Description

A CONSTRUCTION ELEVATOR ARRANGEMENT AND METHOD

FIELD OF THE INVENTION

The invention relates to a construction elevator arrangement and a method for constructing an elevator. A construction elevator is used in the construction stage of a building.

BACKGROUND OF THE INVENTION

Conventionally, elevators have been built from components into a prefabricated hoistway or a hoistway is fabricated concurrently with the other parts of the elevator. A drawback has been that all elevator installation work taking place at the construction site consumes time and complicates logistics of the construction site. A drawback has also been that accurate positioning of components has required lots of adjustment at the site. Also, modular elevator solutions have been used, where an elevator is built from several modules.

In the construction industry, a construction method is becoming common whereby high buildings are built very quickly from modules prefabricated in a factory, about the size of a sea container. With the quick completion of this type of building, the challenge for the elevator supplier is that with the traditional installation method, the elevator installation time becomes a bottleneck.

One known technique to improve construction process efficiency is a construction-time use CTU elevator with a temporary machine room that can be moved, in other words jumped, upwards as construction progresses. The CTU elevator, such as a jump elevator, enables a faster and safer construction process, earlier closing of the facade, reduced down-time, and safer transportation in all weather conditions. The construction-time elevator enables that construction of the elevator hoistway and elevator installations may continue at higher floors while the elevator is already operating in the same elevator hoistway at the lower floors. In higher buildings, such as those over 10 floors, the builder increasingly wants to have the elevator operational during construction, even before the whole building is finished. In these cases, jump elevators are the most widely known. In a modular elevator, typically the temporary machine room with a motor and its control components are installed in a top module, which is prior known to be the last to be installed in the building, and then the final installation and commissioning of the elevator can begin. If the customer requires the elevator to be used earlier, for example in a semi-finished building, a challenge is that the benefits of modular pre-installation are then lost because the top components of the elevator cannot be installed in advance.

Documents EP 3 747 820 Al and NL 2 002 869 C2 disclose prior art elevators constructed of prefabricated hoistway modules piled on top of each other.

SUMMARY OF THE INVENTION

An object of the invention is to introduce a novel construction elevator arrangement and a novel method for constructing an elevator. An object is to introduce a solution by which one or more of the above defined problems of prior art and/or drawbacks discussed or implied elsewhere in the description can be solved. An object is particularly to provide a solution that enables a jump-type elevator in a modular elevator and thus all the advantages for which the jump is known, particularly a very quick jump time.

The construction elevator arrangement is defined in claim 1.

The method for constructing an elevator is defined in claim 12.

The novel construction elevator arrangement reduces the time required for each jump.

There is no need to demount and mount separately elevator equipment such as the hoisting machinery, the electric cabinet, and rope suspenders with hoisting ropes during the jump of the construction elevator. Said elevator equipment may be moved upwards as one package or unit during the jump inside elevator hoistway modules, which may be mounted in place above a functional construction time elevator.

The hoisting machinery, the hoisting ropes, the rope suspenders, and the electric cabinet may form a reusable combination of elevator equipment. The reusable combination of elevator equipment may be removed from an elevator shaft when the building has been completed and the construction elevator is changed to a permanent elevator. The reusable construction elevator unit may then be used in another building to be constructed.

The elevator may be pre-installed in a separate metal mounting frame which may be called hoistway frame. This hoistway frame may be transported and hoisted into the building to be erected in sections, in other words, in modules, thus reducing the installation time spent from several weeks to a few days.

DETAILED DESCRIPTION

Figure 1 shows a construction elevator arrangement with a plurality of prefabricated hoistway modules A, B to be piled on each other. Each hoistway module A, B borders a hoistway space S into which the whole elevator car 1 or at least the upper or lower end thereof can be fitted to move.

In the assembled state, said plurality of prefabricated hoistway modules

A, B are piled on top of each other as illustrated in Figures 4 and 5 in a building, such that the hoistway spaces S of the prefabricated hoistway modules A, B are vertically aligned forming a continuous vertically elongated hoistway H where the elevator car 1 is arranged vertically movable.

Each said prefabricated hoistway module A, B comprises a tubular frame 4 around the hoistway space S, which tubular frame 4 forms the bearing structure of the hoistway module A, B in question. The tubularity of the frame 4 provides that it surrounds laterally the hoistway space S of the hoistway module A,

B. Tubular structure is advantageous since it increases rigidity and integrality of the individual elevator modules and rigidity and integrality of the resulting pile of hoistway modules A, B.

