Description

Technical Field

[0001] This utility model relates to the field of steel-concrete section installation technology, and more specifically, to a steel-concrete section installation device. Background Technology

[0002] In steel-concrete composite bridges, a steel-concrete composite section is typically installed at the connection point between the steel beams and the concrete beams. Currently, the installation of this section usually involves setting up supports at the bottom of the composite section, then using a crane to lift it onto temporary supports for precise positioning and fixation. However, due to the relatively large weight of the steel-concrete composite section, large lifting equipment is usually required, and the temporary supports require a significant amount of material. As the bridge height increases, the economic efficiency of installing the steel-concrete composite section decreases. Utility Model Content

[0003] The problem this invention addresses is: how to reduce the cost of installing steel-concrete composite sections.

[0004] To address the aforementioned problems, this utility model provides a steel-concrete section installation device, comprising a hanging basket for pre-installation on a concrete beam, a vertical lifting structure, a horizontal sliding structure, and a lifting device for connecting to the steel-concrete section. The bottom frame of the hanging basket is positioned above the concrete beam, and at least a portion of the top frame of the hanging basket extends horizontally beyond the end of the concrete beam to be located above the area where the steel-concrete section is to be installed. The vertical lifting structure is connected to the lifting device and used to lift the lifting device. The horizontal sliding structure includes a driving structure, a slide rail, and a slider slidably connected to the slide rail. The slide rail extends horizontally and is positioned on the hanging basket. The slider is connected to the vertical lifting structure, and the driving structure is used to drive the slider to slide along the slide rail.

[0005] Optionally, the steel-concrete section installation device further includes multiple sets of leveling structures movably mounted on the hanging basket. Each set of leveling structures includes a jacking pad and two jacks that are symmetrical about the vertical direction. The driving ends of the two jacks are respectively driven connected to the jacking pad. The jacking pad is used to connect to the steel-concrete section via a sling.

[0006] Optionally, the lifting device includes a first lifting seat connected to the drive end of the vertical lifting structure, a second lifting seat hinged to the first lifting seat, and a third lifting seat slidably connected to the second lifting seat in the horizontal direction, the third lifting seat being used to connect to the steel-concrete section.

[0007] Optionally, the lifting device further includes a locking screw and two locking nuts. The locking screw extends horizontally through and out of the second lifting seat. The axial end of the locking screw is connected to the third lifting seat. The second lifting seat is located between the two locking nuts. The two locking nuts are threadedly connected to the locking screw and are used to abut against the second lifting seat after being tightened.

[0008] Optionally, the third hanger is configured as a U-shaped structure with the opening facing downwards, and includes a first horizontal beam in the horizontal direction and two second vertical beams in the vertical direction. The two second vertical beams are respectively vertically connected to two ends in the length direction of the first horizontal beam, and the two ends of the two second vertical beams away from the first horizontal beam are respectively used to connect with the steel-concrete section. The first horizontal beam is slidably connected to the second hanger.

[0009] Optionally, the second vertical beam is used to connect to the lifting lug on the reinforced concrete section via a pin.

[0010] Optionally, multiple lifting lugs are provided, and the multiple lifting lugs are symmetrically distributed about the center of gravity of the steel-concrete section.

[0011] Optionally, the steel-concrete section installation device further includes a first code plate, one end of which is used to connect to the bottom beam of the concrete beam, and the other end of which is suspended and used to connect to the bottom beam of the steel-concrete section.

[0012] Optionally, the steel-concrete section installation device further includes a second code plate, the second code plate including a horizontal part extending in the horizontal direction and a vertical part extending in the vertical direction, one end of the horizontal part in the horizontal direction is used to connect with the top beam of the concrete beam through a pre-embedded part, the other end of the horizontal part in the horizontal direction is connected to the vertical part, the vertical part is located below the horizontal part and is used to abut against the top beam of the steel-concrete section.

[0013] Optionally, the bottom of the hanging basket is used to be installed on the concrete beam via embedded parts.

