Description

Technical Field

[0001] This utility model relates to the field of building waterproofing technology, and in particular to a waterproof sealing system for the gaps between gutters and parapet walls. Background Technology

[0002] Industrial plants often employ reinforced concrete frame structures, primarily composed of roof trusses, columns, and foundations. Columns are the main vertical load-bearing components, with the roof trusses located atop the columns, forming the upper part of the structure. Their primary function is to support the roof and evenly distribute the roof load to the columns, which then transfer the load to the foundation. In reinforced concrete frame structures, the roof drainage system is a crucial component, primarily used to collect and drain rainwater, preventing rainwater accumulation that could damage or leak the roof. Currently, roof drainage systems often employ internal gutters, where the gutters are located in the gap between the parapet wall and the roof truss structure. Because the gutters are located inside the parapet wall, internal gutters offer the advantage of enhancing the plant's appearance.

[0003] A parapet wall is a low wall surrounding the roof of a building. However, in some cases, when the parapet wall needs to be designed to be relatively high, connecting adjacent parapet walls with fixed columns helps improve the overall stability and seismic performance of the building. Furthermore, relevant regulations require that when the parapet wall needs to be designed to be relatively high, the thickness dimension of the cross-section of the fixed column connecting adjacent parapet walls must be greater than the thickness of the parapet wall. In this case, the location for the drainage gutter between the roof truss structure and the parapet wall structure is not a straight line viewed longitudinally, but rather a bend protruding towards the roof truss at the fixed column of the adjacent parapet wall. Generally, the number of bends is the same as the number of fixed columns used to fix the parapet wall. This means that in the above structure, if an internal gutter drainage system is used to drain roof water, an irregularly shaped gutter is required.

[0004] In the process of realizing this utility model, the inventors discovered that the prior art has at least the following problems:

[0005] Irregularly shaped gutters present numerous leakage points during use. Due to their multiple bends, water flow at the outer edges of these bends is typically faster than at the inner edges, causing water to overflow and seep into the factory building through the walls. This problem becomes particularly pronounced with increasing drainage volume. Furthermore, the manufacturing difficulty of irregularly shaped gutters also leads to higher project costs. Utility Model Content

[0006] The purpose of this invention is to provide a waterproof sealing system for the gaps between gutters and parapet walls to solve the above-mentioned problems.

[0007] To achieve this objective, on the one hand, a waterproof sealing system for the gap between the gutter and the parapet wall is provided. The adjacent parapet walls are connected by fixed columns, and the gutter is located between the parapet wall and the roof truss. A first water-blocking structure is provided between the adjacent fixed columns. The first water-blocking structure is elongated, with one side connected to the parapet wall and the other side extending into the gutter. The first water-blocking structure covers the gap between the gutter and the parapet wall and is used to introduce fluid into the gutter.

[0008] Furthermore, the fixed column is provided with a second water-blocking structure. One side of the second water-blocking structure is fixedly connected to the surface of the fixed column near the gutter, and the other side of the second water-blocking structure extends into the gutter. The two ends of the second water-blocking structure are respectively spliced ​​or overlapped with the end portions of the adjacent first water-blocking structure.

[0009] Furthermore, a flashing plate is provided, which covers the first water-blocking structure and / or the flashing plate covers the second water-blocking structure.

[0010] Furthermore, a compacted filling structure is provided between the gutter and the parapet wall, and the compacted filling structure is located on the lower side of the first water-blocking structure.

[0011] Furthermore, it also includes a gutter base plate, one end of which is fixed to the parapet wall, and the gutter base plate is used to support the compacted filling structure.

[0012] Furthermore, the first water-blocking structure includes a first bend that extends into the gutter.

[0013] Furthermore, the second water-blocking structure includes a second bend that extends into the gutter.

[0014] Furthermore, the two ends of the second water-blocking structure are respectively fixedly connected to the adjacent first water-blocking structure.

[0015] Furthermore, the side wall of the fixed column is provided with a connecting plate, and the two ends of the first water-blocking structure are respectively connected to the plate surface of the connecting plate of the adjacent fixed column.

[0016] Furthermore, the two side walls of the fixed column are provided with connecting plates, and the side of the second water-blocking structure is fixedly connected to the end of the two connecting plates.

