Description

Technical Field

[0001] This invention belongs to the field of floor and roof construction technology, specifically, it relates to a floor surface covering and protection device. Background Technology

[0002] In cast-in-place floor slab roof structures, after the floor slab roof is poured and leveled, it needs to be covered for curing. The quality of curing has a significant impact on the waterproof performance, durability and structural stability of the outer structure.

[0003] In the early stages of the pouring and forming of floor slabs and roofs, during the surface water treatment phase, the traditional methods for treating surface water seepage are manual sweeping and wiping. This cleaning method is difficult to remove water from the surface of the floor slabs and roofs. The residual water will form a weak layer, which can easily lead to water seepage. In addition, the friction of brooms and other tools can easily scratch the uncured surface, which will damage the flatness of the floor slabs and roofs and affect the subsequent bonding of the covering layer.

[0004] During the initial setting and moisturizing stages after the concrete pouring of the roof slab, manual watering or the use of wet burlap sacks for moisturizing is generally employed. This not only results in a short moisturizing period but also easily contaminates the surface of the roof slab, thus affecting subsequent waterproofing construction. When using plastic film, it is easily blown away and becomes ineffective in strong winds. Watering sloping roof slabs can easily cause water shortages at higher levels and water accumulation at lower levels, exacerbating uneven humidity, increasing the risk of wall cracking, and affecting waterproofing performance and lifespan. Furthermore, when watering the roof slab for moisturizing, the impact of the water flow on the roof slab surface can also cause sand to form on the incompletely solidified roof slab surface.

[0005] In view of the above problems, a floor slab covering and protection device is proposed. Summary of the Invention

[0006] The technical problem to be solved by the present invention is to overcome the shortcomings of the prior art and provide a floor surface covering and protection device that can overcome or at least partially solve the above problems.

[0007] To solve the above-mentioned technical problems, the basic concept of the technical solution adopted by the present invention is as follows:

[0008] A floor slab covering and protection device includes a floor slab roof covering layer covering the floor slab roof. The floor slab roof covering layer includes a water-permeable and breathable membrane, a waterproof and breathable membrane, and a wetting layer. The water-permeable and breathable membrane and the waterproof and breathable membrane are respectively fixed to both sides of the wetting layer by hook and loop fasteners. The wetting layer includes rubber fixing strips and connecting water pipes. Multiple rubber fixing strips are arranged longitudinally, and multiple connecting water pipes are arranged transversely. The connecting water pipes pass through the rubber fixing strips and are fixed to the rubber fixing strips. The connecting water pipes and the rubber fixing strips are interlaced to form a grid frame. Water-absorbing blocks are provided in the grid frame. The connecting water pipes are provided with diversion holes for spraying water to the water-absorbing blocks, and the rubber fixing strips are provided with water guide grooves communicating with the inside of the connecting water pipes.

[0009] As a preferred embodiment of the present invention: when the waterproof and breathable membrane is fixed to the fully solidified floor slab and roof, the wetting layer circulates water to cool down and absorb the heat of the floor slab and roof, and the waterproof and breathable membrane isolates external pollutants from contact with the wetting layer and the floor slab and roof.

[0010] As a preferred embodiment of the present invention: when water seepage occurs on the floor slab and roof and when the floor slab and roof initially set, the permeable and breathable membrane is attached to the floor slab and roof; when water seepage occurs on the floor slab and roof, the floor slab and roof covering layer is unfolded and laid on the floor slab and roof and water is absorbed by the water-absorbing blocks after water removal; when the floor slab and roof initially set, water is filled into the floor slab and roof covering layer, and after the water-absorbing blocks are saturated, the water is released onto the floor slab and roof.

[0011] As a preferred embodiment of the present invention: it further includes a first support and a second support, the rolled floor and roof covering layer is disposed on the first support, and when the floor and roof covering layer is disposed on the first support, the water-permeable and air-permeable membrane is used to adhere to the floor and roof; the second support is provided with a water inlet component, and the connecting water pipe is connected to the water inlet component; the first support is provided with a first lifting component, and the first lifting component is provided with a water removal component.

[0012] In a preferred embodiment of the present invention: a first motor is fixedly mounted on the first bracket, and a take-up and release roller is rotatably mounted on the first bracket, the take-up and release roller being fixedly connected to the output end of the first motor.

