Description

Core-integrated elevator modular structure and modular elevator construction method using the same

[0001] The present invention relates to a core-integrated elevator modular structure that enables the construction of an elevator structure using a modular unit in which an elevator core constituting the structure of an elevator shaft and an elevator structure is integrated, and a modular elevator construction method using the same.

[0002] Conventional elevator construction methods have involved assembling the individual components forming the elevator on-site after the building's steel frame has been installed. Consequently, this approach has resulted in prolonged construction periods due to the significant amount of time required for on-site installation, a high incidence of safety accidents associated with working at heights, and problems such as increased on-site operating costs and extended installation durations.

[0003] In addition, due to the specialized nature of elevator installation, on-site work is primarily performed vertically. Since this vertical work makes it impossible to carry out installation work simultaneously in the vertical direction, there is a problem in that it is impossible to shorten the schedule.

[0004] The method introduced to solve these problems is the construction method of modular elevator structures.

[0005] The modular construction method involves installing individual modules, most of which are assembled in a factory, on-site. This method offers the advantages of simplified on-site construction, reduced work at heights, and guaranteed consistent quality.

[0006] However, conventional modular construction methods have adopted a approach where the elevator core is constructed on-site in advance, and modular units manufactured in a factory are fed into the core at the site using a crane.

[0007] This approach presents a problem in that constructing the entire building using a modular method results in non-modular sections, which extends the overall construction period. Additionally, the process of stacking modules around an elevator core involves numerous process-related risks.

[0008] Accordingly, it is necessary to develop structures and construction methods that enable the entire elevator structure construction process to be carried out using a modular approach.

[0009] The present invention was developed to solve the problems of the aforementioned conventional modular elevator structure construction method. The objective of the present invention is to provide a core-integrated elevator modular structure that enables the entire elevator structure construction process to be carried out in a modular manner, and a modular elevator construction method using the same.

[0010] Another objective of the present invention is to provide a core-integrated elevator modular structure that prevents the overall construction period of a building to which a modular construction method is applied from being prolonged, and a modular elevator construction method using the same.

[0011] Another objective of the present invention is to provide a core-integrated elevator modular structure and a modular elevator construction method using the same, which minimizes high-altitude work at the construction site, lowers the difficulty of on-site construction, and maintains consistent construction quality.

[0012] According to one aspect of the present invention, an elevator modular structure is provided that includes a core-integrated elevator modular structure comprising a frame forming an elevator core, comprising: an upper module (100) in which a hoisting machine (1) and a governor (2) are installed; an intermediate module (200) in which an elevator car (3) and a counterweight (4) move in a moving space (10); and a lower module (300) in which a buffer (6) is installed, wherein the intermediate module (200) is stacked in a plurality between the upper module (100) and the lower module (300).

[0013] In this case, the upper module (100) may be an elevator modular structure characterized by including: a first main body frame (110); a first support frame (120) that supports the hoisting machine (1) and the governor (2); and a lifting beam (130) connected to a lifting machine that lifts the first main body frame (110).

[0015] Additionally, the above intermediate module (200) may be an elevator modular structure characterized by further including a support member (240) for supporting temporary scaffolding, which is installed on the above moving space (10).

[0016] Additionally, the above intermediate module (200) may be stacked in multiple layers, and may further include an uppermost intermediate module (200A) located on the uppermost layer among the stacked intermediate modules (200), wherein the uppermost intermediate module (200A) is characterized by having a mounting frame (250) formed thereon on which the elevator car (3) is mounted.

[0017] Additionally, the above intermediate module (200) may be an elevator modular structure characterized by further including a second rail (260) that guides the movement path of the counterweight (4) and is installed on the movement space (10).

[0018] Additionally, the elevator modular structure may further include a bottom layer intermediate module (200B) located at the bottom layer among the multiple stacked intermediate modules (200), wherein the bottom layer intermediate module (200B) is characterized by having a counterweight mounting frame (270) formed therein to support the counterweight (4).

