Description

Technical Field

[0001] This utility model relates to the field of building construction technology, specifically to a formwork support system for partial floor slabs at the edge of high-rise buildings. Background Technology

[0002] During the construction of high-rise main structures, gaps of a certain size are left at the edges due to the installation of equipment such as tower cranes attached to walls, elevators attached to walls, or integral lifting frames. These gaps need to be filled after the construction equipment is removed.

[0003] Existing equipment has the following drawbacks: Traditional construction methods for working near edges typically involve cantilevering I-beams on the floor below the corresponding edge location and erecting ordinary steel pipe scaffolding with couplers as a formwork platform and construction operation platform. The steel pipe platform is erected before construction and dismantled afterward. In high-rise building construction sites, different floor slabs may require multiple formwork operations. Each formwork erection and concrete pouring requires significant manpower and resources to dismantle and reassemble the formwork system and platform, which is not only inefficient but also increases construction costs. Furthermore, the lack of edge protection during the erection of cantilevered I-beams and steel pipe platforms at the edge poses a significant safety risk.

[0004] Therefore, this application proposes a formwork support system for partial floor slabs at the edge of high-rise buildings to solve the aforementioned problems. Utility Model Content

[0005] The purpose of this invention is to provide a formwork support system for partial floor slabs at the edge of high-rise buildings, in order to solve the problems mentioned above, which are not only inefficient but also increase construction costs and safety risks.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a formwork support system for partial floor slabs at the edge of high-rise buildings, comprising a frame, and further comprising: The walking unit, which can be raised and lowered on the side of the frame, is used to control the movement of the formwork system on the floor slab; The operating unit is adjustable and set on one side of the frame to provide operating space for construction workers; A support plate, mounted on the operating unit and moving up and down with the operating unit, is used to seal and support the bottom of the gap in the floor slab. A lifting unit, mounted on the frame and connected to the operating unit, is used to adjust the contact between the lower end of the pallet and the floor slab. A telescopic unit, disposed on the frame and connected to the operating unit, is used to control the distance between the operating unit and the frame; The counter-pressure support unit is vertically mounted on the side of the frame away from the operating unit and abuts against the floor slab and the roof slab to fix the installation position of the frame.

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0017] Please see Figure 1-7 This utility model provides a technical solution: a formwork support system for partial floor slabs at the edge of high-rise buildings, including a frame 2, and further including: a walking unit 31, which is liftably mounted on the side of the frame 2 and used to control the movement of the formwork support system on the floor slab 1; an operating unit 4, which is adjustable and mounted on one side of the frame 2 to provide operating space for construction personnel; a support plate 43, which is mounted on the operating unit 4 and moves up and down with the operating unit 4, and used to seal and support the bottom of the notch 101 on the floor slab 1; a lifting unit 5, which is mounted on the frame 2 and connected to the operating unit 4, and used to adjust the contact between the support plate 43 and the lower end of the floor slab 1; a telescopic unit 6, which is mounted on the frame 2 and connected to the operating unit 4, and used to control the distance between the operating unit 4 and the frame 2; and a counter-pressure support unit 7, which is liftably mounted on the side of the frame 2 away from the operating unit 4 and abuts between the floor slab 1 and the top plate 11, and used to fix the installation position of the frame 2.