[0013] In a preferred embodiment of the present invention: the water inlet assembly includes a second motor and a water pump respectively fixedly installed on both sides of the second bracket; a diverter pipe is rotatably installed on the second bracket; a limit plate is fixedly installed on the diverter pipe; the diverter pipe is fixedly connected to the output end of the second motor; a water inlet pipe is fixedly installed on the output end of the water pump; the water inlet pipe is connected to the diverter pipe through a rotating joint; both ends of the connecting water pipe are fixedly connected to the take-up and release rollers and the limit plate respectively; the limit plate is provided with a water passage hole connecting the connecting water pipe and the diverter pipe.

[0014] As a preferred embodiment of the present invention: the first lifting assembly includes a first guide rail and a first electric telescopic cylinder fixedly mounted on a first bracket, a first mounting plate is slidably mounted on the first guide rail, a first guide roller is rotatably mounted on the first mounting plate, and the first mounting plate is connected to the output end of the first electric telescopic cylinder.

[0015] As a preferred embodiment of the present invention, it further includes a second lifting assembly disposed on a second bracket. The second lifting assembly includes a second guide rail and a second electric telescopic cylinder fixedly mounted on the second bracket. A second mounting plate is slidably mounted on the second guide rail. A second guide roller is rotatably mounted on the second mounting plate. The second mounting plate is connected to the output end of the second electric telescopic cylinder. The floor and roof covering layer passes through the bottom of the first guide roller and the second guide roller.

[0016] As a preferred embodiment of the present invention: the dewatering assembly includes an upper pressure roller and a lower pressure roller rotatably mounted on a first mounting plate, and the floor and roof covering layer passes between the upper pressure roller and the lower pressure roller.

[0017] As a preferred embodiment of the present invention: a water receiving trough is fixedly installed at the bottom of the first mounting plate, the water receiving trough is located below the lower pressure roller, a cleaning scraper that is in contact with the bottom of the lower pressure roller is fixedly installed in the water receiving trough, and a drain pipe is fixedly installed at the bottom of the water receiving trough.

[0018] By adopting the above technical solution, the present invention has the following beneficial effects compared with the prior art:

[0019] This invention utilizes a grid frame formed by rubber fixing strips and connecting water pipes in the roof slab covering layer to support the water-absorbing blocks in close contact with the roof slab surface. The strong water absorption of the water-absorbing blocks allows for rapid and comprehensive absorption of permeable water, solving the problem of localized water accumulation that is difficult to remove during traditional manual cleaning. Simultaneously, the water-absorbing blocks can be reused after being squeezed by the upper and lower pressure rollers of the water removal component. Combined with the isolation effect of the permeable and breathable membrane, this avoids frictional damage between traditional cleaning tools and the uncured roof slab surface, protecting the flatness of the roof slab surface.

[0020] In the initial setting stage, this invention supplies water to the connecting water pipe through the water inlet component. The water enters the water-absorbing block through the diversion hole and is guided longitudinally through the water guide groove of the rubber fixing strip to ensure that the water-absorbing block is uniformly saturated. The saturated water-absorbing block slowly releases water to the surface of the floor and roof through the water-permeable and air-permeable membrane. This solves the problem of local water accumulation or leakage caused by the slope of the floor and roof in traditional manual watering. It also avoids the defects of wet burlap bags, such as short moisturizing period and easy contamination, as well as surface sanding caused by water flow impact. It achieves continuous and uniform moisturizing of the floor and roof surface and effectively prevents cracking.

[0021] In this invention, the permeable and breathable membrane and the waterproof and breathable membrane are fixed to both sides of the wetting layer by hook and loop fasteners, forming a double protection: the permeable and breathable membrane allows water vapor to permeate while isolating external dust and debris from contact with the floor and roof surface; the waterproof and breathable membrane blocks external rainwater and pollutants from entering while ensuring that internal water vapor can be discharged, avoiding the problem of the floor and roof surface being contaminated by mud and debris during traditional maintenance, ensuring the cleanliness of the base layer, and laying a good foundation for the subsequent waterproof coating construction.

[0022] In this invention, the first and second supports work together with retracting rollers and a motor to automatically retract and extend the roof covering layer; the first and second lifting components adjust the height of the protective layer through guide rollers to ensure that it fits tightly against the roof surface; the water removal component automatically squeezes the water-absorbing block to drain water, and collects water through a water collection trough and discharges it through a drain pipe, reducing manual intervention and solving the problem of low efficiency in traditional maintenance methods, which is especially suitable for the maintenance of large-area roofs.

