Description

Technical Field

[0001] This utility model relates to the field of building construction technology, and in particular to an attached lifting scaffold. Background Technology

[0002] Attached lifting scaffolding is an auxiliary support system used during the construction of high-rise and super high-rise buildings; it is also known as climbing scaffolding. When using climbing scaffolding, relevant regulations must be followed, such as… Figure 1 As shown, the height must not exceed 5 times the floor height. Therefore, in actual use, the climbing scaffold covers 4.5 floors of the main building in the vertical direction. The bottom 3 floors are already built, and the 4th floor is the main building to be constructed. There is also a protective height of more than 1.2 meters above the 4th floor. The climbing scaffold is constructed and lifted layer by layer. After each lift, the first wall-mounted support at the bottom will detach from the guide rail, leaving only two wall-mounted supports. At this time, the wall-mounted supports that have detached from the rail need to be removed and moved to the upper part (the 6th floor platform) for installation.

[0003] The existing method of rotating wall-mounted supports usually involves manually carrying them one by one up stairs to the upper part of the scaffold. This method is time-consuming and labor-intensive, affecting the progress of the entire project, and also poses certain safety hazards. Utility Model Content

[0004] To address at least one problem existing in the prior art, according to one aspect of the present invention, an attached lifting scaffolding system is provided, comprising:

[0005] The main frame includes a vertical main frame, multiple horizontal support trusses, multiple platform plates, and multiple doors. The vertical main frame is arranged opposite to the floors. The multiple horizontal support trusses are arranged separately on the vertical main frame along the vertical direction. The multiple doors, multiple platform plates, and multiple horizontal support trusses are arranged in a one-to-one correspondence. Each platform plate is provided with an opening. Each door and the corresponding platform plate are rotatably arranged to open or close the opening.

[0006] Multiple wall-mounted supports are spaced out on multiple floors to fix the vertical main frame to the floor.

[0007] The lifting mechanism is installed at the bottom of the platform plate and is used to lift the wall-mounted supports located below by sequentially passing through each of the openings.

[0008] In some embodiments, the frame body further includes a connector that connects the switch door and the platform plate.

[0009] In some embodiments, the connector includes a first angle iron, a second angle iron, and a bolt, wherein the first angle iron is connected to the switch door, the second angle iron is connected to the platform plate, and the bolt is connected to the first angle iron and the second angle iron respectively.

[0010] In some embodiments, a plurality of the connecting members are provided between each of the platform plates and the switch door.

[0011] In some embodiments, the switch door is located in the central region of the platform plate.

[0012] In some embodiments, the width and length of the opening are both in the range of 480-520 mm.

[0013] In some implementations, the lifting mechanism is a winch.

[0014] In some embodiments, the lifting mechanism is located at the bottom of the platform plate on the seventh layer from the bottom. In summary, the attached lifting scaffolding system provided by this utility model has the following technical effects:

[0015] By setting openings on the platform of the main frame and installing switchable doors at the corresponding opening positions, when the wall-mounted supports need to be raised after the completion of a certain floor, the openings can be opened by rotating the switchable doors, and the disassembled wall-mounted supports located below can be raised by the lifting mechanism. The wall-mounted supports can be passed through multiple openings from bottom to top and then raised to the upper floors before being installed on the corresponding floors. In this way, the installation efficiency of the entire attached lifting scaffolding system is improved, the construction efficiency is increased, and it is safer than manual handling.

Detailed Implementation

[0027] The following embodiments are further explanations and supplements to the present invention and do not constitute any limitation on the present invention.

[0028] Please see Figures 1 to 9 The attached lifting scaffolding system 100 provided in this embodiment of the utility model includes a frame body 10, a lifting mechanism 20 and multiple wall-mounted supports 30.

[0029] The main frame 10 includes a vertical main frame 11, multiple horizontal support trusses 12, multiple platform plates 13, and multiple opening and closing doors 14. The vertical main frame 11 is arranged opposite to the floors. The multiple horizontal support trusses 12 are arranged vertically on the vertical main frame 11. The multiple platform plates 13 are arranged one-to-one with the multiple horizontal support trusses 12. The multiple opening and closing doors 14 are arranged one-to-one with the multiple platform plates 13. Each platform plate 13 has an opening 131. Each opening and closing door 14 and the corresponding platform plate 13 are rotatably arranged to open or close the opening 131. Multiple wall supports 30 are arranged on multiple floors to fix the vertical main frame 11 to the wall. The lifting mechanism 20 is installed at the bottom of the platform plate 13 to lift the wall supports 30 located below by sequentially passing through each opening 131.