[0014] Compared with related technologies, the steel-concrete section installation device of this utility model utilizes a hanging basket pre-installed on a concrete beam, allowing the hanging basket to form a foundation support on the concrete beam without the need for additional lifting equipment on the ground. The bottom frame of the hanging basket is positioned above the concrete beam, and at least a portion of the top frame of the hanging basket extends horizontally beyond the end of the concrete beam to be located above the area where the steel-concrete section to be installed. This top frame provides a support position above the area where the steel-concrete section to be installed, thus satisfying the requirement for vertical lifting structure to hoist the steel-concrete section to the area where it is to be installed. Furthermore, with a horizontally extending slide rail positioned on the hanging basket, the slide rail is supported and positioned by the hanging basket. This allows the slider to slide accurately and stably along the extension direction of the track. Through the connection between the slider and the vertical lifting structure, the slider's sliding motion enables the horizontal adjustment of the vertical lifting structure. This allows the vertical lifting structure to be moved above the reinforced concrete section. Furthermore, the horizontal adjustment of the vertical lifting structure prevents interference between the reinforced concrete section and the concrete beam. Therefore, after the lifting device is connected to the reinforced concrete section, it not only enables vertical lifting of the section but also horizontal adjustment. Moreover, no additional temporary supports or large cranes are required during erection, thus reducing the cost of installing the reinforced concrete section. Attached Figure Description

[0026] It should be noted that the terms "first," "second," etc., used in the specification, claims, and accompanying drawings of this utility model are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence. It should be understood that such data can be interchanged where appropriate so that the embodiments of this utility model described herein can be implemented in sequences other than those illustrated or described herein.

[0027] Combination Figures 1 to 4 As shown, this utility model embodiment provides a steel-concrete section installation device, including a hanging basket 2 for pre-installation on a concrete beam 1, a vertical lifting structure 3, a horizontal sliding structure 4, and a lifting device 6 for connection with a steel-concrete section 5. The bottom frame of the hanging basket 2 is located above the concrete beam 1, and at least a portion of the top frame of the hanging basket 2 extends horizontally beyond the end of the concrete beam 1 to be located above the area of ​​the steel-concrete section 5 to be installed. The vertical lifting structure 3 is connected to the lifting device 6 and is used to lift the lifting device 6. The horizontal sliding structure 4 includes a driving structure 41, a slide rail 42, and a slider 43 slidably connected to the slide rail 42. The slide rail 42 extends horizontally and is located on the hanging basket 2. The slider 43 is connected to the vertical lifting structure 3. The driving structure 41 is used to drive the slider 43 to slide along the slide rail 42.

[0028] Specifically, the structure of hanging basket 2 is as follows: Figure 1 As shown, the side of the hanging basket 2 can be a parallelogram-shaped frame structure, with multiple support beams installed within this frame structure to ensure the stability of the hanging basket 2. The bottom frame of the hanging basket 2 is located above the concrete beam 1, and at least part of the top frame extends horizontally beyond the end of the concrete beam 1 to be located above the area where the reinforced concrete section 5 is to be installed. The vertical lifting structure 3 and the horizontal sliding structure 4 are both installed on the top frame of the upper end of the hanging basket 2. The slide rail 42 extends horizontally (Y-axis) and is installed on the hanging basket 2. The slider 43 is slidably connected to the slide rail 42. The driving structure 41 can be a jack that extends and retracts horizontally. This jack drives the slider 43 to slide along the slide rail 42. The slider 43 is connected to the vertical lifting structure 3 so that the vertical lifting structure 3 can move horizontally. During construction, the drive structure 41 drives the slider 43 to move away from the concrete beam 1 on the slide rail 42 (i.e., the slider 43 moves towards the negative Y-axis), allowing the slider 43 to move the vertical lifting structure 3 away from the concrete beam 1. This ensures that the vertical lifting structure 3 is positioned above the reinforced concrete section 5. Simultaneously, it prevents interference between the reinforced concrete section 5 and the concrete beam 1, as well as the protruding reinforcing bars on the concrete beam 1, during the lifting process. The vertical lifting structure 3 can be a continuous jack. The drive end of the vertical lifting structure 3 is connected to the lifting device 6 via a sling. The lifting device 6 is connected to the reinforced concrete section 5 (the combined reinforced concrete section). When the vertical lifting structure 3 lifts the reinforced concrete section 5 to the height required for the installation of the concrete beam 1, the drive structure 41 drives the slider 42 to slide towards the concrete beam 1, causing the vertical lifting structure 3 to slide towards the concrete beam 1. Under the drive of the vertical lifting structure 3, the reinforced concrete section 5 moves towards the concrete beam 1 and, after being inserted and positioned with the protruding reinforcing bars on the concrete beam 1, the connection between the reinforced concrete section 5 and the concrete beam 1 is achieved.

