Definitions

  • the present invention relates to a method and an apparatus for producing a one-piece precast concrete element.
  • formwork When concreting prefabricated parts, formwork is usually filled with concrete from above.
  • the concrete falls from a certain height from above into the open formwork, possibly also on a reinforcement arranged in the formwork.
  • the concrete To fill all cavities of the formwork, the concrete must be mechanically compacted, for example vibrated.
  • SVB flowable self-compacting concrete
  • SVB flowable self-compacting concrete
  • the concrete rolls around and vents itself automatically without the use of mechanical energy.
  • Self-compacting concrete can be conveyed by means of a pump in the formwork. Again, the filling of the concrete is done from above into the open formwork, for example by a hose or pipe, the lower end is always held in the already filled concrete and is pulled up with increasing filling height, in this way as little air in to introduce the concrete.
  • Shuttering smooth surfaces in visual quality or profilings on all sides can not be produced with the known concreting methods or at least not in sufficient quality.
  • Another major disadvantage of the conventional method is that, for example, room modules with bottom and thin side walls can only be concreted upside down, ie, with the floor upwards, and thus turned into the transport or installation position only after complete hardening of the concrete have to. Accordingly, the whole formwork is blocked.
  • US Pat. No. 6,395,213 B1 discloses a method of making a precast concrete element comprising the steps of: providing an empty formwork comprising bottom formwork, side formwork, a displacer, and a flameproof cap terminating the formwork at the top; Pressing in flowable concrete in the area of the floor formwork; continuous filling of the formwork with concrete, which rises under pressure from bottom to top, until the cavities of the formwork are completely filled; Solidification of the concrete in the formwork; Remove the cover, the displacement body and the side formwork so that at the end the freshly concreted prefabricated part only stands with the bottom on the bottom formwork.
  • US Pat. No. 6,395,213 B1 also discloses a device and a method for producing a precast concrete element, according to the preamble of claims 1 and 7, comprising a cap which closes pressure-resistant upwards formwork, and at least one closable inlet for flowable concrete arranged in the region of the bottom formwork. In the cover openings are provided, can escape from the inflowing concrete displaced air from the interior of the formwork in the environment. These holes are flush with the horizontal top of the cap.
  • EP 0 382 536 A1 describes a method and apparatus for making articles from a liquid, solidifying material.
  • the device comprises a mold composed of two halves enclosing a cavity, a gasket for pressure-tight sealing of the mold to the atmosphere and an inlet for the liquid material.
  • a vacuum port is also provided to create a negative pressure in the mold before the liquid material is filled.
  • FR 2 619 047 discloses an apparatus for injecting concrete into a mold consisting of two halves.
  • the concrete is filled from a arranged above the mold funnel under pressure.
  • Top-mounted on the form of control (structs) allow to control the completion of the filling of the mold with concrete.
  • an empty formwork is first provided, which consists of bottom formwork, side formwork, displacement body and a cap.
  • the formwork is thus sealed off at the top. It is also provided at least one open riser, which projects beyond the formwork.
  • the concrete in the formwork is allowed to solidify. Subsequently, the cap and the side mold are removed and the displacer pulled out. At the end, the freshly concreted finished part stays with the floor, ie in the installed position, on the lower formwork.
  • the method according to the invention is very well suited for the production of a room module which comprises at least one floor and side parts integrally formed thereon and can be used to create a simple building, for example a garage or a small house. But it can also be any other components, for example, flat, rod-shaped or spatial components are manufactured with and without openings or recesses.
  • the formwork comprises a displacement body in the form of a removable inner core whose distance from the bottom formwork and the side formwork determines the thickness of the floor or side walls of the room module to be concreted.
  • the pressure with which the concrete is introduced into the formwork thus serves not only to convey the concrete but also to distribute it within the formwork.
  • the formwork must be sufficiently pressure-stable and, in particular, also have a sufficiently pressure-resistant cover to the top.
  • the pressure prevailing in the formwork when filled with concrete is composed of the geodetic concrete pressure, the friction and adhesion resistance as well as an additional operating pressure, which is necessary for the inflowing concrete to flow through narrow passages and into all angles and the reached the highest cavities in the formwork sufficiently fast.
