Description

Technical Field

[0001] The present invention relates to the technical field of building waterproof maintenance construction, and in particular to a process for rapid compartmentalization, inspection, maintenance and treatment of steel-concrete roofs. Background Art

[0002] In modern architecture, steel-concrete roof structures are widely used due to their good load-bearing capacity and ease of construction. However, this structure is prone to leakage during long-term use, especially when exposed to severe weather and environmental factors.

[0003] To address leakage issues in reinforced concrete roofs, existing technical solutions primarily involve removing all structural layers down to the structural layer, then restoring the waterproofing layer and other structural layers. Specifically, maintenance personnel must first remove the roof's waterproofing layer, insulation layer, leveling layer, and other structural layers in sequence until the concrete structural layer is exposed. The structural layer is then inspected and repaired to ensure its flatness and strength meet requirements. Finally, the leveling layer, insulation layer, waterproofing layer, and other structural layers are re-applied to complete the roof repair.

[0004] In other words, existing steel-concrete roof leakage repair technology has obvious limitations. It fails to accurately locate the leakage area, resulting in a large repair scope, high repair costs, and long construction time, which brings a heavy burden to building maintenance and management. Summary of the Invention

[0005] The present invention provides a rapid compartmentalized inspection and repair and treatment process for steel-concrete roofs, which is used to solve the defects in the prior art that the water seepage area cannot be accurately located during the repair of steel-concrete roof leakage, resulting in an excessively large repair scope, excessively high repair costs, and excessively long construction period, which imposes a heavy burden on the maintenance and management of the building. The invention realizes that the leakage points of the steel-concrete structure roof can be quickly identified and targeted treatment can be carried out, thus saving a lot of construction time and repair costs.

[0006] The present invention provides a rapid compartmentalized inspection and repair process for a steel-concrete roof, comprising: According to the size of the roof, the entire roof is divided into n sub-compartment areas; A separation joint is opened between two adjacent compartment areas, and the separation joint is excavated from the protective layer to the structural layer; Set up formwork around the separation joint and pour polyurea grouting material into the separation joint until it is flush with the formwork to form a waterproof isolation belt; Conduct the first water storage test on each compartment to identify the compartments with leakage points; Repair and manage the sub-compartment areas where leakage points exist; Conduct a second water storage test on the repaired sub-compartment area and other sub-compartment areas to ensure that the roof waterproofing performance meets the requirements; The waterproof isolation strip on the roof that is higher than the protective layer is cut off to keep it flush with the original roof protective layer.

[0007] According to the present invention, a rapid compartmentalized inspection and repair process for a steel-concrete roof comprises the following steps when conducting a first water storage test on each compartmentalized area: Store water in each sub-compartment area and record the initial water level height H1 of each sub-compartment area; After m hours, observe and record the water storage height H2 of each sub-bin area; The difference between the recorded initial water level H1 of each compartment and the water storage height H2 after m hours is calculated, and the compartment where the leakage point is located is confirmed by the size of the difference.

[0008] According to a rapid compartment inspection and repair process for a steel-concrete roof provided by the present invention, when conducting a second water storage test on the compartment area after repair and other compartment areas, the process includes the following steps: Refill water into each sub-compartment area and record the initial water level height H1' of each sub-compartment area; After m hours, observe and record the water storage height H2' of each sub-bin area; The difference between the recorded initial water level height H1' of each sub-compartment area and the water storage height H2' after m hours is calculated; if there is no obvious difference between the calculated differences of each sub-compartment area, the repair process is successful; if there is a significant difference between the calculated differences of each sub-compartment area, the sub-compartment area with obvious difference will continue to be repaired until all repair processes are successful.

[0009] According to the invention, a rapid compartmentalized inspection and repair process for a steel-concrete roof further comprises the following steps after the polyurea grouting material protruding from the roof protective layer is removed: For the exposed polyurea waterproof coating in the maintenance area, continue to apply the exposed polyurea waterproof coating to the area 15cm outward to ensure that the exposed polyurea waterproof coating and the waterproof isolation belt are fully overlapped.

[0010] According to the invention, a rapid compartmentalized inspection and repair process for a steel-concrete roof further comprises the following steps before conducting the first water storage test: At the lowest point of each compartment area along the slope, a groove is chiseled from the protective layer to the structural layer; An exhaust pipe is buried in the groove.

[0011] According to a rapid compartmentalized inspection and repair process for a steel-concrete roof provided by the present invention, the exhaust pipe is an L-shaped exhaust pipe with a scale, and the exhaust pipe is between 100 mm and 150 mm higher than the protective layer.

