FORMWORKING DEVICES AND METHOD FOR PRODUCING MONOLITHIC CONCRETE CASTINGS

description

The invention relates to formwork devices for producing monolithic concrete castings and a method for producing monolithic concrete castings.

To concreted concrete structures, such as underground tanks, cisterns, L-Mauem, garages, multi-channel pits such. As small sewage treatment plants or other buildings made of concrete, it is necessary according to the prior art to cast a foundation on site and later build the building on it. Such a procedure is described for example in DE 3700159 A1. Concrete plants supply prefabricated components, which are assembled on site with a high level of technical effort. Considering that the loading area of a standard truck is only 2.80 m wide, or that a 1 meter concrete block spacer for a 3 meter diameter cistern weighs almost 2 tons, it is obvious that the volume of such concrete paving is very limited. In addition, a very expensive loading technology is required on site and the use of highly qualified workers who need to make the tailor-made assembly of the individual parts.

From DE-OS 2159960 a container made of concrete, which serves in particular as an underground tank for fuel oil, known. Such a ground tank consists of at least two interconnected curved concrete shell parts and a corresponding number of internal walls made of plastic. At the junction of the two concrete shell parts, the wall of the plastic shell is extended and connected to the other concrete shell part tensile strength. In addition, the adjacent concrete shell parts can be bonded together by gluing.

Such underground tanks can be built only with a high level of technical use in easily accessible places. However, the tension-resistant connection of the concrete shell parts alone does not guarantee a tight connection, which is why the bonding takes place. However, splices are always subject to an aging process, so that it can not be ruled out that such underground tanks are leaking over the years and fuel oil can escape into the surrounding soil, which is a significant environmental pollution.

Also known is the monolithic production of concrete constructions. For example, DE 32 02 336 C3 describes the industrial production of a monolithic concrete casting in the form of a prefabricated garage open to one side. On an inclined plane, a track for roller pallets is laid with an inclination angle of about 20 °. It leads up to an erected on the inclined plane scaffolding, which carries a rigid inner formwork, the inner formwork can also have movable formwork parts. Short-stroke cylinders are connected to a frame, which closes the outside of the inner formwork and of an outer formwork limited form space on its front side. The outer formwork for the garage floor forms the rolling pallet. Each additional panel corresponds to the size of a garage wall, only the slab formwork is made in two parts. The formwork panels are mounted in steel frameworks and form a five-sided closed space body. All moldings and walls are inclined, none of these parts are horizontal. Via a pour-in pumping system, liquid reinforced concrete is dropped into the mold, which fills from the top and is provided on the riser to prevent inclusions of air and / or water. After completion of the garage concrete casting, the slab formwork is swiveled upwards via a lever mechanism and brought into the descaling position. Then the two outer panels are driven off. By pressing the cylinder, the winch is lowered and the inner formwork is stripped off. Thereafter, the rolling pallet is moved over a swivel stage in the horizontal.

Such a complex design for a shuttering device is only suitable for the industrial production of concrete constructions. It is not suitable for the production of monolithic concrete castings at its place of use.

The invention has for its object to provide cost-effective formwork devices for producing monolithic concrete castings, which make it possible to manufacture concrete castings directly at their place of use in hard to reach places and ready-built land made of concrete in one operation on the ground, without previously a foundation has to be built. This object is achieved by the features listed in claim 1.

The formwork apparatus according to the invention is formed from a multiplicity of formwork boards or formwork panels, wherein outside formwork boards are connected to one another in such a way that they form a closed geometrically defined outside formwork that is fixedly secured in the ground or on a prepared ground and interior formwork boards are connected to one another in this way. that they form a closed geometrically defined inner wall, which is spaced from the outer formwork by the wall thickness of a monolithic concrete casting to be produced. The bottom end portions of the inner formwork boards are connected by a shuttering board floor, wherein the inner wall forms the inner formwork with the formwork board floor. The inner formwork boards are designed to be at least the wall thickness of the bottom of the monolithic concrete casting to be cast shorter than the outer formwork boards. The inner formwork is attached to the outer formwork hanging directly or indirectly freely. Advantageous developments of the invention are the subject of the dependent claims.

