Description

Technical Field

[0001] The invention relates to the technical field of building construction, in particular to a canopy external eaves gutter connecting device and a construction method thereof. Background Art

[0002] As an essential component of a building's ancillary structures, the drainage design and construction quality of a canopy are directly related to the building's safety and durability. External gutters, a common drainage component for canopies, are primarily used to collect and drain rainwater from the roof, preventing it from directly impacting walls or the ground, thereby effectively reducing the risk of rainwater erosion on the building structure and surrounding environment.

[0003] At present, during the construction of external eaves gutters for canopies, traditional methods such as angle steel welding or bolt connection are often used to fix the eaves gutters to the canopy structure. However, these existing connection methods generally have certain limitations in practical applications. For example, if the welding is deformed or the connector is loose, it is very easy to cause insufficient fit between the gutter and the canopy, that is, the stability of the connection between the two cannot meet actual needs. At the same time, due to the lack of a stable connection or effective support between the gutter and the canopy, it will be displaced or sunken due to wind loads or vibrations during use, resulting in the destruction of the originally set drainage slope and reduced drainage efficiency. In severe cases, it may even cause safety hazards such as water accumulation, overflow or gutter detachment. Summary of the Invention

[0030] See also Figures 1 to 3 , Figure 1 A schematic diagram of the structure of a canopy external gutter connection device provided by an embodiment of the present invention; Figure 2 A schematic diagram of the structure of the gutter body and the bracket keel in the canopy external gutter connection device provided by an embodiment of the present invention; Figure 3 A schematic flow chart of a construction method for a canopy external gutter connection device provided in an embodiment of the present invention.

[0031] See again Figures 1 to 2 The embodiment of the present invention provides an external gutter connection device for a canopy, comprising a canopy body 100, a gutter body 200, and a bracket keel 300; the bottom of the bracket keel 300 is connected to the lower part of the canopy body 100; the canopy body 100 comprises a main keel 110, a secondary keel 120 and a purlin 130, the main keel 110 being connected in parallel to the upper part of the secondary keel 120 through the purlin 130; the bracket keel 300 is stepped, and the step plane of the bracket keel 300 overlaps with the extension direction of the secondary keel 120; the space formed between the main keel 110, the purlin 130, the secondary keel 120 and the bracket keel 300 is a first space, and the gutter body 200 is arranged in the first space, and is connected to the purlin 130 and the bracket keel 300.

[0032] In this embodiment, unlike the conventional method of directly fixing the gutter to the canopy with rivets, a stepped bracket keel 300 is initially fixed to the lower portion of the canopy body 100. The mounting position of the bracket keel 300 is then adjusted so that the stepped plane of the bracket keel 300 is flush with or overlaps the length extension direction of the secondary keel 120 of the canopy body 100. Based on the structural characteristics between the canopy body 100 and the stepped bracket keel 300, a first space for mounting the gutter body 200 is formed. Finally, the gutter body 200 is prefabricated according to the length and height of the first space and positioned within the first space. The prefabricated gutter body 200 is then connected and fixed to the contact surface between the canopy body 100 and the bracket keel 300. Based on the above, a stable connection between the gutter body 200 and the canopy body 100 is achieved, and the problem of inaccurate drainage slope caused by a loose connection between the two is avoided.

[0033] Specifically, the canopy body 100 comprises a main purlin 110, a secondary purlin 120, and purlins 130. The purlins 130 are approximately Z-shaped, with the top of the purlins 130 connected and fixed to the main purlin 110 and the bottom of the purlins 130 connected and fixed to the secondary purlins 120. In other words, the main purlins 110 are connected parallel to the upper portion of the secondary purlins 120 via the purlins 130. The bracket purlin 300 is stepped, or in other words, N-shaped, with its center parallel to the horizontal plane, its top perpendicular to the right end of the center, and its bottom perpendicular to the left end of the center. This gives the bracket purlin 300 an overall stepped shape. The bottom of the bracket keel 300 is connected to the secondary keel 120 of the canopy body 100 (i.e., the bottom of the canopy body 100). The stepped surface of the bracket keel 300 is flush with or overlaps the extension direction of the secondary keel 120 of the canopy body 100. Thus, an installation space is formed between the main keel 110, purlin 130, secondary keel 120, and bracket keel 300. This installation space is the first space and is used to install the gutter body 200. The gutter body 200 is placed in this installation space (i.e., the first space) and is connected and fixed to the contact surface between the canopy body 100 and the bracket keel 300. Since the gutter body 200 forms a single fixation with the canopy body 100, the gutter body 200 forms a double fixation with the bracket keel 300, and the bracket keel 300 forms a triple fixation with the canopy, it is equivalent to fixing the gutter body 200 on the canopy body 100 by triple fixation. In this way, the connection between the gutter body 200 and the canopy body 100 is greatly strengthened, and the connection stability between the gutter body 200 and the canopy body 100 is improved.