[0012] According to a rapid compartmentalized inspection and repair process for a steel-concrete roof provided by the present invention, after the second water storage test is completed and the water is drained, an elbow is installed at the upper end of the exhaust pipe.

[0013] According to the steel-concrete roof rapid compartment inspection and repair and treatment process provided by the present invention, after confirming the compartment area where the leakage point exists, Drain the compartment area where there is a leakage point. After the protective layer is completely dry, apply polyurea waterproof coating to the surface layer of the compartment area where there is a leakage point, and ensure continuous overlap with the waterproof isolation tape at the separation joint.

[0014] According to the invention, a rapid compartmentalized inspection and repair process for a steel-concrete roof further comprises the following steps before the circumferential formwork is provided for the separation joint: Roughen the structural floor slab at the bottom of the separation joint; Clean the base layer and separation seams.

[0015] According to the invention, a rapid compartment inspection and repair process for a steel-concrete roof further comprises the following steps after the separation joints are excavated: Cut the waterproof membrane in the separation seam and reserve a joint for connection and fixation with the waterproof isolation belt.

[0016] The rapid compartmentalized inspection and repair process for steel-concrete roofs provided by this invention uses physical compartmentalization and polyurea grouting to achieve watertight isolation, followed by water storage testing to pinpoint the leak area. This reduces leak detection from a needle-in-a-haystack approach to localized detection, significantly improving both speed and accuracy. This targeted, localized repair avoids unnecessary complete renovations, significantly reducing repair time and costs. BRIEF DESCRIPTION OF THE DRAWINGS

[0029] The following combination Figures 1 to 5 , through specific embodiments and application scenarios, a steel-concrete roof rapid compartment inspection and maintenance management process provided by an embodiment of the present invention is described in detail.

[0030] In the embodiment of the present invention, Figure 1 and Figure 2 As shown, a rapid compartment inspection and repair and treatment process for a steel-concrete roof includes the following steps: according to the size of the roof 10, the roof 10 is divided into n compartment areas 20; a partition joint is opened between two adjacent compartment areas 20, and the partition joint is excavated from the protective layer 101 to the structural layer 103; a template is set up around the partition joint, and polyurea grouting material is poured into the partition joint until it is flush with the template to form a waterproof isolation belt 50; a first water storage test is carried out on each compartment area 20 to confirm the compartment area 20 with a leakage point; the compartment area 20 with the leakage point is repaired and treated; a second water storage test is carried out on the repaired compartment area 20 and other compartment areas 20 to ensure that the waterproof performance of the roof 10 meets the requirements; the waterproof isolation belt 50 of the roof 10 that is higher than the protective layer 101 is cut off to keep it flush with the protective layer 101 of the original roof 10.

[0031] According to the size of the roof 10, the roof 10 is divided into n sub-compartment areas 20 as a whole. This application provides clear partitions for subsequent investigation and maintenance work by dividing the roof 10 into multiple sub-compartment areas 20. This partitioning method allows maintenance personnel to check each sub-compartment area 20 one by one, rather than conducting a large-scale inspection of the entire roof 10, which greatly improves the efficiency and accuracy of the investigation. At the same time, the division of the sub-compartment area 20 also provides a clear range for subsequent local maintenance, avoiding unnecessary maintenance work, thereby saving maintenance time and cost. It should be noted that the specific value of n can be set according to the size of the different roofs 10, and is not specifically limited here. For example, the roof 10 is divided into 6m*6m sections by a spring line.

[0032] A partition joint is opened between two adjacent compartment areas 20, and the partition joint is excavated from the protective layer 101 to the structural layer 103. The partition joint is opened to completely isolate each compartment area 20 to ensure that each area does not interfere with each other in the subsequent water storage experiment. This isolation method enables maintenance personnel to accurately judge whether there is a leakage problem in each compartment area 20, avoiding misjudgment caused by unclear leakage points in traditional methods. In addition, the setting of the partition joint also provides space for the subsequent pouring of polyurea grouting material, ensuring that the polyurea grouting material can be tightly bonded to the structural layer 103 to form a reliable waterproof layer. The width of the partition joint can be set according to specific needs and is not specifically limited here. For example, the roof 10 is divided into 6m*6m sections with a line, and the steel mesh of the protective layer 101 of the roof 10 is cut off with a cutting machine in the area with a width of 2cm. Then, an electric drill or an impact drill is used to chisel out each structural layer to the structural layer 103 according to the cut area.

