[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a method for repairing a deteriorated wall surface of a building, and a method capable of quickly and accurately predicting current and future costs using images.
[0002]
[Prior art and its problems]
Concrete, mortar, sizing, etc. are often used as the material for the walls of buildings such as detached houses and condominiums. It is inevitable that these materials themselves and the coating film coated on the surface of the materials are subject to deterioration over time such as cracking, peeling, and partial destruction due to floating settlement of the building, ultraviolet rays, rainwater, or the like.
[0003]
Until now, no means has been established for quantitatively and accurately grasping or predicting the deterioration degree of these materials and coating films and their repair methods, and relying on the experience and can of each supplier. Is most. However, since these repair methods and costs are grasped and predicted by individual techniques, there is a large variation and it is extremely difficult to grasp or predict accurately.
[0004]
The repair method and cost can be accurately grasped according to the degree of deterioration of the wall material, and if it can be done with images, even an amateur can easily understand and convince, so repair The trust relationship between the contractor and the client (client) is improved, and the effect that the client's anxiety can be resolved can be expected.
[0005]

That is, according to the present invention, the deterioration phenomenon with time is classified for each material of the building wall (step 1), and the deterioration phenomenon is performed by combining each material and environmental factors for each deterioration phenomenon classified for each material. Rank the grades of degradation in the range from the one that has not occurred at all to the one in which it has occurred significantly evenly into a plurality of grades, grade it in 3 to 10 levels, and the causes and progress of these degradations In addition, the repair mechanism and cost required for each rank are set in advance (step 3), and the wall of the building to be repaired is the Confirming whether it corresponds to the rank, and recognizing the repair method and cost corresponding to the rank set in advance in step 3 based on that (step 4), and of these steps 1 to 4 Building wall material way repair, characterized by performing part or all the images (hereinafter, referred to as "the method 1") is provided.
[0007]
Further, the present invention predicts the future deterioration of the target building wall surface in consideration of the type of material, the location of the wall surface and the location environment of the building (step 5), and the result is classified for each material. For each deterioration phenomenon, each material and an environmental factor are combined, and the degree of deterioration in a range from the case where the deterioration phenomenon does not occur to the case where the deterioration phenomenon occurs remarkably is ranked into a plurality of evenly. Grades are assigned to ranks that are supplemented with the causes of these deteriorations and the mechanism of their progress, and are applied to the repair methods and costs required for each rank. In addition, a future wall surface repair method and cost prediction by image (step 6) are also included, and a wall surface material repair prediction method (hereinafter referred to as “the present method 2”) is also included.
[0008]
Hereinafter, the present invention will be described more specifically.
[0009]
DETAILED DESCRIPTION OF THE INVENTION
Method 1: Classify the deterioration with time for each material of the building wall (Step 1), rank the degree of deterioration for each deterioration phenomenon classified for each material (Step 2), and repair each rank. The method and the cost required for it are set in advance (step 3), and then the rank of the wall of the building to be repaired is checked in which rank in step 2 and is set in advance in step 3 based on it. It is a method for repairing a building wall material characterized by recognizing a repair method and cost corresponding to the rank (step 4), and performing some or all of these steps 1 to 4 by an image. .
[0010]
The building in Method 1 is not particularly limited. For example, a detached house, an apartment house, an apartment, an office, a school, a welfare facility, a hotel, an inn, a medical facility, a factory building, a warehouse, a playground, a gas station, a bridge , Pedestrian bridges, vehicles, fences, tunnels, power plants, road facilities, ships, towers. These wall surfaces include the inner and outer walls of the building, as well as roofs, eaves, handrails, stairs, parapets, nose tips, and the like. Examples of the wall material include mortar, sizing, concrete, tile, plaster, panel and paint film.
[0011]
Step 1 is to classify the deterioration with time for each material of the building wall surface. Classification can be performed based on data and information such as past experience and achievements.
[0012]
The deterioration of the material with time is often caused and progressed by, for example, floating settlement of a building or exposure of a wall surface to ultraviolet rays or wind and rain. Types of deterioration phenomenon include, for example, discoloration, cracking, swelling, peeling, dirt (rain stains), choking, rust, corrosion, cracking, cracking, defects, destruction, color unevenness, breaking, warping, plants (moss, mold, Such as algae).
