[0045] Figure 1 shows an elevator building installation during construction of a building 100 at the beginning when the building has reached approximately 2 / 3 of its final height. Preferably, the installation of the elevator in Figure 1 begins when the building core has reached approximately 2 / 3 of its final height.

[0046] An open deck 101 and a temporary work deck 102 may be installed in the elevator hoistway 1, preferably by a builder. The open deck 101 may be a sloping waterproof deck that seals off the hoistway 1 to keep it clean and dry.

[0047] An elevator installer may install the protection decks 2, 2' from the working deck 102.

[0048] Figures 2, 11 and 12 show an embodiment of a protective deck 2, 2' that can be mounted inside the hoistway 1 and protects the part of the hoistway 1 below it from any possible falling objects.

[0049] The protective deck 2' shown in FIG. 11 differs from the horizontally arranged protective deck 2 in that it can be installed at an incline inside the hoistway 1. Thus, the protective deck 2' can be used as a top protective deck that can provide at least some of the functions of the open-air deck 101. The protective deck 2' shown in FIG. 11 can be installed at an incline inside the hoistway 1 to protect the part of the hoistway 1 below the protective deck 2' from objects and fluids falling during installation. The protective deck 2' can redirect or deflect falling material to minimize the impact of the falling object. The protective deck 2' comprises engagement members 4.1 and 4.2 that are engaged on both sides of the hoistway. With the protective deck 2' installed in the hoistway 1, the first engagement member 4.1 may rest on the threshold of the landing 20 and the second engagement member 4.2 may engage with the opposite wall.

[0050] The protective deck 2, 2' comprises a frame 4 attached to the walls 1a-1d of the hoistway 1. The protective deck 2, 2' comprises a cover 3 cooperating with the frame and extending substantially across the hoistway 1. The cover 3 is adapted to protect the hoistway 1 against objects and / or water falling into the hoistway below. The frame 4 is adapted to increase and / or decrease in size in at least one individual direction relative to a corresponding adjacent wall 1a, 1b, 1c, 1d of the hoistway 1 without removing it. The frame 4 is preferably made of telescopic beams 43 fixed to the walls with dedicated wall fasteners which can be positioned on each wall. However, corners are preferably provided to reduce the number of anchor bolts 41. The anchor bolts 41 preferably extend through holes provided in the walls of the hoistway 1, the walls of the hoistway 1 preferably being made of concrete. A preferred installation of the frame 4 includes drilling an anchoring interface 42 (wall fixing portion) into the corner and / or wall of the hoistway and attaching a frame fixing element 4' formed by the frame 4 to the anchoring interface 42.

[0051] The installation comprises a first hoisting set 6, also called hoisting device 6. The first hoisting set 6 is supported by the protective decks 2, 2' in Fig. 1 to Fig. 4 and by the ceiling 1' of the hoistway 1 in Fig. 5 and serves to hoist the elevator car 10 or the installation platform 80.

[0052] The first hoisting unit 6 may comprise a first hoisting machine 6a, also referred to as riding hoist 6a, and a first flexible tension member 6b, also referred to as hoisting rope 6b, movable together with the first hoisting machine 6a.

[0053] The installation comprises a hoisting point configured to support a car 10 or a placement platform 80 via a first hoisting machine 6a and a first flexible tension member 6b.

[0054] In Figures 2 and 3, a first embodiment of a hoisting point having a first diverter wheel 6c is rotatably mounted against the protective deck for supporting the hoisting ropes 6b.

[0055] FIG. 3 shows a second preferred embodiment of a hoisting point serving to support a hoisting rope 6b, comprising a connecting member 61 supported by the frame 4 of the protective deck 2, 2'. A rotatable diverting pulley 62 is supported by a hook 63 or a corresponding gripping member. The hook 63 can be connected to the connecting member 61 as indicated by the arrow A. The connecting member 61 may comprise a looplet / opening or a corresponding similar attachment means for use with the hook 63 or the aforementioned gripping member. Of course, the connection between the diverting pulley 62 and the protective deck may also be formed inversely, the connecting member may comprise a hook-like gripping member and the attachment means supporting the diverting pulley may each comprise a looplet or an opening. The diverting pulley 62 serves to guide and support the hoisting rope 6b.

[0056] According to one embodiment, the protective deck 2, 2' comprises a second hoisting set 5, also called material hoist 5, which lifts the building material below the protective deck. The material hoist 5 is supported by the protective deck 2, 2'. The material hoist 5 comprises a second hoisting machine 5a, also called material hoisting machine 5a, mounted on the protective deck 2, 2', preferably in particular on its frame 4, and a second flexible tension member 5b, also called material hoisting rope 5b, which is movable together with the material hoisting machine 5a. The material hoisting rope 5b performs the hoisting while being supported by the material hoisting machine 5a. The material hoisting rope 5b also comprises a connector 5b1 at its lower end, which is for example a hook that is connected or can be connected to the building material 8, 9 to be lifted. In the installation of FIG. 2, the connector 5b1 is connected to the building material 8, 9 to be lifted, which is a guide rail section.