[0033] Formwork is installed circumferentially around the partition joints, and polyurea grouting is poured into the joints until it is flush with the formwork, forming a waterproof barrier strip 50. The purpose of the formwork installation is to ensure that the polyurea grouting forms a neat and uniform waterproof layer and to control the pouring height to ensure it is flush with the formwork. Polyurea grouting has high strength, high adhesion, and rapid curing properties, allowing it to bond tightly to the structural layer 103, forming a reliable waterproof layer. This waterproof layer not only prevents moisture from penetrating between the compartment areas 20 but also provides waterproof protection during subsequent maintenance, preventing further erosion of the structural layer 103.

[0034] An initial water filling test is conducted on each compartment 20 to identify the leaking compartment 20. This initial water filling test is designed to identify the leaking compartment 20. By filling each compartment 20 with water and recording the initial and final water filling levels after a certain period of time, maintenance personnel can compare the changes in water filling levels in each area and, based on the underlying leak information, pinpoint the leaking area. This method transforms leak detection from a needle-in-a-haystack approach to a narrowed-down area, significantly improving detection speed and accuracy and providing a clear target for subsequent maintenance work.

[0035] Repairs are performed on the leaking compartments 20. Once the leaking compartments 20 are identified, targeted repairs are performed. This localized repair approach avoids extensive demolition and repairs on the entire roof 10, reducing the scope and number of steps required, thus saving time and cost. Repairs only require treatment of the leaking area and its surrounding affected areas, minimizing the scope and time required, and rapidly restoring the roof 10's waterproofing performance.

[0036] A second water storage test is conducted on the repaired sub-compartment area 20 and other sub-compartment areas 20 to ensure that the roof 10 meets the required waterproofing performance. This second water storage test verifies the effectiveness of the repairs. By conducting another water storage test on the repaired sub-compartment area 20 and other sub-compartment areas 20, the waterproofing performance of each area is ensured to meet the required performance. If leakage is still detected during the second water storage test, additional repairs can be performed immediately without the need for a full re-inspection and repair. This step ensures the reliability and durability of the repair work and prevents the recurrence of leakage problems.

[0037] The waterproof barrier strip 50 of the roof 10 that protrudes above the protective layer 101 is removed to maintain it flush with the protective layer 101 of the original roof 10. After the repair is complete, the waterproof barrier strip 50 of the roof 10 that protrudes above the protective layer 101 is removed to restore the flatness and aesthetics of the roof 10. This step ensures that the normal use of the roof 10 after the repair is not affected, while also avoiding other problems that may arise from excessively high waterproof barrier strips 50, such as water accumulation and poor drainage. Furthermore, maintaining the flatness of the roof 10 also facilitates subsequent maintenance and management.

[0038] This application uses physical compartmentation and polyurea grouting to achieve watertight isolation, and then uses water storage testing to identify the leak area. This reduces leak detection from a needle-in-a-haystack approach to localized detection, greatly improving the speed and accuracy of detection. This targeted, localized repair avoids unnecessary full-scale renovations, directly and significantly saving repair time and costs.

[0039] In some embodiments, a rapid compartment inspection and repair process for a steel-concrete roof provided by the present invention includes the following steps when performing a first water storage test on each compartment area 20: Fill each sub-compartment area 20 with water and record the initial water level H1 of each sub-compartment area 20; After m hours, observe and record the water storage height H2 of each sub-bin area 20; The difference between the recorded initial water level H1 of each compartment area 20 and the water storage height H2 after m hours is calculated, and the compartment area 20 where the leakage point is located is confirmed by the size of the obtained difference.

[0040] It is understood that water is stored in each sub-compartment area 20 and the initial water level H1 of each sub-compartment area 20 is recorded. The same or sufficient amount of water is injected into each physically isolated sub-compartment area 20 to reach an initial, measurable water level (H1). Recording this initial water level in each sub-compartment area 20 is to establish a unified starting point for comparison. All subsequent water level changes will be measured based on this initial value.

[0041] After m hours, observe and record the water level H2 in each sub-compartment 20. Allow water for a sufficient period (m hours, which can be set based on experience or experimental objectives, such as simulating a specific rainfall duration or the minimum time required to observe leakage) to allow water to escape through potential leakage paths. After this period, measure and record the remaining water level (H2) in each sub-compartment 20. This measurement reflects the water loss in each individual area over the set time period. m is greater than or equal to 48.

