Description

Technical Field

[0001] The present application belongs to the technical field of building waterproofing, and in particular relates to a waterproof structure for an exterior wall structure. Background Art

[0002] Waterproofing of building exterior walls is an important part of ensuring building durability and indoor environmental comfort, but there are still many deficiencies in actual projects. The following is an analysis of the current status and main problems: Materials are becoming more diverse. Commonly used materials include polymer cement-based waterproof coatings, acrylic coatings, polyurethane waterproofing layers, waterproof mortars, and sealants. Newer materials (such as penetrating crystalline waterproofing agents and silane-modified materials) are also becoming increasingly popular. The combination of external insulation systems (such as EPS / XPS boards) and waterproofing layers has become mainstream.

[0003] The expansion of application, with higher waterproofing requirements for high-rise buildings, curtain wall systems, and prefabricated buildings, has driven the evolution of waterproofing technology. Advances in detection methods have led to the gradual application of technologies such as infrared thermal imaging, water spray testing, and airtightness testing in leak diagnosis.

[0004] The main deficiencies were inadequate joint treatment: poorly designed details around window frames, expansion joints, and wall-penetrating pipes, making them prone to leaks. Material mismatch with the base layer: failure to consider the characteristics of the base layer (e.g., masonry, concrete, insulation), leading to bond failure. Neglected drainage design: the exterior walls lacked drainage structures (e.g., drip lines and gutters), allowing accumulated water to seep into the walls.

[0005] Material issues and insufficient durability: Some materials have poor resistance to UV rays and temperature fluctuations, making them susceptible to aging and cracking. Environmental friendliness needs improvement: Solvent-based paints are prone to VOC pollution, and green materials are expensive. Poor compatibility: The waterproof layer and decorative layers (such as tiles and paint) do not adhere firmly, resulting in hollowing and peeling.

[0006] Inconsistent construction quality and improper base layer preparation: cracks and holes in the wall are not repaired before waterproofing is applied directly. Irregular workmanship: uneven coating thickness, loose joints, and inadequate maintenance. Cutting corners: reducing the number of waterproofing layers or using inferior materials.

[0007] Lack of maintenance: Lack of regular inspection and maintenance after completion. Small cracks or local damage are not repaired promptly, leading to leakage. Special construction challenges: Prefabricated buildings: Leakage caused by aging or deformation of sealants at the joints of prefabricated components. Curtain wall systems: Open curtain walls have poor drainage, while closed curtain walls lack airtightness. Old buildings: Ineffective waterproofing makes retrofitting difficult.

[0008] For example, the existing patented technology, "A Waterproof Upturn Structure for Integrated Insulation and Structural Building Exterior Walls" (CN202411870640.8), relates to the field of construction engineering technology. This integrated insulation and structural building exterior wall waterproof upturn structure includes a waterproof membrane, which is applied to the exterior side of the underground wall structure and the exterior side of the above-ground wall structure below the overhang. The membrane is applied to the bottom, exterior side, and top surfaces of the overhang, with the membrane end structure located on the top surface of the overhang. A first insulation layer is disposed between the waterproof membrane and the insulation composite panel and is applied to the exterior side of the overhang. A second insulation layer is applied to the exterior side of the waterproof membrane between the overhang and the underground wall structure. The installation height of the waterproof membrane can be adjusted by adjusting the overhang's position on the above-ground wall structure. Furthermore, the waterproof membrane can be directly connected to the wall structure, thereby improving the adhesion between the waterproof layer and the wall structure in the integrated insulation and structural building exterior wall. However, the corresponding waterproof membrane is still a monolithic structure, which is not conducive to future repair and maintenance. Summary of the Invention

[0029] refer to Figures 1 to 5 As shown, the present application discloses a waterproof structure of an exterior wall structure, which includes: an underground exterior wall waterproof structure, a building exterior wall waterproof structure and a roof layer waterproof structure; the underground exterior wall waterproof structure is self-waterproof, wrapped with a waterproof roll, and sealed by end treatment to complete structural waterproofing; the building exterior wall waterproof structure is reinforced with drainage at the door and window openings to complete the waterproofing of the building exterior wall; the roof layer waterproof structure is combined with waterproofing and drainage, and waterproofing of the corresponding position is completed by setting a waterproof reinforcement layer.

[0030] Specifically, the first waterproofing is located in the basement, or in an environment that is soaked in water for a long time. This type of waterproofing is mainly for prevention, and requires structural self-waterproofing, waterproofing membrane wrapping, and sealing treatment of the ends. The overall waterproofing requirements are relatively high. The second waterproofing is located on the ground part of the building's exterior wall, an area where the structure is exposed to the sun and rain for a long time. The waterproofing of this part is mainly for drainage, and the focus of waterproofing is on the openings of external doors and windows. The third waterproofing is roof layer drainage, which involves special parts such as high and low spans, parapets, and pipe trenches. It is also a high-frequency area for leakage points. As long as it is mainly for drainage, combined with drainage and prevention, a waterproof reinforcement layer is made in key areas. The following is an explanation of the three waterproofing of the exterior wall.

