Description

Technical Field

[0001] The utility model belongs to the technical field of concrete maintenance, and relates to a concrete steep slope roof maintenance device. Background Art

[0002] The roof is the outermost structure of the building and plays a vital role in protecting the internal structure of the building. Compared with general concrete floors, the construction of the roof is more difficult and has higher quality requirements. First, in order to facilitate rainfall drainage, the steep slope concrete roof usually has a certain slope, which makes it difficult for the roof concrete maintenance spray device to work. Secondly, during the sprinkling maintenance process, due to the certain slope of the concrete roof after the surface is closed, the excess water on the concrete surface will flow down from the roof groove during the conventional spraying maintenance process, and the water resources cannot be fully utilized. Finally, as the outermost structure of the building, the concrete roof has higher requirements for crack control and waterproof performance. Therefore, after the concrete is poured, in order to ensure that the concrete roof has suitable hydration reaction conditions, reduce shrinkage, and reduce cracking, scientific and reasonable maintenance measures must be taken to ensure that the roof concrete can reach the design strength.

[0003] In the prior art, concrete roof maintenance is usually done by manual watering, that is, construction and maintenance personnel use handheld water guns to water the roof. This roof maintenance method has many safety hazards in actual operation, and the maintenance quality is difficult to guarantee, which is time-consuming and labor-intensive. The utility model patent with publication number CN 218438362 U discloses an automatic maintenance device for sloping roof concrete, which automatically maintains the maintenance time by manually setting the maintenance time. It relies on the engineering experience of the construction personnel and is easy to miss the best time to control the generation of early shrinkage cracks, resulting in poor concrete maintenance quality. In addition, the laying of the PVC hoses 7 on both sides is cumbersome and easily interferes with the unformed concrete roof. Summary of the invention

[0006] A number of temperature sensors and apparent hygrometers are arranged on the steep slope roof. The temperature sensors and apparent hygrometers are connected to the temperature and humidity controllers at the corresponding positions.

[0012] Furthermore, the scattering nozzle adopts a rocker-arm nozzle to achieve cyclic spraying maintenance.

[0015] Furthermore, the upper surface of the maintenance film includes a surface layer and a coating material from the outside to the inside, and both the surface layer and the coating material are water-permeable.

[0016] The beneficial effects of the utility model are:

DETAILED DESCRIPTION

[0028] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0029] like Figure 1-2 As shown, a maintenance device for a steep concrete roof includes a water pipe 3. The water pipe 3 is only arranged at the ridge 8 of the steep roof. The water pipe 3 is arranged along the length direction of the ridge 8. A plurality of scattering nozzles 2 are arranged on both sides of the water pipe 3. The water pipe 3 is assembled from a plurality of pipe sections to adapt to ridges 8 of different lengths, thereby improving flexibility and adaptability.

[0030] Each section of the water pipe 3 is connected via a flange 1 , and adjacent water pipes 3 are connected via a circle of connecting bolts 15 between the flanges 1 . Each section of the water pipe 3 is fixed to the roof ridge 8 via a corresponding pipe support 5 .

[0031] In some embodiments, Figure 6 As shown, the pipe support 5 includes a wooden support, a notch with a triangular cross section is provided at the bottom of the wooden support, and two bent spring sheets 53 (bent outward in the embodiment) are symmetrically installed at the notch, and the bending part of each spring sheet 53 is respectively connected to one end of a corresponding horizontally arranged adjusting screw 51, and the other end of the adjusting screw 51 passes through the side wall of the wooden support, and one end of the adjusting screw 51 passing through the side wall of the wooden support is connected to a nut 52, and by screwing the nut 52, the angle between the two spring sheets 53 is adjusted, and the adjustment range is 0-45 o , the water pipe 3 can be fixed on the ridge 8 of the concrete roof with different slopes without damaging the roof waterproof layer.

[0032] like Figure 3As shown, a branch water pipe 31 is provided inside the water pipe 3 in a direction perpendicular to the axis, and scattering nozzles 2 are installed at both ends of the branch water pipe 3. The scattering nozzle 2 is detachably connected to the water pipe 3 (through a threaded connection in the embodiment), which is convenient for repair and replacement of the scattering nozzle 2; a filter is provided at the nozzle of the scattering nozzle 2 to prevent clogging; the water pressure of the scattering nozzle 2 is controlled within a low water pressure range, and in order to avoid the water pressure from damaging the quality of the concrete roof in the initial setting state, in the embodiment, the maximum water pressure does not exceed 3kg / cm 2 .