For indirect attachment of the inner formwork to the outer formwork, at least one transverse bar is screwed, for example, above the floor-distal end portions of the outer formwork boards, and the inner formwork is attached to this crossbar hanging freely.

The free-hanging inner formwork ensures that no spacers are required between the outer and inner formwork in order to keep the outer formwork of the inner formwork within a defined distance, which corresponds to the wall thickness of the finished concrete casting. If at least two opposite sides simultaneously filled concrete from above into the formwork device, this flows smoothly between the formwork boards in the direction of soil and is evenly distributed there. The soil should first be solidified by means of a vibrator and covered with a plastic film, so that the water can not flow out of the concrete too quickly and solidification occurs only when all voids between the inner and outer formwork are filled with concrete. There is no danger that air bubbles or water bubbles will form in the concrete, as the shuttering boards are connected with each other in such a way that air and / or water escape through the outer shuttering and seep into the ground can. For concrete wall thicknesses of approx. 15 cm, smaller air bubbles and / or water bubbles play no role whatsoever in the tightness of the container.

Concrete castings produced with the formwork device according to the invention can be, for example, water reservoirs for agriculture in the form of cisterns or endless cisterns. Large tanks of 50,000 liters or 100,000 liters capacity can be manufactured cheaper up to one-third of the usual market production costs. Also, a cuboid design allows better space utilization than a known from the prior art spherical cistern. With the formwork device according to the invention further underground tanks for storage of liquids or solids, such as fuel oil tanks or pellet underground tanks can be built. But also aboveground buildings can be produced without having to cast a foundation beforehand, for example L walls. Very well feasible is the construction of L-walls on a hillside.

The invention will be explained in more detail below with reference to the exemplary embodiments schematically illustrated in the drawings. Show it

The formwork apparatus 1 according to the invention according to FIG. 1 is used to produce a cistern 19. A plurality of formwork boards 3 are detachably connected to each other in a known manner, for example by metal bolts or screw connections. A variety of outer formwork boards 4 forms the outer formwork 5, which is fixed secured in the soil 6 secured. The soil 6 should have a certain strength, so that it can not lower in an inadmissible manner after completion of the concrete casting 2. Otherwise, the soil is to be solidified in a known manner with a vibrator before starting the formwork. The securing of the outer formwork 5 in the soil 6 is carried out by ground anchor 17th

Shuttering boards 3 have basically smooth surfaces on their insides in the direction of the concrete wall. At the back there are struts, which allow a connection of the shuttering boards 3 with each other.

As a rule, cisterns 19 are built underground. It is excavated an earth hole that is at least 1 meter wider than the outer cross section of the outer formwork 5, so that a fitter can mount the outer formwork boards 4 easily and dismantle after completion of the concrete casting 2 again. The outer formwork 5 of the cistern 19 according to the invention has in a first

Embodiment of FIG. 2 on a square in plan view shape. But it can also be made rectangular or circular or have the shape of a polygon.

In the same or approximately the same geometric shape is then carried out in the interior of the outer formwork 5 from inner formwork boards 7, the assembly of the inner wall 8, wherein the inner formwork boards 7 are made shorter by at least the wall thickness 9 'of the bottom 16 of the cistern 19 than the outer formwork boards 4. The inner formwork boards 7 of the inner wall 8 are connected to each other at their bottom end portions 10 by a shuttering board floor 11. The result is an upwardly open inner formwork 12. The opening 21 of the inner formwork 12 is approximately 80 cm in this embodiment. So that after completion of the cistern 19, the inner formwork 12 can be dismantled again and the inner formwork boards 7 lifted out of the cistern 19, the rectangular inner formwork boards 7 should not be wider than 95 cm. For the production of the bottom 16 of the cistern 19 opposite opening 21, the outer formwork 5 and the inner wall 8 of the inner formwork 12 are made in two parts. The inner wall 8 is formed by longer, rectangular inner shuttering boards 7 and shorter, upwardly tapering trapezoidal inner shuttering boards T, the angle 23 between the inner shuttering boards 7, T being between 110 ° and 130 °, preferably 120 °. The outer formwork 5 is likewise designed in two parts and is formed by longer, rectangular outer formwork boards 4 and shorter, trapezoidal outer formwork boards 4 ', wherein the bend 23 between the outer formwork boards 4, 4' is likewise preferably 120 °. In the embodiment of FIG. 2, the assembly of the outer formwork 5, however, with two arranged transversely to one longitudinal side, rectangular and over an entire longitudinal side reaching outer formwork boards 4 ', which are also attached at an angle of preferably 120 ° to the outer formwork boards 4.

