Description

Technical Field

[0001] The invention relates to the technical field of expansion joint waterproofing, in particular to an anti-leakage water collection and drainage structure for building construction. Background Art

[0002] In building structures, expansion joints serve as necessary gaps between large concrete structures like floor slabs and walls to accommodate temperature fluctuations, differential settlement, and structural deformation. Their installation plays a crucial role in preventing structural cracking and extending the lifespan of buildings. To prevent rainwater, surface water, or other liquids from seeping into expansion joints, waterstops are typically installed. These waterstops are often made of rubber or PVC, offering a certain degree of elasticity and sealing properties, ensuring they remain waterproof even with minor building movement.

[0003] Deficiencies of existing technology:

[0004] During actual use, the waterstops at expansion joints may become damaged due to factors such as thermal expansion and contraction of the building, uneven foundation settlement, improper installation, or aging materials. Once the waterstop fails, rainwater may seep into the building structure through the gaps, causing structural safety issues such as wetting of the lower floor slab or wall, peeling, and even corrosion of steel bars. However, because the waterstop is embedded within the expansion joint, its actual working condition is difficult to directly observe. Especially after leakage occurs, it is impossible to accurately determine which section of the waterstop is damaged, making it impossible to carry out targeted local repairs, resulting in inefficient maintenance. Summary of the Invention

[0005] The purpose of the present invention is to provide a building anti-leakage water collection and drainage structure to solve the problems raised in the above background technology.

[0007] Through the above design, when the waterstop of the expansion joint leaks, rainwater can be discharged directly through the anti-leakage structure to prevent water from accumulating inside the structure and causing further damage; at the same time, since the water collection and drainage mechanism is composed of multiple units, maintenance personnel can accurately determine the leakage location of the waterstop through the water flow conditions of each water collection unit, and realize positioning maintenance, thereby significantly improving the targetedness and efficiency of maintenance, reducing maintenance costs, and extending the service life of the structure.

When the end surface of the retaining cylinder is in contact with the bottom of the annular groove, the through holes are concealed in the annular groove, and a retaining area is formed between the wall of the retaining cylinder and the second drainage portion;

[0017] A guide plate, fixed to the interception cylinder via a support rod, for guiding leaking rainwater to drain to the interception area;

[0018] A traction mechanism is provided on the retaining cylinder and / or the guide plate, and is used to guide the retaining cylinder to move along the axial direction of the annular groove.

[0019] Preferably, the traction mechanism is a magnetic block, and the magnetic block is arranged on the intercepting cylinder and / or the guide plate.

[0020] Through the cooperation of the above-mentioned water collector and interception mechanism, part of the water can be intercepted when leaking rainwater flows in, while allowing rainwater that exceeds the interception capacity to continue to be discharged smoothly, thereby providing a continuous and effective drainage channel to avoid structural water accumulation; at the same time, by intercepting the rainwater in the interception area, maintenance personnel can use the external magnetic block to control the upward movement of the interception tube to discharge the rainwater through the through hole, thereby observing the water collection or water discharge conditions below, and further confirming whether the water stop is damaged at this location, realizing secondary positioning of the leakage point, effectively reducing the scope of maintenance, and improving maintenance efficiency and accuracy.

Those skilled in the art will understand the specific meanings of the above terms in this patent based on the specific circumstances.

[0037] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of the technical features being referred to. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of such features. In the description of the present invention, "several" means two or more, unless otherwise specifically defined. Example

[0038] See also Figure 1-9As shown, the present invention provides a building anti-leakage water collection and drainage structure, which includes two floor slabs 1, an expansion joint 2 between the floor slabs 1, and a waterstop 3 installed on the expansion joint 2. The interior of the expansion joint 2 and the area located on the inner side of the waterstop 3 are provided with an anti-leakage structure 4 tightly connected thereto. The anti-leakage structure 4 is composed of several groups of water collection and drainage mechanisms 5, which are tightly connected to each other so that leaked rainwater flows into the water collection and drainage mechanisms 5.

[0039] Through the above design, when the waterstop 3 of the expansion joint 2 leaks, rainwater can be directly discharged through the anti-leakage structure 4, avoiding the accumulation of water inside the structure and causing further damage; at the same time, since the water collection and drainage mechanism 5 is composed of multiple units, maintenance personnel can accurately judge the leakage position of the waterstop 3 through the water flow conditions of each water collection unit, and realize positioning maintenance, thereby significantly improving the targetedness and efficiency of maintenance, reducing maintenance costs, and extending the service life of the structure.

[0040] The water collection and drainage mechanism 5 includes: a pair of pressure dischargers 501, several water collectors 502, a drainage pipe 505, an interception mechanism 506 and other components. The pressure discharger 501 is arranged in the expansion joint 2 and is tightly fitted with the inner side of the water stop 3. The water collectors 502 are arranged in sequence along the length direction of the pressure discharger 501, and the water collectors 502 are fixedly connected. Each water collector 502 is provided with a first drainage part 503 in the direction toward the water stop 3. The first drainage parts 503 between the water collectors 502 are tightly connected so that the leaked rainwater can flow into one of the water collectors 502. Each water collector 502 is provided with a drainage hole 504, and the drainage pipe 505 is connected to each drainage hole 504 for one-time confirmation of the leakage position of the water stop 3. The interception mechanism 506 is provided in each water collector 502 for secondary confirmation of the leakage position of the water stop 3.

[0041] In this embodiment, Figure 4 and Figure 7 As shown, the first drainage portion 503 has four end surfaces inclined downward, which are used to guide rainwater to flow into the collector 502; the first drainage portions 503 of two adjacent collectors 502 form a triangular outline structure at the connection point to prevent rainwater from being retained in the connection area, so that the leaked rainwater can smoothly flow into the collector 502, thereby improving drainage efficiency and subsequent maintenance and inspection.