[0017] One of the above technical solutions has the following advantages or beneficial effects:

[0018] The gutter-parapet wall gap waterproofing and sealing system includes a first water-retaining structure. One side of the first water-retaining structure connects to the parapet wall, while the other side extends into the gutter. The first water-retaining structure completely covers the gap between the gutter and the parapet wall. In extreme weather conditions such as rain or snow, rainwater is directly guided into the gutter through the first water-retaining structure and discharged through the gutter's drain pipe. By employing this gutter-parapet wall gap waterproofing and sealing system, in building structures where adjacent parapet walls are fixedly connected by fixed columns, the gutter structure does not need to be irregularly shaped; a straight gutter can be used, which offers the advantage of unobstructed drainage. Therefore, this gutter-parapet wall gap waterproofing and sealing system has the advantages of fewer leakage points, good flow guidance performance, and unobstructed drainage.

Detailed Implementation

[0024] To make the technical problems solved by this utility model, the technical solutions adopted, and the technical effects achieved clearer, the technical solutions of the embodiments of this utility model will be further described in detail below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model. It should be noted that, in the absence of conflict, the following embodiments and features in the embodiments can be combined with each other.

[0025] like Figure 4 As shown, when the parapet wall 11 needs to be designed to be relatively high, adjacent parapet walls 11 are connected by fixed columns 12, which helps to improve the overall stability and seismic performance of the factory building. Furthermore, relevant specifications require that when the parapet wall needs to be designed to be relatively high, the thickness dimension of the cross-section of the fixed column connecting adjacent parapet walls must be greater than the thickness of the parapet wall. In this case, the location for the drainage gutter between the roof truss structure and the parapet wall structure is not a straight line viewed longitudinally, but rather a bend protruding towards the roof truss at the fixed column of the adjacent parapet wall. Generally, the number of bends is consistent with the number of fixed columns used to fix the parapet wall.

[0026] Currently, in the aforementioned structure, if an internal gutter drainage system is used to drain roof water, a 25mm irregularly shaped gutter is required. However, irregularly shaped gutters not only have high construction costs but also present numerous leakage points during use. Because irregularly shaped gutters have multiple bends, the water flow velocity on the outer side of the bend is typically faster than on the inner side. This causes water at the bends to overflow the gutter, seeping into the factory building through the walls. This problem becomes particularly pronounced as the drainage volume increases.

[0027] To solve the above problems, such as Figures 1-3 As shown, this embodiment provides a waterproof sealing system for the gap between gutters and parapet walls, which can be used in the waterproofing structure of frame structures commonly used in industrial plants. The frame structure includes a roof truss 14, which supports the roof 13. The roof 13 can be made of any existing form and material. The roof 13 and the roof truss 14 can be connected and fixed using a purlin system or a purlin-less system. Figure 1 This diagram illustrates a purlin-based connection and fixation method between the roof panel 13 and the roof truss 14. The purlins are connected to the upper chord of the roof truss 14 via purlin brackets 15. The purlin brackets 15 are made of short angle steel and welded to the upper chord of the roof truss 14. After the roof truss 14 is hoisted into place, it is connected to the purlins using bolts or welds. The roof panel 13 and the purlins can be connected using self-tapping screws with rubber washers, or by means of tile hooks, through nails, or tile nails.

[0028] like Figures 1-2The gutter and parapet wall gap waterproof sealing system provided in this embodiment is used when there are multiple parapet walls 11 and adjacent parapet walls 11 are connected by fixed columns 12. The gutter 20 is located between the parapet wall 11 and the roof truss 14. The gutter 20 has a shape similar to the English letter "U". When viewed vertically, its cross-section is a concave structure with an open top and a closed bottom. This shape allows it to effectively collect and transport rainwater and other liquids. The bottom of the gutter 20 is connected to the drain pipe 24. The bottom of the gutter 20 has a gutter base plate 23 and a gutter bracket 22. To increase the strength of the gutter 20, there are gutter reinforcing ribs 21 inside the gutter 20. The two ends of the gutter reinforcing ribs 21 are connected to the inner sidewall of the gutter 20.

