AI Technical Summary
Traditional reinforced brick lintels are not convenient for secondary reinforcement in doorway reinforcement, and their smooth surface makes it difficult for concrete mortar to adhere.
Square steel is used as the bottom of the lintel, with an inner steel tube embedded inside and a decorative panel on the surface. The decorative panel has hollowed-out holes and tapered protrusions to increase roughness, and is fixed with screws. The inner steel tube is snapped into the top stop to improve the load-bearing capacity.
It improves the load-bearing capacity of the lintel and the adhesion of the concrete mortar, facilitates on-site cutting and installation, and realizes convenient reinforcement of the lintel.
