Description

Precast concrete panel.

Object of the invention

The present invention, as its own title indicates, refers to a precast concrete panel specially designed to save big lights and withstand loads high, while presenting optimal fire resistance in all points of the floor, even at the start and endings of it where usually other panels offer important deficiencies

Precast concrete panels subject to this invention is mounted horizontally aligned and concreted on site together with a compression layer of the floor, which It is supported by the beams defined by the panels themselves.

This panel fits both in the field of civil engineering, as in building, in anyone who due to their special characteristics they demand the use of a piece with these properties.

Background of the invention

In the current prefabricated panels, for improve fire resistance concatenate several elements resistant, which by adding their properties provided a fire resistance according to current regulations; however, this solution poses deficiencies in startup and completion of wrought cloths, since in these areas only available one piece, so that fire resistance is weakened in those areas

Document ES-2117499 is refers to a prefabricated panel for flat beam slabs, which they are concreted on site together with a compression layer of forged, which presents a configuration in "pi" in which the extreme wings have approximately half a width than the wing intermediate between the two supporting beams.

Document ES-2145659 describes also a prefabricated panel for slabs of flat beams, in this case provided with an inverted "U" configuration, with side beams of straight exterior walls, which when left attached to the assembly, they would improve fire resistance.

Document U256083 describes a panel that is used as a building enclosure comprising a landfill insulated interior made of expanded polystyrene.

Description of the invention

This panel presents a general configuration in "T", in which the width of the vertical frame that forms the structural beam has approximately an equivalent width ¼ of the panel assembly, which provides some features resistant capable of withstanding high loads reaching the 8 meters of light. This central beam comprises inside: a central band of expanded polystyrene and along it a interdistanced, open-wing "U" armor series outwards, which inferiorly, in their interior angles, support longitudinal reinforcement paths, which are positioned within the concrete strategically at a great distance from the exterior, which makes this piece reach great resistance to fire.

U-shaped armor that is placed at length of the nerve or central beam to support the armor Lower longitudinals rest on an electro-welded mesh placed horizontally, which is embedded in the horizontal part of the panel assembling the concrete in this area.

Description of the figures

To complement the description that is being performing and in order to facilitate the understanding of characteristics of the invention, is attached herein descriptive a set of drawings in which, with character Illustrative and not limiting, the following has been represented:

Figure 1 shows a sectional view vertical of the panel object of this invention.

Figure 2 shows an elevation view of a Forged formed with several terraced panels of this type sideways.

Preferred Embodiment of the Invention

As can be seen in the figures referenced precast concrete panels (1), object of this invention is mounted horizontally aligned and concreted on site together with a compression layer of the floor. In the heads, between two consecutive panels longitudinally forms an intermediate beam that is concreted in joint work with the slab, the set forming a succession of beams longitudinal (those defined by the panel itself) and transversal (trained on site) that effectively resist the weight of the structure and deposited on it.

Each of these panels (1) presents a general "T" configuration, in which the width of the frame vertical that forms the structural beam (2) presents approximately an equivalent width ¼ of the panel assembly (1). To lighten the panel, a band is placed longitudinally inside expanded polystyrene core (3), which has a equivalent configuration, preferably trapezoidal or rectangular.

Along the panel, in the vertical frame that form the structural beam (2), a series of reinforcements are observed in "U" interdistanciadas (4), with wings spread out, that inferiorly, in their interior angles, support paths longitudinal reinforcements (5), which are strategically placed at a distance from the outside that makes this piece reach great Fire resistance.

As can be seen in the figures, the "U" trusses (4), which are placed along the nerve or central beam (2), rest on an electro-welded mesh (6), which horizontally and is embedded in the horizontal zone of the panel (1), assembling this area.

Once nature is sufficiently described of the invention, as well as a preferred embodiment, for the appropriate purposes that the materials, form, size and arrangement of the elements described may be modified, as long as this does not involve an alteration of the essential features of the invention claimed in continuation:

Claims (2)

1. Precast concrete panel, which are mounted horizontally aligned and concreted on site together with a compression layer of the slab, characterized in that it has a general "T" configuration, in which the width of the vertical frame that forms the beam Structural (2) has approximately ¼ equivalent width of the panel assembly (1), and inside it comprises: a central band of expanded polystyrene (3) and along it a series of interdistanced "U" reinforcements (4) , with wings open outwards, which inferiorly, in their interior angles, support longitudinal reinforcement paths (5), which are strategically located at a distance from the outside that makes this piece reach great resistance to
fire. 2. Prefabricated concrete panel according to the preceding claim, characterized in that the "U" reinforcements (4), which are placed along the rib or central beam (2) are supported by an electro-welded mesh (6), which are placed horizontally and is embedded in the horizontal area of the panel (1).
