Light weight panels for partition walls used in buildings1 ScopeThis Standard specifies the terms, classification, requirements, test methods, inspection rules, marks, transport and storage of light weight panels for partition walls used in buildings (hereinafter referred to as “light weight panels”). This Standard is applicable to light weight panels for non-load bearing partition walls used in general buildings.2 Normative referencesThe following standards contain the provisions which, through reference in this Standard, constitute the provisions of this Standard. The parties who enter into agreement based on this Standard are encouraged to use the latest versions apply to this Standard. GB 2828 Sampling procedures for inspection by attributes GB 6566 Limits of radionuclides in building materials GB/T 9978 Fire-resistance tests - Elements of building construction GB/T 13475 Thermal insulation - Determination of steady-state thermal transmission Properties - Calibrated and guard hot box GB/T 17431.1 Lightweight aggregates and its test methods - Part 1. Lightweight aggregates GBJ 75 Acoustics-measurement of sound insulation in buildings- specifications3 Terms and definitionsThe following terms and definitions apply to this Standard. 3.1 lightweight panel Prefabricated panel made by lightweight materials or in lightweight construction, and used for non-load bearing partition walls, of which areal density is not greater than the value stipulated in this Standard, and length-width ratio is not less than 2.5. 3.2 hollow cores panel Prefabricated panel of which a number of through-holes along the longitudinal direction of plates. 3.3 solid panel Prefabricated panel, without holes, that is made by materials of same kind. 3.4 composite sandwich panel Prefabricated panel composed by two and more materials of different functions, or composed by panel (casting surface layer) and core layer material. 3.5 out heed and inter orifice General term for mortise, rabbet and joint groove set on both sides of panel.4 Classification4.1 Classification and code According to sectional configuration, lightweight panel is divided into hollow cores panel, solid panel and composite sandwich panel; OR ordinary panel, door frame panel and irregular panel, according to component type of panel. The classification and code of lightweight panel are shown in Table 1. Table 1 Classification and code of lightweight panel Classification method Name Code According to sectional configuration Hollow cores panel Solid panel Composite sandwich panel According to component type of panel Ordinary panel Door frame panel Irregular panel PB MCB YB 4.2 Product type The lightweight panel can be made as hollow cores, sandwich and composite sandwich type. It shall use different out heed and inter orifice, and opening but it shall all comply with the provisions of Article 3.1 and Clause 5 of this Standard. mm × 30 mm 6 Wall thickness b / mm ≥ 12 NOTE Defects in 3, 4, and 5 that are lower than the limits are negligible while defects that are higher than the limits are unqualified. a This inspection is for composite sandwich panel. b Wall thickness shall be inspected for hollow cores panel. 5.3 Size deviation Panel size tolerance shall comply with the provisions in Table 3. Table 3 Size tolerance unit. mm No. Item Size tolerance 1 Length ± 5 2 Width ± 2 3 Thickness ± 1 4 Panel surface levelling ≤ 2 5 Diagonal difference ≤ 6 6 Lateral bending L / 1000 5.4 Physical and mechanical properties Corresponding use area, physical and mechanical properties indexes stipulated by different moisture content of panel shall comply with the provisions in Table 4 and Table 5. Table 4 Corresponding use area stipulated by different moisture content of panel Moisture content % ≤ 12 ≤ 10 ≤ 8 Use area Moist Medium Dry NOTE Moist area refers to the area where annual average relative humidity is greater than 75%; Medium area refers to the area where annual average relative humidity is 50% ~ 70%; Dry area refers to the area where annual average relative humidity is less than 50%. be equal to panel width. 6.4.2.5 Place it for 2 min after the first four grades are applied. When the fifth grade of load is applied to 1.5 times panel weight, place it for 5 min. If it continues to applying load, circulate this grade loading mode till it breaks and cracks. 6.4.2.6 Record the total load from the first grade of load to the fifth grade (or the grade before it breaks and cracks) as test results. 6.4.2.7 The test results only apply to panels of which the length is within the size scope of panels for test. 6.4.3 Compressive strength test 6.4.3.1 Along with the direction of panel width, Successively cut out unit test specimen of which the thickness equals to panel thickness, height is 100 mm and length is 100 mm (for hollow cores panel, the length shall include a whole hole’s length and the unit test sample’s of two complete holes ribs). Three unit specimens form a group. 6.4.3.2 Process the upper surface and the lower surface of specimen, so as to make it a plane that is parallel to each other and vertical to specimen hole cylinder axis. Modulate the cement mortar to process the upper surface and the lower surface. And use horizontal rule to adjust it level. 6.4.3.3 Place specimen on testing machine’s bearing plate, so as to make specimen axis coincide with pressure center of bearing plate. Apply load at 0.05~0.10 MPa/s till specimen breaks. Record the maximum failure load P. 6.4.3.4 Compressive strength of each specimen shall be calculated according to formula (1), and make it accurate to 0.1 MPa. Where, R - Compressive strength of specimen, in megapascal (MPa); P - Failure load, in newton (N); l - Length of specimen’s receiving surface, in millimeter (mm); b - Width of specimen’s receiving surface, in millimeter (mm). Panel’s compressive strength shall be represented by the arithmetic mean of compressive strength of three panels, and make it accurate to 0.1 MPa. 6.4.4 Softening coefficient test 6.4.4.1 Take a piece of test panel. Extract specimen along with panel length direction, i.e., a specimen of which the height is 100 mm, and length is 100 mm, six specimens in total in two groups, th... ......Source: Above contents are excerpted from the full-copy PDF -- translated/reviewed by: www.ChineseStandard.net / Wayne Zheng et al. |
