Description

Technical Field

[0001] The invention relates to the technical field of parapet wall construction, and in particular to a parapet wall anti-leakage structure and a construction method thereof. Background Art

[0002] A parapet is a term used in architectural design to refer to the perimeter or low wall of a building's roof. It is usually used at the edge of a roof to prevent people or objects from falling from the roof, or in some cases, to beautify the building's exterior.

[0003] At present, due to the construction characteristics of the building itself, the joint between the parapet and the roof is easily affected by thermal expansion and contraction, which leads to cracks. These cracks will 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 is not drained for a long time, the rainwater will soak and affect the isolation and waterproof layer of the roof, especially in an environment with wind and sun, the water will penetrate into the building through the cracks, reducing the service life of the waterproof layer.

[0004] In addition, the accumulated rainwater is often exposed to high temperatures, and the water vapor expands, further exacerbating the expansion of cracks, resulting in more cracks in the building, affecting its normal use. At the same time, due to the poor rigidity and integrity of common parapet walls, they are easily affected by the expansion thrust of the roof waterproofing layer and protective layer, causing outward movement, resulting in lower safety and easy to produce larger cracks. Under the influence of the temperature difference between day and night, the thermal expansion and contraction between the parapet wall and the roof is more obvious, which is easy to form new cracks, further exacerbating the problem of rainwater leakage.

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

[0028] 1. The parapet anti-leakage structure and the construction method thereof, by combining a plurality of steel bars to form a steel cage, the overall strength is greatly improved, and the steel cage arrangement can effectively increase the stability and bearing capacity of the parapet structure, improve the seismic performance and enhance the durability, and waterproof coating glue is arranged on each steel bar of the steel cage to increase the waterproof sealing, and secondly, geosynthetics are added between the parapet structure and the longitudinal wall, and the geosynthetics can play the role of reinforcement, reinforcement, anti-seepage, isolation, drainage, anti-filtration and protection, further maintaining the bearing capacity and stability of the parapet structure, and not easy to cause displacement, and at the same time, a second waterproof glue layer is arranged at the bottom of the geosynthetics to play an anti-seepage effect.

[0029] 2. The anti-leakage structure of the parapet and the construction method thereof can effectively block the penetration of water and play a waterproof role through the water resistance of the first waterproof membrane, the second waterproof membrane and the third waterproof membrane, and can also ensure that the accumulated water is effectively discharged. There are gaps between the multiple waterproof connection structures. At the same time, the hydrophobic surface and the longitudinal wall slope decrease to the right, thereby guiding the water to be discharged smoothly to the right, which is convenient for drainage.

[0030] 3. The parapet wall anti-leakage structure and its construction method can form a good drainage channel through the hydrophobicity of the waterproof structure, the oblique arrangement of the top wall, the longitudinal wall and the second hydrophobic structure, and the gaps between the waterproof connection structures, so that water can be discharged in time to avoid the accumulation of water, thereby reducing the probability of water seepage. In addition, the second waterproof membrane and the third waterproof membrane form a U-shaped structure in the sealing groove, which can effectively play a role in sealing and waterproofing. In combination with the sealing of the third waterproof adhesive layer, the waterproof performance is greatly improved. Secondly, the hydrophobic slope is an inclined surface, and the height of the connection point between the guide surface and the hydrophobic slope is small. At the connection height between the guide surface and the longitudinal wall, the hydrophobic slope can be drained smoothly to prevent water from passing under the guide surface, thereby improving the anti-permeability. If water leaks from under the guide surface, water molecules will accumulate on the vertical surface of the third waterproof adhesive layer. The third waterproof adhesive layer is arc-shaped below, so that water molecules can be smoothly discharged downward through the vertical surface, thereby playing a double waterproofing role. By preventing water penetration and cooperating with good hydrophobicity, water accumulation is avoided, so that the waterproof structure, the second hydrophobic structure and the waterproof connection structure can better play their performance, keep the structure dry, and further avoid water seepage.

The first hydrophobic structure 300 includes a top plate 301, and the top plate 301 is shaped like a ridge. The ridge shape is set so that the top plate 301 can more easily guide rainwater to be discharged to both sides to avoid rainwater residue. A first waterproof adhesive layer 303 is provided at the vertical connection between the top plate 301 and the parapet structure 100, and the first waterproof adhesive layer 303 is laid downward along the parapet structure 100. The first waterproof adhesive layer 303 can seal the connection between the first waterproof membrane 501 and the laying groove 101 to improve the waterproof and anti-penetration effects. The reinforced concrete structure formed by combining steel bars and concrete has high durability and can resist erosion and damage in the natural environment. It is connected 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. The waterproof sealing layer 302 can play a waterproof sealing role between the top plate 301 and the first waterproof adhesive layer 303 to avoid water seepage. A plurality of steel cages 401 are embedded in the longitudinal wall 400, and the steel cages 401 are arranged in the parapet structure 100. The steel cages 401 play the role of a skeleton in the parapet, enhancing the wind pressure resistance and overturning resistance of the wall, and preventing the wall from collapsing or being damaged.

