[0031] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this utility model, not all of them. Therefore, the following detailed description of the embodiments of this utility model provided in the accompanying drawings is not intended to limit the scope of the claimed utility model, but merely to represent selected embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without inventive effort are within the scope of protection of this utility model.

[0032] This embodiment fixes the device to the floor slab, allowing for the assembly of multiple hoists mounted on tripods above the floor. The hoisting chains pass through the floor slab to the ground below, connecting to shackles. These shackles are evenly distributed on both sides of a support plate. Two formwork steel keels are then inserted simultaneously into two oppositely positioned shackles, forming multiple support structures. A large support plate is installed on these multiple support structures, facilitating worker standing and transporting construction materials and tools. Finally, the hoists allow the support plate to move up and down, providing support during floor slab reinforcement and renovation. Furthermore, the device is easy to assemble and disassemble, allowing for rapid installation and use at designated locations as needed, and significantly increasing the working space below the floor slab. Specific implementation details are as follows:

[0033] like Figures 1 to 6As shown, a support device for floor slab reinforcement and renovation construction includes a tripod 2, a hoist 3, and a support plate 5. The support plate 5 is set on the ground directly below the floor slab 1. Several tripods 2 are set on the top of the floor slab 1. A hoist 3 is connected directly below each tripod 2. The hoisting chain 4 at the bottom of each hoist 3 passes through the floor slab 1 and is connected to a shackle 14. Several shackles 14 are evenly distributed on both sides of the support plate 5, and two template steel keels 15 are inserted and connected to two opposite shackles 14. The support plate 5 is detachably set directly above several template steel keels 15. The device is fixed on the floor slab 1. Multiple hoists 3 installed on the tripod 2 can be assembled above the floor slab 1. The hoisting chain 4 of the hoist 3 passes through the floor slab 1 to the ground below and connects to the shackle 14. The chain 4 can be evenly distributed on both sides of the support plate 5. Then, two template steel keels 15 are inserted into the two oppositely arranged shackles 14 to form multiple sets of support structures. The large support plate 5 is connected to and supported by multiple sets of support structures, which makes it convenient for workers to stand or transport construction materials and tools. Finally, under the action of the hoist 3, the support plate 5 can be hoisted and moved up and down, playing a supporting role in the reinforcement and renovation of the floor slab 1. At the same time, the device is easy to assemble and disassemble, and can be quickly installed and put into use at a designated location as needed, which greatly increases the working space below the floor slab 1.

[0034] The tripod 2 includes three telescopic support rods 7, a load-bearing plate 8, and a lifting ring 9. The three telescopic support rods 7 are hinged to the bottom of the load-bearing plate 8, and the lifting ring 9 is connected to the center of the bottom of the load-bearing plate 8. A hoisting hoist 3 is hung on the lifting ring 9. The tripod 2 can improve the support capacity of the hoisting hoist 3. All three telescopic support rods 7 are telescopic and adjustable, which facilitates their installation in a suitable position and controls the vertical height of the hoisting hoist 3.

[0035] The hoist 3 has a chain 4 extending downwards and passing through a hoisting opening 6 in the floor slab 1. The bottom end of the chain 4 is connected to a hook 13, which is movably connected to the top of the shackle 14. Multiple hoisting openings 6 are provided in the floor slab 1 to facilitate the operation of the two hoisting hoists 3 on the tripod above the floor slab 1.

[0036] The template steel keel 15 has several fixing holes 16. The template steel keel 15 is connected to the support plate 5 through the fixing holes 16 and fixing bolts that are adapted to the fixing holes 16. By setting multiple fixing holes 16 on the template steel keel 15, the connection and fixation between the template steel keel 15 and the support plate 5 can be strengthened through the fixing holes 16 when the template steel keel 15 supports the support plate 5, thereby improving the overall stability of the support plate 5.

[0037] A pressure-bearing reinforcing plate 19 is installed on the support plate 5, and an anti-slip layer 20 is formed on the upper surface of the pressure-bearing reinforcing plate 19. By setting the pressure-bearing reinforcing plate 19 in the support plate 5, its pressure-bearing capacity can be improved, making it less prone to damage and breakage, and facilitating safe operation for workers. At the same time, the anti-slip layer 20 can improve the anti-slip ability of the support plate 5, making it less likely to slip during the transport of people or goods.

[0038] A safety warning component is installed on the support plate 5, comprising a gravity sensor 17 and an alarm 18. Both the gravity sensor 17 and the alarm 18 are located within the support plate 5. The sensing end of the gravity sensor 17 is connected to the top of the support plate 5, and the alarm 18 is electrically connected to the gravity sensor 17. Through this safety warning component within the support plate 5, the load above the support plate 5 can be monitored under the action of the gravity sensor 17. When the load reaches a warning value, the alarm 18 will sound an alarm, allowing staff to make timely adjustments and prevent accidents, thus further improving the safety of the device.

[0039] The support plate 5 is made of stainless steel, and the template steel keel 15 is made of galvanized steel pipe.

[0040] The telescopic support rod 7 has an adjustment and fixing hole 10 in the middle, and a limiting bolt for fixing the length of the telescopic support rod 7 is provided on the adjustment and fixing hole 10. The length of the telescopic support rod 7 can be easily adjusted and fixed by adjusting the fixing hole 10.

[0041] The bottom of the telescopic support rod 7 is provided with a mounting base plate 11, on which a plurality of mounting holes 12 are formed. The mounting base plate 11 and the mounting holes 12 facilitate the fixing of the tripod 2 to the floor slab 1.

[0042] The outer surface of the support plate 5 is coated with a wear-resistant coating. This coating improves the wear resistance of the outer surface of the support plate 5, significantly reduces wear during transport, and enhances durability.

[0043] Working Principle: The device is fixed to the floor slab. Multiple hoists mounted on tripods can be assembled above the floor slab. The hoisting chains pass through the floor slab to the ground below, connecting to shackles. These shackles can be evenly distributed on both sides of the support plate. Then, two formwork steel keels are simultaneously inserted into two oppositely positioned shackles, forming multiple support structures. A large support plate is installed on these multiple support structures for easy standing or transporting of construction materials and tools. Finally, the hoists can move the support plate up and down, providing support during floor slab reinforcement and renovation. The device is also easy to assemble and disassemble, allowing for rapid relocation to designated locations as needed. The installation and commissioning of the system has significantly increased the working space under the floor slab. The safety warning components installed within the support plate monitor the load above the support plate using a gravity sensor. When the load reaches a warning value, an alarm sounds, allowing staff to make timely adjustments and prevent accidents, thus further enhancing the safety of the device. The pressure-bearing reinforcing plates installed within the support plate increase its load-bearing capacity, making it less prone to damage and breakage, facilitating safer work for staff. Multiple fixing holes on the formwork steel keel strengthen the connection and fixation between the formwork steel keel and the support plate when the keel is supporting it, improving the overall stability of the support plate.

[0044] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
