Description

Technical Field

[0001] This utility model relates to the field of concrete roof maintenance, specifically to a maintenance system for sloping curved concrete roofs. Background Technology

[0002] Traditional curing methods for sloping, curved concrete roofs have the following problems:

[0003] 1) Due to gravity, the covering film is difficult to adhere tightly to the structural surface, and it is easy to slip and accumulate, resulting in incomplete coverage of the upper part of the roof. The concrete surface is directly exposed to the air, and the moisture evaporates quickly. Due to inadequate curing, the concrete loses water and shrinks, which poses a quality risk of roof structure leakage.

[0004] 2) In windy and windy environments, if a film covering is used, it requires frequent manual resetting, which is time-consuming, labor-intensive, inefficient, and may result in severe damage to the film.

[0005] 3) If manual watering is used for curing, the water will slide down quickly due to gravity and will not stay on the concrete surface. This requires frequent high-altitude operations, which is labor-intensive and time-consuming.

[0006] 4) When workers lay, re-cover, or water on sloping curved surfaces, there is a risk of slipping and falling. Safety belts, safety ropes, and other protective equipment are required. The construction is difficult and the safety risks are high.

[0007] Therefore, there is a need for a curing system for sloping concrete roofs that can improve the curing efficiency of sloping concrete roofs while reducing safety risks. Utility Model Content

[0008] In view of this, the purpose of this utility model is to overcome the defects in the prior art and provide a maintenance system for sloping curved concrete roofs that can improve the maintenance efficiency of sloping curved concrete roofs while reducing safety risks.

[0009] The present invention provides a curing system for sloping curved concrete roofs, comprising a spray pipe installed at the top of the sloping curved concrete roof and a return water pipe installed at the bottom of the sloping curved concrete roof.

[0010] The spray pipeline has several spray heads arranged along the width direction of the inclined arc concrete roof.

[0011] It also includes a water supply assembly, which includes a sedimentation tank and a water storage tank connected together; the water storage tank supplies water to the spray pipes through a pump assembly, and the return water pipes are connected to the sedimentation tank.

[0012] Furthermore, a filtration device is installed on the return water pipeline.

[0013] Furthermore, the area near the upper middle part of the sedimentation tank is connected to the water storage tank, and the highest water level of the water storage tank does not exceed the height of the connection point between the sedimentation tank and the water storage tank.

[0014] Furthermore, a water supply pipe is connected to the water storage tank, and the water supply pipe is controlled to be connected to or disconnected from the water storage tank.

[0015] Furthermore, the water supply pipe is automatically connected to or disconnected from the water storage tank via a float valve installed in the tank.

[0016] Furthermore, the inlet of the return water pipeline is equipped with an isolation plate grid, which is located on the front side of the filtration equipment.

[0017] Furthermore, it also includes a downpipe pre-embedded at a low position on the sloping concrete roof, the inlet of the return water pipe being connected to the bottom of the downpipe, the sloping concrete roof having a slope inclined towards the downpipe, and an isolation plate grid being installed at the pipe opening at the top of the downpipe.

[0018] Furthermore, the isolation plate grid includes a mesh base plate with drainage holes and a number of grid bars surrounding the mesh base plate, with gaps between adjacent grid bars.

[0019] Furthermore, the spray head is a rotary spray head.

[0020] Furthermore, the diameter of the downpipe exceeds the diameter of the return pipe, and the bottom of the downpipe is tapered, transitioning towards the diameter of the return pipe.

[0021] The beneficial effects of this utility model are as follows: The curing system for sloping curved concrete roofs disclosed in this utility model uses a pump that can be started and stopped at a time. During use, it can be started for a certain period of time according to the actual situation to achieve periodic water supply to the spray pipe. The spray head automatically sprays the sloping curved concrete roof periodically. The concrete roof is automatically cured by gravity water flow, which can improve the curing efficiency of sloping curved concrete roofs while reducing safety risks. It solves the problems of easy slippage of covering materials, low efficiency of manual curing, and high safety risks in traditional sloping curved concrete curing. It achieves efficient, energy-saving and safe curing operations, ensures a moist environment during the concrete setting stage, improves the impermeability of the roof structure, and saves water in the return water pipe. At the same time, this solution can also reduce the use and disposal of white pollution such as plastic film. Attached Figure Description