[0019] Additionally, the elevator modular structure may further include a guide pin (211) formed on the upper surface of the second main body frame (210) and inserted into a coupling hole (111) formed on the lower surface of the first main body frame (110).

[0020] Additionally, the lower module (300) may be an elevator modular structure characterized by including a third main body frame (310); and a buffer frame (320) on which a buffer (6) is installed to provide a buffering force for the elevator car (3) moved to the lowest intermediate module (200B).

[0021] Additionally, the elevator modular structure may be characterized in that the first main body frame (110), the second main body frame (210), and the third main body frame (320) are connected to form the elevator core.

[0022] According to another aspect of the present invention, a modular elevator construction method using an elevator modular structure is provided, comprising: a first step (S100) of sequentially stacking the lower module (300), a plurality of the intermediate modules (200), and the upper module (100) at a place where the elevator structure is to be constructed; a second step (S200) of installing a rope connecting the elevator car (3) located in the uppermost intermediate module (200A) and the counterweight (4) located in the lowest intermediate module (200B); and a third step (S300) of removing the mounting frame (250) installed in the uppermost intermediate module (200A).

[0041] An embodiment of a core-integrated elevator modular structure according to the present invention and a modular elevator construction method using the same will be described in detail with reference to the attached drawings. In describing with reference to the attached drawings, identical or corresponding components are assigned the same drawing number, and redundant descriptions thereof will be omitted.

[0042] Furthermore, terms such as "first," "second," etc. used below are merely identifiers to distinguish identical or corresponding components, and identical or corresponding components are not limited by terms such as "first," "second," etc.

[0043] In addition, regarding the contact relationship between each component, the term "combination" is used not only to mean cases where each component is in direct physical contact with each other, but also to encompass cases where another component is interposed between each component and each component is in contact with that other component.

[0044] The present invention relates to a core-integrated elevator modular structure that enables the entire process of an elevator structure, including an elevator core constituting an elevator shaft, to be constructed in a modular manner.

[0045] Conventional construction methods for modular elevator structures have involved first constructing a frame forming the elevator core at the construction site and then stacking individual modules manufactured in a factory onto the elevator core (Fig. 1).

[0046] Unlike this, the present invention has the feature that the construction of the entire elevator structure can be completed simply by stacking and combining individual modules manufactured in a factory at the site (Fig. 2).

[0047] An elevator modular structure according to one embodiment of the present invention for this purpose includes an upper module (100) in which a hoisting machine (1) and a governor (2) are installed, an intermediate module (200) that forms a moving space (10) in which an elevator car (3) and a counterweight (4) move, and a lower module (300) in which a buffer (6) is installed (Fig. 3).

[0048] In this case, the upper module (100) may include a first main body frame (110), a first support frame (120) that supports a hoist (1) and a governor (2) as a module stacked on the top layer when stacking each module, and a lifting beam (130) connected to a lifting machine that lifts the first main body frame (110) (Figs. 4, 5).

[0049] The first support frame (120) not only provides support for the installation of the hoist (1) and governor (2), but can also serve as a reinforcing member to withstand the load generated during the movement and installation process of the upper module (100).

[0050] In addition, since the height at which the hoisting machine (1) and governor (2) are installed varies depending on the capacity or speed of the elevator car (3) being installed, there is a feature of having a separate structure separated from the first main body frame (110) to provide variability in installation at the site.

[0051] Additionally, the first support frame (120) may separately provide an installation plate (121) for stable installation and maintenance of the hoisting machine (1) and the governor (2).

[0052] An intermediate module (200) of an elevator modular structure according to one embodiment of the present invention may include a second main body frame (210) forming a movement space (10), a door frame (220) on which an elevator door (5) is installed, a first rail (230) installed on the movement space (10) and guiding the movement path of an elevator car (3), and a second rail (260) installed on the movement space (10) and guiding the movement path of a counterweight (4) (Figs. 7 to 10).

