Description

The invention relates to the field of lift pylons and particularly to the constituent elements of such pylons such as for example the splints allowing the joining of at least one upright with another upright and / or a cross-member in order to form a pylon. elevator.

Elevator towers provide the interface between the cabin and the building's own environment, the dimensions of which are subject to multiple variations such as number of floors, landing height, manufacturing tolerances, etc. The lift pylons have the function of ensuring the circulation and guiding of the cabin over the entire stroke of said cabin.

In known manner, for the design and manufacture of elevator towers, one uses either a technology based on steel sections of tubular or polygonal section, or a technology based on the folding and cutting of sheet metal. In the case of cutting and bending sheet metal, the building elements forming the elevator pylon have an open cavity delimited by a wall.

Conventionally, the elevator towers are formed of an assembly of several building elements of the upward or downward type forming an interior space sized to receive a cabin. The building elements are joined together by means of struts fixed on said building elements by bolts. The fishplates are positioned either outside, that is to say out of the interior space intended to receive the cabin, or inside, that is to say in the interior space intended to receive the cabin. Mechanical stresses of compression are exerted on the elevator pylon when the elevator is in operation, and even more so when the cabin is loaded.

These mechanical compressive forces result in shear forces exerted on the bolts fixing the splices on the construction elements, that the splints are positioned outside or inside the internal space of the lift tower, which weakens the elevator pylon at the junctions of the building elements.

The object of the invention is to remedy all or some of the aforementioned drawbacks. The invention relates to a lift tower construction assembly comprising: - at least a first rising-type construction element 35 having an open cavity, the open cavity being delimited by a wall having a receiving surface, 3025503 2 at least one splint shaped and arranged to at least ensure the junction between the first construction element and a second construction element of the up or down type, characterized in that the splice is shaped to be received at least partly in the open cavity of said first building element, and in that the splint comprises at least one wall shaped to fit at least the receiving surface of the first building element. Thus, by virtue of the invention, when mechanical forces are exerted on the building assembly, said forces are distributed over the entire section of the building element (s) against the fishplates which are positioned so that the building assembly is not weakened and that the bolting fixing the splint on the elements of constructions is much less solicited. Furthermore, another advantage lies in the fact that the shape of the fishplates allows the guidance and self-centering of the elements during assembly.

Preferably, the at least one wall of the splice is shaped to fit at least the receiving surface of the first construction element. According to a characteristic of the invention, the wall of the splice has at least one flange with a return forming a rail, the first construction element being configured to slide on said at least one flange.

According to a feature of the invention, the first building element comprises a plurality of fixing holes distributed along said first building element along a longitudinal axis of the first building element. Thus, it is possible to adjust the distance between the two building elements. In addition, the lift pylon is adjustable and then adapts to all 20 bearing heights. Preferably, the plurality of fixing orifices is formed on the return of one of the flanges of the first construction element. According to one characteristic of the invention, the first construction element and the second construction element are identical-shaped uprights. According to one characteristic of the invention, the first construction element is an upright and the second building element is a transom. Advantageously, the structural elements forming sleepers are of identical shape and thickness whatever the permissible load of the elevator. On the other hand, the length of the structural elements forming sleepers is variable and is a function of the load range and the dimensions of the cabin. According to a feature of the invention, the building assembly comprises a third riser-type building element extending in the same plane as the first building element, the first and third building elements being connected by a splice and the second construction element being attached to the splice connecting the first building element to the third building element.
