Description

Technical Field

[0001] This invention relates to the field of parapet wall construction technology, and in particular to a parapet wall anti-seepage structure and its construction method. Background Technology

[0002] A parapet wall is a term in architectural design, referring to a low wall or perimeter wall around the roof of a building. It is typically used at the edge of a roof to prevent people or objects from falling off, or in some cases, to enhance the building's appearance.

[0003] Currently, due to the inherent construction characteristics of buildings, the junction between the parapet wall and the roof is susceptible to thermal expansion and contraction, leading to cracks. These cracks can cause water seepage and leakage, especially after rainfall, when rainwater tends to accumulate in this area and is difficult to drain. If the accumulated water does not drain for a long time, it will soak and damage the roof's waterproofing layer, especially under wind and sun exposure, where moisture can seep into the building's interior through the cracks, reducing the lifespan of the waterproofing layer.

[0004] Furthermore, accumulated rainwater is often exposed to high temperatures and direct sunlight, causing moisture expansion and further exacerbating crack growth, leading to more cracks in the building and affecting its normal use. Meanwhile, parapet walls, due to their relatively poor rigidity and integrity, are easily affected by the expansion thrust of the roof's waterproofing and protective layers, causing them to shift outwards, resulting in lower safety and a higher likelihood of developing larger cracks. Under the influence of diurnal temperature variations, the thermal expansion and contraction between the parapet wall and the roof becomes more pronounced, easily forming new cracks and further exacerbating rainwater leakage problems.

[0005] To address the aforementioned problems, this invention proposes a parapet wall anti-seepage structure and its construction method. Summary of the Invention

[0006] The purpose of this invention is to address the problem of rainwater accumulation and poor drainage after rainfall. If the accumulated water is not drained for an extended period, it will soak and damage the roof's waterproofing layer. Furthermore, the accumulated rainwater is often exposed to high temperatures and sunlight, causing moisture expansion and further exacerbating crack growth, leading to more cracks in the building. Simultaneously, common parapet walls, due to their poor rigidity and integrity, are easily affected by the expansion thrust of the roof's waterproofing and protective layers, resulting in outward displacement, lower safety, and a tendency to develop larger cracks. Under the influence of diurnal temperature variations, the thermal expansion and contraction between the parapet wall and the roof becomes even more pronounced, easily forming new cracks and further exacerbating rainwater leakage problems. Therefore, this invention proposes a parapet wall waterproofing structure and its construction method.

[0007] To achieve the above objectives, the present invention adopts the following technical solution: This application provides a parapet wall anti-seepage structure, including a parapet wall structure, a top wall of a building, and a longitudinal wall.

At the same time, a matching U-shaped structure is formed at the part where the second waterproof membrane enters the sealant.

The geosynthetic material is assembled below the parapet wall structure. The bottom of the geosynthetic material is connected to the first waterproof membrane by a second waterproof adhesive layer around it. One end of the first waterproof membrane is also laid upward on the side of the geosynthetic material.

[0018] A construction method for a parapet wall waterproofing structure includes the following steps:

[0019] S1. Construction Preparation

[0020] Understand the design requirements, dimensions, and material requirements of the parapet wall, and prepare the necessary construction materials and tools according to the design requirements. Next, determine the location of the parapet wall structure according to the construction drawings and lay out the lines for positioning.

[0021] S2, Template erection

[0022] Based on the height and shape of the parapet wall structure, select appropriate formwork materials and install the formwork in place according to the design requirements. The formwork should be vertical and horizontal. Then, pour concrete inside the formwork, paying attention to the thickness and density of the concrete. Use a vibrator to compact the concrete and remove air bubbles. After the concrete is poured, cure it in time to ensure its strength and durability. After the concrete has cured to a certain strength, remove the formwork.

[0023] S3, Waterproofing Construction

[0024] Before the parapet wall structure is poured, a second waterproof membrane is laid on the drainage surface, longitudinal wall and drainage slope. The second waterproof membrane bypasses the joint between the drainage slope and the guide surface, is laid on the guide surface, and forms a U-shaped structure in the sealing groove.

[0025] After the parapet wall structure is formed, a third waterproof membrane is laid on the right side of the second waterproof membrane. The third waterproof membrane extends to the guide surface and forms a U-shaped structure at the end of the second waterproof membrane. A third waterproof adhesive layer is laid at the U-shaped structure of the second and third waterproof membranes, as well as at the angle between the guide surface and the longitudinal wall. The right side of the third waterproof adhesive layer is vertically treated, and the bottom is arranged in an arc shape. Then, a second waterproof adhesive layer is laid at the bottom of the geosynthetic material for waterproofing.

