ⁇ tally and perpendicularly to the longitudinal directions of both of the members 6 and 7, said bolt projecting through bores in the members 6 and 7.
  • the bore in at least one of the members 6 and 7 is longish in the verti ⁇ cal direction, for example in a direction perpendicular to the roof plane, for which the member 6 serves as car ⁇ rier, so as to ensure a certain mutual freedom of movemen in the vertical direction of the members 6 and 7 with respect to each other.
  • the connection be means of the bolt is so adapted that horizontal wind loads are sufficiently transmitted from the member 7 to the member 6.
  • auxiliary support members 7 do also allow a location of the frame works 3 at a considerably greater mutual distance than in industrial buildings previously known.
  • the traction member consists here of a rod which at its extremeties has heads 18 being arranged in clutches 12 attached to the beams and the auxiliary bearing members respectively without any possiblility to slip out thereof, by the fact that the heads have a greater transversal dimension than the openings of the clutches.
  • a stretching means 13, for example a stretching screw or the like, is arranged bet ⁇ ween a beam and the adjacent auxiliary bearing member 6 in order to stretch the traction member 11.
  • the vertical _ posi ⁇ tion of the auxiliary bearing member 6 may be adjusted and it will also be very easy to bring this member in alignment with the beams 5 and the mounting of the ar ⁇ rangement.
  • the traction members may have a second func ⁇ tion by serving as bearing members for laying of elec ⁇ trical cables and suspension of light fittings and other possible auxiliary equipment for the activities in the interior of the industrial building.
  • the roof frames may for example have more beams which support the beams 5, and in a frame work more than two beams 5 can be arranged side by side.
  • the beams 5 may of course also have the character of bay-work beams. It is not either required that the beams and the auxi ⁇ liary bearing members bear directly against the inner layer of the roof covering, but they can bear against secondary bearing means of the roof covering, such as other beams.
  • the roof covering and the wall covering must not either be designed in the way described but may have an arbitrary form.
  • auxiliary bearing members, the auxiliary support members, the pillars and the beams may just as well be constituted by hollow or solid beams or have any suitable form.
  • auxiliary bearing members for example weld the traction members to the roof co ⁇ vering supporting beams and the auxiliary bearing mem ⁇ bers.
  • One single traction member especially if it is a flexib one, for example a wire, may extend continuosly beyond several auxiliary bearing members 6 and beams 5. In that case one single stretching means would be enough for an initial stretching of the traction member, which at its both ends was secured to two beams 5, e_.g_..
  • traction member would run free with res ⁇ pect to auxiliary bearing members•-6 '" and possibly, further beams 5 located between these two ' beams'5 ' .
  • locking means for example a wire lock. This would simplify the mounting and make it possible to utilize cheap materials in the form of wire and wire lock.
  • trac tion members such as the ones 20 indicated by dashed " lines in fig 2, between the auxiliary bearing members 6 and the beams 5 in order to counteract lifting forces on the roof covering generated by wind.
  • These traction members should have their points of connection to the beams 5 located at a greater distance from the roof co ⁇ vering supporting plane than the points of connection to the auxiliary bearing members.
