Definitions

  • the invention relates to the field of construction, namely to reinforced concrete floors of prefabricated girder-free frame buildings.
  • a reinforced concrete frame which is a girder-free, drip-free structure and contains above-column and inter-column slabs having loop outlets on the edges and grooves symmetrically located relative to each other, along which reinforcement is installed through the overlaps of the loop outlets of adjacent slabs, and passing through the holes in column slabs are prefabricated along the height of the column, in which longitudinal reinforcement is exposed in the places where the above column slabs are installed (AS USSR JM ° 1114749).
  • the disadvantage of this design is the low strength of the joints between floor slabs with columns and with each other under seismic influences.
  • the known system KUB-ZU in which the basic design solutions of the system of floor slabs with a column, a panel connection unit and a floor with columns are used.
  • the precast-monolithic reinforced concrete frame of buildings of the KUB-ZU series consists of vertical reinforced concrete columns and rigidly connected flat discs of interfloor and attic floors and coverings.
  • the disadvantage is the insufficient rigidity of the joints of the columns with the ceilings, created by welding through the connecting element, followed by monolithing with fine-grained concrete, which can easily collapse under seismic and other extreme influences; the disadvantage is also the need for a special conductor and a support table for installing the slab in the design position [www.kub3v.ru, patent holder SISTEMA STROY LLC, patents 100782, KP02020, JSTsl01065, 102652].
  • a hollow-core reinforced concrete slab designed to work in conditions of seismic activity which is a prototype.
  • the slab was obtained by the method of continuous non-formwork vibrocompression, contains oval voids, prestressed reinforcement in the form of parallel longitudinal bars and elements of transverse reinforcement, equipped with dowels on lateral surfaces.
  • the plate has reinforcing outlets of parallel longitudinal bars in the lower part from the side of its end, the plate is equipped with two pairs of additional longitudinal reinforcing bars placed in the bridges between the voids symmetrically relative to the longitudinal axis of the plate.
  • the disadvantages are: the absence of outlets on the sides and ends of the slabs, which makes it impossible to use in the SBK system, the absence of lifting loops in the slabs, which requires the purchase of additional expensive equipment, RF Patent 2363821.
  • the task to which the claimed invention is directed is achieved due to the fact that the design of the hollow-core slab without formwork and the compaction for the SBK system is made of concrete of a class not lower than B-25, is less labor-intensive in production and significantly reduces the production time, does not require alignment relative to the axes of the building, allows you to design and build multi-storey residential and public buildings according to the SBK system, reduces construction time, does not require racks, special conductors and support tables for installing slabs in the design position.
  • the technical result consists in reducing the construction time, reducing the production time of slabs dozens of times, reducing its cost by 1.5 times, in the installation of round-hollow slabs without formwork vibrocompression in earthquake-prone areas according to the SBK-SKF system of a prefabricated girder-free frame with seismic-insulating kinematic foundations, in the absence conductors, beams, girders and walls.
  • figure 1 shows a circular hollow-core slab 1 without formwork vibrocompression for the SBK system, which is formed with a "hidden girder" 2, with an embedded part 3, reinforced with high-strength wires 4, ropes 5, due to which the recommendations for preventing progressive collapse ...
  • the ropes are compressed with couplings 6 at the ends of the slabs 7 (shown in node A), which act as anchors in the concrete, and completely exclude the pulling in of the ropes after they are cut.
  • the couplings 6 can be installed after concreting, immediately before cutting the prestressed ropes 5, with tight support on the ends of the plates 1.
  • Ropes and wires can be replaced with composite reinforcement, while the anchoring at the ends of 7 plates 1 is carried out using adhesive joints.
  • Reinforcing rings 8 are driven into the hollow-core slab 1 without formwork, designed to support the precast bezel-less structure of the SBK.
  • the cut outlets of the ropes are crimped with double-length couplings 9 in a vertical position, as shown in section 2-2, high-strength wires 4 are welded together in order to create ring joints, which are formed in the “overderization joint”.
  • reinforcing half rings 10 are hammered into the freshly formed slab 1, followed by concreting of concrete of a class not lower than B-25.
  • ring rope slings 11 are used, fixed by the stranglehold method below the vertically located couplings 9, which squeeze the rope outlets 5.
  • Prestressed ropes, high-strength wires, or composite reinforcement are pulled over the stops.
  • Embedded parts 3 serving to install vertical ties of the building frame, and metal frames in order to form communication holes in slabs 1 are positioned with reinforcing pins so that when the slab is lifted after molding and cutting, the reinforcing pins remain in place.
  • the concreting is interrupted, the ropes are exposed, and a metal box with additional separate metal partitions is laid over the entire width of the bare ropes, to form blind ends.
  • the metal box is made with slots for installing reinforcing rings at the ends of the plates and passing the ropes.
  • Reinforcement rings and half rings are driven into the ends of the plates and side parts.
  • bare ropes, wires, or composite reinforcement are cut in the middle, formed into vertical half-rings, by crimping the joints of the ropes with couplings, welding wires, and composite reinforcement by gluing together.
  • the information confirming the possibility of carrying out the invention is the availability of the TENSYLAND EV5 model t-24 technological line worth $ 267,000 and a non-form vibrocompression unit with built-in vibrators and a heating system that allows the production of hollow core slabs.

Abstract

L'invention se rapporte au domaine de la construction et concerne notamment des dalles à creux multiples fabriquées selon un procédé de compactage vibrant sans coffrage, et destinées à une carcasse sans traverses à assembler pouvant être édifiée dans des conditions d'activité sismique. Les dalles comportent des creux ovales ou ronds. Les dalles sont armées à l'aide de câbles prétendus, de fibres haute résistance, avec des éléments d'armature transversale, et comportent des boucles en vue de leur levage. Les extrémités des dalles ont une épaisseur d'au moins 130 mm, ne comportent pas de creux et comportent des élément rapportés d'armature en forme d'anneau avec des câbles prétendus pincés par des couplages aux extrémités des dalles.