[0018] It should be noted that during operation, when installing this formwork support system, first locate the gap 101 to be filled. As the walking unit 31 moves, it provides rolling support to the floor slab 1. Workers can walk on the floor slab 1 by pushing the frame 2, driven by the walking unit 31. Then, when the operating unit 4 is moved to the set position, the walking unit 31 is moved upwards, and the counter-pressure support unit 7 is adjusted to abut and fix between the floor slab 1 and the top plate 11, thus fixing the entire formwork support system to the floor slab 1. Then, the telescopic unit 6 is adjusted to move away from the counter-pressure support unit 7, extending the operating unit 4 to the outside of the floor slab 1, ensuring the entire operating unit 4 is completely outside the edge of the floor slab 1. After the operating unit 4 is in place, the telescopic unit 6 is locked. Then, the lifting unit 5 is adjusted to drive the operating unit 4 downwards, causing the support plate 43 to move below the floor slab 1. Then, the telescopic unit 6 is retracted, and when the operating unit 4 contacts the outside of the floor slab 1, the telescopic unit 6 is locked. Finally, the lifting unit 5 is adjusted... The support plate 43 is moved upward and placed against the bottom of the gap 101. Then, the lifting unit 5 is locked, and concrete is poured into the gap 101. Construction workers can stand on the operating unit 4 to fill the gap 101. The counter-pressure support unit 7 can be raised and lowered and set on the side of the frame 2 away from the operating unit 4, and abuts against the floor slab 1 and the top slab 11. It can firmly fix the installation position of the frame 2 and prevent the formwork system from shifting or shaking due to external forces during construction, further enhancing the safety of construction. Especially in dangerous environments such as high-rise buildings near edges, it provides a stable working platform for construction workers. The walking unit 31 can provide rolling support with the floor slab 1 when the frame 2 moves. When the frame 2 needs to be fixed, it moves upward so that the frame 2 is fixedly supported with the floor slab 1. This allows the formwork system to move and be fixed flexibly on the floor slab 1 without frequent disassembly and assembly, which greatly improves construction efficiency, reduces the consumption of manpower and material resources, and lowers construction costs and safety risks.

[0019] In one embodiment, the frame 2 includes: a base frame 21, a square frame structure designed to be movably disposed above the floor slab 1, for supporting the formwork support system; a column 25, fixed to the upper end of the base frame 21; a top frame 22, fixed to the upper end of the column 25, for supporting the telescopic unit 6; and a side lug 24, fixed to the side of the base frame 21, for mounting the walking unit 31.

[0020] This design is for reference. Figure 6The base frame 21 adopts a square frame structure design and can be movably installed above the floor slab 1. This structure has a large contact area, which can evenly distribute the pressure applied to the floor slab 1 by the formwork support system, effectively avoiding damage to the floor slab 1 caused by excessive local pressure. The column 25 is fixed to the upper end of the base frame 21, and the top frame 22 is fixed to the upper end of the column 25, forming a vertical support structure, which further enhances the overall rigidity and stability of the frame 2. The top frame 22 is used to support the telescopic unit 6. The top frame 22 can effectively withstand the force generated by the telescopic unit 6 during the adjustment process, ensuring the normal operation of the telescopic unit 6. The side lug 24 is fixed to the side of the base frame 21, providing a suitable installation position for the walking unit 31, so that the walking unit 31 can be tightly integrated with the frame 2, ensuring the stable operation of the walking unit 31.

[0021] In one embodiment, the walking unit 31 includes: a first screw 311 threadedly connected to the side lug 24 for adjusting the installation height of the walking unit 31; a wheel 313 disposed at the lower end of the first screw 311 for providing rolling support to the formwork support system; and a first turntable 312 disposed at the upper end of the first screw 311.

[0022] This design is for reference. Figure 6 ,as well as Figure 7 The first screw 311 is threaded onto the side lug 24. The surface of the floor slab 1 may be uneven. By rotating the first screw 311, the distance between the wheel 313 and the floor slab 1 can be easily adjusted to ensure that the formwork system remains horizontal. The wheel 313 is located at the lower end of the first screw 311, providing rolling support for the formwork system. Compared with the traditional fixed support method, the rolling support greatly reduces the friction of the formwork system during movement, allowing construction workers to easily move the formwork system between different positions. In high-rise building construction, it is often necessary to adjust the position of the formwork system to adapt to different construction needs. The rolling support function of the wheel 313 significantly improves the movement efficiency and saves manpower and time costs. After the formwork system is moved to the set position, rotating the first screw 311 drives the wheel 313 to move upward, separating the wheel 313 from the ground.

[0023] In one embodiment, the operating unit 4 includes: a protective frame 41, which has a square frame structure and is located on one side of the telescopic unit 6, for providing construction space for construction personnel; a lifting rod 42, which is fixed to the protective frame 41 on the side near the frame 2; and a support plate 43, which is fixed to the lifting rod 42 on the side near the frame 2.

