Thermally Insulating Cantilever Slab Connection with U-Bolt Anchoring

The patent combines multiple pull-out safeguards into a single integrated U-bolt structure. The U-bolt has two legs that wrap around the steel profile and are anchored into the concrete, creating a unified component that provides multiple anchoring points simultaneously. This merging approach achieves the required resistance against pull-out forces while avoiding the complexity of installing separate safeguards for each direction.

The U-bolt serves multiple functions: it acts as a pull-out safeguard, a connector between the steel profile and the concrete, and a structural element that distributes loads. By designing a single component that performs multiple functions, the patent reduces the overall number of parts needed while maintaining or improving the resistance against pull-out forces.

The U-bolt acts as an intermediary element between the simple straight steel profile and the concrete structure. Instead of modifying the steel profile itself (which would compromise its manufacturing simplicity and thermal insulation properties), the U-bolt provides the necessary anchoring function by wrapping around the profile and embedding into the concrete, thus mediating the connection while leaving the steel profile unchanged.

The patent transitions from a one-dimensional solution (modifying the steel profile with elevations) to a three-dimensional solution (wrapping the U-bolt around the profile in multiple directions). The U-bolt's legs extend in different spatial dimensions, providing anchoring in multiple directions without altering the steel profile's simple linear form.

The patent optimizes the geometric parameters of the U-bolt, such as the leg length, wrap angle, and anchor depth, to maximize its load-bearing capacity. By carefully selecting these parameters, the simplified U-bolt structure achieves sufficient strength to absorb shear forces and moment forces while maintaining manufacturing simplicity.

The connection system combines different materials with complementary properties: the steel profile provides tensile strength, the U-bolt provides anchoring and load distribution, and the concrete provides compressive strength and anchoring medium. This composite approach allows each component to be simple in its own right while collectively achieving the required strength to absorb various types of forces.