[0034] It should be noted that the present application does not limit the installation order between the canopy body 100, the gutter body 200 and the bracket keel 300. The installation order between the canopy body 100, the gutter body 200 and the bracket keel 300 can be selected according to actual construction requirements.

[0035] In one embodiment, if Figure 1 As shown, the secondary keel 120 includes a first keel 121 and a second keel 122; the first keel 121 is connected in parallel to the second keel 122, and the first keel 121 is located between the main keel 110 and the second keel 122; the first keel 121 is connected to the bottom of the main keel 110 through the purlin 130; the step plane of the bracket keel 300 overlaps with the extension direction of the first keel 121.

[0036] In this embodiment, the first keel 121 and the second keel 122 can be made of hot-dip galvanized steel (for example, Q235B), which has a moderate yield strength and good rust and corrosion resistance. It can not only effectively extend the service life of the canopy, but also adapt to different climatic environments. The main keel 110 can be made of low-alloy high-strength structural steel (for example, Q345B), which has high strength and can withstand greater loads, providing a stable support frame for the canopy. The bracket keel 300 can be made of steel with the same or similar strength as the main keel 110 (for example, Q345B steel) to ensure that it has sufficient bearing capacity and stability to support the eaves gutter body 200 and the additional loads that may be borne, while forming a coordinated force system with the main keel 110 and the secondary keel 120.

[0037] The main keel 110, the secondary keel 121, and the secondary keel 122 are parallel to each other. The upper surface of the primary keel 121 is connected to the lower surface of the main keel 110 via purlins 130, and the lower surface of the primary keel 121 is connected to the upper surface of the secondary keel 122 via steel beams 150, placing the primary keel 121 between the main keel 110 and the secondary keel 122. The stable connection between the primary keel 121, the secondary keel 122, and the main keel 110 forms a robust spatial truss structure. This system effectively distributes and transmits various loads borne by the canopy, including its own gravity, wind loads, snow loads, and additional loads generated by human activity. Through a reasonable mechanical transmission path, the main keel 110 can transfer the upper load to the primary keel 121 through the purlin 130. The primary keel 121 then disperses the load to the secondary keel 122 through the steel beam 150, and finally transfers all the loads safely to the main structure of the building, avoiding structural deformation or damage caused by local stress concentration. At the same time, the parallel arrangement and stable connection of the three enhances the rigidity and stability of the canopy structure in the horizontal and vertical directions, improves the wind and earthquake resistance of the structure, ensures the long-term safe and reliable operation of the canopy in complex environments, reduces structural maintenance costs, and extends its service life. In addition, this structural form also provides a stable installation foundation for the eaves gutter, bracket keel 300 and other components on the upper part of the canopy, facilitates the smooth progress of subsequent construction, and ensures the construction quality and usability of the entire canopy system.

[0038] The purlins 130 can be connected to the main purlins 110 and the secondary purlins 121 by bolts and / or welding. Similarly, the steel beams 150 can be connected to the primary purlins 121 and the secondary purlins 122 by bolts and / or welding. The specific connection method can be selected based on actual needs. By properly combining these two connection methods, construction costs and subsequent maintenance requirements can be optimized while ensuring structural safety.

