Description
Technical Field
[0001] This utility model relates to the field of building waterproofing technology, and in particular to a device for isolating water accumulation at the doorway of a room. Background Technology
[0002] In building renovation, especially in the construction of rooms with water such as bathrooms and kitchens, a water retention test must be conducted after the waterproofing project is completed to verify the quality of the waterproofing layer. Traditional water retention test methods only fill the room with water, and the water level is relatively shallow (usually 20-30mm), which cannot effectively simulate the most unfavorable conditions in daily life where there is deep water on the floor (such as flooding caused by a clogged floor drain). More importantly, traditional methods cannot detect the risk of water seeping from the side of the room doorway, which is the weakest point of the waterproofing layer. If the doorway fails, it will cause the exterior floor and wall finishes of the bathroom to mold and rot, resulting in property damage.
[0003] Therefore, there is an urgent need for a specialized device that can effectively seal the doorway of a room, conduct high-level water storage tests, and thus comprehensively assess the reliability of the doorway's waterproofing. Summary of the Invention
[0004] This invention aims to address the shortcomings of existing technologies by providing a device for isolating water accumulation at the entrance of a room.
[0005] To achieve the above objectives, this utility model adopts the following technical solution: a device for isolating water accumulation at the doorway of a room, comprising a water-blocking plate installed at the doorway of the room, and further comprising:
[0006] The sealing assembly includes airbags respectively disposed on both sides of the baffle, a sealing strip disposed at the bottom of the baffle, and a waterproof membrane disposed on the inner side of the baffle, the waterproof membrane being configured to fold inward to the inside of the room and overlap and seal with the pre-constructed waterproof layers on the walls and floors of the room.
[0007] The threaded clamping assembly includes support frames respectively disposed at both ends of the outer side of the baffle plate. The top of the support frame is provided with an ear plate, and an adjusting rod is threadedly connected to the ear plate. The adjusting rod is rotatably connected to a pressure plate at one end facing the doorway side. A pair of connecting frames are provided on the outer side of the baffle plate between the support frames. A bidirectional threaded sleeve is rotatably connected through the connecting frame, and the two adjusting rods are respectively threaded to both ends of the bidirectional threaded sleeve. A handwheel for driving the rotation is provided in the middle of the outer wall of the bidirectional threaded sleeve.
[0008] The counterweight stabilizing component includes a counterweight groove disposed at the bottom of the support frame and a counterweight placed in the counterweight groove.
[0009] Specifically, the airbag is a strip-shaped inflatable bladder, connected to the air pump via an inflation tube.
[0010] Specifically, the sealing strip is a water-swellable waterproof strip or an elastic silicone strip.
[0011] In particular, the pressing surface of the pressure plate is provided with anti-slip texture or has an anti-slip rubber pad attached.
[0012] Specifically, the counterweight is one or more of the following: sandbags, metal counterweights, and cement blocks.
[0013] The beneficial effects of this utility model are:
[0014] This invention utilizes side airbags, a bottom sealing strip, and overlapping waterproof membrane to create a three-dimensional, multi-layered sealing system. When inflated, the airbags automatically fill gaps in the wall, the bottom sealing strip prevents water seepage, and the inner waterproof membrane forms a continuous whole with the existing waterproof layer, ensuring effective sealing even under high water pressure. The flexibility of the airbags allows the device to adapt to doorways of varying widths and slightly uneven wall surfaces. The entire device is detachable, reusable, and suitable for various doorway sizes, offering high versatility.
[0015] This utility model uses a bidirectional threaded sleeve to drive two adjusting rods to move synchronously, which can evenly and quickly tighten the device inside the doorway. It is easy to operate, has strong fixing force, effectively resists water pressure thrust, and prevents the device from shifting.
[0016] The counterweight stabilizing component of this invention provides downward pressure, further enhancing the device's anti-tipping and anti-slip capabilities. Together with the threaded tightening component, it forms a double safety net, ensuring the safety and stability of the testing process. Attached Figure Description

[0022] The following will describe in detail the embodiments of this utility model with reference to the accompanying drawings. Detailed Implementation
[0023] The present invention will be further described below with reference to the accompanying drawings and embodiments:
[0024] like Figures 1-4 As shown, a device for isolating water accumulation at the doorway of a room includes a water baffle 1 installed at the doorway of the room, as well as a sealing component, a threaded tightening component, and a counterweight stabilizing component.
