Definitions

  • a building structure particularly a road bridge struc ⁇ ture, and a method of making such a building structure.
  • the invention relates to a building structure of the kind set forth in the introductory part of claim 1.
  • a particularly important field of use of such a building struture is for road bridges, and the invention will in the following be described with particular reference to that field of use, but it will be realized that the invention may likewise be used for other building struc ⁇ tures where similar problems exist.
  • a road bridge structure covering a span of a bridge typically comprises a lower part consisting of a sup ⁇ porting beam of reinforced concrete and an upper part comprising e.g. a base layer of concrete and a top layer of asphalt.
  • the membrane consists of a strongly adhesive layer of material, e.g. consisting of blocks of bitumen-butadiene-styrol-butadiene embedded in a matrix of bitumen, and the force transfer means con ⁇ sist of bolts or iron rods embedded in the concrete of the lower part and extending into the layers of the upper part.
  • a strongly adhesive layer on a bituminous basis has the disadvantage that the layer will unavoid ⁇ ably be subjected to a certain amount of shearing forces in some situations of load and/or temperature variations, whereby after a period of ageing small cracks may be formed impairing the liquid-impermeability of the layer.
  • the layer cannot be expected in the long run to maintain a perfect liquid proof seal against the bolts or iron rods piercing the layer.
  • a further disadvantage is that the upper surface of the beam must be thoroughly cleaned, degreased and dried up before the adhesive layer can be applied.
  • the adhesive membrane has to be chipped off together with the upper layers, to which it adheres, thus expos ⁇ ing the surface of the beam to wheather conditions during the period of repair or renovation.
  • a membrane as therein defined will not be subjected to substantial tearing or shearing forces in its own plane, but practically only to compressional forces perpen ⁇ dicular to its plane.
  • Synthetic thermoplastic sheet or cloth materials having the properties of non-adhesiveness and low friction are available in the trade. Particular reference is made to that marketed by Du Pont under the registered trademark Hypalon ® . This material is impervious to water and oils and has a high resistance to a wide range of chemicals, including acids and dissociated salts. Moreover, it is unaffected by both high and low temperatures and has a very long lifetime. It can easily be pressed into the shape of hoods with collars, and the latter can be heat- sealed to the plane sheet laid out on top of the lower part.
  • the non-adhesion and low friction of the membrane to- wards the upper part can be further secured by means of a lubricant.
  • the membrane incl. the hoods can be left in position to protect the beam against the intrusion of rain water or other liquids during the period of repair of renovation.
  • the invention also relates to a method of making a building structure of the kind referred to.
  • the method is characterized by the steps set forth in claim 3.
  • the correct positioning of the block-like elements relative to the lower part is greatly facili- tated, because no great accuracy is required in perform ⁇ ing the steps.
  • Figs. 1-5 are vertical longitudinal sections through a bridge structure in various stages of its production and
  • Fig. 6 is a vertical cross section through the bridge structure.
  • Fig. 1 is the bottom of a shuttering in which a reinforced concrete beam is to be moulded.
  • 2 is the principal reinforcement, 3 iron bars supporting a soft iron distributory reinforcement 4 adjacent to the con ⁇ templated upper surface of the beam.
  • An anchor 5 having a threaded bore is welded (at 6) to the reinforcement 4. The bore is closed by a plastic cap 7 to prevent the penetration of concrete during moulding.
  • Fig. 2 the beam 8 has been moulded and cured, and the shuttering 1 has been removed. Lengths of membrane cloth have been rolled out, and holes 10 have been cut in the cloths above the anchors 5 so that the cloth can now lie smoothly on top of the beam. The lengths of cloth are heat-sealed together along their edges to form a continuous sheet in the whole width of the beam.
  • Fig. 3 the caps 7 have been removed, and concrete blocks 11 have been fastened to the anchors by means of steel screws 15.
  • the blocks 11 may alternatively consist of any other suitable material having the required mechanical strength and may e.g. be of a circular, oval or rectangular configuration in horizontal plane.
  • Hoods 16 of the membrane material have been placed on and around the blocks 11, and their collars 17 have been sealed to the cloth 9 by hot airblast and pressure.
  • mats 18 of a draining hygrophilic material are placed on top of the membrane 9, and a layer of draining concrete 23 is moulded, whereby recesses are formed which fit around the hood- clad blocks 11.
  • a reinforcement ring 19 connected by stays 21 to an upper ring 20 may first be placed around each block 11, and a body of expanding mortar 22 may be moulded to ensure a particu ⁇ larly firm and permanent grip around the blocks 11.
  • a top layer 24 of asphalt is laid out in adhesive engagement with the concrete layer 23.
  • Fig. 6 illustrates a manner of efficiently draining off water from the hygrophilic layer 18 to a gutter 26.

Abstract

La structure de construction, telle qu'un pont routier, comporte une partie inférieure, par exemple une poutre (2, 3, 4, 8) en béton armé, ainsi qu'une partie supérieure (23, 4) séparées l'une de l'autre au moyen d'une membrane (9) imperméable aux liquides composée d'une matière en feuille non adhésive, à faible frottement, et formée avec des parties de cloche (16) renfermant de manière étanche des éléments (11) en forme de bloc, saillant vers le haut à partir de la surface supérieure de la partie inférieure (2, 3, 4, 8). Les éléments de cloche-revêtement (11, 16) s'adaptent à nouveau de manière étanche dans des évidements formés dans la partie supérieure (23, 24). Les forces horizontales sont transférées de la partie supérieure à la partie inférieure par l'intermédiaire des côtés des éléments (11) en forme de bloc, de cette manière perpendiculairement à la matière de la membrane. Selon un procédé pratique de construction de la structure, on fixe premièrement les éléments (11) en forme de bloc à la partie inférieure située au-dessus d'une feuille entière de matière de membrane, puis on applique des parties (16) de cloches préformées de la même matière de membrane aux éléments (11) en forme de bloc, puis on les scelle à ladite feuille (9).
