Description

Technical Field

[0001] This utility model relates to the field of construction, specifically to a waterproof structure for the structural joint at the junction of a profiled metal roof panel and a masonry wall. Background Technology

[0002] Currently, most profiled metal roofs require structural joints at their junctions with gable walls, high-low spans, or parapet walls to separate the metal roof from the masonry wall. However, during actual construction, due to varying construction techniques, the wall surface often fails to achieve the desired flatness. Consequently, rainwater leakage easily occurs at the joints between the upturned metal flashing and the wall, leading to corrosion and deformation. Therefore, effectively and comprehensively addressing the construction issues of these structural joints becomes crucial. Utility Model Content

[0003] This utility model provides a waterproof structure for the structural joint at the junction of a profiled metal roof panel and a masonry wall, in order to solve the problems existing in the background art.

[0004] To solve the above-mentioned technical problems, the technical solution of this utility model is as follows:

[0005] A waterproof structure for the structural joint at the junction of a profiled metal roof panel and a masonry wall includes a masonry wall, a metal flashing, a metal water-stop strip, a metal roof panel, purlins, and a structural joint. A purlin is installed on one side of the masonry wall. The metal roof panel and metal flashing are screwed onto the top surface of the purlin. The metal flashing is located on top of the metal roof panel. A groove is formed in the masonry wall on one side of the purlin. The metal flashing covers the structural joint and folds up along the masonry wall to the groove, where it is folded and embedded. A metal water-stop strip is provided on the side of the metal flashing away from the masonry wall. A fixing plate is inserted into the groove. The bottom of the metal water-stop strip is turned outwards and extends beyond the bottom of the fixing plate. The fixing plate has a downwardly extending connecting portion through which a bolt passes. The bolt passes through the metal flashing and the metal water-stop strip and extends into the masonry wall for a fixed connection.

[0006] Furthermore, a bevel is provided at the connection between the top of the fixing plate and the groove.

[0007] Furthermore, the bolt is an expansion bolt, which extends into the fixing plate to form a countersunk head, and the countersunk head is filled with a metal repair agent.

[0008] Furthermore, butyl sealing tape is installed between the metal roof panel and the metal flashing for sealing.

[0009] Furthermore, the screw is a self-tapping screw, which is threadedly connected to the metal flashing, butyl sealing tape, and metal roofing panel, and extends into the purlin for threaded connection and fixation.

[0010] Furthermore, the purlin is a transverse channel steel keel structure.

[0011] Furthermore, a protective sleeve is fitted onto the top of the screw.

[0012] Furthermore, the upturn height of the metal flashing is greater than or equal to 250mm.

[0013] This utility model has the following beneficial effects:

[0014] (1) This utility model significantly improves the waterproofing effect through multiple waterproofing designs. The metal flashing is turned up and embedded in the groove of the masonry wall. This structure can effectively prevent rainwater from entering the room through the gap between the wall and the metal flashing. At the same time, butyl sealing tape is used to seal the metal flashing and the metal roof panel, which further enhances the waterproofing performance at the connection between the two. In addition, a bevel is opened at the connection between the top of the fixing plate and the groove, which can divert rainwater and prevent rainwater from flowing into the connection between the top of the fixing plate and the groove, thereby preventing rainwater from seeping into the gap between the masonry wall and the metal flashing. This multi-layered waterproofing structure works together to provide reliable waterproof protection for the interior of the building, effectively avoiding problems such as indoor dampness and wall damage caused by rainwater leakage, and extending the service life of the building.

[0015] (2) This utility model uses expansion bolts to tightly fix the fixing plate, metal flashing, and metal water-blocking strip, and integrates them with the masonry wall to form a stable and reliable overall structure. This ensures that the components will not loosen or shift during long-term use, thereby maintaining the integrity and effectiveness of the waterproof structure. On the other hand, to increase the service life of the components, the countersunk head formed by the expansion bolts extending into the fixing plate is filled with metal repair agent, and a protective sleeve is fitted on the top of the screw. This effectively isolates the components from external rainwater erosion and air oxidation, avoiding problems such as structural loosening and waterproof failure caused by rust or corrosion of the components; it not only extends the service life of the components and reduces the need for frequent replacement due to component damage, but also reduces the later maintenance costs and workload.

Figure 1-3 As shown, the structure includes a masonry wall 1, a metal flashing 2, a metal water-blocking strip 3, a metal roof panel 4, purlins 5, and a structural joint 6. A purlin 5 is installed on one side of the masonry wall 1. The purlin 5 uses a transverse channel steel keel structure. The metal roof panel 4 and the metal flashing 2 are installed on the top surface of the purlin 5 using screws 10. The metal flashing 2 is located on top of the metal roof panel 4. Butyl sealing tape 14 is installed between the metal roof panel 4 and the metal flashing 2 to seal and prevent rainwater from entering. In this embodiment, the screws 10 are self-tapping screws, which are threaded to the metal flashing 2, the butyl sealing tape 14, and the metal roof panel 4, and extend into the purlin 5 for threaded connection and fixation. A groove 7 is formed on one side of the masonry wall 1 near the purlin 5. The metal flashing 2 covers the structural joint 6 and folds up along the masonry wall 1 to the groove 7, where it is folded and embedded. The folding height of the metal flashing 2 is greater than or equal to... The 250mm width prevents rainwater from entering the gap between the wall and the metal flashing 2. A metal water-blocking strip 3 is provided on the side of the metal flashing 2 away from the masonry wall 1. A fixing plate 8 is inserted into the groove 7. The bottom of the metal water-blocking strip 3 is turned outwards and extends beyond the bottom of the fixing plate 8, allowing external rainwater to be introduced onto the metal roof panel 4 through the metal water-blocking strip 3. The fixing plate 8 has a downwardly extending connecting part, through which a bolt 9 passes. The bolt 9 passes through the metal flashing 2 and the metal water-blocking strip 3 and extends into the masonry wall 1 for fixed connection. In this embodiment, the bolt 9 is an expansion bolt. The fixing plate 8 uses the expansion bolt 9 to fix the metal flashing 2 and the metal water-blocking strip 3 together with the masonry wall 1, forming a stable and reliable whole. It should be noted that the waterproof structure of this utility model is applicable to gable walls, high and low spans, or parapet walls.
