Detailed Description
The present application is described in further detail below with reference to the attached drawings.
Referring to fig. 1 and 2, for this application discloses an indoor reentrant corner waterproof construction, including setting gradually at reentrant corner surperficial waterproof cement arc layer 1 that smears, first waterproof coating layer 2, waterproof glue layer 3, net cloth 4, a plurality of layers of second waterproof coating layer 5, cement mortar protective layer 6.
The waterproof cement arc-smearing layer 1 is smeared at the end corner of the internal corner by adopting polymer cement mortar, the surface of the waterproof cement arc-smearing layer 1 departing from the internal corner is an arc surface, and the two ends of the arc surface are respectively tangent with the wall surface 9 and the ground surface 8. The radius of the arc surface of the waterproof cement arc-smearing layer 1 is 10-20 mm. Thereby make waterproof cement smear the gap between the arc layer 1 can be abundant 8 and the wall 9 on the one hand fill, on the other hand makes waterproof cement layer can not be too thick to the ceramic tile is applied to wall 9 in the later stage has been made things convenient for.
When the waterproof cement layer is completely dried, a worker coats the first waterproof coating layer 2 on the outer side of the waterproof cement arc-smearing layer 1. Waterproof coating is and covers simultaneously at wall 9, and arc layer 1 is smeared to waterproof cement, on 8 ground, waterproof coating's one side height with the wall 9 laminating is not less than 150mm, and waterproof coating is apart from wall 9 with one side of 8 laminating on ground and is not less than 150mm cover when wall 9 and ground 8 through waterproof coating for waterproof coating forms the protective layer wholly and covers the surface on arc layer, thereby improved the waterproof performance of reentrant corner department. When the first waterproof coating layer 2 is coated, a worker needs to press the waterproof coating layer to be thin, and the thickness of the first waterproof coating layer 2 is enabled to be perpendicular to 1-2mm through repeated hanging and pressing, so that the condition that the coating layer is cracked due to nonuniform shrinkage of the inner layer and the outer layer of the coating caused by over-thickness of the coating layer is reduced; the setting of first waterproof coating layer 2 can also completely cut off the steam in the wall, has reduced because 9 of the wall get damp, and steam gets into waterproof glue film 3 to influence the condition of 3 bonding effects of waterproof glue film.
As shown in fig. 3, the net cloth 4 adopts the glass fiber net cloth, the setting of net cloth 4 connects the first waterproof coating layer 2 and the second waterproof coating layer 5, thereby providing a flexible framework for the whole waterproof layer, improving the resistance of the whole waterproof layer to external force, and bonding with the waterproof coating layers of all positions through the net cloth 4, so that the waterproof coating layers of different positions are connected into a whole, thereby reducing the occurrence of the condition that the waterproof layer cracks to influence the waterproof effect. The grid cloth 4 is laid on the wall surface 9 and the ground 8 at the same time, the length of the grid cloth 4 laid on the wall surface 9 is not less than 150mm, and the length of the grid cloth 4 laid on the bottom surface is not less than 150mm. The limitation of the lengths of the two ends of the mesh cloth 4 improves the action area of the mesh cloth 4, so that the waterproof cement arc coating layer 1 is fully protected, the waterproof effect is improved, the two ends of the mesh cloth 4 have enough lengths and are bonded with the waterproof glue layer 3, and the stability of fixing the mesh cloth 4 is improved; and the water vapor is not easy to permeate into the waterproof cement arc-smearing layer 1 through the side edges of the mesh cloth 4, thereby improving the waterproof stability.
