Technical Field

[0001] This invention relates to the field of tamping technology in building construction, specifically a method for precisely installing upright roof vent pipes. Background Technology

[0002] In central and northern China, design institutes generally design concrete roofs as "orthogonal" roofs. Based on the characteristics of orthogonal roofs, the "Roof Construction and Acceptance Specifications" require that "ventilation pipes" be installed on the roofs to avoid potential quality problems.

[0022] Please see Figures 1 to 10This invention provides a technical solution: a method for precisely installing a roof vent pipe, comprising the following specific steps: S1, determining the location of the vent pipe 1: using CAD to plan and lay out the roof, determining the location of the roof expansion joints and the vent pipe 1 exiting the roof; S2, constructing the insulation layer 2: constructing the roof insulation layer 2 according to the drawings; S3, constructing the building slope layer 3: using foamed concrete 10 for building slope construction; S4, reserving the vent channel 4: after the foamed concrete 10 has reached the required strength, measuring the vent channel 4 according to the layout drawing. S5. Pre-reserved positions: Extruded polystyrene strips 5 are bonded to the pre-reserved positions of venting channels 4 using polymer adhesive mortar; S6. Waterproof leveling layer 6 construction: When the strength of waterproof leveling layer 6 reaches 70%, the pre-reserved extruded polystyrene strips 5 are removed, forming longitudinal and transverse venting channels 4 on the roof; S7. Fixing venting pipe 1: After fixing the venting pipe 1 in position with the help of the workers using positioning template 7, a 100mm deep hole is drilled using water drilling equipment; S8. Waterproof protection construction: Construction of waterproof protection layer, curing, jointing, grouting, and cleaning of the roof; First, construct the roof insulation layer according to the drawings. Use foamed concrete 10 for building slope. After the foamed concrete 10 reaches the required strength, measure the reserved position of the venting channel 4 according to the layout drawing, and use polymer bonding mortar to attach the extruded polystyrene strip 5 to the reserved position of the venting channel 4. Then, construct the waterproof leveling layer 6. When the strength of the waterproof leveling layer 6 reaches 70%, remove the reserved extruded polystyrene strip 5. This forms the longitudinal and transverse venting channels 4 on the roof. After the waterproof leveling layer 6 dries, attach self-adhesive strips to the top of the venting channel 4. Use fixing tools to drill holes at the position of the venting pipe 1, and fix the venting pipe 1 according to the longitudinal and transverse control lines. Finally, construct the waterproof protective layer, and then perform curing, jointing, and grouting. Cleaning the roof is relatively convenient. Example

[0023] Based on Example 1, foamed concrete 10 is installed to facilitate the construction of the vent pipe 1. A concrete layer 8 is installed at the bottom of the insulation layer 2. The upper surface of the insulation layer 2 is a slope-forming layer 3, and the surface of the slope-forming layer 3 is foamed concrete 10. A waterproof leveling layer 6 is installed on the surface of the foamed concrete 10, and a second concrete layer 9 is installed on the surface of the waterproof leveling layer 6. After the foamed concrete 10 meets the strength requirements, the reserved position of the vent channel 4 is measured according to the layout drawing. The vent channel 4 is 40mm wide and the depth is the same as the thickness of the waterproof leveling layer 6, with a density of 30kg / m³. 3 The 40mm wide extruded polystyrene strip 5 is bonded to the reserved position of the venting channel 4 using polymer bonding mortar. After the waterproof leveling layer 6 is constructed, the extruded polystyrene strip 5 is removed to form the venting channel 4. The second cone surface of the second concrete layer 9 is provided with a sealing groove 11. A threaded pipe 12 is installed in the sealing groove 11, and a metal hoop 13 is screwed into the threaded pipe 12. The metal hoop 13 can fix the venting pipe 1, and then sealant is used to seal the venting pipe 1 and the metal hoop 13. When in use, the venting channel 4 is no longer placed using the traditional method of pre-reserving PVC pipes, but instead uses a pre-reserved extruded board strip 5 mold to achieve the purpose of setting the venting channel 4. The venting channel 4 is 40mm wide and the depth is the same as the thickness of the waterproof leveling layer 6, which reduces the cost to a certain extent. The metal hoop 13, together with the threaded pipe 12, also improves the installation and sealing of the venting pipe 1, making the effect better and the construction process simple. Example