[0039] Furthermore, when the stepped surface overlaps the extension direction of the primary keel 121, loads borne by the bracket keel 300 (such as the weight of accumulated gutter water and snow loads) can be directly transferred along the length of the primary keel 121, reducing the number of transitions in load transfer. For example, after the gutter body 200 is connected to the bracket keel 300 via the first vertical portion 310 and the horizontal portion 330, the load can be directly transferred to the primary keel 121 along the extension direction of the stepped surface. The load is then distributed to the main keel 110 and the secondary keel 122 via the purlins 130 and the steel beams 150, thus avoiding localized stress concentration. Furthermore, when the stepped surface of the bracket keel 300, used for mounting the gutter body 200, overlaps the extension direction of the primary keel 121, allowing the drainage direction of the gutter (the interior space of the gutter body 200 being the gutter) to align with the slope of the primary keel 121 (if the primary keel 121 has a drainage slope), ensuring that rainwater drains quickly along a linear path and avoiding the formation of water-logging grooves due to directional misalignment.

[0040] In one embodiment, if Figure 1 As shown, the canopy body 100 also includes a diagonal bracing keel 140 and a steel beam 150; the diagonal bracing keel 140 is located between the main keel 110 and the first keel 121, and its bottom is connected to the end face of the first keel 121 facing the main keel 110, and its side wall is connected to the middle part of the purlin 130; the top of the steel beam 150 is connected to the end face of the first keel 121 facing away from the main keel 110, and its bottom is connected to the second keel 122, and its middle is connected to the bottom of the bracket keel 300.

[0041] In this embodiment, the steel beam 150 can be hot-dip galvanized or sprayed with a high-performance anti-corrosion coating to extend its service life. The diagonal bracing keels 140 can be constructed from low-alloy, high-strength structural steel (e.g., Q345B) to ensure high strength and toughness to effectively withstand the various loads imposed on the canopy. Similarly, the diagonal bracing keels 140 can be hot-dip galvanized to enhance their corrosion resistance in outdoor environments.

[0042] At the end face of the primary keel 121 facing the main keel 110, a connecting steel plate can be welded to the primary keel 121 according to the installation angle and position of the diagonal keel 140. The connecting steel plate and the primary keel 121 can be fully welded to ensure a firm connection. Subsequently, the bottom of the diagonal keel 140 is connected to the connecting steel plate by high-strength bolts, thereby improving the connection reliability between the diagonal keel 140 and the primary keel 121. In the middle of the purlin 130, corresponding to the side wall position of the diagonal keel 140, a short angle steel connector can be welded. The side wall of the diagonal keel 140 is connected to the short angle steel connector by high-strength bolts. If necessary, spring washers can be installed to prevent loosening after the bolts are tightened to ensure the stability of the connection between the diagonal keel 140 and the purlin 130.

[0043] The setting of the diagonal bracing keel 140 forms a triangular support structure between the main keel 110 and the first keel 121. By utilizing the stability principle of the triangle, the stability of the canopy structure in the vertical and horizontal directions is effectively improved. When the canopy is subjected to wind loads, snow loads or other horizontal forces, the diagonal bracing keel 140 can quickly transfer the force to the first keel 121 and the purlin 130, and then transfer it to the main structure of the building through the main keel 110, reducing the deformation and shaking of the structure, thereby avoiding the subsequent displacement of the drainage slope of the gutter body 200 due to the deformation of the canopy body 100. In addition, the connection of the steel beam 150 further strengthens the connection between the first keel 121, the second keel 122 and the bracket keel 300, forming a complete spatial force system, so that the entire canopy structure can better resist various complex loads and provide a reliable structural foundation for the subsequent installation and fixation of the gutter body 200.

[0044] The steel beam 150 is a "C"-shaped steel beam 150. The top and bottom of the steel beam 150 are connected and fixed to the first keel 121 and the second keel 122 by welding. For the connection between the middle part of the steel beam 150 and the bracket keel 300, bolt connection or welding connection can be used. If bolt connection is used, the bolts should be installed according to the spacing and specifications required by the design, and ensure that the tightening torque of the bolts meets the requirements to prevent the eaves gutter from loosening. If welding is used, the welding quality must be guaranteed, and the welding parts should be firm and flat, without defects such as cold welds and leaking welds. After welding is completed, apply anti-rust paint to the welding parts, and spot weld the bracket and the eaves gutter to ensure that the eaves gutter will not slip.

