Definitions

  • the invention relates to a method for constructing a formwork unit and a method for producing a concrete element. Finally, the invention relates to a prefabricated formwork device.
  • Wall formwork is used in the manufacture of concrete walls.
  • the wall formwork is made up of two halves of the formwork, the setting formwork and the closing formwork, which are set up and connected to each other at the site where the concrete wall is to be manufactured.
  • the concrete is poured into the space between the setting formwork and the closing formwork to produce the concrete wall.
  • a certain degree of prefabrication can be achieved by forming the setting formwork and the closing formwork from frame formwork, which is transported to the site as prefabricated formwork units.
  • An example of the construction of such a wall formwork is shown in AT10946U1 shown. Nevertheless, many work steps have to be carried out on site under changing working and environmental conditions. This hinders construction progress.
  • the assembly of the wall formwork on site entails safety risks that must be minimized by suitable additional measures. In any case, this requires a high level of deployment of trained personnel.
  • Another disadvantage is the construction noise that the assembly of the formwork entails.
  • WO0238878 Another approach is to use precast concrete elements that are manufactured in a precast plant.
  • WO0238878 For example, it describes concrete walls that are connected by means of reinforcement bars that can be folded together using joints. This allows the transport volume to be minimized.
  • Precast concrete elements are usually transported on trucks. These transports are very complex due to the high weight and dimensions of the precast concrete elements. There is also a risk of damage during transport. In addition, precast concrete elements do not allow for flexible responses to short-term changes in requirements.
  • the object of the present invention is to alleviate or eliminate at least some of the disadvantages of the prior art.
  • the invention has the particular aim of simplifying and standardizing the construction of in-situ concrete formwork at the site of use.
  • the formwork unit is thus assembled in the prefabrication area.
  • the prefabrication area is spatially separated from the place of use, i.e. from the place where the concrete element is manufactured with the formwork unit.
  • the prefabrication area is preferably located next to the place of use on the construction site. In the prefabrication area, the working and environmental conditions can be better controlled than at the place of use. In the prefabrication area, a precise floor surface can be on which the formwork unit is prefabricated. In contrast, the floor area at the site of use, for example the top of a previously concreted ceiling element, can have unevenness or dirt that make setting up the formwork more difficult. Furthermore, particularly high safety standards can be set in the prefabrication area.
  • the formwork unit can therefore be assembled precisely, safely and quickly. Any number of formwork units can also be prefabricated in order to avoid delays at the site of use as far as possible.
  • the prefabrication area can also be equipped with sound insulation which significantly reduces noise emissions from the construction site.
  • the reinforcement can be attached to one formwork element, i.e.
  • the first or second formwork element before the other formwork element, i.e. the second or first formwork element, is provided in order to arrange the reinforcement in the space between the formwork unit.
  • the first or second formwork element is preferably in a standing, in particular vertical, state.

  • the concrete element to be manufactured is reinforced with the reinforcement.
  • the second or first formwork element is preferably also connected to the first or second formwork element in a standing, in particular vertical, state.
  • the formwork unit is installed together with the reinforcement in the space between the first and second Formwork element is transported to the site and set up there.
  • the concrete element in particular a wall element, can then be manufactured by pouring concrete into the gap.
  • the preparation of the concreting process at the site can be made much easier thanks to the prefabricated formwork unit.
  • a formwork connecting element in particular a support element, for example a connecting bar, is preferably connected to the first and second formwork elements, in particular to an upper end of the first and second formwork elements, respectively.
  • the formwork connecting element creates such a rigid connection between the first and second formwork elements that the formwork unit can be transported together with the reinforcement in a predetermined position of the first to the second formwork element, in particular lifted to the place of use using a hoist.
  • the support element in particular made of metal, is preferably provided as the formwork connecting element, which preferably connects the upper ends of the first and second formwork elements to one another.
  • the support element can have at least one profile part.
  • the support element preferably has two profile parts, for example two C-profiles, which are connected to one another. In the connected state, the support element can extend essentially perpendicular to the main planes of the first and second formwork elements.
  • several formwork connecting elements can be provided to connect the first to the second formwork element.
  • the formwork connecting elements are preferably connected to the upper ends of the first and second formwork elements at a distance from one another in the horizontal direction.
  • Two formwork connecting elements can be connected to one another via a railing element, for example a round element, in particular a round tube, thereby realizing an additional function.
  • the location and Directional information such as “top”, “bottom”, “horizontal”, “vertical” refers to a vertical state of use of the formwork unit for concreting a vertical wall element.
  • the formwork unit can also be used in a different position, in which case the location and direction information must be transferred accordingly.
  • the formwork connecting element is mounted on the first formwork element, moved from a rest position to a connecting position, in particular pivoted, and connected to the second formwork element.
  • the formwork connecting element In the rest position, the formwork connecting element is detached from the second formwork element, i.e. the formwork connecting element is connected to the first but not to the second formwork element.
  • the formwork connecting element In the rest position, the formwork connecting element is mounted on the first formwork element, in particular via a bolt connection, while the first formwork element is preferably arranged in the lying state, in particular in the horizontal state, in the prefabrication area.
  • the first formwork element is connected to the second formwork element via the formwork connecting element, preferably in the standing, in particular vertical, state of the first and second formwork elements.

