Description

Technical Field

[0001] This utility model belongs to the field of waterproof interlocking technology for color steel tiles, specifically relating to a waterproof interlocking structure for roof color steel tiles. Background Technology

[0002] Color-coated steel roofing sheets, also known as color-coated steel sheet profiled sheets, are products made by chemically treating cold-rolled steel sheets or hot-dip galvanized steel sheets, coating them with one or more layers of organic coating, and then baking and curing them. Depending on the inner layer material, color-coated steel roofing sheets can be divided into various types, such as polystyrene color-coated steel roofing sheets, fiberglass color-coated steel roofing sheets, and the innovative PE (polyethylene) color-coated steel roofing sheets.

[0003] Corrugated steel roofing sheets have a wide range of applications, covering industrial, civil, agricultural, and commercial sectors. In the industrial sector, their lightweight, high strength, easy installation, and maintenance make them an ideal choice for large-span buildings such as industrial plants, warehouses, and stadiums. In the civil sector, corrugated steel roofing sheets are increasingly used in villas, roof renovations, and balcony enclosures, enhancing both the overall aesthetics and thermal insulation performance of buildings. Furthermore, they are widely used in agricultural greenhouses, commercial districts, and municipal facilities.

[0004] However, when installing corrugated steel roofing sheets on long roof ridges, drainage and waterproofing must be fully considered. The current installation method of corrugated steel roofing sheets requires the application of sealant. Due to the long span of the roof, if any part is missing, it will lead to water leakage. Utility Model Content

[0005] To solve the above-mentioned technical problems, this utility model provides a waterproof fastening structure for roof color steel tiles. By forming an obtuse angle at one end of the abutment plate of the water guide channel, the connecting part on it can be fastened and abutted with the overlapping profiled plate. Then, by screwing in the screws, the overlapping part is pressed down onto the limiting plate for position fixation. Due to the angle setting, reverse seepage of rainwater can be avoided.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0007] A waterproof fastening structure for corrugated steel roofing sheets includes a top sealing component, a water guiding channel, and profiled sheets. The top sealing component is an inverted U-shaped structure formed by a top plate and two sets of side plates. The water guiding channel is a U-shaped structure formed by a fixing plate, a bottom plate, and an abutment plate. The angle between the bottom plate and the abutment plate is an obtuse angle. The fixing plate is detachably connected to the inner side of the side plates. The abutment plate has an outwardly extending connecting portion. The profiled sheets include two sets. The right end of the profiled sheet cross-section has an upwardly raised top connecting portion, which is an upwardly raised arc-shaped structure. The left end of the profiled sheet cross-section has an upwardly raised and outwardly extending overlapping portion, which is a downwardly bent arc-shaped structure. One set of profiled sheets is pressed onto the top connecting portion of the other set of profiled sheets through the overlapping portion to form a fastening assembly. The fastening assembly is detachably connected to the connecting portion. The overlapping portion is fastened to the top of the top connecting portion.

[0008] The connecting part has a 7-shaped structure with a cross-section formed by connecting a horizontal plate and a vertical plate. The vertical plate has a receiving slot, and the fastening assembly is fitted into the receiving slot and abuts against the abutment plate. The horizontal plate has a screw hole facing the receiving slot, and a stud is fitted into the screw hole. The end of the stud abuts against the overlapping part. The outer side wall of the abutment plate has a limiting plate, and the upper end of the limiting plate abuts against the bottom of the forming plate.