[0045] In one embodiment, if Figure 2 As shown, the bracket keel 300 includes a first vertical portion 310, a second vertical portion 320 and a horizontal portion 330; the first vertical portion 310 and the second vertical portion 320 are respectively vertically connected to the opposite side end surfaces of the horizontal portion 330, wherein the first vertical portion 310 is connected to the end surface of the horizontal portion 330 facing the main keel 110, and the second vertical portion 320 is connected to the end surface of the horizontal portion 330 facing away from the main keel 110; the plane where the horizontal portion 330 is located is the step plane of the bracket keel 300; the first vertical portion 310 and the horizontal portion 330 are connected to the eaves gutter body 200, and the second vertical portion 320 is connected to the middle part of the steel beam 150.

[0046] In this embodiment, the bracket keel 300 is composed of a first vertical portion 310, a second vertical portion 320, and a horizontal portion 330. Specifically, the first vertical portion 310 and the second vertical portion 320 are welded perpendicularly to opposite ends of the horizontal portion 330. The first vertical portion 310 is located on the end of the horizontal portion 330 facing the main keel 110, and the second vertical portion 320 is located on the end of the horizontal portion 330 facing away from the main keel 110. More specifically, the first vertical portion 310 is connected to the right end of the horizontal portion 330, and the second vertical portion 320 is connected to the left end of the horizontal portion 330. Based on the above, the bracket keel 300 is approximately N-shaped.

[0047] The first vertical portion 310 serves as a fixed fulcrum for the gutter body 200. It is welded or riveted to the gutter body 200 to ensure that the gutter body 200 can stably bear the rainwater load. The second vertical portion 320, serving as the bottom of the bracket keel 300, is bolted or welded to the middle of the steel beam 150 to enhance the overall rigidity of the bracket keel 300 and facilitate the transfer of the load from the gutter body 200 to the canopy body 100.

[0048] The plane of the horizontal portion 330 is parallel to the horizontal plane and corresponds to the stepped plane of the bracket keel 300. Furthermore, the plane of the horizontal portion 330 overlaps with the plane of the primary keel 121 in the canopy body 100. In other words, the horizontal portion 330 and the primary keel 121 overlap along their respective lengths. Together, the horizontal portion 330 and the primary keel 121 serve as a platform for setting the drainage slope of the gutter body 200.

[0049] Furthermore, to ensure structural stability and durability, all joints on the bracket keel 300 are fully welded or bolted, and the welds are coated with anti-rust paint. Besides being made from custom stainless steel, the bracket keel 300 can also be made from cold-formed galvanized channel steel, which also offers both strength and corrosion resistance.

[0050] In one embodiment, if Figure 1 as well as Figure 2 As shown, it also includes a connecting component 400; the gutter body 200 is connected to the purlin 130 through the connecting component 400; the connecting component 400 includes a pull rod 410 and a first connecting member 420, the gutter body 200 is connected to the purlin 130 through the first connecting member 420, and the first connecting member 420 is connected to the top of the gutter body 200.

[0051] Specifically, the gutter body 200 includes a first steel plate 210, a second steel plate 220, and a third steel plate 230; the first steel plate 210 and the third steel plate 230 are respectively vertically connected to the opposite side ends of the end face of the second steel plate 220 facing the main keel 110; the first steel plate 210 is connected to the purlin 130 through the first connecting member 420; the second steel plate 220 is connected to the secondary keel 120 and the step plane of the bracket keel 300, and the third steel plate 230 is connected to the bracket keel 300; the two ends of the pull rod 410 are respectively connected to the first steel plate 210 and the third steel plate 230.

[0052] In this embodiment, the gutter body 200 is enclosed by a first steel plate 210, a second steel plate 220, and a third steel plate 230, forming an open rectangular structure. The first and third steel plates 210, 230 are respectively connected perpendicularly to the end surface of the second steel plate 220 facing the main keel 110, and are located on the left and right ends of the second steel plate 220. The opposite ends of the tie rod 410 are welded to the top of the first and third steel plates 210, 230, respectively. The tie rod 410 is welded to the tops of the first and third steel plates 210, 230, forming a "top support beam" that connects the two steel plates and effectively compensates for the stiffness loss caused by the top opening of the rectangular structure. For example, when the gutter is subjected to wind loads or vibration, the tie rod 410 can limit the lateral displacement of the two steel plates, preventing the reduction in cross-sectional stiffness caused by the top opening. This effectively adds a tensile and compressive "chord" at the opening, improving overall bending stiffness.

