Problems solved by technology

The first method is commonly used, and all the existing glazed exterior wall tiles and porcelain exterior wall facing bricks are constructed by this method; the second method is rarely used, especially on walls with a large amount of engineering. This is the case, because the second method is very time-consuming and labor-intensive, and in the current period of high wages, no construction team has adopted it.
The method of plastering and filling joints with gray boards obviously has the following shortcomings: the antique exterior wall facing brick of the ceramic body is non-glazed, and there are many pores, sand holes, and wire drawing on the surface, and the white cement paste is completely filled into all the pores of the facing brick. , the finish cannot be completely cleaned, causing the brick surface to change color, losing the texture and charm of the original brick; in addition, it also causes a lot of waste of cement paste and environmental pollution

Embodiment 1

[0041] Follow the steps below to carry out the pointing construction of the antique exterior wall facing brick of the ceramic body:

[0042] Step 1. Preparation of jointing agent: first weigh each component according to the following ratio:

[0043] External wall putty ash 50kg,

[0044] White cement 50 kg,

[0045] Polyvinyl acetate emulsion 4.5kg,

[0046] Clear water 21 kg;

[0047] Put the weighed white cement and exterior wall putty ash into a barrel-shaped container, and dry mix for 6 minutes to make the white cement and exterior wall putty ash mix evenly; pour clean water and polyvinyl acetate into another barrel-shaped container successively Emulsion, stir for 1 minute to form a dilution of polyvinyl acetate emulsion, then add the dilution to a barrel-shaped container filled with white cement and putty ash on the exterior wall, first use a shovel or stick to roughly stir for 1.5 minutes to make it uniform, and then Blend the mixture into a paste with an electric st...

Abstract

The invention discloses a ceramic facing brick special-purposed pointing agent comprising components of, by mass: 50-60 parts of exterior wall putty, 50-60 parts of white cement, 4-6 parts of polyvinyl acetate emulsion, and 20-24 parts of clear water. The polyvinyl acetate emulsion is a polymer with a polymerization degree between 250 and 600. Polyvinyl acetate is uniformly dispersed as particles with sizes of 0.1-2.0mum, such that the polyvinyl acetate emulsion is formed. Solid content of the polyvinyl acetate emulsion is 30-40%. The pointing agent is in a viscous stable agglomerated state, and can be injected into ceramic facing brick clearances requiring pointing by using a glue injection gun. The ceramic facing brick special-purposed pointing agent provide by the invention is advantaged in good workability, viscosity and economic property. The agent can be injected into ceramic facing brick clearances by using a special glue injection gun. Therefore, the contact of the pointing agent and the wall surface is greatly reduced. When the pointing agent is used in pointing ceramic-blank imitated antique exterior wall facing bricks, the ceramic-blank imitated antique exterior wall facing bricks are effectively prevented from being polluted, and construction efficiency is greatly improved.

Description

technical field [0001] The invention relates to the technical field of building construction, in particular to a special pointing agent for ceramic facing bricks and a pointing method for ceramic facing bricks realized by using the pointing agent. Background technique [0002] The method of building antique buildings and renovating old buildings by the method of ceramic body imitating the antique exterior wall facing bricks, although the time of appearance is not long, it is still in the ascendant. However, people have not paid attention to the awareness of the pollution of this kind of brick during construction, and the awareness of poor quality perception caused by improper construction of construction joints is also very low. According to reports, the first phase of the University City Museum project, the outer wall is 180 thick lime-sand bricks with ceramic bodies and antique exterior wall facing bricks, with an area of ​​25320m2 2 , One of the main reasons for the "une...
