Notched Wooden Beam Reinforcement for Structural Integrity

The patent applies local quality by providing a reinforcing portion only at the adjacent portion near the notch, rather than reinforcing the entire beam. This localized reinforcement specifically addresses the stress concentration area where cracking is most likely to occur, while leaving the rest of the beam structure unchanged. The reinforcing portion includes elements such as steel plates, angle iron, or channel iron that are attached to the beam body at the critical location.

The patent employs composite materials by combining wood (the beam body) with metal reinforcement materials (steel plates, angle iron, or channel iron). This composite structure leverages the compressive strength of wood and the tensile strength of metal to create a beam that can withstand the stress concentrations at the notch without cracking, thereby maintaining overall beam strength while accommodating the notch for device installation or sunken floor support.

The reinforcing portion is specifically positioned at the adjacent portion near the notch where stress concentration occurs, providing targeted reinforcement that prevents cracking in longer beams. This localized approach allows the beam to be extended in length for improved construction efficiency while the reinforcement at the critical location maintains reliability by preventing crack propagation.

The reinforcing portion is installed beforehand at the adjacent portion near the notch before the beam is subjected to loading or before the notch is cut. This preliminary reinforcement ensures that when the beam is later used in extended configurations, the critical area is already strengthened and resistant to cracking, allowing for safer and more efficient construction with longer beam spans.

The reinforcement is applied locally only at the adjacent portion near the notch rather than throughout the entire beam, minimizing the increase in device complexity. The reinforcing portion uses simple structural elements such as steel plates, angle iron, or channel iron that are attached using conventional fastening methods, thereby achieving cracking prevention without significantly complicating the overall beam structure.

The patent combines wood with metal reinforcement materials to create a composite beam structure. This approach maintains relative simplicity by using common construction materials and attachment methods, while the composite nature provides effective cracking prevention. The metal reinforcement elements are selected from standard structural shapes that are easy to install and integrate with wooden beams.
