Definitions

  • the present invention relates to a staircase with steps whose opposite ends are supported by supporting members of which at least one is a concrete stringer which extends along the staircase and to which the steps are connected by means of pins attached thereto and extending into matching holes in the stringer.
  • the staircase blank consisting of stringers, treads and risers is positioned in a form which must be adapted to the length of the staircase, which means that a large number of form elements must be available.
  • the cavity on the rear side of the staircase which is defined by the stringers, treads and risers, is filled with concrete.
  • the staircase is fettled, i.e. undesired concrete formations are cut away by means of a hammer and chisel and grinding is effected in the places where this is necessary.
  • the manufacture of staircases is rather complicated and above all tiring and dangerous to health owing to the cutting and grinding operations.
  • Fig. 1 is a perspective view of the construction of a staircase according to the invention.
  • Figs 2a and 2b illustrate two different types of treads which are useful in the staircase according to the invention.
  • Fig. 3 is a cross-sectional view of the tread accord ⁇ ing to Fig. 2A.
  • Fig. 4 illustrates the outside and inside of the treads.
  • Fig. 5 shows in more detail the attachment of the treads to a stringer.
  • Fig. 6 illustrates a form for the manufacture of a stringer
  • Fig. 7 is a corresponding view of a form for manufacturing treads.
  • a staircase according to the in ⁇ vention may consist of two stringers 10, 11 which are reflected images of each other, and treads 12 extending between the stringers and connected thereto by means of pins 15, 16 projecting from the ends of the treads, as illustrated in Fig. 2a, said pins extending into matching holes 13, 14 in the stringers.
  • the staircase according to the invention may however also be curved, in which case treads 12' of the type shown in Fig. 2b are used.
  • the staircase has but one curved stringer which is not shown in the drawings but which has the same holes 13, 14 as the stringers in Fig. 1 for receiving pins 15, 16 projecting from one end of the tread 12'.
  • the treads 12' are supported at their other end in a per se known manner by a vertical post or rod 38 extending through an opening 37 which is formed in the end portion of the treads and surrounded by a spacing collar 36.
  • the stringers 10, 11 are made of concrete and are of conven ⁇ tional shape and formed with conventionally designed end portions, but the shape may of course be modified to satisfy specific requirements.
  • the treads 12 12' are provided with pins 15 of a predetermined length, o one pin 15 and one longer pin 16 in each end surface, or i one end surface of the treads 12'.
  • the holes 13, 14 of the stringers are of different types, viz. on the one hand through holes and, on the other hand, nonthrough holes, i.e. formed with a bottom.
  • Figs 1 and 4 there are arranged for every second tread one through hole and one nonthrough hole 14 and 13, respectively, for receiving one long pin 16 and one short pin 15, while for the treads positioned therebetween merely nonthrough holes 13 are arranged for pins 15.
  • the pins 15, 16 can of course be cas a distance into the tread from the end thereof, but prefer ably consist of the end portions of rods extending along the entire tread and thus also forming reinforcements for the treads.
  • the pins 15 of the tread 12' illustrated in Fig. 2b can be formed of the ends of a rod which is bent like a hairpin.
  • the treads are of the cross- sectional shape illustrated in Fig. 3, i.e. they comprise two longitudinal ridges 17, 18 on the lower side which surround the pin-forming rods.
  • the ridge 17 extending alon the long side of the tread 12, which after mounting of the treads between the stringers faces forwards, is higher tha the other ridge 18, as is evident from Fig. 3.
  • the treads 12, 12' are made of concrete, as will be described in detail below. Attachments for e.g. anti-skid devices 19 ma be arranged on the upper side of the treads, or anti-skid devices may be cast into this upper side which may also have some sort of cover, for example of wood, plastic or cork. The forwardly facing long side may also have some sort of aesthetically attractive cover, if desired.
  • the lower side of the treads may have a layer of a sound- absorbing material, and in the space between the two ridges 17, 18, light fittings can be mounted to illuminate the staircase which according to the drawings lacks the usual risers.
  • the pins 15 of the treads are simply inserted into the matching holes 13 in the stringers, and at the ' same time care should be taken that every second tread has a longer pin 16, such that a pin portion 16' protrudes from the outside of the stringers 10, 11 to receive a clamping means.
  • the projecting pin portion 16' is suitably threaded, as illustrated at 16", to receive a clamping means in the form of a nut 21.
  • the pins 15, 16 may fit accurately into the holes 13, 14 in the stringers, but preferably the diameter of the holes 13, 14 is greater than that of the pins, thereby making it poss ⁇ ible to provide the pins with a sound-absorbing sleeve 23, before being inserted in the holes.
  • a sound-absorbing cover is thus formed round the portion of the pins which extends through the stringers, as shown in Fig. 5.
  • both ends of the sleeve 23 are open, whereas the sleeve for a nonthrough pin has a bottom, as illustrat ⁇ ed at the bottom of Fig. 5.
  • the treads 12 can be arranged to have their end surfaces engaging the stringers, but preferably a spacer 22 is arranged adjacent the tread, such that the tread end surface will be slightly spaced from the stringer, thereby facilitating the cleaning of the stair ⁇ case.
  • the longer pins 16 can be further slightly extended, such that e.g.
  • a staircase according to the invention can be mounted very quickly and easily - after applying the pins 15, 16 in the matching holes, merely the nuts 21 need by tightened, whereupon a rigid unit is obtained which is easy to handle. If desired, a number of treads can of course be provided with extended pins.
  • the staircase is curved, it is convenient first to arrange the treads 12' on the supporting post, where ⁇ upon the curved stringer is pressed onto the projecting pins 15, 16 of the treads.
  • a number of punched templates 29 are movable on the long side elements 39, 40 of the form and attachable in the desired position by means of screws 30.
  • the punched templates 29 are fitted with form pins 31 extending into the form cavity, of which some extend down to the bottom in order to produce the through holes 14, whereas others terminate at a distance from the bottom, thereby producing the nonthrough holes in the stringer.
  • the form illustrated in Fig. 6 is intended for the manufacture of the stringer 10 in Fig. 1, and to make the stringer 11 a mirror-invert- ed form is of course used.
  • the carriage 27 When making a stringer, first the carriage 27 is adjusted as stated above, thereby obtaining a stringer of the desired length, whereupon the punched templates are arranged in the intended positions, such that the holes formed by the form pins of the punched templates will be correctly spaced from each other. Sub ⁇ sequently concrete is poured and, if required, vibrated. After curing the concrete, the punched templates 29 are removed and possibly the carriage 27 is loosened, and any form pins extending through the holes 32 are removed, whereupon the finished stringer is removed from the form.
  • the treads 12 are preferably cast in pairs in upright forms 42, each having two form halves 33, 34 which define the form cavity.
  • the form cavity comprises a bottom through which the rod ends forming the pins 15, 16 may extend, and is upwardly open.
  • clamps 35 which have a through opening for supporting the upwardly facing end portions of said rods.
  • a number of forms 42 are arranged on a conveyor belt which is vibratable, such that after joining the form halves and arranging the pin-forming rods and pressing on the clamps 35, the rod ends extending therethrough, concrete can be filled into the form cavities from above, and then the forms 42 are moved on the conveyor belt during vibration and, optionally, additional filling of concrete.
  • staircases As is evident, it is possible to readily manufacture a staircase according to the invention, whose construction is highly advantageous and whose weight is considerably lower than that of staircases which are factory-made in a conventional manner.
  • the stringers as well as the treads can easily be provided with decorative items and, if required, a banister may easily be attached.

