Description

[0001] A METHOD FOR INSTALLING A PROTECTION DECK OF AN

[0002] ELEVATOR, A METHOD FOR CONSTRUCTING AN ELEVATOR AND AN ARRANGEMENT FOR INSTALLING A PROTECTION DECK OF AN ELEVATOR

[0003] Field of the invention

[0004] The invention relates to installing a protection deck to cover an elevator hoistway.

[0005] Background of the invention

[0006] During construction work of an elevator or a building, lower parts of an elevator hoistway may temporarily need to be protected from objects or water falling into the lower parts of the hoistway. For example, tools or construction material may fall into the hoistway. Persons and elevator components located in the lower parts of the hoistway must be protected from falling objects. For this purpose an overhead protection deck has been used. Such a protection deck typically forms a roof-type structure extending across the hoistway and covering the hoistway such that it blocks objects from falling into the hoistway below it.

[0007] Installing of a protection deck in place usually involves building it at least partially and thereafter hoisting it to its mounting place. The mounting must be done safely and firmly. The protection deck may need to be hoisted later to yet another position, in particular to an even higher position in the hoistway. These steps take time and for making the process quick, the protection deck should be easily mountable and demountable without risking safety. These aspects are important particularly when the elevator solution is a so called jump lift. In a jump lift solution, the upper parts of the building as well as the top part of the elevator hoistway can be constructed at the same time as an elevator moving in the bottom part of the elevator hoistway already serves people on the lower floors of the building under construction. In this kind of cases the protection deck is typically lifted stepwise for enabling stepwise increasing of lifting height of the elevator below the protection deck. Such a solution has been disclosed in document EP3388379A1, for instance.

[0008] A problem of prior protection decks has been that they have not been very quick to position and fix immovably in place. Another problem has been that their mounting has taken space such that door installation has been difficult to do up to the level of the protection deck. A further problem has been that the hoisting arrangements for moving the protection deck have required a lot of free hoistway space above the protection deck and / or required finding a support point from a high location, which have set limitations for how high the protection deck can be positioned in the hoistway.

[0082] Detailed description

[0083] Figures 1-4 illustrate consequent phases of a first embodiment of a method for installing a protection deck 1 to cover an elevator hoistway 2 formed in a building 3. The protection deck 1 is installed temporarily for providing protection below it during construction time of the building 3 and / or an elevator. The building 3 comprises landings 4 and the elevator hoistway 2 has at the front side thereof one or more openings 5 each leading from the hoistway 2 to a landing 4. The method comprises fixing mounting brackets 6,8 to stationary structures 7,9 located beside the hoistway 2. In Figure 1 the brackets 6,8 are illustrated in fixed state. Said stationary structures are here a floor 7 of a landing 4 and a back wall of the hoistway 2. Thus, said fixing comprises fixing a floor bracket 6 to a floor 7 of a landing 4 and a wall bracket 8 to the back wall 9 of the hoistway 2, said back wall 9 being opposite to an opening 5 leading to said landing 4.

[0084] After said fixing of the mounting brackets 6,8, the method comprises hoisting a protection deck frame structure 10 [also later referred to as a "frame structure"] in the hoistway 2 from a position lower than the landing 4 to be beside said landing 4. The frame structure 10 comprises a front end la and a rear end lb. Figure 1 illustrates movement of the frame structure 10 during the hoisting by arrow al. Figure 2 illustrates the frame structure 10 beside said landing 4. The lower position may be the pit of the hoistway 2 [in a case where the frame structure is being mounted first time in the hoistway 2] or alternatively a preceding mounting position [in a case where the frame structure 10 has been mounted already before in a lower position].

