Description

Formwork system

Object of the invention

This Utility Model refers to such as the statement indicates, to a formwork system, of the type that It is used in the formation of flat surfaces of elements of concrete constituting parts of works and constructions or other applications, which brings a series of improvements to relevant and advantageous features that will be reported more forward, compared to the current means used with equal or similar end.

More specifically, the new formwork system It is characterized by the simplicity of the link between the different pieces that constitute it, since there is no type of bolt, or other mechanism, avoiding the use to which it will be exposed and be in contact with concrete, which locks or mechanisms Stop working properly.

Background of the invention

As is known, to mold the concrete and contain it during the setting phase, racks of wood or metal of many different types.

Conventionally, type formwork recoverable that are used today for execution for example of the different floors of the constructions are constituted by a series of profiles and sopandas that are positioned at the height desired by the corresponding struts, on which they rest the boards and once the contour is closed, it is poured over They concrete.

The union of these structures is carried out normally by fitting existing protruding pivots in one of the elements to join in small entrances of the other element to join, with the consequent risk that with any small displacement can be released said union.

There are also other systems of union of different components of the formwork structure which consist of locking mechanisms or locks that advantageously they achieve greater security in their union, but frequently have the disadvantage that with use they deteriorate relatively soon when in contact with the concrete, being unusable and therefore presenting a useful life very short.

These mechanisms also represent in many cases a considerable increase of time in the realization of work which means an increase in cost, both for increase in labor time as per the replacement of deteriorated elements, which must be taken into consideration.

Explanation of the invention.

With the present invention, a system, whose fundamental objectives are to correct the inconveniences mentioned above, providing a formwork forming device distinguished by the simplicity of the link between its different pieces, which also allows of rapid assembly, recovery and reuse of different elements that constitute it.

More specifically, the new system of formwork, is constituted by a structure of the type that It mainly comprises two elements consisting of profiles, which are the quadrangular general section guides and the sopandas of quadrangular general section endowed, the latter, on both sides of outgoing two. The mentioned guides are the pieces that they serve to place at a certain distance and at the level set the rest of pieces. Upon them, once placed at corresponding level, are placed the sopandas that in turn serve to support the boards on them and at the same time to transmit to the struts the weight of the floor until the concrete sets and unclog

The mentioned sopandas are placed and fixed on the guides by introducing them between the various pairs of existing parallelepipedic projections every certain distance in the guides, in which, being of matching dimensions, they fit tight way. When unclogging, they recover by posture, it is that is, every time we totally form a plant, we recover 50% of the soups and 100% of the guides.

Depending on the need of the work, the mentioned highlights and therefore the sops, will be placed at a distance or another, allowing the system to form with lights between sops of different sizes, for example 2, 1.5 and 0.5 meters

Likewise, the link between the different sections of guide, is done simply by entering a protruding element, as a hook, on the bottom of one end of the guide in the resulting cavity another element existing bending at the bottom of the opposite end of the Another guide to link.

On the other hand, it should be noted that through using a brace, the system becomes a formwork totally braced in the place of interest, since it does not exist another element of coincidence that the placement of the strut in the guide. This achieves a system whose use is very simple allowing to work with complete security.

In this way, for the realization of the assembly of the formwork system of the invention, the hoist over the guide, and the brace is inserted through the tube to the guide strut, at which time the wedge of the brace on the sopanda proceeding later to the elevation of the formwork system at the proper distance.

For its part, in the process of decoupling, We will proceed as follows: First, the struts of the guides, then the braces, to allow the system stops being braced. Once the system It is not braced, you can recover all of the guides, finally, with the guides recovered, and according to the needs of the work, we proceed to unclog the soups that do not are accurate, leaving the rest until 28 days of setting concrete.

The new formwork system represents by consequently a simple and innovative structure of features structural and constitutive unknown so far for such end, reasons that together with its practical utility, endow it with sufficient basis to obtain the privilege of exclusivity that  It is requested.

Description of an embodiment of the invention

In view of the commented figures and agree with the numbering adopted, you can see in them a exemplary embodiment of the invention comprising the parts indicated below.

The new formwork system is constituted by a structure that, as can be seen in Figure 1, comprises two main parts consisting of profiles, the guides (1) and the sops (2). These guides (1), which serve to place the rest of the pieces at a certain distance and at the established level, have different pairs of parallelepipedic projections (3) placed every certain distance, depending on the need of the work, for example every 2 , 1.5 and 0.5 m. , between those that fit and fix the sopandas (2), as can be seen in greater detail in Figure 2.

\hbox{enlazar.}

In said figure 2, it can also be seen how the link between the different guide sections (1) is carried out in a simple way by introducing a hook-shaped element (4), existing in the lower part of one end of the guide (1), in the resulting recess of the angled element (5) existing at the bottom of the opposite end of the other guide (1 ') a

 \ hbox {link.} 

Once the guides are placed (19 at the level corresponding, they are placed, between the mentioned projections (3), the sopandas (2) which in turn serve to support them boards (6) and at the same time to transmit to the props (7) the weight of the slab until the concrete forges and disengage.

As can be seen in Figures 3 to 5, a brace (8), converts the system into a formwork totally bracing whose use is very simple allowing work with complete security, so that for the realization of your assembly, the sopanda (2) is placed on the ground on the guide (1), and the brace (8) is introduced through the tube for the strut (7) of the guide (1), then fixing the wedge of the brace (8) on the sopanda (2) proceeding later to the elevation of the system formwork at the right distance.

To proceed to the formless as it is observed in Figure 6, the struts (7) of the guides (1) are removed, a then the braces (8), to allow the system to stop Be braced. Once the system is missing braced, you can recover all the guides (1), and in  depending on the needs of the work, we proceed to release the sopandas (2) that are not precise, leaving the rest until the total concrete setting.

Describe sufficiently the nature of the The present invention, as well as how to implement it, is it states that, within its essentiality, it may be taken to the practice in other embodiments that differ in detail from the one indicated by way of example, and which will reach also the protection that is collected as long as it is not altered, change or modify its fundamental principle.
