Abstract
Description
Technical Field
[0001] This invention relates to a roof waterproofing construction method, specifically a waterproofing construction method for sloping roof pergola beams in the renovation of old residential areas. Background Technology
[0002] Waterproofing the roofs of older residential communities, especially those with arched, reinforced concrete roofs (over 20 years old), remains a significant challenge. Due to years of neglect, the concrete has crumbled considerably, leading to severe leaks during heavy rains and greatly impacting residents' lives. Leaks are particularly severe at the base of the arched beams, significantly affecting residents' daily routines. Therefore, renovations and waterproofing of the roofs are necessary. However, current waterproofing methods involve laying waterproofing materials on the roof surface. Since arched beams are several arched reinforced concrete structures protruding from the roof, it's difficult to achieve a tight seal at the base of the arched beams, the roots of risers, and wall corners. Waterproofing the base of the arched beams, in particular, is a major challenge. Summary of the Invention
[0003] The purpose of this invention is to provide a method for waterproofing the sloping roof beams in the renovation of old residential areas, so as to solve the problems of low efficiency and poor sealing effect in the current waterproofing construction of roof beams.
[0004] The present invention is implemented as follows: a waterproofing construction method for sloping roof pergola beams in the renovation of old residential areas, comprising the following steps.
[0005] a. Lay waterproof membrane on the roof.
[0006] b. Lay square tubes between two adjacent pergola beams, with the square tubes fixed at intervals on the outer surface of the pergola beams.
[0007] c. Fix the base plate on the square tube. The base plate will cover the top of the flower stand beam to form a closed space. Open the air vent on the base plate near the top of the flower stand beam and open the water vent on the lower edge of the base plate. Place the vertical air vent pipe in the air vent and the horizontal water vent in the water vent.
[0008] d. Lay a waterproof membrane on the substrate, with the waterproof membrane on the substrate overlapping the waterproof membrane already laid on the roof at the lower edge of the substrate.
[0009] e. Lay colored tiles on the waterproof membrane on the substrate, and lay asphalt shingles on the waterproof membrane on the roof.
[0010] For the junction of the vent pipe and the substrate, firstly, sealant is used to seal the upper edge of the vent hole and the wall of the vent pipe. Then, a first layer of solid material is wrapped around the root of the junction between the vent pipe and the substrate. The first layer of solid material makes the transition between the vent pipe and the substrate smooth. A waterproof membrane is wrapped around the surface of the vent pipe and the first layer of solid material, and the waterproof membrane overlaps with the waterproof membrane on the substrate. After the colored tiles are laid, a second layer of solid material is wrapped around the waterproof membrane on the vent pipe. The second layer of solid material makes the transition between the vent pipe and the colored tiles smooth. A waterproof membrane is wrapped around the second layer of solid material, and the waterproof membrane overlaps with the colored tiles. The overlapping edge of the waterproof membrane and the colored tiles is sealed with sealant. At the same time, the edge of the waterproof membrane wrapped around the vent pipe is sealed with sealant.
[0011] A metal sleeve is fitted onto the vent pipe, and the upper part of the metal sleeve is compressed and tightened by clamps and fixed above the edge of the waterproof membrane. The upper end of the metal sleeve is sealed with sealant between the vent pipe wall and the vent pipe wall.
[0012] For the drain pipe, a waterproof membrane is laid on the extended part of the drain pipe, and the waterproof membrane on the drain pipe overlaps with the waterproof membrane on the roof and also overlaps with the waterproof membrane on the base plate.
[0013] At the junction of the base plate and the gable walls on both sides of the pergola beam, fill the corner with solid material to make the corner smooth. Lay the waterproof membrane and colored tiles upwards along the gable wall to a certain height. Place a pressure plate at the upper edge of the waterproof membrane and colored tiles, and place a metal plate on the outside of the pressure plate. Fix the metal plate and pressure strip to the gable wall surface with cement nails. Seal the upper edge of the waterproof membrane and colored tiles and the upper side of the pressure plate with sealant. Place a rubber gasket at the upper edge of the metal plate, and then fix the upper end of the metal plate to the gable wall surface.
[0014] At the junction of the substrate and the flue, fill the corner with solid material to make the corner smooth. Lay the waterproof membrane and colored tiles upward along the flue wall to the underside of the flue top plate. Use cement nails to fix the upper edges of the waterproof membrane and colored tiles to the flue wall. Then cover the flue top plate with solid material to seal the upper edges of the waterproof membrane and colored tiles.
[0015] The substrate is a cement fiberboard.
[0016] Expansion bolts are installed on the pergola beams, and the square tubes are welded and fixed to the expansion bolts.
[0017] The substrate is fixed to the square tube by screws.