[0053] Since the door frame (220) is configured to install the elevator door (5), a variable joint may be used to correct for installation errors. That is, the door frame (220) is not welded to the second main body frame (210) to become an integral part, but can be pre-fabricated using a joint member that includes an elongated hole configuration. Subsequently, during the installation process of the elevator door (5), it is possible to adjust the position of the door frame (220) in detail according to the specifications of the door (5).

[0054] Additionally, the intermediate module (200) is installed on the moving space (10) and may include a support member (240) for supporting the temporary scaffolding.

[0055] The support member (240) can serve as a support structure for workers and as a temporary scaffolding for work when workers install a continuous member, such as the first rail (230) or the second rail (260), on the second main body frame (210).

[0056] According to one embodiment of the present invention, an intermediate module (200) of an elevator modular structure is stacked in multiple numbers (Fig. 13), and further includes an uppermost intermediate module (200A) located at the top of the stacked intermediate modules (200), wherein a mounting frame (250) on which an elevator car (3) is mounted may be formed on the uppermost intermediate module (200A). A mounting frame (250) is not formed on the other multiple intermediate modules (200).

[0057] Accordingly, the uppermost intermediate module (200A) can be manufactured with the elevator car (3) mounted on it and transported to the construction site. Alternatively, depending on the crane capacity, the elevator car (3) can be brought into the uppermost intermediate module (200A) during the modular stacking process at the site rather than at the manufacturing plant.

[0058] Additionally, the apparatus further includes a bottom layer intermediate module (200B) located at the bottom layer among the multiple stacked intermediate modules (200), wherein a counterweight mounting frame (270) supporting a counterweight (4) may be formed in the bottom layer intermediate module (200B).

[0059] Accordingly, the lowest intermediate module (200B) can be manufactured with a counterweight (4) mounted thereon and transported to the construction site.

[0060] Subsequently, at the construction site, the lower module (300), a plurality of intermediate modules (200), and the upper module (100) are stacked in sequence, and the elevator car (3) located in the uppermost intermediate module (200A) and the counterweight (4) located in the lowest intermediate module (200B) are connected using a rope to construct the elevator structure.

[0061] An intermediate module (200) of an elevator modular structure according to one embodiment of the present invention may further include a guide pin (211) formed on the upper surface of a second main body frame (210) and inserted into a coupling hole (111) formed on the lower surface of a first main body frame (110) (Figs. 7, 9).

[0062] Accordingly, the present invention has the effect of maintaining the correct position of the intermediate modules (200) located at the top and bottom by connecting the connecting hole (111) and the guide pin (211) in the connection between the intermediate modules (200) that are stacked in multiple numbers.

[0063] In one embodiment of the present invention, the lower module (300) of another elevator modular structure may include a buffer frame (320) on which a buffer (6) is installed to provide a buffering force for the elevator car (3) moved to the third main body frame (310) and the lowest intermediate module (200B) (Figs. 11, 12).

[0064] According to the present invention, since the first main body frame (110), the second main body frame (210), and the third main body frame (320) are connected to form an elevator core (elevator shaft), there is an advantage that the entire elevator structure including the elevator core can be constructed by simply stacking the upper module (100), the middle module (200), and the lower module (300) when performing modular construction.

[0065] A modular elevator construction method using an elevator modular structure according to one embodiment of the present invention will be described below.

[0066] The elevator construction method according to the present invention may include a first step (S100) of sequentially stacking a lower module (300), a plurality of intermediate modules (200), and an upper module (100) at a place where an elevator structure is to be constructed, a second step (S200) of installing a rope connecting an elevator car (3) located in the uppermost intermediate module (200A) and a counterweight (4) located in the lowest intermediate module (200B), and a third step (S300) of removing the mounting frame (250) installed in the uppermost intermediate module (200A).

[0067] The foregoing merely describes some preferred embodiments that can be implemented by the present invention. As is well known, the scope of the present invention should not be interpreted as being limited to the above embodiments, and all technical concepts that share the fundamental principles with the technical concept of the present invention described above shall be considered to be included within the scope of the present invention.