[0033] In some embodiments, the scattering nozzle 2 adopts a fixed or rocker-arm nozzle, and the direction of the nozzle rocker arm can be parallel to the ridge line of the slope roof to achieve cyclic spraying maintenance. The scattering nozzle 2 can adopt a PY2H rocker-arm alloy nozzle.

[0034] One end of the water pipe 3 is connected to the water supply system through a flange 1. The water supply system includes a water pump and a water hose connected to the water pump. The water pump delivers the maintenance water to the water pipe 3 and then sprays it out through the scattering nozzle 2 on the water pipe 3 to achieve watering maintenance work.

[0035] A number of temperature sensors 7 and apparent hygrometers 16 are evenly arranged on the steep roof. The temperature sensors 7 and apparent hygrometers 16 are connected to the temperature and humidity controllers 4 at corresponding positions. The probes of the temperature sensor 7 are respectively installed on the inner and outer layers of the concrete to detect the temperature difference between the inner and outer layers of the concrete. When the temperature difference between the inner and outer layers of the concrete exceeds 35°C or the apparent humidity is lower than 60%, the temperature and humidity controller 4 controls the scattering nozzle 2 to turn on, and the scattering nozzle 2 starts watering for maintenance.

[0036] The temperature sensor 7 adopts a platinum thermal resistance temperature sensor with a temperature measurement range of -200~850℃. The apparent hygrometer 16 is HF3223, which has the advantages of good linearity, strong anti-interference ability, easy to match with digital circuits or single-chip microcomputers, and low price. The temperature and humidity controller 4 adopts the Ankerui WHD type, which displays the temperature and humidity values ​​in digital tube mode, and can set the system parameters by key programming, integrating measurement, display, control and communication functions.

[0037] The steep slope roof concrete to be maintained is located on the roof panel 12, the roof panel 12 is located on the concrete beam 10, the concrete beam 10 is located on the concrete column 11, the concrete column 11 is located inside, and the outside is the load-bearing wall 13.

[0038] In some embodiments, the water pipe 3 is made of PP-R material, which is light and convenient for workers to transport and install. Stainless steel pipes can also be used, which are highly firm and can effectively extend the service life of the maintenance device; as long as the use requirements are met.

[0039] The surface of the steep roof concrete is covered with a curing film 9. The curing film 9 uses the YHM-DP series 07P flat water-saving and moisturizing curing film, which uses a polymer absorption material as the core and a plastic film as the carrier. It can absorb water molecules 200 times its own weight; the curing film weighs 25g / m 2 The film is 1mm thick and contains high-efficiency moisturizing crystals. After absorbing water and swelling, the material becomes transparent crystals, turning liquid water into solid water, and then penetrates into the curing surface continuously through capillary action. At the same time, it continuously absorbs the evaporated water of the curing body during the heat of concrete hydration, ensuring that the relative humidity of the curing body surface is ≥90% during a curing period.

[0040] In some embodiments, Figure 5 As shown, the efficient moisturizing crystals inside the curing film 9 are distributed in mutually perpendicular warps 92 and wefts 91, and both the warps 92 and wefts 91 extend in a wave shape between the lower surface and the upper surface of the curing film 9. The curing film 9 absorbs the water sprayed by the scattering nozzle 2, and provides uniform curing water for the entire steep slope roof concrete through capillary action. During use, the warps 92 and wefts 91 extend in a wave shape between the lower surface and the upper surface of the curing film 9, absorbing the moisture in the vertical direction of the roof, so that the curing film 9 is close to the concrete roof, and sufficient curing water is provided for the concrete surface. The warps 92 and wefts 91 are mutually perpendicularly staggered, so that the curing water is evenly distributed on the steep slope roof, reducing the loss of curing water along the steep slope, and overcoming the adverse factors caused by the slope of the steep slope roof; the water in the curing film 9 penetrates into the concrete surface, and the scattering nozzle 2 provides water to the curing film 9 according to actual needs, ensuring that the roof concrete is always in the best curing state during the curing process.