[0053] The first steel plate 210, the second steel plate 220, and the third steel plate 230 can be made of stainless steel. The stainless steel plates are pressed according to predetermined dimensions to form the gutter body 200. The interior space of the gutter body 200 serves as the drainage gutter. The distance between the purlin 130 and the first vertical portion 310 of the bracket keel 300 is in a 1:1 ratio with the length of the second steel plate 220. This allows the gutter body 200 to fit within the first space. Furthermore, when the bottom of the bracket keel 300 is connected and secured to the canopy body 100, it provides support for the gutter body 200 toward the canopy body 100, thereby enhancing the stability of the connection between the gutter body 200 and the canopy body 100.

[0054] The first connecting member 420 may be a rivet, and the number of rivets is set according to actual needs. The function of the first connecting member 420 is to connect the gutter body 200 and the canopy body 100.

[0055] After the gutter body 200 fits within the first space, its outer walls are connected to the canopy body 100 and the bracket keel 300, respectively. Specifically, the first steel plate 210 in the gutter body 200 is connected to the purlin 130 in the canopy body 100 via a first connector 420. Because the stepped plane of the bracket keel 300 is flush with or overlaps the length of the primary keel 121, the second steel plate 220 is connected to the stepped plane between the primary keel 121 and the bracket keel 300 (i.e., the horizontal portion 330 of the bracket keel 300). The third steel plate 230 is perpendicular to the right end of the second steel plate 220, and the top of the bracket keel 300 (i.e., the first vertical portion 310) is perpendicular to its stepped plane, thus connecting the third steel plate 230 to the top of the bracket keel 300. The design of multi-point connection and coordinated force distribution disperses the stress on the gutter body 200 during long-term use, reduces the risk of the drainage slope of the gutter body 200 being offset, and improves the accuracy of the drainage slope.

[0056] In addition, sealant is used to seal the connection between the gutter body 200 and the canopy body 100, as well as the connection points between the first steel plate 210, the second steel plate 220, and the third steel plate 230 in the gutter body 200. Before applying the sealant, clean any debris and dust from the surface of the connection points to ensure a tight bond between the sealant and the contact surface. Apply the sealant evenly and fully, avoiding gaps or bubbles to prevent rainwater leakage.

[0057] In one embodiment, if Figure 1 as well as Figure 2 As shown, the canopy further includes a support assembly 500; the support assembly 500 is connected to the end surface of the bracket keel 300 facing away from the canopy body 100. Specifically, the support assembly 500 includes a color steel plate outer component 510 and a second connecting component 520; the color steel plate outer component 510 is connected to the end surface of the bracket keel 300 facing away from the canopy body 100 via the second connecting component 520.

[0058] In this embodiment, the color-coated steel plate outer covering 510 is secured to the outer surface of the bracket keel 300 via a second connector 520. The outer surface of the bracket keel 300 is also the end surface of the bracket keel 300 facing away from the canopy body 100. The color-coated steel plate covering the outer surface of the bracket keel 300 effectively blocks rainwater, ultraviolet rays, and pollutants from directly contacting the structure, extending the life of the keel structure and improving overall protective performance. The thickness of the color-coated steel plate outer covering 510 (e.g., 1.5 mm) should be selected based on actual construction needs. The second connector 520 can be a high-strength bolt.

[0059] Specifically, the color steel plate outer casing 510 includes a first outer casing, a second outer casing, and a third outer casing. The first outer casing is disposed on the outer surface of the first vertical portion 310, the second outer casing is disposed on the end surface of the horizontal portion 330 facing away from the main keel 110, and the third outer casing is disposed on the outer surface of the second vertical portion 320. Each outer casing is connected to each component of the bracket keel 300 via a second connector 520. On the one hand, the use of connectors facilitates quick disassembly and replacement of the color steel plate outer casing 510 in the event of damage, deformation, or corrosion, reducing maintenance difficulty and subsequent operation and maintenance costs. On the other hand, the connector connection ensures the reliability of the connection between the color steel plate outer casing 510 and the bracket keel 300, effectively resisting high-altitude wind pressure and structural vibration, and extending the service life of the external gutter device.

