DESCRIPTION:
BRIEF SUMMARY
The present invention relates to a method of assembling an elevator including a freight elevator (also herein referred to as a lift or goods lift) within a building and the assembly jigs used.
According to conventional techniques for assembling lifts in buildings, the lift or lifts are positioned when the structure of the building is finished and in particular when the lift shaft is formed. The equipment of the shaft (guide rails, doors and electric equipment for the lift) is positioned level by level from fixed or mobile scaffolding.
This method has the drawback of depending to a large extent on the erection of the building structure so that the beginning of lift assembly is tardy and so finishing of the lift is delayed. Furthermore, numerous adjustments must be made for adapting the lift to the building, particularly at the level of the thresholds of the floors of the building as well as the positioning of the guide rails.
The invention aims at overcoming these drawbacks and proposes a new method of assembling a lift or goods lift within a building, characterized in that it consists successively in : as the cabin guide rails and counterweight, the doors, the ducts, the electric equipment and ducts, on at least one assembly jig of predetermined height, such that they are disposed geometrically within the space of the jig with respect to each other in the exact position which they occupy when finally mounted in the support shaft; previously formed shaft bottom as far as the highest floor of the lift, in the support shaft which exists or is to be built; exists or mounting the shaft so that the fixing points for these elements are secured to the shaft during building thereof; support shaft;
This arrangements means that the construction of the lift or of the goods lift may begin prior to the erection of the structure of the building and such erection may be carried out from the lift shaft. In practice, the construction of the lift will precede that of the building by one to several levels and advantageously by two floors.
Furthermore, the method makes possible a considerable saving in time and labour on the worksite since the lift elements are already set in their final position on the assembly jig and it is only a question of fixing them without any other adjustment to the support shaft (existing or to be built).
Thus, it is no longer necessary to store equipment elements on the worksite and the work conditions are much better particularly in so far as the difficulties and safety of execution are concerned.
Finally, the lift is rapidly available and may serve as a worksite goods lift for the building under construction.
The invention also relates to the assembly jigs for said method They comprise a rigid structure, made from metal for example, developed so as to correspond to the profile of the shaft and essentially designed for carrying said lift elements and sliding along the walls of the lift shaft. This structure also carries scaffolding elements, such as working levels disposed successively heightwise and adjustable and which make it possible to carry out the tasks level by level in all safety. The height of the jig may be several floors but in practice it will be limited to two floors.
The invention also relates to the lift or the goods lift thus obtained.
One embodiment of the invention will now be described with reference to the accompanying drawings in which :
FIG. 1 is a perspective view of an assembly Jig according to the invention showing particularly the points at which the lift equipment elements are fixed to this jig;
FIG. 2 shows an equipped jig and its positioning in the shaft;
FIG. 3 shows the equipment elements fixed to the lift shaft, the assembly jig having been removed;
FIG. 4 shows schematically the construction of the lift with its partially built shaft relatively to the structure of the building, and
FIGS. 5 and 6 show respectively a guide rail fixing lug and sealing thereof in the wall of the shaft when the latter is made from cast concrete after positioning of the jig.