Abstract

L'invention décrit un escalier préfabriqué, possédant deux traverses (10, 11) ou, de façon alternative, une traverse (10, 11) et un pilier de support. Entre les traverses (10, 11), ou entre la traverse et le pilier de support, s'étendent des marches (12) fixées à la traverse (10, 11) au moyen de chevilles formant une saillie à partir des extrémités des marches et, de préférence, constituées par les extrémités opposées de tiges traversant la totalité de la marche. Les chevilles s'étendent soit complètement à travers les traverses, afin de recevoir, sur une partie en saillie située à l'extérieur desdites traverses, des moyens de serrage servant à assembler solidement l'escalier, soit partiellement seulement à travers lesdites traverses. A l'intérieur des trous (13, 14) percés dans les traverses et conçus pour recevoir les chevilles, celles-ci sont entourées par un matériau d'amortissement. L'invention décrit également un moule servant à fabriquer les traverses (10, 11) et les marches (12). Le moule de traverse comprend un élément d'extrémité réglable, ce qui permet de fabriquer des traverses de différentes dimensions, ainsi que des gabarits perforés réglables équipés de chevilles de moule, ce qui permet de réaliser les trous servant à recevoir les chevilles des marches en fonction des positions souhaitées. Le moule de marche comprend deux parties réunies au moyen d'éléments de serrage constituant également des supports pour les chevilles (15, 16) des marches.