[0024] Based on Embodiment 2, a positioning template 7 is provided to facilitate the installation of the exhaust pipe 1. The positioning template 7 has a square plate-like structure, and a guide ring 14 is provided on the surface of the positioning template 7. A threaded hole 15 is opened on the surface of the positioning template 7, and a positioning screw 16 is screwed into the threaded hole 15. A cone 17 is provided at one end of the positioning screw 16. The cone 17 can be moved down by rotating the positioning screw 16. The guide ring 14 is fixedly connected to the surface of the positioning template 7. A slot 18 is opened on the surface of the guide ring 14. The slot 18 has a "T"-shaped plate-like structure. Multiple sets of slots 18 are provided. The multiple sets of slots 18 are arranged in a regular circular pattern about the center point of the surface of the guide ring 14. A frame 19 is provided on the surface of the guide ring 14. A base 20 is inserted into the slot 18. A storage groove 21 is opened on the side of the base 20. A sliding hole is opened on the upper surface of the storage groove 21. An anti-slip sleeve 22 is provided on the inner side of the storage groove 21. A storage groove 21 is provided inside the storage groove 21. A limiting plate 23 is provided with a push plate 24 on its surface. The push plate 24 is inserted into the sliding hole. The limiting plate 23 can slide in the storage groove 21. One end of the limiting plate 23 can be inserted into the frame 19. A support plate 32 is provided on the side of the base 20. A rotating shaft 33 is inserted into the side of the support plate 32. A guide wheel 34 is sleeved on the surface of the rotating shaft 33. The guide wheel 34 can rotate around the rotating shaft 33. An auxiliary belt 25, a second upright plate 26 and a movable plate 27 are provided on the surface of the positioning template 7. The second upright plate 26 is fixedly connected to the surface of the positioning template 7. A traction rod 28 is provided on the side of the second upright plate 26. The auxiliary belt 25 passes under the traction rod 28. An installation plate 29 is provided at one end of the auxiliary belt 25. A bearing 30 is provided on the side of the installation plate 29. A movable screw 31 is fixedly connected to the inner ring surface of the bearing 30. A second threaded hole is opened on the side of the movable plate 27. The movable screw 31 is screwed into the second threaded hole. When positioning and installing the exhaust pipe 1, first place the positioning template 7 on a horizontal surface, with each side of the positioning template 7 perpendicular to the exhaust trough 4. Then, the worker's foot can be inserted into the auxiliary belt 25. By pressing down on the positioning template 7 with the worker's foot, and with the help of the cone 17 at one end of the positioning screw 16, the positioning template 7 is prevented from shifting during use. The movable screw 31 can be rotated to adjust the length of the auxiliary belt 25 in conjunction with the bearing 30, making it convenient for different workers' feet to be placed. Then, a 100mm diameter water drill is inserted into the guide ring 14 to drill to a depth of 1. A 00mm hole is drilled, and one end of the exhaust pipe 1 can be inserted into the hole for fixation. The guide ring 14, together with the guide wheel 34, can prevent the water drill from shifting during drilling, ensuring that the center of the exhaust pipe 1 and the center of the longitudinal and transverse exhaust channels 4 are aligned, and that the center of the exhaust pipe 1 is located at the center of the roof expansion joint. The rotation of the guide wheel 34 also prevents the water drill from rubbing against the side of the guide ring 14. When the guide wheel 34 needs to be replaced, the push plate 24 can be pulled to remove the limiting plate 23 from the frame 19, and the base 20 can be removed from the slot 18. The anti-slip sleeve 22 also prevents the limiting plate 23 from shifting.

[0025] Working principle: In actual use, the roof insulation layer is first constructed according to the drawings. Foamed concrete 10 is used for building slope. After the foamed concrete 10 meets the strength requirements, the reserved positions of the venting channels 4 are measured according to the layout drawing. Extruded polystyrene strips 5 are then pasted onto the reserved positions of the venting channels 4 using polymer adhesive mortar. The waterproof leveling layer 6 is then constructed. When the strength of the waterproof leveling layer 6 reaches 70%, the reserved extruded polystyrene strips 5 are removed, forming longitudinal and transverse venting channels 4 on the roof. After the waterproof leveling layer 6 dries, self-adhesive strips are pasted onto the upper part of the venting channels 4. Using a fixing tool, a hole is drilled at the location of exhaust pipe 1. Exhaust pipe 1 is fixed according to the longitudinal and transverse control lines. Finally, the waterproof protective layer is constructed, and the curing, jointing, and grouting are carried out. The cleaning of the roof is also more convenient. This avoids the problems that occur after the general on-site construction is completed, such as the exhaust riser not being on the same straight line in some places or the verticality of the exhaust riser not meeting the requirements, which affects the aesthetics. After the expansion joints are constructed on the roof surface, the center of the exhaust riser and the roof expansion joint are not on the same straight line. This is especially true after the roof plaza bricks are pasted, which affects the aesthetics and directly affects the project's achievement of excellence.