[0029] like Figure 1 A flange 201 is provided at the opening end of the gutter 20 near the roof truss 14, and the top end of the gutter 20 is fixed to the lower side of the roof 13 by the flange 201. Optionally, the gutter 20 is fixed to the roof 13 by bolts, with the bolts passing under the roof 13 panel to fix the flange 201 of the gutter 20 to the roof 13 panel. There is a gap between the gutter 20 and the parapet wall 11 on the side near the parapet wall 11.

[0030] like Figures 1-3 A first water-blocking structure 31 is provided between adjacent fixed columns 12. The first water-blocking structure 31 is elongated, with one side connected to the parapet wall 11 and the other side extending into the gutter 20. The first water-blocking structure 31 covers the gap between the gutter 20 and the parapet wall 11, and is used to introduce fluid into the gutter. In this embodiment, the gutter and parapet wall gap waterproof sealing system includes a first water-blocking structure 31, which is elongated. Its end portions refer to the two extreme portions along its length, and its sides refer to the portions along both sides along the length of the object, located between the two end portions. The first water-blocking structure 31 is positioned between the fixed columns at both ends of the parapet wall, with each end connected to the sidewall of its adjacent fixed column. One side (i.e., one side portion) of the first water-blocking structure 31 is connected to the parapet wall 11, and the other side (i.e., the other side portion) extends into the gutter 20. The first water-blocking structure 31 completely covers the gap between the gutter 20 and the parapet wall 11. The side of the gutter 20 closest to the parapet wall 11 can be tightly attached to the fixed post 12. In this case, the gap between the gutter 20 and the parapet wall 11 is blocked and sealed by the first water-blocking structure 31. When drainage is needed in extreme weather such as rain or snow, rainwater is directly guided into the gutter 20 through the first water-blocking structure 31 and discharged through the drain pipe 24 of the gutter 20.

[0031] By employing the gutter and parapet wall gap waterproofing sealing system of this embodiment, a first water-blocking structure 31 is provided in the building structure where adjacent parapet walls 11 are fixedly connected by fixed columns 12. At this time, the gutter 20 does not need to be an irregularly shaped gutter 25, and a straight gutter 20 can be used. The straight gutter 20 has the advantage of smooth drainage. Thus, the building waterproofing structure using the gutter and parapet wall gap waterproofing sealing system of this embodiment has the advantages of fewer leakage points, good flow conduction performance, and smooth drainage.

[0032] Furthermore, such as Figures 1-3 A second water-blocking structure 32 is provided on the fixed column 12. One side of the second water-blocking structure 32 is fixedly connected to the surface of the fixed column 12 near the gutter 20, and the two ends of the second water-blocking structure 32 are respectively fixedly connected to the adjacent first water-blocking structure 31. There are multiple fixed columns 12 in the factory, and it is difficult to ensure that all fixed columns 12 can be connected to the side surface of the straight gutter 20. In order to solve the above problem, this embodiment also provides a second water-blocking structure 32. The second water-blocking structure 32 is also strip-shaped. The end portion of the second water-blocking structure 32 refers to the two extreme portions in its length direction, and the side portion refers to the two sides along the length direction of the object, which is located between the two end portions. One side of the second water-blocking structure 32 is fixedly connected to the surface of the fixed column 12 near the gutter 20, and the other side of the second water-blocking structure 32 extends into the gutter 20. The two ends of the second water-blocking structure 32 are respectively spliced ​​or overlapped with the end portions of the adjacent first water-blocking structure 31. The width of the second water-retaining structure 32 is referenced to the width of the fixed column. Generally, the width of the second water-retaining structure 32 is the same as the width of the fixed column. In the waterproof sealing system for the gap between the gutter and the parapet wall in this embodiment, the second water-retaining structure 32 is used to cover the gap between the fixed column 12 and the gutter 20. After the two ends of the second water-retaining structure 32 are spliced ​​or overlapped with the ends of the adjacent first water-retaining structure 31, all gaps between the gutter 20 and the parapet wall 11 are covered.

