[0029] The technical solution of this utility model will be further described in detail below with reference to the accompanying drawings and embodiments. The description of exemplary embodiments is merely illustrative and is in no way intended to limit this disclosure or its application or use. This disclosure may be implemented in many different forms and is not limited to the embodiments described herein. These embodiments are provided so that this disclosure will be thorough and complete, and will fully express the scope of this disclosure to those skilled in the art.

[0030] like Figures 1 to 3 As shown, this utility model provides a fixing device for the front beam of a suspended platform where it is impossible to erect a front support leg. It includes a rectangular fixing frame 2 and an H-shaped clamping frame 3. The rectangular fixing frame 2 is installed with its opening facing downwards on the top of the parapet wall 8 of the building. The bottom plates extending outwards on both sides are fixedly connected to the top of the parapet wall 8 by connecting bolts 4. The rectangular fixing frame 2 and the top of the parapet wall 8 form an open cavity, through which the front end of the suspended platform front beam 1 passes and extends outwards. The H-shaped clamping frame 3 is installed inside the open cavity. The waist plate of the H-shaped clamping frame 3 is clamped to the top surface of the suspended platform front beam 1, and the wing plate is clamped to the side surface of the suspended platform front beam 1. The connecting bolts 4 are pre-embedded bolts or expansion bolts.

[0031] The width of the H-shaped clamping frame 3 is the same as the width of the orifice-shaped cavity, and the height of the H-shaped clamping frame 3 is less than the height of the orifice-shaped cavity. The fixing device also includes fastening bolts 5 arranged laterally between the side plates of the shaped fixing frame 2 and the wing plates of the H-shaped clamping frame 3 to achieve a fastening connection between the H-shaped clamping frame and the shaped fixing frame, so that the H-shaped clamping frame is fixedly pressed against the top surface of the shaped fixing frame. In some embodiments, the fastening bolts 5 include two bolts symmetrically arranged between each side plate of the fixing frame and the wing plate of the adjacent H-shaped clamping frame 3. In other embodiments, the fastening bolt 5 is a single bolt that passes laterally through both sides of the shaped fixing frame 2, and the middle of the fastening bolt 5 passes through the portion of the wing plate of the H-shaped clamping frame 3 located above the waist plate.

[0032] During implementation, the wing plate of the H-shaped clamping frame 3 is partially cut off at the upper part of the waist plate to form a U-shaped structure with the opening facing downward. The front beam 1 of the suspended basket passes through the U-shaped structure, which facilitates spatial arrangement, reduces the weight of the H-shaped clamping frame 3, and facilitates on-site construction.

[0033] In some preferred embodiments, the front beam fixing device of the suspended platform further includes a clamping screw 7 vertically arranged on the top plate of the L-shaped fixing frame 2. The front end of the clamping screw 7 extends downward and presses against the top of the H-shaped clamping frame 3. The top plate of the L-shaped fixing frame 2 is provided with a nut that meshes with the clamping screw 7. By using the clamping screw 7, the H-shaped clamping frame 3 can be quickly clamped and positioned, which facilitates the insertion of fastening bolts 5 and ensures continuous clamping and positioning of the front beam 1 of the suspended platform during use.

[0034] In some preferred embodiments, the front beam fixing device of the suspended platform further includes a pad 6 disposed between the top of the parapet wall 8 and the bottom plate of the U-shaped fixing frame 2, and the connecting bolt 4 passes through the pad 6 and is fixedly connected to the top of the parapet wall 8. Specifically, the pad 6 is a U-shaped plate, and the inner cavity width of the U-shaped plate is the same as the width of the parapet wall 8 and is fitted onto the top of the parapet wall 8.

[0035] Furthermore, a specific embodiment of a fixing device for the front beam of a suspended platform is provided. This device can effectively meet the requirements for setting up suspended platforms in special locations and ensure the safety of exterior wall construction.

[0036] In a specific embodiment, the fixing device for the front beam of the suspended platform without front outriggers uses a 50mm inner width galvanized steel plate (with bolt holes) as a galvanized steel plate (with bolt holes) as an H-shaped fixing frame 2, and a 50mm outer width H-shaped galvanized steel plate (with bolt holes) as an H-shaped clamping frame 3. Grade 8.8 high-strength bolts are used as fastening bolts 5.

[0037] The specific construction method for fixing the front beam of a suspended platform without front outriggers during the construction process.

[0038] Step 1: Install the suspended platform according to the instruction manual, removing the front outriggers;

[0039] Step 2: Adjust the height of the suspended platform to meet the requirements of the instruction manual, so that the front beam 1 of the suspended platform rests on the parapet wall 8. The gap between the suspended platform and the parapet wall 8 is raised by using wooden blocks, steel plates as pads 6, etc., to ensure that the front is higher than the back, and the horizontal height difference between the front and back is controlled within 2% of the length of the crossbeam.

[0040] Step 3: Insert the H-shaped galvanized steel sheet and the geometric galvanized steel sheet from the upper part of the front beam rectangular tube;

[0041] Step 4: Secure the galvanized steel sheet using pre-embedded bolts or expansion bolts;

[0042] Step 5: Adjust the H-shaped galvanized steel plate up and down, and fix it with 8.8 grade high-strength bolts as fastening bolts 5;

[0043] Step 6: Acceptance of the suspended platform.

[0044] For construction situations where suspended platforms cannot be erected in special locations of buildings, this utility model provides a fixing device for the front beam of a suspended platform where front outriggers cannot be erected. This device can be fixed to the parapet wall 8 or the main structure, eliminating the need for front outriggers while still meeting the technical requirements for the suspended platform's anti-overturning capability. The provided front beam fixing device solves the need for erecting suspended platforms in special locations, meets the anti-overturning requirements, ensures the safety of on-site suspended platform construction, and has certain economic and social benefits.

[0045] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and not to limit it; although the utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications can still be made to the specific implementation of this utility model or equivalent substitutions can be made to some technical features without departing from the spirit of the technical solution of this utility model, and all such modifications and substitutions should be covered within the scope of the technical solution claimed by this utility model.
