Description

Scaffolding frame.

Object of the invention

The present invention is applicable fundamentally to the field of construction and refers to a framework of those used in the conformation of scaffolding.

It is an object of the invention that the framework for scaffolding is conceived so as to allow the release of platforms that are part of the scaffolding, without any need to disassemble the frames that are mounted at a level higher than the location of the platforms.

It is also the object of the invention that the means provided for this purpose, ensure the position of the platform and its release quickly and easily, at the same time that favor the structural rigidity of the frame.

Background of the invention

The frames used on the sides of a scaffolding are generally constituted by a structure closed formed by two parallel uprights linked by a upper crossbar and lower crossbar.

Platforms that are mounted on different levels on the scaffold and used as surfaces of operation, they usually have some hooks on their sides U-shaped inverted that fit on the crossbars superiors of corresponding facing frames.

These frames can have an upright series of multidirectional discs distributed to different heights that facilitate the union of the frame with the rest of the elements enhancing faster assembly in combination with greater rigidity and versatility of the system.

Multidirectional scaffolding systems do not require the platform as a structural element of the scaffolding so you can use fewer platforms for a determined assembly.

The position of the platforms is normally secured by means of frames that are mounted superiorly to the framework in which the platform is located. More specifically the lower crossbar of the upper frame is located immediately above the position of the side hooks of the platform coupled in a lower frame, so they will constitute a cap against which the hooks will contact avoiding the exit of the platform before a decoupling accidental of the same, returning the hooks of the platform to its coupling position on its frame.

This solution that favors the safety of scaffolding, however it is detrimental to the speed in the disassembly and operational versatility, since if required disassemble an intermediate platform must be decoupled necessarily the frames located on the level immediately upper, since its lower crossbars prevent the exit of platform hooks.

Description of the invention

The framework for scaffolding proposed in this invention comes to satisfactorily solve the problem previously exposed through the special configuration of the frame, which has two side uprights, a crossbar fixed superior and that stands out fundamentally for the incorporation of a movable lower cross member that can be placed immediately above the platform hitch means to prevent its extraction and that can be moved vertically upwards allowing the dismantling of the platform.

The power of movement provided by the movable lower cross member of a frame superiorly arranged to the frame in which the platform is mounted, allows for both the release of the platform without the need to disassemble the upper frame, it will only be necessary to move the crossbar mobile bottom to a suitable height.

The mobile lower cross member is provided with lateral guides at their ends that establish the bonding of the crossbar with each of the struts and facilitate the guided displacement of the crossbar in the vertical direction to these struts. The guides may consist of rings of diameter slightly larger than the frame struts for favor its guided displacement.

In correspondence with each of the guides side fixing means are found, such as a wedge, which fix the position of the guides on the upright and consequently the height of the mobile lower crossbar.

In the normal working position of the scaffolding, the frame will feature its lower mobile crossbar fixed by means of wedges in a low position immediately above the platform hooks that engage on the bottom frame, thus preventing the extraction of the platform.

To facilitate the release of the platform, the wedges of each of the the guides, raise the lower mobile crossbar and fix a new one position of the lower crossbar by means of wedges at a height enough to allow the platform to exit.

In case the guides are configured for a ring, it is provided that the ring has a radial extension in which a groove is defined that extends to the ring itself in which the wedge plays, which shifts in the groove between a coupling position in the that strikes the strut by setting the position of the ring and another release position where you stop contacting the strut allowing the displacement of the ring.

Description of the drawings

To complement the description that is being performing and in order to help a better understanding of the characteristics of the invention, according to an example preferred practical implementation of it, is accompanied as integral part of that description, a set of drawings where with an illustrative and non-limiting nature, what has been represented next:

Figure 1.- Shows a perspective view of the frame for scaffolding object of this invention.

Figure 2.- Shows a perspective view of the mobile bottom crossbar.

Figure 3.- Shows a detailed view of one of the ring-shaped guides with their fixing wedge.

Figure 4.- Shows a perspective view in the that the lower mobile cross member is observed in an elevated position regarding the platforms to facilitate the extraction of these last.

Figure 5.- Shows a perspective view similar to the previous figure in which the crossbar is visible lower mobile in lower position preventing the exit of the platforms.

Preferred Embodiment of the Invention

As can be seen in figure 1, the frame for scaffolding object of this invention is configured by two struts (1) linked by an upper crossbar (2) fixed on the which end coupling means (3) of a platform are mounted (4) horizontal, represented in figures 4 and 5, which couples by its other end in another parallel frame.

The framework for scaffolding stands out fundamentally because it incorporates a mobile lower cross member (5) that has guiding means (6) at its ends for movement vertical with respect to the struts (1), as well as having means of fixing (7) on the guiding means (6) that fix the position in height of the mobile lower cross member (5) relative to the struts (1), either in a lower position immediately above the coupling means (3) of the platform (4) that engages in the bottom frame to prevent the exit of it, as can be seen in figure 5, or in an elevated position, represented in the Figure 4, which allows the dismantling of the platform (4) without Need to disassemble the frame.

The guiding means (6) may consist of rings (6) of diameter slightly larger than the diameter of the struts (1) that have a radial extension (8), such and as seen in figure 3, in which a defined grooved (9) that also extends into the ring itself (6) in the which fixation means play (7).

The fixing means (7) may consist of a wedge (7) that moves in the groove (9) between a position of coupling where it strikes the strut (1) fixing the ring position (6) and another release position in which stop contacting the strut (1) allowing displacement of the ring (6).

Claims (2)

1. Scaffolding frame configured by two struts (1) linked by a fixed upper crossbar (2) on which end hooking means (3) of a horizontal platform (4) are mounted which engages at its other end in another parallel frame , characterized in that it incorporates a mobile lower cross member (5) that has guiding means (6) at its ends for its vertical displacement with respect to the struts (1), as well as having fixing means (7) in the guiding means (6) that fix the height position of the movable lower cross member (5) with respect to the struts (1) in a lower position immediately above the coupling means (3) of the platform (4) that engages in the lower frame to prevent its exit, or in an elevated position that allows the dismantling of the platform (4) without the need to disassemble the frame. 2. Scaffolding frame according to claim 1 characterized in that the guiding means (6) consist of rings (6) of diameter slightly larger than the diameter of the struts (1) that have a radial extension (8) in which it is located defined a groove (9) that also extends in the ring (6) in which the fixing means (7) consisting of a wedge (7) that moves in the groove (9) between a coupling position in the which strikes the strut (1) by setting the position of the ring (6) and another release position where it stops contacting the strut (1) allowing the displacement of the ring (6).
