Description

Panel for the formation of structures for building.

Technical Field of the Invention

This utility model belongs to technical field of surfaces and panels used in construction, more specifically to the technical field of training of formwork for slabs and also of the construction of walls and partition walls.

Background of the invention

The panels used to make slab formwork is usually made using planks of wood, that although they suppose a low cost present the disadvantage of suffer a great deterioration, so rarely allow their reuse

They are also known from the state of the art panels for metal formwork, although they allow their reuse due to its high resistance have such a cost high that its use is very limited.

Utility Model ES1050033U, belonging to the same applicant of the present application, describes a panel for formwork consisting of a plastic material plate of small thickness and preferably rectangular contour that has reinforcement partitions on one of its surfaces that run perpendicularly between two of the opposite edges of the plate. These panels have the advantage of high strength and low cost, but have the disadvantage of being only usable on one of its surfaces since on the opposite run the reinforcement partitions.

Utility Model ES1052468U, also belonging to the same applicant of the present application, describes a formwork panel, which can be used for others constructions such as walls and partitions. This panel is formed by two equal plates of plastic material joined together by intermediate partitions to these of the same material that are parallel each other and perpendicular to the plates. These panels have more utilities that the previous ones to be able to use them for both surfaces, and are even used for the construction of walls and partition walls However, they have the disadvantage of manufacturing more expensive due to the need for the introduction of intermediate partitions between the plates. In addition, to raise the resistance of these panels, could be filled in their space interior by foaming or solid and compact materials depending on the needs, which increased its cost more still and difficult to manufacture, because first we had to perform the outer sheath with the interior partitions, and later, Enter the filling.

It was therefore desirable a system to solve the disadvantages existing in the previous state systems of technique

Description of the invention

The present invention solves the problems existing in the state of the art by means of a panel for formation of structures for construction, such as Recoverable or lost formwork for floors, and walls and partition, which has a substantially rectangular section with small height with respect to its length, and comprising a core interior that is formed by a plurality of cardboard sheets and an outer coating that surrounds the core and wraps it totally.

This outer covering is formed by glass fiber reinforced resins of different types. From this way, the core and the outer coating are linked in a single compound by means of the resins present.

This configuration has the advantage with respect the existing panels in the state of the art of a greater compactness and resistance without the need to include in the inside the panel filling elements or interior partitions to the panel structure.

In a preferred embodiment of the invention, The cardboard sheets of the inner core are reinforced with resins similar to those that make up the outer coating. These resins, in addition to increasing the resistance of the core and with she of the panel, grant greater compactness to it, since they contribute to the binding of the core and the outer coating forming a single compound.

The resins of the outer coating and the Core are a combination of rigid resins, semi-rigid, and flexible, and in one application Preferred of the invention may include additives such as internal release agents for, in the case of using the panels in formwork, allow the formwork without the need to use external additives They can also include additives to protect the product such as anti-shrink additives, sunscreens, antideformation, etc.

Description of preferred embodiments of the invention

As can be seen in figures 1 and 2, the panel for the formation of structures for construction object of the present invention has substantially section rectangular and with a small height with respect to its length, so Similar to conventional panels.

However, what differentiates this invention of conventional panels is the composition, given that the present panel is formed by an inner core 1 formed to in turn by a plurality of cardboard sheets 2, and a coating  exterior 3 surrounding the core 1 completely enveloping it. This outer coating 3 is made up of reinforced resins with glass fibers of different types, which give hardness and resistance to the whole.

The core 1 and the outer coating 3 remain completely bound in a single compact compound by means of the resins present, unlike the state panels of the technique, in which the exterior of the panel and the inside.

For the manufacture of the panels of the state of the technique, a reinforced hollow outer coating was made with internal reinforcement partitions, and the interior was filled with different materials such as foam or more materials compact depending on the degree of resistance desired.

Instead, the panels object of the present invention are carried out in a single phase, joining the elements casts, which facilitates and makes the manufacturing process cheaper. In addition, thanks to the core 1 formed by the cardboard sheets 2, it achieves high compactness and resistance on the board without the need to include partitions or back filling inside of any kind.

The resins of the outer coating 3 are a combination of rigid, semi-rigid, and flexible resins, and in a Preferred application include certain additional additives such as internal release agents. These internal release agents they are used in formwork panels, to allow correct formwork without the need for additives external Additionally they may include additives to protect the product such as sunscreens, anti-shrink additives and antideformation

In a preferred embodiment of the invention, the cardboard layers 2 that constitute the core 1 are reinforced with resins similar to those used in the outer coating. This embodiment provides the advantage of providing greater resistance. to the panel, while increasing its compactness, given that these resins contribute to the ligation of core 1 and the coating exterior 3 forming a single compound.