[0026] Then, the first waterproof membrane is laid on the second waterproof membrane, with the dimensions designed as needed, so that the first waterproof membrane is laid upward along the bottom of the geosynthetic material, extending from the parapet structure into the laying groove. Finally, the first waterproof adhesive layer is laid downward on the side above the parapet structure, covering the laying groove and one side of the first waterproof membrane. A waterproof sealant layer is then laid between the first waterproof adhesive layer and the top slab for further waterproofing.

[0027] Compared with the prior art, the present invention provides a parapet wall anti-seepage structure and its construction method, which has at least one of the following beneficial effects:

[0028] 1. The parapet wall seepage prevention structure and its construction method, by combining multiple steel bars to form a steel cage, significantly improves the overall strength. The steel cage effectively increases the stability and load-bearing capacity of the parapet wall structure, improves seismic performance and enhances durability. Each steel bar in the steel cage is coated with waterproof adhesive to increase waterproof sealing. Secondly, geosynthetic material is added between the parapet wall structure and the longitudinal wall. The geosynthetic material can play the roles of reinforcement, strengthening, seepage prevention, isolation, drainage, filtration and protection, further maintaining the load-bearing capacity and stability of the parapet wall structure and making it less prone to displacement. At the same time, a second waterproof adhesive layer is placed at the bottom of the geosynthetic material to achieve the effect of preventing seepage.

[0029] 2. The parapet wall waterproofing structure and its construction method, through the water resistance of the first, second and third waterproof membranes, can effectively block water penetration and play a waterproofing role. It can also ensure that the accumulated water is effectively discharged. In addition, there are gaps between the multiple waterproof connection structures, and the drainage surface and the longitudinal wall slope decrease to the right, which can guide water to drain smoothly to the right, facilitating drainage.

[0030] 3. The parapet wall waterproofing structure and its construction method utilize the hydrophobicity of the waterproofing structure, the oblique arrangement of the top wall, longitudinal walls, and the second hydrophobic structure, combined with the gaps created between the waterproof connection structures, to form a good drainage channel. Water can be discharged promptly, preventing water accumulation and reducing the chance of seepage. Furthermore, the second and third waterproof membranes form a U-shaped structure in the sealing groove, effectively sealing and waterproofing. Combined with the sealing of the third waterproof adhesive layer, the waterproofing performance is significantly improved. Additionally, the hydrophobic slope is oblique, and the connection point between the guide surface and the hydrophobic slope is low. The connection height between the guide surface and the longitudinal wall allows for smooth drainage of the hydrophobic slope, preventing water from flowing under the guide surface and improving impermeability. If water leaks below the guide surface, water molecules accumulate on the vertical surface of the third waterproof adhesive layer. The lower part of the third waterproof adhesive layer is curved, allowing water molecules to be smoothly discharged downwards through the vertical surface, thus achieving a double waterproofing effect. By preventing water penetration and combining good hydrophobicity, water accumulation is avoided, allowing the waterproof structure, the second hydrophobic structure, and the waterproof connection structure to better perform their functions, maintaining the dryness of the structure, and further preventing water seepage.

Detailed Implementation

[0042] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0043] In the description of this invention, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this invention.

[0044] Example 1: Refer to Figures 1 to 3 and Figures 5 to 10 The parapet wall waterproofing structure provided in this application includes a parapet wall structure 100, which is installed on a longitudinal wall 400. A first drainage structure 300 is provided above the parapet wall structure 100, and multiple waterproof connection structures 600 are provided below the parapet wall structure 100. A top wall 200 and a second drainage structure 700 are respectively provided on both sides of the longitudinal wall 400.