[0042] A water collecting bottle 6 is provided at the drainage end of each drainage pipe 505 . An observation window 7 for observing the internal water level is provided on the water collecting bottle 6 . An external discharge port 8 is provided at the portion of the water collecting bottle 6 close to the water inlet.

[0043] This design makes it easy for operators to visually check whether there is water accumulation in each water collection bottle 6 after rainfall, so as to determine whether the water stop belt 3 in the area above the corresponding water collection and drainage mechanism 5 is leaking, and then quickly locate and preliminarily judge the leakage position, thereby improving inspection efficiency and maintenance targeting.

[0044] The interception mechanism 506 includes: an annular groove 5061, an interception tube 5063, a guide plate 5066, and a traction mechanism 9. The annular groove 5061 is provided in the water collector 502 and is located outside the drainage hole 504. A second drainage portion 5062 is provided between the annular groove 5061 and the drainage hole 504. The interception tube 5063 is movably provided in the annular groove 5061. A plurality of through holes 5064 are provided on the interception tube 5063. When the end surface of the interception tube 5063 is in contact with the annular groove 5061, the second drainage portion 5062 is provided. When the bottom of 061 is fitted, the through hole 5064 is hidden in the annular groove 5061. At this time, a retention area 5065 is formed between the wall of the retention cylinder 5063 and the second drainage part 5062. The guide plate 5066 is fixed to the retention cylinder 5063 through a support rod to guide the leaked rainwater to the retention area 5065. The traction mechanism 9 is provided on the retention cylinder 5063 and / or the guide plate 5066 to guide the retention cylinder 5063 to move along the axial direction of the annular groove 5061.

[0045] In this embodiment, the shape of the second drainage portion 5062 is preferably a conical funnel. This design is beneficial to improving the efficiency of rainwater drainage and preventing water flow from diffusing.

[0046] In this embodiment, the traction mechanism 9 is a magnetic block 901, which can be selectively arranged on the interception tube 5063 and / or the guide plate 5066, or on either component. As long as the interception tube 5063 can be effectively pulled and lifted, the through hole 5064 is exposed in the annular groove 5061, and the leaked rainwater is smoothly discharged from the interception area 5065, the purpose of controlling and observing the rainwater discharge can be achieved.

[0047] Through the cooperation of the above-mentioned water collector 502 and the interception mechanism 506, part of the water can be intercepted when leaking rainwater flows in, while allowing rainwater that exceeds the interception capacity to continue to be discharged smoothly, thereby providing a continuous and effective drainage channel to avoid structural water accumulation; at the same time, by intercepting rainwater in the interception area 5065, maintenance personnel can use the external magnetic block 901 to control the upward movement of the interception tube 5063 to allow rainwater to be discharged through the through hole 5064, thereby observing the water collection or water discharge conditions below, and further confirming whether the water stop belt 3 is damaged at this location, realizing secondary positioning of the leakage point, effectively reducing the maintenance scope, and improving maintenance efficiency and accuracy.

[0048] The end of the interception tube 5063 and the bottom of the annular groove 5061 are provided with matching protrusions 10 and recesses 11. This structural design helps to enhance the stability of the fit between the two, further realizing the interception barrier, improving the efficiency of intercepting leaking rainwater, and preventing water from flowing directly through the contact interface, thereby improving the reliability of the interception effect.

[0049] Markings 12 are provided on the floor 1, corresponding to the locations of the drain pipes 505 and indicating the specific locations of the associated drainage channels. This design facilitates the operator to quickly locate the corresponding drainage path during leak detection, enabling precise calibration of the leak location on the waterstop 3 and improving detection efficiency and accuracy.

[0050] The connection parts between adjacent water collectors 502 are arranged in a straight line. This design helps to standardize the structure, facilitate modular design and aligned installation, reduce connection complexity, and improve installation efficiency and construction convenience.

[0051] The working principle of the present invention is as follows:

[0052] In the anti-seepage water collection and drainage structure for buildings of this embodiment, when a section of the waterstop 3 leaks, the leaked rainwater first falls into the corresponding water collector 502 and, guided by the first drainage portion 503, flows into the retention area 5065 within the water collector 502. The rainwater gradually accumulates in the retention area 5065. When the water level exceeds the height of the retention tube 5063, the excess rainwater bypasses the retention tube 5063 and, guided by the second drainage portion 5062, flows through the drain pipe 505 into the water collection bottle 6, ultimately exiting the system through the external outlet 8.

[0053] On the other hand, by observing whether there is rainwater in the water collecting bottle 6, it can be preliminarily determined whether leakage occurs at the corresponding position above the water stop 3, thereby completing the primary positioning of the leakage point.

[0054] During secondary positioning, the operator can use another magnetic object to perform a magnetic attraction operation above the waterstop 3, causing the interception tube 5063 to move upward under the action of the magnetic force, exposing the through hole 5064 outside the annular groove 5061. If there is water accumulation in the interception area 5065, the rainwater will be further discharged through the through hole 5064 and into the water collection bottle 6. The personnel below can use this drainage situation to further confirm whether the leak is occurring at that specific location, thus achieving secondary confirmation of the leak location and carrying out precise and efficient local repair work, significantly improving maintenance efficiency and repair accuracy.

[0055] The above shows and describes the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The above embodiments and descriptions are merely preferred examples of the present invention and are not intended to limit the present invention. Various changes and improvements may be made to the present invention without departing from the spirit and scope of the present invention. Such changes and improvements fall within the scope of the present invention. The scope of protection claimed in the present invention is defined by the appended claims and their equivalents.