[0023] The flexibility of the rubber fixing strip in this invention allows the grid frame to adapt to the irregular structure of the floor and roof surface; the design of the universal locking wheel and connecting plate facilitates the overall movement and fixation of the device, and the bracket spacing can be flexibly adjusted according to the length of the floor and roof; in response to strong wind environments, the weight of the protective layer is increased by filling the wetting layer with water, ensuring that it is tightly attached to the floor and roof surface, avoiding the problem of traditional plastic film being easily blown away, and adapting to complex construction environments such as sloping floor and roof surfaces and strong winds.

[0024] In this invention, the permeable and breathable membranes are detachable via hooks and loops, facilitating the replacement of damaged layers individually; the connecting water pipes are made of flexible hoses, adaptable to bending and stretching during the deployment and retraction process; the cleaning scraper of the water removal component can scrape off residual impurities on the surface of the lower pressure roller, ensuring stable water removal effect; the overall structural design takes into account both functionality and ease of maintenance, extending the service life of the device.

[0025] The specific embodiments of the present invention will now be described in further detail with reference to the accompanying drawings. Attached Figure Description

[0038] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments will be clearly and completely described below with reference to the accompanying drawings. The following embodiments are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0039] Example: Refer to Figures 1-10A floor slab surface covering and protection device includes a floor slab roof covering layer 4, which includes a water-permeable and breathable membrane 45, a waterproof and breathable membrane 44, and a wetting layer. The water-permeable and breathable membrane 45 and the waterproof and breathable membrane 44 are respectively fixedly installed on both sides of the wetting layer by hook and loop fasteners. The use of hook and loop fasteners for fixing is not only convenient for installation and easy for later maintenance and replacement, but also ensures the stability of the connection between the layers and ensures the overall performance of the protective layer.

[0040] The waterproof and breathable membrane 44 can be made of polytetrafluoroethylene (PTFE) membrane and fabric composite material. PTFE membrane has excellent waterproof performance. Its microporous structure can effectively block liquid water from passing through, while allowing gaseous water molecules to escape smoothly, achieving the dual functions of waterproof and breathable. When combined with fabric, it can also enhance its mechanical strength and durability, making it less prone to damage from external forces such as friction and stretching when it is attached and fixed to the floor slab and roof, and maintaining stable protective performance over a long period of time.

[0041] For the permeable and breathable membrane 45, polyester fiber needle-punched felt can be selected. This material has a rich pore structure and good air permeability, which can ensure that the water vapor absorbed and evaporated by the wetting layer can be discharged smoothly. At the same time, its water permeability is moderate. While blocking the entry of external solid pollutants, it will not hinder the permeation of water vapor. Moreover, polyester fiber needle-punched felt has good corrosion resistance and wear resistance, which can adapt to different external environments, extend the service life of the permeable and breathable membrane 45, and ensure its long-term effective isolation of external pollutants.

[0042] The wetting layer is the core component of this protective layer, which includes rubber fixing strips 42 and connecting water pipes 41. Multiple rubber fixing strips 42 are arranged longitudinally, and multiple connecting water pipes 41 are arranged transversely. The connecting water pipes 41 pass through the rubber fixing strips 42 and are fixedly connected to them. Through this arrangement and connection, the connecting water pipes 41 and the rubber fixing strips 42 interweave to form a stable grid frame. In this grid frame, water-absorbing blocks 43 are set. The water-absorbing blocks 43 can absorb and store moisture, providing a continuous wetting environment for the floor and roof structure, which is beneficial to the maintenance of the floor and roof.

[0043] In order to achieve the function of supplying water to the water-absorbing block 43, the connecting water pipe 41 is provided with a diversion hole 411. The diversion hole 411 can evenly spray the water in the connecting water pipe 41 onto the water-absorbing block 43, ensuring that the water-absorbing block 43 can fully absorb water. At the same time, the rubber fixing strip 42 is provided with a water guide groove 421 that communicates with the inside of the connecting water pipe 41. The water guide groove 421 can guide and divert excess water in the connecting water pipe 41, avoid water accumulation in a local area, and further improve the uniformity of water distribution.

[0044] Among them, the water-absorbing block 43 is preferably a sponge, which can store water and facilitate the replenishment of water to the sloping roof floor.

[0045] In summary, both the permeable and breathable membrane 45 and the waterproof and breathable membrane 44 can be used to contact the surface of the floor slab and roof. This protective layer can be applied to the surface of the floor slab and roof according to different usage environments.