[0085] After hoisting of the frame structure 10 to be beside the landing 4, the method comprises mounting the frame structure 10 to extend across the hoistway 2 beside the landing 4, such that the front end la is supported by structures 7 on the front side of the hoistway 2 and the rear end lb is supported by structures 9 on the rear side of the hoistway 2. Figure 3 illustrates said mounting. Said mounting comprises coupling at least one front end coupling member 11 provided at said front end la with said floor bracket 6 fixed to the floor 7 of the landing 4, and coupling at least one rear end coupling member 12 provided at said rear end lb with said wall bracket 8 fixed to the back wall 9 of the hoistway 2. Said floor bracket 6 forms a counterpart for the front end coupling member 11 and said wall bracket forms a counterpart for the rear end coupling member. Figure 4 illustrates the frame structure 10 mounted to extend across the hoistway 2 beside the landing 4 [also referred to as "mounted state"]. When the frame structure 10 is thus mounted, the front end la is supported by floor

[0086] 7 via said floor bracket 6 and the front end coupling member 11, and said rear end lb is supported by the back wall 9 of the hoistway 2 via the wall bracket

[0087] 8 and the rear end coupling member 12.

[0088] The frame structure 10 is preferably such that it comprises plurality of beams bl,b2 fixed to each other. Thus, a rigid structure can be easily achieved. The frame structure 10 can be hoisted in said hoisting while having one or more cover plates 20 mounted on it as it is the case in the illustrated embodiment. In the illustrated embodiment, one or more [additional] cover plates 20 are mounted on the frame structure 10 after it has been mounted.

[0089] The floor bracket 6 and the front end coupling member 11 are pivotably couplable. In said coupling a front end coupling member 11 provided at said front end la with said floor bracket 6 fixed to the floor 7 of the landing 4, they are pivotably coupled, and said mounting comprises after this coupling, lowering L the protection deck frame structure 10 such that it pivots P around a pivot axis x formed between the front end coupling member 11 and the floor bracket 6 fixed to the floor 7 of the landing 4. After said coupling of said front end coupling member 11 and before said lowering L, the protection deck frame structure 10 is suspended in the hoistway 2 beside said landing 4 in an inclined state by the hoisting arrangement 14. In said inclined state the front end la is lower than the rear end lb. The lowering L is illustrated in Figure 3 by arrow L. The pivoting P is illustrated in Figure 3 by arrow P. In said lowering L, the protection deck frame structure 10 pivots P such that the rear end coupling member 12 moves towards the back wall 9 of the hoistway and towards a wall bracket 8 fixed to the back wall 9. In the lowering L of the frame structure 10 the rear end coupling member 12 is moved to be supported by structures on the rear side of the hoistway 2, in particular by the wall bracket 8 fixed to the back wall 9. The pivoting P facilitates good control of the lowering of the frame structure 10 into position to extend across the hoistway 2 beside the landing 4. The movement thereof during said lowering and forces cause are thus in good control. This facilitates that the mounting can be done safely, swiftly and without breaking components, even when in done with relatively small clearances.

[0090] In the preferred embodiment, said front end coupling member 11 and the floor bracket 6, when they are coupled, form a hinge with horizontal pivot axis x.

[0091] Figures 9-10 illustrate preferred details of the front end coupling member 11 and the floor bracket 6 fixed to the floor 7 of the landing 4. The coupling member 11 and the floor bracket 6 are coupled / couplable with a pivot pin p extending through a hole h provided on the front end coupling member 11 and a hole provided on the floor bracket 6. In the coupling, the pivot pin p is secured in place. The pivot pin p can be a pin to be secured by a cotter, or alternatively formed by a bolt to be secured by a nut. The pivotal coupling could be also be implemented in numerous alternative ways, as known in the mechanical field. The coupling member 11 is in the preferred embodiment in particular such that it has a fork end having two fork members having a hole and placeable around a vertical plate of the floor bracket 6 such that the holes of the fork members and a hole of the floor bracket 6 coincide such that a pin p can be placed through the holes in the coupling.

