Description

Technical Field

[0001] The present invention relates to an elevator climbing installation system and method, and in particular, to using a permanent elevator during temporary installation, lifting the permanent elevator in an elevator shaft by climbing according to the progress of the building construction, shortening the construction process, and enabling the permanent elevator to operate earlier. The present invention relates to an elevator climbing installation system and method therefor.

Background Art

[0002] In conventional construction work, it was common to use temporary elevators for transporting construction workers, construction materials, and equipment. In that case, after disassembling the temporary elevator and removing it from the construction site, a switchover work to the permanent elevator was carried out. This switchover work required a construction period of more than three months for the construction of super high-rise buildings due to work such as installing elevator rails and mechanical equipment.

[0003] If the permanent elevator can be used temporarily before the completion of the building construction, the process can be shortened and the permanent construction can be put into operation earlier. As one of such methods, a method of climbing the permanent elevator according to the progress of the building construction has been proposed. Since all of these methods use a tower crane or the like during climbing, the tower crane cannot be used for other construction work during climbing.

[0004] Patent Document 1 discloses a method of temporarily using a permanent elevator that can be used temporarily during building construction and has high assembly accuracy and construction safety. Here, the unit shafts of the permanent elevator divided into one or several floors parallel to the building construction are stacked and installed for each several floors, the car and balancer are hoisted in, the lifting machine unit is lifted and used for hoisting materials and the like as a temporary elevator, the unit shafts are increased as the building construction progresses, the machine unit is replaced to extend the lifting height, and after the completion of the building construction, the lifting machine unit is installed in the permanent position and used as a permanent elevator.

[0005] Patent Document 2 discloses a construction elevator that allows for the provision of a sufficiently large temporary machine room, while also improving work efficiency and shortening the construction period. In this invention, the intermediate floors of the hoistway are partitioned with temporary floors and ceilings, and the landings on those floors are enclosed with partition walls to form a temporary machine room. Equipment such as hoisting machines and control panels are installed in this temporary machine room to provide a construction elevator that serves the lower floors. In this invention, the location of the temporary machine room is set so that the hoistway-side tail cord suspension fittings are in a position that takes into account the hoisting path during the permanent installation, thereby allowing the tail cord and suspension fittings to be shared with the permanent installation.

[0006] [Patent Document 1] Japanese Patent Application Publication No. 08-143245 [Patent Document 2] Japanese Patent Application Publication No. 05-238660 [Overview of the Initiative] [Problems that the invention aims to solve]

[0007] As mentioned above, the method of having the permanent elevator climb during the temporary installation has the problem that the tower crane cannot be used for other construction work while the climbing is in progress.

[0008] The purpose of this invention is to solve the aforementioned problems and to provide an elevator climbing installation system and method that allows for the climbing of a permanent elevator during temporary installation without relying on a tower crane, thereby reducing the amount of work required for a tower crane and easily ensuring safety. [Means for solving the problem]

[0009] To achieve the above objective, the elevator climbing installation system according to the present invention comprises a machine room unit comprising the machine room equipment of the building's elevator, a permanent elevator suspended from the machine room unit, and a lifting unit that is lifted to a predetermined position in the hoistway by a lifting machine and causes the machine room unit and the permanent elevator to climb by a hoisting device, wherein the climbed lifting unit and machine room unit are erected and supported on predetermined support beams of the building by a freely extendable and retractable beam.

[0010] With the above configuration, for example, the machine room unit and the permanent elevator, which have been lifted to a predetermined position in the hoistway by a lifting machine such as a tower crane, are climbed by a hoisting device, such as an electric chain hoist, instead of the lifting machine. This eliminates reliance on lifting machines such as tower cranes, and reduces the workload of the tower crane.

[0011] Furthermore, it is preferable that the support beams are connected to the expansion beams via bracing members, and that the expansion beams are fixed to the bracing members with pin bolts. This allows the expansion beams to be erected and supported on the building's support beams within the elevator shaft, while easily ensuring safety, and enabling the permanent elevator to climb.

[0012] Furthermore, it is preferable that the lifting unit and the machine room unit are suspended within the elevator shaft with the telescopic beam housed in the sheath pipe, and that the telescopic beam is pulled out from the sheath pipe and erected and supported on a designated support beam of the building. This allows the telescopic beam to be extended and retracted from the sheath pipe during the elevator's climbing installation, thereby erecting and supporting it on a designated support beam of the building.

