Description

Technical Field

[0001] This utility model relates to the field of building construction technology, and in particular to a pre-formed steel formwork with pre-reinforced steel grooves. Background Technology

[0002] Pre-formed steel formwork with pre-reserved grooves for reinforcing bars is an important tool for concrete pouring and shaping in building construction. Its surface is pre-set with grooves for reinforcing bars to pass through or be positioned, which can accurately fix the position of the reinforcing bars during the concrete pouring process and ensure the effective bonding between the reinforcing bars and the concrete structure.

[0003] When using pre-reinforced steel formwork with pre-reserved grooves for reinforcing bars, the formwork must first be assembled and fixed according to construction requirements. Then, the reinforcing bars are passed through the pre-reserved grooves on the formwork to position and limit their movement, preventing displacement during concrete pouring. Next, concrete is poured into the formwork. Once the concrete reaches the specified strength, the steel formwork is removed, forming a reinforced concrete component. The pre-reserved grooves leave channels on the surface of the component that match the reinforcing bars, meeting the needs of subsequent reinforcing bar connections or other structural installations. However, when encountering requirements for rebar depth, the construction team has to replace the steel formwork with the corresponding specifications. This not only increases equipment procurement costs and inventory pressure but also leads to construction interruptions and extended construction periods due to frequent formwork replacements. Therefore, to solve this problem, we propose pre-reinforced steel formwork with pre-reserved grooves for reinforcing bars. Utility Model Content
