[0031] Specifically, the specifications of the U-shaped embedded reinforcement 3 are

[0032] Working principle:

[0033] Two adjacent concrete foundations 1 are connected by pre-embedded perforated steel plates 5 and bolts. Bolts need to be reserved for the middle concrete foundation 1 according to the commonly used construction elevator model, so as to quickly and conveniently connect the elevator with the concrete foundation 1;

[0034] Before installation at the construction site, a fine sand leveling layer must be laid at the base position of the elevator, and the concrete foundation 1 must be hoisted to the foundation installation position using equipment such as a tower crane or a car crane. After it is in place, the concrete foundation 1 is spliced ​​using accessories such as I-beams 4, angle steel connectors 2, and bolt assemblies. After the connection is completed, the elevator is installed using reserved bolts or embedded parts. This method not only reduces the construction process, but also improves construction efficiency, increases turnover times, saves construction costs, saves energy, and also saves materials. While reducing construction waste, it also reduces noise pollution, meets the requirements for green construction development, and achieves the unity of economic benefits, social benefits, and environmental benefits.
