Abstract

Improvements in the object of the main patent nº 200001467 for: "Refinements in floor formwork, recoverable". The improvements include the provision of a system of retention hooks between the support beams of the floor formwork and the removable tilting beams, supported on said beams, for support of the formwork boards, allowing the vertical retention in suspension of the crossbars with respect to the beams after having made the tilting of said crossbars prior to disassembly.

Description

Improvements in the object of the main Patent nº 200001467 by: `` Improvements in floor formwork, recoverable. ''

The present Addition Patent application is refers to improvements introduced in the object of the Patent main 200001467 for `` Improvements in floor formwork, recoverable '', which come from the industrial practice of the object of said main patent and that provide novelty and inventive activity Regarding it.

The main patent refers to the provision of multiple crossbars for the support of boards or buckets of floor formwork that are susceptible to tilting at its ends when disassembling intermediate belts, which allows the recovery of the crossbars and the boards or cuvettes used for the formwork

Of the industrial practice of the aforementioned invention it has been observed that when disassembling an intermediate belt allowing the tilting and disassembly of the boards, said straps can come off abruptly by not being supported or retained, so it must be carried out effectively from the Bottom to avoid possible accidents.

To solve the aforementioned problem, have developed the improvements object of the present application of Addendum Patent, which allow automatic retention of formwork board support beams on the beams of clamping at the time of disassembly, preventing its fall fortuitous

To achieve its objective, the improvements object of the present invention provides that the wings of the beams in which rest the ends of the crossbars supporting the boards of formwork, present hook profiles associated with other profiles hook mounted on the lower side edges of the own crossbars, so that when you swing the crossbar in your disassembly, moving from horizontal position to position vertical, its associated hook-shaped profiles are retained of the hooks of the beams, allowing to retain the crossbars in suspension until such time as they manually separate from said position for withdrawal. This provides an important advantage of security since it is impossible for the crossbars of formwork may fall accidentally during disassembly presenting security risks.

The realization of the hook elements of the beams and support crossbars of formwork panels it will be variable, which may consist, for example, of the beams present in the lower retaining wings of the crossbars, some tabs directed upwards forming a certain angle with with respect to the horizontal, for example, 90º, joining the associated crossbar edges shaped profiles noticeably right angle with a profile wing ending in a hook that will be attached to the mentioned tab of the beam.

In other versions, you can resort to different precise shapes of hook couplings sides of beams and panel support crossbars Formwork

It can also be arranged in the elements horizontal associated to the beams cross-sectional tabs intended to center the support crossbars of the boards or You can even use the beams on the sides, instead of profiles that extend to full length, structures individual hooks in each of which may match a conjugated hook structure of a crossbar intended for support the formwork boards.

For your better understanding they are attached, by title an explanatory example but not a limitation, some figures of a preferred embodiment of the present invention.

A cross section is shown in figure 1 of a formwork for floors that incorporates the present improvements.

Figure 2 shows a perspective view of the elements themselves represented in figure 1.

Figure 3 shows a perspective view of a crossbar incorporated between two beams.

Figures 4 and 5 show two details in perspective of a crossbearer carrying the boards of formwork

Figure 6 shows a perspective view of a set of stringers and crossbars representing some of these in vertical retention position.

Figure 7 shows a detail of an embodiment of transverse partition walls of a crossbar.

Figure 8 is similar to Figure 7 showing the crossbar in disassembly position.

Figure 9 shows a perspective view of a set of stringers and crossbars with a series of crossbars in suspension position

Figure 10 shows a perspective view of a hook arrangement coupled to a side of a beam.

Figure 11 shows a perspective view that represents the relative position of stringer removed with respect to to the crossbar in the embodiment of Figure 10.

Figure 12 shows a perspective view of a set of stringers and crossbars in the execution variant of Figure 10

As can be seen in the figures, this invention provides for the constitution of hook systems, one of the which has been indicated with the numeral (1) as a whole between the beam (2) and the crossbars (2 '), (2' ') associated with it, intended to subsequently receive the formwork boards of floor.

In a preferred embodiment, the beam (2) it has lateral wings (3), (3 ') equipped with eyelashes directed upwards (4) and (4 ') on which the ends of the hooks (5) and (5 ') associated with the crossbars (2') and (2 '') so that, as can be seen on the right side of figure 1, the crossbar (2 ') will be arranged horizontally in working position, resting on the wing or element (3 '), allowing in this position the placement on the top of the formwork boards. When you want to disassemble the boards, we will proceed to tilt the crossbars (2 '), (2' ') to allow the release of the boards, not represented, with the characteristic that, when the hook profiles (1) are arranged, the crossbars (2 ') and (2' ') will be suspended from tabs (4) and (4 '), as depicted on the left side of the figure 1, observing the crossbar (2 '') in a vertical position held by the upper hook profile constituted between the lower wing (3) of the beam (2) and said crossbar (2``).

The realization of the hook structure may be variable provided that it allows the retention of the crossbars with with respect to the lower wings of the beams. So, for example, in the embodiment shown in figure 1, the hooks (5) and (5 ') they have a right angle profile structure fixed on an edge of the crossbars (2 ') and (2' '), presenting an end terminal (6) folded inward, at an acute angle or similar, to form the hook structure. A variant of the explained embodiment according to which some transverse inserts (7) and (8) are incorporated into the side (9) of a crossbar (10), being able to limit the position of the corresponding crossbar (11), whose hook structure (12) is fitted and by therefore held laterally between the plates (7) and (8) that can adopt structure of cartouche or others.

In another variant embodiment shown in the Figure 10, the arrangement of hook structures is observed separated on the side (13) of a crossbar (14), being integrated said separate hook structures, for example, by boxes (15) fixed as indicated on the sides of the beam (13), being able to receive the structures of hook (16) of the crossbars (17). Also in this case, it is due indicate that the precise shape of the hook structure (16) as well such as that of the conjugate box (15) may vary widely always fulfilling the characteristics provided in the present invention

Everything that does not affect, alter, change or modify The essence of the described improvements will be variable for the purposes of The present invention.
