抗震型屋面变形缝怎么算
配装及及特性：抗震型楼地面变形缝的材料配置不同于墙面和屋面伸缩缝。不仅要考利到建筑伸缩位移，还要考利到防防水、抗震、防滑、抗压等应素。因此。地面伸缩缝的材料选择比墙面要求高。可选择纯铝板。镀锌钢板。或者黄铜板。这这三种板选择是根据室内装修的沉重力的要求变化而变化。起承重力**高的为镀锌帮。楼地面变形缝的材质特想如下：
纯铝板楼地面伸缩缝盖板：
镀锌钢板楼地面伸缩缝盖板特性：
黄铜楼地面伸缩缝盖板特性：
普通黄铜是铜锌二元合金，其含锌量变化范围较大，因此其室温组织也有很大不同。根据Cu－Zn二元状态图（图6），黄铜的室温组织有三种：含锌量在35%以下的黄铜，室温下的显微组织由单相的α固溶体组成，称为α黄铜；含锌量在36%～46%范围内的黄铜，室温下的显微组织由（α+β）两相组成，称为（α+β）黄铜（两相黄铜）；含锌量超过46%～50%的黄铜，室温下的显微组织仅由β相组成，称为β黄铜。
Beautiful floors, telescopic material of fittings and to recognize and characteristics: building material of ground of expansion joint configuration is different from the walls and roof expansion joints. Should not only cowley to building expansion displacement but also cowley to prevent waterproof, seismic, non-slip, such as compressive strength should be plain. So. Ground of expansion joint selection of materials is higher than metope requirements. Can choose pure aluminum plate. Galvanized steel. Or brass sheet. Choice is that these three plate according to the requirements of the indoor decoration of heavy force. Since the highest for galvanized help bearing capacity. Building the ground deformation cracks of material according to below:
Pure aluminum plate floors, expansion joint cover:
Al: aluminum silicon Si 99.60:0.25
Copper Cu: 0.05
Magnesium Mg: 0.03
Zinc and zinc: 0.05
Manganese Mn: 0.03
Ti Ti: 0.03
Vanadium V: 0.05
Iron Fe: 0.350
Note: a single: 0.03
1060 aluminum plate density of 0.00000268.
Tensile strength of sigma b (MPa) : 110-136
Elongation delta (%) : 3-5
Galvanized steel floors, expansion joint cover features:
(1) low hardenability. In general, carbon steel water quenching of the biggest hardening only 10 mm to 20 mm in diameter.
(2) the strength and QuJiang is lower. Such as ordinary carbon steel Q235 steel for sigma s 235 mpa, while low alloy structural steel, 16 mn sigma s for more than 360 mpa. 40 steel sigma s/sigma b 0.43, far below the alloy steel.
(3) the tempering poor stability. Due to tempering poor stability, carbon steel during tempering treatment, in order to guarantee high strength to use low temperature tempering, so the toughness of the steel is low; In order to guarantee good toughness, high intensity and low when the tempering temperature, so the comprehensive mechanical properties of the carbon steel level is not high.
(4) can't meet the requirements of special performance. Carbon steel in antioxidant, corrosion resistant, heat resistant, good low temperature resistance, wear resistance and special electric magnetic often is bad, can't meet the needs of special performance.
Brass floors, expansion joint cover features:
Ordinary brass is binary copper zinc alloy, and its zinc content range is bigger, so there are quite different in its organization at room temperature. According to Cu - zinc binary state diagram (figure 6), there are three kinds of brass room temperature organization: zinc content under 35% of brass, the microstructure at room temperature is composed of single phase alpha solid solution, known as alpha brass; Zinc content in brass within the scope of 36% ~ 46%, the microstructure at room temperature by two phase composition (alpha + beta), referred to as a (alpha + beta) brass (duplex brass); Zinc content more than 46% ~ 50% of brass, the microstructure consists only of beta phase at room temperature, known as beta brass.
