Definitions

  • the invention relates to a method for increasing the height distance of a roof structure from the top floor of a building according to the preamble of claim 1, and devices for performing the method.
  • the lifting units are then secured by blocking the telescopic supports and steel cables are tensioned by winches, which engage on rods running along the long sides of the building and connected to the rafters. After the outer walls have been bricked up, the procedure is reversed and the entablature placed on new purlins.
  • reliable guidance of the roof truss is not ensured during the lifting process, since the telescopic supports extending obliquely in the longitudinal direction of the roof truss are unable to absorb forces acting transversely to the longitudinal direction, for example wind forces.
  • the steel cables cannot contribute to this, since they are flexible and at best can prevent the roof truss from lifting.
  • the lifting units remain in the roof structure until the outer walls are walled up, on the one hand they hinder the loft conversion and on the other hand they cannot be used for any other use. Even if the lifting units were removed, they could not be used because the shoes and the lower supports on which the lifting units are supported also serve to support the telescopic supports. There is also no possibility mentioned of how the raised roof structure can be aligned, which has proven to be necessary in most cases. Finally, the known method is also more expensive due to the provision of steel cables which are to be tensioned by winds and cannot be used for lifting roof trusses of multi-storey houses.
  • the roof truss By actuating the lifting units, the roof truss is raised and guided through the telescopic supports, which are blocked after the lifting process has ended, whereupon the lifting units can be removed.
  • the horizontal beams of the truss are penetrated by the telescopic supports and thereby weakened.
  • very long telescopic supports and lifting units which are expensive due to their length and have little stability, are required when the height of the ground floor is retracted.
  • This method is also extremely expensive and unrealistic in that the telescopic supports must be provided when the building is erected.
  • This method is made more expensive by the fact that the roof truss has to be designed as a self-supporting unit with additional longitudinal purlins located outside the building, on which the lifting units later attack. For The addition of this method is unthinkable if a multi-story building or a brick building is to be added to.
  • US-A-4 980 999 describes a roof lifting system in which middle and side auxiliary purlins protruding from the roof truss are drawn into the roof truss and vertical columns are attached to the outer walls of the building which are located on the floor Support and protrude the roof structure according to the desired lifting height.
  • Lifting units in the form of pulley blocks or lifting cylinders are attached to the columns, which act on the protruding ends of the auxiliary purlins.
  • This system is extremely complex because it requires a large number of long columns that have to be connected very securely to the outer walls of the building and anchored in the ground. In multi-storey buildings, this system is practically not applicable due to the large length of the pillars then required.
  • the invention has for its object to provide a method of the generic type, which can be used at any time regardless of the height and nature of the structure and with which an alignment of the raised roof truss enables reliable guidance of the roof truss achieved during lifting and the economy the procedure is increased.
  • the method can be carried out quickly and the raised roof structure can be adjusted in a simple manner by corresponding actuation of individual lifting units or groups of lifting units.
  • the lifting units Due to the expansion of the lifting units, which can usually also be arranged in the middle of the attic, the area under the roof is again largely unhindered, which considerably simplifies and speeds up the roof expansion.
  • the economic viability of the method is further increased by the fact that the guide assemblies remain in the blocked state as structural elements in the building. On the one hand, this strengthens the connection between the raised roof truss and the structure and, on the other hand, it saves the effort of removing the guide units.
  • the lifting process is independent of the roof construction and shape, the roof covering, the length of the roof, the nature of the attic and the height of the building.
  • the guide units are preferably arranged on both long sides of the roof truss near the outer walls of the building. With this arrangement, the guide units do not interfere with the roof extension after the lifting units have been removed.
  • auxiliary purlins running in the longitudinal direction before lifting, via which the lifting forces are transmitted to the roof structure.
  • a medium auxiliary purlin and, symmetrically thereto, at least two lateral auxiliary purlins are located below the ridge provided for about medium rafter length.
  • the middle auxiliary purlins which are outside the area required for the loft extension, can be permanently connected with ridge pliers, which permanently strengthens the roof structure, while the lateral auxiliary purlins are detachably but preferably articulatedly connected to individual roof rafters.
  • First selected rafters are provided with spherical bearings that are aligned in height, whereupon the lateral auxiliary purlins picked up on lifting units are brought into engagement with the spherical bearings.
  • the guide units for the roof structure have vertical columns which can be attached to the building and means for connecting the columns to the roof structure.
  • these known columns are designed as telescopic supports, of which the lower part is attached to the building and the upper part to the roof structure.
  • Such telescopic supports are expensive and increase the costs considerably if they remain in the roof structure.
