Abstract
Description
A leak-proof device for rooms with water. Technical Field
[0001] This application relates to a leak-proof device for rooms with water, belonging to the field of building drainage technology. Background Technology
[0002] In the design of new buildings or renovations of existing buildings, conflicts often arise between rooms with water on upper floors and rooms with strict hygiene requirements on lower floors. According to Article 6.6.1 of the "Unified Standard for Design of Civil Buildings" GB50352-2019, due to the potential leakage risk of rooms with water on upper floors, rooms with strict hygiene requirements are not allowed to be located on the floor directly below them. This regulation severely restricts the location of rooms with water on upper floors. In some cases, to avoid rooms with strict hygiene requirements on lower floors, the function of the entire floor needs to be adjusted, resulting in an unreasonable floor plan design or wasted investment.
[0003] In current design examples, such as hotel room bathrooms being water-enabled rooms with a restaurant on the floor below, to avoid potential leaks, the bathroom floor is typically lowered for in-floor drainage. A reinforced concrete sealed cavity is then added at a certain distance directly below the lowered floor to act as a partition between the upper and lower floors. However, this approach also presents several problems:
[0004] First, because the added section is a sealed reinforced concrete cavity, leakage cannot be detected in a timely manner.
[0005] Secondly, a waterproof layer cannot be installed inside a reinforced concrete sealed cavity. If water accumulates for a long time, water seepage may still break through the reinforced concrete slab and enter the room below.
[0006] Third, the height of reinforced concrete cavities is generally not less than 500mm, which will result in insufficient clear height of the lower room, thus necessitating an increase in the overall floor height of the lower floor, resulting in a waste of investment. In addition, in the renovation of existing buildings, the floor height cannot be changed, and this practice will also result in insufficient clear height of the lower room, thus affecting normal use. Summary of the Invention
[0007] In view of this, this application provides a waterproofing device for a room with water, which effectively creates a waterproof barrier between the room with water and the lower floor, achieving multiple waterproofing and leak prevention for the room with water, and eliminating the potential danger of water leakage affecting the lower floor.
[0008] Specifically, this application is implemented through the following scheme:
[0009] A leak-proof device for a water-bearing room, located in the water-bearing room, includes a drop slab, a filling layer, and a waterproof cavity. The drop slab is set at a point where the structural floor slab of the water-bearing room drops by at least 250mm. Water pipes are installed within the space of the drop slab. A filling layer is set above the drop slab, and the top surface of the filling layer is flush with the bottom surface of the water-bearing room. A waterproof cavity is set below and around the drop slab to seal the area below and around the drop slab.
[0010] The aforementioned features of the water-bearing room enable multiple layers of waterproofing. The control of the drop size and the coordination between the drop slab and the filling layer ensure that the room height remains unchanged. The drop slab itself forms one layer of waterproofing, and the waterproof cavity below the drop slab forms a second layer of waterproofing, effectively preventing the impact of water leakage from the water-bearing room on the room below. The waterproof cavity also facilitates timely inspection and maintenance of the water pipes, eliminating the potential danger of water leakage to the room below.
[0011] Furthermore, as a preferred option:
[0012] The height of the waterproof cavity, i.e., the distance between the bottom of the waterproof cavity and the bottom surface of the drop plate, is 80~180mm, with 180mm being preferred.
[0013] The lowered slab has a waterproof layer on its side walls and inner bottom surface, located between the lowered slab and the filling layer. The lowered slab allows for the application of a waterproof layer in rooms with water, adding an extra layer of waterproofing.
[0014] The waterproof cavity includes several galvanized steel pipe joists, several (e.g., at least two) galvanized steel plate embedded parts, and a glass interlayer. The galvanized steel plate embedded parts are located below and around the lowered plate. The galvanized steel pipe joists are fixedly connected to the galvanized steel plate embedded parts, and the glass interlayer is installed between the galvanized steel pipe joists. More preferably, it also includes several fasteners, and the galvanized steel pipe joists are installed to the galvanized steel plate embedded parts through the fasteners. All gaps during installation can be sealed with building sealant to ensure the airtightness of the waterproof cavity.