  • Another great advantage of the concreting process according to the invention is the high quality of the exposed concrete surfaces that can be achieved therewith.
  • the use of flowable concrete and its air-poor distribution within the formwork under pressure results in smooth walls in fair-quality concrete and can be any profiles, for example, at the bottom of the soil, if necessary.
  • the flowable concrete is pressed from below into the formwork until the formwork is completely filled and beyond a projecting concrete column has formed in the riser. Subsequently, the supply of concrete is turned off. The concrete column in the riser begins to sink to the extent that the concrete in the formwork settles due to its own weight. As soon as the concrete column in the riser pipe no longer sinks, the connection to the formwork is sealed off. This procedure ensures that all cavities within the formwork are filled with concrete.
  • the riser thus works as a pressure equalizing vessel with memory function.
  • the method according to the invention is characterized in that the filling process can be carried out at high speed.
  • Tests have shown that filling speeds of up to 40 l / min with a delivery line with a cross section of 50 mm pose no problem and also have no negative effects on the quality of the exposed concrete surface, even with very narrow formwork geometry.
  • the prerequisite for such high filling speeds is the use of a suitable fresh concrete.
  • SCC self-compacting concrete
  • SCC self-compacting concrete
  • good-flowable SCC of the flour-type which is characterized by an excess proportion of flour meal.
  • a device which serves to carry out the method according to the invention comprises a sufficiently pressure and deformation-resistant formwork, which consists at least of bottom formwork, side formwork and a displacement body.
  • a pressure-resistant cover is provided, which closes the formwork at the top.
  • the device according to the invention also comprises an open riser pipe, which projects beyond the formwork and is connected to the latter via a closable opening.
  • the device designed in this way allows the introduction of flowable concrete in the area of the bottom formwork and the continuous filling of the formwork with concrete, which rises under pressure from bottom to top in the riser until the cavities of the formwork are completely filled with concrete and a supernatant Concrete pillar has formed in the riser.
  • closable inlets for concrete along the side mold are distributed so that the concrete column rises as evenly as possible in the formwork. This is supported by the fact that preferably also several pressure equalization vessels are provided, which are also distributed along the edge of the side mold.
  • a high-pressure concrete pump is preferably used, which is in fluid communication with the closable inlets.
  • the pressure generated by the pump not only serves to transport the concrete, but is also responsible for the uniform distribution of the concrete within the formwork.
  • the concrete is pumped via a branched system of hoses and pipes to the inlets of the formwork.
  • the riser pipes are made of transparent material, in particular plastic, so that the height of the concrete column can be observed.
  • obturator is for example a horizontal disc with an eccentrically arranged recess which can be rotated by hand via a corresponding opening in the cap.
  • the riser is detachably connected to the top of the cap and decoupled. This makes it possible for the riser pipe to be quickly separated from the formwork cover and for the residual concrete contained therein to be dumped before it cures.
  • Fig. 1 is a bottom form 1 to see. This is also designed as a transport pallet and has on its upper side a contouring 2, the negative is to impress in the bottom of the space module to be produced.
  • Fig. 2 is a side formwork 3 placed on the bottom formwork 1.
  • the side mold 3 is composed of a number of side panels.
  • Floor formwork 1 and side formwork 3 define a rectangular parallelepiped.
  • the height of the side formwork 3 corresponds to the height of the side walls of the room module to be concreted.
  • an inner core 4 is introduced from above between the walls of the side mold 3.
  • the inner core 4 also has the shape of a rectangular parallelepiped whose dimensions are somewhat smaller than the clearances between the respective opposite walls of the side mold 3.
  • the inner core 4 On its upper side, the inner core 4 carries a number of parallel cross member 5, which survive right and left.
  • the inner core 4 is lowered gently close to the bottom formwork 1, so that it fills most of the space formed by the bottom formwork 1 and the side formwork 3.
  • Fig. 4 is the inner core 4 completely inserted into the side mold 3.
