Definitions

  • the invention relates to the butt joint of highly loaded reinforced concrete prefabricated columns.
  • supports In the construction of high-rise buildings, it is customary to form supports as composite supports.
  • steel profiles are poured into concrete so that a common supporting effect of concrete and steel is created.
  • These are heavy steel construction with welded profiles, which cause relatively high material costs.
  • Another disadvantage is that the composite construction compared to the precast construction requires significantly longer construction times and thus generates a further cost disadvantage.
  • reinforced reinforced concrete columns can be created.
  • the reinforcement of reinforced concrete columns with high-strength steel is particularly advantageous for heavily loaded columns with predominantly normal force load - the steel is fully utilized in its carrying capacity.
  • the resulting reduction of the cross-section has a positive effect: the planning of slender columns makes the usable area larger and thus provides an economic benefit.
  • precast columns - these prefabricated in the factory components are characterized by a high dimensional accuracy.
  • the transfer of the finished parts is done with the crane. Time-consuming set-up times for the conversion of formwork elements or long-term reinforcement work and concreting on site can be omitted.
  • a disadvantage of the construction methods mentioned is that blunt shocks of the finished parts can be realized so far only at low loaded columns.
  • the reinforcement of the columns must be connected to that of the columns of the previous floor or of the underlying component: in situ concrete, this can also be done by overlapping lengths after standardization, otherwise suitable reinforcement connection means are used. Commonly used are threaded sleeves or clamped connections.
  • the disadvantage is the high expenditure of time that arises from the fact that every single connection of two reinforcing bars must be carried out manually; the prefabrication of reinforcement baskets is only possible to a limited extent.
  • the reinforcement sleeves require a certain amount of space, since the circumference of the sleeve significantly exceeds that of the reinforcing rod. This fact alone limits the number of installable reinforcing bars in cross-section, because a sufficient embedment in the cement matrix is a prerequisite for the load-bearing behavior of the composite reinforced concrete.
  • the object of the invention is to provide a system which makes it possible within a short construction time to create heavy-duty reinforced concrete columns in high quality execution - and so to optimize the economy in the production and quality, especially of high-rise buildings.
  • the invention provides, preferably with high-strength steel reinforced precast columns blunt and only separated by a thin mortar bed separated from each other.
  • a prerequisite for the force transfer in the butt joint is that the reinforcing bars made of steel - conventional reinforcing steel S500 or high-strength steel - are geometrically in one axis. This is inventively ensured by the fact that in the factory-made precast concrete fitting dowels are installed, which serve the adjustment and alignment of the connection.
  • FIG. 1 is a vertical section through the joint area shown, as an example, the reinforcement 5, 8 is shown simplified. This must be inserted according to the requirements of the action according to the design.
  • the supports of the lower floor 1 are provided and the reinforced concrete ceiling 3 is concreted on the upper edge of the finished parts 2.
  • the reinforcing bars 5 protrude about 20 to 40 mm out.
  • the precast columns 7 of the next floor are placed and aligned by means of the adjusting elements 6, 10.
  • the reinforcement 8 of the prefabricated reinforced concrete elements 7 protrudes at its lower edge 9 approximately 10 to 25 mm, the distance between the precast lower edge 9 and upper edge 4 of the Ortbetondecke 3 is about 50 mm or more.
  • the space between the support lower edge 9 and Ortbetonoberkante 4 is poured together with the joint between the reinforcing bars 5, 8 non-positively with low-shrinkage grout 11.
  • the lower edge 9 of the pillar finished part 7 is inclined - this is particularly advantageous in terms of the complete filling of the mortar joint with grout 11th
  • FIG. 2 is the stump stump invention to see in a plan view.
  • the reinforcing bars 5, 8 and the Justierdollen 6, 10 in plan view.
  • FIG. 3 shows the alternative embodiment of the precast support 7 with built-in base plate 12, which is preferably made in steel. Their arrangement creates a multi-axial bearing effect on the column foot and summarizes the transverse tensile stresses occurring there.
  • This is a particularly robust construction of the stump stump joint according to the invention.
  • the reinforcement of the lower support 1 projects about 40 to 55 mm beyond the upper edge 4 of the concrete ceiling 3.
  • the Justiertosstoff 6, 10 provide an exact location of the reinforcing bars 5, 8 in their axial extension.
  • the mortar joint is also pressed with potting mortar 11. Since this exemplary embodiment of the invention proves to be much more robust, here is a distance between the upper end of the bar steel 5 and lower edge of the Steel plate 12 of up to a quarter (1/4 d s ) of the diameter of the single rod possible.
  • reinforcements at the bar end 8 serve to improve the robustness of the column connection.
  • embodiments with steel ring inserts around the ends of the reinforcing rods 8 are also advantageous.
