Description

Technical Field

[0001] This invention relates to the field of roofing panel installation and seam correction technology, and in particular to a manual seam correction tool for improper installation of metal roofing seam panels. Background Technology

[0002] With the continuous advancement of building technology, users are not only paying more attention to the shape and aesthetics of buildings, but also have higher requirements for the waterproofing of building roofs.

[0003] Seamless roof panels are widely used in the roofing of large public buildings, public factories, prefabricated houses, and modular housing. Roof panels are generally divided into overlapping roof panels and seamless roof panels, with seamless roof panels gaining popularity due to their superior waterproofing performance. However, the installation of seamless roof panels is more complex than that of overlapping roof panels. Overlapping roof panels can be installed and waterproofed simply by overlapping the panels and fixing them with exposed nails. Seamless roof panels, on the other hand, require specialized manual seaming tools to initiate the seam, followed by specialized electric seaming equipment for final sealing. Depending on waterproofing requirements, some panel types require a single seam, while others require a second seam. Many factors influence the success of the seam sealing, including accurate installation dimensions, the flatness of the roof purlins, and the dimensions of the manufactured product. Therefore, the manual lockstitch correction tool of this application is mainly aimed at the lockstitch difficulties caused by the above-mentioned adverse factors. By correcting the lockstitch with the tool, the starting point of the lockstitch is made up to meet the requirements, so that the electric lockstitch machine rollers can move along the correct lockstitch size on the basis of manual lockstitch.

[0004] Metal roofing consists of many metal roofing panels continuously overlapped and arranged side by side on the roof. Each panel is generally quite long, requiring multiple people to lift it and overlap the female edge of the previous panel with the male edge. During the fastening process, due to improper dimensional control or issues with the panel's manufacturing angle, the shape of the overlap at the metal roofing panel may not meet the intended requirements. If the panels are manually clamped first, it's easy for the manual clamping to fail, leading to machine clamping failure.

[0005] Because the roofing seam is the final step in the entire roofing project, the preceding production, transportation, hoisting, installation, and fixing processes all affect the final seam fit. Furthermore, large-area roofs cannot be reworked due to unforeseen circumstances. Therefore, faced with numerous abnormalities, we can only try to correct them to bring the roof seams to the required standard.

[0006] To address this issue, this application presents an innovative manual starter lock seam correction tool that can overcome the difficulties in locking metal roof panels caused by various factors. Summary of the Invention

[0007] In order to overcome the deficiencies in the seam parameters caused by various factors before seam locking of metal roof panels in the prior art, this invention provides a more flexible compensation and correction tool that can effectively solve the seam locking problems encountered in the technical background.

[0008] A manual seam correction tool for improper installation of metal roof panels includes a rotatable manual seam correction tool with a manual seam clamping part and a handle. The tool is characterized by having metal plate correction tools on both sides of the manual seam clamping part, which are coaxial with the manual seam clamping part and connected as a whole by a metal tube. During operation, the metal tube is rotated by foot, causing the metal plate correction tools to correct the male and female seams of the metal roof panel to their correct positions.

[0009] Furthermore, in order to better realize the present invention, the manual lockstitch pliers and the metal plate straightening tool are connected together using the same shaft and can rotate concentrically, and can each perform their own functions independently.

[0010] Furthermore, in order to better realize the present invention, the manual lockstitch correction tool is provided with two sets of metal handles, one set being a handle for manual lockstitching, and there are two handles in total, one connected to the left clamp of the manual lockstitch pliers and the other connected to the right clamp of the manual lockstitch pliers.

[0011] Furthermore, in order to better realize the present invention, the other of the two sets of metal handles is a foot pedal handle, used to correct the position of the metal roof panel, and there is a total of one set, which is connected to the metal plate correction tools on both sides.

[0012] Furthermore, in order to better realize the present invention, the foot pedal handle is U-shaped as a whole, and a section extends outward on each side of the bottom of the U-shape, so that the operator can step on either side when using it.

[0013] Furthermore, in order to better realize the present invention, the normal position is to use a metal plate correction tool to forcibly correct and attach the poorly overlapping male and female joints of the metal roof panels to achieve a right angle position.

[0014] The beneficial effects of this invention are: Manual lockstitch pliers are no longer just for manual starting; they now include a correction function. Even with this added functionality, they remain easy to use and can still be operated by a single person. They can force poorly overlapping metal plates to right angles, providing a standardized base shape for subsequent mechanical starting and interlocking, greatly improving the success rate of electric lockstitch machines.

[0017] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of them. The components of the embodiments of the present invention described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0018] Therefore, the following detailed description of the embodiments of the invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the invention without inventive effort are within the scope of protection of the invention.

[0019] The following detailed description of some embodiments of the present invention is provided in conjunction with the accompanying drawings. Unless otherwise specified, the following embodiments and features can be combined with each other.

[0020] like Figure 5 The manual seam correction tool 2 shown includes a rotatable manual seam clamp 22 with a handle 23, a metal plate correction tool 24, a metal tube 25, etc. The rotatable manual seam clamp 22 and the metal plate correction tool 24 are connected together by the same shaft and can rotate concentrically.