[0092] The floor bracket 6 is in the preferred embodiment, in particular such that two of said front end coupling members 11 can be coupled to it. Coupling by two of said front end coupling members 11 facilitates stability of the frame structure 10, in particular when it is being pivoted. For this purpose, said floor bracket 6 forms a counterpart for two front end coupling members 11 and said mounting comprises coupling two front end coupling members 11 provided at said front end la with said floor bracket 6 fixed to the floor 7 of the landing 4. In the embodiment of Figure 10, this is implemented such that the floor bracket 6 comprises two of said vertical plates each having a hole, and two of said coupling members 11 having a fork end have been provided at said front end la of the deck frame 10 and couplable with the two plates of the floor bracket 6.

[0093] The wall bracket 8 is preferably more specifically such that it comprises a support nest 8a having an upwards open mouth 8a 1, the rear end coupling member 12 having a shape locking portion 12a insertable by lowering it via said mouth 8a 1 into the support nest 8a to rest supported by the support nest 8a. For facilitating later dismounting of the frame structure 10, the shape locking portion 12a is preferably moreover removable from the support nest 8a by raising it. In the lowering L of the frame structure 10 the shape locking portion 12a of the rear end coupling member 12 is inserted into the support nest 8a to rest supported by the support nest 8a.

[0094] Said mouth 8a 1 is within hoistway 2 and particular outside the hoistway wall 9 projection, such that the shape locking portion 12a can be lowered into the interior 8i via said mouth 8a 1 without moving it in front-to-back direction of the hoistway 2 into a cavity of the hoistway wall 9. Thus, lowering of the shape locking portion 12a into the nest is simply doable by pivoting for instance.

[0095] In the preferred embodiment, the wall bracket 8 is fixed against a vertical face of the back wall 9. The face is preferably a concrete face but could also be of some other material. Particularly, the back wall 9 could alternatively be a metal beam hoistway wall, in which case it would be preferably formed by a metal beam framework, which is a known way to produce a hoistway wall. The wall bracket 8 is preferably disposed in particular such that a free space extends on top of the mouth 12a, through which free space the shape locking portion 12a is movable into the interior 8i via said mouth 8a 1, the space being preferably at least 1 meter high, and empty of stationary structures of the building, back wall 9 or structures fixed to it. Thus, lowering of the shape locking portion 12a into the nest is facilitated and simply doable by pivoting for instance. Figures 11-12 illustrate preferred details of the shape locking portion 12a and the wall bracket 8. In these Figures, the shape locking portion 12a is illustrated positioned above said mouth 8a 1 and lowerable into the interior 8i via said mouth 8a 1. Here, the support nest 8a comprises a front wall portion 8b obstructing the shape locking portion 12a, when positioned in the support nest 8a, from moving towards front side of the hoistway 2 out from the nest 8a, and side walls 8c obstructing the shape locking portion 12a when in the support nest 8a from moving towards sides out from the nest 8a. Obstruction of movement of the the shape locking portion 12a from moving front side and / or sides out from the support nest provides that the support nest 8a serves as a locking nest. The wall bracket 8 can comprise a slot 8f extending from hoistway into the interior 8i of the support nest 8a, which slot is open upwards, the slot 8f being suitable for receiving an arm portion 12c of the rear end coupling member 12. Thus, the arm portion 12c can be positioned low relative to the locking portion 12a. This may be advantageous for stability of the structure when the mounting is finished, as well as for maintaining the parts 8 and 12 better visible towards landing 4 during the lowering L. The slot 8f is however not necessary. The illustrated embodiment comprises moreover a bottom 8d for supporting vertically the shape locking portion 12a on top of it in the interior 8i of the nest 8a. The vertical support can be provided alternatively by a ledge structure [not shown] for supporting vertically the shape locking portion 12a on top of it in the interior 8i of the nest 8a, wherein the ledge structure protrudes [from any side] to the vertical projection of the shape locking portion 12a when it has been inserted in the interior 8i of the nest 8a. However, the bottom 8d or the ledge correspondingly is not necessary for the supporting function, or at least the bottom 8d or ledge do not need to provide said function, because the side walls 8c can be also suitable for supporting vertically the shape locking portion 12a, in which case they may define a downwardly narrowing shape for the interior 8i as it is illustrated in Figure 19. Figure 19 shows the bracket 8' and the rear end coupling member 12' with an alternative structure. The side walls 8c are inclined so that they define a downwardly narrowing shape for the interior 8i. Thereby, the shape locking portion 12a will be wedged stationary when inserted into the nest 8a. The structure of Figure 19 can be used in place of the structure shown in Figures 11-12.

