| 外墙外保温做法主要有：在承重墙体的外侧粘贴(钉、挂)膨胀型聚苯乙烯板(EPS)、挤塑型聚苯乙烯板(XPS)，聚氨酯硬泡喷涂(PUR)和粉刷胶粉聚苯颗粒保温砂浆等。挤塑型XPS聚苯板和聚氨酯硬泡喷涂的价格稍高，目前应用最多的是膨胀型EPS聚苯板外保温。 The main methods of exterior wall external insulation include: sticking on the outside side of the load-bearing wall, expanding polystyrene board (EPS), extruding polystyrene board (XPS), polyurethane rigid foam spraying (PUR) and plaster powder, polystyrene particle insulation mortar, etc. The price of extruded XPS polystyrene board and polyurethane rigid foam is slightly higher, and the most widely used is the external thermal insulation of the expanded EPS polystyrene board. xps挤塑板喷砂 XPS extrusion plate sand blasting 1 EPS板的打磨 Grinding of 1 EPS plate EPS板粘贴固定后需静置24h才能进行打磨，以防EPS板移动。打磨用专用的搓抹子将板边的不平之处磨平，消除板间接缝的高低差，打磨时散落的EPS碎屑随时清理干净。板缝间隙＞1.6mm时应用EPS板条填实后磨平。 After the EPS board is fixed and fixed, the 24h is required to be grinded in order to prevent the movement of the EPS board. Polished by special float plate edge will rub uneven surface, remove the plate joints between the height difference, abrosive scattered debris to clean up the EPS at any time. Application of EPS > 1.6mm seam gap filling after polished slab. 2 网格布的铺设 The laying of 2 mesh cloth 通常采用二道抹面砂浆法。用不锈钢抹子在EPS板表面均匀涂抹面积略大于一块网格布的抹面砂浆，随即将网格布压入抹面砂浆中，待砂浆稍干至可碰触时，立即用抹子涂抹第二道抹面砂浆,将网格布埋在两道抹面砂浆的中间。全部抹面砂浆和网格布铺设完毕后，静置养护3d，方可进行下一道工序的施工。 Usually use two mortar method. Daub mortar is slightly larger than the area of a piece of fiberglass mesh in EPS stainless steel plate surface is uniform with trowel, grid cloth pressed into the mortar in the mortar, to be slightly dry to the touch, immediately smear second mortar with a trowel, grid cloth buried in two mortar in between. All mortar and mesh laying is completed, static maintenance 3D, before the construction of next working procedure. 3饰面层的选择 3 choice of face layer EPS复合式外墙保温层属于轻质、柔性的保温构造,饰面材料采用涂料属“柔-柔”搭配，外保温体系自重约10kg/m2；而磁砖面层外保温自重可达50kg/m2以上，即便用附加锚栓或埋入法来确保磁砖与保温层间的附着安全性，但“柔性基底-刚性面层”的构造缺陷仍然明显，磁砖背面的冷凝水易发生冻融破坏，温湿应力导致砖缝处面层开裂较难避免。EPS复合式外墙保温层的饰面层应优先选用高弹性涂料，饰面材料为石材应采用“干挂法”施工。 Layer insulation structure belongs to the lightweight, flexible EPS composite wall insulation decorative materials, the use of paint is a "soft - soft" collocation, external insulation system weight about 10kg/m2; while the tile surface layer of external insulation above the weight of up to 50kg/m2, even with additional anchor bolt or embedded method to ensure that the insulation layer between the tile and the attachment security but, "the structural defects in rigid flexible substrate surface layer" is still evident, the condensed water on the back of the tile is prone to freeze-thaw damage, temperature and humidity stress causes the brick joint surface layer is difficult to avoid. High elastic coatings should be preferred in the veneering layer of EPS composite exterior wall insulation, and "dry hanging" construction should be adopted for the decoration material. 4门窗洞口及阳角的处理 Treatment of 4 door and window opening and yang angle 门窗洞口角部的聚苯板，应采用整块聚苯板切割出洞口，不得用碎(小)块拼接。铺设网格布时，应在洞口四角处沿450方向贴补一块标准网格布(200×300mm)，以防止角部开裂。 The polystyrene board in the corner of the door and the door of the door and window should be cut out by the whole block of polystyrene board, and it should not be spliced with broken (small) blocks. The laying of mesh cloth, should be around the four corners along the 450 direction with a standard mesh (200 * 300mm), in order to prevent the corner crack. xps挤塑板喷砂 XPS extrusion plate sand blasting |
