Description

METHOD OF INSTALLING ELEVATOR LEVEL DOORS

The invention relates to a method for installing elevator level doors as defined in the preamble of claim 1.

5

In some construction projects, it is possible to partially commission the building before all the floors and, for example, the elevator have been completed. In the commissioned floors, the elevator levels must be finished or at least the elevator shaft must be closed. In normal practice, elevator levels can only be finished after the elevator installation has been completed, in which case the elevator work easily delays the commissioning of the finished floors. Closing the elevator rooms with temporary solutions, on the other hand, causes additional work and thus increases costs.

It is previously known (patent application FI 873385, application date 4.8.1987) to install elevator doors already at the beginning of construction work. The doors are installed accordingly from the level with the help of bullet wires placed in the shaft. A hanging projection is used for the installation of the bullet wires 20, from which the bullet wires of the door installation hang in the correct proportions with respect to each other. Since according to the method, bullet wires cover the door opening, the installation of the doors must be done from the level and the doors must be transported to the levels. The positioning of the doors and the associated adjustment work is cumbersome because of the need to move heavy modules.

The object of the invention is to provide a simple and inexpensive method of installing doors, which avoids the disadvantages of the prior art and enables fast, accurate and reliable door installation.

The invention is characterized by the features set forth in the characterizing part of claim 1.

35 Instead of complete door modules, only the fastening elements of the door modules are initially installed, to which the dimensionally manufactured door modules are fastened as normal installation work. This avoids moving heavy and difficult-to-move door modules. In the adjustment phase, the door modules are out of the way of 86625 2 and in the door installation phase, bullet wires and the like can be removed from the door line. The door modules can also be easily transported through the shaft to the levels.

5 The installation of the doors is fast and thus does not interfere with the other construction process for a long time. When the door modules are manufactured in such a way that they adhere to each other, they form a single door line that is fire-safe.

The invention will now be described in more detail with reference to the accompanying drawings, in which Figure 1 shows a door module suitable for use in the method according to the invention. Figure 2 shows an elevator shaft in the invention, Fig. 5 shows the installation of the door modules in place and Fig. 6 shows another way of installing the door module.

Figure 1 shows a door module 1 suitable for use in the installation method according to the invention. The module preferably comprises the entire front wall of the elevator shaft for one floor space, which includes the frame, the wall parts, the doors, the control panels. The module is completely dimensionally complete before being brought into the shaft and protected by a suitable cover for transport and construction work 35. The door module may also comprise only the door frame to which the actual door is later attached.

The door module 1 has shoulders 2 which extend vertically outside the door module and are intended to fit into corresponding openings 14 in an adjacent door module or support member. According to the invention, abutment members 3, 5 are formed in the module, which are intended to be connected to fastening elements to be fastened to planar structures. There are at least two counter members and fastening elements, respectively, in the same horizontal plane in one door module. One module can also have response elements at several height levels.

According to Fig. 2, the mounting bracket 4 of the bullet wires 6 is fixed to the upper part of the elevator shaft 10 or a space above it such as a machine room and the second mounting bracket 5 to the bottom of the elevator shaft. If necessary, the mounting brackets can be moved to any point 15 in the height direction of the elevator shaft as required by the respective adjustment work to be performed. Figure 3 shows a top view of the positioning of the mounting bracket in the shaft. Instead of bullet wires, it is also possible to use, for example, optical aiming means. Laser probes are available in the market.

The positions of the fastening elements 8 of the door modules in the planes 7 are determined by means of bullet wires and according to the dimensions of the module. An appropriately shaped template can be used in the adjustment work, which determines the distance between the element and the wire, if necessary. When the fastening element is in exactly the right place, it is fastened to the planar structures permanently and reliably. The level structure is suitably a load-bearing structure on which the actual floor level is later made. The fastening element can be fastened not only to the cover of the structure but also to other suitable points.

Figure 4 illustrates in more detail a fastening element suitable for use in the invention according to the application. The element comprises a frame part 21 which is fixed to the gravel structures or walls of the building. An opening 23 is formed in the body part, within the permitted limits of which the part can be moved generally perpendicular to the door in the direction indicated by the arrows A-A. The body part can be fastened with bolts passing through the opening 4 8 6 62 5 or the like. Connected to the body part is a movable intermediate part 22, the position of which is adjustable mainly horizontally and perpendicular to the adjustment direction of the body part according to the arrows B-B. The intermediate portion 5 is connected to the stop member 24, which provides for securement door module connected in a height direction of the arrow C-C. The fastening element has the necessary clamping parts with which the stop member to be connected to the door module can be fastened in a positioned position. In principle, any corresponding element can be used as the fastening element, which can be adjusted to the extent necessary.

The installation of the door modules is illustrated in Figure 5. The fastening elements 8 have already been installed on pre-15 levels at this stage of the method. The bullet wire mounting bracket can also be in place for the next elevator installation steps. It can be used, for example, to position guides. Instead, the bullet wires have been moved to the side or completely removed during the installation of the door modules. At the lower part of the shaft, below the lowest level 20, a support member 12 is mounted, which is fastened in the same way as the door modules to the fastening elements or to the wall of the shaft. The support member 12 has a shoulder 13 which can be connected to a corresponding opening 14 at the bottom of the door module. The dimensionally manufactured door module 1 is lifted by a lifting device onto the support member 25 and fastened to the fastening element in exactly the right place. The door modules can preferably be brought into the elevator shaft either via the lowest level or by crane directly into the shaft. The fastening element can be used to make further fine adjustments later, if necessary.

Figure 6 shows an alternative way of installing the door module. In this case, the support member 15 is fastened to the upper part of the shaft and the door modules are fastened to the fastening elements starting from the top. This method is best suited when installing door modules for an entire 35 houses at once. Here, too, the transport of door modules can take place on different routes.

The invention has been described in detail above. The disclosure is not to be construed as limiting, but the scope of the invention is determined by the claims. For example, the method according to the invention can also be used at a later stage of construction, although not all the advantages it brings can then be fully exploited.
