Definitions

  • Designation formwork module for the production of concrete-saving walls in particular
  • the present invention relates to a formwork module for producing in particular concrete-saving walls with a first and a second formwork wall, and to a wall produced by means of this formwork module.
  • Cost-driving factors in house construction are in particular the large quantities of building materials used, and here in particular of concrete. If it is necessary or intended, in particular thick walls, for example those with a width of 24 or 30 cm, to be made from concrete with regard to the static requirements, then correspondingly large amounts of concrete must be used. This increases the manufacturing costs of such walls considerably.
  • a formwork module for producing, in particular, concrete-saving walls with a first formwork wall which has at least two sections derived from the shape of a trapezoid, the further, correspondingly designed second section proceeding continuously from at least one end of the first section is arranged, and with a second formwork wall, which is designed substantially corresponding to the first formwork wall, and wherein the formwork walls are arranged spaced apart from one another such that the base lines of the sections are arranged parallel to one another.
  • Sections derived from the shape of a trapezoid in the sense of the present invention are typically those sections which have a base line and, starting from this, two side lines, so that a trapezoid is formed with an imaginary second base line arranged opposite the base line.
  • the second baseline is not part of the sections.
  • the two side lines form an obtuse angle ⁇ with the base line, preferably in a range from 120 ° to 150 °, preferably the Angle ⁇ between the baseline and one side line and the baseline and the other side line is identical. That is, in the case of an imaginary complete trapezoid, which is formed by adding the imaginary further baseline, the baseline belonging to the section is shorter than the merely imaginary baseline lying opposite it.
  • the sections can also be designed in such a way that, starting from a base line, a side line is arranged at an obtuse angle ⁇ , which correspondingly merges again into a base line.
  • These sections can also be described as trapezoidal sections, which are halved at the level of the center of the base line and which are assembled to one another after rotation of a section by 180 ° and reflection of the other section.
  • Sections can be used for the formation of corners which, starting from a base line, have a side line forming an obtuse angle ⁇ therewith, and this section is connected to a correspondingly designed and mirror-inverted second section.
  • the two formwork walls are spaced from each other in such a way that a kind of zigzag-like band is formed by them, but interrupted in each case by linear areas formed by the respective baselines.
  • These linear areas formed by the base lines serve as a support surface for preferably provided support means on both sides of the formwork system formed by the formwork walls 1 and 2.
  • the support means for holding and fixing the two formwork walls to one another can in particular be formed from plates and / or pipes or rods and / or frame systems, as are known from formwork modules used in construction, the support means preferably being firmly connected to the formwork walls ,
  • the formwork module according to the invention typically consists of units, formed by the two formwork walls and the support means firmly connected to them, in particular held to one another by at least one, preferably at least two, more preferably exactly two anchors.
  • the formwork module according to the invention advantageously makes it possible to produce statically stable walls with a considerably reduced amount of concrete. This is how for example, in the manufacture of a wall with a width of 24 cm with a formwork module for a wall with a width of 24 cm, only a quantity of about 0.085 m 3 of concrete / m 2 of wall is required. At least an amount of about 0.06 m 3 is preferred, a range from 0.065 m 3 to 0.095 m 3 concrete / m 2 is more preferred.
  • the formwork module according to the invention thus offers a large number of possible combinations and thus of possible uses. It is also easily possible to produce stable wall corner elements with the formwork module according to the invention. If, for example, the provision of a right angle in a wall corner element is desired, the sections tapering towards the corner from both sides can be of identical design and can be connected to one another.
  • At least one reinforcement element is advantageously arranged between the formwork walls.
  • This reinforcement element is preferably provided centrally between the two formwork walls.
  • a bendable mat is particularly preferably provided as the reinforcement element, but other curved reinforcement elements can also be used.
  • the reinforcement elements are held in position by structural iron in particular.
  • the support means arranged on the two outer sides of the formwork walls formed by the respective base lines of the sections are connected to the formwork walls by at least one anchor, preferably at least two anchors, the anchor being arranged approximately at the center of the base line.
  • An anchor arranged in this way firmly connects the support means arranged on the two outer sides to the two formwork walls. It is removed after the concrete has been poured in and hardened.
  • the sections are advantageously formed from a plurality of components which can be connected to one another, in particular screwed, and also hooked.
  • planar middle elements extending the side and / or base lines of the imaginary trapezoid can be arranged between these components. This makes it possible, for example, to easily convert a 24 cm thick wall into a 30 cm thick wall to manufacture the same components.
  • the flat central elements have elongated recesses / bores through which a projection, for example arranged on the section, can engage in a sliding manner. Then there is the possibility of widening the wall, such a flat central element advantageously having two elongate recesses or one arranged in the same way
  • Such a flat middle element can be provided with at least two such elongate recesses, in which the projections of the sections engage, arranged on the two sides of the flat middle element facing the sections, in order to achieve a safe and precise construction of the formwork walls.
  • any other type of connection of the central elements to the sections can also be provided.
  • the recesses / bores can be round or square, for example.
  • a secure connection between the sections and the central elements is achieved by means of a screw connection, in which case the projection which engages in the elongated hole, for example, is advantageously provided with a thread, so that after use of the central element, it can be firmly connected to the section by a nut.
  • At least one projection is provided in the central elements for the recesses / bores in the sections and vice versa.
  • a secure connection cannot only be formed by a system of recess / projection, any other conceivable connection system is also possible, for example a connection via interlocking projecting hooks, anchors, provided detents, etc.
  • the formwork wall can also be formed in one piece.
  • the formwork wall and thus also the sections or the planar central elements are preferably made of aluminum and / or galvanized sheet metal, for cost reasons preferably made of galvanized sheet metal.
  • the present invention further relates to a wall made with the formwork module according to the invention.
  • This wall meets the requirements placed on these in house construction and is also considerably less expensive to produce in view of the very small amount of concrete used in comparison to conventional solid concrete walls.