[0046] When performing moisturizing and curing on three-dimensional concrete structures such as columns and walls, this protective layer can be wrapped around or attached to the surface of the building.

[0047] Reference Figure 8 When the floor and roof covering layer 4 is used for long-term protection of the floor and roof, the waterproof and breathable membrane 44 is attached to the floor and roof, and the floor and roof covering layer 4 is fixed to the floor and roof. During use, the wetting layer circulates water to cool down and absorb the heat of the floor and roof. The water-permeable and breathable membrane 45 isolates external pollutants from contact with the wetting layer and the floor and roof. In addition, the water vapor absorbed and evaporated by the wetting layer can also be discharged through the water-permeable and breathable membrane 45. In this embodiment, the water-absorbing block 43 can be a sponge block, but is not limited to a sponge block. The sponge block absorbs water and can not only be used to cool down the floor and roof, but also play a role in heat insulation when it is dry.

[0048] Reference Figures 1-10 It also includes a first support 1 and a second support 2. The rolled floor and roof covering layer 4 is set on the first support 1. When the floor and roof covering layer 4 is used on the first support 1, the water-permeable and breathable membrane 45 is used to adhere to the floor and roof. The second support 2 is provided with a water inlet component, and the connecting water pipe 41 is connected to the water inlet component. The first support 1 is provided with a first lifting component 5, and the first lifting component 5 is provided with a water removal component 6.

[0049] In use, the first bracket 1 and the second bracket 2 are placed at both ends of the roof slab, and then the roof slab covering layer 4 is released, so that the bottom of the roof slab covering layer 4 is in contact with the roof slab. Then, the device is controlled to implement different protective states according to different stages of the roof slab and the external environment, specifically:

[0050] When water seeps from the surface of the floor slab and roof, the moisture enters the wetting layer through the pores of the permeable and breathable membrane 45. The absorbent blocks 43 within the grid frame quickly absorb the moisture (the grid structure formed by the rubber fixing strips 42 and the connecting water pipes 41 ensures that the absorbent blocks 43 are in uniform contact with the surface of the floor slab and roof, avoiding localized leakage). At the same time, the waterproof and breathable membrane 44 blocks external dust and rainwater from entering, and the permeable and breathable membrane 45 isolates the floor slab and roof from external debris, providing double protection to prevent surface contamination. When the absorbent blocks 43 are full of seeping water, the floor slab and roof covering layer 4 passes through the water removal component 6 to remove the water. The rubber fixing strips 42 (made of flexible material) of the grid frame can be squeezed and deformed along with the absorbent blocks 43, squeezing out the water from the absorbent blocks 43. The water is drained through the permeable and breathable membrane 45, and then laid out again on the floor and roof to absorb water. Compared with the traditional method of removing (sweeping) water from floor and roof surfaces, this device uses water-absorbing blocks 43 in the floor and roof covering layer 4, supported by a grid frame formed by rubber fixing strips 42 and connecting water pipes 41, to tightly adhere to the surface of the floor and roof (including irregular structures). The porous structure of the water-absorbing blocks 43 (such as sponges) can quickly absorb water through capillary action. With the support of the grid frame, it ensures close contact with the surface of the floor and roof, avoiding local leakage. Subsequently, the water is squeezed by the upper pressure roller 61 and lower pressure roller 62 of the water removal component 6, and the rubber fixing strips 42 (made of flexible material) of the grid frame are removed. As the absorbent block 43 deforms, water can be completely drained through the permeable and breathable membrane 45, avoiding the problem of water accumulation in corners and grooves that is difficult to remove with traditional cleaning methods, resulting in more thorough removal without residue. Secondly, the absorbent block 43 is made of flexible material, and its contact with the floor and roof surface is gentle adsorption rather than friction. The squeezing and water removal process only targets the absorbent block 43 itself, unlike the friction between traditional cleaning tools (such as broom bristles or scrapers) and the surface, which can scratch the uncured paste. Combined with the isolation and protection of the permeable and breathable membrane 45, this protects the floor and roof surface from damage. Furthermore, after the absorbent block 43 is saturated with water, it can be quickly squeezed and removed by the water removal component 6, and then guided by the first guide. After being guided by roller 54 and the second guide roller 58, the surface can be laid out again without changing tools, greatly reducing the amount of manual operation. It is especially suitable for the high-frequency treatment needs during the continuous bleeding stage, while traditional cleaning requires repeated manual wiping and cleaning of tools, which is inefficient for large-area floor slabs and roofs. In addition, the water-absorbing block 43 removes bleeding water through a sealed adsorption method, and remains clean after being squeezed to remove water. With the protection of the waterproof and breathable membrane 44, no impurities will be introduced when it is reused, and the bleeding water is quickly discharged, which can reduce the dilution of water on the cement paste. This avoids the problem of tools carrying mud and sand and impurities to contaminate the surface or residual bleeding water forming a weak layer when cleaning is done in traditional ways, thus protecting the surface quality of the floor slabs and roofs.

