Description

Technical Field

[0001] The invention belongs to the technical field of house inspection, and in particular relates to an intelligent evaluation method for residential structure quality based on house physical inspection. Background Art

[0002] With the rapid development of cities, the number of houses within an administrative area is increasing. However, while residential construction in China is developing rapidly, there are still some urgent problems to be solved: as time goes by, the number of old houses in towns is gradually increasing. Due to the low construction standards and lack of necessary maintenance of a large number of old houses, there are huge safety hazards. Cracks, leakages and other problems may occur, affecting residential safety. Combined with the house collapse incidents that have occurred across the country in recent years, the safety of houses involving the safety of life and property of the people has received more and more attention from the people and the government.

[0003] Urban residential physical inspection is a system for inspecting public parts of urban residential buildings that are built and put into use and other safety-related matters, and rectifying problems found in the inspection. However, current housing physical inspections usually only enter the results of the physical inspection into the system, and it is difficult to effectively supervise other aspects of the house through the system, such as the preliminary data of house construction, the detection and evaluation of the quality of residential structures in the medium term, and the monitoring and early warning in the later period, making it difficult to supervise the house throughout its life cycle. Therefore, a platform that can manage the house throughout its life cycle is needed to achieve the full life cycle management of the house and the detection and evaluation of the quality of the residential structure. The present invention solves this technical problem. Summary of the invention

[0004] In view of the defects in the prior art, the present invention provides an intelligent assessment method for residential structure quality based on house physical examination. By building a full life cycle management platform for urban housing and combining professional means, the detection and assessment of residential structure quality can be achieved, and the full life cycle management of the house can be carried out.

[0005] A residential structure quality intelligent assessment method based on house physical inspection comprises the following steps:

[0006] S1. The four levels of departments, streets, communities and property management work together to assist third-party agencies to enter the residential area, fully understand the specific situation of the residential area's quality and safety, collect basic information required for physical examinations, review original files, find out the design, construction, raw materials, service life, number of houses and other related basic information of the house, and realize the information survey of the house;

[0007] S2. Classify the houses according to their structural form, construction year, completeness of drawings, presence of elevators, heating methods, etc., and determine different house inspection indicators for different classifications;

[0008] S3. Conduct on-site inspections;

[0009] S4. Conduct non-destructive quantitative testing for houses with more serious problems;

[0010] S5. Conduct a comprehensive property assessment of the house based on data verification, on-site investigation and test results;

[0012] S7. Carry out repair work on the house according to the specific problems of the house;

[0013] S8. Choose the appropriate insurance type to purchase;

[0014] S9. Based on the results of the physical examination of the house, the house will be subsequently inspected, maintained or monitored on a daily basis.

[0015] Furthermore, the step S3 includes the following steps:

[0016] S31. Organize relevant personnel and professional medical examination institutions;

[0017] S32. Sort out key problems to be investigated, focusing on: foundation deformation, surrounding environment, cracks in the upper main structure, component deformation, steel bar corrosion, excessive deflection and component unevenness, leakage, hollowing and falling of the exterior wall or decorative layer;

[0018] S33. During the on-site inspection, the intelligent technology of "manual identification + drone oblique photography + thermal imaging camera" is applied to quickly identify problems in the house, so as to speed up the progress of house inspection and the accuracy of assessment.

[0019] Furthermore, the step S4 includes the following steps:

[0020] S41. Carry out non-destructive quantitative testing of houses in the following situations:

[0021] The house has exceeded its designed service life and needs to continue to be used;

[0022] The building foundation, walls or other load-bearing structures have potential safety hazards such as sinking, tilting, cracks, deformation, etc.;

[0023] The houses in a certain area are damaged by major natural disasters such as ground subsidence, earthquakes, typhoons, floods, etc., or by accidents such as fires and explosions, and need to continue to be used;

[0024] The building maintenance structure, building exterior decorations, external hangings and other ancillary facilities, building curtain walls or exterior wall insulation systems have abnormal deformation, falling off, bursting and other safety hazards that may endanger public safety;

[0025] S42. Physical examination personnel shall use instruments such as rebound testers and total stations to conduct non-destructive quantitative verification tests on material strength, cracks, deformation and other items of important parts that affect safety as a necessary means to determine dangerous points.

