Definitions
- the present invention relates to the above-mentioned stress and thus relates to the creation of flat precast concrete parts on site.
- An alternative and often preferred method of construction consists in first producing supports, trusses and roofs and then under their protection a quality-appropriate sole. This procedure is often significantly faster in the appointment, because the production time of the sole is not on the so-called critical path of the overall completion of the building.
- the object of this invention is to provide something new for commercial use.
- a first essential aspect of the invention thus provides that at an early point in time, that is to say before a large-scale application or creation of the sole, a sub-base is provided for at least one form of formwork that can be used in series production, and the flat precast concrete parts produced therein are produced on-site in a pile, the Precast concrete parts are preferably transversely transported to the heap and / or later to the installation site using a small-lever crane; a crawler crane and / or alternatively a mobile crane and / or a mobile crane with panel truck and / or truck operation can preferably be used as the crane; Small lever arm means preferably with a radius below 25 m, particularly preferably below 15 m lifting radius.
- the serial production site stockpile distance will typically be less than 300 m, maximum 500 m if crawler cranes are used.
- precast concrete elements such. B. flat walls, perforated facades or Pi, W ⁇ *, ceilings come into consideration.
- a first variant of the method and of the equipment provides, as is possible in principle, to use a solid base instead of a base layer which is preferred in production, e.g. B. preferably to create a removable, transportable steel structure (z. B. girder grate) and preferably to use multiple times.
- the multiple use can in particular by stacking. Dividing (stack casting) or by always new excavation from a Sereinform, as known in principle from series production.
- the formwork floor does not have to be changed between individual concreting cycles. H. that it only has to be designed once, e.g. B. 10 to 100 to perform concreting cycles; Furthermore, a reusable edge formwork is used and this is preferably inclined with Stur_z. inclined and firmly connected to the ground in order to avoid opening. This enables both a tilt-up procedure and, as required, vertical lifting.
- a crawler crane either moves in front of the head or next to the plate (see FIG. 1) and attacks there with at least one rope strand on a crossmember, preferably as presented in more detail below.
- a second strand engages, provided that the traverse is not placed on the ground at one end (possibly also in a holder) and is moved in with the crane in the direction of erection.
- the crane superstructure when erecting when moving the crane from the top of the plate to the base; however, the sole or formwork may need to be suitably protected against caterpillar tracks. If, as preferred, the crane is next to the long side of the along the ballast bed, a rotary movement of the superstructure is preferably provided before the transverse transport of the plate can begin. Furthermore, and / or in addition, it is generally also necessary to provide for the then vertical plate to be rotated about its vertical axis.
- a further variant is particularly preferred (see FIG. 3), in which the crawler crane stands in front of the head of the concrete slab, in particular on a suitable surface, such as the ballast of a later sole, and in which Erecting and rotating the plate is operated more than one strand.
- an auxiliary crane is located on the opposite side of the crawler crane, which can preferably be an available mobile crane, which pulls the second strand during lifting and, depending on the stop mechanism, lifts a certain plate load, usually half the plate load.
- the crawler crane operates in two-winch operation. Both winches pull to lift. One winch releases to turn while the other pulls up.
- Another particularly preferred is the use of a second tip, which ensures that there is a distance between the two lifting cables in the plan. This also limits unintentional turning (wind, etc.) around the vertical axis, since both twisted ropes generate a restoring torque. The same applies to the pendulum movements of the plate.
- partition walls particularly preferably fire protection walls which are installed between or actually in front of supports which have been installed in advance and span from support to support. So far, these panels were typically threaded into the grooves between the supports at a height of only 2 to 3 meters or otherwise suitably installed, with a suitable number of longitudinal joints.
- hangers on the intermediate and head and foot pieces in particular exclusively or at least essentially exclusively for the transmission of tensile forces perpendicular to the plate plane. Tensile forces occur when the panel is lifted and, in the case of thin and tall panels, immediately after they have been set down during final assembly as a result of kinking the panel. These hangers are particularly preferably arranged in at least two rows along the longitudinal axis of the cross member in order to prevent the plate from tilting relative to the cross member.