[0051] During the initial condensation stage of the roof slab, the water inlet assembly delivers water into the roof slab covering layer 4. The water is then sprayed onto the absorbent blocks 43 through the diversion holes 411 of the connecting water pipe 41 and guided longitudinally through the water guide grooves 421 of the rubber fixing strip 42, ensuring the absorbent blocks 43 are uniformly saturated. The saturated absorbent blocks 43 release water onto the roof slab surface through the permeable and breathable membrane 45, replenishing moisture and preventing cracking. Compared to traditional humidification methods, this device, after delivering water into the roof slab covering layer 4 through the water inlet assembly, sprays water onto the absorbent blocks 43 through the diversion holes 411 of the connecting water pipe 41, while simultaneously utilizing the water guide grooves 421 of the rubber fixing strip 42. The longitudinal flow of moisture ensures that the absorbent blocks 43 are uniformly saturated, avoiding the problems of excessive or insufficient localized moisture and uneven humidification that are common in traditional humidification methods (such as manual watering or covering with wet burlap sacks). The saturated absorbent blocks 43 release water to the roof surface through the permeable and breathable membrane 45, continuously and stably replenishing moisture to the roof surface. This meets the humidity requirements during the initial condensation stage and prevents the roof surface from cracking due to lack of water. Compared to traditional methods where moisture evaporates quickly and requires frequent humidification, this method reduces the number of manual interventions. Furthermore, the entire process is completed within the roof covering layer 4, and the waterproof and breathable membrane 44... The device, together with the permeable and breathable membrane 45, provides double protection, preventing external dust and other debris from contaminating the roof surface during humidification. Traditional humidification methods expose the roof surface directly to the outside environment, posing a risk of contamination. Furthermore, traditional water-spraying humidification requires manual application of water to the roof surface, which can easily lead to localized water accumulation (affecting condensation) or missed areas (causing localized dryness and cracking) due to improper operation. The humidification is uneven, and the water evaporates quickly when exposed to air, requiring frequent repetition and resulting in high labor costs. In contrast, this device first absorbs and evenly saturates the water with the absorbent block 43 before allowing it to pass through the permeable membrane 45. Water is slowly released onto the floor and roof surface through the permeable and breathable membrane 45. During this process, the water comes into contact with the floor and roof surface through penetration rather than scouring. There is no mechanical impact force from the water flow, which will not damage the cement paste that has not yet hardened in the initial setting stage. This fundamentally avoids the risk of fine aggregates being exposed and sanding due to loss of bonding. The saturated water release of the absorbent block 43 is continuous and gentle. The permeable and breathable membrane 45 further buffers the speed and force of water release, ensuring that the water penetrates the floor and roof surface evenly and slowly. This satisfies the moisture retention requirements without causing a "scouring effect" due to excessive local moisture, thus protecting the integrity of the surface cement paste.

[0052] During the initial setting stage of the roof slab and when strong winds are blowing, water is injected into the roof slab covering layer 4, filling the water-absorbing blocks 43 and connecting water pipes 41. This increases the overall weight of the roof slab covering layer 4. Compared with traditional methods of protecting against strong winds (such as pressing down plastic film with heavy objects or manually reinforcing coverings), this device increases the overall weight of the roof slab covering layer 4 by injecting water into the connecting water pipes 41 and water-absorbing blocks 43. After being filled with water, the connecting water pipes 41 act as "load-bearing ribs" and work in conjunction with the water-absorbing blocks 43, combined with the grid frame, to ensure that the protective cover fits tightly against the roof slab surface, resulting in stronger wind resistance and stability. This avoids the displacement or being blown away by uneven wind forces that can easily occur with traditional methods of pressing down with heavy objects. At the same time, water injection can... Water is supplied to the absorbent block 43 through the diversion hole 411 of the water pipe 41. In conjunction with the waterproof and breathable membrane 44, it ensures the moisture retention needs of the floor and roof during the initial setting stage while resisting wind, avoiding the rapid evaporation and cracking of surface moisture caused by the covering being blown away in traditional protection methods. Moreover, no additional weight is required, and the water filling volume can be remotely controlled through the water inlet component, making operation convenient and reducing the labor intensity of traditional multi-person cooperation for fixing. In addition, the flexible material of the rubber fixing strip 42 allows the grid frame to deform appropriately with the force after water filling. Combined with the toughness of the waterproof and breathable membrane 44, it can buffer the impact of strong winds, reduce the friction between the protective cover and the floor and roof surface, extend the service life, and avoid the problem of traditional coverings being easily torn due to violent shaking.

