? Basic standards (a) Independent column base with a single base unit of a column; (b) the length of the strip foundation with a natural inter-sided units; (c) to the area of ??a natural-out basis between units 1 wall at high level, a natural side between units; 2, column high level, one of the unit; 3, beams, joists, purlins, etc. In a span of one to four units, panels to blocks, ramming plate to a natural area between units; 5, roof trusses with a Pin ground units, based on the standard one, if the foundation should slip, or insufficient carrying capacity there are other causes of uneven settlement of causing obvious structural distortion, displacement, crack, tilt, etc. but also the deterioration of two, to increase the gene adjacent to the building load, or due to their own local increase in floor loading, and other man-made factors have led the settlement, causing significant housing structure distortion, displacement, crack, tilt, etc. but also the deterioration of three, from basic aging, corrosion, broken and so the situation caused by the housing structure has obvious distortion, displacement, crack, tilt, etc. but also worsening standard wall studs 1, Qiang Zhu cracks or reinforced protective layer off the main leak, or have a significant amount of horizontal fractures, crush, etc. 2, the middle part of the wall to produce significant cross crack, or peel off the protective layer with 3 columns, walls produce tilt, tilt it more than the height of 1/100 4, columns, walls cracked concrete crisp carbonation, from the dark, undermining the whole surface area of ??more than 1/3, and the reinforcement exposed, severe corrosion, reducing the beam cross-section standard one, single or the middle part of the beam to produce a continuous beam boast transverse rupture, or a high beam is extended upward to reach more than 3/2, falling below the protective layer 2 with vertical cracks, Charpy, continuous beam ends noticeable diagonal crack, cantilever beams with significant vertical or diagonal crack crack 3 frame beam at the fixed end produce significant vertical or diagonal crack crack, crack or cross-4, panels produce significant vertical cracks below 5, ramming above board surrounding cracks, or cross-cracks 6 below, a variety of beams, plates generate more than 1/150 of the span deflection, and by the crack width is greater than the tensile zone 1mm 7, all kinds of board protection layer peeling, more than half of the exposed reinforcement, severe corrosion cross-section reduction of 8, prestressed precast panels produced through vertical cracks; or ends exposed tendons loose concrete, reinforcement of its length of more than 100 standard one roof trusses, generate more than 1/150 of the span deflection, and the lower chord cracks than 1mm Vertical cracks 2, support system failure led to tilt, tilted roof truss height exceeds 2/100 3, peeling off the protective layer, many exposed reinforcement, corrosion 4, end node loose connections, and there is obviously a standard wall cracks, wall produce joints longer than 1/2 storey, slit width is greater than 2cm vertical cracks, or to produce joints longer than 1/3 of the multi-storey vertical cracks in two pieces, wall beam support under significant vertical 3 crack wall between window and door openings or windows to generate significant cross cracks or vertical or horizontal crack crack 4, tilted, the tilt of more than 1.5 storey / 100 (three or more, more than the total height of 0.7 / 100) or adjacent wall joints broken into slits 5, weathered, peeling, chalking mortar, leading up to the wall and effectively weaken more than a quarter-section (an average of more than one third) column Standard 1, pillar production level crack, or produce through vertical cracks 1/2, beam support column below its high seam longer than the column generated more than three vertical cracks, tilted, the tilt of more than 1.2 storey / 100 ( three or more, more than the total height of 0.5 / 100) 4, weathering, cut off, mortar chalking, leading to effective cross weaken over 1/5 or more (up to 1/4 of the cottage above) lintels, arches standard one, over the central beam produce significant vertical cracks; or ends noticeable diagonal crack; or support beams generated over the wall horizontal fracture; or produce significant bending, sinking deformation 2, barrel arch, flat shell, wave barrel arch, vault Bus cracks; or arched significant deformation; or arch apparent displacement; or arch lever loose, or severe corrosion, reducing cross-section summary: The above is part of the dilapidated cement house appraisal standards, as the dilapidated mud house appraisal standards if we have needs, then you can leave a message below the small series will give everyone says about the dangerous accreditation standards Xiao Bian gave you so much, we must pay attention to the identification of dangerous oh above provided by Chengdu interior finishing original Taken: http: // www. chengdushinei.com/engineerdeta-18375.html