  • telescopic columns are not very stable when they are fully extended.
  • the columns are made in one piece and in encompassing guide brackets, means being provided for connecting the columns to their guide bracket or to the relevant rafters, so that the column can be fixed relative to the roof truss after the lifting and adjusting process.
  • Such guide units represent simple and inexpensive parts that can remain in the building as lost components. They have the further advantage that, in contrast to telescopic guide assemblies, their stability is the same over the entire guide height due to the one-piece design of the columns. A risk of wobbling and the associated risk of buckling are therefore not to be feared.
  • the columns protruding upwards from the roof truss before lifting can, if necessary, be simply cut flush with the roof truss after lifting, making it possible to provide certain standard lengths for the columns.
  • the adaptation to the individual case is then carried out by means of the capping process.
  • the swivel axis between the upper and lower part is to the longitudinal central axis of the auxiliary purlins laterally offset and the torque that occurs when the lifting unit acting on the auxiliary purlins is extended is to be absorbed by a clamping screw which fixes the lower part relative to the upper part.
  • This version is not only complex in terms of assembly, since it requires the upper part to be clamped to the rafters and the lower part to be fixed relative to the upper part, but also unsafe, since if the clamping screws are insufficiently tightened, the lower part can pivot relative to the upper part when the lifting unit is extended, which means that the piston of the lifting unit is exposed to considerable lateral forces and in extreme cases the lifting unit can buckle.
  • the roof truss 1 shown in FIG. 1 initially rests, as shown on the left half of FIG. 1, on a floor extension 3 which does not protrude, or only slightly protrudes, from the uppermost floor ceiling 2 of an assigned building. In the present example, this is to be increased to enable a loft extension , as indicated on the right half of Fig. 1 by a knee stick 4 shown with broken lines. For this purpose, the existing roof truss 1 is removed from the floor approach 3 and raised by a corresponding amount.
  • a lifting device which will be described in more detail below, is used to lift the roof structure 1 and is first brought into position. Then the anchoring of the roof truss 1 to the building, for example in the form of the roof truss 1 with the projecting shoulder 3, is released. Likewise, all permanently installed connections such as chimney surrounds, gutters, downpipes, electrical lines and the like are dismantled or extended. The roof truss 1 is then lifted as a whole in the assembled state and in the roof covering left in place. In the example shown, the roof structure 1 is first raised and then held in the raised position so that the knee stick 4 can be pulled up. As soon as this is the case, the roof structure 1 can be anchored on the knee stick 4. To relocate the roof structure during the lifting process or in the raised position To avoid 1 transversely to the lifting direction, the roof truss 1 is guided in the vertical lifting direction and left in engagement with the guide at least until it is received on the raised knee stick 4.
  • the number of lifting units 6 used depends on the type and size of the roof structure. In any case, such a number is provided that the roof truss 1 can be raised evenly in the assembled state.
  • the lifting units 6 are placed in such a way that the stress on the roof truss 1 is as uniform as possible. For roof trusses of normal design, it is sufficient if the lifting units are placed at a distance of three to five rafters.
  • the lifting units can engage on the beams running transversely to the rafters, as here on the ridge beam 8 or the roof purlins 9 running parallel thereto. A direct attack on individual rafters is also conceivable. In these cases, a wedge-like attack console 10 can be attached.
  • the hydraulic lifting units 6 are connected to a pressure source by pressure lines 11.
  • the entire pressure generating device is preferably placed on the top floor ceiling 2, but can also be arranged outside the building.
  • the lifting process is carried out in several stages.
  • the roof structure 1 is brought to the desired height in the course of a rough stroke.
  • all lifting units are put into operation together, which is accomplished by a control device 16 assigned to the distribution station 15.
  • the roof structure 1 is aligned, which is accomplished by commissioning individual lifting units or groups of lifting units.
  • manually operated switching valves 17 are provided in the pressure lines 11.
  • the adjustment movement is expediently carried out in a slower gear than the rough stroke movement.
  • the basic position of the lifting units with retracted piston rods is shown in the left half of the drawing, the end position with extended piston rods in the right half of the drawing.
  • guide units 18 are provided which are provided with guide surfaces running in the stroke direction.
  • These guide units 18 are designed here as telescopic telescopes, the stationary lower part 19 of which can be fixed on the building, here on the top floor ceiling 2, as indicated by screws 20, and whose upper part 21 guided in the lower part can be fixed with its upper end on the roof frame 1 , as is indicated here by a holding shoe 22 which can be screwed to the roof structure 1.
  • the guide units 18 are without a drive. Their upper parts 21 are extended from their lower parts 19 when the roof structure 1 is raised.