[0013]
In step 1, it is necessary to combine the building, the wall surface, the type of the material, and the like, and classify each of them according to the deterioration phenomenon. For example, deterioration over time that occurs on the concrete outer wall surface of a condominium includes cracking, peeling, cracking, breaking, breaking, warping, and the propagation of plants (moss, mold, algae, etc.).
[0014]
Step 2 is to rank the degree of deterioration for each deterioration phenomenon classified for each material performed in step 1.
[0015]
The range from the one where no deterioration phenomenon such as cracking, peeling, cracking, or defect has occurred to the one that has occurred remarkably is ranked in a plurality almost evenly, and graded in stages (for example, 3 About 10 to 10 steps). Each rank is preferably clearly defined so that it can be distinguished from other ranks.
[0016]
Since the amount of deterioration and the speed of the wall surface deterioration are affected by the environment in which the building is installed even if they are the same material, it is preferable to add an environmental factor. Environments include, for example, quiet residential areas, densely populated areas, factory areas, beach areas, forest areas, exhaust gas-rich areas, wetland areas, dry areas, vibration-prone areas, downtown areas, cold areas, warm areas, tropical areas The area, age of the building, etc. can be raised. It is more preferable to rank the degree of deterioration phenomenon in each case step by step by combining each material of the wall surface and environmental factors.
[0017]
Further, it is preferable to supplementarily explain the cause of the deterioration and the mechanism of progression.
[0018]
For example, there are “stains due to foreign matter” represented by dust and dust and “stains caused by plants” represented by moss, algae, and mold, etc., particularly carbon dioxide contained in automobile exhaust gas etc. “Stain due to foreign substances” due to lipophilic substances is the main cause of rain streak stains. The dirt generation mechanism is such that dust or dust that falls due to gravity from the top of the building accumulates on the wall or the coffin, and that dust or dust adheres to the wall due to static charge on the building wall. Can be considered. Furthermore, it may be caused by leaving pollutant traces on the wall surface after the water evaporates after falling into polluted water due to rain or the like, evaporating the water.
[0019]
Cracks in the wall of a building can be broadly divided into cracks in the “concrete frame” and “finished layer itself”. This generation mechanism includes behaviors due to external forces such as earthquakes (deformation, shaking, distortion, etc. of buildings), wall behaviors due to temperature fluctuations (finishing materials and expansion and contraction of housing due to solar radiation), behaviors due to changes in humidity (water absorption) For example, finishing material and expansion / contraction of the housing), behavior due to poor construction (housing of the housing / contamination of foreign matter, material selection error, etc.).
[0020]
Step 3 is to set a repair method and cost required for each rank in advance.
[0021]
The contents of the wall repair work differ depending on the degree of deterioration, and in the case of mild deterioration, the work contents are simple and low cost, but as the deterioration progresses significantly, the contents of the repair work become complex and sophisticated, Naturally, the cost is inevitably increased.
[0022]
The wall surface can be repaired by a method known per se. A repairing method for cracks, cracks and defects that occur relatively frequently as a deterioration phenomenon will be described.
[0023]
Cracking is a phenomenon that often occurs in concrete and mortar materials. First, check the width of the crack. If the crack width is 0.5 mm or less, a polymer cement or a slightly elastic protective adjusting material is poured or applied to the cracked part using a duster brush or the like. If it exceeds 0.5mm, (1) after U cut, after sealing treatment, after acrylic urethane sealing or polyurethane sealing, treat with polymer cement or fine elastic protection adjusting material, (2) drill the part with a drill Open and inject high pressure epoxy resin, then repair with polymer cement, (3) Inject low pressure epoxy resin with temporary seal, cylinder injector, etc., then repair with polymer cement .
[0024]
Uki is a phenomenon in which a part of the mortar part peels from the substrate. In the case where the ground portion is peeled off by impact, it can be repaired by removing the weakened mortar around the peeled portion and molding the polymer cement mortar.
[0025]
In addition, there is an anchor pinning method for fixing the mortar portion where the climax has occurred. This is performed by inserting a stainless steel pin into this portion to fix the portion, and repairing the hole portion with an epoxy resin or the like so as to be inconspicuous.
