OBJECT OF THE INVENTION
[0001] The present invention relates to a form panel and the use of the same for the erection
of roofs.
[0002] The panel, constituted in turn by panel members, is characterized in an external
sheet of stucco, so that it is not necessary to plaster the roof.
[0003] The panel is characterized in corrugated steel reinforcements which are mounted embedded,
so that the strength of the panel is improved.
BACKGROUND OF THE INVENTION
[0004] In general the conventional structures of roof formwork are constituted based on
props, between which wooden planks are inserted on which the concrete is poured.
[0005] Usually wood is chosen as the material of the form panels because the characteristic
roughness of the material facilitates the ensuing plastering of the roofs.
[0006] In all the systems known up to now after stripping the formwork plasters are applied
on the exposed faces with the object of forming the plaster finish.
[0007] The present invention discloses a panel and a use of the same which allows the roof
to be constituted at the time of erecting the formwork, with no need for later plastering
of the same.
DESCRIPTION OF THE INVENTION
[0008] The present invention consists of a form panel and of the use of the same for the
erection of roofs which eliminates the plastering stage signifying a saving of means.
[0009] These panels are constituted essentially of a stratified structure, composed in turn
by two panel members, a first lower panel of stucco and an upper panel of lightweight
concrete.
[0010] In the upper panel of lightweight concrete, in the part proximate to the panel of
stucco, longitudinal reinforcements of corrugated steel are embedded thereby increasing
the strength of the panel.
[0011] In the upper face the lightweight concrete panel has longitudinal grooves which facilitate
the grip between the panel and the framework concrete.
[0012] The concrete panel has in two of its sides on the face proximate to the stucco panel,
lateral rebates which facilitate transport and storage of the panels.
[0013] The worker can insert his hands in these rebates to carry and position the panels
without damaging the stucco area.
[0014] The panel of lightweight concrete is set back with respect to the stucco panel allowing
the concrete to reach the surface of the stucco panel.
[0015] The different panels are joined means of a perimetral tongue and groove arrangement.
[0016] The lightweight concrete allows the emplacement of halogen lamps and the opening
of recesses.
[0017] With the panel of the invention a roof is constituted by being able to place the
panels directly on a structure of struts. Members are placed on the panels which reinforce
and lighten the compression layer.
[0018] These members can be hollow blocks, continuous slab, or pans among others.
DESCRIPTION OF THE DRAWINGS
[0019] The present descriptive specification is completed with a set of drawings, which
illustrate the preferred embodiment of the invention without restricting the same.
[0020] Figure 1 shows a view in perspective of the panel of the invention.
[0021] Figure 2 shows a view in perspective of the panel of the invention with the concrete
panel cut to show the longitudinal reinforcements.
[0022] Figure 3 shows an example for use in the erection of roofs with the panel of the
invention.
PREFERRED EMBODIMENT OF THE INVENTION
[0023] In the light of the foregoing, the present invention consists of a form panel (1)
which is constituted in turn by a stucco panel (1.1) on which a panel (1.2) is located
of concrete lightened with expanded clay.
[0024] The panel (1.2) of lightweight concrete has longitudinal reinforcements (1.2.1) of
corrugated steel embedded therein, some grooves (1.2.2) in the upper face which facilitate
the grip between the panel (1) and the framework concrete, and some gripping rebates
(1.2.3) for better handling of the panel (1).
[0025] When making use of these panels (1) for the erection of roofs, the same (1) are placed
directly on the prop system (2) with the plaster face corresponding to the stucco
panel (1.1) facing downwards, with no need to use support plates.
[0026] When the panels (1) of the invention are in place, which are coupled by tongue and
groove joint (1.1.1), supports (4) are located on which the hollow blocks (3) are
placed, the supports are spacers of the hollow blocks (3) and the panels (1), which
blocks (3) are shown raised.
[0027] Between the hollow blocks (3) the space is left which the ironwork (5) requires to
constitute the supporting beams and the concrete covers the entirety of the assembly
until there is a compression layer (6) in the upper part.
[0028] The essential nature of this invention is not altered by variations in materials,
form, size and arrangement of the component elements, described in a non-restrictive
manner, sufficient for an expert to proceed to its reproduction.
1. Form panel (1) characterized in that it is constituted essentially by a stratified structure comprising in turn two panel
members, a lower first panel (1.1) of stucco to which is joined by its upper face
an upper panel (1.2) of lightweight concrete, the panel (1.2) of lightweight concrete
reveals embedded reinforcements (1.2.1), longitudinal grooves (1.2.2) in the upper
face, and rebates (1.2.3) for gripping; in the configuration of the edge, the width
of the concrete panel (1.2) is set back with respect to the stucco panel (1.1), the
latter (1.1) has a perimetral tongue and groove structure (1.1.1).
2. Form panel (1) according to claim 1 characterized in that the upper concrete panel (1.2) is lightened with expanded clay.

these structures the space is left which the ironwork (5) requires to constitute the
support beams, the concrete covers the entirety of the assembly until a compression
layer (6) is made on the upper part.
