屋面变形缝的防水做法

  变形缝共有2种分别为:高低变变形缝有高低变形缝和等高变形缝;等高变形缝又分为高出屋面等高变形缝、与屋面平齐变形缝和双天沟变形缝等三种。在挡水墙底部处防水涂层及嵌缝材料脱落或被拉裂清理干净后刮填嵌缝材料,表面做一布两涂加强层,该部位的地方防水涂层及嵌缝材料老化、龟裂。
A total of 2 deformation cracks respectively: high and low deformation joints have high and low deformation joints and contour deformation joints; High seam deformation is divided into above roof contour deformation cracks, flush with the roof deformation cracks and three double seam roof gutter deformation, etc. In water retaining wall at the bottom of the waterproof coating and sealing material fall off or be ripping cleaned up after filling sealing material, the surface of the two do a cloth strengthening layer, the part of the local waterproof coating and sealing materials and chapping.
  高低变形缝的一边为立墙(高层),另一侧为屋面。这时屋面防水层如为卷材时,卷材应钉压在高层墙顶上,并向缝中下凹,上面采用合成高分子卷材一边钉压在高层墙顶上,一边直接粘到屋面防水层上,同时在表面用金属板单边固定予以保护。比如在屋面涂膜防水层时,也应采用与卷材防水层相同的方法处理,并做好涂膜防水层与合成高分子卷材的搭接。
High and low distortion seam to stand on one side wall (top), on the other side for the roof. The roofing waterproof layer such as coil, coil nail should be on the top of the pressure in the upper wall, seam and lower concave, above the synthetic polymer coil nail on the top of the pressure in the upper wall, side stick directly to the roofing waterproof layer, at the same time shall be protected in unilateral fixed surface with a metal plate. When such as roofing waterproof layer coating, also should use the same as the coiled material waterproof layer method of treatment, and coating waterproof joints with the synthetic polymer coil.
  对于等高变形缝的高出屋面变形缝或双天沟变形缝,防水层均应做到高出屋面矮墙或天沟侧壁的顶面,然后在上面的用合成高分子卷材覆盖,卷材中间下凹到变形缝内,再凹槽内垫聚乙泡沫条,两边与屋面上翻的防水层搭接,然后再在顶部铺一层合成高分子卷材,两边应覆盖住前一层合成高分子卷材的搭接缝;上部再用细石混凝土或不锈钢盖板盖压这样就可以做到防水的目的了。
For contour distortion seam above the roof deformation cracks or double seam roof gutter deformation, waterproof layer should be higher than that of low wall or roof gutter sidewall top surface, and then in the above cover, with synthetic polymer coil coil concave to the deformation cracks in the middle, mat polyethylene foam article, and the slots on both sides and on the roof waterproof layer of the lap, and then put a layer of synthetic polymer coil at the top, both sides should be before covering a layer of synthetic polymer coil lap seam; The upper with a fine stone concrete or stainless steel plate cover pressure so that you can do the waterproof purpose.