[0045] In detail, a laying groove 101 is provided on the upper side of one side of the parapet structure 100. The upper part of the laying groove 101 is a vertical surface, and the lower part of the laying groove 101 is a sloping surface. The first drainage structure 300 includes a top plate 301, which is shaped like a roof ridge. This ridge shape facilitates rainwater drainage to both sides, preventing water residue. A first waterproof adhesive layer 303 is provided at the vertical connection between the top plate 301 and the parapet wall structure 100, and this layer extends downwards along the parapet wall structure 100. The first waterproof adhesive layer 303 seals the connection between the first waterproof membrane 501 and the laying groove 101, improving waterproofing and seepage prevention. The reinforced concrete structure, formed by the combination of steel bars and concrete, has high durability and can resist erosion and damage from the natural environment. It connects to the side of the first waterproof membrane 501 at the laying groove 101. A waterproof sealing layer 302 is provided at the angle formed between the first waterproof adhesive layer 303 and the top plate 301. This waterproof sealing layer 302 ensures a waterproof seal between the top plate 301 and the first waterproof adhesive layer 303, preventing water seepage. Multiple steel reinforcement cages 401 are embedded in the longitudinal wall 400, and the steel reinforcement cages 401 are located in the parapet wall structure 100. The steel reinforcement cages 401 act as a skeleton in the parapet wall, enhancing the wall's resistance to wind pressure and overturning, and preventing the wall from collapsing or being damaged.

[0046] A drainage surface 201 is provided above the top wall 200, and a waterproof structure 500 is provided on the drainage surface 201. The waterproof structure 500 is laid upward along the waterproof connection structure 600 onto the parapet wall structure 100 and connected to the first drainage structure 300. The waterproof connection structure 600 includes geosynthetic material 602 and multiple waterproof coatings 603. The geosynthetic material 602 can enhance the load-bearing capacity and shear strength of the parapet wall structure 100. At the same time, the geosynthetic material 602 has excellent seepage prevention, isolation and protection properties, thereby effectively improving the stability, load-bearing capacity and disaster resistance of the parapet wall structure 100. Multiple waterproof coatings 603 cover individual steel bars of the same steel cage 401, and the waterproof coatings 603 seal the bottom of the steel cage 401. Water treatment, combined with geosynthetic material 602, can achieve multiple seepage prevention effects and is connected to the first waterproof membrane 501. Multiple waterproof coating adhesives 603 are set in geosynthetic material 602, and the steel cage 401 is set in geosynthetic material 602. Geosynthetic material 602 is assembled under the parapet wall structure 100. The bottom of geosynthetic material 602 is connected to the first waterproof membrane 501 by a second waterproof adhesive layer 601 around it. The second waterproof adhesive layer 601 can seal and waterproof the bottom of geosynthetic material 602, thereby further improving the waterproof performance and avoiding the risk of water seepage from the gap between geosynthetic material 602 and the first waterproof membrane 501. One end of the first waterproof membrane 501 is also laid upward on the side of geosynthetic material 602.

[0047] In this embodiment: by combining multiple steel bars to form a steel cage 401, the overall strength is greatly improved. Moreover, the steel cage 401 can effectively increase the stability and load-bearing capacity of the parapet wall structure 100, improve seismic performance and enhance durability. Each steel bar of the steel cage 401 is covered with waterproof adhesive 603, thereby increasing waterproof sealing. Secondly, geosynthetic material 602 is added between the parapet wall structure 100 and the longitudinal wall 400. Geosynthetic material 602 can play the roles of reinforcement, strengthening, seepage prevention, isolation, drainage, filtration and protection, further maintaining the load-bearing capacity and stability of the parapet wall structure 100 and making it less prone to displacement. At the same time, a second waterproof adhesive layer 601 is arranged at the bottom of the geosynthetic material 602, which can play the role of seepage prevention.

[0048] Example 2: Refer to Figure 2 and Figures 4 to 5 The parapet wall waterproofing structure includes a waterproof structure 500, which includes a second waterproof membrane 502. The first waterproof membrane 501, second waterproof membrane 502, and third waterproof membrane 702 have the property of blocking water penetration, ensuring that water cannot penetrate into the building structure. They also have functions of water drainage, water resistance, good mechanical strength, good elongation, fracture resistance, and erosion resistance, ensuring optimal waterproofing effect and extending service life. The second waterproof membrane 502 is laid on the drainage surface 201, with the height and slope of the drainage surface 201 decreasing to the right, allowing for smooth drainage operations and reducing water residue. The longitudinal wall 400 continues to decrease to the right from the slope of the drainage surface 201, thus guiding water to drain to the right. The top of the longitudinal wall 400 starts from the left... The waterproof membrane gradually decreases towards the right and is laid on the top wall and the drainage slope 705. Then, it is laid back along the inflection point of the drainage slope 705 and the guide surface 706 into the sealing groove 703, forming a U-shaped structure in the sealing groove 703. The second waterproof membrane 502 and the third waterproof membrane 702 form a U-shaped structure in the sealing groove 703, thereby increasing the sealing performance. At the same time, the third waterproof adhesive layer 704 can seal the ends of the second waterproof membrane 502 and the third waterproof membrane 702, thereby preventing the edges from curling up. The first waterproof membrane 501 is laid above the second waterproof membrane 502, and the first waterproof membrane 501 extends to the right edge of the longitudinal wall 400. The first waterproof membrane 501 is also laid upward along the parapet wall structure 100 and enters the laying groove 101. Multiple waterproof connection structures 600 are provided below the parapet wall structure 100.