The elevator car 1 is arranged to be vertically movable in the hoistway H along two guide rail lines for guiding the elevator car 1. Each said prefabricated hoistway module A, B comprises guide rail sections 8 of the guide rail lines for guiding the elevator car 1. Each said guide rail section 8 is suitable for forming a section of a longer guide rail line for guiding the car 1. Each said guide rail section 8 (also referred to as a car guide rail section) is fixed on the tubular frame 4 with at least one fixing bracket 10. The car guide rail sections 8 of the prefabricated hoistway modules A, B have been positioned in the prefabricated modules such that when the hoistway modules A, B are piled on top of each other, the guide rail sections 8 of the modules A, B become vertically aligned forming one or more (in the examples two) continuous vertical car guide rail lines for guiding the elevator car 1.

The construction elevator arrangement comprises a counterweight 2, wherein the whole counterweight 2 or at least an upper or lower end thereof can be fitted to move into the hoistway space S of each hoistway module A, B. The hoistway space S is large enough to envelope the whole elevator car 1 or at least an upper or lower end thereof. When arranging the elevator car 1 to be vertically movable in the hoistway H, also the counterweight 2 is arranged to be vertically movable in the hoistway H, in particular along two guide rail lines for guiding the counterweight.

Each said prefabricated hoistway module A, B comprises guide rail sections 9 of two guide rail lines for guiding the counterweight 2. Each said guide rail section 9 is suitable for forming a section of a longer guide rail line for guiding the counterweight 2. Each said guide rail section 9 (also referred to as a counterweight guide rail section) is fixed on the tubular frame 4 with at least one fixing bracket 10. The counterweight guide rail sections 9 of the prefabricated hoistway modules A, B have been positioned in the prefabricated modules such that when the hoistway modules A, B are piled on top of each other, the guide rail sections 9 of the modules become vertically aligned forming one or more (in the examples two) continuous vertical guide rail lines for guiding the counterweight 2. The same fixing bracket 10 can be used for fixing a guide rail section 8 of the elevator car 1 and a guide rail section 9 of the counterweight 2.

The plurality of prefabricated hoistway modules A, B comprise a prefabricated pit module A and prefabricated intermediate modules B into and through which the whole elevator car 1 can be fitted to move. The pit module A is first placed in a desired installation location of the elevator to be constructed. This location can be inside a building under construction, inside an existing building or beside the outer side face of a building under construction, inside an existing building, for instance. After this, the prefabricated intermediate modules B are piled on top of the pit module A one by one or in groups of intermediate modules B, such that the tubular frame 4 of each prefabricated module A, B carries the weight of the tubular frames 4 of all the prefabricated intermediate modules B piled on top of it.

The prefabricated intermediate hoistway module B comprises a doorway 5 leading away from the hoistway space S of the module in question, and hoistway door 6 for covering in an openable manner at least partially the hoistway doorway 5. Since the hoistway door 6 is comprised in the prefabricated intermediate module B, the most laborious installation work thereof can be done already at the factory where the module is fabricated. Thus, no time-consuming work needs to be done at the installation site, and the elevator can be installed swiftly and with small amount of disturbance to other operations at the construction site.

In the illustrated embodiment, the door 6 is a sliding door mounted on one or more door guide rails 7 mounted on the frame 4 of the prefabricated intermediate hoistway module B. During the piling, the door 6 is locked immovable relative to the frame 4 of the prefabricated intermediate hoistway module B.

The prefabricated pit module A comprises guide rail sections 8 of two guide rail lines for guiding the elevator car 1 and guide rail sections 9 of two guide rail lines for guiding the counterweight 2. The prefabricated pit module A preferably also comprises a doorway leading away from the hoistway space S of the module in question, and hoistway door for covering in an openable manner at least partially the hoistway doorway, although these are not illustrated in Figure 8.

The elevator car 1 and the counterweight 2 are shown inside the hoistway space S of the prefabricated pit module A, which state is preferably when the pit module is hoisted inside the shaft. The prefabricated pit module A comprises buffers 20, 21, including a buffer 20 for stopping descent of the elevator car 1 and a buffer 21 for stopping descent of a counterweight 2.

In the embodiment of Figure 1, the preferably tubular frame 4 of each said prefabricated module A, B is a beam frame 4. The beam frame 4 comprises horizontal beams 4a, vertical beams 4b and diagonal beams 4c rigidly connected together. Said beams include four vertical corner beams 4b, which are connected by horizontal beams 4a, and plurality of diagonal beams 4c extending at an inclined angle in a space bordered by two vertical beams 4b and two horizontal beams 4a. The opposite ends of each diagonal beam 4c are attached, preferably by welding, to a vertical beam 4b and a horizontal beam 4a. Said four vertical corner beams are connected by horizontal beams such that a rectangular cuboid structure is formed. Generally, the beams 4a, 4b, 4c are preferably tubular metal beams. Thus, the beam frame 4 is rigid and light whereby large modules can be formed, transported, and lifted into place. Light weight reduces forces to be beared in piling, whereby a high pile of modules is possible. Generally, the beams 4a, 4b, 4c preferably have one or more planar side faces, such as four planar side faces as illustrated, whereby fixing elevator components to them is facilitated.

