[0027] The technical solution of this utility model will now be clearly and completely described with reference to the accompanying drawings and embodiments. Obviously, the described embodiments are only some embodiments, not all embodiments. Based on this embodiment, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0028] Reference Figures 1 to 5 This embodiment provides a reusable opening sealing device, including a sealing plate 1, bolts 2, and a fixing device 3. The sealing plate 1 includes a sealing plate body 1.1, on which a first bolt hole 1.2 is provided. The fixing device 3 includes a bolt sleeve 3.1, a movable plate 3.2, and a movable plate support 3.3. The bolt sleeve 3.1 has a connecting thread and can be threadedly connected to the bolt 2. The movable plate support 3.3 is located at the bottom side of the bolt sleeve 3.1 and is symmetrically arranged. One end of the movable plate 3.2 is hinged between the movable plate supports 3.3 and is in a horizontal state after being unfolded. The bolt 2 passes through the first bolt hole 1.2 of the sealing plate 1 and is connected to the bolt sleeve 3.1 of the fixing device 3.

[0029] Specifically, the sealing plate body 1.1 is rectangular, and the first bolt holes 1.2 are arranged in an array.

[0030] Specifically, a first washer 2.1 is provided between the bolt 2 and the sealing plate 1.

[0031] Specifically, the movable plate 3.2 is L-shaped, and one end of the movable plate 3.2 is hinged to the movable plate support 3.3 by a pin.

[0032] Reference Figure 6 , Figure 7 and Figure 8 This embodiment also includes a sealing splicing plate 5 and splicing bolts 6. The sealing plate 1 is assembled and connected by the sealing splicing plate 5 and splicing bolts 6, which is suitable for situations where the construction opening of the structural floor slab 4 is too large and a single sealing plate 1 cannot seal it.

[0033] Specifically, the sealing splicing plate 5 includes a sealing splicing plate body 5.1, on which a second bolt hole 5.2 is provided; the sealing splicing plate body 5.1 is rectangular, and the second bolt holes 5.2 are arranged in an array, corresponding to the first bolt holes 1.2 on the sealing plate body 1.1.

[0034] Specifically, the splicing bolt 6 passes through the second washer 6.1 and the second bolt hole 5.2 and is connected to the nut 6.2.

[0035] Working principle:

[0036] Cover the construction opening of the structural floor slab 4 with the sealing plate 1, and fix the sealing plate 1 with bolts 2 and fixers 3 on both sides respectively: the fixer 3 opens the movable plate 3.2 to abut the bottom edge of the structural floor slab 4, and the bolts 2 are screwed into the bolt sleeve 3.1 through the threaded connection until the structural floor slab 4 is clamped.

[0037] When the construction opening in the structural floor slab 4 is too large for a single sealing plate 1 to seal, multiple sealing plates 1 are spliced ​​together using a sealing splicing plate 5 and splicing bolts 6. First, place two sealing plates 1 side by side for comparison. Then, place the sealing splicing plate 5 between the two sealing plates 1 and align the second bolt hole 5.2 with the first bolt hole 1.2. Next, align the splicing bolt 6 with the second bolt hole 5.2 and the first bolt hole 1.2 and screw it in. Finally, screw the nut 6.2 into the end of the splicing bolt 6 to secure it.
