    The threshold element
    The invention relates to a sill element comprising an elongated sill plate having a lower surface and an upper surface, the lower surface having an elongate insulating piece of substantially the length of the sill plate.
    Garages, garages, warehouses and halls have a large doorway that allows you to enter the building by vehicle. In areas suitable for vehicle traffic, the floor structure is usually a slab made of concrete, and the doors of the premises are generally ascending lifting doors. At the door opening outside the building there is usually a ramp made of concrete or asphalt. There must be a thermal insulation layer between the ramp 10 and the edge of the floor slab to prevent heat from the floor slab to the outside of the building or vice versa. The thermal insulation layer is placed in the building so that it is possibly positioned exactly at the door closing the door opening, whereby the closed door and the thermal insulation layer are positioned substantially on the same vertical line. At the lower edge 15 of the door opening, there is usually mounted a sill plate made of thick sheet metal, the first edge extending outside the door on the top surface of the ramp and the second edge inside the door on the top surface of the floor tile. The function of the sill damper is to protect the thermal insulation layer from mechanical stress and to prevent liquids and substances damaging the thermal insulation from entering the thermal insulation layer.
    There are a number of problems with the structure of door opening thresholds for vehicles. The metal door sill extending from the inside to the outside of the building forms a cold bridge at the door opening, which increases the energy consumption of the building. The sill dampers are usually fixed to the edge of the floor slab bordering the thermal insulation layer by screw fixing. Heavy-duty vehicles drive over the sill trap 25 between the floor slab and the ramp, causing the sill to be subjected to forces that cause it to deform and tend to move the sill. A damaged and loose sill damper cannot adequately protect the thermal insulation against mechanical and chemical stresses. Partially or completely detached sill cover and mounting bolts 30 that may have been detached upon removal of the sill cover can damage the tires of the vehicle driving over it. In addition, a fully or partially detached sill plate creates a risk of injury to people passing through the door opening.
    It is an object of the invention to provide a threshold element which can reduce the problems associated with the prior art. The objects of the invention are achieved by 35 threshold elements, characterized by what is disclosed in the independent patent.
    20176118 prh 14-12-2017 in claim. Certain preferred embodiments of the invention are set forth in the dependent claims.
    The invention relates to a sill element comprising an elongated sill plate having a lower surface and an upper surface. The underside of the sill plate has an elongate insulating piece of substantially the length of the claw plate. The sill plate and the insulating piece are essentially of the same material. The sill element is intended to be installed in the doorway of the building so that the insulating element of the sill element forms at least part of the thermal insulation layer between the edge of the floor slab of the building and the ramp. Preferably, the sill element is installed in connection with the concrete casting of the floor slab of the ra10 building, whereby the insulating piece adheres to the edge of the floor slab as the concrete hardens. Because the sill plate is attached to the insulating part, it always reliably stays in the correct position on the insulating part.
    In a preferred embodiment of the threshold element of the invention, the sill plate and the insulating body 15 are formed as a single unit.
    By a single piece is meant here that the sill plate and the insulating piece are fixedly fixed to each other over the entire area of their interface, so that the strength of the interface plate is equal to the strength of the sill plate and the insulating piece. The sill element can be made directly from a single material into a one piece part, with no separable interface between the sill plate and the insulating body.
    In another preferred embodiment of the sill element according to the invention, the insulating body has a first side surface and a second side surface, the side surfaces having an upper edge extending to the lower surface of the sill plate. The sill plate has a first edge and a second edge such that the distance between the first edges of the first side surface and the second edge of the second surface is less than the distance between the first edge and the second edge of the sill plate. The width of the sill plate is thus larger than the width of the upper edge of the insulating piece. Thus, the edge portions of the sill plate mounted in the door opening cover the seam between the insulating piece and the floor slab inside the building, as well as the outside seam between the insulating piece and the ramp. This prevents water or other liquids from leaking into the seams, which could cause damage to the sill element or floor structures.
    In a third preferred embodiment of the threshold element of the invention, the first side surface and the second side surface of the insulating body have a lower edge and the distance between the upper edges of the side surfaces is less than
    20176118 prh 14-12-2017 Distance between lower edges. The insulating piece is thus wider at its lower edge than at its upper edge. The shape of the insulating body prevents the sill element from rising upward when it is inside a gap of the same shape as the insulating body. Such is the case, for example, when the sill element is molded between a concrete lat5 slab and a concrete slat during the floor and slat manufacturing step.
    In a further preferred embodiment of the threshold element according to the invention, the first side surface and / or the second side surface have gripping members. Preferably, the engaging means comprise projections and / or recesses on the side surface. The engaging means may comprise elongated grooves or bellows on the side surface extending along the length of the sill element 10 or formed by shaping the side surface of the insulating body. The gripping elements allow the insulating piece to adhere better to the building components on the side of the insulating piece.
    In yet another preferred embodiment of the threshold element according to the invention, the insulating body has at least one longitudinal cavity of the threshold element. The On15 roll may be of circular or polygonal cross-section. By forming a cavity, the material of the sill element can be saved.
    In yet another preferred embodiment of the threshold element according to the invention, the insulating body has at least one hole extending from the first side surface to the second side surface. The hole thus passes through the insulating body in the transverse direction with respect to the length element 20 of the threshold element. Holes can be installed in the holes that bind the concrete parts of the insulating part together.
    In another preferred embodiment of the sill element according to the invention, the sill plate and the insulating body are made of polyurethane elastomer, polyurea, rubber or a mixture thereof. The material for the sill element may also comprise a recycled mixture of the above materials.
    An advantage of the invention is that it speeds up the production of door openings for vehicles in buildings and improves their operation.
    A further advantage of the invention is that it improves the thermal insulation performance of door openings for vehicles.
