Definitions

  • the invention relates to a steel construction system for the construction of building floors, especially floors with living rooms, work rooms or rooms for housing technical equipment, with the proviso that at least one floor construction and a ceiling construction are provided and the ceiling construction serves as a floor construction for another floor, said on the Floor structure supporting floor supports are placed, on which the ceiling construction rests, and wherein a connection system is provided, which connects each of the floor supports with the floor construction, and the connection system comprises a securing element for laterally fixing the floor support.
  • connection system that connects the floor support with a floor construction.
  • the connection system is provided with a securing element for lateral fixation of the floor support so that it can not be offset by a transverse load.
  • the floor support of a warehouse must not be displaced if a shock acts in the transverse direction, for example a load on a forklift against the floor support encounters.
  • connection system has an elastically sound-decoupling separating layer that the elastically sound-decoupling separating layer consists of soft elastic material, that the soft elastic material has a high resilience in deformation and low plastic long-term compression that the separation layer between the with the bottom construction connected fuse element and the floor support is arranged, and that the separating layer is both in the direction parallel to the floor support and in the radial direction to the floor support under constant pressure and compressed.
  • the floor supports and support beams of the floor and ceiling construction are made of steel.
  • the great advantage of the steel construction system according to the invention is seen in the fact that the steel components of the individual Bauwerksstockwerke are separated from each other by the separating layer of soft elastic material, in particular, is dispensed with a metallic connection by means of screws.
  • the structure-borne sound transmission is thereby prevented or drastically reduced, that the soft elastic material has a high resilience during deformation and a low plastic long-term compression.
  • Such a material is in the installed state under Continuous pressure of the building floor bearing thereon has a resonance frequency which does not exceed 15 Hz. Only by this technical measure has it become possible not to transmit the structure-borne sound occurring within a floor structure in an overlying or underlying Bauwerksstockwerk.
  • the separating layer of soft elastic material fulfills two functions. On the one hand, it decouples the underside of the floor support, which rests on the floor construction, from the floor construction. For this purpose, the separation layer is arranged in a horizontal plane between these two parts of the building. Secondly, the securing element serving for fixing the floor support laterally is decoupled elastically from the floor support substantially in the radial direction of the floor support. For this purpose, the soft elastic securing element is at least partially provided laterally with the separating layer, so that the floor support is only indirectly via the separating layer with the securing element in contact.
  • the soft elastic material of the separating layer has the property of an increased resonance frequency, the higher the continuous pressure through which the separating layer is compressed.
  • the highest continuous pressures are achieved on the horizontally disposed portion of the release liner which decouples the underside of the story support from the floor structure.
  • the entire building's floor or even several building blocks rest on the separating layer.
  • buildings with a low floor count can be built.
  • the sustainable load on the soft-elastic separating layer can be too high due to the weight of the structure and the interior.
  • the continuous pressure must not exceed a certain limit, in which the soft elastic material, for example, still has a resonant frequency of about 15 Hz. With resonance frequencies above the respective limit, the desired sound-insulating effect of the soft-elastic separating layer no longer achieved to the desired extent.
  • the resonant frequency to be achieved may be slightly higher because the transferable structure-borne noise can be tolerated. This can be the case, for example, in work rooms where an increased sound level prevails anyway.
  • a better material will be available that achieves the desired low resonance frequency at even higher steady-state pressures than the material currently available.
  • the steel construction system according to the invention also provides a particularly good electrical insulation and a complete heat insulation.
  • the steel construction system according to the invention includes release liner material of different qualities.
  • the release liner materials are classified into continuous load ranges for which they can be used. In the case of multi-storey construction, the material which, for example, at a required resonant frequency ⁇ 15 Hz, endures the continuous pressure of all the floors above it and interior furnishings must be used. The floor above is decoupled with a release liner material that achieves a resonant frequency ⁇ 15 Hz with less sustained pressure.
  • the different qualities of the release liner material may be marked in color or in writing to avoid confusion during assembly.
  • a steel construction system is created according to the modular principle, can be built very quickly with the Bauwerksstockwerke, especially floors with living rooms, work rooms or rooms for housing technical equipment.
  • the floor heights and spans between floor supports are also given in stages.
  • different sized separating layers are available in their geometry.
  • the proposed The steel construction system not only facilitates the erection of building floors but also facilitates building physics approvals because the structural evidence is cataloged and transferable from one construction project to another.
  • the floor supports have a closed tubular profile
  • the securing element of the connection system is conveniently designed as a safety pin and protrudes mounted on the floor construction securing pin in the clear opening of the upstanding on the floor structure floor support.
