Description

Technical Field

[0001] The utility model relates to the technical field of arc adjustment, in particular to an arc adjustment template. Background Technique

[0002] When processing the bottom formwork of a cylindrical capping beam, the material utilization rate is very low. Usually, a circle with the same diameter as the cylinder needs to be cut off. If the formwork for different diameters is processed separately, it will cause great waste of resources. In the comparative case, the publication number is CN211114781U. The utility model relates to an adjustable arc building formwork, which includes a plurality of adjusting brackets connected in sequence end to end and a wooden formwork placed on the adjusting brackets. The adjusting bracket includes a back rib and two adjusting members. The two adjusting members are respectively fixedly arranged on both sides of the back rib. The adjusting member includes two adjusting plates. The two adjusting plates are fixedly parallel to one side of the back rib. The first hinge hole and the second hinge hole are respectively opened on the two adjusting plates. The two adjusting plates in one adjusting bracket are clamped in the two adjusting plates in another adjusting bracket, and the connection of the two adjusting brackets is realized by inserting a first hinge shaft into the first hinge hole. The second hinge shaft is arranged in the second hinge hole. A fixing seat is detachably arranged on each second hinge shaft. A threaded hole is opened on the fixing seat. A lead screw sleeved with a nut is connected between the threaded hole in one adjusting bracket and the threaded hole in another adjusting bracket, achieving the purpose of simple structure and capable of infinitely adjusting the angle between two adjacent formworks.

[0003] However, it is found that the above-mentioned adjustable arc building formwork has the following problems in the implementation of related technologies. By opening a threaded hole on the fixing seat and connecting a lead screw sleeved with a nut between the threaded hole in one adjusting bracket and the threaded hole in another adjusting bracket, it achieves a simple structure and can infinitely adjust the angle between two adjacent formworks. The existing arc formwork cannot be adjusted for different diameters for processing and pouring, reducing the sharing of the bottom formworks of cylindrical capping beams with two diameters.

[0004] Therefore, it is necessary to design and transform the arc formwork to effectively prevent the problem that the arc formwork cannot be adjusted for different diameters for processing and pouring. Content of the Utility Model

[0005] To solve the problems raised in the above background technique, the purpose of the present utility model is to provide an arc adjustment template, which has the advantage of convenient adjustment and solves the problem that the arc formwork cannot be adjusted for different diameters for processing and pouring.

[0007] A circular plate;

[0008] The surface of the circular plate is wrapped with an annular plate, and adjusting mechanisms are slidably connected to both the left and right sides of the inner cavity of the annular plate;

[0009] The adjusting mechanism includes an arc-shaped plate, a connecting plate, an inclined slot, a handle, and a plug rod. Arc-shaped plates are slidably connected to both the left and right sides of the inner cavity of the annular plate. A connecting plate is fixedly connected to the left side of the arc-shaped plate and inside the annular plate. An inclined slot is formed on the surface of the connecting plate. Handles are slidably connected to both the left and right sides of the front end of the arc-shaped plate. A plug rod is fixedly connected to the bottom of the handle, and the bottom of the plug rod penetrates into the inside of the inclined slot.