  • the lateral projections of the cross member 5 sit on top of the side mold 3 and keep the inner core 4 characterized in a defined small distance from the bottom formwork 1 (cf. Fig. 1 . Fig. 2 ). So that the inner core 4 does not float during concreting, the cross member 5 are firmly connected by means of fastening screws 6 with the side panel 3. As a result, the side formwork 3 is stiffened at the same time. Between the inner core 4 and the side wall 3 remains a running around vertical side gap 7, which determines the thickness of the side walls of the space module to be produced. So that the inner core 4 can be easily lifted out of the side formwork 3 again after concreting, it is designed as a shrink core, that is, its outer dimensions can be reduced with respect to the finished part to be concreted.
  • FIG. 4 the formwork consisting of floor formwork 1, side formwork 3 and inner core 4 is still open at the top, namely in the area of the side gap 7. According to FIG Fig. 5 This side gap 7 is now closed by means of a hinged cap 8. Thus, a completely closed formwork is provided.
  • each inlet 9 is connected by a short tube 10 to a conduit 11 leading to a high pressure concrete pump (not shown).
  • the inlets 9 are distributed at regular intervals along the outside of the side mold 3.
  • Each inlet 9 has its own obturator, so that the inlets 9 each open and close independently.
  • risers 12 are placed on the closed cap 8 risers 12 are placed. At the top, these risers 12 are open, below they are connected via a small closable opening with the otherwise pressure-tight closed interior of the formwork in combination.
  • Fig. 5 is indicated by arrows that flowable self-compacting concrete (SVB) is introduced in a split-flow through the conduit 11 via the hoses 10 and the inlets 9 in the formwork.
  • SVB flowable self-compacting concrete
  • the concreting can be controlled so that first the space between the bottom mold 1 and bottom of the inner core 4 is rinsed with concrete and then nachgef dirtender concrete as evenly as possible in the side gap 7 between the side mold 3 and inner core 4 (cf. Fig. 4 ) goes up. Only when all cavities in the formwork are completely filled with concrete and the concrete is also raised in the risers 12, the concrete pump is turned off and all the inlets 9 are shut off. Inlets 9 and risers 12 are uncoupled and the corresponding openings closed form smooth as long as the concrete is liquid.
  • the cap 8 is removed. After loosening the mounting screws 6, the inner core 4 can be lifted upwards, wherein the cross member 5 stand out from the top of the side mold 3. Previously, the inner core 4 was shrunk to disengage from the adjacent concrete wall. In Fig. 6 the inner core 4 is already pulled a piece upwards. There, where was at the empty formwork of the side gap 7 (see. Fig. 4 ), the side walls 13 of the freshly concreted space module have now formed.
  • the room module made of one piece of concrete comprises, in addition to the sidewalls 13, a flat floor 14 which is monolithically connected to the sidewalls 13.
  • openings 15 are provided for doors and windows. Even if the concrete is not fully cured, the floor formwork 1 can be transported away together with the room module resting on it. All surfaces are smooth and have fair-faced concrete quality.
  • the scale enlarged picture of Fig. 8 allows a look inside the formwork.
  • the inner core 4 is shown vertically cut. It can be seen the side gap 7 between the inner core 4 and side mold 3 and the cap 8, which closes the formwork towards the top.
  • the cap 8 is formed as a flat sheet of steel and is with its outer (in Fig. 9 left) edge pivotally attached to the top of the side mold 3. With its opposite edge, the cap 8 lies on the inner core 4, so that the side gap 7 is covered.
  • the closed lid 8 is held closed by a latch 16 so that it withstands the pressure acting from below of the concrete rising in the side gap 7.
  • the attached to the outside of the closed cap 8 riser 12 is made of transparent plastic, so that it can be seen whether and how high the concrete column has risen in the riser 12.
  • a flange 17 serves to quickly connect and disconnect the riser 12 to and from the cap 8 (see. Fig. 9 ).
  • Knockable wedges 18 press the flange 17 firmly on top of the cap 8.
  • the flange 17 has a small round opening 19.
  • a disc 20 is horizontally rotatably mounted, which has an eccentric bore 21. By means of a radially outwardly projecting lever 22, the bore 21 can rotate over the opening 19, so that concrete can rise from below from the closed formwork in the riser 12. By turning back the disc 20, the opening 19 can be closed again to interrupt the connection between the riser 12 and the interior of the formwork. After removal of the wedges 18, the completely or partially filled with concrete riser 12 can be decoupled from the cap 8 to empty it before the concrete has set.