[0015] The glass interlayer is provided with vent holes, at least two in total, each fitted with a silicone plug inserted from the outside of the glass interlayer. Normally, the vent holes are blocked with the silicone plugs. In case of leakage, the silicone plugs are removed, and the water inside the waterproof cavity is allowed to evaporate completely through natural evaporation or by blowing air into one of the vent holes to accelerate evaporation. The silicone plugs are then replaced. Epoxy resin adhesive can also be used to attach stainless steel rodent and mosquito netting to the inside of the glass interlayer at the locations corresponding to the vent holes.
[0016] In the glass interlayer, the inner side of the glass partition located below the lower plate is frosted. In the event of a leak, this area becomes transparent, allowing for visualization of the leak and timely detection and repair of the corresponding water pipe; once the leak is removed, this area returns to its opaque frosted state.
[0017] It also includes a suspended ceiling, with the ceiling and the bottom of the waterproof cavity being an integrated design. Even better:
[0018] The ceiling is equipped with an inspection hole.
[0019] The ceiling is equipped with mounting bases, and the waterproof cavity is fixedly connected to the ceiling through the mounting bases. The two together create a unique ceiling effect.
[0020] The beneficial effects of this application are:
[0021] (1) This application introduces a drop slab into the structural floor of the room with water. The first layer of waterproofing can be achieved by relying on the strong waterproof performance of the drop slab itself. The existence of the drop slab also facilitates the introduction of the waterproof layer in the building structure, which also forms a first layer of waterproofing. Even if a small amount of water seeps through the second layer of waterproofing of the drop slab and enters the waterproof cavity, the glass frosted surface at the bottom of the waterproof cavity will become transparent when wet. The small amount of water seepage in the waterproof cavity can be detected in the lower room in time. The connection method between the galvanized steel pipe keel and the glass interlayer can use the thickness of the galvanized steel pipe keel to frame the water seepage on the glass interlayer at different locations. The specific location of the water seepage pipe in the drop slab can be found more accurately, and the water seepage pipe in the drop slab can be repaired in time to avoid water seepage overflow. Thus, a reliable waterproof partition is provided between the room with water and the lower floor, completely eliminating the hidden danger of water seepage affecting the lower room. The room with water can be flexibly arranged on the upper floor of the room with strict hygiene requirements.
[0022] (2) The waterproof cavity consisting of glass interlayer and supporting structure is generally only 180mm high. The glass interlayer can be integrated with the ceiling design, occupying less floor height, which is conducive to saving costs, especially for the renovation of existing buildings.

[0033] Example 1
[0034] This application provides a leak-proof device for rooms with water. The embodiments of this application are described below with reference to the accompanying drawings.
[0035] Referring to Figures 1 and 2, which show schematic diagrams of the first structure of this embodiment.
[0036] Specifically, see Figure 1, which includes a drop plate 13, a filling layer 14, and a waterproof cavity 2.
[0037] The design elevation of the structural floor slab 11 of the water-bearing room 1 is lowered by no less than 250mm. Water pipes are installed in the space of the lowered slab 13 for same-floor drainage. It also includes a waterproof layer 15. There are two waterproof layers 15, which are installed on the inner side of the side wall and bottom surface of the lowered slab 13. The space of the lowered slab 13 above the waterproof layer is backfilled with lightweight aggregate concrete to the design elevation of the building ground, forming a filling layer 14.
[0038] The waterproof cavity 2 consists of a glass interlayer 3 and a support mechanism 4, which completely encloses and seals the bottom and sides of the drop plate 13.