[0033] Furthermore, such as Figures 1-3The first water-retaining structure 31 includes a first bend 311, which extends into the gutter 20. Optionally, the first water-retaining structure 31 is made of metal materials, such as steel, aluminum, or other common building materials. Preferably, the first water-retaining structure 31 uses a continuous angle steel, which is a long, straight steel bar with an L-shaped cross-section, commonly used in the construction industry. The L-shaped cross-section of the continuous angle steel can serve as the first bend 311 of the first water-retaining structure 31. When using a continuous angle steel, its corners face upwards, so that one side of the continuous angle steel extends into the gutter 20. Further, in this embodiment, the continuous angle steel is an unequal-sided angle steel. An unequal-sided angle steel refers to angle steel with two sides of unequal width. For example, currently, angle steel specifications are expressed in millimeters as side width × side width × side thickness. 30mm × 20mm × 4mm indicates an unequal-sided angle steel with side widths of 30mm and 20mm and a side thickness of 4mm. The side with a width of 30mm is the wide side, and the side with a width of 20mm is the narrow side. Preferably, when the continuous angle steel in this embodiment is an unequal-sided continuous angle steel, it has one wide side and one narrow side. In this case, one side of the wide side connects to the parapet wall 11, and one side of the narrow side extends into the gutter 20. Unequal-sided continuous angle steel is a commonly used component in building structures, possessing strong stability and load-bearing capacity. In this embodiment, when the first water-retaining structure 31 uses unequal-sided continuous angle steel, it not only has the advantages of structural stability and reliability but also the advantages of readily available materials and low cost, making it suitable for large-scale use.

[0034] Furthermore, the connection between one side of the first water-blocking structure 31 and the parapet wall 11 is as follows: the one side of the first water-blocking structure 31 and the parapet wall 11 are sealed together with sealant. Optionally, the sealant is a weather-resistant structural adhesive.

[0035] Optionally, the parapet wall 11 in this embodiment can be a reinforced concrete structure, and the fixing column 12 connecting the two sets of parapet walls 11 is also a reinforced concrete column. Optionally, the parapet wall 11 in this embodiment can be a steel structure, such as the color steel plate commonly used in building structures, and the fixing column 12 connecting the two sets of parapet walls 11 can be a steel column.

[0036] Furthermore, such as Figure 2 A connecting plate 36 is provided on the side wall of the fixed column 12, and the two ends of the first water-blocking structure 31 are respectively connected to the plate surface of the connecting plate 36 adjacent to the fixed column 12. The connecting plate 36 is used to fix the first water-blocking structure 31. In use, when the first water-blocking structure 31 is made of metal, the ends of the first water-blocking structure 31 are welded to the connecting plate 36. When the first water-blocking structure 31 is made of other materials, appropriate fixing and connection processes can be adopted.

[0037] Optionally, when the fixed column 12 is a reinforced concrete column, the connecting plate 36 can be an embedded plate. That is, an embedded plate is installed on each side of the fixed column 12 connecting to the parapet wall 11, and the embedded plate is fixed to the side surface of the fixed column 12 by anchors 37. Optionally, when the fixed column 12 is a steel column, the connecting plate 36 can be a steel plate, and the connecting plate 36 can be welded to the steel column, or it can be fixedly connected by anchors 37.

[0038] Furthermore, such as Figure 2 The second water-retaining structure 32 includes a second bend 321 that extends into the gutter 20. Optionally, the second water-retaining structure 32 is made of metal materials, such as steel, aluminum, or other common building materials. Preferably, the second water-retaining structure 32 uses short angle steel, which is a long, straight steel bar with an L-shaped cross-section, commonly used in the construction industry. The L-shaped cross-section of the short angle steel can serve as the second bend 321 of the second water-retaining structure 32. When using short angle steel in the second water-retaining structure 32, its corners face upwards, so that one side of the short angle steel extends into the gutter 20. Further, the second water-retaining structure 32 can use equilateral angle steel, which refers to angle steel with two sides of equal width. In this embodiment, the width to be blocked by the second water-retaining structure 32 is smaller than that of the first water-retaining structure 31, and the use of angle steel has the advantages of good structural stability and low cost. Optionally, the second water-retaining structure 32 can also use unequal angle steel.