[0031] (1) Underground exterior wall waterproof structure The underground exterior wall waterproof structure forms a tic-tac-toe divided area on the outside of the underground exterior wall 3 through the waterproof divided end groove 1. The current conventional waterproof specifications still require structure first and then waterproofing. In fact, this method lacks an effective connection between the structural layer and the waterproof layer. This application targets the root of waterproof design and divides the waterproof into several small units to avoid water leakage to the greatest extent. (The biggest problem with waterproofing is that it is difficult to stop leaks. Once water seeps in, it is difficult to find the leakage point. It is caused by water leakage. A whole area is leaking, but the real source point is difficult to find). The use of split and sliced ​​waterproofing can provide the greatest guarantee for later maintenance, repair and replacement.

[0032] The waterproof dividing end groove 1 is pre-buried in the underground outer wall, and the first waterproof membrane 2 arranged on the outside of the main structure of the underground outer wall is compacted and sealed by the sealing water stop rod 107 waterproof sealant arranged in the waterproof dividing end groove 1.

[0033] Preferably, the underground exterior wall is further provided with an exterior wall protection layer 31 , which is arranged on the outside of the first waterproof membrane 2 , and includes a waterproof protection layer and a decorative layer.

[0034] The underground exterior walls utilize reinforced concrete shear walls to prevent water and soil intrusion into the underground space. However, because shear walls are typically extremely long and tall, the risk of cracking caused by concrete shrinkage and deformation under temperature is difficult to eliminate. This is why waterproofing cannot rely solely on the structure's inherent waterproofing but requires a waterproof layer. While minor cracks in the wall do not affect the structural safety and functionality, they pose a significant risk of leakage. Furthermore, water seeping into the reinforced concrete can cause corrosion, accelerating the deterioration of the components, leading to structural instability and failure, ultimately ending their lifespan. Therefore, waterproofing is crucial, not only because it can affect performance but, more importantly, because waterproofing failure can shorten the lifespan of the structure.

[0035] When pouring the underground exterior wall, the wall casting structure is provided with a steel mesh structure and waterproof segmented end grooves 1 and steel protective layer pads 14 arranged on both sides of the steel mesh structure. The waterproof segmented end grooves 1 and steel protective layer pads 14 separate the steel mesh structure from the casting formwork 15 on both sides, allowing the corresponding area to be injected with concrete slurry, thereby increasing the service life of the underground exterior wall. The steel mesh structure is composed of exterior wall stirrups 11, exterior wall vertical bars 12, and exterior wall transverse bars 13 connected to each other.

[0036] The function of the steel bar protective layer pad 14 is to provide a protective layer for the steel bars of the steel mesh structure to prevent premature corrosion and aging. In this application, the steel bar protective layer pad 14 on one side is replaced with a waterproof segmentation end slot 1. The waterproof segmentation end slot 1 still serves the function of the steel bar protective layer pad 14, and also has the additional function of segmenting the end of the waterproof membrane, dividing the large area of ​​the exterior wall into small units.

[0037] Preferably, when the waterproof segmentation end trough 1 is at the edge of the basement wall, the waterproof segmentation end trough 1 includes: a trough cover 101 and a waterproof segmentation end trough box 103. The trough cover 101 is connected to the top of the waterproof segmentation end trough box 103 via a rotating shaft 102. The waterproof segmentation end trough box 103 is a C-shaped structure box.

[0038] During the process of pouring the underground exterior wall, the groove cover 101 is rotated to the opening of the waterproof segmentation end groove box 103 to complete the sealing of the C-shaped structural box body, preventing cement slurry from entering the groove box; after the underground exterior wall is poured, when the first waterproof membrane 2 is laid, the groove cover 101 is flipped up to open the opening of the waterproof segmentation end groove box 103, and then the first waterproof membrane 2 is wrapped around the sealing water stop rod 107 waterproof sealant and inserted into the groove structure of the waterproof segmentation end groove box 103, and after the sealing is inserted, the waterproof sealant is inserted into the groove structure of the waterproof segmentation end groove box 103. Before sealing the water-stop rod 107 with waterproof sealant, the waterproof dividing end slot box 103 is filled with waterproof sealant, and the sealing water-stop rod 107 with the first waterproof membrane 2 is rolled up and plugged into the bottom of the waterproof dividing end slot box 103. Then, a sealing water-stop rod 107 with waterproof sealant without the first waterproof membrane 2 is squeezed into the waterproof dividing end slot box 103 again. After pressing, the slot cover plate 101 is rotated 180 degrees to complete the sealing of the waterproof dividing end slot box 103, which plays the role of sealing and dispersing water.

