Definitions

  • the invention relates to a method for the construction of a staircase, in which at the construction site a stairway to be formed is measured as a top view of the staircase, which is delimited from the outside cheeks to the walls of the installation site surrounding the stairway and to a stairwell hm from the inside cheeks and in which the measured values found are used to construct the stairs.
  • the invention further relates to a device for measuring the bottom of a staircase at the place of construction of a staircase to be constructed, essentially consisting of a laser range finder emitting a laser beam.
  • Stairs that are designed and manufactured as one-off or custom-made products must be measured at their place of construction before starting the construction of the stairs.
  • the intended fixed or corner points of the so-called stair base are measured in known methods.
  • the bottom of the stairs is the graphic top view of a staircase on a scale of 1: 1.
  • the known points of the bottom of the stairs at the bottom of the installation location are measured on one level in the known method.
  • the start, the beginning of the staircase and the exit as the end of the staircase are marked at the construction site in the bottom of the staircase and the External cheeks facing the installation site are measured as projected basic lengths.
  • the inner cheeks facing away from the outer cheeks are also measured as projected basic lengths.
  • the inner cheeks limit the so-called stairway eye.
  • the angles between the adjacent outer cheeks and the angles between the entrance and the adjacent outer cheek and the outlet and the adjacent outer cheek are measured.
  • electronic protractors are also used here.
  • a disadvantage of this method is that imprecise angles of the wall dimensions of the installation site and inaccurate length dimensions of the installation site lead to the fact that when measuring the bottom of the stairs in one plane the stairs to be constructed do not run parallel to the wall or the stairs no longer fit dimensionally, so that it cannot be installed later due to poor fitting accuracy.
  • the invention is therefore based on the object of compensating for errors in the construction site and improving the dimensional accuracy or the accuracy of fit of the stairs to be constructed.
  • the lengths of the cheek sides of the triangles corresponding to the outer cheeks of the stairs are formed from two partial lengths which correspond to the horizontal distances of the corner points delimiting the cheek side from a vertical line lying connecting the corner points.
  • cheek sides are formed from partial lengths, which take into account the height construction of the corner points, takes into account inaccuracies in the walls of the construction site surrounding the stairs, for example by non-vertical wall guidance, which further improves the accuracy of fit of the stairs.
  • an approach to be arranged between outer cheeks and inner cheeks is formed with predeterminable starting corner points as the outer side of a triangle, the third corner point of which forms a vertex lying on the vertical axis.
  • An outlet to be arranged between outer cheeks and inner cheeks is formed with predeterminable outlet corner points as the outside of a triangle, the third corner point of which forms an apex lying on the vertical axis.
  • a distance specified as a target dimension is compared with a distance calculated as the actual dimension. By comparing the calculated actual dimension with the specified target dimension of the distance between the facing corner points of entry and exit, any measurement errors can be sufficiently recognized. If a predeterminable tolerance limit is exceeded, for example, a warning can be issued and the measuring process repeated.
  • the measured values are used as initial values for a software program for computer-assisted stair construction, which can be connected to a software program for computer-assisted stair manufacturing.
  • the fact that the measured values are used as initial values for a software program for computer-aided staircase production makes the construction of the staircase considerably easier and the accuracy of fit of the staircase can be increased.
  • the process between measuring, designing and manufacturing the staircase can be considerably simplified and thus also carried out more economically and in a shorter time.
  • the software for stair construction is integrated into a program for achieving the angles of the base of the staircase.
  • the software program for construction is avoided by separately determining the angles and by entering the calculated angles.
  • laser range finders to be held in the hand are used for the distance measurement. These laser range finders must be arranged horizontally in a horizontal plane to measure distances.
  • a disadvantage of the known devices for measuring the bottom of the staircase is that when measuring by the method according to the invention, in which the axis sides of the triangles leading to the vertical axis are measured perpendicular to the vertical axis, i.e. horizontally at the intended height of their corner point, the measurement from in the vertical direction vertices located above is difficult.
  • Another object of the present invention is therefore to provide a device in which horizontal distances from a vertical axis can be measured without problems even at corner points located above.
  • the laser range finder is coupled to a theodolite and forms a measuring unit which is arranged on a stand which can be arranged in the stairway eye, and in that the laser beam of the laser range finder is pivoted can be aligned around a vertical axis and by tilting in a vertical plane to the corner points of the triangles to be measured.
  • the measuring unit can be positioned on a tripod at any fixed height and, after aligning the laser beam, by pivoting and tilting it towards the Send corner point are aligned, the distance to the corner point to be measured is determined. With the aid of the distance and an angle of inclination measured with respect to a horizontal, the horizontal distance between the corner point and the vertical axis can be determined by a simple trigonometric function. This enables problem-free measurement of both corner points lying in the floor area and corner points lying in the ceiling area with a single height arrangement of the measuring unit.
