Description

Technical Field

[0001] The invention relates to the technical field of building drainage engineering, in particular to a stainless steel roof rainwater overflow outlet structure and an installation process thereof. Background Art

[0002] According to the requirements of the "Building Water Supply and Drainage Design Standard" GB50015-2019, overflow facilities such as overflow holes or overflow pipes should be installed in building roof rainwater drainage projects. The purpose of the setting is that when the roof drainage system cannot drain the roof rainwater in time and the accumulated water reaches a certain depth, the excess rainwater can be discharged from the overflow port. Its forms include: metal gutter overflow holes, wall square hole overflow ports, wall round pipe overflow ports, funnel-shaped overflow pipes, and straight pipe overflow pipes. Among them, the wall square hole overflow port is the most commonly used because of its convenient construction and large drainage capacity. Furthermore, because the overflow port processed by stainless steel thin plates has the advantages of light weight, no rust, no leakage, easy processing, and long service life, it is often used to make wall square hole overflow ports;

[0003] The existing stainless steel overflow structure has many problems during actual installation. The main problems are as follows:

[0004] 1. The overflow cover is too small, smaller than the reserved hole of the structure, and cannot effectively close the reserved hole of the structure completely. At the same time, it is difficult to temporarily fix it during construction;

[0005] 2. The sealing problem between the outside of the overflow port and the structural opening cannot be solved;

[0006] 3. The problem of waterproof continuity between the inner side of the parapet and the inner side of the overflow port has not been solved;

[0007] 4. The rainwater grate fixed with bolts needs to have an opening on the waterproof membrane, which may cause leakage;

[0008] 5. The installation process is imperfect and the appearance quality is poor.

[0009] The installation is inconvenient, the fixation is not firm, and there is a risk of leakage at the overflow port. For this reason, we have improved the above-mentioned existing technology based on actual usage. Summary of the invention

[0032] Among them, preferably, a 4mm metal composite panel is connected to the outer wall of the metal composite panel curtain wall 6, and the right side of the metal composite panel curtain wall 6 is connected to the reinforced concrete parapet 5 through a vacuum insulation panel 14, the right side of the reinforced concrete parapet 5 is connected to an SBS waterproof membrane 9, and the right side of the SBS waterproof membrane 9 is connected to an extruded polystyrene board insulation layer 10, and the right side of the extruded polystyrene board insulation layer 10 is connected to a PVC waterproof membrane 11, and the position where the PVC waterproof membrane 11 contacts the stainless steel sealing plate 2 is connected to an overflow port PVC waterproof membrane additional layer 12, and the inner wall of the stainless steel overflow pipe 1 is bonded with the PVC waterproof membrane 11.

[0033] Preferably, a reserved hole 7 matching the stainless steel overflow pipe 1 is provided on the metal composite panel curtain wall 6 and the reinforced concrete parapet 5, a weather-resistant sealing layer 8 is provided at the connection between the stainless steel overflow pipe 1 and the metal composite panel curtain wall 6, and a polyurethane foaming agent layer 13 is provided in the reserved hole 7.

[0034] An installation process for a stainless steel roof rainwater overflow structure, the installation process comprising the following steps:

[0035] S1. During the construction of the main structure, a reserved opening 7 is reserved on the reinforced concrete parapet 5. Usually, the size of the reserved opening 7 is 50 mm larger than each side of the overflow structure, so as to facilitate the appropriate adjustment of the position of the overflow structure in the later stage. The width of the stainless steel sealing plate 2 is widened to 80 mm so that it can completely cover the structural opening. The process is improved. The PVC waterproofing membrane 11 on the reinforced concrete parapet 5 is first constructed, so that the stainless steel sealing plate 2 can be pasted on the PVC waterproofing membrane 11 to play a temporary fixing role, which solves the problem that the traditional overflow sealing plate (i.e., the stainless steel sealing plate 2) is too small, smaller than the reserved structural opening (reserved opening 7), and the reserved structural opening cannot be effectively completely closed, and it is difficult to temporarily fix it during construction;

[0036] S2. Before the overflow structure is constructed, check the hole condition, remove the obstructions in the hole, unify the elevation of the overflow, and trim the inside of the hole; if there is a metal composite panel curtain wall 6 on the exterior wall, check whether there is a conflict between the hole and the keel of the metal composite panel curtain wall 5. If there is a conflict, the conflict can be resolved by appropriately adjusting the overflow structure position or expanding the reserved hole 7 of the structure. However, in principle, the height difference between the bottom of the overflow structure and the roof should be kept between 150mm and 200mm.

[0037] S3. After the opening is repaired, the extruded polystyrene board insulation layer 10, the PVC waterproof membrane 11 and the metal composite panel curtain wall 6 are constructed.

[0038] S4. Install the overflow port for trial installation and confirm the position of the hole on the metal composite panel curtain wall 6. Drill a hole on the metal composite panel curtain wall 6 with a size 5 mm larger than one side of the overflow port structure.

[0039] S5. Install the overflow structure, apply weather-resistant glue to the stainless steel sealing plate 2, insert the overflow structure into the reserved hole 7 on the wall from one side of the roof, paste the stainless steel sealing plate 2 on the PVC waterproof membrane 11 on the inner side of the reinforced concrete parapet 5, and adjust the level; the metal composite panel curtain wall 6 is extended outward from the overflow structure, and the opening of the metal composite panel curtain wall 6 is sealed with weather-resistant glue around to obtain a weather-resistant sealing layer 8. After the weather-resistant glue inside and outside is completely dry, inject the polyurethane foaming agent from the four foaming agent injection ports 4 reserved on the stainless steel sealing plate 2 to fill the gap between the overflow structure and the reserved hole 7, and finally fix the overflow structure, thereby solving the sealing problem;

[0040] S6, make an additional layer 12 of PVC waterproofing membrane for the overflow port, the inner side of the overflow port structure is covered with the additional layer 12 of PVC waterproofing membrane for the overflow port, and then turned out from the inner side of the overflow port structure to overlap with the PVC waterproofing membrane 11 on the wall, thereby eliminating the problem of water seepage of the stainless steel overflow port structure;

[0041] S7. Install the stainless steel grate 3, apply weather-resistant glue on the inner side of the stainless steel grate 3, insert it into the inner side of the stainless steel overflow pipe 1 and bond it firmly to avoid the hidden danger of water leakage caused by opening holes in the PVC waterproof membrane 11, and avoid the problem of leakage caused by the opening of the traditional rainwater grate fixed by bolts on the waterproof membrane. At the same time, the overflow port PVC waterproof membrane additional layer 12 completely covers the stainless steel sealing plate 2. Finally, only the stainless steel grate plate 32 is exposed outside, which not only increases the firmness of the overflow port structure, but also makes it more beautiful.
