Problems solved by technology

[0004] However, due to the long final setting time of the existing polymer mortar, it takes a long time for the polymer mortar to be applied to the building wall. It can be solidified, thus affecting the reinforcement of building walls

Embodiment 1-4

[0042] This embodiment discloses a polymer mortar reinforcement method for wall steel strand mesh, including the following steps:

[0043] (1) Preparation of mesh: use steel strands to prepare steel strand mesh according to the size of the site;

[0044] (2) Base treatment: eradicate the degraded concrete parts such as spalling, loosening and corrosion on the surface of the wall that need to be reinforced, expose the concrete structure layer, and repair the surface of the wall with cement mortar;

[0045] (3) Install and fix the mesh: drive anchor bolts on the end side of the base layer, and fix the edge of the mesh through the pull ring. After the pull ring is installed at the end of the steel strand, check carefully. If it is loose or falls off, it must be replaced. After the steel strand mesh is stretched to the pre-tightened (steel strand tensioned) state, the reinforcing member is installed, and the anchor bolt on the other side is fixed;

[0046] (4) Apply interface age...

Embodiment 5

[0054] The difference from Example 4 is that 120kg of calcium aluminate cement and 29kg of polyacrylamide were mixed evenly in advance, and then added to step (5) and mixed evenly with other components.

Embodiment 6

[0056] The difference from Example 4 is that 220kg of calcium aluminate cement and 16kg of polyacrylamide were mixed uniformly in advance, and then added to step (5) and mixed uniformly with other components.

Abstract

The invention relates to the field of concrete mortar, and particularly discloses a wall steel strand mesh polymer mortar reinforcing method. The method comprises the following steps: (1) weaving a mesh; (2) treating a base layer; (3) mounting a fixed mesh; (4) smearing an adhesion agent; (5) smearing polymer mortar; and (6) maintaining the polymer mortar. The polymer mortar is prepared in advance between the step (4) and the step (5) and comprises the following components in parts by weight: 356-590 parts of sand; 252-361 parts of Portland cement; 85-120 parts of an acrylic acid-2-acrylamide-2-methyl propane sulfonic acid copolymer; 19-30 parts of hydroxy propyl distarch phosphate; 4-12 parts of sodium tripolyphosphate; 1-5 parts of a defoaming agent; 5-9 parts of a water reducing agent; and 100-150 parts of water. The method has the effect of shortening the final setting time of the polymer mortar.

Description

technical field [0001] The present application relates to the technical field of concrete mortar, more specifically, it relates to a method for reinforcing steel strand mesh polymer mortar for walls. Background technique [0002] In order to prolong the service life of the building, it is often necessary to reinforce the body of wall of the building. Therefore, there is a need for a method for reinforcing and transforming the retained components under the condition that the appearance of the building remains unchanged and the appearance of the original components is maintained. [0003] At present, the steel strand mesh polymer mortar reinforcement method is generally used to reinforce the wall of the building. [0004] However, due to the long final setting time of the existing polymer mortar, after the polymer mortar is applied to the building wall, it takes a long time for the polymer mortar to solidify, thereby affecting the reinforcement of the building wall.