[0096] In the preferred embodiment illustrated in Figures 1-4, said hoisting is performed with a hoisting arrangement 14 mounted on the landing 4, in particular fixed to the floor 7 of the landing and / or to a landing wall 41 of the landing 4. Preferably, the hoisting arrangement 14 comprises a hoisting beam structure 15 extending into the hoistway 2 through the opening 5 of the landing 4, and at least one flexible support member 16 hanging in the hoistway 2 supported by the support beam structure 15, the flexible support member 16 being connected or connectable to the protection deck frame structure 10.

[0097] In the preferred embodiment illustrated in Figures 1-4, the floor bracket 6 is fixed in said fixing a distance apart from the edge e between the landing floor 7 and the hoistway 2. This facilitates early installing of doors, because door guide rails can be installed to extend in proximity and / or along the edge e. In the preferred embodiment, the opening 5 has been provided with an openable and closable landing door 13. The landing door 13 is open during the hoisting for allowing said hoisting beam structure 15 to extend into the hoistway 2 through the opening 5. These preferred further features are visible in Figure 15. The distance is preferably more than 10 cm, more preferably more than 20 cm.

[0098] In the preferred embodiment illustrated in Figures 1-4, in said hoisting, the frame structure 10 is moved upwards in the hoistway 2 in a non-horizontal state, more specifically in an inclined state. In said non-horizontal state the front end la is lower than the rear end lb, although possibly alternatively vice versa. Later, when the frame structure 10 is in its mounted state, the front end la and the rear end lb are at the same level or at least vertically closer to each other than in said non-horizontal state. Inclined state facilitates swift hoisting due to reduced risk of contacting other components. In said non- horizontal state one or more beams bl,b2 of the frame structure 10 are inclined to point upwards towards the back side of the hoistway 2 at an angle relative to horizontal, which is preferably between 20 and 60.

[0099] Figures 16 and 17 illustrate preferred further features of said hoisting, and the arrangement Al. Figure illustrates the frame structure 10 from a side, and Figure 17 from above, while it is being hoisted. As illustrated, in said hoisting, the frame structure 10 is preferably suspended from plurality of lifting points L1-L4, distributed such that they are corner points of a polygon shape when viewed from above, such as a triangle or quadrangle. The flexible support member 16 is connected to the frame structure 10 at said lifting points L1-L4 during the hoisting. The cover plates 20 are illustrated in Figure 17 by broken line for revealing beam structures below, and also because presence of said cover plates 20 already during the hoisting is not necessary. Figures 16 and 17 also illustrate the preferred aspect that movement of the frame structure 10 in said hoisting is guided by at least one guide device 18 mounted on the frame structure 10 movable along a vertically oriented guide rail 17 mounted in the hoistway 2. The guide rail 17 is preferably a guide rail to be utilized for guiding an elevator car C at a later stage of the method. The flexible support member 16 is preferably a chain or cable having a main hoisting member portion 16a and different length hoisting member portions 16b-16e shorter than said main hoisting member portion 16a, which different length hoisting member portions 16b- 16e are connected to the lifting points L1-L4, such that the protection deck frame structure 10 is suspended in an inclined state. Preferred details of the flexible support member 16 and connection thereof to the frame structure 10 are also shown in Figure 13.