In order to form a uniform pile of modules, preferably the prefabricated elevator modules A, B are fixedly attached to each other using bolts or pins or similar fastening methods.

In Figure 1, a jump module C is arranged inside the uppermost prefabricated intermediate module B. In the pre-assembly phase, all the components of the upper part of the elevator are attached to this separate jump module C, which is attached to the hoistway module B that is uppermost in the first phase of the elevator operation. The jump module C is a kind of submodule or module within a module.

This allows the elevator to be roped and deployed in the first phase of the elevator operation at the height at which the jump module C inside the intermediate module B is hoisted and mounted into position. The way the jump module C is mounted to the intermediate modules B is generic, i.e. it can be attached to any intermediate module. It is attached by bolting at the same points in the module frame structure where there is an interface for guide rail fixing brackets.

The components of the top of the elevator are directly attached to the separate jump module C whose position in the hoistway can be changed as the building progresses. This will allow the elevator to serve the lower floors even before the building is completed up to the top.

The modules A, B and C are manufactured and preassembled off site in workshop before delivery to the construction site. The modules are then delivered to the site, for example by conventional truck transport, and unloaded so that they can be hoisted into the elevator shaft, for example by a site crane.

Figure 2 illustrates in a top view preferred details of the the jump module C inside the intermediate module B, and Figure 6 illustrates preferred details of said jump module C to be mounted inside the frame 4 of the prefabricated intermediate module B, and adapted to be jumped vertically inside intermediate modules B mounted on top of each other once the construction work of the building has progressed.

The prefabricated jump module C illustrated in Figures 2 and 6 comprises a jump frame 14 which is adapted to be mounted inside the frame 4 of the intermediate module B and preferably formed as a beam frame 14. The jump module C is arranged vertically movably/jumpable inside the intermediate modules B piled on top of each other. The frame 4 of the intermediate module B is provided with first inner horizontal dimensions defining the inner horizontal dimensions of the hoistway H. The jump frame 14 is provided with second outer horizontal dimensions defining the outer horizontal dimensions of the jump module C. The jump frame 14 is provided with smaller second outer horizontal dimensions than the first inner horizontal dimensions of the frame 4 of intermediate module B.

The jump frame 14 may also be called an inner movable auxiliary frame 14. The frame 4 of the intermediate module B may also be called a hoistway frame 4. The jump frame 14 is a kind of subframe or an inner frame within an outer frame.

Similarly to the frame 4, the jump frame 14 preferably comprises second horizontal beams 14a, second vertical beams 14b and second diagonal beams 14c rigidly connected together. Said second beams include four second vertical corner beams 14b, which are connected by second horizontal beams 14a, and plurality of second diagonal beams 14c extending at an inclined angle in a space bordered by two second vertical beams 14b and two second horizontal beams 14a. The opposite ends of each second diagonal beam 14c are attached, preferably by welding, to a second vertical beam 14b and a second horizontal beam 14a. Said four second vertical corner beams are connected by second horizontal beams such that a rectangular cuboid structure is formed. Generally, the second beams 14a, 14b, 14c are preferably tubular metal beams. Thus, the second beam frame 14 is rigid and light.

The jump module C comprises pre-assembled on the jump frame 14 a hoisting machinery 12 for driving a hoisting roping 3 (illustrated in broken line ] and an electric cabinet 13. The machinery 12 comprises a drive and motor 15 and a drive wheel 16. The motor is preferably an electric motor. Preferably the motor and the drive wheel are coaxial. The machinery 12 and the electric cabinet 13 are mounted inside the jump frame 14 and attached to the second beams of the jump frame 14. The electric cabinet 13 comprises the control equipment of the construction elevator and the electric power supply to the drive of the motor 15.

The prefabricated jump module C comprises pre-assembled to the jump frame 14 one or more rope suspenders 11 (rope fixing brackets) on which an end of a hoisting roping 3 can be fixed inside the jump module C. One or more of said rope suspenders are preferably fixed on a horizontal beam of the jump frame 14. On each of the rope suspenders 11, an end of a hoisting roping 3 can be fixed.

Figure 3 illustrates preferred details of a passage of the roping 3 and a suspension of the elevator car 1 and the counterweight 2. The hoisting ropes 3 are preferably wound on cable drums (not shown in Figures) so that an additional length of the hoisting ropes may be unwound from each cable drum during the jump of the construction elevator.