[0029] Therefore, in this embodiment, the hanging basket 2 is pre-installed on the concrete beam 1, forming a basic support on the concrete beam 1 without the need for additional lifting equipment on the ground. The bottom frame of the hanging basket 2 is positioned above the concrete beam 1, and at least a portion of the top frame of the hanging basket 2 extends horizontally beyond the end of the concrete beam 1 to be located above the area where the reinforced concrete section 5 is to be installed. This provides a support position above the area where the reinforced concrete section 5 is to be installed, thus satisfying the vertical lifting structure 3's hoisting of the reinforced concrete section 5 to the area where the reinforced concrete section 5 is to be installed. After the slide rail 42 extends horizontally onto the hanging basket 2, the slide rail 42 is supported and positioned by the hanging basket 2, allowing the slider 43 to... It can slide stably and accurately along the extension direction of the slide rail 42, and then connect with the vertical lifting structure 3 through the slider 43. The sliding of the slider 43 can realize the adjustment of the position of the vertical lifting structure 3 in the horizontal direction, so that the vertical lifting structure 3 can be moved above the steel-concrete section 5. The adjustment of the position of the vertical lifting structure 3 in the horizontal direction can avoid interference between the steel-concrete section 5 and the concrete beam 1. Thus, after the lifting device 6 is connected to the steel-concrete section 5, it can not only realize the vertical lifting of the steel-concrete section 5, but also realize the adjustment of the position of the steel-concrete section 5 in the horizontal direction. During the erection process, no additional temporary supports or large cranes or other equipment are required, thereby reducing the cost of steel-concrete composite section installation.

[0030] Optionally, combined Figure 1 and Figure 7 As shown, the steel-concrete section installation device also includes multiple sets of leveling structures 7 that are movably mounted on the hanging basket 2. Each set of leveling structures 7 includes a lifting pad 71 and two jacks 72 that are symmetrical about the vertical direction. The driving ends of the two jacks 72 are respectively driven connected to the lifting pad 71. The lifting pad 71 is used to connect to the steel-concrete section 5 through a sling.

[0031] Specifically, when the height of the steel-concrete section 5 is sufficient for installation on the concrete beam 1, the steel-concrete section 5 is raised to the elevation position. If the front end of the steel-concrete section 5 deflects upward at the elevation position, the lifting pad 71 in the leveling structure 7 located above the rear end of the steel-concrete section 5 is connected to the rear end of the steel-concrete section 5 via a sling. Then, the two jacks 72 of the leveling structure 7 lift the lifting pad 71 to share the weight of the steel-concrete section 5 and lift the rear end of the steel-concrete section 5, keeping the steel-concrete section 5 horizontal. Then, the leveling structure 7 and the vertical lifting structure 3 can move together toward the concrete beam 1 to move the steel-concrete section 5 toward the concrete beam 1, thereby connecting the steel-concrete section 5 and the concrete beam 1. Each set of leveling structures 7 can be moved and installed on the concrete beam 1 by means of a railcar. That is, a rail is laid on the concrete beam 1, and a railcar is installed on the rail. The railcar moves along the length of the concrete beam 1 via the rail, and an installation area for the leveling structure 7 is set at the upper end of the railcar. In this installation area, a single set of leveling structures 7 is installed on the corresponding railcar by bolts, etc., so that the movement of the railcar can realize the movement of each set of leveling structures 7 toward the concrete beam 1.

[0032] In this way, multiple sets of leveling structures 7 are moved and installed on the hanging basket 1, and the driving ends of the two jacks 72 of each set of leveling structures 7 are respectively driven to the lifting pad 71. The lifting pad 71 is used to connect to the steel-concrete section 5 through the sling, which can realize the fine adjustment of the position of the steel-concrete section 5 at the elevation position, further ensuring that the steel-concrete section 5 can remain horizontal, so as to improve the installation efficiency of the steel-concrete section 5.

[0033] Optionally, combined Figure 6 As shown, the lifting device 6 includes a first lifting seat 61 connected to the drive end of the vertical lifting structure 3, a second lifting seat 62 hinged to the first lifting seat 61, and a third lifting seat 63 slidably connected to the second lifting seat 62 in the horizontal direction. The third lifting seat 63 is used to connect to the steel-concrete section 5.

