Definitions

  • the present invention relates generally to the field of construction and, more particularly, to the structures of edges of faced stair steps.
  • said facing structure for a stair step forward portion is described in DE Patent No. 3,907,959; Int. Cl. E04F 11/16, issued 1990.
  • said facing structure comprises a ⁇ -shaped working member and a vertical anchor portion connected to a lower surface of the said working member.
  • both the working member and anchor portion are made of a resilient material.
  • said facing structure comprises a ⁇ -shaped working member, a horizontal and a vertical fastening members all made of a resilient material, said fastening members are interconnected and attached to the working member of the facing structure through an additional connecting member.
  • a disadvantage of the known facing structure for the stair step forward portion resides in the fact that it has a complicated cross-section shape necessitating the use of complex attachments when fabricating thereof. Moreover, it is necessary that horizontal facing plates of stair steps be provided with a special platform to accommodate the working member of the said facing structure for the stair step forward portion, in other words, a strictly defined thickness, which complicates the assembly of the facing structure and increases the cost of works performed.
  • Another disadvantage of the known facing structure for the stair step forward portion consists in that due to a small thickness of the working member, it is essentially impossible to ensure both a long operation life of the facing structure and conditions of spontaneous decomposition of the ice coating formed on the surface thereof under the action of a pedestrian weight.
  • a facing structure for a stair step forward portion comprising a working member made of a resilient material and a horizontal and a vertical fastening member, wherein the working member is manufactured in the form of a beam with its rearward and lower surfaces being connected to said horizontal and vertical fastening members respectively, the thickness H of the working member and the modulus of elasticity E of a resilient material satisfy the relationships:
  • h 1 the thickness of the horizontal fastening member [m]
  • k the coefficient equal to 10 11 [n/m 3 ].
  • fastening members be made of the material of the working member and located, for example, integral therewith.
  • the fastening members be made of the material whose modulus of elasticity is at least by an order of magnitude greater then the modulus of elasticity of a resilient material of the working member.
  • Such an accomplishment of the facing structure of the stair step forward portion enables simplification of the process of its manufacture, since connecting members are absent and fastening members are connected not to each other but to a rather massive working member of the facing structure.
  • the use of the facing structure of the stair step forward portion in accordance with the present invention makes it possible to simplify the process of its assembly, since it is unnecessary to provide the facing material of stair step surfaces with special platforms.
  • conventional plates of rectangular shape having the same thickness may be used without any special additional working-up of their forward portions.
  • a further result attained when using the facing structure in accordance with the present invention consists in that by satisfying the above relationships (1) and (2), the edges of the stair steps acquire springiness. As a consequence, stresses arise on the “working member-ice coating” interface whose amount meets the conditions of the “effect of self-cleaning” of the edges of outdoor stair steps from the ice (ice coating) under the action of a pedestrian weight.
  • FIG. 1 is a general cross-sectional view of faced stair steps, in accordance with the present invention.
  • FIG. 2 is a side view of an embodiment of fastening members of a facing structure of a stair step forward portion, said members being made of a resilient material and integral with a working member, in accordance with the present invention
  • FIG. 3 is a side view of an embodiment of metal fastening members of a facing structure of a stair step forward portion, in accordance with the present invention.
  • a facing structure for a forward portion of steps of the stair 1 comprises a working member 2 made in the form of a beam, a vertical fastening member 3 and a horizontal fastening member 4 , with lower 5 and rearward 6 surfaces of the said working member 2 being connected to said vertical 3 and horizontal 4 fastening members respectively.
  • an upper surface of the working member 2 is provided with teeth 7 .
  • the horizontal fastening member 4 is located under a facing material 8 of the surface of a respective step of the stair 1 .
  • the vertical fastening member 3 is located under a facing material 9 of the surface of a respective riser of the stair 1 . Ceramic, marble and the like plates may be used as the facing material 8 and 9 . Attachment of the facing structure of the stair step forward portion to a concrete stair 1 and of the facing material 8 and 9 is accomplished by means of an adhesive 10 . In the preferred embodiment of the present invention, a cold-resistant “Atlas Plus” brand adhesive is used.
  • the fastening members 3 and 4 may be made of the same material as that of the working member 2 , and in particular integral therewith. However in some cases, it is advisable that the fastening members 3 and 4 be made of more rigid material (FIG. 3), for example aluminium alloy.
  • the thickness H and the modulus of elasticity E of the material of the working member 2 must satisfy the relationships (1) and (2).
  • fastening members 3 and 4 are made of more rigid material (whose modulus of elasticity is at least by an order of magnitude greater then the modulus of elasticity of a resilient material of the working member 2 ), they may have different section, for example an angle ⁇ -shaped section (FIG. 3).
  • Assembly of the facing structure of the stair step forward portion is carried out in the following sequence.
  • the surface of the stair step and riser cleaned from dirt and dust is coated with the layer of an adhesive 10 .
  • the facing structure of the rearward stair step portion is mounted.
  • an upper surface of the horizontal fastening member 4 and a rearward surface 6 of the working member 2 are coated with the layer of an adhesive 10 followed by the installation of a plate 8 of the facing material of the horizontal step surfaces.
  • the facing of a riser using a facing material 9 is carried out in much the same way.
  • the thickness H of the working member 2 exceeds the sum of the thickness h of the facing material 8 and the thickness h 1 of the horizontal fastening member 4 , then, by varying the layer thickness of the adhesive 10 , a required location of the facing members, for example flush-mounted, is provided. Connection of the working member 2 and fastening members 3 and 4 of the facing structure of the stair step forward portion directly to the stair 1 imparts more reliability and longevity to the structure.
  • the ice or ice coating is formed on the surface of the working member 2 .
  • elastic strains of the working member 2 take place resulting in stresses on the “working member-ice” interface, the amount of said stresses being sufficient to decompose the ice coating. In this way “self-cleaning” of the most dangerous portion of the stair step from the ice occurs.
  • the facing of the stair step forward portion may be used when manufacturing outdoor stairs and that for pedestrian underpasses thus ensuring simplification of the structure and assembly and realizing the “effect of self-cleaning” from the ice (ice coating) while it is in use.
