Description

Technical Field

[0001] The utility model belongs to the technical field of building construction, in particular to a formwork supporting device for building construction. Background Art

[0002] In construction projects, there are many situations where concrete needs to be poured by constructing supporting formwork. These supporting formworks require supporting devices to fix the supporting formworks during construction. However, existing formwork supports for construction have some obvious problems and shortcomings. Existing formwork supports for construction are generally divided into non-modular formwork supports and modular formwork supports.

[0003] Non-modular formwork supports are extremely inconvenient to transport due to their non-disassembly characteristics. Furthermore, their fixed-size design means they can only be used with support formwork of a single size, which undoubtedly limits their scope of application. When faced with support formwork of different sizes and shapes, formwork supports of different specifications must be prepared, which not only increases costs but also reduces construction efficiency.

[0004] Modular formwork is usually assembled using studs. Although studs can connect modules, their bearing capacity is limited. When pouring concrete, due to the pressure of the concrete and the weight of the supporting formwork, the studs are often easily bent, which affects the stability of the formwork.

[0005] More importantly, neither non-modular formwork nor modular formwork can effectively prevent the problem of tilting of the supporting formwork. Once the supporting formwork tilts, it will not only affect the quality of concrete pouring, but may even cause safety accidents. Utility Model Content