[0046] A hydrophobic surface 201 is provided above the top wall 200, and a waterproof structure 500 is provided on the hydrophobic surface 201. The waterproof structure 500 is laid upward along the waterproof connection structure 600 to the parapet structure 100 and is connected to the first hydrophobic structure 300. The waterproof connection structure 600 includes a geosynthetic material 602 and a plurality of waterproof coating adhesives 603. The geosynthetic material 602 can enhance the bearing capacity and shear strength of the parapet structure 100. At the same time, the geosynthetic material 602 has excellent anti-seepage, isolation and protection properties, thereby effectively improving the stability, bearing capacity and disaster resistance of the parapet structure 100. A plurality of waterproof coating adhesives 603 are coated on a single steel bar of the same steel cage 401, and the waterproof coating adhesive 603 seals the bottom of the steel cage 401 for waterproofing. Water treatment, and in conjunction with geosynthetics 602, multiple anti-seepage effects can be achieved, and it is connected to the first waterproof membrane 501, multiple waterproof coating adhesives 603 are arranged in the geosynthetics 602, and the steel cage 401 is arranged in the geosynthetics 602. The geosynthetics 602 are assembled below the parapet structure 100, and the bottom of the geosynthetics 602 is connected to the first waterproof membrane 501 through a second waterproof adhesive layer 601 arranged around it. The bottom of the geosynthetics 602 can be sealed and waterproofed through the second waterproof adhesive layer 601, thereby further improving the waterproof performance and avoiding the risk of water seepage in the gap between the geosynthetics 602 and the first waterproof membrane 501. One end of the first waterproof membrane 501 is also laid upward on the side of the geosynthetics 602.

[0047] In this embodiment: by combining multiple steel bars to form a steel cage 401, the overall strength is greatly improved, and the setting of the steel cage 401 can effectively increase the stability and bearing capacity of the parapet structure 100, improve the seismic performance and enhance the durability, and waterproof coating glue 603 is arranged on each steel bar of the steel cage 401 to increase the waterproof sealing. Secondly, geosynthetics 602 are added between the parapet structure 100 and the longitudinal wall 400. The geosynthetics 602 can play the role of reinforcement, reinforcement, anti-seepage, isolation, drainage, anti-filtration and protection, further maintaining the bearing capacity and stability of the parapet structure 100, and is not easy to cause displacement. At the same time, a second waterproof glue layer 601 is arranged at the bottom of the geosynthetics 602 to play an anti-seepage effect.

[0048] Example 2: Reference Figure 2 and Figures 4 to 5 The parapet anti-leakage structure includes a waterproof structure 500, and the waterproof structure 500 includes a second waterproof membrane 502. The first waterproof membrane 501, the second waterproof membrane 502 and the third waterproof membrane 702 have the characteristics of blocking moisture penetration, ensuring that moisture cannot penetrate into the interior of the building structure, and also have the functions of water conduction and drainage, water resistance, good mechanical strength, good elongation, fracture resistance and erosion resistance, ensuring that the waterproof effect is optimal and the service life is improved. The second waterproof membrane 502 is laid on the hydrophobic surface 201, and the height of the hydrophobic surface 201 decreases to the right, and the slope of the hydrophobic surface 201 decreases to the right, so that the hydrophobic surface 201 can smoothly perform the hydrophobic operation and reduce moisture residue. The longitudinal wall 400 continues to decrease to the right along the slope of the hydrophobic surface 201, so that the moisture can continue to be guided to the right for discharge. The top of the longitudinal wall 400 is from the left The slope decreases to the right, and it is laid to the right on the top wall and the hydrophobic slope 705, and then laid back along the turning point of the hydrophobic slope 705 and the guide surface 706 into the sealing groove 703, forming a U-shaped structure in the sealing groove 703, and a U-shaped structure is formed in the sealing groove 703 by the second waterproof membrane 502 and the third waterproof membrane 702, so as to increase 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, so as to prevent warping. 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 structure 100 and enters the laying groove 101. A plurality of waterproof connection structures 600 are arranged below the parapet 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 the penetration of moisture and play a waterproof role. It can also ensure that the accumulated moisture is effectively discharged, and there are gaps between the multiple waterproof connection structures 600. At the same time, the hydrophobic surface 201 and the longitudinal wall 400 are inclined to the right in a decreasing manner, thereby guiding the moisture to be discharged smoothly to the right, which is convenient for hydrophobicity.

