Description

Technical Field

[0001] The utility model belongs to the technical field of template reinforcement, in particular to a reinforcement device for an arc beam template. Background Art

[0002] There are usually two traditional methods for installing and reinforcing the curved beam formwork of concrete structures:

[0003] Method 1: Customize a special standardized formwork and reinforcement system according to the arc shape and size of the curved beam of the concrete structure designed in the drawing, and install and reinforce it after transporting it to the site. This construction method cannot be recycled and reused due to the special arc shape and size, and is not economical.

[0004] Method 2: Use ordinary formwork for on-site processing. The reinforcement system is constructed with steel bars bent into corresponding curvatures and ordinary steel pipes with tension bolts. This construction method makes the curvature of the concrete structure beams prone to deviation and difficult to adjust. In addition, the bent steel bars cannot be used for engineering construction, resulting in material waste.

[0005] For example, a curved beam formwork reinforcement system disclosed in a Chinese utility model patent with an authorization announcement date of 2023.09.26 and an authorization announcement number of CN219753989U includes several main keels and several secondary keels, wherein the several main keels are distributed on both sides of the curved beam formwork, the several secondary keels respectively penetrate the curved beam formwork, and the two ends of the secondary keels are respectively fixedly connected to the main keels on both sides, the adjacent main keels are connected by bolts, and the bolts of adjacent main keels are connected by a rigid support ring.

[0006] The above-mentioned prior art can play a role in reinforcing the curved beam formwork, but has the following disadvantages:

[0007] 1. The main keels are connected by rigid support rings and bolts, which makes the installation operation complicated;

[0008] 2. The angle between the main keels is not easy to adjust;

[0009] 3. The secondary purlin needs to be cut according to the size of the gap between the template and the main purlin. It cannot be used in a circular manner, which wastes materials. In addition, errors are easily produced in measurement and cutting, resulting in the secondary purlin being too long or too short.

[0010] Therefore, how to facilitate operation, adjust the curvature, and use it flexibly are technical problems that need to be solved urgently. Utility Model Content