[0034] Specifically, the first lifting seat 61, the second lifting seat 62, and the third lifting seat 63 are distributed from top to bottom. The upper end of the first lifting seat 61 is connected to the drive end of the vertical lifting structure 3 via a sling. The lower end of the first lifting seat 61 is hinged to the upper end of the second lifting seat 62. The lower end of the second lifting seat 62 is slidably connected to the third lifting seat 63, and the third lifting seat 63 can slide back and forth relative to the second lifting seat 62 in the horizontal direction (Y-axis direction). During construction, the third lifting seat 63 is connected to the reinforced concrete section 5. The drive end of the vertical lifting structure 3 is pre-lifted via the lifting point lifting device 6. If the pre-lifting of the reinforced concrete section 5 is... If it is found that the third lifting seat 63 is deflected relative to the second lifting seat 62 during the process, it indicates that the lifting of the steel-concrete section 5 is subject to eccentric loading. When eccentric loading occurs, the second lifting seat 62 is slid relative to the third lifting seat 63 to adjust the position of the second lifting seat 62 so that the direction of the tension force on the steel-concrete section 5 is consistent with the direction of gravity of the steel-concrete section 5. This ensures that the steel-concrete section 5 can remain horizontal during the lifting process and will not tilt. This reduces the time required to adjust the steel-concrete section 5 to be horizontal when it is lifted to the same height as the concrete beam 1, which not only improves construction efficiency but also improves construction safety.

[0035] Thus, by connecting the first lifting seat 61 to the drive end of the vertical lifting structure 3, the second lifting seat 62 hinged to the first lifting seat 61, and the third lifting seat 63 slidably connected to the second lifting seat 62 in the horizontal direction, and connecting the third lifting seat 63 to the steel-concrete section 5, the lifting seat 6 has multiple degrees of freedom, and the steel-concrete section 5 can be horizontally lifted by the relative sliding between the third lifting seat 63 and the second lifting seat 62, which not only improves construction efficiency but also improves construction safety.

[0036] Optionally, combined Figure 6 As shown, the lifting device 6 also includes a locking screw 64 and two locking nuts 65. The locking screw 64 extends horizontally through and out of the second lifting seat 62. The axial end of the locking screw 64 is connected to the third lifting seat 63. The second lifting seat 62 is located between the two locking nuts 65. The two locking nuts 65 are threadedly connected to the locking screw 64 and are used to abut against the second lifting seat 62 after being tightened.

[0037] Specifically, the length direction of the locking screw 64 is consistent with the sliding direction of the second lifting seat 62, that is, the locking screw 64 extends horizontally. The second lifting seat 62 is provided with a through hole, and the locking screw 64 is placed in the through hole. Both ends of the locking screw 64 extend out of the through hole and connect with the third lifting seat 63. When the positions of the second lifting seat 62 and the third lifting seat 63 are adjusted to ensure that the reinforced concrete section 5 is lifted horizontally, the two locking nuts 65 are tightened so that the two locking nuts 65 abut against the second lifting seat 62 respectively, thereby preventing relative sliding between the second lifting seat 62 and the third lifting seat 63 during the lifting of the reinforced concrete section 5, thus improving construction safety.

[0038] Thus, the second hanger 62 is located between two locking nuts 65, with the axial end of the locking screw 64 connected to the third hanger 63. The two locking nuts 65 are threadedly connected to the locking screw 64 and, after being tightened, abut against the second hanger 62. The two locking nuts 65 form a horizontal limit after abutting against the second hanger 62, so as to avoid relative sliding between the second hanger 62 and the third hanger 63 during the lifting of the steel-concrete section 5, thereby improving construction safety.

[0039] Optionally, combined Figure 6 As shown, the third hanger 63 is configured as a U-shaped structure with the opening facing downwards, and includes a first horizontal beam 631 in the horizontal direction and two second vertical beams 632 in the vertical direction. The two second vertical beams 632 are respectively vertically connected to the two ends of the first horizontal beam 631 in the length direction, and the two ends of the two second vertical beams 632 away from the first horizontal beam 631 are respectively used to connect with the steel-concrete section 5. The first horizontal beam 631 is slidably connected to the second hanger 62.