[0026] Furthermore, the step S5 includes the following steps:

[0027] S51. Based on the problems found in the data verification, on-site investigation and testing, identify and evaluate the potential hidden dangers in each part of the house that may affect the building safety, overall stability and bearing capacity of the house structure, draw physical examination conclusions and issue physical examination reports;

[0028] S52: If the physical examination results in passing, the building structure meets the requirements for safe use and can continue to be used normally;

[0029] S53. If the physical examination conclusion is basically passed, the house structure can basically meet the overall safety requirements, but some indicators are not up to standard and there are risk points. The physical examination institution should remind the house user to take timely measures such as repair or partial reinforcement according to the assessment results, and conduct regular inspections, maintenance and observation;

[0030] S54. If the physical examination concludes that the house has failed, the structure of the house cannot meet the requirements for safe use and there are serious safety risks. The house user should be required to entrust a professional organization to conduct a safety appraisal. If the house is appraised as a dangerous house, the appraisal organization should clearly put forward in the appraisal report the treatment opinions of observation of use, treatment of use, cessation of use or overall demolition according to the different degrees of danger, and issue a dangerous house management notice to the house user, put forward dangerous house management opinions, and urge the person responsible for the safety of the house to take measures to eliminate the danger in accordance with the requirements of the dangerous house management notice.

[0031] Furthermore, the step S6 includes the following steps:

[0032] S61. House archiving: Establish an effective data management center in the cloud, combine regional oblique photography data, and centrally manage multi-dimensional data such as basic building information, previous inspection reports, renovation design drawings, and daily maintenance data;

[0036] S65. Housing disposal and loss supervision: The physical examination conclusions, problem list disposal opinions, etc. are recorded in the platform by category. When old houses that are dangerous and have no repair value are found, they will be included in the scope of renovation by the local government. The whole process data of the loss disposal reasons, identification process, implementation plan, demolition process, etc. of the demolished buildings will be entered into the urban housing life cycle management platform;

[0037] S66. Enter the housing pension information and insurance information of the house into the urban housing life cycle management platform.

[0038] Furthermore, the step S8 includes the following steps:

[0039] S81. Introduce a competitive mechanism. Each insurance agency shall issue an insurance plan based on the actual situation of the houses in its jurisdiction. The sub-district shall select an insurance agency with a high comprehensive level to purchase insurance under the guidance of the housing and construction department.

[0040] S82. Use modern insurance functions to participate in the safety management of urban residences, and use the superposition of insurance types to drive the use of special residential maintenance funds to amplify the scale effect of funds; shorten the intermediate process of public part maintenance by advance payment of maintenance by insurance institutions; reduce the economic pressure of property owners by claiming part of the maintenance costs; reduce safety hazards and reduce the risk of claims through regular inspection services;

[0049] Figure 1 It is a flowchart of the present invention. DETAILED DESCRIPTION

[0050] The technical solution of the present invention will be clearly and completely described below in conjunction with specific embodiments and drawings.

[0051] See also Figure 1 , an intelligent evaluation method for residential structure quality based on house physical examination, comprising the following steps:

[0052] S1. The four levels of departments, streets, communities and property management work together to assist third-party agencies to enter the residential area, fully understand the specific situation of the residential area's quality and safety, collect basic information required for physical examinations, review original files, find out the design, construction, raw materials, service life, number of houses and other related basic information of the house, and realize the information survey of the house;

[0053] S2. Classify the houses according to their structural form, construction year, completeness of drawings, presence of elevators, heating methods, etc., and determine different house inspection indicators for different classifications;

[0054] S3. Conduct on-site inspections;

[0055] S4. Conduct non-destructive quantitative testing for houses with more serious problems;

[0056] S5. Conduct a comprehensive property assessment of the house based on data verification, on-site investigation and test results;

[0058] S7. Carry out repair work on the house according to the specific problems of the house;

[0059] S8. Choose the appropriate insurance type to purchase;

[0060] S9. Based on the results of the physical examination of the house, the house will be subsequently inspected, maintained or monitored on a daily basis.

