Embodiment 2

[0025] A construction process of the anti-cracking waterproof structure at the joint between the decorative line and the wall of the present invention comprises the following steps:

[0026] Step 1. Pop up the control line at the elevation of the finished decorative line 5 on the outside of the outer wall 6, reserve the installation position of the finished decorative line 5, and reserve a 300mm outer wall plaster layer 1 at the installation position of the finished decorative line 5 s position;

[0027] Step 2: When the upper external wall painting layer 1 is painted to the position where the finished decorative line 5 is to be installed, install the finished decorative line 5, and align the vertical and horizontal gaps of the finished decorative line 5 with the ink line to keep the width of the gap consistent. Line 5 must be installed horizontally and vertically, within the allowable tolerance range, to ensure that the finished decorative line 5 is free from damage, missing ...

Abstract

The invention discloses an anti-cracking waterproof structure at a joint of a decorative moulding and a wall body. The anti-cracking waterproof structure comprises an outer wall and a finished product decorative moulding arranged on the outer side of the outer wall, and the anti-cracking waterproof structure is arranged at the joint of an upper opening internal corner of the finished product decorative moulding and the outer wall; a round corner is arranged at the joint of the upper opening internal corner of the finished product decorative moulding and the outer wall through mortar; a coating waterproof layer is arranged on the outer side of the round corner; alkali-resisting gridding cloth is arranged on the outer side of the coating waterproof layer, and an outer wall painting layer is arranged on the outer side of the alkali-resisting gridding cloth. The invention further discloses a construction process of the anti-cracking waterproof structure. The problems of wall leakage and damp conditions in freezing periods of rainstorm, rain and snow due to cracking and falling caused by thermal expansion and cold contraction and the like of a connecting internal corner part of the decorative moulding and the wall body can be effectively solved, the cost is low, the effect is good, and the practicability is high.

Description

technical field [0001] The invention belongs to the technical field of building construction, and in particular relates to a crack-proof and waterproof structure at the joint between decorative lines and walls and a construction process. Background technique [0002] In the field of high-rise building construction, in order to ensure that the structure avoids the singleness and reflects its own difference and symbolism, decorative lines are often set on the iconic floors of the facade of the structure; because the lines are in different forms and sizes; there are once The structural lines of the structure and the decorative lines of the finished products also exist such as finished GRC, EPS boards and other materials; as for the exterior wall lines protruding a lot in the design, because they cannot meet the installation requirements of the scaffolding, it is often chosen to carry out the finished line after the main structure is completed. Install. This is very easy to cau...
