Description
Technical Field
The invention belongs to the field of building art, and particularly relates to a method for restoring a recent stone wall surface to the ancient.
Background
A plurality of stone-built buildings are reserved in various places of China, and some buildings have a history of hundreds to thousands of years, and the wall surfaces of the stone-built buildings are subjected to wind, rain and sunshine for a long time, and are mostly dull in color, relatively smooth in surface and unclear in edges and corners. However, some stone-built historic buildings are not protected for a long time, the wall body cracks and collapses, and collapsed stones are transported away by surrounding villagers to cover a new house, so that the stone-built historic buildings are damaged. With the development of the modern tourism industry, people have stronger and stronger consciousness on protecting ancient buildings, and certain damaged stone-built ancient buildings begin to be repaired. However, the newly mined stone is selected for repair, the surface is fresh, or cement mortar is used for bonding and pointing, and the newly built part and the residual part are not very harmonious in terms of gloss and form. Hitherto, no method for retro of a newly-laid stone wall surface has been known, and therefore, it is necessary to carry out retro transformation of a newly-laid masonry portion so as to harmonize it with a residual portion.
Disclosure of Invention
The invention aims to overcome the defects of the prior art, provides a method for restoring a recent stone wall surface to the ancient, and solves the problems in the background art.
The technical scheme adopted by the invention for solving the technical problems is as follows: the method for retro of the newly-laid stone wall surface comprises the following steps:
(1) chiseling cement mortar joints of recent stone wall surfaces: chiseling a pointing along a cement mortar joint of a recent stone wall surface, wherein the chiseling depth is 2-3 cm;
(2) accelerating the physical weathering of the wall surface:
①, high-temperature treatment, namely baking the newly built wall surface block by using flame to enable the temperature to reach 600-800 ℃, and controlling the baking time to be 1-3 min;
② low temperature treatment, namely immediately coating liquid nitrogen on the wall surface after baking to rapidly reduce the temperature of the wall surface;
repeating ① and ② 3 to 5 cycles of the step (2) to accelerate the physical weathering of the wall surface until the edges and corners of the stone blocks and the rough parts disappear, the uneven parts become mild, the surface is smooth and the color is dark;
(3) polishing the wall surface: further grinding off edges and roughness after weathering;
(4) accelerating chemical weathering of the wall surface: smearing an acid solution on the polished wall surface, standing for 20-40 min after smearing, then cleaning with high-pressure tap water, and circulating for 2-3 times;
(5) manufacturing a new pointing: taking a fine soil mass on the ground surface around the historic building, removing gravels with the particle size larger than 0.5cm, and mixing tap water and a bonding auxiliary agent to prepare slurry, wherein the weight ratio of the soil mass to the tap water is 2-3: 1; after fully stirring and uniformly mixing, smearing the slurry on the chiseled pointing part to form a new pointing;
(6) and (3) planting moss: and planting moss at the new pointing part, and watering for maintenance.
In a preferred embodiment of the present invention, in the step (3), the wall surface is polished by sand paper.
In a preferred embodiment of the present invention, the acid solution in the step (4) is diluted hydrochloric acid with a concentration of 10% and diluted nitric acid with a concentration of 10%.
In a preferred embodiment of the present invention, the weight ratio of the soil body to the tap water in the step (5) is 2: 1.
In a preferred embodiment of the present invention, the bonding aid in step (5) is a water glass solution, wherein the weight ratio of the water-soil mixture to the water glass solution is 3: 1.
In a preferred embodiment of the present invention, in the step (5), the slurry is applied to the chiseled pointing part, and the adherend is uniformly applied by a spatula, and the surface is smooth.
In a preferred embodiment of the present invention, the cement mortar joints of the newly-built stone wall surface are removed by using a chisel or impact drilling in the step (1)
Compared with the background technology, the technical scheme has the following advantages:
the method is simple and convenient to implement and high in operability, the wall surface is promoted to quickly generate physical weathering by high-temperature and low-temperature circulation, the wall surface is promoted to quickly generate chemical weathering by dilute hydrochloric acid and dilute nitric acid, some carbonate minerals are reacted, and edges and roughness of the wall surface disappear by the two kinds of weathering, so that the wall surface is smooth in surface and dark in color; the cement mortar is subjected to pointing and chiseling, and is filled with an adhesive taking clay as a main component, and the main component and the color of the adhesive are similar to those of ancient buildings; the new jointing can be further coordinated with the jointing of the ancient building by utilizing the planted moss.
Detailed Description
The stone ancient building in a certain area is located in the southeast coastal area of China, and the ancient building belongs to a local financial owner according to data records, and the ancient building is mainly used for protecting personal private property, and has more than 570 years of history. As the ancient times are relatively long, the large area of the urban door and the wall body on one side of the ancient building collapses, most of the stones are lost, in order to reproduce the historical mining of the ancient building in the current year, the construction units related to the organization of units such as local government, tourist bureau and the like repair the ancient building, the wall body is built by fresh stones mined from surrounding mines, and the size and the shape of the selected stones are basically the same as those of the original ancient building. However, the newly built wall is obviously different from the previously built wall in color and luster, and is very inconsistent in appearance. The method provided by the invention is adopted to carry out retro on the newly-built wall.
(1) Chiseling cement mortar joints of recent stone wall surfaces: firstly, chiseling a part of a cement mortar joint of a newly-built wall by using a percussion drill, wherein the chiseling depth is 2 cm;
(2) ①, rapidly coating liquid nitrogen on ② to enable the surface of the stone block to generate physical weathering;
(3) polishing the weathered edges and roughness by using sand paper;
(4) accelerating chemical weathering of the wall surface: preparing 10% dilute hydrochloric acid and 10% dilute nitric acid, respectively coating on the surface of the rock, standing for 30min, cleaning off some carbonate minerals by using high-pressure tap water, coating the acid liquor with the above concentration, standing for reaction, and cleaning and washing;
(5) taking 100kg of clay at the periphery of the historic building, removing gravels with the particle size larger than 0.5cm, putting the clay into a stirrer, adding 50kg of tap water, fully and uniformly stirring, preparing slurry, adding 50kg of water glass solution, further uniformly stirring, preparing an adhesive, smearing the adhesive in the middle of the chiseled pointing by using a spatula, and leveling; the water glass solution is purchased from the market, and the density of the common water glass is 1.36-1.50 g/cm3, which is equivalent to Baume degree 38.4-48.3;
(6) and planting moss on the new pointing, and watering for maintenance.
After a period of time, the pointing is basically the same as that of the ancient building, and the color and the shape of the newly-built wall surface are also basically the same as those of the ancient building. By utilizing the method provided by the invention, the ancient ways treatment is successfully carried out on the newly built wall surface of the ancient building.
The above description is only a preferred embodiment of the present invention, and therefore should not be taken as limiting the scope of the invention, which is defined by the appended claims and their equivalents.