[0049] In this embodiment, the water resistance of the first waterproof membrane 501, the second waterproof membrane 502, and the third waterproof membrane 702 can effectively block water penetration and play a waterproof role. In addition, it can also ensure that the accumulated water is effectively discharged. Furthermore, there are gaps between the multiple waterproof connection structures 600. At the same time, the water-repellent surface 201 and the inclined surface of the longitudinal wall 400 decrease to the right, which can guide water to drain smoothly to the right and facilitate drainage.

[0050] Example 3: Reference Figure 4 and Figure 5 The parapet wall seepage prevention structure includes a second drainage structure 700, which includes a drainage area 701. The drainage area 701 includes a connecting surface 707, a guiding surface 706, and a drainage slope 705. The slope of the drainage slope 705 can play a good drainage role. The guiding surface 706, the drainage slope 705, and the connecting surface 707 are respectively located on the upper and lower surfaces and the left side of the drainage area 701. The connecting surface 707 is installed on one side above the longitudinal wall 400. A sealing groove 703 is opened below the guiding surface 706. The waterproof structure 500 extends to the right to the drainage slope 705 and then enters the sealing groove 703 along the guiding surface 706.

[0051] The waterproof structure 500 includes a second waterproof membrane 502, which is laid on the hydrophobic surface 201 and extends to the right onto the top wall and the hydrophobic slope 705. It then extends back along the inflection point of the hydrophobic slope 705 and the guide surface 706 into the sealing groove 703, forming a U-shaped structure. The height of the hydrophobic surface 201 decreases to the right. The height of the connection point between the guide surface 706 and the longitudinal wall 400 is greater than the height of the connection point between the guide surface 706 and the hydrophobic slope 705. This difference in connection height at both ends of the guide surface 706 prevents water molecules from being guided to the left, allowing them to pass smoothly through the hydrophobic slope 705 and avoid subsequent damage to the wall. A third waterproof membrane 702 is laid above the second waterproof membrane 502 on the hydrophobic slope 705. One end of the third waterproof membrane 502 is connected to the first waterproof membrane 502. A waterproof membrane 501 is connected by a waterproof sealant, and a third waterproof membrane 702 is laid downwards along the second waterproof membrane 502 and backwards along the inflection point of the second waterproof membrane 502. Simultaneously, a suitable U-shaped structure is formed at the portion of the second waterproof membrane 502 where it enters the sealant. A third waterproof adhesive layer 704 is provided at the angle between the guide surface 706 and the longitudinal wall 400. The third waterproof adhesive layer 704 seals the U-shaped structure formed by the second waterproof adhesive layer 601 and the third waterproof adhesive layer 704. The lower part of the third waterproof adhesive layer 704 is an arc surface, and the right side of the third waterproof adhesive layer 704 is a vertical surface. Moisture can accumulate on the vertical surface, and the arc surface allows water molecules to accumulate smoothly on the vertical surface, preventing water molecules from flowing towards the longitudinal wall 400, thus achieving a secondary waterproofing effect and improving the protective effect of the longitudinal wall 400. In one embodiment, a layered or mesh-like sun-resistant and crack-resistant material can be provided at the third waterproof adhesive layer 704. In one example, a high-density mesh polyethylene material is placed at the U-shaped structure, and then coated with adhesive layer 704, which improves the sun protection and crack resistance of the third adhesive layer 704. This prevents the adhesive layer from peeling off and the roll material from curling up after prolonged exposure to sun and rain. The polyethylene mesh can be placed at the edge of the third waterproof adhesive layer 704 or on the entire surface to be sealed.