  • Fig. 10 In principle, the same formwork is shown as in Fig. 5 but horizontally cut and not to scale.
  • the hollow core 4 fills most of the interior of the formwork except for the side gap 7.
  • the formwork Towards the top, the formwork is closed by the cover 8 in a pressure-tight manner.
  • Separately lockable inlets 9 are arranged on the right and left in the lower region of the side mold 3.
  • the supply of fresh concrete can be controlled.
  • a riser 12 are placed on the right and left, which are in fluid and pressure communication with the interior of the formwork.
  • the connection can be opened or closed by means of shut-off valves 24. Above the risers 12 are open, so are in contact with the atmosphere. In the open state, the riser tubes 12 function as pressure equalization vessels.
  • the formwork is empty.
  • the filling valves 23 at the inlets 9 are all closed, whereas the shut-off valves 24 of the risers 12 are opened.
  • the filling valve 23 is now opened on the left side, whereupon flowable self-compacting concrete (SVB) flows at high speed on the bottom mold 1.
  • the displaced by the inflowing air can escape through the open risers 12 upwards.
  • the viscous concrete does not distribute itself uniformly. Rather, the inflowing concrete accumulates in the area behind the left inlet 9 and begins to rise first on the left side in the side gap 7 to the top.
  • the bottom mold 1 and the inner core 4 bottom gap 25 is flushed from left to right with the liquid concrete. It should be noted that the bottom gap 25 is in truth much narrower than shown in the drawings. Therefore, it requires a fairly high pressure, so that the concrete is pushed through the bottom gap 25 therethrough.
  • Fig. 11 the bottom gap 25 is already completely filled with concrete.
  • the left part of the side gap 7 is filled to about one third with concrete, whereas almost no concrete has arrived on the left side.
  • Fig. 12 shows a state in which the concrete column on the left side has almost reached the top of the side shell 3, while the side gap 7 is filled on the right side only about two-thirds.
  • the still fresh concrete is set. This can be seen from the fact that the concrete column in the risers 12 drops slightly. This can be compensated by subsequent flow of the concrete contained in the nearest riser 12.
  • the risers 12 thus not only serve the pressure equalization or the construction of a controlled backpressure, but at the same time also provide storage for the still flowable concrete and thereby ensure that even after settling of the concrete really all voids of the formwork remain completely filled. Only when the concrete column no longer sinks in the riser tubes 12, the associated shut-off valves 24 are closed and thus the connection to the interior of the formwork is interrupted. The risers 12 can then be dismantled, emptied and cleaned.
  • the method has hitherto been explained using the example of a room module with side walls and monolithically connected floor.
  • the proposed method is by no means limited to this. It is equally possible to produce also room modules with floor and ceiling by means of the method according to the invention using the device according to the invention from a piece of concrete. It is also possible to introduce a plurality of inner cores at a distance in the formwork, so that monolithic center walls arise in the room module.
  • solid bodies with very simple geometry, such as wall elements, round or square tubes, columns and blocks can be manufactured efficiently and in the best quality using the proposed method.
  • Fig. 14 explains the production of a room module with floor, side walls and in addition a ceiling as a one-piece concrete precast.
  • the formwork consists of bottom formwork 1, side formwork 3 and a cover 8 ', which, however, covers the entire side formwork 3 here.
  • the inner core 4 ' is here arranged centrally in the interior of the formwork, so that apart from the bottom gap 25, a ceiling gap 26 remains between the upper side of the inner core 4' and underside of the cover 8 '.
  • the inner core 4 ' can be pulled out later to the front.
  • FIG. 14 Formwork shown is filled with well flowable self-compacting concrete, which rises under pressure from bottom to top.
  • the filling process is assisted by an additional inlet 9, which is arranged on the left side of the side mold 3 just below the cap 8 '.
  • Figure 14 is to see a state in which the concrete column has risen on the left side already in the left riser 12 and thus reached its maximum, while on the right side below the right riser 12 still air, especially in the ceiling gap 26, located.