[0009] The waterproof interlocking structure of the roof corrugated steel sheet adopts this design. The inverted U-shaped top sealing component fits onto the ridge, and the downward-extending side plates are pressed onto the fixing plate of the water guide channel. The fixing plate is located on the inner side of the side plate and is locked in place by rivets or screws. The fixing plate, bottom plate, and abutment plate of the water guide channel are integrally formed into a trough structure, thus effectively absorbing water flow. The outward-extending connecting part on the abutment plate is a 7-shaped structure formed by connecting horizontal and vertical plates. The vertical plate has a accommodating... The slots are used to connect the fastening components, which abut against the abutment plate. To prevent rainwater from seeping out from the connection between the fastening components and the abutment plate during rain, the angle between the base plate and the abutment plate is set to an obtuse angle. Therefore, the upper part of the connection between the fastening components and the abutment plate is blocked by the horizontal plate, and the rainwater can be guided along the downward slope of the profiled plate. Therefore, even if no sealant is added to the abutment of the fastening components and the abutment plate, rainwater can be prevented from flowing in from there.

[0010] Since both the length of the water guide channel and the length of the profiled sheet are limited, when the length exceeds a certain limit, two sets of water guide channels need to be stacked and interlocked. Therefore, during the stacking process, the receiving slots on the two sets of water guide channels overlap, and sealant is applied to the overlapping area to prevent water seepage. The profiled sheet has an upward-curving arc-shaped top section on the right end of its cross-section and an upward-curving, outward-extending, downward-bending arc-shaped overlapping section on the left end of its cross-section. A set of profiled sheets is pressed together through the overlapping section. An overlapping connection is made on the top part of another set of forming plates to form a fastening assembly. The fastening assembly fits into the contour edge of the receiving slot and has a screw hole on the horizontal plate. The screw hole faces the overlapping part at the top of the fastening assembly in the receiving slot. The lower end of the forming plate abuts against the limiting plate on the outer wall of the abutment plate. Therefore, after the stud is screwed into the screw hole, the stud gradually pushes down and abuts against the overlapping part, pressing the entire fastening assembly down and against the limiting plate for limiting and fixing, thereby preventing the position of the forming plate from moving and ensuring that the fastening assembly on it can remain against the abutment plate.

[0011] Furthermore, the surface of the forming plate is provided with several upwardly protruding force-adding grooves.

[0012] Compared with the prior art, the advantages of this utility model are as follows: A top-joining part with an upward lifting structure is provided on the right end of the forming plate, and a stacking part with an upward lifting structure is provided on the left end of the forming plate. One set of forming plates is pressed onto the top-joining part of another set of forming plates through the stacking part to form an overlapping connection and a fastening assembly. This fastening assembly fits into the contour edge of the receiving slot, and is secured by screws in the screw holes on the horizontal plate, so that the downward-lifting screws abut against the stacking part, pressing the entire fastening assembly down and against the limiting plate for positioning and fixation. Because the upper end of the connection between the fastening assembly and the abutting plate is blocked by the horizontal plate, the rainwater received can be guided along the downward tilt of the forming plate. Therefore, even if no sealant is added to the abutting point between the fastening assembly and the abutting plate, rainwater can be prevented from flowing in from there. Attached Figure Description

The right end of the cross-section of the profiled sheet 3 is provided with an upwardly raised top joint 31, the top joint 31 being an upwardly raised arc-shaped structure. The left end of the cross-section of the profiled sheet 3 is provided with an upwardly raised and outwardly extended overlapping part 32, the overlapping part 32 being a downwardly bent arc-shaped structure. One set of profiled sheets 3 is pressed onto the top joint 31 of another set of profiled sheets 3 through the overlapping part 32 to form an overlapping connection and a fastening assembly 33. The fastening assembly 33 is detachably connected to the connecting part 231, and the overlapping part 32 is fastened to the top of the top joint 31.

[0021] The connecting part 231 has a 7-shaped structure in cross-section formed by connecting a horizontal plate 232 and a vertical plate 233. The vertical plate 233 is provided with a receiving slot 2331. The fastening component 33 is fitted and connected in the receiving slot 2331 and abuts against the abutting plate 23.

The upper end face of the limiting plate 234 abuts against the bottom of the forming plate 3.

[0022] Furthermore, the surface of the forming plate 3 is provided with several upwardly protruding force grooves 34.

