Description

Technical Field

[0001] The invention relates to the technical field of historical building repair, and in particular to a water-brushed stone shield-shaped coat of arms floral decoration repair method. Background Art

[0002] Water-brushed stone (Shanghai plaster), in Shanghai dialect, is called "Tai Shizi", and in other regions, it is called "Washed Stone" or "Water-washed Water-brushed Stone". The water-brushed stone facing in Shanghai's historical buildings developed with the introduction of cement (cement) and cement plastering (plaster, stucco, translated as "batch files" in Shanghai dialect) technology into China. Around 1910, modern forms of water-brushed stone facing appeared in Shanghai. For example, the ground floor of the Huizhong Hotel at No. 19 on the Bund, which was built from 1906 to 1908, used water-brushed stone facing. Judging from the effect of water-brushed stone, the stone selection, proportion, texture, corner details, etc. are all mature and exquisite. Water-brushed stone facing was quite popular in Shanghai's modern buildings in the 1920s and 1930s, especially in commercial and residential buildings. As a typical and prominent representative of the imitation stone plaster finishes of Shanghai's historical buildings, water-brushed stone largely reflects the characteristics of Shanghai's historical buildings in terms of finishing and decoration. It is one of the most common and representative important finishing types in Shanghai's historical architectural heritage, in addition to the plain brick wall finishes.

[0003] At present, when repairing some water-brushed stone decorations, it often happens that the degree of restoration of the repaired decorations is poor compared to the original decorations, and cracks often appear on the water-brushed stone surface. Summary of the invention

[0037] See also Figure 1 The method for repairing water-brushed stone shield-shaped coat of arms and floral decorations provided by the present invention comprises the following steps:

[0038] S1, construct the template based on the original coat of arms rosette.

[0039] It is understandable that the above steps may further include:

[0040] S101, obtaining the original shield-shaped coat of arms floral decoration's own parameters.

[0041] It is understandable that the intrinsic parameters may include parameters such as size and shape, and the parameters may come from some historical records.

[0042] S102, modeling based on its own parameters;

[0043] It can be understood that the established model is a three-dimensional solid model.

[0044] S103, constructing a template according to the modeling results.

[0045] It will be appreciated that the template constructed may be a positive template.

[0046] S2, the original shield-shaped coat of arms floral decoration is re-molded through a template to form a preliminary repair floral decoration.

[0047] It is understandable that the above steps can be further:

[0048] S201, reinforcement of the original shield-shaped coat of arms.

[0049] It is understandable that the reinforcement method can be to apply adhesive between the original shield-shaped coat of arms and the wall to which it is fixed, or to drill holes in the original shield-shaped coat of arms and reinforce it to the wall with stainless steel bolts.

[0050] S202, fix the template at the corresponding position of the original shield-shaped coat of arms.

[0051] It is understandable that the template can be fixed by stainless steel bolts or by some brackets.

[0052] S202a, measuring and positioning the original shield-shaped heraldic ornaments.

[0053] That is, coordinates can be established at a certain point of the original shield-shaped coat of arms decoration to achieve the positioning of each point on the original shield-shaped coat of arms decoration.

[0054] S202b, determining the fixed point corresponding to the template according to the position of the original shield-shaped coat of arms decoration.

[0055] Similarly, select the corresponding point on the template as the origin, and mark several points corresponding to the points marked on the original shield-shaped coat of arms.

[0056] S202c, fix the template correspondingly on the fixed point.

[0057] S203, pouring the formwork to form a preliminary repair decoration.

[0058] It is understandable that before pouring, the water-brushed stone finish on the original shield-shaped coat of arms decoration had basically fallen off. Therefore, before fixing the formwork, the surface of the original shield-shaped coat of arms decoration would be cleaned.

[0059] S3, paste the mesh cloth on the preliminary repair decoration.

[0060] It is understandable that by brushing adhesive on the preliminary repair decoration and bonding the mesh cloth to the preliminary repair decoration through the adhesive, the mesh cloth can effectively prevent the subsequent water-brushed stone veneer from cracking.

[0061] What you can know is that before doing the water-brushed stone veneer, you can first make a construction sample, that is, a small positive sample of the water-brushed stone. Subsequent production can refer to the sample to make the water-brushed stone veneer.