[0060] In addition, in addition to being connected by connecting pieces, the outer color steel plate outer covering 510 and the bracket keel 300 can also be connected by welding, or by a combination of welding and connecting pieces, which can be specifically designed according to actual construction needs.

[0061] It should be noted that if a connection method using connectors is adopted, sealant needs to be applied to each connection between the connector and the color steel plate outer cover 510 to prevent rainwater from seeping into the fixing holes.

[0062] In one embodiment, if Figure 1 As shown, it also includes a drainage pipe 600; a first drainage outlet is provided at the bottom of the gutter body 200, and a second drainage outlet is provided on the step plane of the bracket keel 300. The first drainage outlet is aligned with the second drainage outlet to form a drainage channel, and the top of the drainage pipe is adapted to the drainage channel.

[0063] In this embodiment, a primary drain outlet (not shown) is located at the bottom of the gutter body 200 and serves as the primary outlet for collected rainwater. This outlet is typically a pre-reserved circular hole or rectangular slot, the dimensions of which can be determined based on flow rate calculations. If necessary, ribs or flanges can be added around the drain outlet to enhance structural strength.

[0064] A second drain outlet (not shown) is located on the stepped surface of the bracket keel 300, also known as the horizontal portion 330 of the bracket keel 300. This second drain outlet aligns with the first drain outlet, forming a vertically continuous drainage channel. This second drain outlet can be fabricated during the prefabrication phase of the bracket keel 300, facilitating rapid on-site positioning.

[0065] The first and second drain outlets are aligned to form a vertical drainage channel. If necessary, seals or flanges can be used to enhance the transition seal and prevent water seepage. The corresponding placement of the first and second drain outlets ensures that accumulated water in the gutter can be quickly drained, preventing water from accumulating at the end of the gutter and effectively preventing rainwater backflow and structural corrosion.

[0066] The top of the drainpipe connects to the bottom of the drainage channel, forming a closed drainage system. The drainpipe can be made of corrosion-resistant PVC, stainless steel, or aluminum alloy. Depending on the building structure, the lower portion of the drainpipe can be connected to a rainwater riser, floor drain, or water storage facility.

[0067] like Figure 3 As shown, an embodiment of the present invention further provides a construction method for a canopy external gutter connection device, which is applied to the canopy external gutter connection device in any of the aforementioned embodiments, and the method includes:

[0068] S1. Hoist the bracket keel and adjust its position so that the step plane of the bracket keel overlaps with the extension direction of the secondary keel of the awning body, and fix the bottom of the bracket keel to the lower part of the awning body.

[0069] In this embodiment, before hoisting, the specifications, models, and appearance quality of the prefabricated bracket keel 300 are fully inspected to ensure that there are no defects such as deformation and cracks. A marking tool (for example, a total station) is used to mark the installation position of the bottom of the bracket keel 300 (the bottom of the bracket keel 300 is also the second vertical portion 320) on the lower part of the canopy body 100. Strict inspection and precise measurement and positioning ensure the accuracy of the installation of the bracket keel 300, providing a reliable benchmark for the subsequent installation of the gutter body 200, avoiding the installation of the gutter due to the position deviation of the bracket keel 300, and reducing rework costs.

[0070] Subsequently, the bracket keel 300 is hoisted using a tower crane and specialized lifting rigging. After being hoisted to the vicinity of the installation location, it is slowly lowered. By adjusting the height and horizontal position of the tower crane hook and using tools to fine-tune the angle of the bracket keel 300, the stepped surface of the bracket keel 300 precisely overlaps with the extension direction of the primary keel 121 of the canopy body 100. This standardized hoisting and adjustment process ensures that the bracket keel 300 does not deform during installation, maintaining its structural integrity and load-bearing capacity.