[0021] To further clarify the specific structural features of this tool, in this embodiment, the manual seam correction tool 2 generally includes a manual seam clamping part 22 that fits into and is rotatably connected to the same central shaft, and a metal plate correction tool 24. The manual seam clamping part 22 consists of a left clamp and a right clamp located on opposite sides of each other, which cooperate to perform seam correction; the metal plate correction tool 24 is located at the front and rear ends of the manual seam clamping part 22, and is used to abut against the inner side of the male edge of the metal roof panel 1 before seam correction to perform position correction.

[0022] One side of the pliers body of the manual lockstitching pliers part 22 includes a right-angle plier plate in the shape of a "7", that is, the whole right-angle plier plate is 90 degrees, and several reference tongues are arranged at the upper left corner of the right-angle plier plate as the rotation carrier; the other side pliers body includes several rotating blocks fixed on one side of the top of the pressing plier plate, and the rotating blocks also serve as the rotation carrier.

[0023] The metal plate correction tool 24 includes two movable tongues in the front and back. Each movable tongue is fixed with a three-section jaw at the bottom. The jaw includes a vertical protruding section, a horizontal connecting section, and a correction section inclined inward and upward. The three are in the shape of a "ㄥ"; the two movable tongues in the front and back are facing the same direction and are fixedly connected by the metal tube 25 on the outside.

[0024] There are two handles 23 in total, which are respectively welded on the outer sides of the tops of the left pliers and the right pliers of the manual lockstitching pliers part 22, and handle sleeves are installed at the top ends. The reference tongues and the rotating blocks are staggered in the front and back. The central axis penetrates through the movable tongue, the reference tongue and the rotating block and rotates and connects them with each other. The pressing plier plate is of a straight plate structure, and the top ends of the front and back end faces have guide angles to facilitate the entry of the male and female edges of the metal roof panel 1.

[0025] In terms of structural dimensions, the included angle between the vertical side of one side of the manual lockstitching pliers part 22 and the corresponding side handle 23 is 145 degrees; the included angle between the plate surface of the pressing plier plate and the other side handle 23 is 154 degrees. The central plane of the metal tube 25 and the plate surface of the protruding section form an included angle of 66 degrees for easy pedaling; when the right-angle plier plate abuts against the female edge of the metal roof panel 1 and is vertically flush, the included angle between the two handles 23 is not greater than 53.6 degrees; when the pressing plier plate abuts perpendicularly against the female edge, the included angle between the two handles 23 is not greater than 41.4 degrees. The handle 23 is arranged on the manual lockstitching pliers part 22 to provide the torque for manual lockstitching; the metal tube 25 is arranged on the metal plate correction tool 24 and serves as a foot pedal for the operator to step on and press down.

[0026] It should be noted that a manual lockstitching and correcting tool for poor installation of metal roof panels in this application is a multi-functional correcting and manual starting tool. The manual lockstitching and correcting tool 2 has two functions. The first is the correcting function, and the second is the manual lockstitching function. When using it, it is necessary to strictly follow the order of manual correction first and then manual lockstitching.

[0027] As Figure 1 shown, for the metal roof panel 1 with poor lap joint caused by many adverse factors during buckling, it can be seen that the male and female edges are not correctly fitted. When using, the operator places the manual lockstitching and correcting tool 2 for poor installation of the metal roof panel on the metal roof panel 1 to be corrected and locked, and determines the position, as Figure 2 shown.

[0028] First, press the metal plate correction tool 24 of the manual seam correction tool 2 freely down onto the metal roof panel 1. Then, step down on the U-shaped metal tube 25. A section extends from each side of the bottom of the U-shape for easy foot placement, causing the poorly overlapping metal roof panel 1 to lift upwards at the male end of the tool and align with the female end. This correction action not only brings the male and female ends to their correct positions, but more importantly, it forces them to align and achieve a right angle. Figure 3 As shown.

[0029] After achieving the correct right-angle fit, manually rotate the handle 23 on the manual seam clamp 22, causing the clamp jaws to rotate along the central axis while still against the male and female openings of the metal roof panel 1. This ensures that the male and female openings of the metal roof panel 1 are rotated to a horizontal position. Figure 4 As shown. At this point, the jaws of the manual seam clamp 22 are completely fitted around the male and female joints of the metal plate. Because the metal plate correction tool 24 has positioned the male and female joints of the metal roof panel 1 at the correct right angle when the handle of the manual seam clamp 22 is turned, the shape of the seam is completely in line with requirements. Thus, the manual start-up of the previously non-compliant seam is completed.

[0030] Finally, place the electric seam-locking machine on the roof and close the rollers so that they fit against the horizontal male and female joints of the metal roof panel 1. Turn on the power switch, and the rollers of the electric seam-locking machine will rotate, causing the male and female joints of the metal roof panel 1 to continue to extend and form along the shape that has been manually corrected. Continue until the end of this metal roof panel is reached, and then start seaming the next metal roof panel 1. Repeat this process until the entire roof is completely seamed.

[0031] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit it. Any other modifications or equivalent substitutions made by those skilled in the art to the technical solutions of the present invention, as long as they do not depart from the spirit and scope of the technical solutions of the present invention, should be covered within the scope of the claims of the present invention.
