Referring to fig. 1, the coil waterproof layer 20 is laid on the second leveling layer 103, and the second leveling layer 103 is arc-shaped in transition at the corner of the parapet 80, so as to provide an arc transition surface for the coil waterproof layer 20, and make the coil waterproof layer 20 not easy to bend.

Referring to fig. 2 and 3, the waterproof layer 20 of the coil is partially attached to the wall of the parapet wall 80, and the portion of the waterproof layer 20 of the coil attached to the parapet wall 80 is a vertical attachment portion. The additional waterproof layer 30 is partially attached to the vertical attaching portion, and the additional waterproof layer 30 is attached to the vertical attaching portion and is a vertical waterproof portion. The top of vertical waterproof portion and the top butt of vertical laminating portion are formed with grafting portion 100, have seted up positioning groove 90 on the parapet 80, and grafting portion 100 inserts and establishes in positioning groove 90. The positioning groove 90 is filled with a sealing paste 110, thereby fixing the socket 100 in the positioning groove 90. The second leveling layer 103 is coated at the notch of the positioning groove 90 of the parapet wall 80.

Referring to fig. 3, in order to improve the sealing property between the additional waterproof layer 30 and the parapet wall 80, a cement mortar layer 120 is attached to the parapet wall 80, the bottom end of the cement mortar layer 120 abuts against the insertion portion 100, and the surface of the cement mortar layer 120 facing away from the parapet wall 80 is flush with the surface of the additional waterproof layer 30 facing away from the parapet wall 80.

Referring to fig. 4, a threaded sleeve 50 is pre-installed on the parapet wall 80, and one end of the threaded sleeve 50 penetrates the parapet wall 80. After the cement mortar layer 120 is poured, one end of the threaded sleeve 50 penetrates through the cement mortar layer 120. The threaded sleeve 50 is threadedly connected with a fixing bolt 60, and one end of the fixing bolt 60 is inserted into the threaded sleeve 50.

Referring to fig. 4, a side of the cement mortar layer 120 facing away from the parapet wall 80 is attached with a pressing plate 70, and the pressing plate 70 is attached to both the cement mortar layer 120 and the additional waterproof layer 30. The fixing bolt 60 penetrates through the pressing plate 70, an inserting groove 130 is formed in one side, attached to the cement mortar layer 120, of the pressing plate 70, and one end of the threaded sleeve 50 is inserted into the inserting groove 130. The pressure plate 70 is provided with a receiving groove 140 on a side away from the cement mortar layer 120, the head of the fixing bolt 60 is inserted into the receiving groove 140, and the head of the fixing bolt 60 abuts against the pressure plate 70.

Referring to fig. 4 and 5, the upper surface of the pressing plate 70 is provided with a lifting groove 150, the bottom end of the lifting groove 150 is communicated with the accommodating groove 140, and a blocking plate 160 is vertically slidably disposed in the lifting groove 150. After the head of the fixing bolt 60 is inserted into the receiving groove 140, the blocking plate 160 is moved down, so that the blocking plate 160 blocks the head of the fixing bolt 60 in the receiving groove 140. The arrangement of the plugging plate 160 and the accommodating groove 140 achieves the effect of protecting the head of the fixing bolt 60, and reduces the possibility of rusting of the fixing bolt 60.