[0061] The physical examination mainly includes four aspects: foundation, main structure, enclosure system, equipment and facilities, and pipelines. Physical examination indicators include three types of indicators: safety, durability, and applicability. The mandatory inspection items should cover safety indicators, and the optional items can be selected according to the characteristics of the house and work needs. The first physical examination should cover all indicators of the mandatory inspection items; subsequent physical examination indicators can be appropriately adjusted according to previous physical examination results.

[0062] The housing physical inspection process in this plan is divided into preliminary investigation and information collection, mid-term on-site inspection and non-destructive quantitative testing, and later physical inspection report. The overall work of the housing physical inspection is completed through multiple stages.

[0063] When conducting information surveys, you can also check geotechnical engineering survey reports, design drawings, completion acceptance materials, previous inspection reports, appraisal reports, renovation design drawings, and daily maintenance and use materials to make the survey content more comprehensive.

[0064] Furthermore, step S3 includes the following steps:

[0065] S31. Organize relevant personnel and professional medical examination institutions;

[0066] S32. Sort out key problems to be investigated, focusing on: foundation deformation, surrounding environment, cracks in the upper main structure, component deformation, steel bar corrosion, excessive deflection and component unevenness, leakage, hollowing and falling of the exterior wall or decorative layer;

[0067] S33. During the on-site inspection, the intelligent technology of "manual identification + drone oblique photography + thermal imaging camera" is applied to quickly identify problems in the house, so as to speed up the progress of house inspection and the accuracy of assessment.

[0068] Furthermore, the step S4 includes the following steps:

[0069] S41. Carry out non-destructive quantitative testing of houses in the following situations:

[0070] The house has exceeded its designed service life and needs to be continued in use;

[0071] The building foundation, walls or other load-bearing structures have potential safety hazards such as sinking, tilting, cracks, deformation, etc.;

[0072] The houses in a certain area are damaged by major natural disasters such as ground subsidence, earthquakes, typhoons, floods, etc., or by accidents such as fires and explosions, and need to continue to be used;

[0073] The building maintenance structure, building exterior decorations, external hangings and other ancillary facilities, building curtain walls or exterior wall insulation systems have abnormal deformation, falling off, bursting and other safety hazards that may endanger public safety;

[0074] S42. Physical examination personnel shall use instruments such as rebound testers and total stations to conduct non-destructive quantitative verification tests on material strength, cracks, deformation and other items of important parts that affect safety as a necessary means to determine dangerous points.

[0075] For the detection of houses, this program adopts the following methods:

[0076] Total station, which detects the verticality of houses, slope retaining walls and fences, has high-precision measurement capabilities and can accurately obtain relevant data;

[0077] The steel bar detection and locator is used to determine the material of the protruding parts. It can accurately detect whether the suspected parts are masonry components or concrete components, providing an accurate basis for subsequent processing;

[0078] Endoscope: After partially cutting the glue joint, the probe can be inserted into it to achieve a detailed inspection of the internal framework of the curtain wall structure and the installation quality, and potential problems can be discovered in time;

[0079] Infrared cameras and infrared camera drones can use infrared imaging technology to conduct a comprehensive inspection of the roof and accurately determine whether there is leakage;

[0080] Camera drones can conduct comprehensive inspections of the roof, clearly checking whether there is any illegal construction, providing strong support for roof management.

[0081] According to the actual situation, the staff may also choose other equipment to conduct the house inspection. The above content is only an example and does not limit the specific type of equipment.

[0082] Furthermore, the step S5 includes the following steps:

[0083] S51. Based on the problems found in the data verification, on-site investigation and testing, identify and evaluate the potential hidden dangers in each part of the house that may affect the building safety, overall stability and bearing capacity of the house structure, draw physical examination conclusions and issue physical examination reports;

[0084] S52: If the physical examination results in passing, the building structure meets the requirements for safe use and can continue to be used normally;

[0085] S53. If the physical examination conclusion is basically passed, the house structure can basically meet the overall safety requirements, but some indicators are not up to standard and there are risk points. The physical examination institution should remind the house user to take timely measures such as repair or partial reinforcement according to the assessment results, and conduct regular inspections, maintenance and observation;

[0086] S54. If the physical examination concludes that the house has failed, the structure of the house cannot meet the requirements for safe use and there are serious safety risks. The house user should be required to entrust a professional organization to conduct a safety appraisal. If the house is appraised as a dangerous house, the appraisal organization should clearly put forward in the appraisal report the treatment opinions of observation of use, treatment of use, cessation of use or overall demolition according to the different degrees of danger, and issue a dangerous house management notice to the house user, put forward dangerous house management opinions, and urge the person responsible for the safety of the house to take measures to eliminate the danger in accordance with the requirements of the dangerous house management notice.