[0071] After the bracket keel 300 is adjusted into position, it is fixed at the connection between its bottom and the lower part of the canopy body 100 by welding or bolting. If welding is used, first embed a steel plate in the lower part of the canopy body 100, and fully weld the bottom of the bracket keel 300 to the embedded steel plate. After welding, perform an appearance inspection and ultrasonic flaw detection on the weld. If bolt connection is used, use high-strength bolts and install spring washers to prevent loosening. After fixing, use a total station to check the position and verticality of the bracket keel 300 again to ensure that it meets the design requirements. A variety of reliable fixing methods and strict quality inspections ensure that the bracket keel 300 is firmly connected to the canopy body 100, which can effectively withstand the eaves gutter and other loads, and enhance the stability and safety of the overall structure of the canopy.

[0072] S2. Measure the first space formed between the canopy body and the bracket keel to obtain measurement data, and process the gutter material according to the measurement data to form the gutter body.

[0073] In this embodiment, a high-precision measurement tool (e.g., a laser rangefinder or total station) is used to perform three-dimensional measurements of the first space formed between the canopy body 100 and the bracket keel 300. The measurements include parameters such as the length, width, and height of the space, as well as the verticality and horizontality of each side. This high-precision measurement provides accurate spatial data, providing a reliable basis for the customized processing of the gutter body 200. This ensures a perfect fit between the gutter and the first space, avoiding installation difficulties and waterproofing issues caused by dimensional discrepancies.

[0074] Based on the measured data, combined with design requirements and drainage slope requirements, the gutter body 200 is further designed using professional architectural design software (e.g., AutoCAD, Revit), determining parameters such as gutter shape, size, and drainage direction. After the design is complete, technical personnel review the design drawings to ensure its rationality and feasibility. This professional design and review process ensures that the gutter design meets functional and structural safety requirements, optimizes drainage paths, and improves drainage efficiency.

[0075] The design drawings are submitted to the processing workshop, and gutter materials that meet quality standards (for example, stainless steel, aluminum alloy, etc.) are selected. A CNC plasma cutting machine is used to accurately cut the materials, and the cutting size error is controlled within ±1mm. After cutting is completed, the gutter material is bent, profiled, and processed using dedicated forming equipment to form the shape required by the design. During the processing, the edges of the gutter body 200 are polished to remove burrs and sharp corners to prevent scratches on construction workers and affect drainage. Advanced processing equipment and strict quality control ensure the processing accuracy and quality of the gutter body 200, giving it a good appearance and performance, extending its service life, and reducing quality risks during the construction process.

[0076] Install prefabricated tie rods 410 fixing accessories on the gutter, maintaining a spacing of 1500mm-2000mm. Tie rods 410 can be made of round steel covered with waterproof membrane, or stainless steel, with welds painted with waterproof paint. After accessory installation, conduct a comprehensive inspection of the gutter body 200, including dimensional accuracy, shape, and accessory installation security, to ensure compliance with design and usage requirements.

[0077] S3. Hoist the gutter body into the first space, and connect and fix the gutter body to the contact surface of the awning body and the bracket keel.

[0078] In this embodiment, a tower crane is used to lift the fabricated gutter body 200 into the first space. Anti-collision measures are implemented during the lifting process to prevent damage to the gutter body 200 from colliding with the canopy body 100 and the bracket keel 300. Once the gutter body 200 is in place, it is fine-tuned using tools (e.g., a jack) to ensure accurate alignment with the contact surfaces of the canopy body 100 and the bracket keel 300. Standardized lifting and fine-tuning ensure that the gutter body 200 is not damaged during installation and is accurately installed, improving installation efficiency and quality.

[0079] The first steel plate 210 in the gutter body 200 is connected to the purlin 130 in the canopy body 100 via a first connector 420 (e.g., high-strength bolts, welded steel plates, etc.). If bolting is used, bolt holes are opened in corresponding positions on the purlin 130 and the first steel plate 210, and high-strength bolts are used for connection. If welding is used, a connecting steel plate is welded to the purlin 130, and the first steel plate 210 and the connecting steel plate are fully welded together. The weld is then visually inspected. These diverse and reliable connection methods tightly connect the gutter body 200 to the canopy body 100 and the bracket keel 300, forming an integrated load-bearing system that effectively transfers load and enhances the stability and waterproof performance of the canopy structure.

