[0002] After the completion of an existing building, due to a change in function, it is necessary to add a steel ladder in the basement to meet the function of fire evacuation. At present, when tiling the surface of the steel ladder, cement mortar is generally used to directly paste bricks on the base of the steel ladder surface. In this way, after the rust on the surface of the steel ladder is removed, the surface of the steel ladder is smooth and the adhesion between the steel ladder and the cement mortar is poor. It is very easy to produce problems such as poor self-stability and easy falling off during brick paving construction.

[0003] The hardening process of cement mortar base will produce large shrinkage deformation, which greatly weakens the fastening force between cement mortar and steel ladder, resulting in hollowing between the surface of steel ladder and cement mortar; and the steel ladder is in an environment with high temperature and humidity, with a certain degree of temperature difference, which is prone to thermal expansion and contraction. Due to the large difference in thermal expansion coefficient between the surface of steel ladder and the base cement mortar, bricks may peel off during the use of steel ladder, resulting in project repair, Utility Model Content