- a head piece (see FIG. 5) particularly preferably at the (in the end position) upper plate end with at least one support for receiving its own weight in the vertical state, with which all forces act in the plane of the plate.
- Two spurs are preferably provided which, in a statically determined manner, enable the vertical forces to be diverted into the crossmember.
- Such supports are also possible at the base, but this means that the dead weight must be guided lengthways through the entire traverse.
- At least one attachment means preferably acts on the head piece, which, when lifting, has half its own weight and, when hanging, a maximum of the entire egg has to lift counterweight. This robust arrangement means that the greatest loads are concentrated at one point and not carried out by assembly joints etc.
- statically undetermined storage conditions represent a security risk, which is also one of the main reasons for the limited applicability of the American tilt-up method with its simple, few hanging points.
- Handling is made much easier according to the invention, even for large slabs, in that six to approximately ten or fourteen anchor points are securely arranged in large slabs in order to ensure uniform support of the slab in the state of construction and to enable low reinforcement contents and thin thicknesses associated therewith.
- Statically indefinite storage can be permitted, but a combination of one or more of the following measures can be taken to ensure that the negative effects remain limited or that forces are safely derived.
- the counter plate on the opposite side is chosen so large that the maximum possible load from statically indefinite storage can be absorbed.
- This can be done, for example, with sufficiently large counter plates or line bearings (supports), which can preferably be used again after assembly. Although this may initially seem uneconomical and paradoxical, local overload can be tolerated. It is only important to ensure that the distance between the anchors is sufficiently large in relation to the plate thickness (which causes the constraining forces due to their rigidity). This is preferably chosen to be so large that a forced deformation does not exceed the additional safety margin.
- the series-produced components in particular rod-shaped or filigree series components, can be used in conjunction with perforated facades as a preferred application.
- perforated facades are preferably produced on construction sites, preferably with their element sizes that are no longer easily transportable by road. Ceiling heights of offices, shopping centers, hotels etc. are often so high (typically over 3 m and especially up to 4 - 5 m) that they no longer exceed. the road can be transported, or only inclined, and in expensive and limited available special low-loaders. Tilt-up is therefore also suitable as the production method, but the inventor's sole formwork method is preferred.
- Typical series applications are over 10, in particular over 20 applications per construction site and more preferably in the use of at least essential parts of the formwork sets for several construction sites (steel parts, the molded ends for ceiling supports or edge beams, support templates and formwork aids such as Hydraulics and their stamps and borders used several times on different construction sites).
- Formwork sets and / or edges can be a fall, especially for. B. have a camber angle of 1:20 and / or be provided with in particular reusable wood, steel and / or plastic inserts and / or floors and / or edges for better loosening.
- the 1:10 to 1:40, preferably 1:20 inclination enables many cycles in one formwork without dismantling or edge formwork when stripping.
- Such a preferred element is essentially ceiling-high and, depending on the weight and available lifting equipment, is preferably exciting over a grid, preferably with an integrated edge beam.
- ceiling or column anchoring reinforcement to be arranged can be represented by various known built-in parts (screw connections, rebend connections, loops etc.).
- a perforated facade element according to the invention is described only by way of example in FIG. 8.
- the preferred sizes of such plates are preferably between approx. 15 m 2 (limitation due to the ease of transportability of the parts conventionally produced in the factory) and 50 m 2 (weight limitation due to commonly available hoists), particularly preferably between 20 and 40 m 2 .
- Variants of the American tilt-up method can be considered as the preferred assembly method, particularly preferably in connection with a sole edge formwork that can be easily dismantled in the foot area (e.g. a steel edge formwork, which is preferably held with a few bolts or only by magnets), which simplifies this Pulling out and rotating around a support line on the floor is not impeded.
- a sole edge formwork that can be easily dismantled in the foot area (e.g. a steel edge formwork, which is preferably held with a few bolts or only by magnets), which simplifies this Pulling out and rotating around a support line on the floor is not impeded.
- the further assembly routine can be done as per. se known, ie for example in particular by lifting and placing on the lower ceiling, preferably in mandrel / cup centering and stiffening by auxiliary support on the lower ceiling.
- lifting and placing on the lower ceiling preferably in mandrel / cup centering and stiffening by auxiliary support on the lower ceiling.
