Abstract

The invention is about producing bearing semi prefabricated beams (14) strengthened so that they can be put on the shorts at bigger distance, at least 2,5 m. Inside one steel space truss (15) we can put at least another more steel space truss (16), which enables the increase of rigidity of bearing semi prefabricated beams (14). The distance between bearings beams are filled with hollow filler blocks-plates (1), constructed to enables the increase of height, rigidity and bearing capacity of intermediate floor construction. Hollow filler blocks are constructed to decrease transportation cost by even 50%. Hollow tiles (8) have an oval swell (11) on their vertical, shorter side (10) and oval groove (12), which is perfectly joined with groove (5) and swell (4) of hollow filler blocks (1).

Description

A GREAT SPAN INTERMEDIATE FLOOR CONSTRUCTION WITH SPECIAL REINFORCED SEMI PREFABRICATED SMALL BEAMS AND UNIVERSAL
FILLER BLOCKS
Technical Field
The subject of the invention, generally speaking, belongs to the field of civil engineering, or in to the field of intermediate floor constructions, especially to the filed of intermediate great span floor constructions. According to the International classifications of patents (ICP) the subject of the invention can be market with the following classification symbols: E 04 B 5/08, which is about bearing intermediate constructions build by prefabricated hollow elements, and with secondary classification symbols E 04 C 1-24 and E 04 C 5-065, which are about filling elements and steel lightweight lattices used in building intermediate floor constructions.
The Technical Problem
The technical problem is to be solved with the invention is: how to construct simple lightweight bearing intermediate floor construction span till 10 meters, with statically system of simple or continues girder with possibility of bearing. The system meant to be prefabricated so we can build completely adaptable enclosed space. Prefabricated girders must be lightweight for mounting; the strut frames must be put on greater spans. The volume of filling elements must be smaller, so that the transportation is easy and the price is lower.
Current State of Technology/Background Art
Intermediate floor constructions are made from wood, chute or prefabricated concrete plates. There are lot of intermediate floor construction, but the most similar to our construction are Monta, Fert or Omnia intermediate floor constructions, which is a lightweight construction. The spans of those constructions go to 6, 10 meters and there is no possibility to built continuous construction with them.
In Yugoslav patent treaty there is a document, numbered 31 900, about lightweight building construction made from prefabricated elements for floors. The construction is consisting of parallel, distanced girders and prefabricated lightweight panels among them. Groove on the upper side of panel is the base of following "I" girder. Glue made from mortar joins holders and panels. In Yugoslav patent treaty there is a document, numbered 34 215, about prefabricated building boards for double floors, intermediate floor constructions or roofs. Plate is made like plate vessel, which is filled with concrete. The concrete and board are forming constructions. These boards are similar to typical building elements made from steel and lightweight materials. This construction enables transmission of forces between bearing elements and prefabricated boards.
In Yugoslav patent treaty there is a document, numbered 41 269, about combed constructive element for facade constructions. Its construction is simple, the range of application is wide and the loading capacity is big. Elements are made from trough vessels and combs between them. The combs are made from steel, bending, perforated strips, which are joined to a lower vessel. The element is filled with self-extinction, polyurethane foam. The spans are greater than the other.
In Yugoslav patent treaty there is a document, numbered 22 622, about reinforced girder made from ceramic elements, joined by concrete. It is consist from lower side with a hollow for reinforcement and the upper side, joined by concrete mortar.
In our patent treaty numbered P-322/97 great span intermediate floor construction elements have a big volume; they are heavy and rather expensive, which gives us an idea to mace it better.
The Essence of the Invention
The semi-prefabricated system for intermediate floor construction is a combination of prefabricated and classical floor constructions, so it has the advantages of both of them. This system enables different spans between supports, up to 10 meters, and different bearing capacity. The essence of the invention is in production of special reinforced bearing beams. These prefabricated beams are mounted on building site on to the supports, shores or walls. Universal hollow plates are placed between these beams, enabling different ways of setting. Concrete build in construction, on the top of these plates, is forming monolith concrete plate, enabled to transmit horizontal forces to the walls in any direction, according to the rigidity of the wall itself. Hollow plates are constructed to enable setting in several rows, which increase the rigidity of the floor construction. On the intervals of 2 to 3 meters concrete reinforcing ribs are built in floor construction. Hollow plates are moving apart 15 to 25 cm, to form the base of those concrete ribs. Great span intermediate floor construction with special reinforced semi prefabricated small beams and universal filler blocks have several advantages over present intermediate floor constructions:
- It enables designing and building public, residential, industrial building, and even small bridges.
- It enables greater span between supports.
- It enables building continuous intermediate floor construction with favourable tension in few sections.
It is easy to transport and mounting it, without heavy machinery and highly qualified labour.
Universal filler blocks are smaller, which degrease transporting expenses up to 50% and the price of the floor construction up to 40%.

• Figure 1 is a universal hollow filler block.
• Figure 2 is a hollow tile

Detail Description of the Invention
This treaty is about special reinforced semi prefabricated small bearing beams 14, constructed by using at least one steel lattice 16, placed inside another steel lattice 15. These lattices are placed in the groove of hollow tile 8 and 8 a, according to figures 3 and 3 a. Then hollow tile is filled fine-grounded concrete of known quality. After hardening of concrete the special reinforced semi prefabricated small beams are done. The support can be put on at least 2, 5 m. In mounting beams are put on that support and strut frames on distance between 40 and 80 cm. Hollow filler element 1, plates, are put between beams, as it given at figures 5 and 6.
Hollow filler elements 1, plates, according to figure 1. have hollow, triangle-shaped supports, vertical walls 6 and oblique walls 7, joined with oval groove 5 on one side and oval swell on other side. Triangle-shaped supports are constructively- connected to trapeze- shaped hollows separated with oblique walls 2.
Hollow filler elements 1 are leaned on hollow tiles 8 or 8a. This hollow tiles 8 or 8a have lower plate 9, short longitudinal walls 10, groove 13 and oval swell 11 on one end and oval groove 12 on the other side, according to figures 2 and 3 a. Oval swell 14 perfectly subsides into oval groove 12 of the element 1.
Hollow filler element, plate 1 is completely practical, it is easy to put it on palette it, so the transportation of these elements is cheaper.
After mounting of great span intermediate floor construction, concrete is built in construction, on the top of these plates. So, it is forming monolith concrete plate, enabled to transmit horizontal forces to the walls in any direction, according to the rigidity of the wall itself.
Potential Application of the Invention in Industry or Elsewhere
All constructive and functional characteristics of the invention are successfully tested on the prototype.