[0040] Specifically, the first crossbeam 631 extends horizontally along the Y-axis, meaning the length direction of the first crossbeam 631 is the Y-axis direction. The locking screw 64 mentioned above is located below the first crossbeam 631, and both ends of the locking screw 64 in the length direction are connected to the first crossbeam 631. Two second vertical beams 632 extend vertically and are located below the first horizontal beam 631. The two second vertical beams 632 are vertically connected to the two ends of the first horizontal beam 631 along its length. The two second vertical beams 632 and the first horizontal beam 631 together form a U-shaped structure with the opening facing downwards. The first horizontal beam 631 is slidably connected to the second lifting seat 62. The lower ends of the two second vertical beams 632 are connected to the steel-concrete section 5. During the lifting process of the steel-concrete section 5, the two second vertical beams 632 can achieve an indirect connection between the first horizontal beam 631 and the steel-concrete section 5 to avoid interference between the second lifting seat 62 and the steel-concrete section 5 when the first horizontal beam 631 slides relative to the second lifting seat 62, so as to ensure the efficiency of the position adjustment of the first horizontal beam 631.

[0041] Thus, by connecting two second vertical beams 632 perpendicularly to the two ends of the first horizontal beam 631, which is slidably connected to the second lifting seat 62, along its length, and by connecting the two ends of the two second vertical beams 632 away from the first horizontal beam 631 to the reinforced concrete section 5, the two second vertical beams 632 can achieve an indirect connection between the first horizontal beam 631 and the reinforced concrete section 5. This avoids interference between the second lifting seat 62 and the reinforced concrete section 5 when the first horizontal beam 631 slides relative to the second lifting seat 62, thereby ensuring the efficiency of the position adjustment of the first horizontal beam 631.

[0042] Optionally, combined Figure 6 As shown, the second vertical beam 632 is used to connect to the lifting lug 8 on the steel-concrete section 5 via a pin.

[0043] Specifically, the lower end of each second vertical beam 632 is connected to the lifting lug 8 on the steel-concrete section 5 via a pin. When the second vertical beam 632 is connected to the steel-concrete section 5, it is only necessary to connect the second vertical beam 632 and the corresponding lifting lug 8 via a pin, so as to improve the connection efficiency between the second vertical beam 632 and the steel-concrete section 5.

[0044] Optionally, combined Figure 6 As shown, there are multiple lifting lugs 8, which are symmetrically distributed about the center of gravity of the steel-concrete section 5.

[0045] Specifically, multiple lifting lugs 8 are located at the upper end of the reinforced concrete section 5 and connected to the reinforced concrete section 5. The multiple lifting lugs 8 are symmetrically distributed about the center of gravity of the reinforced concrete section 5. This ensures that when the two second vertical beams 632 are connected to the reinforced concrete section 5, the two second vertical beams 632 are respectively connected to the two lifting lugs 8 that are symmetrical about the center of gravity of the reinforced concrete section 5. This ensures that the reinforced concrete section 5 is lifted in a horizontal state, thereby reducing the time wasted on subsequent adjustments of the reinforced concrete section 5 due to tilting, and ensuring construction efficiency.

[0046] Optionally, combined Figure 5 As shown, the steel-concrete section installation device also includes a first code plate 9. One end of the first code plate 9 in the length direction is used to connect with the bottom beam of the concrete beam 1, and the other end of the first code plate 9 in the length direction is suspended and used to connect with the bottom beam of the steel-concrete section 5.

[0047] Specifically, the first mounting plate 9 can be a horizontal plate-like structure. The first mounting plate 9 extends horizontally, which is the length direction of the reinforced concrete section 5, and also the length direction of the first mounting plate 9. One end of the first mounting plate 9 in the length direction is connected to the bottom beam of the concrete beam 1 (the concrete beam 1 is located at the negative end of the Z-axis) through an embedded part. The other end of the first mounting plate 9 in the length direction is suspended. When the bottom beam of the reinforced concrete section 5 is connected to the bottom beam of the concrete beam 1, the suspended end of the first mounting plate 9 can be connected to the bottom beam of the reinforced concrete section 5. After the first mounting plate 9 is connected to the bottom beam of the reinforced concrete section 5, the installation and positioning of the bottom beam of the reinforced concrete section 5 can be realized, so as to ensure the accurate connection between the bottom beam of the reinforced concrete section 5 and the bottom beam of the concrete beam 1.