[0024] This design is for reference. Figure 1-7The protective frame 41 adopts a square frame structure design and is located on one side of the telescopic unit 6, creating a relatively independent and enclosed construction space for construction personnel. When working near the edge of a high-rise building, this space can effectively prevent construction personnel from accidentally falling and also prevent external debris from falling and causing injury to personnel. The telescopic unit 6 can realize the raising and lowering of the lifting rod 42. When the lifting rod 42 drives the support plate 43 to abut against the notch 101, the telescopic unit 6 is fixed, completing the adjustment of the installation height of the support plate 43. Then, the workers stand inside the protective frame 41 to repair the notch 101. By setting up this device, the support plate 43 can be quickly adjusted to a suitable height, making it convenient for construction personnel to operate and reducing repetitive labor and time waste caused by unsuitable height.

[0025] In one embodiment, the telescopic unit 6 includes: a telescopic frame 61, which is mounted on the top frame 22 and fixedly connected to the top frame 22 by a first pin 23; and a fixed frame 62, which is disposed on one side of the telescopic frame 61 and is used to install the lifting rod 42, the lifting rod 42 being fixedly connected to the fixed frame 62 by a second pin 63.

[0026] This design is for reference. Figure 6 ,as well as Figure 7 The telescopic frame 61 is mounted on the top frame 22 and is fixedly connected to the positioning groove 2201 on the top frame 22 by the first pin 23. The first pin 23 can be inserted into different adjustment grooves 6101 to adjust the extension length of the telescopic frame 61 on the top frame 22, thereby adjusting the gap between the protective frame 41 and the floor slab 1.

[0027] In one embodiment, the lifting unit 5 includes: a third screw 51, which is threadedly connected to the telescopic frame 61 and threadedly connected to the connecting lug 44 fixed to the upper end of the lifting rod 42; and a third turntable 52, which is fixed to the top end of the third screw 51 and is used to drive the third screw 51 to rotate.

[0028] This design is for reference. Figure 5 The third screw 51 is threaded onto the telescopic frame 61 and threaded onto the connecting lug 44 fixed at the upper end of the lifting rod 42. By rotating the third turntable 52, the third screw 51 can be driven to rotate, thereby raising and lowering the lifting rod 42. After the lifting rod 42 is adjusted to a suitable height, the second pin 63 is inserted into the fixed frame 62 and fixed in the fixed groove 4201, thus completing the adjustment of the installation height of the protective frame 41.

[0029] In one embodiment, the counter-pressure support unit 7 includes: a fixed rod 71 with an open upper end and fixed to the top frame 22; a movable rod 72 that passes through the fixed rod 71 and is fixedly connected to the fixed rod 71 by a third pin 73; a rotating seat 75 that is rotatably disposed at the top end of the movable rod 72; a top clamping plate 74 disposed at the upper end of the rotating seat 75 and having a screw threadedly connected to the rotating seat 75 at its lower end, for abutting and fixing to the upper top plate 11; and an abutting plate 76 that is fixed to the lower end of the fixed rod 71 and abuts against the floor slab 1.

[0030] This design is for reference. Figure 6 ,as well as Figure 7 The abutment plate 76 is fixed to the lower end of the fixing rod 71 and abuts against the floor slab 1. The clamping plate 74 is set above the rotating seat 75 and abuts against the upper top plate 11. This double-layer abutment method constructs a stable support system, so that the frame 2 is stably fixed on the floor slab 1. First, by pulling the movable rod 72 out of the fixing rod 71, the abutment plate 76 is moved upward to make a rough adjustment of the installation height of the abutment plate 76. Then, the rotating seat 75 is rotated to drive the screw at the lower end of the abutment plate 76 to rotate, thereby driving the abutment plate 76 to move upward to make a fine adjustment of the abutment plate 76, so that the abutment plate 76 abuts against and is fixed on the top plate 11, thus completing the fixing of the frame 2. The components can work together to resist deformation and displacement, improving the stability and reliability of the entire structure.

The significance or implied number of the indicated technical features is not specified. Therefore, a feature defined with "first" or "second" may explicitly or implicitly include at least one of those features.