[0039] Furthermore, such as Figure 3 The two ends of the second water-blocking structure 32 are fixedly connected to the adjacent first water-blocking structure 31. The connection between the two ends of the second water-blocking structure 32 and the adjacent first water-blocking structures 31 on both sides can be splicing, overlapping, or butt jointing. After splicing, overlapping, or butt jointing, the two ends of the second water-blocking structure 32 are fixedly connected to the two ends of the first water-blocking structure 31. Optionally, when the second water-blocking structure 32 is made of short angle steel and the first water-blocking structure 31 is made of continuous angle steel, the two ends of the second angle steel are butt jointed with the adjacent continuous angle steel and then welded. Optionally, overlapping portions are cut out at the two ends of the second water-blocking structure 32. When the second water-blocking structure 32 is made of short angle steel and the first water-blocking structure 31 is made of continuous angle steel, the overlapping portions of the second water-blocking structure 32 are welded to the top of the first water-blocking structure 31.

[0040] Furthermore, the connection between one side of the second water-blocking structure 32 and the fixed column 12 is as follows: the one side of the second water-blocking structure 32 and the fixed column 12 are sealed together with sealant. Preferably, the sealant is a weather-resistant structural adhesive.

[0041] Furthermore, another method for connecting one side of the second water-blocking structure 32 to the fixed column 12 is as follows: the end portions of the connecting plates 36 on both sides of the fixed column are extended to the junction with the surface of the fixed column 12 near the gutter, and the side of the second water-blocking structure 32 is fixedly connected to the end portions of the connecting plates 36 on both sides of the fixed column. Since the length of the second water-blocking structure 32 is basically the same as the width of the surface of the fixed column near the gutter, the length of the second water-blocking structure 32 is relatively short, and the second water-blocking structure 32 can be securely fixed by a wire connection. When the second water-blocking structure 32 is a short angle steel, the second water-blocking structure 32 can be welded to the end portions of the two connecting plates.

[0042] Furthermore, such as Figure 2 Because the gap between the gutter 20 and the parapet wall 11 on the lower side of the first water-retaining structure 31 is relatively large, a filling and sealing structure 34 can be provided between the gutter 20 and the parapet wall 11. The filling and sealing structure 34 is located on the lower side of the first water-retaining structure 31. The filling and sealing structure 34 is used for thermal insulation to prevent thermal bridging of the entire house. Preferably, the material of the filling and sealing structure 34 is lightweight glass wool.

[0043] Furthermore, such as Figure 2 A compacted filling structure 34 can also be provided between the gutter 20 on the lower side of the first water-blocking structure 31 and the fixed column 12.

[0044] Furthermore, such as Figures 1-2 In this embodiment, the waterproof sealing system for the gap between the gutter and the parapet wall is equipped with a flashing 33, which covers the first water-blocking structure 31 and / or the second water-blocking structure 32. The flashing 33 is a waterproof component used in building roofs and other similar areas. It typically has a certain slope to guide rainwater to drain smoothly in a predetermined direction, preventing water accumulation and leakage or other structural problems. The flashing 33 is fixed to the structure by expansion bolts 38. A waterproof gasket 35 is provided between the flashing 33 and the expansion bolts 38 to guide water flow towards the flashing 33.

[0045] When encountering snow accumulation and melting, or heavy rainfall, the aforementioned flashing 33 exhibits numerous leakage points, with leaks particularly prone to occur at the expansion bolt openings and the connection points between the flashing 33 and the structure. In this embodiment, the waterproof sealing system for the gap between the gutter and the parapet wall involves installing a flashing 33 above the first water-retaining structure 31, with the flashing 33 covering the first water-retaining structure 31. Furthermore, a flashing 33 is installed above the second water-retaining structure 32, with the flashing 33 covering the second water-retaining structure 32.

[0046] Therefore, the waterproof sealing system for the gap between the gutter and the parapet wall in this embodiment uses a flashing as the first waterproof water-diverting structure, a first water-blocking structure as the second waterproof water-diverting structure, and / or a second water-blocking structure as the second waterproof water-diverting structure. This can effectively prevent roof leakage, seal the large gap between the wall and the gutter, and ensure that the gutter 20 is a straight, continuous gutter 20, thus guaranteeing the drainage performance of the gutter.

For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0048] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature.