[0030] The aforementioned attached lifting scaffolding system 100, by setting openings 131 on the platform plate 13 of the frame body 10 and setting opening and closing doors 14 at the corresponding positions of the openings 131, allows the wall-mounted supports 30 to be lifted after the construction of a certain floor is completed. The openings 131 are opened by rotating the opening and closing doors 14, and the wall-mounted supports 30, which have been disassembled, are lifted by the lifting mechanism 20. The wall-mounted supports 30 are then passed through multiple openings 131 from bottom to top and can be lifted to the upper floors and then installed on the corresponding floors. In this way, the installation efficiency of the entire attached lifting scaffolding system 100 is improved, the construction efficiency is improved, and it is safer than manual handling.

[0031] Among them, the main frame 10, according to relevant regulations, must not be installed at a height greater than 5 times the height of the floor. Figure 1 As shown, in actual use, the main frame 10 covers four and a half floors of the building in the height direction. The bottom three floors are the walls of the existing floors, and the fourth floor is the floor to be built. There is a protective height of more than 1.2 meters above the fourth floor. The entire main frame 10 is equipped with six platform slabs 13. For ease of description, the first floor, second floor, third floor, fourth floor, and fifth floor are defined as 1F, 2F, 3F, 4F, and 5F, respectively. At the same time, according to relevant specifications, one wall-mounted support 30 is installed on each existing floor. Therefore, during use, the attached lifting scaffolding system 100 will have three wall-mounted supports 30 installed between it and the wall. As construction progresses layer by layer, the attached lifting scaffolding system 100 will be raised layer by layer. After each raising, the lowest wall-mounted support 30 will be disassembled to detach from the guide rail and the wall. At this point, there are only two wall-mounted supports 30 between the main frame 10 and the floor. The disassembled wall-mounted supports 30 need to be moved to the newly built floor 4F for installation. The process is as follows: Figures 1 to 6 As shown.

[0032] However, after the lowest wall-mounted support 30 is removed, existing technology involves moving it upwards. One method is to manually climb stairs and move it layer by layer, and the other is to use traction ropes from above. However, both methods are manual, time-consuming, and inefficient, thus affecting the overall construction efficiency of the floor.

[0033] In one embodiment of this utility model, to improve the efficiency of transporting the dismantled wall-mounted support 30, a lifting mechanism 20 is provided to transport the wall-mounted support 30. Specifically, the lifting mechanism 20 in this embodiment is a winch, which quickly lifts the wall-mounted support 30 by rotating a rope driven by a motor, thereby improving construction efficiency. Specifically, driven by the drive motor, the traction rope carries the wall-mounted support 30 through each of the openings 131 located above, thereby reaching the bottom of the 6th-layer platform plate 13. In other embodiments, the lifting mechanism 20 can also be set as an electric hoist, which can not only lift the wall-mounted support 30, but also move horizontally, thereby achieving the effect of fine adjustment in the horizontal direction, so as to adjust the position of the lifted wall-mounted support 30.

[0034] That is, in this embodiment, the lifting mechanism 20 is installed at the bottom of the seventh platform 13 counting upwards from the bottommost platform 13, so as to lift the wall-mounted support 30 to a position corresponding to the sixth platform 13. For ease of description, the platform 13s of the 1st to 7th floors are defined from bottom to top as 131, 132, 133, 134, 135, 136, and 137, respectively. That is, the lifting mechanism 20 is installed at the bottom of platform 137, lifting the wall-mounted support 30 to the position corresponding to platform 136, which is the position of the newly built floor 4F.

[0035] Please refer to Figures 7 to 9 In this embodiment, when the switch door 14 is installed relative to the platform plate 13, in order to ensure the safety of the entire attached lifting scaffold system 100 during construction, the frame body 10 also includes a connector 40. The connector 40 is connected between the switch door 14 and the platform plate 13. Thus, after the switch door 14 closes the opening 131 on the platform plate 13, there is still a connector 40 between the switch door 14 and the platform plate 13 to stably lock the switch door 14 onto the platform plate 13, preventing the switch door 14 from being opened during the construction of the attached lifting scaffold system 100 and affecting construction safety. For example, the connector 40 can be set as a quick-release self-locking structure. The quick-release self-locking structure is installed on the platform plate 13. After the switch door 14 closes the opening 131, the quick-release self-locking structure locks the switch door 14 onto the platform plate 13.

[0036] Please refer to Figure 7 and Figure 9 The door 14 is set to rotate relative to the platform plate 13 via the hinge 15.

[0037] Specifically, please refer to Figure 7To ensure the locking degree between the switch door 14 and the platform plate 13, the connector 40 includes a first angle iron 41, a second angle iron 42, and a bolt 43. The first angle iron 41 is connected to the switch door 14, the second angle iron 42 is connected to the platform plate 13, and the bolt 43 is connected to the first angle iron 41 and the second angle iron 42 respectively. In this way, the first angle iron 41 and the second angle iron 42, with their simple structure, are connected to the switch door 14 and the platform plate 13 respectively, and the two are then fixed by the bolt 43. This ensures the stability of the connection between the switch door 14 and the platform plate 13 when it is not needed to be opened. At the same time, the first angle iron 41, the second angle iron 42, and the bolt 43 are readily available construction parts during construction, which has the advantage of low cost.