[0018] This invention first lays a waterproof membrane on the roof, then lays a base plate on the pergola beams to form a sealed space for the pergola beams. Next, another waterproof membrane is laid on the base plate, overlapping the waterproof membrane on the ground. This design ensures that rainwater flows away along the waterproof membrane on the pergola beams, preventing it from accumulating on the roof below. Furthermore, the overlap between the waterproof membrane on the base plate and the roof membrane is simple and easy to install; at the junction of the sloping and horizontal surfaces, only the edges of the waterproof membrane need to be sealed, thus avoiding the need for extensive waterproofing work at the base of the pergola beams and reducing construction difficulty.
[0019] Ventilation and drainage pipes are installed in the sealed space formed by the pergola beams to ensure the dryness of the interior space, prevent dampness and mold, and improve the quality and service life of the waterproofing construction.
[0020] When using this invention for waterproofing truss beams on sloping roofs, it is highly efficient, simple to operate, and can effectively guarantee the waterproofing effect, making it suitable for waterproofing construction in the renovation of old residential areas.

[0026] like Figure 1 As shown, the present invention is a waterproofing construction method for the sloping roof 1 and pergola 2 of an old residential area renovation project, which includes the following steps.
[0027] First, waterproofing work is carried out on the roof surface 1 below the pergola beam 2, and waterproof membrane 3 is laid.
[0028] Waterproof membrane 3 is fully laid on the roof surface 1. At the base of the pergola beam 2, the waterproof membrane 3 is wrapped to a certain height and the edges of the waterproof membrane 3 are simply sealed.
[0029] After completing the waterproofing of roof 1, waterproofing of the pergola beams 2 is carried out. Square tubes 4 are overlapped between two adjacent pergola beams 2, and the square tubes 4 are fixed at intervals on the outer surface of the pergola beams 2, connecting all the pergola beams 2 into a whole through the square tubes 4.
[0030] After the square tube 4 is installed, the base plate 5 is laid on the square tube 4, and the base plate 5 fully covers the top of the flower stand beam 2, thereby forming a sealed space between the flower stand beam 2 and the space below it. Air vents are made on the base plate 5 near the top of the flower stand beam 2, and water vents are made on the lower edge of the base plate 5. A vertical air vent pipe 8 is placed in the air vent, and a horizontal water vent pipe 9 is placed in the water vent.
[0031] The upper end of the vent pipe 8 is bent so that the port faces downward, thereby preventing rainwater from entering. A small hole is opened on the lower part of the pipe body of the vent pipe 8 for the discharge of water vapor in the sealed space. The vent pipe 8 is fixed inside the vent hole.
[0032] The drain pipe 9 is fixed to the surface of the roof 1, and the middle of the roof 1 below the pergola beam 2 is slightly higher than the sides. When there is water in the enclosed space, the water will be discharged through the drain pipe 9 along the slope. A bird cover is installed at the outer end of the drain pipe 9 to prevent animals from entering the enclosed space through the drain pipe.
[0033] Then, a waterproof membrane 3 is laid on the substrate 5, and the waterproof membrane 3 of the substrate 5 overlaps the waterproof membrane 3 that has already been laid on the roof 1 at the lower edge of the substrate 5.
[0034] Finally, colored tiles 6 are laid on the waterproof membrane 3 on the substrate 5, and asphalt shingles 7 are laid on the waterproof membrane 3 on the roof 1, thus completing the waterproofing construction of the pergola beam 2.
[0035] Among them, such as Figure 2 As shown, at the junction of the vent pipe 8 and the substrate 5, sealant 10 is first used to seal the upper edge of the vent hole and the wall of the vent pipe 8. Then, a first layer of solid material 11 is wrapped around the root of the junction between the vent pipe 8 and the substrate 5. The first layer of solid material 11 makes the transition between the vent pipe 8 and the substrate 5 smooth. A waterproof membrane 3 is wrapped around the surface of the vent pipe 8 and the first layer of solid material 11. The waterproof membrane 3 overlaps with the waterproof membrane 3 on the substrate 5. After the colored tiles 6 are laid, a second layer of solid material 11 is wrapped around the waterproof membrane 3 on the vent pipe 8. The second layer of solid material 11 makes the transition between the vent pipe 8 and the colored tiles 6 smooth. A waterproof membrane 3 is wrapped around the second layer of solid material 11. The waterproof membrane 3 overlaps with the colored tiles 6, and the overlapping edge of the waterproof membrane 3 and the colored tiles 6 is sealed with sealant 10. At the same time, the edge of the waterproof membrane 3 wrapped around the vent pipe 8 is sealed with sealant 10.
[0036] The solid material 11 creates a smooth transition surface at the junction of the vent pipe 8 and the substrate 5. This prevents excessive bending angles of the waterproof membrane 3 during installation and avoids gaps or other sealing issues at the junction. Multiple layers of solid material 11, along with sealant 10, waterproof membrane 3, and colored tiles 6, ensure a tight seal at the junction of the vent pipe and the substrate 5.