[0023] Description of the working principle of this utility model:

[0024] The waterproof interlocking structure of the roof corrugated steel sheet adopts this structure. The inverted U-shaped top sealing piece 1 fits onto the ridge, and the downward-extending side plate 12 is pressed onto the fixing plate 21 of the water guide channel 2. That is, the fixing plate 21 is located on the inner side of the side plate 12, and it is locked and fixed by rivets or screws. The fixing plate 21, bottom plate 22 and abutment plate 23 of the water guide channel 2 are integrally formed channel-shaped structures, so they can effectively receive water flow. The outward-extending connecting part 231 on the abutment plate 23 is a 7-shaped structure formed by connecting the horizontal plate 232 and the vertical plate 233. The container on the vertical plate 233 The slot 2331 is used to connect the fastening component 33. The fastening component 33 abuts against the abutment plate 23. In order to prevent rainwater from seeping out from the connection between the fastening component 33 and the abutment plate 23 during rain, the angle between the base plate 22 and the abutment plate 23 is set to an obtuse angle. Therefore, the upper part of the connection between the fastening component 33 and the abutment plate 23 is blocked by the horizontal plate 232, and the rainwater received can be guided along the downward slope of the profiled plate 3. Therefore, even if no sealant is added to the abutment of the fastening component 33 and the abutment plate 23, rainwater can be prevented from flowing in from there.

[0025] Since the length of the water guide channel 2 and the length of the molding plate 3 are both limited, when the lengths are too long, two sets of water guide channels 2 need to be stacked and interlocked. Therefore, during the stacking process, the receiving slots 2331 on the two sets of water guide channels 2 overlap, and sealant is applied to the overlapping part of the two sets of water guide channels 2 to prevent water leakage. The molding plate 3 has an upward-curving arc-shaped top-fitting part 31 on the right end of its cross-section and an upward-curving and outwardly extending downward-bending arc-shaped overlapping part 32 on the left end of its cross-section. One set of molding plates 3 is pressed onto the top-fitting part 31 of the other set of molding plates 3 through the overlapping part 32 to form an interlocking assembly 33. This interlocking assembly 33 fits into the receiving slot 2. The outline edge of 331 is provided with screw holes 2321 on the horizontal plate 232. The screw holes 2321 face the overlapping part 32 on the top of the fastening component 33 in the receiving slot 2331. The lower end of the forming plate 3 abuts against the limiting plate 234 on the outer wall of the abutment plate 23. Therefore, after the stud is screwed into the screw hole 2321, the stud gradually pushes down and abuts against the overlapping part 32, pressing the entire fastening component 33 down and against the limiting plate 234 for limiting and fixing, thereby preventing the position of the forming plate 3 from moving, and ensuring that the fastening component 33 on it can remain against the abutment plate 23. The upward protruding force groove 34 on the forming plate 3 can strengthen the structural hardness of the forming plate 3, and can also guide the direction of water flow, so that the water can flow in a specific direction.

[0026] The beneficial effects of this utility model are as follows: The right end of the molding plate 3 is provided with an upward-lifting top part 31, and the left end of the molding plate 3 is provided with an upward-lifting overlapping part 32. One set of molding plates 3 is pressed onto the top part 31 of another set of molding plates 3 through the overlapping part 32 to form an overlapping connection and form a fastening assembly 33. The fastening assembly 33 fits into the contour edge of the receiving slot 2331, and is secured by a stud in the screw hole 2321 on the horizontal plate 232, so that the downward-lifting stud abuts against the overlapping part 32, pressing the entire fastening assembly 33 down and pressing it against the limiting plate 234 for limiting and fixing. The upper end of the connection between the fastening assembly 33 and the abutment plate 23 is blocked by the horizontal plate 232, so that the rainwater received can be guided along the downward tilting direction of the molding plate 3. Therefore, even if no sealant is added to the abutment of the fastening assembly 33 and the abutment plate 23, rainwater can be prevented from flowing in from there.

[0027] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
