挤塑板的表面分析情况!

  挤压后的板材表面不应油腻且大量积水,并应清除表面的水泥浆和浮灰。施工过程中,腻子刮板应使用将准备好的橡胶材料刮到厚度为1mm的挤塑板表面。压力要均匀,使橡胶材料均匀地分布在挤出塑料板的表面。挤出板之间的间隙应小于或等于3mm,水泥膏体嵌入的间隙应大于或等于10mm。挤出板之间的间隙用NP中性硅胶密封剂或JS挤出板界面剂填充。
After extrusion, the surface of the extruded sheet should not be greasy and plenty of water accumulated, and the cement slurry and floating ash on the surface should be removed. During construction, putty scrapers should be scraped onto the surface of extruded plastic sheets with a thickness of 1 mm using prepared rubber materials. The pressure should be uniform so that the rubber material is evenly distributed on the surface of the extruded plastic sheet. The clearance between extrusion plates should be less than or equal to 3 mm, and the clearance embedded in cement paste should be greater than or equal to 10 mm. The gap between the extrusion plates is filled with NP neutral silica gel sealant or JS interface agent.
挤出板的外模板和外模板就位后,根据螺栓穿过外模具壁的位置,用挤出板开孔器将挤出板打孔。挤板开孔器应旋转向前推,确保孔的大小,以免对挤板造成损坏。开孔后安装拉杆和套管。将外墙内模板置于预定位置,按常规方法关闭模板。挤塑保温板垂直排到门窗上,根据需要在外墙水平绑上,使其不出现窄条。l型镀锌铁皮应置于外模上底板的厚度范围内,可保护保温板的上边缘,防止混凝土填充到挤制地板截面的鸽尾槽内。后消除了内部和外部的模板,支持底板钢筋模板和领带,并安装外墙辅助模板使用外墙穿孔螺栓,也就是说,挤塑板和辅助外部模板一起玩底板侧模板的作用。浇注楼板混凝土时,将混凝土填入挤出板的燕尾槽内,楼板与挤出板形成咬合连接。拆除辅助模板后,整个挤压板与外墙融为一体,形成外墙外保温层。

After the external template and the external template of the extrusion plate are in place, according to the position of the bolt passing through the external die wall, the extrusion plate is perforated with the extrusion plate opener. The extruder should be rotated and pushed forward to ensure the size of the hole, so as not to cause damage to the extruder. Install pull rod and casing after opening. Put the template inside the outer wall in a predetermined position and close the template according to the conventional method. The extruded insulation board is arranged vertically on the doors and windows, and tied horizontally on the external wall according to the need, so that it does not appear narrow strips. Type l galvanized iron sheet should be placed within the thickness range of the upper and bottom plates of the exterior die, which can protect the upper edge of the insulation board and prevent concrete from filling into the pigeon tail groove of the extruded floor section. After eliminating the internal and external templates, supporting the steel template and tie of the floor, and installing the auxiliary template of the external wall, using the perforated bolts of the external wall, that is to say, the Extrusion board and the auxiliary external template play the role of the side template of the floor together. When pouring the floor concrete, the concrete is filled into the dovetail trough of the extruded slab, and the floor is occluded with the extruded slab. After removing the auxiliary formwork, the Extrusion board and the external wall are integrated to form an external thermal insulation layer.

如果挤压板在外壁上有部分损伤,则将其轮廓切成矩形,并用挤压板绕圆覆盖JS界面剂的对应形状。取下辅助模板后,应及时用界面剂刮除挤出板。水泥砂浆污染的挤出板表面,在刮除JS挤出板界面剂前,应先用粗砂纸清理干净。在季节性施工中,挤塑板可以起到保温和保温的作用。但当环境温度低于5℃时,挤压板表面应使用防冻js-2挤压板界面剂进行刮擦,技术指标应达到-15℃。在雨季,js-1挤压板界面剂应刮擦在挤压板表面,刮擦应在无明水状态下进行。如果在炎热的阳光下,挤出板表面应用湿布擦拭,略湿干燥。刮接剂,适当遮光,刮完后,对表面进行初步硬化,应喷施4h喷淋养护。
If the extrusion plate has some damage on the outer wall, the contour of the extrusion plate is cut into rectangles and the corresponding shape of JS interfacial agent is covered by the extrusion plate around a circle. After removing the auxiliary template, the extrusion plate should be scraped with interfacial agent in time. Before scraping JS Extrusion board interface agent, the surface of Extrusion board contaminated by cement mortar should be cleaned with coarse sand paper. In seasonal construction, Extrusion board can play a role of heat preservation and insulation. However, when the ambient temperature is lower than 5 C, the surface of extrusion plate should be scraped with anti-freezing JS-2 extrusion plate interface agent, and the technical index should reach - 15 C. In rainy season, the interface agent of JS-1 extrusion plate should be scraped on the surface of the extrusion plate, and the scraping should be carried out in the absence of clear water. If in the hot sunshine, the Extrusion board surface should be wiped with a wet cloth, slightly wet and dry. Scraping agent, appropriate shading, after scraping, the surface of the initial hardening, should be sprayed for 4 hours spraying maintenance.