    A further advantage of the invention is that it reduces the need to maintain door openings for vehicles.
    20176118 prh 14-12-2017
    A further advantage of the invention is that it reduces the risk of damage to vehicle tires.
    The invention will now be described in detail. Reference is made to the accompanying drawings, in which Figure 1 illustrates an exemplary sill element according to the invention in a front elevation view and Figure 2 exemplifies a door opening threshold having a threshold element according to the invention.
    Fig. 1 shows, by way of example, a threshold element according to the invention, as seen from the front notch. The sill element is an elongate body having an insulating body 16 of substantially rectangular cross-section, having a first side surface 18, a second side surface 20 and a lower surface 19. Each side surface has gripping members 22 in the form of in the direction of the underside of the insulation. With the exception of the gripping members, the side surfaces are substantially flat surfaces. The side surfaces have an upper edge 28 and a lower edge 30 such that the distance between the upper edges is less than the distance between the lower edges, i.e. the width of the insulating piece decreases as it moves up from the lower surface. In this specification, the width of the insulating body 20 is defined as the distance between the first side surface and the second side surface of the insulating body.
    Preferably, the width of the lower edge of the insulating body is about 100 mm and the distance of the upper edge is about 90 mm.
    Inside the insulating piece there are two longitudinal cavities 32 of the insulating piece. In Figure 1, the cavities have a circular cross-sectional shape, but may also have 25 other cross-sectional shapes, such as a rectangle. For example, the cavities may have a diameter of 45 mm. The insulating body further comprises a plurality of holes 34 which pass through the insulating body transverse to its longitudinal direction, i.e., the holes extend from the first side surface 18 of the insulating body 16 to the second side surface 20 of the insulating body. Preferably, the holes have a diameter of 12 mm and are spaced every 500 mm along substantially the entire length of the sill element.
    Above the insulating piece is a sill plate 10 with an upper surface 14, a lower surface 12, a first edge 24 and a second edge 26. The distance between the first edge and the second edge is greater than the first side surface 18 of the insulating body.
    20176118 prh 14-12-2017 The distance between the top edge 28 and the top edge 28 of the second side surface 20, i.e., the width of the sill plate is greater than the width of the top of the insulating body. Thus, a strip on both sides of the insulating piece remains visible on the underside of the sill plate 12. The width of the lower strip on the various sides of the insulating piece may be 20-50 mm. The upper surface of the insulating body 5 is an upwardly convex curved surface.
    The sill element may be of polyurethane elastomer material, polyurea, rubber or a mixture thereof. The material may be entirely new material or it may contain recycled material, whereby the material is a mixture of new material and recycled material. Preferably, the proportion of recycled material is up to 50%. Preferably, the material has a density of between 0.7 and 1.5 kg / dm 3 The material may further comprise reinforcing fibers or other additives. The material of the sill element has a thermal conductivity of 0.12-0.25 W / Km, whereby the insulating body acts as a clearly insulated thermal insulator. The material can be foamed during the manufacturing process, resulting in small air pockets which reduce the thermal conductivity of the material within the material. The sill element can be made by dropping it into a profile or by molding it.
    From a manufacturing point of view, the sill element is most economical to manufacture directly by dropping into a single piece. However, it is possible to first make the sill plate and the insulating part separate and join them in the subsequent 20 manufacturing steps. The insulating piece and the sill plate can be permanently joined to each other, for example by gluing, or they can be attached to each other for release, e.g. The sill element can be made into a piece of suitable length, dimensioned for a given door width, during the manufacture of the element. Although the sill element is particularly well suited to door sill structures specifically designed for vehicles 25, it can also be used in door openings for other traffic such as persons, particularly when a lifting door is installed in the door opening. The length of the sill element can thus vary from about one meter to several meters depending on the width of the door opening.
    Fig. 2 shows, by way of example, a cross-section of a door opening at the bottom, which has a threshold element according to the invention. The sill element is easiest to install during the construction phase of the building when casting the concrete floor tile 100 of the building. The sill element is mounted and supported at the doorway of the building adjacent to the plinth 104 so that the threshold element is aligned with the vertical line with the door 108, preferably 35, which opens into the doorway. The sill element is supported in height so that the lower surface of the sill plate 10 is flush with the upper surface of the floor tile 100
    20176118 with prh 14-12-2017. The holes in the insulating piece are provided with gripping steels 110 extending through the insulating piece from its first side to the second side of the insulating piece. A reinforcement mesh is installed over the insulating layer 106 below the floor tile and the necessary HVAC installation is made. After this, 5 concrete slabs are poured. At the same time, a ramp 102. may be cast outside the door opening. After the concrete has hardened, the sill element will adhere to a groove of the same size formed between the ramp and the floor slab. The upwardly tapering shape of the insulating piece and the gripping means on the side surfaces of the insulating piece prevent the insulating piece from rising upward in the groove, thereby ensuring that the sill element is held in place.
    The sill element is subjected to mechanical stress during the installation phase and especially after the building is commissioned, which sets requirements for the material of the sill element. Preferably, the material has a tensile strength of 10-70 MPa and a long-term compression strength of 10 MPa. Preferably, the material has a wear resistance of 20-60 mm 3 (DIN53516) so that the sill element has a sufficient service life in normal use. The choice of base material for the sill element achieves sufficient weather resistance and resistance to chemical agents used in vehicles.
    The sill element is particularly suitable for new buildings to be installed, but it can also be retrofitted to existing buildings.
    It is good to consider the possibility of retrofitting the sill element when designing the insulation element and the gripping elements of the sill element.
    Some of the preferred embodiments of the threshold element according to the invention have been described above. The invention is not limited to the solutions described above, but the inventive idea can be applied in various ways within the scope of the claims.