[0027] Figures 1-4 As shown in the figure, the curing system for sloping concrete roofs in this embodiment includes a spray pipe 1 installed at the top of the sloping concrete roof and a return water pipe 2 installed at the bottom of the sloping concrete roof. The spray pipe 1 has a plurality of spray heads 3 arranged along the width direction of the sloping concrete roof. It also includes a water supply assembly, which includes a sedimentation tank 4 and a water storage tank 5 connected together. The water storage tank 5 supplies water to the spray pipe 1 through a pump assembly 6, and the return water pipe 2 is connected to the sedimentation tank 4. The pump assembly 6 is selected from any existing timed start-stop pump. During use, it is started for a certain period of time according to the actual situation to achieve periodic water supply to the spray pipe 1. The spray head 3 then automatically sprays the sloping concrete roof periodically to ensure continuous concrete curing. The concrete roof is automatically cured by gravity water flow, and the water infiltrates naturally according to the roof slope, achieving a coverage rate of over 98%. This reduces safety risks while improving the curing efficiency of the sloping concrete roof. Furthermore, the continuous water film coverage prevents alternating wet and dry conditions on the concrete surface, improving crack resistance and seepage prevention performance by over 30%. The return water pipe 2 is used to receive the return water from the spray. It should be understood that a retaining wall 001 is provided around the top of the sloping concrete roof to prevent the loss of spray water, meet water conservation requirements, and reduce resource waste.

[0028] In this embodiment, the spray pipe 1 is arranged along the width of the sloping concrete roof at the top of the roof, and several spray heads 3 are provided along the width of the sloping concrete roof. In this solution, the spray heads 3 are rotary spray heads 3, preferably any water-driven rotary spray head 3 in the prior art, which has a self-driving rotation function, reducing the use of power equipment. In this solution, the rotary spray heads 3 are located inside the anti-sill 001, and the water spraying direction of the rotary spray heads 3 is at 60° with the horizontal direction; due to the existence of the anti-sill 001 When water sprays onto the inverted curb 001, it flows downwards to moisten the near end of the rotating sprinkler head 3 on the sloping curved concrete roof, improving the comprehensiveness of the curing of the sloping curved roof concrete. If the sloping curved roof does not have an inverted curb 001 design, this solution also includes a water baffle plate located behind the sprinkler pipe 1 and a protective plate 83 surrounding the entire perimeter of the sloping curved roof to meet the comprehensive curing function of this solution for concrete, which will not be elaborated here. The existing inverted curb 001 structure of the sloping roof in this solution avoids the need for additional components to be hung at high altitudes, ensuring construction safety.

[0029] In this embodiment, a filtration device 7 is installed on the return water pipeline 2. The filtration device 7 is preferably any of the existing multi-media filters, fiber filters, or screens, etc., to filter and adsorb suspended solids and small amounts of sand and gravel in the returned water to the sedimentation tank 4, thereby improving the quality of the returned water.

[0030] In this embodiment, the inlet of the return water pipe 2 is equipped with a baffle plate 8, which is located in front of the filtration device 7. The baffle plate 8 is used to initially screen out pollutants that fall near the return water pipe 2, generally including only wind-blown sand, leaves, and branches. The baffle plate 8 is used to improve the effectiveness of the return water pipe, ensure that the water flows smoothly back to the sedimentation tank 4 for reuse, improve resource utilization, and reduce resource waste.

[0031] In this embodiment, a downpipe 9 is pre-embedded at a low position on the sloping concrete roof. The downpipe 9 is located inside the bottom sill 001 of the sloping concrete roof. The inlet of the return water pipe 2 is connected to the bottom of the downpipe 9. The sloping concrete roof has a slope that is inclined towards the downpipe 9 to facilitate water collection. The isolation plate 8 is set at the pipe opening at the top of the downpipe 9 to provide protection and reduce impurities in the return water.

[0032] In this embodiment, the isolation grid 8 includes a mesh base plate 81 with drainage holes and several grid bars 82 surrounding the mesh base plate 81, with gaps between adjacent grid bars 82. The structure of the isolation grid 8 in this solution differs from the existing grate-type water filtration structure. Its periphery is provided with several comb-like grid bars 82, which increases the filtration area of ​​the drain outlet. The increased height of the grid bars 82 effectively prevents the mesh base plate 81 from being covered by debris, especially in windy and high-pressure environments, effectively preventing the drain outlet from being blocked and improving water return efficiency and reliability.