[0100] The guide device 18 has one or more guide members 18a for contacting a guide rail 17, which one or more guide members 18a are preferably mounted on the frame structure 10 pivotably. Thus, the angular position of the frame structure 10 has freedom to change during the process, which reduces forces, makes hoisting smooth, reduces likelihood of components braking, and allows a substantially inclined state, as well as allows assembly of the frame structure 10 in horizontal position. The guide device 18 comprising said one or more guide members 18a is then mounted on the frame structure 10 in particular via a pivot joint j, in particular such that the protection deck frame structure 10 can pivot around a pivot axis y to different angular positions relative to the guide device 18 and its guide members 18a and the guide rail 17. The guide device 18 is preferably mounted on the frame structure 10 pivotably more than 10 degrees, more preferably at least 20 degrees, most preferably at least 30 degrees or in general preferably at least an angle corresponding to an inclination angle desired for the frame structure 10 during said hoisting. The pivot axis y of the pivot joint j is preferably horizontal and oriented orthogonal to the back to front direction of the hoistway 2. The guide device 18 is preferably separable from the guide rail 17. This can be implemented in various ways, such as sophistically by arranging it to be slidable, or pivotable away from proximity of the guide rail 17 [in Figure 17 in left-right direction towards the center of the frame structure 10] or possibly disassemblable by opening releasable fixing means. This separating facilitates that the frame structure 10 can be moved more freely outside the hoisting phase, e.g. for enabling position-related adaptability of the frame structure 10 to be easily coupled. After the hoisting, for facilitating the coupling and freedom of movement during the lowering L illustrated in Figures 3 or 7, the guide device 18 is preferably separated from the guide rail 17 in particular such that it does not obstruct horizontal movement of the frame structure 10 in front-to-back - direction of the hoistway 2.

[0101] In general, the guide members 18a are preferably slider members for sliding along a guide rail 17 [as illustrated], or alternatively guide rollers for rolling along a guide rail 17.

[0102] In Figure 18, preferred, however not necessary, details have been illustrated. In an embodiment according to Figure 18, the guide device 18 comprises a horizontally extendable and retractable actuator 108 supporting the one or more guide members 18a. Thereby, the aforementioned separating can be performed by the actuator 108. Also, hereby the horizontal position of the frame structure 10 can be made adjustable using the actuators 108. Preferably, there are on opposite sides of the frame structure 10 two guide devices 18 each provided with an actuator 108. These two actuators 108 are then preferably extendable and retractable horizontally along the vertical plane defined by two guide rails 17 positioned to extend vertically on opposite sides of the frame structure 10. Then, by actuation of the actuators 108, the distance position where the frame structure 10 will be guided by the guide rails in said hoisting, can be adjusted along the guide rail plane. In general, the actuator 108 can be a screw jack, or hydraulic jack, or pneumatic jack, for example. For producing movement, the actuator 108 then comprises a hydraulic cylinder or pneumatic cylinder or screwing means, which have been schematically shown by part 1083 in Figure 18. The actuator 108 can be provided with a cylinder and a shaft 1082 movable back and forth in the cylinder [e.g. moved by screwing or hydraulically or pneumatically] and supporting the one or more guide members 18a. If pivotability is desired for the guide members 18a, the actuator can be connected to the more guide members 18a via a pivot joint j. In general, the actuator 108 is not necessary.

[0103] Figures 2 and 3 illustrate arrangements Al and A2 for installing a protection deck 1 to cover an elevator hoistway 2 formed in a building 3. These arrangements Al and A2 are realized at different phases of the method described above. As described, the building 3 comprises landings 4 and the elevator hoistway 2 comprises at the front side thereof an opening 5 leading to a landing 4, the arrangement Al, A2 comprising a protection deck frame structure 10, in the hoistway 2 wherein the frame structure 1 comprises a front end la and a rear end lb. The arrangement Al, A2 moreover comprises a hoisting arrangement 14 for hoisting the protection deck frame structure 10; and mounting brackets 6,8 fixed to stationary structures 7,9 beside the hoistway 2, comprising a floor bracket 6 fixed to a floor 7 of a landing 4 and a wall bracket 8 fixed to the back wall 9 of the hoistway 2, said back wall 9 being opposite to an opening 9 leading to said landing 4.

