[0042] Such a protective deck can also be used to protect installers within the hoistway. It can also be used to provide an installation platform at the bottom area of the upper section.
[0043] Once the building reaches 1 / 4 to 3 / 4, preferably 1 / 2 to 3 / 4, and most preferably about 2 / 3 of the total building height, the protective deck can be installed and elevator installation can begin immediately. This reduces the elevator installation period after the building's total height is completed. Once the building reaches its final height, only 1 / 4 to 3 / 4, preferably 1 / 2 to 3 / 4, and most preferably about 2 / 3 of the installation work remains before the elevator can operate at normal speed and be delivered to the customer. The completed elevator can be delivered to the customer sooner. [Brief explanation of the drawings]

[0045] Figure 1 shows elevator construction equipment during construction of building 100 at the beginning when the building has reached approximately two-thirds of its final height. Preferably, installation of the elevators in Figure 1 begins when the building core has reached approximately two-thirds 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 the builder. The open deck 101 may be a sloped, waterproof deck that seals off the hoistway 1 to keep it clean and dry.
[0047] The elevator installer may install the protection decks 2, 2' from the working deck 102.
[0048] Figures 2, 11 and 12 show embodiments of protective decks 2, 2' that can be mounted inside the hoistway 1 and that protect the part of the hoistway 1 that is below the protective deck from any possible falling objects.
[0049] The protective deck 2' shown in FIG. 11 differs from the horizontally positioned protective deck 2 in that it can be installed at an angle inside the hoistway 1. Therefore, 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 angle inside the hoistway 1 to protect the portion of the hoistway 1 below the protective deck 2' from falling objects and fluids during installation. The protective deck 2' can redirect or deflect falling material to minimize the impact of the falling object. The protective deck 2' includes engagement members 4.1 and 4.2 that engage with both sides of the hoistway. When the protective deck 2' is installed inside the hoistway 1, the first engagement member 4.1 can rest on the threshold of the landing 20, and the second engagement member 4.2 can engage with the opposite wall.
[0050] The protective decks 2, 2' comprise frames 4 attached to the walls 1a-1d of the hoistway 1. The protective decks 2, 2' comprise covers 3 cooperating with the frames and extending substantially across the hoistway 1. The covers 3 are adapted to protect the hoistway 1 from objects and / or water falling into the hoistway below. The frames 4 are adapted to increase and / or decrease in size in at least one individual direction relative to the corresponding adjacent walls 1a, 1b, 1c, 1d of the hoistway 1 without requiring their removal. The frames 4 preferably comprise telescopic beams 43 secured to the walls by dedicated wall fasteners that can be positioned on each wall. However, corners are preferred to reduce the number of anchor bolts 41. Preferably, the anchor bolts 41 extend through holes provided in the walls of the hoistway 1, which walls are preferably constructed of concrete. A preferred installation of the frame 4 includes drilling anchoring interfaces 42 (wall fixings) into the corners and / or walls of the hoistway and attaching the frame fixing elements 4' formed by the frame 4 to the anchoring interfaces 42.
[0051] The installation comprises a first hoisting unit 6, also called hoisting device 6. The first hoisting unit 6 is supported by the protective decks 2, 2' in Figures 1 to 4 and by the ceiling 1' of the hoistway 1 in Figure 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 the car 10 or the installation 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 to support the hoisting ropes 6b.
[0055] 3 shows a second preferred embodiment of a hoisting point serving to support a hoisting rope 6b, comprising a connecting element 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 element. The hook 63 can be connected to the connecting element 61 as shown by arrow A. The connecting element 61 may be provided with a looplet / opening or a corresponding similar attachment means corresponding to the hook 63 or the aforementioned gripping element. Of course, the connection between the diverting pulley 62 and the protective deck may also be formed in reverse, with the connecting element being provided with a hook-like gripping element and the attachment means supporting the diverting pulley each comprising a looplet or opening. The diverting pulley 62 serves to guide and support the hoisting rope 6b.
