AI Technical Summary
The existing expansion joint cover plates are insufficient or too large when connecting, resulting in gaps or raising in the sky-facing joints, and rainwater leaks into the room, causing problems such as exterior wall leakage and interior wall damage.
Set drip lines on the upper side of the seam facing the sky, and apply grid cloth, exterior wall putty and paint on the outside, and cover butyl waterproof tape on the inside to form a double protection to prevent rainwater from leaking.
Through the combination of drip lines and butyl waterproof tape, rainwater is effectively prevented from flowing into the exterior wall along the seams towards the sky, avoiding leakage of the exterior wall causing damage to the interior, achieving a dual protection effect.

Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of building materials, in particular to a combined drip line for exterior wall construction. Background Art
[0002] Exterior wall waterproofing is directly related to the quality of the living experience. With the advancement of large-scale infrastructure construction in cities, the exterior wall waterproofing of new buildings has received increasing attention, especially in southern my country, where the rainy season is long and the exterior walls are in contact with rainwater for a long time, which increases the chance of water seepage. In order to prevent cracks in the walls of two adjacent buildings due to large settlement of one building, a gap is left between the two adjacent buildings during construction. After the completion of the two buildings, expansion joint covers are installed on the outside of the exterior wall paint using expansion screws to complete the sealing of the gap between the two adjacent buildings, preventing rainwater from flowing into the gap between the two buildings, causing rainwater to seep into the room and avoid damage to the wall.
[0003] When the existing expansion joint cover plate is penetrated from the outside to the inside by expansion screws, the paint, exterior wall putty and mesh cloth in sequence and connected to the vertical wall, if the compression force of the expansion screw is too small, it is easy to cause the expansion joint cover plate and the paint on the outside of the vertical wall to not fit together completely, resulting in a small gap. If the compression force of the expansion screw is too large, it is easy to cause the top of the expansion joint cover plate to tilt up, resulting in an upward gap between the top of the expansion joint cover plate and the paint. When it rains, rainwater can easily flow along the paint on the outside of the vertical wall through the upward gap into the gap between the two buildings. Because the expansion joint cover plate is installed on the top between the two buildings, the rainwater flowing into the gap cannot evaporate, and will still cause leakage to the vertical wall and damage the interior wall of the room. Utility Model Content

[0014] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.
[0015] like Figure 1-3 As shown, a combined drip line for exterior wall construction includes a first wall 1 arranged horizontally, combined with Figure 1 As shown, a vertical second wall 2 is provided at one side of the first wall 1, and an expansion joint cover 3 is fixedly provided between the top of the first wall 1 and the side wall of the second wall 2. Figure 1 and Figure 2 As shown, both ends of the expansion joint cover plate 3 are provided with expansion screws 4 for fixing the expansion joint cover plate 3 on the top of the first wall 1 and the side wall of the second wall 2 respectively. After the expansion joint cover plate 3 is fixed by the expansion screws 4 on the second wall 2, a ceiling seam 5 is formed between the top of the expansion joint cover plate 3 and the second wall 2. A drip line 6 is fixed on the side wall of the second wall 2 and located on the upper side of the ceiling seam 5. The outside of the drip line 6 is provided with a mesh cloth 7, exterior wall putty 8 and paint 9 in sequence. The inner side of the drip line 6 and the outer side of the expansion joint cover plate 3 are provided with a butyl waterproof tape 10 for covering the ceiling seam 5.
[0016] Further, combined Figure 2 and Figure 3 As shown, the drip line 6 includes a straight section 601 in contact with the outer wall of the second wall 2, and the outer side of the straight section 601 is sequentially provided with a mesh cloth 7, exterior wall putty 8 and paint 9. The bottom end of the straight section 601 is inclined outwardly to provide an inclined section 602, and the bottom end of the inclined section 602 is fixedly provided with a bent section 603. One end of the butyl waterproof tape 10 is adhered to the inner side of the inclined section 602. Preferably, the setting of the bent section 603 prevents rainwater from dripping from the bottom end of the inclined section 602 from contacting the butyl waterproof tape 10, thereby affecting the firmness of the butyl waterproof tape 10 on the inner side of the inclined section 602. The other end of the butyl waterproof tape 10 extends to the lower side of the ceiling seam 5.
[0017] Preferably, a drip line 6 for covering the upward seam 5 is provided on the vertical second wall 2 and on the upper side of the upward seam 5, and a mesh cloth 7, exterior wall putty 8 and paint 9 are provided in sequence from the inside to the outside on the outside of the drip line 6.

The setting of the drip line 6 and the butyl waterproof tape 10 provides double protection for the upward seam 5 to prevent rainwater from flowing into the second wall 2 along the upward seam 5, causing leakage of the exterior wall to damage the interior wall of the room.
[0018] Working principle:
[0019] First, fix one end of the expansion joint cover 3 on the top of the first wall 1 with the expansion screw 4, and then fix the other end of the expansion joint cover 3 on the outer side wall of the second wall 2 with the expansion screw 4. Then, evenly apply mortar on the outer side wall of the second wall 2 and on the upper side of the skylight 5, and make the straight section 601 of the drip line 6 contact with the applied mortar. Then, scrape and level the mortar on the outside of the straight section 601, and fix the drip line 6 on the outer side of the second wall 2 with the mortar. On the wall, after the drip line 6 is fixed, a mesh cloth 7, exterior wall putty 8 and paint 9 are arranged in sequence on the outside of the straight section 601, and then a butyl waterproof tape 10 is pasted on the inside of the inclined section 602. The other end of the butyl waterproof tape 10 is extended to the outside of the expansion joint cover 3, and the upward seam 5 is covered by the butyl waterproof tape 10, and the upward seam 5 is blocked by the drip line 6. The drip line 6 and the butyl waterproof tape 10 provide double protection for the upward seam 5 to prevent rainwater from flowing into the upward seam 5.
