Lightweight structural element

Abstract

The invention relates to a lightweight slab or similar structural element which can receive equipment that is accessible and that can extend through the slab. The invention comprises two main parallel reticular reinforcements separated by other secondary reinforcements that can be arranged to form a double diagonal, a single diagonal or be perpendicular in relation to the main reinforcements such as to form nodes with each main reinforcement, thereby forming a series of structural nodes. All of the reinforcements are embedded in a minimum volume of concrete fill which covers and protects said reinforcements and which is defined during the production thereof by a suitable formwork or mould which creates voids in a hypothetical prismatic volume and which is formed by hollow prismatic or truncated-pyramid-shaped volumes with smooth edges and vertices that improve structural strength and facilitate the extraction thereof when it is necessary to retrieve the moulds. The invention is characterised in that the aforementioned fill includes open holes (4, 3) in those portions that do not interfere with the secondary and main reinforcements and said fill forms: a succession of nodes connected at the top and bottom by holes that can be accessed from the lower and / or upper level (4); and, internally, cavities (2) connected by side holes (3) that form a network of channels in all directions, which can receive any type of equipment, such as electricity, telecommunication, plumbing, air conditioning or ventilation equipment.

Description

field of invention [0001] The object of the invention is a floor slab or similar lightweight structural element in which equipment can be laid. Background technique [0002] As the title suggests, the present invention is concerned with a slab - such as a reinforced structure, usually during construction with concrete filling and formwork elements to form the slab. [0003] Some building systems already employ this structure. They are usually hollow or solid members with no penetrability. The floor is placed on such a structure as described above, and the bottom of the structure places the ceiling or other terminations as required. Parts of the equipment (electricity, gas, telephone, water, etc.) are concealed in suspended ceilings or walls laid under the floor. These vacant spaces consume part of the building's cross-sectional area and, in many cases, have the same height as the living spaces. Typically, electrical wires, network cables, telephones, air-conditioning sys...