[0053] Reference Figures 1-6 A first motor 31 is fixedly installed on the first support 1. A take-up and release roller 3 is rotatably installed on the first support 1. The take-up and release roller 3 is fixedly connected to the output end of the first motor 31. The water inlet assembly includes a second motor 85 and a water pump 83, which are respectively fixedly installed on both sides of the second support 2. A diversion pipe 8 is rotatably installed on the second support 2. A limit plate 81 is fixedly installed on the diversion pipe 8. The diversion pipe 8 is fixedly connected to the output end of the second motor 85. A water inlet pipe 84 is fixedly installed on the output end of the water pump 83. The water inlet pipe 84 is connected to the diversion pipe 8 through a rotating joint 82. The two ends of the connecting water pipe 41 are fixedly connected to the take-up and release roller 3 and the limit plate 81, respectively. The limit plate 81 is provided with a water passage hole that connects the connecting water pipe 41 and the diversion pipe 8.

[0054] In this embodiment, the extended portion of the connecting water pipe 41 is wound around the diversion pipe 8. When the floor and roof covering layer 4 is dewatered, the connecting water pipe 41 wound around the diversion pipe 8 is released, which makes it easier for the portion of the floor and roof covering layer 4 containing the water-absorbing block 43 to be rolled up, and then dewatered by the dewatering component 6.

[0055] Start the first motor 31, the first motor 31 drives the take-up and untake-down rollers 3 counterclockwise (e.g. Figure 1 As shown, the rotation releases the roof covering layer 4 wound on the take-up and release rollers 3, simultaneously starting the second motor 85. The second motor 85 drives the diversion pipe 8 to rotate counterclockwise (as shown). Figure 1As shown, when the diversion pipe 8 rotates, the limiting plate 81 rotates synchronously, winding the connecting water pipe 41 that is wrapped around the diversion pipe 8. During this process, the rotating joint 82 allows the diversion pipe 8 to remain fixed with the inlet pipe 84 when it rotates, preventing the water pipe from getting tangled and ensuring that the water flow channel is unobstructed when replenishing water later.

[0056] When it is necessary to remove water from the absorbent block 43, the first motor 31 drives the take-up and release rollers 3 clockwise (e.g., Figure 1 As shown, the system rotates to begin rewinding the floor slab and roof covering layer 4, simultaneously starting the second motor 85 to drive the distribution pipe 8 clockwise (as shown). Figure 1 As shown, the connecting water pipe 41 wound on the diversion pipe 8 is gradually released (matching the winding speed of the take-up and release roller 3) to avoid pulling or twisting the connecting water pipe 41, and to ensure that the floor and roof covering layer 4 (including the grid frame and water absorption block 43) enters the working area of ​​the water removal component 6 smoothly.

[0057] As the take-up and release rollers 3 continue to rewind, the portion of the floor and roof covering layer 4 containing the water-absorbing block 43 passes through the water removal component 6. The rubber fixing strip 42 (flexible material) of the grid frame is squeezed and deformed by the two rollers along with the water-absorbing block 43, and the water is discharged through the water-permeable and breathable membrane 45 to the water collection tank 7, thus completing the water removal.

[0058] The water passage hole on the limiting plate 81 ensures that the diversion pipe 8 and the connecting water pipe 41 are always connected (even during the opening and closing process), and reserves a channel for water replenishment in the subsequent initial condensation stage (the water pump 83 supplies water to the diversion pipe 8 through the inlet pipe 84 and the rotating joint 82).

