Description

Facade platform.

Object of the invention

The present invention relates to a facade platform, of the type that includes a structure horizontal with a first portion intended for disposal in cantilever with respect to the facade slab, presenting a flat surface with a folding hatch, and railings safety sides; and a second portion, intended for your support inside the facade slab, by means of fixing to said floor.

Field of application of the invention

The platform of this invention is applicable in the scaffolding, platform and media manufacturing industry Useful access elements in building construction.

Background of the invention

At present, several are known facade platforms, intended to allow access with loads of materials to the different floors or floors of a building in building. This access is made through the crane of the construction, which leaves the pallet with the materials in one portion or part of the platform protruding from the floor slab. These platforms have very limited security measures and the risk of operator fall is considerable for what they have done several attempts to improve its operability, and increase security measures thereof.

The utility model U200100951 is known for "Improved platform for unloading materials on site" which describes a platform comprising a quadrangular portion of tear plate fixed to a series of parallel straight portions and equidistant from structural tube, and that at their ends are fixed to two longitudinal profiles. Longitudinal profiles they extend in direct supports on an adjacent floor, and indirect supports through struts on the underside of the forged immediately superior. On the sides of the platform there are railings. On the open side of access to forged from the platform there is a practicable railing with bolt, consisting of two halves hingedly attached to each adjacent side railing.

This platform presents a consistent problem in which at certain moments of operation of the platform, the protection offered by the railings is not complete, since the user is located on the protruding surface without the protection that offers the practicable railing, for example when receiving a load of material, since you have to maneuver the hook or wafer of unloading of the crane, or when unloading said material. This is due to that the platform is still open at its front end.

This platform presents as an option that in its surface is a top hatch. This trapdoor allows you to open a hole in the flat surface that is suitable for the approach and passage of the crane cable to bring a load to a platform in a plant located under. Thus it is possible to place several different platforms stacked plants. The trapdoor remains in an upright or open position for the longest period of time, so as not to interfere with the download on other lower platforms, and only the position is lowered horizontal when downloading material on this platform specifically. In this embodiment, the trapdoor manipulation it is done directly by lifting and lowering it in position adequate, without adequate protection by having to open the practicable railing to access the anterior surface. In some cases the trapdoor is attached with a rope, so that manipulation can be done from behind the railing practicable, in order to improve safety, but this manipulation It is uncomfortable, forced and inefficient.

The applicant of the present invention ignores the existence of antecedents that resolve so satisfactory the exposed problem.

Description of the invention

The facade platform, object of this invention, presents some technical peculiarities destined to increase the security offered to the operator, by keeping it at all moment protected from the fall from the outside, and getting that Do not be exposed to spaces without the collective protection offered by the different railings that surround the platform.

The platform is of the type that includes a horizontal structure, with: - a first portion intended be cantilevered with respect to the facade slab, and that is endowed with a flat surface of plant in "U", being in the intermediate hollow of this flat surface a trapdoor collapsible with respect to a joint, finding railings safety sides, placed on both sides of the surface flat and - a second portion, intended for your support inside of the floor, by means of fixing means to said floor.

According to the invention, the trapdoor it presents at its front end a front railing, which is lowered together with said trapdoor between: a first position in the that the front railing is arranged vertically and the trapdoor in closed position, and a second position in which the railing front is arranged horizontally and the trapdoor in position open The platform comprises fastening means in the extreme folding positions to avoid opening or closing fortuitous trapdoor.

This platform incorporates a considerable technical advantage consisting of the built-in front railing to the trapdoor is always ahead of the operator, both in the horizontal closed position of the hatch as in the position raised open of it. This represents that in no moment the operator is exposed to the fall off the platform for lack of protection. This protection is exercised even when manipulate the trapdoor to close or open it.

In one embodiment, the horizontal structure it presents longitudinal guides on which a movable carriage between a pallet unloading position on the flat surface of the first portion and a resting position on the second portion of the horizontal structure.

The scrollable car allows once deposited the pallet with the load of materials, the hook or crane fork can be removed without the railing being a impediment, since said car makes it possible to move the deposited pallet into the floor or floor leaving said hook or free wafer to be removed.

However, this platform can be used in an effective and safe way without incorporating the mentioned car scrollable To do this, simply position on the platform a pallet that will be removed by a pallet truck, truck or similar, after the crane has deposited the load on said pallet As the pallet with the load is removed, that load is It separates and releases the hook or crane's cradle, so that the front railing does not constitute any hindrance during this operation.

The fastening means of the front railing they comprise first fastening pins in first ones lugs of the side rails, when the trapdoor is in An open vertical position. This allows to secure the trapdoor in the vertical open position, bringing the top of the front railing also establishes continuity of protection of the guardrails that are on the sides to the collective protection of the workers who work in the plant.

In turn, the fastening means of the front railing also comprise an articulated tubular support horizontally with respect to an intermediate part of said railing frontal. This tubular support is equipped with a few second pins lateral. The side rails have a second anchor lugs of the second pins of the tubular support when the trapdoor is open in an upright position. These second lugs are arranged in a lower position and more entered with respect to the platform floor, forming another bar or transverse protection element assimilable to a railing.

These pins are of any kind, but preferably they are shaped like bolts with springs for automatic operation on anchor lugs.