[0026]
The defect is a phenomenon in which a part of the wall surface is missing. The missing part can be repaired by removing the weakened concrete and then polymer-molding the mortar. In addition, in some cases, the reinforcing bars may be exposed at the part where the hanger has been removed. In this case, after removing the floating rust, apply rust neutralization inhibitor to the concrete ground around the reinforcing bars. It is preferable to repair by exposing the reinforcing bar exposed part and its peripheral part to polymer cement-based mortar after kneading the polymer cement.
[0027]
The repair cost varies depending on the degree of deterioration and the content of the repair work, but is the cost including all the material costs, labor costs, miscellaneous expenses, etc. from the start to the end of the repair work at each degree of deterioration. It is necessary to calculate and set costs for various cases in advance.
[0028]
In step 4, the wall surface of the building to be repaired is classified according to the material in step 2 and the rank of the degree of deterioration is classified for each deterioration phenomenon. This is a step of recognizing the repair method and cost corresponding to the set rank.
[0029]
Information such as the material content of each part of the wall surface of the target building to be repaired, the location environment, and the degree of progress of the deterioration phenomenon at present is accurately and objectively grasped by visual and other methods. Based on this, the rank of the degree of deterioration in step 2 is confirmed. Then, by applying the confirmed rank to the rank set in advance in step 3, the repair method and the cost of the wall surface of the target building can be grasped.
[0030]
A feature of the present method 1 is that some or all of these steps 1 to 4 are performed using images.
[0031]
Here, the “image” does not include “representing only with characters”, and includes, for example, photographs (monochrome or color), illustrations, drawings, animation (animation), movie shooting, video shooting, and the like.
[0032]
Specifically, in step 1, the deterioration with time of the wall surface of each material is classified based on the image. Further, in step 2, ranking of the degree of deterioration is performed on the basis of images for each deterioration phenomenon for each material. In step 3, the repair method for each rank is performed using an image, and the cost required for the rank can also be expressed using an image if necessary. Next, the degree of deterioration of the wall surface of the building to be repaired is also expressed by an image, and it is confirmed in which rank of the image performed in step 2 it is set in advance in step 3. The method 1 is achieved by recognizing the repair method and cost corresponding to that rank. Further, it is preferable that the deterioration mechanism can be expressed by an image.
[0033]
This method 2: Predicting the future deterioration of the target building wall surface (Step 5), applying the result to the above Step 2 and Step 3, and predicting the future wall surface repair method and cost by image ( This is a method for repairing a building wall material characterized by step 6).
[0034]
Step 5 is to predict the progress of deterioration of the wall surface of the target building in the future.
[0035]
For example, in a region where the material of the wall is mortar, the location environment of the building is warm, and there is a lot of exhaust gas, the above-mentioned deterioration phenomenon has not progressed at all from “Stage 1” to “Stage 10”. Assuming that the above is assumed, in Step 5, it is predicted in advance in conjunction with the elapsed period how far the target building wall surface will deteriorate in the future. Specifically, even if it is currently “Stage 1” (no degradation phenomenon has occurred), it is predicted how much deterioration has occurred in 1 year, 2 years, 5 years, and 10 years. Further, it is to predict individually until reaching “stage 10” (the deterioration phenomenon is remarkably progressing).
[0036]
In step 5, it is preferable to perform the deterioration prediction in consideration of not only the type of material but also the part of the wall surface and the location environment of the building. Select as many factors as possible, such as materials and location environment, combine them with one or more, assume various situations, classify the deterioration over time in each of them, and for each classification, It is preferable to accumulate as much information as possible by precisely predicting the degree of progress of deterioration. It is suitable that these are expressed by images as much as possible.
[0037]
Step 6 is to apply the result of Step 5 to Step 2 and Step 3 above, and to perform a future wall surface repair method and cost prediction using images.
[0038]
Specifically, the progress of the future deterioration of the actual building wall is predicted according to step 5, and the result is ranked according to the degree of deterioration for each classified material and deterioration phenomenon performed in step 2. The repair method and the cost required for the repair method and the cost required for the repair method set in advance in the rank in step 3 are the repair method and the cost required for the future.
[0039]
As a result, it became possible to quickly predict the degree of wall material deterioration after one, two or five years from the target building. And it is possible to easily grasp the repair method and the cost required for it in the future.
[0040]
By preparing each work in these processes so that they can be performed with images, the owner (owner) of the target building can easily understand the repair of the wall surface, and the explanation by the repairer can be understood. It becomes easy.