[0048] Thus, one end of the first code plate 9 along its length is used to connect with the bottom beam of the concrete beam 1, and the other end of the first code plate 9 along its length is suspended and connected with the bottom beam of the steel-concrete section 5. When the bottom beam of the steel-concrete section 5 is connected with the bottom beam of the concrete beam 1, the first code plate 9 can ensure the accurate connection between the bottom beam of the steel-concrete section 5 and the bottom beam of the concrete beam 1, thereby improving construction efficiency.

[0049] Optionally, combined Figure 5As shown, the steel-concrete section installation device also includes a second mounting plate 10. The second mounting plate 10 includes a horizontal part 11 extending in the horizontal direction and a vertical part 12 extending in the vertical direction. One end of the horizontal part 11 in the horizontal direction is used to connect with the top beam of the concrete beam 1 through a pre-embedded part. The other end of the horizontal part 11 in the horizontal direction is connected to the vertical part 12. The vertical part 12 is located below the horizontal part 11 and is used to abut against the upper end of the top beam of the steel-concrete section 5.

[0050] Specifically, the second mounting plate 10 can be a flat "L"-shaped block structure, including a horizontal part 11 extending in the horizontal direction and a vertical part 12 located below the horizontal part 11 and extending in the vertical direction. The vertical part 12 is connected to one end of the horizontal part 11 in the length direction. After connection, the area enclosed by the vertical part 12 and the horizontal part 11 forms a positioning groove. The second mounting plate 10 is engaged with the end of the top beam of the concrete beam 1 through the positioning groove. That is, the horizontal part 11 is connected to the upper end of the top beam of the concrete beam 1, and the vertical part 12 abuts against the side end of the top beam of the concrete beam 1. When the reinforced concrete section 5 is installed, the vertical part 12 abuts against the upper end of the reinforced concrete section 5, so that after the reinforced concrete section 5 is connected to the concrete beam 1, a height difference is formed between the upper end of the reinforced concrete section 5 and the upper end of the concrete beam 1 through the extension of the vertical part 12. After the second mounting plate 10 is removed, the existence of the height difference can leave room for secondary construction, so as to facilitate the subsequent secondary pouring construction on the reinforced concrete section 5.

[0051] Thus, the horizontal part 11 is fixed by connecting one end of the horizontal part 11 to the top beam of the concrete beam 1 through a pre-embedded part, and the other end of the horizontal part 11 is connected to the vertical part 12. The vertical part 12 is located below the horizontal part 11, so that the vertical part 12 can be suspended on the concrete beam 1 with the support of the horizontal part 11. The vertical part 12 abuts against the upper end of the top beam of the steel-concrete section 5. After the steel-concrete section 5 is connected to the concrete beam 1, the vertical part 12 creates a height difference between the upper ends of the steel-concrete section 5 and the concrete beam 1, so as to form a surplus for secondary construction, so as to facilitate the subsequent secondary pouring construction on the steel-concrete section 5.

[0052] Optionally, combined Figure 1 As shown, the bottom of the hanging basket 2 is used to install it onto the concrete beam 1 via embedded parts.

[0053] Specifically, the bottom of the hanging basket 2 is the end facing the negative Z-axis, which can be understood as the bottom beam of the hanging basket 2. The bottom beam of the hanging basket 2 is installed on the concrete beam 1 through embedded parts. The embedded parts may include I-beams installed on the concrete beam 1 by embedded bolts. The bottom beam of the hanging basket 2 and the I-beams are detachably connected by heavy-duty bolts. This simplifies the installation between the hanging basket 2 and the concrete beam 1 during construction.

[0054] Thus, by installing the hanging basket 2 onto the concrete beam 1 through embedded parts at the bottom, the setting of embedded parts can reduce large changes in the structure of the concrete beam 1, thereby protecting the structure of the concrete beam 1. In the process of installing the hanging basket 2, the requirements on the structure of the concrete beam 1 can be reduced by directly installing the hanging basket 2 onto the concrete beam 1, thereby reducing the difficulty of installing the hanging basket 2 on the concrete beam 1 and improving the installation efficiency of the hanging basket 2.

[0055] Although the present invention has been disclosed above, its protection scope is not limited thereto. Those skilled in the art can make various changes and modifications without departing from the spirit and scope of the present invention, and all such changes and modifications will fall within the protection scope of the present invention.