[0050] Example 3: Reference Figure 4 and Figure 5 The parapet anti-leakage structure includes a second hydrophobic structure 700, which includes a hydrophobic area 701. The hydrophobic area 701 includes a connecting surface 707, a flow guide surface 706 and a hydrophobic slope 705. The hydrophobic slope 705 is arranged with a slope, which can play a good hydrophobic role. The flow guide surface 706, the hydrophobic slope 705 and the connecting surface 707 are arranged on the upper and lower sides and the left side of the hydrophobic area 701, respectively. The connecting surface 707 is installed on one side of the longitudinal wall 400. A sealing groove 703 is opened below the flow guide surface 706. The waterproof structure 500 extends to the right to the hydrophobic slope 705, and then enters the sealing groove 703 along the flow guide surface 706.

[0051] The waterproof structure 500 includes a second waterproof membrane 502, which is laid on the hydrophobic surface 201, and is laid to the right on the top wall and the hydrophobic slope 705, and then laid back along the turning point of the hydrophobic slope 705 and the guide surface 706 into the sealing groove 703, forming a U-shaped structure in the sealing groove 703. The height of the hydrophobic surface 201 decreases to the right, and 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. The different connection point heights at both ends of the guide surface 706 prevent water molecules from being guided to the left, so that water molecules can be smoothly discharged through the hydrophobic slope 705, avoiding subsequent damage to the wall. A third waterproof membrane 702 is laid above the second waterproof membrane 502 located on the hydrophobic slope 705, and one end of the third waterproof membrane 702 is connected to the first A waterproof roll 501 is connected by a waterproof sealant, and a third waterproof roll 702 is laid downward along the second waterproof roll 502, and laid back along the turning point of the second waterproof roll 502, and at the same time, a U-shaped structure is formed at the part where the second waterproof roll 502 enters the sealant, and a third waterproof adhesive layer 704 is provided at the angle between the guide surface 706 and the longitudinal wall 400, and the third waterproof adhesive layer 704 closes the U-shaped structure formed by the second waterproof adhesive layer 601 and the third waterproof adhesive layer 704, and the bottom 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, through which moisture can be accumulated, and at the same time, the arc surface is used to make water molecules accumulate smoothly on the vertical surface, preventing water molecules from flowing to the longitudinal wall 400, thereby achieving a secondary waterproof effect, and making the protection effect of the longitudinal wall 400 better. In one embodiment, a layered or meshed anti-sun and anti-cracking material can be provided at the third waterproof adhesive layer 704. In one example, a high-density mesh polyethylene material is provided at the U-shaped structure, and then the adhesive layer 704 is coated, which can improve the sun-proof and crack-proof performance of the third adhesive layer 704. This prevents the adhesive layer from falling off and the roll material from warping after long-term exposure to the sun and rain. The polyethylene mesh can be provided at the edge of the third waterproof adhesive layer 704, or the entire surface to be sealed.

[0052] In this embodiment: through 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, and the gaps between the waterproof connection structures 600, a good drainage channel can be formed, and water can be discharged in time to avoid the accumulation of water, thereby reducing the probability of water seepage. In addition, the second waterproof roll 502 and the third waterproof roll 702 form a U-shaped structure in the sealing groove 703, which can effectively play a role in sealing and waterproofing. In combination with the sealing of the third waterproof adhesive layer 704, the waterproof performance is greatly improved. Secondly, the hydrophobic slope 705 is a slope, and the height of the connection point between the guide surface 706 and the hydrophobic slope 705 is less than the guide surface. The connection height between the flow surface 706 and the longitudinal wall 400 allows the hydrophobic slope 705 to drain water smoothly, preventing water from passing under the guide surface 706, thereby improving the anti-permeability. If water leaks from under the guide surface 706, water molecules will accumulate on the vertical surface of the third waterproof adhesive layer 704. The bottom of the third waterproof adhesive layer 704 is arc-shaped, so that water molecules can be smoothly discharged downward through the vertical surface, thereby achieving a double waterproof effect. By preventing water penetration and cooperating with good hydrophobicity to avoid water accumulation, the waterproof structure 500, the second hydrophobic structure 700 and the waterproof connection structure 600 can better exert their performance and keep the structure dry, thereby further avoiding water seepage.

A third waterproof adhesive layer 704 is arranged at the U-shaped structure of the second waterproof roll 502 and the third waterproof roll 702, and at the angle between the guide surface 706 and the longitudinal wall 400.

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, and a waterproof sealing layer 302 is laid between the angle between the first waterproof adhesive layer 303 and the top plate 301 for further waterproofing.

[0062] The present invention combines a plurality of steel bars to form a steel cage, which greatly improves the overall strength. The steel cage can effectively increase the stability and bearing capacity of the parapet structure, improve the seismic performance and enhance the durability. Waterproof coating glue is arranged on each steel bar of the steel cage to increase the waterproof sealing. Secondly, geosynthetics are added between the parapet structure and the longitudinal wall.