[0056] According to one embodiment, the protective deck 2, 2' is provided with a second hoisting device set 5, also referred to as a material hoist 5, for lifting building materials 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 referred to as a material hoisting machine 5a, mounted on the protective deck 2, 2', preferably on its frame 4, and a second flexible tension member 5b, also referred to as a material hoisting rope 5b, movable together with the material hoisting machine 5a. The material hoisting rope 5b performs the suspending function while being supported by the material hoisting machine 5a. The material hoisting rope 5b also has a connector 5b1 at its lower end, which is, for example, a hook connected or connectable to the building materials 8, 9 to be lifted. In the installation of FIG. 2, the connector 5b1 is connected to the building materials 8, 9 to be lifted, which are guide rail sections.
[0057] According to one 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 hoist machine 5a to the second diverter wheel 71, above it, and from the second diverter wheel 71 downward through the hoistway 1. More specifically, the support beam 7 is connected to the frame 4 pivotally about a preferably horizontal axis relative to the frame 4, as well as about a vertical axis x. Preferably, the position of the second diverter wheel 71 relative to the frame can be adjusted by pivoting the support beam 7 about the aforementioned vertical axis and / or the aforementioned horizontal axis. The protective deck 2, 2' comprises a third diverter wheel 72 that guides the material hoist rope 5b, allowing the rope 5b to pass from the material hoist machine 5a to the second diverter wheel 71.
[0058] Figure 12 shows another embodiment of a protective deck with a material hoist 5 that supports 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 that is mounted on a horizontally or inclined protective deck.
[0059] The protective decks 2, 2' with auxiliary equipment can be used as mobile installation tools for lifting heavy loads, such as the mobile machine room of an elevator located below the protective decks 2, 2', or as shown in Figures 1, 2 and 4, an elevator car 10 or an installation platform 80 located below the protective deck 2, and building materials 8, 9.
[0060] According to 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 attached to the elevator car 10 or to 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' are installed and the hoistway 1 is sealed, 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 approximately two-thirds of the final height of the hoistway, the car guide rails 8, counterweight guide rails 9, counterweight buffer assemblies 11, car buffer assemblies 12, counterweight (CWT) 13 and working platforms 10, 80 are installed in the pit 14. The working platforms 10, 80 are hereafter used as installation platforms. The working platforms 10, 80 move with the help of the passenger hoist 6a, utilizing hoisting points 6c, 61 on 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, construction of the building continues as usual above, as shown in Figure 4.
[0064] According to one embodiment, the term "cab 10" refers to at least a part of a cab, such as a cab sling, which can be guided on the cab guide rails 8. According to one embodiment, the work platform consists of a cab with a cab sling, which is complemented by a platform, such as an installer's work deck. According to one embodiment, the work platform consists of a cab with a sling but without walls and a roof. According to one embodiment, the cab has both walls and a roof. According to one embodiment, the cab is a completed cab. According to one embodiment, the work platform consists of the cab 10 or at least a part of a cab, which is guided on the cab guide rails. According to one embodiment, the work 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 continuing the installation work of the lower section using the cab 10 or the installation platform 80 supported by the protective deck as an installation platform.
[0065] Preferably, the installation is planned so that the lower section of the elevator hoistway 1 is ready when the building reaches its final height and the roof 1', i.e., ceiling, is closed. The open deck 101 (if installed) and the protective decks 2, 2' are then removed from the hoistway. 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 hoistway 1, as shown in FIG. 5. As will be described in detail below, the elevator installation work continues in the top section using the hoist installation platform of the car 10. Because the top section of the hoistway 1 is only about one-third of the total height of the building, installation is completed quickly. Finally, the elevator hoisting machine 30 and suspension ropes 31 are installed and energized. Thus, the elevator is ready for use throughout the entire height of the building 100, as shown in FIG. 6 or FIG. 10.
[0066] More specifically, once the protective decks 2, 2′ are in place, the overspeed governor 16 (OSG) and passenger hoist 6a are installed on the protective decks 2, 2′, preferably working from the working deck 102. The overspeed governor 16, including the OSG upper pulley 17, is preferably routed to the protective decks 2, 2′ via a lifting point 18 attached to the protective decks 2, 2′, as shown by arrow B in FIG. 7. The OSG rope 19 passes over the OSG upper pulley 17. The passenger hoist 6a, with the hoisting rope 6b, is installed at the hoisting point 61 on the protective decks 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 can be installed on top of the protective decks 2, 2'. The working deck 102 can be removed and the ends of the OSG ropes 19 and hoisting ropes 6b can be lowered to the pit 14. Guide rails 8, 9 are positioned in the pit. The guide rails can 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 with suitable surveying equipment, preferably a guide rail surveying tool is installed on the protective decks 2, 2'. The CWT and car buffers 11, 12 are installed in the pit. An OSG lower pulley 17' with an OSG tension weight is installed. A CWT 13 with a frame 13' partially, preferably 40% filled with CWT filler material 21 and equipped with at least one CWT pulley 13" is installed so as to be guided by the CWT guide rails 9.
[0069] According to one embodiment, the car 10 is installed inside the hoistway 1 so as to be guided by the car guide rails 8. The car 10 may include a car sling having an upper beam and a lower beam. An OSG rope 19 is secured to the car by an OSG rope end 19' and guided around 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 a hoisting rope breakage 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 an installation platform to align and install guide rails for the car and counterweight, preferably up to the protective deck, for example, according to a plumb line formed by a weight wire attached to the protective deck or using 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 may be attached using guide rail lifting clamps that lift each rail. The guide rails may be installed to penetrate the protective deck, which may then 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, landing doors 15 may be installed, preferably from the third floor upwards, up to the top floor of the lower section, and each door (if any) may be energized, preferably simultaneously. A bottom landing door may also be installed. The elevator hoistway and pit may be energized below the protective 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 Figure 4 by activating the safety gear and using the parking chain.
[0073] According to one embodiment, the lower section can be extended by moving the protective decks 2, 2' higher in the hoistway 1, for example, several floors above the landing 20, as shown in the situation in Figures 4 to 5. Thus, before supporting the car 10 or the installation platform 80 from the ceiling 1' of the hoistway 1, at least one elevator jump above the original lower section during installation can be performed. In connection with the jump, the overspeed governor 16, the material hoist 5 and the hoisting point 61 may remain supported by the protective decks 2, 2', and the OSG ropes 19 may be extended or replaced. When moving the car 10 with the passenger hoist 6a and using the car 10 as an installation platform, guide rails and further elevator equipment may be installed in the area below the protective deck above the raised lower section, as described above for the original lower section.
[0074] In preparation for the installation of the upper section of the elevator shaft and the jumping over of the elevator to the upper section, the open deck 101 can be removed (if installed) and the protective deck can be prepared for removal. The material hoist 5 and 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 hoisting machine 6a are put into operation. The overspeed governor rope 19 is detached from the OSG lower pulley 17' and tension weight, pulled to the car roof and removed from the hoistway 1. The OSG 16 is removed from the protective decks 2, 2'. The hoisting rope 6b is unwound from the hoisting machine and removed from 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 installation platform 80 from the ceiling 1' of the hoistway 1 so that the car 10 or 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 socket bolt bolted to the ceiling. The OSG 16 may be suspended by the structure of the building 100 during installation of the upper section. In the case of a machine room-less elevator, the OSG 16 is installed to be suspended from the hoistway ceiling 1', for example, by bolting a stud bolt to the ceiling. Alternatively, in the case of an elevator with a machine room, as shown in Figure 10, the OSG 16 may be installed to be suspended from the machine room 50.
[0078] The hoisting ropes 6b and OSG ropes 19 are lowered onto the car roof. The hoisting ropes 6b are driven via a passenger hoist 6a, which is attached to the car, preferably to the upper sling beam of the car. The OSG ropes 19 are attached to an OSG rope end 19' and are guided around the OSG lower pulley 17' by a tension weight in the pit 14, adjusting the length of the OSG rope 19. An Automatic Safety Gear Trigger (ASGT) is attached to the car.