[0059] In order to ensure that the water flow remains unobstructed even when the connecting water pipe 41 is tightened, the connecting water pipe 41 is preferably a rubber hose or a PVC reinforced hose. The rubber hose itself has good flexibility and elasticity, and can bend naturally with the curvature of the diversion pipe 8 when it is wound and tightened. Its pipe wall can adapt to deformation and is not easy to crack. The PVC reinforced hose (usually containing a fiber reinforcement layer) has higher tensile and compressive strength while maintaining flexibility. It is not easy to be flattened and blocked due to excessive tightening force when wound. The inner walls of both types of hoses are smooth and have strong sealing performance. As long as there is no excessive bending (forming a dead bend) or pipe wall damage during the winding state, the water flow channel can be kept unobstructed, meeting the connection requirements between the water passage hole of the limiting plate 81 and the connecting water pipe 41 (such as when the water pump 83 supplies water during the initial condensation stage, the water flow can smoothly reach the suction block 43 through the diversion pipe 8, the water passage hole, and the connecting water pipe 41).

[0060] When the initial condensation and moisturizing stage begins, the water pump 83 starts, and the water source is sent into the diversion pipe 8 through the inlet pipe 84 and the rotary joint 82. Then, it flows into the connecting water pipe 41 through the water passage of the limit plate 81, and finally supplies water to the water absorption block 43 through the diversion hole 411. At this time, the first motor 31 and the second motor 85 can be paused or finely adjusted to ensure that the floor and roof covering layer 4 adheres to the floor and roof surface and ensures that the moisture is released evenly.

[0061] In summary, the first motor 31 drives the take-up and release rollers 3 and the second motor 85 drives the diversion pipe 8 (with the limiting disc 81) to operate synchronously, ensuring precise matching of the take-up and release speeds of the floor and roof covering layer 4 and the connecting water pipe 41. During unfolding, the protective cover and the wound water pipe are released simultaneously; during rewinding and dewatering, the protective cover and the released water pipe are rewound simultaneously, preventing pulling and twisting and ensuring a smooth and efficient operation. The connecting water pipe 41 uses a rubber hose or a PVC reinforced hose, which, in conjunction with the water passage hole of the limiting disc 81 and the rotating joint 82, allows for stable water flow even during the winding process, thus adapting to both the take-up and release actions. It also provides a smooth channel for the water pump 83 to supply water during the initial condensation stage (through the inlet pipe 84 and the diversion pipe 8 to the water-absorbing block 43), achieving seamless connection of water intake, water removal, and water replenishment; the floor and roof covering layer 4 passes through the water removal component 6, and the rubber fixing strip 42 is squeezed and deformed by the water-absorbing block 43, and the water is discharged through the water-permeable and air-permeable membrane 45. During the initial condensation and water replenishment, water is supplied to the connecting water pipe 41 through the water passage, and the water-absorbing block 43 is evenly moistened through the diversion hole 411 and the water guide groove 421, and then water is released to the floor and roof through the water-permeable and air-permeable membrane 45, avoiding damage from traditional watering and reducing surface defects.

[0062] Reference Figures 3-6 The first lifting assembly 5 includes a first guide rail 51 and a first electric telescopic cylinder 52 fixedly mounted on the first bracket 1. A first mounting plate 53 is slidably mounted on the first guide rail 51, and a first guide roller 54 is rotatably mounted on the first mounting plate 53. The first mounting plate 53 is connected to the output end of the first electric telescopic cylinder 52. The assembly also includes a second lifting assembly mounted on the second bracket 2. The second lifting assembly includes a second guide rail 55 and a second electric telescopic cylinder 56 fixedly mounted on the second bracket 2. A second mounting plate 57 is slidably mounted on the second guide rail 55, and a second guide roller 58 is rotatably mounted on the second mounting plate 57. The second mounting plate 57 is connected to the output end of the second electric telescopic cylinder 56. The floor and roof covering layer 4 passes through the bottom of the first guide roller 54 and the second guide roller 58.