[0013] Furthermore, it is preferable that the position of the telescopic beam, when stored in the sheath pipe, is fixed by inserting a fixing pin into the insertion opening and integrating it with the sheath pipe. In this way, by fixing the telescopic beam to the sheath pipe, safety can be easily ensured while the elevator can be rapidly moved upwards.

[0014] Furthermore, it is preferable that the machine room unit is climbed to a predetermined position by an electric chain hoist built into the lifting unit. This makes it easy to ensure safety during the elevator's climbing installation while allowing the elevator to be quickly climbed.

[0015] Furthermore, it is preferable that the lifting unit and the machine room unit are lifted together at a low speed by an electric chain hoist. By having each unit climb at a predetermined distance apart in this way, the elevator can be quickly climbed while easily ensuring safety during the elevator's climbing installation.

[0016] Furthermore, it is preferable that the machine room unit is installed two floors or less from the lifting unit, and the permanent elevator is installed four floors or less from the lifting unit. By installing each unit at a predetermined distance apart in this way, the elevator can be quickly installed while easily ensuring safety during the elevator's climbing installation.

[0017] Furthermore, with the above configuration, the elevator climbing installation method preferably comprises the steps of: installing the lifting unit on the Nth floor, installing the machine room unit on the N-2nd floor, and installing the permanent elevator car on the N-4th floor; constructing the walls of the elevator shaft above the Nth floor and laying temporary decks on each floor within the elevator shaft; erecting elevator guide rails up to the N+7th floor using the upper work platform of the lifting unit and the decks on each floor as working scaffolding; temporarily removing the temporary decks below the N+6th floor in preparation for climbing; lifting the lifting unit with a lifting machine such as a tower crane and installing it on the N+6th floor; lifting the machine room unit and the permanent elevator together with an electric chain hoist and climbing them; and performing the installation work of each unit and the elevator. This makes it possible to quickly climb the elevator while easily ensuring safety. [Effects of the Invention]

[0018] As described above, according to the elevator climbing installation system and method according to the present invention, in the method of climbing the permanent elevator during temporary installation, it is possible to provide an elevator climbing installation system and method that reduce the amount of tower crane work without depending on the tower crane and climb the elevator while easily ensuring safety.

Embodiments for Carrying Out the Invention

[0020] (Unit Configuration of the Climbing Installation System) Hereinafter, an embodiment of the elevator climbing installation system 1 according to the present invention will be described in detail with reference to the drawings. FIG. 1 shows an explanatory diagram of one embodiment regarding the unit configuration of the elevator climbing installation system 1. The unit of the elevator climbing installation system 1 is composed of a hoisting unit 2, a machine room unit 3, and a permanent elevator 4. When the construction of the building progresses and the construction of the lower part of the elevator shaft 6 is completed, the permanent elevator 4 is installed in the elevator shaft 6, and the machine room unit 3 in which the machine room equipment of the permanent elevator 4 is unitized is installed above it. The permanent elevator 4 suspended from this machine room unit 3 and the hoisting unit 2 that is hoisted to a predetermined position in the hoistway by a hoisting machine and climbs the machine room unit 3 and the permanent elevator 4 by a winding device are provided. In this way, the hoisting unit 2 and the machine room unit 3 are hoisted integrally at a low speed. On the upper floor of this machine room unit 3, an upper work floor 16 and an upper work floor 16兼hoisting unit 2 (hereinafter referred to as the hoisting unit 2) that also serves as a hoisting device are provided.

[0021] Thus, as shown in FIG. 2, the elevator climbing installation system 1 includes the permanent elevator 4 suspended from the machine room unit 3 and the hoisting unit 2 that is hoisted to a predetermined position in the elevator shaft 6 by a hoisting machine 5 and climbs the machine room unit 3 and the permanent elevator 4 by a winding device 7. The hoisted hoisting unit 2 and machine room unit 3 are installed and supported on a predetermined support beam 20 of the building by a telescopic beam 10 that can freely expand and contract.