[0025] The sealing assembly includes airbags 2 respectively disposed on both sides of the water baffle 1, a sealing strip disposed at the bottom of the water baffle 1, and a waterproof membrane 3 disposed on the inner side of the water baffle 1. The waterproof membrane 3 is configured to fold inward to the inside of the room and overlap and seal with the pre-constructed waterproof layer 4 of the walls and floor inside the room. The airbags 2 are strip-shaped inflatable airbags connected to an air pump through an inflation tube. The sealing strip is a water-swellable water-stop strip or an elastic silicone strip.
[0026] Specifically, the water-blocking plate 1 serves as the main structure, with a flexible waterproof membrane 3 fixed to its inner side (the side facing the room) by adhesive or mechanical strips. This waterproof membrane 3 can be folded inwards during installation, directly overlapping or pasted onto the completed waterproof layer 4 of the floor and walls, achieving a "seamless connection" between this device and the building's waterproofing system. This fundamentally eliminates the possibility of leakage at the joints, which is crucial for effective inspection. The airbag 2, after being inflated by an external air pump, expands and tightly presses against the side wall of the doorway, automatically compensating for gaps caused by uneven walls and forming a flexible seal. The bottom sealing strip expands slightly under the action of water or relies on its own elasticity to firmly seal the contact line with the ground, forming a second reliable physical sealing line together with the airbag 2.
[0027] The threaded clamping assembly includes support frames 5 respectively located at both ends of the outer side of the baffle plate 1. The top of the support frame 5 is provided with an ear plate 6, and an adjusting rod 7 is threadedly connected to the ear plate 6. The adjusting rod 7 is rotatably connected to a pressure plate 8 at one end facing the doorway. A pair of connecting frames 9 located between the support frames 5 are provided on the outer side of the baffle plate 1. A bidirectional threaded sleeve 10 is rotatably connected through the connecting frame 9, and the two adjusting rods 7 are threadedly connected to both ends of the bidirectional threaded sleeve 10 respectively. A handwheel 11 for driving the rotation is provided in the middle of the outer wall of the bidirectional threaded sleeve 10. The pressing surface of the pressure plate 6 is provided with anti-slip texture or has an anti-slip rubber pad attached.
[0028] Specifically, turning the handwheel 11 drives the bidirectional threaded sleeve 10 to rotate, and the two adjusting rods 7 extend outward or retract inward simultaneously, making the tightening or loosening process of the device highly efficient and labor-saving. The anti-slip texture or rubber pad on the contact surface of the pressure plate 8 further prevents slippage after tightening.
[0029] The counterweight stabilizing component includes a counterweight groove 12 located at the bottom of the support frame 5 and a counterweight 13 placed in the counterweight groove 12; the counterweight 13 is one or more of sandbags, metal counterweights, and cement blocks.
[0030] Specifically, the counterweight 10 (such as sandbags, metal counterweights, cement blocks, etc.) provides enormous downward pressure, significantly increasing the friction between the bottom of the device and the ground. This effectively resists the outward pushing force of water on the baffle plate 1 when water is injected indoors, complementing the lateral tightening force formed by the threaded tightening assembly, thus forming an extremely stable mechanical balance system and completely avoiding the risk of the device moving or overturning during the test.
[0031] When this utility model is in operation, place the device at the doorway so that the water-blocking plate 1 is located inside the doorway; fold the inner waterproof membrane 3 so that it overlaps with the waterproof layer 4 of the indoor floor and walls; turn the handwheel 11 to initially tighten the device inside the doorway through the adjusting rod 7 and the pressure plate 8; put sufficient counterweights 13 into the counterweight groove 12; use the air pump to inflate the airbags 2 on both sides until they are tightly pressed against the wall; finally, tighten the handwheel 11 again to ensure that the device is completely fixed; at this time, water can be injected into the room to conduct a high water level water storage test.
[0032] This invention utilizes an airbag 2 and a sealing strip to form a three-dimensional flexible seal, effectively adapting to different doorway sizes and uneven wall surfaces, ensuring a reliable seal. The combination of bidirectional threaded tightening and counterweight achieves rapid and secure fixing of the device, resisting high water pressure. Its inner waterproof membrane 3 can overlap with the room's original waterproof layer, achieving a seamless connection between the testing system and permanent waterproofing. The device is easy to operate, reusable, and can effectively conduct high-water-level water storage tests, thoroughly verifying the leak-proof performance at room doorways.
