Definitions

  • the invention relates to a method for producing a prefabricated component for a building, a prefabricated component, a frame for installation of a window frame in a wall element, and a method for fastening a window frame to a frame connected to a wall element.
  • the said equipment includes fasteners for connection to other components, external insulation and facade elements and in particular also windows and door elements.
  • fasteners for connection to other components, external insulation and facade elements and in particular also windows and door elements.
  • the precast concrete element is provided with equipment elements and serving as the outer wall of a building wall element in which at least one window is installed.
  • a formwork frame is first prepared.
  • the formwork frame has a flat bottom whose surface defines the later building inside of the wall element.
  • the at least one window element to be installed is installed in the formwork frame at a predetermined position, optionally with spacers arranged on the formwork floor.
  • flowable concrete also referred to as fluid concrete or liquid concrete
  • the at least one window element at least partially surrounded by concrete and thus sealingly connected to the precast concrete component.
  • a reinforcement preferably made of steel and shed with.
  • From the DE 10 2013 013 074 A1 is a construction consisting of a frame and a window frame known.
  • the frame is already firmly and sealingly connected to the window frame for the production of prefabricated part, including a screw with circumferentially arranged screws is used.
  • a part of the frame is surrounded by concrete during the production of the precast concrete component, so that a watertight structural transition is created between the frame and the prefabricated concrete component. Since a more tight connection between the frame and the window frame is made via a correspondingly formed seal, no post-processing of the built-in window in the precast concrete component is required.
  • the industrial production of the precast concrete component with at least one window a high reproducibility in the production of precast concrete components of buildings is achieved. This reproducibility is also associated with a higher speed and improved quality compared to a conventional construction of buildings. Because the manufacturer of precast concrete components is able to define and control the manufacturing process in their own production. This possibility exists in a construction of buildings whose parts are produced only on site, only to a limited extent.
  • precast concrete components Since the supply of precast concrete components usually does not represent a bottleneck in the production of precast concrete components, it is necessary that the additional equipment to be installed is of the correct quality and number at the production site. This can lead to bottlenecks, especially in the case of windows, since in the planning of office buildings the definition of a special type of window often takes place very late. This then leads to required short manufacturing and delivery times for the window manufacturer. However, if there is a bottleneck in windows or window frames, which must be present in the production of a wall element according to the prior art, this inevitably leads to delays in the production of precast concrete components.
  • the present invention is based on the technical problem of simplifying the production of precast concrete components with at least one window.
  • a method for producing a prefabricated building in which the prefabricated component is produced in two separate steps, in which in a first step a wall element together with at least one opening forming a frame of flowable wall material is poured and cured and in which in a second step, a window frame is sealingly connected to the frame.
  • the prefabricated components may not only consist of concrete, but also of a different material.
  • materials for example plastics, natural-plastic materials, high-strength concrete or fiber-reinforced concrete come into question.
  • the materials mentioned before flowable and then harden so that in particular the frame is firmly connected to the cured material.
  • the invention will be described below for a better understanding overall on the basis of the use of concrete, but this is not to be understood as limiting.
  • the curing of the wall material or the concrete can be done by simply timing through the running in the wall material processes. In addition, a tempering and / or special ventilation of the not yet cured wall material can take place.
  • a window frame made of a metal can have plastic parts for the thermal separation of outer and inner parts of the window frame.
  • the window frame can also consist of a natural material, such as wood. Ultimately, it depends on the dimensional stability of the frame and the window frame to ensure a permanently tight building transition on the one hand between the wall element and the frame and on the other hand between the frame and the window frame to be installed.
  • the frame is partially surrounded with concrete, which results from the hardening of the concrete between the prefabricated part and the frame a dense building transition. This building transition requires no post-processing on the construction site.
  • the window frame is then sealingly connected to the cast-in frame in the second work step, preferably also in this case a dense building transition occurs.
  • the production of the finished component is already simplified because a frame without associated window frame a has significantly lower weight and thus can be handled easier to position them in the formwork frame.
  • This increases the speed of preparation of the formwork frame.
  • the lower weight of the frame facilitates the accuracy of installation and positioning in the formwork frame, so that thereby a greater quality in the production of the finished component is achieved.
  • any bottleneck that may occur in the delivery of window frames does not affect the production of prefabricated components. Since the frame is either always the same regardless of the design of the window frame or there are only a small number of variants of the frame, an always sufficient supply of profile parts can be easier than it is the case for individual window frames. Thus, the production of prefabricated components can be carried out independently of the delivery of window frames.
  • window frame is already inserted with built-glass or other transparent material in the prefabricated part and the frame.
  • the window frames are already supplied by the manufacturer with the window pane inserted, or the window panes are already connected in advance to the frame regardless of the production of the prefabricated component and then inserted together into the prefabricated component.
  • the set-up time for attaching a complete window to the prefabricated component can be reduced and the entire production process can be accelerated.