  • the mounting of the floor support is particularly simple because no additional connecting element, such as a screw connection, is required. Another benefit arises from the fact that all parts of the connection system in the assembled state are hidden within or below the floor support and for the further expansion and construction of the wall construction over the entire height of the floor a smooth tubular floor support is available.
  • the separating layer is designed as a hat-shaped separating element and has a separating rim in the manner of a hat brim, that the separating layer is placed on the securing mandrel and the separating ring of the separating layer between the front side of the floor support standing on the floor construction and the floor construction is arranged.
  • a hat-shaped, one-piece separating element for ease of use is appropriate.
  • a safety pin which has the shape of a truncated cone and a floor support, which is provided with a front-side centering, which via the intermediate Separating layer cooperates with the truncated cone of the securing mandrel.
  • This technical measure also facilitates the erection of the structure, because the truncated cone acts as a guide aid when setting up the floor support on the securing arbor.
  • the relatively heavy floor supports are usually positioned with a hoist above a connection point. An assembler, who has to guide the floor support by hand to the securing mandrel, facilitates the guide assistance the installation.
  • the steel construction system can be installed faster because of the guide.
  • the resultant in plan view annular projection surface of the cone receives a portion of the compressive load acting in the longitudinal direction of the floor support. In this way, the pressure load in the area of the separating layer arranged in the horizontal plane tends to be reduced. Along with this, the continuous pressure load and the resonance frequency of the separating layer decrease.
  • tubular profile of the floor support is filled with concrete.
  • the tubular floor support is thus taken the property of a sound body, which radiates sound after some kind of excitation as a sound box of a musical instrument.
  • a concrete-filled floor support increases the fire safety of the building. This is because the risk of falling with increasing temperature modulus of elasticity of the steel tube of the floor support is mitigated.
  • the concrete absorbs a considerable amount of heat in case of fire, which would otherwise raise the temperature of the floor support very quickly and would reduce the stability.
  • An alternative embodiment of the steel construction system may be one Have floor support with a solid rod or an open profile, wherein the fuse element with the interposition of the separating layer bears laterally from the outside of the floor support and is connected to the floor construction.
  • open profiles are T-beam, double T-beam or U-beam in question.
  • Such carriers may also be provided with concrete in their interstices.
  • Beams with open profiles are usually provided with flat and mutually perpendicular surfaces, so that wall elements, windows and other components can be used more easily than, for example, on floor supports with a round cross-section.
  • the soft elastic material of the release liner has a dynamic modulus of elasticity between 4 N / mm 2 and 8 N / mm 2 .
  • the soft-elastic material of the separating layer preferably consists of a foamed polyurethane with a closed-cell structure. It has been found that on the one hand this material has the required structural load-bearing capacities and, on the other hand, it is useful for its sound deadening due to its cell structure with gas-filled cells.
  • a foamed polyurethane having a cell scaffold which allows the high recovery of the release liner after deformation.
  • the internal pressure of the gas filling of the foam cells allows the resilience.
  • the resilience of such foams is very limited and have these much higher deformation residues after a pressure load. This is different with the proposed polyurethane foam. This receives, as mentioned, its resilience from the cell structure itself and therefore preserved under continuous load for a long time, its resilience and low resonance frequency almost unchanged.
  • an additional separating layer is arranged on the end of the floor support facing the ceiling construction, which causes a sound decoupling to the ceiling construction.
  • the floor support is thus sound-decoupled both at its end facing the floor construction via the connection system and at the end facing the ceiling construction by means of the additional separating layer.
  • a connection body pointing towards the floor construction is simply attached to the ceiling structure with which the ceiling construction rests on the floor support with the interposition of the additional separating layer.
  • the floor support is also fixed laterally at its end facing the ceiling construction, overlaps both the floor support and the additional separating layer attached to the ceiling structure connecting body.
  • connection system for sound-decoupled attachment of a floor support to a floor construction or a ceiling construction is proposed with a fastened to the floor construction or the ceiling structure securing element for lateral fixation of the floor support and a separating layer of soft elastic material, which has a high resilience in deformation and a low plastic Long-term compression has.
  • a connection point of a steel construction system 1 is shown enlarged. It is a floor support 2, which is connected at its end facing the floor 3 with the bottom structure 3. For connection, a sound-decoupling connection system 4 is provided.
  • the connection system 4 has a securing element 5, which is provided for the lateral fixation of the floor support 2 on the floor structure 3 and is connected by screws 6 fixed to the floor construction.