[0087] The specific assessment includes the housing distribution physical examination result assessment and the housing comprehensive assessment, and the determination method is as follows:

[0088] Housing distribution physical examination results:

[0089] When the following situations exist at the same time, the evaluation result should be passed: 1. The design documents and construction acceptance materials are complete and reliable, or without professional design and construction, but no obvious safety hazards are found after safety appraisal; 2. The structure works normally, and no abnormal deformation or damage is found.

[0090] When one of the following situations exists, the evaluation result should be basically passed: 1. Abnormal deformation damage is found, but the limit and degree do not exceed the "failure index"; 2. There are no design documents and construction acceptance materials or there are doubts, and there is no safety appraisal report to prove its safety.

[0091] When one or more “failure indicators” appear, the assessment result is “failure”.

[0092] Comprehensive housing assessment

[0093] If individual indicators in the partial characteristic assessment do not meet the requirements, but there are no obvious safety hazards or illegal or irregular situations, it should be judged as passed.

[0094] There are risk points in the foundation or main structure, but there are no serious safety risks such as overall structural collapse, so it should be judged as basically passed.

[0095] If one of the assessment items of foundation or main structure characteristics fails to meet the requirements, there is a serious safety risk in the building structure and it cannot meet the requirements for safe use, and it should be judged as failed.

[0096] The disposal after the physical examination of the house should be based on the results of the above two assessments and be handled according to different situations. The specific methods are as follows:

[0097] If the physical examination conclusion is passed, continue to use it normally, and any indicators that do not meet the requirements should be repaired in a timely manner.

[0098] If the physical examination conclusion is basically passed, timely repair or local reinforcement and other remediation measures shall be taken according to the evaluation results, and regular inspection and maintenance shall be carried out to observe the use;

[0099] If the physical examination conclusion is not passed, the device should be stopped from use immediately, and emergency or reinforcement measures should be taken according to the evaluation results. It can only be used normally after the safety risks are eliminated. If a safety appraisal is required, a professional organization should be entrusted to conduct a detailed safety appraisal.

[0100] Furthermore, the step S6 includes the following steps:

[0101] S61. House archiving: Establish an effective data management center in the cloud, combine regional oblique photography data, and centrally manage multi-dimensional data such as basic building information, previous inspection reports, renovation design drawings, and daily maintenance data;

[0106] S66, inputting the housing pension information and insurance information of the house into the urban housing full life cycle management platform. The management platform includes the housing pension information, insurance information and physical examination information of the house, thereby realizing the full life cycle management of the house.

[0107] The urban residential life cycle management platform can realize the intelligent assessment of housing risks. The platform covers the entire process of basic housing information, inspection, care, maintenance, loss and demolition, and has the collection and classification of preliminary data of regional buildings and one file for each floor of the platform; during the mid-term inspection, housing safety risk identification, analysis, assessment, and grading and classification are carried out, and in the later stage, it has a series of functions such as monitoring and early warning, general management, and hazard resolution. It also realizes data sharing with property management platforms, housing insurance information platforms, etc., and digitally empowers closed-loop management of housing safety. Staff can upload corresponding data to the platform, so that the platform can achieve the above-mentioned functions.

[0108] For dangerous houses, staff can use sensors to collect data on dangerous houses, and the collected data will be uploaded to the management platform to monitor the dangerous houses. When the situation in the dangerous houses is abnormal, the platform will issue an early warning, so that the situation of the dangerous houses can be known in time and the management of the dangerous houses can be achieved. After the crisis is resolved, the early warning can be cancelled and the crisis can be resolved.

[0109] Furthermore, the step S8 includes the following steps:
