AI Technical Summary

Technical Problem

Existing molds have problems in the pouring of precast concrete base slabs for assembling integral two-way dense rib composite floor slabs, such as insufficient accuracy in rebar positioning, poor structural adaptability, easy damage during demolding, and insufficient stability during vibration.

Method used

The mold design includes a base plate, a first intermediate plate, a second intermediate plate, a first side plate, a second side plate, and a third side plate. Through structures such as protruding plates, rib positioning grooves, and rib stirrup holes, it can achieve quick positioning and disassembly, which is convenient for demolding. Q235 steel is used to ensure strength and toughness.

Benefits of technology

It improves the speed and efficiency of pouring, reduces construction errors, lowers construction difficulty, and enables efficient construction of prefabricated buildings.