[0042] The difference between the recorded initial water level H1 and the water level H2 after m hours in each sub-compartment 20 is calculated. The resulting difference identifies the sub-compartment 20 where the leak is located. Difference Calculation (H1-H2): By calculating the difference between the initial water level and the water level m hours later in each sub-compartment 20, the amount of water lost in that area over those m hours can be determined. This difference directly reflects whether there is water loss in that area.

[0043] In some embodiments, a rapid compartment inspection and repair process for a steel-concrete roof provided by the present invention includes the following steps when performing a second water storage test on the repaired compartment area 20 and other compartment areas 20: Refill water into each sub-compartment area 20 and record the initial water level H1' of each sub-compartment area 20; After m hours, observe and record the water storage height H2' of each sub-bin area 20; The difference between the recorded initial water level height H1' of each sub-compartment area 20 and the water storage height H2' after m hours is calculated; if there is no obvious difference between the calculated differences of each sub-compartment area 20, the repair process is successful; if there is a significant difference between the calculated differences of each sub-compartment area 20, the sub-compartment areas 20 with obvious differences will continue to be repaired until all repair processes are successful.

[0044] It is understood that water is refilled into each compartment 20 and the initial water level H1' is recorded in each compartment 20. After completing repairs to areas initially identified as leaking, it is necessary to confirm the effectiveness of these repairs and the overall waterproofing condition of the roof 10. Therefore, water is refilled into all compartments 20 (including previously repaired areas and those with no problems), and the initial water level H1' is recorded. This establishes a new benchmark for subsequent effectiveness evaluation.

[0045] After m hours, observe and record the water level H2' in each sub-compartment 20. Similarly, set an observation time (m hours) for the water. After this time, measure and record the remaining water level H2' in each sub-compartment 20 again. This is to assess whether water loss still occurs in the repaired sub-compartment 20 and whether the waterproof performance of all sub-compartment 20 as a whole has been improved. m is greater than or equal to 48.

[0046] Calculate the difference between the recorded initial water level H1' in each sub-compartment 20 and the water level H2' after m hours. Calculate the water level difference (H1' - H2') for each sub-compartment 20 during the second experiment. This difference reflects the water loss in that area over the m hours after the repair.

[0047] If the difference is not significantly different, the repair is successful. If a difference still exists, repairs are continued in the compartmented areas 20 with the difference until all repairs are successful. If the calculated differences in all compartmented areas 20 are very small, which is basically consistent with the ideal no-leakage state (only minimal evaporation loss), then the previous repair can be determined to be successful and the waterproof performance of the roof 10 has been restored.

[0048] If the difference in values for one or more compartmentalized areas 20 is significantly greater than the acceptable range, this indicates that despite initial repairs, these areas still have leakage or incomplete waterproofing. In this case, these compartmentalized areas 20 with remaining differences require further inspection and repair. This process (repair and re-water testing) is repeated until the difference in values for all compartmentalized areas 20 reaches the "no difference" standard, confirming that all leaks have been effectively addressed.

[0049] Reference Figure 3According to the invention, a rapid compartmentalized inspection and repair process for a steel-concrete roof includes the following steps after the polyurea grouting material on the roof 10 that is higher than the protective layer 101 is removed: For the exposed polyurea waterproof coating 70 in the maintenance area, continue to apply the exposed polyurea waterproof coating 70 to the area 15 cm outward to ensure that the exposed polyurea waterproof coating 70 and the waterproof isolation tape 50 are completely overlapped.

[0050] It is understood that after the polyurea grouting material protruding from the protective layer 101 of the roof 10 is removed, the exposed polyurea waterproof coating 70 is further applied to the repaired area, ensuring a complete overlap between the repaired area and the original waterproof layer. This not only improves the waterproof performance of the repaired area but also effectively prevents secondary leakage, ensuring the integrity and reliability of the waterproof layer of the entire roof 10.

[0051] Reference Figure 3 and Figure 4 According to the invention, a rapid compartmentalized inspection and repair process for a steel-concrete roof further includes the following steps before conducting the first water storage test: At the lowest point of each compartment area 20 along the slope direction, a groove 40 is chiseled from the protective layer 101 to the structural layer 103; An exhaust pipe 60 is embedded in the groove 40 .

[0052] It can be understood that by chiseling out a groove 40 at the lowest point along the slope of each compartment area 20 and burying an exhaust pipe 60 in the groove 40, not only an effective solution is provided for the drainage and exhaust of the roof 10, but also the construction quality and long-term stability of the waterproof layer are ensured.