[0041] The upper surface of the curing film 9 includes a surface layer 94 and a coating material 93 from the outside to the inside, and both the surface layer 94 and the coating material 93 have water permeability. The coating layer 93 is used to improve the weather resistance, corrosion resistance, self-cleaning and environmental protection of the curing film 9; the surface layer 94 is used to improve the surface flatness of the curing film 9 and reduce water evaporation. The specific material selection of the coating material 93 and the surface layer 94 is known in the art.

[0042] In order to realize the recycling of water resources, the concrete steep slope roof maintenance device of the utility model embodiment makes full use of the eaves external drainage structure 6 of the roof, such as Figure 4As shown, the external drainage structure 6 of the eaves includes a rainwater outlet 61, a rainwater gutter 62, and a rainwater pipe 63. The upper end of the rainwater outlet 61 is connected to the upper surface of the external eaves of the roof, the lower end of the rainwater outlet 61 is connected to the rainwater gutter 62, and the bottom of the rainwater gutter 62 is connected to the water tank through the rainwater pipe 63; the rainwater pipe 63 is stably connected to the outer wall through the pipe clamp 64 to prevent the rainwater pipe 63 from being offset and bent; the installation position of the pipe clamp 64 is generally at the upper and lower ends of the rainwater pipe 63. As the length of the rainwater pipe 63 increases, the pipe clamp 64 can also be added in the middle of the rainwater pipe 63.

[0043] When excess water flows down after roof maintenance, the water first enters the eaves, then is discharged into the water tank through the rainwater inlet 61, the rainwater bucket 62, and the rainwater pipe 63, and finally is transported to the concrete maintenance device through the water pump and the water delivery hose, forming a closed-loop system to save water resources. The roof eaves include a groove beam 14, the groove beam 14 is connected to the load-bearing wall 13, and the load-bearing wall 13 is fixedly connected to the roof panel 12.

[0044] The concrete roof maintenance process of the utility model embodiment is carried out according to the following steps:

[0045] S1: Inspection before maintenance; check whether the circuit parts of each test device are intact and usable, and prepare various devices and instruments required for concrete roof maintenance.

[0046] S2: Install the concrete curing device; first, adjust the bottom of the pipe support 5 to be consistent with the slope angle of the concrete roof by rotating the bolts, and fix the water pipe 3 at the ridge 8 through the pipe support 5; then install the scattering nozzle 2 at both ends of the branch pipe 31 inside the water pipe 3, and each section of the water pipe 3 is connected in series through the flanges 1 at both ends; the water pipe 3 only needs to be arranged at the ridge 8 of the steep roof, which is easy to install, and greatly reduces the interference with the concrete roof, thereby improving the quality of the concrete roof.

[0047] S3: transporting concrete curing water; starting the switch of the water pump (automatic booster pump) to transport the curing water to the water delivery pipe 3; conducting a closed water test on the concrete curing device, and after the closed water test is qualified, connecting the temperature and humidity controller 4 to the temperature sensor 7 and the apparent hygrometer 16 respectively; at this point, the installation of the concrete curing device is completed;

[0048] S4: Roof covering maintenance: after the initial setting of the concrete and before the final setting, the maintenance film 9 is manually laid;

[0049] S5: Recycling of curing water; the temperature and humidity controller 4 controls the opening or closing of the scattering nozzle 2 according to the temperature difference and humidity changes between the inner and outer layers of the concrete. After watering and curing, the curing water flows to the eaves of the roof under the combined action of gravity and the roof slope, and is then collected through the rainwater inlet 61, rainwater gutter 62, and rainwater pipe 63. The collected water is filtered or precipitated and then transported to the roof water tank again, forming a closed-loop system to make full use of water resources.

[0050] The utility model overcomes the problem of difficult maintenance of steep slope roof concrete through the mutual cooperation of water pipe 3, scattering nozzle 2 and maintenance film 9, improves the quality of concrete maintenance, reduces manual operation and ensures the safety of construction personnel. The temperature and humidity controller 4 controls the opening or closing of the scattering nozzle 2 according to the temperature difference and humidity of the inner and outer layers of the concrete, and performs timely maintenance, making the maintenance time more reasonable and improving the maintenance quality.