[0062] S4, apply water-brushed stone veneer on the preliminary repair decoration where the mesh cloth is located.

[0063] It is known that the above steps may further include:

[0064] S401, apply base slurry material on the preliminary repair decoration where the mesh cloth is located.

[0065] It is understandable that the base mortar on the preliminary repair decoration is cleaned: the loose soil on the preliminary repair decoration is cleaned and fully wetted with water. The base mortar material to be applied should be selected according to the type of preliminary repair decoration (the middle layer of plastering is usually divided into "soft base" and "hard base"). The commonly used hard base is 1:3 cement mortar, and the soft base is paper reinforced lime paste, yellow sand and cement. When applying the base mortar material, it is generally done from top to bottom. In this embodiment, a soft base can be used, and the thickness of the soft base can be selected to be about 12mm.

[0066] S402, prepare water-brushed stone raw materials according to the water-brushed stone blocks of the original shield-shaped coat of arms.

[0067] It is understandable that water-brushed stones can be collected on site, and the original proportions of stone, cement, and yellow sand can be analyzed, and repairs and restoration can be carried out according to the original proportions. The original stones can include dolomite, calcite, and granite, etc. The selection of the above-mentioned original stones should avoid weathered stone particles and should be rinsed clean when used. The origin, color, and texture of the colored stone slag should meet the design requirements.

[0068] S403, brushing the water-brushed stone material onto the preliminary repaired decoration where the mesh cloth is located to form a decorative surface.

[0069] It is understandable that in some cases where partitioning is required, the lines must be drawn or wooden strips must be nailed in, and the drawn lines must be based on the original wall compartment dimensions to ensure that the dimensions are exactly the same after repair.

[0070] Draw lines or glue and nail wooden strips to divide the grid according to the requirements of the drawings. The above-mentioned wooden strips should be made of red pine. They should be fully soaked in water before gluing. When gluing, use plain cement slurry to apply a 45° slope on both sides of the wooden strips. When gluing the wooden strips, pay attention to the fact that the vertical wooden strips should be glued on the same side of the vertical line to prevent random gluing left and right, which will cause uneven grid division. After the strips are glued, wait until the bottom layer of mortar is 70% to 80% dry before applying the surface layer of mortar, which is the water-brushed stone material.

[0071] S404, when the decorative surface is in a semi-solidified state, the decorative surface is processed so that the stones on the decorative surface are half exposed.

[0072] It is understandable that the water-brushed stone raw material should be applied after the base slurry material hardens. Generally, a thin layer of 1mm plain cement slurry is scraped first, and then the cement slag slurry is applied with a steel trowel. According to the particle size of the original stone, the cement slag slurry can be 8-12mm thick and 1:1 cement large slag overlay, 1:1.25 cement medium slag overlay or 1:1.5 cement small slag overlay. After applying a piece, check with a ruler and make supplements in time. Apply from the bottom of each grid, and pat and smooth it while applying. Pay special attention to the application of cement slag at the inner and outer corners, and pat it firmly to avoid black edges.

[0073] When the above decorative surface is in a semi-solidified state, brush it off with a brush dipped in water (or rinse it off with water from a sprayer) until the original stone is exposed.

[0074] After completing the above operations, after the partition strips are removed and the maintenance spraying is completed, wait until the moisture on the wall is dried, carefully remove the partition strips, and then use a line trowel to smooth and straighten the partition seams as required. Maintenance: After the decorative surface reaches a certain strength, it can be sprayed with water to prevent dehydration and shrinkage from causing hollowing and cracking.

[0075] From the above description, it can be known that the method for repairing water-brushed stone shield-shaped armorial decoration provided by the present invention constructs a template through the original shield-shaped armorial decoration, and repairs the original shield-shaped armorial decoration according to the template, with a high degree of restoration, and the mesh cloth can effectively prevent cracks from occurring on the water-brushed stone surface.

[0076] The above is only a specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any changes or substitutions that can be easily thought of by a person skilled in the art within the technical scope disclosed by the present invention should be included in the protection scope of the present invention. Therefore, the protection scope of the present invention shall be subject to the attached claims.
