[0031] The specific implementation of the present application is described in detail below in conjunction with the accompanying drawings. It should be understood that the specific implementation described here is only used to illustrate and explain the present application, and is not used to limit the present application.

[0032] The present application will be described in detail below with reference to the accompanying drawings and in conjunction with exemplary embodiments.

[0033] like Figure 1 As shown, the first exemplary embodiment of the present application provides a roof repair structure, which includes a ring beam 1, a parapet 2, an outer boundary groove 3, a boundary waterproof structure 4 and a first waterproof coating layer 5. Among them, the parapet 2 is connected to the top of the ring beam 1, and the main structure of the parapet 2 is a masonry structure 201; the outer boundary groove 3 is formed at the junction of the root outer wall of the masonry structure 201 and the top outer wall of the ring beam 1; the boundary waterproof structure 4 is filled in the outer boundary groove 3 to seal the outer boundary groove 3; the first waterproof coating layer 5 covers the outer side surface, top surface and inner side surface of the parapet 2.

[0034] It can be seen that the roof repair structure of this exemplary embodiment is able to effectively repair the junction cracks caused by structural stress by setting an outer junction groove 3 at the junction of the parapet 2 and the ring beam 1, and filling the outer junction groove 3 with a junction waterproof structure 4, so as to make the junction between the parapet 2 and the ring beam 1 more sealed. In addition, the surrounding wall of the entire parapet is covered by the first waterproof coating layer, which further effectively improves the overall waterproof effect and effectively prevents the parapet 2 from cracking and leaking due to stress.

[0035] Specifically, the interface waterproof structure 4 includes a caulking agent layer, a first waterproof mortar layer and an interface finishing layer which are sequentially arranged from the inside to the outside, wherein the caulking agent layer can be a butyl mastic layer, and the first waterproof mortar layer is used to smooth the butyl mastic layer to further improve the waterproof effect. The parapet 2 also includes a parapet finishing layer arranged on the surface of the masonry structure 201, and the ring beam 1 includes a ring beam finishing layer arranged on the surface of the ring beam. In order to further improve the flatness of the roof exterior wall, when the interface finishing layer covers the first waterproof mortar layer, the ring beam finishing layer, the interface finishing layer and the parapet finishing layer are required to be sealed and connected in sequence, so that the repaired interface is flat and seamless, which effectively improves the aesthetics of the building.

[0036] In an optional or preferred embodiment, the outer boundary groove 3 is formed as a V-shaped groove, and the boundary waterproof structure 4 is formed as a V-shaped structure that cooperates with the V-shaped groove. When the boundary waterproof structure 4 is filled in the outer boundary groove 3, the outer side surface of the boundary waterproof structure 4, the outer side surface of the ring beam 1 and the outer side surface of the parapet 2 are vertically flush.

[0037] exist Figure 1 In the illustrated embodiment, the first waterproof coating layer 5 also covers the outer side surface of the junction waterproof structure 4 and extends downward to the outer side surface of the ring beam 1, thereby improving the waterproof ability of the entire outer side surface of the roof structure, especially the two junction positions of the junction waterproof structure 4 and the parapet 2 and the ring beam 1, further improving the protective effect of the junction waterproof structure 4 on the junction of the parapet 2 and the ring beam 1.

[0038] On the inner side of the parapet 2, the roof repair structure includes a floor structure 6 and a counter sill 7, wherein the floor structure 6 is connected to the lateral inner end of the ring beam 1, and the counter sill 7 is arranged at the inner corner between the masonry structure 201 and the floor structure 6. Figure 1 In the illustrated embodiment, the portion of the first waterproof coating layer 5 covering the inner side surface of the parapet 2 does not extend beyond the connection between the anti-ridge 7 and the inner side surface of the parapet 2. In other words, the portion of the first waterproof coating layer 5 covering the inner side surface of the parapet 2 extends downward to the top surface of the anti-ridge 7. In this way, it can be ensured that the first waterproof coating layer 5 can cover the waterproof structure such as a water cut-off trough arranged on the inner side surface of the parapet 2.

[0039] In an optional or preferred embodiment, referring to Figure 1The roof repair structure also includes a masonry water cut-off trough 9, a floor water cut-off trough 10 and a composite waterproof layer 8, wherein the masonry water cut-off trough 9 is formed on the inner side surface of the masonry structure 201 located above the anti-ridge 7, and the floor water cut-off trough 10 is formed on the top surface of the floor structure 6 located on the lateral side of the anti-ridge 7.

[0040] It should be noted that when the anti-ridge 7 is provided, the inner angle between the masonry structure 201 and the floor structure 6 is transformed into an outer angle. In order to carry out wrapping waterproof construction on the outer angle, the composite waterproof layer 8 can be covered on the surface of the anti-ridge 7, and the two ends of the composite waterproof layer 8 at least extend to the masonry water cut-off groove 9 and the floor water cut-off groove 10 respectively, so that the composite waterproof layer 8 can cover part of the surface of the masonry structure 201 and the floor structure 6, thereby covering the junction between the masonry structure 201 and the anti-ridge 7 and the junction between the floor structure 6 and the anti-ridge 7.

[0041] In this embodiment, the composite waterproof layer 8 includes a cement mortar layer, a second waterproof mortar layer, a second waterproof coating layer, a new waterproof membrane 801 and a concrete protective layer 802 which are sequentially layered from the inside to the outside, wherein one end of the new waterproof membrane 801 is closed in the masonry water cut-off groove 9, and the other end is closed in the floor water cut-off groove 10, the concrete protective layer 802 covers the masonry structure 201 at least to the masonry water cut-off groove 9, and the first waterproof coating layer 5 covers the inner side surface of the parapet 2 at least to the concrete protective layer 802 corresponding to the masonry water cut-off groove 9.

[0042] In addition, the roof repair structure of this embodiment also includes an old waterproof membrane 11 arranged on the side of the floor water cut-off groove 10 away from the anti-ridge 7. The old waterproof membrane 11 can be an old waterproof membrane retained in the original roof waterproof layer, which is used to overlap the new waterproof membrane 801 to cover the floor water cut-off groove 10, so that the floor water cut-off groove 10 is more sealed and the waterproof effect is better.