[0063] The first electric telescopic cylinder 52 drives the first mounting plate 53 to slide along the first guide rail 51, causing the first guide roller 54 to rise and fall. Simultaneously, the second electric telescopic cylinder 56 drives the second mounting plate 57 to slide along the second guide rail 55, causing the second guide roller 58 to rise and fall synchronously. Since the floor and roof covering layer 4 passes through the bottom of the first guide roller 54 and the second guide roller 58, this synchronous adjustment can precisely control the adhesion between the floor and roof covering layer 4 and the floor and roof surface—when protection or water absorption is needed, the guide rollers are lowered to ensure the floor and roof covering layer 4 adheres tightly to the surface; when temporary protection or water absorption is required, the guide rollers are lowered to ensure the floor and roof covering layer 4 adheres tightly to the surface; when temporary protection or water absorption is needed, the guide rollers are lowered to ensure the floor and roof covering layer 4 adheres tightly to the surface. When removing the protective cover (e.g., to check the surface condition of the floor or roof and adjust its position), the two guide rollers are raised to lift the floor or roof covering layer 4. The operation is flexible and the adjustment is precise. Compared with the traditional method of manually lifting or fixing the covering, this structure achieves automated and stable height adjustment through the cooperation of electric telescopic cylinders and guide rails. This avoids wrinkles or uneven fit of the protective cover caused by manual operation, while reducing the workload. It also ensures that the working state of the protective cover can be quickly switched at different curing stages of the floor or roof (e.g., bleeding, initial setting), thus improving the overall curing efficiency.

[0064] Reference Figure 7 The water removal assembly 6 includes an upper pressure roller 61 and a lower pressure roller 62 rotatably mounted on a first mounting plate 53. The floor and roof covering layer 4 passes between the upper pressure roller 61 and the lower pressure roller 62. A water receiving trough 7 is fixedly installed at the bottom of the first mounting plate 53. The water receiving trough 7 is located below the lower pressure roller 62. A cleaning scraper 72 that is in contact with the bottom of the lower pressure roller 62 is fixedly installed inside the water receiving trough 7. A drain pipe 71 is fixedly installed at the bottom of the water receiving trough 7.

[0065] The upper pressure roller 61 and lower pressure roller 62 exert stable pressure on the roof and floor covering layer 4 during the winding process, efficiently squeezing out the water from the absorbent block 43 and allowing it to seep out through the permeable membrane 45. This ensures that the absorbent block 43 is fully dehydrated, facilitating reuse to absorb water seepage from the roof and floor. Secondly, the water receiving trough 7 is precisely positioned below the lower pressure roller 62 to fully collect the squeezed-out water. The drain pipe 71 at the bottom allows for centralized water drainage, preventing water droplets from contaminating the roof and floor surface or the work environment, thus maintaining a clean construction environment. Furthermore, the clean water in the water receiving trough 7... The cleaning scraper 72 is attached to the bottom of the lower pressure roller 62, and can scrape off residual moisture and impurities on the surface as the roller rotates, preventing dirt accumulation from affecting the extrusion seal and ensuring a stable and long-lasting water removal effect. In addition, the water removal component 6 and the water receiving tank 7 rise and fall synchronously with the first mounting plate 53, and can always maintain the corresponding position with the floor and roof covering layer 4, ensuring that the water removal, collection and cleaning functions are not affected when the height of the protective cover is adjusted. This improves the overall coordination and work efficiency of the device and provides a reliable guarantee for the efficient treatment of seepage water during the maintenance of floor and roof.

[0066] Reference Figures 1-3The bottom of the first bracket 1 and the second bracket 2 are both fixedly installed with universal locking wheels 12. The first bracket 1 is provided with a first fixing hole 11 and the second bracket 2 is fixedly installed with a second fixing hole 21. It also includes a connecting plate 9. The bottom of the connecting plate 9 is fixedly installed with a limit post 91. The limit post 91 passes through the first fixing hole 11 and the second fixing hole 21 and is fixed by a nut.

[0067] The universal locking wheels 12 allow the first bracket 1 and the second bracket 2 to easily turn and move, facilitating the transfer of the device between different construction areas. When the device is retracted, the limiting post 91 of the connecting plate 9 passes through the first fixing hole 11 and the second fixing hole 21, and is then fixed with a nut, which can stably connect the two brackets into a whole, preventing the brackets from shaking or separating during movement. With the universal locking wheels 12, the device can be easily transported as a whole, adapting to scenarios that require frequent adjustments to the working position. By removing the limiting post 91 of the connecting plate 9, the fixing of the two brackets can be released, and the distance between the first bracket 1 and the second bracket 2 can be flexibly adjusted according to the length of the floor slab and roof, expanding the applicability of the device (such as adapting to different lengths of floor slabs, roofs, roads, etc.), taking into account both structural compactness and operational flexibility.

[0068] The first fixing hole 11 and the second fixing hole 21 can be fitted onto the fixing piles at the edge of the floor slab roof, which facilitates the retention or removal of water from the sloping floor slab roof.
