Definitions

  • the invention relates to a prestressed concrete structure having a hollowed out slab behavior, in particular for constituting a bridge deck, a covering or a floor.
  • a hollowed-out concrete slab obtained by molding is known. This technique practically requires that the slab has reduced dimensions. It has been proposed to increase these dimensions by constituting the slab by means of two concrete plates braced by a steel trellis (CH-A-401 120), but such a slab has the disadvantages and difficulties of producing a mixed structure. steel-concrete.
  • the object of the present invention is to provide a concrete structure having a hollow slab behavior without having the above-mentioned drawbacks and limitations.
  • the structure of the invention which comprises two reinforced or pre-stressed concrete plates arranged opposite and connected by a multidirectional lattice disposed in the volume between the plates, is characterized in particular in that said lattice consists of elements rigid prefabricated reinforced or prestressed concrete, each comprising at least one group of at least two bars and at least one cross member arranged along the three sides of a triangle, and in that the structure comprises concrete blocks located between the two plates and integral with at least one of the plates, and cables for prestressing the structure anchored at their ends in some of the massifs and passing inside said volume and / or in the vicinity of the plates while remaining at the exterior of the lattice concrete.
  • the invention also relates to a method for producing such a structure from these trellis elements.
  • At least one plate is prefabricated having reserves suitable for each receiving a meeting point of two bars of a trellis element, there are prefabricated trellis elements on the plate so that the chosen meeting points are placed in the reserves, concrete is poured into the reserves around said points to form nodes and secure the plate and the lattice elements in a rigid transportable unit.
  • some of the cross members of the trellis elements are used to produce the difficult part of the formwork of the other plate of the structure, the rest of the formwork being achievable by means of formwork simply slid between the elements of trellis parallel to the length of the structure.
  • some of the crosspieces of the trellis elements follow each other by forming a line which extends over part or the entire length of a plate which possibly includes places where two crosspieces are joined and which possibly meet with other lines.
  • the bridge shown diagrammatically in FIG. 1 comprises, in a manner known per se, an apron made up of successive spans 1 and resting on abutments end 2, 3 as well as on intermediate stacks 4.
  • the invention relates, firstly, to the structure of the bridge deck and, by way of example, a common span of the deck will be described below.
  • This span comprises at each end a massif.
  • the span deck consists of two plates or “tables in reinforced or prestressed concrete, respectively lower and upper, connected by a concrete triangulation.
  • the assembly is prestressed by cables which run from one block to another passing through the volume of the triangulation but outside the concrete of the triangulation, and under the concrete of the lower table thanks to the passages provided. for this purpose.
  • Figure 2 is a longitudinal section through the span in the region of the front end of the span.
  • the front massif 5 of the span located between the two tables 6, 7 and forming a body with them.
  • the cable 8, at its exit from the block passes through the volume of the triangulation then in a passage 10 formed in the lower table 6; it then undergoes a deviation and then goes straight along table 6; further on, it will be deflected in the opposite direction, will go up in the volume occupied by the triangulation then will lead to the solid mass located at the other end of the span.
  • Figure 3 is a longitudinal section of the deck at a place where the cable 9, in turn, passes through a passage 11 of the lower table, then spins straight along the table.
  • Figure 4 is a longitudinal section of the deck at another location where the two cables 8, 9 go up in the volume of the triangulation.
  • Figure 5 is a longitudinal section of the other end (or rear end) of the span which shows the other block 12 located between the tables and integral with them.
  • Anchoring blocks are normally provided on the end abutments of the bridge.
  • Figure 6 shows for example an anchor block 5 on the abutment 3 of the front end of the bridge.
  • At least some of the anchor or passageways for the prestressing cables are preferably essentially made up of veils or concrete slabs, as best appears in FIG. 7 which is a half - transverse section of a massif such as 12.
  • the massif is made up of several sections which each include a vertical veil or central plate 14 and oblique veils or lateral plates 15,16, the three veils or plates being arranged in leg goose.
  • FIG. 8 which is a longitudinal section of the massif, it can be seen that the central veil 14 has a markedly greater extent than the lateral veils.
  • the prestressing cables pass or are anchored in the central web 14.
  • the cable passage plane is designated at 17 in FIG. 7.
  • the solid masses on the abutment have a similar structure.
