Definitions

  • the invention relates to a reinforced concrete component, which is mainly used in residential construction.
  • reinforced concrete components e.g. the reinforced concrete beams of sealing rib ceilings are known, which are formed by dry assembly of individual perforated bricks with each other, various sheet metal cuts or grooves in the pressure zone being filled with cement mortar or concrete. Their shape depends on the shape of the perforated brick used.
  • the steel-ceramic beam is a light space framework with a constant reinforcement cross-section of the top chord and with a cross-section of the bottom chord that varies depending on the span and type of ceiling.
  • the lower flange - the flange - is framed with the ceramic stone, the cross section of which corresponds approximately to an open ellipse, which is filled with concrete with the protruding reinforcement inserted into it.
  • the ceiling beam ITB-70 is also known from pages 357, 358 of this publication.
  • the finished flange of this reinforced concrete beam with the protruding reinforcement has a cross-section which is characterized by flat shear off of the corners, which round off its surface and which is adapted to the slag concrete perforated bricks currently used in Poland.
  • the known beams are designed for a specific type of construction.
  • the bars are only suitable for cooperation with a shape of the filler element in its support zone.
  • the essence of the invention is that the compartment of the reinforced concrete component with a rectangular cross-section is provided with at least one slat, preferably made of wood, which is stably attached to at least one of the surfaces in the course of its formation.
  • the equipment of U n-terflansches of the element with the additional slats which are attached to the side surfaces, enables any and easy adaptation of its form to the various elements which are used for filling in its support zone. These slats also allow easy installation of finishing elements, such as false ceilings.
  • the reinforced concrete component according to the invention can be manufactured and used both in the finished and in the monolithic version. It can be used in ceilings, ceiling roofs, rafters roofs and walls. In the case of walls, it can be used to form light posts with a double T or T profile cross section. The slats are then used for fastening, for example for wood veneering.
  • the reinforced concrete component 1 of FIG. 1, which forms a beam or a reinforced concrete post, has a rectangular cross section.
  • Two wooden slats 2 are stably fastened along its sides.
  • the reinforcement 4 protrudes from the element 1 and is concreted into the ceiling or wall after the element has been installed.
  • the element is shaped under test conditions on a hard, balanced bed with the slats 2 made of waste wood, which makes it very easy to shape it.
  • the element 1 of FIG. 2 is provided with a wooden slat 2 which is attached to the longer edge of its cross section.
  • element 1 has the function of reinforced concrete beams, its final shape, especially in the concrete part, depends on the shape of the elements filling the spaces between the beams.
  • Fig. 3 shows the cross section through the beam after it is concreted with a beam 5 or without a beam 6 with concrete.
  • the bar is ver with wooden slats 2 see whose cross-section is adapted to the shape of the perforated brick in its support zone.
  • the bar forms a ceiling component, which is shown in two variants in FIG. 4.
  • the beams 5 have no concrete slab.
  • the bars 6 are designed with such a plate.
  • the ceiling is provided with the plaster 8 from below, which is arranged in the vicinity of the element 1 on a net which is attached to the wooden slats 2 or is provided on the false ceiling 7.
  • the reinforced concrete component which forms a light post, is used for wall reinforcement.
  • a light wall which is designed in two variants, is shown in Fig. 5.
  • a partial prefabricated post is used here.
  • the wall with the backfill 11 has heat-insulating inserts 10.
  • the wall is provided with the wall paneling 7 from the inside and the plaster 8 from the outside.
  • the wall is provided with plaster 8 from the inside and with a ventilated front plate 12 from the outside.
  • the partition 13 is inserted into a construction toothing 14.
  • the element 1 is provided with two wooden slats 2 and in the second with a slat 2.
  • multifunctional filling elements 9 with the various resistance and thermal insulation properties were used.
  • the solution shown enables very economical construction, which does not require the use of heavy construction equipment and highly trained assembly workers.
  • the prefabrication of elements can be carried out by trained workers under polygon conditions.
