 Shenzhen housing construction Housing construction company _ what to do to detect - a reference construction, housing quality comprehensive testing 1. Definition and scope of housing quality comprehensive testing comprehensive testing of housing quality is through housing construction, construction materials, decoration materials, equipment, etc. comprehensive testing, to establish and improve the quality of housing archives, housing quality evaluation process, comprehensive quality testing houses mainly applied to protect the construction of houses in need of a comprehensive inspection. 2, housing a comprehensive quality inspection should include the following basic elements: 1) survey of housing construction, use and repair of history, architectural style, architecture and other information. 2) the establishment of general layout, floor plan, elevation, section, structural plan, the main component screenshots drawings, charts and graphics data files. 3), sampling and testing load-bearing structure of the material properties of housing, member number and location of sampling should comply with the relevant standards. Sampling sites should contain corrupted member representative. 4), and other testing house construction, renovation and equipment of soundness, analyze causes of damage. 5) detecting houses tilt and uneven settlement status quo. 6), according to the mechanical properties of structural materials found houses, according to the current load, use and housing structure system, establish a rational model, checking houses now carrying capacity. 7), according to the mechanical properties of structural materials found houses, according to the existing service load conditions and housing structure system to Shanghai seismic response spectrum, establish a rational model, checking the seismic capacity of buildings now, and review the seismic structural measures. 8) health checks housing of the device. Comprehensive testing should be increased to protect the building site of the fitness status of protection focuses on the detection. Second, the housing damage trend detection 1. Definition and scope of housing damage trend detection houses damaged trend detection by acting on the factors engineering and other adjacent buildings by external factors or design, construction, use and other housing inner generate or may monitoring processes cause damage deformation, displacement, cracks, housing damage trend detection for a variety of factors that may have caused damage or the need for monitoring of houses. 2, houses damaged trend detection should include the following elements: 2.1 Initial testing: 1) The text, drawings, photos or video and other methods to damage parts of the recording member housing construction, decoration and equipment, scope and extent, and make a mark. 2) to reflect the characteristics of the site set up housing displacement vertical displacement, horizontal displacement and tilt monitoring points. Monitoring position, density should be set according to the actual situation, every house monitoring points should be less than four. 3) Measure the vertical displacement, horizontal displacement, tilt Initial monitoring points should be repeated three times measured, the average value as the initial value of the monitor. 4) According to the structural characteristics and influencing factors of housing, development of monitoring programs; the development of monitoring timing, duration, frequency, and measuring the results of submission, and in the monitoring process, according to the changes, make appropriate adjustments. 2.2 damaged trend monitoring 1) Each monitor should be the same monitoring methods, monitoring personnel should be relatively fixed, and should be synchronized record corresponds to affect changes in factors. 2) Each monitor should be using the same equipment, before the monitoring, calibration should be checked. Level measurement accuracy not less than ± 0.1mm, theodolite accuracy not less than ± 6 ". 3) vertical displacement monitoring, should be laid into a closed loop or other forms annexed leveling line. Reference point must be set to vertical displacement of the outside the region, and not less than two. 4) horizontal displacement monitoring network, can be used triangulation, wire mesh and other forms. 5) tilt monitoring can be vertical quasi theodolite construction survey on the overall stiffness of the better houses tilt monitoring , can be the basis of differential settlement project housing tilt value. 6) regular observations recording houses damage phenomenon and developments. 7) timely analysis of monitoring data, draw curves, analyze the rate of change and the change the cumulative value, unusual, timely notice Principal 2.3 retest 1) retest should be stable after the impact. 2) using text, drawings, photos or video and other methods to damage parts of the recording member housing construction, renovation and equipment, scope and extent of initial recording control, monitoring changes in the process of determining the fitness condition of housing. 3) Calculate the housing vertical displacement, horizontal displacement, cumulative total inclined. 4) analyze the reasons damaged houses, according to "Housing DAMAGED grading standards" (Trial version) and "dangerous building identification standard" CJ13 assessed the extent of housing damage and propose appropriate measures to deal with. Third, the aseismic ability to detect 1. Definition and scope of the aseismic ability to detect seismic capacity of buildings detected by detecting the status quo of quality housing process, according to seismic requirements set for buildings in earthquake intensity specified safety assessment. ASEISMIC ability to detect not apply to seismic fortification level or lower than the current provisions of the houses, especially the protection of buildings, urban Lifeline works and alterations in floor houses 2, house seismic capacity testing should include the following elements 1), collect houses geological survey report, as-built drawings and project acceptance documents raw data, if necessary, supplement engineering geological investigation. 2) comprehensive inspection and record housing foundation, damaged parts of the load-bearing structure and envelope structure, scope and extent. 3), the survey analyzes the characteristics of the housing structure, structural arrangement, structural measures, such as seismic, seismic capacity review. 4), the general housing should Press "Seismic identification standard" GB50023-95, using the appropriate identification methods step by step, a comprehensive analysis of seismic capacity. 5), the overall seismic capacity of existing buildings to make assessment, does not meet the seismic requirements of houses, according to the relevant technical Standard propose the necessary measures for seismic reinforcement and seismic mitigation countermeasures. 6), to carry out alterations in floor houses should be "Seismic design procedures" DBJ08 ability to detect seismic Fourth, houses the fitness condition detection 1, houses the fitness status Definition and Scope houses the fitness condition detecting detected by examining housing construction, renovation and equipment of the fitness status, determine the course perfect grade of buildings. Housing is suitable for detecting the fitness condition assessment of housing, housing management, etc. need to determine the fitness The extent of the housing 2, houses the fitness status tests include the following elements: 1) to investigate the use of housing history and architecture. 2) measurement of tilt and uneven settlement house situation. 3), using text, drawings, photos or video and other methods, the recording house building components, damaged parts decoration and equipment, scope and extent. 4), analyzed the reasons damaged housing. 5), a comprehensive assessment of perfect grade of buildings. After checking the condition of damaged houses should be "perfect grade of buildings and Evaluation Standards" (Tentative) execution, and should follow the "dangerous building identification standard" CJ13, "the reliability of the identification standard industrial plant" GBJ144-90 and other relevant standards. When detected dangerous signs of houses, you must notify the principal in a timely manner house safety testing. When detected Housing dangerous point for risk must promptly by the principal.
