Description

Technical Field

[0001] This disclosure relates to elevators, and more particularly to templates for installing elevator hardware in multi-story buildings having elevator openings formed in the periphery of each floor slab without requiring a reinforced concrete (RCC) shaft. Background Technology

[0002] Today, elevators are an essential part of multi-story buildings, such as commercial and residential buildings. Elevators are typically used in various configurations, which can be deployed within a building based on factors such as estimated passenger load, traffic flow, building size, elevator location, and car layout. One of the most important factors to consider when installing an elevator is its location. In fact, planning the elevator's location within the building during the initial stages of construction is crucial. This is because buildings currently include elevator shafts (such as RCC C2- / 25) formed by concrete walls to accommodate the installation and movement of the elevator. Since any modifications or corrections at later stages can cause significant inconvenience and incur substantial costs, it is essential to determine the shaft location only in the initial stages (e.g., when designing the building's superstructure). Once these shafts are constructed, the elevator's location is permanently fixed, and the builder cannot alter its position without major reconstruction.

[0003] Furthermore, once the shaft is constructed, the elevator's orientation cannot be changed. This is because the builders need to leave space at each floor for installing landing doors so people can enter the elevator. Since the shaft is made of RCC concrete, this space will only be provided during the construction of the superstructure and cannot be reoriented at a later stage without significant reconstruction. Therefore, the builders also lack the flexibility to change the elevator's orientation at a later stage.

[0004] Similarly, using RCCs in the construction well directly increases the overall construction cost of the structure. Firstly, RCCs are expensive. Secondly, the construction of RCC wells requires additional labor, which also leads to a significant increase in overall labor costs. Furthermore, the total time required to complete the construction of the structure also increases.

[0005] Furthermore, in an RCC shaft, various sub-components (such as elevator guide rails and mounting brackets) are directly mounted on the inner surface of the RCC shaft. Therefore, installation of these sub-components can only be performed while they are physically present within the RCC shaft. Typically, a support platform is required within the RCC shaft so that personnel can stand at predetermined locations within the shaft and install the various sub-components. This platform is also raised using a lifting device to allow for smooth movement within the shaft, thus enabling the installation of sub-components at different heights. This significantly increases the overall complexity of the installation process. In fact, the installation time is also longer. Moreover, because personnel are present within the RCC shaft, additional measures are required to ensure their safety during the installation of the elevator and associated sub-components. This increases the total cost of installing an elevator in a building.

[0006] WO 2013 / 186096 A1 describes a method and installation system for installing lifting components of a hoisting system in a building shaft, wherein the installation system is movable within the shaft. The hoisting system has at least one cage that can travel along guide rails within the shaft. The installation system positioned in the shaft includes a support platform and an installation platform, as well as a lifting and pulling device, the support platform and installation platform being arranged one above the other. The support platform and installation platform are alternately fixed in place within the shaft, and at any given time, the platform not fixed in place is vertically displaced relative to the platform fixed in place by means of the lifting and pulling device. As mentioned above, the lifting components need to be installed in a building shaft (such as an RCC shaft). This significantly increases the overall construction cost of the building and leads to various disadvantages associated with the implementation of an RCC shaft for elevator installation as described above. Furthermore, in order to install the lifting components in the shaft, support platforms and installation platforms are required to assist the assembler in installing the lifting components at different locations within the shaft. This significantly increases the overall complexity of the installation process. In fact, the installation process takes a considerable amount of time. Furthermore, because the assemblers are located inside the RCC well, additional measures are required to ensure their safety during the installation of the elevator and associated sub-components.

[0007] In buildings without RCC shafts, the location for elevator hardware is limited to the surface of the building's floor slabs. Hardware can be installed by drilling holes into the RCCs in the floor slabs and screwing the hardware into nuts and / or bolts inside the holes. Nuts and bolts can be wedged or glued into the holes to transfer loads to the floor slabs. For structural integrity and load bearing capacity, additional concrete reinforcement is used to strengthen the floor slabs around the elevator opening. Therefore, drilling around the elevator openings carries a greater risk of impact with the reinforcing bars. The concrete reinforcement may cause the drill bit to stop or deflect, resulting in incomplete drilling and / or misaligned holes. To mitigate this, hardware with larger fixation tolerances is required. Additionally, drilling into RCCs is noisy, dusty, and rapidly wears down the drill bit.

[0008] Therefore, it is necessary to simplify the installation of elevator hardware (especially in buildings that do not require RCC shafts) to reduce or eliminate the associated disadvantages mentioned above. Summary of the Invention

[0009] Specifically, the object of the present invention is to provide a template for installing elevator hardware in buildings (particularly buildings without structured RCC elevator shafts), and the aim is to eliminate the associated disadvantages mentioned above. According to the invention, this object is achieved by a template having the features of claim 1, an elevator having the features of claim 11, and a method for installing elevator hardware having the features of claim 12.

[0010] According to a first aspect, a template is disclosed in this invention for installing elevator hardware in a building, particularly in buildings with unstructured (RCC) elevator shafts. The template is adapted to be aligned with the shaft, which intersects with the floor slabs of the building. The template includes an array of anchor points adapted to anchor the aligned template to the floor slabs, a pattern of mounting points adapted to mount hardware to the aligned template, and a frame connecting the anchor points and the mounting points, wherein the frame is adapted to be arranged laterally offset relative to the shaft, which intersects with the floor slabs.

[0011] Elevator hardware can be, in particular, fixed and permanently attached to the building. The hardware may include, for example, a bracket for connecting the elevator's guide element to the building. This bracket is configured to transfer loads from the guide element to the building. Specifically, the loads to be transferred to the building may be primarily or partially horizontal loads. Vertical loads may be primarily supported by the guide element itself. The guide element may be rails or profiles for guiding the elevator car and / or counterweight, or thresholds for guiding the elevator landing doors.

[0012] The elevator shaft can be a clear space including the travel path for the elevator's moving components. These moving components can be at least one car, at least one counterweight, and a traction member connecting the car and the counterweight. The shaft can intersect with all floors connected by the elevator. The shaft can be formed by vertically aligned, substantially similar elevator openings within the floor slabs of the connected floors. All sides of these elevator openings can be closed by the floor slabs. Alternatively, the elevator openings can be open to at least one side. The elevator openings can have a larger clearance than the shaft. The lower end of the shaft can terminate in an elevator pit, and the upper end can terminate at the headroom.

[0013] The floor slab can be the body of an RCC, having an upper surface that forms the floor slab layer and a lower surface that forms the ceiling layer below.

[0014] The frame can be a structured element. The frame can be made of metallic materials, particularly sheet metal or profile metal. The frame can have a shape corresponding to at least one side of the elevator opening. Specifically, the frame can correspond to multiple sides of the elevator opening. The frame can have a larger clearance than the shaft, for example, between 1% and 10%. The frame can have a geometry or profile that is equal to or corresponds to the profile of the opening in the plate forming the shaft. For example, the frame can be rectangular.

[0015] Anchor points can be located on or within the frame. For example, an anchor point can be a hole for bolts. This hole can be slotted to allow for minor misalignment adjustments to the formwork. Anchor points can be located at a distance from the edge of the elevator opening. The frame may require fewer bolts than individually secured hardware. Mounting points can also be located on or within the frame. Mounting points can be holes for bolts. Mounting points can be threaded, or nuts can be attached to them. Mounting points can also be unthreaded. Unthreaded mounting points can also be slotted to allow for minor misalignment adjustments. Mounting points can replace drilled holes in the floor slab. Mounting points can be located closer to the edge than anchor points. Mounting points can be located close to the edge because a minimum thickness of concrete is not required between the edge and the mounting point, as with drilled holes.

[0016] At least one of the anchor points may be characterized as an anchor configured to be poured in situ during the pouring of concrete for the floor slab. Concrete can be poured into the formwork shell. This process can be referred to as setting. The mixed but uncured concrete flows around and embeds itself into objects inside the formwork shell. As the concrete sets, these objects fuse firmly into the concrete. In particular, the object is reinforcing steel. The object can also be an anchor. Embedded anchors can have very high load capacities. The load capacity can be higher than that of drilled anchors. Thus, fewer anchors can be used to support the load of the hardware. Anchors can be aligned by aligning the formwork with the shaft before pouring concrete. Anchors can be bent bars, T-bars, U-bars, threaded bars with washers and nuts, welded anchors, or anchor bolts. Due to threaded anchors, the anchor point can be a slot in the frame to allow for adjustment after the concrete has set.

[0017] At the anchorage point, anchors (and especially the anchors mentioned above) can be welded to the frame. These anchors are configured to be cast in-situ when concrete is poured for the floor slab. The anchors can be integral components of the frame. The anchors can have some undercut to transfer loads to the concrete. Welded anchors can be non-removable, especially in rough construction environments. At least one, and preferably at least two, anchors can be arranged on one side of the frame. Alternatively, the at least one anchor can be a component integrally formed on the frame. Therefore, the anchors can be made of metal material, particularly sheet metal or metal profiles, together with the frame. Such anchors can be embedded in or embedded with the floor slab. After alignment, the anchors can extend vertically. However, it is conceivable that the anchors extend horizontally or in other directions.

[0018] The frame can be configured to project at least partially horizontally into the shaft opening in the floor slab, for example, by a few centimeters, such as between 1 cm and 20 cm, preferably between 2 cm and 10 cm. The opening can be larger than the shaft, for example, by a few centimeters, such as between 1 cm and 20 cm, preferably between 2 cm and 10 cm. In this way, the frame can still be arranged outside the shaft. Mounting points can be located within the protruding members. The protruding members can be accessed from both sides. Within the protruding members, the mounting points can be unthreaded holes, and the hardware can be attached using nuts and bolts. Even if the frame is made of low-carbon steel, the mounting points can withstand higher loads using nuts because the nuts are made of the selected material. By using mounting points inside the opening, the size of the hardware can be reduced due to the reduced need to bridge gaps to the floor slab.

[0019] The template may include at least two plumb line points for aligning the template with the shaft and for aligning the template with other templates located on other floor slabs of the building. The plumb line points may be arranged spaced apart on the frame and may be adapted to project into the shaft opening. A plumb line is a very efficient and inexpensive solution for vertically aligning an object. Using two plumb lines, an object can be aligned in two dimensions. The plumb line is attached to a plumb bob. By gravity, the plumb bob will be truly vertically aligned below the plumb line point. The plumb line can be suspended, for example, from the highest available plumb line point. The highest plumb line point is then moved until the plumb bob is aligned with a lower reference point at the other end of the plumb line. The reference point may be in the elevator pit or on a lower, already aligned template. Other templates may be arranged between the highest point and the reference point and may be aligned with the vertical plumb line. The plumb line point may have at least one notch to secure the plumb line. This notch may be a wedge-shaped notch that forms a triangular profile that defines a precise reference mark for the plumb line point. The notch can be formed by an opening in the frame. For example, the frame may include two such wedge-shaped notches on opposite sides of the frame's diameter. Another notch may include a circular opening and an adjacent strip opening leading to the inner edge of the frame. Alternatively, the plumb line point can be designed as a protrusion projecting from the frame. These protrusions can be located at the inner edge of the frame and integrally formed with the frame. Because they do not consume energy, the plumb line can be set for extended periods.

[0020] The mounting point pattern may include at least two separate bracket groups adapted to mount a guide element for an elevator. The guide element may be a rail or linear profile to guide a movable part of the elevator in the vertical direction. The guide element may impede horizontal movement of the movable element. The bracket may transfer horizontal loads from the guide element to the template. The bracket may be a fastener connecting at least one guide element to the building and aligned with the building's fasteners. The bracket may have mounting points for one or more guide elements. The bracket mounting points of the template may be grouped on the template to simulate the screw pattern of the bracket. When the bracket is configured to mount a guide element, the mounting points for the guide element and the screw pattern may be substantially located at opposite ends of the bracket. The bracket may also have multiple screw patterns. For example, the screw patterns may be arranged at opposite ends of the bracket. The bracket may be mounted to the template before the template is aligned.

[0021] Support assemblies can be arranged on opposite sides of the frame. Each support assembly can be used for one support. At least one support in the assemblies can be configured to mount more than one guide element. In particular, one support can be configured to mount three guide elements. This support can be called an Ω-shaped support. Another support can be configured to mount one guide element. This support can be called a Z-shaped support.

[0022] The mounting point pattern may include at least one set of sills configured to install elevator landing door sills. The landing door sill may be a guide element for a landing door. The landing door sill may be positioned at the edge of the elevator opening. The landing door sill may be arranged such that its upper surface coincides with the surface of the finished base plate. Therefore, the landing door sill may project upwards from the surface of the original floor slab. The landing door sill may be installed onto the template before alignment.

[0023] The threshold assembly can be located on a side of the frame different from the bracket mounting point. The bracket assembly can be located on the opposite side of the frame. The threshold assembly can be located on the side of the frame, thus connecting the opposite sides. An additional threshold assembly mounting point can exist for an alternative location for the landing door threshold. The alternative location can be on the opposite side of the frame.

[0024] The frame can be configured to be laid flat on the horizontal surface of the floor slab. Anchors connected to the anchor points can be oriented transversely to the frame. The frame can be positioned on the underside or top side of the floor slab. Specifically, the frame can be positioned on the top side, and the anchors can be oriented downwards and / or outwards from the frame. The flat frame can be easily aligned with the hoistway by moving the frame on a surface perpendicular to the hoistway. This surface can be set using a formwork shell for pouring concrete into the floor slab. The aligned frame can be secured to the formwork shell before pouring concrete to prevent misalignment during pouring.

[0025] The template may include a frame made of steel, particularly a frame made of sheet steel. This frame may be formed as a rectangular frame. Furthermore, the frame may be configured such that connections occur on the upper horizontal sides of the frame.

[0026] The frame can be a single piece, meaning it can be a monolithic component, preferably manufactured before installation in the building. The frame can be cut from sheet metal. Alternatively, the frame can be assembled from multiple parts connected to each other. A one-piece frame can be dimensionally stable. In particular, the angles between the sides of the frame can be precisely cut using a cutting machine. A flat frame provides high resistance to angular deformation while being flexible in planes perpendicular to the frame.

[0027] The formwork may include at least one reinforcing member configured to reinforce the frame while aligning the formwork. The reinforcing member may be temporarily fixed to the frame. The reinforcing member may be removed after the formwork is anchored to the floor slab. The reinforcing members may be arranged diagonally across the frame. The reinforcing members may traverse the shaft. The reinforcing member may be integral with the frame and may be cut off after the formwork is anchored to the floor slab. Alternatively, the reinforcing member may be screwed to the frame and can be reused for another frame after being unscrewed from it. A screw-on reinforcing member can connect at least two mounting points of the formwork. The reinforcing member may be removed before installing the hardware. The reinforcing member may include a lifting point to lift the formwork to its mounting position. The reinforcing member may include a plumb line point for aligning the formwork with the floor slab, thus eliminating the need for a plumb line point on the frame.

[0028] According to a second aspect, an elevator for a building (particularly a building without a structured (RCC) elevator shaft) is disclosed, wherein the elevator hardware is mounted to mounting points of a plurality of aligned templates according to the first aspect. The templates are arranged at the intersection of the elevator shaft and the floor slabs of the building. The frames of the aligned templates are anchored to the floor slabs by an array of anchor points and are arranged to be laterally offset relative to the shaft.

[0029] According to a third aspect, a method for installing an elevator in a building (particularly a building without an elevator shaft without RCC) is disclosed. The method includes: aligning a plurality of templates according to the first aspect such that the frame is laterally offset relative to the elevator shaft, and aligning the templates with the shaft at the intersection of the shaft and the building's floor slab; using an array of anchor points to anchor the aligned templates to the floor slab; and using a pattern of mounting points to install the elevator hardware onto the aligned templates.

[0030] The formwork can be aligned before pouring concrete for the floor slab. During pouring, at least one anchor (which is an anchor connected to at least one of the anchor points) can be cast in place. Compared to drilled anchors, cast-in-place anchors provide greater stability and reduce stress transmitted to the floor slab. Since drilling is unnecessary due to the casting within the anchors, noise, vibration, and dust exposure for construction workers are reduced. Without percussion drilling or hammer drilling, a potential cause of damage to the floor slab is eliminated because the need to crack the hardened concrete structure is eliminated.

[0031] During the installation of the hardware to the mounting points, the hardware can be adjusted into the shaft. The mounting points of the formwork and / or the fixing points of the hardware can be slots to provide limited adjustability. This allows minor misalignments of the aligned formwork to be corrected during concrete pouring and setting. Alternatively or supplementarily, the frame can be adjusted to the anchors before the hardware is installed to the mounting points. If the anchors are cast-in-place bolts and the anchor points are slots, the bolts can be loosened in the anchor points and the frame can be adjusted relative to the shaft. By adjusting the frame, all mounting points are adjusted simultaneously because the mounting points are in fixed positions on the frame. Adjusting the frame saves time.