[0022] (Installation procedure by climbing) FIG. 2 shows an explanatory diagram of the installation procedure by climbing the elevator. The installation procedure by climbing is shown from Step 1 to Step 4.

[0023] In Step 1, equipment such as the lifting unit 2, the machine room unit 3, and the permanent elevator 4 are placed inside the elevator shaft 6. When the lifting unit 2 is installed on the Nth floor, the machine room unit 3 is installed on the N-2nd floor, and the permanent elevator 4 is installed on the N-4th floor. The lifting unit 2 and the machine room unit 3 are connected by an electric chain hoist 7. The machine room unit 3 and the permanent elevator 4 are connected by a wire 8.

[0024] In Step 2, construction of the building structure and elevator shaft 6 is carried out on the floors above the floor where the lifting unit 2 is installed. Subsequently, the installation of guide rails 12 and elevator landings is carried out using the temporary decks 13 on each floor. During this time, the roof portion of the lifting unit 2 is used as a work platform 9.

[0025] In step 3, when the elevator shaft 6 reaches the next installation floor, the lifting unit 2 is lifted by the tower crane 5 and reinstalled. That is, in step 3 of Figure 2, the lifting unit 2 is climbed by the tower crane 5 from the position of the lifting unit 2' before lifting to the position of the lifting unit 2. The lifting unit 2 is lifted inside the elevator shaft 6 by tightening the telescopic beam 10, and the telescopic beam 10 is extended and erected and supported on the designated support beam 20 of the building.

[0026] In step 4, the machine room unit 3 is climbed by an electric chain hoist 7 built into the lifting unit 2. That is, in step 4 of Figure 2, the machine room unit 3 is lifted by the electric chain hoist 7 from the machine room unit position 3' before lifting to the position of the machine room unit 3 by climbing.

[0027] (Steps in the installation cycle) Figure 3 shows an explanatory diagram of the steps in the elevator installation cycle for each floor. If the lifting unit 2 is installed on the Nth floor at the start of elevator installation, the machine room unit 3 will be installed on the N-2nd floor. Also, the service floors of the permanent elevator 4 will be N-4th floor or lower. Here, "service floor" refers to the floors on which the construction related to the permanent elevator 4 is completed and the permanent elevator 4 is usable. In step 1, when the lifting unit 2 is installed on the Nth floor, the machine room unit 3 is installed on the N-2nd floor, and the highest service floor of the permanent elevator 4 will be N-4th floor or lower. In step 2, the walls of the elevator shaft 6 above the Nth floor are constructed, and temporary decks 13 are erected on each floor within the elevator shaft 6. This temporary deck 13 will serve as a work platform 9 for working inside the elevator shaft 6. The machine room unit 3, which prevents rainwater from entering the permanent elevator 4, will be installed on the N-2 floor. The permanent elevator 4 will be installed on the N-4 floor, with the N-4 floor and below being the highest service floors. Workers will then board the elevator car on the N-3 floor to perform work related to the permanent elevator 4.

[0028] In Step 3, a waterproofing treatment is applied to the four sides of the temporary deck 13 installed at the top floor (N+7th floor) level, making the temporary deck 13 function as a waterproof roof. In Step 4, the upper work platform 16 of the lifting unit 2 and the temporary decks 13 installed on each floor in Step 1 are used as work scaffolding 9, and the elevator guide rails 12 are erected sequentially in the space within the elevator shaft 6 from the lower floors up to the N+7th level. In Step 5, as preparation for climbing, the temporary decks 13 below the N+6th floor are temporarily removed. In Step 6, the lifting unit 2 is lifted using a lifting machine such as a tower crane 5 and installed on the N+6th floor. In Step 7, the machine room unit 3 and the permanent elevator 4 are lifted together at a constant speed, and the climbing is performed. To ensure the safety of the climbing, this lifting is performed using the electric chain block 7 built into the lifting unit 2, rather than the tower crane 5. Finally, the installation work of each unit and the permanent elevator 4 is carried out, completing one cycle of the climbing process. Furthermore, it is possible to climb up to approximately 30 meters at a time.

