Definitions

  • the invention relates to a suspension system for a framework structure, a method for suspending a framework structure on an exterior wall structure of a building and the use of such suspension system.
  • the framework structures may either be integrally formed with the building or be provided as pre-formed modules that are mounted to the exterior wall structure of the building.
  • the latter may be made by providing the exterior wall structure of the building with a plurality of beams that project out from the wall structure and further providing a framework module which comprises a plurality of apertures to be aligned with the longitudinal extension of the respective beams.
  • the framework module is mounted to the beams by inserting the beams into their respective apertures in the framework module. Hence, in other words, the framework module is slid onto the beams. In the resulting installation, the weight of the framework structure will be supported by the beams.
  • the installation Since the installation is arranged in an elevated position in view of the ground it is essential that the work of suspending the framework module as such may be made as easy as possible. Any angular misalignment of the beams, even a small one as measured close to the wall structure, will cause a substantial angular misalignment as seen at the free ends of the beams. Such angular misalignment may cause a so-called drawer effect which makes it more difficult to insert the beams into corresponding openings in a framework module.
  • the suspension work is made by one or more cranes, which requires a highly skilled personnel due to the overall small tolerances, heights and weights. An installation of this type typically also involves a substantial cost in terms of machinery since at least one crane must be allocated. Thus, it is essential that the installation time may be reduced.
  • the following levelling of the suspended framework module may be made in an easy manner to ensure that e.g. a flooring of a finished balcony will be horizontal. Further, since the overall visual appearance of the building with the framework structures is of essence, there is a strive towards framework structures where beams, fastening elements etc. are concealed to as large extent as possible.
  • the main object of the invention is to provide a system allowing an easy suspension of a framework structure to a building.
  • Another object is to provide a system that allows an easy suspension and levelling of a framework structure.
  • suspension system should be applicable no matter if it is a mounting that is made during a new construction of a building or as a retrofit.
  • a suspension system for a framework structure comprising: a plurality of beams having a longitudinal extension, each beam being configured to be directly or indirectly mounted on an exterior wall structure of a building; and a framework, the framework comprising a plurality of guiding rails, wherein the framework is configured to be mounted to the plurality of beams by longitudinally inserting the plurality of beams into a respective guiding rail; wherein each beam has an outer beam width, and wherein one specific guiding rail of the plurality of guiding rails has a first inner guiding rail width, and the remaining guiding rails of the plurality of guiding rails have a second inner guiding rail width, the first inner guiding rail width being smaller than the second inner guiding rail width and larger than the outer beam width.
  • a suspension system for a framework structure where a framework is provided which comprises a plurality of guiding rails, each guiding rail being configured to receive a beam to be inserted into the guiding rail.
  • the framework module is slid onto the beams.
  • One specific guiding rail has an inner width that is smaller than inner width of the other guiding rails but larger than the outer width of plurality of beams.
  • Each guiding rail may comprise a top wall and two opposing side walls, the top wall and the side walls having a longitudinal extension configured to coincide with the longitudinal extension of a respective beam, said top wall having a continuous or discontinuous extension as seen transverse to the longitudinal extension.
  • the guiding rail may be provided by two extruded longitudinally extending profiles, each having a L-shaped cross-section.
  • the guiding rail may be provided by an extruded longitudinally extending profile having a U- shaped cross section. Two L-shaped profiles may even be preferred as compared to a single U-shaped profile since the weight of the guiding rails and hence the overall weight of the framework may be reduced.
  • each guiding rail may comprise at least two adjusting bolts, each bolt having a free end configured to abut a top wall of a respective beam, thereby allowing levelling of the framework by adjusting the at least two adjusting bolts.
  • the framework will be either lifted or lowered in view of the beams which as such are fixedly mounted to the building.
  • the framework, and hence any flooring to be arranged thereon, may be horizontally levelled.
  • the plurality of guiding rails may be ordered in a parallel relationship in view of each other, such that the specific guiding rail is centrally located among the plurality of guiding rails.
  • At least one guiding rail of the plurality of guiding rails may comprise two profiles, each profile having an L-shaped cross-section.
  • the two profiles may be connected by a plurality of transversally extending coupling members.
  • One or more of said coupling members may be provided with a through-going hole configured to threadingly receive an adjusting bolt.
  • At least one guiding rail of the plurality of guiding rails may in one embodiment comprise a U-shaped cross-sectional profile.
  • the web of said U-shaped cross-sectional profile may be provided with at least two through-going holes, each hole being configured to threadingly receive an adjusting bolt.
  • At least one guiding rail of the plurality of guiding rails may have a straight longitudinal extension or a tapered longitudinal extension.
  • a tapered longitudinal extension facilitates guiding of the framework in view of the beams.
  • At least one guiding rail of the plurality of guiding rails may in one embodiment comprise a hollow quadrangular cross-sectional profile.
  • a top wall of said hollow quadrangular cross-sectional profile may be provided with at least two through-going holes, each hole being configured to threadingly receive an adjusting bolt.
