Background Art

[0002] The formwork system consists of three parts: a panel, a support, and a connecting piece, which can also be collectively referred to as a "formwork". The panel has a certain elastic deformation. During the operation process, the connecting piece is used as a positioning and reinforcement measure in formwork installation, so that various shapes can be made for components, and it is commonly used as a mold for concrete pouring. With the rapid development of engineering technology and the continuous innovation of concrete shapes, the quality requirements for formwork installation are getting higher and higher. The quality of formwork installation must consider the stiffness, strength, and stability of the connecting piece.

[0035] The panel 100 of the fair-faced concrete cross beam formwork is arranged around the outer sides of the concrete floor slab 200 and the concrete beam 300. The upper and lower beam main reinforcements 301 of the concrete beam are tied and connected by stirrups 302 to form a steel bar framework. The beam main reinforcement 301 at the upper end of the concrete beam 300 is located at the concrete floor slab 200. Secondary beam formwork ribs 303 and main beam formwork ribs 304 are sequentially laid at the outer side of the panel of the concrete beam 300.

[0036] The connecting main reinforcement 1 is located between the panel 100 and the steel bar framework, that is, outside the steel bar framework.