Figure 4 shows a situation where construction has progressed and the floors serving the elevator can be extended upwards. More hoistway modules B are hoisted into place above each other and above the elevator already in use.

Figure 5 shows a situation where the jump module C is detached from the current intermediate module B and jumped, in other words, hoisted upwards inside the upper intermediate modules B into an upper position within that intermediate module B which is currently at the top of the pile formed of the hoistway modules A, B. In the intermediate module B from which the jump module C has been removed, the final components (missing components) are installed for construction elevator operation, preferably the jump module C is replaced by guide rail sections. Preferably the jump module C is replaced by guide rail sections for forming one or more continuous vertical car guide rail lines 8 for guiding the elevator car 1 and/or one or more continuous vertical counterweight guide rail lines 9 for guiding the counterweight 2. The number of these jump activities illustrated by Figures 4 and 5 can be as many as necessary, depending on the needs and/or requirements of the customer.

Figure 7 is an example flow diagram of a method that can be implemented in the construction of the elevator arrangement described in Figures 1-6.

A plurality of hoistway modules A, B are manufactured and preassembled off site in workshop and delivered to the construction site in step a. The plurality of hoistway modules comprises a pit module A and a plurality of intermediate modules B.

In step b a plurality of intermediate modules B is piled on each other and in step c the pit module A with the car 1 and the counterweight 2 are piled below the intermediate modules B, as shown also in Figure 1.

In step d a prefabricated jump module C within an intermediate module B is provided and piled on top of the pile of hoistway modules A, B as shown in Figure 1.

In step e the CTU elevator is roped to suspend the car 1 and the counterweight 2 as shown for example in Figure 3. Thereafter the CTU elevator is deployed in the first phase of the elevator operation at the height at which the jump module C inside the intermediate module B is mounted into position.

In step f more intermediate modules B are piled on top of each other and above the elevator in use, as shown in Figure 4.

In step g the jump module C is jumped up vertically inside intermediate modules B mounted on top of each other once the construction work of the building has progressed, and the jump module C is mounted inside an upper intermediate module, preferably into position within that intermediate module B which is currently at the top of the pile formed of the hoistway modules, as shown in Figure 5. During the jump of the elevator additional length of the hoisting roping is provided. In step h the CTU elevator is deployed in the second/next phase of the elevator operation at the height at which the jump module C inside the intermediate module B is mounted.

After step h the installation may be continued by repeating the method steps f, g, and h until the building has reached its final height.

Step i comprises finalizing the construction of the elevator for operational use after the construction time use.

Said finalizing may comprise moving the elevator components of the upper part of the elevator from the jump frame 14 of the jump module C to the uppermost hoistway module B. Said finalizing may comprise replacing the jump module frame 14 with fixing brackets and guide rail sections to form one or more continuous vertical car guide rail lines for guiding the elevator car 1 and/or to form one or more continuous vertical counterweight guide rail lines for guiding the counterweight 2. Said finalizing may comprise changing the construction time use machinery 12 or parts of said CTU machinery to a final operational machinery or parts of said final operational machinery. Said finalizing may comprise changing a CTU roping to a final operational roping. Said finalizing may comprise demounting the rope suspenders 11 from the jump frame 14 and mounting them on a hoistway module frame 4. Said finalizing may comprise demounting the electric cabinet 13 from the jump frame 14 and mounting it on a hoistway module frame 4. Said finalizing preferably comprises removing the jump frame 14 from inside the pile of the hoistway modules A, B. Said finalizing may comprise removing the jump frame 14 from inside the pile of the hoistway modules A, B without demounting the construction time use elevator equipment from inside the jump frame 14.

Said finalizing may comprise mounting the hoisting motor 15 on the car guide rail section 8. Thus, the weight of the hoisting machine 15, as well as the load exerted by the roping 3 passing around the drive wheel 16, is carried by the guide rail section 8, and transmittable by the guide rail section to the guide rail sections below it at least partly so that the complete weight of the of the hoisting machine 15, as well as the load exerted by the roping 3 passing around the drive wheel 16. The load exerted by the roping 3 passing around the drive wheel 16 here is formed partially by weight of the roping 3 and partially by the elevator units, such as the car 1 and the counterweight 2 suspended by the roping.

In the application, several details have been presented as preferred. This means that they are preferred, however they are not to be understood as necessary, because it may be that the arrangement can be implemented also without them.

It is to be understood that the above description and the accompanying figures are only intended to illustrate the present invention. It will be obvious to a person skilled in the art that the invention can be varied and modified without departing from the scope of the invention.