[0039] The glass thickness of the glass interlayer 3 is not less than 5mm + 1.52PVB + 5mm, and each piece should not be larger than 1500mm × 2400mm. The inner surface of the glass interlayer 3 at the bottom of the waterproof cavity 2 is frosted. Referring to Figure 2, two circular vent holes 31 with a diameter of 50mm are arranged side by side on one side near the bottom, with a spacing of about 150mm. The inner side of the vent holes 31 is covered with a stainless steel rodent and mosquito net with epoxy resin adhesive, and the outer side is sealed with a circular silicone plug. The distance between the bottom surface of the glass interlayer 3 and the bottom surface of the drop plate 13 is about 180mm.
[0040] The support mechanism 4 includes an 80mm×80mm×5mm galvanized steel pipe keel 41 and a 150mm×4200mm×10mm galvanized steel plate embedded part 42. The galvanized steel plate embedded part 42 is installed on the bottom plate and side wall of the drop plate 13. The end of the galvanized steel pipe keel 41 is welded to the galvanized steel plate embedded part 42. The galvanized steel pipe keel 41 and the glass of the glass interlayer 3 are combined to enclose the bottom plate and side wall of the drop plate 13. All gaps are sealed with building sealant to form a closed waterproof cavity 2.
[0041] The vent 31 on the glass interlayer 3 on the side of the waterproof cavity 2 is normally plugged with silicone plugs. If the frosted glass surface at the bottom of the waterproof cavity 2 becomes transparent due to a small amount of water seepage, the leaking water pipe in the lower room can be detected and repaired in time. At the same time, the silicone plug can be pulled out to allow the small amount of water seepage in the waterproof cavity 2 to evaporate naturally or to blow air into one of the vents 31 to accelerate evaporation. After it is completely dry and the frosted glass surface returns to its frosted effect, the vent 31 is sealed with silicone plugs again.
[0042] Example 2
[0043] This application provides a leak-proof device for rooms with water. The embodiments of this application are described below with reference to the accompanying drawings.
[0044] Referring to Figures 3, 4, and 5, Figures 3 to 5 show schematic diagrams of the second construction of this embodiment.
[0045] Specifically, see Figure 3, which includes a drop plate 13, a filling layer 14, a waterproof cavity 2, and a suspended ceiling 12.
[0046] The design elevation of the structural floor slab 11 of the water-bearing room 1 is lowered by no less than 250mm. Water pipes are installed in the space of the lowered slab 13 for same-floor drainage. It also includes a waterproof layer 15. There are two waterproof layers 15, which are installed on the inner side of the side wall and bottom surface of the lowered slab 13. The space of the lowered slab 13 above the waterproof layer is backfilled with lightweight aggregate concrete to the design elevation of the building ground, forming a filling layer 14.
[0047] The waterproof cavity 2 consists of a glass interlayer 3 and a support mechanism 4, which completely encloses and seals the bottom and sides of the drop plate 13.
[0048] The glass thickness of the glass interlayer 3 is not less than 5mm + 1.52PVB + 5mm, and each piece should not be larger than 1500mm × 2400mm. The inner surface of the glass interlayer 3 at the bottom of the waterproof cavity 2 is frosted. Two circular vent holes 31 with a diameter of 50mm are arranged side by side on one side near the bottom, with a spacing of about 150mm. The inner side of the vent holes 31 is covered with a stainless steel rodent and mosquito net with epoxy resin adhesive, and the outer side is sealed with a circular silicone plug. The distance between the bottom surface of the glass interlayer 3 and the bottom surface of the drop plate 13 is about 180mm.
[0049] The support mechanism 4 includes an 80mm×80mm×5mm galvanized steel pipe keel 41 and a 150mm×4200mm×10mm galvanized steel plate embedded part 42. The galvanized steel plate embedded part 42 is installed on the bottom plate and side wall of the drop plate 13. The end of the galvanized steel pipe keel 41 is welded to the galvanized steel plate embedded part 42. The galvanized steel pipe keel 41 and the glass of the glass interlayer 3 are combined to enclose the bottom plate and side wall of the drop plate 13. All gaps are sealed with building sealant to form a closed waterproof cavity 2.
