Definitions

  • the present invention relates to a concrete ceiling for round containers with a diameter of at least 5 m consisting of several, the upper opening of the round container covering semi-finished parts as substructure and reinforced, poured over concrete.
  • the invention further relates to the process for the manufacture of such concrete ceilings and as an intermediate product, the semi-finished part for the production of Concrete ceilings.
  • Round concrete containers are used primarily for industrial, municipal and agricultural water supply and sanitation built, such as sprinkler centers and Water storage tanks as well as rain pools, rain overflow pools, Rain cyclones, fire water tanks, etc. They point in the general diameter of more than 5 m and are now also built in diameters from 30 to 40 m. Concrete ceilings for such round containers have been built by Construction of a corresponding formwork in the otherwise finished Round concrete container, introduction of reinforcing iron and pouring the ceiling. Unless the round concrete container has a larger diameter have and thus the ceilings also larger spans such bridges can no longer be self-supporting be built, but need for medium sizes at least one permanent central support column, with larger ones Diameters even several support columns between the middle and the wall of the round concrete container.
  • the invention has therefore set itself the task of concrete ceilings for round containers with a diameter of at least 5 m of semi-finished parts available as a substructure make which from special semi-finished parts as well reinforced, poured over concrete.
  • the semi-finished parts later as much as possible on the statics of the Contribute to the overall ceiling and thus the need for reinforcing bars and reduce concrete.
  • the manufacturing process should the concrete ceiling at least on site of the round container simplified, shortened and cheaper, with the Logistics, especially regarding formwork elements and semi-finished parts should be designed as cheaply as possible.
  • precast concrete column For medium-sized round containers that have a central support need, according to the invention in the middle of the Container set up a precast concrete column.
  • This precast concrete column is preferably on an adjustable height Adjustment point placed and is concreted in a quiver or articulated on the base plate.
  • the semi-finished parts - later as much as possible - for Statics of the overall ceiling contribute and thus installation of reinforcing bars and reduce concrete on the construction site.
  • the precast concrete column preferably has one at the upper end Mushroom head with an all-round rise as a storage surface on. This configuration leads to a support of the semi-finished element on the mushroom head that also have slight deviations allowed from right angle. It is even possible targeted a certain slope of the concrete ceiling from the inside to the top outside, which is used in a number of applications is considered advantageous.
  • the precast concrete column has over-concrete in the middle a column extension, which allows the surface after casting, smoothly peel off with a scraper while controlling that everywhere and the sufficient amount of over-concrete as evenly as possible was applied.
  • An essential feature of the concrete ceiling according to the invention is the design of the semi-finished parts with the L-shaped load-bearing reinforcements below the round outer plate and outside one of the two cut edges of the cover plate, this reinforcement of the cut edge over the cut edge protrudes and thus the support for the adjacent can not form reinforced outer edge. Any of these reinforcements below one of the two cut edges thus in the finished concrete ceiling to support both Cut edges of the cover plate.
  • This configuration is statically much cheaper than a structural reinforcement underneath both cut edges of the cover plate, since doing so two reinforcements arise in the immediate vicinity would who are not connected and therefore at Forming an obvious vulnerability from above would.
  • the configuration according to the invention is thus static particularly cheap and on top of that in terms of material requirements of reinforcing iron and concrete are significantly superior to other solutions.
  • the semi-finished elements according to the invention continue on the round outer edge have a circumferential parapet this causes undesired lateral drainage and overflow of over-concrete avoided. It is also no additional Formwork necessary.
  • the height of the parapet is simultaneous the height and quantity of the over-concrete to be poured is determined and limited. The height of the parapet must therefore be coordinated for example with the column extension in the middle of the Prefabricated concrete column. When building round containers with little Diameter and use of a platen can do this again have a metal bar bent centrally to form an eyelet. This facilitates transportation and insertion the platen, and at the same time can be on her and with her Help be marked up to what height the over-concrete is too is pouring.
  • a preferred embodiment of the reinforcement below the cut edge of the cover plate has one or more ventilation openings running parallel to the outer edge. By these openings can also be air from flow one segment to another when the water level is above the lower edge of the reinforcements rises. Furthermore it is possible, cables and measuring lines through these ventilation openings to lay and thereby at the same time in easier Way to attach to the bottom of the concrete ceiling.
  • the blankets according to the invention compared to the round container a certain excess.
  • This supernatant can then also be provided with a water nose, which above all with free-standing tanks, rainwater runs off directly avoids on the outer wall of the round container. This otherwise leads to quite unsightly rain drainage surfaces that can discolor quickly and at least look ugly.
  • the method according to the invention for producing the concrete ceiling generally takes place in that in the middle of the round container either a height-adjustable formwork stand and an application plate or a height adjustable insert Ready-to-use concrete column and, if necessary, further precast concrete columns and finished beams, then the semi-finished parts used, covered with reinforcing iron and with Pour over-concrete, but after setting only the existing formwork stand in the middle Will get removed.
  • the semi-finished parts used according to the invention for the production of concrete ceilings are dimensioned, if possible, that they have a size of 2.35 m to 2.50 m. You can then be transported on normal trucks will. But it is in principle and in particular for larger containers it is also possible to use semi-finished parts, the outer edge of which is up to 3.50 m wide. This can then at least on special transporters from the Manufacturing site transported to the place of use will.
  • the number of semi-finished parts required and their dimensions depends on the one hand on the diameter of the Round container and on the other hand of the possibilities of the rational Transport.
  • the requirements for the statics of the ceiling can if necessary by dimensioning the load-bearing Reinforcements are taken into account.
  • it is possible according to the invention with a relatively small number of semi-finished parts has a relatively wide range of requirements to meet the concrete ceilings for the round containers. Again, this is primarily a question of manufacturing costs, the logistics as well as the not inconsiderable costs for the Formwork elements for the production of semi-finished parts.
  • precast concrete columns with a mushroom head and possibly other precast concrete columns and prefabricated beams are less critical.
  • the fact that the precast concrete columns in the middle the container can be made height adjustable, can inevitable height fluctuations between the floor of the round container and the desired lower edge of the concrete ceiling can be easily compensated. It is even beyond that possible, a slope by the height adjustment of the ceiling to give to the outside without having to change the column dimension.
  • the concrete ceilings according to the invention can, depending on the purpose be built above ground and underground. After this These concrete ceilings can also be easily set a higher layer of soil and if necessary also expanded as a parking lot or driveway will.
  • the improved statics compared to conventional concrete ceilings gives a long-term guarantee of durability.
  • reinforcing bars can be influenced.
  • Reinforcing iron is particularly suitable after casting to connect the over-concrete with the semi-finished parts.
  • reinforcement bars made from reinforcement protrude below the cut edge of the cover plate and thereby a stronger connection of the reinforcement with the set over-concrete.
  • Figure 1 shows a top view of a concrete ceiling with a support plate.
  • Figure 2 shows a semi-finished part as well as cuts and views this semi-finished part.
  • Figure 3 shows in cross section a round container with a such a concrete ceiling.
  • Figure 4 shows a top view of a concrete ceiling for medium Diameter at which the platen is replaced by a precast concrete column.
  • Figure 5 shows the crucial parts of a cross section Round container with such a concrete ceiling.
  • Figure 6 shows a top view of a concrete ceiling for very large Diameter at which between the center and the wall of the Container in the polygon further precast concrete columns and precast beams available.
  • FIG. 7 shows the essential parts of a cross section such round container with concrete ceiling.