[0038] Understandably, in order to ensure the connection stability between the switch door 14 and the platform plate 13, multiple connectors 40 are provided between each platform plate 13 and the switch door 14, so as to lock the switch door 14 through the multiple connectors 40, so as to lock the switch door 14 onto the platform plate 13.

[0039] Specifically, please refer to Figure 7 Each door 14 and platform plate 13 is provided with four connectors 40. Every two connectors 40 form a pair. The connectors 40 in each pair are close together and there is a certain gap between the two pairs of connectors 40, so that the two pairs of connectors 40 are separated and the door 14 is stably locked on the platform plate 13.

[0040] Please see Figure 8 In this design, when the platform plate 13 has an opening 131, the door 14 is located in the middle area of ​​the platform plate 13. That is, the length of the opening 131 is less than the length of the platform plate 13, and the width of the opening 131 is less than the width of the platform plate 13. In this way, the size of the opening 131 can be adapted to the size of the wall-mounted support 30. At the same time, it is located in the middle area of ​​the platform plate 13, and none of the four sides of the opening 131 are connected to the edge of the platform plate 13, so as to ensure the structural strength of the entire platform plate 13.

[0041] The wall-mounted support 30 has dimensions of 330×350×350 mm. Specifically, to ensure the opening 131 is larger than the wall-mounted support 30, the width (b) and length (a) of the opening 131 in this embodiment are both 480-520 mm. This means the length and width of the opening 14 are also 480-520 mm. This size setting ensures that the opening 131 is larger than the wall-mounted support 30, preventing collision between the wall-mounted support 30 and the sidewall of the opening 131 during lifting by the lifting mechanism 20. It also prevents the opening 131 from being too large and affecting the structural strength of the platform plate 13. Furthermore, the opening 131 is designed to be the same size as the opening 14, avoiding an excessively large opening 14 that would be too heavy to open or close.

[0042] Further, please refer to Figure 8 In this embodiment, the width b and length a of the opening 131 are different. Furthermore, the width b is smaller than the length a. Specifically, in this embodiment, the length a of the opening 131 is set to 520 mm, and the width b is set to 500 mm. Further, the direction of the length a of the opening 131 corresponds to the width direction of the platform plate 13, and the direction of the width b of the opening 131 corresponds to the length direction of the platform plate 13.

[0043] The following describes the use of the attached lifting scaffolding system 100 in this embodiment:

[0044] (1) The attached lifting scaffolding system 100 is installed on the outside of the floor and is used for construction on the fourth floor (4F). Figure 1 The image shows the unconstructed fourth floor, 4F.

[0045] (2) After the construction of the fourth floor (4F) is completed, as follows Figure 2 As shown, the frame body 10 is lifted using a lifting device, such as the lifting device described in publication number "CN105735629B". When the frame body 10 is lifted away from the wall-mounted support 30 on the first floor (1F), the guide rail of the frame body 10 disengages from the wall-mounted support 30 located at the lowest point on the first floor (1F). The wall-mounted support 30 located on the first floor (1F) is then removed. Figure 3 As shown;

[0046] (3) Place the disassembled wall-mounted support 30 on the platform plate 13 as follows: Figure 4 Therefore, the frame body 10 is lifted by the lifting device to the corresponding upper floor to be constructed, namely the fifth floor, 5F.

[0047] (4) Open the switch door 14 at the platform 13 on floors 2-6, and use the lifting mechanism 30 to lift the wall-mounted support 30 to the floor to be installed, such as... Figure 5 As shown;

[0048] (5) Install the raised wall-mounted support 30, such as Figure 6 As shown.

[0049] Similarly, after each floor is completed, the same steps can be used to lift the lowest wall-mounted support 30.

[0050] The aforementioned attached lifting scaffolding system 100, by providing an opening 131 on the platform plate 13 and a corresponding rotatable opening and closing door 14, allows for rapid lifting of the wall-mounted support 30 after disassembly, via the lifting mechanism 20. This saves time and effort compared to manual climbing of stairs, improving construction efficiency. Furthermore, the timely lifting of the wall-mounted support 30 allows for prompt installation on the uppermost existing floor, preventing scaffolding from falling. The newly added lifting mechanism 20 can also lift other components, such as triangular pieces for balcony installations and wall-mounted hanging brackets, demonstrating high practicality.

[0051] Although the present invention has been disclosed through the above embodiments, the scope of the present invention is not limited thereto. Without departing from the concept of the present invention, the above components can be replaced by similar or equivalent elements known to those skilled in the art.