[0039] Preferably, the waterproof dividing end groove 1 also includes a first groove claw 106, which is connected to the waterproof dividing end groove box 103 via a groove connecting shaft 104, and the waterproof dividing end groove 1 is fixed on the steel mesh structure through the first groove claw 106, so that the position of the waterproof dividing end groove 1 is stable when the underground exterior wall is cast; and a universal joint 105 is provided at the connection between the groove connecting shaft 104 and the first groove claw 106.

[0040] Preferably, when the waterproof segmented end-end groove is in the middle of the basement wall, the waterproof segmented end-end groove 1 is provided with a double groove structure arranged side by side, including: a waterproof end-end groove 108 and a waterproof fixing groove 109. The waterproof end-end groove 108 and the waterproof fixing groove 109 respectively complete the fixing of the waterproof sealant of the sealing rod 107 wrapped with the first waterproof membrane 2 on the upper and lower sides of the waterproof segmented end-end groove 1 on the basement wall, and the waterproof end-end groove 108 and the waterproof fixing groove 109 are filled with waterproof cementitious material. The waterproof segmented end-end groove is also provided with a second groove claw 111 for completing the fixing of the waterproof segmented end-end groove 1 to the steel mesh structure.

[0041] (2) Waterproof structure of building exterior wall The waterproof structure of the building's exterior wall includes: a wall edging structure set around the door and window openings and an outward slope structure on the top side of the door and window openings.

[0042] Specifically, ground waterproofing is mainly based on drainage. The exterior wall needs to be coated with waterproof mortar. Waterproofing agent and anti-cracking agent need to be added to the material. All openings, including air-conditioning holes, are sloped outward to prevent rainwater ducts, and the edges of the openings are sealed with waterproof mortar.

[0043] For the door and window openings on the ground exterior wall, waterproofing should be done on three sides, namely the lower part and both sides of the opening. Figure 1 This method wraps the wall around the opening to prevent rainwater from intruding. Pre-embedded waterproofing components 401 are installed at the bottom of the door and window openings. These components can be made of metal, plastic, or a rigid, formable polymer material. They are shaped like an I-beam, with one end larger than the other. After the second waterproofing membrane 7 is covered on top of the pre-embedded waterproofing component 401, a matching clamp is used to lock the second waterproofing membrane 7 and the pre-embedded waterproofing component 401 together, preventing water from leaking through the gaps in the opening. During the civil construction above the opening, an overhanging eave is created, and a beak is installed at the bottom of the overhanging eaves.

[0044] (3) Roof waterproof structure The roof is a building structure that comes into direct contact with rainwater. Depending on the structure, it is divided into two types: facade and plane. The facade is mainly for evacuation, while the horizontal roof is mainly for drainage and defense.

[0045] The roof waterproofing structure includes: roof waterproofing membrane, the roof waterproofing membrane is turned up 200mm above the parapet part and is provided with a head strip, fixed with cement nails 504 and caulking with grease 503, and the upper end of the roof waterproofing membrane is covered with a thin iron sheet 502 for waterproofing.

[0046] Preferably, the roof waterproof structure also includes: a large eave 501 arranged on the top of the parapet; a chamfer 506 is set at the corner between the parapet and the roof, and is set on a waterproof additional layer 507, and the roof waterproof membrane is paved and overlapped along the direction of water flow.

[0047] For structures such as scattered water that require secondary construction, it is necessary to avoid "upward seams" and transform vertical seams into horizontal seams through structural transformation to reduce the risk of leakage, increase the water flow path, and play a role in isolation and waterproofing. Specifically, Figure 5As shown, when the primary structure 601 and the secondary structure 602 (a later construction site, which can also be glass, metal, or other components) are connected, waterproof joint treatment must be properly carried out. First, waterproof expansion strips 603 are installed at the butt joints as the first waterproofing layer. Next, waterproof sealant 605 is applied to the joints. At the same time, isolation strips 604 are added here. The material is not limited. The reason for adding isolation strips 604 here is to form a "two-sided adhesive" on the adhesive surface, avoiding "three-sided adhesive". The adhesive itself is flexible, but it is subjected to force at three points, which can easily form triangular cracks. Therefore, the use of isolation strips 604 avoids the occurrence of three-sided adhesive.

[0048] This application addresses the root cause of waterproofing by focusing on the principle of water release. Different waterproofing measures are adopted for different application environments and waterproofing levels, dividing large waterproof areas into smaller units to facilitate waterproofing maintenance. Multiple levels of waterproofing are tightly connected, and pre-buried waterproofing membrane structural nodes are reserved during structural construction to facilitate collaborative waterproofing operations. A waterproof split-seam end slot design is also adopted to achieve synchronous coordination between structural waterproofing and membrane waterproofing, improving waterproofing and weather resistance, and extending the service life of the structure.

[0049] The above description is only a preferred embodiment of the present application and is not intended to limit the present application. Any modifications, equivalent replacements and improvements made within the spirit and principles of the present application should be included in the scope of protection of the present application.
