[0002] During the process of filling mortar, construction workers are unable to accurately grasp the filling thickness of the waterproof mortar, resulting in insufficient filling thickness of the waterproof mortar and insufficient density causing mortar cracking and perforation, affecting the construction quality. Therefore, it is necessary to strictly control the filling thickness and density of the waterproof mortar to achieve the filling size required by the construction. Summary of the invention

[0003] In view of the above problems existing in the prior art, an object of the present invention is to provide a controller capable of controlling the filling thickness and a construction method thereof.

[0004] The present invention provides the following technical solution: a controller for filling mortar thickness, characterized by comprising a pasting plate, a handle, a plugging screw and a rubber ring, wherein the handle is fixedly mounted on the outer end surface of the pasting plate, and the inner end surface of the pasting plate is fixedly connected to the plugging screw via a rubber ring;

[0005] The rubber ring is a truncated cone structure with a through hole inside. The end of the rubber ring with a smaller cross-sectional diameter is sleeve-connected with the plugging screw, and the end of the rubber ring with a larger cross-sectional diameter is adsorbed and fixed on the inner end surface of the plate.

[0006] The controller for filling mortar thickness is characterized in that the flatness deviation of the inner end surface of the pasting plate is less than 0.10 mm, the roughness is less than 12.5, and the thickness of the pasting plate is 10 mm.

It is strictly forbidden to use a knife to cut the foam that overflows the hole.

[0018] 8) Inspection of sealing mortar: After the foaming agent is extruded, check whether the outer sealing mortar is damaged by extrusion. If there is no damage, fill the inner side of the outer wall with waterproof mortar, squeeze it tightly, and water it for maintenance.

[0019] 9) Seal the screw holes with brush: Align the 110PVC sleeve with the sealed screw holes on the exterior wall of the structure, and use a fine-bristle brush to apply the sealing surface layer.

[0040] 4) Mix waterproof mortar: Mix according to the following dry material weight ratio: cement: sand: water: waterproof agent = 1:2:0.5:0.025. If the mortar mixing time exceeds 2 hours, it is strictly forbidden to continue filling and using;

[0041] 5) Filling mortar: After the first controller is fixed on the inner side of the main structure outer wall, the construction personnel use sandboards on the outdoor side to fill the hole with the prepared waterproof mortar 50mm deep, and squeeze while filling until it is filled to the same plane as the outer wall of the main structure, and smooth it with sandboards. Figure 2 ; Carry out watering three times a day for seven days, and check whether there is leakage during the maintenance process. If there is leakage, remove all of them, clean them up and refill them;

[0043] 7) Extrusion of foaming agent: After the foaming agent has formed a crust on its surface, use the end of the plugging screw (3) in the second controller to pressurize the foaming agent back in the hole to ensure that the connecting steel plate is flush with the structural wall. It is strictly forbidden to use a knife to cut the foaming agent that overflows the hole. Figure 3 .

[0044] 8) Inspection of sealing mortar: After the extrusion of the foaming agent is completed, check whether the outer sealing mortar is damaged by the extrusion when the foaming agent is applied. If there is no damage, fill the inner side of the outer wall with waterproof mortar, squeeze it densely, and water it three times a day for seven days.