After completion of the inner formwork 12, at least one transverse bar 14 is laid over two opposite outer formwork walls and screwed to the outer formwork 5. In the first embodiment according to Figures 1 and 2, there are two crossbars 14. The bottom distal end portions 22 of the inner formwork 12 form cross members 15, where the inner formwork 12 is raised via a lifting device and secured by preferably screws 27 or clamps or the like to the crossbar 14 , In the embodiment of FIG. 2, the cross member 15 of the inner formwork 12 and the crossbar 14 are arranged directly above one another and spaced from each other by the wall thickness 9.

Two cross member 15 of the Innenschaiung 12 are each connected to a crossbar 14 by screws 27 or clamps or the like. On the outer formwork 5 can be screwed further crossbar 28 on which, for example, concrete filling devices (not shown) are arranged. The filling of the formwork device 1 with concrete is preferably carried out simultaneously from two sides.

In a second exemplary embodiment according to FIGS. 3 and 4, an underground tank 18 is shown, in particular for the storage of pellets with a shuttering device 1 according to the invention. The shuttering board floor 11 is here not rectangular and one piece but obtuse and attached in two parts to the inner wall 8. The shuttering board floor 11 is formed by shorter bottom formwork boards 11 ', which are butted together at an obtuse angle. In this way, the required for a good air circulation pellet tank shape. Between outer formwork 5 and inner formwork 12 plastic pipes 24 are attached to defined locations that remain free of concrete and remain after completion of the concrete casting in concrete casting 2 and, for example, the ventilation and / or air circulation within the earth tank 18 are used. To the shorter inner formwork boards T more short inner formwork boards 7 "are added, which form the opening 21 of the concrete casting 2 and meet when lifting the fully assembled inner formwork 12 perpendicular to the crossbar 14 and bolted to it.

Alternatively, the cross member 15 of the inner formwork 12 with the ground away

End portions 13 of the outer formwork 5 ends directly above each other, as in a third. Embodiment shown in Figures 5 and 6. The shorter outer formwork boards 4 'are made so long that they directly touch the short inner formwork boards 7 ".The inner formwork 12 is fastened directly to the outer formwork 5 in a freely suspended manner and screwed with screws 27

However, this is not necessary since these parts have no supporting function and can be made so narrow that they prevent penetration of the concrete into the internal formwork 12, but not with the screws 27 It is within the scope of the invention to provide 5 more beams or metal rails to increase the stability with prefabricated boreholes for screwing to the cross members 15 on the bottom end portions 13 of the outer formwork. In a, fourth embodiment of FIG. 7 is a plan view of a cistern 19 made of concrete with a rectangular plan and a direct attachment of the outer formwork 5 to two cross members 15 of the inner formwork 12.

It is also within the scope of the invention to form outer formwork 5 and inner formwork 12 in a different geometric shape. For example, a plurality of cisterns 19 can be cast with a formwork device 1 according to the invention made of concrete, which are separated from each other, for example, only over a 1 meter high wall, so-called endless cisterns. In this way, for example, large drinking water reservoirs can be created in rain-poor areas in a quick and uncomplicated way.

In Fig. 10, another embodiment of a cistern is shown. The outer formwork 5 is secured here by three ring anchors 31, which are placed around the outer formwork against lateral stretching of the outer formwork 5. Most advantageously, the ring anchors 31 are arranged in the middle region and in the upper and lower end of the arranged perpendicular to the ground 6 outer formwork boards 4 and firmly clamped. To prevent the buoyancy when filling the formwork 5, 12 with concrete serve in addition to the Erdankem 17 posts 32, z. As steel, which are mounted slipping in the lateral soil 6 'of a well excavated Erdlochs.

