This problem is obviously a real problem that exists and is relatively difficult to solve. In view of this, in order to solve this technical problem, a mounting plate 3 and a connecting plate 4 are added to the application document.

[0027] More specifically:

[0028] like Figure 1-Figure 4 As shown:

[0029] In combination with the above content, a mounting plate 3 is installed on the surface of the prefabricated wall 2 by embedded bolts 5, and a third covering plate 16 with an L-shaped structure is welded and fixed to the surface of the mounting plate 3. A first covering plate 6 is installed on the side of the surface of the prefabricated wall 2 away from the mounting plate 3, and a second covering plate 8 is symmetrically arranged on the upper side of the prefabricated wall 2, and a number of connecting rods 9 are fixedly connected between the two groups of second covering plates 8 and between the first covering plate 6 and the third covering plate 16.

[0030] In this embodiment: when the device is in use, the mounting plate 3 is first installed by the embedded bolts 5 on the prefabricated wall 2, and one side of the prefabricated wall 2 is clamped by the third sealing plate 16 and the first sealing plate 6, and then the rotating rod 12 is rotated to drive the second sealing plates 8 on both sides to move toward the side of the floor 1, so that the second sealing plates 8 are pressed against the floor 1, and the joint is sealed by the second sealing plate 8, the third sealing plate 16 and the first sealing plate 6, and the position of the second sealing plate 8 can be adjusted according to the size of the joint, so as to facilitate the sealing of joints of different sizes.