[0033] In this embodiment, a protective plate 83 is also provided on the top of several grid bars 82 to further ensure the protective function. The protective plate 83 can be fixed or removed on the top of the grid bars 82 according to the usage requirements. Generally, it is a fixed structure so that the overall isolation grid 8 has a box-like structure, which can effectively block debris such as branches and leaves. Even if it is blocked by a large area, water can still pass through the flow gap to ensure the smooth flow of return water. The multi-stage linkage filtration method of this solution can ensure the stability of return water quality, avoid nozzle clogging, and improve the stability of equipment operation.

[0034] In this embodiment, the diameter of the downpipe 9 exceeds the diameter of the return pipe, and the bottom of the downpipe 9 is tapered, transitioning towards the diameter of the return pipe; for example Figure 3 As shown, the top of the downpipe 9 is a cone shape with a large top and a small bottom. The middle part of the downpipe 9 is a pipe of equal diameter. The bottom of the downpipe 9 is also a cone shape with a large top and a small bottom. In this scheme, the bottom of the downpipe 9 continues to extend downward and bends repeatedly in the height direction to form an access end 91, which is used to connect with the return water pipe 2. This structure can intercept the larger substances in the return water step by step, generally including construction sand and gravel, improve the cleanliness of the return water, and prevent the bottom return water pipe 2 from being blocked.

[0035] In this embodiment, the area near the upper middle part of the sedimentation tank 4 is connected to the water storage tank 5. The highest water level of the water storage tank 5 does not exceed the height of the connection between the sedimentation tank 4 and the water storage tank 5, so that the water storage tank 5 is filled with clean water and no clean water is added to the sedimentation tank 4. The return water added to the sedimentation tank 4 in the water storage tank 5 is also contained, thus saving water resources and improving water resource utilization. In this solution, the water storage tank 5 is connected at the height where the sedimentation tank 4 is at 80% of its total volume. During maintenance, before cleaning the sedimentation tank 4, clean water is drawn out or used as cleaning water to clean the filter element, etc.

[0036] In this embodiment, a water supply pipe 10 is connected to the water storage tank 5. The water supply pipe 10 is controlled to open and close, connecting or disconnecting from the water storage tank 5. Preferably, the water supply pipe 10 is automatically controlled to open and close through a float valve 11 installed in the water storage tank 5. The float valve 11 can be any type of existing technology, which will not be described in detail here. In use, if the return water source is insufficient to replenish the water in the water storage tank 5, the float valve 11 will automatically start. In this solution, the float valve 11 is set to open when the water volume in the water storage tank 5 is less than 20% of its total volume, introducing water into the water supply pipe 10. The spray pipe 1 is connected to the bottom of the water storage tank 5.

[0037] In this embodiment, a control box 12 for controlling the pump assembly 6 is also included. The control box 12 is located close to the pump assembly 6 and relatively far from the water storage tank 5, improving safety during use. This solution can reduce the energy consumption of the water pump during idling through automatic water replenishment and timed spraying, achieving a certain energy-saving effect.

[0038] In this embodiment, both sedimentation tank 4 and water storage tank 5 are water collection buckets at the construction site. The sedimentation tank 4 is slightly larger in size. Since the curing cycle is generally 14 days, after the application of this solution, only mid-term cleaning of the downpipe 9, filter equipment 7, and sedimentation tank 4 is required, which greatly reduces the number of maintenance operations and the workload. Of course, the cleaning frequency is related to the severity of the construction site environment. If the construction site environment is good, unified cleaning can be carried out after completion, depending on the actual situation, which will not be elaborated here. The curing system using this solution can reduce manual climbing operations by 90%, with low safety risks and can save construction costs, making it highly economical. At the same time, this solution efficiently integrates and utilizes water resources, with a circulating water utilization rate of 85%, saving 60% of water compared to traditional sprinkler curing, which meets the requirements of green construction. This solution is applicable to the curing of concrete on various curved roofs with slopes of 15°~45° and curvature radii ≥20m, and can be extended to the curing of concrete surface layers of various irregular structures. The construction is simple and convenient, with low cost and high versatility.

[0039] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the spirit and scope of the technical solutions of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