  • the connection system 4 has a frustoconical securing pin 7, which is provided with a fastening plate 8.
  • the mounting plate 8 is provided with holes 9 for receiving the screws 6, with which the securing element 5 is fixed to the floor structure 3.
  • the securing mandrel 7 and the attachment plate 8 are enveloped in deformation by a separating layer made of flexible material with a high recovery capacity and designed as a hat-shaped separating element 10.
  • the separating element 10 has a separating rim 10a in the manner of a hat brim extending in the horizontal plane of the floor construction and sound-decoupling it from the front side of the upstanding floor support 2.
  • the voltage applied to the truncated conical securing mandrel 7 area 10 b of the separating element 10 is in contact with a cup-shaped centering receptacle 2 b, which sits in the clear opening of the story support 2. It is adapted to the shape of the safety pin 7 and firmly connected to the pipe wall of the floor support 2. In this way, the floor support 2 is both fixed laterally, and sound-decoupled from the connected to the bottom structure 3 securing mandrel 7 in the radial direction.
  • the centering receptacle 2b also hugs one side of the separating element 10, like the securing mandrel 7 on the opposite side of the separating element 10.
  • the centering receptacle 2b forms a floor within the storey support 2, up to which the concrete filling 2a reaches.
  • the provided with a centering 2b embodiment of a story support 2 is advantageously prefabricated together with the concrete filling 2a. During assembly on the construction site then no fresh concrete must be processed, which reduces the assembly time.
  • a concrete-filled floor support 2 is constructed without a bottom in the form of a centering 2b. Because of the lack of soil of the concrete 2a is in direct contact with the separator 10, which is easy to understand with reference to FIG. In order to achieve a good contact, the floor support 2 is initially set up empty without concrete filling. Only then, when the floor support 2 is placed over the securing mandrel 7, a filling 2a of fresh dehulless, swellable fine concrete is filled. The fine concrete binds in the predetermined by the securing mandrel 7 and the separator 10 shape and offers in the hardened state centering and good power transmission between the floor construction 3 and the floor support second
  • floor construction 3 consists essentially of a support beam 11 to which the mounting plate 8 of the securing mandrel 7 is screwed from a resting on the support beam 11 trapezoidal sheet 12, which is filled with concrete 13.
  • the floor support 2 is provided with a casing 14 which inter alia for the purpose of corrosion protection prevents direct contact of the concrete 13 with the steel pipe of the floor support 2.
  • connection system 4 is hidden within the floor structure 3. Only the smooth surface of floor support 2 is visible. At this non-load-bearing wall constructions can be attached.
  • Fig. 2 shows a perspective view of a support beam 11, on which a securing element 5 is mounted for lateral fixation of a floor support. It is in the support beam 11 is a double-T-carrier.
  • the securing element 5 has a frustoconical securing mandrel 7, on whose large cylindrical base a fixing lath 8 is attached. The latter in turn is screwed to the carrier beam 11 with screw connections (not shown).
  • a ceiling construction 30 For the sake of simplicity, only one support beam 22 is represented by the ceiling construction 30. At the latter, a connecting body 23 for a floor support 2 is welded so as to protrude in the direction of the floor structure. In the clear opening of the floor support 2, a recessed floor 24 is welded, which serves as a support for the connecting body 23 of the ceiling structure 30.
  • the separating layer 21 is between the connecting body 23 and the bottom 24 of the floor support 2 laid. For lateral fixation of the floor support 2, both the floor support 2 and the separating layer 21 overlap the connecting body 23 of the ceiling structure 30.
  • the sound insulation of a floor can be either additionally improved or it can be used as a substitute if a sound decoupling of the floor supports on the floor construction for technical reasons is not feasible.
  • a sound decoupling of the floor supports only on the ceiling construction is less effective than on the floor construction.
  • a floor support can therefore be sound-decoupled both at one of its two ends or at both ends at the same time.
  • the sound decoupling in the area of the floor construction 3 is the most effective individual measure. This is because structure-borne noise is usually created by movements on the floor construction 3 and the structure-borne noise is reduced in this way close to the place of origin.
  • a sound decoupling at the end of the floor support 2 facing the ceiling construction 30 is then considered as an optional measure if a particularly good sound decoupling is desired.
  • FIG. 4 shows a perspective view of a support beam 22 of a ceiling construction 30 according to FIG. 3.
  • the support beam 22 is in turn a double-T support to which a cylindrical connection body 23 pointing downwards to the floor construction is welded.