  • the guide assemblies 18, which can be set up independently of one another, are provided in such a number that the transverse forces which occur are absorbed. For this purpose, it is usually sufficient if guide units are provided in the area of every second rafter.
  • rigid steel supports 23 can be used in addition to the lifting units, if necessary.
  • This can be one-part supports or two-part supports provided with an adjusting thread in a manner known per se.
  • the lifting units 6 can be retracted and removed.
  • the roof truss 1 then rests on the supports 23.
  • the guide assemblies 18 remain in position to prevent that on the Supports 23 resting roof truss 1 can move transversely to the lifting direction.
  • the upper and lower parts of the guide units 18 could, however, also be locked against one another, for example by means of pins etc., so that they serve as rigid supports. In this case, the supports 23 can be omitted.
  • the lifting units 6 can now be dismantled together with the associated pressure generating device and used for further use on a new construction site. Now the knee stick 4 is pulled up and the roof truss 1 is anchored thereon.
  • the telescopes 18 provided as guide units in the example according to FIG. 1 are relatively expensive, so that leaving them in the raised roof structure is uneconomical.
  • guide units 18a which are much cheaper are used to guide the roof structure 1 during lifting or lowering, each of which has one on the floor ceiling 2 have anchored vertical column 24 which interacts with a guide bracket 25 which can be fixed on the roof structure 1.
  • the guide units 18a are placed in the lower roof truss area, ie in the knee stick area.
  • the number of guide units 18a used is selected so that the anticipated transverse forces can be absorbed. As a rule, it is sufficient if a guide unit 18a is assigned to every third rafters 1a.
  • Each vertical column 24 is received on a foot 26 which is anchored to the floor ceiling 2.
  • the column 24 can be designed as a rectangular tube section, but can also have a different cross section.
  • the foot 26 can be formed by a rectangular plate which is provided with holes 27 for receiving fastening screws.
  • the foot 26 is placed on the raw concrete of the floor ceiling 2 and aligned so that the column 24 is vertical.
  • the screed of the floor ceiling 2 is removed at the points in question and the exposed concrete surface is leveled with leveling compound.
  • the screws assigned to the holes 27 can then be set, to which the foot 26 is then anchored.
  • the plate forming the foot 26 is provided with webs 28 flanking the column 24.
  • These can be designed as symmetrically arranged U-rail sections which receive the column 24 between them, which are welded to the column 24 and to the foot 26 or are connected in some other way.
  • the columns 24 are, as shown in FIGS. 2 and 3, mounted so that they rest with the flank of their rectangular cross section on the side flank of a respective rafter 1a.
  • the guide bracket 25 are attached to the relevant rafters 1a.
  • the guide brackets 25 have a central U-shaped pocket 25a and fastening tabs 25b projecting laterally therefrom.
  • the pocket 25a has an internal width corresponding to the outer dimensions of the cross section of the assigned column 24 plus running play.
  • Each guide bracket 25 is attached with its fastening lugs 25b to the associated rafters la and thus, together with this, delimits a guide channel through which the column extends.
  • the holding tabs 25b are fastened to the rafters la by nails or screws and are provided with corresponding holes 25c for this purpose.
  • a further bore 25d is provided, by means of which pinning or screwing between the guide bracket and the associated column is possible.
  • the columns 24 initially protrude beyond the roof structure 1 by at least the length corresponding to the lifting height.
  • the roof is opened at the relevant points.
  • the length of the columns 24 thus corresponds at least to the original distance of the Rafter top from the floor ceiling 2 in the area of the associated guide bracket 25 plus the desired lifting dimension.
  • the guide brackets 25, as already mentioned, are connected to the respectively assigned column 24.
  • the columns 24 are each provided with a bore aligned with the bore 25d of the associated guide bracket 25, so that a plug pin or a screw can be inserted. In this way, the guide units 18a become rigid support elements.
  • the columns 24 can also be connected directly to the associated rafters.
  • the protruding piece 24a (FIG. 3) is simply cut off flush with the top of the roof truss. This enables the use of standardized column lengths. After the columns 24 have been shortened accordingly, the roof is closed again.

  • the support heads 35a, 35b each consist, as can best be seen from FIG. 9, of a base plate 36 with projections 37 projecting vertically upward therefrom, which delimit a channel 38, the inside width of which corresponds to the width of the auxiliary greases 31.
  • the projections 37 are designed as angular profile sections placed on the base plate 36.
  • the support heads 35a, 35b are brought into engagement with the respective associated auxiliary purlin 30 or 31 in such a way that it engages in the channel 38, as indicated by broken lines in FIG. 9.