  • the mounting portion of the window frame is fixed in the second step. Since a layer of insulating material is usually applied to the outside of the component, the mounting portion at least partially covers this insulating layer. This arrangement promotes the integral formation of the prefabricated component in the form of a wall element with window.
  • a flange portion of the mounting portion protrudes inward in the direction of the opening of the window and a directed towards the inside of the wall member towards sealing surface and that in the second step, the window frame coming from the inside of the wall element with the flange portion is sealingly connected.
  • the installation of the inside of the wall element has both the factory and on-site the advantage of easier accessibility during installation.
  • a wall element in the form of a prefabricated part are most equipment elements, such as insulation and facade elements on the outside, while the inside usually has less equipment elements. If the window frames are only installed on the construction site, the installation of the window frames from the inside has the further advantage that the insides of the wall elements are more easily accessible and that the construction of a scaffold or the use of pallet trucks can be avoided.

  • the displacement is about 2 to 5 mm.
  • the length of the clamping pieces is for example about 50 mm with a width of about 15 mm and a height of about 12 mm. Depending on the size of the window to be installed or the one used Materials of the frame 8 and / or the window frame 20 may vary these dimensions.
  • a plurality of pairs of clamping pieces 58 and 60 along the circumference of the frame 8 and the composite of individual frames 8 frame are arranged distributed to produce a total uniform contact pressure between the window frame 20 and frame 8.
  • the distance between the pairs of clamping pieces 58 and 60 is in the range of 20 cm to 100 cm, in particular in the range of 60 cm.
  • Fig. 14 shows in cross-section the compressed installation situation (arrow B) Fig. 13 ,
  • the two clamping pieces 58 and 60 are firmly clamped between the side surface 74 of the window frame 20 and the longitudinal edge 56 of the mounting groove 52, wherein still a gap 76 between the longitudinal edge 54 of the mounting groove 52 and the guide member 62 of the clamping piece 58 is present.
  • top clamps 58 and 60 can be marked to simplify selection of clamps for a user to form mating pairs (right / left or different sizes).
  • a window frame 20 in a prefabricated part 2 for a building with a frame 8 and with a window frame 20.
  • the frame 8 is a closed frame and are with the inside 78 of the connecting portion 28 and the inside 80 of the mounting portion 30 before an inner cross section.
  • the flange portion 32 bounds the inner cross section of the opening 6 in the direction of the outer side 26 of the wall element 4.
  • the outer dimensions of the window frame 20 further form an outer cross section which is smaller than the inner cross section of the frame 8.
  • the window frame 20 has a sealing surface 36, which in the installed state with the sealing surface 34 of the frame 8 and cooperates with a sealing element 38 for establishing a tight connection.
  • Fig. 8 shows the installation situation on the parapet, in which the window frame 20 rests with its projecting end face 82 on the inside 80 of the mounting portion 30.
  • Fig. 9 shows the installation situation on the lintel, wherein the end face 82 has a distance from the inside 80. In the vertical direction, the outer cross section of the window frame 20 is thus smaller than the inner cross section of the frame 8.
  • the sealing element 38 is shown. In the 15 to 17 Now, the sealing element 38 is explained in detail.
  • the configuration and in particular the installation situation of the sealing element 38 at the corner of the frame 8 basically represents an independent of the above-described embodiments of the invention solution of the above technical problem and thus an independent invention.
  • Fig. 15 shows the sealing element 38 both in cross-section and in a three-dimensional shape.
  • the seal 38 has a fastening portion 90, a substantially quarter-circle-shaped sealing portion 92 in cross section, and a support portion 94 adjoining the sealing portion 92.
  • the material used for the sealing element 38 is an elastic material, in particular a material based on rubber or a permanently elastic plastic.
  • the attachment portion 90 is formed in cross section in the form of a push button to engage in the in Fig. 10 shown in detail receiving groove 50 having undercut side edges to be pressed one.
  • the sealing element 38 can be connected to prepare the installation of a window frame 20 with the frame 8 circumferentially.
  • the attachment portion 90 has a cavity 96.
  • the sealing portion 92 also has a cavity 98, so that the shape of the sealing portion 92 is deformable during installation of the window frame 20 and thus possibly compensate for unevenness and minor edges and can respond to the smaller distance between the sealing surfaces. Nevertheless, the sealing portion 92 generates due to its elasticity sufficient resistance to ensure when connecting the window frame 20 with the frame 8 a complete seal.
  • the support portion 98 has a flat contact surface 100 and a plurality of ribs 102.
  • the contact surface 100 serves to bear against the sealing surface 34 of the flange portion 32, while the ribs 102 come into contact with the sealing surface 36 during installation of the window frame 20.
  • Fig. 16 shows the installation situation of the sealing element 38 in a rectangular corner of the frame of the frame 8.
  • the support portion 94 is divided by a cut, so that two cut edges 104 and 106 result.
  • the section of the sealing portion 92 and the mounting portion 90 are not damaged by the cut.
  • the adjustment of the sealing element 38 to a predetermined size of the window frame 20 can be done easily and quickly.
  • the sealing portion 92 bulges at the location of the angle in the direction away from the support portion 32. This bulging leads to the advantageous effect that in particular in the corner of the frame 8 increased sealing material is present. Since the sealing of such a corner is fundamentally problematic, this increased sealing material leads to an improved seal between the frame 8 and the window frame 20th
  • Fig. 17 now shows another measure to improve the sealing in the corner.
  • a strand 108 along the running around the corner edge around sealing portion 92 is applied, which provides additional sealing material for the critical region of the corner.
  • the strand 108 extends approximately 5-10 mm to either side of the corner.
  • the material used for the strand 108 is an elastic material or an elastic plastic, preferably a polymer, in particular an MS polymer.