[0053] Reference Figure 3 and Figure 4 According to a rapid compartment inspection and repair and management process for steel-concrete roofs provided by the present invention, the exhaust pipe 60 is an L-shaped exhaust pipe 60 with a scale, and the exhaust pipe 60 is between 100mm and 150mm higher than the protective layer.

[0054] It can be understood that the L-shaped structure ensures good steam exhaust and certain drainage functions, improving the accuracy of the water storage test; the scale makes the measurement of water level changes accurate, intuitive and quantitative; the height of 100-150mm ensures the feasibility of measurement, convenience of operation, and takes into account the cost.

[0055] Specifically, an L-shaped PVC exhaust pipe with a scale is buried, wherein the diameter of the exhaust pipe is DN50, the length of the lower end of the L-shape is 100mm, and the height of the upper end is 100-150mm higher than the protective layer. Waterproof mortar 100 or leak-proof king is used to fill and seal it tightly to facilitate subsequent pumping and drainage after water storage. A filter (non-woven fabric) is set at the lower inlet to avoid clogging of the pipe mouth.

[0056] In some embodiments, the walls of the exhaust pipe and the separation groove are embedded with polyurea grouting material to form a whole, and the rest of the groove is filled with waterproof mortar 100 to fix the exhaust pipe.

[0057] After the compartment area 20 with the leakage point is repaired and treated, a waterproof roll layer 90 is laid around the exhaust pipe to further improve the waterproof capability of the exhaust pipe around the exhaust pipe.

[0058] Reference Figure 4 and Figure 5 According to a rapid compartment inspection and maintenance process for a steel-concrete roof provided by the present invention, after the second water storage test is completed and the water is drained, an elbow 80 is installed at the upper end of the exhaust pipe 60.

[0059] It can be understood that by adding an elbow 80 at the upper end of the exhaust pipe 60, not only is the backflow of rainwater effectively prevented and the continuity of the exhaust function ensured, but the reliability, stability and aesthetics of the entire roof 10 waterproofing system are also improved.

[0060] Reference Figure 4 and Figure 5 According to the invention, a rapid compartmentalized inspection and repair process for steel-concrete roofs is provided. After confirming the compartmentalized area 20 where the leakage point exists, Drain the compartment area 20 where the leak is located. After the protective layer 101 has completely dried, apply polyurea waterproof coating 70 to the surface of the compartment area 20 where the leak is located, ensuring a continuous overlap with the waterproof isolation tape 50 at the separation joint. The exhaust pipe 60 is treated according to standard joint construction, with three coats applied in one layer, and the polyurea coating is applied to a height of no less than 100 mm.

[0061] It is understood that after accurately locating the leak point, waterproofing repair measures are implemented. By ensuring the base surface is dry, applying a targeted coating with a high-performance polyurea coating, and strictly ensuring continuous overlap with the surrounding waterproof layer, the confirmed leak problem can be fundamentally resolved, restoring the waterproof function of the compartment area 20, and ensuring the coordination and unity of the repaired area and the overall waterproofing system.

[0062] In some embodiments, a rapid compartment inspection and repair process for a steel-concrete roof provided by the present invention further includes the following steps before the circumferential formwork is provided for the separation joint: The structural floor slab at the bottom of the separation joint shall be roughened without damaging the structural layer 103 or exposing the reinforcement; Clean the base layer and separation seams.

[0063] It is understandable that the roughening process is to fundamentally solve the bonding strength problem between new and old materials (especially between them and the structural floor) to ensure a strong bond; the cleaning work is to create a clean working environment suitable for subsequent material construction to avoid quality defects caused by base surface problems.

[0064] In some embodiments, a rapid compartment inspection and repair process for a steel-concrete roof provided by the present invention further includes the following steps after excavating the separation joints: The waterproof membrane 102 in the separation seam is cut and a joint is reserved for connecting and fixing with the waterproof isolation tape 50 .

[0065] It will be appreciated that the reserved joint serves as a connection and fixation point with the waterproof barrier strip 50. During subsequent construction of the waterproof barrier strip 50, the joint can be tightly integrated with the waterproof barrier strip 50 to form a continuous, complete waterproof system. This effective connection avoids gaps or weak links between the new and old waterproof layers, prevents moisture from leaking into the roof 10 structure through the joint, and improves the waterproof performance of the roof 10.

[0066] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the various embodiments of the present invention.