  • the invention also relates to a particular embodiment of triangulation.
  • the triangulation is preferably a structure consisting of concrete bars which may have a small cross section because the prestressing cables pass outside the concrete of the bars.
  • the bars meet the tables in places or "nodes whose shapes are designed to deflect the prestressing cables, as necessary.
  • Figure 9 which is a current cross section of the deck (or in other words, a section along the length of a segment) shows the bars 18 of the triangulation which lead to nodes 19, 20, respectively in the lower table 6 and in the upper table 7. Some of the nodes have grooves 21 through which the prestressing cables can pass, such as cables 8 and 9.
  • the tables include, as necessary, ribs which have passages cooperating with the grooves of the nodes to guide and deflect the prestressing cables, either along the table or through the table.
  • FIGS. 10 and 11 are longitudinal vertical sections of the lower table at two successive locations and in FIG. 12 which shows transverse vertical sections made in these locations.
  • FIG. 10 and 11 we have disregarded the triangulation bars.
  • Figures 13 and 14 respectively show a node of the lower table seen from above, and a node of the upper table seen from below.
  • Figure 15 a schematic perspective of a portion of the deck.
  • the arrow 23 designates in the figure the direction in which the bridge extends. We find on this figure some of the characteristics which were described previously as well as other charac which will be mentioned below.
  • the structure also includes prestressing cables 8 ', 9', which extend transversely (while the cables such as 8 and 9 extend longitudinally) and which are anchored in solid masses or concrete sails, such as for example the veil 24 situated between the tables 6, 7 and being integral with them.
  • prestressing cables 8 ', 9' which extend transversely (while the cables such as 8 and 9 extend longitudinally) and which are anchored in solid masses or concrete sails, such as for example the veil 24 situated between the tables 6, 7 and being integral with them.
  • These transverse cables like the longitudinal cables, pass outside the concrete of the bars 18 of the triangulation and are deflected at the locations of some of the nodes of the lower table.
  • the prestressing cables can pass in the vicinity of the upper table instead of passing in the vicinity of the lower table.
  • the cables when they pass under the lower table or above the upper table, do not deviate from it more than a distance equal to a fraction of the distance of the two tables, for example a distance equal to one tenth of the distance between the tables.
  • the cables are mainly located between the tables.
  • the invention also relates, as has already been indicated, to a technique for constructing the bridge deck.
  • the basic element is generally a rigid trellis element which, in a typical example, consists of two bars 18 and a cross-member 25 arranged along the three sides of a triangle as seen in FIG. 16.
  • FIG. 17 schematically illustrates the production of a trellis pyramid by means of trellis elements as described above.
  • the pyramid is made up of four elements A, B, C, D which are arranged so that each lattice element provides a bar arranged along one of the edges of the pyramid.
  • the four elements A, B, C, D are arranged in pairs in two oblique planes, the meeting points of the bars of the elements being brought together to form the top of the pyramid, the two elements of a couple having their two aligned crosspieces 25 and two bars 18 juxtaposed, the other two bars 18 being arranged along two edges of the pyramid.
  • the top of the pyramid is housed in a reserve 26 of a plate and concrete is poured around the reserve to form a knot around this summit and block the pyramid in position.
  • the trellis elements are held by any suitable means. If necessary, the two pairs are and remain temporarily braced until complete stiffening.
  • pyramidal configuration can be obtained with other trellis elements and that this shape, while being preferred, is not limiting.
  • pyramids P appear in FIG. 15 except in the foreground which passes through the median plane of a file of pyramids and which consequently shows only two elements of each pyramid.
  • crosspieces do not intervene in the function of the trellis, their role is to maintain the bars in the desired arrangement during the completion of the work and to serve as formwork for formworking the parts of the upper plate which, usually, are difficult to form.
  • the prestressing cables are possibly protected, for example by a concrete coating which cannot be confused with the concrete of the triangulation.
  • the invention makes it possible to achieve significant savings in concrete, up to 30%, in the construction of a bridge.
  • the efficiency defined by the ratio between the height of the vertical range through which the pressure line must pass (due to the prestressing, the weight of the structure and the operating loads) and the total height of the structure (that is to say the height of the hollowed slab) can reach 0.65 to 0.95 according to the teachings of the invention, instead of remaining in the range 0.35-0, 55 obtained by conventional methods.