  • the plurality of guiding rails may comprise a combination of an L-shaped profile, a U-shaped profile and a hollow quadrangular cross-sectional profile.
  • the at least two adjusting bolts may be threadingly received in a respective member forming part of the framework.
  • the suspension system may further comprise at least one bracket configured to clamp the framework into a firm engagement with the plurality of beams.
  • Each beam may in one embodiment comprise: a first support being configured to be mounted on the exterior wall structure of the building, said first support, in a free end thereof facing away from the building, comprising an end plate supporting a projection, and a second support being configured to be mounted to the framework, said second support comprising a rear end configured to face the exterior wall structure of the building and a front end configured to be longitudinally inserted in a respective guiding rail of the framework, and the rear end of the second support comprises a locking plate, said locking plate comprising an opening configured to receive the projection of the end plate of the first support, thereby lockingly engaging the first and the second supports.
  • each beam comprises: a first support being configured to be mounted on wall structure of the building, said first support, in a free end thereof facing away from the building, comprising an end plate comprising an opening, and a second support being configured to be mounted to the framework, said second support comprising a rear end configured to face the exterior wall structure of the building and a front end configured to be longitudinally inserted in a respective guiding rail of the framework, and wherein the rear end of the second support comprises a locking plate, said locking plate comprising projection configured to be inserted into the opening of the end plate of the first support, thereby lockingly engaging the first and the second supports.
  • the respective beam may be divided into two sections - the first support and the second support.
  • the first support is configured to be fixedly mounted to the exterior wall structure of the building.
  • the second support is configured to be mounted to the first support by the locking plate of the second support directly, or indirectly lockingly engaging the end plate of the first support.
  • the second support will thereby constitute the beam which is configured to be inserted into a guiding rail of the framework.
  • the mounting of the beam to the building will be substantially facilitated. Since the beam is typically mounted to the building by means of casting concrete in the event of a new construction, by bolting, or by inserting rebars in drilled holes in an existing wall structure, it is easier to handle a smaller sub-element, i.e. the first support, during fixation of the beam to the wall structure as such, both in terms of volume and weight.
  • the first support is properly fixated to the wall structure
  • the second support may be mounted to the first support to thereby form the beam to which the framework is to be suspended.
  • the division of the beam into two sections facilitates a proper alignment of the first support in the horizontal and vertical direction in view of the wall structure before fixation and before mounting the second support thereto. Further, the division of the beam into two supports facilitates scaffolding since the first support typically can be substantially shorter than the second support, which second support can be mounted in connection to the installation of the framework.
  • any remaining angular errors between the extension of the first support in view of the wall structure may be compensated for by adjusting the second support in view of the first support before mounting the framework to the resulting beam.
  • the adjustment of the second support in view of the first support may be made by one or more adjusting bolts which may be arranged to act between the end plate of the first support and the locking plate of the second support. Accordingly, the division of the beam into two supports will allow improved possibilities of correction of angular errors which may cause problems during suspension of the framework when the plurality of beams should be inserted into the plurality of guiding rails of the framework.
  • the locking plate may comprise a first adjusting bolt and a second adjusting bolt, said adjusting bolts being arranged on opposite sides of a longitudinal center line of the locking plate, wherein said bolts are threadingly received by threading in through-going bores in the locking plate, and wherein a free end of the respective adjusting bolt is configured to abut the end plate of the first support in a condition when the second support is connected to the first support.
  • the adjusting bolts may allow adjusting a direction of the second support in the horizontal plane and in the vertical plane prior to mounting the framework to the resulting beam.
  • the adjustment is made in order to ensure that the top surface of the framework will be levelled, i.e. have a horizontal extension.
  • the framework is configured to be suspended by a plurality of beams, it is essential that all beams are properly arranged in a parallel relationship. This adjustment may as well be made by the two adjusting bolts of each beam. Accordingly, by providing the locking plate with two adjusting bolts, an effect corresponding to a ball joint may be achieved.
  • a method for suspending a framework on an exterior wall structure of a building comprises the following steps: mounting a plurality of beams, directly or indirectly, to an exterior wall structure of a building, each beam having a longitudinal extension, and each beam having an outer beam width; providing a framework, the framework comprising a plurality of guiding rails, each guiding rail comprising a top wall and two opposing side walls, the top wall and the side walls having a longitudinal extension coinciding with the longitudinal extension of a respective beam, and one specific guiding rail of the plurality of guiding rails having a first inner guiding rail width, and the remaining guiding rails of the plurality of guiding rails having a second inner guiding rail width, the first inner guiding rail width being smaller than the second inner guiding rail width and being larger than the outer beam width; and longitudinally inserting the plurality of beams into a respective guiding rail of the framework.
  • the advantages with a suspension system using such combination of beams and framework have been thoroughly discussed above.
  • the advantages are equally applicable to a method which involves the use of such suspension system.
  • the specific guiding rail with the smaller inner width will act as a guide that linearly controls the relative displacement between the complete framework and the plurality of beams while at the same time reducing or even preventing any drawer effect i.e. any misalignment between the beams and the inner walls of the guiding rails, which may cause an unwanted frictional locking engagement.