[0052] In this embodiment: the hydrophobicity of the waterproof structure 500, the oblique arrangement of the top wall 200, the longitudinal wall 400, and the second hydrophobic structure 700, combined with the gaps created between the waterproof connection structures 600, form a good drainage channel, allowing water to drain out promptly and preventing water accumulation, thus reducing the chance of water seepage. Furthermore, the second waterproof membrane 502 and the third waterproof membrane 702 form a U-shaped structure in the sealing groove 703, effectively sealing and waterproofing. Combined with the sealing effect of the third waterproof adhesive layer 704, the waterproof performance is significantly improved. Additionally, the hydrophobic slope 705 is an oblique surface, and the height of the connection point between the guide surface 706 and the hydrophobic slope 705 is less than that of the guide surface 706. The connection height between the flow surface 706 and the longitudinal wall 400 allows the drainage slope 705 to drain water smoothly, preventing water from flowing under the flow surface 706 and improving impermeability. If water leaks under the flow surface 706, water molecules accumulate on the vertical surface of the third waterproof adhesive layer 704. The lower part of the third waterproof adhesive layer 704 is arc-shaped, allowing water molecules to be smoothly discharged downward through the vertical surface, thus achieving a double waterproof effect. By preventing water penetration and combining good hydrophobicity, water accumulation is avoided, allowing the waterproof structure 500, the second hydrophobic structure 700, and the waterproof connection structure 600 to better perform their functions, maintaining the dryness of the structure, and further preventing water seepage.

[0053] A construction method for a parapet wall waterproofing structure includes the following steps:

[0054] S1. Construction Preparation

[0055] Understand the design requirements, dimensions, and material requirements of the parapet wall, and prepare the necessary construction materials and tools according to the design requirements. Next, determine the position of the parapet wall structure 100 according to the construction drawings and lay out the positioning lines.

[0056] S2, Template erection

[0057] Based on the height and shape of the parapet wall structure, select appropriate formwork materials and install the formwork in place according to the design requirements. The formwork should be vertical and horizontal. Then, pour concrete inside the formwork, paying attention to the thickness and density of the concrete. Use a vibrator to compact the concrete and remove air bubbles. After the concrete is poured, cure it in time to ensure the strength and durability of the concrete. After the concrete has cured to a certain strength, remove the formwork.

[0058] S3, Waterproofing Construction

[0059] Before the parapet wall structure 100 is poured, a second waterproof membrane 502 is laid on the drainage surface 201, the longitudinal wall 400 and the drainage slope 705. The second waterproof membrane 502 bypasses the joint between the drainage slope 705 and the guide surface 706, is laid on the guide surface 706, and forms a U-shaped structure in the sealing groove 703.

[0060] After the parapet wall structure 100 is formed, a third waterproof membrane 702 is laid on the right side of the second waterproof membrane 502. The third waterproof membrane 702 extends to the guide surface 706 and forms a U-shaped structure at the end of the second waterproof membrane 502. A third waterproof adhesive layer 704 is laid at the U-shaped structure of the second waterproof membrane 502 and the third waterproof membrane 702, as well as at the angle between the guide surface 706 and the longitudinal wall 400. The right side of the third waterproof adhesive layer 704 is vertically treated, and the bottom is arranged in an arc shape. Then, a second waterproof adhesive layer 601 is laid at the bottom of the geosynthetic material 602 for waterproofing.

[0061] Then, the first waterproof membrane 501 is laid on the second waterproof membrane 502. The dimensions are designed according to the requirements, so that the first waterproof membrane 501 is laid upward along the bottom of the geosynthetic material 602, so that the first waterproof membrane 501 extends from the parapet structure 100 to the laying groove 101. Finally, the first waterproof adhesive layer 303 is laid downward on the side above the parapet structure 100, so that the first waterproof adhesive layer 303 covers the laying groove 101 and covers one side of the first waterproof membrane 501. A waterproof sealing layer 302 is laid between the first waterproof adhesive layer 303 and the top plate 301 for further waterproofing treatment.

[0062] This invention significantly enhances the overall strength by combining multiple steel bars to form a steel cage. The steel cage effectively increases the stability and load-bearing capacity of the parapet wall structure, improves seismic performance, and enhances durability. Each steel bar in the cage is coated with waterproof adhesive, increasing waterproof sealing. Furthermore, geosynthetic material is added between the parapet wall structure and the longitudinal wall. This geosynthetic material serves to reinforce, strengthen, prevent seepage, isolate, drain, filter, and protect, further maintaining the load-bearing capacity and stability of the parapet wall structure and preventing displacement. Simultaneously, a second waterproof adhesive layer is applied to the bottom of the geosynthetic material, providing an anti-seepage effect.

[0063] The above are merely preferred embodiments of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
