According to the invention, the modular elements are carried out by mould injection of a synthetic foam comprising polyurethans, polyamides, polyethylene, polypropylene, polyvinyl chloride, polyvinylidene chloride, aminoplast resins, phenol resins, silicones, expanded polystyrene, extruded polystyrene or sodium silicate and are of two types: a. core modular element having a parallelipipedic shape with square cross section, with outer dimensions of 120/70/70 cm and the thickness of wall (1) of 10 cm, the detachable cover (2) of the modular element being joined with the base through a a 5-cm thick cut-out, being provided with one or more holes having the diameter of 20 cm, and b. modular corner element with dimensions of 70/70/70 cm with the wall thickness of 10 cm, the joining cut-out being also of 5 cm and with a single hole in the cover, said hole having a 20 cm diameter. The claimed foundation consists of assembled modular elements, wherein, through the holes (5) in the covers there is cast concrete or another construction material. The process claimed by the invention consists in locating and assembling the modular elements in the space destined to the foundation, followed by casting, through the holes (5) in the covers, concrete or other construction material which fills the inner side of the modular elements and is hardened.

Description

Modular elements for foundation, completely insulated foundation and construction process /

The invention relates to modular elements for fully insulated building foundations, to a completely insulated foundation and to a process for making a completely insulated foundation.

Concrete insulated concrete forms (ICF) are well known for high performance insulated concrete wall assemblies and environmentally friendly materials that have greatly improved energy efficiency, durability, air quality and comfort of inhabited structures.

An example of such a system is disclosed in U.S. Pat. No. 4,423,501, which claims a form of insulated concrete wall containing a plurality of blocks arranged in connected rows. Each block includes a pair of insulated panels arranged in parallel. The disadvantage of this process is the long time required to assemble the elements for such a construction.

U.S. Patent No. 5,536,669 discloses a system of thermally insulated molds for pouring mortar and obtaining a foundation wall. The disadvantage of this system is that the foundation is not insulated at the bottom, which causes heat loss.

U.S. Pat. No. 4,128,881 describes insulated T-shaped building blocks which are laid on the foundation and then poured into them. This system of insulated blocks cannot be used in the construction of insulated foundations.

US5174083 describes a system of concrete molds for pouring mortar and obtaining foundations with perimeter insulation. The disadvantage of this procedure is that it does not ensure the complete insulation of the foundation.

The problem solved by the invention is to provide a system of modular elements which, when assembled, allow the concrete to be poured simultaneously and the foundation to be completely insulated.

The object of the invention is to obtain a completely thermally insulated unitary foundation by pouring a material which hardens into a cavity resulting from the assembly of modular elements.

The modular foundation elements according to the invention eliminate the above-mentioned disadvantages in that they have a parallelepiped cavity inside determined by a rectangular base and a cover with at least one hole.

The completely insulated foundation according to the invention eliminates the above-mentioned disadvantages in that it is obtained by pouring a material which is strengthened in the network formed by assembling the modular elements for the foundation.

The process of obtaining a completely insulated foundation removes the disadvantages mentioned above by the fact that it consists of assembling the modular elements for the foundation and pouring a material that hardens in the space determined by assembling the modular elements for the foundation.

The modular foundation elements according to the invention are made of synthetic foams based on polyurethanes, polyimides, polyethylene, polypropylene, polyvinyl chloride, polyvinyl chloride, aminoplast resins, phenolic resins, silicones, expanded polystyrene, sodium silicate.

The material that is reinforced by casting in the space determined by assembling the modular elements for the foundation is concrete, reinforced concrete, polyester resins, epoxy resins, polyurethane resins.

By applying the invention, the following advantages are obtained:

-creating a completely insulated foundation without formwork elements through a simple and economical process;

-short foundation construction time compared to traditional procedures;

-total insulation of the foundation and reduction of heat loss.

The following is an embodiment of the invention in connection with Figures 1, 2 and 3 which represent:

Fig. 3 Modular corner element for the foundation consisting of the lower body (3) and the cover (4) with a round hole (5).

Example 1. The modular elements for the foundation (figures 1,2,3) are made of fire-retardant polyurethane foam, by injection into the mold and expanding to the size of the mold.

The modular elements have the following dimensions:

the modular element for the foundation (fig. 1,2) has the dimensions: 120/70/70 cm with two holes in the lid with a diameter of 20 cm.

the corner modular element for the foundation (fig.3) has the dimensions 70/70/70 with a hole in the lid with a diameter of 20 cm.

Using the modular elements for the foundation, a square foundation with a side of 12 meters is made as follows: the modular elements for the foundation are assembled (fig. 1, fig.2, fig.3) and then poured into the cavity formed by the modular concrete elements. B 250.

After the concrete has hardened, the resistance to the load-bearing wall is over 120 tons / linear meter.
