In addition, the terms "first", "second" and the like are only used for descriptive purposes and cannot be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Thus, features defined as "first", "second" and the like may explicitly or implicitly include one or more of the features. In the description of the present invention, unless otherwise specified, "multiple" means two or more.

[0025] In the description of the present invention, it should be noted that, unless otherwise expressly specified or limited, the terms "installed," "connected," and "connected" should be understood in a broad sense. For example, they can refer to fixed connections, detachable connections, or integral connections; they can refer to mechanical connections or electrical connections; they can refer to direct connections or indirect connections through an intermediate medium; and they can refer to internal connections between two components. Those skilled in the art can understand the specific meanings of the above terms in the present invention based on specific circumstances.

[0026] The present invention will be described in detail below with reference to the accompanying drawings and in combination with embodiments.

[0027] A simple portable arch frame connecting plate positioning tool, such as Figures 1 to 7 As shown, it includes a front positioning plate 1, a rear positioning plate 2 and a holding rod 3 therebetween. The rear positioning plate is lower in height than the front positioning plate, and a positioning mechanism 4 is provided on the front side of the front positioning plate; the positioning mechanism includes two positioning rods 5 arranged in parallel, and a contact plate 6 is detachably installed at the front end of the positioning rod; adjustment parts 7 are detachably installed on the left and right sides of the front positioning plate, and on the left and right sides of the rear positioning plate; a matching rod 9 corresponding to the positioning rod is provided on the side of the contact plate facing the positioning rod, and a socket 10 matching the matching rod is provided on the positioning rod.

[0028] As an example, the adjustment part includes a screw that is threaded onto the front positioning plate / rear positioning plate. By screwing the adjustment part, the outer end of the adjustment part is pressed against the web of the I-beam, which ensures that the tool has good stability. Usually, the outer end of the adjustment part is provided with an external hexagonal nut structure. When the tool is installed in the groove of the web of the I-beam, it can be conveniently screwed with a wrench. The arch connecting plate can be fixed at the positioning mechanism. The holding rod is made of steel bars. By manually holding the holding rod, the tool can be conveniently arranged in the groove of the web of the I-beam. It is easy to operate, can reduce the physical strength consumed by the user, reduce the number of manpower, and improve work efficiency.

[0029] The upper edge of the gripping rod is flush with the end surface of the rear positioning plate. A bottom plate 11 is provided between the front positioning plate and the rear positioning plate, and the two ends of the bottom plate are respectively connected with the bottom of the front positioning plate and the bottom of the rear positioning plate.

[0030] Four legs 12 are symmetrically positioned on the lower end of the base. In an optional embodiment, the legs include a base 13 fixed to the base, with an adjustable seat 14 threadedly attached to the lower end of the base. Typically, the adjustable seat has a threaded rod 8 at its upper end, and a threaded hole in the base that mates with the rod. The adjustable seat can be adjusted by changing the length of engagement between the rod and the hole in the base, thereby varying the overall height of the legs and, consequently, the height of the tooling.

[0031] During construction, the welder holds the gripping rod of the arch frame connection plate positioning tool, places the tool into the groove of the I-beam web, and hangs the arch frame connection plate on the contact plate. The welder then uses his hands to press the arch frame connection plate so that the arch frame connection plate fits the end face of the I-beam. At this time, the arch frame connection plate fits the contact plate, improving the installation accuracy of the arch frame connection plate. Then, welding can be carried out. The operation is simple and convenient, and the labor workload is reduced. Of course, when the contact plate is not needed, the contact plate can be removed and the two positioning rods can be used to contact the arch frame connection plate, or the arch frame connection plate can be directly hung on the two positioning rods.

[0032] The positioning tool provided by the invention is simple and convenient to operate, and the tool is simple to manufacture, easy to store, and reusable. When used, the tool only needs to be placed in the groove of the I-beam web, and the welder can operate it alone, which effectively reduces the workload of construction workers and improves work efficiency.

[0033] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