  • the suspension 28 has a height adjustment 31 with which the height position of the suspension bracket 29 in the gap 26 can be adjusted.
  • the height adjustment 31 here has a nut 32 which can be screwed onto the threaded rod to different distances in order to adjust the height of the suspension bracket 29 in the gap 26 accordingly.
  • the lifting device 14 is connected to the formwork unit 3, in particular via a displacement eyelet 33 attached to the formwork connecting element 9.
  • the formwork unit 3 is lifted up from the subsurface of the prefabrication area 1 together with the reinforcement 23 and the recess formwork 24 and, as in Fig. 14 is symbolically shown, lifted to location 2, ie transported hanging freely above the ground.
  • Fig. 15 the formwork unit 3 is brought above the floor surface 2A of the installation site 2 with the lifting device 14.
  • the formwork unit 3 is lowered onto a ground connection reinforcement 34 protruding from the ground in such a way that the ground connection reinforcement 34 is arranged in the intermediate space 26 between the lower regions of the first formwork element 4 and the second formwork element 15.
  • the formwork unit 3 at the installation location 2 is connected to a lifting device 35 for adjusting the height of the formwork unit 3 together with the reinforcement 23 and the recess formwork 24.
  • a lifting element 36 of the lifting device 35 is mounted at the lower end of the second formwork element 15.
  • the lower end of the first formwork element 4 is lowered onto a further lifting element 37 of the lifting device, which is mounted at the installation location 2, here on the front side of the floor.
  • the formwork unit 3 together with the reinforcement 23 and the recess formwork 24 can be adjusted in height, i.e. in the vertical direction, in order to set a desired height of the built-in part, in particular the recess formwork 24, relative to the floor surface 2A of the installation location 2.
  • the height of the marking above the floor surface 2A of the installation location 2 can be measured. If this height deviates from the reference height, here 1 meter, the lifting device 35 is operated to compensate for the deviation.
  • Fig. 18 and Fig. 19 show diagrammatically the formwork unit 3 in the erected state on the floor surface 2A of the installation site 2.
  • the floor surface 2A is designed here as the upper side of a ceiling element of the floor below.
  • Fig. 20 Concrete 39 is poured from above into the gap 26 of the formwork unit 3 in order to produce the concrete element, here a vertical wall element.
  • an inclination of the formwork unit 3 can be set by adjusting the support device 21.
  • the suspension 28 of the reinforcement 23 can be removed and the formwork connecting element 9 can be opened.
  • the formwork connecting element 9 and the railing element 9B form a counter railing, which protects the worker from falling.
  • the formwork connecting element 9 can be blocked against pivoting with a bolt in the open position.
  • Fig. 21 the first formwork element 4 is lifted away from the installation site 2 with the aid of the lifting gear 14 after the concrete 39 has hardened or after the anchor rods have been removed.
  • the second formwork element 15 is lifted away from the installation site 2 using the lifting gear 14.
  • the concrete element has a cutout 40, here a window cutout.
  • Fig. 23 the first formwork element 4 and the second formwork element 15 are cleaned in the prefabrication area 1 before another formwork unit 3 is reassembled for the production of the next concrete element.
  • both the lifting element 36 for the second wall formwork element 15 and the further lifting element 37 for the first wall formwork element 4 are mounted on the formwork unit 3 during prefabrication.
  • the lifting element 36 and the further lifting element 37 are thus lowered together with the first 4 and the second wall formwork element 15 onto the floor surface 2A of the installation site 2.
  • the further lifting element 37 can be arranged at the lower end of the first formwork element 4 and the lifting element 36 at the lower end of the second formwork element 15 during transport from the prefabrication area 1 to the installation site 2
  • This embodiment can be used in the manufacture of interior walls, because here both lifting elements 36 and 37 can be supported on the floor surface 2A.
  • the lifting elements 36, 37 are shown in different positions to illustrate the adjustability.
  • the lifting element 37 on the first formwork element 4 and the lifting element 36 on the second formwork element 15 can be actuated in order to adjust the height of the prefabricated formwork unit 3.