[0029] (Lifting unit with built-in electric chain hoist and telescopic beam) Figure 4 shows a detailed perspective view of the upper work platform 16 and lifting unit 2, which incorporates an electric chain hoist 7 and an extendable beam 10. The lifting unit 2 according to the present invention serves both the function of an upper work platform 16 and the function of lifting the machine room unit 3 and the permanent elevator 4 by incorporating an electric chain hoist 7. That is, as the construction of the elevator shaft 6 progresses and the elevator shaft 6 on the floors above the installation floor of the lifting unit 2 is constructed, the installation of the guide rails 12 and the landings on the service floors proceeds. At this time, the roof portion of the lifting unit 2 can be used as a work platform 9. Then, when the floor to which the next lifting unit 2 will be installed is reached, the lifting unit 2 is lifted by the tower crane 5 and reinstalled. After that, the machine room unit 3 is lifted at a constant speed using the electric chain hoist 7 incorporated in the lifting unit 2 and installed on the upper floor, thereby increasing the number of service floors of the permanent elevator 4. In this embodiment, the electric chain hoist 7 is used to perform what is known as "four-point lifting 17". The loads of the machine room unit 3 and the lifting unit 2 are supported by a telescopic beam 10, which has a telescopic mechanism, being erected on the beam 18 of the building. Specifically, during climbing, the telescopic beam 10 is hoisted up inside the elevator shaft 6 while stored in the sheath pipe 23, and then extended from the sheath pipe 23 to be erected and supported on the designated support beam 20 of the building. The term "telescopic" refers to a mechanism that allows the overall length to be changed by combining tubes of different sizes and extending or retracting them, similar to a portable telescope.

[0030] Figure 5 also shows detailed views of the machine room unit 3 and the permanent elevator 4. Figure 5(a) is a front view of the expansion beam 10. Figure 5(b) is a side view of Figure 5(a). The machine room unit 3 suspends the permanent elevator 4 with wires 8.

[0031] Furthermore, Figure 6 shows a detailed view of the telescopic beam 10 provided in the lifting unit 2 and the machine room unit 3. The telescopic beam 10 is built into the sheath pipe 23 in a telescopic manner and can be extended or retracted. During climbing, the telescopic beam 10 is retracted into the sheath pipe 23 and lifted through the elevator shaft 6 while avoiding collisions or contact. When it reaches the support members 18 fixed to the building's support beams 20 by welding, the sheath pipe 23 is extended from the telescopic beam 10. This extension and retraction is performed manually. As shown in Figure 6, the extended telescopic beam 10 is then fixed to the support members 18 by shims 19. Note that Figure 6 shows the telescopic beam 10 being extended at one end of the sheath pipe 23, and the telescopic beam 10 is similarly extended at the other end of the sheath pipe 23 and fixed to the support members 18 by shims 19. Thus, insertion openings 21a on the sheath pipe side are provided at both ends of the sheath pipe 23, and their positions overlap with the insertion openings 21b on the retractable beam side where the sheath pipe is stored. Therefore, the position of the retractable beam 10 can be fixed relative to the sheath pipe 23 by inserting the fixing pins into the respective fixing pin insertion openings of the overlapping sheath pipe 23 and the retractable beam 10. In addition, opening reinforcement plates 22 are provided at these fixing pin insertion openings to reinforce the openings.

[0032] (Climbing setup method) The present invention illustrates an elevator climbing installation method. The method consists of the following steps: installing a lifting unit 2 on the Nth floor, a machine room unit 3 on the N-2nd floor, and a permanent elevator 4 on the N-4th floor; constructing the walls of the elevator shaft 6 above the Nth floor and laying temporary decks 13 on each floor within the elevator shaft 6; applying waterproofing treatment to the four sides of the temporary deck 13 at the top floor level; using the upper work platform 16 of the lifting unit 2 and the temporary decks 13 on each floor as a work platform 9 to erect the elevator guide rails 12 up to the N+7th floor; temporarily removing the temporary decks 13 below the N+6th floor in preparation for climbing; lifting the lifting unit 2 with a lifting machine such as a tower crane 5 and installing it on the N+6th floor; lifting the machine room unit 3 and the permanent elevator 4 together with an electric chain block 7 and climbing them; and performing installation work on each unit and the permanent elevator 4.

Therefore, the present invention is not limited to the embodiments described and can be modified in various forms as long as it does not depart from the scope of the technical idea set forth in the claims.