[0050] The ceiling 12 and the glass interlayer 3 with frosted bottom of the waterproof cavity 2 are integrated into one design, showcasing a unique effect.
[0051] Ventilation holes 31 are provided on the glass interlayer 3 on the side of the waterproof cavity 2. The ventilation holes 31 are normally plugged with silicone plugs. If the frosted glass surface at the bottom of the waterproof cavity 2 becomes transparent due to a small amount of water seepage, as shown in Figures 4 and 5, the leaking water pipe in the lower room can be detected and repaired in time. At the same time, the silicone plug can be pulled out to allow the small amount of water seepage in the waterproof cavity 2 to evaporate naturally or to blow air into one of the ventilation holes 31 to accelerate evaporation. After it is completely dry and the frosted glass surface returns to its frosted effect, the ventilation holes 31 are sealed with silicone plugs again.
[0052] The implementation steps of the anti-leakage device in the above embodiments are as follows:
[0053] Step 1: Lower the design elevation of the structural floor slab 11 of the water-bearing room 1 by no less than 250mm. Install two waterproof layers 15 on the side walls and the inner side of the bottom slab of the lowered slab 13. Place the water pipes of the water-bearing room 1 in the space of the lowered slab 13 and backfill with lightweight aggregate concrete to the design elevation of the building ground.
[0054] Step 2: Clean and level the outer side walls and bottom surface of the lowered slab 13 of the water-filled room 1, and measure its dimensions.
[0055] Step 3: Based on the measured dimensions, prefabricate 80mm×80mm×5mm galvanized steel pipe keel 41 and segmented glass interlayer 3. The thickness of glass interlayer 3 shall not be less than 5mm + 1.52PVB + 5mm, and each piece shall not exceed 1500mm×2400mm. The inner surface of the bottom glass interlayer shall be frosted. Two circular ventilation holes 31 with a diameter of 50mm shall be set side by side on one side near the top, with a spacing of about 150mm. The inner side shall be glued with epoxy resin to a stainless steel rodent and mosquito net, and the outer side shall be sealed with a circular silicone plug. The distance between the bottom surface of glass interlayer 3 and the bottom surface of drop plate 13 shall be about 180mm.
[0056] Step 4: Embed 150mm×200mm×10mm galvanized steel plate pre-embedded parts 42 on the bottom plate and side wall outside the drop plate 13, and reserve the height of the cavity according to the design.
[0057] Step 5: Install the prefabricated glass interlayer 3 onto the keel 41, and seal all gaps with building sealant to form a waterproof and sealed cavity, namely the waterproof cavity 2, and concentrate the ventilation holes 31 of different sections to facilitate later maintenance operations.
[0058] Step six: Integrate the frosted glass interlayer 3 at the bottom of the waterproof cavity 2 with the ceiling 12 to create a unique effect.
[0059] In this application, the ceiling 12 is made of ordinary paper-faced gypsum board. In practical applications, if the ceiling 12 is a grid, the grid spacing should not be less than 150mm so that the frosted glass at the bottom of the waterproof cavity 2 above the grid can be observed in time to see if it becomes transparent due to water seepage. If the paper-faced gypsum board ceiling seals the waterproof cavity 2 above it, it can be observed periodically through the inspection hole 6 set on one side of the ceiling 12 to detect any water seepage in time.
[0060] The above-described embodiments are merely illustrative of several feasible implementations of the present invention, and their descriptions are relatively specific and detailed. However, they should not be construed as limiting the scope of the present invention, nor are the embodiments intended to limit the scope of protection in the claims of the present invention. For those skilled in the art, various modifications and improvements can be made without departing from the concept of the present invention. All equivalent implementations or changes that do not depart from the present invention should be included in the technology of the present invention.