[0037] To prevent the waterproof membrane 3 covering the exhaust pipe from falling off, a metal sleeve 12 is fitted onto the exhaust pipe 8. The upper part of the metal sleeve 12 is compressed and tightened by the clamp 13 and fixed above the edge of the waterproof membrane 3. The upper end of the metal sleeve 12 is sealed with sealant 10 between the upper end of the metal sleeve 12 and the wall of the exhaust pipe 8. The metal pipe can protect the waterproof membrane 3 and other components.
[0038] For the drain pipe, a waterproof membrane 3 is laid on the extended part of the drain pipe. The waterproof membrane 3 on the drain pipe overlaps with the waterproof membrane 3 on the roof 1 and also overlaps with the waterproof membrane 3 on the substrate 5.
[0039] like Figure 3 As shown, at the junction of the base plate 5 and the gable walls 14 on both sides of the pergola beam 2, a solid material 11 is filled at the corner of the base plate 5 and the gable wall 14 to make the corner smooth. The waterproof membrane 3 and the colored tile 6 are laid upwards along the wall surface of the gable wall 14 to a certain height. A pressure plate 15 is placed at the upper edge of the waterproof membrane 3 and the colored tile 6, and the upper edge of the waterproof membrane 3 and the colored tile 6 is pressed tightly against the wall surface of the gable wall 14 by the pressure plate 15. A metal plate 16 is placed on the outside of the pressure plate 15. The metal plate 16 is a pre-processed metal plate 16. The metal plate 16 and the pressure strip are fixed to the wall surface of the gable wall 14 at the same time by cement nails 17. The upper edge of the waterproof membrane 3 and the colored tile 6 and the upper side of the pressure plate 15 are sealed with sealant 10. A rubber gasket 18 is placed at the upper edge of the metal plate 16. Then, the upper end of the metal plate 16 is fixed to the wall surface of the gable wall 14. The upper end of the metal plate 16 is tightly fitted to the wall surface of the high wall 14 to prevent water from entering from that position, and then the water can flow downward along the metal plate 16.
[0040] like Figure 4 As shown, at the junction of the substrate 5 and the flue 19, a solid material 11 is filled at the corner of the substrate 5 and the flue 19 to make the corner smooth. The waterproof membrane 3 and the colored tile 6 are laid upwards along the wall of the flue 19 to the lower side of the top plate of the flue 19. Cement nails 17 are used to fix the upper edges of the waterproof membrane 3 and the colored tile 6 to the wall of the flue 19. Then, the solid material 11 is wrapped around the top plate of the flue 19 to seal the upper edges of the waterproof membrane 3 and the colored tile 6. In this way, rainwater will drip down along the top plate of the flue 19 and will not enter the upper edges of the waterproof membrane 3 and the colored tile 6, thus ensuring the waterproof effect.
[0041] Among them, the base plate 5 is a cement fiberboard, which is fixed to the square tube 4 with screws. For the top of the flower stand beam 2, the square tube 4 can be omitted and the cement fiberboard can be directly fixed to the top plate of the flower stand beam 2.
[0042] When installing square tube 4, first install expansion bolts on the pergola beam 2, and then weld and fix square tube 4 to the expansion bolts.
[0043] The solid material 11 involved in this invention is polymer cement mortar or adhesive mortar.
[0044] For locations such as lightning rod brackets or solar panel supports, seal the base with weather-resistant adhesive or wrap it with waterproof membrane and seal it tightly with sealant.
[0045] At the junction with the low gable wall, the waterproof membrane 3 and the colored tile 6 need to cover the top of the low gable wall, and a solid object 11 should be placed at the inside corner to make the corner smooth.
[0046] This invention first lays a waterproof membrane 3 on the roof surface 1 to waterproof the roof surface 1. Then, a base plate 5 is laid on the pergola beam 2 to form a partially sealed space on the pergola beam 2. The waterproof membrane 3 is then laid on the base plate 5, overlapping the waterproof membrane 3 on the ground. In this way, rainwater will flow away along the waterproof membrane 3 on the pergola beam 2 and will not accumulate on the roof surface 1 below the pergola beam 2. On the other hand, the overlap construction of the waterproof membrane 3 on the base plate 5 and the waterproof membrane 3 on the roof surface 1 is simple and easy to carry out. At the junction of the inclined surface and the horizontal surface, it is only necessary to ensure that the edges of the waterproof membrane 3 are sealed, thereby avoiding waterproofing construction at the base of many pergola beams 2 and reducing the construction difficulty.
[0047] Ventilation and drainage pipes are installed in the sealed space formed by the pergola beam 2 to ensure the dryness of the interior space, prevent dampness and mold, and improve the quality and service life of the waterproofing construction.
[0048] At the same time, key waterproofing construction was carried out on the exhaust pipe, drainage pipe, and high gable wall 14, thereby ensuring the waterproofing effect of the entire roof 1 with the pergola beam 2.
[0049] When using this invention to waterproof the truss beam 2 of a sloping roof 1, it is highly efficient, simple to operate, and can effectively guarantee the waterproofing effect. It is suitable for waterproofing construction in the renovation of old residential areas.
