Description

Reinforced flat structure, for support great weights

Object

The object to which the invention relates to Protects in this Patent, consists of a "Flat Structure reinforced, to support large weights. "

The structure is conceived for its use preferential as formwork for floor construction ("ironed"), although it may also have other applications as, for example, in shelves for large storage pesos.

In turn, the basic structure admits light variants in certain partial aspects that are later describe and that do not alter or distort its essentiality so which constitute "a group of related inventions in such a way that they integrate a single general inventive concept. " Therefore, in accordance with the provisions of Article 24.1 of the Law on Patents, are included in this same application.

Background

Flat structures are known, used as reusable formwork for the construction of floors, formed by wood edges that constitute thick edge boards for give them the necessary resistance so they can stand without warp the loads of the construction elements, until their setting.

As a consequence of its dimensions, and in particular of its thickness, turn out to be solid, weight boards relatively high, which makes handling difficult.

Moreover, because of the hygroscopic nature of its raw material, the boards can suffer deformations and since then, a rapid deterioration as a result of being subjected permanently at ambient conditions (humidity, temperature) Adverse

Description of the invention

The purpose of the invention that constitutes the object of this Patent consists in the overcoming of disadvantages of flat wooden structures for reusable formwork, previously described, having been designed and developed with this priority objective.

In a primary decision, it was decided to replace wood as raw material by moldable plastic or Extrudable, able to resist without appreciable consequences the tougher environmental conditions.

On the other hand, this allows you to choose with great freedom the design of the piece, to achieve its lightening without Decrease its rigidity and also recycle the entire structure in the case of uselessness.

In short, the claimed structure is formed by a parallelepipedic piece of low height, whose face top in use position is flat and is provided with numerous non-slip spaces of any shape, preferably ready to tresbolillo in rows and columns.

The lower part consists of streets Longitudinals intended to accommodate the formed reinforcements by preferably square steel tubes, limited to one side and another by series of equidistant cross-sectional tabs of bracing of the side walls of said streets, and of stiffening of the piece, defining an aligned set of cells.

In structures configured according to previous description, the reinforcement tubular reinforcements are introduced in their accommodation in the longitudinal streets from one end of these, making them slide until they reach the opposite, being guided in this displacement by the side walls and by three or more bridges, of passage sections adjusted to the outer section of the tubular reinforcements closing the ends of these by elastic plugs to prevent moisture from entering, the tubes being able to freeze once introduced, by the flaring of its ends.

According to a variant embodiment of the piece basic, also claimed, reinforcement tubular reinforcements they are not introduced into their housings by sliding them through the guided bridges, but are placed frontally on them with the piece in an inverted position, so it lacks such bridges, which are replaced by bolted fixing cores of the armors, whose ends are cut to bevel to favor their adaptation to these cores and create a countersink seat screw heads.

Description of a preferred embodiment

To clearly show nature and the scope of the advantageous application of the "Flat structure reinforced, to support large weights "which constitutes the object of the claimed invention, its description is described below. composition and arrangement of its component elements, making reference to the drawings that, to represent an embodiment preference of said object, for informational purposes, must be considered in its broadest sense and not as limiting the application and content of the claimed invention.

The claimed structure, which is plastic molded or extruded, it is formed by a piece small parallelepiped, whose upper face in position of use is flat and is provided with numerous spaces non-slip (1) of any configuration, preferably ready to tresbolillo in rows and columns.

The lower part consists of streets Longitudinal (2) intended to accommodate the reinforcement of reinforcement formed by preferably square tubes (3) of steel, said streets (2) being limited to one side and the other by walls lateral (4) braced by series of transverse tabs (5), which contribute to the stiffening of the piece and define a aligned set of rectangular cells (6).

The reinforcement tubular reinforcements (3) are introduced in their accommodation in the longitudinal streets (2) from one end of these, making them slide until they reach the opposite end, being guided in said displacement by side walls (4) and by three or more bridges (7), of sections of passage adjusted to the outer section of the tubular reinforcements (3).

The open ends of the reinforcements (3), are they close by means of elastic caps (8) to prevent the entry of moisture, being able to immobilize the tubes (3) once introduced in their housings, by means of the flaring (9) of their ends (Fig. 7).

In a variant embodiment of the piece basic, the reinforcement tubular reinforcements (3) are placed frontally in their housings being the piece in position inverted, which allows to suppress the guiding bridges (7) of the sliding armor for its introduction, occupying its place cores (10) intended for bolted fastening of each armor at its ends, finding these bevel cut for facilitate its adaptation to said cores (10) and with the face upper inclined inward to form countersunk (11) of seat of the screw heads (Figures 15 and 16).