[0057] According to an embodiment, the protective deck 2, 2' comprises a support beam 7 pivotally connected to the frame 4 and a second diverter wheel 71 attached to the support beam 7. The material hoist rope 5b is guided from the material hoisting machine 5a to the second diverter wheel 71, above it and from the second diverter wheel 71 downwards in the hoistway 1. More specifically, the support beam 7 is connected to the frame 4 pivotally about a preferably horizontal axis and also about a vertical axis x relative to the frame 4. Preferably, the position of the second diverter wheel 71 relative to the frame is adjustable by pivoting the support beam 7 about said vertical axis and / or about said horizontal axis. The protective deck 2, 2' comprises a third diverter wheel 72 guiding the material hoist rope 5b, allowing the rope 5b to pass from the material hoisting machine 5a to the second diverter wheel 71.

[0058] Figure 12 shows another embodiment of a protective deck with a material hoist 5 supporting the material directly without a support beam 7 for the material hoist ropes 5b. The material hoist ropes 5b may be suspended directly from a material hoist 5a mounted on a horizontally arranged or inclined protective deck.

[0059] The protective deck 2, 2' with auxiliary equipment can be used as a mobile installation tool for lifting heavy loads, for example a mobile elevator machine room located below the protective deck 2, 2', or an elevator car 10 or an installation platform 80 and building materials 8, 9 located below the protective deck 2, as shown in Figures 1, 2 and 4.

[0060] According to the two embodiments of the hoisting point shown in Figures 2 and 3, the first hoisting machine 6a can be mounted away from the protective deck 2, 2'. The first hoisting machine 6a may be mounted on the elevator car 10 or on the installation platform 80, and the first flexible tension member 6b passes around a diverting pulley 62 connected to the hoisting point 61.

[0061] The material hoist 5 may be used to lift car and counterweight guide rails and other heavy elevator components during elevator installation.

[0062] Once the protective decks 2, 2' have been installed and the hoistway 1 sealed off, elevator installation can begin in the lower section of the hoistway 1 below the protective decks 2, 2'.

[0063] In summary, at the bottom of the hoistway 1, which may cover about 2 / 3 of the final height of the hoistway, the car guide rail 8, the counterweight guide rail 9, the counterweight buffer assembly 11, the car buffer assembly 12, the counterweight (CWT) 13 and the working platform 10, 80 are installed in the pit 14. The working platform 10, 80 0 is used hereafter as the installation platform. The working platform 10, 80 moves with the help of the passenger hoist 6a, using the hoisting points 6c, 61 of the protective decks 2, 2'. The landing doors 15 and other elevator hoistway components are installed in the elevator hoistway 1. While the elevator is installed at the bottom of the building 100, above it, the construction of the building continues as usual, as shown in FIG. 4.

[0064] According to one embodiment, by car 10 is meant at least a part of a car, such as a car sling, which can be guided on the car guide rails 8. According to one embodiment, the working platform consists of a car with a car sling, which is complemented by a platform, such as an installer's working deck. According to one embodiment, the working platform consists of a car with a sling but without walls and a roof. According to one embodiment, the car comprises both walls and a roof. According to one embodiment, the car is a complete car. According to one embodiment, the working platform consists of the car 10 or at least a part of a car, which is guided on the car guide rails. According to one embodiment, the working platform consists of an installation platform 80. According to one embodiment, the lower section can be extended by moving the protective deck 2, 2' upwards in the hoistway 1, for example several floors above the landing 20, and further continuing the installation work of the lower section using the car 10 or the installation platform 80 supported by the protective deck as the installation platform.

[0065] Preferably, the installation is planned so that the lower section of the elevator shaft 1 is ready when the building reaches its final height and the roof 1' or ceiling is closed. After that, the open deck 101 (if installed) and the protective decks 2, 2' are removed from the shaft. In preparation for the elevator jump, the hoisting point 61 of the hoisting device, such as the passenger hoist 6a, is moved to the ceiling 1' of the shaft 1, as shown in FIG. 5. The installation of the elevator continues in the top section, as will be described in detail below, using the hoist installation platform of the car 10. The top section of the shaft 1 is only about 1 / 3 of the total height of the building, so the installation is completed quickly. Finally, the elevator hoisting machine 30 and the suspension ropes 31 are installed and energized. Thus, the elevator is ready for use in construction over the entire height of the building 100, as shown in FIG. 6 or FIG. 10.