The position of the protection deck 1 can be controlled manually and / or with said hoisting arrangement 14 such that the front end coupling member 11 and the floor bracket 6 can be coupled.

[0107] In the arrangement A2 of Figure 3 the front end coupling member 11 is coupled with the floor bracket 6, in particular pivotally.

In the arrangement A1,A2, said front end coupling member 11 and the floor bracket 6, when they are coupled, in particular form a hinge with horizontal pivot axis x. The pivotal coupling facilitates good control of the lowering of the frame structure 10 into position to extend across the hoistway 2 beside the landing 4. In particular, the movement of the frame structure 10 during said lowering L and forces caused are manageable and in good control. This facilitates that the mounting can be done safely, swiftly and without breaking components, even when in done with relatively small clearances.

[0108] The arrangement Al, A2 moreover comprises a rear end coupling member 12 provided at said rear end lb, which rear end coupling member 12 is couplable with said wall bracket 8 fixed to the back wall 9 of the hoistway 2. Said wall bracket 8 forms a counterpart for the rear end coupling member 12.

[0109] The arrangement A1,A2 is preferably furthermore as described in context of the method referring to Figures 2 and 3, respectively. Accordingly, preferably the hoisting arrangement 14 is mounted on the landing 4, in particular fixed to the floor 7 of the landing and / or to a wall of the landing 4.

[0110] In the arrangement A2, the floor bracket 6 and said front end coupling member 11 are pivotably coupled, the protection deck frame structure 10 being lowerable such that it pivots P around a pivot axis x formed between said front end coupling member 11 and the floor bracket 6 fixed to the floor 7 of the landing 4.

[0111] The protection deck frame structure 10 is lowerable such that the rear end coupling member 12 is moved to be supported by the wall bracket 8 fixed to the back wall 9. The protection deck frame structure 10 is in particular lowerable to pivot around the pivot axis x such that the rear end coupling member 12 moves towards the back wall 9 of the hoistway and towards a wall bracket 8 fixed to the back wall 9.

[0112] The wall bracket 8 comprises a support nest 8a, having an upwards open mouth 8a 1, the rear end coupling member 12 having a shape locking portion 12a insertable from above by lowering it via said mouth 8a 1 into the interior 8i of the support nest 8a to rest supported by the support nest 8a. Said mouth 8a 1 is within hoistway 2 and particular outside the hoistway wall 9 projection, such that the shape locking portion 12a can be lowered into the interior 8i via said mouth 8a 1 without moving it in front-to-back direction of the hoistway into a cavity of the hoistway wall 9.

[0113] Figures 5-8 illustrate an alternative embodiment for the method for installing a protection deck 1', where the wall bracket 8 is omitted. In this embodiment, the wall bracket 8 is not necessary and it is omitted. Figures 6 and 7 illustrate an alternative embodiments of an arrangements Al' and A2' for installing a protection deck 1' to cover an elevator hoistway 2 formed in a building 3. These arrangements Al' and A2' are realized at different phases of the method of Figures 5-8. This embodiment is otherwise similar to that of Figures 1-4, and 9, 10, 13, 15-18, but the rear end lb is supported by structures 9 on the rear side of the hoistway 2 in a different manner.

The coupling member 11 and / or 12 can be separable from the frame structure 10 for temporarily making the overall structure smaller, for instance, which may facilitate hoisting in a tight hoistway 2. Either one, or both, of the coupling members 11,12 could however alternatively be a fixed part of the frame structure 10.

[0117] In the illustrated embodiments, the arrangement Al, A2 comprises one or more cover plates 20 mounted on the frame structure 10.