An advantage of securing the outer formwork 5 by means of ring anchors 31 is that the opening 21 of the cistern 19 has a defined outer opening which does not change during or after filling with concrete. Thereby, the end portions of the crossbars 14, on which the cross member 15 of the inner formwork 12 are suspended and bolted, in the oblique bottom remote end portions 13 of the shorter outer formwork boards 4 'are fitted slipping resistant. An additional screwing the crossbeam on the outer formwork 5 can be omitted.

Commercially available formwork panels, eg Betoplan panels, which are smooth on their inner side and rough on the outer side, can be used as outer formwork boards 4, 4 'and inner formwork boards 7, 7', 7 " Metal struts bolted together in a conventional manner, and the side edges may be reinforced by metal plates and / or metal corners. It is within the scope of the invention that further support fuses for the outer formwork 5 are arranged in the outer region and / or for the inner formwork 12 in the inner region of the formwork apparatus 1. A support of the inner formwork boards 7 by an additional transverse and / or diagonal support against a widening of the inner formwork 12 may be required with increasing size of the concrete casting to be produced.

Not only concrete containers can be produced with the formwork apparatus 1 according to the invention but also monolithically cast L walls 20. In conventional concrete construction, the foundation is always first erected and then added the vertical wall. According to the foundation and L-wall are produced in one operation. In even soils are punctually in addition depressions (not shown) introduced into the soil 6 in order to prevent in this way a landslide of an L-wall on a slope. A formwork apparatus 1 for a monolithically produced L wall 20 is shown in a fifth exemplary embodiment in FIG.

The outer formwork boards 4 are releasably connected to each other and form a straight, vertical wall as outer formwork 5, which is secured with ground anchors. In addition, the outer formwork 5 can be secured in the lateral, excavated earth 6 'by supports 32 made of metal, wood or another stable material, s. also Fig. 10. The shorter inner formwork boards 7 form a parallel to the outer formwork boards 4 by the wall thickness 9 of the vertical wall of the L wall 20 spaced inner wall 8. The shuttering board floor 11 is divided into two parts in this embodiment, it is formed by different length Bodenschalungsbrettern 11 ' , A spacer 26, which is connected to the L-side lower end portion 25 of the inner formwork 12, secures the inner formwork 12 with respect to a constant distance of the outer formwork 5 and inner formwork 12 to each other and raises the top-heaviness the inner formwork 12. In the bottom end portion 13 is at right angles to the outer formwork 5, this across, arranged at least one crossbar 14 and bolted to the outer formwork 5. The pre-assembled inner formwork 12 is now lifted by means of a lifting tool to the wall thickness 9 'of the bottom 16 of the L wall 20 until the bottom end portions 22 of the inner formwork boards 7 touch the crossbar 14. Now, the inner formwork 12 is bolted to the crossbar 14 firmly. Alternatively, the crossbar 14 can also be mounted first on the inner formwork 12 and then on the raised end portion 13 of the outer formwork boards 4 lifted and bolted there.

Thereafter, the formwork device 1 is filled with concrete. It is advantageous if the floor-distal end portion of the inner formwork has an outwardly facing slope of about 2 °. The sloping upper edge ensures a slightly conical reinforcement of the L wall in its lower area and gives it more stability in terms of static. Once the concrete is solidified, outer formwork 5 and inner formwork 12 are dismantled and prepared for reuse.

With such a formwork device 1, L walls 20 can be erected on a slope, as shown in Fig. 9. For concreting on a slope, angle rails 30 are mounted as a termination with continuous mounting option according to the respective inclination or pitch angles of the terrain.

If instead of the L-wall 20 of FIG. 6, a U-wall, so a spacer 26 is not needed, since a U-shaped inner formwork is formed between two

Exterior formworks 5 hanging freely to the wall thickness 9 of the L-walls spaced from at least two crossbars 14 is held.

However, it is within the scope of the invention, the outer formwork 5 and the inner formworks 12 pre-cast concrete 2 pre-assemble or integrally form and only set up on site or use in the excavated soil with a crane and only to secure the inner formwork 12 to the outer formwork 5 hanging freely.

About 1 hour after completion of the concrete casting process, the setting effect is completed. It can now be poured more concrete. Too much poured concrete can be scraped off while the concrete is still soft.
