Definitions
- the present invention concerns a procedure for making the foundations for a structure, such as halls, houses, bridges based on earth, using for foundations a ready-made concrete foundation slabtfhich is appropriate to serve as mould in concreting and which also contains the requisite steel reinforcements.
- the invention further concerns a foundation element for use in the procedure of the invention, which not only is appropriate to serve as mould in concreting and contains the steel reinforcement required in concreting but also is fit to be used in conjunction with the sleeve elements presently in common use in concrete technology.
- the structural design and shape of the foundation are dependent on the nature of the bearing ground. A structure standing on rock or on sandy soil may have a much simpler foundation than one on clay soil .
- foundations are nowadays most often made of reinforced concrete. If the bearing ground is at a depth of 2 to 3 metres, the building may be provided with foundations (slabs) sunk by excavation to this depth. If the bearing ground lies even further down, piling must be provided for foundation, the foundation slabs concreted on the site being arranged on their support.
- Slab foundations may also be applied in the case of simple bridges, where not only the bearing capacity of the ground is concerned but also the safety of the structure against toppling or slipping.
- the foundation structure then consists either of a separate slablike foundation element on which a sleeve, pillar or foundation beam element is fitted.
- Separate pillar foundation elements are also known, of which are available massive types resembling those concreted on site and types of reduced weight, where the pillar sleeve is connected to the foundation slab. It is also known in prior art to fit the pillar sleeve of an element structure together with a slab concreted on site.
- the invention is an attempt to eliminate the above-mentioned drawbacks associated with the use of foundation elements of prior art and of foundations concreted on site.
- the object of the invention is t ⁇ provide a procedure for making foundations of buildings and structures which is applicable both on ground without piling and on piled or otherwise reinforced ground; likewise the invention aims at providing a foundation element for use in the procedure which is also usable in conjuction with sleeve and other juncture elements known in the art.
- Fig. 1 presents a slab-and-sleeve foundation according to the invention, applied on ground with piling.
- Fig. 2 shows a slab foundation applied on the ground.
- Fig. 3 is an axonometric presentation of a slab mould element according to the invention.
- the foundation slab 1 of the invention may be manufactured in a plant, by conventional technique, in which case for reinforcement may be used conventional reinforcing steels and the "bottom reinforcement" (the principal reinforcement) consists of substantially horizontally placed single steels 2, which may be disposed e.g. crossing each other, to constitute a net-like structure. It is also possible to use ready-made steels with net configuration or equivalent which meet the requirements imposed on the foundations of structures.
- the dimensions of the reinforcement and the spacing of bars can be freely chosen, considering the stresses that will have to be borne.
- the side wail structure 6 of the foundation slab may be shaped to have desired thickness, as may the size and shape ⁇ f the foundation slab 1, to account for the loads which will be imposed on the ultimate structure.
- the foundation slab may have the cross section not only of a square but equally it may have a round, elliptic, rectangular or triangular crass section.
- the bottom reinforcement may be located in the bottom plane 7 of the side walls 6, but it to greatest advantage to place it higher than the bottom level of the side walls, and substantially horizontally.
- the bottom reinforcement 2 is anchored in the side walls 6 of the concrete mould.
- the foundation slab 1 of the invention can be transported from the works to the desired site, where it is applied on the ground 5, which may be piled 4 if necessary, in which case the foundation slab is applied in conventional manner upon cut-off piles 4.
- a sleeve 3 known in itself in the art, or other fixing elements, such as adhesion steels, formed steels, bolts, etc.; whereupon the slab mould is filled with concrete and the construction work may proceed in normal manner.
- the foundation slab element of the invention may be used in such objects where it was heretofore only possible to use foundation slabs concreted on site.
- the foundation slab element of the invention may be manufactured in series production in a plant and, moreover, type foundation slabs can be achieved with the result that it is possible to achieve conventional structures recurring in element prefabrication, whereby it becomes possible when selecting foundation slabs for a given construction job to select the element which is most appropriate for the particular loads involved, e.g. with the aid of tables.
- the foundation slab element of the invention is light, with the result that its transport and installation are easy and the transport and mounting costs are reduced from what they were for conventional foundation slab elements.
- the foundation slab of the invention constitutes the mould as well as the reinforcement and it reduces the work to be done an the building site, thereby facilitating and speeding up the construction work, and it requires less professional skill than before on the part of the builder, and it reduces the building costs.

Abstract
L'invention concerne un procédé de construction de fondations pour des structures telles que des halles, des maisons, des ponts ayant leur fondation sur le sol, utilisant comme fondation une dalle de fondation prête en béton appropriée pour servir de moule pour couler du béton et ayant également les renforcements nécessaires. L'invention concerne en outre un élément de dalle de fondation utilisé dans le procédé de l'invention, qui non seulement est approprié pour servir de moule de coulée du béton et contient les renforcements nécessaires pour la coulée du béton, mais est également approprié pour être utilisé conjointement avec des éléments tubulaires et autres éléments de jonction utilisés régulièrement de nos jours dans la technologie du béton. Selon l'invention, on applique sur un sol porteur (5) ou sur un sol renforcé par des piliers (4) un élément de dalle de fondation (1) préfabriqué en béton armé qui constitue un moule dans lequel ont été disposés un treillis en barres d'acier (2) sensiblement horizontalement et de préférence à une certaine distance du fond (7) des parois (6) de l'élément (1), de sorte que la dalle de fondation constitue à la fois le moule et le renforcement ou armature, sur laquelle on peut disposer un élément-manchon connu en soi dans l'art, ou autre éléments équivalents. L'élément de dalle de fondation de l'invention comprend un mur continu d'encerclement (6) et, à l'intérieur, une armature sensiblement horizontale (2) située dans le plan du fond de la paroi d'encerclement ou avantageusement à une certaine distance par rapport au fond de la paroi d'encerclement (6).The invention relates to a method of building foundations for structures such as halls, houses, bridges having their foundation on the ground, using as foundation a ready concrete foundation slab suitable for serving as a mold for pouring concrete and also having the necessary reinforcements. The invention further relates to a foundation slab element used in the method of the invention, which not only is suitable for serving as a concrete pouring mold and contains the reinforcements necessary for pouring concrete, but is also suitable for be used in conjunction with tubular and other connecting elements that are used regularly in concrete technology today. According to the invention, a precast reinforced concrete slab element (1) is applied to a load-bearing floor (5) or to a floor reinforced by pillars (4) which constitutes a mold in which a lattice has been placed. steel bars (2) substantially horizontally and preferably at a certain distance from the bottom (7) of the walls (6) of the element (1), so that the foundation slab constitutes both the mold and the reinforcement or armature, on which one can have a sleeve element known per se in the art, or other equivalent elements. The foundation slab element of the invention comprises a continuous encircling wall (6) and, inside, a substantially horizontal reinforcement (2) situated in the plane of the bottom of the encircling wall or advantageously at a certain distance from the bottom of the encircling wall (6).