[0080] Because the stepped surface of the bracket keel 300 is flush with or overlaps the length of the primary keel 121, the second steel plate 220 is secured to the primary keel 121 and the horizontal portion 330 of the bracket keel 300 via welding or bolting. During connection, ensure that the second steel plate 220 fits snugly against the primary keel 121 and the horizontal portion 330 of the bracket keel 300. If welding is used, the weld should be continuous and full. If bolting is used, the bolt spacing should be no greater than 200 mm, and the tightening torque should meet design requirements.

[0081] The third steel plate 230 is perpendicular to the right end of the second steel plate 220 and is connected to the top of the bracket keel 300 (the first vertical portion 310) by welding or bolts. Before connection, the connection parts are rust-removed and polished to ensure the quality of the connection. After the connection is completed, check the overall installation of the gutter body 200 to ensure that each connection part is firm and reliable without looseness or deformation. Strict connection quality inspection ensures the installation firmness of the gutter body 200, avoids problems such as leakage and falling off due to loose connections, and ensures the normal use and safety of the canopy.

[0082] In addition, sealant is used to seal the connection between the gutter body 200 and the canopy body 100, as well as all other connection points within the gutter body 200. Use a reliable, weather-resistant sealant. Before applying the sealant, clean any debris and dust from the connection areas to ensure a tight bond between the sealant and the contact surface. Apply the sealant evenly and fully, avoiding gaps or bubbles to prevent rainwater leakage. Meanwhile, the processed 1.5mm color-coated steel plate outer shell 510 is bolted to the bracket keel 300 to ensure a straight, smooth eaves and a flat surface.

[0083] S4. Calibrate the fixed position of the gutter body according to the drainage slope requirements, and conduct stability tests and drainage performance tests on the connection parts of the gutter body, canopy body and bracket keel.

[0084] In this embodiment, a level is used to calibrate the fixed position of the gutter body 200 according to the drainage slope required by the design. By adjusting the thickness of the gasket at the bottom of the gutter or the height of the support point, the drainage slope of the gutter meets the requirement of not less than 2%, ensuring smooth drainage. During the calibration process, the elevation of the gutter body 200 is measured at a certain interval (for example, every 2 meters) to ensure that the slope is uniform. Accurate drainage slope calibration ensures the normal drainage function of the gutter, avoids leakage and structural damage caused by rainwater accumulation, and protects the canopy and the main structure of the building.

[0085] At the same time, the drain outlet of the gutter body 200 is specially treated. Drain outlet accessories can be installed, and the connection between the drain outlet and the gutter body 200 is sealed with sealing materials to ensure smooth drainage and no leakage at the drain outlet.

[0086] Stability tests were conducted on the connections between the gutter body 200, the canopy body 100, and the bracket keel 300. Using a loading test method, simulated loads (e.g., sandbags, water bags, etc.) were gradually added to the gutter, with the load weight being 1.2 times the design load. The connections were continuously observed for deformation, looseness, cracks, and other signs. Strain gauges and other equipment were also used to monitor stress changes in key areas to ensure the safety of the structure under load.

[0087] Drainage performance testing is performed by injecting a large amount of water into the gutter body 200, simulating rainfall. The flow and drainage rate of rainwater within the gutter body 200 are observed, and any water accumulation within the gutter body 200 is checked. The connections between the gutter body 200, the canopy body 100, the bracket keel 300, and the drain outlet are also inspected for leaks. If any problems are found, adjustments and repairs are promptly made until the design requirements are met. Rigorous stability and drainage performance testing can promptly identify potential quality issues and safety hazards, allowing for proactive rectification and ensuring the safety and reliability of the canopy during use.

[0088] After the test is completed, the test data is collated and analyzed to produce a detailed test report. This report includes the test process, test results, identified issues, and solutions, providing a basis for project acceptance. This detailed test report provides a scientific and accurate basis for project acceptance and also serves as a reference for subsequent maintenance and management, helping to improve project quality and management.

In this embodiment, after the bracket keel 300 is connected and fixed to the canopy body 100, the gutter body 200 is arranged in the first space formed between the bracket keel 300 and the canopy body 100, and the gutter body 200 is connected and fixed to the canopy body 100 and the bracket keel 300 respectively, thereby improving the stability of the connection between the gutter body 200 and the canopy body 100 and the accuracy of the drainage slope.
