    ROOF CHAIR STRUCTURE FOR UPPER FLOOR STRUCTURE WITH INSULATION
    The invention relates to a roof truss structure for an upper floor structure of a building, in which the insulation is a depressing blow insulation and the roof chair structure comprises - a lower girder, an upper girder and beams between them, almost all parts of which are inclined.
    The roof truss is the supporting structure of the building's water roof. During construction, roof trusses are attached to the walls of the building and roof structures and roofing material are attached to the roof trusses.
    A few - decades ago - a combination of sloping beamed roof trusses and recessed blown insulation was introduced as the upper floor structure, which is still the prevailing practice. In this structure, the load-bearing capacity of the roof trusses is based on the fact that most of the rafters' beams in the structure are inclined in a vertical position, resulting in less material - roof trusses that meet the strength requirements and have increased spans and no longer need to be supported. As insulation, easier and faster to install and also cheaper blown wool was introduced, which was used to better insulate even tight spaces, including the undersides of sloping beams, which were really difficult to insulate tightly with piece insulation.
    After fixing the roof trusses and usually after making the roof, thermal insulation of the upper floor is installed in the building. When a loose insulating material, such as blown wool, is used for insulation, the insulating material is blown and applied to the top base in an even layer. When blowing wool is applied, it also goes into the gaps in the roof truss structure. After application, the loose O 25 thermal insulation material is on the same level on both sides of the roof trusses.
    S Loose thermal insulation material, such as blown wool, is not a solid material, but consists of large and small, suitably treated fibers or the like, which together form a thermal insulation layer. This kind of material - spreads easily and can be blown well into the target. Over time, such a 3 O 30 8 5corrosive material condenses, i.e. it is pushed downwards due to the vibration, humidity and gravity of the building.
    Although the thermal insulation material is depressed downwards, its fibers have adhered to each other and can no longer move laterally at this stage.
    Thus, the properties of the thermal insulation material deteriorate when cold bridges are formed under the sloping beams of the roof trusses due to the depression due to the properties of the insulation.
    However, this important issue was completely overlooked when designing the top floor structure to be done with sloping beam roof trusses and depressed blow insulation.
    This structure poses a compatibility problem with the upper floor because the depression inherent in the properties of the blown insulation causes cold bridge tunnels below the sloping beams of the roof truss, which complicates the energy and moisture technical operation of the upper floor.
    The deflection is taken into account in the guidelines of the Ministry of the Environment with a call to blow the deflection a little more to reach — the target strength.
    This instruction only takes into account the depression at the top of the insulation, it does not take into account that cold bridge tunnels are automatically formed below the sloping beams of the roof truss.
    The cold bridge tunnels created in the thermal insulation layer from the nail plate to the surface of the blown insulation increase energy consumption.
    In addition, heat condenses into moisture at these points, which can - cause a moisture and mold problem.
    In the roof truss structure according to the invention, the upper surface of the lower beam is raised up to the upper surface of the non-depressed blow insulation, whereby the blow insulation presses along the vertical sides of the lower beam, whereby no cold bridges are created in the upper bottom structure.
    Such high beams have been used as a lower beam for various purposes 2 25 - also in the past, when their purpose was to increase the load-bearing capacity of the structure.
    N In the roof truss structure according to the invention, the lower girder is raised for a different purpose.
    In the roof truss structure according to the invention, the lower girder is - raised to the surface of the non-depressed blow insulation because the insulation I presses directly downwards along the vertical sides of the lower girder. a 3 30 S This eliminates the compatibility problem and the N cold bridges in the upper floor structure due to the depression of the blown insulation and improves its energy and moisture technical performance.
    3 | It is an object of the invention to provide a roof truss structure which eliminates the compatibility problems associated with existing top floor structures. In particular, it is an object of the invention to provide a roof truss structure with which a blow insulation layer | the cold bridge tunnels are removed from the upper bottom structure and prevent energy loss and the risk of moisture and mold damage. In addition, the present invention is to provide a kattoristikkorakenne, wherein palaeristeellä Isolation is facilitated when the pattern in a blow insulation is not a diagonal beams to the underside of the isolation palaeristeellä has previously been difficult. It is also an object of the invention to provide a roof truss structure in which it is easy to make access bridges on a raised lower beam.
    The object of the invention is achieved by a roof truss structure which is characterized by what is stated in the protection requirements.
    The roof truss structure according to the invention is = characterized, = that the lower beams inside the depressed blow insulation of the roof truss structure are raised up to the surface of the non-depressed insulation. In the truss structure above the insulation, the beams are in an oblique position to ensure that the strength requirements of the roof trusses are met. When the depressed blow insulation is pressed - along the surfaces of the raised lower beams, the formation of cold bridges in the upper bottom structure is prevented. Such a roof truss structure removes cold bridges from the top floor structure and reduces the risk of moisture and mold damage, improving its energy and moisture engineering performance. Characteristic is that the palaeristeellä Isolation is facilitated when the pattern in a blow insulation is no longer diagonal beams to S 25 - palaeristeellä the underside of isolation has previously been difficult.
    In a preferred embodiment of the invention, there is only raised lower beams extending up to the surface of the non-pressed blow insulation, = which remove cold bridges, improving the energy and moisture performance of the upper floor structure E and facilitate insulation with piece insulation, and making walkways 5 30 - directly on top of the raised lower beam.