[0032] The term "floor slab" refers to a structured feature that typically has a constant thickness, can be formed using concrete (and often with steel reinforcement), and can form part of the structure of a building. A floor slab defines the structured feature that defines each floor / story of a building except for the lowest floor (i.e., the floor at the lowest point of the building). The top surface of a floor slab may be called the bottom slab, and the bottom surface may be called the top slab or ceiling.

[0033] The term "elevator recess" refers to an enclosed space formed below the lowest floor (i.e., the floor at the bottom of a building).

[0034] The term "elevator opening" refers to a through hole formed between the top and bottom surfaces of a floor slab.

[0035] The term "horizontal surface" in floor slabs refers to the top or bottom surface of the floor slab.

[0036] The term "shaft" refers to a passageway that runs through elevator openings on each floor slab, extending from the top floor slab of the building to the bottom floor slab.

[0054] Embodiments of the present invention will now be described in detail with reference to the accompanying drawings.

[0055] Figure 1a A partial perspective view of a floor slab 100 of a building according to an embodiment of the present disclosure is shown, depicting an installed formwork 102. The floor slab 100 is a flat plate made of reinforced concrete (RCC). The upper portion of the floor slab is referred to as the floor of the corresponding floor of the building. The lower portion of the floor slab is referred to as the top slab or ceiling of the floor below. The floor slab 100 has an elevator opening 104. The elevator opening 104 extends from the floor slab through the floor slab 100 to the ceiling. The vertical surface of the elevator opening defines the external limits of the elevator shaft 106 for the elevator. Here, the elevator opening 104 is generally square. The shaft 106 consists of a plurality of vertically aligned elevator openings 104 in a plurality of floor slabs 100 on different floors of the building. The shaft 106 is a series of empty spaces for the moving parts of the elevator. The elevator hardware 108 protrudes into the shaft 106.

[0056] In the method presented herein, hardware 108 is mounted to template 102, and template 102 is anchored to floor slab 100. Hardware 108 is connected to template 102 at mounting points 110. Template 102 is connected to floor slab 100 at anchoring points 112. Mounting points 110 are arranged in a predetermined pattern. Anchoring points 112 form an array distributed above template 102. Mounting points 110 and anchoring points 112 are held in fixed relative positions by a rigid frame 114 of template 102. Frame 114 is arranged outside shaft 106. Anchoring points 112 are connected to anchors 116 embedded in floor slab 100.

[0057] Templates designed with cutout sizes to accommodate bracket installation will ensure error-free and robust installation.

[0058] Figure 1b A perspective view of template 102 according to an embodiment of the present disclosure is shown. Template 102 corresponds to the template in FIG1.

[0059] Figure 2a and Figure 2b A perspective view of the mounting point 110 of template 102 according to an embodiment of the present disclosure is shown. Template 102 corresponds to the template in FIG1.

[0060] Figure 2c An anchor point 112 of template 102 according to an embodiment of the present disclosure is shown. Template 102 corresponds to the template in FIG1.

[0061] In one embodiment, anchor 116 has a threaded shank, and anchor point 112 is a hole in frame 114. The shank protrudes from floor slab 100 and passes through the hole. On the opposite side of frame 114, the shank protrudes through a washer, and a nut is tightened onto the washer. The shank can be cast in place, glued into a drilled hole, or wedged into a hole. When anchor 116 is cast in place, formwork 102 is aligned with shaft 106 before pouring concrete for floor slab 100. During pouring, pourable concrete flows around anchor 116 and hardens around anchor 116. Preferably, anchor 116 has an undercut for shape locking in the concrete.

[0062] like Figure 2c As shown, the embedded anchor 116 may alternatively have negative threads, and the threaded bolt 200 may be screwed through the anchor point 112.

[0063] Frame 114 is made of steel plate and is formed as a rectangular frame. Frame 114 is configured such that connections occur on the upper horizontal sides of frame 104.