  • a simplified and faster suspension process is provided for, and also an overall safer working environment is provided for since the amount of manual hands-on work may be reduced. This applies no matter if the suspension is made during the erection of a new building or as a retrofitting to an existing building.

  • the next step is to level the framework 200 in the horizontal direction. This is made by setting the plurality of adjusting bolts 202 which are supported by the plurality guiding rails 201. By setting, i.e. by screwing, the individual adjusting bolts 202, the free end 217 of the respective adjusting bolt 202 will engage the outer top wall 118 of the respective beam 100 and thereby either lift or lower the framework 200 until a complete levelling in the horizontal direction is achieved.
  • the framework 200 of the balcony may be provided with at least one bracket 218 that is configured to clamp the framework 200 into a firm engagement with the beams 100.
  • bracket 218 is disclosed in Figs. 10a and 10b.
  • the bracket 218 has a U-shape with a web 219 which interconnects two legs 220.
  • Each leg 220 comprises a vertically extending groove 221 with a fixed nut 222.
  • the bracket 218 straddles the lower side of the beam 100.
  • the bracket 218 is supported by a lower side of the connecting beam 207 of the framework 200 of the balcony by two bolts 223 on opposite sides of the beam 100.
  • the two bolts 223 threadingly engage a respective nut 222 of the bracket 218.
  • bracket 218 By setting the bolts 223, the bracket 218 will move upwardly, see Fig. 10b, into a position where the web 219 of the bracket 218 forces the beam 100 upwardly in the vertical direction into a firm engagement with the free end 218 of the adjusting bolt 202. Thereby, the framework 200 will be effectively locked to the beams 100 and hence indirectly to the wall structure 500 of the building.
  • the corresponding locking function may be provided for in a number of ways within the scope of the invention. Accordingly, the disclosed embodiment of the bracket 218 is one of many possible. Further, the number of brackets 218 may be one or more.
  • the top wall 203 of the framework 200 may be provided with a suitable flooring such as tiles 400 or boards, see Fig. 1 .
  • the framework 200 should preferably be provided with any covering plates 205 and also, the peripheral outer edge of the framework 200 of the balcony should be provided with a protective a balcony railing 206.
  • the respective beam 100 is divided into two sections - the first support 101 and the second support 102.
  • the first support 101 is configured to be fixedly mounted to the wall structure 500 of the building and the second support 102 is configured to be adjustably mounted to the first support 101.
  • the mounting of the beam 100 to the building will be substantially facilitated. Since the beam 100 is typically mounted to the building by means of casting concrete it is easier to handle a smaller sub-element, both in terms of volume and weight. This facilitate a proper alignment of the first support 101 in view of the building wall before mounting the second support 102 to the first support 101.
  • any angular errors between the extension of the first support 101 in view of the building may be compensated for by adjusting the second support 102 in view of the first support 101 by using the adjusting bolts 117a, 117b. This may be made for each beam 100 before mounting the framework 200 to the beams 100. Also, the longitudinal extensions of the second supports 102 of the plurality of beams 100 may be adjusted so that all second supports 102 extend in parallel to each other before mounting the framework 200 to the beams 100. Thus, the division of the beam in two supports allows a “bi-directional” adjustment of the beam which contributes to a reduction or even elimination of any drawer effect during mounting of the framework 200 to the beams 100.
  • the framework 200 is configured to be mounted to the beams by inserting the plurality of beams into the corresponding plurality of guiding rails in the framework 200. This is made by a sliding movement. Since one specific guiding rail 201a has a smaller inner width WG1 than the other guiding rails 201b-201e, any drawer effect i.e. any misalignment between the beams 100 and the inner walls of the guiding rails 201 causing a frictional locking engagement, may be effectively reduced or even avoided. Thus, by the present invention, a simplified and faster suspension process is provided for and also an overall safer working environment is provided for since the amount of manual hands-on work may be reduced. This applies no matter if the suspension is made during the erection of a new building or as a retrofitting to an existing building.
  • the guiding rails have been illustrated as being formed by two longitudinally extending L-shaped profiles. The skilled person realizes that other designs are possible within the scope of the invention.
  • One or more of the guiding rails may be formed by a longitudinally extending extruded profile having a U-shaped cross- section or a hollow quadrangular cross-section.
  • the web of such U-shaped cross-sectional profile may be provided with a plurality of through-going holes, each hole being configured to threadingly receive an adjusting bolt.
  • the top wall of such profile may be provided with a plurality of through-going holes, each hole being configured to threadingly receive an adjusting bolt.
  • the plurality of guiding rails may comprise a combination of an L-shaped profile, a U-shaped profile and a quadrangular profile.
  • At least one guiding rail of the plurality of guiding rails may have a straight longitudinal extension or a tapered longitudinal extension.
  • openings of the respective guiding rails have been illustrated as being aligned with each other and aligned with a rear end surface of the framework, it is to be understood that they may be mutually displaced in view of each other and/or be longitudinally displaced in the width direction in view of the rear end surface of the framework of the balcony.
