FR2617217A1 - Buried cellar made of precast reinforced concrete - Google Patents

Abstract

The invention consists in overcoming the lack of a cellar for preserving foodstuffs in detached houses. It consists of a box structure made of waterproof concrete precast in the workshop and comprises a rim at its upper part 2 which prevents surface water from penetrating, an access orifice 4 supplied with a staircase 3 makes it possible to enter it, a ventilation duct 1 installed at each end enables it to be effectively ventilated.

Description

 The present invention relates to the creation of a prefabricated reinforced concrete cellar to be buried.

 The lack of cellars for storing wines and foodstuffs such as vegetables and canned goods in the individual houses built in recent decades poses real problems for their occupants.

 The present invention overcomes this drawback.

The invention consists of a reinforced pre-stressed concrete box, built and assembled in the workshop in order to provide it with a tight seal, having at its upper surface an opening allowing access to the interior. (4)
Access is by means of a staircase made up of 2 struts, also in prefabricated reinforced concrete, on which plates of the same material are fixed. (3)
A rim raised above the upper level of the box prevents the penetration of runoff water, this rim is located around the access opening. (2)
Ventilation nozzles covered with a cap are installed at each end of the length of the cellar, they allow effective ventilation avoiding condensation. (1)
The accompanying drawings illustrate the invention:
Line 1 represents the general aspect.

 Figure 2 gives the cross section.

 Figure 3 shows the cross-section.

 Figure 4 is the top view.

Depending on the version, the access point will be:
-Either free, in case the owner plans to build a small building above the stairs.

 - or covered with strong sheet metal plates provided with insulation inside and an effective closing system.

The insulation of the upper slab of the cellar can be achieved:
-by the exterior, using a layer of earth or concrete made from insulating material.

 -by the interior, by means of an insulator fixed to the plaiond.

The application of the present invention relates to:
-the houses built without cellars.

 -the houses built on a basement which frequently contains the central heating boiler raising the temperature too much to allow good conservation of wines and alients.

 -the houses of old construction provided with non-watertight cellars whose brutal upwelling makes it impossible to use.

 - future constructions, in this case the cellar is installed under the house or under the garage, at the location chosen by the owner, before construction.

Saui in the case of installation under the swimming pool, the upper level of the cellar can:
-be used as a terrace, if the cellar is installed against the house.

 - serve as a base for an annex construction which can be used as a workshop, chicken coop, shed, garden shed, etc ...

 The creation according to the invention is particularly intended for the conservation of domestic provisions.

Claims (3)