[0064] In this embodiment, the holes of the anchor points 112 are elongated, thus forming slots. By loosening the connection to the anchor 116, the template 102 can be adjusted within the gaps of the slots. When adjusting the template 102, the connection to the anchor 116 can be tightened again. By adjusting the template 102, the entire pattern of the mounting points 110 can be adjusted at once. The slots reduce the requirement to align the template 102. Only the template 102 needs to be roughly aligned with the shaft 106 within the gaps of the slots. Fine adjustments are achieved using the gaps of the slots.

[0065] In an alternative embodiment, anchor 116 is welded to anchor point 112. Anchor 116 is cast in place during the manufacture of floor slab 100. Here, the formwork 102 is perfectly aligned with the shaft 106 before the concrete is poured.

[0066] In this embodiment, mounting point 110 is a slot. By loosening the connection to hardware 108, hardware 108 can be adjusted within the gap of the slot. When adjusting hardware 108, the connection to the hardware can be tightened again. The slotted mounting point 110 can be used for fine adjustment of hardware 108.

[0067] like Figure 2b As shown, hardware 108 may also have slots for the final adjustment amount.

[0068] In one embodiment, template 102 includes two plumb lines 118. The plumb lines 118 protrude above the edge of the elevator opening. To align the template with the shaft 106 and with other templates on other floors of the building, a plumb line is attached to the plumb lines 118, and a plumb bob is used to orient the plumb line vertically by gravity. Using the plumb line as a reference marker, other templates with plumb lines can be aligned with template 102. Alternatively, a plumb line can be installed along the entire shaft 106 as a reference marker, and the plumb lines 118 can be used to align template 102 with the plumb line.

[0069] In this embodiment, the pattern of mounting points 110 is divided into multiple groups of mounting points 110. Each group corresponds to a specific piece of hardware. These groups are distributed above the template 102.

[0070] In this embodiment, two bracket assemblies 120 at bracket mounting point 110 are arranged on opposite sides of template 102. The bracket assembly 120 is configured to mount brackets 122 for elevator tracks 124. One bracket 122, referred to as an Ω-shaped bracket, is configured to fix three tracks 124. Two of the tracks 124 guide the elevator counterweight along the hoistway 106, and the third track 124 guides one side of the elevator car along the hoistway 106. The other bracket 122, referred to as a Z-shaped bracket, is configured to fix one track 124. The track 124 guides the other side of the car along the hoistway 106.

[0071] In one embodiment, the support frame 122 is installed onto the formwork 102 in the factory before the formwork 102 is transported to the construction site.

[0072] In one embodiment, a threshold assembly 126 of threshold mounting point 110 is arranged along the third side of template 102. Threshold assembly 126 is configured to install a landing door threshold 128 for that floor of the building. The landing door threshold 128 guides the landing door between an open and closed position. The landing door threshold 128 may be pre-installed onto template 102.

[0073] like Figure 2c As shown, the landing threshold 128 can protrude vertically above the template 102. The landing threshold 128 can be height-adjustable to compensate for misalignment of the floor slab 100.

[0074] In this embodiment, the frame 114 is arranged flat on the upper side of the original floor slab 100 and protrudes slightly above the edge of the elevator opening 104. Anchors 116 are oriented downwards into the floor slab 100. This flat shape facilitates the production and transport of the template 102. The template 102 is stable in the horizontal plane to fix the relative positions of the mounting point 110 and the anchor point 112. The template 102 is flexible in the vertical direction to adapt to the surface of the original floor slab 100. When the original floor slab 100 is covered by impact insulation and a scraper, the template 102 will be at least partially covered. Specifically, the landing door sill 128 will be flush with the surface of the base plate arranged on top of the scraper.

[0075] In this embodiment, the template 102 is reinforced by a temporary reinforcing member 130. This reinforcing member 130 increases the rigidity of the frame 114 in the plane of the floor slab 100. During the installation of the template 102, the reinforcing member 130 prevents deformation of the pattern at the mounting points 110. The reinforcing member 130 is removed before further elevator installation.

[0076] While specific language has been used to describe the subject matter, it is not intended to be limiting. It will be apparent to those skilled in the art that various working modifications can be made to the method to achieve the inventive concept taught herein. Examples of embodiments are given in the accompanying drawings and the foregoing description. Those skilled in the art will appreciate that one or more of the described elements can be well combined into a single functional element. Alternatively, certain elements may be separated into multiple functional elements. Elements from one embodiment may be added to another embodiment.
