Definitions

• the present invention relates to a method and a device for transporting and distributing materials and / or equipment on the periphery of a building.
• the invention is applicable in the technical field of construction or renovation activities of buildings or civil engineering works. It aims at a device complementary to a material commonly used by building professionals: scaffolding and walkways of various types used for work on facades.
• the distribution of equipment and / or miscellaneous materials around the periphery of the buildings in order to carry out work on the facades is carried out either using cranes, or by means of mobile lifting machines, from the ground, or even manually on the working gangway or the scaffolding floor.
• the cranes allow access to any point of the facade, but the cost price of their implementation for the execution of works on the facade is very high.
• the crane operator's lack of visibility on the façades opposite The crane is a serious source of danger. Because of these drawbacks, cranes are hardly used for carrying out facade work.
• Mobile lifting devices have a limited working height and allow good distribution of materials and equipment only if the circulation of said devices around the entire periphery of the buildings is possible, which in practice is rarely the case.
• At least one carriage is slaved to the railing of the bridge, creating between them a solid and sliding or rolling connection.
• the trolley is thus always held and guided, in its movements, by Le lodge-corps.
• the servo-control is achieved by at least one rolling part or sliding secured to the carriage and engaged on at least one Longitudi ⁇ nal element of the railing, preferably on the highest longitudinal element of said railing.
• the carriage-railing link makes it possible to transmit to said railing at least the horizontal forces of the device force diagram.
• the chassis of the carriage overlaps the railing and said framework is equipped with at least one wheel transmitting the weight of said carriage and its load to at least one longitudinal element of the framework of the railing .
• the weight of the carriage and of its load are transmitted to the framework of the floor of the gangway or of the scaffolding, by rolling or sliding the lower part of the carriage onto said floor.
• the body of the trolley can either be outside or inside the railing, or "straddling" the latter.
• the carriage finds, in the device, all or part of the stability necessary for the free positioning of the load it carries.
• the use of the trolley guided by the guardrail therefore allows the transport of burdens above it, or outside, without hampering traffic and work on the floor. It also allows, thanks to the guidance obtained, easy manual movement of loads, by simple push. It is also understood that the movements of the carriage can be easily motorized.
• the installation of the device of the invention on a self-climbing scaffolding creates a distribution system which, by the coordinated movements of the carriage and the gangway, covers the entire facade of the building.
• the movements of the self-climbing scaffolding can also be motorized.
• the trolley can be equipped with a container having a shape suitable for the loads which it is called upon to transport, this container being able to be provided with a device for unloading by tilting or the like whose movements or the action can be motorized.
• the mobile carriage is equipped with a lifting device, for example a cable winch, for hoisting the loads from the ground and bringing them onto said carriage; this action can be motorized.
• the trolley can be equipped with at least one device capable of carrying out work on the facades of buildings, or near said facades, in the case of buildings under construction. construction or renovation.
• the automatic movement and control of the carriage can be implemented to constitute an essential complement to the complete automation of certain machines, for example of machines intended to perform: Spraying of paints or coatings, Surfacing, Laying of plates, etc.
• Figure 1 shows, in cross section, a carriage rolling on the supporting frame of a gangway, outside thereof, being mainly guided and stabilized by the railing of said gangway.
• FIG. 2 shows, in cross section, another embodiment of the device of the invention, the carriage of which rolls on the floor of the bridge, being mainly guided and stabilized by the railing of the latter; the load transported being a projection machine.
• Figure 3 shows, in cross section, - a third embodiment of the device according to the invention, the carriage rolls on the upper rail of the railing, being mainly guided and stabilized by the lower rail thereof .
• Figure 4 is an elevational view showing the bridge equipped with the device of the invention, supported by a self-climbing scaffolding, said device being provided with a treu l whose cable is provided with an automatic load gripping device.
• Figure 1 shows a first embodiment of the device according to the invention which, in this case, comprises a carriage 1, the lower part is provided with one or more wheels 5b bearing on a raceway and Longitudinal guide 4a rigidly secured to the reinforcing elements 4b of the gangway 4 constituted by brackets fixing against the facade of the building, said raceway 4a being disposed on the outside of said elements, below the railing 3 of said passere lie .
• the carriage 1 In its upper part, the carriage 1 is provided with a slide 5a enclosing the upper rail 3a of the railing and mounted with a sliding ability along the latter.
• the carriage 1 carries a container 6 which, in this case, consists of a simple bucket.
• the wheel 5b or one of the wheels 5b when the carriage is provided with several wheels, is coupled to a motor 13 enabling it to rotate and to motorize the movements of said carriage, along the body.
• the vertical forces of the carriage and its load are transmitted by the wheel or wheels 5b to the elements 4a, 4b of the frame of the gangway 4, the longitudinal sections constituting the outer face of the gangway having a suitable shape allowing the introduction and movement of wheels 5b.
• the base of the carriage 1 is equipped with one or more wheels 5b bearing on the floor 4c of the bridge 4, which may include a tread and guide 4d disposed at near and along the railing 3.
• the carriage 1 also comprises, in its upper part, a slide 5a mounted with a sliding ability on the upper runner 3a of the railing.
• the carriage 1 carries an apparatus 11 for projecting a product on the facade 10 of the building; said carriage can however be equipped with one or more devices or machines allowing various fully or partially mechanized works to be carried out on the facades of buildings.
• the carriage 1 comprises a frame or frame 2 in the shape of a U which is placed "astride" on the upper rail 3a of the railing 3 of the gangway 4 installed in front of the facade 10 of the building.
• the chassis 2 is equipped with one or more pairs of wheels or rollers 5b inclined at 45 degrees to tangent
• the square section tube which, according to this embodiment, constitutes the upper rail 3a of the railing 3.
• the wheels 5b transmit to the railing the weight of the carriage 1 and its load and also part of the horizontal forces necessary for stability.
• the chassis of the carriage is provided with a slide consisting of wheels or rollers 5a with a vertical axis, rolling on the opposite vertical faces of the square section tube constituting the bottom rail 3b of the railing, so as to transmit the remaining part of the horizontal forces of the device to it.
• the carriage 1 carries a container 6 equipped with a tilting device 12 known per se, allowing easy reversal of the load transported by said container.
• the gangway 4 is constituted by The gangway of a self-climbing scaffolding 7 suspended or supported by a lifting device 7b with the masts 7a erected and held at the bottom of the construction 10 .
• the carriage 1 is of the kind which is illustrated in FIG. 3 and overlaps the railing. It is equipped with a motorized winch 8, the cable 8a of which is provided, at its end, with a device 9 for automatically gripping loads which, according to the example illustrated, are in the form of plates 14.
• the mobility of the carriage 1 makes it possible to take charges in a storage location which is organized and distributed around the periphery of the building and to deposit them at any point on the gangway surrounding the building.
