They are used only for the convenience of describing this utility model and do not require that this utility model be constructed and operated in a specific orientation; therefore, they should not be construed as limitations on this utility model. The terms "connected" and "linked" used in this utility model should be interpreted broadly. For example, they can refer to a fixed connection or a detachable connection; they can refer to a direct connection or an indirect connection through intermediate components. Those skilled in the art can understand the specific meaning of the above terms according to the specific circumstances.

[0034] The present invention will now be described in detail with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described herein can be combined with each other.

[0035] This embodiment aims to provide a positioning fixture for steel frame connecting plates in a steel frame processing plant. Its main function is to assist workers in welding the connecting plates to the ends of the steel frame, ensuring that the connecting plates are not welded crookedly, and ensuring the stability of the connection between steel arch frame segments.

[0036] Referring to Figures 1-5, the system includes: a calibration plate 1 and a positioning plate 3. The calibration plate 1 is rectangular, and its dimensions are the same as those of the connecting plate 11 of the steel frame. The steel frame is usually an arc-shaped I-beam. The calibration plate 1 and the connecting plate 11 are attached together by positioning elements 2. Specifically, the positioning elements 2 are bolts, so that the surface of the calibration plate 1 has four alignment holes, two on the left and two on the right. The four alignment holes correspond to the four existing mounting holes on the connecting plate 11 to ensure that the edges of the calibration plate 1 and the connecting plate 11 are aligned. The alignment holes and mounting holes are covered by the bolt structure in the figures and are not shown.

[0037] The center of the surface of the alignment plate 1 is provided with a U-shaped notch 4, which is adapted to the size of the outer contour of the steel frame, so that the alignment plate 1 can slide along the extension direction of the steel frame, so that the alignment plate 1 can be fastened to the back of the steel frame and centered. By sliding the alignment plate 1, the connecting surface of the connecting plate 11 can be seamlessly contacted with the end face of the steel frame, so as to ensure the welding quality of the connecting plate 11 and the end face of the steel frame. The purpose of centering the alignment plate 1 is to ensure that the end face of the connecting plate 11 and the steel frame are also centered and connected, thereby playing a role in position alignment.

[0038] One end of the positioning plate 3 is welded to one side of the alignment plate 1 and set on top. The extension direction of the positioning plate 3 is consistent with the steel frame so that the positioning plate 3 can be tightly attached to the back of the arc-shaped steel frame, i.e. the outer arc surface. At the same time, the positioning plate 3 is fixed on the steel frame by the tightening mechanism, so that the worker can take it off and it is extremely convenient.

[0039] Specifically, the width of the positioning plate 3 is the same as the width of the steel frame. The clamping mechanism includes a bracket and a top pressure rod 7. The bracket is composed of a pair of L-shaped plates 6. The two L-shaped plates 6 are symmetrically arranged in the middle of both sides of the positioning plate 3, and the interval between the short plates of the two L-shaped plates 6 is not less than the thickness of the web of the steel frame to avoid interference between them. The long plates of the two L-shaped plates 6 are parallel to the web of the steel frame, and the ends of the long plates of the two L-shaped plates 6 away from their short plates are perpendicular to the positioning plate 3. They are fixed to the middle of the side of the positioning plate 3 by bolts. The purpose is to quickly separate the L-shaped plates 6 from the positioning plate 3 so that this fixture can be removed from the steel frame.

[0040] Both short plates of the two L-shaped plates 6 extend vertically toward the web of the steel frame. The top pressure rod 7 passes vertically through the center of the short plate of the L-shaped plate 6. The end of the top pressure rod 7 extending toward the positioning plate 3 is perpendicularly connected to the pressure plate 8 to increase the contact area of ​​the head of the top pressure rod 7. The end of the top pressure rod 7 away from the positioning plate 3 is provided with a pull ring 9. The pull ring 9 allows the worker to easily pull the top pressure rod 7 to adjust the distance between its head and the positioning plate 3. At the same time, it can also cooperate with the pressure plate 8 to prevent the top pressure rod 7 from falling off the L-shaped plate 6. A reaction spring 10 is provided between the pressure plate 8 and the short plate of the L-shaped plate 6. The reaction spring 10 is sleeved on the outside of the top pressure rod 7. The reaction spring 10 presses the pressure plate 8 against the wing plate of the steel frame.

[0041] In this embodiment, the back of the positioning plate 3 is provided with an arc-shaped handle 5 along the length of the steel frame so that the worker can carry the tool.

[0042] In this embodiment, the top pressure rod 7 can be a top screw, which is threaded onto the short plate of the L-shaped plate 6. This eliminates the need for the installation of the reaction spring 10. In comparison, using the reaction spring 10 makes this fixture more flexible, but the positioning method still needs to be selected according to the actual working conditions.

[0043] In actual use, first align and install the connecting plate 11 and the positioning plate 1 together, then fasten the positioning plate 1 to the connecting end of the steel frame, and ensure that the connecting plate 11 is in close contact with the end face of the steel frame. At this time, the positioning plate 3 is tightly against the back of the steel frame. Install the L-shaped plates 6 simultaneously or sequentially on the left and right sides of the positioning plate 3 using bolts or studs. The bolts can be of a longer type, so that the bolt shank can pass through the positioning plate 3, thus enabling the simultaneous installation of two L-shaped plates 6. The stud installation method involves directly threading the studs to the positioning plate 3. In short, the L-shaped plates 6 and the positioning plate 3 are pressed and fixed. Finally, the reaction spring 10 is used to press the head of the top pressure rod 7 against the wing plate of the steel frame to weld the contact position between the connecting plate 11 and the end face of the steel frame.

[0044] It is understood that the above description is merely exemplary and the embodiments of this application do not limit the scope of the application.

[0045] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model shall be within the scope of protection of the pending claims of the present utility model.
