[0002] The hanging formwork device used for floor slab pouring is a special formwork structure. It is used to provide a formwork suspension system without lower support when there is insufficient lower space or obstacles during the floor slab pouring process. The hanging formwork device is suspended in the air through various fixing methods, bearing the weight of concrete and pouring pressure to ensure the smooth pouring of the floor slab.

[0003] When using a hanging formwork device during floor slab pouring, it is necessary to lift the hanging formwork frame through a lifting device to support the concrete. Each time the hanging formwork frame is used, it needs to be connected to the steel cable of the lifting device through multiple connecting parts and then dismantled after use. The disassembly and assembly process is complicated and cumbersome, resulting in a decrease in the efficiency of floor slab pouring. Therefore, in response to the above problems, we propose a new type of hanging formwork device for floor slab pouring. Utility Model Content

[0021] Embodiment 1, as Figure 1-Figure 4 As shown, the utility model provides a hanging formwork device for pouring floor slabs, including a formwork frame 1, slots 21 are provided at the bottom of the formwork frame 1 near the four corners, plug plates 31 are inserted between the inner surface walls of the slots 21, the bottom of the plug plate 31 is fixedly connected with a connecting plate 32 extending outward, the top of the connecting plate 32 is located at a position away from the plug plate 31 and is fixedly connected with a mounting plate 33, the top of the mounting plate 33 is fixedly connected with a hanging ring 34, the outer surface of the mounting plate 33 is fitted with the outer surface of the formwork frame 1 near the corner, a mold groove 11 is provided at the top of the formwork frame 1, a mounting groove 2 is provided at the bottom of the formwork frame 1 located in the middle of the connecting plate 32, an electric push rod 3 is installed at the inner top of the mounting groove 2, and the telescopic end of the electric push rod 3 does not contact the top of the connecting plate 32.

[0022] The effect achieved by the entire embodiment 1 is that the lifting ring 34, the mounting plate 33, the connecting plate 32 and the plug plate 31 in the device form a connecting piece as a whole. When in use, after the four lifting rings 34 are connected and fixed with the ropes of the lifting equipment in advance, a suitable formwork 1 is selected, and then the plug plate 31 is inserted from bottom to top into the four slots 21 near the corners at the bottom of the formwork 1. During the insertion process, the mounting plate 33 needs to be kept in the direction of the outside of the formwork 1. After the connection between the plug plate 31 and the slot 21 is completed, the four connecting plates 32 will support the bottom of the formwork 1. Subsequently, the four lifting rings 34 are lifted to a suitable height for pouring the floor slab by the lifting equipment, and then the formwork 1 can complete the support operation for the concrete. When the pouring is completed and the formwork needs to be removed, the lifting device is used to lift the four lifting rings 34 to a suitable height for pouring the floor slab. The heavy equipment moves the formwork 1 to the lower bracket, and then starts the four electric push rods 3 to push the four connecting plates 32 downward. At this time, the plug plate 31 will move downward with the connecting plate 32 and disengage from the slot 21. The overall structure is simple, and the separate design allows for quick disassembly and assembly between the formwork 1 and the lifting equipment, greatly improving the efficiency of floor slab casting. The mold groove 11 is designed mainly for placing templates. By placing different templates inside the mold groove 11, floors of different shapes and sizes can be cast. The formwork 1 has a variety of sizes, which can be replaced according to actual usage. The formwork 1 needs to be placed on a matching bracket in advance for use, and the four corners of the formwork 1 need not be blocked by the bracket.

[0023] Embodiment 2, as Figure 1-Figure 4 As shown, a flange 4 is installed near the middle of the bottom of the mold frame 1, a circular sleeve 41 is welded to the bottom of the flange 4, the circular sleeve 41 and the mold frame 1 are arranged perpendicular to each other, the bottom of the circular sleeve 41 is threadedly connected to a threaded sleeve 42, the bottom of the threaded sleeve 42 is threadedly connected to a threaded rod 43, and a level ruler 44 is fixedly installed on the bottom of the threaded rod 43.

[0024] The effect achieved by the entire embodiment 2 is that, since the circular sleeve 41 and the formwork 1 are perpendicular, and the level 44 and the threaded rod 43 are perpendicular, the level 44 and the formwork 1 are in a parallel state, and the level 44 can effectively detect the horizontality through the bubble tubes in the horizontal and vertical directions. When the formwork 1 is hoisted to a suitable height for use during the floor pouring process, the horizontal state of the formwork 1 can be viewed through the level 44 at the bottom, and as needed, by rotating the threaded sleeve 42, the threaded sleeve 42 will move downward inside the circular sleeve 41, and by rotating the threaded rod 43, the threaded rod 43 will move downward inside the threaded sleeve 42, so that the height of the level 44 can be adjusted within a certain height range, so that the staff can directly judge the horizontality of the formwork 1 at a low place, thereby ensuring the pouring quality of the floor, and the flange 4 is mainly used to connect the circular sleeve 41 and the formwork 1, and can be removed as needed.

[0025] Working principle: When in use, after connecting and fixing the four lifting rings 34 with the ropes of the lifting equipment in advance, select a suitable formwork 1, and then insert the plug plate 31 from bottom to top into the four slots 21 near the corners at the bottom of the formwork 1. During the insertion process, it is necessary to keep the mounting plate 33 located outside the formwork 1. After the plug plate 31 and the slot 21 are connected, the four connecting plates 32 will support the bottom of the formwork 1. Then, the four lifting rings 34 are lifted to a suitable height for pouring the floor slab by the lifting equipment, and then the formwork 1 can complete the support operation for the concrete. When the pouring is completed and the formwork needs to be removed, the formwork 1 is moved to a lower bracket by the lifting equipment, and then the four electric push rods 3 are started to push the four connecting plates 32 downward. At this time, the plug plate 31 will follow As the connecting plate 32 moves downward and disengages from the slot 21, the overall structure is simple, and the separate design allows for quick disassembly and assembly between the formwork 1 and the lifting equipment, greatly improving the efficiency of floor slab casting. At the same time, when the formwork 1 is hoisted to a suitable height for use during floor slab casting, the horizontal state of the formwork 1 can be viewed through the level ruler 44 at the bottom, and as needed, by rotating the threaded sleeve 42, the threaded sleeve 42 will move downward inside the circular sleeve 41, and by rotating the threaded rod 43, the threaded rod 43 will move downward inside the threaded sleeve 42, so that the height of the level ruler 44 can be adjusted within a certain height range, so that the staff can directly judge the horizontality of the formwork 1 at a low place, thereby ensuring the casting quality of the floor slab.