[0066] More specifically, once the protective deck 2, 2' is in place, the overspeed governor 16 (OSG) and the riding hoist 6a are installed on the protective deck 2, 2', preferably working from the working deck 102. The overspeed governor 16 including the OSG upper pulley 17 is preferably laid on the protective deck 2, 2' via a lifting point 18 attached to the protective deck 2, 2' as shown by the arrow B in FIG. 7. The OSG rope 19 passes over the OSG upper pulley 17. The riding hoist 6a with the hoisting rope 6b is installed at the hoisting point 61 on the protective deck 2, 2' (FIG. 3). Preferably, the end of the OSG rope 19 and the end of the hoisting rope 6b are temporarily delivered and placed at the landing 20 of the building 100.

[0067] The material hoist 5 may be installed on top of the protective decks 2, 2'. The working deck 102 may be removed and the ends of the OSG ropes 19 and the hoisting ropes 6b may be lowered to the pit 14. Guide rails 8, 9 are positioned in the pit. The guide rails may be raised and lowered using the material hoist 5.

[0068] The first rungs of the guide rails 8, 9 are neatly installed in the pit area by suitable surveying equipment, preferably a guide rail surveying tool is installed on the protective deck 2, 2'. The CWT and car buffers 11, 12 are installed in the pit. The OSG lower pulley 17' with OSG tension weight is installed. The CWT 13 with frame 13' partially, preferably 40% filled with CWT filler 21 and with at least one CWT pulley 13" is installed guided by the CWT guide rails 9.

[0069] According to an embodiment, the car 10 is installed inside the hoistway 1 so as to be guided by the car guide rail 8. The car 10 may comprise a car sling with upper and lower beams. The OSG rope 19 is fixed to the car by the OSG rope end 19' and guided around the upper and lower OSG pulleys. A parapet 10' is attached to the car. A safety gear is connected to the car sling and the OSG rope 19. An automatic safety gear trigger (ASGT) is attached to the car 10. The ASGT engages the safety gear automatically in case of breakage of the hoisting rope or manually when necessary to ensure the safety of the car. A passenger hoist 6a is attached to the car 10.

[0070] The car 10 with the passenger hoist 6a is moved and used as a setting platform to set up the guide rails for the car and the counterweight, preferably up to the protective deck, according to a vertical line formed, for example, by a weight wire attached to the protective deck or by a surveying laser tool. Preferably, the car 10 is used for lifting the guide rails. The guide rails may be lifted using the material hoist 5. The guide rails can be installed using guide rail lifting clamps that lift the respective rails. The guide rails may be installed through the protective deck, which can later be removed from the roof of the car 10. Suitable openings for the guide rails may be drilled in the protective deck cover 3.

[0071] Using the car 10 as an installation platform, the landing doors 15 may be installed, preferably from the third floor upwards, to the top floor of the lower section, and each door (if any) may be energized, preferably simultaneously. A bottom landing door may be installed. The elevator hoistway and pit may be energized below the protection deck. Also, a landing call station may be installed at each floor 20 of the lower section.

[0072] The car 10 may be parked at the top of the lower section and secured in place, as shown in FIG. 4, by activating the safety gear and using a parking chain.

[0073] According to one embodiment, the lower section can be extended by moving the protective deck 2, 2' higher in the hoistway 1, for example by several floors above the landing 20, which is shown in the situation from Fig. 4 to Fig. 5. Thus, at least one elevator jump over the initial lower section during installation can be performed before supporting the car 10 or the installation platform 80 from the ceiling 1' of the hoistway 1. In connection with the jump over, the overspeed governor 16, the material hoist 5 and the hoisting point 61 can remain supported by the protective deck 2, 2' and the OSG rope 19 can be extended or replaced. When moving the car 10 with the passenger hoist 6a and using the car 10 as an installation platform, the guide rails and further elevator equipment can be installed in the area below the protective deck on top of the raised lower section, as described above for the initial lower section.

[0074] In preparation for the installation of the upper section of the elevator hoistway and the jumping over of the elevator to the upper section, the open deck 101 can be removed (if installed) to prepare for the removal of the protective deck. The material hoist 5 and the cover 3 can be removed from the protective decks 2, 2'.

[0075] Following the work from the roof of the car 10, the overspeed governor 16 and the passenger hoist 6a are put into motion. The overspeed governor rope 19 is detached from the OSG lower pulley 17' and the tension weight, pulled to the car roof and taken out of the hoistway 1. The OSG 16 is removed from the protective decks 2, 2'. The hoist rope 6b is unwound from the hoistway and taken out of the hoistway. The diverting pulley 62 can be removed from the protective decks 2, 2'.

[0076] Provision is then made to support the car 10 or the installation platform 80 from the ceiling 1' of the hoistway 1 so that the car 10 or the installation platform 80 can serve as an installation platform for the upper section of the hoistway after the elevator has jumped over.

[0077] The diverting pulley 62 and the hoisting rope 6b are installed so as to be suspended from the hoistway ceiling 1', for example via a threaded bolt bolted to the ceiling. The OSG 16 may be suspended by the structure of the building 100 during installation of the upper section.
