如何挑选合适的彩色压型钢板?

来源:/ 日期:2019-12-06 发布人:admin
  1)根据建筑立面要求选择板材类型:实际工程的建筑图纸只给出了金属屋面和墙面的范围和墙板的铺设方法(水平铺还是垂直铺),很少指定板材类型。因此,有必要根据建筑立面的要求选择合适的板材类型。例如:墙板需要垂直放置,可以选择yx15-225-900和yx25-210-840;对于平房立面效果的项目,建议采用yx25-200-1000,使立面更加美观,便于施工。如需卧铺,可使用波形yx18-76-836和yx18-63.5-825,还可使用兽皮型yx38-310或yx58-310、yx50-373。
  1) select the type of slab according to the requirements of building facade: the architectural drawing of the actual project only gives the scope of metal roof and wall surface and the laying method of wallboard (horizontal or vertical laying), and rarely specifies the type of slab. Therefore, it is necessary to select the appropriate type of slab according to the requirements of the building facade. For example: the wallboard needs to be placed vertically, and you can choose yx15-225-900 and yx25-210-840; for the project with bungalow facade effect, it is recommended to use yx25-200-1000 to make the facade more beautiful and convenient for construction. If you need a sleeper, you can use waveforms yx18-76-836 and yx18-63.5-825, and you can also use animal skin yx38-310 or yx58-310, yx50-373.
  2)根据保温棉的厚度选择板材类型:同一栋建筑应位于不同的位置,不同的用途,对保温有不同的要求。确定保温棉厚度后应根据保温棉厚度选择板。当保温棉的壁厚在100mm及以上时,要选择帮助较高的墙板相对较高,例如:yx28-820和yx25-210-840比较会选择前者,且最好是反向轧制。当墙壁保温棉厚度大于50mm时,不宜选择帮助高低小的波纹板,否则墙面轻易扩散不平整的情况,影响建筑物的美观。当保温棉厚度大于100mm时,可以选择yx75-760,当保温棉厚度大于150mm时,尽量选择双层屋面。如果选择yx75 - 760作为屋面板(注意这是一种无知和滑动支座连接钉板类型),即使没有绝缘要求,还希望添加50毫米厚保温棉,因为没有保温棉将导致屋面板、桁条噪声影响,加上保温棉,保温棉生产阻力支撑屋面板,yx75 - 760链接不会产生疲劳损伤。
  2) select the type of board according to the thickness of insulation cotton: the same building should be located in different locations, different uses and different requirements for insulation. After determining the thickness of the insulating cotton, the Board shall be selected according to the thickness of the insulating cotton. When the wall thickness of insulation cotton is 100mm or more, the wall panel with higher help should be selected. For example, yx28-820 and yx25-210-840 will choose the former, and the reverse rolling is preferred. When the thickness of the wall insulation cotton is greater than 50mm, it is not suitable to choose the corrugated board with small height, otherwise the wall surface will easily spread unevenly, which will affect the beauty of the building. When the thickness of insulation cotton is greater than 100mm, yx75-760 can be selected. When the thickness of insulation cotton is greater than 150 mm, double-layer roof shall be selected as far as possible. If yx75-760 is selected as the roof panel (note that this is a type of ignorant and sliding support connecting nailboard), even if there is no insulation requirement, we hope to add 50mm thick insulation cotton, because no insulation cotton will lead to the noise impact of roof panel and stringer, plus insulation cotton, insulation cotton production resistance support roof panel, yx75-760 link will not produce fatigue damage.

  3)根据建筑宽度和屋面坡度选择屋面板:当建筑半坡宽较大时,屋面板会产生较大的热胀冷缩应力。当半坡宽超过50m时,不宜选择yx25-210-840作为屋面板。由于这种板与屋梁是用开钉连接的,所以其拉伸能力较弱。当屋面半坡宽度大于75m时,应选用yx75-380-760板,并采用滑移支座与檩条连接,避免热应力损伤。
  3) select the roof panel according to the building width and roof slope: when the building half slope width is large, the roof panel will produce large thermal expansion and contraction stress. When the width of half slope exceeds 50m, yx25-210-840 should not be selected as roof slab. Because this kind of plate and roof beam are connected by open nails, its tensile capacity is weak. When the width of roof half slope is greater than 75m, yx75-380-760 plate shall be selected, and sliding support shall be used to connect with purlin to avoid thermal stress damage.
  4)墙板水平铺设时板材类型的选择:墙板水平铺设时,应根据建筑物的高度选择板材类型,尽量满足板宽模数。例如:墙高1.2米,屋檐高8.4米。如果选择YX25021000夹芯板,顶板切0.8m(8.4-1.2=7.2m, 7块板=0.2m),不仅浪费空间,立面效果也不好。如选用有效宽度为800mm的板材,高度限制内9块板材对墙顶好铺,能满足模数要求,不仅美观又节省板材。
  4) selection of panel type in horizontal laying of wallboard: when the wallboard is laid horizontally, the panel type shall be selected according to the height of the building to meet the width modulus of the panel as much as possible. For example: the height of the wall is 1.2m, and the height of the eaves is 8.4m. If yx25021000 sandwich plate is selected, the roof is cut 0.8m (8.4-1.2 = 7.2m, 7 plates = 0.2m), which not only wastes space, but also has poor facade effect. If the effective width of 800mm plate is selected, 9 plates within the height limit can be paved on the top of the wall, which can meet the module requirements, not only beautiful but also save the plate.
  5)圆弧板的选择:很多建筑都有造型要求,需要圆弧板,如体育馆屋顶、拱形车间屋顶等。每种类型的板都有最小的圆弧半径,所以我们应该根据屋顶的圆弧半径来选择合适的类型。
  5) selection of arc slab: many buildings have modeling requirements, and arc slab is required, such as gymnasium roof, arch workshop roof, etc. Each type of slab has the minimum arc radius, so we should choose the appropriate type according to the arc radius of the roof.
