Definitions

  • the present invention relates to what is claimed in the preamble and is therefore concerned with the production of precast concrete parts.
  • the object of this invention is to provide something new for commercial use.
  • the present invention thus proposes, in a first basic idea, a battery formwork arrangement for building construction which is immobile at the site and not moved during several work cycles, with variable formwork chambers for the successive production of differently reinforced precast concrete elements having floor and side walls, in which it is provided that at least one formwork chamber side is formed as a formwork wall separated from a formwork chamber floor and movable against it in use.
  • a first essential aspect therefore consists in the knowledge that considerable advantages are obtained close to the construction site if the formwork chamber wall is designed to be movable against the formwork chamber floor.
  • the movement is realized in the form of a displaceability for the purpose of defining the formwork chamber, this facilitates the manufacture of different precast concrete parts with essentially identical elements on the construction site, without having to keep a large number of different inserts etc. available. It is possible, for example, to use only a small number of base plate elements of different shape and / or size. When moving the side parts and, if necessary, a few other additional elements, a large number of different precast concrete parts can be realized. This initially allows precast concrete parts to be economically produced with a battery formwork arrangement even if only small series of five to ten pieces are required, in particular when producing at least, for example, twenty parts of the same width.
  • actuators that promote the loosening of the precast concrete element from the ground, although such actuators can be easily provided; Particularly noteworthy are hydraulically acting actuators, which push the component to be lifted or lifted upwards away from the formwork floor.
  • hydraulically acting actuators which push the component to be lifted or lifted upwards away from the formwork floor.
  • a large number of actuators can be distributed over the length of a component, that the forces introduced into the component can be distributed via load distribution plates, and that controls for the actuators can be provided that result in uniform component loading
  • Embodiments are not absolutely necessary and appear primarily necessary for very large formwork forms or precast concrete parts due to the increased structural outlay for the battery formwork arrangement.
  • the adhesive forces to the floor that still have to be overcome without lifting the actuator are typically so low that the hardened precast concrete element can be lifted upwards. This allows the battery circuit assembly to be discharged without rotating it. On the one hand, this has the advantage that the area required for the battery circuit arrangement on the construction site can be smaller; on the other hand, the precast concrete element can be picked up immediately from a defined position and, if necessary, installed without settling; intermediate storage is obviously also possible.
  • the battery circuit arrangement will preferably be able to be arranged and / or extended.
  • the sequence of battery tion modules is possible, for example, by screwing or bolting.
  • the sequence means that longer components can be manufactured or a battery formwork length can be better used. For example, if a component would only use 60 percent of the length of a battery formwork arrangement, three precast concrete parts can be produced simultaneously by lining up two identical battery formworks and manufacturing the middle component in the joint area, and the length of the unused battery formwork area is no longer 40 percent, but only 10 Percent.
  • a single battery circuit arrangement can have a length that can still be transported without problems on a truck or the like, ie for example under 15 to 18 m, without significant transport difficulties, be it that a battery circuit arrangement or elements required for this are transported with lengths, which as a whole are still free of transport permits, be it that, if only in exceptional cases, battery formwork arrangements are transported in lengths that are still transportable or require lower approval levels.
  • the battery circuit arrangement can typically be dismantled and assembled on site, with both the individual parts and the total weight being low in comparison with the masses to be produced.
  • the battery formwork arrangement is provided for installation on flat terrain that may be attached.
  • a standard floor assembly is typically used, on which in particular the longitudinal coupling can be done by screwing, bolting or the like.
  • the base frame can preferably be leveled in order to prevent uneven precast concrete parts, which may possibly be unusable, from being produced on a, if necessary, only slight slope.
  • the formwork chamber wall is typically folded down both for formwork removal and for equipment before the concrete is filled. While only a small folding section is required for the formwork removal, which is sufficient to separate the prefabricated concrete part from the formwork form, it is preferred if the foldable formwork chamber side can form at least an obtuse angle to the formwork floor. For the insertion of smaller reinforcement cages, such as those weighing less than 500 kg - 1,000 kg, it is not absolutely necessary for the formwork chamber side to be fully opened. Nevertheless, it is preferred if the formwork chamber side can be folded down so far that reinforcement cages and other elements can be inserted laterally. This facilitates the alignment of the reinforcement in the form and enables much more pleasant, easier work for the energy-consuming work on the construction site.
  • the formwork chamber wall can be fastened in or on this base frame.
  • a folding foot can be provided on a formwork chamber side wall element which is connected to the floor assembly, i.e. screwed to the base or connected in some other way. It should be mentioned here that in exceptional cases, such as when a very large number of precast concrete parts of the same type are to be manufactured, such a foot could possibly be welded onto the sub-element or otherwise permanently and permanently connected to it.
  • the formwork wall will typically have a height that is sufficient to form prefabricated concrete parts with a height of preferably more than 70-100 cm in order to obtain a particularly high saving per m 3 of concrete in the formwork.
  • Such great heights are otherwise difficult to produce with little effort, particularly due to the adhesive forces. Accordingly, great heights are preferred due to the inexpensive formwork method.
  • the definition of the component height can be carried out in a simple manner by providing triangular strips or the like at the corresponding height and subtracting them at this height when filling the formwork chamber.
  • the provision of such triangular strips is therefore preferred. Length adjustments are just as easy by moving the end walls.
  • the battery formwork arrangement is typically used with flaccid reinforcement, it being particularly preferred that there is only flaccid reinforcement, so there is no need to prestress the mold. It was mentioned above that the sagging reinforcement in the form of reinforcement cages, dynamic mats and the like can be inserted easily and how this insertion can be carried out with the aid of a machine.
  • the side wall surfaces can be formed by plastic or steel, which is preferred over the use of formwork panels or wooden elements.
  • the reason for this lies in the greater durability, whereby possibly higher basic investment costs for the preferred materials mentioned amortize easily due to the long usability and the replaceability for different precast concrete parts.
  • In contrast to wooden formwork significantly more than 30 switching cycles are possible, typically even up to 100 cycles.
  • Sealing strips in particular triangular strips, can be provided in the area between the base and side wall elements.
  • the base and side wall elements are typically stiffened or reinforced outside the formwork panels made of plastic, steel, wood or the like, for which purpose a steel rib construction or the like, in particular, is provided on the side can be and on the floor side the floor assembly ie the underframe contributes.
  • the base plate itself can exceptionally preferably be formed with formwork panels made of wood due to the given cut due to width adjustments, but is preferably also made in particular of black steel or plastic.
  • Steel for the floor assembly can be galvanized, regardless of the typical chemical reactions between concrete and zinc, as the floor assembly is exposed to particularly abrasive loads and the floor assembly is protected against concrete contact by the formwork panels.
  • the side walls can be held together by at least one anchor, which holds them together during the filling and hardening of the concrete.
  • a suspension can be provided in the armature, which results in a pretension in order to facilitate the separation later, and the armature can in particular be realized with a threaded spindle, which drives the side walls apart when actuated and thus facilitates stripping.
  • a plurality of threaded spindles or other actuators and / or tie rods or the like are advantageously present.
  • plates are fixed to the end faces of the battery formwork arrangement, which can also be sealed against the sides or the bottom with nail strips, triangular strips or other sealing strips and which are fixed in particular by means of magnets.
  • the formation of the side wall or the substructure or reinforcement structure behind the actual surface made of steel is advantageous because the fixing magnetic elements can be placed on it. Protection is also claimed for the use of a battery formwork arrangement as described for the production of a precast concrete part that is free of camber on the side wall.
  • a preferred manufacturing method of the invention will at most require a double striking in the case of precast concrete parts between manufacture and installation.
  • the place of manufacture and the place of installation or possibly also the location of an intermediate storage will preferably be in the swivel range and / or travel range of construction site cranes. This greatly simplifies handling logistics.
  • Figure 1 is a cross-sectional view through a battery formwork arrangement according to the invention shortly before stripping.
  • a battery formwork arrangement 1 for variable formwork chambers 2 for the successive production of differently reinforced precast concrete parts 3, having bottom and side walls 2a, 2b, at least one, in the present case preferably both formwork chamber Sides 2ba, 2bi are formed as a shuttering wall separated from the shuttering chamber floor 2a and movable against it in use.
  • the battery formwork arrangement 1 serves as a battery folding formwork 1 for parts of 10 to 100 t precast concrete weight with variable geometry.
  • the battery circuit arrangement has a base frame la, which can be placed on a fixed base 4 and can be leveled thereon.
  • This base frame is stiff enough to ensure stability during the work cycle, but for reasons of expenditure, it is preferably not designed to bridge cavities over long distances. Therefore, it is designed for use with a paved surface.
  • grid holes lal are provided, in which fastening elements for floor elements 2a and foot elements' of the movable side elements 2ba, 2bi can be used.
  • the battery formwork arrangement is, as is preferably possible, designed for the side-by-side production of two different elongated, reinforced concrete prefabricated parts and has a central group 1b for this purpose, which is also displaceable on the base frame 1a and by screwing screws which pass through the grid holes 10a is.
  • spindle passage openings Ibl are provided, through which threaded spindles 5 pass, which serve to fix the side formwork walls during the filling of the formwork chambers 2, for which purpose they can absorb the tensile forces acting when pouring liquid concrete, that is, sufficiently tensile strength are formed, and which ter after hardening of the precast concrete in the formwork chamber 2 are suitable to be able to fold down the outside wall 2ba by overcoming the adhesive forces between the precast concrete and the formwork wall by relaxing spindle actuation.
  • FIG. 1 shows a threaded spindle 5 only on the right-hand side, which secures or relaxes a formwork chamber for a rectangular beam there, evidently such pressure-resistant relaxation and / or Tie rod means can be provided.
  • the formwork chambers 2 are dimensioned for precast concrete parts that have a height of e.g. Can have 1.60 m, it being obvious that the invention can also be used with smaller components or, provided the individual elements have appropriate stability, also with larger components.
  • the formwork chamber wall 2ba on the outside has a foot 2ba 1, which is screwed to the base frame la by screws which pass through the locking holes 10a.
  • the choice of different grid holes allows the determination of the base area of the precast concrete to be manufactured. Since the grid holes can be manufactured with high precision, the geometry is defined very precisely and with high precision.
  • the foot 2bal of the formwork chamber wall is provided with an axle hole 2ba2, through which an axis 2ba3 passes, which is firmly connected to a support structure made of steel beams 2ba4 for the formwork skin of the actual formwork chamber wall 2ba5 (see FIG. 3).
  • the support structure 2ba4 is around this shaft 2ba3 completely foldable down to the floor, provided that it is not stabilized by the threaded spindle 5.
  • the support structure 2ba4, like the side wall 2ba5, is formed from thick steel sheet, in particular black sheet, and is therefore highly wear-resistant, ie far more than 30 parts can be manufactured without replacement. In particular, such a wall is chosen that more than 100 precast concrete parts can be manufactured without wear or destruction.
  • a formlining made of plastic is arranged on the steel beams.
  • This formwork shell thus forms the actual formwork plate in contact with concrete.
  • the formlining is preferably made of plastic and can preferably be an Alcus panel from the company Fafa; this plate is nailable and easy to touch up.
  • a sealing triangular strip 6 is provided, which prevents concrete from escaping through the intermediate gap.
  • End plates are provided on the end face, which are fixed by means of magnets which adhere to the steel supporting structure of the formwork chamber sides 2ba. These end chamber sides are also to be sealed with nailable sealing strips on the formwork chamber side.
  • the formwork chamber wall 2bi is formed per se in the same way as on the outside, except that in the present case the foot area with which the formwork chamber wall is fastened to the base frame la is formed in such a way that the pivoting movement, ie the the swiveling range to be covered is smaller.
  • the standard middle group lb is with the Base frame connected rigidly and thus serves as a stopping point.
  • the precast concrete part 3 is formed in the present case with only flaccid reinforcement, which in particular comprises an inserted reinforcement cage that is prefabricated outside the formwork form but prefabricated on site.
  • the subsoil 4 is only a well-compacted floor area on the construction site near the place where the precast concrete parts to be manufactured in the battery formwork 1 are to be built. .
  • the base frame la is formed in such a way that several base frames can be strung together, which can be achieved by screwing (not shown). These are solved between the construction sites, but are fixed during many cycles. If necessary, elements can be provided which bring about additional stabilization. If formwork chamber side walls with a supporting structure are attached to the base frame over the screwed joint, considerable stabilization already results. Couplings between the side walls, which are provided to prevent the passage of concrete, can be released for stripping in order to be able to better handle and fold down the walls.
  • the invention is used as follows:
  • the battery formwork elements are brought to the construction site by truck and unloaded there.
  • a corresponding position and size of the base plate elements 1 a and the formwork chamber are then used for the first precast concrete parts.
  • mer walls 2b provided. It should be mentioned that this step can already take place in the workshop.
  • the end faces (not shown) are assembled and the outer walls are folded down.
  • the reinforcement cages are manufactured and moved laterally into the battery formwork arrangement.
  • a multifunction device such as a mobile, in particular all-terrain, portal crane can be used, which is particularly preferred in order to be able to avoid the use of expensive cranes by a simple device.
  • the side wall is folded up, which can also be done with machine support.
  • the threaded spindles 5 are used to ensure that the sides do not easily unfold when pouring liquid concrete.
  • concrete is poured directly from a truck mixer, ie without pumps or the like, to the required height and waiting for it to harden.
  • the threaded spindle After hardening, the threaded spindle is actuated in a relaxing manner, whereby the side walls separate from the precast concrete element while overcoming the adhesive forces. This is done separately on the inside and outside of the formwork chamber. To do this, a threaded spindle can pull the inner wall of the formwork chamber against the middle group.
  • the battery circuit arrangement does not have to be moved in the next work cycle. It is therefore a battery circuit arrangement for a construction site, which is stationary at the construction site over a large number of cycle sequences.
  • the side walls and bottom walls are dismantled if necessary and the procedure is repeated for a second precast concrete part width until all precast concrete parts are manufactured for the construction site and the battery circuitry arrangement, if necessary disassembled, can be moved to another construction site.
  • Adjustments in the height of the precast elements are simply formed by upper triangular strips at a new height, which also represent the new pull-off level. Adjustments in the length of the prefabricated parts are achieved simply by converting the face formwork.
  • Fig. 3 shows that different cross-sectional shapes are to be manufactured.
  • a conical cross section with a lintel can be produced as is known, but e.g. also an exactly rectangular or otherwise at least section-free cross section.
  • Fig. 3 further shows that, for example by the provision of bracket bands, more complicated cross sections, such as those with a T cross section, can be produced. It should be noted, however, that regardless of the principle of manufacturability, the one shown in FIG. 3d is preferred to that of FIG. 3c.
  • FIG. 4 shows detailed solutions of the wall assemblies.
  • An arrangement is shown on the left in FIG. 4a, in which the uprights and the longitudinal beams of the supporting rib structure of the wall lie in one plane, while on the right-hand side the uprights are arranged in a plane further away from the precast concrete element than the longitudinal beams.
  • the arrangement in which the uprights and the longitudinal beams of the supporting rib structure of the wall lie in one plane is preferred because the overall width of the arrangement is smaller. In view of the fact that the maximum possible width of the formwork is limited by the portability, but nevertheless a large width is desired in order to be able to manufacture concrete parts inexpensively, there are overall advantages.
  • sealing elements are arranged in the joint area of formwork skins in the case of elements coupled to one another can and that separating areas must be provided between forehead-to-forehead precast concrete parts.
  • FIG. 4b shows a detail of a floor formwork skin. As can be seen, their end area lies with the in the formwork position folded formwork wall under the formwork wall. Since the formwork wall extends over a certain area of the formwork floor, different widths of precast concrete parts can be produced with one and the same formwork floor, which reduces the otherwise required formwork floor waste.
  • Fig. 5 shows how the battery folding formwork looks when viewed from above, whereby the individual walls, referred to as inside / outside walls with the addition “left” or “right” can be clearly seen, as well as the stiffly connected stopping point connected to the floor assembly the actuator attack is provided.
  • Fig. 6 shows again a folding formwork battery variant in more detail. Recognizable here are the manually operated actuator spindles for the tie rods / relaxation as well as the bottom formwork panels that can be pushed in as explained above, the rigid central areas and the arrangement of formwork skins and support structures.
  • Fig. 7 shows how the formwork battery can be widened without impairing the road transportability by using an extension BR, which is releasably provided on the construction site on the base frame, for example by screwing.
  • widths greater than the 2.4 m width that can be easily transported can be realized.
